delete all the contents of their destination.

This will be put back once the OpenSSH release is done.

destination directory if it doesn't already exist to match olde-scp(1)
behaviour. noticed by deraadt@ ok markus@

O_CREAT, the 3rd (variadic) mode_t parameter is irrelevant. Many developers
in the past have passed mode_t (0, 044, 0644, or such), which might lead
future people to copy this broken idiom, and perhaps even believe this
parameter has some meaning or implication or application. Delete them all.
This comes out of a conversation where tb@ noticed that a strange (but
intentional) pledge behaviour is to always knock-out high-bits from mode_t on
a number of system calls as a safety factor, and his bewilderment that this
appeared to be happening against valid modes (at least visually), but no
sorry, they are all irrelevant junk. They could all be 0xdeafbeef. ok

openbsd 7.0 release shipped with the (hopefully last) scp that uses RCP
protocol for copying. Let's get back to testing the SFTP protocol.

release. We'll wait a little longer for people to pick up sftp-server(8) that
supports the extension that scp needs for ~user paths to continue working in
SFTP protocol mode. Discussed with deraadt@

protocol remains available via the -O flag.
Note that ~user/ prefixed paths in SFTP mode require a protocol extension
that was first shipped in OpenSSH 8.7.

Do not add another "-s" to the argument vector every time an SFTP
connection is initiated. Instead, introduce a subsystem flag to
do_cmd() and add "-s" when the flag is set.

default. Replace recently added -M option to select the protocol with -O
(olde) and -s (SFTP) flags, and label the -s flag with a clear warning that
it will be removed in the near future (so no, don't use it in scripts!).

basename(3) and prevent a use-after-free in that case in the new sftp-compat
code.
POSIX allows basename(3) to either return a pointer to static storage
or modify the passed string and return a pointer to that. OpenBSD does
the former and works as is, but on other platforms "filename" points
into "tmp" which was just freed. This makes the freeing of tmp
consistent with the other variable in the loop.
Pinpointed by the -portable Valgrind regress test. ok djm@ deraadt@

scp, via a new "-M sftp" option. Marked as experimental for now.
Some corner-cases exist, in particular there is no attempt to
provide bug-compatibility with scp's weird "double shell" quoting
rules.
Mostly by Jakub Jelen in GHPR#194 with some tweaks by me. ok markus@
