Description Michael Reifenberger 2001-08-14 10:20:01 UTC 
/compat/linux/usr/bin/ipcs [-s|-a] doesn't work

Fix: It is the needed step in getting "/compat/linux/usr/bin/ipcs -s" working.
Furthermore it enhances the sysv[sem|shm] sysctl's into tunables so they
can preset to usable values on modload.
How-To-Repeat: /compat/linux/usr/bin/ipcs [-s|-a]

There's no ipcs in the current default linux base... 

Is this still a problem on a recent FreeBSD? If yes, do you have 
updated patches?

Back to "open", maybe an upcomming SoC student is willing to have a look 
at this.

emulators/linux_dist-gentoo-stage3 comes with `ipcs` and `ipcrm`. running ipcs
[-s|-a] works without any problems.

`/usr/local/gentoo-stage3/usr/bin/ipcs -a`:

------ Shared Memory Segments --------
key        shmid      owner      perms      bytes      nattch     status

------ Semaphore Arrays --------
key        semid      owner      perms      nsems
0x74738b52 65536      arundel   600        1

------ Message Queues --------
key        msqid      owner      perms      used-bytes   messages

`/usr/local/gentoo-stage3/usr/bin/ipcs -s`:

------ Semaphore Arrays --------
key        semid      owner      perms      nsems
0x74738b52 65536      arundel   600        1

` /usr/local/gentoo-stage3/usr/bin/ipcrm -s 65536`

`/usr/local/gentoo-stage3/usr/bin/ipcs -s`:

------ Semaphore Arrays --------
key        semid      owner      perms      nsems

question is if `ipcs`/`ipcrm` is needed in emulators/linux_base-f*.

cheers.

the linux related changes in this PR have been committed in r83366.

the freebsd patches have also been committed. however it is unknown if this means linux ipc is fully functional now.

cheers.
