Please apply 02eec6c9fc0c ("MIPS: netlogic: xlr: Remove erroneous check in nlm_fmn_send()") to v4.4.y

by Guenter Roeck

Commit 02eec6c9fc0c ("MIPS: netlogic: xlr: Remove erroneous check in nlm_fmn_send()") fixes a build error in v4.4.y, seen when building mips:nlm_xlr_defconfig. In file included from ../arch/mips/netlogic/common/irq.c:65: ../arch/mips/include/asm/netlogic/xlr/fmn.h: In function 'nlm_fmn_send': ../arch/mips/include/asm/netlogic/xlr/fmn.h:304:22: error: bitwise comparison always evaluates to false The patch is only needed in v4.4.y; it has already been applied to more recent branches. Thanks, Guenter

Stable branches missing ed7a01fd3fd7

by Håkon Bugge

Hi Greg, Commit 00313983cda6 ("RDMA/nldev: provide detailed CM_ID information") is in the following stable releases: stable/linux-4.17.y stable/linux-4.18.y stable/linux-4.19.y stable/linux-4.20.y stable/linux-5.0.y stable/linux-5.1.y stable/linux-5.2.y stable/linux-5.3.y stable/master It has a potential for a big leak of task_struct's, and if the case is hit, the number of task_struct entries in /proc/slabinfo increases rapidly. The fix, ed7a01fd3fd7 ("RDMA/restrack: Release task struct which was hold by CM_ID object"), is in the following stable releases: stable/linux-4.20.y stable/linux-5.0.y stable/linux-5.1.y stable/linux-5.2.y stable/linux-5.3.y stable/master Hence, this commit needs to be included in 4-17..4.19. Thxs, Håkon

[PATCH 4/4] seccomp: test SECCOMP_RET_USER_NOTIF_ALLOW

by Christian Brauner

Test whether a syscall can be performed after having been intercepted by the seccomp notifier. The test uses dup() and kcmp() since it allows us to nicely test whether the dup() syscall actually succeeded by comparing whether the fd refers to the same underlying struct file.
