2020-11-10drm/amd/display: Prevent freesync power optimization during validationIsabel Zhang
[Why] Due to the freesync power optimization increasing vtotal, the driver believes that MPO is supported. MPO is turned on. Freesync then exits, MPO can no longer be supported and immediate flip fails. This causes corruption on the panel. [How] Avoid the freesync optimization when doing validation so in the case freesync exits, driver can still support the configuration.

Obviously, this will cause an out-of-bounds read, because we can > access a smaller vc_font.data with a larger vc_font.height. Further there was only one user ever. - Android's loadfont, busybox and console-tools only ever use OP_GET and OP_SET - fbset documentation only mentions the kernel cmdline font: option, not anything else. - systemd used OP_COPY before release 232 published in Nov 2016 Now unfortunately the crucial report seems to have gone down with gmane, and the commit message doesn't say much. But the pull request hints at OP_COPY being broken https://github.com/systemd/systemd/pull/3651 So in other words, this never worked, and the only project which foolishly every tried to use it, realized that rather quickly too. Instead of trying to fix security issues here on dead code by adding missing checks, fix the entire thing by removing the functionality. Note that systemd code using the OP_COPY function ignored the return value, so it doesn't matter what we're doing here really - just in case a lone server somewhere happens to be extremely unlucky and running an affected old version of systemd. The relevant code from font_copy_to_all_vcs() in systemd was: /* copy font from active VT, where the font was uploaded to */ cfo.op = KD_FONT_OP_COPY; cfo.height = vcs.v_active-1; /* tty1 == index 0 */ (void) ioctl(vcfd, KDFONTOP, &cfo); Note this just disables the ioctl, garbage collecting the now unused callbacks is left for -next. v2: Tetsuo found the old mail, which allowed me to find it on another archive.

Merge procfs splice read fixes from Christoph Hellwig: "Greg reported a problem due to the fact that Android tests use procfs files to test splice, which stopped working with the changes for set_fs() removal. This series adds read_iter support for seq_file, and uses those for various proc files using seq_file to restore splice read support" [ Side note: Christoph initially had a scripted "move everything over" patch, which looks fine, but I personally would prefer us to actively discourage splice() on random files. So this does just the minimal basic core set of proc file op conversions. For completeness, and in case people care, that script was sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g' but I'll wait and see if somebody has a strong argument for using splice on random small /proc files before I'd run it on the whole kernel. - Linus ] * emailed patches from Christoph Hellwig <hch@lst.de>: proc "seq files": switch to ->read_iter proc "single files": switch to ->read_iter proc/stat: switch to ->read_iter proc/cpuinfo: switch to ->read_iter proc: wire up generic_file_splice_read for iter ops seq_file: add seq_read_iter

2020-11-07futex: Handle transient "ownerless" rtmutex state correctlyMike Galbraith
Gratian managed to trigger the BUG_ON(!newowner) in fixup_pi_state_owner(). This is one possible chain of events leading to this: Task Prio Operation T1 120 lock(F) T2 120 lock(F) -> blocks (top waiter) T3 50 (RT) lock(F) -> boosts T1 and blocks (new top waiter) XX timeout/ -> wakes T2 signal T1 50 unlock(F) -> wakes T3 (rtmutex->owner == NULL, waiter bit is set) T2 120 cleanup -> try_to_take_mutex() fails because T3 is the top waiter and the lower priority T2 cannot steal the lock. -> fixup_pi_state_owner() sees newowner == NULL -> BUG_ON() The comment states that this is invalid and rt_mutex_real_owner() must return a non NULL owner when the trylock failed, but in case of a queued and woken up waiter rt_mutex_real_owner() == NULL is a valid transient state. The higher priority waiter has simply not yet managed to take over the rtmutex. The BUG_ON() is therefore wrong and this is just another retry condition in fixup_pi_state_owner(). Drop the locks, so that T3 can make progress, and then try the fixup again. Gratian provided a great analysis, traces and a reproducer. The analysis is to the point, but it confused the hell out of that tglx dude who had to page in all the futex horrors again. Condensed version is above.

2020-11-07perf/core: Fix a memory leak in perf_event_parse_addr_filter()kiyin(尹亮)
As shown through runtime testing, the "filename" allocation is not always freed in perf_event_parse_addr_filter(). There are three possible ways that this could happen: - It could be allocated twice on subsequent iterations through the loop, - or leaked on the success path, - or on the failure path. Clean up the code flow to make it obvious that 'filename' is always freed in the reallocation path and in the two return paths as well. We rely on the fact that kfree(NULL) is NOP and filename is initialized with NULL. This fixes the leak. No other side effects expected. [ Dan Carpenter: cleaned up the code flow & added a changelog. ] [ Ingo Molnar: updated the changelog some more. ] Fixes: 375637bc5249 ("perf/core: Introduce address range filtering") Signed-off-by: "kiyin(尹亮)" <kiyin@tencent.com> Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: "Srivatsa S.

2020-11-07x86/platform/uv: Remove spaces from OEM IDsMike Travis
Testing shows that trailing spaces caused problems with the OEM_ID and the OEM_TABLE_ID. One being that the OEM_ID would not string compare correctly.
