Yu Watanabe 511d96d3b7 sd-dhcp-client: use unaligned_be32_sec_to_usec() 
Note, previously, we set 1 second if the time value is zero.
But the adjustment is dropped now, as for the lifetime we have explicit
check that the message has non-zero lifetime, and for T1 and T2 we have
better adjustment in client_set_lease_timeouts().

Yu Watanabe 9132cbd5ad sd-dhcp6-client: use be32_sec_to_usec() at more places 2023-09-21 03:59:00 +09:00
Yu Watanabe d8ec95c7ff sd-dhcp6-client: rework IA_NA or IA_PD getters 
This splits sd_dhcp6_lease_get_address() into small pieces,
and introduce FOREACH_DHCP6_ADDRESS() macro.
Also, the lifetimes provided by _get_address_lifetime() are now in usec,
and _get_address_lifetime_timestamp() provides timestamp.

The same change is also applied for IA_PD.

Zbigniew Jędrzejewski-Szmek f31fa08057 sd-network: modernize log error messages 
SYNTHETIC_ERRNO() is used where appropriate.

Splits in message format strings are removed, so that it's easier to
read/grep/copy them.

Yu Watanabe a93538e892 dhcp: introduce sd_dhcp_lease_get_timestamp() 
And drop sd_dhcp_client_get_lease_timestamp().

Also, this introduce sd_dhcp_lease_get_lifetime_timestamp() and friends,
which provides timestamp of the lifetime and so on, while
sd_dhcp_lease_get_lifetime() provides timestamp.

Yu Watanabe 5121163832 icmp6-util: several cleanups for icmp6_receive() 
- Rename the argument for storing the sender address,
- allow to call it with NULL for ret_xyz,
- reduce needless copy of timestamp when the message does not have
  timestamp.

Yu Watanabe 3b981f7428 Revert "test-dhcp-client: add temporary workaround for assertion failure" 
This reverts commit 1686c884bf.

The issue should be fixed by the previous commit. Let's drop the
workaround.

Yu Watanabe 5e2a89d84b sd-dhcp-client: ensure IAID and DUID being set on start 
After b2851e8d62, if IAID and DUID are not
set on start, calling sd_dhcp_client_set_iaid_duid_en() in
client_message_init() triggers assertion, as the client is already
running at the stage. Let's set IAID and DUID earlier.

Fixes #28990.

Luca Boccassi 1686c884bf test-dhcp-client: add temporary workaround for assertion failure 
Workaround for https://github.com/systemd/systemd/issues/28990

Introduced by https://github.com/systemd/systemd/pull/28932 but CI was
green there. Add a workaround to get the CI back in shape while it is
being investigated.
 2023-08-28 12:29:10 +01:00
Yu Watanabe b2851e8d62 sd-dhcp-client: make client initially in stopped state 
Previously, DHCP_STATE_STOPPED and DHCP_STATE_INIT are both handled as
not-running. Moreover, previously after sd_dhcp_client_start() is
called, the client still in INIT state (and thus handled as not-running)
even if its internal timer event sources are initialized.

Let's make only STOPPED state handled as not-running, and make the
client initially in STOPPED state.

Prompted by #28896.

Lennart Poettering 24ae45cb65 alloc-util: add free_many() helper 
We often free an array of things. Let's create a common helper for this,
and port some potential users over. (Not all, too lazy for that for
now).

Yu Watanabe 6ed69be98a Revert "network: DHCP6 client- Allow to send manual DUID" 
This reverts commits 89e73ce86f and
543d2a4d45.

The commit assign "custom" to fixed DUID type 5. When making DUID fully
configurable, the type number should be also configurable. Also, the
fully custom DUID should be acceptable for DHCPv4.

Introduced new field DHCPv6lease where these options are
added. This will be added to the JSON output when we query
org.freedesktop.network1.Manager object.

Lennart Poettering cf1ab844a9 tree-wide: drop "static inline" use in .c files 
"static inline" makes sense in .h files. But in .c files it's useless
decoration, the compiler should just make its own decisions there, and
it can do that.

hence, replace all remaining uses of "static line" by a simple" static"
in all .c files (but keep them in .h files, where they make sense)
