* Leave non-interactive at default QoS classMatt Johnston2022-01-271-8/+2
| | | | | | | | Lower class levels are less well defined, and non-interactive SSH can carry various different types of applications. This change also sets lowdelay class (AF21) earlier in an an outbound dbclient session
* Use DSCP for IP QoS traffic classesMatt Johnston2022-01-251-1/+1
| | | | | | | | | | | The previous TOS values are deprecated and not used by modern traffic classifiers. This sets AF21 for "interactive" traffic (with a tty). Non-tty traffic sets AF11 - that indicates high throughput but is not lowest priority (which would be CS1 or LE). This differs from the CS1 used by OpenSSH, it lets interactive git over SSH have higher priority than background least effort traffic. Dropbear's settings here should be suitable with the diffservs used by CAKE qdisc.
* Bring back recently removed channel->flushingMatt Johnston2021-10-141-2/+5
| | | | | This resolves the "sleep 10&echo hello" case which should return immediately
* Replace ChanType.sepfds with Channel.bidir_fdMatt Johnston2021-10-111-1/+3
| | | | | | | | This handles the case where a svrchansess has separate FDs for nopty, but a single FD for pty mode. The use of sepfds was also previously incorrect for X11 and agent forwarding
* - Remove "flushing" handling for exited processes, it should beMatt Johnston2021-10-111-2/+0

* Set tcp priority as follows:Matt Johnston2014-07-161-9/+9
| | | | | | | | if (connecting || ptys || x11) tos = LOWDELAY; else if (tcp_forwards) tos = 0; else tos = BULK; TCP forwards could be either lowdelay or bulk, hence the default priority.
