Description Lev Makhlis 2005-05-04 18:19:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3

Description of problem:
Unlike its siblings shmctl32 and msgctl32, semctl32 in arch/x84_64/ia32/ipc32.c does not properly convert between 32-bit and 64-bit semid_ds.  As a result, semctl(2) calls from a 32-bit application don't work properly.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Copy /usr/bin/ipcs from an IA32 system.
2. Create some semaphores.
3. Run ipcs -s.

Actual Results:  ------ Semaphore Arrays --------
key        semid      owner      perms      nsems
0x00003039 0          lmakhlis  666        1
0x00003039 32769      lmakhlis  666        1
0x00003039 65538      lmakhlis  666        1
0x00003039 98307      lmakhlis  666        1
0x00003039 131076     lmakhlis  666        1
0x00003039 163845     lmakhlis  666        1

Expected Results:  Same as with native ipcs:

------ Semaphore Arrays --------
key        semid      owner      perms      nsems
0x00003039 0          lmakhlis  666        1
0x810940ac 32769      lmakhlis  666        2
