This broke action mask clearing on SENSE_VALID case causing revalidation and EH complete message on successful ATAPI CC. This patch removes two local variables - action and failed_dev - which cache ehc->i.action and ehc->i.dev respectively, and make the function directly modify ehc->i.* fields to remove aliasing issues.

This fixes it by always using a u64 which is what is returned by the OF parsing routines. It also makes translation failure harmless for ISA serial ports.

For one, the way to program the RPM fans speeds into the FCU is different between it and the desktop models, which I didn't figure out until recently, and it was missing a control loop for the slots fan, running it too fast. Both of those problems were causing the machine to be much more noisy than necessary. This patch also changes the fixed value of the slots fan for desktop G5s to 40% instead of 50%. It seems to still have a pretty good airflow that way and is much less noisy.

And if a command completes then we get the status for the abort, we do not need to call into the LLD to cleanup the resources. Doing this causes and oops in iser because it ends up freeing some resources twice.

With patch, the driver access PCIconfiguration space with dedicated offset to read a signature. If the signature read, it means that the controller has capability to handle 64-bit DMA. Without this patch, the driver used to blindly claim 64-bit DMA capability. The issue has been reported by Vasily Averin [vvs@sw.ru]. Thank you Vasily for the reporting.

Oprofile calls profile_pc from NMIs even when user_mode(regs) is not true and the program counter is inside the kernel lock section. This opens a race - when a user program jumps to a kernel lock address and a NMI happens before the illegal page fault exception is raised and the program has a unmapped esp or ebp then the kernel could oops. NMIs have a higher priority than exceptions so that could happen. Add user_mode checks to i386/x86-64 profile_pc to prevent that.

I don't think it's a security issue because the values come from the fixed stack frame which should be near always user registers from a previous interrupt. Still better fix it. Longer term the register save macros need to be cleaned up to avoid such mistakes in the future. Original analysis from Richard Brunner, fix by me.

Current DEBUG_STACK size is 4K, when int1/int3 trap happens, kernel will minus current DEBUG_STACK IST value by 4k. But if int3/int1 trap is nested, it will destroy other vector's IST stack. This patch modifies this, it sets DEBUG_STACK size as 8K and allows two level of nested int1/int3 trap. Kprobe DEBUG_STACK may be nested, because kprobe handler may be probed by other kprobes. Thanks jbeulich for pointing out error in the first patch. [AK: nested kprobes are pretty dubious. Hopefully one nest will be enough.

This currently often happens with __down. Should fix this by adding proper dwarf2 annotation to all inline assembly. However until that's done we need a quick fix for 2.6.18 to avoid incomplete backtraces. So when this happens dump the rest of the stack with the old unwinder instead of silently not dumping it. There was already a optional "both" mode that dumped both, but that was too ugly. I also clarified the headers for the different backtraces a bit. Also add a clear error message for missing dwarf2 annotation that people can work on. And I removed a dead variable left over from Ingo's changes.

For this to work the kernel has to know whether a futex is a PI or a non-PI one, because the semantics are different. Since the space in relevant glibc data structures is extremely scarce, the best solution is to encode the 'PI' information in bit 0 of the robust list pointer. Existing (non-PI) glibc robust futexes have this bit always zero, so the ABI is kept. New glibc with PI-robust-futexes will set this bit.

Unfortunately, since DISEQC operations do not use the frontend thread, this meant that DISEQC could be called against an uninitalised frontend, leading to all sorts of trouble. Patch fixes this by reinstating the original fronted intialisation call.

The code that does this is currently in the wrong place, causing random bytes to be written to the tuner over i2c in the set_type function. This patch moves this code from set_type to default_set_tv_freq.

See Redhat bugzilla number 198498, found by Konrad Rzeszutek (konradr@redhat.com). There are many issues that had to be resolved to fix this problem. Firstly when I originally wrote the code to handle NUMA systems, I had a large misunderstanding that was not corrected until now. That was that I thought the "number of nodes online" referred to number of physical systems connected. So that if NUMA was disabled, there would only be 1 node and it would only show that node's PCI bus. In reality if NUMA is disabled, the system displays all of the connected chassis as one node but is only ignorant of the delays in accessing main memory. Therefore, references to num_online_nodes() and MAX_NUMNODES are incorrect and need to be set to the maximum number of nodes that can be accessed (which are 8). I created a variable, MAX_NUM_CHASSIS, and set it to 8 to fix this. Secondly, when walking the PCI in detect_calgary, the code only checked the first "slot" when looking to see if a device is present. This will work for most cases, but unfortunately it isn't always the case. In the NUMA MXE drawers, there are USB devices present on the 3rd slot (with slot 1 being empty). So, to work around this, all slots (up to 8) are scanned to see if there are any devices present. Lastly, the bus is being enumerated on large systems in a different way the we originally thought. This throws the ugly logic we had out the window. To more elegantly handle this, I reorganized the kva array to be sparse (which removed the need to have any bus number to kva slot logic in tce.c) and created a secondary space array to contain the bus number to phb mapping. With these changes Calgary boots on an x460 with 4 nodes with and without NUMA enabled.

This affects the fields that follow "timestamp" as they will be be off by 8 bytes. This is a problem for 32-bit userspace programs running with 64-bit kernels on ppc64, s390, x86-64.. any "biarch" system. Matt had submitted a different solution to lkml as an RFC earlier. We have since switched to a solution recommended by Evgeniy Polyakov. This patch fixes the problem by changing the timestamp to be a __u64, which stores the number of nanoseconds. Tested on a x86_64 system with both 32 bit application and 64 bit application and on a i386 system.

For shared IRQs, the IRQ must be enabled so long as at least one driver needs it active. Likewise, IRQs need the same support to track whether the IRQ should be enabled or disabled as a "wakeup event" source after a series of calls to {en,dis}able_irq_wake(). For shared IRQs, the IRQ must be enabled as a wakeup source during sleep so long as at least one driver needs it. But right now they _don't have_ that refcounting ... which means sharing a wakeup-capable IRQ can't work correctly in some configurations. This patch adds the refcount and flag mechanisms to set_irq_wake() -- which is what {en,dis}able_irq_wake() call -- and minimal documentation of what the irq wake mechanism does. Drivers relying on the older (broken) "toggle" semantics will trigger a warning; that'll be a handful of drivers on ARM systems.

A recent commit (7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1) moved the call to nfsd_setuser out of the 'find a dentry for a filehandle' branch of fh_verify so that it would always be called. This had the unfortunately side-effect of moving *after* the call to decode_fh, so the prober fsuid was not set when nfsd_acceptable was called, the 'permission' check did the wrong thing. This patch moves the nfsd_setuser call back where it was, and add as call in the other branch of the if. Cc: "J.

It was pointed out to me by Andi Kleen that if an oops has occured in interrupt context, then calling sleep() in the oops path will only cause a panic, and that it would be really better for it not to be in the path at all. This patch removes the ssleep() call and reworks the console message accordinly. I have a slght concern that the resulting console message is too long, feedback welcome. For powerpc it also unifies the 32bit and 64bit behaviour. Fror x86_64, this patch only updates the console message, as ssleep() is already not present.

