um: Support suspend to RAM
With all the previous bits in place, we can now also support suspend to RAM, in the sense that everything is suspended, not just most, including userspace, processes like in s2idle. Since um_idle_sleep() now waits forever, we can simply call that to "suspend" the system. As before, you can wake it up using SIGUSR1 since we're just in a pause() call that only needs to return. In order to implement selective resume from certain devices, and not have any arbitrary device interrupt wake up, suspend interrupts by removing SIGIO notification (O_ASYNC) from all the FDs that are not supposed to wake up the system. However, swap out the handler so we don't actually handle the SIGIO as an interrupt. Since we're in pause(), the mere act of receiving SIGIO wakes us up, and then after things have been restored enough, re-set O_ASYNC for all previously suspended FDs, reinstall the proper SIGIO handler, and send SIGIO to self to process anything that might now be pending.

um: time: Fix read_persistent_clock64() in time-travel
In time-travel mode, we've relied on read_persistent_clock64() being called only once at system startup, but this is both the right thing to call from the pseudo-RTC, and also gets called by the timekeeping core during suspend/resume. Thus, fix this to always fall make use of the time_travel_time in any time-travel mode, initializing time_travel_start at boot to the right value depending on the time-travel mode.

um: Simplify os_idle_sleep() and sleep longer
There really is no reason to pass the amount of time we should sleep, especially since it's just hard-coded to one second. Additionally, one second isn't really all that long, and as we are expecting to be woken up by a signal, we can sleep longer and avoid doing some work every second, so replace the current clock_nanosleep() with just an empty select() that can _only_ be woken up by a signal. We can also remove the deliver_alarm() since we don't need to do that when we got e.g. SIGIO that woke us up, and if we got SIGALRM the signal handler will actually (have) run, so it's just unnecessary extra work. Similarly, in time-travel mode, just program the wakeup event from idle to be S64_MAX, which is basically the most you could ever simulate to. Of course, you should already have an event in the list that's earlier and will cause a wakeup, normally that's the regular timer interrupt, though in suspend it may (later) also be an RTC event. Since actually getting to this point would be a bug and you can't ever get out again, panic() on it in the time control code.

um: Simplify IRQ handling code
Reduce dynamic allocations (and thereby cache misses) by simply
embedding the registration data for IRQs in the irq_entry, we
never supported these being really dynamic anyway as only one
was ever allowed ("Trying to reregister ...").
Lockless behaviour is preserved by removing the FD from the poll
set appropriately, but we use reg->events to indicate whether or
not this entry is used, rather than dynamically allocating them.
Also port the list of IRQ entries to list_head instead of the
current open-coded singly-linked list implementation, just for
sanity.

um: Remove IRQ_NONE type
We don't actually use this in um_request_irq(), so it can never be assigned. It's also not clear what that would be useful for, so just remove it. This results in quite a number of cleanups, all the way to removing the "SIGIO on close" startup check, since the data it assigns (pty_close_sigio) is not used anymore. While at it, also make this an enum so we get a minimum of type checking, and remove the IRQ_NONE hack in virtio since we now no longer have the name twice.

um: irq: Clean up and rename struct irq_fd
This really shouldn't be called "irq_fd" since it doesn't carry an fd. Well, it used to, apparently, but that struct member is unused. Rename it to "irq_reg" since it more accurately reflects a registered interrupt, and remove the unused 'next' and 'fd' members from the struct as well. While at it, also move it to the implementation, it's not used anywhere else, and the header file is shared with the userspace components.

um: Support dynamic IRQ allocation
It's cumbersome and error-prone to keep adding fixed IRQ numbers, and for proper device wakeup support for the virtio/vhost-user support we need to have different IRQs for each device. Even if in theory two IRQs (with and without wake) might be sufficient, it's much easier to reason about it when we have dynamic number assignment. It also makes it easier to add new devices that may dynamically exist or depending on the configuration, etc. Add support for this, up to 64 IRQs (the same limit as epoll FDs we have right now). Since it's not easy to port all the existing places to dynamic allocation (some data is statically initialized) keep the low numbers are reserved for the existing hard-coded IRQ numbers.

