2016-04-05Migrate to Boost.Signals2 from Boost.SignalsTobias Markmann
Boost.Signals was deprecated and is not improved further. This patch removes Boost.Signals from 3rdParty and adds Boost.Signals2 and its dependencies. Also removed the Qt signals compatibility file Swiften/Base/boost_bsignals.h. Test-Information: Build and ran unit tests on OS X 10.11.4. Confirmed successful login using Swift client. Change-Id: Ie6e3b2d15aac2462cda95401582f5287a479fb54
2016-04-04Modernize code to use C++11 shared_ptr instead of Boost'sTobias Markmann
This change was done by applying the following 'gsed' replacement calls to all source files: 's/\#include <boost\/shared_ptr\.hpp>/\#include <memory>/g' 's/\#include <boost\/enable_shared_from_this\.hpp>/\#include <memory>/g' 's/\#include <boost\/smart_ptr\/make_shared\.hpp>/\#include <memory>/g' 's/\#include <boost\/make_shared\.hpp>/\#include <memory>/g' 's/\#include <boost\/weak_ptr\.hpp>/\#include <memory>/g' 's/boost::make_shared/std::make_shared/g' 's/boost::dynamic_pointer_cast/std::dynamic_pointer_cast/g' 's/boost::shared_ptr/std::shared_ptr/g' 's/boost::weak_ptr/std::weak_ptr/g' 's/boost::enable_shared_from_this/std::enable_shared_from_this/g' The remaining issues have been fixed manually. Test-Information: Code builds on OS X 10.11.4 and unit tests pass. Change-Id: Ia7ae34eab869fb9ad6387a1348426b71ae4acd5f
2016-04-01Modernize code to use C++11 nullptr using clang-tidyTobias Markmann
Run 'clang-tidy -fix -checks=modernize-use-nullptr' on all source code files on OS X. This does not modernize platform specific code on Linux and Windows Test-Information: Code builds and unit tests pass on OS X 10.11.4. Change-Id: Ic43ffeb1b76c1a933a55af03db3c54977f5f60dd
2016-03-31Convert tabs to 4 spaces for all source filesTobias Markmann
Removed trailing spaces and whitespace on empty lines in the process. Changed CheckTabs.py tool to disallow hard tabs in source files. Test-Information: Manually checked 30 random files that the conversion worked as expected. Change-Id: I874f99d617bd3d2bb55f02d58f22f58f9b094480
2016-03-31Stop building some TLS providers as always staticKevin Smith
Thanks to Manfred Urban for reporting that dynamic libraries weren't working. Test-Information: Swiften Builds on OS X with swiften_dll=True Change-Id: I31e40ac118b9be6b43803a2bbcbfef3a9f9f9d21
2016-03-30Apply consistent #include grouping and sorting styleTobias Markmann
Changed "" style includes to <> style. Test-Information: Build with Clang 3.9.0 and ran all tests on OS X 10.11.4. Change-Id: Ic05e53f2e5dba39cc1307b116fc5f17b62ab9eb8
2016-03-15Explicitly convert between nullable and non-nullable on OS XTobias Markmann
Clang was complaining about implicit conversions between nullable and non-nullable NSString pointers. Adjusted our std::string -> NSString* conversion utilities to check for nil and return an empty std::string in that case. Replaced uses of [NSString stringWithUTF8String] with our STD2NSSTRING macro. Turned std::string <-> NSString* conversion macros into functions. Test-Information: Builds without the warning on OS X 10.11.3 and Swift runs without issues. Change-Id: I949f2f3332018391aead58ef362764f4b7955b01
2016-02-08Fix and adjust TLSTest to Windows SChannel backendTobias Markmann
Test-Information: ./scons test=system Swiften/QA/TLSTest passes on Windows 8. Change-Id: I688ec5d0022c02879ff56029d724e6dd30b89a99
2016-02-08Treat cert verify errors as non-fatal in OS X TLS backendTobias Markmann
Our TLS backends need to tread TLS verification errors, e.g. outdated certificate, untrusted CA, non-matching host, etc., as non-fatal, so the application can apply custom key pinning verification or similar. This patch changes the OS X SecureTransport backend to behave accordingly and adjusts the CertificateErrorTest to mirror this behavior. This commit also fixes a double-free in SecureTransportCertificate. Test-Information: Connected to a host with an untrusted CA and non-matching domain in the certificate and was prompted with the Swift certificate trust dialog on OS X 10.11.3. Swiften/QA/TLSTest run successfully on OS X 10.11.3. Change-Id: I4c8ce2178540d79a5f328e2e0558d4deb4295134
2016-02-01Disable certificate revocation checking in OS X TLS backendTobias Markmann
Default to disabled certificate revocation checking for SecureTransport TLS backend on OS X. SecureTransport internal revocation checking machine is not very stable and sometimes fails reporting a positive revocation check leading to bad UX. Test-Information: Swift login still works and ./scons test=system pass on OS X 10.11.3. Change-Id: I298ccca4ecab07af5517fe393fdb887d79d70bf1
2015-11-10Fix Cocoa memory management error in Secure Transport backendTobias Markmann
