>Description:
There are multiple NFS client bugs that need to be fixed in the
FreeBSD 7.4-RELEASE code base that have been fixed in 8-STABLE, 8.3-RELEASE
9-STABLE and HEAD. Here is a list of the relevant MFCs
194358,230394,230441,230489,230552,232116,232420 and r227059
This code has now been in 7-STABLE for two weeks .
>How-To-Repeat:
Running multiple 7.4-RELEASE servers that uses NFS mount directories
there exists two nasty issue. If client a reads a file o r directory as client
b changes the file or directory , in a short enough amount of time, client a
never sees the file or directory changed and it will see old data and
attributes for this object until it attempts to write to it . Secondly when
multiple NFS client using lockd, are under a moderate work load the client will
crash due to a rpc bug brought about by high rates of locking.
>Fix:
The following MFCs need to be merged into the 7.4-RELEASE branch. MFCs
194358,230394,230441,230489,230552,232116,232420 and r22
