Bug ID: 421868
Summary: Bad check for mmap return value
Product: frameworks-kwayland
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: client
Assignee: mgraess...@kde.org

Target Milestone: ---
Created attachment 128670
--> https://bugs.kde.org/attachment.cgi?id=128670&action=edit
proposed patch
In the file shm_pool.cpp there are 2 places where the return value of mmap() is
checked in a way that it expects a zero on failure. However this is wrong, mmap
returns MAP_FAILED (or -1) on error.
Patch attached.
