KVM: x86/mmu: Retry fault before acquiring mmu_lock if mapping is changing
Retry page faults without acquiring mmu_lock, and without even faulting the page into the primary MMU, if the resolved gfn is covered by an active invalidation. Contending for mmu_lock is especially problematic on preemptible kernels as the mmu_notifier invalidation task will yield mmu_lock (see rwlock_needbreak()), delay the in-progress invalidation, and ultimately increase the latency of resolving the page fault. And in the worst case scenario, yielding will be accompanied by a remote TLB flush, e.g. if the invalidation covers a large range of memory and vCPUs are accessing addresses that were already zapped. Faulting the page into the primary MMU is similarly problematic, as doing so may acquire locks that need to be taken for the invalidation to complete (the primary MMU has finer grained locks than KVM's MMU), and/or may cause unnecessary churn (getting/putting pages, marking them accessed, etc). Alternatively, the yielding issue could be mitigated by teaching KVM's MMU iterators to perform more work before yielding, but that wouldn't solve the lock contention and would negatively affect scenarios where a vCPU is trying to fault in an address that is NOT covered by the in-progress invalidation. Add a dedicated lockess version of the range-based retry check to avoid false positives on the sanity check on start+end WARN, and so that it's super obvious that checking for a racing invalidation without holding mmu_lock is unsafe (though obviously useful). Wrap mmu_invalidate_in_progress in READ_ONCE() to ensure that pre-checking invalidation in a loop won't put KVM into an infinite loop, e.g. due to caching the in-progress flag and never seeing it go to '0'. Force a load of mmu_invalidate_seq as well, even though it isn't strictly necessary to avoid an infinite loop, as doing so improves the probability that KVM will detect an invalidation that already completed before acquiring mmu_lock and bailing anyways. Do the pre-check even for non-preemptible kernels, as waiting to detect the invalidation until mmu_lock is held guarantees the vCPU will observe the worst case latency in terms of handling the fault, and can generate even more mmu_lock contention. E.g. the vCPU will acquire mmu_lock, detect retry, drop mmu_lock, re-enter the guest, retake the fault, and eventually re-acquire mmu_lock. This behavior is also why there are no new starvation issues due to losing the fairness guarantees provided by rwlocks: if the vCPU needs to retry, it _must_ drop mmu_lock, i.e. waiting on mmu_lock doesn't guarantee forward progress in the face of _another_ mmu_notifier invalidation event. Note, adding READ_ONCE() isn't entirely free, e.g. on x86, the READ_ONCE() may generate a load into a register instead of doing a direct comparison (MOV+TEST+Jcc instead of CMP+Jcc), but practically speaking the added cost is a few bytes of code and maaaaybe a cycle or three.

KVM: x86: Mark target gfn of emulated atomic instruction as dirty
When emulating an atomic access on behalf of the guest, mark the target
gfn dirty if the CMPXCHG by KVM is attempted and doesn't fault. This
fixes a bug where KVM effectively corrupts guest memory during live
migration by writing to guest memory without informing userspace that the
page is dirty.
Marking the page dirty got unintentionally dropped when KVM's emulated
CMPXCHG was converted to do a user access. Before that, KVM explicitly
mapped the guest page into kernel memory, and marked the page dirty during
the unmap phase.
Mark the page dirty even if the CMPXCHG fails, as the old data is written
back on failure, i.e. the page is still written. The value written is
guaranteed to be the same because the operation is atomic, but KVM's ABI
is that all writes are dirty logged regardless of the value written. And
more importantly, that's what KVM did before the buggy commit.
Huge kudos to the folks on the Cc list (and many others), who did all the
actual work of triaging and debugging.

KVM selftests fixes/cleanups (and one KVM x86 cleanup) for 6.8:
- Remove redundant newlines from error messages.
- Delete an unused variable in the AMX test (which causes build failures when
compiling with -Werror).
- Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an
error code other than ENOENT (a Hyper-V selftest bug resulted in an EMFILE,
and the test eventually got skipped).
- Fix TSC related bugs in several Hyper-V selftests.
- Fix a bug in the dirty ring logging test where a sem_post() could be left
pending across multiple runs, resulting in incorrect synchronization between
the main thread and the vCPU worker thread.
- Relax the dirty log split test's assertions on 4KiB mappings to fix false
positives due to the number of mappings for memslot 0 (used for code and
data that is NOT being dirty logged) changing, e.g. due to NUMA balancing.
- Have KVM's gtod_is_based_on_tsc() return "bool" instead of an "int" (the
function generates boolean values, and all callers treat the return value as
a bool).

