[PATCH v2 4/5] drm/vc4: fix fb references in async update

by Helen Koike

Async update callbacks are expected to set the old_fb in the new_state so prepare/cleanup framebuffers are balanced. Calling drm_atomic_set_fb_for_plane() (which gets a reference of the new fb and put the old fb) is not required, as it's taken care by drm_mode_cursor_universal() when calling drm_atomic_helper_update_plane().

In other platforms (VC4, AMD, Rockchip), there is a hidden drm_framebuffer_get(new_fb)/drm_framebuffer_put(old_fb) in async_update that is wrong, but I couldn't identify those here, not sure if it is hidden somewhere else, but if tests fail this is probably the cause.

[PATCH 06/30] perf probe: Fix getting the kernel map

by Arnaldo Carvalho de Melo

From: Adrian Hunter <adrian.hunter(a)intel.com> Since commit 4d99e4136580 ("perf machine: Workaround missing maps for x86 PTI entry trampolines"), perf tools has been creating more than one kernel map, however 'perf probe' assumed there could be only one. Fix by using machine__kernel_map() to get the main kernel map.

+ fs-allow-opening-only-regular-files-during-execve.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: fs/open.c: allow opening only regular files during execve() has been added to the -mm tree. Its filename is fs-allow-opening-only-regular-files-during-execve.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/fs-allow-opening-only-regular-file… and later at http://ozlabs.org/~akpm/mmotm/broken-out/fs-allow-opening-only-regular-file… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Tetsuo Handa <penguin-kernel(a)I-love.SAKURA.ne.jp> Subject: fs/open.c: allow opening only regular files during execve() syzbot is hitting lockdep warning [1] due to trying to open a fifo during an execve() operation. But we don't need to open non regular files during an execve() operation, for all files which we will need are the executable file itself and the interpreter programs like /bin/sh and ld-linux.so.2 . Since the manpage for execve(2) says that execve() returns EACCES when the file or a script interpreter is not a regular file, and the manpage for uselib(2) says that uselib() can return EACCES, and we use FMODE_EXEC when opening for execve()/uselib(), we can bail out if a non regular file is requested with FMODE_EXEC set. Since this deadlock followed by khungtaskd warnings is trivially reproducible by a local unprivileged user, and syzbot's frequent crash due to this deadlock defers finding other bugs, let's workaround this deadlock until we get a chance to find a better solution.