um: ubd: Set device serial attribute from cmdline
Adds the ability to set the UBD device serial number from the commandline, disabling the serial number functionality by default. In some cases it may be useful to set a serial to the UBD device, such that downstream users (i.e. udev) can use this information to better describe the hardware to the user from the UML cmdline. In our case we use this parameter to create some entries under /dev/disk/by-ubd-id/ for each of the UBD devices passed through the UML cmdline.

um: line: Don't free winch (with IRQ) under spinlock
Lockdep correctly complains that one shouldn't call um_free_irq() with free_irq() inside under a spinlock since that will attempt to acquire a mutex. Rearrange the code to keep the list manipulations under the lock while moving the actual freeing outside of it, to avoid this. In particular, this removes the lockdep complaint at shutdown that I was seeing with lockdep enabled.

um: ubd: Submit all data segments atomically
Internally, UBD treats each physical IO segment as a separate command to be submitted in the execution pipe. If the pipe returns a transient error after a few segments have already been written, UBD will tell the block layer to requeue the request, but there is no way to reclaim the segments already submitted. When a new attempt to dispatch the request is done, those segments already submitted will get duplicated, causing the WARN_ON below in the best case, and potentially data corruption. In my system, running a UML instance with 2GB of RAM and a 50M UBD disk, I can reproduce the WARN_ON by simply running mkfs.fvat against the disk on a freshly booted system. There are a few ways to around this, like reducing the pressure on the pipe by reducing the queue depth, which almost eliminates the occurrence of the problem, increasing the pipe buffer size on the host system, or by limiting the request to one physical segment, which causes the block layer to submit way more requests to resolve a single operation. Instead, this patch modifies the format of a UBD command, such that all segments are sent through a single element in the communication pipe, turning the command submission atomic from the point of view of the block layer. The new format has a variable size, depending on the number of elements, and looks like this: +------------+-----------+-----------+------------ | cmd_header | segment 0 | segment 1 | segment ... +------------+-----------+-----------+------------ With this format, we push a pointer to cmd_header in the submission pipe. This has the advantage of reducing the memory footprint of executing a single request, since it allow us to merge some fields in the header. It is possible to reduce even further each segment memory footprint, by merging bitmap_words and cow_offset, for instance, but this is not the focus of this patch and is left as future work. One issue with the patch is that for a big number of segments, we now perform one big memory allocation instead of multiple small ones, but I wasn't able to trigger any real issues or -ENOMEM because of this change, that wouldn't be reproduced otherwise. This was tested using fio with the verify-crc32 option, and by running an ext4 filesystem over this UBD device. The original WARN_ON was: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at lib/refcount.c:28 refcount_warn_saturate+0x13f/0x141 refcount_t: underflow; use-after-free.

um: random: Register random as hwrng-core device
The UML random driver creates a dummy device under the guest,
/dev/hw_random. When this file is read from the guest, the driver
reads from the host machine's /dev/random, in-turn reading from
the host kernel's entropy pool. This entropy pool could have been
filled by a hardware random number generator or just the host
kernel's internal software entropy generator.
Currently the driver does not fill the guests kernel entropy pool,
this requires a userspace tool running inside the guest (like
rng-tools) to read from the dummy device provided by this driver,
which then would fill the guest's internal entropy pool.
This all seems quite pointless when we are already reading from an
entropy pool, so this patch aims to register the device as a hwrng
device using the hwrng-core framework. This not only improves and
cleans up the driver, but also fills the guest's entropy pool
without having to resort to using extra userspace tools in the guest.
This is typically a nuisance when booting a guest: the random pool
takes a long time (~200s) to build up enough entropy since the dummy
hwrng is not used to fill the guest's pool.
This port was originally attempted by Alexander Neville "dark" (in CC,
discussion in Link), but the conversation there stalled since the
handling of -EAGAIN errors were no removed and longer handled by the
driver. This patch attempts to use the existing method of error
handling but utilises the new hwrng core.
The issue can be noticed when booting a UML guest:
[ 2.560000] random: fast init done
[ 214.000000] random: crng init done
With the patch applied, filling the pool becomes a lot quicker:
[ 2.560000] random: fast init done
[ 12.000000] random: crng init done

