From 4c2a3dbe7b652e679c9228d7d8c81aa641bd968b Mon Sep 17 00:00:00 2001 From: duerpei Date: Mon, 14 Mar 2022 13:27:43 +0800 Subject: Fix potential memory leak of two pointers (xwayland and client) This backports four patches from weston to solve a memory leak problem These four patches are: https://gitlab.freedesktop.org/wayland/weston/-/commit/5a6604a7a2e52e5cd84c1f53724b3f7c325b5dff.patch https://gitlab.freedesktop.org/wayland/weston/-/commit/f53c05d3c2c19c139c52e9bd621c2654dd3dac69.patch https://gitlab.freedesktop.org/wayland/weston/-/commit/e2583ca0844bd7a8ce4fc94da9ad67edf49ffd45.patch https://gitlab.freedesktop.org/wayland/weston/-/commit/8740037a93c7c4400cc381ecf3009d1e4014be07.patch The following is the valgrind log: 160 bytes in 1 blocks are definitely lost in loss record 39 of 66 at 0x484B64C: calloc (in /usr/lib/valgrind/vgpreload_memcheck-arm64-linux.so) by 0x4A73C87: ??? (in /usr/lib/libweston-desktop-8.so.0.0.0) by 0x4A7184F: weston_desktop_create (in /usr/lib/libweston-desktop-8.so.0.0.0) by 0x487096B: ivi_desktop_init (in /usr/lib/agl-compositor/libexec_compositor.so.0.0.0) by 0x486F5E7: wet_main (in /usr/lib/agl-compositor/libexec_compositor.so.0.0.0) by 0x48B010F: (below main) (in /lib/libc-2.31.so) In agl-compositor/src/composiotr.c "ivi->desktop->compositor->xwayland" is zalloced by wet_main()->ivi_desktop_init()->weston_desktop_create()->weston_desktop_xwayland_init() "ivi->desktop->compositor->xwayland->client" is zalloced by wet_main()->ivi_desktop_init()->weston_desktop_create()->weston_desktop_xwayland_init()->weston_desktop_client_create() "ivi->desktop->compositor->xwayland" and "ivi->desktop->compositor->xwayland->client" The memory pointed to has not been released Now, I want to free the memory pointed by the two pointers. What can do this is the function of weston_desktop_xwayland_fini() in 0003-libweston-desktop-add-weston_desktop_xwayland_fini.patch And the submission of this patch depends on the first three patches, so I submitted these four patches.
