Description Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2007-01-06 14:10:41 UTC
Reported late last year and doesn't seem to have it's own bug yet:

Normally, when a process dies it becomes a zombie.
If the parent dies (before or after the child), the child
is adopted by init. Init will reap the child.

The program included below DOES NOT get reaped.

Do like so:

gcc -m32 -O2 -std=gnu99 -o foo foo.c
while true; do killall -9 foo; ./foo; sleep 1; done

Another one that took some digging. I'll post this info to CVE too.
proposed metadata:
[linux < 2.6.16.47]
[linux < 2.6.19.3]  
The commit IDs are (respectively): 
f95540a5193f909b5700555ceafc69bcb13d2174
b4e8b1a91dd54ad653036367a11ff8b7cf109534 
Note: I couldn't find the commit IDs at git.kernel.org.. but they exist in the corresponding changelogs:
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.16.47
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.19.3

[gp < 2.6.19-3]
Comment 2 unnamedrambler 2008-03-07 19:24:36 UTC
metadata correction:
[gp < 2.6.19-3] should be [gp < 2.6.19-7]
