I disagree... Same lib call, same device, works before your patch, does
not after... You may call it a bug that shouldn't be relied on, but
that's for sure an API breakage.

Ok, you told me from where it comes from.
How different is it of any other tool that uses libblkid doing
open(); blkid_new_probe(); blkid_probe_set_device();
Instead of calling blkid_new_probe_from_filename() directly?
Because this still can easily access a private device.

We don't do anything with udev. We use libblkid to query device's
geometry to properly configure the filesystem to be initialized there.
If blkid_new_probe_from_filename() fails, mkfs abort. It's up to the
user to pass the right device.

It seems that this fix doesn't handle the case where -- is used as an
argument to an option. For example, `script -I --` before v2.42 would
interpret -- as an argument to -I, but the pre-scanning in that PR would
break it.
The value can come from a variable, e.g. `script -I "$VAR"` and `script
--log-in "$VAR"` will usually work, but break if $VAR is --. Similarly,
`script "-I$VAR"` will usually work, but break if $VAR is the empty
string. The only approach without special cases seems to be `script
"--log-in=$VAR"`, but it doesn't seem to be very popular.

Hi
The main missed concept here is - this is not breaking any API.
The concept of private DM device is to be a device that is not being touched
by libblkid. So this was a pure bug in the libblkid code when there was a
code path skipping check (and actually doing this check after opening private
device).
And actually IMHO there is a bigger issue - xfs tools are actually relying
too much on content of udev DB - this DB is by design unreliable - so it's
likely good for some quick checking - but i.e. in lvm2 - we always do a real
disk read - udevDB is only advisory.

Thanks for the details. Indeed I noticed sysfs_devno_is_dm_private()
skipping 'stratis-1-private' suffixed devices, but to be honest, their
functionality is opaque to me, I don't really know what they mean or how
they are used.
I got a report that mkfs.xfs stopped working for them, and my investigation
led to this subtle behavior change in blkid_new_probe_from_filename().
So, IIUC what you're saying, stratis shouldn't be using devices they
flag as private the way they are using, so I agree, and perhaps their
understanding of what a private device means is wrong and not using the
API properly.
On the other hand though -- playing The Devil's Advocate a bit --, this
is still a subtle API break and I don't think your patch is the right
way to fix the race you're seeing.
I honestly couldn't find any information about it, whether
blkid_new_probe_from_filename() could be used or not with private
devices, the only thing I really see (from a user perspective) was the
library call not working as before.
Also, reading what you explained above regarding the usage, I think I
was right when I said this is not the right way to fix the race you
mentioned. Because the race is still there, it is now just hidden for
LVM's specific use case.
Quoting libblkid documentation for blkid_new_probe_from_filename():
"
This function is same as call open(filename), blkid_new_probe()
and blkid_probe_set_device(pr, fd, 0, 0).
"
This was exactly how I "fixed" xfsprogs to allow Stratis behavior to
continue the way it is. Which by your explanation above is incorrect,
as is the same sequence call that you mentioned that should not be
allowed... open() the device then probe_set_device()... Which tells me
that any libblkid user following this same sequence is fundamentally
broken.
So, although I agree with you that Stratis is using libblkid incorrectly,
I still think this patch is wrong, as it changes the library's behavior
to fix a problem in LVM (if there is where the race was), and not some
inherent library problem. If, no user can use libblkid to query into a
private device, then the above lib call sequence wasn't supposed to work
either, and perhaps then, blkid_probe_set_device() should actually fail
in a private device.
Again, I just looked into the libblkid low-level implementation today,
but it doesn't seem to be the library's job to be responsible for a race
between open() and ioctl(DM_DEVICE_REMOVE).

