2019-10-05Deny (non-fatal) shmget/shmat/shmdt in preauth privsep child.Lonnie Abelbeck
New wait_random_seeded() function on OpenSSL 1.1.1d uses shmget, shmat, and shmdt in the preauth codepath, deny (non-fatal) in seccomp_filter sandbox. Bug: https://github.com/openssh/openssh-portable/pull/149 Bug-Debian: https://bugs.debian.org/941663 Origin: upstream, https://anongit.mindrot.org/openssh.git/commit/?id=3ef92a657444f172b61f92d5da66d94fa8265602 Last-Update: 2019-10-05 Patch-Name: seccomp-handle-shm.patch
2019-06-21Update utimensat test.Darren Tucker
POSIX specifies that when given a symlink, AT_SYMLINK_NOFOLLOW should update the symlink and not the destination. The compat code doesn't have a way to do this, so where possible it fails instead of following a symlink when explicitly asked not to. Instead of checking for an explicit failure, check that it does not update the destination, which both the real and compat implementations should honour. Inspired by github pull req #125 from chutzpah at gentoo.org. Origin: upstream, https://anongit.mindrot.org/openssh.git/commit/?id=182898192d4b720e4faeafd5b39c2cfb3b92aa21 Last-Update: 2019-06-09 Patch-Name: fix-utimensat-test.patch
2019-06-21Revert "upstream: Update default IPQoS in ssh(1), sshd(8) to DSCP AF21 for"Colin Watson
This reverts commit 5ee8448ad7c306f05a9f56769f95336a8269f379. The IPQoS default changes have some unfortunate interactions with iptables (see https://bugs.debian.org/923880) and VMware, so I'm temporarily reverting them until those have been fixed.

2019-06-21Fix interop tests for recent regress changesColin Watson
A recent regress change (2a9b3a2ce411d16cda9c79ab713c55f65b0ec257 in portable) broke the PuTTY and Twisted Conch interop tests, because the key they want to use is now called ssh-rsa rather than rsa.

2019-06-21Enable 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.

2019-06-21Allow 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.

2019-06-21Restore reading authorized_keys2 by defaultColin Watson
Upstream seems to intend to gradually phase this out, so don't assume that this will remain the default forever. However, we were late in adopting the upstream sshd_config changes, so it makes sense to extend the grace period.

2019-06-21Don'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.

2019-06-21ssh(1): Refer to ssh-argv0(1)Colin Watson
Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks to ssh with the name of the host you want to connect to. Debian ships an ssh-argv0 script restoring this feature; this patch refers to its manual page from ssh(1).

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

2019-06-21Allow 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.

2019-06-21"LogLevel SILENT" compatibilityNatalie 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.

2019-06-05Various 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.

2019-06-05Handle 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. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1641 Bug-Debian: http://bugs.debian.org/394795 Last-Update: 2019-06-05 Patch-Name: selinux-role.patch
2019-06-05Restore 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: 2019-06-05 Patch-Name: restore-tcp-wrappers.patch
2019-06-05GSSAPI 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.
