Bug ID: 106122
Summary: Weston segfaults on startup if wl_display_create fails
Product: Wayland
Version: unspecified
Hardware: All
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: weston
Assignee: [email protected]
Reporter: [email protected]
The call to wl_display_create does not check if the returned result is NULL,
which can happen (eg if epoll is not compiled into the kernel). This can cause
a segfault on startup.
See
https://github.com/wayland-project/weston/blob/42c0e14808bfd39e1a2eea34f43f0b5fe20fbb16/compositor/main.c#L1886,
and

for an example of where wl_display_create may return NULL.
