remove_file: don't call rmdir if remove_file return failure
When deleting a directory, the directory should not be removed if the
file in the subdirectory fails to be deleted.
Background information:
When I tested the kernel using LTP (linux-test-project).I found the
mv command have some issue. The LTP test case use the mv command to
move the directory t1 in the cgroup file system to the /tmp directory.
becase files in the cgroup file system are not allowed to be removed.
so the mv reported "Permission denied", but I used the ls command to
view the results and found that the directory t1 had been removed
from the cgroup file system. For the same test case, I used the mv
tool in the GNU coreutils, and the directory t1 will not be removed.
the following testcase use busybox mv:
/ # mount -t cgroup -o cpu cgroup /cpu
/ # cd /cpu
/cpu # mkdir -p t1
/cpu # ls
cgroup.clone_children cpu.cfs_period_us cpu.stat t1
cgroup.procs cpu.cfs_quota_us notify_on_release tasks
cgroup.sane_behavior cpu.shares release_agent
/cpu # mv t1 /tmp
mv: can't remove 't1/cgroup.procs': Operation not permitted
mv: can't remove 't1/cpu.cfs_period_us': Operation not permitted
mv: can't remove 't1/cpu.stat': Operation not permitted
mv: can't remove 't1/cpu.shares': Operation not permitted

/cpu # ls
cgroup.clone_children cpu.cfs_period_us cpu.stat cgroup.procs
cpu.cfs_quota_us notify_on_release tasks cgroup.sane_behavior

This patch fixed it, don't call rmdir if remove_file return failure,
and under certain file systems, the mv could work normally.

sysklogd: add timestamp option to ignore message timestamps
Some syslog producers provide inconsistent timestamps, so provide an option
to ignore the message timestamps and always locally timestamp. In order to
implement this, invert the valid-timestamp check, but only use the timestamp
if this option is not enabled.
This is in line with what what other syslogd implementations do:
From sysklogd syslogd.c:
* Sun Nov 7 12:28:47 CET 2004: Martin Schulze <joey@infodrom.org>

ash: expand: Do not quote backslashes in unquoted parameter expansion
Upstream commit:
Date: Wed, 28 Mar 2018 18:37:51 +0800
expand: Do not quote backslashes in unquoted parameter expansion
Here is a better example:
a="/*/\nullx" b="/*/\null"; printf "%s\n" $a $b
dash currently prints
/*/\nullx
/*/\null
bash prints
/*/\nullx
/dev/null
You may argue the bash behaviour is inconsistent but it actually
makes sense. What happens is that quote removal only applies to
the original token as seen by the shell. It is never applied to
the result of parameter expansion.
Now you may ask why on earth does the second line say "/dev/null"
instead of "/dev/\null". Well that's because it is not the quote
removal step that removed the backslash, but the pathname expansion.
The fact that the /de\v does not become /dev even though it exists
is just the result of the optimisation to avoid unnecessarily
calling stat(2). I have checked POSIX and I don't see anything
that forbids this behaviour.
So going back to dash yes I think we should adopt the bash behaviour
for pathname expansion and keep the existing case semantics.
This patch does exactly that. Note that this patch does not work
unless you have already applied
https://patchwork.kernel.org/patch/
10306507/
because otherwise the optimisation mentioned above does not get
detected correctly and we will end up doing quote removal twice.

the end of the pattern which is now possible.

You're right. The proper fix to this is to ensure that nulonly
is not set in varvalue for $*. It should only be set for $@ when
it's inside double quotes.
In fact there is another bug while we're playing with $@/$*.
When IFS is set to a non-whitespace character such as :, $*
outside quotes won't remove empty fields as it should.
This patch fixes both problems.

POSIX used to require the current dash behaviour. However, you're
right that this is no longer the case.
This patch will remove the persistence of the variable assignment.
I have considered the exporting the variables during the function
execution but have decided against it because:
1) It makes the code bigger.
2) dash has never done this in the past.
3) You cannot use this portably anyway.

This necessitates switch from libc FILE api to a simple

The change which fixes the bug here is the deleting of

The fix is: we don't even _want_ to restore scrit fds,
we are perfectly fine with them being moved.
The only reason we tried to restore them is that FILE api
did not allow moving of FILE->fd.