Carlos

Hi
So I'm not sure how it happened that Stratis kind of 'reuses' libdm private
logic we have embedded into util-linux - but something wrong is likely
happening on Stratis side here.
For libdm & util-linux - there is basic principle - when udev should be
scanning a 'DM' device that is supposed to be private - in our case it's
uuid with "LVM-" prefix and "-anysuffix: - such device is supposed to be
NOT touched by any udev rule logic - it's private - so nothing should be
'randomly' opening a device at unpredictable moments..
Somehow it seems Stratis selected to use similar notion (at least when I look
there in sysfs_devno_is_dm_private() - there is check for uuid:
"stratis-1-private"
> This change broke Stratis project and xfsprogs.

If the private is not meant to be private - just drop:
} else if (strncmp(id, "stratis-1-private", 17) == 0) {
rc = 1;
}

Please don't try to break original LVM logic which was the main reason why
sysfs_devno_is_dm_private() even exists in the first place.

Yes - but there is higher logic behind - private 'device' is private and
should not be randomly opened by any tool.

I think main problem is that Stratis mangled 'private' meaning in some way.
So let's fix Stratis instead of breaking correct logic in util-linux made for
lvm2.

* [PATCH RFC 0/2] Fix API breakage in libblkid
From: cem @ 2026-04-08 10:35 UTC (permalink / raw)
To: kzak; +Cc: util-linux, zkabelac, amulhern
From: Carlos Maiolino <cem@kernel.org>
Patch d05a84b22e54 ("libblkid: check for private DM device before open")
broke blkid_new_probe_from_filename() API.
Before the patch users were able, via the low-level API, to open and
create blkid probes via the device's filename even from private
device-mapper devices.
This change broke Stratis project and xfsprogs.
xfsprogs uses blkid_new_probe_from_filename() to gather topology
information from the device, and the above mentioned change now prevents
it to be done on device-mapper private devices, as Stratis does by
attempting to initialize a XFS filesystem on it.
Quoting the patch description:
"
blkid_new_probe_from_filename() opens the device before calling
blkid_probe_set_device(), which checks sysfs_devno_is_dm_private()
and sets BLKID_FL_NOSCAN_DEV. But the open() itself bumps the
kernel open count, so a concurrent DM_DEVICE_REMOVE ioctl sees
EBUSY even though blkid never actually probes the device.
"
I don't think the last statement here is correct.
blkid_probe_set_device() marks the probe as BLKID_FL_NOSCAN_DEV, but it
does not error out, so, for low-level API calls, we simply ended up
with a probe with BLKID_FL_NOSCAN_DEV set. But the call succeeded and we
ended up with a probe to use and query device's information.
As far as I understood it, the patch aimed to close a possible race
window when issuing a DM_DEVICE_REMOVE ioctl() to the same device being
probed by blkid_new_probe_from_filename().
Regarding the race window which this patch, at least for the low-level
API users, this seems to be something that should be dealt in the user's
side, not within the library. But I didn't dig into the details of the
aforementioned race.
Please take the above with a grain of salt though, we've been using
libblkid for ages, but I never actually looked into the implementation
until today, so, hopefully I did get the details right.
As for xfsprogs, I have a patch which 'fixes' it replacing
blkid_new_probe_from_filename() by blkid_probe_set_device(), but this is
just taping over the root cause, which is the API breakage.

I have no strong opinion about it. For me, as a user, it is important
to have data in man pages structured and easy to navigate without
reading large paragraphs.
As a maintainer, I'd like to keep translators happy, which means
having text in chunks that are readable and in an easy-to-manage

I have committed only the statfs_magic.h part to make it more portable,
pidfd-utils.c needs to be marked as Linux-only as it's based on things

Subject: [PATCH] pidfd-utils: include correct struct statfs header for darwin
Fixes the build on Darwin since struct statfs is in sys/mount.h
and sys/vfs.h doesn't even exist. Just conditionally include all the
headers.

