The crash (#37591) seems to happen because the query is taken out of
lookup->q(query->link), and put on lookup->connecting(query->clink).
The code checks query->link where it is detached (-1 in next pointer).
However, there's no need to call send_tcp_connect() there as the queries
are already connecting at that point.
4006. [security] A flaw in delegation handling could be exploited
to put named into an infinite loop. This has
been addressed by placing limits on the number
of levels of recursion named will allow (default 7),
and the number of iterative queries that it will
send (default 50) before terminating a recursive
query (CVE-2014-8500).
The recursion depth limit is configured via the
"max-recursion-depth" option. [RT #35780]
4003. [security] When geoip-directory was reconfigured during
named run-time, the previously loaded GeoIP
data could remain, potentially causing wrong
ACLs to be used or wrong results to be served
based on geolocation. [RT #37720]
4002. [security] Lookups in GeoIP databases that were not
loaded could cause an assertion failure.
[RT #37679]
4001. [security] The caching of GeoIP lookups did not always
handle address families correctly, potentially
resulting in an assertion failure. [RT #37672]
4005. [func] The buffer used for returning text from rndc
commands is now dynamically resizable, allowing
arbitrarily large amounts of text to be sent back
to the client. (Prior to this change, it was
possible for the output of "rndc tsig-list" to be
truncated.) [RT #37731]
3999. [func] "mkeys" and "nzf" files are now named after
their corresponding views, unless the view name
contains characters that would be incompatible
with use in a filename (i.e., slash, backslash,
or capital letters). If a view name does contain
these characters, the files will still be named
using a cryptographic hash of the view name.
Regardless of this, if a file using the old name
format is found to exist, it will continue to be
used. [RT #37704]
