[PATCH v2 0/2] drm/msm/dpu: two fixes targeting 6.11

by Dmitry Baryshkov

Leonard Lausen reported an issue with suspend/resume of the sc7180 devices. Fix the WB atomic check, which caused the issue. Also make sure that DPU debugging logs are always directed to the drm_debug / DRIVER so that usual drm.debug masks work in an expected way.

drm/amd/display: Pass pwrseq inst for backlight and ABM

by Alex Deucher

Hi Greg, Sasha, Please cherry pick upstream commit b17ef04bf3a4 ("drm/amd/display: Pass pwrseq inst for backlight and ABM") to stable kernel 6.6.x and newer. This fixes broken backlight adjustment on some AMD platforms with eDP panels. Thanks, Alex

[PATCH v2] pps: Remove embedded cdev to fix a use-after-free

Kernel panic - not syncing: Oops - BUG: Fatal exception This happens because pps_device_destruct() frees the pps_device with the embedded cdev immediately after calling cdev_del(), but, as the comment above cdev_del() notes, fops for previously opened cdevs are still callable even after cdev_del() returns. I think this bug has always been there: I can't explain why it suddenly started happening every time I reboot this particular board. In commit d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source."), George Spelvin suggested removing the embedded cdev. That seems like the simplest way to fix this, so I've implemented his suggestion, with pps_idr becoming the source of truth for which minor corresponds to which device. But now that pps_idr defines userspace visibility instead of cdev_add(), we need to be sure the pps->dev kobject refcount can't reach zero while userspace can still find it again. So, the idr_remove() call moves to pps_unregister_cdev(), and pps_idr now holds a reference to the pps->dev kobject. pps_core: source serial1 got cdev (251:1) <...> pps pps1: removed pps_core: unregistering pps1 pps_core: deallocating pps1 Fixes: d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source.")

5.10.225 stable kernel cgroup_mutex not held assertion failure

by Greg Thelen

Linux stable v5.10.226 suffers a lockdep warning when accessing /proc/PID/cpuset. cset_cgroup_from_root() is called without cgroup_mutex is held, which causes assertion failure. Bisect blames 5.10.225 commit 688325078a8b ("cgroup/cpuset: Prevent UAF in proc_cpuset_show()"). I've have not easily reproduced the problem that this change fixes, so I'm not sure if it's best to revert the fix or adapt it to meet the 5.10 locking expectations.

[PATCH 00/18] leds: switch to device_for_each_child_node_scoped()

by Javier Carrasco

This series switches from the device_for_each_child_node() macro to its scoped variant, which in general makes the code more robust if new early exits are added to the loops, because there is no need for explicit calls to fwnode_handle_put(). Depending on the complexity of the loop and its error handling, the code gets simplified and it gets easier to follow. The non-scoped variant of the macro is error-prone, and it has been the source of multiple bugs where the child node refcount was not decremented accordingly in error paths within the loops. The first patch of this series is a good example, which fixes that kind of bug that is regularly found in node iterators. The uses of device_for_each_child_node() with no early exits have been left untouched because their simpilicty justifies the non-scoped variant. Note that the child node is now declared in the macro, and therefore the explicit declaration is no longer required. The general functionality should not be affected by this modification. If functional changes are found, please report them back as errors.

