Move in-addr.arpa parsing and generation into address.c, and simplify the code that does it elsewhere.  Incidentally, this lets exit servers answer requests for ip6.arpa addresses.

Fix a logic error that would automatically reject all but the first configured DNS server.  Bugfix on 0.2.1.5-alpha.  Possible fix for part of 813/868.  Spotted by coderman

svn:r17569

Consider GetNetworkParams() nameserver parsing to have suceeded if even one nameserver can be added.  Log more useful info about what exactly is failing when we fail to add a nameserver.

svn:r17368

Implement the 0x20-hack to make DNS poisoning harder against us, especially when resolving large names.  Add a cfg option to disable it, since apparently 3/10 of a percent of servers get it wrong.

svn:r17171

svn:r17050

Oops; we need to make sure that DNS request names are matched in the _questions_ section of the replies.  Rejecting answers whether the _answers_ section did not match made us reject A records waiting at the end of a CNAME record.  Bug 823.

svn:r16759

svn:r16627

 Make dns resolver code more robust: handle nameservers with IPv6 addresses, make sure names in replies match requested names, make sure origin address of reply matches the address we asked.


svn:r16621

 Fix the last of the -Wshorten-64-to-32 warnings.


svn:r13696

 Fix all -Wshorten-64-to-32 warnings that appear on my macbook.


svn:r13662

 Oops. not supposed to use tor_assert() in eventdns.c


svn:r13622

 Make the last of the veracode warning issues get fixed.


svn:r13620

 Fix all but 2 DOCDOC items; defer many XXX020s (particularly those where fixing them would fix no bugs at the risk of introducing some bugs).


svn:r13529

 Fix some warnings identified by building with -D_FORTIFY_SOURCE=2.  Remove a redundant (and nuts) definition of _FORTIFY_SOURCE from eventdns.c.


svn:r13424

 Remove or downgrade some XXX020 items.


svn:r13388

 Fixes to more anonymously-reported typos and logic errors.


svn:r13136

 add some missing checks for failing return values.


svn:r13130

 Carry a new evdns function over from libevent: do not rely on compile-time code to set the transaction ID correctly.  This will be important when we finally drop our internal copy of eventdns.c


svn:r11517

 remove yet more pointless differences between our eventdns.c and the evdns.c in libevent.


svn:r11425

 remove more pointless differences between our eventdns.c and the evdns.c in libevent.


svn:r11416

 Change comments in eventdns.c to C-style, so we can more easily diff it against the version in libevent to reconcile them (again).


svn:r11415

 Fix a couple of memory leaks in eventdns.c; found by niels.  Not backport candidates, since they only affect DNSPort users.


svn:r11413

 Compile without warnings on MinGW, even with --enable-gcc-warnings enabled.


svn:r11157

 Include fewer redundant headers; use the compiler search paths better.


svn:r11060

 Make buffer large enough to hold ip6.arpa addresses.  This code was not actually used yet, so no user-visible bug existed. (Based on patch by croup.)


svn:r10928

 Use tor malloc replacements in eventdns.c for now: there might be goblins there...goblins that only dmalloc can find!


svn:r10912

 Apparently, this problem can occur on the whole BSD family. "Yay."


svn:r10884

 Fix solaris eventdns.c behavior.  This time, I think I got it.  We were redefining _FILE_OFFSET_BITS, and thereby calling fstat64() on a struct stat, or something like that.


svn:r10643

 Patch from Tup: treat RESOLVED_TYPE_ERROR_TRANSIENT as a SERVERFAILED, and RESOLVED_TYPE_ERROR as NOTEXIST.  Generate transient/nontransient errors more sensibly.  Set flags better on DNS replies.


svn:r10427

 Aaargh.  Revert accidentally-committed debugging code in last patch.


svn:r10400

 Fix handling of resolves with very long or otherwise malformed addresses, and comment dns_resolve better, and stop making what should be a BUG warning into an assert(0).  This fixes bug 427, which was introduced around 9900/9931/9932.  Not a backport candidate: 0.1.2.x never had this bug.


svn:r10399

 Merge an evdns fix from libevent r357: "evdns_shutdown fix from adam langley.


svn:r10387

 socklen_t is a silly type anyway. Just use int as the argument for evdns_server_request_get_requesting_addr.


svn:r10347

 Fix some eventdns dns server bugs, and add a new eventdns function to get the address of whoever requested this lookup.


svn:r10316

 Bugfix and possible backport candidate: use the same logic as in read_all when reading resolv.conf.  Maybe this fixes bug 433.


svn:r10237

 Fix GCC warnings related to local parameters/variables getting shadowed.
