2011-11-11nfsd4: ignore WANT bits in open downgradeJ. Bruce Fields
commit c30e92df30d7d5fe65262fbce5d1b7de675fe34e upstream. We don't use WANT bits yet--and sending them can probably trigger a BUG() further down. Signed-off-by: J. Bruce Fields <bfields@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-11-11nfsd4: fix open downgrade, againJ. Bruce Fields
commit 3d02fa29dec920c597dd7b7db608a4bc71f088ce upstream. Yet another open-management regression: - nfs4_file_downgrade() doesn't remove the BOTH access bit on downgrade, so the server's idea of the stateid's access gets out of sync with the client's. If we want to keep an O_RDWR open in this case, we should do that in the file_put_access logic rather than here. - We forgot to convert v4 access to an open mode here. This logic has proven too hard to get right. In the future we may consider: - reexamining the lock/openowner relationship (locks probably don't really need to take their own references here). - adding open upgrade/downgrade support to the vfs. - removing the atomic operations. They're redundant as long as this is all under some other lock. Also, maybe some kind of additional static checking would help catch O_/NFS4_SHARE_ACCESS confusion. Signed-off-by: J.

2011-11-11nfsd4: stop using nfserr_resource for transitory errorsJ. Bruce Fields
commit 3e77246393c0a433247631a1f0e9ec98d3d78a1c upstream. The server is returning nfserr_resource for both permanent errors and for errors (like allocation failures) that might be resolved by retrying later.

2011-08-04nfsd4: fix file leak on open_downgradeJ. Bruce Fields
commit f197c27196a5e7631b89e2e92daa096fcf7c302c upstream. Stateid's hold a read reference for a read open, a write reference for a write open, and an additional one of each for each read+write open. The latter wasn't getting put on a downgrade, so something like: open RW open R downgrade to R was resulting in a file leak. Also fix an imbalance in an error path.

2011-02-14nfsd4: acquire only one lease per fileJ. Bruce Fields
Instead of acquiring one lease each time another client opens a file, nfsd can acquire just one lease to represent all of them, and reference count it to determine when to release it. This fixes a regression introduced by c45821d263a8a5109d69a9e8942b8d65bcd5f31a "locks: eliminate fl_mylease callback": after that patch, only the struct file * is used to determine who owns a given lease. But since we recently converted the server to share a single struct file per open, if we acquire multiple leases on the same file from nfsd, it then becomes impossible on unlocking a lease to determine which of those leases (all of whom share the same struct file *) we meant to remove.

when callback is generated in NFSv4 server, it doesn't set the source address. When an alias IP is utilized on NFSv4 server and suppose the client is accessing via that alias IP (e.g. eth0:0), the client invokes the callback to the IP address that is set on the original device (e.g. eth0).
