Yu Watanabe 117aa1cab4 journal/kmsg: drop Server.dev_kmsg_readable flag and use Server.read_kmsg 
When /dev/kmsg is opened, the two flags have the same value.

This also adds an assertion in server_read_dev_kmsg().

Yu Watanabe da741d9fd9 journal/kmsg: drop support old kernels (<3.5) without reading /dev/kmsg support 
/dev/kmsg is readable since kernel v3.5:
https://github.com/torvalds/linux/commit/e11fea92e13fb91c50bacca799a6131c81929986

Now our baseline on the kernel is v5.4. Let's assume /dev/kmsg is always
readable.

Yu Watanabe d50cfa98aa tree-wide: IFA_FLAGS is supported since kernel v3.14 
Now our baseline on the kernel is v5.4.
Let's unconditionally use the IFA_FLAGS attribute, and drop the getter
and setter for the deprecated header element.

Continuation of 29c2d4e158.

Yu Watanabe 6dbf2c1beb sd-netlink,sd-device: drop old kernels (<4.2) support 
NETLINK_LIST_MEMBERSHIPS is supported since kernel v4.2, specifically
https://github.com/torvalds/linux/commit/b42be38b2778eda2237fc759e55e3b698b05b315

Our baseline on the kernel is v5.4. Let's drop unnecessary conditions.

Yu Watanabe d3d375a686 udev-builtin-net_id: drop old kernels (<4.20) support 
Since kernel v4.20, specifically since
https://github.com/torvalds/linux/commit/9b8b2a323008aedd39a8debb861b825707f01420
IP-over-Infiniband driver also uses dev_port.

As our baseline on the kernel is v5.4. Let's remove the fallback code.
For more details about the fallback, see

Yu Watanabe 6d203bd830 test-condition: drop cgroup version check 
After f74ca66e68, we do not check the
cgroup version of the runtime environment, and unconditionally returns 0
for "v1", and 1 for "v2".

Now our baseline on the kernel is 5.4.

Note, the removed code triggered assert_return() in
sd_event_source_set_description().

Yu Watanabe d502816b3e unit-file: use set_free() to free paths

Yu Watanabe 5c6ea30209 core/unit: use string_hash_ops_free for Unit.aliases 2025-04-13 09:49:40 +09:00
Yu Watanabe 5793a39dd8 core,systemctl: unit_file_find_fragment() provides names with string_hash_ops_free 
names are assigned with set_put_strdup(), hence string_hash_ops_free is
used and we can use set_free() rather than set_free_free().
 2025-04-13 09:49:40 +09:00
Yu Watanabe c4c4ea2fb6 core: replace unnecessary use of set_free_free() with set_free() 
These variables are assigned with set_put_strv(), hence
string_hash_ops_free is used.

This also drops unnecessary call of set_ensure_allocated() with wrong
hash ops.

Yu Watanabe 94dd3a569c event-util: use DEFINE_HASH_OPS_WITH_VALUE_DESTRUCTOR() to define event_source_hash_ops 
Currently, the hash_ops is only used by set, so this does not change
anything. But, there are several benefits,
- we can drop cast in the definition,
- the hash_ops can be also used by hashmap.

Yu Watanabe f4a717aa4d socket-proxy: use hash_ops with destructor for managing Connection 
This also renames context_clear() -> context_done(), to follow our

Mike Yuan 7369c037e2 fstab/gpt-auto: hook up validatefs to /sysroot/usr/ rather than /sysusr/usr/ 
We carry a special logic for /usr/ in initrd that it initially gets
mounted to /sysusr/usr/ and later bind mounted to /sysroot/usr/.
When hooking up validatefs it is hence necessary to wait for
the bind mount and validate that, rather than the /sysusr/usr/
established as intermediate transport.

Alternative to #37102
