If an SSH proxy socket is frozen for long enough, and the SSH server
continues to send, then sooner or later the proxy SSH connection will
end up having to freeze its underlying physical socket too. When the
proxy socket is later unfrozen, it needs to pass that unfreezing on in
turn.
The way this should happen is that when the SshProxy begins to clear
the backlog of data passed to it from the proxy SSH connection via
seat_stdout, it should call backend_unthrottle to inform that proxy
connection that the backlog is clearing.
But there was no backlog_unthrottle call in the whole of sshproxy.c.
Now there is.
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
The PuTTY home web site is

If you want to send bug reports or feature requests, please read the
Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
