Add vfs.nfs.pos_cache_timeout to complement vfs.nfs.neg_cache_timeout.
Because NFSv3 is stateless, the client normally relies on the server
returning ESTALE (Stale NFS handle) to determine whether a relookup is
needed.  However, this does not cover namespace issues such as rename()s
and it is possible to get into a situation where a NFS client winds up
getting permanently out of sync with a server, requiring remounting to
fix.

The positive cache timeout will force open/stat and other namespace
operations to re-lookup the name, even if the file handle is still
valid.  The performance impact tested via a buildworld with a read-only
NFS mounted /usr/src appears to be minimal.

The positive cache timeout defaults to 3 second, same as the negative cache
timeout.  The timeout can be adjusted on the fly for any new namespace
lookups but changing the sysctl will not change any namespace lookups already
cached until they timeout.

13 years agoSome non-802.11e non-standard conforming APs use seperate TX sequences
Sepherosa Ziehau [Fri, 15 Jun 2007 12:04:45 +0000 (12:04 +0000)]
Some non-802.11e non-standard conforming APs use seperate TX sequences
for non-beacon frames and beacons.  If local cache of <addr2,seq,fragno>
tuple is updated when beacons from such kind of AP are received, 802.11
duplication detection mechanism may decide to discard non-beacon retry
frames if its sequence is less than or equal to just received beacon's.
Together with the poor TX rate control algorithm chosen by these kinds
of APs, i.e. a lot of retry data frames, a TCP connection can be choked
by STA's duplication detection mechanism.

To handle these kinds of APs (yep, we are in the world of compat):
Don't update cache of <addr2,seq,fragno> tuple for multicast or broadcast
802.11 MAC frames.  This does not violate IEEE Std 802.11, 1999 Edition
subclause 9.2.9, which actually allows us to "omit tuples obtained from
broadcast/multicast ...".

Thank Petr Janda <elekktretterr@exemail.com.au> for providing all
necessary 802.11 tcpdumps to track down the problem.

Thank dillon@ for analyzing some tcpdumps which leads me to think that
the reported problem may be caused by the duplication detection in
802.11 layer.

Matthew Dillon [Thu, 14 Jun 2007 02:55:27 +0000 (02:55 +0000)]
When getnewvnode() is called the vnode's v_type defaults to VNON.  Syncer
vnodes are also set to VNON and any vnode that is accessed without locking
whos v_type is VNON is probably in the middle of being initialized.  For
this reason the mountlist scan and vflush code typically ignores such
vnodes.

If a read error occurs while initializing a vnode, in particular if a hash
collision occurs or an I/O error occurs reading the inode, the vnode's
v_type was being left set to VNON.  Explicitly set it to VBAD for msdosfs
and ufs (other FS's probably need the same treatment) so the flush and
reclaim code can reuse the vnode.

This fixes 'dangling vnode' panics on unmount for filesystems which incur
I/O errors, such as when one pulls a USB memory stick out while it is
still mounted.
