This should keep WinCE working (unicode always-on) and get Win98
working again (unicode never-on).
There are two places where we explicitly use ASCII-only APIs, still:
in ntmain.c and in the unit tests.
This patch also fixes a bug in windoes tor_listdir that would cause
the first file to be listed an arbitrary number of times that was
also introduced with WinCE support.
Should fix bug 1797.
Setting CookieAuthFileGroupReadable but without setting CookieAuthFile makes
no sense, because unix directory permissions for the data directory prevent
the group from accessing the file anyways.
When this happens, run through the streams on the circuit and make
sure they're all blocked. If some aren't, that's a bug: block them
all and log it! If they all are, where did the cell come from? Log
it!
(I suspect that this actually happens pretty frequently, so I'm making
these log messages appear at INFO.)
If the voting interval was short enough, the two-minutes delay
of CONSENSUS_MIN_SECONDS_BEFORE_CACHING would confuse bridges
to the point where they would assert before downloading a consensus.
It it was even shorter (<4 minutes, I think), caches would
assert too. This patch fixes that by having replacing the
two-minutes value with MIN(2 minutes, interval/16).
Bugfix for 1141; the cache bug could occur since 0.2.0.8-alpha, so
I'm calling this a bugfix on that. Robert Hogan diagnosed this.
Done as a patch against maint-0.2.1, since it makes it hard to
run some kinds of testing networks.
With this patch we stop scheduling when we should write statistics using a
single timestamp in run_scheduled_events(). Instead, we remember when a
statistics interval starts separately for each statistic type in geoip.c
and rephist.c. Every time run_scheduled_events() tries to write stats to
disk, it learns when it should schedule the next such attempt.
This patch also enables all statistics to be stopped and restarted at a
later time.
This patch comes with a few refactorings, some of which were not easily
doable without the patch.
Once upon a time it made sense to keep all the Debian files in the
main Tor distribution, since repeatedly merging them back in was hard.
Now that we're on git, that's no longer so.
Peter's debian repository at debian/tor.git on our git server has the
most recent version of the tor-on-debian packaging stuff, and the versions
in our own repository have gotten out of date.
Resolves bug #1735.
We already had the country code ?? indicating an unknown country, so all we
needed to do to make unknown countries excludable was to make the ?? code
discoverable.
It's okay to get (say) a SocksPort line in the torrc, and then a
SocksPort on the command line to override it, and then a SocksPort via
a controller to override *that*. But if there are two occurrences of
SocksPort in the torrc, or on the command line, or in a single SETCONF
command, then the user is likely confused. Our old code would not
help unconfuse the user, but would instead silently ignore all but
the last occurrence.
This patch changes the behavior so that if the some option is passed
more than once to any torrc, command line, or SETCONF (each of which
coincidentally corresponds to a call to config_assign()), and the
option is not a type that allows multiple occurrences (LINELIST or
LINELIST_X), then we can warn the user.
This closes trac entry 1384.
At best, this patch helps us avoid sending queued relayed cells that
would get ignored during the time between when a destroy cell is
sent and when the circuit is finally freed. At worst, it lets us
release some memory a little earlier than it would otherwise.
Fix for bug #1184. Bugfix on 0.2.0.1-alpha.
Right now it says "552 internal error" because there's no way for
getinfo_helper_*() countries to specify an error message. This
patch changes the getinfo_helper_*() interface, and makes most of the
getinfo helpers give useful error messages in response to failures.
This should prevent recurrences of bug 1699, where a missing GeoIPFile
line in the torrc made GETINFO ip-to-county/* fail in a "not obvious
how to fix" way.
V3 authorities no longer decide not to vote on Guard+Exit. The bandwidth
weights should take care of this now.
Also, lower the max threshold for WFU to 0.98, to allow more nodes to become
guards.
This should make us conflict less with system files named "log.h".
Yes, we shouldn't have been conflicting with those anyway, but some
people's compilers act very oddly.
The actual change was done with one "git mv", by editing
Makefile.am, and running
find . -name '*.[ch]' | xargs perl -i -pe 'if (/^#include.*\Wlog.h/) {s/log.h/torlog.h/; }'
These timers behave better with non-monotonic clocks than our old
ones, and also try harder to make once-per-second events get called
one second apart, rather than one-plus-epsilon seconds apart.
This fixes bug 943 for everybody using Libevent 2.0 or later.
From the code:
zlib 1.2.4 and 1.2.5 do some "clever" things with macros. Instead of
saying "(defined(FOO) ? FOO : 0)" they like to say "FOO-0", on the theory
that nobody will care if the compile outputs a no-such-identifier warning.
Sorry, but we like -Werror over here, so I guess we need to define these.
I hope that zlib 1.2.6 doesn't break these too.
Possible fix for bug 1526.
This should never happen unless openssl is buggy or some of our
assumptions are deeply wrong, but one of those might have been the
cause of the not-yet-reproducible bug 1209. If it ever happens again,
let's get some info we can use.
Previously, we said (more or less), "a2x is broken and here's how you could
try to fix it". Instead, we now say "We need a2x to build manpages; a2x
didn't work; here is a fix that might work for you; alternatively you
could just skip manpage building."
Addresses bug 1524.
Also, give the message as a here-document rather than a bunch of echos.
In rare cases, we could cannibalize a one-hop circuit, ending up
with a two-hop circuit. This circuit would not be actually used,
but we should prevent its creation in the first place.
Thanks to outofwords and swissknife for helping to analyse this.
This patch adds support for two new configure options:
'--enable-gcc-hardening'
This sets CFLAGS to include:
"-D_FORTIFY_SOURCE=2 -fstack-protector-all"
"-fwrapv -fPIE -Wstack-protector -Wformat -Wformat-security"
"-Wpointer-sign"
It sets LDFLAGS to include:
"-pie"
'--enable-linker-hardening'
This sets LDFLAGS to include:
" -z relro -z now"
The main changes are to explain how we use git branches, how we use
changes files, and what should go into a patch. Putting these in
HACKING means that we shouldn't need to constantly refer to the or-dev
emails where we explain this stuff.
