[PATCH for-rc 0/2] Patches for 4.20 rc cycle

by Dennis Dalessandro

Hi Doug and Jason, Here are two patches that would be good to land in the RC. One fixes a bug found by KASAN that was marked stable. The other fixes something that was introduced in the last release cycle. Both patches are pretty small. --- Michael J.

[PATCH 2/2] libnvdimm, pfn: Pad pfn namespaces relative to other regions

by Dan Williams

Commit cfe30b872058 "libnvdimm, pmem: adjust for section collisions with 'System RAM'" enabled Linux to workaround occasions where platform firmware arranges for "System RAM" and "Persistent Memory" to collide within a single section boundary. Unfortunately, as reported in this issue [1], platform firmware can inflict the same collision between persistent memory regions. The approach of interrogating iomem_resource does not work in this case because platform firmware may merge multiple regions into a single iomem_resource range. Instead provide a method to interrogate regions that share the same parent bus. This is a stop-gap until the core-MM can grow support for hotplug on sub-section boundaries.

My suggestion, although I didn't looked too much on it: Apply it to v4.9 and higher only. I think I started fixing trace functionality on parisc around 4.6, which is probably why applying it fails on v4.4 and v3.x Helge

[PATCH v3] backlight: pwm_bl: Fix brightness levels for non-DT case.

by Enric Balletbo i Serra

Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED linearly to human eye")' allows the possibility to compute a default brightness table when there isn't the brightness-levels property in the DT. Unfortunately the changes made broke the pwm backlight for the non-DT boards. Usually, the non-DT boards don't pass the brightness levels via platform data, instead, it sets the max_brightness in their platform data and the driver calculates the level without a table. The offending patch assumed that when there is no brightness levels table we should create one, but this is clearly wrong for the non-DT case. After this patch the code handles the DT and the non-DT case taking in consideration also if max_brightness is set or not.

Security fixes for 4.14

by Ben Hutchings

I've backported a number of fixes for security issues affecting 4.14- stable. All of these are already fixed in 4.19-stable. Most of the issues involve filesystem validation, and I tested with the reproducers where available. For the BPF fix, I verified that the self-tests didn't regress and temporarily added logging to check that the mitigation is applied when needed.
