Hi,
System calls should not fail due to temporary memory shortage in
malloc(9) or pool_get(9).
Pass down a wait flag to pru_attach(). During syscall socket(2)
it is ok to wait, this logic was missing for internet pcb. Pfkey
and route sockets were already waiting.
sonewconn() cannot wait when called during TCP 3-way handshake.
This logic has been preserved. Unix domain stream socket connect(2)
can wait until the other side has created the socket to accept.
ok?
