Most of the written info is the same all the time, but memset(0) is very wrong. If ->sigq is queued we can race with collect_signal() which can fail to find this siginfo looking at .si_signo, or copy_siginfo() can copy the wrong .si_code/si_tid/etc. In short, sys_timer_settime() can in fact stop the active timer, or the user can receive the siginfo with the wrong .si_xxx values. Move "memset(->info, 0)" from posix_timer_event() to alloc_posix_timer(), change send_sigqueue() to set .si_overrun = 0 when ->sigq is not queued. It would be nice to move the whole sigq->info initialization from send to create path, but this is not easy to do without uglifying timer_create() further. As Roland rightly pointed out, we need more cleanups/fixes here, see the "FIXME" comment in the patch. Hopefully this patch makes sense anyway, and it can mask the most bad implications.

What do you think? restore_fpu_checking() calls init_fpu() in error conditions. While this is wrong(as our main intention is to clear the fpu state of the thread), this was benign before commit 92d140e21f1 ("x86: fix taking DNA during 64bit sigreturn"). Post commit 92d140e21f1, live FPU registers may not belong to this process at this error scenario. In the error condition for restore_fpu_checking() (especially during the 64bit signal return), we are doing init_fpu(), which saves the live FPU register state (possibly belonging to some other process context) into the thread struct (through unlazy_fpu() in init_fpu()). This is wrong and can leak the FPU data.

If there is no reserved block at all, we shouldn't need to do so. But current code still tries to release the reserved blocks regardless whether the counters's value is 0. Continue to do that causes the later calculation to go wrong and a kernel BUG_ON() caught that. This doesn't happen for extent-based files, as the calculation for 0 reserved blocks was right for extent based file. This patch fixed the kernel BUG() due to above reason.

Some of the flex groups searched have free blocks and free inodes, but the flex_freeb_ratio is < 10, so they're skipped. Then when a group is compared to the current "best" flex group, it does not have more free blocks than "best", so it is skipped as well. This continues until no flex group with free inodes is found which has a proper ratio or which has more free blocks than the "best" group, and we're left with a "best" group that has 0 inodes free, and we return -ENOSPC.

The current calculation of how many index/leaf blocks should be accounted is too conservetive, it always considered the worse case, where the tree level is 5, and in the case of multiple chunk allocations, it always assumed no blocks were dirtied in common across the allocations. This path uses the accurate depth of the inode with some extras to calculate the index blocks, and also less conservative in the case of multiple allocation accounting.

This patch uses the helper function in DIO and fallocate case, passing a flag indicating that the modified data are contigous thus could account less indirect/index blocks. This patch also fixed the journal credit reservation for direct I/O (DIO). Previously the estimated credits for DIO only was calculated for non-extent files, which was not enough if the file is extent-based. Also fixed was fallocate double-counting credits for modifying the the superblock.

This makes sure we don't take too much journal credits during writeout. We also don't limit the pages to write. That means we loop through the dirty pages building largest possible contiguous block request. Then we issue a single get_block request. We may get less block that we requested. If so we would end up not mapping some of the buffer_heads. That means those buffer_heads are still marked delay. Later in the writepage callback via __mpage_writepage we redirty those pages. We should also not limit/throttle wbc->nr_to_write in the filesystem writepages callback.

Since we didn't know exactly how many blocks would need to be allocated, the estimated journal credits required was very conservative and caused many issues. With the reworked delayed allocation, a new transaction is created for each get_block(), thus we don't need to guess how many credits for the multiple chunk of allocation. We start every transaction with enough credits for inserting a single exent. When estimate the credits for indirect blocks to allocate a chunk of blocks, we need to know the number of data blocks to allocate. We use the total number of reserved delalloc datablocks; if that is too big, for non-extent files, we need to limit the number of blocks to EXT4_MAX_TRANS_BLOCKS. Code cleanup from Aneesh.

Therefore it is never necessary to traverse through a node more than once to get a correct answer to the given query. Take advantage of this property using a global ID counter so that we need not clear all the markers in all the lock_class entries before doing a traversal. A new ID is choosen when we start to traverse, and we continue through a lock_class only if it's ID hasn't been marked with the new value yet. This short-circuiting is essential especially for high CPU count systems. The scheduler has a runqueue per cpu, and needs to take two runqueue locks at a time, which leads to long chains of backwards and forwards subgraphs from these runqueue lock nodes. Without the short-circuit implemented here, a graph traversal on a runqueue lock can take up to (1 << (N - 1)) checks on a system with N cpus. For anything more than 16 cpus or so, lockdep will eventually bring the machine to a complete standstill. Signed-off-by: David S.

A recent patch allowed do_md_stop to know whether it was being called via an ioctl or not, and thus where to allow for an extra open file descriptor when checking if it is in use. This broke then switch to readonly performed by the shutdown notifier, which needs to work even when the array is still (apparently) active (as md doesn't get told when the filesystem becomes readonly). So restore this feature by pretending that there can be lots of file descriptors open, but we still want do_md_stop to switch to readonly.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The raid10 resync/recovery code currently limits the amount of in-flight resync IO to 2Meg. This was copied from raid1 where it seems quite adequate. However for raid10, some layouts require a bit of seeking to perform a resync, and allowing a larger buffer size means that the seeking can be significantly reduced. There is probably no real need to limit the amount of in-flight IO at all. Any shortage of memory will naturally reduce the amount of buffer space available down to a set minimum, and any concurrent normal IO will quickly cause resync IO to back off. The only problem would be that normal IO has to wait for all resync IO to finish, so a very large amount of resync IO could cause unpleasant latency when normal IO starts up. So: increase RESYNC_DEPTH to allow 32Meg of buffer (if memory is available) which seems to be a good amount. Also reduce the amount of memory reserved as there is no need to keep 2Meg just for resync if memory is tight. Thanks to Keld for the suggestion.

The lowmem mapping table created by VMI need not depend on max_low_pfn at all. Instead we now create an extra large mapping which covers all possible lowmem instead of the physical ram that is actually available. This allows the vmi initialization to be done before max_low_pfn could be computed. We also move the vmi_init code very early in the boot process so that nobody accidentally breaks the fixmap dependancy. Signed-off-by: Alok N Kataria Acked-by: Zachary Amsden Signed-off-by: H.

Since the start of the vmalloc area is not at a fixed address (but the vmalloc end address is, via the per-platform VMALLOC_END define), a default area of 128M is reserved for vmalloc mappings, which can be shrunk or enlarged by passing an appropriate vmalloc= command line option as it is done on x86. On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000, two 512M RAM banks and vmalloc=128M (the default), this patch gives: Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap). Memory: 512MB 352MB = 864MB total On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe800000, two 256M RAM banks and vmalloc=768M, this patch gives: Truncating RAM at 00000000-0fffffff to -0e7fffff (vmalloc region overlap). Ignoring RAM at 10000000-1fffffff (vmalloc region overlap).

However, take extra care with double_lock_balance() as it can release the already held rq->lock (and therefore change its nesting class). So what can happen is: spin_lock(rq->lock); // this rq subclass 0 double_lock_balance(rq, other_rq); // release rq // acquire other_rq->lock subclass 0 // acquire rq->lock subclass 1 spin_unlock(other_rq->lock); leaving you with rq->lock in subclass 1 So a subsequent double_lock_balance() call can try to nest a subclass 1 lock while already holding a subclass 1 lock. Fix this by introducing double_unlock_balance() which releases the other rq's lock, but also re-sets the subclass for this rq's lock to 0.

As pointed out and tracked by Yinghai Lu : Dhaval Giani got: kernel BUG at arch/x86/kernel/io_apic_64.c:357! invalid opcode: 0000 [1] SMP CPU 24 ... his system (x3950) has 8 ioapic, irq > 256 This was caused by: commit 9b7dc567d03d74a1fbae84e88949b6a60d922d82 Author: Thomas Gleixner Date: Fri May 2 20:10:09 2008 +0200 x86: unify interrupt vector defines The interrupt vector defines are copied 4 times around with minimal differences. Move them all into asm-x86/irq_vectors.h It appears that Thomas did not notice that x86_64 does something completely different when he merge irq_vectors.h We can solve this for 2.6.27 by simply reintroducing the old heuristic for setting NR_IRQS on x86_64 to a usable value, which trivially removes the regression. Long term it would be nice to harmonize the handling of ioapic interrupts of x86_32 and x86_64 so we don't have this kind of confusion. Dhaval Giani tested an earlier version of this patch by YH which confirms simply increasing NR_IRQS fixes the problem. Signed-off-by: Eric W.

Directly embed an estimator object into every stats object and switch to using the kernel-provided list implementation. This makes the code much simpler and faster, as we do not need to traverse the list of all estimators to find the one belonging to a stats object. There's no need to use an rwlock, as we only have one reader. Also reorder the members of the estimator structure slightly to avoid padding overhead. This can't be done with the stats object as the members are currently copied to our user space object via memcpy() and changing it would break ABI.

Nice debugging work. I'd suggest something like the attached (boot tested) patch as the simple fix for now. I expect the benefits from the less synchronized, multiple-in-flight-data global queue will still outweigh the costs of dynamic allocations. But if worst comes to worst then we just go back to a globally synchronous one-at-a-time implementation, but that would be pretty sad!

