80d9737e70 Fix a segfault when a client is hup'd.
We need to make sure we have an event_base in dns.c before we call
anything that wants one. Make sure we always have one in dns_reset()
when we're a client. Fixes bug 1341.

c0d682686a Make tor_addr_copy() conform to memcpy requirements
The src and dest of a memcpy() call aren't supposed to overlap,
but we were sometimes calling tor_addr_copy() as a no-op.

Also, tor_addr_assign was a redundant copy of tor_addr_copy(); this patch
removes it.

fcbd65b45c Refactor the safe_str_*() API to make more sense.
The new rule is: safe_str_X() means "this string is a piece of X
information; make it safe to log."  safe_str() on its own means
"this string is a piece of who-knows-what; make it safe to log".

c210db0d41 Enhance pqueue so we can remove items from the middle.
This changes the pqueue API by requiring an additional int in every

0c1b3070cf Now that FOO_free(NULL) always works, remove checks before calling it. 2009-12-12 02:07:59 -05:00
Sebastian Hahn
3807db001d *_free functions now accept NULL
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

71cdd99dd7 Another event2 evdns fix. 2009-10-13 18:57:25 -04:00
Nick Mathewson
81eee0ecff Fix a crash when using evdns from Libevent 2.
When we tried to use the deprecated non-threadsafe evdns
interfaces in Libevent 2 without using the also-deprecated
event_init() interface, Libevent 2 would sensibly crash, since it
has no guess where to find the Libevent library.

Here we use the evdns_base_*() functions instead if they're
present, and fake them if they aren't.

1e709c79d1 Isolate Libevent API dependency to just main.c and dns.c in src/or.
The rest of the code was only including event.h so that it could see
EV_READ and EV_WRITE, which we were using as part of the
connection_watch_events interface for no very good reason.

e5b88dc83f Update Tor to use Libevent 2.0 APIs when available.
This patch adds a new compat_libevent.[ch] set of files, and moves our
Libevent compatibility and utilitity functions there.  We build them
into a separate .a so that nothing else in src/commmon depends on
Libevent (partially fixing bug 507).

Also, do not use our own built-in evdns copy when we have Libevent
2.0, whose evdns is finally good enough (thus fixing Bug 920).

b262e76563 Fix gprof bottlenecks on exit nodes found by Jacob.
Apparently all the stuff that does a linear scan over all the DNS
cache entries can get really expensive when your DNS cache is very
large.  It's hard to say how much this will help performance, since
gprof doesn't count time spent in OpenSSL or zlib, but I'd guess 10%.

Also, this patch removes calls to assert_connection_ok() from inside
the read and write callbacks, which are similarly unneeded, and a
little costlier than I'm happy with.

This is probably worth backporting to 0.2.0.

Specifically if you send SIGUSR1, it will add two lines to the log file:
May 22 07:41:59.576 [notice] Our DNS cache has 3364 entries.
May 22 07:41:59.576 [notice] Our DNS cache size is approximately 1022656
bytes.

Fix a longstanding dnsworker-related bug: when we decide to kill a DNS worker for having been in use too long, and we independently decide to close one of the exit connections waiting for that DNS worker (perhaps because we got an END relay cell), it was possible for us to try to double-free the connection.  We were smart enough to detect this and assert, but not smart enough to fix this bug before now.  This should resolve bug 390.  Backport candidate.

Instead of just checking known-invalid addresses for DNS hijacking, we
 now check randomly generated addresses, and if too many of them map to
 the same IP, we assume that IP is the destination of a DNS hijack
 attempt.
 
 A little bird tells me that some DNS hijackers think that declining to
 give an A record for RFC2606 addresses (like .invalid and .example)
 makes them more standards compliant.  Standardswise, this is like an
 illicit brothel making sure that nobody has pulled the tags off the
 mattresss, but that doesn't get us out of working around it.
