Implement the accept command by calling inet_accept. To avoid blocking
in the kernel, call inet_accept(O_NONBLOCK) from a workqueue, which get
scheduled on sk_data_ready (for a passive socket, it means that there
are connections to accept).
Use the reqcopy field to store the request. Accept the ne

We have one ioworker per socket. Each ioworker goes through the list of
outstanding read/write requests. Once all requests have been dealt with,
it returns.
We use one atomic counter per socket for "read" operations and one
for "write" operations to keep track of the reads/writes to do.

Release both active and passive sockets. For active sockets, make sure
to avoid possible conflicts with the ioworker reading/writing to those
sockets concurrently. Set map->release to let the ioworker know
atomically that the socket will be released soon, then wait until the

Hi all,
this series introduces the backend for the newly introduced PV Calls

PV Calls is a paravirtualized protocol that allows the implementation of
a set of POSIX functions in a different domain. The PV Calls frontend
sends POSIX function calls to the backend, which implements them an

mappass->reqcopy, and reply back when there is data on the passive

Poll on active socket is unimplemented as by the spec, as the frontend

I meant to shorten it from Altera Cyclone V to Altera FPGA.
Didn't quite make it.
