2023-12-06ring-buffer: Test last update in 32bit version of __rb_time_read()Steven Rostedt (Google)
Since 64 bit cmpxchg() is very expensive on 32bit architectures, the timestamp used by the ring buffer does some interesting tricks to be able to still have an atomic 64 bit number. It originally just used 60 bits and broke it up into two 32 bit words where the extra 2 bits were used for synchronization. But this was not enough for all use cases, and all 64 bits were required. The 32bit version of the ring buffer timestamp was then broken up into 3 32bit words using the same counter trick. But one update was not done. The check to see if the read operation was done without interruption only checked the first two words and not last one (like it had before this update). Fix it by making sure all three updates happen without interruption by comparing the initial counter with the last updated counter.

2023-12-06ring-buffer: Force absolute timestamp on discard of eventSteven Rostedt (Google)
There's a race where if an event is discarded from the ring buffer and an interrupt were to happen at that time and insert an event, the time stamp is still used from the discarded event as an offset. This can screw up the timings. If the event is going to be discarded, set the "before_stamp" to zero. When a new event comes in, it compares the "before_stamp" with the "write_stamp" and if they are not equal, it will insert an absolute timestamp. This will prevent the timings from getting out of sync due to the discarded event.

2023-12-06cifs: reconnect worker should take reference on server struct unconditionallyShyam Prasad N
Reconnect worker currently assumes that the server struct is alive and only takes reference on the server if it needs to call smb2_reconnect. With the new ability to disable channels based on whether the server has multichannel disabled, this becomes a problem when we need to disable established channels. While disabling the channels and deallocating the server, there could be reconnect work that could not be cancelled (because it started). This change forces the reconnect worker to unconditionally take a reference on the server when it runs. Also, this change now allows smb2_reconnect to know if it was called by the reconnect worker. Based on this, the cifs_put_tcp_session can decide whether it can cancel the reconnect work synchronously or not.

2023-12-06Revert "cifs: reconnect work should have reference on server struct"Shyam Prasad N
This reverts commit 19a4b9d6c372cab6a3b2c9a061a236136fe95274. This earlier commit was making an assumption that each mod_delayed_work called for the reconnect work would result in smb2_reconnect_server being called twice. This assumption turns out to be untrue. So reverting this change for now. I will submit a follow-up patch to fix the actual problem in a different way.

A concurrently running sock_orphan() may NULL the sk_socket pointer in between check and deref. Follow other users (like nft_meta.c for instance) and acquire sk_callback_lock before dereferencing sk_socket.

2023-12-06Merge tag 'ffa-fixes-6.7' of ↵Arnd Bergmann
git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm FF-A fixes for v6.7 A bunch of fixes addressing issues around the notification support that was added this cycle. They address issue in partition IDs handling in ffa_notification_info_get(), notifications cleanup path and the size of the allocation in ffa_partitions_cleanup(). It also adds check for the notification enabled state so that the drivers registering the callbacks can be rejected if not enabled/supported. It also moves the partitions setup operation after the notification initialisation so that the driver has the correct state for notification enabled/supported before the partitions are initialised/setup. It also now allows FF-A initialisation to complete successfully even when the notification initialisation fails as it is an optional support in the specification. Initial support just allowed it only if the firmware didn't support notifications. Finally, it also adds a fix for smatch warning by declaring ffa_bus_type structure in the header. * tag 'ffa-fixes-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Fix ffa_notification_info_get() IDs handling firmware: arm_ffa: Fix the size of the allocation in ffa_partitions_cleanup() firmware: arm_ffa: Fix FFA notifications cleanup path firmware: arm_ffa: Add checks for the notification enabled state firmware: arm_ffa: Setup the partitions after the notification initialisation firmware: arm_ffa: Allow FF-A initialisation even when notification fails firmware: arm_ffa: Declare ffa_bus_type structure in the header Link: https://lore.kernel.org/r/20231116191603.929767-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
