      Fix out-of-bound memory read in `tor_tls_cert_matches_key()` for NSS. · b46984e9
      Alexander Færøy authored and Nick Mathewson's avatar Nick Mathewson committed
      This patch fixes an out-of-bound memory read in
      `tor_tls_cert_matches_key()` when Tor is compiled to use Mozilla's NSS
      instead of OpenSSL.
      The NSS library stores some length fields in bits instead of bytes, but
      the comparison function found in `SECITEM_ItemsAreEqual()` needs the
      length to be encoded in bytes. This means that for a 140-byte,
      DER-encoded, SubjectPublicKeyInfo struct (with a 1024-bit RSA public key
      in it), we would ask `SECITEM_ItemsAreEqual()` to compare the first 1120
      bytes instead of 140 (140bytes * 8bits = 1120bits).
      This patch fixes the issue by converting from bits to bytes before
      calling `SECITEM_ItemsAreEqual()` and convert the `len`-fields back to
      bits before we leave the function.
      This patch is part of the fix for TROVE-2020-001.

      Preemptive circs should work with UseEntryGuards 0 · 39f2411b
      Roger Dingledine authored
      Resume being willing to use preemptively-built circuits when
      UseEntryGuards is set to 0. We accidentally disabled this feature with
      that config setting (in our fix for #24469), leading to slower load times.

      Appveyor: Copy required DLLs to test and app · 38e07b88
      teor authored
      Copy required DLLs to test and app, before running tor's tests.
      This ensures that tor.exe and test*.exe use the correct version of each
      DLL. This fix is not required, but we hope it will avoid DLL search
      issues in future.

      Fix TROVE-2020-003. · 089e57d2
      George Kadianakis authored and Nick Mathewson's avatar Nick Mathewson committed
      Given that ed25519 public key validity checks are usually not needed
      and (so far) they are only necessary for onion addesses in the Tor
      protocol, we decided to fix this specific bug instance without
      modifying the rest of the codebase (see below for other fix
      In our minimal fix we check that the pubkey in
      hs_service_add_ephemeral() is valid and error out otherwise.

      dos: Pass transport name on new client connection · 894ff2dc
      David Goulet authored
      For a bridge configured with a pluggable transport, the transport name is
      used, with the IP address, for the GeoIP client cache entry.
      However, the DoS subsystem was not aware of it and always passing NULL when
      doing a lookup into the GeoIP cache.
      This resulted in bridges with a PT are never able to apply DoS defenses for
      newly created connections.
      Fixes #33491

      Travis: Stop allowing stem test failures · 9d771ccc
      teor authored
      Stop allowing failures on the Travis CI stem tests job. It looks like
      all the stem hangs we were seeing are now fixed, but let's make sure we
      see them if they happen again.
      Closes ticket 33075.

      hs-v3: Remove a BUG() caused by an acceptable race · ed57a04a
      David Goulet authored
      hs_client_purge_state() and hs_cache_clean_as_client() can remove a descriptor
      from the client cache with a NEWNYM or simply when the descriptor expires.
      Which means that for an INTRO circuit being established during that time, once
      it opens, we lookup the descriptor to get the IP object but hey surprised, no
      more descriptor.
      The approach here is minimalist that is accept the race and close the circuit
      since we can not continue. Before that, the circuit would stay opened and the
      client wait the SockTimeout.
      Fixers #28970.
