[PATCH 5.15.y] cifs: fix mid leak during reconnection after timeout threshold

by Harshit Mogalapalli

From: Shyam Prasad N <nspmangalore(a)gmail.com> commit 69cba9d3c1284e0838ae408830a02c4a063104bc upstream. When the number of responses with status of STATUS_IO_TIMEOUT exceeds a specified threshold (NUM_STATUS_IO_TIMEOUT), we reconnect the connection. But we do not return the mid, or the credits returned for the mid, or reduce the number of in-flight requests. This bug could result in the server->in_flight count to go bad, and also cause a leak in the mids. This change moves the check to a few lines below where the response is decrypted, even of the response is read from the transform header. This way, the code for returning the mids can be reused. Also, the cifs_reconnect was reconnecting just the transport connection before. In case of multi-channel, this may not be what we want to do after several timeouts. Changed that to reconnect the session and the tree too. Also renamed NUM_STATUS_IO_TIMEOUT to a more appropriate name MAX_STATUS_IO_TIMEOUT.

If it was, we delete the folio we just added to the swap cache and exit. However, __read_swap_cache_async() returns the folio locked when it is newly allocated, which is always true for this path, and the folio is ref'd. Make sure to unlock and put the folio before returning. This was discovered by code inspection, probably because this path handles a race condition that should not happen often, and the bug would not crash the system, it will only strand the folio indefinitely.

[PATCH v4 2/2] fs/aio: Make io_cancel() generate completions again

by Bart Van Assche

The following patch accidentally removed the code for delivering completions for cancelled reads and writes to user space: "[PATCH 04/33] aio: remove retry-based AIO" (https://lore.kernel.org/all/1363883754-27966-5-git-send-email-koverstreet@g…) From that patch: - if (kiocbIsCancelled(iocb)) { - ret = -EINTR; - aio_complete(iocb, ret, 0); - /* must not access the iocb after this */ - goto out; - } This leads to a leak in user space of a struct iocb. Hence this patch that restores the code that reports to user space that a read or write has been cancelled successfully.

[PATCH v2] nvmem: rmem: Fix return value of rmem_read()

by Joy Chakraborty

reg_read() callback registered with nvmem core expects an integer error as a return value but rmem_read() returns the number of bytes read, as a result error checks in nvmem core fail even when they shouldn't. Return 0 on success where number of bytes read match the number of bytes requested and a negative error -EINVAL on all other cases.

[PATCH net 00/10] mptcp: more misc. fixes for v6.8

by Matthieu Baerts (NGI0)

This series includes 6 types of fixes: - Patch 1 fixes v4 mapped in v6 addresses support for the userspace PM, when asking to delete a subflow. It was done everywhere else, but not there. Patch 2 validates the modification, thanks to a subtest in mptcp_join.sh. These patches can be backported up to v5.19. - Patch 3 is a small fix for a recent bug-fix patch, just to avoid printing an irrelevant warning (pr_warn()) once. It can be backported up to v5.6, alongside the bug-fix that has been introduced in the v6.8-rc5. - Patches 4 to 6 are fixes for bugs found by Paolo while working on TCP_NOTSENT_LOWAT support for MPTCP. These fixes can improve the performances in some cases. Patches can be backported up to v5.6, v5.11 and v6.7 respectively. - Patch 7 makes sure 'ss -M' is available when starting MPTCP Join selftest as it is required for some subtests since v5.18. - Patch 8 fixes a possible double-free on socket dismantle. The issue always existed, but was unnoticed because it was not causing any problem so far. This fix can be backported up to v5.6. - Patch 9 is a fix for a very recent patch causing lockdep warnings in subflow diag. The patch causing the regression -- which fixes another issue present since v5.7 -- should be part of the future v6.8-rc6. Patch 10 validates the modification, thanks to a new subtest in diag.sh.