About su(1), in the meantime a Debian user filed a bug that su(1)
regressed, too: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1132610
To quote:
| The command 'su <user> -s /bin/sh -c "echo foo"' now runs
| 'bash -s /bin/sh -c "echo foo"' instead of just
| '/bin/sh -c "echo foo"', which causes bash to hang reading commands
| from stdin.
|
| This breaks suspend via in my setup which uses
| /usr/share/acpi-support/screenblank from the acpi-support package:
|
| if pidof xscreensaver >/dev/null; then
| su "$XUSER" -s /bin/sh -c "xscreensaver-command -throttle"
| fi
And:
| Actually the su man page says:
|
| SYNOPSIS
| su [options] [-] [user|UID [argument...]]
|
| So one could argue that the acpi-support script's use of
| 'su "$XUSER" -s /bin/sh -c "..."' is buggy.
| 'su -s /bin/sh "$XUSER" -c "..."' works.
|
| However, the acpi-support scripts (/usr/share/acpi-support/screenblank
| and /etc/acpi/lid.sh, have not checked others) worked with previous versions
| of util-linux.
It would seem that various versions of passing the command to su(1)
are in use, and constraining them will break all these usages.

I only had a quick look at runuser --help and the man page, and
while it seems to imply that "-" and "-l" are supposed to do the
same thing, I doubt this is what was intended and/or the actual
implementation.
At this point I also doubt that even if the documentation supports
the new behaviour it's worth breaking all the existing users.

Hey Chris,
The issue is indeed caused by the mentioned commit ac0147f, however
the change is necessary for proper functioning of su(1). Nevertheless, I
have created a PR that separates the short option strings used for su(1)
and runuser(1) as we need a different scanning mode for the former.
I have also added regression tests for runuser(1) and slightly improved
the one for su(1) so we can catch regressions earlier.
With the patch the issue with runuser should be fixed. Can you please
validate this ?
PR: https://github.com/util-linux/util-linux/pull/4185
Edit:
After taking a closer look at the runuser(1) man page it seems to me that
the actual documented syntax implies that options should always be put
before the username and potential arguments that are to be passed to the
shell or defined command. This aligns with the usage of su(1) and seems
more coherent. Let's see what Karel thinks about this :D

Christian Goeschel Ndjomouo

It appears to work when placing the options in a different order,
f.e. this works:
# MY_VAR=foo runuser -w MY_VAR -l root -c env
Notably the placement of the -l option and the username seem to be
the problem.
I'll note that `MY_VAR=foo runuser -l root -w MY_VAR -c env` worked in 2.41.
Maybe ac0147fd14b348097c82c1c89a5417b582e26bad broke this?

| su: pass arguments after <user> to shell
|
| The su(1) manpage describes how the arguments after <user>
| are passed to the invoked shell. However this is empirically
| wrong, as option flags after <user> are interpreted by su(1)
| and will eventually never be passed or yield an error that
| terminates the program due to an unrecognized option flag.
|
| To fix this we can change getopt(3)'s scanning mode with a '+'
| prefixed to 'optstring', this will make it so that getopt(3)
| stops processing argv elements on the first occurrence of a
| non-option argument, e.g. '-' or '<user>'.
|
| Additionally, if the argument that directly follows '-' is an
| option flag, su(1) will assume that this argument and the ones
| that follow, are to be passed to a shell invoked by the root user.

