tor_sscanf() only handles %u and %s for now, which will make it
adequate to replace sscanf() for date/time/IP parsing. We want this
to prevent attackers from constructing weirdly formed descriptors,
cells, addresses, HTTP responses, etc, that validate under some
locales but not others.

The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed. They were not actually useful for
telling the version of Tor files in the wild.
svn:r17867
dmalloc_malloc, dmalloc_realloc and dmalloc_strdup. It only calls those
functions if we're using the magic USE_DMALLOC macro. If we're not doing
that, we call the normal malloc, realloc and strdup. This is my first
night at malloc disambiguation club, so I had to disambiguate. Also, first commit, I have my commit bit now. Huzzzah!!!
svn:r17157
Make generic address manipulation functions work better. Switch address policy code to use tor_addr_t, so it can handle IPv6. That is a good place to start.
svn:r16178
Fix for bug 742: do not use O_CREAT on 2-option version of open(). Especially do not use it on /dev/null. Fix from Michael Scherer. Bugfix on 0.0.2pre19 (wow).
svn:r15626
Fix all remaining shorten-64-to-32 errors in src/common. Some were genuine problems. Many were compatibility errors with libraries (openssl, zlib) that like predate size_t. Partial backport candidate.
svn:r13665
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
Write a new autoconf macro to test whether a function is declared. It is suboptimal and possibly buggy in some way, but it seems to work for me. use it to test for a declaration of malloc_good_size, so we can workaround operating systems (like older OSX) that have the function in their libc but do not deign to declare it in their headers. Should resolve bug 587.
svn:r13339
Another test for the increasingly bad check-spaces style checker to check: #else\n#if is almost a sure sign of a failure to use #elif. Fortunately, we only did that 3 times.
svn:r13039
Push the strdups used for parsing configuration lines into parse_line_from_string(). This will make it easier to parse more complex value formats, which in turn will help fix bug 557
svn:r13020
Use reference-counting to avoid allocating a zillion little addr_policy_t objects. (This is an old patch that had been sitting on my hard drive for a while.)
svn:r13017
New, slightly esoteric function, tor_malloc_roundup(). While tor_malloc(x) allocates x bytes, tor_malloc_roundup(&x) allocates the same size of chunk it would use to store x bytes, and sets x to the usable size of that chunk.
svn:r12981
Change tor_addr_t to be a tagged union of in_addr and in6_addr, not of sockaddr_in and sockaddr_in6. It's hardly used in the main code as it is, but let's get it right before it gets popular.
svn:r12660
Improved skew reporting: "You are 365 days in the duture" is more useful than "You are 525600 minutes in the future". Also, when we get something that proves we are at least an hour in the past, tell the controller "CLOCK_SKEW MIN_SKEW=-3600" rather than just "CLOCK_SKEW"
svn:r12283
Add a bunch of function documentation; clean up a little code; fix some XXXXs; tag the nonsensical EXTRAINFO_PURPOSE_GENERAL as nonsesnse; note another bit of "do not cache special routers" code to nuke.
svn:r11761
Refactor write_chunks_to_file_impl: break out the "pick a temporary name if it makes sense, and open the right filename" logic and the "close the file and unlink or rename if necessary" logic. This will let us write big files in a smarter way than "Build a big string" or "make a list of chunks", once we get around to using it.
svn:r11300
Add a new ClientDNSRejectInternalAddresses option (default: on) to refuse to believe that any address can map to or from an internal address. This blocks some kinds of potential browser-based attacks, especially on hosts using DNSPort. Also clarify behavior in some comments. Backport candiate?
svn:r11287
Glibc (and maybe others) define a mallinfo() that can be used to see how the platform malloc is acting inside. When we have it, dump its output on dumpmemusage().
svn:r10996
Another patch from croup: drop support for address masks that do not correspond to bit prefixes. Nobody has used this for a while, and we have given warnings for a long time.
svn:r10881
Patch from croup: rewrite the logic of get_next_token() to do the right thing with input that ends at weird places, or aligns with block boundaries after mmap. should fix bug 455. Needs fuzzing.
svn:r10847
Fix the fix for bug 445: set umask properly. Also use open+fdopen rather than just umask+fopen, and create authority identity key with mode 400.
svn:r10485
First bare stubs of ipv6 work: commit some (untested, hence doublessly broken) implementations of inet_ntop/pton for systems that lack them.
svn:r10326
Add math functions to round values to the nearest power of 2. Make mempools more careful about making sure that the size of their chunks is a little less than a power of 2, not a little more.
svn:r10304
More v3 directory code: have authorities load certificates; have everybody store certificates to disk and load them; provide a way to configure v3 authorities.
svn:r10293
Partial backport candidate: do not rely on finding a \0 after an mmaped() router/extrainfo file. Also, set journal length correctly when starting up.
svn:r10248
Track the number of connection_t separately from the number of open sockets. It is already possible to have connections that do not count: resolving conns, for one. Once we move from socketpairs to linked conns, and once we do dns proxying, there will be lots of such connections.
svn:r9994
Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)
svn:r9733