This fix also solves the problem with x86-microcode. I've sent alternative patches for microcode, but as this "rely on set_cpus_allowed_ptr() being workable in cpu-hotplug(CPU_ONLINE, ...)" assumption seems to be more broad than what we thought, perhaps this fix should be applied. With this patch we define that by the moment CPU_ONLINE is being sent, a 'cpu' is online and ready for tasks to be migrated onto it.

But in the current code, we execute the fallback path only when pci_register_driver() itself fails, which is unrelated to whether any matching devices were found. This patch counts the AGP bridges found in the probe() method and executes the fallback path when none is found.

This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.

While trying to optimize the boot speed of my laptop, I have been loving number 3 to figure out what to optimize... ... and then I wished that the same thing was done for module loading.

The irq handler of hvc_console calls hvc_poll and hvc_kill which might take the hvc_struct spinlock. Therefore, we have to call request_irq outside the spinlock. We can move the notifier_add safely outside the spinlock as ->data must not be changed by the backend. Otherwise, tty_hangup would fail anyway.

OK indeed it did have a couple of bugs. Firstly, I wasn't freeing the data properly in the alloc && wait case. Secondly, I wasn't resetting CSD_FLAG_WAIT in the for each cpu loop (so only the first CPU would wait). After those fixes, the patch boots and runs with the kmalloc commented out (so it always executes the slowpath).

This mapping is not enabled until the architecture specific cpu_init() function is run, which causes problems since some generic code is run before this point. In particular when CONFIG_PRINTK_TIME is enabled, the boot cpu will trap on the access to per-cpu memory at the first printk() call so the boot will fail without the kernel printing anything to the console. Fix this by allocating percpu memory for cpu0 in the kernel data section and doing all initialization to enable percpu access in head.S before calling any generic code. Other cpus must take care not to access per-cpu variables too early, but their code path from start_secondary() to cpu_init() is all in arch/ia64 Signed-off-by: Tony Luck --- arch/ia64/kernel/head.S | 26 +++++++++++++++++++++++++- arch/ia64/kernel/setup.c | 18 ++++++++++-------- arch/ia64/kernel/smpboot.c | 2 ++ arch/ia64/kernel/vmlinux.lds.S | 3 +++ arch/ia64/mm/contig.c | 10 ++++++++-- arch/ia64/mm/discontig.c | 6 +++++- 6 files changed, 53 insertions(+), 12 deletions(-) diff --git a/arch/ia64/kernel/head.S b/arch/ia64/kernel/head.S index 41c712917ff7..8bdea8eb62e3 100644 --- a/arch/ia64/kernel/head.S +++ b/arch/ia64/kernel/head.S @@ -359,7 +359,31 @@ start_ap: mov ar.rsc=0 // place RSE in enforced lazy mode ;;

In the reset state, however, it is not allowed to post SQ WQEs, which confuses applications like ib_mad.

To avoid this problem, the driver needs to detect the second CQE and discard it. For this purpose, introduce an array holding as many elements as the SQ of the QP, called sq_map. Each sq_map entry stores a "reported" flag for one WQE in the SQ. When a work request is posted to the SQ, the respective "reported" flag is set to zero. After the arrival of a CQE, the flag is set to 1, which allows to detect the occurence of a second CQE. The mapping between WQE / CQE and the corresponding sq_map element is implemented by replacing the lowest 16 Bits of the wr_id with the index in the queue map. The original 16 Bits are stored in the sq_map entry and are restored when the CQE is passed to the application.

This is set up in arch_prepare_hugepage(), which is called from alloc_fresh_huge_page_node(). A similar call to arch_prepare_hugepage() is missing for surplus large pages that are allocated in alloc_buddy_huge_page(), which breaks the software emulation mode for (surplus) large pages on s390. This patch adds the missing call to arch_prepare_hugepage(). It will have no effect on other architectures where arch_prepare_hugepage() is a nop.

A struct file_region is used to track when reservations have been consumed and where. These file_regions are allocated as necessary with kmalloc() which can sleep with the mm->page_table_lock held. This is wrong and triggers may-sleep warning when PREEMPT is enabled. Updates to the underlying file_region are done in two phases. The first phase prepares the region for the change, allocating any necessary memory, without actually making the change. The second phase actually commits the change. This patch makes use of this by checking the reservations before the page_table_lock is taken; triggering any necessary allocations. This may then be safely repeated within the locks without any allocations being required. Credit to Mel Gorman for diagnosing this failure and initial versions of the patch.

The FIFO begins to backup until it becomes full. What happens next is the radeon_fifo_wait() times out, and we access the chip illegally leading to a bus error which usually wedges the box.

This will only happen if you 1) VC switch or 2) run "consolechars" or 3) unblank the screen. This seems to happen because until a redraw_screen() the screen scrolling method used by fbcon is not finalized yet. I've seen this with other fb drivers too. So if all you do is boot straight into X you will never see this bug on the relevant chips. Signed-off-by: David S.

This needs to be fixed so that the source files remain usable and good examples of code instead of bad examples. Add the ability to build source files that are in the Documentation/ dir. Add to Kconfig as "BUILD_DOCSRC" config symbol. Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the Documentation/ sources. Or enable BUILD_DOCSRC in the *config system. However, this symbol depends on HEADERS_CHECK since the header files need to be installed (for userspace builds). Built (using cross-tools) for x86-64, i386, alpha, ia64, sparc32, sparc64, powerpc, sh, m68k, & mips.

The problem appears to be that the patched file ends up as part of the target toolchain, but unfortunately the gcc constant folding doesn't appear to eliminate the __invalid_size_argument_for_IOC value early enough. Certainly compiling C++ programs which use _IO... macros as constants fails without this patch.

While this is correct for isolated contexts, there's no need to enforce the npc restriction on non-isolated NOSCHED contexts. This means that NOSCHED contexts can only ever run with an entry point of 0x0. This change to spu_run_init allows setting of the npc (and, while we're at it, the privcntl) for non-isolated NOSCHED contexts. This allows us to run NOSCHED contexts from any entry point.

It will deadlock in xfs_iomap_write_allocate() trying to take the ilock we already hold. This can also show up as complex ABBA deadlocks when multiple threads are triggering memory reclaim when trying to allocate extents. The main cause of this is the fact that delayed allocation is not done in a transaction, so KM_NOFS is not automatically added to the allocations to prevent this recursion. Mark all allocations done for the incore inode extent tree as KM_NOFS to ensure they never recurse back into the filesystem.

Except for the sorting of the inodes this logic is implemented in xfs_lock_inodes, but also partially duplicated in xfs_lock_dir_and_entry in a particularly stupid way adds a lock roundtrip if the inode ordering is not optimal. This patch adds a new helper xfs_lock_two_inodes that takes two inodes and locks them in the most optimal way according to the above locking protocol and uses it for all places that want to lock two inodes. The only caller of xfs_lock_inodes is xfs_rename which might lock up to four inodes.

Setting up the xfs_inode <-> inode link is opencoded in xfs_iget_core now because that's the only place it needs to be done, xfs_initialize_vnode is renamed to xfs_setup_inode and loses all superflous paramaters. The check for I_NEW is removed because it always is true and the di_mode check moves into xfs_iget_core because it's only needed there. xfs_set_inodeops and xfs_revalidate_inode are merged into xfs_setup_inode and the whole things is moved into xfs_iops.c where it belongs.

It mixed exclusive access with completion. That is, we need to mark an object as being flushed before flushing it to disk, and then block any other attempt to flush it until the completion occurs. We do this but adding an extra count to the completion before we start using them. However, we still need to determine if there is a completion in progress, and allow no-blocking attempts fo completions to decrement the count. To do this we introduce: int try_wait_for_completion(struct completion *x) returns a failure status if done == 0, otherwise decrements done to zero and returns a "started" status. This is provided to allow counted completions to begin safely while holding object locks in inverted order. int completion_done(struct completion *x) returns 1 if there is no waiter, 0 if there is a waiter (i.e. a completion in progress). This replaces the use of semaphores for providing this exclusion and completion mechanism.

But it turned out that the latest kernel does not boot because the machine crashes early in the setup code. After some debugging it turned out that the problem is the query_ist() function. If this interrupt with that function is called the machine simply locks up. It looks like a BIOS bug. Looking for a workaround for this problem I wrote the attached patch. It checks for the CPUID instruction and if it is not implemented it does not call the speedstep BIOS function. As far as I know speedstep should be available since some Pentium earliest. Alan Cox observed that it's available since the Pentium II, so cpuid levels 4 and 5 can be excluded altogether. H. Peter Anvin cleaned up the code some more: > Right in concept, but I dislike the implementation (duplication of the > CPU detect code we already have). Could you try this patch and see if > it works for you? which, with a small modification to fix a build error with it the resulting kernel boots on my machine.

