Currently with FileDescriptorStorePreserve=yes the FD store is kept around
regardless of what happens to a unit, which is useful in many cases. But in
some cases, for example when complex services crash horribly, it's hard to
reason about what was in the intermediate state, and it's better to start
fresh.
Add a new 'on-success' option for the FileDescriptorStorePreserve= setting
that keeps it around only for as long as the unit doesn't go to a persistently
failed state.
This is especially useful in combination with LUO, where we don't want to
keep around LUO sessions created by units that then proceeded to crash and
burn, and might be in a bad state afterwards.
Then, this deprecates
- BindToInterface=
- RelayTarget=
- RelayAgentCircuitId=
- RelayAgentRemoteId=
settings in [DHCPServer] section.
These are gracefully translated as new settings.
This has little to do with host configuration (where it was so far), and
a lot with what being executed, let's move it over.
Note that --help and man page so far differed here quite a bit: the
former had the "Execution" section, the latter didn't. This creates it
in the man page, to bring the two back in sync.
While commit 83c1e8ff5f added support for interactive polkit
authentication in `updatectl`, some users might want to disable that for
some use cases; so add the standard `--no-ask-password` argument.

Add --confidential-computing=sev-snp to run the guest as an AMD SEV-SNP
confidential VM. Loads a raw OVMF firmware blob via -bios (SNP doesn't
support the pflash + NVRAM split), attaches a sev-snp-guest object,
and hashes the kernel, initrd and cmdline into the launch measurement
when direct kernel boot is used. Incompatible features (Secure Boot,
CXL, virtio-balloon, SMBIOS credentials) are rejected or disabled; an
attached vTPM must be treated as untrusted by the guest.

Some drivers (currently mlx5_core) expose sub-functions (SFs) of a PCI
Physical or Virtual Function as auxiliary devices that carry a stable
`sfnum` sysfs attribute (the user-defined SF number passed to `devlink
port add ... sfnum N`). Their leaf devices (net, infiniband, ...)
currently inherit the parent PF/VF's `ID_PATH` and the SF netdev falls
through to the kernel-assigned `eth<N>` name.
Two patches:
1. `udev-builtin-path_id`: prepend an `sf-<N>` token when the walk
crosses an aux device with `sfnum`, so SF leaf devices get an `ID_PATH`
distinct from the parent PF/VF (e.g. `pci-0000:c1:00.0-sf-88`). Aux
devices without `sfnum` keep the pre-patch behaviour, so existing
`ID_PATH` values are unchanged and the patch needs no naming-scheme gate
(path_id is unversioned).
2. `udev-builtin-net_id`: name SF host netdevs analogously to SR-IOV VF
host netdevs — walk to the parent PCI function and append a
single-character `S<sfnum>` suffix. SFs hosted on SR-IOV VFs (VF-SF) get
both suffixes chained on the PF's base name (`enp193s0f0v0S88`). Gated
behind `NAMING_SUBFUNC` / `NAMING_V261`. Man page
(`systemd.net-naming-scheme(7)`) updated.
The patches apply to any driver that exposes its SF leaf devices below
an aux device exposing `sfnum`.
Validated on mlx5 hardware: PF, VF, SF-on-PF (`enp8s0f0S88`,
`pci-0000:08:00.0-sf-88`). VF-SF case verified with a fake-sysfs setup
since this is not supported by any real device and is more a theoretical
use case.
Add COREDUMP_CODE to the fields captured by systemd-coredump. This makes
it possible for system administrators to filter coredumps based on si_code,
which describes the reason why a given signal was sent.
For example, to find processes killed due to invalid permissions
(SEGV_ACCERR):
$ journalctl COREDUMP_SIGNAL=11 COREDUMP_CODE=2

