2018-04-03Enable specific ioctl call for EP11 crypto card (s390)Eduardo Barretto
The EP11 crypto card needs to make an ioctl call, which receives an specific argument. This crypto card is for s390 only.

2018-04-03Allow getuid and geteuid callsEduardo Barretto
getuid and geteuid are needed when using an openssl engine that calls a crypto card, e.g. ICA (libica). Those syscalls are also needed by the distros for audit code.

2018-04-03Allow flock and ipc syscall for s390 architectureEduardo Barretto
In order to use the OpenSSL-ibmpkcs11 engine it is needed to allow flock and ipc calls, because this engine calls OpenCryptoki (a PKCS#11 implementation) which calls the libraries that will communicate with the crypto cards. OpenCryptoki makes use of flock and ipc and, as of now, this is only need on s390 architecture.

2018-04-03Don't check the status field of the OpenSSL versionKurt Roeckx
There is no reason to check the version of OpenSSL (in Debian). If it's not compatible the soname will change. OpenSSH seems to want to do a check for the soname based on the version number, but wants to keep the status of the release the same. Remove that check on the status since it doesn't tell you anything about how compatible that version is.

This makes it easier to audit networks for versions patched against security vulnerabilities.

2018-04-03Allow harmless group-writabilityColin Watson
Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be group-writable, provided that the group in question contains only the file's owner. Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding about the contents of gr->gr_mem). Given that per-user groups and umask 002 are the default setup in Debian (for good reasons - this makes operating in setgid directories with other groups much easier), we need to permit this by default.

2018-04-03"LogLevel SILENT" compatibilityJonathan David Amery
"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to match the behaviour of non-free SSH, in which -q does not suppress fatal errors. However, this was unintentionally broken in 1:4.6p1-2 and nobody complained, so we've dropped most of it. The parts that remain are basic configuration file compatibility, and an adjustment to "Pseudo-terminal will not be allocated ..." which should be split out into a separate patch.

2018-04-03Various keepalive extensionsRichard Kettlewell
Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported in previous versions of Debian's OpenSSH package but since superseded by ServerAliveInterval. (We're probably stuck with this bit for compatibility.) In batch mode, default ServerAliveInterval to five minutes. Adjust documentation to match and to give some more advice on use of keepalives.

These options were used as part of Debian's response to CVE-2008-0166. Nearly six years later, we no longer need to continue carrying the bulk of that patch, but we do need to avoid failing when the associated configuration options are still present.

2018-04-03Handle SELinux authorisation rolesManoj Srivastava
Rejected upstream due to discomfort with magic usernames; a better approach will need an SSH protocol change. In the meantime, this came from Debian's SELinux maintainer, so we'll keep it until we have something better.

2018-04-03Restore TCP wrappers supportColin Watson
Support for TCP wrappers was dropped in OpenSSH 6.7. See this message and thread: https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html It is true that this reduces preauth attack surface in sshd. On the other hand, this support seems to be quite widely used, and abruptly dropping it (from the perspective of users who don't read openssh-unix-dev) could easily cause more serious problems in practice. It's not entirely clear what the right long-term answer for Debian is, but it at least probably doesn't involve dropping this feature shortly before a freeze. Forwarded: not-needed Last-Update: 2014-10-07 Patch-Name: restore-tcp-wrappers.patch
2018-04-03GSSAPI key exchange supportSimon Wilkinson
This patch has been rejected upstream: "None of the OpenSSH developers are in favour of adding this, and this situation has not changed for several years. This is not a slight on Simon's patch, which is of fine quality, but just that a) we don't trust GSSAPI implementations that much and b) we don't like adding new KEX since they are pre-auth attack surface. This one is particularly scary, since it requires hooks out to typically root-owned system resources." However, quite a lot of people rely on this in Debian, and it's better to have it merged into the main openssh package rather than having separate -krb5 packages (as we used to have). It seems to have a generally good security history. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1242 Last-Updated: 2017-10-04 Patch-Name: gssapi.patch

2018-03-30Disable native strndup and strnlen on AIX.Darren Tucker
On at least some revisions of AIX, strndup returns unterminated strings under some conditions, apparently because strnlen returns incorrect values in those cases. Disable both on AIX and use the replacements from openbsd-compat. Fixes problem with ECDSA keys there, ok djm.
2018-03-26Include ssh_api.h for struct ssh.Darren Tucker
struct ssh is needed by implementations of sys_auth_passwd() that were converted in commit bba02a50. Needed to fix build on AIX, I assume for the other platforms too (although it should be harmless if not needed).
