John Safranek 399c83b1b6 coverage: survive a truncated raw profile
The merge step takes --failure-mode=all, so a raw profile left short by
a killed process is warned about and skipped instead of aborting the
report. Tests SIGKILL their servers in cleanup traps, and a process
killed while writing its profile leaves a corrupt header behind. The
step still fails when no profile can be read at all.

John Safranek 65802d438c internal: commit a session only once accepted
A shell, exec or subsystem request changes the channel only once the
callback accepts it. The session type and command are set for the
callback to read and put back if it refuses, and CLIENT_DONE follows
acceptance alone, so wolfSSH_accept() stays where it is rather than
reporting a session it answered CHANNEL_FAILURE as established.

- DoChannelRequestSession() carries the three arms, which differed only
  in the type and the callback consulted
- a refusal puts the type and command back, so a grant an earlier
  request won still stands
- FreeChannelCommand() wipes and releases a command line for both
  ChannelDelete() and the refusal path
- unit.c drives a refused shell, exec and subsystem request through
  DoChannelRequest() and checks nothing was committed, and that a
  refusal after a grant puts the earlier command back whole
- regress.c checks accept() stays at ACCEPT_SERVER_CHANNEL_ACCEPT_SENT
  on a refused shell, and that the sftp gate and both diverts ask for
  the grant alone

Yosuke Shimizu a14e6d0f3c ssh, apps, examples: take the worker's status from its return
- wolfSSH_OutputPending() moves from wolfssh/internal.h to
  wolfssh/ssh.h as a WOLFSSH_API taking a const WOLFSSH*, defined
  in src/ssh.c beside the other public calls.
- wolfSSH_worker() puts the send's code in the return in place of
  an event when the flush fails outright, and gates its flush on
  wolfSSH_OutputPending(). wolfssh/ssh.h states both.
- Both wolfsshd shell loops, both echoservers and
  ReceiveScpMessage() dispatch on wolfSSH_worker()'s return, and
  call wolfSSH_get_error() only to tell a transient failure from a
  terminal one. The POSIX wolfsshd loop sets wantWrite from
  wolfSSH_OutputPending().
- Five worker tests expect the send's code where they expected the
  event, and tests/testsuite.c calls wolfSSH_OutputPending().

Yosuke Shimizu 5ea9b736de scp: drain extended data in the SCP read path
- ScpStreamRead() calls _DumpExtendedData() and reads again when
  wolfSSH_stream_read() returns WS_EXTDATA, reporting the drain's
  own failure when it has one.
- ReceiveScpConfirmation() drops its WS_EXTDATA arm and reports a
  negative read directly.
- ReceiveScpMessage() returns _DumpExtendedData()'s failure in place
  of discarding it.

John Safranek 2a15157cf6 scp, apps: correct three ssh->error reads
ReceiveScpConfirmation() takes a WS_EXTDATA off ScpStreamRead()'s
return, the rule ssh.h now states for reading an event.
FlushQueuedSend() samples the owed write with the session still
locked, since the peer reader thread writes ssh->error too, and
reports a send that failed there over the event it rode in on.

- A pass that delivers stderr while its flush short-writes returns
  WS_EXTDATA with WS_WANT_WRITE in ssh->error, so the confirmation
  read aborted the transfer with the stderr undrained.
- wolfSSH_stream_read() on the reader thread clears ssh->error with
  this thread's packet still queued, which ended the flush early and
  reported it a success.
- An event return with a hard send error latched collapsed to
  WS_SUCCESS, telling the caller a queued packet reached a socket
  that was gone.

