- Uhh, I don't want to cast any doubt on the perfection of Sun code, but
- this description of a SunOS patch might be of interest:
-
- Patch-ID# 100075-08
- Keywords: lockd, rpc.lockd, file locking
- Synopsis: SunOS 4.1;4.1.1;4.1.2; lockd jumbo patch
- Date: 25/Mar/92
-
- <stuff deleted>
-
- Problem Description:
-
- i) klm protocol was changed but the rpc number was not.
-
- ii) Shared or exclusive lock relative to EOF does not work correctly.
-
- iii) Deadlock is not detected when locking over NFS.
-
- iv) Downgrade of lock does not grant other read locks.
-
- v) Panic "corrupt file lock list" might occur.
-
- vi) rpc.lockd does not release memory allocated and grows in size.
-
- vii) When doing "region locking" some regions do not get properly unlocked.
-
- viii) Granting of locks not working correctly when local and remote locks
- on same file are used at the same time.
-
- ix) Unlock that is interrupted by signal could leave the file as being locked
- by a process that does not exist.
-
- x) Core dump of rpc.lockd when unlocking in lm_unlock_region.
-
- xi) When server is rebooted locks are not reclaimed correctly.
