George Kadianakis notes that if you give crypto_rand_int() a value
above INT_MAX, it can return a negative number, which is not what
the documentation would imply.
The simple solution is to assert that the input is in [1,INT_MAX+1].
If in the future we need a random-value function that can return
values up to UINT_MAX, we can add one.
Fixes bug 3306; bugfix on 0.2.2pre14.
When we added the check for key size, we required that the keys be
128 bytes. But RSA_size (which defers to BN_num_bytes) will return
128 for keys of length 1017..1024. This patch adds a new
crypto_pk_num_bits() that returns the actual number of significant
bits in the modulus, and uses that to enforce key sizes.
Also, credit the original bug3318 in the changes file.
When we introduced NEED_KEY_1024 in routerparse.c back in
0.2.0.1-alpha, I forgot to add a *8 when logging the length of a
bad-length key.
Bugfix for 3318 on 0.2.0.1-alpha.
Previously we did this nearer to the end (in the old_options &&
transition_affects_workers() block). But other stuff cares about
keys being consistent with options... particularly anything which
tries to access a key, which can die in assert_identity_keys_ok().
Fixes bug 3228; bugfix on 0.2.2.18-alpha.
Fixes part of #1297; bugfix on 48e0228f1e,
when circuit_expire_building was changed to assume that timestamp_dirty
was set when a circuit changed purpose to _C_REND_READY. (It wasn't.)
This situation can happen easily if you set 'ORPort auto' and
'AccountingMax'. Doing so means that when you have no ORPort, you
won't be able to set an ORPort in a descriptor, so instead you would
just generate lots of invalid descriptors, freaking out all the time.
Possible fix for 3216; fix on 0.2.2.26-beta.
We had all the code in place to handle this right... except that we
were unconditionally opening a PF_INET socket instead of looking at
sa_family. Ow.
Fixes bug 2574; not a bugfix on any particular version, since this
never worked before.
Most instances were dead code; for those, I removed the assignments.
Some were pieces of info we don't currently plan to use, but which
we might in the future. For those, I added an explicit cast-to-void
to indicate that we know that the thing's unused. Finally, one was
a case where we were testing the wrong variable in a unit test.
That one I fixed.
This resolves bug 3208.
It used to mean "Force": it would tell tor-resolve to ask tor to
resolve an address even if it ended with .onion. But when
AutomapHostsOnResolve was added, automatically refusing to resolve
.onion hosts stopped making sense. So in 0.2.1.16-rc (commit
298dc95dfd), we made tor-resolve happy to resolve anything.
The -F option stayed in, though, even though it didn't do anything.
Oddly, it never got documented.
Found while fixing GCC 4.6 "set, unused variable" warnings.
On win64, sockets are of type UINT_PTR; on win32 they're u_int;
elsewhere they're int. The correct windows way to check a socket for
being set is to compare it with INVALID_SOCKET; elsewhere you see if
it is negative.
On Libevent 2, all callbacks take sockets as evutil_socket_t; we've
been passing them int.
This patch should fix compilation and correctness when built for
64-bit windows. Fixes bug 3270.
We used to regenerate our descriptor whenever we'd get a sighup. This
was caused by a bug in options_transition_affects_workers() that would
return true even if the options were exactly the same. Down the call
path we'd call init_keys(), which made us make a new descriptor which
the authorities would reject, and the node would subsequently fall out
of the consensus.
This patch fixes only the first part of this bug:
options_transition_affects_workers() behaves correctly now. The second
part still wants a fix.