Suresh wrote: These padlock instructions though don't use/touch SSE registers, but it behaves similar to other SSE instructions. For example, it might cause DNA faults when cr0.ts is set. While this is a spurious DNA trap, it might cause oops with the recent fpu code changes. This is the code sequence that is probably causing this problem: a) new app is getting exec'd and it is somewhere in between start_thread() and flush_old_exec() in the load_xyz_binary() b) At pont "a", task's fpu state (like TS_USEDFPU, used_math() etc) is cleared. c) Now we get an interrupt/softirq which starts using these encrypt/decrypt routines in the network stack. This generates a math fault (as cr0.ts is '1') which sets TS_USEDFPU and restores the math that is in the task's xstate. d) Return to exec code path, which does start_thread() which does free_thread_xstate() and sets xstate pointer to NULL while the TS_USEDFPU is still set. e) At the next context switch from the new exec'd task to another task, we have a scenarios where TS_USEDFPU is set but xstate pointer is null. This can cause an oops during unlazy_fpu() in __switch_to() Now: 1) This should happen with or with out pre-emption. Viro also encountered similar problem with out CONFIG_PREEMPT. 2) kernel_fpu_begin() and kernel_fpu_end() will fix this problem, because kernel_fpu_begin() will manually do a clts() and won't run in to the situation of setting TS_USEDFPU in step "c" above. 3) This was working before the fpu changes, because its a spurious math fault which doesn't corrupt any fpu/sse registers and the task's math state was always in an allocated state. With out the recent lazy fpu allocation changes, while we don't see oops, there is a possible race still present in older kernels(for example, while kernel is using kernel_fpu_begin() in some optimized clear/copy page and an interrupt/softirq happens which uses these padlock instructions generating DNA fault). This is the failing scenario that existed even before the lazy fpu allocation changes: 0. CPU's TS flag is set 1. kernel using FPU in some optimized copy routine and while doing kernel_fpu_begin() takes an interrupt just before doing clts() 2. Takes an interrupt and ipsec uses padlock instruction. And we take a DNA fault as TS flag is still set. 3. We handle the DNA fault and set TS_USEDFPU and clear cr0.ts 4. We complete the padlock routine 5. Go back to step-1, which resumes clts() in kernel_fpu_begin(), finishes the optimized copy routine and does kernel_fpu_end(). At this point, we have cr0.ts again set to '1' but the task's TS_USEFPU is stilll set and not cleared. 6. Now kernel resumes its user operation. And at the next context switch, kernel sees it has do a FP save as TS_USEDFPU is still set and then will do a unlazy_fpu() in __switch_to(). unlazy_fpu() will take a DNA fault, as cr0.ts is '1' and now, because we are in __switch_to(), math_state_restore() will get confused and will restore the next task's FP state and will save it in prev tasks's FP state. Remember, in __switch_to() we are already on the stack of the next task but take a DNA fault for the prev task. This causes the fpu leakage. Fix the padlock instruction usage by calling them inside the context of new routines irq_ts_save/restore(), which clear/restore cr0.ts manually in the interrupt context. This will not generate spurious DNA in the context of the interrupt which will fix the oops encountered and the possible FPU leakage issue.

First, we're testing the wrong qdisc. We just reset the device queue qdiscs to &noop_qdisc and checking it's state is completely pointless here. We want to wait until the previous qdisc that was sitting at the ->qdisc pointer is not busy any more. And that would be ->qdisc_sleeping. Because of how we propagate the samples qdisc pointer down into qdisc_run and friends via per-cpu ->output_queue and netif_schedule, we have to wait also for the __QDISC_STATE_SCHED bit to clear as well.

under traffic Load/Unload under traffic Few issues were found when loading and unloading under traffic: - When receiving Tx interrupt call netif_wake_queue if the queue is stopped but the state is open - Check that interrupts are enabled before doing anything else on the msix_fp_int function - In nic_load, enable the interrupts only when needed and ready for it - Function stop_leading returns status since it can fail - Add 1ms delay when unloading the driver to validate that there are no open transactions that already started by the FW - Splitting the "has work" function into Tx and Rx so the same function will be used on unload and interrupts - Do not request for WoL if only resetting the device (save the time that it takes the FW to set the link after reset) - Fixing the device reset after iSCSI boot and before driver load - all internal buffers must be cleared before the driver is loaded Signed-off-by: Vladislav Zolotarov Signed-off-by: Eilon Greenstein Signed-off-by: David S.

When a network namespace is created, other than the init_net and a multicast packet is received, the kernel goes to a hang or a kernel panic.

Introduced here are trivial no-op versions of the desired accessors for current and other tasks so that other subsystems can start to be converted over more easily. Wrappers are introduced into a new header (linux/cred.h) for UID/GID, EUID/EGID, SUID/SGID, FSUID/FSGID, cap_effective and current's subscribed user_struct. These wrappers are macros because the ordering between header files mitigates against making them inline functions. linux/cred.h is #included from linux/sched.h. Further, XFS is modified such that it no longer defines and uses parameterised versions of current_fs[ug]id(), thus getting rid of the namespace collision otherwise incurred.

This driver was included into the kernel mainly to connect to the ISDN framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile and moving ISDN support, this connection was never realized, and the only use of this driver was for device configuration. In the age of DSL, the demand of ISDN support is getting very low. Meanwhile, with the advent of libusb, an userspace driver was done for the device configuration which works fine for linux and mac. (Thanks to the libusb developers!). The userspace driver is downloadable from the auerswald web site. So this driver is obsolete now and has to be removed. Many thanks to all developers which helped me to bring this driver up and working.

The patch avoids enabling RHSC interrupt requests when the RHCS status bit is already set. This should have no adverse affects on normal controllers, since they won't set the status bit until a root-hub status change actually occurs, in which case we wouldn't enable RHSC interrupt requests anyway -- we would wait until the status change had been processed and cleared.

By default all devices that do not have a Linux enabled TRU-Install device (i.e. the device does not have a Linux package on the virtual CD partition) will be switched into "modem mode." Devices that do contain a Linux package in the TRU-Install virtual CD will be allowed to enumerate as a CD-Rom so that either (a) a user can install the packaged software or (b) a user-space application (e.g. udev) can switch it to modem mode. This patch does allow for manual override by adding a usb-storage module parameter 'swi_tru_install' which can force the modem into either mode regardless of what packages it contains.

Most of the RX path work is now done in the RX tasklet, instead of just the final "push to ldisc" step. This addresses some cases of data loss: - A longstanding serial gadget bug: when tty_insert_flip_string() didn't copy the entire buffer, the rest of the characters were dropped! Now that packet stays queued until the rest of its data is pushed to the ldisc. - Another longstanding issue: in the unlikely case that an RX transfer returns data and also reports a fault, that data is no longer discarded. - In the recently added RX throttling logic: it needs to stop pushing data into the TTY layer, instead of just not submitting new USB read requests. When the TTY is throttled long enough, backpressure will eventually make the OUT endpoint NAK. Also: an #ifdef is removed (no longer necessary); and start switching to a better convention for debug messages (prefix them with tty name).

Current driver solves this by a mdelay(1) which is very heavy weighted and slow. This patch applies the workaround from the ISP1760 FAQ by using two different banks for PTD and payload data and using a common wait for them. This wait is done by an additional ISP1760 access (whose timing constraints guarantee the 90ns delay). This improves speed when reading from an USB stick from: $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 1m 15.43s user 0m 0.44s sys 0m 39.46s to $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 0m 18.53s user 0m 0.16s sys 0m 12.97s [bigeasy@linutronix.de: fixed comment formating, moved define into header file, obey 80 char rule] Signed-off-by: Enrico Scholz Signed-off-by: Sebastian Siewior Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/isp1760-hcd.c | 44 ++++++++++++++++++++++++---------- drivers/usb/host/isp1760-hcd.h | 2 ++ 2 files changed, 33 insertions(+), 13 deletions(-) diff --git a/drivers/usb/host/isp1760-hcd.c b/drivers/usb/host/isp1760-hcd.c index db5f4f5c7a10..e209b3b709d6 100644 --- a/drivers/usb/host/isp1760-hcd.c +++ b/drivers/usb/host/isp1760-hcd.c @@ -126,9 +126,8 @@ static void isp1760_writel(const unsigned int val, __u32 __iomem *regs) * doesn't quite work because some people have to enforce 32-bit access */ static void priv_read_copy(struct isp1760_hcd *priv, u32 *src, - __u32 __iomem *dst, u32 offset, u32 len) + __u32 __iomem *dst, u32 len) { - struct usb_hcd *hcd = priv_to_hcd(priv); u32 val; u8 *buff8; @@ -136,11 +135,6 @@ static void priv_read_copy(struct isp1760_hcd *priv, u32 *src, printk(KERN_ERR "ERROR: buffer: %p len: %d\n", src, len); return; } - isp1760_writel(offset, hcd->regs + HC_MEMORY_REG); - /* XXX - * 90nsec delay, the spec says something how this could be avoided. - */ - mdelay(1); while (len >= 4) { *src = __raw_readl(dst); @@ -987,8 +981,20 @@ static void do_atl_int(struct usb_hcd *usb_hcd) printk(KERN_ERR "qh is 0\n"); continue; } - priv_read_copy(priv, (u32 *)&ptd, usb_hcd->regs + atl_regs, - atl_regs, sizeof(ptd)); + isp1760_writel(atl_regs + ISP_BANK(0), usb_hcd->regs + + HC_MEMORY_REG); + isp1760_writel(payload + ISP_BANK(1), usb_hcd->regs + + HC_MEMORY_REG); + /* + * write bank1 address twice to ensure the 90ns delay (time + * between BANK0 write and the priv_read_copy() call is at + * least 3*t_WHWL + 2*t_w11 = 3*25ns + 2*17ns = 92ns) + */ + isp1760_writel(payload + ISP_BANK(1), usb_hcd->regs + + HC_MEMORY_REG); + + priv_read_copy(priv, (u32 *)&ptd, usb_hcd->regs + atl_regs + + ISP_BANK(0), sizeof(ptd)); dw1 = le32_to_cpu(ptd.dw1); dw2 = le32_to_cpu(ptd.dw2); @@ -1091,7 +1097,7 @@ static void do_atl_int(struct usb_hcd *usb_hcd) case IN_PID: priv_read_copy(priv, priv->atl_ints[queue_entry].data_buffer, - usb_hcd->regs + payload, payload, + usb_hcd->regs + payload + ISP_BANK(1), length); case OUT_PID: @@ -1206,8 +1212,20 @@ static void do_intl_int(struct usb_hcd *usb_hcd) continue; } - priv_read_copy(priv, (u32 *)&ptd, usb_hcd->regs + int_regs, - int_regs, sizeof(ptd)); + isp1760_writel(int_regs + ISP_BANK(0), usb_hcd->regs + + HC_MEMORY_REG); + isp1760_writel(payload + ISP_BANK(1), usb_hcd->regs + + HC_MEMORY_REG); + /* + * write bank1 address twice to ensure the 90ns delay (time + * between BANK0 write and the priv_read_copy() call is at + * least 3*t_WHWL + 2*t_w11 = 3*25ns + 2*17ns = 92ns) + */ + isp1760_writel(payload + ISP_BANK(1), usb_hcd->regs + + HC_MEMORY_REG); + + priv_read_copy(priv, (u32 *)&ptd, usb_hcd->regs + int_regs + + ISP_BANK(0), sizeof(ptd)); dw1 = le32_to_cpu(ptd.dw1); dw3 = le32_to_cpu(ptd.dw3); check_int_err_status(le32_to_cpu(ptd.dw4)); @@ -1242,7 +1260,7 @@ static void do_intl_int(struct usb_hcd *usb_hcd) case IN_PID: priv_read_copy(priv, priv->int_ints[queue_entry].data_buffer, - usb_hcd->regs + payload , payload, + usb_hcd->regs + payload + ISP_BANK(1), length); case OUT_PID: diff --git a/drivers/usb/host/isp1760-hcd.h b/drivers/usb/host/isp1760-hcd.h index 6473dd86993c..3c61cd51cbb8 100644 --- a/drivers/usb/host/isp1760-hcd.h +++ b/drivers/usb/host/isp1760-hcd.h @@ -54,6 +54,8 @@ void deinit_kmem_cache(void); #define BUFFER_MAP 0x7 #define HC_MEMORY_REG 0x33c +#define ISP_BANK(x) ((x) << 16) + #define HC_PORT1_CTRL 0x374 #define PORT1_POWER (3 << 3) #define PORT1_INIT1 (1 << 7) From 7839b5162d7d6c100f70a036be1e1f2b072857bc Mon Sep 17 00:00:00 2001 From: Sebastian Siewior Date: Thu, 17 Jul 2008 20:09:29 +0200 Subject: [PATCH 0407/1063] usb: isp1760: don't be noisy about short packets.

