[PATCH 6.7.y v2 0/5] Delay VERW - 6.7.y backport

by Pawan Gupta

v2: - Dropped already backported patch "x86/bugs: Add asm helpers for executing VERW". https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… - Boot tested with KASLR and KPTI enabled. - Rebased to v6.7.8 v1: https://lore.kernel.org/r/20240226-delay-verw-backport-6-7-y-v1-0-ab25f6431… This is the backport of recently upstreamed series that moves VERW execution to a later point in exit-to-user path. This is needed because in some cases it may be possible for data accessed after VERW executions may end into MDS affected CPU buffers. Moving VERW closer to ring transition reduces the attack surface. Patch 2/7: A conflict was resolved for the hunk swapgs_restore_regs_and_return_to_usermode.

[PATCH net 0/2] selftests: mptcp: fixes for diag.sh

by Matthieu Baerts (NGI0)

Here are two patches fixing issues in MPTCP diag.sh kselftest: - Patch 1 makes sure the exit code is '1' in case of error, and not the test ID, not to return an exit code that would be wrongly interpreted by the ksefltests framework, e.g. '4' means 'skip'. - Patch 2 avoids waiting for unnecessary conditions, which can cause timeouts in some very slow environments.

[PATCH stable 6.1] NFS: Fix data corruption caused by congestion.

by NeilBrown

when AOP_WRITEPAGE_ACTIVATE is returned (as NFS does when it detects congestion) it is important that the page is redirtied. nfs_writepage_locked() doesn't do this, so files can become corrupted as writes can be lost. Note that this is not needed in v6.8 as AOP_WRITEPAGE_ACTIVATE cannot be returned. It is needed for kernels v5.18..v6.7. From 6.3 onward the patch is different as it needs to mention "folio", not "page".

[REGRESSION][PATCH 5.15 v1] Revert "drm/bridge: lt8912b: Register and attach our DSI device at probe"

by max.oss.09＠gmail.com

From: Max Krummenacher <max.krummenacher(a)toradex.com> This reverts commit ef4a40953c8076626875ff91c41e210fcee7a6fd. The commit was applied to make further commits apply cleanly, but the commit depends on other commits in the same patchset. I.e. the controlling DSI host would need a change too. Thus one would need to backport the full patchset changing the DSI hosts and all downstream DSI device drivers. Revert the commit and fix up the conflicts with the backported fixes to the lt8912b driver.

EFI/x86 backports for v6.1

by Ard Biesheuvel

Please consider the patches below for backporting to v6.1. They should all apply cleanly in the given order. These are prerequisites for NX compat support on x86, but the remaining changes do not apply cleanly and will be sent as a patch series at a later date. By themselves, these changes not only constitute a reasonable cleanup, they are also needed for future support of x86s [0] CPUs that are no longer able to transition out of long mode.
