[patch 10/26] Fix error returns in sys_socketpair()
From: Greg Kroah-Hartman
Date: Mon Nov 19 2007 - 13:25:00 EST
2.6.22-stable review patch. If anyone has any objections, please let us
know.
------------------
From: David Miller <davem@xxxxxxxxxxxxx>
patch bf3c23d171e35e6e168074a1514b0acd59cfd81a in mainline.
[NET]: Fix error reporting in sys_socketpair().
If either of the two sock_alloc_fd() calls fail, we
forget to update 'err' and thus we'll erroneously
return zero in these cases.
Based upon a report and patch from Rich Paul, and
commentary from Chuck Ebbert.