Yosuke Shimizu 21deb724fe scp, test.h, apps, examples: wait to write and route on the return
- tcp_select_write() joins tcp_select(), with WS_SELECT_SEND_READY
  at the end of the enum. tcp_select() passes NULL for writefds and
  cannot wait on the write side.
- The Windows wolfsshd window-change drain and sftp_worker()'s
  handshake flush retry wait on it. The drain records a give-up in
  ret, and sftp_worker() breaks only on WS_SELECT_ERROR_READY.
- The echoserver, Espressif and both wolfsshd shell loops, and
  ReceiveScpMessage(), take the event from wolfSSH_worker()'s
  return when it carries one, in place of reading ssh->error alone.
  The two echoservers cover WS_CHAN_RXD, WS_REKEYING,
  WS_CHANNEL_CLOSED and WS_EOF; the wolfsshd loops and
  ReceiveScpMessage() cover the ones they have arms for.
- The POSIX wolfsshd loop takes an owed write into wantWrite before
  the event overwrites rc, and its WS_WANT_WRITE arm runs the
  channel drain below in place of skipping it.
- FlushQueuedSend() folds the receive's own statuses into
  WS_SUCCESS inside its loop and keeps flushing while
  wolfSSH_get_error() reports WS_WANT_WRITE within the deadline, in
  place of looping on the worker's return. It reports
  WS_WANT_WRITE when the deadline leaves the packet queued.

Yosuke Shimizu 586b697b18 ssh, internal: always flush the worker's output
- wolfSSH_worker() calls wolfSSH_SendPacket() whenever
  ssh->outputBuffer holds bytes and the session is not
  disconnected. ssh->error keeps the receive's code when the
  receive failed, and the close's when a WS_CHANNEL_CLOSED pass
  hard-failed its flush; WS_REKEYING is withheld on a failed
  flush. Drops the second DoReceive(), the WOLFSSH_TEST_BLOCK
  fork and the separate WS_CHANNEL_CLOSED flush.
- BundlePacket() resets ssh->outputBuffer.length to
  ssh->packetStartIdx when the framing fails. wolfSSH_shutdown()
  reports WS_WANT_WRITE when its close-read leaves output queued,
  and the send's own error in place of it when that send failed.
  SendPacketFlush() records its code in ssh->error on every
  transport failure path, and wolfSSH_TriggerKeyExchange() writes
  it only when SendKexInit() fails.
- portfwd, client and scpclient accept WS_WANT_WRITE from
  wolfSSH_shutdown(); in scpclient the close-message drain runs
  on it.
- wolfssh/ssh.h drops WS_WINDOW_FULL from wolfSSH_worker() and says
  to read the return and wolfSSH_get_error() as independent channels
  on every pass.
- Twenty unit tests and the extended TestWorkerReportsDisconnect
  cover what ret and ssh->error hold after a receive, send, buffer,
  callback or framing failure.

Yosuke Shimizu ab979865aa apps, examples: tolerate a worker want-write
- The echoserver and Espressif shell loops and the Windows
  wolfsshd shell loop treat a WS_WANT_WRITE from wolfSSH_worker()

John Safranek 28bf47d2a0 tests: pin the get_fd invalid-socket sentinel
test_wolfSSH_set_fd() compares the NULL return of wolfSSH_get_fd()
against the platform invalid-socket sentinel, the value wolfSSH_new()
initializes rfd/wfd to. The old check only asserted the result was not
WS_SUCCESS, which the previous WS_BAD_ARGUMENT return also satisfied.

John Safranek ae81d4d857 ssh: divert only into a granted session
wolfSSH_accept() hands a session to the built-in SCP or SFTP server
only when the request naming it was answered CHANNEL_SUCCESS. A
callback that refuses one sends CHANNEL_FAILURE, yet sessionType and
command are recorded ahead of that answer and stay set, so the diverts
read a refused session as a served one.

- gate both diverts on channel->sessionGranted, as
  wolfSSH_SFTP_accept() already gates the app-channels path
- the SCP divert tests the channel list itself, having no command
  lookup ahead of it to do that
- cover each divert with a refused request and a granted control

John Safranek 3437d6f2cc internal: drop an always-true guard
DoChannelRequest() returns early when the header parse fails, so the
ret == WS_SUCCESS test that followed it could never be false. The
channel lookup moves into the else, which is the only way the function
reaches it.

John Safranek 0a9b44a962 internal: scrub the channel command on free
The peer's exec or subsystem command line is wiped ahead of both frees
that release it, ChannelDelete() and the GetStringAlloc() that replaces
it on a repeat request, the way ChannelDelete() already wipes the
decrypted inputBuffer just above. A command line can carry a password
or a token among its arguments.