KVM x86 fixes for 6.8:
- Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only
if the incoming events->nmi.pending is non-zero. If the target vCPU is in
the UNITIALIZED state, the spurious request will result in KVM exiting to
userspace, which in turn causes QEMU to constantly acquire and release
QEMU's global mutex, to the point where the BSP is unable to make forward
progress.
- Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being
incorrectly truncated, and ultimately causes KVM to think a fixed counter
has already been disabled (KVM thinks the old value is '0').
- Fix a stack leak in KVM_GET_MSRS where a failed MSR read from userspace
that is ultimately ignored due to ignore_msrs=true doesn't zero the output
as intended.

firewire-fixes-6.8-rc4
This pull request includes the change to accelerate the device detection step in some cases. In the self-identification step after bus-reset, all of nodes in the same bus broadcast selfID packet including the value of gap count. The value is related to the cable hops between nodes, and used to calculate the subaction gap and the arbitration reset gap. When each node has the different value of the gap count, the asynchronous communication between them is unreliable, since an asynchronous transaction could be interrupted by another asynchronous transaction before completion. The gap count inconsistency can be resolved by several ways; e.g. the transfer of PHY configuration packet and generation of bus-reset. Current implementation of firewire stack can correctly detect the gap count inconsistency, however the recovery action from the inconsistency tends to be delayed after reading configuration ROM of root node. This results in the long time to probe devices in some combinations of hardware. In the pull request, the stack is changed to schedule the action immediately as possible. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQQE66IEYNDXNBPeGKSsLtaWM8LwEwUCZcdgUwAKCRCsLtaWM8Lw E8m+AQC9UnqCusCYwusAz/yVEiOjW+kHIxv7it3y3U3cRqCUFgEA7B7HsF3X2lNm k/geQajr0tOIGLl0MJRI3yNVsUtG9Q4= =p3Jg -----END PGP SIGNATURE----- Merge tag 'firewire-fixes-6.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fix from Takashi Sakamoto: "A change to accelerate the device detection step in some cases.

smb3: clarify mount warning
When a user tries to use the "sec=krb5p" mount parameter to encrypt
data on connection to a server (when authenticating with Kerberos), we
indicate that it is not supported, but do not note the equivalent
recommended mount parameter ("sec=krb5,seal") which turns on encryption
for that mount (and uses Kerberos for auth). Update the warning message.

Tracing fixes for v6.8-rc3:
- Fix broken direct trampolines being called when another callback is attached the same function. ARM 64 does not support FTRACE_WITH_REGS, and when it added direct trampoline calls from ftrace, it removed the "WITH_REGS" flag from the ftrace_ops for direct trampolines. This broke x86 as x86 requires direct trampolines to have WITH_REGS. This wasn't noticed because direct trampolines work as long as the function it is attached to is not shared with other callbacks (like the function tracer). When there's other callbacks, a helper trampoline is called, to call all the non direct callbacks and when it returns, the direct trampoline is called. For x86, the direct trampoline sets a flag in the regs field to tell the x86 specific code to call the direct trampoline. But this only works if the ftrace_ops had WITH_REGS set. ARM does things differently that does not require this. For now, set WITH_REGS if the arch supports WITH_REGS (which ARM does not), and this makes it work for both ARM64 and x86. - Fix wasted memory in the saved_cmdlines logic. The saved_cmdlines is a cache that maps PIDs to COMMs that tracing can use. Most trace events only save the PID in the event. The saved_cmdlines file lists PIDs to COMMs so that the tracing tools can show an actual name and not just a PID for each event. There's an array of PIDs that map to a small set of saved COMM strings. The array is set to PID_MAX_DEFAULT which is usually set to 32768. When a PID comes in, it will add itself to this array along with the index into the COMM array (note if the system allows more than PID_MAX_DEFAULT, this cache is similar to cache lines as an update of a PID that has the same PID_MAX_DEFAULT bits set will flush out another task with the same matching bits set). A while ago, the size of this cache was changed to be dynamic and the array was moved into a structure and created with kmalloc(). But this new structure had the size of 131104 bytes, or 0x20020 in hex. As kmalloc allocates in powers of two, it was actually allocating 0x40000 bytes (262144) leaving 131040 bytes of wasted memory. The last element of this structure was a pointer to the COMM string array which defaulted to just saving 128 COMMs. By changing the last field of this structure to a variable length string, and just having it round up to fill the allocated memory, the default size of the saved COMM cache is now 8190. This not only uses the wasted space, but actually saves space by removing the extra allocation for the COMM names. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZcYi8RQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqENAQD6xGE9EPkbHArElKfgpSuQOfGhcyyP LjgVhqVgmIoqUwD8CeVpxk3VwZIOQYvPn5XictcZgkYSeEWUZcKYg4c/3gs= =iIBv -----END PGP SIGNATURE----- Merge tag 'trace-v6.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix broken direct trampolines being called when another callback is attached the same function.

