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".

Yu Watanabe cc983fc9dc resolve: drop code for supporting old kernels (<3.2) 
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 37edefb33f socket-proxy: use event_source_hash_ops for managing event sources 2025-04-13 04:28:35 +09:00
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
recent coding style.

Yu Watanabe 10e41cdddc socket-proxy: use event_reset_time_relative() 
Also, split out context_reset_timer() from connection_release().
No functional change. Preparation for later change.

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

Yu Watanabe 67bdb6bee0 network/netdev: remove support of netdevsim 
netdevsim device creation by networkd was deprecated by
59a9ef1022 (v246), and it does not work
since kernel v5.2:
https://github.com/torvalds/linux/commit/e05b2d141fef22cfac1928cf0eb6890e5dae4216

Now our baseline for the kernel is v5.4. Let's completely kill the
feature.

Yu Watanabe 012d76ab79 test: also wait for all queued events being processed

the device node may not exist any more when 'udevadm wait' command succeeds.