- ScrubChannelCommand() leaves the free to GetStringAlloc(), so a parse
  that fails behind it holds no dangling pointer
- cover both wipes with the retain-on-free allocator, the replacement
  through wolfSSH_TestDoChannelRequest()
- release the test's hand-built channel on a setup failure

John Safranek ff1f82f547 internal: act on a session request only if parsed
DoChannelRequest() records the session type and asks the exec and
subsystem callbacks whether to grant a session only when the command
string parsed. A failed parse is refused on ret alone, and
channel->command still holds an earlier request's value rather than the
one being answered.

- cover a command length header running past the end of the packet, on
  exec and on subsystem

John Safranek 9c8caea8b5 ssh: expose the session command length
An application vetting an exec or subsystem request in its channel
request callback is handed the command as a C string, which stops at an
embedded NUL. wolfSSH_ChannelGetSessionCommandSz() and
wolfSSH_GetSessionCommandSz() report the parsed wire length, so a
callback can match a name whole the way DoChannelRequest() does.

- both accessors report 0 for a NULL channel or session
- wolfSSH_GetSessionCommand() defers to the channel accessor
- the sftp divert in wolfSSH_accept() asks the accessor for the length
- correct the trace name in wolfSSH_ChannelGetSessionCommand()
- cover a callback seeing "sftp\0evil" through exec and subsystem

John Safranek 44a348f01a tests: check the rejecting callback actually ran
CheckSftpAcceptRefusesUngranted() drives the same refusal two ways, a
registered subsystem callback saying no and app channels standing in
for a missing one, and asserted nothing that told them apart. Assert
the call count each case expects.

John Safranek 3516fb00a0 ssh, sftp: match the sftp subsystem name exactly
The built-in SFTP server takes a session only when the subsystem name
is sftp, matched whole. DoChannelRequest() keeps the parsed length in
channel->commandSz, so neither wolfSSH_SFTP_accept()'s grant gate nor
wolfSSH_accept()'s divert serves "sftpx" or "sftp\0evil".

- cover a granted name longer than sftp, one of its length, and one
  running past an embedded NUL
- cover the divert with those three names and a control that diverts
- exec keeps its command length too

John Safranek 7adf524f6f sftp: require a granted subsystem to serve
wolfSSH_SFTP_accept() serves an application-driven session only on a
channel whose subsystem request was answered CHANNEL_SUCCESS.
DoChannelRequest() records the session type and command before it
decides, and leaves both set on a refusal, so they cannot say by
themselves whether anything was granted.

- add channel->sessionGranted, set from the answer a shell, exec or
  subsystem request gets rather than from the request arriving
- look the channel up again before recording it: a callback may close
  its own channel, and wolfSSH_ChannelFree() frees it
- log a request's strings where they are known good: once the parse
  has succeeded, and ahead of a callback that may free the channel
- gate the app-channels path on that flag alongside the session type
  and the command
- cover a refusal from both sides, no callback registered and a
  callback that rejects, and a callback that frees its channel

John Safranek 742f327ed4 sftp: serve app-channels only on a granted sftp
In application-driven mode wolfSSH_accept() parks at userauth, so the
sftp test its divert applies never runs. wolfSSH_SFTP_accept() applies
it itself: the session channel must be a subsystem the application's
callback granted sftp on, or the call returns WS_INVALID_STATE_E and
leaves the wire alone without recording an error.

- gate the app-channels branch on wolfSSH_GetSessionType() and
  wolfSSH_GetSessionCommand(), the same test accept() makes
- ask for that grant in every accept state: below the user-auth stop
  accept() returns with no channel open, and past the stop there is no
  accept() left that could have checked anything
- say in ssh.h that the mode serves SFTP through that grant and never
  reaches the SCP entry point
- regress.c refuses the call with no channel, ahead of accept(), on a
  granted shell and on an established one, and serves an INIT on a
  granted sftp subsystem

John Safranek 4ac4484afd ssh: correct what a late app-channels enable does
DoChannelRequest() reads ssh->appChannels when the request arrives, so
turning the mode on after accept() established the session still refuses
an uncallbacked shell, exec or subsystem request from then on. Only
accept()'s stopping point is pinned, by the guard around stopState.

