[Pvfs2-developers] pvfs2-rm and sticky bit on 'root' directory

[David Metheny]

I pretty sure sticky bit isn't supported in PVFS2 generically, only
implemented at the root "/" directory, and permission checking for the
sticky bit implemented on the client side VFS layer. Should the sticky bit
on "/" level be considered in the mix for permissions for pvfs2 command line
utilities, namely pvfs2-rm?  For the example below, rmdir commands with
userB through the VFS layer fail for "rmdir /mnt/datagrid0002/client03", but
issuing a "pvfs2-rm /mnt/datagrid0002/client03" command with userB, the
permissions pass, due to the write permissions for 'others' on the parent
directory, and client03 is deleted. Removing the write access for others and
both VFS and pvfs2-rm behave similarly, although the error message from
pvfs2-rm seems a bit generic (PVFS_sys_remove: No such file or directory
(error class: 0)). 

 

ls -l /mnt

drwxrwxrwt    1 root     root         4096 Mar 11 11:47 datagrid0002

 

ls -la /mnt/datagrid0002/

drwxrwxrwt    1 root     root         4096 Mar 11 11:47 .

drwxr-xr-x    1 userA    userA        4096 Mar 11 11:47 client03

 

Thanks,

David
