I just commited a patch (r217242) to head. Anyone who is using client side NFS on FreeBSD8.n should apply this patch. It is also available at: http://people.freebsd.org/~rmacklem/krpc.patch
It fixes a problem where the kernel rpc assumes that 4 bytes of data exists in the first mbuf without checking. If the data straddles multiple mbufs, it uses garbage and then a typical case will wedge for a minute or so until it times out and establishes a new TCP connection. It also replaces m_pullup() with m_copydata(), since m_pullup() can fail for rare cases when there is data available. (m_pullup() uses MGET(, M_DONTWAIT,) which can fail when mbuf allocation is constrainted, for example.) Thanks to john.gemignani at isilon.com for spotting this problem, rick _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
