* tests: disable lock_revocation.t on NetBSDRaghavendra Talur2016-08-311-0/+1
| | | | | | | | | | | | | | | This has been consistently causing hangs in NetBSD machines. I have not been able to debug the issue and we have merge deadline for 3.9. It would be better to disable this for now.

* features/locks: Add lock revocation functionality to posix locks translatorRichard Wareing2016-07-181-0/+52
Summary: - Motivation: Prevents cluster instability by mis-behaving clients causing bricks to OOM due to inode/entry lock pile-ups. - Adds option to strip clients of entry/inode locks after N seconds - Adds option to clear ALL locks should the revocation threshold get hit - Adds option to clear all or granted locks should the max-blocked threshold get hit (can be used in combination w/ revocation-clear-all). - Options are: features.locks-revocation-secs <integer; 0 to disable> features.locks-revocation-clear-all [on/off] features.locks-revocation-max-blocked <integer> - Adds monkey-locking option to ignore 1% of unlock requests (dev only) features.locks-monkey-unlocking [on/off] - Adds logging to indicate revocation event & reason Test Plan: First you will need TWO fuse mounts for this repro. Call them /mnt/patchy1 & /mnt/patchy2. 1. Enable monkey unlocking on the volume: gluster vol set patchy features.locks-monkey-unlocking on 2. From the "patchy1", use DD or some other utility to begin writing to a file, eventually the dd will hang due to the dropped unlocked requests. This now simulates the broken client. Run: for i in {1..1000};do dd if=/dev/zero of=/mnt/patchy1/testfile bs=1k count=10;done' ...this will eventually hang as the unlock request has been lost. 3. Goto another window and setup the mount "patchy2" @ /mnt/patchy2, and observe that 'echo "hello" >> /mnt/patchy2/testfile" will hang due to the inability of the client to take out the required lock. 4. Next, re-start the test this time enabling lock revocation; use a timeout of 2-5 seconds for testing: 'gluster vol set patchy features.locks-revocation-secs <2-5>' 5. Wait 2-5 seconds before executing step 3 above this time. Observe that this time the access to the file will succeed, and the writes on patchy1 will unblock until they hit another failed unlock request due to "monkey-unlocking".