* [ANNOUNCE] util-linux v2.42
From: Karel Zak @ 2026-04-01 11:30 UTC (permalink / raw)
To: linux-kernel, linux-fsdevel, util-linux
The util-linux release v2.42 is now available at
http://www.kernel.org/pub/linux/utils/util-linux/v2.42
Feedback and bug reports, as always, are welcomed.
Karel
util-linux 2.42 Release Notes
=============================
Security fixes:
CVE-2026-27456 - mount(8) TOCTOU symlink attack via loop device.
The SUID mount follows symlinks when resolving loop backing file
paths. On systems where non-root users are permitted to mount loop
devices (via 'user' option in fstab), this allows access to
arbitrary files.
CWE-190 - Integer overflow in libblkid parse_dos_extended().
A crafted MBR disk image can cause uint32_t wraparound in EBR
chain processing, causing reported partitions to not match the
on-disk layout. Tools like udisks may then register a partition
at logical sector 0.
Release highlights:
The NTFS mount type (kernel FS driver) can be changed by the compile option
--with-ntfs-mounttype=, the default is ntfs3.
login(1) now uses the original FQDN (as specified by "-h <host>") to configure
the PAM RHOST item. All previous versions used the hostname without domain.
This may affect users who use login(1) for remote access (rlogin, rsh) and
pam_access to define access rules. (Don't worry, if you still use rlogin then
security is already irrelevant for you.)
login(1), if configured with LOGIN_SHELL_FALLBACK in login.defs, can fall back
to another valid shell from /etc/shells if the user's configured shell is
inaccessible due to administrative errors.
agetty reads issue file(s) in a way compatible with libeconf and systemd,
hermetic-usr and drop-ins are now supported. For more details see
https://uapi-group.org/specifications/specs/configuration_files_specification/
agetty uses netlink to get network interface information for issue file output.
The libsmartcols-based tools with JSON support can now produce additional JSON
formats. The output format may be changed by LIBSMARTCOLS_JSON={lines,compact}
environment variable.
column(1) now supports colors.
New command copyfilerange(1) to copy file ranges using the copy_file_range()
syscall.
New command getino(1) to print the unique inode number associated with a
process file descriptor or namespace for a given PID.
fadvise(1) now supports --fd to address a file by file descriptor rather than
by path.
fallocate(1) now supports --report-holes to scan the file and report the
distribution of holes.
A significant performance regression has been fixed in hardlink(1).
hardlink(1) now supports FIEMAP-based sparse file optimization.
kill(1), waitpid(1) and nsenter(1) now support the PID:INO convention to
precisely address processes.
mount(8) now supports --beneath to atomically replace a filesystem at a
mountpoint.
mount(8) now supports --exclusive to ensure that the filesystem is mounted as a
unique instance and that the superblock is not reused by the kernel.
libmount now reads filesystem information from udevd (with fallback to classic
libblkid-based detection). This feature can be disabled by
--disable-libmount-udev-support.
setarch(8) now supports --pid to show the personality of a specified process.
The pager support for tools like "dmesg -H" has been improved to work better
with signals.
losetup(8) now supports --remove to remove a loop device node from the system.
lsblk(8), lslocks(8), lsmem(1) and lsclocks(1) support <NAME>_COLUMNS
environment variable to specify output columns as an alternative to --output.
lsfd(1) now supports new UNIX.IPEER, PACKET.PROTOCOL.RAW and TUN.DEVNETNS
columns.
setpriv(1) now supports landlock via --landlock-access and --landlock-rule
options.

* [ANNOUNCE] util-linux v2.41.4
From: Karel Zak @ 2026-04-01 11:30 UTC (permalink / raw)
To: linux-kernel, linux-fsdevel, util-linux
The util-linux release v2.41.4 is now available at
http://www.kernel.org/pub/linux/utils/util-linux/v2.41
This is a security maintenance release addressing:
CVE-2026-27456 - mount(8) TOCTOU symlink attack via loop device.
The SUID mount follows symlinks when resolving loop backing file
paths. On systems where non-root users are permitted to mount loop
devices (via 'user' option in fstab), this allows access to
arbitrary files.
CWE-190 - Integer overflow in libblkid parse_dos_extended().
A crafted MBR disk image can cause uint32_t wraparound in EBR
chain processing, causing reported partitions to not match the
on-disk layout. Tools like udisks may then register a partition
at logical sector 0.
Feedback and bug reports, as always, are welcomed.
Karel

The typo was introduced in commit a2752fe270, three months ago.
(The comma is not in same sentence in the next string either.)
