Edward Thomson 75a4636f 2015-05-29T16:56:38 git__tolower: a tolower() that isn't dumb Some brain damaged tolower() implementations appear to want to take the locale into account, and this may require taking some insanely aggressive lock on the locale and slowing down what should be the most trivial of trivial calls for people who just want to downcase ASCII.
Carlos Martín Nieto 02b4c1e2 2014-11-01T16:58:20 Port the TCP transport to the new stream API
Carlos Martín Nieto 1b75c29e 2014-11-02T11:17:01 gitno: remove code which is no longer needed Most of the network-facing facilities have been copied to the socket and openssl streams. No code now uses these functions directly anymore, so we can now remove them.
Carlos Martín Nieto 22fbb265 2014-11-02T16:12:10 netops: return GIT_ECERTIFICATE when it fails the basic tests When we first ask OpenSSL to verify the certfiicate itself (rather than the HTTPS specifics), we should also return GIT_ECERTIFICATE. Otherwise, the caller would consider this as a failed operation rather than a failed validation and not call the user's own validation.
William Swanson d0cf1040 2014-09-24T12:01:14 Correctly handle getaddrinfo return result The getaddrinfo function indicates failure with a non-zero return code, but this code is not necessarily negative. On platforms like Android where the code is positive, a failed call causes libgit2 to segfault.
Carlos Martín Nieto 41698f22 2014-09-11T10:04:05 net: remove support for outright ignoring certificates This option make it easy to ignore anything about the server we're connecting to, which is bad security practice. This was necessary as we didn't use to expose detailed information about the certificate, but now that we do, we should get rid of this. If the user wants to ignore everything, they can still provide a callback which ignores all the information passed.
Carlos Martín Nieto 9b940586 2014-07-04T12:45:43 Provide a callback for certificate validation If the certificate validation fails (or always in the case of ssh), let the user decide whether to allow the connection. The data structure passed to the user is the native certificate information from the underlying implementation, namely OpenSSL or WinHTTP.
Jacques Germishuys 90c2b37f 2014-07-05T21:22:56 in_addr is defined in <Winsock2.h>, include before <ws2tcpip.h>
Carlos Martín Nieto 1380e7c6 2014-07-03T02:34:32 netops: error out on url without a path In order to connect to a remote server, we need to provide a path to the repository we're interested in. Consider the lack of path in the url an error.
Carlos Martín Nieto 081e76ba 2014-06-12T16:20:52 ssl: init everything all the time Bring together all of the OpenSSL initialization to git_threads_init() so it's together and doesn't need locks. Moving it here also gives us libssh2 thread safety (when built against openssl).
Carlos Martín Nieto cf15ac8a 2014-06-12T03:20:34 ssl: cargo-cult thread safety OpenSSL's tests init everything in the main thread, so let's do that.
Carlos Martín Nieto 5fa04943 2014-06-11T23:19:48 ssl: use locking When using in a multithreaded context, OpenSSL needs to lock, and leaves it up to application to provide said locks. We were not doing this, and it's just luck that's kept us from crashing up to now.
Carlos Martín Nieto 1d3364ac 2014-06-11T20:52:15 netops: init OpenSSL once under lock The OpenSSL init functions are not reentrant, which means that running multiple fetches in parallel can cause us to crash. Use a mutex to init OpenSSL, and since we're adding this extra checks, init it only once.
Albert Meltzer 7c57cd97 2014-05-12T20:25:44 Win32 fix for #2300. The code doesn't use SSL and a test requires it.
Carlos Martín Nieto 783555d8 2014-04-26T14:36:32 netops: catch the server not sending a certificate It's possible for an encrypted connection not have a certificate. In this case, SSL_get_verify_result() will return OK because no error happened (as it never even tried to validate anything). SSL_get_peer_certificate() will return NULL in this case so we need to catch that. On the upside, the current code would segfault in this situation instead of letting it through as a valid cert.
Carlos Martín Nieto 51d3f6f5 2014-04-26T14:16:42 netops: provide more specific error for cert failure Specify what we do not like about the certificate. In this case, we do not like the name.
Carlos Martín Nieto 1f0d4f3d 2014-04-26T13:51:14 netops: unit-test the cert host-name pattern matching This kind of stuff should have unit tests, even if it's just to show what we expect to match successfully.