There is a timeout, so it can't wait too long. Provide missing locking inside acm_wb_is_avail(); it matters more now. Note, this presumes an earlier patch was applied, removing a call to this routine where the lock was held. Slightly improved diagnostics on write URB completion, so we can tell when a write URB gets killed and, if so, how much data it wrote first ... and so that I/O path is normally silent (and can't much change timings).

Those products integrate the Inventra logic + * with other DMA, IRQ, and bus modules, as well as other logic that + * needs to be reflected in this driver. + * + * + * NOTE: the original Mentor code here was pretty much a collection + * of mechanisms that don't seem to have been fully integrated/working + * for *any* Linux kernel version. This version aims at Linux 2.6.now, + * Key open issues include: + * + * - Lack of host-side transaction scheduling, for all transfer types. + * The hardware doesn't do it; instead, software must. + * + * This is not an issue for OTG devices that don't support external + * hubs, but for more "normal" USB hosts it's a user issue that the + * "multipoint" support doesn't scale in the expected ways. That + * includes DaVinci EVM in a common non-OTG mode. + * + * * Control and bulk use dedicated endpoints, and there's as + * yet no mechanism to either (a) reclaim the hardware when + * peripherals are NAKing, which gets complicated with bulk + * endpoints, or (b) use more than a single bulk endpoint in + * each direction. + * + * RESULT: one device may be perceived as blocking another one. + * + * * Interrupt and isochronous will dynamically allocate endpoint + * hardware, but (a) there's no record keeping for bandwidth; + * (b) in the common case that few endpoints are available, there + * is no mechanism to reuse endpoints to talk to multiple devices. + * + * RESULT: At one extreme, bandwidth can be overcommitted in + * some hardware configurations, no faults will be reported. + * At the other extreme, the bandwidth capabilities which do + * exist tend to be severely undercommitted.

Miller" Date: Thu, 14 Aug 2008 01:45:41 -0700 Subject: [PATCH 0474/1063] sparc64: Fix cmdline_memory_size handling bugs. First, lmb_enforce_memory_limit() interprets it's argument (mostly, heh) as a size limit not an address limit. So pass the raw cmdline_memory_size value into it. And we don't need to check it against zero, lmb_enforce_memory_limit() does that for us. Next, free_initmem() needs special handling when the kernel command line trims the available memory. The problem case is if the trimmed out memory is where the kernel image itself resides. When that memory is trimmed out, we don't add those physical ram areas to the sparsemem active ranges, amongst other things. Which means that this free_initmem() code will free up invalid page structs, resulting in either crashes or hangs. Just quick fix this by not freeing initmem at all if "mem=" was given on the boot command line. Signed-off-by: David S.

One in init/main.c and another in arch/x86/smpboot.c. So I nuked the one in arch/x86. Also 64-bit kernels used to handle maxcpus= as documented in Documentation/cpu-hotplug.txt. CPUs with 'id > maxcpus' are initialized but not booted. 32-bit version for some reason ignored them even though all the infrastructure for booting them later is there. In the current mainline both 64 and 32 bit versions are broken. This patch restores the correct behaviour. I've tested x86_64 version on 4- and 8- way Core2 and 2-way Opteron based machines. Various config combinations SMP, !SMP, CPU_HOTPLUG, !CPU_HOTPLUG. Booted with maxcpus=1 and maxcpus=4, etc. Everything is working as expected. So far we've received two reports from different people confirming that 32-bit version also works fine, both on dual core laptops and 16way server machines.

In Smack and commoncap, this uses has_capability() to determine whether the parent will be permitted to use PTRACE_ATTACH if normal checks fail. This does not set PF_SUPERPRIV. Two of the instances of __capable() actually only act on current, and so have been changed to calls to capable(). Of the places that were using __capable(): (1) The OOM killer calls __capable() thrice when weighing the killability of a process. All of these now use has_capability(). (2) cap_ptrace() and smack_ptrace() were using __capable() to check to see whether the parent was allowed to trace any process. As mentioned above, these have been split. For PTRACE_ATTACH and /proc, capable() is now used, and for PTRACE_TRACEME, has_capability() is used. (3) cap_safe_nice() only ever saw current, so now uses capable(). (4) smack_setprocattr() rejected accesses to tasks other than current just after calling __capable(), so the order of these two tests have been switched and capable() is used instead. (5) In smack_file_send_sigiotask(), we need to allow privileged processes to receive SIGIO on files they're manipulating. (6) In smack_task_wait(), we let a process wait for a privileged process, whether or not the process doing the waiting is privileged. I've tested this with the LTP SELinux and syscalls testscripts.

At the same time although one process is already waken up by some events, it won't be scheduled immediately. So maybe there exists the following phenomena: a. The current jiffies is already after the predefined jiffies. But before timeout happens, OS has no chance to check the EC status again. b. If preemptible schedule is enabled, maybe preempt schedule will happen before checking loop. When the process is resumed again, maybe timeout already happens, which means that OS has no chance to check the EC status. In such case maybe EC status is already what OS expects when timeout happens. But OS has no chance to check the EC status and regards it as AE_TIME. So it will be more appropriate that OS will try to check the EC status again when timeout happens. If the EC status is what we expect, it won't be regarded as timeout. Only when the EC status is not what we expect, it will be regarded as timeout, which means that EC controller can't give a response in time. http://bugzilla.kernel.org/show_bug.cgi?id=9823 http://bugzilla.kernel.org/show_bug.cgi?id=11141 Signed-off-by: Zhao Yakui Signed-off-by: Zhang Rui Signed-off-by: Andi Kleen --- drivers/acpi/ec.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/acpi/ec.c b/drivers/acpi/ec.c index 76784ae7e6a1..13593f9f2197 100644 --- a/drivers/acpi/ec.c +++ b/drivers/acpi/ec.c @@ -221,6 +221,8 @@ static int acpi_ec_wait(struct acpi_ec *ec, enum ec_event event, int force_poll) return 0; msleep(1); } + if (acpi_ec_check_status(ec,event)) + return 0; } pr_err(PREFIX "acpi_ec_wait timeout, status = 0x%2.2x, event = %s\n", acpi_ec_read_status(ec), From fa46d3526461e8aa7c0fb39cc1b98ac656695a43 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 1 Aug 2008 15:58:17 -0600 Subject: [PATCH 0498/1063] ACPI: bounds check IRQ to prevent memory corruption acpi_penalize_isa_irq() should validate irq before using it to index the acpi_irq_penalty[] table.

Current Linux suspend code performs an assignment after the flush, which can add dirty data back to the cache.  On some AMD platforms, additional speculative reads have caused crashes on resume because of this dirty data. Relocate the cache flush to be the very last thing done before halting.  Tie into an assembly line so the compile will not reorder it.  Add some documentation explaining what is going on and why we're doing this.

