Refactor of the echoserver example only; library is unchanged.
1. Collapse FwdStates and AGENT_STATE_* into a single WS_AppState
(INIT/LISTEN/CONNECT/CONNECTED). FWD_STATE_DIRECT becomes an
isDirect flag, cleared after connect.
2. Hoist the fields shared by the forwarding, agent, and shell paths
into a common WS_AppCtx (privateData, listenFd, appFd, channelId,
state, buffer). Shell only uses buffer.
3. Feature-specific remainder stays in WS_AgentCbActionCtx (name) and
WS_FwdCbActionCtx (host/origin name+port, isDirect). Drop the unused
pid field; inline getpid() at the call site.
4. wolfSSH_AGENT_DefaultActions and wolfSSH_FwdDefaultActions now take
a WS_AppCtx* and reach feature-specific state via
appCtx->privateData. echoserver_test() is updated to register the
WS_AppCtx (not the old CbCtx) with wolfSSH_set_agent_cb_ctx and
wolfSSH_SetFwdCbCtx.
5. Reindent ssh_worker()'s #ifdef blocks and add /* WOLFSSH_xxx */
markers.
6. fwd.test.expect: redirect echoserver and portfwd output to log files
and sync on portfwd's -R ready file instead of matching "sampled" in
the pty. Under --enable-debug the WLOG volume fills the pty and
stalls portfwd in select() before channel-open.
1. Add a test script and expect script for testing forwarding.
2. Update portfwd to have a ready file option.
3. Fix echoserver error string, needed NL.
Simulate netowrk latency using netem and use it to test the non-blocking
mode of SFTP. This helps find issues which would affect running an SFTP
server on a microcontroller. It helped find the bug fixed in #876.
The autogen script is doing too many things. The tests that are set up
in the git hooks are already tested by GitHub with actions on branch
push. Also they don't work if you install wolfSSL somewhere specific.
All one needs to do is run `autoreconf -ivf` to make the configure
script. This is all autogen does now, with the addition of warnings.
1. Update scp.test to delete the empty test file.
2. In wolfSSHd, when coverting an IP address to a printable
representation, the destination needs to be able to handle IPv6
addresses potentially.
1. Added some command line options to the wolfSFTP client to show how to
use a hardcoded automatic file transfer rather than using the command
shell. On top of that, added a script to get and put some sample files.
It was built into the wolfSFTP client to allow for using all forms of
authentication as well as using the command line password.
2. Update wolfSSH_SFTP_STAT() with clearing the error register if it is WANT_READ.
1. Add enable options for "all" and "distro". all enables all options.
distro enables all and turns on both shared and static library builds.
2. Updated the commit-tests script to perform a check on enable-all as well.
3. Made a few syntactical changes to commit-tests.
