Hi -
I have multi-process application in which primary process initializes all
crypto devices and sets up sessions. Secondary process uses the pre-initialized
devices and sessions.
It was working fine till DPDK 18.05. When switched to DPDK 18.11, secondary
process started giving seg fault on receive. Primary process can still send and
receive packets to/from crypto devices.
When switched to use HW crypto (QAT) instead of software crypto, same
application works fine on DPDK 18.11. Is the usage model correct? Anything
changed in DPDK 18.11 which might explain this?
Regards
Pravin
