by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git mount-cleanups-testing
commit 572d8ce20aa06a907c09c721bdaa4cbbe3753736
Author: Eric W. Biederman <ebiederm(a)xmission.com>
AuthorDate: Thu Dec 20 15:55:56 2018 -0600

vfs: Simplify security mount option processing
Reduce the security hooks for processing mount options from
sb_copy_data, sb_parse_opts_str, and sb_set_mnt_opts to just
sb_mnt_opts.
Use split_options that iterates through all of the mount options and
pulls out the security mount options.
Use join_options that iterates through split out options and forms
a single mount option string again.
Add a hard coded copy of the security mount options and always parse
them out, so that there is no a chance of a filesystem implementing one
of these options by accident.
Using split_options strikes a happy medium between the logic that
selinux used to parse mount options and the logic most it not all
filesystems have used to parse mount options. Ordinary filesystems
separate mount options on a comma. The code in selinux will ignore
commas if they are enclosed in quotation marks. The code in selinux
would process quotation marks anywhere. The code in split_options
only looks for quotaion marks after an equal sign. This difference in
implementation will not result in a difference in accepted options
because selinux would look for options before removing the quotation
marks. Which resulted in selinux never accepting any options with
embedded quotation marks. Embedded quotation marks were only accepted
and stripped from option values.
