systemd-boot uses the existance of loader/keys/auto to determine
whether to auto-enroll secure boot or not so only create the directory
if we're actually going to put auto-enroll signature lists in it.
The second check was searching the symbols into the same array, but
using the size of the other. This generated a SIGSEV when they
occassionally mismatched.
lcov 2.1 introduced additional consistency checks [0] which make it trip
over our coverage results quite often:
Summary coverage rate:
source files: 915
lines.......: 36.9% (78950 of 214010 lines)
functions...: 53.3% (6906 of 12949 functions)
Message summary:
73 warning messages:

lcov: ERROR: (corrupt) unable to read trace file '/var/tmp/systemd-test-TEST-04-JOURNAL/coverage-info.new': lcov: ERROR: (inconsistent) "/build/src/shutdown/umount.c":298: function 'umount_with_timeout' is not hit but line 317 is.
To skip consistency checks, see the 'check_data_consistency' section in man lcovrc(5).
(use "lcov --ignore-errors inconsistent ..." to bypass this error)
(use "lcov --ignore-errors corrupt ..." to bypass this error)
This is caused by coverage collected during shutdown which is a bit
unreliable, especially towards the final shutdown stage(s). Let's just
ignore the consistency errors for now.

The proposal in https://github.com/systemd/systemd/pull/35091 suggests
that there are going to be more resources sooner or later that shall be
embeddable in a UKI, but are specific to some machine. The .hwids logic
as it is implemented right now is conceptually flexible enough to cover
that too (as long as the system has SMBIOS and thus CHIDs). Hence, let's
prepare the ground for a future (that might possibly never come, but
let's keep the door open) where the section can be reused for this
purpose.
The patch is really dumb ultimately. it just changes the initial field
in the "Device" struct to carry not just the size of it (as before) but
also a type indicator, that is for now fixed to 1, indicating DT blobs.
This breaks compatibility, hence this should get merged before we do the
v257 release, so that this is done properly before the first release
with .hwids.
We use the $WATCHDOG_USEC variable for two very closely uses: as part of
the sd_watchdog_enabled() protocol for implementing service watchdogs.
And as part of the protocol between the service manager and
systemd-shutdown across the PID 1 execve() transition during shutdown.
Apparently some exitrds tools got confused by the latter use. Let's
address that by setting $WATCHDOG_PID to 1, in accordance to the
sd_watchdog_enabled() protocol to make clear this is only intended for
PID 1 and nothing else.

Given how long it took to come to a conclusion of the discussions around
https://github.com/systemd/systemd/issues/35026, let's add a comment
that makes this easier to grok for the next time this comes up.

libnvme 1.11 appears to require a kernel built with NVME TLS
kconfigs, and fails hard if it is not, as the expected
privileged keyring '.nvme' is not present. We cannot just
create it from userspace, as privileged keyrings can only
be created by the kernel itself (those starting with '.').
Skip the test if the library exactly matches this version.

Fixes https://github.com/systemd/systemd/issues/35130
Stub behavior will be as following:
1. If there are no `.dtbauto` sections then is used `.dtb` if present
2. If there are `.dtbauto` sections and there is at least one matching
(either with the firmware-provided DT or via `.hwids`) then it'll be
used instead of the `.dtb`.
Based on #28959 and [dtbloader](https://github.com/TravMurav/dtbloader)
Closes#28959Fixes#31946
While doing that, even if mknod() failed, we anyway try to fall back to
use bind mount if arg_uid_shift == 0.
Mostly no functional change, just refactoring and preparation for later commit.

If nspawn is invoked with DevicePolicy= but DeviceAllow= does not
contain /dev/fuse, nspawn will fail to get fuse version with -EPERM.
Let's silence the warning in that case.
Outside of x86, some machines (e.g. Apple silicon, AMD Opteron A1100)
have physical memory mapped above 4GiB, meaning this allocation will
fail, causing the entire boot process to fail on these machines.
This commit makes it so that the below-4GB address space allocation
requirement is only set on x86 platforms, and not on other platforms
(that don't have the specific Linux x86 boot protocol), thereby fixing
boot on those that have no memory mapped below 4GiB in their address
space.
Tested on an Apple silicon M1 laptop and an AMD x86_64 desktop tower.
Fixes: #35026
Previously, when multiple routers send RAs with the same preference,
then the kernel merges routes with the same gateway address:
===
default proto ra metric 1024 expires 595sec pref medium
nexthop via fe80::200:10ff:fe10:1060 dev enp0s9 weight 1
nexthop via fe80::200:10ff:fe10:1061 dev enp0s9 weight 1
===
This causes IPv6 Conformance Test v6LC.2.2.11 failure, as reported in #33470.
To avoid the coalescing issue, we can use nexthop, as suggested by Ido Schimmel:
https://lore.kernel.org/netdev/ZytjEINNRmtpadr_@shredder/
> BTW, you can avoid the coalescing problem by using the nexthop API.
> # ip nexthop add id 1 via fe80::200:10ff:fe10:1060 dev enp0s9
> # ip -6 route add default nhid 1 expires 600 proto ra
> # ip nexthop add id 2 via fe80::200:10ff:fe10:1061 dev enp0s9
> # ip -6 route append default nhid 2 expires 600 proto ra
> # ip -6 route
> fe80::/64 dev enp0s9 proto kernel metric 256 pref medium
> default nhid 1 via fe80::200:10ff:fe10:1060 dev enp0s9 proto ra metric 1024 expires 563sec pref medium
> default nhid 2 via fe80::200:10ff:fe10:1061 dev enp0s9 proto ra metric 1024 expires 594sec pref medium
Fixes#33470.

By the previous commit, configuration source of addresses and routes are
saved on stop and restored on start. Hence, we can keep dynamic
configurations on stop.
Co-authored-by: Jian Zhang <zhangjian.3032@bytedance.com>
Currently, only configuration sources and providers of addresses and
routes are serialized/deserialized.
This should mostly not change behavior, as dynamic (except for DHCPv4)
configurations will be dropped before stopping networkd, and for DHCPv4
protocol, we have already had another logic to handle DHCPv4
configurations.
Preparation for later commits.

If a netdev is detached for some reasons, then previously the request
was simply cancelled, and the underlying interface never enter the
configured state, as the 'stacked_netdevs_created' flag never set.
This makes the counter decremented manually by the function, and set the
flag. So, the underlying interface can eter the configured state.
After PR #34909, networkd tries to update an existing netdev interface if
possible. But, when .netdev files are loaded on start, we have not
enumerate interfaces, so we do not know if the corresponding interface
exists or not. Let's delay processing request a bit.
Follow-up for PR #34909.
This fixes an issue that network interfaces cannot join a master netdev,
like bond or bridge, when the corresponding .netdev is reloaded.
With PR #34909, networkd supports reloading .netdev files. However,
When a .netdev file is modified and reloaded, ifindex is copied from
the old NetDev object to the new one. Thus, even if the interface is
successfully updated, netdev_set_ifindex_impl() will return 0 and
netdev_enter_ready() will never called. If the netdev is a kind of
master netdev, then port interfaces cannot join the master netdev,
as REQUEST_TYPE_SET_LINK_MASTER requires that the master netdev is
in the ready state.
Follow-up for 17c5337f7b2993619d84acc2088b2ba1789e6477.
Older kernels (older than v6.5) refuse RTM_NEWLINK messages with IFLA_ADDRESS
attribute when the netdev already exists and is running, even if the MAC
address is unchanged.
So, let's not set IFLA_ADDRESS or IFLA_MTU if they are unchanged, and
set the attributes only when we can update them.
