[PATCH v2 0/5] docs: stable-kernel-rules: fine-tuning and 'no stable backport' tag

by Thorsten Leemhuis

After a recent discussion regarding "do we need a 'nobackport' tag" I set out to create one change for stable-kernel-rules.rst. This is now the last patch in the series, which links to that discussion with all the details; the other stuff is fine-tuning that happened along the way. Ciao, Thorsten --- v1->v2: * Add reviewed-by tag from Greg to the first patch. * Change the backport example in 2 as suggested by Greg. * Improve description of patch 3 while also making the change remove a level of indenting. * Add patch explaining stable(a)kernel.org (w/o @vger.) * Move the patch adding a 'make AUTOSEL et. al. ignore a change' flag to the end of the series and use stable+noautosel(a)kernel.org as suggested my Konstantin and ACKed by Greg. v1: https://lore.kernel.org/all/cover.1712812895.git.linux@leemhuis.info/ Thorsten Leemhuis (5): docs: stable-kernel-rules: reduce redundancy docs: stable-kernel-rules: call mainline by its name and change example docs: stable-kernel-rules: remove code-labels tags and a indention level docs: stable-kernel-rules: explain use of stable(a)kernel.org (w/o @vger.) docs: stable-kernel-rules: create special tag to flag 'no backporting' Documentation/process/stable-kernel-rules.rst | 234 ++++++++---------- 1 file changed, 110 insertions(+), 124 deletions(-) base-commit: 5eb4573ea63d0c83bf58fb7c243fc2c2b6966c02 -- 2.44.0

+ mm-fix-race-between-__split_huge_pmd_locked-and-gup-fast.patch added to mm-unstable branch

The patch titled Subject: mm: fix race between __split_huge_pmd_locked() and GUP-fast has been added to the -mm mm-unstable branch. Its filename is mm-fix-race-between-__split_huge_pmd_locked-and-gup-fast.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Ryan Roberts <ryan.roberts(a)arm.com> Subject: mm: fix race between __split_huge_pmd_locked() and GUP-fast Date: Wed, 1 May 2024 15:33:10 +0100 __split_huge_pmd_locked() can be called for a present THP, devmap or (non-present) migration entry. It calls pmdp_invalidate() unconditionally on the pmdp and only determines if it is present or not based on the returned old pmd. This is a problem for the migration entry case because pmd_mkinvalid(), called by pmdp_invalidate() must only be called for a present pmd. On arm64 at least, pmd_mkinvalid() will mark the pmd such that any future call to pmd_present() will return true. And therefore any lockless pgtable walker could see the migration entry pmd in this state and start interpretting the fields as if it were present, leading to BadThings (TM). GUP-fast appears to be one such lockless pgtable walker. x86 does not suffer the above problem, but instead pmd_mkinvalid() will corrupt the offset field of the swap entry within the swap pte. See link below for discussion of that problem. Fix all of this by only calling pmdp_invalidate() for a present pmd. And for good measure let's add a warning to all implementations of pmdp_invalidate[_ad](). I've manually reviewed all other pmdp_invalidate[_ad]() call sites and believe all others to be conformant. This is a theoretical bug found during code review. I don't have any test case to trigger it in practice.

[PATCH] drm/i915/audio: Fix audio time stamp programming for DP

by Chaitanya Kumar Borah

Intel hardware is capable of programming the Maud/Naud SDPs on its own based on real-time clocks. While doing so, it takes care of any deviations from the theoretical values. Programming the registers explicitly with static values can interfere with this logic. Therefore, let the HW decide the Maud and Naud SDPs on it's own.