- say the flag reaches the requests that follow, and that what it cannot
  do is move where accept() returns
- drive a shell request over the wire in both modes from the late-enable
  test, pinning the behaviour the header now describes

John Safranek 2c832010d2 tests: cover application-driven channels
wolfSSH_SetAppChannels() changes where wolfSSH_accept() stops and what
becomes of a session request with no callback behind it, so both modes
are exercised.

- regress.c drives a server with the pivot on, one with a shell
  callback and one without, and checks accept() stops at
  ACCEPT_SERVER_USERAUTH_SENT
- regress.c pins the context setter, the session's inheritance of it,
  and that turning it on after accept() established the session still
  returns
- regress.c re-enters a parked accept() with output still queued, which
  is the one path that flushes before reading the state, and pins that
  it leaves the state on the stop
- unit.c checks DoChannelRequest() refuses a shell, exec and subsystem
  request with no callback once the pivot is on
2026-09-10 17:14:23 -07:00
John Safranek b723519312 ssh: add opt-in application-driven channels
A server that wants to own its channels had no way to get them: accept()
ran the session state machine to the end, and a shell, exec or subsystem
request with no callback registered was granted regardless.

- add wolfSSH_CTX_SetAppChannels() and wolfSSH_SetAppChannels(), off by
  default, a byte on the context copied into the session
- on, accept() returns once the user is authenticated, and a session
  request with no callback behind it is refused: nothing is left to serve
- keep the stop state out of the pending-send advance, so a re-entry with
  queued output cannot step over where this call is meant to stop
- stop early only while the session is short of that state, so turning the
  mode on afterward cannot leave the loop hunting a state it went past
- teach wolfSSH_SFTP_accept() that the mode parks accept() short of an
  established session, so it stops redoing the handshake on every poll

Yosuke Shimizu c039486e52 scp: return directory entries from the Zephyr entry walk
- The WOLFSSH_ZEPHYR branch of FindNextDirEntry() loops while the
  entry name is "." or "..", matching the POSIX and Windows
  branches, in place of while (1).
- tests/api.c gains test_wolfSSH_SCP_SendRecursiveEntry(), staging a

  otherwise, and is called from wolfSSH_ApiTest().

Yosuke Shimizu d3ad9fa5ed internal: gate auth-agent channel opens on the client's request
- DoChannelOpen refuses an auth-agent open on a server endpoint, and on
  a client with the agent disabled or connectState below
  CONNECT_CLIENT_CHANNEL_AGENT_REQUEST_SENT.
- Both answer OPEN_ADMINISTRATIVELY_PROHIBITED; the ssh->agent check
  stays as the resource check behind them.
- Cover the refusals before the request, with the agent disabled, over
  an accepting channelOpenCb, and on a server, plus the accepted open
  past the request; each refusal asserts ssh->error stays clean.
- Move TestAgentChannelNullAgentSendsOpenFail to a client harness, and
  have the agent tests set the agent flag explicitly.

Hideki Miyazaki e04a29784f windows-check: Cache the wolfSSL build in mingw-regress
Every run of this job rebuilt wolfSSL --enable-all from source on a
Windows runner, about five minutes, even though the ref is pinned
and the configure flags never change between runs.

Add an actions/cache step keyed on wolfssl-mingw-regress-wolfssl-
<ref>-windows-latest, matching the naming singlethread-check.yml and
x509-interop.yml use. Those two split the work into a build_wolfssl
job and a build_wolfssh job, with a lookup-only cache check in the
first and a fail-on-cache-miss restore in the second. This job has
no such split, so it uses a single plain actions/cache step instead:
it restores on a hit and saves automatically after the job on a
miss.

The MSYS2 shell's $HOME lives under setup-msys2's own temp install
directory, not a path stable across runner images, so build to
${{ github.workspace }}/wolfssl-install instead: actions/cache
resolves a relative path against GITHUB_WORKSPACE, and cygpath -u
gives the msys2 shell steps the same directory as $WOLFSSL_INSTALL.

Hideki Miyazaki 343582a61e tests: Key regress.c's Windows portability macros on _WIN32
TEST_NULL_DEVICE, TEST_SETENV, TEST_UNSETENV, and TEST_MKDIR were
gated on USE_WINDOWS_API, while the arpa/inet.h/direct.h include
guard a few lines above keys on _WIN32. Whether mkdir(), setenv(),
and /dev/null work as expected is a libc availability question, not
a wolfSSH API-selection one, so _WIN32 is the more direct fit and
now both guards in this file agree.