The second class covers everyone except UDP because most people do the cache lookup directly before calling ip6_dst_lookup. This patch adds ip6_sk_dst_lookup for the first class. Similarly ip6_dst_store users can be divded into those that need to take the socket dst lock and those that don't.

From initial analysis, it seems that the strlen() called from selinux_string_to_sid() could run until it arbitrarily finds a zero, and possibly cause a kernel oops before then. The impact of this appears limited because the operation requires CAP_NET_ADMIN, which is essentially always root. Also, the module is not yet in wide use.

When linger2 is active, we check to see if the fin_wait2 timeout is longer than the timewait. If it is, we schedule the keepalive timer for the difference between the timewait timeout and the fin_wait2 timeout. When this orphan socket is seen by tcp_keepalive_timer() it will try to transform this fin_wait2 socket into a fin_wait2 mini-socket, again if linger2 is active. Not all paths were setting this initial keepalive timer correctly. The tcp input path was doing it correctly, but tcp_close() wasn't, potentially making the socket linger longer than it really needs to. Signed-off-by: David S.

I think increasing this counter after output a fragment successfully is better. And it should not be increased even though a fragment is created but failed to output. 2nd: If we send a big ICMP/ICMPv6 echo request to a host, and receive ICMP/ICMPv6 echo reply consisted of some fragments. As we know that in Linux kernel first fragmentation occurs in ICMP layer(maybe saying transport layer is better), but this is not the "real" fragmentation,just do some "pre-fragment" -- allocate space for date, and form a frag_list, etc. The "real" fragmentation happens in IP layer -- set offset and MF flag and so on. So I think in "fast path" for ip_fragment/ip6_fragment, if we send a fragment which "pre-fragment" by upper layer we should also increase "ipv6IfStatsOutFragCreates".

The skb_queue_head_init() function is used both in drivers for private use and in the core networking code. The usage models are vastly set of functions that is only softirq safe; while the driver usage tends to be more limited to a few hardirq safe accessor functions. Rather than annotating all 133+ driver usages, for now just split this lock into a per queue class. This change is obviously safe and probably should make 2.6.18.

Instead of creating a security context each time a unix datagram is sent, we only create the security context when the receiver requests it. This new design requires modification of the current unix_getsecpeer_dgram LSM hook and addition of two new hooks, namely, secid_to_secctx and release_secctx. The former retrieves the security context and the latter releases it. A hook is required for releasing the security context because it is up to the security module to decide how that's done. In the case of Selinux, it's a simple kfree operation. Acked-by: Stephen Smalley Signed-off-by: David S.

We found an issue in pal.S. According to the software runtime SPEC, The caller's output registers do not need to be preserved for caller. The callee may reuse input registers for any other purpose within the procedure. in ia64_pal_call_phys_stacked, input registers are copied to output registers before call into ia64_switch_mode_phys, then used to call into PAL. This assumes output registers are preserved in ia64_switch_mode_phys, which may not be true. In this particular case, ia64_switch_mode_phys alloc a null frame , and mask off psr.i. If an interrupt comes at this small window, or an MCA comes inside the procedure, output registers maybe changed, then the pal call may got some staled input registers. This patch moves the copies from input to output after ia64_switch_mode_phys to follow the software runtime convention. It also removed some unused labels in ia64_pal_call_phys_stacked.

We need to ignore the ZyXEL G220F as it is a virtual CDROM drive which includes the windows driver for this USB-WLAN adapter. After the windows driver is installed on a windows system, it converts it into a WLAN adapter (by ejecting the virtual disc). The virtual CDROM is of no interest to Linux users. The zd1211rw driver will automatically perform the eject operation, we just need to ensure that usb-storage does not claim the device.

Not doing so violates the buddy allocator algorithm. Also anyone using mem=XXX on boot line and not aligned to MAX_ORDER requires this patch in order to satisfy buddy allocator. vmem_map always starts at pfn 0. The potentially large MAX_ORDER on ia64 (due to hugetlbfs) requires that the end of vmem_map be aligned to MAX_ORDER_NR_PAGES.

Following are the brief description of changes 1. code cleanup to handle gso modification better 2. Move repeated code in rx path, to a common function s2io_chk_rx_buffers() 3. Bug fix in MSI interrupt 4. clear statistics when card is down 5. Avoid linked list traversing in lro aggregation. 6. Use pci_dma_sync_single_for_cpu for buffer0 in case of 2/3 buffer mode. 7. ethtool tso get/set functions to set clear NETIF_F_TSO6 8.

These were discovered when trying to use it to build an out-of-kernel version of STP. First it didn't pass the source address of the received packet in recvfrom(). It needs to copy the source address of received LLC packets into the socket control block. At the same time fix a security issue because there was uninitialized data leakage. Every recvfrom call was just copying out old data. Second, LLC should not merge multiple packets in one receive call on datagram sockets. LLC should preserve packet boundaries on SOCK_DGRAM. This fix goes against the old historical comments about UNIX98 semantics but without this fix SOCK_DGRAM is broken and useless. So either ANK's interpretation was incorect or UNIX98 standard was wrong. Signed-off-by: Stephen Hemminger Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

Since the EWMA exponent is typically around 9, queue lengths larger than 2^2 cause overflow. Whether the affected branch is taken when us_idle is as high as 1 second, depends on Scell_log, but with rather reasonable configuration Scell_log is large enough to cause p->Stab to have zero index, which always results zero shift (typically also few other small indices result in zero shift).

If the given window size is in the range of 8 .. 127, lapb_setparms() fails and returns an error value of LAPB_INVALUE, even if bit LAPB_EXTENDED in parms->mode is set.

This third check results true, so that we leave lapb_setparms() by 'goto out_put'.

However, this is a special case, because its parent process might have been frozen already and then we are unable to deliver the "freeze" signal to the traced process.

The retry logic of unqueue_me only works if we can guarantee, that the original value of q->lock_ptr is always a spinlock (Otherwise we overwrite kernel memory). We know that q->lock_ptr can change. I dont know what happens with the original spinlock, as I am not an expert with the futex code.

It seems to be intended that the implementation will use this hint to perform drop-behind of that part of the file when the application gets around to reading or writing it. However for reasons which aren't obvious (or sane?) I mapped POSIX_FADV_NOREUSE onto POSIX_FADV_WILLNEED. ie: it does readahead. That's daft. So for now, make POSIX_FADV_NOREUSE a no-op. This is a non-back-compatible change. If someone was using POSIX_FADV_NOREUSE to perform readahead, they lose. The likelihood is low. If/when we later implement POSIX_FADV_NOREUSE things will get interesting - to do it fully we'll need to maintain file offset/length ranges and peform all sorts of complex tricks, and managing the lifetime of those ranges' data structures will be interesting.. A sensible implementation would probably ignore the file range and would simply mark the entire file as needing some form of drop-behind treatment.

It's better to do resouce collision check before doing memory hot add, which will touch memory management structures. And add_section() should check section exists or not before calling sparse_add_one_section(). (sparse_add_one_section() will do another check anyway. but checking in memory_hotplug.c will be easy to understand.)

