2016-05-24Fix handling of integer wraparound in megolm.cRichard van der Hoff
2016-05-24megolm_advance_to: Remove excessive optimisationRichard van der Hoff
There was some slightly overcomplex logic designed to save a couple of hash operations when R(0) and R(1) were advanced, but the extra code was hard to understand and didn't save much.
2016-05-24megolm.c: rewrite counter updateRichard van der Hoff
We no longer need to keep track of intermediate values of the counter, which means we can update it much more easily.
2016-05-24megolm.c: Remove spurious arguments to rehash_partRichard van der Hoff
These were left over from when rehash_part did a bunch of logging.
2016-05-24Separate base64ing from the rest of msg encodingRichard van der Hoff
Factor the actual message encoding/decoding and encrypting/decrypting out to separate functions from the top-level functions which do the base64-wrangling. This is particularly helpful in the 'outbound' code-path where the offsets required to allow room to base64-encode make the flow hard to see when it's all inline.
2016-05-24Update megolm_cipher as a global structRichard van der Hoff
Initialise megolm_cipher via the preprocessor macro, instead of with a function.
2016-05-24Use _olm_unset instead of memsetRichard van der Hoff
memset is at risk of being optimised away, so use _olm_unset instead.
2016-05-24Avoid relying on uint -> int casting behaviourRichard van der Hoff
The behaviour when casting from a uint32_t which has overflowed (so has the top bit set) to int32_t is implementation-defined, so let's avoid relying on it.
2016-05-24Python wrapper: support for inbound group sessionsRichard van der Hoff
2016-05-24Fix up some names, and protobuf tagsRichard van der Hoff
Make names (of session_key and message_index) more consistent. Use our own protobuf tags rather than trying to piggyback on the one-to-one structure.
2016-05-24Support for pickling inbound group sessionsRichard van der Hoff
2016-05-24Implement decrypting inbound group messagesRichard van der Hoff
Includes creation of inbound sessions, etc
2016-05-24Implement functions to get the state of outbound sessionRichard van der Hoff
We need to be able to inspect an outbound session so that we can tell our peer how to set up an inbound session.
2016-05-24Outbound group session support in the python wrappersRichard van der Hoff
2016-05-24Implement pickling/unpickling for outbound group sessionsRichard van der Hoff
2016-05-24Implementation of an outbound group sessionRichard van der Hoff
2016-05-24Implementation of the megolm ratchetRichard van der Hoff
2016-05-24Factor out pickle_encoding from olm.cppRichard van der Hoff
We don't need to have all of the top-level pickling functions in olm.cpp; factor out the utilities to support it to pickle_encoding.cpp (and make sure that they have plain-C bindings).
2016-05-24Factor out olm_error_to_string to a separate fileRichard van der Hoff
I want to be able to use this functionality from elsewhere, so factor it out to its own file.
2016-05-24Merge branch 'rav/c_bindings'Richard van der Hoff
2016-05-24Rewrite _olm_cipher_aes_sha_256 initialisationRichard van der Hoff
Replace the init-static-var dance with some preprocessor macros
2016-05-24Remove 'destruct' from cipher_opsRichard van der Hoff
We never delete a cipher, and the destruct op is empty, so it's a bit pointless
2016-05-23Fix bug in bounds check when parsingMark Haines
2016-05-23Prefix for internal symbolsRichard van der Hoff
Give a load of internal symbols "_olm_" prefixes. This better delineates the public and private interfaces in the module, and helps avoid internal symbols leaking out and possibly being abused.
2016-05-23C bindings for base64 functionsRichard van der Hoff
2016-05-23C binding for olm::unsetRichard van der Hoff
2016-05-23C bindings for pickle functionsRichard van der Hoff
2016-05-23Convert cipher.hh to plain CRichard van der Hoff
2016-05-23Convert error.hh to plain CRichard van der Hoff
2016-05-23Give SHA256 functions C bindingsRichard van der Hoff
2016-05-23Rename olm.hh to olm.hRichard van der Hoff
2016-05-23Complete fixes for olm_*_last_errorRichard van der Hoff
Should have been in the previous commit :/
2016-05-23fix range check in olm_*_last_errrorRichard van der Hoff
2016-05-23Fix warnings and set -WerrorRichard van der Hoff
2016-05-23Merge branch 'rav/refactor_python_wrappers'Richard van der Hoff
2016-05-23Fix make clean to remove the library and all the .d filesMark Haines
2016-05-23Move comment to correct locationMark Haines
2016-05-23Don't use $^ cause that includes the header filesMark Haines
2016-05-23Use a rule to make the build directoriesMark Haines
2016-05-23Put the .o files in separate directories so we can have both release and ↵Mark Haines
debug versions
2016-05-20Fix the Makefile so that it works with a clean git checkoutMark Haines
2016-05-20Merge branch 'rav/makefile'Richard van der Hoff
2016-05-20Remove dep files for js objects on cleanRichard van der Hoff
2016-05-20crypto.cpp: Fix commentsRichard van der Hoff
These seem to be the wrong way around.
2016-05-20Add an 'all' target to the MakefileRichard van der Hoff
So that we can build everything together.
2016-05-20Refactor python wrappersRichard van der Hoff
Split the python wrappers into separate modules
2016-05-20Use a version script to restrict symbols in the .soRichard van der Hoff
We want to stop aes_* and sha_* functions leaking out of our .so, as well as internal _olm_* symbols. This also means we need to link the unit tests against the objects. Possibly we should distinguish between unit tests and integration tests.
2016-05-20Add support for building the JS wrappers to the MakefileRichard van der Hoff
Now that we have C and C++, we need to split the compile and link steps (because we need different flags for the C and C++ files), so this is easier with a Makefile.
2016-05-20Add a makefileRichard van der Hoff
Replace the python scripts for building the shared lib and tests with a Makefile, which makes it easier to handle a mix of C and C++.
2016-05-20Remove functions which return stringsRichard van der Hoff
We don't want anything which does dynamic memory allocation in the library.