No behavior change: USE_WINDOWS_API is only ever set when _WIN32 is
already defined, so this does not change which branch any current
build takes.

Verified with the MinGW cross compiler both with WOLFSSH_SFTP defined
and without, and confirmed a plain Linux build still passes
tests/regress.test and tests/unit.test.

Hideki Miyazaki 0bb371a4b2 windows-check: Pin wolfssl to v5.9.1-stable in mingw-regress
The wolfssl checkout in mingw-regress had no ref, so it always built
against wolfssl/wolfssl's default branch. An upstream change there
could break this job with nothing changed on the wolfssh side to
explain it, and this job in particular turned out to be sensitive to
exact wolfSSL build details while it was being brought up.

Pin it to v5.9.1-stable, the same tag singlethread-check.yml and
x509-interop.yml already use, confirmed to include wc_mlkem.c so the
ML-KEM coverage this job exercises is still built. The build and
asan-tests jobs in this file have the same unpinned checkout but are
left alone here, since they were not touched by this change.

Hideki Miyazaki 82032bddfe tests: Stop TestKnownHostsLastEntry depending on WMKDIR
A local run with ./configure --enable-smallstack (no --enable-sftp)
showed WMKDIR as an implicit, undeclared function under MinGW.
wolfssh/port.h only defines WMKDIR when WOLFSSH_SFTP, WOLFSSH_SCP, or
WOLFSSH_SSHD is enabled, but TestKnownHostsLastEntry itself is gated
on WOLFSSL_BASE64_ENCODE alone, so it compiles in configurations
where none of those three are on and WMKDIR does not exist.

Add a small TEST_MKDIR macro next to the existing TEST_SETENV and
TEST_UNSETENV ones, backed directly by _mkdir() under USE_WINDOWS_API
and mkdir() otherwise, and use it in place of WMKDIR. The Windows
branch needs direct.h for _mkdir's declaration; include it next to
the existing _WIN32 guard around arpa/inet.h at the top of the file.

Verified with the MinGW cross compiler both with WOLFSSH_SFTP defined
and without, and confirmed a plain Linux build configured with
--enable-smallstack (no --enable-sftp) still passes tests/regress.test
and tests/unit.test.

Hideki Miyazaki 53683a758c tests: Use the Windows null device in the known_hosts regression test
The next mingw-regress failure after the previous fix was
TestKnownHostsLastEntry failing its "ready" assertion. It calls
open("/dev/null", O_RDONLY) to point stdin at EOF while it drives the
known_hosts prompt, but Windows has no /dev/null; the call simply
fails there, so open() returns -1 and every check gated on ready is
skipped.

Add a TEST_NULL_DEVICE macro that resolves to "NUL" under
USE_WINDOWS_API and "/dev/null" otherwise, and use it at both call
sites in this file: TestKnownHostsLastEntry, and the same pattern in
TestPasswordEofNoCrash a bit earlier, which happens to be masked in
CI by its own isatty() guard but would hit the same bug if ever run
against a real terminal on Windows.

Hideki Miyazaki 4df003061a apps/wolfssh: Write known_hosts entries in binary mode
CI's mingw-regress job showed AppendKeyToFile writing a known_hosts
entry, then TestAppendKeyToFile reading it back and finding a byte
mismatch on Windows. The file was opened with WFOPEN(..., "a"), a
text mode append. On Windows the C runtime rewrites '\n' to CRLF on
write in text mode, so the entry landed on disk with a trailing
"\r\n" instead of the "\n" the test wrote and expected back.

Open the file in binary mode instead, matching the WriteTextFile test
helper a few hundred lines above in tests/regress.c, which already
uses "wb" for the same reason. known_hosts is conventionally
LF-terminated regardless of platform, so this also matches the format
other SSH clients expect from the file, not just the test.

