NFS: subdirectories not directories /KDL on file touch.

[kallisti5]

Mount nfs share:
mount_nfs 192.168.1.200:/frisky /chao
NFS files are present as expected in /chao/
Trying to navigate to any directory in /chao/ turns up empty directory in tracker.
Trying to navigate to any directory in /chao/ turns up "Not a directory"

Details below.

/chao> ls -la drwxrwxr-x 9 65534 65534 4096 Sep 27 17:56 . drwxrwxrwx 1 user root 0 Sep 27 17:59 .. drwxrwxrwx 2 65534 65534 4096 Sep 1 07:54 pictures

/chao> cd pictures/ sh: cd: pictures/: Not a directory

[kallisti5]

/chao> ls -la
drwxrwxr-x  9 65534 65534  4096 Sep 27 17:56 .
drwxrwxrwx  1 user  root      0 Sep 27 17:59 ..
drwxrwxrwx  2 65534 65534  4096 Sep  1 07:54 pictures

/chao> cd pictures/
sh: cd: pictures/: Not a directory

[kallisti5]

hitting tab does list the files in the nfs sub directory:
/chao> ls pictures/

whoops... touching a file on the nfs mount dir causes a KDL.. bt screenshot follows. I saw #3500 but I don't think this is the same issue as the KDL does not occur until modifications are made to the nfs mount. also the touch took a few seconds (10?) before the kdl occured.

[kallisti5]

KDL after touching a file on the root of the NFS share.

[kallisti5]

bumping to high as it is standard OS functionality that causes a KDL on every platform and is not limited to one user or piece of hardware. (#5053 closed as duplicate)

Little more info, after un-mounting the NFS share, the icon remains on the desktop and cannot be removed. Double-clicking icon results in no window or action, restarting tracker resolves this issue and the NFS icon disappears.

Fix subdirs under NFS

OK, I fixed the subdirectory problem, and have attached a patch (nfs_subdir.patch).

The KDL is not fixed, that is next on my list.

I think there is a memory leak when vnodes are freed as well. I need to investigate that further.

Still, with the attached patch, the NFS filesystem driver should be OK if you want a read-only filesystem.

Subdirectory patch applied in hrev35612, sorry for the delay!

[kallisti5]

whoo, can stream movies off of nfs shares now (including sub-directories). I call this one resolved. Any NFS bugs left can be opened in new tickets.

Ok !