Before we assumed it was memory only, but it could be also IO. But this change show an hidden bug : some resources could be producer type that are not handled by pnp layer. So we should ignore the producer resources. This patch fixes bug 6292 (http://bugzilla.kernel.org/show_bug.cgi?id=6292). Some devices like PNP0A03 have 0xd00-0xffff and 0x0-0xcf7 as IO producer resources. Before correcting "address resources" parsing, it was seen as memory and was harmless, because nobody tried to reserve this memory range as it should be IO. With the correction it become IO resources, and make failed all others device that want to register IO in this range and use pnp layer (like a ISA sound card).

If the yield() took a long time (as it does on my OLPC prototype board when it's busy), we'd report a timeout even though the hardware was now ready. This fixes it, and also switches the yield() for a cond_resched() because we don't actually want to be _that_ nice about it. I see nice tightly-packed SMBus transactions now, rather than waiting for milliseconds between successive phases. Actually, we shouldn't be busy-waiting here at all. We should be using interrupts.

Currently it is impossible to reset provided by Qlogic QLA2xxx driver SCSI devices externally using corresponding sg devices, particularly via sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset() function checks if the input scsi_cmnd has its private data (CMD_SP()) attached. Then the found pointer isn't used anywhere inside of qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it doesn't have such private data. The attached patch removes check for non-NULL CMD_SP() from qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using corresponding sg devices. AV: change applies to bus/host reset handlers as well.

Remove system device class for xpram. It creates the directory hierarchy under /sys/devices/system/xpram/xpram0. The xpram0 directory is empty and it is always created while xpram1 and following devices are always missing, independent if the devices exist or not. Since the xpram devices are listed in /proc/partitions and /sys/block/ as slram the system device class for xpram is meaningless.

This scenario can cause the tx queue to be stopped forever if tg3_tx() has just freed up the entire tx_ring. The possibility of this happening should be very rare though. The following changes are made: 1. Add memory barrier to fix the above race condition. 2. Eliminate the private tx_lock altogether and rely solely on netif_tx_lock. This eliminates one spinlock in tg3_start_xmit() when the ring is full. 3. Because of 2, use netif_tx_lock in tg3_tx() before calling netif_wake_queue(). 4. Change TX_BUFFS_AVAIL to an inline function with a memory barrier. Herbert and David suggested using the memory barrier instead of volatile. 5. Check for the full wake queue condition before getting netif_tx_lock in tg3_tx(). This reduces the number of unnecessary spinlocks when the tx ring is full in a steady-state condition. 6. Update version to 3.65. Signed-off-by: Michael Chan Acked-by: Herbert Xu Signed-off-by: David S.

CPU1 CPU2 dst_run_gc() entered dst_run_gc() entered spin_lock(&dst_lock) ..... del_timer(&dst_gc_timer) fail to get lock .... mod_timer() <--- puts timer back to the list add_timer(&dst_gc_timer) <--- BUG because timer is in list already. Found during OpenVZ internal testing. At first we thought that it is OpenVZ specific as we added dst_run_gc(0) call in dst_dev_event(), but as Alexey pointed to me it is possible to trigger this condition in mainstream kernel. F.e. timer has fired on CPU2, but the handler was preeempted by an irq before dst_lock is tried. Meanwhile, someone on CPU1 adds an entry to gc list and starts the timer. If CPU2 was preempted long enough, this timer can expire simultaneously with resuming timer handler on CPU1, arriving exactly to the situation described.

We recently fixed an out-of-space deadlock in XFS, and part of that fix involved the addition of the XFS_ALLOC_FLAG_FREEING flag to some of the space allocator calls to indicate they're freeing space, not allocating it. There was a missed xfs_alloc_fix_freelist condition test that did not correctly test "flags". The same test would also test an uninitialised structure field (args->userdata) and depending on its value either would or would not return early with a critical buffer pointer set to NULL. This fixes that up, adds asserts to several places to catch future botches of this nature, and skips sections of xfs_alloc_fix_freelist that are irrelevent for the space-freeing case.

However, the following scenario is perfectly valid: QP_a: send_cq == CQ_x, recv_cq == CQ_y QP_b: send_cq == CQ_y, recv_cq == CQ_x The old mthca code simply locked send_cq and then recv_cq, which in this case could lead to an AB-BA deadlock if QP_a and QP_b were destroyed simultaneously. We can fix this by changing the locking code to lock the CQ with the lower CQ number first, which will create a consistent lock ordering. Also, the second CQ is locked with spin_lock_nested() to tell lockdep that we know what we're doing with the lock nesting. This bug was found by lockdep.

I misunderstood this intention when I changed xfrm_dst_check() to always return NULL. Now, when we purge a dst entry, by running dst_free() on it. This will set the dst->obsolete to a positive integer, and we want to return NULL in that case so that the socket does a relookup for the route. Thus, if dst->obsolete<0, let stale_bundle() validate the state, else always return NULL. In general, we need to do things more intelligently here because we flush too much state during rule changes.

This broke because skb_trim no longer allows paged packets to be trimmed. Paged packets must be given to one of the pskb_trim functions instead. This patch adds a new pskb_trim_unique function to cover the IPv4/IPv6 datagram output path scenario and replaces the corresponding skb_trim calls with it.

