Subject: [PATCH] Fix handling of collating symbols in fnmatch (bug 26620)
The variable idx contains the index into the extra array, whereas wextra
points into the extra array at this index, containing the length of the
following collating sequence in the wide character representation.

From 574500a108be1d2a6a0dc97a075c9e0a98371aba Mon Sep 17 00:00:00 2001

Subject: [PATCH] sysvipc: Fix SEM_STAT_ANY kernel argument pass [BZ #26637]
Handle SEM_STAT_ANY the same way as SEM_STAT so that the buffer argument
of SEM_STAT_ANY is properly passed to the kernel and back.
The regression testcase checks for Linux specifix SysV ipc message
control extension. For IPC_INFO/SEM_INFO it tries to match the values
against the tunable /proc values and for SEM_STAT/SEM_STAT_ANY it
check if the create message queue is within the global list returned
by the kernel.
Checked on x86_64-linux-gnu and on i686-linux-gnu (Linux v5.4 and on
Linux v4.15).
