Apply the same get_remote_name_or_ip -> session_get_remote_name_or_ip
change as commit 95767262 to the code inside #ifdef LOGIN_NEEDS_UTMPX.
Fixes build on AIX.
Remove "POSSIBLE BREAK-IN ATTEMPT!" from log message
about forward and reverse DNS not matching. We haven't supported IP-based
auth methods for a very long time so it's now misleading. part of bz#2585,

There are a small number of "upstream" commits that do not correspond to
a file in -portable. This file tracks those so that we can reconcile
OpenBSD and Portable to ensure that no commits are accidentally missed.
If you add something to .skipped-commit-ids please also add an upstream
ID line in the following format when you commit it.

Back out rev 1.28 "Check min and max sizes sent by the
client" change. It caused "key_verify failed for server_host_key" in clients
that send a DH-GEX min value less that DH_GRP_MIN, eg old OpenSSH and PuTTY.

Where possible, use Solaris setpflags to disable process tracing on
ssh-agent and sftp-server. bz#2584, based on a patch from huieying.lee
at oracle.com, ok djm.
Fix two rare edge cases: 1. If vasprintf() returns < 0,
do not access a NULL pointer in snmprintf(), and do not free() the pointer
returned from vasprintf() because on some systems other than OpenBSD, it
might be a bogus pointer. 2. If vasprintf() returns == 0, return 0 and ""
rather than -1 and NULL.
Besides, free(dst) is pointless after failure (not a bug).
One half OK martijn@, the other half OK deraadt@;
committing quickly before people get hurt.

Backout rev. 1.43 for now.
The function update_progress_meter() calls refresh_progress_meter()
which calls snmprintf() which calls malloc(); but update_progress_meter()
acts as the SIGALRM signal handler.
"malloc(): error: recursive call" reported by sobrado@.

Even when only writing an unescaped character, the dst
buffer may need to grow, or it would be overrun; issue found by tb@ with
malloc.conf(5) 'C'.
While here, reserve an additional byte for the terminating NUL
up front such that we don't have to realloc() later just for that.
OK tb@

To prevent screwing up terminal settings when printing to
the terminal, for ASCII and UTF-8, escape bytes not forming characters and
bytes forming non-printable characters with vis(3) VIS_OCTAL. For other
character sets, abort printing of the current string in these cases. In
particular, * let scp(1) respect the local user's LC_CTYPE locale(1); *
sanitize data received from the remote host; * sanitize filenames, usernames,
and similar data even locally; * take character display widths into account
for the progressmeter.
This is believed to be sufficient to keep the local terminal safe
on OpenBSD, but bad things can still happen on other systems with
state-dependent locales because many places in the code print
unencoded ASCII characters into the output stream.
Using feedback from djm@ and martijn@,
various aspects discussed with many others.
deraadt@ says it should go in now, i probably already hesitated too long
