[installer 2230] ISC dhcp-4.0.2

ISC dhcp-4.0.2 出ています。

☆ ISC dhcp-4.0.2
http://www.isc.org/sw/dhcp
ftp://ftp.isc.org/isc/dhcp/dhcp-4.0.2.tar.gz

Changes since 4.0.2rc1

- None

Changes since 4.0.2b3

- When using 'ignore client-updates;', the FQDN returned to the client
is no longer truncated to one octet.

Changes since 4.0.2b2

- Fix test in dhcp_interface_signal_handler to check that the inner handler
has a signal_handler before calling it.

- ./configure now checks to ensure the intX_t and u_intX_t types are defined,
correcting a compilation failure when using Sun's compiler.

- Modified the handling of a connection to avoid releasing the omapi io
object for the connection while it is still in use. One symptom from
this error was a segfault when a failover secondary attempted to connect
to the failover primary if their clocks were not synchronized.

- Both host and subnet6 configuration groups are now included whether a
fixed-address6 (DHCPv6) is in use or not. Host scoped configuration takes
precedence. This fixes two bugs, one where host scoped configuration
would not be included from a non-fixed-address6 host record, and the equal
and opposite bug where subnet6 scoped configuration would not be used when
over-riding values were not present in a matching fixed-address6 host
configuration.

Changes since 4.0.2b1

- 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).

- A bug was fixed that caused the 'conflict-done' state to fail to be parsed
in failover state records.

! A stack overflow vulnerability was fixed in dhclient that could allow
remote attackers to execute arbitrary commands as root on the system,
or simply terminate the client, by providing an over-long subnet-mask
option. CERT VU#410676 - CVE-2009-0692

- 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 bug where a time difference of greater than 60 seconds between a
failover pair could cause the primary to crash on contact with the
secondary. Thanks to a patch from Steinar Haug.

- Don't look for IPv6 interfaces on Linux when running in DHCPv4 mode.
Thanks to patches from Matthew Newton and David Cantrell.

- Secondary servers in a failover pair will now perform ddns removals if
they had performed ddns updates on a lease that is expiring, or was
released through the primary. As part of the same fix, stale binding scopes
will now be removed if a change in identity of a lease's active client is
detected, rather than simply if a lease is noticed to have expired (which it
may have expired without a failover server noticing in some situations).

- A patch supplied by David Cantrell at RedHat was applied that detects
invalid calling parameters given to the ns_name_ntop() function.
Specifically, it detects if the caller passed a pointer and size pair
that causes the pointer to integer-wrap past zero.

! Fixed a fenceposting bug when a client had two host records configured,
one using 'uid' and the other using 'hardware ethernet'. CVE-2009-1892

Changes since 4.0.1

- Remove infinite loop in token_print_indent_concat().

- Validate the argument to the -p option.

- The notorious 'option <unknown> ... larger than buffer' log line,
which is seen in some malformed DHCP client packets, was modified.
It now logs the universe name, and does not log the length values
(which are bogus corruption read from the packet anyway). It also
carries a hopefully more useful explanation.

- Suppress spurious warnings from configure about --datarootdir

- A bug was fixed that caused the server not to answer some valid Solicit
and Request packets, if the dynamic range covering any requested addresses
had been deleted from configuration.

- Update the code to deal with GCC 4.3. This included two sets of changes.
The first is to the configuration files to include the use of
AC_USE_SYSTEM_EXTENSIONS. The second is to deal with return values that
were being ignored.

- Using reserved leases no longer results in 'lease with binding state
free not on its queue' error messages, thanks to a patch from Frode
Nordahl.

- DDNS removal routines were updated so that the DHCID is not removed until
the client has been deprived of all A and AAAA records (not only the last
one of either of those). This resolves a bug where dual stack clients
would not be able to regain their names after either expiration event.

- Two uninitialized stack structures are now memset to zero, thanks to
patch from David Cantrell at Red Hat.

- Fixed a cosmetic bug where pretty-printing valid domain-search options would
result in an erroneous error log message ('garbage in format string').

- A bug in DLPI packet transmission (Solaris, HP/UX) that caused the server
to stop receiving packets is fixed. The same fix also means that the MAC
address will no longer appear 'bogus' on DLPI-based systems.

- The update-conflict-detection feature would leave an FQDN updated without
a DHCID (still currently implemented as a TXT RR). This would cause later
expiration or release events to fail to remove the domain name. The feature
now also inserts the client's up to date DHCID record, so records may safely
be removed at expiration or release time. Thanks to a patch submitted by
Christof Chen.

- 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.

- Various compilation fixes have been included for the memory related
DEBUG #defines in includes/site.h.

- Fixed Linux client script 'unary operator expected' errors with DHCPv6.

- 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@xxxxx>.

- Fixed failover reconnection retry code to continue to retry to reconnect
rather than restarting the listener.

- Compilation on Solaris with USE_SOCKETS defined in includes/site.h has
been repaired. Other USE_ overrides should work better.

- A check for the local flavor of IFNAMSIZ had a broken 'else' condition,
that probably still resulted in the correct behaviour (but wouldn't use
a larger defined value provided by the host OS).