[PATCH v2 1/5] tracefs: Reset permissions on remount if permissions are options

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> There's an inconsistency with the way permissions are handled in tracefs. Because the permissions are generated when accessed, they default to the root inode's permission if they were never set by the user. If the user sets the permissions, then a flag is set and the permissions are saved via the inode (for tracefs files) or an internal attribute field (for eventfs). But if a remount happens that specify the permissions, all the files that were not changed by the user gets updated, but the ones that were are not. If the user were to remount the file system with a given permission, then all files and directories within that file system should be updated. This can cause security issues if a file's permission was updated but the admin forgot about it. They could incorrectly think that remounting with permissions set would update all files, but miss some. For example: # cd /sys/kernel/tracing # chgrp 1002 current_tracer # ls -l [..] -rw-r----- 1 root root 0 May 1 21:25 buffer_size_kb -rw-r----- 1 root root 0 May 1 21:25 buffer_subbuf_size_kb -r--r----- 1 root root 0 May 1 21:25 buffer_total_size_kb -rw-r----- 1 root lkp 0 May 1 21:25 current_tracer -rw-r----- 1 root root 0 May 1 21:25 dynamic_events -r--r----- 1 root root 0 May 1 21:25 dyn_ftrace_total_info -r--r----- 1 root root 0 May 1 21:25 enabled_functions Where current_tracer now has group "lkp". # mount -o remount,gid=1001 . # ls -l -rw-r----- 1 root tracing 0 May 1 21:25 buffer_size_kb -rw-r----- 1 root tracing 0 May 1 21:25 buffer_subbuf_size_kb -r--r----- 1 root tracing 0 May 1 21:25 buffer_total_size_kb -rw-r----- 1 root lkp 0 May 1 21:25 current_tracer -rw-r----- 1 root tracing 0 May 1 21:25 dynamic_events -r--r----- 1 root tracing 0 May 1 21:25 dyn_ftrace_total_info -r--r----- 1 root tracing 0 May 1 21:25 enabled_functions Everything changed but the "current_tracer". Add a new link list that keeps track of all the tracefs_inodes which has the permission flags that tell if the file/dir should use the root inode's permission or not. Then on remount, clear all the flags so that the default behavior of using the root inode's permission is done for all files and directories.

[PATCH v2 5/5] eventfs: Have "events" directory get permissions from its parent

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> The events directory gets its permissions from the root inode. But this can cause an inconsistency if the instances directory changes its permissions, as the permissions of the created directories under it should inherit the permissions of the instances directory when directories under it are created. Currently the behavior is: # cd /sys/kernel/tracing # chgrp 1002 instances # mkdir instances/foo # ls -l instances/foo [..] -r--r----- 1 root lkp 0 May 1 18:55 buffer_total_size_kb -rw-r----- 1 root lkp 0 May 1 18:55 current_tracer -rw-r----- 1 root lkp 0 May 1 18:55 error_log drwxr-xr-x 1 root root 0 May 1 18:55 events --w------- 1 root lkp 0 May 1 18:55 free_buffer drwxr-x--- 2 root lkp 0 May 1 18:55 options drwxr-x--- 10 root lkp 0 May 1 18:55 per_cpu -rw-r----- 1 root lkp 0 May 1 18:55 set_event All the files and directories under "foo" has the "lkp" group except the "events" directory.

[PATCH v2 4/5] eventfs: Do not treat events directory different than other directories

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> Treat the events directory the same as other directories when it comes to permissions. The events directory was considered different because it's dentry is persistent, whereas the other directory dentries are created when accessed. But the way tracefs now does its ownership by using the root dentry's permissions as the default permissions, the events directory can get out of sync when a remount is performed setting the group and user permissions. Remove the special case for the events directory on setting the attributes. This allows the updates caused by remount to work properly as well as simplifies the code.

[PATCH v2 2/5] tracefs: Still use mount point as default permissions for instances

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> If the instances directory's permissions were never change, then have it and its children use the mount point permissions as the default. Currently, the permissions of instance directories are determined by the instance directory's permissions itself. But if the tracefs file system is remounted and changes the permissions, the instance directory and its children should use the new permission. But because both the instance directory and its children use the instance directory's inode for permissions, it misses the update. To demonstrate this: # cd /sys/kernel/tracing/ # mkdir instances/foo # ls -ld instances/foo drwxr-x--- 5 root root 0 May 1 19:07 instances/foo # ls -ld instances drwxr-x--- 3 root root 0 May 1 18:57 instances # ls -ld current_tracer -rw-r----- 1 root root 0 May 1 18:57 current_tracer # mount -o remount,gid=1002 . # ls -ld instances drwxr-x--- 3 root root 0 May 1 18:57 instances # ls -ld instances/foo/ drwxr-x--- 5 root root 0 May 1 19:07 instances/foo/ # ls -ld current_tracer -rw-r----- 1 root lkp 0 May 1 18:57 current_tracer Notice that changing the group id to that of "lkp" did not affect the instances directory nor its children. It should have been: # ls -ld current_tracer -rw-r----- 1 root root 0 May 1 19:19 current_tracer # ls -ld instances/foo/ drwxr-x--- 5 root root 0 May 1 19:25 instances/foo/ # ls -ld instances drwxr-x--- 3 root root 0 May 1 19:19 instances # mount -o remount,gid=1002 . # ls -ld current_tracer -rw-r----- 1 root lkp 0 May 1 19:19 current_tracer # ls -ld instances drwxr-x--- 3 root lkp 0 May 1 19:19 instances # ls -ld instances/foo/ drwxr-x--- 5 root lkp 0 May 1 19:25 instances/foo/ Where all files were updated by the remount gid update.
