Subject: sd-dhcp-client: don't fail hard if UDP socket can not be bound
X-Git-Tag: v215~124
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=fb41e6d7c68c83558f8482f7fc72794a67b0638f

sd-dhcp-client: don't fail hard if UDP socket can not be bound

Even if we cannot renew the lease at T1, we will likely succeed at T2, so warn and ignore the failure.

This could happen if for whatever reason the received address is not yet configured, or it has
been lost.
