In the mlx4_ib_post_send() flow, some functions call ib_get_cached_pkey() without checking its return value. If ib_get_cached_pkey() returns an error code, these functions should return failure. Fixes:1ffeb2eb8b("IB/mlx4: SR-IOV IB context objects and proxy/tunnel SQP support") Fixes:225c7b1fee("IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters") Fixes:e622f2f4ad("IB: split struct ib_send_wr") Link: https://lore.kernel.org/r/20200426075921.130074-1-leon@kernel.org Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.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.
