They are no longer "all" digests, but only the "common" digests.
Part of 17795.
This is an automated patch I made with a couple of perl one-liners:
perl -i -pe 's/crypto_digest_all/crypto_common_digests/g;' src/*/*.[ch]
perl -i -pe 's/\bdigests_t\b/common_digests_t/g;' src/*/*.[ch]
An earlier version of these tests was broken; now they're a nicer,
more robust, more black-box set of tests. The key is to have each
test check a handshake message that is wrong in _one_ way.
Silence clang warnings under --enable-expensive-hardening, including:
+ implicit truncation of 64 bit values to 32 bit;
+ const char assignment to self;
+ tautological compare; and
+ additional parentheses around equality tests. (gcc uses these to
silence assignment, so clang warns when they're present in an
equality test. But we need to use extra parentheses in macros to
isolate them from other code).
Conflicts:
src/or/channel.c
src/or/circuitlist.c
src/or/connection.c
Conflicts involved removal of next_circ_id and addition of
unusable-circid tracking.
Instead of killing an or_connection_t that has had no circuits for
the last 3 minutes, give every or_connection_t a randomized timeout,
so that an observer can't so easily infer from the connection close
time the time at which its last circuit closed.
Also, increase the base timeout for canonical connections from 3
minutes to 15 minutes.
Fix for ticket 6799.
In C, it's a bad idea to do this:
char *cp = array;
char *end = array + array_len;
/* .... */
if (cp + 3 >= end) { /* out of bounds */ }
because cp+3 might be more than one off the end of the array, and
you are only allowed to construct pointers to the array elements,
and to an element one past the end. Instead you have to say
if (cp - array + 3 >= array_len) { /* ... */ }
or something like that.
This patch fixes two of these: one in process_versions_cell
introduced in 0.2.0.10-alpha, and one in process_certs_cell
introduced in 0.2.3.6-alpha. These are both tracked under bug
10363. "bobnomnom" found and reported both. See also 10313.
In our code, this is likely to be a problem as we used it only if we
get a nasty allocator that makes allocations end close to (void*)-1.
But it's best not to have to worry about such things at all, so
let's just fix all of these we can find.
This patch removes an "if (chan)" that occurred at a place where
chan was definitely non-NULL. Having it there made some static
analysis tools conclude that we were up to shenanigans.
This resolves#9979.
We were checking whether a 8-bit length field had overflowed a
503-byte buffer. Unless somebody has found a way to store "504" in a
single byte, it seems unlikely.
Fix for 10313 and 9980. Based on a pach by Jared L Wong. First found
by David Fifield with STACK.
The spec requires them to do so, and not doing so creates a situation
where they can't send-test because relays won't extend to them because
of the other part of bug 9546.
Fixes bug 9546; bugfix on 0.2.3.6-alpha.
Relays previously, when initiating a connection, would only send a
NETINFO after sending an AUTHENTICATE. But bridges, when receiving a
connection, would never send AUTH_CHALLENGE. So relays wouldn't
AUTHENTICATE, and wouldn't NETINFO, and then bridges would be
surprised to be receiving CREATE cells on a non-open circuit.
Fixes bug 9546.
When we moved channel_matches_target_addr_for_extend() into a separate
function, its sense was inverted from what one might expect, and we
didn't have a ! in one place where we should have.

Our ++ should have been += 2. This means that we'd accept version
numbers even when they started at an odd position.
This bug should be harmless in practice for so long as every version
number we allow begins with a 0 byte, but if we ever have a version
number starting with 1, 2, 3, or 4, there will be trouble here.
Fix for bug 8059, reported pseudonymously. Bugfix on 0.2.0.10-alpha
-- specifically, commit 6fcda529, where during development I
increased the width of a version to 16 bits without changing the
loop step.
