by Huacai Chen

Update cpu_sibling_map when disabling nonboot CPUs by defining & calling clear_cpu_sibling_map(), otherwise we get such errors on SMT systems: jump label: negative count!

[REGRESSION 6.1.70] system calls with CIFS mounts failing with "Resource temporarily unavailable"

by Leonardo Brondani Schenkel

I'm new here, first time reporting a regression, apologies in advance if I'm doing something wrong of if this was already reported (I found some CIFS issues but not exactly this one). I'm using x86-64 Arch Linux and LTS kernel (6.1.71 as I write this) and I noticed a regression that I could reproduce in other boxes with other architectures as well (aarch64 with 6.1.70). # mount.cifs //server/share /mnt # mount //server/share on /mnt type cifs (rw,relatime,vers=3.1.1...) # cd /mnt # df . df: .: Resource temporarily unavailable # ls -al ls: .: Resource temporarily unavailable ls: file1: Resource temporarily unavailable ls: file2: Resource temporarily unavailable [...then ls shows the listing...] If I use strace with df, the problem is: statfs(".", 0x.....) = -1 EAGAIN (Resource temporarily unavailable) And with ls: listxattr(".", 0x..., 152): -1 EAGAIN (Resource temporarily unavailable) listxattr("file1", ..., 152): -1 EAGAIN (same as above) ... Initially I thought the problem was with the Samba server and/or the client mount flags, but I've spent a day trying a *lot* of different combinations and nothing worked. This happens with any share that I try, and I've tried mounting shares from multiple Linux boxes running different Samba and kernel versions. Then I tried changing kernel versions at my client box. I booted latest 6.6.9 and the problem simply disappeared. My Debian server with 6.5.11 also doesn't have it. I then started a VM and tried a "bisection" of 6.1.x versions, leading to kernel 6.1.70 when this started to happen. 6.1.69 and older look fine. I hope that this is enough information to reproduce this issue. I will be glad to provide more info if necessary. // Leonardo.

[PATCH v2] mm, mmap: fix vma_merge() case 7 with vma_ops->close

by Vlastimil Babka

When debugging issues with a workload using SysV shmem, Michal Hocko has come up with a reproducer that shows how a series of mprotect() operations can result in an elevated shm_nattch and thus leak of the resource. The problem is caused by wrong assumptions in vma_merge() commit 714965ca8252 ("mm/mmap: start distinguishing if vma can be removed in mergeability test"). The shmem vmas have a vma_ops->close callback that decrements shm_nattch, and we remove the vma without calling it. vma_merge() has thus historically avoided merging vma's with vma_ops->close and commit 714965ca8252 was supposed to keep it that way. It relaxed the checks for vma_ops->close in can_vma_merge_after() assuming that it is never called on a vma that would be a candidate for removal. However, the vma_merge() code does also use the result of this check in the decision to remove a different vma in the merge case 7. A robust solution would be to refactor vma_merge() code in a way that the vma_ops->close check is only done for vma's that are actually going to be removed, and not as part of the preliminary checks. That would both solve the existing bug, and also allow additional merges that the checks currently prevent unnecessarily in some cases. However to fix the existing bug first with a minimized risk, and for easier stable backports, this patch only adds a vma_ops->close check to the buggy case 7 specifically. All other cases of vma removal are covered by the can_vma_merge_before() check that includes the test for vma_ops->close. The reproducer code, adapted from Michal Hocko's code: int main(int argc, char *argv[]) { int segment_id; size_t segment_size = 20 * PAGE_SIZE; char * sh_mem; struct shmid_ds shmid_ds; key_t key = 0x1234; segment_id = shmget(key, segment_size, IPC_CREAT | IPC_EXCL | S_IRUSR | S_IWUSR); sh_mem = (char *)shmat(segment_id, NULL, 0); mprotect(sh_mem + 2*PAGE_SIZE, PAGE_SIZE, PROT_NONE); mprotect(sh_mem + PAGE_SIZE, PAGE_SIZE, PROT_WRITE); mprotect(sh_mem + 2*PAGE_SIZE, PAGE_SIZE, PROT_WRITE); shmdt(sh_mem); shmctl(segment_id, IPC_STAT, &shmid_ds); printf("nattch after shmdt(): %lu (expected: 0)\n", shmid_ds.shm_nattch); if (shmctl(segment_id, IPC_RMID, 0)) printf("IPCRM failed %d\n", errno); return (shmid_ds.shm_nattch) ? 1 : 0; } Fixes: 714965ca8252 ("mm/mmap: start distinguishing if vma can be removed in mergeability test") Signed-off-by: Vlastimil Babka <vbabka(a)suse.cz> Reported-by: Michal Hocko <mhocko(a)suse.com> Cc: Liam R.

[PATCH] ARM: imx_v6_v7_defconfig: Restore CONFIG_BACKLIGHT_CLASS_DEVICE

by Fabio Estevam

From: Fabio Estevam <festevam(a)denx.de> Since commit bfac19e239a7 ("fbdev: mx3fb: Remove the driver") backlight is no longer functional. The fbdev mx3fb driver used to automatically select CONFIG_BACKLIGHT_CLASS_DEVICE. Now that the mx3fb driver has been removed, enable the CONFIG_BACKLIGHT_CLASS_DEVICE option so that backlight can still work by default. Tested on a imx6dl-sabresd board.

However the length of the file handle must be a multiple of 4 so the file handle is actually 12 bytes long and the last two bytes remain uninitialized. This is not great at we potentially leak uninitialized information with the handle to userspace. Properly initialize the full handle length.

Use bits_per() instead, which rounds up. Found by code inspection. The effect of this would probably be a misaccounting when doing NUMA balancing, so to a user, it would only be a performance penalty. The effects may be more wide-spread; it's hard to tell.

[PATCH 0/2] Disable automatic load CCS load balancing

by Andi Shyti

Hi, this series does basically two things: 1. Disables automatic load balancing as adviced by the hardware workaround. 2. Assigns all the CCS slices to one single user engine. The user will then be able to query only one CCS engine Changelog ========= - In Patch 1 use the correct workaround number (thanks Matt). - In Patch 2 do not add the extra CCS engines to the exposed UABI engine list and adapt the engine counting accordingly (thanks Tvrtko). - Reword the commit of Patch 2 (thanks John).
