9704669 Masami Hiramatsu (Google) 17 February 2024, 12:25:42 UTC tracing/probes: Fix to search structure fields correctly Fix to search a field from the structure which has anonymous union correctly. Since the reference `type` pointer was updated in the loop, the search loop suddenly aborted where it hits an anonymous union. Thus it can not find the field after the anonymous union. This avoids updating the cursor `type` pointer in the loop.

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. Selftests cleanups and fixes: - 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" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (25 commits) KVM: arm64: Fix double-free following kvm_pgtable_stage2_free_unlinked() RISC-V: KVM: Use correct restricted types RISC-V: paravirt: Use correct restricted types RISC-V: paravirt: steal_time should be static KVM: selftests: Don't assert on exact number of 4KiB in dirty log split test KVM: selftests: Fix a semaphore imbalance in the dirty ring logging test KVM: x86: Fix KVM_GET_MSRS stack info leak KVM: arm64: Do not source virt/lib/Kconfig twice KVM: x86/pmu: Fix type length error when reading pmu->fixed_ctr_ctrl KVM: x86: Make gtod_is_based_on_tsc() return 'bool' KVM: selftests: Make hyperv_clock require TSC based system clocksource KVM: selftests: Run clocksource dependent tests with hyperv_clocksource_tsc_page too KVM: selftests: Use generic sys_clocksource_is_tsc() in vmx_nested_tsc_scaling_test KVM: selftests: Generalize check_clocksource() from kvm_clock_test KVM: x86: make KVM_REQ_NMI request iff NMI pending for vcpu KVM: arm64: Fix circular locking dependency KVM: selftests: Fail tests when open() fails with !ENOENT KVM: selftests: Avoid infinite loop in hyperv_features when invtsc is missing KVM: selftests: Delete superfluous, unused "stage" variable in AMX test KVM: selftests: x86_64: Remove redundant newlines ... 16 February 2024, 18:48:14 UTC

But the ring buffer disable has several bits that disable it. One is internal disabling which is used for resizing and other modifications of the ring buffer. But the "tracing_on" user space visible flag should only report if tracing is actually on and not internally disabled, as this can cause confusion as writing "1" when it is disabled will not enable it. Instead use ring_buffer_record_is_set_on() which shows the user space visible settings. - Fix a false positive kmemleak on saved cmdlines Now that the saved_cmdlines structure is allocated via alloc_page() and not via kmalloc() it has become invisible to kmemleak.

4860abb Steve French 06 February 2024, 22:34:22 UTC smb: Fix regression in writes when non-standard maximum write size negotiated The conversion to netfs in the 6.3 kernel caused a regression when maximum write size is set by the server to an unexpected value which is not a multiple of 4096 (similarly if the user overrides the maximum write size by setting mount parm "wsize", but sets it to a value that is not a multiple of 4096). When negotiated write size is not a multiple of 4096 the netfs code can skip the end of the final page when doing large sequential writes, causing data corruption. This section of code is being rewritten/removed due to a large netfs change, but until that point (ie for the 6.3 kernel until now) we can not support non-standard maximum write sizes. Add a warning if a user specifies a wsize on mount that is not a multiple of 4096 (and round down), also add a change where we round down the maximum write size if the server negotiates a value that is not a multiple of 4096 (we also have to check to make sure that we do not round it down to zero).

14db5f6 Damien Le Moal 08 February 2024, 08:26:59 UTC zonefs: Improve error handling Write error handling is racy and can sometime lead to the error recovery path wrongly changing the inode size of a sequential zone file to an incorrect value which results in garbage data being readable at the end of a file. There are 2 problems: 1) zonefs_file_dio_write() updates a zone file write pointer offset after issuing a direct IO with iomap_dio_rw(). This update is done only if the IO succeed for synchronous direct writes. However, for asynchronous direct writes, the update is done without waiting for the IO completion so that the next asynchronous IO can be immediately issued. However, if an asynchronous IO completes with a failure right before the i_truncate_mutex lock protecting the update, the update may change the value of the inode write pointer offset that was corrected by the error path (zonefs_io_error() function). 2) zonefs_io_error() is called when a read or write error occurs. This function executes a report zone operation using the callback function zonefs_io_error_cb(), which does all the error recovery handling based on the current zone condition, write pointer position and according to the mount options being used. However, depending on the zoned device being used, a report zone callback may be executed in a context that is different from the context of __zonefs_io_error(). As a result, zonefs_io_error_cb() may be executed without the inode truncate mutex lock held, which can lead to invalid error processing. Fix both problems as follows: - Problem 1: Perform the inode write pointer offset update before a direct write is issued with iomap_dio_rw(). This is safe to do as partial direct writes are not supported (IOMAP_DIO_PARTIAL is not set) and any failed IO will trigger the execution of zonefs_io_error() which will correct the inode write pointer offset to reflect the current state of the one on the device. - Problem 2: Change zonefs_io_error_cb() into zonefs_handle_io_error() and call this function directly from __zonefs_io_error() after obtaining the zone information using blkdev_report_zones() with a simple callback function that copies to a local stack variable the struct blk_zone obtained from the device. This ensures that error handling is performed holding the inode truncate mutex. This change also simplifies error handling for conventional zone files by bypassing the execution of report zones entirely. This is safe to do because the condition of conventional zones cannot be read-only or offline and conventional zone files are always fully mapped with a constant file size.