Allow users to allow DHCPv6 unreachable/blackhole routes (installed
for delegated prefixes) into a specific routing table, analogous to
the existing RouteTable= in [DHCPv4] and [IPv6AcceptRA].
The config parser config_parse_dhcp_or_ra_route_table() is extended
with an AF_UNSPEC ltype discriminator for DHCPv6 (AF_INET6 is already
taken by NDISC/RA). link_get_dhcp6_route_table() follows the same
pattern as link_get_dhcp4_route_table() and link_get_ndisc_route_table(),
falling back to the VRF table when not explicitly set.
In dhcp_request_unreachable_route(), the table is applied only for
NETWORK_CONFIG_SOURCE_DHCP6 routes (the uplink unreachable aggregates),
not DHCP_PD routes (per-subnet routes on downstream interfaces), matching
the intent of the feature. The !route->table_set guard avoids overriding
a table already set by the route code.
Some drivers (currently mlx5_core) expose sub-functions (SFs) of a PCI
Physical Function as auxiliary devices. Each SF carries a host network
interface that sits below the aux device in sysfs:
/sys/devices/.../<PF BDF>/mlx5_core.sf.<idx>/net/eth<N>
Because the network device's immediate parent is the aux device and not
a PCI device, names_pci() bails out and these interfaces fall through
to the kernel-assigned eth<N> name, which is not stable across reboots,
module reloads or topology changes.
The naming applies when the SF network device's direct sysfs parent is
the aux device that exposes sfnum, i.e. the kernel driver passes the
aux device to SET_NETDEV_DEV(). mlx5_core does so. ice's
ice_sf_cfg_netdev() currently passes the parent PF's PCI device, so ice
SF network devices sit as siblings of the PF rather than below the aux
device and fall outside this precondition; pending a kernel change in
ice to mirror mlx5's SET_NETDEV_DEV(netdev, &adev->dev), they continue
to receive the kernel-assigned name as they do today.
The aux device exposes 'sfnum', the user-defined sub-function number
(the value passed to "devlink port add ... sfnum N"), which is stable
and unique within its parent PF. The aux device's direct sysfs parent
is the PF's PCI device.
Treat an SF host network device analogously to an SR-IOV VF host
network device: walk to the parent PCI function, derive the base name
from there, then append a single-character "S<sfnum>" suffix. Lowercase
's' is already taken (slot) and the existing grammar uses one character
per token, so 'S' is the best option.
E.g. for an SF whose parent PF is at PCI 0000:c1:00.0 and which was
added with "sfnum 88":
ID_NET_NAME_PATH=enp193s0f0S88
ID_NET_NAME_SLOT=enp193s0f0S88
This is parallel to how SR-IOV VFs get a "v<N>" suffix on top of the
parent PF's name.
Gate the new behaviour behind NAMING_SUBFUNC and NAMING_V261. Document
the new suffix in both the ID_NET_NAME_SLOT and ID_NET_NAME_PATH
grammars in systemd.net-naming-scheme(7) and add a v261 history entry.

Introduce COREDUMP_CODE as a new captured field alongside the existing

The default remains 4096 entries. Setting this to 0 disables caching
(similar to Cache=no).
CacheSize= is only read when Cache=yes or Cache=no-negative. When
Cache=no, caching is fully disabled regardless of CacheSize=.
Changes:
- Add cache_size field to Manager struct
- Parse CacheSize= from resolved.conf via gperf
- Thread cache_size through dns_cache_put() and helper functions
- Replace hard-coded CACHE_MAX with the configurable cache_size
- When cache_size is 0 or Cache=no, flush cache and skip caching
- Add man page documentation for the new option
- Add unit tests for cache size enforcement

When there is a NOTIFY_SOCKET, and FDs are received from the
payload following the FD Store protocol, forward them up the
chain to the service manager that is managing nspawn.
This allows FD Store persistence across container restarts,
and can chain up for user managers as well to survive restarting
those, or reexecs, and in the future reboots too via LUO.
Add a new test case to exercise the PID1 -> user session -> nspawn -> payload
chain.
In order to allow FD Stores of user units to survive a user
session restart, propagate FDs received via the protocol up one
level from user to system manager via sd_notify.
And the other way around, propagate them down via LISTEN_FDS
tagging them with the unit name so that the child manager can
inject them in the appropriate unit.
Ensure units that are dead or not loaded can get FDs added to
their stores, and that they are correctly propagated once the
unit is started or loaded. When the unit is not loaded we don't
know what the FD max limit is, so simply increase it for each FD
injected, and then when the unit is realised prune it down to
match the unit's now available config in case the limit is lower
than the number of FDs in the store.
Each FD sent up or down is assigned a monotonic index, and the manager
also sends a JSON map that associates the index with the original
unit and FDNAME:
{
"unit-name.service": [
{ "name": "fdname1", "index": 1 },
{ "name": "fdname2", "index": 2 }
],
...
}
This allows the manager to assign back the FDs to the appropriate
unit using the appropriate name, given the FDNAMEs are not unique.
When the kernel hands the command line to PID 1, any KEY=VALUE assignment
whose KEY does not contain a '.' is exported as an environment variable
(with '-' replaced by '_') rather than passed as an argument. Mimic the
same split in --boot mode so kernel-cmdline-style arguments passed after
the container path behave as they would on a real boot.
Add support for configuring cpuset partition type via the

