* Remove support for snappy compression.Gert Doering2015-10-111-1/+1
| | | | | | | | | | | | | | | | | LZ4 is using less CPU at similar performance, and it is easier to build and support for binary installs (as it does not require C++ and a C++ runtime). Since it was never supported in any formally released OpenVPN version, just drop it again. This leaves in the compression opcode for Snappy for documentation purposes. trac #617 Signed-off-by: Gert Doering <gert@greenie.muc.de> Acked-by: Arne Schwabe <arne@rfc2549.org> Message-Id: <1444494889-28925-1-git-send-email-gert@greenie.muc.de> URL: http://article.gmane.org/gmane.network.openvpn.devel/10251

* get_default_gateway_ipv6(): Win32 implementation using GetBestRoute2()Gert Doering2015-10-061-1/+6
| | | | | | | | | | | | | | | | | | | | | | | To get access to that functionality, bump Windows API level for MinGW compilation from NTDDI_WINXP/_WIN32_WINNT_WINXP to ..._VISTA, and shuffle around WIN32 includes a bit in syshead.h MinGW 32 seems to be broken regarding MIB_TCP_STATE enum, so add typedef for that - surrounding #ifdefs found by googling do not work yet -> TODO! Extend add_route_ipv6() and delete_route_ipv6() to handle routes not on the tap adapter but on ifindex-addressed interfaces ("interface=nn"), and while at it, fix deletion of IPv6 routes with gateway address. NOTE: this breaks Windows XP compatibility as GetBestRoute2() is not available there, so even when not using IPv6, the binary will not run. (Lightly) tested on Win7/64.

* Remove ENABLE_SSL define (and --disable-ssl configure option)Steffan Karger2014-12-311-5/+5
| | | | | | | | | | | | | | | | | | | Remove the --disable-ssl configure option and accompanying ENABLE_SSL defines in the master/2.4 branch, to reduce the code and testing complexity a bit. This does not remove to runtime option to run without SSL, just the compile time option to not include any SSL-related code. During the community meeting in November 2014 there were no objections amongst he developers present. Also, this has been announced on the -users and -devel mailing lists two weeks ago, without any response whatsoever.

* Implement LZ4 compression.Gert Doering2014-01-061-1/+2
| | | | | | | | | | | | | | | | | | Implement LZ4 compression, similar to the existing snappy / push-peer-info model: a LZ4 capable client will send IV_LZ4=1 to the server, and the algorithm is selected by pushing "compress lz4" back. LZ4 does not compress as well as LZO or Snappy, but needs far less CPU and is much faster, thus better suited for mobile devices. See https://code.google.com/p/lz4/ for more details. LZ4 include and library path can be specified by specifying LZ4_LIBS=... and LZ4_CFLAGS=... on the configure command line.

* Added support for the Snappy compression algorithmJames Yonan2013-05-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added support for the Snappy compression algorithm which has shown to have considerably better compression speed than LZO at a comparable compression ratio. To enable Snappy add: compress snappy to both client and server config files. Alternatively, enable compression framing on the client: compress and have the server selectively push "compress snappy" to the client. This change also extends the client capability handshake to include IV_SNAPPY so the server can be aware that a connecting client supports Snappy. Note that the Snappy implementation also includes an improved framing approach where the first byte of the compressed payload is replaced by the compression control byte (the first payload byte is moved to the end of the packet). This solves off-by-one alignment issues, which improves performance on ARM. By default, the configure script will try to build with Snappy support. To disable, use the --disable-snappy option. The --enable-lzo-stub configure directive is now --enable-comp-stub (because it's not actually "lzo" but "compression-enabled packet framing") Add compression overhead to extra buffer unconditionally, as long as USE_COMP is defined.

| | | | | | | | | | | | | | | | | | PolarSSL 1.0 and earlier use only the Havege RNG. Havege is based on timing certain operations, using the RDTSC instruction. Although this is fine on bare metal PCs, the RDTSC instruction is virtualised on some virtual machine implementations. This can result in issues on those virtual machines. PolarSSL fixes this potential issue by also using platform entropy. To ensure that OpenVPN is always built against a decent RNG, PolarSSL <1.1 is therefore no longer supported.