Hideki Miyazaki 6d163a87d9 Fix remaining MinGW build errors in the regress/unit test build
apps/wolfssh/common.c declared a CONSOLE_SCREEN_BUFFER_INFO local in
ClientSetEcho that nothing ever read; the Windows echo toggling never
grew the code that would have used it. Drop the unused declaration.

wolfssh/port.h defined WSTRSEP as strsep(), a BSD extension MSVCRT
and MinGW do not provide. Add a portable wstrsep() in src/port.c,
matching the wstrnstr/wstrncat/wstrdup pattern already used for other
missing string functions, and route WSTRSEP through it under
USE_WINDOWS_API.

tests/regress.c called the two argument POSIX mkdir(path, mode) and
setenv()/unsetenv() directly in TestKnownHostsLastEntry. Use the
existing WMKDIR macro for the directory creation, and add small
TEST_SETENV/TEST_UNSETENV macros backed by _putenv_s() on Windows so
the HOME juggling this test does still works there.

src/wolfsftp.c had three separate issues in code paths that had never
been compiled before this job existed. wolfSSH_SFTP_RecvOpen declared
a flagsAndAttrs DWORD that nothing read, since WS_CreateFileA is
called with a hardcoded FILE_ATTRIBUTE_NORMAL instead.
wolfSSH_SFTP_RecvOpenDir compared a signed loop counter against a
sizeof expression while building ssh->driveList, so make the counter
word32. wolfSSH_SFTP_Put passed &state->rSz, an int, to ReadFile()'s
DWORD* output parameter; read into a local DWORD and copy it into
state->rSz afterward, since that field is also assigned from
WFREAD() on non-Windows builds.

src/wolfterm.c's wolfSSH_DoOSC never used its handle parameter. Mark
it with WOLFSSH_UNUSED rather than removing it, since the parameter
matches the signature its two call sites already pass and future OSC
handling such as window titles is a natural use for it.

Verified against a real x86_64-w64-mingw32 cross compiler with a
config.h edited to match the sizes and header availability the
actual Windows CI run reported (SIZEOF_LONG 4, HAVE_SYS_IOCTL_H
undefined, and so on): every file this job compiles builds cleanly
under the same -Werror flag set. Also reconfirmed a clean, unmodified
Linux build still passes both tests/regress.test and tests/unit.test.

Hideki Miyazaki 83a2246471 Fix three MinGW -Werror build failures in the regress/unit test build
MinGW-w64 does not ship arpa/inet.h; guard tests/regress.c's include
the same way apps/wolfsshd/auth.c already does, since htonl/ntohl end
up declared via the winsock2.h wolfSSL's headers pull in later in the
same translation unit.

wolfssh/test.h guarded its MSVC #pragma warning(disable:4996) with
USE_WINDOWS_API alone, which is also true for MinGW's gcc; gcc treats
the unrecognized pragma as an error under -Werror. Require _MSC_VER
too, matching the existing ALIGN16 pragma guard in wolfssh/internal.h.

wolfSSH_CleanPath's Windows/Nucleus drive-letter cleanup re-declared
`i` in a nested scope, shadowing the function's own `i` used by every
other loop in the function. Hoist `j` to the function's declarations
(guarded by the same #if so non-Windows/Nucleus builds don't get an
unused-variable warning) and drop the now-unnecessary block so the
loop reuses the outer `i`.

Verified locally: autoreconf + configure + make tests/regress.test
tests/unit.test builds clean and both binaries pass on Linux.

Hideki Miyazaki 4105c2242c windows-check: Build the .exe-suffixed regress/unit test targets on MinGW
The new run showed the ws2_32/crypt32 link fix worked (configure
passed) but make then failed: "No rule to make target
'tests/regress.test'." Reproducing the autotools build locally
confirmed why: MinGW's EXEEXT is ".exe", so automake's check_PROGRAMS
rule names the binaries tests/regress.test.exe and tests/unit.test.exe,
not the extension-less names this job was asking make to build and run.

Hideki Miyazaki 90ce9fb61b windows-check: Link ws2_32 and crypt32 for the mingw-regress wolfssh build
config.log from a failing run showed the wolfCrypt_Init AC_CHECK_LIB
probe pulling in ssl.c/internal.c/wolfio.c from the static
libwolfssl.a, leaving Winsock (socket, send, recv, inet_pton, ...) and
cert store (CertOpenSystemStoreA, ...) symbols unresolved. A shared
build would defer that resolution to the DLL; the static archive here
needs ws2_32 and crypt32 passed explicitly via LIBS.

