cluster/afr: Remove eager-lock stub on finodelk failure

2014-04-02T17:50:32+00:00

Problem:
For write fops afr's transaction eager-lock init adds transactions
that can share eager-lock to fdctx list. But if eager-lock finodelk
fop fails the stub remains in the list. This could later lead to
corruption of the list and lead to infinite loop on the list
leading to a mount hang.

Fix:
Remove the stub when finodelk fails.

cluster/afr: refactor

2014-03-22T12:25:57+00:00

- Remove client side self-healing completely (opendir, openfd, lookup)
- Re-work readdir-failover to work reliably in case of NFS
- Remove unused/dead lock recovery code
- Consistently use xdata in both calls and callbacks in all FOPs

- remove unused variables and functions
- make code more consistent in style and pattern
- regularize and clean up inode-write transaction code
- regularize and clean up dir-write transaction code
- regularize and clean up common FOPs
- reorganize transaction framework code
- skip setting xattrs in pending dict if nothing is pending
- re-write self-healing code using syncops
- re-write simpler self-heal-daemon

cluster/afr: goto statements may cause exit before memory is freed.

2014-02-10T16:38:57+00:00

Memory is allocated for pump_priv and for pump_priv->resume_path, but if
an error is detected the references to that memory go out of scope and
the memory is never freed.

This patch assures that the memory is freed on error.

Patchset 2: These are Kaleb's recommended changes which, compared to my
            original fix, are more comprehensive and provide a more
            complete resolution to the memory leakage bugs in this
            function.  The bug reported by Coverity was limited to a
            single memory allocation.
