Modify the DDNS handling code. In a previous patch we added logging
code to the DDNS handling. This code included a bug that caused it
to attempt to dereference a NULL pointer and eventually segfault.
While reviewing the code as we addressed this problem, we determined
that some of the updates to the lease structures would not work as
planned since the structures being updated were in the process of
being freed: these updates were removed. In addition we removed an
incorrect call to the DDNS removal function that could cause a failure
during the removal of DDNS information from the DNS server.
Thanks to Jasper Jongmans for reporting this issue.
([ISC-Bugs #27078], CVE: CVE-2011-4868, bnc#741239)
- Fixed close-on-exec patch to not set it on stderr (bnc#732910)
- Fixed incorrect "a" array type option parsing causing to discard
e.g. classless static routes from lease file [reported as ISC-Bug
27289] and zero-length option parsing such as dhcp6.rapid-commit
in dhclient6 [reported as ISC-Bug 27314] (bnc#739696).
- Fixed dhclient to include its pid number in syslog messages.
- Fixed to use P2 in the spec version, not in the release tag.

a DoS due to processing certain regular expressions (bnc#735610)
and several important DDNS related fixes:
* Add a check for a null pointer before calling the regexec function.
Without out this check we could, under some circumstances, pass
a null pointer to the regexec function causing it to segfault.
Thanks to a report from BlueCat Networks. [ISC-Bugs #26704]
CVE-2011-4539.
* Fix the code that checks for an existing DDNS transaction to
cancel when removing DDNS information, so that we will continue
with the processing if we have a lease even if it doesn't have an
outstanding transaction. [ISC-Bugs #24682]
* Add AM_MAINTAINER_MODE to configure.ac to avoid rebuilding
configuration files. [ISC-Bugs #24107]
* Add support for passing DDNS information to a DNS server over
an IPv6 address. [ISC-Bugs #22647]
* Enhanced patch for 23595 to handle IPv4 fixed addresses more
cleanly. [ISC-Bugs #23595]
- Refreshed ldap patch

(CVE-2011-2748,CVE-2011-2749,[ISC-Bugs #24960],bnc#712653), that
allowed remote attackers to cause a denial of service (a daemon
exit) via crafted BOOTP packets. Further also DNS update fix to
detect overlapping pools or misconfigured fixed-address entries,
that caused a server crash during DNS update and other fixes.
For a complete list, please see the RELNOTES file provided in
the package and also available online at http://www.isc.org/.
- Merged/adopted dhclient option-checks, send-hostname-rml, ldap
patch, xen-checksum, close-on-exec patches and removed obsolete
in6_pktinfo-prototype and relay-no-ip-on-interface patches.
- Moved server pid files into chroot directory even chroot is
not used and create a link in /var/run, so it can write one
when started as user without chroot and avoid stop problems
when the chroot sysconfig setting changed (bnc#712438).
- Disabled log-info level messages in dhclient(6) quiet mode to
avoid excessive logging of non-critical messages (bnc#711420).
- Fixed dhclient-script to not remove alias IP when it didn't
changed to not wipe out iptables connmark when renewing the
lease (bnc#700771). Thanks to James Carter for the patch.
- Fixed DDNS-howto.txt reference in the config file; it has been
moved to the dhcp-doc package (bnc#697279).
- Removed GPL licensed files (bind-*/contrib/dbus) from bind.tgz
to ensure, they're not used to build non-GPL dhcp (bnc#714004).
- Changed to apply strict-aliasing/RELRO for >= 12.x only

startup of the dhcp server in cases where the ldap server is not
yet started. Set the ldap-init-retry <num> option in dhcpd.conf
to enable it (bnc#627617). Merged in the actual ldap patch.
- Cleaned up init script error reporting, no -TERM for killproc.

dhclient pretty escape and string option checks. Use relaxed
domain-name option check causing a regression, when the server
is misusing it to provide a domain list and does not provide
it via the domain-search option; pretty escape semicolon as well
(bnc#675052, CVE-2011-0997).

