Rohit Maheshwari says: ==================== cxgb4/ch_ktls: Fixes in nic tls code This series helps in fixing multiple nic ktls issues. Series is broken into 12 patches. Patch 1 avoids deciding tls packet based on decrypted bit. If its a retransmit packet which has tls handshake and finish (for encryption), decrypted bit won't be set there, and so we can't rely on decrypted bit. Patch 2 helps supporting linear skb. SKBs were assumed non-linear. Corrected the length extraction. Patch 3 fixes the checksum offload update in WR. Patch 4 fixes kernel panic happening due to creating new skb for each record. As part of fix driver will use same skb to send out one tls record (partial data) of the same SKB. Patch 5 fixes the problem of skb data length smaller than remaining data of the record. Patch 6 fixes the handling of SKBs which has tls header alone pkt, but not starting from beginning. Patch 7 avoids sending extra data which is used to make a record 16 byte aligned. We don't need to retransmit those extra few bytes. Patch 8 handles the cases where retransmit packet has tls starting exchanges which are prior to tls start marker. Patch 9 fixes the problem os skb free before HW knows about tcp FIN. Patch 10 handles the small packet case which has partial TAG bytes only. HW can't handle those, hence using sw crypto for such pkts. Patch 11 corrects the potential tcb update problem. Patch 12 stops the queue if queue reaches threshold value. v1->v2: - Corrected fixes tag issue. - Marked chcr_ktls_sw_fallback() static. v2->v3: - Replaced GFP_KERNEL with GFP_ATOMIC. - Removed mixed fixes. v3->v4: - Corrected fixes tag issue. v4->v5: - Separated mixed fixes from patch 4. v5-v6: - Fixes tag should be at the end. ==================== Link: https://lore.kernel.org/r/20201109105142.15398-1-rohitm@chelsio.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
