Hello,
I've written a SHA1 driver for our custom HW running Linux 2.6.28.4.
The driver passed all the SHA1 tests but kept failing at hmac(sha1-hw) test 3.
During my debugging I added printk-s in the testmgr to also print successful tests. When I did that all the tests passed. All future encryption/decryptions (I set up a tunnel between the board and a server and ping-ed packets back and forth) were processed successfully by the driver.
Attached below the output of the testmgr when setting up the tunnel (my driver registers with name sha1-hw and is implemented by "hw_SHA" kernel module ) and of /proc/crypto.
Any ideas as to what could be the reason for the failure?
Thanks,
Avital
