riastradh | ualea(4): Enter the data under the softc lock.
This avoids a race with a concurrent ualea_get updating sc_needed,
which could lead to hang when requesting more entropy.
ualea(4) now survives
sysctl -w kern.entropy.depletion=1
cat </dev/random >/dev/null &
cat </dev/random >/dev/null &
without hanging for longer (even if yanked and reinserted in the
middle, although the detach path is not relevant to the bug this
change fixes).

riastradh | ualea(4): Simplify xfer error branches.
- Avoid going into a loop in case the transfer fails repeatedly --
just give up immediately if it fails.
- Assert result size is reasonable; no need to assume usbdi(9) is
malicious. If it can return ux_actlen > ux_length, that's a bug in
usbdi(9) that we should fix.

| 20-Mar-2022 |
riastradh | ualea(4): Fix detach and error paths.
- Set sc_needed before aborting the pipe to prevent the xfer callback
from rescheduling itself.
- Make sure all paths out of the xfer callback clear sc_inflight.
While here, use device_printf instead of aprint_* after attach.
Now my system survives repeated insertion and yanking of ualea(4)
during:
sysctl -w kern.entropy.depletion=1
cat </dev/random >/dev/null
|
| 1.16 |
| 19-Mar-2022 |
riastradh | rnd(9): Adjust IPL of locks used by rndsource callbacks.
These no longer ever run from hard interrupt context or with a spin
lock held, so there is no longer any need to have them at IPL_VM to
block hard interrupts. Instead, lower them to IPL_SOFTSERIAL.

Prune dead branches as a result of this change.

Set up the USB xfer for every transfer, not just once in the attach
function. Caught by DIAGNOSTIC on a similar driver. Thanks to phone@
for USB xfer clue and martin@ for testing.

riastradh | rnd_attach_source calls the callback itself now.
No need for every driver to explicitly call it to prime the pool.
Eliminate now-unused <sys/rndpool.h>.

USBD_SHORT_XFER_OK as it has not bearing on number of TDs

Modularize ualea(4).
Unclear why we have a separate xyz.ioconf for module and XYZ.ioconf
for rump component, but at least xyz_modcmd obviates the need for
xyz_component.c (though evidently the latter could have been replaced
anyway by RUMP_COMPONENT=ioconf in the rump component Makefile).
|

| 18-Apr-2017 |
riastradh | gson@ informs me the Alea I and II have the same USB product id.
Thus, ualea(4) should work for both of them. Rename USB product id
ARANEUS ALEA_II to ARANEUS ALEA to reflect this.
No functional change intended, except perhaps via usbdevs.

riastradh | New rndsource driver for Araneus Alea II TRNG USB devices.
Disabled by default in x86/GENERIC and usbdevices.config pending
review and testing without rump ugenhc in the way, but enabled in
x86/ALL for compile-testing.
(Hi gson! Finally found a round tuit in my pocket, next to a certain
rectangular one.)
