-Subject: [PATCH 01/11] Impove cache behaviour for TCP connections.
-
-For ease of implementaion, dnsmasq has always forked a new process to
-handle each incoming TCP connection. A side-effect of this is that any
-DNS queries answered from TCP connections are not cached: when TCP
-connections were rare, this was not a problem.  With the coming of
-DNSSEC, it's now the case that some DNSSEC queries have answers which
-spill to TCP, and if, for instance, this applies to the keys for the
-root then those never get cached, and performance is very bad.  This
-fix passes cache entries back from the TCP child process to the main
-server process, and fixes the problem.

-Subject: [PATCH 03/11] Remove ability to compile without IPv6 support.
-
-This was the source of a large number of #ifdefs, originally
-included for use with old embedded libc versions. I'm
-sure no-one wants or needs IPv6-free code these days, so this
-is a move towards more maintainable code.

-
-The above is intended to increase robustness, but actually does the
-opposite. The problem is that by ignoring SERVFAIL messages and hoping
-for a better answer from another of the servers we've forwarded to,
-we become vulnerable in the case that one or more of the configured
-servers is down or not responding.
-
-Consider the case that a domain is indeed BOGUS, and we've send the
-query to n servers. With 68f6312d4bae30b78daafcd6f51dc441b8685b1e
-we ignore the first n-1 SERVFAIL replies, and only return the
-final n'th answer to the client. Now, if one of the servers we are
-forwarding to is down, then we won't get all n replies, and the
-client will never get an answer! This is a far more likely scenario
-than a temporary SERVFAIL from only one of a set of notionally identical
-servers, so, on the ground of robustness, we have to believe
-any SERVFAIL answers we get, and return them to the client.
-
-The client could be using the same recursive servers we are,

-Subject: [PATCH 11/11] Free config file values on parsing errors.
-
-This time I have a little bit more controversal patches. But I think
-still useful. They fixes memory leaks that might occur in some cases.
-Most dnsmasq errors is fatal, so it does not matter. But some are not.
-Some parts are reloaded on SIGHUP signal, so it might leak more than once.
-
-Some example when it changes the failures. Use dhcp-options file with
-this content:
-
-tag:error,vendor:redhat
-option:ntp-server,1.2.3.4.5
-option6:ntp-server,[:::]
-
-Is not fatal and dnsmasq will start. On each reload command, it would
-leak some memory. I validated it using valgrind --leak-check=full
-dnsmasq -d. This patch fixes it. It introduces something that might be
-considered constructor and destructor of selected structures.