Basically it is possible for futex_unlock_pi to return without actually freeing the lock. This is due to buggy logic in the use of futex_handle_fault() and its attempt argument in a failure case. Looking at futex.c the logic is as follows: 1) In futex_unlock_pi() we start w/ ret=0 and we go down to the first futex_atomic_cmpxchg_inatomic(), where we find uval==-EFAULT. We then jump to the pi_faulted label. 2) From pi_faulted: We increment attempt, unlock the sem and hit the retry label. 3) From the retry label, with ret still zero, we again hit EFAULT on the first futex_atomic_cmpxchg_inatomic(), and again goto the pi_faulted label. 4) Again from pi_faulted: we increment attempt and enter the conditional, where we call futex_handle_fault. 5) futex_handle_fault fails, and we goto the out_unlock_release_sem label. 6) From out_unlock_release_sem we return, and since ret is still zero, we return without error, while never actually unlocking the lock. Issue #1: at the first futex_atomic_cmpxchg_inatomic() we should probably be setting ret=-EFAULT before jumping to pi_faulted: However in our case this doesn't really affect anything, as the glibc we're using ignores the error value from futex_unlock_pi(). Issue #2: Look at futex_handle_fault(), its first conditional will return -EFAULT if attempt is >= 2. However, from the "if(attempt++) futex_handle_fault(attempt)" logic above, we'll *never* call futex_handle_fault when attempt is less then two. So we never get a chance to even try to fault the page in. The following patch addresses these two issues by 1) Always setting ret to -EFAULT if futex_handle_fault fails, and 2) Removing the = in futex_handle_fault's (attempt >= 2) check. I'm really not sure this is the right fix, but wanted to bring it up so folks knew the issue is alive and well in the current -git tree. From looking at the git logs the logic was first introduced (then later copied to other places) in the following commit almost a year ago: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=4732efbeb997189d9f9b04708dc26bf8613ed721;hp=5b039e681b8c5f30aac9cc04385cc94be45d0823 Cc: Rusty Russell Cc: Ingo Molnar Acked-by: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman --- kernel/futex.c | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-) diff --git a/kernel/futex.c b/kernel/futex.c index c2b2e0b83abf..d4633c588f33 100644 --- a/kernel/futex.c +++ b/kernel/futex.c @@ -297,7 +297,7 @@ static int futex_handle_fault(unsigned long address, int attempt) struct vm_area_struct * vma; struct mm_struct *mm = current->mm; - if (attempt >= 2 || !(vma = find_vma(mm, address)) || + if (attempt > 2 || !(vma = find_vma(mm, address)) || vma->vm_start > address || !(vma->vm_flags & VM_WRITE)) return -EFAULT; @@ -747,8 +747,10 @@ retry: */ if (attempt++) { if (futex_handle_fault((unsigned long)uaddr2, - attempt)) + attempt)) { + ret = -EFAULT; goto out; + } goto retry; } @@ -1322,9 +1324,10 @@ static int do_futex_lock_pi(u32 __user *uaddr, int detect, int trylock, * still holding the mmap_sem. */ if (attempt++) { - if (futex_handle_fault((unsigned long)uaddr, attempt)) + if (futex_handle_fault((unsigned long)uaddr, attempt)) { + ret = -EFAULT; goto out_unlock_release_sem; - + } goto retry_locked; } @@ -1506,9 +1509,10 @@ pi_faulted: * still holding the mmap_sem. */ if (attempt++) { - if (futex_handle_fault((unsigned long)uaddr, attempt)) + if (futex_handle_fault((unsigned long)uaddr, attempt)) { + ret = -EFAULT; goto out_unlock; - + } goto retry_locked; } From 2b25742556b1a351ce4821f6feddcba23bdd930b Mon Sep 17 00:00:00 2001 From: Michal Januszewski Date: Sun, 13 Aug 2006 23:24:26 -0700 Subject: [PATCH 525/746] [PATCH] fbdev: include backlight.h only when __KERNEL__ is defined linux/backlight.h pulls in header files (eg. ioport.h) that break compilation of userspace programs.

This causes joydev.ko to not be automaticly loaded when inserting a joystick, resulting in a non working joystick (for the average user). In scripts/mod/file2alias.c is the following code for generating the input aliases: static void do_input(char *alias, kernel_ulong_t *arr, unsigned int min, unsigned int max) { unsigned int i; for (i = min; i < max; i++) if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) sprintf(alias + strlen(alias), "%X,*", i); } On 32 bits systems, this correctly generates "0,*" for the first alias, "8,*" for the second etc. However on 64 bits it generates: "0,*20,*" resp "8,*28,*" Notice how it adds 20 + first entry (hex) ! to the list of hex codes, which is 32 more then the first entry, thus is because the bit test above wraps at 32 bits instead of 64. scripts/mod/file2alias.c, line 379 reads: if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) That should be: if (arr[i / BITS_PER_LONG] & (1L << (i%BITS_PER_LONG))) Notice the added 'L' after the 1, otherwise that is an 32 bit int instead of a 64 bit long, and when that int gets shifted >= 32 times, appearantly the number by which to shift is wrapped at 5 bits ( % 32) causing it to test a bit 32 bits too low.

If xmon is enabled, the CPU(s) enter into the xmon debugger. Unfortunately, the secondary CPU(s) will return to the hung state when they exit from the debugger (returned from die() -> system_reset_exception()). This causes a problem in kdump since the hung CPU(s) will not respond to the IPI sent from kdump. This patch fixes the issue by calling crash_kexec_secondary() directly from system_reset_exception() without returning to the previous state. These secondary CPUs wait 5ms until the kdump boot is started by the primary CPU. In the case we exited from the debugger to "recover" (command 'x' in xmon) the primary and the secondary CPUs will all return from die() -> system_reset_exception() ->crash_kexec_secondary() wait 5ms, then return to the previous state. A kdump boot is not started in this case.

This second processor could have fetched the stream of text from the out-of-line single-stepping area *before* the probe registration completed, possibly due to an earlier (and a different) kprobe hit and hence would see stale data at the slot. Executing such an arbitrary instruction lead to a problem as reported in LTC bugzilla 23555. The correct solution is to call flush_icache_range() as soon as the instruction is copied for out-of-line single-stepping, so the correct instruction is seen on all processors.

Fix a subtle race condition between bnx2_start_xmit() and bnx2_tx_int() similar to the one in tg3 discovered by Herbert Xu: CPU0 CPU1 bnx2_start_xmit() if (tx_ring_full) { tx_lock bnx2_tx() if (!netif_queue_stopped) netif_stop_queue() if (!tx_ring_full) update_tx_ring netif_wake_queue() tx_unlock } Even though tx_ring is updated before the if statement in bnx2_tx_int() in program order, it can be re-ordered by the CPU as shown above. This scenario can cause the tx queue to be stopped forever if bnx2_tx_int() has just freed up the entire tx_ring. The possibility of this happening should be very rare though. The following changes are made, very much identical to the tg3 fix: 1. Add memory barrier to fix the above race condition. 2. Eliminate the private tx_lock altogether and rely solely on netif_tx_lock. This eliminates one spinlock in bnx2_start_xmit() when the ring is full. 3. Because of 2, use netif_tx_lock in bnx2_tx_int() before calling netif_wake_queue(). 4. Add memory barrier to bnx2_tx_avail(). 5. Add bp->tx_wake_thresh which is set to half the tx ring size. 6. Check for the full wake queue condition before getting netif_tx_lock in tg3_tx(). This reduces the number of unnecessary spinlocks when the tx ring is full in a steady-state condition.

These are: - check wether we can load another buff in start - update state handling in s3c2410_dma_lastxfer - only reload in irq if channel is not idle - more informative timeout errors (add source) - do not call request_irq() with irqs locked - added waitforstop function The patch also adds a S3C2410_DMAOP_STARTED for the occasions when the driver wants to ensure that the DMA system load state is resynced after loading.

This avoids device offline scenarios due to errors in the error handler. Background: Although the transport is using the scsi_timed_out functionality to restart the timeout if the rport is blocked, if the timeout has already fired before the block occurs, the eh handler still runs and can take the device offline. Ultimately, this window cannot be resolved without significant work in the error handler thread. Christoph noted the first level of these issues when he noted the poor error response handling by the error thread. We found, under heavy load and error testing, that time window from when the scsi_times_out() adds the io to the queue to when the scsi_error_handler gets around to servicing it, can be in the several seconds range. In most cases, these test conditions are highly unusual, but possible. As a result, we're stalling the error handler in this race window so that we can avoid the device_offline transitions.

Altered platform_data structures as well as initial setup routines relevant to fs_enet. Changes to the mpc8560ads ppc/ code are also introduced, but mainly as reference, since the entire board support is going to appear in arch/powerpc.