handling of connection requests on the failover port.
Previously a connection request from a source that wasn't
listed as a failover peer would cause the server to become
non-responsive. ([ISC-Bugs #22679] CERT: VU#159528 CVE:
CVE-2010-3616, bnc#659059).

without any IPv4 address assigned (bnc#631305, reported upsteam
as [ISC-Bugs #22409]).
- Fixed a common infinite loop while parsing options with optional
parts in the value such as in slp-service-scope option (bnc#643845,
reported upsteam as [ISC-Bugs #22410]).
- Fixed init scripts to report correct LSB codes in status action,
when the config file or the binary do not exists (bnc#640336).
- Fixed syntax of a check in the rcdhcrelay[6] (bnc#648580)
- Avoid pid check error message in the rcdhcpd[6] (bnc#646875)

a pair of bug fixes including one for a security related bug
(bnc#612546, CVE-2010-2156):
* A bug was fixed that could cause the DHCPv6 server to
advertise/assign a previously allocated (active) lease to a
client that has changed subnets, despite being on different
shared networks. Dynamic prefixes specifically allocated in
shared networks also now are not offered if the client has
moved. [ISC-Bugs #21152]
* Accept a client id of length 0 while hashing. Previously the
server would exit if it attempted to hash a zero length client
id, providing attackers with a simple denial of service attack.
[ISC-Bugs #21253]

release, providing DHCPv6 client/server/relay implementation.
The programs act in DHCPv6 mode, when the -6 start option is set.
We install separate init scripts with a 6 at the end to handle
them, that is /etc/init.d/dhcpd6 and dhrelay6. Further, there is
also a link to the binaries with a 6 at the end, e.g. dhclient6,
making it visible, that the installed version supports DHCPv6.
- Moved additional documentation to a separate dhcp-doc package.
- Changed to provide config files and scripts as source files
instead of patches to the ISC scripts.
- Adopted spec file and config/scripts, merged in all patches.
- Implemented RFC 3442 classless static routes support in the
dhclient-script (bnc#555870).
OBS-URL: https://build.opensuse.org/package/show/network:dhcp/dhcp?expand=0&rev=15
to not to break the defaultroute/hostname setup (bnc#555095).
- Don't request any specific lease-time by default (bnc#516459).
- Fixed dhclient-script to forward new_domain_search as DNSSEARCH
to netconfig.
- Updated to dhcp-3.1.3 maintenance release fixing several issues
(a digest, see RELNOTES for the complete list):
* Remove infinite loop in token_print_indent_concat().
* A parser bug was fixed that segfaulted if site-option-space
was tried to be used interchangeably with vendor-option-space.
* Two uninitialized stack structures are now memset to zero,
thanks to patch from David Cantrell at Red Hat.
* Memory leak in the load_balance_mine() function is fixed. This
would leak ~20-30 octets per DHCPDISCOVER packet while failover
was in use and in normal state.
* Fixed setting hostname in Linux hosts that require hostname
argument to be double-quoted. Also allow server-provided
hostname to override hostnames 'localhost' and '(none)'.
* Added client support for setting interface MTU and metric,
thanks to Roy "UberLord" Marples <roy@marples.name>.
* Fixed failover reconnection retry code to continue to retry to
reconnect rather than restarting the listener.
* Fixed a bug where an OMAPI socket disconnection message would
not result in scheduling a failover reconnection, if the link
had not negotiated a failover connect yet (e.g.: connection
refused, asynch socket connect() timeouts).
* Versions 3.0.x syntax with multiple name->code option
definitions is now supported. Note that, similarly to 3.0.x,
for by-code lookups only the last option definition is used.
* Fixed a fenceposting bug when a client had two host records
configured, one using 'uid' and the other using 'hardware
ethernet'. CVE-2009-1892
- Updated to dhcp-3.1.3-ldap-patch-mt-01 including previous fixes.
- Merged dhclient script, removed obsolete CVE-2009-1892 fix.
