Bitwise check for the BRIDGE_DIRINFO flag, rather than checking for
equality.
Fixes a (potential) bug where directories offering BRIDGE_DIRINFO,
and some other flag (i.e. microdescriptors or extrainfo),
would be ignored when looking for bridge directories.
Final fix in series for bug 13163.
Document usage of the NO_DIRINFO and ALL_DIRINFO flags clearly in functions
which take them as arguments. Replace 0 with NO_DIRINFO in a function call
for clarity.
Seeks to prevent future issues like 13163.
Stop using the default authorities in networks which provide both
AlternateDirAuthority and AlternateBridgeAuthority.
This bug occurred due to an ambiguity around the use of NO_DIRINFO.
(Does it mean "any" or "none"?)
Partially fixes bug 13163.
If (GNU) Make 3.81 is running processes in parallel using -j2 (or more),
it waits until all descendent processes have exited before it returns to
the shell.
When a command like "make -j2 test-network" is run, this means that
test-network.sh apparently hangs until it either make is forcibly
terminated, or all the chutney-launched tor processes have exited.
A workaround is to use make without -j, or make -j1 if there is an
existing alias to "make -jn" in the shell.
We resolve this bug in tor by using "chutney stop" after "chutney verify"
in test-network.sh.
Add a --delay option to test-network.sh, which configures the delay before
the chutney network tests for data transmission. The default remains at
18 seconds if the argument isn't specified.
Apparently we should be using bootstrap status for this (eventually).
Partially implements ticket 13161.
The default shell on OS X is bash, which has a builtin echo. When called
in "sh" mode, this echo does not accept "-n". This patch uses "/bin/echo -n"
instead.
Partially fixes issue 13161.
Add the TestingDirAuthVoteExit option, a list of nodes to vote Exit for,
regardless of their uptime, bandwidth, or exit policy.
TestingTorNetwork must be set for this option to have any effect.
Works around an issue where authorities would take up to 35 minutes to
give nodes the Exit flag in a test network, despite short consensus
intervals. Partially implements ticket 13161.
Fixes bug 13295; bugfix on 0.2.5.3-alpha.
The alternative here is to call crypto_global_init() from tor-resolve,
but let's avoid linking openssl into tor-resolve for as long as we
can.
When a spawned process forks, fails, then exits very quickly, (this
typically occurs when exec fails), there is a race condition between the
SIGCHLD handler updating the process_handle's fields, and checking the
process status in those fields. The update can occur before or after the
spawn tests check the process status.
We check whether the process is running or not running (rather than just
checking if it is running) to avoid this issue.
In circuit_build_times_calculate_timeout() in circuitstats.c, avoid dividing
by zero in the pareto calculations.
If either the alpha or p parameters are 0, we would divide by zero, yielding
an infinite result; which would be clamped to INT32_MAX anyway. So rather
than dividing by zero, we just skip the offending calculation(s), and
use INT32_MAX for the result.
Division by zero traps under clang -fsanitize=undefined-trap -fsanitize-undefined-trap-on-error.
Avoid 4 null pointer errors under clang shallow analysis (the default when
building under Xcode) by using tor_assert() to prove that the pointers
aren't null. Resolves issue 13284 via minor code refactoring.
c99 lets us do neat stuff like:
{
int j, k;
foo(&j, &k);
int z = j + k;
}
and also
struct point { int x; int y; };
struct point pt = { .x=5, .y=5 };
This commit makes the configure scripts check to make sure your
compiler implements them. It also disables our longstanding warning
about midblock declarations.
Closes ticket 13233.
When DisableNetwork is set, do not launch pluggable transport plugins,
and if any are running already, terminate the existing instances.
Resolves ticket 13213.
Allow clients to use optimistic data when connecting to a hidden service,
which should cut out the initial round-trip for client-side programs
including Tor Browser.
(Now that Tor 0.2.2.x is obsolete, all hidden services should support
server-side optimistic data.)
See proposal 181 for details. Implements ticket 13211.
Clients are now willing to send optimistic circuit data (before they
receive a 'connected' cell) to relays of any version. We used to
only do it for relays running 0.2.3.1-alpha or later, but now all
relays are new enough.
Resolves ticket 13153.
Return an error when the second or later arguments of the
"setevents" controller command are invalid events. Previously we
would return success while silently skipping invalid events.
Fixes bug 13205; bugfix on 0.2.3.2-alpha. Reported by "fpxnns".
Note that this will likely need to be folded with the changes file for #12751,
as this change is a mere fixup on top of the changes introduced for #12751.
Stop modifying the value of our DirReqStatistics torrc option just
because we're not a bridge or relay. This bug was causing Tor
Browser users to write "DirReqStatistics 0" in their torrc files
as if they had chosen to change the config.
Fixes bug 4244; bugfix on 0.2.3.1-alpha.