68fb3ca Linus Torvalds 15 February 2024, 19:14:33 UTC update workarounds for gcc "asm goto" issue In commit 4356e9f841f7 ("work around gcc bugs with 'asm goto' with outputs") I did the gcc workaround unconditionally, because the cause of the bad code generation wasn't entirely clear. In the meantime, Jakub Jelinek debugged the issue, and has come up with a fix in gcc [2], which also got backported to the still maintained branches of gcc-11, gcc-12 and gcc-13. Note that while the fix technically wasn't in the original gcc-14 branch, Jakub says: "while it is true that no GCC 14 snapshots until today (or whenever the fix will be committed) have the fix, for GCC trunk it is up to the distros to use the latest snapshot if they use it at all and would allow better testing of the kernel code without the workaround, so that if there are other issues they won't be discovered years later. Most userland code doesn't actually use asm goto with outputs..." so we will consider gcc-14 to be fixed - if somebody is using gcc snapshots of the gcc-14 before the fix, they should upgrade. Note that while the bug goes back to gcc-11, in practice other gcc changes seem to have effectively hidden it since gcc-12.1 as per a bisect by Jakub. So even a gcc-14 snapshot without the fix likely doesn't show actual problems. Also, make the default 'asm_goto_output()' macro mark the asm as volatile by hand, because of an unrelated gcc issue [1] where it doesn't match the documented behavior ("asm goto is always volatile").

41c25e1 Takashi Iwai 15 February 2024, 15:31:44 UTC ALSA: usb-audio: More relaxed check of MIDI jack names The USB audio driver tries to retrieve MIDI jack name strings that can be used for rawmidi substream names and sequencer port names, but its checking is too strict: often the firmware provides the jack info for unexpected directions, and then we miss the info although it's present. In this patch, the code to extract the jack info is changed to allow both in and out directions in a single loop. That is, the former two functions to obtain the descriptor pointers for jack in and out are changed to a single function that returns iJack of the corresponding jack ID, no matter which direction is used. It's a code simplification at the same time as well as the fix.

As Doug observes it is not entirely surprising that such a large allocation of contiguous memory might fail on a long running system. The SVE regset is currently sized to hold SVE registers with a VQ of SVE_VQ_MAX which is 512, substantially more than the architectural maximum of 16 which we might see even in a system emulating the limits of the architecture. Since we don't expose the size we tell the regset core externally let's define ARCH_SVE_VQ_MAX with the actual architectural maximum and use that for the regset, we'll still overallocate most of the time but much less so which will be helpful even if the core is fixed to not require contiguous allocations. Specify ARCH_SVE_VQ_MAX in terms of the maximum value that can be written into ZCR_ELx.LEN (where this is set in the hardware). For consistency update the maximum SME vector length to be specified in the same style while we are at it. We could also teach the ptrace core about runtime discoverable regset sizes but that would be a more invasive change and this is being observed in practical systems.

This points to the second poll() in the test which is expected to wait for the sender to send the rest of the data. Apparently under some conditions that doesn't happen within 5ms, bump the timeout to 20ms.

dadd170 Dave Ertman 13 February 2024, 18:39:55 UTC ice: Add check for lport extraction to LAG init To fully support initializing the LAG support code, a DDP package that extracts the logical port from the metadata is required. If such a package is not present, there could be difficulties in supporting some bond types. Add a check into the initialization flow that will bypass the new paths if any of the support pieces are missing.
