- -q is now the default behaviour on dhclient, with -d or -v enabling
non-quiet (stderr logging) mode. [ISC-Bugs #16872]
[ISC-Bugs #16881]
- DHCPv4 is now the default (as documented) rather than DHCPv6. The default
was set to DHCPv6 to facilitate ease early development, and forgotten.
[ISC-Bugs #16881]
- Corrected a segmentation violation in DHCPv4 socket processing.

initialized. [ISC-Bugs #16865]
- Silenced several other compiler warnings. [ISC-Bugs #16865]
- Include the more standard sys/uio.h rather than rely upon other header
files to include it (fixes a BSDI compile failure). [ISC-Bugs #16865]
determined from payload, because some NIC drivers return more data than
they actually recived; IP and UDP packets now stored in aligned data
structures; outgoing packet TTL increased from 16 to 128. [rt15583]
should send out option 81 (FQDN). Defaults to "on". If set to "off",
the FQDN option is not sent, even if the client requested it. This is
needed because some clients misbehave otherwise. [rt16624]
are now sorted according to the preference to re-allocate that lease to
returning clients. This should eliminate pool starvation problems
arising when "INIT" clients were given new leases rather than presently
active ones. [ISC-Bugs #16831]
which is used to retain relay agent option contents from when the
client was in INIT or REBIND states. This should solve problems where
relay agent options were not echoed from the server, even when giaddr
was set. [ISC-Bugs #16787]
was directly attached to the same broadcast domain as the DHCP server,
the RFC3046 relay agent information option was not being returned to the
relay in the server's replies. This was fixed; the dhcp server no longer
requires the giaddr to reply with relay agent information. Note that
this also improves compatibility with L2 devices that "intercept" DHCP
packets and expect relay agent information even in unicast (renewal)
replies. [ISC-Bugs #16762]
3.1.0a1's tables resulted in a reduction in default server memory use.
The new selected values provide more of a zero sum (increasing the size
of tables likely to be populated, decreasing the size of tables unlikely).
- Lease structures appear in three spearate hashes: by IP address, by UID,
and by hardware address. One type of table was used for all three, and
improvements to IP address hashing were applied to all three (so UID and
hardware addresses were treated like 4-byte integers). There are now two
types of tables, and the uid/hw hashes use functions more appropriate
to their needs.
- The max-lease-misbalance percentage no longer causes scheduled rebalance
runs to be skipped: it still governs the schedule, but every scheduled
run will attempt balance.
[ISC-Bugs #16396]
entering normal state. [ISC-Bugs #16412]
- UPDREQ/UPDREQALL handling was optimized - it no longer dequeues and
requeues all pending updates. This should reduce the number of spurious
'xid mismatch' log mesasges. [ISC-Bugs #16412]