without interference from other processes.
When set, systemd will write the partition type to the
cpuset.cpus.partition cgroup file. If the kernel rejects the value
(e.g., due to partition hierarchy rules), a warning is logged and the
unit continues with the kernel's default partition type.

The fix for the corrupted state when units become aliased on reload
leaks the now-aliased unit's resources, which become untracked and
essentially lost.
While fixing the state corruption is of course necessary, leaking
processes/etc. is not ideal for a system and service manager, so
instead attempt to keep track of them by creating stub units
on-the-fly.
This way resources are not leaked, there are clear indications of
where they moved, and all state can be tracked as expected.
This series adds a new `RestrictFileSystemAccess=` setting in the
`[Manager]` section of `system.conf` that enforces a deny-default
execution policy: only binaries residing on signed dm-verity block
devices (and the initramfs during early boot) are permitted to execute.
Everything else — tmpfs, procfs, sysfs, anonymous executable mappings,
unsigned dm-verity devices — is denied.
The directive takes the values `no` (default), `exec` (lock down
execution), and accepts `yes` as an alias for `exec`. The name is
deliberately broader than what the initial values cover so the same
setting can grow to restrict other filesystem access categories in the
future (e.g. `any` to deny all access from untrusted filesystems, not
just execution).
### How it works
The BPF program is entirely self-contained; PID1 loads it and the kernel
does the rest. When dm-verity brings up a device, the kernel calls
`security_bdev_setintegrity()` twice during `verity_preresume()`: once
with the root hash and once with the signature validity status. Our
`lsm/bdev_setintegrity` hook captures the second call and records the
device number in a BPF hash map if the signature is valid. When a device
is torn down, `lsm/bdev_free_security` cleans up the map entry. No
userspace map population is needed at any point.
The enforcement side hooks `bprm_check_security` (execve), `mmap_file`
(PROT_EXEC mappings including shared libraries), and `file_mprotect`
(W→X transitions like JIT and libffi). Each hook resolves the file's
backing device via `file->f_inode->i_sb->s_dev` and looks it up in the
verity device map. For block-backed filesystems, `s_dev` equals
`s_bdev->bd_dev`, which avoids an extra pointer chase and NULL check on
`s_bdev` — non-block filesystems simply miss in the map and get denied
by the default policy.
During early boot the initramfs needs to be trusted as well, since it
runs before any dm-verity volume is mounted. PID1 writes the initramfs
superblock's device number into a BPF global before attaching the
programs, and clears it after `switch_root` to close the trust window.
As a prerequisite, PID1 also verifies that
`dm_verity.require_signatures=1` is active — without it, unsigned
dm-verity devices could be created, which would weaken the security
model even though the BPF program would correctly deny execution from
them.
### Surviving daemon-reexec
The BPF programs and their verity device map must survive PID1
re-execution (daemon-reexec, switch_root, soft-reboot). Without
preservation, `manager_free()` would destroy the skeleton, the link FDs
would close, programs would detach, and the map would be freed. After
exec, a fresh skeleton would have an empty map — but existing dm-verity
devices have already signaled their integrity and won't do so again. A
deny-default policy plus an empty map means all execution denied and the
system is bricked.
We solve this by serializing the raw BPF link FDs and the `.bss` map FD
across exec using systemd's existing `serialize_fd` / `fdset_cloexec` /
`deserialize_fd` infrastructure. The kernel reference chain (link FD →
`struct bpf_link` → `struct bpf_prog` → `struct bpf_map`) keeps programs
attached and map data intact as long as the dup'd FDs survive. After
exec, PID1 detects the deserialized FDs and skips skeleton re-creation
entirely. If switching root, it uses the deserialized `.bss` map FD to
clear `initramfs_s_dev` via a targeted `mmap()` write, preserving the
other guard globals in `.bss`.
We intentionally avoid bpffs pinning. Pinned objects are discoverable
and manipulable by any process with sufficient privileges
(`BPF_OBJ_GET`, unlink). FD serialization keeps everything private to
PID1 with no external attack surface.
### Self-protection
BPF LSM programs attached via the tracing trampoline (`BPF_LSM_MAC`) are
inherently tamper-resistant — `bpf_tracing_link_lops` has no
`.update_prog` and no `.detach` callbacks, so the kernel rejects
`BPF_LINK_UPDATE` with `-EINVAL` and `BPF_LINK_DETACH` with
