Do the last part of arma's fix for bug 437: Track the origin of every addrmap, and use this info so we can remove all the trackhostexits-originated mappings for a given exit.

example, when answering a directory request), reset the
time-to-give-up timeout every time we manage to write something
on the socket. Bugfix on 0.1.2.x.
svn:r13643
Fix a bug that kept buf_find_string_offset from finding a string at the very end of the buffer. Add a unit test for this. Also, do not save a pointer to a chunk that might get reallocated by buf_pullup().
svn:r13635
add a flag to suppress overwriting the certificates file with new certificates, so we do not overwrite all certs when starting as an authority.
svn:r13630
Apply patch from Sebastian Hahn: stop imposing an arbitrary maximum on the number of file descriptors used for busy servers. Bug reported by Olaf Selke.
svn:r13626
Add some checks in torgzip.c to make sure we never overflow size_t there. Also make sure we do not realloc(list,0) in container.c. Backport candidate.
svn:r13587
would stop building circuits and start refusing connections after
24 hours, since we false believed that Tor was dormant. Reported
by nwf; bugfix on 0.1.2.x.
svn:r13583
Add openbsd memory allocator discussed in bug 468, to make it easier for linux users to get non-awful allocation patterns. Use --enable-openbsd-malloc to turn it on. Needs more testing.
svn:r13544
Re-tune mempool parametes based on testing on peacetime: use smaller chuncks, free them a little more aggressively, and try very hard to concentrate allocations on fuller chunks. Also, lots of new documentation.
svn:r13484
Add a bunch more code documentation; change the interface of fetch_var_cell_from_buf() so it takes the current link protocol into account and can't get confused by weird command bytes on v1 connections.
svn:r13430
Add a couple of (currently disabled) strategies for trying to avoid using too much ram in memory pools: prefer putting new cells in almost-full chunks, and be willing to free the last empty chunk if we have not needed it for a while. Also add better output to mp_pool_log_status to track how many mallocs a given memory pool strategy is saving us, so we can tune the mempool parameters.
svn:r13428
Be more thorough about memory poisoning and clearing. Add an in-place version of aes_crypt in order to remove a memcpy from relay_crypt_one_payload.
svn:r13414
Initial attempts to track down bug 600, and refactor possibly offending code. 1) complain early if circuit state is set to OPEN when an onionskin is pending. 2) refactor onionskin field into one only used when n_conn is pending, and a separate onionskin field waiting for attention by a cpuworker. This might even fix the bug. More likely, it will make it fail with a more useful core.
svn:r13394
Fix some XXX020 items in control.c: add a maximum line length and note that the number of versioning authorities is no longer apparent to clients.
svn:r13390
Periodically check whether we have an expired consensus networkstatus. If we do, and we think we have enough directory info, then call router_dir_info_changed(). Fixes bug 401. This bug was deferred from 0.1.2.x, but fixing it there is nontrivial.
svn:r13342
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
Fix bug 597: stop telling people to email Tor-ops. Also give a better suggestion when some other identity has been assigned the nickname we are using.
svn:r13337
Tor can warn and/or refuse connections to ports commonly used with
vulnerable-plaintext protocols.
We still need to figure out some good defaults for them.
svn:r13198
Fix an assert if we post a general-purpose descriptor via the
control port but that descriptor isn't mentioned in our current
network consensus. Bug reported by Jon McLachlan; bugfix on
0.2.0.9-alpha.
svn:r13153
If we do not serve v2 directory info, and our cached v2 networkstatus files are very old, remove them. If the directory is old, remove that too. (We already did this for obsolete routers files.)
svn:r13096
Add a manual page for tor-gencert. Also implement the missing -s option in tor-gencert, and fix the info message for when no cert file is specified.
svn:r13091
Change set_current_consensus interface to take a flags variable. Do not try to fetch certificates until after we have tried loading the fallback consensus. Should fix bug 583.
svn:r13058
Bugfix on fix for 557: Make values containing special characters work right with getconf, setconf, and saveconf. Document this in control-spec.txt
svn:r13056
Consequence of fix for 539: when a client gets a 503 response with a nontrivial body, pretend it got a 200 response. This lets clients use information erroneously sent to them by old buggy servers.
svn:r13054
Fix bug 579: Count DNSPort and hidden services when checking whether Tor is going to do anything. Change "no configured ports" from fatal to warning.
svn:r13036
Fix bug 575: protect the list of logs with a mutex. I couldn't find any appreciable change in logging performance on osx, but ymmv. You can undef USE_LOG_MUTEX to see if stuff gets faster for you.
svn:r13019
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
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.
svn:r12983
for a v2 or v3 networkstatus object before we were prepared. This
was particularly bad for 0.2.0.13 and later bridge relays, who
would never have a v2 networkstatus and would thus always crash
when used. Bugfixes on 0.2.0.x.
Estimate the v3 networkstatus size more accurately, rather than
estimating it at zero bytes and giving it artificially high priority
compared to other directory requests. Bugfix on 0.2.0.x.
svn:r12952
When we load a bridge descriptor from the cache,
and it was previously unreachable, mark it as retriable so we won't
just ignore it. Also, try fetching a new copy immediately.
svn:r12950
Handle cross-compilation more sanely: avoid most uses of the (never-defined!) CROSS_COMPILE variable; in the one place where we cannot help it, use the correct cross_compiling.
svn:r12945
time you use a given introduction point for your service, but
on subsequent requests we'd be using garbage memory. Fixed by
Karsten Loesing. Bugfix on 0.2.0.12-alpha.
svn:r12913
unexpected (it used to be in our networkstatus when we started
fetching it, but it isn't in our current networkstatus), and we
aren't using bridges. Bugfix on 0.2.0.x.
svn:r12911
create the "cached-status" directory in their datadir. All Tors
used to create it. Bugfix on 0.1.2.x.
Bridge relays with DirPort set to 0 no longer cache v1 or v2
directory information; there's no point. Bugfix on trunk.
svn:r12887
When we decide to send a 503 in response to a request for server descriptors, disable spooling so that we do not then send the descriptors anyway. Fixes bug 539.
svn:r12882
AlternateBridgeAuthority, and AlternateHSAuthority) that let the
user selectively replace the default directory authorities, rather
than the all-or-nothing replacement that DirServer offers.

using bridges or we have StrictEntryNodes set), don't mark relays
down when they fail a directory request. Otherwise we're too quick
to mark all our entry points down.
svn:r12755
authorities to mark certain relays as "bad directories" in the
networkstatus documents. Also supports the "!baddir" directive in
the approved-routers file.
svn:r12754
downloading new consensus documents. Bridge users now wait until
the end of the interval, so their bridge will be sure to have a
new consensus document.
svn:r12696
running an obsolete version, it used the string "OLD" to describe
it. Yet the "getinfo" interface used the string "OBSOLETE". Now use
"OBSOLETE" in both cases.
