Subject: [PATCH net v2 0/2] ibmvnic: Bug fixes for queue descriptor processing
Date: Mon, 30 Nov 2020 13:07:22 -0600 [thread overview]
Message-ID: <1606763244-28111-1-git-send-email-tlfalcon@linux.ibm.com> (raw)
This series resolves a few issues in the ibmvnic driver's
RX buffer and TX completion processing. The first patch
includes memory barriers to synchronize queue descriptor
reads. The second patch fixes a memory leak that could
occur if the device returns a TX completion with an error
code in the descriptor, in which case the respective socket
buffer and other relevant data structures may not be freed
or updated properly.
v2: Provide more detailed comments explaining specifically what
reads are being ordered, suggested by Michael Ellerman
Thomas Falcon (2):
ibmvnic: Ensure that SCRQ entry reads are correctly ordered
ibmvnic: Fix TX completion error handling
