From b20428663afa1a6351eb943b5f2992a744c18797 Mon Sep 17 00:00:00 2001

Subject: [PATCH] shm: Close file descriptors not needed
Commit 5a981ee8 implemented a fallback path for platforms which do not
support mremap() such as FreeBSD.
To do so, the file descriptor for the mmap() is not closed immediately
but instead kept as long as the pool exists.
That induces more file descriptors kept open for longer, which in turn
may cause problems as wl_shm may be using a lot of file descriptors,
especially with Xwayland which can create a lot of pixmaps on behalf of
its X11 clients.
For platforms where mremap() is available, keeping those file
descriptors opened is a bit of a waste and may cause exhaustion of file
descriptors sooner that before commit 5a981ee8.
Only keep the mmap() file descriptor open on platforms which do not
implement mremap() and close it immediately as before on others.

Tue Jan 11 08:29:19 UTC 2022 - Alynx Zhou <alynx.zhou@suse.com>
- Add wayland-shm-Close-file-descriptors-not-needed.patch: For
platforms that support mremap(), we don't need to hold file
descriptors all the time, because programs like Xwayland will
hold a lot of file descriptors and may crash, this patch close
file descriptors earlier for those platforms (bsc#1194190).

- Update to release 1.20
* A few protocol additions: wl_surface.offset allows clients to
update a surface's buffer offset independently from the
buffer, wl_output.name and description allow clients to
identify outputs without depending on xdg-output-unstable-v1.
* In protocol definitions, events have a new "type" attribute
and can now be marked as destructors.
* A number of bug fixes, including a race condition when
destroying proxies in multi-threaded clients.
