Jakub Kicinski says: ==================== net/tls: add ctrl path tracing and statistics This set adds trace events related to TLS offload and basic MIB stats for TLS. First patch contains the TLS offload related trace points. Those are helpful in troubleshooting offload issues, especially around the resync paths. Second patch adds a tracepoint to the fastpath of device offload, it's separated out in case there will be objections to adding fast path tracepoints. Again, it's quite useful for debugging offload issues. Next four patches add MIB statistics. The statistics are implemented as per-cpu per-netns counters. Since there are currently no fast path statistics we could move to atomic variables. Per-CPU seem more common. Most basic statistics are number of created and live sessions, broken out to offloaded and non-offloaded. Users seem to like those a lot. Next there is a statistic for decryption errors. These are primarily useful for device offload debug, in normal deployments decryption errors should not be common. Last but not least a counter for device RX resync. ==================== Reviewed-by: Simon Horman <simon.horman@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