Class codes for devices which are indicated to be absent by PCS are cleared to ATA_DEV_NONE. This fixes ghost device problem reported on ICH6 and 7. This patch moves PCS handling from prereset to softreset, which makes two behavior changes. * perform softreset even when PCS indicates no device * PCS handling is repeated before retrying softresets due to reset failures. Both behavior changes are intended and more consistent with how other drivers behave.

The first is that there is a race between do_gettimeofday and the timer interrupt: 1. do_gettimeofday does get_tb() 2. decrementer exception on boot cpu which runs timer_recalc_offset, which also samples the timebase and updates the do_gtod structure with a greater timebase value. 3. do_gettimeofday calls __do_gettimeofday, which leads to the negative result from tb_val - temp_varp->tb_orig_stamp. The second is caused by taking the boot cpu offline, which can cause the value of tb_last_jiffy to be increased past the currently available timebase, causing the same underflow as above.

Alright, this one is only triggered when slab debugging is enabled. The slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary. The free path makes use of this assumption and uses the lowest nibble to pass around an index into an array of kmem_cache pointers. With slab debugging turned on, the slab is still aligned, but the "working" object pointer is not. This would break the assumption above that a full nibble is available for the PGF_CACHENUM_MASK. The following patch reduces PGF_CACHENUM_MASK to cover only the two least significant bits, which is enough to cover the current number of 4 pgtable cache types. Then use this constant to mask out the appropriate part of the huge pte pointer.

A typical mkdir(2) calls two inode_operations: lookup and mkdir. The lookup operation would fail with ENOENT in common case. I think it is unnecessary because the subsequent mkdir operation can check it. In case of creat(2), lookup operation is called with the LOOKUP_CREATE flag, so individual filesystem can omit real lookup. e.g. nfs_lookup().

Also add a check into the main XDR decode handler to make sure that the amount of data is a multiple of four bytes (as specified by RFC-1014).

Original code attempts to retry PLOGIs to fcports that are FCP_TARGETs only. If the driver never performed a successful PLOGI/PRLI, the port-type would never be assigned, and the relogin logic would silently drop the request (and thus the port would not be recognized and registered). The fix is relatively straightforward, drop the FCP_TARGET-only check.

Then after the command runs, we end up copying that old_cmnd var which has the new cmnd to the scsi command buffer. When this command gets recent, all types of fun things happen like getting TUR or START_STOP commands with data and scatterlists. This patch made against scsi-rc-fixes, has the callers of scsi_send_eh_cmnd pass in the command so scsi_send_eh_cmnd can do the right thing.

Without this our special test settings could remain seriously confusing the system BIOS's setup menu. Both are very much related and are must haves, to avoid messing up the uguru CMOS settings. Detailed changes: - Much improved timeout / wait for status handling. Many thanks to Sunil Kumar, for all his testing, ideas and patches! The code now first busy waits, polling the uguru for the expected status as this usually succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn in timeout conditions, the amount of busy waiting has been halved from previous versions (120 tries instead of 250). This is not a problem, because this version goes to sleep after 120 attemps for 1 jiffy and then tries again, it does this sleep and try again 5 times before finally giving up. This (almost?) completly removes the timeout errors some people have seen regulary. Apparently some older uguru versions sometimes are distracted for a (relatively) long time. This solves this. - These timeout errors not only occur in the sending address part of reading the uguru but also in the wait for read state, so errors in this state are now handled as retryable just like send address state errors and are only logged and reported to userspace if 3 executive tries fail. - Fix a very nasty bug in the bank1 sensor type detection code, where it would not restore the original settings in any of the error paths! - Since not successfully restoring the original settings can seriously confuse the system BIOS (hang when entering the relevant setup menu), we now try restoring them 3 times before giving up.

The patch changes the PCI init code to have PCBIOS as last fallback, yet the PCBIOS code still has to run first to set pcibios_last_bus to the value reported by the BIOS. this is needed in case legacy PCI probing (arch/i386/pci/legacy.c) is used to detect peer busses. using direct access if available fixes the cardbus problems.

This would cause kernel to send Tcp Segmentation Offload packets for IPV6 data to devices that can't handle it. It caused the sky2 driver to lock http://bugzilla.kernel.org/show_bug.cgi?id=7050 and the e1000 would generate bogus packets. I can't blame the hardware for gagging if the upper layers feed it garbage. This was a new bug in 2.6.18 introduced with GSO support. Signed-off-by: Stephen Hemminger Signed-off-by: David S.

CCID3 is meant to alter sending rate based on RTT and loss. The performance was verified against: http://wand.net.nz/~perry/max_download.php For example I tested with netem and had the following parameters: Delayed Acks 1, MSS 256 bytes, RTT 105 ms, packet loss 5%. This gives a theoretical speed of 71.9 Kbits/s. I measured across three runs with this patch set and got 70.1 Kbits/s. Without this patchset the average was 232 Kbits/s which means Linux can't be used for CCID3 research properly. I also tested with netem turned off so box just acting as router with 1.2 msec RTT. The performance with this is the same with or without the patch at around 30 Mbit/s. Signed off by: Ian McDonald Signed-off-by: David S.

On an nForce4-equipped machine with two SATA disk in raid1 setup using dmraid, we experienced frequent deadlock of the system under high i/o load. 'cat /dev/zero > ~/zero' was the most reliable way to reproduce them: Randomly after a few GB, 'cp' would be left in 'D' state along with kjournald and kmirrord. The functions cp and kjournald were blocked in did vary, but kmirrord's wchan always pointed to 'mempool_alloc()'. We've seen this pattern on 2.6.15 and 2.6.17 kernels. http://lkml.org/lkml/2005/4/20/142 indicates that this problem has been around even before. So much for the facts, here's my interpretation: mempool_alloc() first tries to atomically allocate the requested memory, or falls back to hand out preallocated chunks from the mempool. If both fail, it puts the calling process (kmirrord in this case) on a private waitqueue until somebody refills the pool. Where the only 'somebody' is kmirrord itself, so we have a deadlock. I worked around this problem by falling back to a (blocking) kmalloc when before kmirrord would have ended up on the waitqueue. This defeats part of the benefits of using the mempool, but at least keeps the system running. And it could be done with a two-line change. Note that mempool_alloc() clears the GFP_NOIO flag internally, and only uses it to decide whether to wait or return an error if immediate allocation fails, so the attached patch doesn't change behaviour in the non-deadlocking case. Path is against current git (2.6.18-rc4), but should apply to earlier versions as well. I've tested on 2.6.15, where this patch makes the difference between random lockup and a stable system.

After I fixed this I found that uploading firmware in a system with multiple cards causes a kernel oops. I had a look in the recent moxa sources and found that they do some kind of locking there. Applying this lock fixed the problem. Alan sayeth: Checksum changes are clearly correct. Other changes is an improvement but not I think enough to handle malicious firmware attacks.