The code was calling CFRelease on a null pointer, which runs into an assert inside CFRelease. Test-Information: The crash happened during client certificate authentication using the Secure Transport backend. With this patch the crash is gone. Change-Id: If389dcb8b8a20fdc5cf77219d6c5afb86c9c3634
2015-11-06Fix potential memory leaks in Cocoa API usageTobias Markmann
These errors were reported by Clang Analyzer. Test-Information: Verified that behavior is still as expected and Clang Analyzer does not report the warnings anymore. Change-Id: I149d75241f7680a6d2f2b6b710dd38d1ed81a209
2015-10-30Add support for OS X Secure Transport TLS backendTobias Markmann
Added integration tests for certificate validation and revocation behavior checking. Test-Information: Tested client login over TLS against Prosody and M-Link. Verified client certificate authentication works against M-Link. Change-Id: I6ad870f17adbf279f3bac913a3076909308a0021
2015-09-22Add explicit includes for classes used in PlatformTLSFactoriesTobias Markmann
Furthermore removed unneeded includes. Test-Information: Still builds and unit tests pass. Change-Id: Ic7272e754c488f427b5ee6834f1d892028ea285d
2015-07-07Add hidden option to prevent disconnect when smartcard removedMili Verma
This patch adds an option 'disconnectOnCardRemoval' to system-settings.xml which when set to false allows the user's session to stay connected if the smartcard is removed. The default value of this option is true if it is not specified. Test-information: Tested on Windows using NIST smartcards. Tested true and false values set for this option in the file and also when option is not specified (true). Unit tests pass. Change-Id: I7e421b4153ff7d3000f41999add20d339076c96e
2015-07-02Reestablish connection with smart cardMili Verma
When the card is reset in shared mode (which is the mode we use), an application trying to access certain commands will be returned the value SCARD_W_RESET_CARD. When this occurs SCardReconnect() must be called. This wasn't done before so this patch fixes it. Also provides more logging for SCard function returns. Test-information: Tested on Windows using NIST smart cards. Before the fix, the Card Removed Error was seen often even after the initial connection was established. After the fix, the reconnect attempt is done so the error is not seen. Also verified that if a card is removed deliberately, then the user is logged out. Change-Id: I94748ab9ff944a79de655646e1e06a8b61776f4b
2015-06-10Add ability to limit SChannel to TLS 1.0Kevin Smith
Some servers have very restrictive TLS stacks that respond badly to a bug in the SChannel TLS implementation, meaning that TLS has to be limited to 1.0. Add ClientOptions.tlsOptions. This is a method of passing options into the TLS stack. It's currently only used for the TLS 1.0 workaround in SChannel, but we might reasonably expose other options in the future, such as limiting cypher suites. Disables use of SSLv3 for SChannel Also updates the coding style in SchannelContext a bit. Test-Information: Compiles on both OS X and Windows(SChannel). OS X doesn't show the new option. Windows shows it, and remembers it between logins. Not tested against a server requiring 1.0 only, but a previous hack with the same approach was tested. Change-Id: I1e7854d43811fd173f21f98d4dc3915fc7a4b322

2013-09-23Don't crash if server doesn't send cert in TLS handshakeNick Hudson
This patch reflects a change to Stroke, which is described as follows: If a TLS connection results in the server choosing an anonymous cipher suite, then no server certificate will be returned by the server. This ought not to happen, since XMPP clients are expected only to propose non-anonymous cipher suites, but it could be that a client is coded to propose anonymous suites, or that a bug in the server means that it fails to return a server certificate. This change updates the ServerIdentityVerifier to make it resilient against these situations, treating this situation as equivalent to "certificate presented by server does not verify". Test-information: Tested in Stroke. Untested in Swiften Change-Id: Iec815b09b6be675edad1d479d1a0a9d6b0b91bf3
2013-05-17Fixed unicode path handling.Remko Tronçon
- Use boost::filesystem::path consistently for referring to files. - Use boost::filesystem streams for I/O, such that paths are always handled correctly. - Use stringToPath and pathToString for conversion between strings and boost::filesystem::path, to ensure we have consistent unicode handling across platforms and environments. The default constructor and string conversion uses platform-dependent encoding, depending on the global locale set in the application, which causes problems. So, unless you are in platform dependent code, the default constructor and string() function should not be used. When constructing paths from other paths (e.g. using operator/), also use stringToPath (instead of string arguments) if the path can contain unicode characters.
