Changes since 4.2.0b1
- Prohibit including lease time information in a response to a DHCP INFORM.
[ISC-Bugs #21092]
! 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]
- A memory leak in ddns processing was closed. [ISC-Bugs #21377]
- Modify the exception handling for initial context creation. Previously
we would try and clean up before exiting. This could present problems
when the cleanup required part of the context that wasn't available. It
also didn't do much as we exited afterwards anyway. Now we simply log
the error and exit. [ISC-Bugs #21093]
- 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]
- Add some debugging output for use with the DDNS code. [ISC-Bugs #20916]
- Fix the trace code to handle timing events better and to truncate a file
before using instead of overwriting it. [ISC-Bugs #20969]
- Modify the determination of the default TTL to use for DDNS updates.
The user may still configure the ttl via ddns-ttl. The default for
both v4 and v6 is now 1/2 the (preferred) lease time with a limit. The
previous defaults (1/2 lease time without a limit for v4 and a default
value for v6) may be used by defining USE_OLD_DDNS_TTL in site.h
[ISC-Bugs #21126]
- libisc/libdns is now brought up to version 9.7.1rc1. This corrects
three reported flaws in ISC DHCP;
o DHCP processes (dhcpd, dhclient) fail to start if one of either the
IPv4 or IPv6 address families is not present. [ISC-Bugs #21122]
o Assertion failure when attempting to cancel a previously running DDNS
update. [ISC-Bugs #21133]
o Compilation failure of libisc/libdns due to the use of a flexible
array member. [ISC-Bugs #21316]
