Here, have some terribly clever new buffer code. It uses a mbuf-like strategy rather than a ring buffer strategy, so it should require far far less extra memory to hold any given amount of data. Also, it avoids access patterns like x=malloc(1024);x=realloc(x,1048576);x=realloc(x,1024);append_to_freelist(x) that might have been contributing to memory fragmentation. I've tested it out a little on peacetime, and it seems to work so far. If you want to benchmark it for speed, make sure to remove the #define PARANOIA; #define NOINLINE macros at the head of the module.

edge_connection_t: want_onehop if it must attach to a circuit with
only one hop (e.g. for the current tunnelled connections that use
begin_dir), and use_begindir if we mean to use a BEGIN_DIR relay
command to establish the stream rather than the normal BEGIN. Now
we can make anonymized begin_dir connections for (e.g.) more secure
hidden service posting and fetching.

Make controllers accept LF as well as CRLF. Update spec to reflect this. Remove now-dead code. Make controller warning about v0 protocol more accurate.
svn:r11299
Weasel noticed that many buffers spend their time with empty 4k, 8k, and 16k memory chunks. Thus, be more aggressive about putting empty chunks on the freelist, regardless of their high water marks. (Also, run buffer_shrink_freelist on the 8k-chunk freelist.)

Sun CC likes to give warnings for the do { } while(0) construction for making statement-like macros. Define STMT_BEGIN/STMT_END macros that do the right thing, and use them everywhere.
svn:r10645
Initial version of code to stop using socket pairs for linked connections. Superficially, it seems to work, but it probably needs a lot more testing and attention.
svn:r9995
Remove support for v0 control protocol from 0.2.0.x trunk; send back error when we receive a v0 control message. (Leave "if(v1){...}"blocks indented for now so this patch is easier to read.) ((Finally, the linecount goes _down_ a little.))

Removing the last DOCDOC comment hurt so much that I had to use Doxygen to identify undocumented macros and comments, and add 150 more DOCDOCs to point out where they were. Oops. Hey, kids! Fixing some of these could be your first Tor patch!
svn:r9477
buffer, make sure our tls_get_forced_write_size doesn't
make it write whatever's after the buffer.
this hasn't triggered yet, but it would be rare, so let's
leave it in.
svn:r9107
New socks command CONNECT_DIR. New config option TunnelDirConns that
builds a circ ending at the directory server and delivers a BEGIN_DIR
cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.
svn:r9098
Add support for (Free?)BSD's natd, which was an old way to let you
have your firewall automatically redirect traffic. (Original patch
from Zajcev Evgeny, updated for 0.1.2.x by tup.)
