Log:
MFC: sys/opencrypto/cryptodev.c 1.26
Fix bogus check. It was possible to panic the kernel by giving 0 length.
This is actually a local DoS, as every user can use /dev/crypto if there
is crypto hardware in the system and cryptodev.ko is loaded (or compiled
into the kernel).
Reported by: Mike Tancsa <mike@sentex.net>
Security: Local DoS on systems with crypto HW and with /dev/crypto available
