Subject: blktest/rxe almost working
Date: Thu, 2 Sep 2021 16:41:15 -0500 [thread overview]
Message-ID: <c7557529-d07d-3e35-0f03-2bbe867af4a1@gmail.com> (raw)
Now that for-next is on 5.14.0-rc6+ blktest srp/002 is very close to working for rxe but there is
still one error. After adding MW support I added a test to local invalidate to check and see if the l/rkey matched the key actually contained in the MR/MW when local invalidate is called. This is failing
for srp/002 with the key portion of the rkey off by one. Looking at ib_srp.c I see code that does in fact
increment the rkey by one and also has code that posts a local invalidate. This was never checked before
and is now failing to match. If I mask off the key portion in the test the whole test case passes so
the other problems appear to have been fixed. If the increment and invalidate are out of sync this could
result in the error. I suspect this may be a bug in srp. Worst case I can remove this test but I would
rather not.
Bob
