Indicate next PN update using update_pn flag in macsec_context. Offloaded MACsec implementations does not know whether or not the MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume that next PN should always updated, but this is not always true. The PN can be reset to its initial value using the following command: $ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case Or, the update PN command will succeed even if the driver does not support PN updates. $ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case Comparing the initial PN with the new PN value is not a solution. When the user updates the PN using its initial value the command will succeed, even if the driver does not support it. Like this: $ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \ ead3664f508eb06c40ac7104cdae4ce5 $ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case Signed-off-by: Radu Pirea (NXP OSS) <radu-nicolae.pirea@oss.nxp.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

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.
