SUNRPC: fix hang due to eventd deadlock...
Brian Behlendorf writes:
The root cause of the NFS hang we were observing appears to be a rare
deadlock between the kernel provided usermodehelper API and the linux NFS
client. The deadlock can arise because both of these services use the
generic linux work queues. The usermodehelper API run the specified user
application in the context of the work queue. And NFS submits both cleanup
and reconnect work to the generic work queue for handling. Normally this
is fine but a deadlock can result in the following situation.
- NFS client is in a disconnected state
- [events/0] runs a usermodehelper app with an NFS dependent operation,
this triggers an NFS reconnect.
- NFS reconnect happens to be submitted to [events/0] work queue.
- Deadlock, the [events/0] work queue will never process the
reconnect because it is blocked on the previous NFS dependent
operation which will not complete.`
The solution is simply to run reconnect requests on rpciod.

(which is all the current client has #defines for). The client then
later checks this bitmask and turns on the appropriate flags in the

This patch only currently checks to see if the server used the atime

for this). I'm not sure of what other fields the server could
reasonably use, but adding checks for others should be trivial.

- added cbe-oss-dev@ozlabs.org line for MAINTAINER file
- changed some in copyright comments
If there are no more comments, please apply for 2.6.23.

bonding / ipv6: no addrconf for slaves separately from master
At present, when a device is enslaved to bonding, if ipv6 is
active then addrconf will be initated on the slave (because it is closed
then opened during the enslavement processing). This causes DAD and RS
packets to be sent from the slave. These packets in turn can confuse
switches that perform ipv6 snooping, causing them to incorrectly update
their forwarding tables (if, e.g., the slave being added is an inactve
backup that won't be used right away) and direct traffic away from the
active slave to a backup slave (where the incoming packets will be
dropped).
This patch alters the behavior so that addrconf will only run on
the master device itself. I believe this is logically correct, as it
prevents slaves from having an IPv6 identity independent from the
master. This is consistent with the IPv4 behavior for bonding.
This is accomplished by (a) having bonding set IFF_SLAVE sooner
in the enslavement processing than currently occurs (before open, not
after), and (b) having ipv6 addrconf ignore UP and CHANGE events on
slave devices.
The eql driver also uses the IFF_SLAVE flag. I inspected eql,
and I believe this change is reasonable for its usage of IFF_SLAVE, but
I did not test it.
