Subject: Announce: dnsmasq 2.33 - msg#00007

Changelog below: there's no pressing need to upgrade unless you want the
external lease database feature, or have a Cisco router.


Cheers,

Simon.


version 2.33
Remove bash-specific shellcode from the Makefile.

Fix breakage with some DHCP relay implementations which
was introduced in 2.28. Believing the source port in
DHCP requests and sending the reply there is sometimes a
bad thing to do, so I've reverted to always sending to
the relay on port 68. Thanks to Daniel Hamlin and Alex
(alde) for bug reports on this.

Moved the SuSe packaging files to contrib. I will no
longer attempt to maintain this in the source tarball. It
will be done externally, in the same way as packaging for
other distros. Suse packages are available from
ftp://ftp.suse.com/pub/people/ug/

Merged patch from Gentoo to honour $LDFLAGS environment.

Fix bug in resolv.conf processing when more than one file
is being checked.

Add --dns-forward-max option.

Warn if --resolv-file flags are ignored because of
--no-resolv. Thanks to Martin F Krafft for spotting this
one.

Add --leasefile-ro option which allows the use of an
external lease database. Many thanks to Steve Horbachuk
for assistance developing this feature.

Provide extra information to lease-change script via its
environment. If the host has a client-id, then
DNSMASQ_CLIENT_ID will be set. Either the lease length (in
DNSMASQ_LEASE_LENGTH) or lease expiry time (in
DNSMASQ_LEASE_EXPIRES) will be set, depending on the
HAVE_BROKEN_RTC compile-time option. This extra
information should make it possible to maintain the lease
database in external storage such as LDAP or a relational
database. Note that while leasefile-ro is set, the script
will be called with "old" events more often, since
changes to the client-id and lease length
(HAVE_BROKEN_RTC) or lease expiry time (otherwise)
are now flagged.

Add contrib/wrt/* which is an example implementation of an
external persistent lease database for *WRT distros with
the nvram command.

Add contrib/wrt/dhcp_release.c which is a small utility
which removes DHCP leases using DHCPRELEASE operation in
the DHCP protocol.
