2021-07-13net/uring: add probing capabilitykadmin2-0/+31
Adds the ability to probe for various capabilities. It will not call into C unless necessary. It also allocates one probe per call to new capability, which may be expensive, so in theory they could be reused instead. Signed-off-by: kadmin <julianknodt@gmail.com>

2021-07-13WIP: clean shutdown for UDP connJosh Bleecher Snyder2-29/+74
this appears to work, most of the time. there's lots of documentation work remaining, thinking through the structure remaining, testing remaining, porting to file remaining (if appropriate).

2021-07-13fix io_uring tun device readsJosh Bleecher Snyder2-10/+12
Well that's an interesting one! Apparently if you issue multiple concurrent preadv calls on a TUN device using io_uring, the TUN device falls over. Possibly corrupting memory along the way. Which might be why the kernel hung on shutdown...
