Mellanox INNOVA IPsec cards are EOL in Nov, 2019 [1]. As such, the code is unmaintained, untested and not in-use by any upstream/distro oriented customers. In order to reduce code complexity, drop the kernel code.

2021-08-09net/mlx5: Synchronize correct IRQ when destroying CQShay Drory1-3/+1
The CQ destroy is performed based on the IRQ number that is stored in cq->irqn. That number wasn't set explicitly during CQ creation and as expected some of the API users of mlx5_core_create_cq() forgot to update it. This caused to wrong synchronization call of the wrong IRQ with a number 0 instead of the real one. As a fix, set the IRQ number directly in the mlx5_core_create_cq() and update all users accordingly.

2020-02-19net/mlx5e: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

This merge commit includes some misc shared code updates from mlx5-next branch needed for net-next. 1) From Aya: Enable general events on all physical link types and restrict general event handling of subtype DELAY_DROP_TIMEOUT in mlx5 rdma driver to ethernet links only as it was intended. 2) From Eli: Introduce low level bits for prio tag mode 3) From Maor: Low level steering updates to support RDMA RX flow steering and enables RoCE loopback traffic when switchdev is enabled. 4) From Vu and Parav: Two small mlx5 core cleanups 5) From Yevgeny add HW definitions of geneve offloads Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2019-04-29net/mlx5: Pass flow steering objects to fs_cmdMaor Gottlieb1-41/+45
Pass the flow steering objects instead of their attributes to fs_cmd in order to decrease number of arguments and in addition it will be used to update object fields. Pass the flow steering root namespace instead of the device so will have context to the namespace in the fs_cmd layer.

Linux 5.1-rc1 We forgot to reset the branch last merge window thus mlx5-next is outdated and still based on 5.0-rc2. This merge commit is needed to sync mlx5-next branch with 5.1-rc1. Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2019-04-09net/mlx5: FPGA, tls, idr remove on flow deleteSaeed Mahameed1-28/+15
Flow is kfreed on mlx5_fpga_tls_del_flow but kept in the idr data structure, this is risky and can cause use-after-free, since the idr_remove is delayed until tls_send_teardown_cmd completion. Instead of delaying idr_remove, in this patch we do it on mlx5_fpga_tls_del_flow, before actually kfree(flow). Added synchronize_rcu before kfree(flow) Fixes: ab412e1dd7db ("net/mlx5: Accel, add TLS rx offload routines") Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
