[Qemu-devel] [PATCH v2 10/13] qemu-char: minor mux chardev fixes

[Gerd Hoffmann]

mux failure path has a memory leak.  creating a mux chardev can't
fail though, so just assert() that instead of fixing an error path
which never ever runs anyway ...

Also fix bid being leaked while being at it.

Also plugs memory leak on error path.  Worth mentioning in commit
message.

Plugs a memory leak, which is a bit more than "drop pointless
allocation".

Yes, both options apply only with server=true (I double-checked).

Curiously, qemu_chr_open_socket_fd() puts "telnet" into chr->filename
regardless of server.

qemu_chr_open_socket() has

    if (!is_listen)
        is_waitconnect = 0;

Should this perhaps be

    if (!is_listen) {
        is_waitconnect = 0;
        is_telnet = 0;
    }

?

My commit message nitpicks aren't worth a respin.  Perhaps you want to
fix them in your tree.

I'm not sure I understand what you're saying.  I fixed them
in my tree while applying, and that's exactly what I said --
"applied all..fixed these".  What does not worth what?

Thanks,

I think 11/13 doesn't qualify for qemu-trivial. In any case, it does
seem correct, like the rest.

With the commit message fixups from Michael: series

I replied to 02/13 and 12/13, suggesting commit message fixes.  You may
have covered some of them already, I don't know.

The question I asked re 07/13 is outside the scope of this series, so
don't worry about that one.
