The three functions has been modeled after the arc4random family of
functions, and they will always return random bytes.
The isc_random family of functions internally use these CSPRNG (if available):
1. getrandom() libc call (might be available on Linux and Solaris)
2. SYS_getrandom syscall (might be available on Linux, detected at runtime)
3. arc4random(), arc4random_buf() and arc4random_uniform() (available on BSDs and Mac OS X)
4. crypto library function:
4a. RAND_bytes in case OpenSSL
4b. pkcs_C_GenerateRandom() in case PKCS#11 library
gsskrb5_register_acceptor_identity() by setting
the KRB5_KTNAME environment variable to the
contents of tkey-gssapi-keytab. Also fixed
test errors on MacOSX. [RT #22853]
- nsupdate can now get the default realm from
the user's Kerberos principal
- corrected gsstest compilation flags
- improved documentation
- fixed some NULL dereferences

2988. [experimental] Added a "dlopen" DLZ driver, allowing the creation
of external DLZ drivers that can be loaded as
shared objects at runtime rather than linked with
named. Currently this is switched on via a
compile-time option, "configure --with-dlz-dlopen".
Note: the syntax for configuring DLZ zones
is likely to be refined in future releases.

2987. [func] Improve ease of configuring TKEY/GSS updates by
adding a "tkey-gssapi-keytab" option. If set,
updates will be allowed with any key matching
a principal in the specified keytab file.
"tkey-gssapi-credential" is no longer required
and is expected to be deprecated. (Contributed

[RT #22629]
- added LRU expiration for generated TSIGs
- added the ability to use a non-default realm
- added new "realm" keyword in nsupdate
- limited lifetime of generated keys to 1 hour
or the lifetime of the context (whichever is
smaller)
