I've run across a peculiar buggy interaction of the NetBSD NFS
client and a Linux NFS server; I'm not sure where to lay the blame,
but I've only had the problem on NetBSD machines (lola and ringworld,
specifically).
I had mounted a file system from a Linux NFS server, and had
the following problems:
athena% ls -ali
ls: ..: Permission denied
total 8
1476838322 drwxrws--- 5 nathanw 6.170-te 1024 Dec 3 16:49 .
1476838323 drwxrws--- 2 nathanw 6.170-te 1024 Nov 29 15:36 CVSROOT
1476637297 drwxrws--- 2 nathanw 6.170-te 1024 Dec 3 16:42 antichess
1476838356 drwxrwxrwx 2 root 6.170-te 1024 Dec 3 16:49 test
athena% cd test
athena% ls -ali
ls: ..: Permission denied
total 2
1476838356 drwxrwxrwx 2 root 6.170-te 1024 Dec 3 16:49 .
athena% touch foo
touch: foo: Permission denied
athena% cd ..
..: Permission denied.
athena%
Essentially, lots of permission stuff seemed to be broken; I
don't know why it would prevent me from writing into a mode 777
directory under normal circumstances, or why stat would work for a
directory '.' but not the same directory as '..'.
I tried looking at the debugging output of the NFS server, but
I was unable to glean any useful information from it.