`-EOPNOTSUPP`. Once attached, our programs cannot be modified or
detached through the `bpf()` syscall.
The remaining attack vector is map injection: `BPF_MAP_GET_FD_BY_ID` to
obtain an FD to `verity_devices`, then `BPF_MAP_UPDATE_ELEM` to insert a
fake trusted device. The self-protection guard blocks this with three
hooks. `lsm/bpf_map` fires inside `bpf_map_new_fd()`, the chokepoint for
all code paths that produce a map FD, and denies access to our map IDs
from any process other than PID1 (identified via `tgid == 1`, which is
unspoofable — `bpf_get_current_pid_tgid()` reads `current->tgid` from
`pid->numbers[0].nr`, the init-namespace PID). `lsm/bpf_prog` provides
analogous protection for program FDs as defense-in-depth. `lsm/bpf`
handles `BPF_LINK_GET_FD_BY_ID` at the command level since there is no
`security_bpf_link()` hook in the kernel.
The guard starts inactive — all protected IDs default to 0 in `.bss`,
and no real BPF object has ID 0 — so there is no window where it
interferes with PID1's own setup. After attaching all programs, PID1
queries the kernel-assigned IDs via `bpf_obj_get_info_by_fd()` and
writes them into the guard's globals. From that point on, the guard is
active. The guard has zero collateral damage: it only denies access to
our specific object IDs, leaving bpftrace, bpftool,
`RestrictFileSystems=`, and all other BPF usage completely unaffected.
Additionally, a ptrace guard (`lsm/ptrace_access_check`) blocks
`PTRACE_MODE_ATTACH` to PID1 from other processes, preventing extraction
of sensitive state from PID1's address space via ptrace, `/proc/1/mem`,
`process_vm_readv()`, or `pidfd_getfd()`. `PTRACE_MODE_READ` is allowed
so that monitoring tools and `systemctl` continue to work normally.
### Limitations
- The enforcement hooks resolve trust by looking at
`file->f_inode->i_sb->s_dev` — the device number of the superblock that
owns the file's inode. This works correctly for files directly on a
dm-verity block device, but it does not see through overlayfs. When a
file is accessed on an overlay mount, `f_inode` points to the overlay
inode, and `i_sb->s_dev` is the overlay superblock's anonymous device
number — not the underlying dm-verity device. The overlay superblock has
no backing block device, so the lookup misses in the verity map and
execution is denied by the default policy.
This means that overlayfs mounts whose lower layers are on
dm-verity-protected volumes will currently have execution blocked, even
though the actual data is integrity-protected. The correct fix requires
a kernel extension that allows the BPF program to call something like
`d_real_inode()` to resolve through the overlay to the real inode on the
underlying filesystem, and then check that inode's superblock device
number against the verity map. I plan to add a BPF kfunc exposing this
functionality in a follow-up kernel series.
- Multi-device filesystems such as btrfs use entirely synthetic device
numbers and there is no way to reach the actual device backing the inode
from the inode itself. So `RestrictFileSystemAccess=` only works
reliably with a subset of filesystems. In practice this isn't a problem
because the feature is tailored to erofs; using it on arbitrary
filesystems requires careful vetting of the actual filesystem behaviour.
- The initial implementation also blocks JIT-style execution that relies
on memory mapped executable. This is part of `exec` semantics today and
can be loosened later by introducing finer-grained values (a common
pattern in systemd — following the precedent of `ProtectSystem=`, which
started as a boolean and later grew `auto`/`yes`/`full`/`strict`
semantics).
- The configuration is a system-wide setting with no per-unit opt-out.
This is intentional for the initial implementation: a global invariant
is easier to reason about and harder to accidentally weaken. Per-unit
relaxation can be added later if a concrete need arises.
### Testing
The series includes unit tests and integration tests covering both the
core enforcement logic and the self-protection guard. The unit test
loads the skeleton, attaches programs, populates guard globals, and
verifies that protected IDs are set correctly. The integration tests
exercise the guard by attempting `BPF_MAP_GET_FD_BY_ID` and
`BPF_PROG_GET_FD_BY_ID` from a non-PID1 process and verifying that
access is denied.
What we cannot currently test end-to-end is actual execution enforcement
against a dm-verity-signed root filesystem. The systemd test suite does
not yet have infrastructure for booting a VM with a signed dm-verity
rootfs image — the existing mkosi-based test framework lacks the ability
to produce and boot such images. This will hopefully change soon when
Daan integrates barrage into the test suite.

