Rewrite of the following commit but adjusted pre-64-bit time_t
|
||||
conversion. We want to follow the same upstream behaviour and return
|
||||
EINVAL for unknown commands rather than to attempt the command with an
|
||||
argument of {0} which has likely never been tested upstream.

sysvipc: Return EINVAL for invalid semctl commands
|
||||
|
||||
It avoids regressions on possible future commands that might require
|
||||
additional libc support. The downside is new commands added by newer
|
||||
kernels will need further glibc support.
|
||||
|
||||
Checked on x86_64-linux-gnu and i686-linux-gnu (Linux v4.15 and v5.4).