Hideki Miyazaki 3532cc4432 windows-check: Print config.log on mingw-regress failure
The mingw-regress job's wolfssh configure step fails with
"libwolfssl is required for wolfssh" even though libwolfssl.a is
installed at the expected path. AC_CHECK_LIB only reports pass/fail;
dump config.log on failure to see the actual link error.

Hideki Miyazaki 39fec50df2 wolfsshd: Cover -D option parsing on Windows in CI
The Windows StartSSHD() path rebuilds argv from GetCommandLineW(). A
regression there left -D foreground mode walking the raw wide command
line, so -f and -p were ignored and the daemon used its built-in
defaults. Nothing in CI caught that.

Add sshd_dash_d_test.ps1: it starts wolfsshd with -D and a config file
at a non-default path whose Port line differs from the -p value, then
checks the listener binds the -p port and not the config port. That
holds only when -D mode parsed both -f and -p. Run it from the Windows
build job next to the existing LoginGraceTime check.

Hideki Miyazaki ea30c9fd9d Run the SFTP regression tests on Windows under MSYS2
tests/regress.c holds the only coverage for the Windows SFTP open path,
including TestSftpWindowsOpenFlagMatrix, which walks the RecvOpen
CREAT/EXCL/TRUNC/APPEND matrix against the CreateFile() disposition
table. That test is guarded by USE_WINDOWS_API and ran in no CI job. The
MSVC solution in ide/winvs has no regress project, and regress.c does not
build with cl because it includes arpa/inet.h and unistd.h, so the
disposition fix it locks down could regress unnoticed.

Add an MSYS2 MinGW64 job to the Windows workflow. MinGW defines _WIN32,
so wolfssh/settings.h turns on USE_WINDOWS_API and the Windows-only
branches compile and run. The job builds wolfSSL static, configures
wolfSSH with --enable-sftp, and runs tests/regress.test and
tests/unit.test. wolfsshd is left out: its autotools path is not
MinGW-clean and the MSVC solution already covers it.

Aidan Keefe 155a4e1c47 Validate a custom SSH proto ID string
wolfSSH_CTX_SetSshProtoIdStr() now rejects a string that is not
CRLF-terminated, exceeds 255 bytes counting the terminator, or
carries a CR or LF in the body. DoKexInit() subtracts the two
terminator bytes from the length when hashing it, so an
unterminated string underflowed the hash length.

Yosuke Shimizu 8d6e2b3aba wolfsshd: complete the Windows user profile fallback
- _GetHomeDirectory loads the user's profile when WOLFSSHD_AUTH's new
  profile member is NULL, setting PROFILEINFO.dwSize first and keeping
  the returned hProfile there.
- _GetProfileDirectory reads the home directory with
  GetUserProfileDirectoryW, in place of SHGetKnownFolderPath and the
  %USERPROFILE% expansion. CheckPublicKeyWIN calls it directly, so a
  caller that has not authenticated the user builds no profile.
- wolfSSHD_AuthCloseToken unloads the profile before closing the token,
  calling RegCloseKey when the unload fails.
- The Windows shell cleanup calls RevertToSelf() before closing the auth
  token rather than after.
- windows-sftp.yml gains a no_profile job that covers an exec session,
  two overlapping sessions, and SFTP for users created with net user
  alone; it skips the earlier SFTP step so its exec session connects
  first.
- Both Windows workflows log testuser on once so Windows builds a real
  profile, in place of writing the home directory and ProfileList entry
  by hand, and the recursive icacls grants on it are gone.

Yosuke Shimizu dee02b2289 ci: cover recursive SCP on Windows
- windows-sftp.yml generates an ecdsa key for testuser, authorizes it,
  and builds a source tree holding two files, a nested subdirectory
  and an empty one.
- A new step pulls that tree with scp -O -r and fails unless every
  file and directory arrives. -O keeps OpenSSH on the legacy SCP
  protocol rather than SFTP.
- The header comment lists the recursive SCP scenario.

