From: Sascha Hlusiak <contact@saschahlusiak.de> Date: Tue, 29 Sep 2009 23:27:05 +0200 > When requesting all prl entries (kprl.addr == INADDR_ANY) and there are > more prl entries than there is space passed from userspace, the existing > code would always copy cmax+1 entries, which is more than can be handled. > > This patch makes the kernel copy only exactly cmax entries. > > Signed-off-by: Sascha Hlusiak <contact@saschahlusiak.de> > Acked-By: Fred L. Templin <Fred.L.Templin@boeing.com> Applied and queued up for -stable, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
