| |
I have about 9 NFS client test cases I regularly try because of recurring bugs. The three problems I mailed about 2.3.18ac5 are also present in 2.2.13pre9. For the 9 test cases 2.213pre9 and 2.3.18ac5 seem compatible. Summary of problems:
1 Redirecting I/O of setuid programs to NFS mounted FS mostly fails because of the wrong credentials being passed to the server.
2 Stale file handle problem:
sleep 10000 >file & // client rm file;date >file // server ls -l file // client again ls: file: Stale NFS file handle
3 Negative dentry caching cannot be disabled.
IMO (1) should be fixed; it can't be that difficult because many ac kernels don't have this problem. This bug is frequently recurring. Maybe I'll fix it when I can find some spare hours.
(2) is difficult for me to estimate but this bug is annoying at times.
(3) As I see it there are two possible solutions to handle this neat feature when it is unwanted: put it under the "noac" or other existing mount options regarding attribute caching ("acregmin=0" would work out best for me but not necessarily for others). The alternative which is best IMO (but not acceptable for 2.2.x I guess) is to create a new mount option. This would also permit lengthening the negative dentry life time for those who want it.