Add a new RestrictFileSystemAccess= boolean setting in the [Manager] section of
system.conf that enforces execution only from signed dm-verity block
devices and the initramfs during early boot.
When RestrictFileSystemAccess=yes is set, PID1 loads a BPF LSM program early in boot
that:
Integrity tracking (self-populating, no userspace involvement):
- bdev_setintegrity: records dm-verity signature status in a BPF hash
map when the kernel signals device integrity via
security_bdev_setintegrity()
- bdev_free_security: removes devices from the map on teardown
Execution enforcement (deny-default policy):
- bprm_check_security: blocks execve() from untrusted sources
- mmap_file: blocks PROT_EXEC mmap (shared libs, anonymous exec memory)
- file_mprotect: blocks W->X transitions (JIT, libffi, etc.)
Trust anchors:
- Signed dm-verity volumes (sig_valid flag in the BPF map)
- Initramfs (s_dev captured at load time, cleared after switch_root)
- Everything else is denied (tmpfs, procfs, sysfs, anonymous PROT_EXEC)
PID1 requires dm-verity require_signatures=1 to be enabled and refuses
to load the BPF program otherwise, ensuring the kernel enforces that all
dm-verity devices carry valid signatures.
After attach, PID1 extracts owned FDs from the skeleton (link FDs +
.bss map FD) and lets the skeleton be destroyed. The dup'd link FDs
keep programs attached via the kernel reference chain (link FD ->
bpf_link -> bpf_prog -> bpf_map). Destroying the skeleton unmaps the
.bss page from PID1's address space so no BPF state is readable via
/proc/1/mem. The .bss map FD is retained for targeted writes (clearing
initramfs_s_dev after switch_root via mmap).

BlockDeviceReplace=/mntpnt will move the btrfs filesystem from mount point to
the partition created. After moving, it will resize to take the whole
partition.
This is useful for OS installers that move a live system into a disk and
do not require a reboot.
UEFI firmware can report the currently-active keyboard layout via
EFI_HII_DATABASE_PROTOCOL.GetKeyboardLayout(). The layout descriptor
includes an RFC 4646 / BCP 47 language tag (e.g. "en-US"). Query this
from sd-boot/sd-stub and write it to a new LoaderKeyboardLayout EFI
variable, advertised through a new EFI_LOADER_FEATURE_KEYBOARD_LAYOUT
feature bit.
On the OS side, systemd-vconsole-setup reads the variable as a
lowest-priority fallback for the console keymap. To map the BCP 47
tag to a vconsole keymap we extend /usr/share/systemd/kbd-model-map
with an optional sixth column listing the comma-separated BCP 47 tags
each row covers; a new find_vconsole_keymap_for_bcp47() helper walks
the file, preferring an exact tag match and otherwise falling back to
the row whose tag matches the input's primary subtag. Credentials,
/etc/vconsole.conf, and vconsole.keymap= on the kernel command line
continue to take precedence.
bootctl status surfaces the new variable, printing the language tag
or "n/a (not reported by firmware)" when sd-boot advertises the
feature but the firmware HII database didn't expose a layout (common
on QEMU without a USB keyboard, since EDK2's PS/2 driver does not
register an HII keyboard layout).
The more(1) pager (part of util-linux) now supports secure mode,
which can be enabled with the MORESECURE environment variable.
Adding support for more(1) in secure mode serves as an alternative
for systems that do not have less installed or for users who prefer
it.
Commit d2fce960f9cac740 introduced secure mode in more(1) and the
new feature is available in version 2.42 of util-linux.
