The device is got by isert_device_get() with refcount is 1, and is assigned to isert_conn by isert_conn->device = device. When isert_create_qp() failed, device will be freed with isert_device_put(). Later, the device is used in isert_free_login_buf(isert_conn) by the isert_conn->device->ib_device statement. Free the device in the correct order.

So move the device to error state and dispatch fatal events to all qps Release the MSIx vectors to avoid a crash when L2 driver disables the MSIx. Also, check for the device state to avoid posting further commands to the HW.

Current code uses many different types when dealing with a port of a RDMA device: u8, unsigned int and u32. Switch to u32 to clean up the logic. This allows us to make (at least) the core view consistent and use the same type. Unfortunately not all places can be converted. Many uverbs functions expect port to be u8 so keep those places in order not to break UAPIs. HW/Spec defined values must also not be changed. With the switch to u32 we now can support devices with more than 255 ports. U32_MAX is reserved to make control logic a bit easier to deal with. As a device with U32_MAX ports probably isn't going to happen any time soon this seems like a non issue. When a device with more than 255 ports is created uverbs will report the RDMA device as having 255 ports as this is the max currently supported. The verbs interface is not changed yet because the IBTA spec limits the port size in too many places to be u8 and all applications that relies in verbs won't be able to cope with this change. At this stage, we are extending the interfaces that are using vendor channel solely Once the limitation is lifted mlx5 in switchdev mode will be able to have thousands of SFs created by the device. As the only instance of an RDMA device that reports more than 255 ports will be a representor device and it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other ULPs aren't effected by this change and their sysfs/interfaces that are exposes to userspace can remain unchanged.

There is no need to create the ODP EQ if the user doesn't use ODP MRs. Hence, create it only when the first ODP MR is created. This EQ will be destroyed only when the device is unloaded. This will decrease the number of EQs created per device. for example: If we creates 1K devices (SF/VF/etc'), than we will decrease the num of EQs by 1K.

The umem DMA list calculation was locked at 4k pages due to confusion around how this API works and is used when larger pages are present. The conclusion is: - umem's cannot extend past what is mapped into the process, so creating a lage page size and referring to a sub-range is not allowed - umem's must always have a page offset of zero, except for sub PAGE_SIZE umems - The feature of umem_offset to create multiple objects inside a umem is buggy and isn't used anyplace. Thus we can assume all users of the current API have umem_offset == 0 as well Provide a new page size calculator that limits the DMA list to the VA range and enforces umem_offset == 0. Allow user space to specify the page sizes which it can accept, this bitmap must be derived from the intended use of the umem, based on per-usage HW limitations.

Change uverbs_get_const/uverbs_get_const_default to work properly with both signed/unsigned parameters. Current APIs mix s64 and u64 which leads to incorrect check when u64 value was supplied and its upper bit was set. In that case uverbs_get_const() / uverbs_get_const_default() lower bound check may fail unexpectedly, target is unsigned (lower bound is 0) but value became negative as of the s64 usage. Split to have two different APIs, no change to callers as the required API will be called internally according to the target type.

Now that the SRCU stuff has been removed the entire MR destroy logic can be made a lot simpler. Currently there are many different ways to destroy a MR and it makes it really hard to do this task correctly. Route all destruction through mlx5_ib_dereg_mr() and make it work for all situations. Since it turns out all the different MR types do basically the same thing this removes a lot of knowledge of MR internals from ODP and leaves ODP just exporting an operation to clean up children. This fixes a few weird corner cases bugs and firmly uses the correct ordering of the MR destruction: - Stop parallel access to the mkey via the ODP xarray - Stop DMA - Release the umem - Clean up ODP children - Free/Recycle the MR Link: https://lore.kernel.org/r/20210304120745.1090751-4-leon@kernel.orgSigned-off-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

The struct mlx5_ib_mr can be used for three different things, but only one at a time: - In the user MR cache - As a kernel MR - As a user MR Overlay the three things into a single union with the following rules: - If the mr is found on the cache_ent->head list then it is a cache MR and umem == NULL. The entire union is zero after the MR is removed from the cache. - If umem != NULL or type == IB_MR_TYPE_USER then it is a user MR. - If umem == NULL then it is a kernel MR This reduces the size of struct mlx5_ib_mr to 552 bytes from 702. The only place the three flows overlap in the code is during dereg, so add a few extra checks along there.

All of the ODP code assumes when it calls mlx5_mr_cache_alloc() the ODP related fields are zero'd. This is true if the MR was just allocated, but if the MR is recycled through the cache then the values are never zero'd. This causes a bug in the odp_stats, they don't reset when the MR is reallocated, also is_odp_implicit is never 0'd. So we can use memset on a block of the mlx5_ib_mr reorganize the structure to put all the data that can be zero'd by the cache at the end. It is organized as an anonymous struct because the next patch will make this a union. Delete the unused smr_info. Don't set the kernel only desc_size on the user path. No longer any need to zero mr->parent before freeing it, the memset() will get it now.
