The implementation using the new FD based mount kernel API (ie.,
fsconfig/fsopen) uses MNT_ERR_APPLYFLAGS for failed mount_setattr(2)
calls, which involves more mount attributes (eg., MOUNT_ATTR_RDONLY,
MOUNT_ATTR_NOSUID, etc.) in addition to the MS_PROPAGATION flags (eg.,
MS_SHARED, MS_UNBINDABLE, etc.).
Note that mount_setattr(2) is part of the new FD based mount kernel API,
and is not used by the classic mount(2) based version.

dmesg: -r LOG_MAKEPRI needs fac << 3
Submission to Project: util-linux
Open Incident: #2325 at github.com/util-linux/util-linux/issues/2325
Component: util-linux/sys-utils
File: dmesg.c
Code level patch applied against: 2.39 - latest code pulled from
git.github.com:util-linux/util-linux.git
BUG: The facility field passed to macro from /usr/include/sys/syslog.h
LOG_MAKEPRI(fac, pri) by dmesg -r needs to have fac argument
shifted 3 bit to the left to return a valid raw valid. The lower
3 bits for a raw value are used by the loglevel priority (pri)
field, so the facility bits can only occupy the bits above the
bits used to hold the pri field value.
The dmesg -r command produces the incorrect output for the raw value
for the or'ed combination of the facility | loglevel priority that gets
produced by the LOG_MAKEPRI macro. That macro is defined as:
#define LOG_MAKEPRI(fac, pri) ((fac) | (pri))
which is defined in the current glibc code in /usr/include/sys/syslog.h
and is used only in the dmesg -r (raw output option) command to form the
raw value for facility or'ed with loglevel priority and displayed as:
<#>[#######.######] ...
where the # in <#> contains the output from the LOG_MAKEPRI macro.
The lower 3 bits are reserved for the loglevel priority 0-7
and the bits above that are for the facility value, so the facility
index should be shifted to the left three bits and or'ed with the
loglevel priority.
In the glibc file: /usr/include/sys/syslog.h the macro LOG_MAKEPRI is
defined as:
#define LOG_MAKEPRI(fac, pri) ((fac) | (pri)
and returns the wrong facility and loglevel priority values, ideally it
should be defined as:
We checked with glibc developement and the LOG_MAKEPRI macro is correct
as is and can't be changed as it used by *BSD as is so the solution for
dmesg -r is to shift the facility index left by 3 bits as input to the
LOG_MAKEPRI macro. That is what glibc development recommended.
(For reference, see glibc bugzilla Bug 30563)
We can front end the LOG_MAKEPRI macro with a macro that shifts the
facility by the needed 3 bits which we've added to dmesg.c:
-bash-4.2# dmesg -r | grep "Test Message Facility"
<7>[ 495.317239] Test Message Facility 8 Loglevel 6
<7>[ 503.340779] Test Message Facility 8 Loglevel 7
<7>[ 643.374764] Test Message Facility 24 Loglevel 6
<7>[ 657.165117] Test Message Facility 24 Loglevel 7
However, if we run the dmesg -r command using the new front end macro
LOG_RAW_FAC_PRI(fac, pri) we do get the correct output:
Here is the corrected dmesg -r output:
-------------------------------------
-bash-4.2# dmesg -r | grep "Test Message Facility"
<14>[ 495.317239] Test Message Facility 8 Loglevel 6
<15>[ 503.340779] Test Message Facility 8 Loglevel 7
<30>[ 643.374764] Test Message Facility 24 Loglevel 6
<31>[ 657.165117] Test Message Facility 24 Loglevel 7
shifting the facility index value by 3 bits in the LOG_RAW_FAC_PRI macro
provides the correct ouput as shown. All the other commands produce the
same output so now they are all in agreement.

Add `--user-parent` option to nsenter
When this option is used nsenter will fetch the parent user
namespace from any namespace file descriptors available.
It can be combined with existing `--user` option in which case
the parent user namespace will be fetched from the user namespace
and replace it.
The usecase of this option is when a user namespace that owns
the other type namespaces we want to switch to is not actually
bound to any process. Without using ioctl it is impossible to
acquire namespace file descriptor. For example, bubblewrap
`bwrap` command creates unbinded user namespace when `--dev`
option is used.

libmount: fix sync options between context and fs structs
Since v2.39 libmount prefers "struct libmnt_optlist" to keep mount options
rather than the original "struct libmnt_fs". This is problem if the
"fs" struct is defined and maintained outside the context.
The library has already a way how to sync "fs" and "optlist", but this
needs to be improved and used more widely. Changes:
* force "fs" from context to always read options from "optlist"
* copy options from "fs" to "optlist" in mnt_context_set_fs()
* internally redirect mnt_fs_* API for options to "optlist" if optlist
defined
* add simple test to make sure options from different sources are
always merged together
