add a whitelist of paths from which ssh-agent will load (via ssh-pkcs11-helper) a PKCS#11 module; ok markus@ Upstream-ID: fe79769469d9cd6d26fe0dc15751b83ef2a06e8f
2016-11-30upstream commitdjm@openbsd.org
Add a sshd_config DisableForwaring option that disables X11, agent, TCP, tunnel and Unix domain socket forwarding, as well as anything else we might implement in the future. This, like the 'restrict' authorized_keys flag, is intended to be a simple and future-proof way of restricting an account. Suggested as a complement to 'restrict' by Jann Horn; ok markus@ Upstream-ID: 203803f66e533a474086b38a59ceb4cf2410fcf7
2016-11-30upstream commitdjm@openbsd.org
When a forced-command appears in both a certificate and an authorized keys/principals command= restriction, refuse to accept the certificate unless they are identical. The previous (documented) behaviour of having the certificate forced- command override the other could be a bit confused and more error-prone. Pointed out by Jann Horn of Project Zero; ok dtucker@ Upstream-ID: 79d811b6eb6bbe1221bf146dde6928f92d2cd05f

On startup, check to see if sshd is already daemonized and if so, skip the call to daemon() and do not rewrite the PidFile. This means that when sshd re-execs itself on SIGHUP the process ID will no longer change. Should address bz#2641. ok djm@ markus@. Upstream-ID: 5ea0355580056fb3b25c1fd6364307d9638a37b9

Add a call to RAND_poll() to ensure than more than pid+time gets stirred into child processes states. Prompted by analysis from Jann Horn at Project Zero. ok dtucker@

Allow PuTTY interop tests to run unattended. bz#2639, patch from cjwatson at debian.org. Upstream-Regress-ID: 4345253558ac23b2082aebabccd48377433b6fe0

Reverse args to sshd-log-wrapper. Matches change in portable, where it allows sshd do be optionally run under Valgrind. Upstream-Regress-ID: b438d1c6726dc5caa2a45153e6103a0393faa906

Factor out code to disconnect from controlling terminal into its own function. ok djm@ Upstream-ID: 39fd9e8ebd7222615a837312face5cc7ae962885

use sshbuf_allocate() to pre-allocate the buffer used for loading keys. This avoids implicit realloc inside the buffer code, which might theoretically leave fragments of the key on the heap. This doesn't appear to happen in practice for normal sized keys, but was observed for novelty oversize ones. Pointed out by Jann Horn of Project Zero; ok markus@ Upstream-ID: d620e1d46a29fdea56aeadeda120879eddc60ab1

unbreak DenyUsers; reported by henning@ Upstream-ID: 1c67d4148f5e953c35acdb62e7c08ae8e33f7cb2
2016-11-06upstream commitdjm@openbsd.org
Validate address ranges for AllowUser/DenyUsers at configuration load time and refuse to accept bad ones. It was previously possible to specify invalid CIDR address ranges (e.g. djm@127.1.2.3/55) and these would always match. Thanks to Laurence Parry for a detailed bug report. ok markus (for a previous diff version) Upstream-ID: 9dfcdd9672b06e65233ea4434c38226680d40bfb

Improve pkcs11_add_provider() logging: demote some excessively verbose error()s to debug()s, include PKCS#11 provider name and slot in log messages where possible. bz#2610, based on patch from Jakub Jelen Upstream-ID: 3223ef693cfcbff9079edfc7e89f55bf63e1973d

2016-10-28Skip ssh1 specfic ciphers.Darren Tucker
cipher-3des1.c and cipher-bf1.c are specific to sshv1 so don't even try to compile them when Protocol 1 is not enabled.
2016-10-26upstream commitjsg@openbsd.org
Fix logic in add_local_forward() that inverted a test when code was refactored out into bind_permitted(). This broke ssh port forwarding for non-priv ports as a non root user. ok dtucker@ 'looks good' deraadt@ Upstream-ID: ddb8156ca03cc99997de284ce7777536ff9570c9

2016-10-26Use !=NULL instead of >0 for getdefaultproj.Darren Tucker
getdefaultproj() returns a pointer so test it for NULL inequality instead of >0. Fixes compiler warning and is more correct. Patch from David Binderman.
2016-10-24upstream commitdtucker@openbsd.org
Factor out "can bind to low ports" check into its own function. This will make it easier for Portable to support platforms with permissions models other than uid==0 (eg bz#2625). ok djm@, "doesn't offend me too much" deraadt@. Upstream-ID: 86213df4183e92b8f189a6d2dac858c994bfface

Remove ssh1 host key generation, add ssh-keygen -A
2016-10-21Update links.Darren Tucker
Make links to openssh.com HTTPS now that it's supported, point release notes link to the HTML release notes page, and update a couple of other links and bits of text.
2016-10-20Remote channels .orig and .rej files.Darren Tucker
These files were incorrectly added during an OpenBSD sync.
2016-10-19upstream commitdtucker@openbsd.org
Remove channel_input_port_forward_request(); the only caller was the recently-removed SSH1 server code so it's now dead code. ok markus@ Upstream-ID: 05453983230a1f439562535fec2818f63f297af9
2016-10-19upstream commitmillert@openbsd.org
Install a signal handler for tty-generated signals and wait for the ssh child to suspend before suspending sftp. This lets ssh restore the terminal mode as needed when it is suspended at the password prompt. OK dtucker@ Upstream-ID: a31c1f42aa3e2985dcc91e46e6a17bd22e372d69

2016-10-19Import readpassphrase.c rev 1.26.Darren Tucker
Author: miller@openbsd.org: Avoid generate SIGTTOU when restoring the terminal mode. If we get SIGTTOU it means the process is not in the foreground process group which, in most cases, means that the shell has taken control of the tty. Requiring the user the fg the process in this case doesn't make sense and can result in both SIGTSTP and SIGTTOU being sent which can lead to the process being suspended again immediately after being brought into the foreground.
2016-10-19Import readpassphrase.c rev 1.25.Darren Tucker
Wrap <readpassphrase.h> so internal calls go direct and readpassphrase is weak. (DEF_WEAK is a no-op in portable.)
2016-10-15Move DEF_WEAK into defines.h.Darren Tucker
As well pull in more recent changes from OpenBSD these will start to arrive so put it where the definition is shared.
2016-10-15Remove do_pam_set_tty which is dead code.Darren Tucker
The callers of do_pam_set_tty were removed in 2008, so this is now dead code. bz#2604, pointed out by jjelen at redhat.com.

Undo inconsistetly updated variable name.
2016-10-13upstream commitdjm@openbsd.org
fix the KEX fuzzer - the previous method of obtaining the packet contents was broken. This now uses the new per-packet input hook, so it sees exact post-decrypt packets and doesn't have to pass packet integrity checks. ok markus@ Upstream-Regress-ID: 402fb6ffabd97de590e8e57b25788949dce8d2fd

Unregister the KEXINIT handler after message has been received. Otherwise an unauthenticated peer can repeat the KEXINIT and cause allocation of up to 128MB -- until the connection is closed. Reported by shilei-c at 360.cn Upstream-ID: 43649ae12a27ef94290db16d1a98294588b75c05

revision 1.23 date: 2010/05/14 13:30:34; author: millert; state: Exp; lines: +41 -39; Defer installing signal handlers until echo is disabled so that we get suspended normally when not the foreground process. Fix potential infinite loop when restoring terminal settings if process is in the background when restore occurs. OK miod@
2016-10-13If we don't have TCSASOFT, define it to zero.Darren Tucker
This makes it a no-op when we use it below, which allows us to re-sync those lines with the upstream and make future updates easier.
