[PATCH v3 02/11] platform/x86/intel/pmt: crashlog binary file endpoint

by Michael J. Ruhl

Usage of the intel_pmt_read() for binary sysfs, requires an allocated endpoint struct. The crashlog driver does not allocate the endpoint. Without the ep, the crashlog usage causes the following NULL pointer exception: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: Oops: 0000 [#1] SMP NOPTI RIP: 0010:intel_pmt_read+0x3b/0x70 [pmt_class] Code: Call Trace: <TASK> ? sysfs_kf_bin_read+0xc0/0xe0 kernfs_fop_read_iter+0xac/0x1a0 vfs_read+0x26d/0x350 ksys_read+0x6b/0xe0 __x64_sys_read+0x1d/0x30 x64_sys_call+0x1bc8/0x1d70 do_syscall_64+0x6d/0x110 Add the endpoint information to the crashlog driver to avoid the NULL pointer exception.

[PATCH RESEND 3/3] HID: wacom: fix kobject reference count leak

by Qasim Ijaz

When sysfs_create_files() fails in wacom_initialize_remotes() the error is returned and the cleanup action will not have been registered yet. As a result the kobject��s refcount is never dropped, so the kobject can never be freed leading to a reference leak. Fix this by calling kobject_put() before returning.

[PATCH RESEND 1/3] HID: wacom: fix memory leak on kobject creation failure

by Qasim Ijaz

During wacom_initialize_remotes() a fifo buffer is allocated with kfifo_alloc() and later a cleanup action is registered during devm_add_action_or_reset() to clean it up. However if the code fails to create a kobject and register it with sysfs the code simply returns -ENOMEM before the cleanup action is registered leading to a memory leak. Fix this by ensuring the fifo is freed when the kobject creation and registration process fails.

[PATCH 6.15.y] pinctrl: mediatek: eint: Fix invalid pointer dereference for v1 platforms

by Uwe Kleine-König

From: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> commit 1c9977b263475373b31bbf86af94a5c9ae2be42c upstream. Commit 3ef9f710efcb ("pinctrl: mediatek: Add EINT support for multiple addresses") introduced an access to the 'soc' field of struct mtk_pinctrl in mtk_eint_do_init() and for that an include of pinctrl-mtk-common-v2.h. However, pinctrl drivers relying on the v1 common driver include pinctrl-mtk-common.h instead, which provides another definition of struct mtk_pinctrl that does not contain an 'soc' field. Since mtk_eint_do_init() can be called both by v1 and v2 drivers, it will now try to dereference an invalid pointer when called on v1 platforms. This has been observed on Genio 350 EVK (MT8365), which crashes very early in boot (the kernel trace can only be seen with earlycon). In order to fix this, since 'struct mtk_pinctrl' was only needed to get a 'struct mtk_eint_pin', make 'struct mtk_eint_pin' a parameter of mtk_eint_do_init() so that callers need to supply it, removing mtk_eint_do_init()'s dependency on any particular 'struct mtk_pinctrl'.

[for-linus][PATCH 1/3] tracing: Fix regression of filter waiting a long time on RCU synchronization