The saved_cmdlines is a cache that maps PIDs to COMMs that tracing can use. Most trace events only save the PID in the event. The saved_cmdlines file lists PIDs to COMMs so that the tracing tools can show an actual name and not just a PID for each event. There's an array of PIDs that map to a small set of saved COMM strings. The array is set to PID_MAX_DEFAULT which is usually set to 32768. When a PID comes in, it will add itself to this array along with the index into the COMM array (note if the system allows more than PID_MAX_DEFAULT, this cache is similar to cache lines as an update of a PID that has the same PID_MAX_DEFAULT bits set will flush out another task with the same matching bits set). A while ago, the size of this cache was changed to be dynamic and the array was moved into a structure and created with kmalloc(). But this new structure had the size of 131104 bytes, or 0x20020 in hex. As kmalloc allocates in powers of two, it was actually allocating 0x40000 bytes (262144) leaving 131040 bytes of wasted memory. The last element of this structure was a pointer to the COMM string array which defaulted to just saving 128 COMMs. By changing the last field of this structure to a variable length string, and just having it round up to fill the allocated memory, the default size of the saved COMM cache is now 8190. This not only uses the wasted space, but actually saves space by removing the extra allocation for the COMM names. * tag 'trace-v6.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix wasted memory in saved_cmdlines logic ftrace: Fix DIRECT_CALLS to use SAVE_REGS by default |

Probes fixes for v6.8-rc3:
- kprobes: Remove unnecessary initial values of local variables.
- tracing/probe-events: Fixing parser bugs.
. Fix to calculate the argument size and format string after setting
type information from BTF, because BTF can change the size and format
string.
. Fix to show $comm parse error correctly instead of failing silently.

"The only notable change here is the patch that changes the way we deal
with spurious errors from the EFI memory attribute protocol. This will
be backported to v6.6, and is intended to ensure that we will not
paint ourselves into a corner when we tighten this further in order to
comply with MS requirements on signed EFI code.
Note that this protocol does not currently exist in x86 production
systems in the field, only in Microsoft's fork of OVMF, but it will be
mandatory for Windows logo certification for x86 PCs in the future.

x86/Kconfig: Transmeta Crusoe is CPU family 5, not 6
The kernel built with MCRUSOE is unbootable on Transmeta Crusoe. It shows
the following error message:
This kernel requires an i686 CPU, but only detected an i586 CPU.
Unable to boot - please use a kernel appropriate for your CPU.
Remove MCRUSOE from the condition introduced in commit in Fixes, effectively
changing X86_MINIMUM_CPU_FAMILY back to 5 on that machine, which matches the
CPU family given by CPUID.

tracing: Fix wasted memory in saved_cmdlines logic
While looking at improving the saved_cmdlines cache I found a huge amount
of wasted memory that should be used for the cmdlines.
The tracing data saves pids during the trace. At sched switch, if a trace
occurred, it will save the comm of the task that did the trace. This is
saved in a "cache" that maps pids to comms and exposed to user space via
the /sys/kernel/tracing/saved_cmdlines file. Currently it only caches by
default 128 comms.
The structure that uses this creates an array to store the pids using
PID_MAX_DEFAULT (which is usually set to 32768). This causes the structure
to be of the size of 131104 bytes on 64 bit machines.
In hex: 131104 = 0x20020, and since the kernel allocates generic memory in
powers of two, the kernel would allocate 0x40000 or 262144 bytes to store
this structure. That leaves 131040 bytes of wasted space.
Worse, the structure points to an allocated array to store the comm names,
which is 16 bytes times the amount of names to save (currently 128), which
is 2048 bytes. Instead of allocating a separate array, make the structure
end with a variable length string and use the extra space for that.
This is similar to a recommendation that Linus had made about eventfs_inode names:
https://lore.kernel.org/all/20240130190355.11486-5-torvalds@linux-foundation.org/
Instead of allocating a separate string array to hold the saved comms,
have the structure end with: char saved_cmdlines[]; and round up to the
next power of two over sizeof(struct saved_cmdline_buffers) + num_cmdlines * TASK_COMM_LEN
It will use this extra space for the saved_cmdline portion.
Now, instead of saving only 128 comms by default, by using this wasted
space at the end of the structure it can save over 8000 comms and even
saves space by removing the need for allocating the other array.

virtio-blk: Ensure no requests in virtqueues before deleting vqs.
Ensure no remaining requests in virtqueues before resetting vdev and deleting virtqueues. Otherwise these requests will never be completed. It may cause the system to become unresponsive. Function blk_mq_quiesce_queue() can ensure that requests have become in_flight status, but it cannot guarantee that requests have been processed by the device. Virtqueues should never be deleted before all requests become complete status. Function blk_mq_freeze_queue() ensure that all requests in virtqueues become complete status.

blk-iocost: Fix an UBSAN shift-out-of-bounds warning
When iocg_kick_delay() is called from a CPU different than the one which set
the delay, @now may be in the past of @iocg->delay_at leading to the
following warning:
UBSAN: shift-out-of-bounds in block/blk-iocost.c:1359:23
shift exponent 18446744073709 is too large for 64-bit type 'u64' (aka 'unsigned long long')
...
Call Trace:
<TASK>

The underflow itself doesn't really affect the behavior in any meaningful
way; however, the past timestamp may exaggerate the delay amount calculated
later in the code, which shouldn't be a material problem given the nature of
the delay mechanism.
If @now is in the past, this CPU is racing another CPU which recently set up
the delay and there's nothing this CPU can contribute w.r.t. the delay.
Let's bail early from iocg_kick_delay() in such cases.