Yosuke Shimizu 29762a64c6 port, scp: distinguish end of directory from enumeration failure
- WS_FindNextFileA_ex() takes a lastError out-parameter and carries
  the body of WS_FindNextFileA(), which now calls it with NULL. A
  failing return reports the FindNextFileW() error, or
  ERROR_NO_UNICODE_TRANSLATION when the name would not convert.
- FindNextDirEntry() calls WS_FindNextFileA_ex() on Windows. An
  ERROR_NO_MORE_FILES result frees ctx->entry, sets it to NULL and
  returns WS_NEXT_ERROR so the caller pops the directory; every other
  error still returns WS_FATAL_ERROR.

John Safranek e7a05229ad agent: commit the open on a completed flush
wolfSSH_AGENT_ChannelOpen() settles its channel and agent on whether
the open reached the peer, which SendPacketDelivered() answers from the
flush count. The highwater callback runs after the last byte is out, so
its failure arrives as this send's return, and the rollback read that
as a send that never left.

- give SendPacketDelivered() external linkage, contract in internal.h
- note in agent.h that an error raised once the open is on the wire
  leaves the channel open
- test a failing highwater callback: the channel and the agent stand,
  and the poll after it is the idempotent one

John Safranek 6164ec39d5 agent: refuse a channel open after a disconnect
wolfSSH_AGENT_ChannelOpen() answers a poll on a session that is over
with WS_FATAL_ERROR and WS_DISCONNECT in ssh->error, the shape every
other public sender uses: no channel opened, nothing on the wire,
RFC 4253 section 11.1. wolfSSH_accept() gates the open it drives, so
the new public entry point is the only way in.

- promote SendAfterDisconnect() to WOLFSSH_LOCAL so agent.c uses the
  same helper as every other public sender
- leave an open queued before the disconnect unflushed, the rule
  wolfSSH_shutdown() applies to all but its own disconnect
- keep WS_DISCONNECT in ssh->error at the accept() call site, which
  used to overwrite it with the status the open returns

John Safranek 41f171d982 agent: let the application open the agent channel
The one server-side site that opens auth-agent@openssh.com sits inside
wolfSSH_accept(), so an application driving its own channels cannot
reach it: the session records the request and no channel follows.

- add wolfSSH_AGENT_ChannelOpen(), the same open lifted out of accept(),
  which still calls it
- it reports WS_BAD_ARGUMENT until the peer asks and on a client
  session, and is idempotent after, so an application can poll it
- publish the agent on a queued open too, so a retry after WS_WANT_WRITE
  finds it rather than opening a second channel and leaking the first
- flush what is left of a queued open on the next call, rather than
  reporting a success the peer never saw
- record ssh->error from the send alone, so neither a poll ahead of the
  request nor a failed allocation stops accept() continuing

John Safranek 85f7978eb4 SCP: report only a read want from SCP_accept
wolfSSH_SCP_accept() reported any want held in ssh->error in place of
the DoScpRequest() result. A short send that SendChannelData() accepts
leaves WS_WANT_WRITE there with nothing clearing it on a later flush,
so a terminal result came back as retryable and the retry re-entered
the state machine, re-sending an abort confirmation or reading past a
bad message.

- Substitute the want only when the result is WS_FATAL_ERROR and the
  want is WS_WANT_READ, the one case GetInputData() hides by value.
- Leave write wants alone; the SCP state machine already returns them.

John Safranek 13b9e39f90 SCP: let the application start the transfer
An application that binds an "scp ..." command to a channel itself has no
way to run the transfer; wolfSSH_accept() did it through a WS_SCP_INIT
re-entry only that state machine can drive.

- add wolfSSH_SCP_accept(), a wrapper over DoScpRequest() reporting
  WS_SCP_COMPLETE for any non-negative result, as accept() does
- a receive-side want reaches the wrapper as a generic error with the
  want in ssh->error, so report the want itself and let the caller retry
- state that resume contract beside the prototype, and clear a stale want
  on entry the way the other re-entrant entry points do

John Safranek ba6bc667a9 portfwd: report the channel open response
wolfSSH_CTX_SetChannelOpenRespCb() had no caller anywhere in the tree, so
the confirm and fail hooks had no worked example and a forwarding client
had nothing to say which of its opens the peer refused.

- register both arms and print the channel each one names
- name our own id, not the peer's: a refused open never learns the peer's,
  and it is the id portfwd_worker() already tracks
