It's four months since the last release, and many small changes have
accumulated, mainly fixes, so I've released dnsmasq-2.40.
Available, as usual, from
Changelog from 2.39:
Make SIGUSR2 close-and-reopen the logfile when logging
direct to a file. Thanks to Carlos Carvalho for
suggesting this. When a logfile is created, change
its ownership to the user dnsmasq will run as, don't
leave it owned by root.
Set a special tag, "known" for hosts which are matched by
a dhcp-host or /etc/ethers line. This is especially
useful to be able to do --dhcp-ignore=#known, like ISCs
Explicitly set a umask before creating the leases file,
rather than relying on whatever we inherited. The
permissions are set to 644.
Fix handling of fully-qualified names in --dhcp-host
directives and in /etc/ethers. These are now rejected
if the domain doesn't match that given by --domain,
and used correctly otherwise. Before, putting
a FQDN here could cause the whole FQDN to be used as
hostname. Thanks to Michael Heimpold for the bug report.
Massive but trivial edit to make the "daemon" variable
global, instead of copying the same value around as the
first argument to half the functions in the program.
Updated Spanish manpage and message catalog. Thanks
to Chris Chatham.
Added patch for support of DNS LOC records in
contrib/dns-loc. Thanks to Lorenz Schori.
Fixed error in manpage: dhcp-ignore-name ->
dhcp-ignore-names. Thanks to Daniel Mentz for spotting
Use client-id as hash-seed for DHCP address allocation
with Firewire and Infiniband, as these don't supply an MAC
Tweaked TFTP file-open code to make it behave sensibly
when the filesystem changes under its feet.
Added DNSMASQ_TIME_REMAINING environment variable to the
Always send replies to DHCPINFORM requests to the source
of the request and not to the address in ciaddr. This
allows third-party queries.
Return "lease time remaining" in the reply to a DHCPINFORM
request if there exists a lease for the host sending the
Added --dhcp-hostsfile option. This gives a superset of
the functionality provided by /etc/ethers. Thanks to
Greg Kurtzer for the suggestion.
Accept keyword "server" as a synonym for "nameserver" in
resolv.conf. Thanks to Andrew Bartlett for the report.
Add --tftp-unique-root option. Suggestion from Dermot
Tweak TFTP retry timer to avoid problems with difficult
clients. Thanks to Dermot Bradley for assistance with
Continue to use unqualified hostnames provided by DHCP
clients, even if the domain part is illegal. (The domain
is ignored, and an error logged.) Previously in this
situation, the whole name whould have been
rejected. Thanks to Jima for the patch.
Handle EINTR returns from wait() correctly and reap
our children's children if necessary. This fixes
a problem with zombie-creation under *BSD when using
Escape spaces in hostnames when they are stored in the
leases file and passed to the lease-change
script. Suggestion from Ben Voigt.
Re-run the lease chamge script with an "old" event for
each lease when dnsmasq receives a SIGHUP.
Added more useful exit codes, including passing on a
non-zero exit code from the lease-script "init" call when
--leasefile-ro is set.
Log memory allocation failure whilst the daemon is
running. Allocation failures during startup are fatal,
but lack of memory whilst running is worked around.
This used to be silent, but now is logged.
Fixed misaligned memory access which caused problems on
Blackfin CPUs. Thanks to Alex Landau for the patch.
Don't include (useless) script-calling code when NO_FORK
is set. Since this tends to be used on very small uclinux
systems, it's worth-while to save some code-size.
Don't set REUSEADDR on TFTP listening socket. There's no
need to do so, and it creates confusing behaviour when
inetd is also listening on the same port. Thanks to Erik
Brown for spotting the problem.
