control over some SFTP protocol knobs: the copy buffer length and
the number of inflight requests, both of which are used during
upload/download.
Previously these could be controlled in sftp(1) using the -b/-R options.
This makes them available in both SFTP protocol clients using the same
option character sequence.

default), better match scp/rcp's handling of globs that don't match the
globbed characters but do match literally (e.g. trying to transfer
"foo.[1]").
Previously scp(1) in SFTP mode would not match these pathnames but
legacy scp/rcp mode would.

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

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

supports the extension that scp needs for ~user paths to continue working in
SFTP protocol mode. Discussed with deraadt@

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.

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@

Some corner-cases exist, in particular there is no attempt to
provide bug-compatibility with scp's weird "double shell" quoting
rules.

preventing races between handlers, and sets SA_RESTART which should reduce
the potential for short read/write operations.
