The following reply was made to PR kern/132934; it has been noted by GNATS. From: Zachary Loafman <zachary.loafman@isilon.com> To: bug-followup@FreeBSD.org, msch@snafu.de Cc: Subject: Re: kern/132934: [nfs] Cancel of a NFS-lock fails repeatedly Date: Fri, 8 May 2009 11:48:08 -0700 I scrounged up an HP-UX client at Isilon and testing it against the kernel NLM code using the flock test in tools/regression/file/flock. It passes with flying colors: # ./flock /mnt/zl/hpux; echo $? 1 - F_GETLK on unlocked region: SUCCEED 2 - F_SETLK on locked region: SUCCEED 3 - F_SETLKW on locked region: SUCCEED 4 - F_GETLK on locked region: SUCCEED 5 - F_SETLKW simple deadlock: SUCCEED 6 - F_SETLKW complex deadlock: SUCCEED 7 - F_SETLK shared lock on exclusive locked region: SUCCEED 8 - F_SETLK shared lock on share locked region: SUCCEED 9 - F_SETLK exclusive lock on share locked region: SUCCEED 10 - trying to set bogus pid or sysid values: SUCCEED 12 - F_SETLKW on locked region which is then unlocked: SUCCEED 13 - F_SETLKW on locked region, race with owner: SUCCEED 14 - soak test: SUCCEED 15 - flock(2) semantics: SUCCEED 0 # uname -a HP-UX cqhp01 B.11.31 U ia64 3687355900 unlimited-user license I'm going to try some other experiments now, but if you have any hints on a tighter repro, I'd appreciate it.
