[PATCH 1/1] xhci: Fresco FL1100 controller should not have BROKEN_MSI quirk set.

by Mathias Nyman

The Fresco Logic FL1100 controller needs the TRUST_TX_LENGTH quirk like other Fresco controllers, but should not have the BROKEN_MSI quirks set. BROKEN_MSI quirk causes issues in detecting usb drives connected to docks with this FL1100 controller. The BROKEN_MSI flag was apparently accidentally set together with the TRUST_TX_LENGTH quirk Original patch went to stable so this should go there as well.

[PATCH] mm/damon/dbgfs: Protect targets destructions with kdamond_lock

by SeongJae Park

DAMON debugfs interface iterates current monitoring targets in 'dbgfs_target_ids_read()' while holding the corresponding 'kdamond_lock'. However, it also destructs the monitoring targets in 'dbgfs_before_terminate()' without holding the lock. This can result in a use_after_free bug. This commit avoids the race by protecting the destruction with the corresponding 'kdamond_lock'. Reported-by: Sangwoo Bae <sangwoob(a)amazon.com> Fixes: 4bc05954d007 ("mm/damon: implement a debugfs-based user space interface") Signed-off-by: SeongJae Park <sj(a)kernel.org> Cc: <stable(a)vger.kernel.org> # 5.15.x --- This cannot cleanly applied on 5.15.y tree.

patch "usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear." added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear. to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From b1e0887379422975f237d43d8839b751a6bcf154 Mon Sep 17 00:00:00 2001 From: Vincent Pelletier <plr.vincent(a)gmail.com> Date: Sat, 18 Dec 2021 02:18:40 +0000 Subject: usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear. ffs_data_clear is indirectly called from both ffs_fs_kill_sb and ffs_ep0_release, so it ends up being called twice when userland closes ep0 and then unmounts f_fs. If userland provided an eventfd along with function's USB descriptors, it ends up calling eventfd_ctx_put as many times, causing a refcount underflow. NULL-ify ffs_eventfd to prevent these extraneous eventfd_ctx_put calls. Also, set epfiles to NULL right after de-allocating it, for readability. For completeness, ffs_data_clear actually ends up being called thrice, the last call being before the whole ffs structure gets freed, so when this specific sequence happens there is a second underflow happening (but not being reported): /sys/kernel/debug/tracing# modprobe usb_f_fs /sys/kernel/debug/tracing# echo ffs_data_clear > set_ftrace_filter /sys/kernel/debug/tracing# echo function > current_tracer /sys/kernel/debug/tracing# echo 1 > tracing_on (setup gadget, run and kill function userland process, teardown gadget) /sys/kernel/debug/tracing# echo 0 > tracing_on /sys/kernel/debug/tracing# cat trace smartcard-openp-436 [000] ..... 1946.208786: ffs_data_clear <-ffs_data_closed smartcard-openp-431 [000] ..... 1946.279147: ffs_data_clear <-ffs_data_closed smartcard-openp-431 [000] .n... 1946.905512: ffs_data_clear <-ffs_data_put Warning output corresponding to above trace: [ 1946.284139] WARNING: CPU: 0 PID: 431 at lib/refcount.c:28 refcount_warn_saturate+0x110/0x15c [ 1946.293094] refcount_t: underflow; use-after-free.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱. Targeted tests -------------- Test runs for patches always include a set of base tests, plus some tests chosen based on the file paths modified by the patch. The latter are called "targeted tests". If no targeted tests are run, that means no patch-specific tests are available. Please, consider contributing a targeted test for related patches to increase test coverage. See https://docs.engineering.redhat.com/x/_wEZB for more details.

[PATCH net 1/1] igb: fix deadlock caused by taking RTNL in RPM resume path

by Tony Nguyen

From: Heiner Kallweit <hkallweit1(a)gmail.com> Recent net core changes caused an issue with few Intel drivers (reportedly igb), where taking RTNL in RPM resume path results in a deadlock. See [0] for a bug report. I don't think the core changes are wrong, but taking RTNL in RPM resume path isn't needed. The Intel drivers are the only ones doing this. See [1] for a discussion on the issue. Following patch changes the RPM resume path to not take RTNL.