[PATCH v4] memfd: `MFD_NOEXEC_SEAL` should not imply `MFD_ALLOW_SEALING`

by Barnabás Pőcze

`MFD_NOEXEC_SEAL` should remove the executable bits and set `F_SEAL_EXEC` to prevent further modifications to the executable bits as per the comment in the uapi header file: not executable and sealed to prevent changing to executable However, commit 105ff5339f498a ("mm/memfd: add MFD_NOEXEC_SEAL and MFD_EXEC") that introduced this feature made it so that `MFD_NOEXEC_SEAL` unsets `F_SEAL_SEAL`, essentially acting as a superset of `MFD_ALLOW_SEALING`. Nothing implies that it should be so, and indeed up until the second version of the of the patchset[0] that introduced `MFD_EXEC` and `MFD_NOEXEC_SEAL`, `F_SEAL_SEAL` was not removed, however, it was changed in the third revision of the patchset[1] without a clear explanation. This behaviour is surprising for application developers, there is no documentation that would reveal that `MFD_NOEXEC_SEAL` has the additional effect of `MFD_ALLOW_SEALING`. Additionally, combined with `vm.memfd_noexec=2` it has the effect of making all memfds initially sealable. So do not remove `F_SEAL_SEAL` when `MFD_NOEXEC_SEAL` is requested, thereby returning to the pre-Linux 6.3 behaviour of only allowing sealing when `MFD_ALLOW_SEALING` is specified. Now, this is technically a uapi break. However, the damage is expected to be minimal. To trigger user visible change, a program has to do the following steps: - create memfd: - with `MFD_NOEXEC_SEAL`, - without `MFD_ALLOW_SEALING`; - try to add seals / check the seals. But that seems unlikely to happen intentionally since this change essentially reverts the kernel's behaviour to that of Linux <6.3, so if a program worked correctly on those older kernels, it will likely work correctly after this change. I have used Debian Code Search and GitHub to try to find potential breakages, and I could only find a single one. dbus-broker's memfd_create() wrapper is aware of this implicit `MFD_ALLOW_SEALING` behaviour, and tries to work around it[2]. This workaround will break. Luckily, this only affects the test suite, it does not affect the normal operations of dbus-broker. There is a PR with a fix[3]. I also carried out a smoke test by building a kernel with this change and booting an Arch Linux system into GNOME and Plasma sessions. There was also a previous attempt to address this peculiarity by introducing a new flag[4].

This is sent because I believe it is worth at least a try; it can be easily reverted if bigger application breakages are discovered than initially imagined. --- mm/memfd.c | 9 ++++----- tools/testing/selftests/memfd/memfd_test.c | 2 +- 2 files changed, 5 insertions(+), 6 deletions(-) diff --git a/mm/memfd.c b/mm/memfd.c index 7d8d3ab3fa37..8b7f6afee21d 100644 --- a/mm/memfd.c +++ b/mm/memfd.c @@ -356,12 +356,11 @@ SYSCALL_DEFINE2(memfd_create, inode->i_mode &= ~0111; file_seals = memfd_file_seals_ptr(file); - if (file_seals) { - *file_seals &= ~F_SEAL_SEAL; + if (file_seals) *file_seals |= F_SEAL_EXEC; - } - } else if (flags & MFD_ALLOW_SEALING) { - /* MFD_EXEC and MFD_ALLOW_SEALING are set */ + } + + if (flags & MFD_ALLOW_SEALING) { file_seals = memfd_file_seals_ptr(file); if (file_seals) *file_seals &= ~F_SEAL_SEAL; diff --git a/tools/testing/selftests/memfd/memfd_test.c b/tools/testing/selftests/memfd/memfd_test.c index 95af2d78fd31..7b78329f65b6 100644 --- a/tools/testing/selftests/memfd/memfd_test.c +++ b/tools/testing/selftests/memfd/memfd_test.c @@ -1151,7 +1151,7 @@ static void test_noexec_seal(void) mfd_def_size, MFD_CLOEXEC | MFD_NOEXEC_SEAL); mfd_assert_mode(fd, 0666); - mfd_assert_has_seals(fd, F_SEAL_EXEC); + mfd_assert_has_seals(fd, F_SEAL_SEAL | F_SEAL_EXEC); mfd_fail_chmod(fd, 0777); close(fd); } -- 2.45.2

Re: Bluetooth kernel BUG with Intel AX211 (regression in 6.1.83)

by Linux regression tracking (Thorsten Leemhuis)

Hi stable team (and Bluetooth maintainers), I noticed a regression report about a BT problem in 6.1.y: On 21.04.24 15:54, Jeremy Lainé wrote: > > After upgrading my kernel to Debian's latest version (6.1.85), I > started encountering systematic kernel BUGs at boot, making the > bluetooth stack unusable.
