[PATCH rdma-next v1 0/7] Preparation to DevX extension series

[PATCH rdma-next v1 0/7] Preparation to DevX extension series

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Changelog v0->v1:
 * Update commit messages
 * Split DevX series to small sub-series.
 * Change static initialization from {0} to be {}

------- From Yishai,

Set uid as part of various IB commands so that the firmware can manage
the IB object in a secured way.

The firmware should mark this IB object with the given uid so that it
can be used later on only by objects with the same uid.

Upon DEVX flows that use this objec, the pointed object must have
the same uid as of the issuer uid command.

When a command is issued with uid=0 it means that the issuer of the
command is trusted (i.e. kernel), in that case any pointed object
can be used regardless of its uid.

Thanks

[PATCH mlx5-next v1 1/7] net/mlx5: Set uid as part of CQ commands

[Leon Romanovsky]

From: Yishai Hadas <yishaih@mellanox.com>

Set uid as part of CQ commands so that the firmware can manage the CQ
object in a secured way.

The firmware should mark this CQ with the given uid so that it can
be used later on only by objects with the same uid.

Upon DEVX flows that use this CQ (e.g. create QP command), the
pointed CQ must have the same uid as of the issuer uid command.

When a command is issued with uid=0 it means that the issuer of the
command is trusted (i.e. kernel), in that case any pointed object
can be used regardless of its uid.

[PATCH mlx5-next v1 4/7] net/mlx5: Set uid as part of SQ commands

[Leon Romanovsky]

From: Yishai Hadas <yishaih@mellanox.com>

Set uid as part of SQ commands so that the firmware can manage the
SQ object in a secured way.

That will enable using an SQ that was created by verbs application
to be used by the DEVX flow in case the uid is equal.

[PATCH mlx5-next v1 6/7] net/mlx5: Set uid as part of DCT commands

[Leon Romanovsky]

From: Yishai Hadas <yishaih@mellanox.com>

Set uid as part of DCT commands so that the firmware can manage the
DCT object in a secured way.

That will enable using a DCT that was created by verbs application
to be used by the DEVX flow in case the uid is equal.

Re: [PATCH mlx5-next v1 7/7] net/mlx5: Update mlx5_ifc with DEVX UID bits

typo - TRI --> TIR

"DEVX information" is a bit cryptic - what does xxx_valid means
for the devx use case (fw command is issued by devx process) - and
what semantics does it have for non-devx callers -- e.g the Eth driver when
they deal with tir/tis/etc

Explain and elaborate further at the change log

Or.

This series deals with FS core and commands used by the Ethernet driver

such as the life-cycle (create, modify, destroy) of objects like:
RQ/SQ/CQ/etc --
saying IB commands is inaccurate, please be more precise

these are not IB objects, but rather Ethernet objects

This and the next series look OK to me. Let me know when it is applied
to the mlx branch
