-Subject: dropbear: increase default receive window size
-
-Increasing the receive window size improves throughout on higher-latency
-links such as WAN connections. The current default of 24KB caps out at
-around 500 KB/s.
-
-Increasing the receive buffer to 256KB increases the throughput to at
-least 11 MB/s.

-Subject: netifd: system-linux: fix race condition in netlink socket error handing
-
-The error handling needed for the buffer growth logic relies on
-uloop_fd's error flag, which is set based on epoll events. Doing so
-without handling recvmsg's error codes is racy, as an error state may be
-set between receiving epoll events and the next recvmsg, but calling
-recvmsg clears the error state.
-
-To fix this, add handling for errors returned by nl_recvmsgs_default()
-and nl_recv(); checking for u->error and retrieving the error status
-using getsockopt() becomes redundant.
-
-We have observed this issue on Gluon (recent OpenWrt 23.05); on some
-devices with DSA switches, the bridge interface's carrier-on event would
-consistenly get lost during boot due to insufficient buffer space
-(see [1]).
-
-We have bisected the issue to netifd commit 516ab774cc16 ("system-linux:
-fix race condition on bringing up wireless devices"), but that commit only
-uncovered the preexisting bug by switching from getting the carrier state
-from sysfs to using the netlink messages in cb_rtnl_event().
-
-I suspect that other recent issues about netifd missing a carrier state
-change like [2] may have the same underlying cause.
