Roger spotted this on tor-dev in his comments on proposal 221.
(Actually, detect DESTROY vs everything else, since arma likes
network timeout indicating failure but not overload indicating failure.)
This function is supposed to construct a list of all the ciphers in
the "v2 link protocol cipher list" that are supported by Tor's
openssl. It does this by invoking ssl23_get_cipher_by_char on each
two-byte ciphersuite ID to see which ones give a match. But when
ssl23_get_cipher_by_char cannot find a match for a two-byte SSL3/TLS
ciphersuite ID, it checks to see whether it has a match for a
three-byte SSL2 ciphersuite ID. This was causing a read off the end
of the 'cipherid' array.
This was probably harmless in practice, but we shouldn't be having
any uninitialized reads.
(Using ssl23_get_cipher_by_char in this way is a kludge, but then
again the entire existence of the v2 link protocol is kind of a
kludge. Once Tor 0.2.2 clients are all gone, we can drop this code
entirely.)
Found by starlight. Fix on 0.2.4.8-alpha. Fixes bug 12227.
Authorities now assign the Guard flag to the fastest 25% of the
network (it used to be the fastest 50%). Also raise the consensus
weight that guarantees the Guard flag from 250 to 2000. For the
current network, this results in about 1100 guards, down from 2500.
This step paves the way for moving the number of entry guards
down to 1 (proposal 236) while still providing reasonable expected
performance for most users.
Implements ticket 12690.
Found because LibreSSL has OPENSSL_NO_COMP always-on, but this
conflicts with the way that _we_ turn off compression. Patch from
dhill, who attributes it to "OpenBSD". Fixes bug 12602; bugfix on
0.2.1.1-alpha, which introduced this turn-compression-off code.
- Don't try to rm -rf the directory before we start: somebody might
have set it to ~, which would be quite sad.
- Always quote the directory name
- Use 'make reset-gcov' before running tests.
- Use 'make check', not ./src/test/test
The extra \ is harmless, but mildly unpleasant.
Fixes 12392; bugfix on 0.2.2.25-alpha where we started using
GetTempDir(). Based on a patch by Gisle Vanem.
Otherwise, it always seems as though our Exclude* options have
changed, since we're comparing modified to unmodified values.
Patch from qwerty1. Fixes bug 9801. Bugfix on 0.2.4.10-alpha, where
GeoIPExcludeUnknown was introduced.