This is wrong behaviour, fragment may be NOT allocated, but mapped, this happened because of "block map" function not checked allocated fragment or not, it just take address of the first fragment in the block, add offset of fragment and return result, this is correct behaviour in almost all situation except call from ufs_truncate. 2) Almost all implementation of UFS, which I can investigate have such "defect": if you have full disk, and try truncate file, for example 3GB to 2MB, and have hole in this region, truncate return -ENOSPC. I tried evade from this problem, but "block allocation" algorithm is tied to right value of i_lastfrag, and fix of this corner case may slow down of ordinaries scenarios, so this patch makes behavior of "truncate" operations similar to what other UFS implementations do.

Kernel +clients write into the channel buffers using efficient write +functions; these automatically log into the current cpu's channel +buffer. User space applications mmap() or read() from the relay files +and retrieve the data as it becomes available. The relay files +themselves are files created in a host filesystem, e.g. debugfs, and +are associated with the channel buffers using the API described below. + +The format of the data logged into the channel buffers is completely +up to the kernel client; the relay interface does however provide +hooks which allow kernel clients to impose some structure on the +buffer data. The relay interface doesn't implement any form of data +filtering - this also is left to the kernel client. The purpose is to +keep things as simple as possible. + +This document provides an overview of the relay interface API. The +details of the function parameters are documented along with the +functions in the relay interface code - please see that for details. + +Semantics +========= + +Each relay channel has one buffer per CPU, each buffer has one or more +sub-buffers. Messages are written to the first sub-buffer until it is +too full to contain a new message, in which case it it is written to +the next (if available). Messages are never split across sub-buffers. +At this point, userspace can be notified so it empties the first +sub-buffer, while the kernel continues writing to the next. + +When notified that a sub-buffer is full, the kernel knows how many +bytes of it are padding i.e. unused space occurring because a complete +message couldn't fit into a sub-buffer. Userspace can use this +knowledge to copy only valid data. + +After copying it, userspace can notify the kernel that a sub-buffer +has been consumed. + +A relay channel can operate in a mode where it will overwrite data not +yet collected by userspace, and not wait for it to be consumed. + +The relay channel itself does not provide for communication of such +data between userspace and kernel, allowing the kernel side to remain +simple and not impose a single interface on userspace. It does +provide a set of examples and a separate helper though, described +below. + +The read() interface both removes padding and internally consumes the +read sub-buffers; thus in cases where read(2) is being used to drain +the channel buffers, special-purpose communication between kernel and +user isn't necessary for basic operation. + +One of the major goals of the relay interface is to provide a low +overhead mechanism for conveying kernel data to userspace. While the +read() interface is easy to use, it's not as efficient as the mmap() +approach; the example code attempts to make the tradeoff between the +two approaches as small as possible. + +klog and relay-apps example code +================================ + +The relay interface itself is ready to use, but to make things easier, +a couple simple utility functions and a set of examples are provided. + +The relay-apps example tarball, available on the relay sourceforge +site, contains a set of self-contained examples, each consisting of a +pair of .c files containing boilerplate code for each of the user and +kernel sides of a relay application. When combined these two sets of +boilerplate code provide glue to easily stream data to disk, without +having to bother with mundane housekeeping chores. + +The 'klog debugging functions' patch (klog.patch in the relay-apps +tarball) provides a couple of high-level logging functions to the +kernel which allow writing formatted text or raw data to a channel, +regardless of whether a channel to write into exists or not, or even +whether the relay interface is compiled into the kernel or not. These +functions allow you to put unconditional 'trace' statements anywhere +in the kernel or kernel modules; only when there is a 'klog handler' +registered will data actually be logged (see the klog and kleak +examples for details). + +It is of course possible to use the relay interface from scratch, +i.e. without using any of the relay-apps example code or klog, but +you'll have to implement communication between userspace and kernel, +allowing both to convey the state of buffers (full, empty, amount of +padding). The read() interface both removes padding and internally +consumes the read sub-buffers; thus in cases where read(2) is being +used to drain the channel buffers, special-purpose communication +between kernel and user isn't necessary for basic operation. Things +such as buffer-full conditions would still need to be communicated via +some channel though. + +klog and the relay-apps examples can be found in the relay-apps +tarball on http://relayfs.sourceforge.net + +The relay interface user space API +================================== + +The relay interface implements basic file operations for user space +access to relay channel buffer data. Here are the file operations +that are available and some comments regarding their behavior: + +open() enables user to open an _existing_ channel buffer. + +mmap() results in channel buffer being mapped into the caller's + memory space. Note that you can't do a partial mmap - you + must map the entire file, which is NRBUF * SUBBUFSIZE. + +read() read the contents of a channel buffer. The bytes read are + 'consumed' by the reader, i.e. they won't be available + again to subsequent reads. If the channel is being used + in no-overwrite mode (the default), it can be read at any + time even if there's an active kernel writer. If the + channel is being used in overwrite mode and there are + active channel writers, results may be unpredictable - + users should make sure that all logging to the channel has + ended before using read() with overwrite mode. Sub-buffer + padding is automatically removed and will not be seen by + the reader. + +sendfile() transfer data from a channel buffer to an output file + descriptor. Sub-buffer padding is automatically removed + and will not be seen by the reader. + +poll() POLLIN/POLLRDNORM/POLLERR supported.

