Yu Watanabe 6197db53ba sd-ndisc: make sd_ndisc return time values in usec 
This also introduces sd_ndisc_router_get_lifetime_timestamp() and
friends that return timestamp rather than timespan.

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.

Yu Watanabe fb70992d39 sd-dhcp6-client: introduce sd_dhcp6_lease_has_pd_prefix() and friend

These will be used in later commits.

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.
 2023-08-30 17:37:22 +09:00
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.

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.