Ben Straub 8988688c 2013-09-25T20:41:56 Migrate redirect URL handling to common utility
Russell Belfer eb0ff130 2013-09-24T14:07:08 Disconnect path string to preserve after redirect The subtransport path was relying on pointing to data owned by the remote which meant that after a redirect, the updated path was getting lost for future requests. This updates the http transport to strdup the path and maintain its own lifetime. This also pulls responsibility for parsing the URL back into the http transport and isolates the functions that parse and free that connection data so that they can be reused between the initial parsing and the redirect parsing.

Michael Schubert f2b00cbd 2012-12-17T19:35:40 netops: on SSL teardown only send shutdown alert According to man 3 SSL_shutdown / TLS, "If a unidirectional shutdown is enough (the underlying connection shall be closed anyway), this first call to SSL_shutdown() is sufficient." Currently, an unidirectional shutdown is enough, since gitno_ssl_teardown is called by gitno_close only. Do so to avoid further errors (by misbehaving peers for example). Fixes #1129.
Michael Schubert 9c8dbc88 2012-12-17T19:18:34 netops: properly handle GITNO_CONNECT_SSL_NO_CHECK_CERT Don't return an error just because GITNO_CONNECT_SSL_NO_CHECK_CERT is set.
Fraser Tweedale 9e9aee67 2012-11-26T23:29:34 fix build on FreeBSD 3f9eb1e introduced support for SSL certificates issued for IP addresses, making use of in_addr and in_addr6 structs. On FreeBSD these are defined in (a file included in) <netinet/in.h>, so include that file on FreeBSD and get the build working again.

Michael Schubert 65ac67fb 2012-08-28T21:58:10 netops: be more careful with SSL errors SSL_get_error() allows to receive a result code for various SSL operations. Depending on the return value (see man (3) SSL_get_error) there might be additional information in the OpenSSL error queue. Return the queued message if available, otherwise set an error message corresponding to the return code.
Michael Schubert 4deda91b 2012-09-04T00:13:59 netops: continue writing on SSL_ERROR_WANT_WRITE
Carlos Martín Nieto 0d5dce26 2012-08-28T14:15:32 ssl: make cert check ignore work for invalid certs, not just CNs Passing SSL_VERIFY_PEER makes OpenSSL shut down the connection if the certificate is invalid, without giving us a chance to ignore that error. Pass SSL_VERIFY_NONE and call SSL_get_verify_result if the user wanted us to check. When no CNs match, we used to jump to on_error which gave a bogus error as that's for OpenSSL errors. Jump to cert_fail so we tell the user that the error came from checking the certificate.

Carlos Martín Nieto 0048372a 2012-07-27T01:09:06 transport: rename encrypt to use_ssl SSL isn't the only way that a transport can be encrypted. The new name will make it easier to merge the SSH support.
Carlos Martín Nieto 8861d32f 2012-07-25T16:16:53 ssl: use the callback instead of ifs to determine how to get data Using the callbacks makes it clearer and reduces the amount of #ifdefs and ifs and we need in the code.
Carlos Martín Nieto b49c8f71 2012-07-24T19:03:22 remote: use the same code to control git and http This allows us to add capabilitites to both at the same time, keeps them in sync and removes a lot of code. gitno_buffer now uses a callback to fill its buffer, allowing us to use the same interface for git and http (which uses callbacks).

Scott J. Goldman 901fbdad 2012-05-07T00:05:02 Define explicit _WIN32_WINNT version in makefile Previously, it was defined in netops.c, but it's also needed in one of the clar tests, so I figured we might as well just make it global for the whole project. Without it, the mingw32 linker won't resolve GetProcessId() (called from the core/errors.c clar test) because of some conditionals in windows.h.

Scott J. Goldman b4b96d56 2012-05-05T13:30:33 Fix gitno_connect() error handling on Windows gitno_connect() can return an error or socket, which is fine on most platforms where sockets are file descriptors (signed int), but on Windows, SOCKET is an unsigned type, which is problematic when we are trying to test if the socket was actually a negative error code. This fix seperates the error code and socket in gitno_connect(), and fixes the error handling in do_connect() functions to compensate. It appears that git_connect() and the git-transport do_connect() functions had bugs in the non-windows cases too (leaking sockets, and not properly reporting connection error, respectively) so I went ahead and fixed those too.