Each channel buffer will have an associated file +created for it in the host filesystem, which can be and mmapped or +read from in user space. The files are named basename0...basenameN-1 +where N is the number of online cpus, and by default will be created +in the root of the filesystem (if the parent param is NULL). If you +want a directory structure to contain your relay files, you should +create it using the host filesystem's directory creation function, +e.g. debugfs_create_dir(), and pass the parent directory to +relay_open(). Users are responsible for cleaning up any directory +structure they create, when the channel is closed - again the host +filesystem's directory removal functions should be used for that, +e.g. debugfs_remove(). + +In order for a channel to be created and the host filesystem's files +associated with its channel buffers, the user must provide definitions +for two callback functions, create_buf_file() and remove_buf_file(). +create_buf_file() is called once for each per-cpu buffer from +relay_open() and allows the user to create the file which will be used +to represent the corresponding channel buffer. The callback should +return the dentry of the file created to represent the channel buffer. +remove_buf_file() must also be defined; it's responsible for deleting +the file(s) created in create_buf_file() and is called during +relay_close(). + +Here are some typical definitions for these callbacks, in this case +using debugfs: + +/* + * create_buf_file() callback. Creates relay file in debugfs. + */ +static struct dentry *create_buf_file_handler(const char *filename, + struct dentry *parent, + int mode, + struct rchan_buf *buf, + int *is_global) +{ + return debugfs_create_file(filename, mode, parent, buf, + &relay_file_operations); +} + +/* + * remove_buf_file() callback. Removes relay file from debugfs. + */ +static int remove_buf_file_handler(struct dentry *dentry) +{ + debugfs_remove(dentry); + + return 0; +} + +/* + * relay interface callbacks + */ +static struct rchan_callbacks relay_callbacks = +{ + .create_buf_file = create_buf_file_handler, + .remove_buf_file = remove_buf_file_handler, +}; + +And an example relay_open() invocation using them: + + chan = relay_open("cpu", NULL, SUBBUF_SIZE, N_SUBBUFS, &relay_callbacks); + +If the create_buf_file() callback fails, or isn't defined, channel +creation and thus relay_open() will fail. + +The total size of each per-cpu buffer is calculated by multiplying the +number of sub-buffers by the sub-buffer size passed into relay_open(). +The idea behind sub-buffers is that they're basically an extension of +double-buffering to N buffers, and they also allow applications to +easily implement random-access-on-buffer-boundary schemes, which can +be important for some high-volume applications. The number and size +of sub-buffers is completely dependent on the application and even for +the same application, different conditions will warrant different +values for these parameters at different times. Typically, the right +values to use are best decided after some experimentation; in general, +though, it's safe to assume that having only 1 sub-buffer is a bad +idea - you're guaranteed to either overwrite data or lose events +depending on the channel mode being used. + +The create_buf_file() implementation can also be defined in such a way +as to allow the creation of a single 'global' buffer instead of the +default per-cpu set. This can be useful for applications interested +mainly in seeing the relative ordering of system-wide events without +the need to bother with saving explicit timestamps for the purpose of +merging/sorting per-cpu files in a postprocessing step. + +To have relay_open() create a global buffer, the create_buf_file() +implementation should set the value of the is_global outparam to a +non-zero value in addition to creating the file that will be used to +represent the single buffer. In the case of a global buffer, +create_buf_file() and remove_buf_file() will be called only once. The +normal channel-writing functions, e.g. relay_write(), can still be +used - writes from any cpu will transparently end up in the global +buffer - but since it is a global buffer, callers should make sure +they use the proper locking for such a buffer, either by wrapping +writes in a spinlock, or by copying a write function from relay.h and +creating a local version that internally does the proper locking. + +Channel 'modes' +--------------- + +relay channels can be used in either of two modes - 'overwrite' or +'no-overwrite'. The mode is entirely determined by the implementation +of the subbuf_start() callback, as described below. The default if no +subbuf_start() callback is defined is 'no-overwrite' mode. If the +default mode suits your needs, and you plan to use the read() +interface to retrieve channel data, you can ignore the details of this +section, as it pertains mainly to mmap() implementations. + +In 'overwrite' mode, also known as 'flight recorder' mode, writes +continuously cycle around the buffer and will never fail, but will +unconditionally overwrite old data regardless of whether it's actually +been consumed. In no-overwrite mode, writes will fail, i.e. data will +be lost, if the number of unconsumed sub-buffers equals the total +number of sub-buffers in the channel. It should be clear that if +there is no consumer or if the consumer can't consume sub-buffers fast +enough, data will be lost in either case; the only difference is +whether data is lost from the beginning or the end of a buffer. + +As explained above, a relay channel is made of up one or more +per-cpu channel buffers, each implemented as a circular buffer +subdivided into one or more sub-buffers. Messages are written into +the current sub-buffer of the channel's current per-cpu buffer via the +write functions described below. Whenever a message can't fit into +the current sub-buffer, because there's no room left for it, the +client is notified via the subbuf_start() callback that a switch to a +new sub-buffer is about to occur. The client uses this callback to 1) +initialize the next sub-buffer if appropriate 2) finalize the previous +sub-buffer if appropriate and 3) return a boolean value indicating +whether or not to actually move on to the next sub-buffer. + +To implement 'no-overwrite' mode, the userspace client would provide +an implementation of the subbuf_start() callback something like the +following: + +static int subbuf_start(struct rchan_buf *buf, + void *subbuf, + void *prev_subbuf, + unsigned int prev_padding) +{ + if (prev_subbuf) + *((unsigned *)prev_subbuf) = prev_padding; + + if (relay_buf_full(buf)) + return 0; + + subbuf_start_reserve(buf, sizeof(unsigned int)); + + return 1; +} + +If the current buffer is full, i.e. all sub-buffers remain unconsumed, +the callback returns 0 to indicate that the buffer switch should not +occur yet, i.e. until the consumer has had a chance to read the +current set of ready sub-buffers. For the relay_buf_full() function +to make sense, the consumer is reponsible for notifying the relay +interface when sub-buffers have been consumed via +relay_subbufs_consumed(). Any subsequent attempts to write into the +buffer will again invoke the subbuf_start() callback with the same +parameters; only when the consumer has consumed one or more of the +ready sub-buffers will relay_buf_full() return 0, in which case the +buffer switch can continue. + +The implementation of the subbuf_start() callback for 'overwrite' mode +would be very similar: + +static int subbuf_start(struct rchan_buf *buf, + void *subbuf, + void *prev_subbuf, + unsigned int prev_padding) +{ + if (prev_subbuf) + *((unsigned *)prev_subbuf) = prev_padding; + + subbuf_start_reserve(buf, sizeof(unsigned int)); + + return 1; +} + +In this case, the relay_buf_full() check is meaningless and the +callback always returns 1, causing the buffer switch to occur +unconditionally. It's also meaningless for the client to use the +relay_subbufs_consumed() function in this mode, as it's never +consulted. + +The default subbuf_start() implementation, used if the client doesn't +define any callbacks, or doesn't define the subbuf_start() callback, +implements the simplest possible 'no-overwrite' mode, i.e. it does +nothing but return 0. + +Header information can be reserved at the beginning of each sub-buffer +by calling the subbuf_start_reserve() helper function from within the +subbuf_start() callback. This reserved area can be used to store +whatever information the client wants. In the example above, room is +reserved in each sub-buffer to store the padding count for that +sub-buffer. This is filled in for the previous sub-buffer in the +subbuf_start() implementation; the padding value for the previous +sub-buffer is passed into the subbuf_start() callback along with a +pointer to the previous sub-buffer, since the padding value isn't +known until a sub-buffer is filled. The subbuf_start() callback is +also called for the first sub-buffer when the channel is opened, to +give the client a chance to reserve space in it. In this case the +previous sub-buffer pointer passed into the callback will be NULL, so +the client should check the value of the prev_subbuf pointer before +writing into the previous sub-buffer. + +Writing to a channel +-------------------- + +Kernel clients write data into the current cpu's channel buffer using +relay_write() or __relay_write(). relay_write() is the main logging +function - it uses local_irqsave() to protect the buffer and should be +used if you might be logging from interrupt context. If you know +you'll never be logging from interrupt context, you can use +__relay_write(), which only disables preemption. These functions +don't return a value, so you can't determine