- Update to 2.75, announce message:
Fix reversion on 2.74 which caused 100% CPU use when a
dhcp-script is configured. Thanks to Adrian Davey for
reporting the bug and testing the fix.
- Update to 2.74, announce message:
Fix reversion in 2.73 where --conf-file would attempt to
read the default file, rather than no file.
Fix inotify code to handle dangling symlinks better and
not SEGV in some circumstances.
DNSSEC fix. In the case of a signed CNAME generated by a
wildcard which pointed to an unsigned domain, the wrong
status would be logged, and some necessary checks omitted.
- Update to 2.73, announce message:
Fix crash at startup when an empty suffix is supplied to
--conf-dir, also trivial memory leak. Thanks to
Tomas Hozza for spotting this.
Remove floor of 4096 on advertised EDNS0 packet size when
DNSSEC in use, the original rationale for this has long gone.
Thanks to Anders Kaseorg for spotting this.
Use inotify for checking on updates to /etc/resolv.conf and
friends under Linux. This fixes race conditions when the files are
updated rapidly and saves CPU by noy polling. To build
a binary that runs on old Linux kernels without inotify,
use make COPTS=-DNO_INOTIFY
Fix breakage of --domain=<domain>,<subnet>,local - only reverse
queries were intercepted. THis appears to have been broken
since 2.69. Thanks to Josh Stone for finding the bug.
Eliminate IPv6 privacy addresses and deprecated addresses from
the answers given by --interface-name. Note that reverse queries
(ie looking for names, given addresses) are not affected.
Thanks to Michael Gorbach for the suggestion.
Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
for the bug report.
Add --ignore-address option. Ignore replies to A-record
queries which include the specified address. No error is
generated, dnsmasq simply continues to listen for another
reply. This is useful to defeat blocking strategies which
rely on quickly supplying a forged answer to a DNS
request for certain domains, before the correct answer can
arrive. Thanks to Glen Huang for the patch.
Revisit the part of DNSSEC validation which determines if an
unsigned answer is legit, or is in some part of the DNS
tree which should be signed. Dnsmasq now works from the
DNS root downward looking for the limit of signed
delegations, rather than working bottom up. This is
both more correct, and less likely to trip over broken
nameservers in the unsigned parts of the DNS tree
which don't respond well to DNSSEC queries.
Add --log-queries=extra option, which makes logs easier
to search automatically.
Add --min-cache-ttl option. I've resisted this for a long
time, on the grounds that disbelieving TTLs is never a
good idea, but I've been persuaded that there are
sometimes reasons to do it. (Step forward, GFW).
To avoid misuse, there's a hard limit on the TTL
floor of one hour. Thansk to RinSatsuki for the patch.
Cope with multiple interfaces with the same link-local
address. (IPv6 addresses are scoped, so this is allowed.)
Thanks to Cory Benfield for help with this.
Add --dhcp-hostsdir. This allows addition of new host
configurations to a running dnsmasq instance much more
cheaply than having dnsmasq re-read all its existing
configuration each time.
Don't reply to DHCPv6 SOLICIT messages if we're not
configured to do stateful DHCPv6. Thanks to Win King Wan
for the patch.
Fix broken DNSSEC validation of ECDSA signatures.
Add --dnssec-timestamp option, which provides an automatic
way to detect when the system time becomes valid after
boot on systems without an RTC, whilst allowing DNS
queries before the clock is valid so that NTP can run.
Thanks to Kevin Darbyshire-Bryant for developing this idea.
Add --tftp-no-fail option. Thanks to Stefan Tomanek for
the patch.
Fix crash caused by looking up servers.bind, CHAOS text
record, when more than about five --servers= lines are
in the dnsmasq config. This causes memory corruption
which causes a crash later. Thanks to Matt Coddington for
sterling work chasing this down.
Fix crash on receipt of certain malformed DNS requests.
Thanks to Nick Sampanis for spotting the problem.
Note that this is could allow the dnsmasq process's
memory to be read by an attacker under certain
circumstances, so it has a CVE, CVE-2015-3294
Fix crash in authoritative DNS code, if a .arpa zone
is declared as authoritative, and then a PTR query which
is not to be treated as authoritative arrived. Normally,
directly declaring .arpa zone as authoritative is not
done, so this crash wouldn't be seen. Instead the
relevant .arpa zone should be specified as a subnet
in the auth-zone declaration. Thanks to Johnny S. Lee
for the bugreport and initial patch.
Fix authoritative DNS code to correctly reply to NS
and SOA queries for .arpa zones for which we are
declared authoritative by means of a subnet in auth-zone.
Previously we provided correct answers to PTR queries
in such zones (including NS and SOA) but not direct
NS and SOA queries. Thanks to Johnny S. Lee for
pointing out the problem.
Fix logging of DHCPREPLY which should be suppressed
by quiet-dhcp6. Thanks to J. Pablo Abonia for
spotting the problem.
Try and handle net connections with broken fragmentation
that lose large UDP packets. If a server times out,
reduce the maximum UDP packet size field in the EDNS0
header to 1280 bytes. If it then answers, make that
change permanent.
Check IPv4-mapped IPv6 addresses when --stop-rebind
is active. Thanks to Jordan Milne for spotting this.
Allow DHCPv4 options T1 and T2 to be set using --dhcp-option.
Thanks to Kevin Benton for patches and work on this.
Fix code for DHCPCONFIRM DHCPv6 messages to confirm addresses
in the correct subnet, even of not in dynamic address
allocation range. Thanks to Steve Hirsch for spotting
the problem.
Add AddDhcpLease and DeleteDhcpLease DBus methods. Thanks
to Nicolas Cavallari for the patch.
Allow configuration of router advertisements without the
"on-link" bit set. Thanks to Neil Jerram for the patch.
Extend --bridge-interface to DHCPv6 and router
advertisements. Thanks to Neil Jerram for the patch.
