H A Dsyscalls.master1.306 Fri Aug 14 00:53:16 GMT 2020 riastradh branches: 1.306.2;
New system call getrandom() compatible with Linux and others.

Three ways to call:

getrandom(p, n, 0) Blocks at boot until full entropy.
Returns up to n bytes at p; guarantees
up to 256 bytes even if interrupted
after blocking. getrandom(0,0,0)
serves as an entropy barrier: return
only after system has full entropy.

getrandom(p, n, GRND_INSECURE) Never blocks. Guarantees up to 256
bytes even if interrupted. Equivalent
to /dev/urandom. Safe only after
successful getrandom(...,0),
getrandom(...,GRND_RANDOM), or read
from /dev/random.

getrandom(p, n, GRND_RANDOM) May block at any time. Returns up to n
bytes at p, but no guarantees about how
many -- may return as short as 1 byte.
Equivalent to /dev/random. Legacy.
Provided only for source compatibility
with Linux.

Can also use flags|GRND_NONBLOCK to fail with EWOULDBLOCK/EAGAIN
without producing any output instead of blocking.

- The combination GRND_INSECURE|GRND_NONBLOCK is the same as
GRND_INSECURE, since GRND_INSECURE never blocks anyway.

- The combinations GRND_INSECURE|GRND_RANDOM and
GRND_INSECURE|GRND_RANDOM|GRND_NONBLOCK are nonsensical and fail
with EINVAL.

As proposed on tech-userlevel, tech-crypto, tech-security, and
tech-kern, and subsequently adopted by core (minus the getentropy part
of the proposal, because other operating systems and participants in
the discussion couldn't come to an agreement about getentropy and
blocking semantics):

find.

The filesystem ones all call genfs_eopnotsupp - right now I am only
implementing the plumbing and we can implement fallocate and/or
fdiscard for files later.

The device ones call spec_fallocate (which is also genfs_eopnotsupp)
and spec_fdiscard, which dispatches to the device-level op.

The fifo ones all call vn_fifo_bypass, which also ends up being
EOPNOTSUPP.

merge the bouyer-socketcan branch to HEAD.

CAN stands for Controller Area Network, a broadcast network used
in automation and automotive fields. For example, the NMEA2000 standard
developped for marine devices uses a CAN network as the link layer.

This is an implementation of the linux socketcan API:
https://www.kernel.org/doc/Documentation/networking/can.txt
you can also see can(4).

This adds a new socket family (AF_CAN) and protocol (PF_CAN),
as well as the canconfig(8) utility, used to set timing parameter of
CAN hardware. Also inclued is a driver for the CAN controller
found in the allwinner A20 SoC (I tested it with an Olimex lime2 board,
connected with PIC18-based CAN devices).

There is also the canloop(4) pseudo-device, which allows to use
the socketcan API without CAN hardware.

At this time the CANFD part of the linux socketcan API is not implemented.
Error frames are not implemented either. But I could get the cansend and
canreceive utilities from the canutils package to build and run with minimal
changes. tcpudmp(8) can also be used to record frames, which can be
decoded with etherreal.