whether or not they +failed - the assumption is that you wouldn't want to check a return +value in the fast logging path anyway, and that they'll always succeed +unless the buffer is full and no-overwrite mode is being used, in +which case you can detect a failed write in the subbuf_start() +callback by calling the relay_buf_full() helper function. + +relay_reserve() is used to reserve a slot in a channel buffer which +can be written to later. This would typically be used in applications +that need to write directly into a channel buffer without having to +stage data in a temporary buffer beforehand. Because the actual write +may not happen immediately after the slot is reserved, applications +using relay_reserve() can keep a count of the number of bytes actually +written, either in space reserved in the sub-buffers themselves or as +a separate array. See the 'reserve' example in the relay-apps tarball +at http://relayfs.sourceforge.net for an example of how this can be +done. Because the write is under control of the client and is +separated from the reserve, relay_reserve() doesn't protect the buffer +at all - it's up to the client to provide the appropriate +synchronization when using relay_reserve(). + +Closing a channel +----------------- + +The client calls relay_close() when it's finished using the channel. +The channel and its associated buffers are destroyed when there are no +longer any references to any of the channel buffers. relay_flush() +forces a sub-buffer switch on all the channel buffers, and can be used +to finalize and process the last sub-buffers before the channel is +closed. + +Misc +---- + +Some applications may want to keep a channel around and re-use it +rather than open and close a new channel for each use. relay_reset() +can be used for this purpose - it resets a channel to its initial +state without reallocating channel buffer memory or destroying +existing mappings. It should however only be called when it's safe to +do so, i.e. when the channel isn't currently being written to. + +Finally, there are a couple of utility callbacks that can be used for +different purposes. buf_mapped() is called whenever a channel buffer +is mmapped from user space and buf_unmapped() is called when it's +unmapped. The client can use this notification to trigger actions +within the kernel application, such as enabling/disabling logging to +the channel. + + +Resources +========= + +For news, example code, mailing list, etc. see the relay interface homepage: + + http://relayfs.sourceforge.net + + +Credits +======= + +The ideas and specs for the relay interface came about as a result of +discussions on tracing involving the following: + +Michel Dagenais +Richard Moore +Bob Wisniewski +Karim Yaghmour +Tom Zanussi + +Also thanks to Hubertus Franke for a lot of useful suggestions and bug +reports. diff --git a/Documentation/filesystems/relayfs.txt b/Documentation/filesystems/relayfs.txt deleted file mode 100644 index 5832377b7340..000000000000 --- a/Documentation/filesystems/relayfs.txt +++ /dev/null @@ -1,442 +0,0 @@ - -relayfs - a high-speed data relay filesystem -============================================ - -relayfs is a filesystem designed to provide an efficient mechanism for -tools and facilities to relay large and potentially sustained streams -of data from kernel space to user space. - -The main abstraction of relayfs is the 'channel'. A channel consists -of a set of per-cpu kernel buffers each represented by a file in the -relayfs filesystem. Kernel clients write into a channel using -efficient write functions which automatically log to the current cpu's -channel buffer. User space applications mmap() the per-cpu files and -retrieve the data as it becomes available. - -The format of the data logged into the channel buffers is completely -up to the relayfs client; relayfs does however provide hooks which -allow clients to impose some structure on the buffer data. Nor does -relayfs implement any form of data filtering - this also is left to -the client. The purpose is to keep relayfs as simple as possible. - -This document provides an overview of the relayfs API. The details of -the function parameters are documented along with the functions in the -filesystem code - please see that for details. - -Semantics -========= - -Each relayfs channel has one buffer per CPU, each buffer has one or -more sub-buffers. Messages are written to the first sub-buffer until -it is too full to contain a new message, in which case it it is -written to the next (if available). Messages are never split across -sub-buffers. At this point, userspace can be notified so it empties -the first sub-buffer, while the kernel continues writing to the next. - -When notified that a sub-buffer is full, the kernel knows how many -bytes of it are padding i.e. unused. Userspace can use this knowledge -to copy only valid data. - -After copying it, userspace can notify the kernel that a sub-buffer -has been consumed. - -relayfs can operate in a mode where it will overwrite data not yet -collected by userspace, and not wait for it to consume it. - -relayfs itself does not provide for communication of such data between -userspace and kernel, allowing the kernel side to remain simple and -not impose a single interface on userspace. It does provide a set of -examples and a separate helper though, described below. - -klog and relay-apps example code -================================ - -relayfs itself is ready to use, but to make things easier, a couple -simple utility functions and a set of examples are provided. - -The relay-apps example tarball, available on the relayfs sourceforge -site, contains a set of self-contained examples, each consisting of a -pair of .c files containing boilerplate code for each of the user and -kernel sides of a relayfs application; combined these two sets of -boilerplate code provide glue to easily stream data to disk, without -having to bother with mundane housekeeping chores. - -The 'klog debugging functions' patch (klog.patch in the relay-apps -tarball) provides a couple of high-level logging functions to the -kernel which allow writing formatted text or raw data to a channel, -regardless of whether a channel to write into exists or not, or -whether relayfs is compiled into the kernel or is configured as a -module. These functions allow you to put unconditional 'trace' -statements anywhere in the kernel or kernel modules; only when there -is a 'klog handler' registered will data actually be logged (see the -klog and kleak examples for details). - -It is of course possible to use relayfs from scratch i.e. without -using any of the relay-apps example code or klog, but you'll have to -implement communication between userspace and kernel, allowing both to -convey the state of buffers (full, empty, amount of padding). - -klog and the relay-apps examples can be found in the relay-apps -tarball on http://relayfs.sourceforge.net - - -The relayfs user space API -========================== - -relayfs implements basic file operations for user space access to -relayfs channel buffer data. Here are the file operations that are -available and some comments regarding their behavior: - -open() enables user to open an _existing_ buffer. - -mmap() results in channel buffer being mapped into the caller's - memory space. Note that you can't do a partial mmap - you must - map the entire file, which is NRBUF * SUBBUFSIZE. - -read() read the contents of a channel buffer. The bytes read are - 'consumed' by the reader i.e. they won't be available again - to subsequent reads. If the channel is being used in - no-overwrite mode (the default), it can be read at any time - even if there's an active kernel writer. If the channel is - being used in overwrite mode and there are active channel - writers, results may be unpredictable - users should make - sure that all logging to the channel has ended before using - read() with overwrite mode. - -poll() POLLIN/POLLRDNORM/POLLERR supported. User applications are - notified when sub-buffer boundaries are crossed. - -close() decrements the channel buffer's refcount. When the refcount - reaches 0 i.e. when no process or kernel client has the buffer - open, the channel buffer is freed. - - -In order for a user application to make use of relayfs files, the -relayfs filesystem must be mounted.

If we - shut down a clean array, - restart with one (or more) drive(s) missing - make some changes - pause, so that they array gets marked 'clean', the event count on the superblock of included drives will be the same as that of the removed drives. So adding the removed drive back in will cause it to be included with no resync. To avoid this, we only update the eventcount backwards when the array is not degraded. In this case there can (should) be no non-connected drives that we can get confused with, and this is the particular case where updating-backwards is valuable.

Make this top cpus file read-only. On systems that have cpusets configured in their kernel, but that aren't actively using cpusets (for some distros, this covers the majority of systems) all tasks end up in the top cpuset. If that system does support CPU hotplug, then these tasks cannot make use of CPUs that are added after system boot, because the CPUs are not allowed in the top cpuset. This is a surprising regression over earlier kernels that didn't have cpusets enabled. In order to keep the behaviour of cpusets consistent between systems actively making use of them and systems not using them, this patch changes the behaviour of the 'cpus' file in the top (root) cpuset, making it read only, and making it automatically track the value of cpu_online_map. Thus tasks in the top cpuset will have automatic use of hot plugged CPUs allowed by their cpuset.
