mainlining shenanigans
476af91933
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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
