8a4e543b51 ! 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.  [ISC-Bugs #19839]

e2624b82f1 - Reworked cons_options() and store_options() to fix a buffer

0c20eab3c8 - 'request' and 'also request' syntaxes have been added to accomodate 
the DHCPv6 client configuration.  'send dhcp6.oro' is no longer
  necessary.  [ISC-Bugs #17023]

af5fa17626 - Add support for dhcpv6 "Release" messages [rt16905] 
- Add -x option, which causes running dhclient processes to exist
  gracefully *without* releasing leases [rt16741]
(Merging both at once because the first one depended on the second one)

lists of 55 bytes in length no matter how long the declared PRL was.

8ea19a715c - dhclient will now fork() into the background once it binds to an 
IPv6 address, or immediately if the -n flag is supplised.
  [ISC-Bugs #16872]

- -q is now the default behaviour on dhclient, with -d or -v enabling
  non-quiet (stderr logging) mode.  [ISC-Bugs #16872]

23e10d3713 - A bug was fixed where the BOOTP header 'sname' field had a value, the 
copy written to persistent storage was actually the contents of the
  'file' field.  [ISC-Bugs #16784]

78c553c4a0 Removing the new I/O changes from HEAD. [ISC-Bugs #16328] 2006-08-09 14:57:48 +00:00
David Hankins
3004bebf47 - A new DDNS related server option, update-conflict-detection, has been 
added.  If this option is enabled, dhcpd will perform normal DHCID
  conflict resolution (the default).  If this option is disabled, it will
  instead trust the assigned name implicitly (removing any other bindings
  on that name).  This option has not been made available in dhclient.
  [ISC-Bugs #16165]

6cbc66298b - If the dhclient were to receive a DHCPNAK while it was in the RENEW 
state (and consequently, had an active, 'bound' address and related
  configuration options), it would fail to 'tear down' this information
  before proceeding into INIT state.  dhclient now iterates the dhclient-
  script with the 'EXPIRE' action to cause these teardowns prior to entering
  INIT state. [ISC-Bugs #16035]
 2006-07-09 15:39:48 +00:00

5e86441636 - A new common (server or client) option, 'db-time-format local;', has 
been added which prints the local time in /var/db/dhcpd.leases rather
  than UTC.  Thanks to a patch from Ken Lalonde. [ISC-Bugs #2678]

f7fdb21693 - Varying option space code and length bit widths (8/16/32) are now 
supported.  This is a milestone in acheiving RFC 3925 "VIVSO" and
  DHCPv6 support. [ISC-Bugs #15979]
 2006-06-01 20:23:18 +00:00

febbd40203 - The dhclient 'reject ...;' statement, which rejects leases given by named 
server-identifiers, now permits address ranges to be specified in CIDR
  notation. [ISC-Bugs #1435]

25b988c68f - The IO system now tracks all local IP addresses, so that the DHCP 
applications (particularly the dhcrelay) can discern between what frames
  were tranmsitted to it, and what frames are being carried through it which
  it should not intercept. [ISC-Bugs #15573]
