CVS commit: [netbsd-3] src/sys
Module Name: src
Committed By: snj
Date: Sat Apr 11 06:18:21 UTC 2009
src/sys/kern [netbsd-3]: uipc_usrreq.c
src/sys/sys [netbsd-3]: file.h
Apply patch (requested by mlelstv in ticket #2004):
Avoid deep recursion and file descriptor exhaustion.
1. unp_detach: go not call unp_gc directly for descriptors
that are unixdomain sockets themselves. Instead mark them
for cleanup during garbage collection.
2. unp_gc: handle detach of descriptors that were marked earlier.
3. prohibit transfer of descriptors within SCM_RIGHTS messages if
(num_files_in_transit > maxfiles / unp_rights_ratio)