I can see they're interesting to CPA developers and TLB optimizers, but they don't fit its usual "where has all my memory gone?" usage. If they are to stay, here are some fixes. 1. On x86_32 without PAE, they're not 2M but 4M pages: no need to mess with the internal enum, but show the right name to users. 2. Many machines can never show anything but 0 for DirectMap1G, so suppress that line unless direct_gbpages are really enabled. 3. The unit in /proc/meminfo is kB not number of pages: HugePages messed that up, but they're an example to regret not to follow. 4. Once we use kB, it's easy to see that 1GB has gone missing (which explains why CONFIG_CPA_DEBUG=y soon wraps DirectMap2M negative): because head_64.S's level2_ident_pgt entries were not counted. My fix is not ideal, but works for more and for less than 1G, and avoids interfering with early bootup pagetable contortions.

However, since the manual probing method is brittle and prone to failure on some Abit motherboards (esp. the Abit IP35 Pro) it is better to use DMI to also read the board name and then decide whether or not to probe the bus. At the moment, we do not have a list of valid DMI name strings to use for existing and supported motherboards. This patch only implements DMI probing for the IP35 Pro. For motherboards that can not yet use DMI probing, a warning will be printed to the kernel log asking those users to email me their dmidecode output. The existing manual probing mechanism will be used if CONFIG_DMI is not enabled, if DMI probing fails (for DMI-unsupported motherboards), or if DMI probing fails and the "force" option is set (for DMI-supported motherboards). Ideally in the longer term this manual probing method would be removed. This patch should be safe to apply as it does not change the probing behaviour for most of the supported motherboards, just the IP35 Pro, which already has regressions filed against it in 2.6.26.

On the x3650 M2 and (presumably) later, we are returned a value indicating success and a buffer full of garbage or zeroes. This causes the probe function to run in an infinite loop. To fix this, we add one last check--if the interface number we're looking for is higher than the number of interfaces that AEM claims to have, stop probing. Signed-off-by: Darrick J.

The SPI master driver is told to set the device up before adding it to the driver model, so that it's always properly set up when probe() is called. (This is important, because in the case of inverted chipselects, this device can make the bus misbehave until it's properly deselected. It's got to be set up even if no driver binds to the device.) The trouble spot is that it doesn't first verify that no other device has been added using that chipselect. If such a device has been added, its configuration gets trashed. (Fortunately this has not been a common error!) The fix here adds an explicit check, and a mutex to protect the relevant critical region.

This is often because set_pte_vaddr_pud lacks a __init annotation or the annotation of spp_getpage is wrong. spp_getpage is called from __init (__init_extra_mapping) and non __init (set_pte_vaddr_pud) functions, so it can't be __init.

The use of MAP_32BIT is a legacy hack - to speed up context switching on certain early model 64-bit P4 CPUs. So introduce a new flag to be used by glibc instead, to not constrain 64-bit apps like this. glibc can switch to this new flag straight away - it will be ignored by the kernel. If those old CPUs ever matter to anyone, support for it can be implemented.

The use of MAP_32BIT is a legacy hack - to speed up context switching on certain early model 64-bit P4 CPUs. So introduce a new flag to be used by glibc instead, to not constrain 64-bit apps like this. glibc can switch to this new flag straight away - it will be ignored by the kernel. If those old CPUs ever matter to anyone, support for it can be implemented.

This patch lets the user disable the rebuild if the interval is set to zero. This also incidentally fixes a divide-by-zero error with name-spaces.

Unfortunately that patch contained a bug that cause the driver to wait 2.5 seconds, rather than 2.5 milliseconds as intended. This patch fixes that bug. This bug revealed that not all firmware versions service driver events though. Since we do not know which versions of the firmware do and don't service these events, the driver needs some way to minimize the effects of the delay. This patch solves the problem by recording a jiffies timestamp when it submits an event to the hardware.

When gathering information for a get_ethtool_stats call, the driver will call a driver-private, inlined get_stat64() function, which returns an unsigned long value. This call will inadvertently mask off the upper 32-bits of a stat on 32-bit machines. This patch defines a new get_estat() inline function and modifies the ESTAT_ADD() macro to use it.

But that made performance drop from 8.4 seconds to 8.8 seconds on 1G lguest->Host TCP xmit. So now we only do that as a fallback.

Current inline asm constraint used in the implementation of prefetch() makes gcc believe that the pointer is dereferenced even though the PLD instruction does not load any data and does not cause a segmentation fault on null pointers, which causes all sorts of interesting results when reaching the end of a linked lists for example. Let's use a better constraint to properly represent the actual usage of the pointer value. Problem reported by Chris Steel.

Greg Wettstein (greg@enjellic.com) noted: http://article.gmane.org/gmane.linux.scsi/43409 on a reboot of a previously recognized SCST target, the initiator driver would be unable to re-recognize the device as a target. It turns out that prior to the SCST software reloading and returning it's "target-capable" abilities in the PRLI payload, the HBA would be re-initialized as an initiator-only type port. Since initiators typically classify themselves as an FCP-2 capable device, both software and firmware do not perform an explicit logout during port-loss. Unfortunately, as can be seen by the failure case, when the port (now target-capable) returns, firmware performs an ADISC without a follow-on PRLI, leaving stale 'initiator-only' data in the firmware's port database. Correct the discrepancy by performing the explicit logout during the transport's request to terminate-rport-io, thus synchronizing port states and ensuring a follow-on PRLI is performed.

This should also address a problem reported by Gal Rosen (http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the driver would attempt to awaken a previously torn-down DPC thread from interrupt context by implicitly calling wake_up_process() rather than the driver's qla2xxx_wake_dpc() helper. Rather, than reshuffle the remove_one() device-removal code, during unload, depend on the driver's timer to wake-up the DPC process, by limiting wake-ups based on an 'unloading' flag.

Fix it by removing the unnecessary '#define __user' from the file.

This isn't perfect yet, but subsequent changesets will make it so. This part is just one piece of the puzzle. Signed-off-by: David S.

Intel's add/sub documentation specifies they have to be passed as registers.

The removal of the links inside the Bluetooth class broke assumptions by userspace programs on how to find attached adapters. This patch creates adapters and connections as part of the Bluetooth class, but it uses different device types to distinguish them. The userspace programs can now easily navigate in the sysfs device tree. The unused platform device and bus have been removed to keep the code simple and clean.

Consolidate them into two entries. One for Bluetooth drivers and another one for the Bluetooth subsystem. Also the MODULE_AUTHOR should indicate the current maintainer of the module and actually not the original author. Fix all Bluetooth modules to provide current maintainer information.

Otherwise we either end up with 16 bytes less on every requeue, or if a new frame is worthy enough to be accepted, the data is in the wrong place (urb->transfer_buffer wasn't updated!) and mac80211 has a hard time to recognize it...

It extends commit af744e3294d09d706c4eae26cffaaa68a8d40337 ("cdrom: don't check CDC_PLAY_AUDIO in cdrom_count_tracks()") with a safety check and non-audio ioctls support. Since CDC_PLAY_AUDIO flag was used not only to check ability to play audio but also to ensure that audio_ioctl was not NULL, all TOC-related operations had to use it.

This includes freeing the Request-skb ( in dccp_rcv_request_sent_state_process() ). As a consequence, * the arrival of further packets cause a double-free, triggering a panic(), * the connection then may hang, since further retransmissions are blocked. This patch changes the order of statements so that the retransmission timer is reset, and the pending Request freed, only if a valid Response has arrived (or the number of sysctl-retries has been exhausted). Further changes: ---------------- To be on the safe side, replaced __kfree_skb with kfree_skb so that if due to unexpected circumstances the sk_send_head is NULL the WARN_ON is used instead.

This happens because nf_nat_setup_info() - via nf_conntrack_alter_reply() - sets the helper before ctnetlink, which indeed does not check if the conntrack already has a helper as it thinks that it is a brand new conntrack. The fix moves the helper assignation before the set of the status flags.

If dev_deactivate() is trying to quiesce the queue, it is theoretically possible for another cpu to livelock trying to process that queue. This happens because dev_deactivate() grabs the queue spinlock as it checks the queue state, whereas net_tx_action() does a trylock and reschedules the qdisc if it hits the lock. This breaks the livelock by adding a check on __QDISC_STATE_DEACTIVATED to net_tx_action() when the trylock fails. Based upon feedback from Herbert Xu and Jarek Poplawski. Signed-off-by: David S.

(Logged as "Failed to reconnect to sbp2 device!".) The core would then unbind sbp2 from the device. This is not justified if the .update() failed because another bus reset happened. We check this and tell the ieee1394 that .update() succeeded, and the core will call sbp2's .update() for the new bus reset as well. This improves reconnection/re-login especially on buses with several disks as they may issue bus resets in close succession when they come online. Tested by Damien Benoist.

However, ipoib_stop() (which is run inside rtnl_lock()) flushes this workqueue, which leads to a deadlock if the join task is pending. Fix this by simply not flushing the workqueue from ipoib_stop(). It turns out that we really don't care about workqueue tasks running during or after ipoib_stop(), as long as we make sure to flush the workqueue before unregistering a netdev. This fixes .

