[PATCH v2 RESEND] EDAC/ti: Fix possible null pointer dereference in _emif_get_id()

by Ma Ke

In _emif_get_id(), of_get_address() may return NULL which is later dereferenced. Fix this bug by adding NULL check.

[PATCH] Bluetooth: hci_core: fix suspicious RCU usage in hci_conn_drop()

by Yunseong Kim

Protection from the queuing operation is achieved with an RCU read lock to avoid calling 'queue_delayed_work()' after 'cancel_delayed_work()', but this does not apply to 'hci_conn_drop()'. commit deee93d13d38 ("Bluetooth: use hdev->workqueue when queuing hdev->{cmd,ncmd}_timer works") The situation described raises concerns about suspicious RCU usage in a corrupted context. CPU 1 CPU 2 hci_dev_do_reset() synchronize_rcu() hci_conn_drop() drain_workqueue() <-- no RCU read protection during queuing. --> queue_delayed_work() It displays a warning message like the following Bluetooth: hci0: unexpected cc 0x0c38 length: 249 > 2 ============================= WARNING: suspicious RCU usage 6.10.0-rc6-01340-gf14c0bb78769 #5 Not tainted ----------------------------- net/mac80211/util.c:4000 RCU-list traversed in non-reader section!! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 2 locks held by syz-executor/798: #0: ffff800089a3de50 (rtnl_mutex){+.+.}-{4:4}, at: rtnl_lock+0x28/0x40 net/core/rtnetlink.c:79 stack backtrace: CPU: 0 PID: 798 Comm: syz-executor Not tainted 6.10.0-rc6-01340-gf14c0bb78769 #5 Hardware name: linux,dummy-virt (DT) Call trace: dump_backtrace.part.0+0x1b8/0x1d0 arch/arm64/kernel/stacktrace.c:317 dump_backtrace arch/arm64/kernel/stacktrace.c:323 [inline] show_stack+0x34/0x50 arch/arm64/kernel/stacktrace.c:324 __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0xf0/0x170 lib/dump_stack.c:114 dump_stack+0x20/0x30 lib/dump_stack.c:123 lockdep_rcu_suspicious+0x204/0x2f8 kernel/locking/lockdep.c:6712 ieee80211_check_combinations+0x71c/0x828 [mac80211] ieee80211_check_concurrent_iface+0x494/0x700 [mac80211] ieee80211_open+0x140/0x238 [mac80211] __dev_open+0x270/0x498 net/core/dev.c:1474 __dev_change_flags+0x47c/0x610 net/core/dev.c:8837 dev_change_flags+0x98/0x170 net/core/dev.c:8909 devinet_ioctl+0xdf0/0x18d0 net/ipv4/devinet.c:1177 inet_ioctl+0x34c/0x388 net/ipv4/af_inet.c:1003 sock_do_ioctl+0xe4/0x240 net/socket.c:1222 sock_ioctl+0x4cc/0x740 net/socket.c:1341 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:907 [inline] __se_sys_ioctl fs/ioctl.c:893 [inline] __arm64_sys_ioctl+0x184/0x218 fs/ioctl.c:893 __invoke_syscall arch/arm64/kernel/syscall.c:34 [inline] invoke_syscall+0x90/0x2e8 arch/arm64/kernel/syscall.c:48 el0_svc_common.constprop.0+0x200/0x2a8 arch/arm64/kernel/syscall.c:131 el0_svc+0x48/0xc0 arch/arm64/kernel/entry-common.c:712 el0t_64_sync_handler+0x120/0x130 arch/arm64/kernel/entry-common.c:730 el0t_64_sync+0x190/0x198 arch/arm64/kernel/entry.S:598 This patch attempts to fix that issue with the same convention.

[RESEND PATCH] rtc: ds1343: Force SPI chip select to be active high

by Ian Abbott

Commit 3b52093dc917 ("rtc: ds1343: Do not hardcode SPI mode flags") bit-flips (^=) the existing SPI_CS_HIGH setting in the SPI mode during device probe. This will set it to the wrong value if the spi-cs-high property has been set in the devicetree node. Just force it to be set active high and get rid of some commentary that attempted to explain why flipping the bit was the correct choice.

[PATCH fro 6.11 0/2] ASoC SOF: ipc4-topology: Fix LinkID handling for ChainDMA

by Peter Ujfalusi

Hi, A recent patch available in 6.10 [1] uncovered two issues on how the DMA Link ID is tracked with ChainDMA and can cause under specific conditions [2] to cause a DSP panic. The issue is not academic as we have one user report of it: https://github.com/thesofproject/linux/issues/5116 The patches have been marked for stable backport to made there way to 6.10. The first patch is fixing a code move patch, for older than 6.9 we would need different patch to fix the original code, but since the issue is only valid for 6.10, I will do that at a later time. Mark, can you please schedule these as fixes for 6.11 to get them fast to 6.10? Thank you.
