Author: bdrewery Date: Sat Apr 4 17:16:58 2015 New Revision: 383231 URL: https://svnweb.freebsd.org/changeset/ports/383231 Log: - Update to 6.8p1 - Fix 'make test' - HPN: - NONECIPHER is no longer default. This is not default in base and should not be default here as it introduces security holes. - HPN: I've audited the patch and included it in the port directory for transparency. I identified several bugs and submitted them to the new upstream: https://github.com/rapier1/openssh-portable/pull/2 - HPN: The entire patch is now ifdef'd to ensure various bits are properly removed depending on the OPTIONS selected. - AES_THREADED is removed. It has questionable benefit on modern HW and is not stable. - The "enhanced logging" was removed from the patch as it is too intrusive and difficult to maintain in the port. - The progress meter "peak throughput" patch was removed. - Fixed HPN version showing in client/server version string when HPN was disabled in the config. - KERB_GSSAPI is currently BROKEN as it does not apply. - Update X509 to 8.3 Changelog: http://www.openssh.com/txt/release-6.8 Added: head/security/openssh-portable/files/extra-patch-hpn (contents, props changed) head/security/openssh-portable/files/patch-regress__test-exec.sh (contents, props changed) head/security/openssh-portable/files/patch-sshconnect.c (contents, props changed) Deleted: head/security/openssh-portable/files/extra-patch-hpn-build-options head/security/openssh-portable/files/extra-patch-hpn-no-hpn head/security/openssh-portable/files/extra-patch-hpn-window-size Modified: head/security/openssh-portable/Makefile head/security/openssh-portable/distinfo head/security/openssh-portable/files/extra-patch-sshd-utmp-size head/security/openssh-portable/files/extra-patch-tcpwrappers head/security/openssh-portable/files/patch-servconf.c head/security/openssh-portable/files/patch-ssh-agent.c Modified: head/security/openssh-portable/Makefile ============================================================================== --- head/security/openssh-portable/Makefile Sat Apr 4 16:23:55 2015 (r383230) +++ head/security/openssh-portable/Makefile Sat Apr 4 17:16:58 2015 (r383231) @@ -2,8 +2,8 @@ # $FreeBSD$ PORTNAME= openssh -DISTVERSION= 6.7p1 -PORTREVISION= 5 +DISTVERSION= 6.8p1 +PORTREVISION= 0 PORTEPOCH= 1 CATEGORIES= security ipv6 MASTER_SITES= ${MASTER_SITE_OPENBSD} @@ -27,13 +27,10 @@ CONFIGURE_ARGS= --prefix=${PREFIX} --wi --without-zlib-version-check --with-ssl-engine ETCOLD= ${PREFIX}/etc -SUDO?= # empty -MAKE_ENV+= SUDO="${SUDO}" -

This will allow ssh installations ++on hosts with multiple cores to use more than one processing core during encryption. ++Tests have show significant throughput performance increases when using MTR-AES-CTR up ++to and including a full gigabit per second on quad core systems. It should be possible to ++achieve full line rate on dual core systems but OS and data management overhead makes this ++more difficult to achieve. The cipher stream from MTR-AES-CTR is entirely compatible with single ++thread AES-CTR (ST-AES-CTR) implementations and should be 100% backward compatible. Optimal ++performance requires the MTR-AES-CTR mode be enabled on both ends of the connection. ++The MTR-AES-CTR replaces ST-AES-CTR and is used in exactly the same way with the same ++nomenclature. ++Use examples: ssh -caes128-ctr you@host.com ++ scp -oCipher=aes256-ctr file you@host.com:~/file ++ ++NONE CIPHER: ++To use the NONE option you must have the NoneEnabled switch set on the server and ++you *must* have *both* NoneEnabled and NoneSwitch set to yes on the client. The NONE ++feature works with ALL ssh subsystems (as far as we can tell) *AS LONG AS* a tty is not ++spawned. If a user uses the -T switch to prevent a tty being created the NONE cipher will ++be disabled. ++ ++The performance increase will only be as good as the network and TCP stack tuning ++on the reciever side of the connection allows. As a rule of thumb a user will need ++at least 10Mb/s connection with a 100ms RTT to see a doubling of performance. The ++HPN-SSH home page describes this in greater detail. ++ ++http://www.psc.edu/networking/projects/hpn-ssh ++ ++BUFFER SIZES: ++ ++If HPN is disabled the receive buffer size will be set to the ++OpenSSH default of 64K. ++ ++If an HPN system connects to a nonHPN system the receive buffer will ++be set to the HPNBufferSize value. The default is 2MB but user