RISC-V Fixes for 5.10-rc6
I've collected a handful of fixes over the past few weeks:
* A fix to un-break the build-id argument to the vDSO build, which is necessary
for the LLVM linker.
* A fix to initialize the jump label subsystem, without which it (and all the
stuff that uses it) doesn't actually function.
* A fix to include <asm/barrier.h> from <vdso/processor.h>, without which some
drivers won't compile.
I know it's the holidays, but I had some hiccups getting this tested earlier
this week so it's just going out now. None of these are tremendously urgent,
so if they don't make rc6 it's not a big deal. I'll have some more fixes
coming next week either way.

perf tools for v5.10: 4th batch
- Fix die_entrypc() when DW_AT_ranges DWARF attribute not available.
- Cope with broken DWARF (missing DW_AT_declaration) generated by some recent
gcc versions.
- Do not generate CGROUP metadata events when not asked to in 'perf record'.
- Use proper CPU for shadow stats in 'perf stat'.
- Update copy of libbpf's hashmap.c, silencing tools/perf build warning.
- Fix return value in 'perf diff'.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

in particular fixing the MMC device ordering that
recently became nondeterministic with async probe.
- Multiple DT fixes for the Tegra platform, including
a regression fix for suspend/resume on TX2
- A regression fix for a user-triggered fault in the
NXP dpio driver
- A regression fix for a bug caused by an earlier bug
fix in the xilinx firmware driver
- Two more DTC warning fixes

Pull drm fixes from Dave Airlie:
"Unfortunately this has a bit of thanksgiving stuffing in it, as it a
bit larger (at least the vc4 patches) than I like at this point in
time.
The main thing is it has a bunch of regressions fixes for reports in
the last couple of weeks, ast, nouveau and the amdgpu ttm init fix,
along with the usual selection of amdgpu and i915 fixes.
The vc4 fixes are a few but they are fixes and the nastiest one is a
fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
that range and there isn't enough shielding and interference happen
between the two, the fix adjusts the mode clock to try and avoid the
wifi channels in that case.
Hopefully you can merge this between turkey slices, and next week
should be quieter.

A patch by me removes the hardcoded IRQF_TRIGGER_FALLING from the request_threaded_irq() as this clashes with the trigger level specified in the DT. Further a patch by me fixes the nominal bitiming tseg2 min value for modern m_can cores. Pankaj Sharma's patch add support for cores version 3.3.x. The last patch by Oliver Hartkopp is for af_can and converts a WARN() into a pr_warn(), which is triggered by the syzkaller.

mptcp: fix NULL ptr dereference on bad MPJ
If an msk listener receives an MPJ carrying an invalid token, it will zero the request socket msk entry. That should later cause fallback and subflow reset - as per RFC - at subflow_syn_recv_sock() time due to failing hmac validation. Since commit |

net: openvswitch: fix TTL decrement action netlink message format
Currently, the openvswitch module is not accepting the correctly formated
netlink message for the TTL decrement action. For both setting and getting
the dec_ttl action, the actions should be nested in the
OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi.
When the original patch was sent, it was tested with a private OVS userspace
implementation. This implementation was unfortunately not upstreamed and
reviewed, hence an erroneous version of this patch was sent out.
Leaving the patch as-is would cause problems as the kernel module could
interpret additional attributes as actions and vice-versa, due to the
actions not being encapsulated/nested within the actual attribute, but
being concatinated after it.
Fixes:
