BIND 9.4.2-P2 is now available.
This is the SECOND security patch for BIND 9.4.2, addressing
performance and stability issues in BIND 9.4.2-P1. Key features
are as follows:
- performance improvement over the P1 releases, namely
+ significantly remedying the port allocation issues
+ allowing TCP queries and zone transfers while issuing as many
outstanding UDP queries as possible
+ additional security of port randomization at the same level as P1
NOTE: There are some remaining stability problems in 9.4.2-P2 when
running under Microsoft Windows. A fix has been implemented, but
missed the cutoff time for this release; it will be addressed in a
Windows-specific release very soon.

Changes since 9.4.2-P1:
--- 9.4.2-P2 released ---
2406. [bug] Some operating systems have FD_SETSIZE set to a
low value by default, which can cause resource
exhaustion when many simultaneous connections are
open. Linux in particular makes it difficult to
increase this value. To use more sockets with
select(), set ISC_SOCKET_FDSETSIZE. Example:
STD_CDEFINES="[EMAIL PROTECTED]" ./configure
(This should not be necessary in most cases, and
never for an authoritative-only server.) [RT #18328]
2404. [port] hpux: files unlimited support.
2403. [bug] TSIG context leak. [RT #18341]
2402. [port] Support Solaris 2.11 and over. [RT #18362]
2401. [bug] Expect to get E[MN]FILE errno internal_accept()
(from accept() or fcntl() system calls). [RT #18358]
2399. [bug] Abort timeout queries to reduce the number of open
UDP sockets. [RT #18367]
2398. [bug] Improve file descriptor management. New,
temporary, named.conf option reserved-sockets,
default 512. [RT #18344]
2396. [bug] Don't set SO_REUSEADDR for randomized ports.
[RT #18336]
2395. [port] Avoid warning and no effect from "files unlimited"
on Linux when running as root. [RT #18335]
2394. [bug] Default configuration options set the limit for
open files to 'unlimited' as described in the
documentation. [RT #18331]
2392. [bug] remove 'grep -q' from acl test script, some platforms
don't support it. [RT #18253]
2322. [port] MacOS: work around the limitation of setrlimit()
for RLIMIT_NOFILE. [RT #17526]
