Al Viro pointed out that I broke some acl functionality... * ACLs could not be fully removed * posix_acl_chmod would be called while the old ACL was still cached * new mode propagated to orangefs server before ACL. ... when I tried to make sure that modes that got changed as a result of ACL-sets would be sent back to the orangefs server. Not wanting to try and change the code without having some cases to test it with, I began to hunt for setfacl examples that were expressible in pure mode. Along the way I found examples like the following which confused me: user A had a file (/home/A/asdf) with mode 740 user B was in user A's group user C was not in user A's group setfacl -m u:C:rwx /home/A/asdf The above setfacl caused ls -l /home/A/asdf to show a mode of 770, making it appear that all users in user A's group now had full access to /home/A/asdf, however, user B still only had read acces. Madness. Anywho, I finally found that the above (whacky as it is) appears to be "posixly on purpose" and explained in acl(5): If the ACL has an ACL_MASK entry, the group permissions correspond to the permissions of the ACL_MASK entry.