adjustable. ++ ++If an HPN to HPN connection is established a number of different things might ++happen based on the user options and conditions. ++ ++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set ++HPN Buffer Size = up to 64MB ++This is the default state. The HPN buffer size will grow to a maximum of 64MB ++as the TCP receive buffer grows. The maximum HPN Buffer size of 64MB is ++geared towards 10GigE transcontinental connections. ++ ++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set ++HPN Buffer Size = TCP receive buffer value. ++Users on non-autotuning systesm should disable TCPRcvBufPoll in the ++ssh_cofig and sshd_config ++ ++Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set ++HPN Buffer Size = minmum of TCP receive buffer and HPNBufferSize. ++This would be the system defined TCP receive buffer (RWIN). ++ ++Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf SET ++HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize. ++Generally there is no need to set both. ++ ++Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set ++HPN Buffer Size = grows to HPNBufferSize ++The buffer will grow up to the maximum size specified here. ++ ++Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf SET ++HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize. ++Generally there is no need to set both of these, especially on autotuning ++systems. However, if the users wishes to override the autotuning this would be ++one way to do it. ++ ++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf SET ++HPN Buffer Size = TCPRcvBuf. ++This will override autotuning and set the TCP recieve buffer to the user defined ++value. ++ ++ ++HPN Specific Configuration options ++ ++TcpRcvBuf=[int]KB client ++ set the TCP socket receive buffer to n Kilobytes. It can be set up to the ++maximum socket size allowed by the system. This is useful in situations where ++the tcp receive window is set low but the maximum buffer size is set ++higher (as is typical). This works on a per TCP connection basis. You can also ++use this to artifically limit the transfer rate of the connection. In these ++cases the throughput will be no more than n/RTT. The minimum buffer size is 1KB. ++Default is the current system wide tcp receive buffer size. ++ ++TcpRcvBufPoll=[yes/no] client/server ++ enable of disable the polling of the tcp receive buffer through the life ++of the connection. You would want to make sure that this option is enabled ++for systems making use of autotuning kernels (linux 2.4.24+, 2.6, MS Vista) ++default is yes. ++ ++NoneEnabled=[yes/no] client/server ++ enable or disable the use of the None cipher. Care must always be used ++when enabling this as it will allow users to send data in the clear. However, ++it is important to note that authentication information remains encrypted ++even if this option is enabled. Set to no by default. ++ ++NoneSwitch=[yes/no] client ++ Switch the encryption cipher being used to the None cipher after ++authentication takes place. NoneEnabled must be enabled on both the client ++and server side of the connection. When the connection switches to the NONE ++cipher a warning is sent to STDERR. The connection attempt will fail with an ++error if a client requests a NoneSwitch from the server that does not explicitly ++have NoneEnabled set to yes. Note: The NONE cipher cannot be used in ++interactive (shell) sessions and it will fail silently. Set to no by default. ++ ++HPNDisabled=[yes/no] client/server ++ In some situations, such as transfers on a local area network, the impact ++of the HPN code produces a net decrease in performance. In these cases it is ++helpful to disable the HPN functionality. By default HPNDisabled is set to no. ++ ++HPNBufferSize=[int]KB client/server ++ This is the default buffer size the HPN functionality uses when interacting ++with nonHPN SSH installations. Conceptually this is similar to the TcpRcvBuf ++option as applied to the internal SSH flow control. This value can range from ++1KB to 64MB (1-65536). Use of oversized or undersized buffers can cause performance ++problems depending on the length of the network path. The default size of this buffer ++is 2MB. ++ ++ ++Credits: This patch was conceived, designed, and led by Chris Rapier (rapier@psc.edu) ++ The majority of the actual coding for versions up to HPN12v1 was performed ++ by Michael Stevens (mstevens@andrew.cmu.edu).
