Biederman <ebiederm(a)xmission.com> commit 6ac1dc736b323011a55ecd1fc5897c24c4f77cbd upstream. Setting si_code to 0 is the same a setting si_code to SI_USER which is definitely not correct. With si_code set to SI_USER si_pid and si_uid will be copied to userspace instead of si_addr. Which is very wrong. So fix this by using a sensible si_code (SEGV_MAPERR) for this failure.

Patch "ftrace: Remove incorrect setting of glob search field" has been added to the 4.9-stable tree

Al Viro reported this: After that call of filter_parse_regex() we could have func_g.search not equal to glob only if glob started with '!' or '*'. In the former case we would've buggered off with -EINVAL (not = 1). In the latter we would've set func_g.search equal to glob + 1, calculated the length of that thing in func_g.len and proceeded to reset func_g.search back to glob. Suppose the glob is e.g. *foo*. We end up with func_g.type = MATCH_MIDDLE_ONLY; func_g.len = 3; func_g.search = "*foo"; Feeding that to ftrace_match_record() will not do anything sane - we will be looking for names containing "*foo" (->len is ignored for that one).

We store a SW state of the t11_t12 timing in 100usec units but have to program it in 100msec as required by HW. The rounding used during programming means there will be a mismatch between the SW and HW states of this value triggering a "PPS state mismatch" error. Avoid this by storing the already rounded-up value in the SW state. Note that we still calculate panel_power_cycle_delay with the finer 100usec granularity to avoid any needless waits using that version of the delay.

As a writable mount, it is not expected for overlayfs to return EINVAL/EROFS for fsync, even if dir/file is not changed. This commit fixes the case of fsync of directory, which is easier to address, because overlayfs already implements fsync file operation for directories. The problem reported by Raphael is that new PostgreSQL 10.0 with a database in overlayfs where lower layer in squashfs fails to start. The failure is due to fsync error, when PostgreSQL does fsync on all existing db directories on startup and a specific directory exists lower layer with no changes.

[Linux-stable-mirror] [PATCH 4.4.y] nvme: Fix managing degraded controllers

by Keith Busch

commit 3e1e21c7bfcf upstream Upstream is a near rewrite of the async nvme probe that ultimately didn't even cleanly merge in 4.5. This patch is a much smaller change targeted to the regression introduced in 4.4. If a controller is in a degraded mode that needs admin assistence to recover, we need to leave the controller running. We just want to disable namespace access without shuting the controller down.

Biederman <ebiederm(a)xmission.com> commit 6ac1dc736b323011a55ecd1fc5897c24c4f77cbd upstream. Setting si_code to 0 is the same a setting si_code to SI_USER which is definitely not correct. With si_code set to SI_USER si_pid and si_uid will be copied to userspace instead of si_addr. Which is very wrong. So fix this by using a sensible si_code (SEGV_MAPERR) for this failure.

Al Viro reported this: After that call of filter_parse_regex() we could have func_g.search not equal to glob only if glob started with '!' or '*'. In the former case we would've buggered off with -EINVAL (not = 1). In the latter we would've set func_g.search equal to glob + 1, calculated the length of that thing in func_g.len and proceeded to reset func_g.search back to glob. Suppose the glob is e.g. *foo*. We end up with func_g.type = MATCH_MIDDLE_ONLY; func_g.len = 3; func_g.search = "*foo"; Feeding that to ftrace_match_record() will not do anything sane - we will be looking for names containing "*foo" (->len is ignored for that one).
