Replace fixed 128-byte fields for search domains, static routes and domain name servers with variable sized uint8_t chunks. Allows larger lists of search domains and static routes while making common situations use much less memory. Original report of breaching the 128-byte limit for static routes from James Cook via misc@. Testing of various versions by Andreas Kusalananda.

Changes since 1.58: +24 -35 lines
Diff to previous 1.58 (colored)
Restructure code to simplifiy imsg communications, further separating DHCP knowledge and interface manipulation. Unprivileged process now sends proposal derived from the accepted lease to the privileged process rather than individual interface manipulation requests. The only intended functional change is that /etc/resolv.conf.tail is not re-read each time a new proposal is implemented, rather than once at dhclient startup.

Bring priv_write_resolv_conf() into line with other priv_ functions invoked from the dispatch loop. i.e. don't pass it the imsg, just pass a pointer to the data and a size after ensuring there is data to pass.

No need for passing messages to the priv process. Tweak lease file handling a bit in passing. Monitoring the -L file with external programs like sysutils/entr still works. Looks good to sthen@.

Since deleting all the addresses on an interface removes all the relevant entries from the arp cache, don't bother asking for/processing arp entries in the route dumps. Thus allowing use of NET_RT_FLAGS with RTF_GATEWAY and AF_INET, to ask for only the routes dhclient wants to expunge rather than all routes in existance. Greatly shrinks and simplifies the code.

Rework log messages to be more useful. Rename IMGS_CLEANUP/imsg_cleanup/cleanup to IMSG_HUP/imsg_hup/sendhup to more accurately reflect intent of causing the privileged process to initiate restart. There should now be one and only one message logged at termination or restart, logged by the process initiating the termination or restart. As part of fixing this, remove duplicate cleanup attempts and exit after sending IMSG_HUP. These make logged messages more consistant and fix issues with incorrect cleanups.

Refactor code a bit. Calculate resolv.conf contents once when binding a lease and reuse as required whenever resolv.conf is written. Use write_file() rather than a custom message/functions to write out resolv.conf.

Try harder to cleanup when exiting. In particular catch signals SIGHUP, SIGINT, SIGTERM, SIGUSR1, SIGUS2 and cleanup before exiting when getting them. Cleanup meaning removing routes and the interface address added. Tweaks and feedback from phessler@, sthen@, otto@, deraadt@

Use the libutil imsg framework rather than a hand-rolled local version. This is the last hand-rolled imsg implementation I could spot. Doesn't seem to break sparc64. Suggested by chris@, tweaks from brad@ and reyk@. ok reyk@

Nuke dhclient-script and dhclient.conf 'script' directive. Do all interface and route configuration via ioctl's and routing sockets. This will break configurations using local enhancements of dhclient-script, which will now require alternate arrangements. Committing early to allow time to identify and develop required alternatives. Several proddings by deraadt@.
