* Fix (Open?)BSD fast-connect bug with optimistic data.Nick Mathewson2013-06-10
| | | | | | | | | | | | | | | There's an assertion failure that can occur if a connection has optimistic data waiting, and then the connect() call returns 0 on the first attempt (rather than -1 and EINPROGRESS). That latter behavior from connect() appears to be an (Open?)BSDism when dealing with remote addresses in some cases. (At least, I've only seen it reported with the BSDs under libevent, even when the address was 127.0.0.1. And we've only seen this problem in Tor with OpenBSD.) Fixes bug 9017; bugfix on 0.2.3.1-alpha, which first introduced optimistic data. (Although you could also argue that the commented-out connection_start_writing in 155c9b80 back in 2002 is the real source of the issue.)

| * Don't run off the end of the array-of-freelistsNick Mathewson2013-05-09
|/ | | | | | | | | | | | | This is a fix for bug 8844, where eugenis correctly notes that there's a sentinel value at the end of the list-of-freelists that's never actually checked. It's a bug since the first version of the chunked buffer code back in 0.2.0.16-alpha. This would probably be a crash bug if it ever happens, but nobody's ever reported something like this, so I'm unsure whether it can occur. It would require write_to_buf, write_to_buf_zlib, read_to_buf, or read_to_buf_tls to get an input size of more than 32K. Still, it's a good idea to fix this kind of thing!

| * | Add and use and unlikely-to-be-eliminated memwipe()Nick Mathewson2012-11-08
|/ / | | | | | | | | | | | | | | | | | | Apparently some compilers like to eliminate memset() operations on data that's about to go out-of-scope. I've gone with the safest possible replacement, which might be a bit slow. I don't think this is critical path in any way that will affect performance, but if it is, we can work on that in 0.2.4. Fixes bug 7352.
* | Fix a remotely triggerable assertion failure (CVE-2012-2250)Nick Mathewson2012-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | If we completed the handshake for the v2 link protocol but wound up negotiating the wong protocol version, we'd become so confused about what part of the handshake we were in that we'd promptly die with an assertion. This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha. All servers running that version or later should really upgrade. Bug and fix from "some guy from France." I tweaked his code slightly to make it log the IP of the offending node.

| * Fix binary search on lists of 0 or 1 element.Nick Mathewson2012-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation we added has a tendency to crash with lists of 0 or one element. That can happen if we get a consensus vote, v2 consensus, consensus, or geoip file with 0 or 1 element. There's a DOS opportunity there that authorities could exploit against one another, and which an evil v2 authority could exploit against anything downloading v2 directory information.. This fix is minimalistic: It just adds a special-case for 0- and 1-element lists. For 0.2.4 (the current alpha series) we'll want a better patch. This is bug 7191; it's a fix on 0.2.0.10-alpha.
* | Let 0.2.3 clients exit to internal addresses if they wantRoger Dingledine2012-10-23
| | | | | | | | | | | | | | Clients now consider the ClientRejectInternalAddresses config option when using a microdescriptor consensus stanza to decide whether an exit relay would allow exiting to an internal address. Fixes bug 7190; bugfix on 0.2.3.1-alpha.

| | | | | | | | | | | | | | | | | | | | | | Our implementation of parse_short_policy was screwed up: it would ignore the last character of every short policy. Obviously, that's broken. This patch fixes the busted behavior, and adds a bunch of unit tests to make sure the rest of that function is okay. Fixes bug 7192; fix on 0.2.3.1-alpha.

| * Disable TLS Session Tickets, which we were apparently getting for freeNick Mathewson2012-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenSSL 1.0.0 added an implementation of TLS session tickets, a "feature" that let session resumption occur without server-side state by giving clients an encrypted "ticket" that the client could present later to get the session going again with the same keys as before. OpenSSL was giving the keys to decrypt these tickets the lifetime of the SSL contexts, which would have been terrible for PFS if we had long-lived SSL contexts. Fortunately, we don't. Still, it's pretty bad. We should also drop these, since our use of the extension stands out with our non-use of session cacheing. Found by nextgens. Bugfix on all versions of Tor when built with openssl 1.0.0 or later. Fixes bug 7139.
