Lennart Poettering 23b1e8d087 units: we need systemd-journald.service from systemd-journal-flush.service 
This is a follow-up for d5ee050ffc, and
reintroduces a requirement dep from systemd-journal-flush.service onto
systemd-journald.service, but a weaker one than originally: a Wants= one
instead of a Requires= one.

Why? Simply because the service issues an IPC call to the journald,
hence it should pull it in. (Note that socket activation doesn't happen
for the Varlink socket it uses, hence we should pull in the service
itself.)

Lennart Poettering 007e03b284 util: another set of CVE-2021-4034 assert()s 
It's a good idea that we validate argc/argv when we are supposed to

Lennart Poettering 1462d2451a efi: use assert_se() instead of assert() to guard for OOM issues in EFI code 2022-02-01 15:31:20 +01:00
Lennart Poettering 8890ec82f5 macro: add ASSERT_SE_PTR() macro 
ASSERT_SE_PTR() is like ASSERT_PTR() but uses assert_se() instead of
assert() internally.

Code should use ASSERT_SE_PTR() where the check should never be
optimized away, even if NDEBUG is set.

Rationale: assert() is the right choice for validating assumptions about
our own code, i.e. checking conditions that are "impossible" to not
hold, because we ourselves hacked things up the "right" way of course.
assert_se() is the right choice for tests that come with a weaker
guarantee, they encode assumptions over other's API behaviour, i.e.
whether something can fail there or not.

When developing tools that are not oom-safe assert_se() is the right
choice: we know that on Linux OOM doesn't really happen, even though
theoretically the API allows it to happen.

Usecase for ASSERT_SE_PTR() is mostly the fatal memory allocation logic
for EFI memory allocations. So far it used regular assert() i.e. OOM
failurs would be totally ignored if NDEBUG is set. We'd rather have our
EFI program to print an assert message and freeze instead though.

Since kernel 5.17-rc1, 5.16.3, and 5.15.17 (more specifically,
https://github.com/torvalds/linux/commit/8dce43919566f06e865f7e8949f5c10d8c2493f5)
the kernel refuses to create an xfrm interface with zero ID.

Yu Watanabe 7b86854307 sd-dhcp-lease: fix reading unaligned memory 
The destination address was read twice, one is for prefixlen, and
other is for destination address itself. And for prefixlen, the address
might be read from unaligned buffer.

This also modernizes the code.

Yu Watanabe 8a7d048d1d sd-dhcp-server: set DHCPLease::server before hashmap_put() 
Otherwise, if the second push is failed, then the first hashmap contains
dirty entry.

Also, this makes hashmap_remove_value() used when removing leases to
make not wrong lease is removed from the hashmap.

Note, this just hide the root cause of the issue #22253, which will be
fixed in later commit.

Fixes #22253.
