* Remove support for snappy compression.Gert Doering2015-10-111-3/+0
| | | | | | | | | | | | | | | | | 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
* systemd: Use systemd functions to consider systemd availabilityDavid Sommerseth2014-10-071-0/+1
| | | | | | | | | | | | | | | | | | | | | This is another systemd implementation clean-up. It was found that SELinux will block OpenVPN from checking /sys/fs/cgroups. As OpenVPN only checked /sys/fs/cgroups and /sys/fs/cgroups/systemd to see if systemd was available or not, it was considered better to query systemd directly to see whether or not to query for usernames and passwords via systemd. This patch has been compile tested on Fedora 19 and Fedora 21 alpha and function tested on Fedora 19. v2 - Use PKG_CHECK_MODULES() + check for libsystemd before libystemd-daemon. systemd >= 209 use a unified library Signed-off-by: David Sommerseth <davids@redhat.com> Acked-by: Gert Doering <gert@greenie.muc.de> Message-Id: <1412356567-27125-1-git-send-email-openvpn.list@topphemmelig.net> URL: http://article.gmane.org/gmane.network.openvpn.devel/9072 Signed-off-by: Gert Doering <gert@greenie.muc.de>

* Implement LZ4 compression.Gert Doering2014-01-061-0/+3
| | | | | | | | | | | | | | | | | | 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/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