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> When faultable trace events were added, a trace event may no longer use normal RCU to synchronize but instead used synchronize_rcu_tasks_trace(). This synchronization takes a much longer time to synchronize. The filter logic would free the filters by calling tracepoint_synchronize_unregister() after it unhooked the filter strings and before freeing them. With this function now calling synchronize_rcu_tasks_trace() this increased the time to free a filter tremendously. On a PREEMPT_RT system, it was even more noticeable. # time trace-cmd record -p function sleep 1 [..] real 2m29.052s user 0m0.244s sys 0m20.136s As trace-cmd would clear out all the filters before recording, it could take up to 2 minutes to do a recording of "sleep 1". To find out where the issues was: ~# trace-cmd sqlhist -e -n sched_stack select start.prev_state as state, end.next_comm as comm, TIMESTAMP_DELTA_USECS as delta, start.STACKTRACE as stack from sched_switch as start join sched_switch as end on start.prev_pid = end.next_pid Which will produce the following commands (and -e will also execute them): echo 's:sched_stack s64 state; char comm[16]; u64 delta; unsigned long stack[];' >> /sys/kernel/tracing/dynamic_events echo 'hist:keys=prev_pid:__arg_18057_2=prev_state,__arg_18057_4=common_timestamp.usecs,__arg_18057_7=common_stacktrace' >> /sys/kernel/tracing/events/sched/sched_switch/trigger echo 'hist:keys=next_pid:__state_18057_1=$__arg_18057_2,__comm_18057_3=next_comm,__delta_18057_5=common_timestamp.usecs-$__arg_18057_4,__stack_18057_6=$__arg_18057_7:onmatch(sched.sched_switch).trace(sched_stack,$__state_18057_1,$__comm_18057_3,$__delta_18057_5,$__stack_18057_6)' >> /sys/kernel/tracing/events/sched/sched_switch/trigger The above creates a synthetic event that creates a stack trace when a task schedules out and records it with the time it scheduled back in. Basically the time a task is off the CPU. It also records the state of the task when it left the CPU (running, blocked, sleeping, etc). It also saves the comm of the task as "comm" (needed for the next command). ~# echo 'hist:keys=state,stack.stacktrace:vals=delta:sort=state,delta if comm == "trace-cmd" && state & 3' > /sys/kernel/tracing/events/synthetic/sched_stack/trigger The above creates a histogram with buckets per state, per stack, and the value of the total time it was off the CPU for that stack trace. It filters on tasks with "comm == trace-cmd" and only the sleeping and blocked states (1 - sleeping, 2 - blocked). ~# trace-cmd record -p function sleep 1 ~# cat /sys/kernel/tracing/events/synthetic/sched_stack/hist | tail -18 { state: 2, stack.stacktrace __schedule+0x1545/0x3700 schedule+0xe2/0x390 schedule_timeout+0x175/0x200 wait_for_completion_state+0x294/0x440 __wait_rcu_gp+0x247/0x4f0 synchronize_rcu_tasks_generic+0x151/0x230 apply_subsystem_event_filter+0xa2b/0x1300 subsystem_filter_write+0x67/0xc0 vfs_write+0x1e2/0xeb0 ksys_write+0xff/0x1d0 do_syscall_64+0x7b/0x420 entry_SYSCALL_64_after_hwframe+0x76/0x7e } hitcount: 237 delta: 99756288 <<--------------- Delta is 99 seconds! Totals: Hits: 525 Entries: 21 Dropped: 0 This shows that this particular trace waited for 99 seconds on synchronize_rcu_tasks() in apply_subsystem_event_filter(). In fact, there's a lot of places in the filter code that spends a lot of time waiting for synchronize_rcu_tasks_trace() in order to free the filters. Add helper functions that will use call_rcu*() variants to asynchronously free the filters. This brings the timings back to normal: # time trace-cmd record -p function sleep 1 [..] real 0m14.681s user 0m0.335s sys 0m28.616s And the histogram also shows this: ~# cat /sys/kernel/tracing/events/synthetic/sched_stack/hist | tail -21 { state: 2, stack.stacktrace __schedule+0x1545/0x3700 schedule+0xe2/0x390 schedule_timeout+0x175/0x200 wait_for_completion_state+0x294/0x440 __wait_rcu_gp+0x247/0x4f0 synchronize_rcu_normal+0x3db/0x5c0 tracing_reset_online_cpus+0x8f/0x1e0 tracing_open+0x335/0x440 do_dentry_open+0x4c6/0x17a0 vfs_open+0x82/0x360 path_openat+0x1a36/0x2990 do_filp_open+0x1c5/0x420 do_sys_openat2+0xed/0x180 __x64_sys_openat+0x108/0x1d0 do_syscall_64+0x7b/0x420 } hitcount: 2 delta: 77044 Totals: Hits: 55 Entries: 28 Dropped: 0 Where the total waiting time of synchronize_rcu_tasks_trace() is 77 milliseconds.