The lock_super() there had been just an automatic conversion of the kernel lock to the superblock lock, but no locking was actually needed there, since the code in fat_write_inode already protected all relevant accesses with a spinlock (sbi->inode_hash_lock to be exact). The only code inside the BKL (and thus the superblock lock) was accesses tp local variables or calls to functions that have long been SMP-safe (i.e. sb_bread, mark_buffe_dirty and brlese).

Andreas Herrmann spotted this flaw when a bootmem allocation on an unaligned node was itself not aligned because the combination of an unaligned node with an aligned offset into that node is not garuanteed to be aligned itself. This patch introduces two helper functions that align a node-relative index or offset with respect to the node's starting address so that the absolute PFN or virtual address that results from combining the two satisfies the requested alignment. Then all the broken ALIGN()s in alloc_bootmem_core() are replaced by these helpers.

It uses page_check_address to find the pte. That function has a shortcut to avoid the ptl if the pte is not present. Unfortunately, the pte can be switched to not-present then back to present by other code while holding the page table lock -- this should not be a signal for page_mkclean to ignore that pte, because it may be dirty. For example, powerpc64's set_pte_at will clear a previously present pte before setting it to the desired value. There may also be other code in core mm or in arch which do similar things. The consequence of the bug is loss of data integrity due to msync, and loss of dirty page accounting accuracy. XIP's __xip_unmap could easily also be unreliable (depending on the exact XIP locking scheme), which can lead to data corruption. Fix this by having an option to always take ptl to check the pte in page_check_address. It's possible to retain this optimization for page_referenced and try_to_unmap.

This usually maps down to get_block, which expects the page lock to prevent such a situation. This causes ext2 to explode for one reason or another. Serialise those calls for the moment. For common usages today, I suspect get_xip_mem rarely is called to create new blocks. In future as XIP technologies evolve we might need to look at which operations require scalability, and rework the locking to suit.

We prevent this checking aliveness before scheduling the timer. Since during deactivation the root qdisc is available only as qdisc_sleeping additional accessor qdisc_root_sleeping() is created.

The new dev->power.status field should be initialized regardless of whether CONFIG_PM_SLEEP is enabled, and similarly dpm_sysfs_add() should be called whenever CONFIG_PM is enabled. The patch separates out the call to dpm_sysfs_add() from the call to device_pm_add(). As a result device_pm_add() can no longer return an error, so its return type is changed to void.

This driver is very similar to the regular UIO platform driver, but is only suitable for devices that are connected to the interrupt controller using unique interrupt lines. The uio_pdrv_genirq driver includes generic interrupt handling code which disables the serviced interrupt in the interrupt controller and makes the user space driver responsible for acknowledging the interrupt in the device and reenabling the interrupt in the interrupt controller. Shared interrupts are not supported since the in-kernel interrupt handler will disable the interrupt line in the interrupt controller, and in a shared interrupt configuration this will stop other devices from delivering interrupts.

When control returns to this ep0_rxstate, the index register contents are over-written. This causes the CSR register write to fail. Fixed by writing the correct value into the index register before writing to the CSR. This was observed only in ep0_rxstate() with g_ether loaded and the device connected to a MS Windows host PC. Anticipatively fixed ep0_txstate() as well.

The patch fixes this problem (and the related problem that installing altsetting 0 will fail if the device is suspended) by deferring the Set-Interface call until some later time when it is legal and can succeed. Possible later times are: when a new driver is being probed for the interface, and when the interface is being resumed.

A minor improvement is that the callbacks are present only in the "USB-device" device_type structure, rather than in the bus_type structure. This way they will be invoked only for USB devices, not for USB interfaces. The core USB PM routines automatically handle suspending and resuming interfaces along with their devices.

We are not allowed to call drivers' probe routines during a system sleep transition between the "prepare" and "complete" callbacks, but that's exactly what we do when a driver doesn't have full suspend/resume support. Such drivers are unbound during the "suspend" call and reprobed during the "resume" call. The patch causes the reprobe step to be skipped if the "complete" callback hasn't been issued yet, i.e., if the interface's dev.power.status field is not equal to DPM_ON. Thus during the "resume" callback nothing bad will happen, and during the final "complete" callback the reprobing will occur as desired. This fixes the problem reported in Bugzilla #11263.

Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

Fortunately this function is only used by ext4. The function uses ffs which does not work analog to ffz. The result of ffs has an offset of 1 which is not taken into account. To fix this use the low level __ffs_word function directly instead of the ill defined ffs. In addition the patch improves find_next_zero_bit and ext2_find_next_zero_bit by passing the bit offset into __ffz_word instead of adding it after the function call returned.

Commit 3800345f723fd130d50434d4717b99d4a9f383c8 (pciehp: fix slot name) introduces the pciehp_slot_with_bus module parameter, which was intended to help work around broken firmware that assigns the same name to multiple slots. Commit 9e4f2e8d4ddb04ad16a3828cd9a369a5a5287009 (pciehp: add message about pciehp_slot_with_bus option) tells the user to use the above parameter in the event of a name collision. This approach is sub-optimal because it requires too much work from the user. Instead, let's rename the slot on behalf of the user. If firmware assigns the name N to multiple slots, then: The first registered slot is assigned N The second registered slot is assigned N-1 The third registered slot is assigned N-2 The Mth registered slot becomes N-M In the event we overflow the slot->name parameter, we report an error to the user. This is a temporary fix until the entire PCI core can be reworked such that individual drivers no longer have to manage their own slot names.

However, some hardresets can't wait for device readiness and skipping SRST can cause timeout or other failures during revalidation. Always perform follow-up SRST if hardreset returns -EAGAIN. This makes reset paths more predictable and thus less error-prone. While at it, move hardreset error checking such that it's done right after hardreset is finished. This simplifies followup SRST condition check a bit and makes the reset path easier to modify.

However, it turned out that the controller just didn't like issuing SRST after hardreset w/o clearing SError first. Interestingly, the SRST itself succeeds but the following commands fail. If SError is cleared between hardreset and SRST, which is the default behavior now, everything works fine and SIS controllers work with PMPs happily. Remove PMP blacklisting for SIS AHCIs.

This turns out to have other consequences such as code doing >= XFER_UDMA_0 also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect set_dma_mode, although some drivers call back into their own set mode code from other points. Having been through the drivers I've added helpers for using_udma/using_mwdma dma_enabled so that people don't open code ranges that may change (eg if UDMA8 appears somewhere) Thanks to David for the initial bits [and added fix for pata_oldpiix from and signed-off-by Dave Mueller -jg] Signed-off-by: Alan Cox Signed-off-by: Jeff Garzik --- drivers/ata/libata-core.c | 4 ++-- drivers/ata/pata_acpi.c | 2 +- drivers/ata/pata_atiixp.c | 2 +- drivers/ata/pata_cs5530.c | 6 +++--- drivers/ata/pata_oldpiix.c | 2 +- drivers/ata/pata_sc1200.c | 6 +++--- include/linux/libata.h | 22 ++++++++++++++++++++++ 7 files changed, 33 insertions(+), 11 deletions(-) diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index 5f8f57a818fb..79e3a8e7a84a 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -3288,7 +3288,7 @@ int ata_do_set_mode(struct ata_link *link, struct ata_device **r_failed_dev) dev->dma_mode = ata_xfer_mask2mode(dma_mask); found = 1; - if (dev->dma_mode != 0xff) + if (ata_dma_enabled(dev)) used_dma = 1; } if (!found) @@ -3313,7 +3313,7 @@ int ata_do_set_mode(struct ata_link *link, struct ata_device **r_failed_dev) /* step 3: set host DMA timings */ ata_link_for_each_dev(dev, link) { - if (!ata_dev_enabled(dev) || dev->dma_mode == 0xff) + if (!ata_dev_enabled(dev) || !ata_dma_enabled(dev)) continue; dev->xfer_mode = dev->dma_mode; diff --git a/drivers/ata/pata_acpi.c b/drivers/ata/pata_acpi.c index fbe605711554..eb919c16a03e 100644 --- a/drivers/ata/pata_acpi.c +++ b/drivers/ata/pata_acpi.c @@ -181,7 +181,7 @@ static unsigned int pacpi_qc_issue(struct ata_queued_cmd *qc) if (adev != acpi->last) { pacpi_set_piomode(ap, adev); - if (adev->dma_mode) + if (ata_dma_enabled(adev)) pacpi_set_dmamode(ap, adev); acpi->last = adev; } diff --git a/drivers/ata/pata_atiixp.c b/drivers/ata/pata_atiixp.c index d7de7baf58a8..e8a0d99d7356 100644 --- a/drivers/ata/pata_atiixp.c +++ b/drivers/ata/pata_atiixp.c @@ -183,7 +183,7 @@ static void atiixp_bmdma_start(struct ata_queued_cmd *qc) u16 tmp16; pci_read_config_word(pdev, ATIIXP_IDE_UDMA_CONTROL, &tmp16); - if (adev->dma_mode >= XFER_UDMA_0) + if (ata_using_udma(adev)) tmp16 |= (1 << dn); else tmp16 &= ~(1 << dn); diff --git a/drivers/ata/pata_cs5530.c b/drivers/ata/pata_cs5530.c index 744beebaaf49..0c4b271a9d5a 100644 --- a/drivers/ata/pata_cs5530.c +++ b/drivers/ata/pata_cs5530.c @@ -149,10 +149,10 @@ static unsigned int cs5530_qc_issue(struct ata_queued_cmd *qc) struct ata_device *prev = ap->private_data; /* See if the DMA settings could be wrong */ - if (adev->dma_mode != 0 && adev != prev && prev != NULL) { + if (ata_dma_enabled(adev) && adev != prev && prev != NULL) { /* Maybe, but do the channels match MWDMA/UDMA ? */ - if ((adev->dma_mode >= XFER_UDMA_0 && prev->dma_mode < XFER_UDMA_0) || - (adev->dma_mode < XFER_UDMA_0 && prev->dma_mode >= XFER_UDMA_0)) + if ((ata_using_udma(adev) && !ata_using_udma(prev)) || + (ata_using_udma(prev) && !ata_using_udma(adev))) /* Switch the mode bits */ cs5530_set_dmamode(ap, adev); } diff --git a/drivers/ata/pata_oldpiix.c b/drivers/ata/pata_oldpiix.c index e678af383d13..df64f2443001 100644 --- a/drivers/ata/pata_oldpiix.c +++ b/drivers/ata/pata_oldpiix.c @@ -198,7 +198,7 @@ static unsigned int oldpiix_qc_issue(struct ata_queued_cmd *qc) if (adev != ap->private_data) { oldpiix_set_piomode(ap, adev); - if (adev->dma_mode) + if (ata_dma_enabled(adev)) oldpiix_set_dmamode(ap, adev); } return ata_sff_qc_issue(qc); diff --git a/drivers/ata/pata_sc1200.c b/drivers/ata/pata_sc1200.c index cbab397e3db7..0278fd2b8fb1 100644 --- a/drivers/ata/pata_sc1200.c +++ b/drivers/ata/pata_sc1200.c @@ -167,10 +167,10 @@ static unsigned int sc1200_qc_issue(struct ata_queued_cmd *qc) struct ata_device *prev = ap->private_data; /* See if the DMA settings could be wrong */ - if (adev->dma_mode != 0 && adev != prev && prev != NULL) { + if (ata_dma_enabled(adev) && adev != prev && prev != NULL) { /* Maybe, but do the channels match MWDMA/UDMA ? */ - if ((adev->dma_mode >= XFER_UDMA_0 && prev->dma_mode < XFER_UDMA_0) || - (adev->dma_mode < XFER_UDMA_0 && prev->dma_mode >= XFER_UDMA_0)) + if ((ata_using_udma(adev) && !ata_using_udma(prev)) || + (ata_using_udma(prev) && !ata_using_udma(adev))) /* Switch the mode bits */ sc1200_set_dmamode(ap, adev); } diff --git a/include/linux/libata.h b/include/linux/libata.h index 80233fdc159f..225bfc5bd9ec 100644 --- a/include/linux/libata.h +++ b/include/linux/libata.h @@ -1429,6 +1429,28 @@ static inline unsigned long ata_deadline(unsigned long from_jiffies, return from_jiffies + msecs_to_jiffies(timeout_msecs); } +/* Don't open code these in drivers as there are traps.

The context memory of the request is used by both operations. The problem is that when an asynchronous encryption completes, we will compute the ICV and then reread the context memory of the encryption to get the original request. It just happens that we have a buffer of 16 bytes in front of the request pointer, so ICVs of 16 bytes (such as SHA1) do not trigger the bug. However, any attempt to uses a larger ICV instantly kills the machine when the first asynchronous encryption is completed. This patch fixes this by saving the request pointer before we start the ICV computation.

With IPV6 when an address is added to an interface, Zebra creates a duplicate RIB entry, one as a connected route, and other as a kernel route. When an address is added to an interface the RTN_NEWADDR message causes Zebra to create a connected route. In IPV4 when an address is added to an interface a RTN_NEWROUTE message is set to user space with the protocol RTPROT_KERNEL. Zebra ignores these messages, because it already has the connected route. The problem is that route created in IPV6 has route protocol == RTPROT_BOOT. Was this a design decision or a bug? This fixes it. Same patch applies to both net-2.6 and stable.

Wysocki" Date: Fri, 22 Aug 2008 22:23:09 +0200 Subject: [PATCH 0860/1063] x86 MCE: Fix CPU hotplug problem with multiple multicore AMD CPUs During CPU hot-remove the sysfs directory created by threshold_create_bank(), defined in arch/x86/kernel/cpu/mcheck/mce_amd_64.c, has to be removed before its parent directory, created by mce_create_device(), defined in arch/x86/kernel/cpu/mcheck/mce_64.c . Moreover, when the CPU in question is hotplugged again, obviously the latter has to be created before the former. At present, the right ordering is not enforced, because all of these operations are carried out by CPU hotplug notifiers which are not appropriately ordered with respect to each other. This leads to serious problems on systems with two or more multicore AMD CPUs, among other things during suspend and hibernation. Fix the problem by placing threshold bank CPU hotplug callbacks in mce_cpu_callback(), so that they are invoked at the right places, if defined. Additionally, use kobject_del() to remove the sysfs directory associated with the kobject created by kobject_create_and_add() in threshold_create_bank(), to prevent the kernel from crashing during CPU hotplug operations on systems with two or more multicore AMD CPUs.

This can lead to a situation where the receive out-of-memory timer is pending because a previous rxq_refill() didn't manage to refill the receive ring entirely as a result of being out of memory, and rxq_refill() is then called again as a side effect of a packet receive interrupt, and that rxq_refill() call then again does not succeed to refill the entire receive ring with fresh empty skbuffs because we are still out of memory, and then tries to call add_timer() on the already scheduled out-of-memory timer. This patch fixes this issue by changing the add_timer() call in rxq_refill() to a mod_timer() call. If the OOM timer was not already scheduled, this will behave as before, whereas if it was already scheduled, this patch will push back its firing time a bit, which is safe because we've (unsuccessfully) attempted to refill the receive ring just before we do this.

But a descriptor in the receive ring not being owned by the hardware can also happen when we are low on memory and did not manage to refill the receive ring fully.

Fix this by rounding the size of allocated receive buffers up to a multiple of eight bytes. While we are at it, add a bit of extra space to each receive buffer so that we can handle multiple vlan tags on ingress.

However, the quirks happen real early before "interface" is per se initialized from NULL. The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the end, when "interface" has it's final value.

Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.

If e820 reserved entries happen to be registered first in the resource tree [which v2.6.26 started doing], then the PCI code will reallocate that device's BAR to some other address - breaking timer IRQs and hanging the system. ( Normally hpet devices are hidden by the BIOS from the OS's PCI discovery via chipset magic. Sometimes the hpet is not a PCI device at all. ) Solve this fundamental fragility by making non-PCI platform drivers insert resources into the resource tree even if it overlaps the e820 reserved entry, to keep the resource manager from updating the BAR. Also do these checks for the ioapic and mmconfig addresses, and emit a warning if this happens.

Instead it is freed in the i2c device probe function's error path. However the success or failure of both functions is not linked, so this could result in a double free (if the platform device is successfully probed, the i2c device probing fails and then the platform driver is unregistered.) * codec->private_data is allocated in many platform device probe functions but not freed in their error paths. This patch hopefully solves all these problems.

The .text.fixup section is not mentioned on vmlinux.lds, and is included on the resulting vmlinux (just after .text) only because of ld heuristics on placing orphan sections. However, placing .text.fixup outside .text breaks the definition of _etext, making it exclude the .text.fixup contents. That makes .text.fixup be ignored by the kernel initialization code that needs to know about section locations, such as the code setting page protection bits.

Therefore relying on it to calculate a window to clip whacky TSC values doesn't work as it can drift around. So instead use [GTOD, GTOD+TICK_NSEC) as the window. b) __update_sched_clock() did (roughly speaking): delta = sched_clock() - scd->tick_raw; clock += delta; Which gives exponential growth, instead of linear. c) allows the sched_clock_cpu() value to warp the u64 without breaking. the results are more reliable sched_clock() deltas: before after sched_clock cpu_clock: 15750 51312 51488 cpu_clock: 59719 51052 50947 cpu_clock: 15879 51249 51061 cpu_clock: 1 50933 51198 cpu_clock: 1 50931 51039 cpu_clock: 1 51093 50981 cpu_clock: 1 51043 51040 cpu_clock: 1 50959 50938 cpu_clock: 1 50981 51011 cpu_clock: 1 51364 51212 cpu_clock: 1 51219 51273 cpu_clock: 1 51389 51048 cpu_clock: 1 51285 51611 cpu_clock: 1 50964 51137 cpu_clock: 1 50973 50968 cpu_clock: 1 50967 50972 cpu_clock: 1 58910 58485 cpu_clock: 1 51082 51025 cpu_clock: 1 50957 50958 cpu_clock: 1 50958 50957 cpu_clock: 1006128 51128 50971 cpu_clock: 1 51107 51155 cpu_clock: 1 51371 51081 cpu_clock: 1 51104 51365 cpu_clock: 1 51363 51309 cpu_clock: 1 51107 51160 cpu_clock: 1 51139 51100 cpu_clock: 1 51216 51136 cpu_clock: 1 51207 51215 cpu_clock: 1 51087 51263 cpu_clock: 1 51249 51177 cpu_clock: 1 51519 51412 cpu_clock: 1 51416 51255 cpu_clock: 1 51591 51594 cpu_clock: 1 50966 51374 cpu_clock: 1 50966 50966 cpu_clock: 1 51291 50948 cpu_clock: 1 50973 50867 cpu_clock: 1 50970 50970 cpu_clock: 998306 50970 50971 cpu_clock: 1 50971 50970 cpu_clock: 1 50970 50970 cpu_clock: 1 50971 50971 cpu_clock: 1 50970 50970 cpu_clock: 1 51351 50970 cpu_clock: 1 50970 51352 cpu_clock: 1 50971 50970 cpu_clock: 1 50970 50970 cpu_clock: 1 51321 50971 cpu_clock: 1 50974 51324 Signed-off-by: Peter Zijlstra Signed-off-by: Ingo Molnar --- kernel/sched_clock.c | 84 ++++++++++++++++++-------------------------- 1 file changed, 34 insertions(+), 50 deletions(-) diff --git a/kernel/sched_clock.c b/kernel/sched_clock.c index 204991a0bfa7..e8ab096ddfe3 100644 --- a/kernel/sched_clock.c +++ b/kernel/sched_clock.c @@ -12,19 +12,17 @@ * * Create a semi stable clock from a mixture of other events, including: * - gtod - * - jiffies * - sched_clock() * - explicit idle events * * We use gtod as base and the unstable clock deltas.

But gcc will do it, simply because there is only one call-site. As a result, all the stack space that is allocated for all the work to load the module will still be active when we actually call the module init sequence, and the deep call chain makes stack overflows happen. And stack overflows are really hard to debug, because they not only corrupt random pages below the stack, but also corrupt the thread_info structure that is allocated under the stack. In this case, Alan Brunelle reported some crazy oopses at bootup, after loading the processor module that ends up doing complex ACPI stuff and has quite a deep callchain.

Allowing 4k CPU's is not practical at this time, because we still have a number of places that have several 'cpumask_t's on the stack, and a 4k-bit cpumask is 512 bytes of stack-space for each such variable. This literally caused functions like 'smp_call_function_mask' to have a 2.5kB stack frame, and several functions to have 2kB stackframes. With an 8kB stack total, smashing the stack was simply much too likely. At least bugzilla entry http://bugzilla.kernel.org/show_bug.cgi?id=11342 was due to this. The earlier commit to not inline load_module() into sys_init_module() fixed the particular symptoms of this that Alan Brunelle saw in that bugzilla entry, but the huge stack waste by cpumask_t's was the more direct cause. Some day we'll have allocation helpers that allocate large CPU masks dynamically, but in the meantime we simply cannot allow cpumasks this large. Cc: Alan D.

The current PS3 hypervisor requires the spu shadow regs to be mapped with the PTE page protection bits set as read-only (PP=3). This implementation uses the low level __ioremap() to bypass the page protection settings inforced by ioremap_flags() to get the needed PTE bits set for the shadow regs. This fixes a runtime failure on the PS3 introduced by the powerpc ioremap_prot rework of commit a1f242ff460e4b50a045fa237c3c56cce9eabf83 ("powerpc ioremap_prot").

Peter Anvin" Date: Mon, 25 Aug 2008 22:39:15 -0700 Subject: [PATCH 0936/1063] x86: msr: fix bogus return values from rdmsr_safe/wrmsr_safe Impact: bogus error codes (+other?) on x86-64 The rdmsr_safe/wrmsr_safe routines have macros for the handling of the edx:eax arguments. Those macros take a variable number of assembly arguments. This is rather inherently incompatible with using %digit-style escapes in the inline assembly; replace those with %[name]-style escapes. This fixes miscompilation on x86-64, which at the very least caused bogus return values. It is possible that this could also corrupt the return value; I am not sure. Signed-off-by: H.

This can easily hit the 256 byte limit (IW_CUSTOM_MAX) with APs that include number of vendor IEs in AssocResp. This results in the event message not being sent and dmesg showing "wlan0 (WE) : Wireless Event too big (366)" type of errors. Convert mac80211 to use IWEVASSOCREQIE/IWEVASSOCRESPIE to avoid the issue of being unable to send association IEs as wireless events. These newer event types use binary encoding and larger maximum size (IW_GENERIC_IE_MAX = 1024), so the likelyhood of not being able to send the IEs is much smaller than with IWEVCUSTOM. As an extra benefit, the code is also quite a bit simpler since there is no need to allocate an extra buffer for hex encoding. Signed-off-by: Jouni Malinen Signed-off-by: John W.

'If count == 8' has been used to check for the need for an extended rates tag. But count would also be equal to 8 if the for loop exited because of no more supported rates. Therefore a check for count being less than rates_len would seem more correct.

In our testing, we frequently load and unload the iwlagn driver (>50 times). Then the MAX_STACK_TRACE_ENTRIES is reached (expected behaviour?). The error message with the call trace is as below.

It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI character devices (such as st). We hit a kernel crash with them. The problem is that cmd_filter code accesses to gendisk (having struct blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only SCSI block device files. With character device files, inode->i_bdev leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter isn't safe. SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be independent on any protocols. We shouldn't change ULDs to expose their gendisk. This patch moves struct blk_scsi_cmd_filter from gendisk to request_queue, a common object, which eveyone can access to. The user interface doesn't change; users can change the filters via /sys/block/. gendisk has a pointer to request_queue so the cmd_filter code accesses to struct blk_scsi_cmd_filter.

The hypervisor does checksum offloading only on TCP packets, so ibmveth calls skb_checksum_help() for any other protocol. The bug happens because the packet is being modified after the DMA map, so we would need a memory barrier before making the hypervisor call. Reordering the code so that the DMA map happens after skb_checksum_help() has the additional advantage of fixing a DMA map leak if skb_checksum_help() where to fail.

The hardware support TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers). However, the kernel feature flags do not distinguish IPv6 with/without extension headers. Therefore, the driver needs to use NETIF_F_IP_CSUM instead of NETIF_F_HW_CSUM since the latter includes all IPv6 packets. A future patch can be created to check for extension headers and perform software checksum calculation.

However, an architecture (ARM) frees up the memmap backing memory holes on the assumption it is never used. /proc/pagetypeinfo reads the whole range of pages in a zone believing that the memmap is valid and that pfn_valid will return false if it is not. On ARM, freeing the memmap breaks the page->zone linkages even though pfn_valid() returns true and the kernel can oops shortly afterwards due to accessing a bogus struct zone *. This patch lets architectures say when FLATMEM can have holes in the memmap. Rather than an expensive check for valid memory, /proc/pagetypeinfo will confirm that the page linkages are still valid by checking page->zone is still the expected zone. The lookup of page_zone is safe as there is a limited range of memory that is accessed when calling page_zone. Even if page_zone happens to return the correct zone, the impact is that the counters in /proc/pagetypeinfo are slightly off but fragmentation monitoring is unlikely to be relevant on an embedded system.

The 2.6.28 code does not have this issue, but since the mcount recording is not going to be in 27, this must be solved for the ftrace daemon version. The resume from suspend to ram would reboot because it was triple faulting. Debugging further, I found that calling the mcount function itself was not an issue, but it would fault when it incremented preempt_count. preempt_count is on the tasks info structure that is on the low memory address of the task's stack. For some reason, it could not write to it. Resuming out of suspend to ram does quite a lot of funny tricks to get to work, so it is not surprising at all that simply doing a preempt_disable() would cause a fault. Thanks to Rafael for suggesting to add a "while (1);" to find the place in resuming that is causing the fault. I would place the loop somewhere in the code, compile and reboot and see if it would either reboot (hit the fault) or simply hang (hit the loop). Doing this over and over again, I narrowed it down that it was happening in enable_nonboot_cpus. At this point, I found that it is easier to simply disable tracing around the suspend code, instead of searching for the particular function that can not handle doing a preempt_disable. This patch disables the tracer as it suspends and reenables it on resume. I tested this patch on my Laptop, and it can resume fine with the patch. Signed-off-by: Steven Rostedt Acked-by: Rafael J.

It shrinks the stack from 1152 bytes to 192 bytes (the first version, that only did the e1000_option part, got it down to 600 bytes). About half comes from not using multiple "e1000_option" structures, the other half comes from turning the "e1000_opt_list[]" arrays into "static const" instead, so that gcc doesn't copy them onto the stack.

The sequence is: - A real-time task is running when the timer sets the rt runqueue to throttled, and the rt task is resched_task()ed and switched out, and idle is switched in since there are no non-rt tasks to run on that cpu. - Eventually the do_sched_rt_period_timer() runs and un-throttles the rt runqueue, but we just exit the timer interrupt and go back to executing the idle task in the idle loop forever. If we change the sched_rt_rq_enqueue() routine to use some of the code from the CONFIG_RT_GROUP_SCHED enabled version of this same routine and resched_task() the currently executing task (idle in our case) if it is a lower priority task than the higher rt task in the now un-throttled runqueue, the problem is no longer observed.

While this is arguably not an error on blackfin where sizeof(int) == sizeof(long), the patch is still justified on the grounds of principle. The patch was generated using the Coccinelle semantic patch framework.

The AK4396 needs the master clock to do SPI writes, so writing to an AK4396 control register directly after a sample rate change will garble the value. In our case, this leads to the DACs being misconfigured to I2S sample format, which results in a wrong output level and horrible distortions on samples louder than -6 dB. To fix this, we need to wait until the new master clock signal has become stable before doing SPI writes.

It wasn't really right to begin with (there's a better fix for the problem with e820 reservations clashing with PCI BAR's pending), but it also actually causes more regressions, so it should be reverted even before the better fix is finalized.
