fstab:
//rhel73/myshare/sub/path /mnt cifs
after mount in mountinfo:
# grep cifs /proc/self/mountinfo
47 39 0:40 /sub/path /mnt rw,relatime shared:60 - cifs //rhel73/myshare/sub/path ...
^^^^^^^^^
or:
# grep cifs /proc/self/mountinfo
47 39 0:40 / /mnt rw,relatime shared:60 - cifs //rhel73/myshare/sub/path ...
^
That is so since on kernel cifs code, cifs_get_root (which returns the
entry associated with mnt_root) return s_root if
CIFS_MOUNT_USE_PREFIX_PATH is set, no questions asked.
This situation can occurr often on CIFS mounts, as CIFS servers limit
frequently scope of access to the root path.

The "Further details" sentence in the PID namespace section got merged
with the surrounding text; this patch moves it to the end, to match
the other namespace sections, and adds the missing clone(2) reference.

Now sfdisk stops everything on I/O error when moving data. It seems
better to report the error to user and continue as it's better to have
one bad sector in the partition than inconsistent all partition.

Before ecfeae90a2 ("libmount: Ensure utab.lock mode 644"), you could do
something like:
irc:/tmp umount --version
umount from util-linux 2.27.1 (libmount 2.27.0: selinux, assert, debug)
irc:/tmp mkdir foo bar
irc:/tmp unshare -Urm
irc:/tmp mount --bind foo bar
irc:/tmp umount bar
irc:/tmp echo $?
0
However, afterwards, you get:
/tmp unshare -Urm
/tmp mount --bind foo bar
/tmp umount bar
umount: /tmp/bar: filesystem was unmounted, but failed to update userspace mount table.
Because of the chmod failing:
fchmod(3, 0644) = -1 EPERM (Operation not permitted)
Let's figure out whether the chmod is necessary before doing it, and only
do it if it is necessary. This won't fix cases where the system is already
broken, but at least on healthy systems umount will behave as before.

include: add remove_entry() to env.h

more: fix moving backwards so that it can reach begining of the file
more: use getopt_long() to parse options
more: remove underlining related code
more: fix SIGSTOP and SIGCONT handling
more: make execute() more robust and timely
more: target all standard streams when calling fflush()
more: remove kill_line() in favor of erase_prompt()
more: avoid defining special characters locally
more: use off_t and cc_t to clarify what variables attempt to represent
more: do not reset parent process terminal in execute()
more: use single exit path to ensure resource freeing is unified
This PR fixes an off by one in `strncmp(dev->bid_name, "/dev/mapper/", 11)` check. The `"/dev/mapper/"` string literal has a length of 12 and without this fix paths like `"/dev/mapperSOMETHING"` would also be accepted.
Moving backwards has worked fine until reaching start of file. At that
point more printout had one line too much in output causing more seemingly
never to be able to reach the start. That is now fixed, with clean ups to
skip_backwards() making it less confusing.

This commit also includes fix to how initial skip lines and search are
instructed in the code. Earlier version was pretty close impossible to make
work with getopt_long() and had minor flaw - if both initial skip lines and
search were defined at the same time the skipping did not happen. That is
now corrected.

When suspending only the more process. Sending signal to process group

SIGCONT is expected, and it needs to ensure output terminal settings are
what more needs.

Two new options are added: `--map-user=<uid>` and `--map-group=<gid>`
for custom user and group mappings respectively. These are just
generalizations of the existing `--map-root-user` and
`--map-current-user` options.
As a side effect of this commit, specifying both `--map-root-user` and
`--map-current-user` no longer causes an error. Instead, the last
occurrence takes precedence.

Currently, umount /foo results in a statfs("/foo") call, which triggers
autofs. This can create another mountpoint on /foo, which is then unmounted
later instead of the actual /foo at the time umount was called.
This is especially an issue for umount -R /bar, which just fails with
-EBUSY as the accidental mountpoint is never accounted for and so it tries
to umount /bar before /bar/someautofs.
Replace the direct statfs call with open(path, O_PATH) + fstatfs, which sees
the autofs mount directly, without triggering it.