[PATCH 0/2] mm/memory: fix memory tearing on threaded fork

by Jann Horn

The first patch is a fix with an explanation of the issue, you should read that first. The second patch adds a comment to document the rules because figuring this out from scratch causes brain pain. Accidentally hitting this issue and getting negative consequences from it would require several stars to line up just right; but if someone out there is using a malloc() implementation that uses lockless data structures across threads or such, this could actually be a problem. In case someone wants a testcase, here's a very artificial one: ``` #include <pthread.h> #include <err.h> #include <stdio.h> #include <unistd.h> #include <sys/syscall.h> #include <sys/uio.h> #include <sys/mman.h> #include <sys/wait.h> #include <linux/io_uring.h> #define SYSCHK(x) ({ \ typeof(x) __res = (x); \ if (__res == (typeof(x))-1) \ err(1, "SYSCHK(" #x ")"); \ __res; \ }) #define NUM_SQ_PAGES 4 static int uring_init(struct io_uring_sqe **sqesp, void **cqesp) { struct io_uring_sqe *sqes = SYSCHK(mmap(NULL, NUM_SQ_PAGES*0x1000, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, -1, 0)); void *cqes = SYSCHK(mmap(NULL, NUM_SQ_PAGES*0x1000, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, -1, 0)); *(volatile unsigned int *)(cqes+4) = 64 * NUM_SQ_PAGES; struct io_uring_params params = { .flags = IORING_SETUP_NO_MMAP|IORING_SETUP_NO_SQARRAY, .sq_off = { .user_addr = (unsigned long)sqes }, .cq_off = { .user_addr = (unsigned long)cqes } }; int uring_fd = SYSCHK(syscall(__NR_io_uring_setup, /*entries=*/10, &params)); if (sqesp) *sqesp = sqes; if (cqesp) *cqesp = cqes; return uring_fd; } static char *bufmem[0x3000] __attribute__((aligned(0x1000))); static void *thread_fn(void *dummy) { unsigned long i = 0; while (1) { *(volatile unsigned long *)(bufmem + 0x0000) = i; *(volatile unsigned long *)(bufmem + 0x0f00) = i; *(volatile unsigned long *)(bufmem + 0x1000) = i; *(volatile unsigned long *)(bufmem + 0x1f00) = i; *(volatile unsigned long *)(bufmem + 0x2000) = i; *(volatile unsigned long *)(bufmem + 0x2f00) = i; i++; } } int main(void) { #if 1 int uring_fd = uring_init(NULL, NULL); struct iovec reg_iov = { .iov_base = bufmem, .iov_len = 0x2000 }; SYSCHK(syscall(__NR_io_uring_register, uring_fd, IORING_REGISTER_BUFFERS, &reg_iov, 1)); #endif pthread_t thread; if (pthread_create(&thread, NULL, thread_fn, NULL)) errx(1, "pthread_create"); sleep(1); int child = SYSCHK(fork()); if (child == 0) { printf("bufmem values:\n"); printf(" 0x0000: 0x%lx\n", *(volatile unsigned long *)(bufmem + 0x0000)); printf(" 0x0f00: 0x%lx\n", *(volatile unsigned long *)(bufmem + 0x0f00)); printf(" 0x1000: 0x%lx\n", *(volatile unsigned long *)(bufmem + 0x1000)); printf(" 0x1f00: 0x%lx\n", *(volatile unsigned long *)(bufmem + 0x1f00)); printf(" 0x2000: 0x%lx\n", *(volatile unsigned long *)(bufmem + 0x2000)); printf(" 0x2f00: 0x%lx\n", *(volatile unsigned long *)(bufmem + 0x2f00)); return 0; } int wstatus; SYSCHK(wait(&wstatus)); return 0; } ``` Without this series, the child will usually print results that are apart by more than 1, which is not a state that ever occurred in the parent; in my opinion, that counts as a bug. If you change the "#if 1" to "#if 0", the bug won't manifest.

[PATCH AUTOSEL 5.4 1/3] cifs: Fix cifs_query_path_info() for Windows NT servers

by Sasha Levin

From: Pali Rohár <pali(a)kernel.org> [ Upstream commit a3e771afbb3bce91c8296828304903e7348003fe ] For TRANS2 QUERY_PATH_INFO request when the path does not exist, the Windows NT SMB server returns error response STATUS_OBJECT_NAME_NOT_FOUND or ERRDOS/ERRbadfile without the SMBFLG_RESPONSE flag set. Similarly it returns STATUS_DELETE_PENDING when the file is being deleted. And looks like that any error response from TRANS2 QUERY_PATH_INFO does not have SMBFLG_RESPONSE flag set. So relax check in check_smb_hdr() for detecting if the packet is response for this special case. This change fixes stat() operation against Windows NT SMB servers and also all operations which depends on -ENOENT result from stat like creat() or mkdir(). Signed-off-by: Pali Rohár <pali(a)kernel.org> Signed-off-by: Steve French <stfrench(a)microsoft.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES** This commit should be backported to stable kernel trees. Here's my extensive analysis: ## Backport Recommendation: YES ### Nature of the Fix This is a **targeted bug fix** that addresses a specific protocol compliance issue with Windows NT SMB servers. The commit fixes a fundamental problem where basic file operations (`stat()`, `creat()`, `mkdir()`) fail against Windows NT servers due to overly strict SMB header validation. ### Code Change Analysis The fix is remarkably **simple and contained** - only 8 lines of code in a single function: ```c /bin /bin.usr-is-merged /boot /dev /etc /home /init /lib /lib.usr- is-merged /lib64 /lost+found /media /mnt /opt /proc /root /run /sbin /sbin.usr-is-merged /snap /srv /sys /tmp /usr /var * Windows NT server returns error resposne (e.g. STATUS_DELETE_PENDING * or STATUS_OBJECT_NAME_NOT_FOUND or ERRDOS/ERRbadfile or any other) * for some TRANS2 requests without the RESPONSE flag set in header. */ if (smb->Command == SMB_COM_TRANSACTION2 && smb->Status.CifsError != 0) return 0; ``` The change is in the `check_smb_hdr()` function in `fs/smb/client/misc.c`, which validates SMB packet headers. The fix **relaxes validation** only for a very specific case: TRANS2 commands returning errors from Windows NT servers. ### Risk Assessment: LOW 1. **Surgical precision**: Only affects SMB1 TRANS2 error responses, leaving normal operation paths untouched 2. **Conservative approach**: The condition `smb->Status.CifsError != 0` ensures this only applies to actual error responses 3. **No behavioral changes** for compliant servers that properly set the RESPONSE flag 4. **Well-established code path**: The `check_smb_hdr()` function is mature and stable ### Impact Assessment: HIGH 1. **Fixes broken functionality**: Without this fix, basic file operations fail completely against Windows NT servers 2. **Backward compatibility**: Restores support for legacy but still-used server environments 3. **User-visible improvement**: Directly fixes `stat()`, `creat()`, and `mkdir()` operations 4. **No regressions**: Modern SMB servers continue to work as before ### Comparison with Similar Commits Looking at the provided similar commits: - **Similar Commit #2** (Status: YES): Also adds new status code mappings for better server compatibility - **Similar Commit #3** (Status: YES): Reduces unnecessary network roundtrips by improving error handling - **Similar Commit #4** (Status: YES): Fixes WSL reparse point querying over SMB1 - **Similar Commit #5** (Status: YES): Fixes missing resource cleanup This commit follows the **same pattern** as these approved backports: small, targeted fixes that improve compatibility and fix real-world issues without introducing new features or architectural changes. ### Technical Justification The Windows NT server behavior described in the commit is **non-compliant but real**: these servers return error responses for TRANS2 QUERY_PATH_INFO requests without setting the `SMBFLG_RESPONSE` flag. The current strict validation incorrectly treats these as invalid packets, causing the CIFS client to fail when it should handle the errors properly. The fix is **protocol-aware** and **conservative** - it only relaxes validation for the specific case where we know Windows NT behaves differently, ensuring no impact on standard-compliant servers. ### Stable Tree Suitability This commit perfectly fits stable tree criteria: - ✅ **Important bug fix** affecting real-world usage - ✅ **Minimal and contained** change with clear scope - ✅ **No new features** - purely fixes existing broken functionality - ✅ **Low regression risk** due to targeted nature - ✅ **Production-ready** code following established patterns This should be backported to all stable kernels that support SMB1 client functionality, as it fixes a fundamental compatibility issue without any meaningful risk of regression. fs/cifs/misc.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/fs/cifs/misc.c b/fs/cifs/misc.c index db1fcdedf289a..af9752535dbab 100644 --- a/fs/cifs/misc.c +++ b/fs/cifs/misc.c @@ -306,6 +306,14 @@ check_smb_hdr(struct smb_hdr *smb) if (smb->Command == SMB_COM_LOCKING_ANDX) return 0; + /* + * Windows NT server returns error resposne (e.g. STATUS_DELETE_PENDING + * or STATUS_OBJECT_NAME_NOT_FOUND or ERRDOS/ERRbadfile or any other) + * for some TRANS2 requests without the RESPONSE flag set in header. + */ + if (smb->Command == SMB_COM_TRANSACTION2 && smb->Status.CifsError != 0) + return 0; + cifs_dbg(VFS, "Server sent request, not response. mid=%u\n", get_mid(smb)); return 1; -- 2.39.5
