2022-06-30RDMA/rxe: Fix deadlock in rxe_do_local_ops()Bob Pearson
When a local operation (invalidate mr, reg mr, bind mw) is finished there will be no ack packet coming from a responder to cause the wqe to be completed. This may happen anyway if a subsequent wqe performs IO. Currently if the wqe is signalled the completer tasklet is scheduled immediately but not otherwise. This leads to a deadlock if the next wqe has the fence bit set in send flags and the operation is not signalled. This patch removes the condition that the wqe must be signalled in order to schedule the completer tasklet which is the simplest fix for this deadlock and is fairly low cost. This is the analog for local operations of always setting the ackreq bit in all last or only request packets even if the operation is not signalled.

2022-06-30RDMA/rxe: Stop lookup of partially built objectsBob Pearson
Currently the rdma_rxe driver has a security weakness due to giving objects which are partially initialized indices allowing external actors to gain access to them by sending packets which refer to their index (e.g. qpn, rkey, etc) causing unpredictable results. This patch adds a new API rxe_finalize(obj) which enables looking up pool objects from indices using rxe_pool_get_index() for AH, QP, MR, and MW. They are added in create verbs only after the objects are fully initialized. It also adds wait for completion to destroy/dealloc verbs to assure that all references have been dropped before returning to rdma_core by implementing a new rxe_pool API rxe_cleanup() which drops a reference to the object and then waits for all other references to be dropped. When the last reference is dropped the object is completed by kref. After that it cleans up the object and if locally allocated frees the memory. In the special case of address handle objects the delay is implemented separately if the destroy_ah call is not sleepable. Combined with deferring cleanup code to type specific cleanup routines this allows all pending activity referring to objects to complete before returning to rdma_core.

2022-06-16Merge branch 'mlx5-next' into wip/leon-for-nextLeon Romanovsky
This merge commit includes shared updates to net-next and rdma-next for upcoming mlx5 features. 1) Updated HW bits and definitions for upcoming features 1.1) vport debug counters 1.2) flow meter 1.3) Execute ASO action for flow entry 1.4) enhanced CQE compression 2) Add ICM header-modify-pattern RDMA API Leon Says ========= SW steering manipulates packet's header using "modifying header" actions. Many of these actions do the same operation, but use different data each time. Currently we create and keep every one of these actions, which use expensive and limited resources. Now we introduce a new mechanism - pattern and argument, which splits a modifying action into two parts: 1. action pattern: contains the operations to be applied on packet's header, mainly set/add/copy of fields in the packet 2. action data/argument: contains the data to be used by each operation in the pattern. This way we reuse same patterns with different arguments to create new modifying actions, and since many actions share the same operations, we end up creating a small number of patterns that we keep in a dedicated cache. These modify header patterns are implemented as new type of ICM memory, so the following kernel patch series add the support for this new ICM type. ========== Link: https://lore.kernel.org/all/20220614184028.51548-1-saeed@kernel.org Signed-off-by: Leon Romanovsky <leon@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux Pull hardware timestamping subsystem from Thierry Reding: "This contains the new HTE (hardware timestamping engine) subsystem that has been in the works for a couple of months now. The infrastructure provided allows for drivers to register as hardware timestamp providers, while consumers will be able to request events that they are interested in (such as GPIOs and IRQs) to be timestamped by the hardware providers. Note that this currently supports only one provider, but there seems to be enough interest in this functionality and we expect to see more drivers added once this is merged" [ Linus Walleij mentions the Intel PMC in the Elkhart and Tiger Lake platforms as another future timestamp provider ] * tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: dt-bindings: timestamp: Correct id path dt-bindings: Renamed hte directory to timestamp hte: Uninitialized variable in hte_ts_get() hte: Fix off by one in hte_push_ts_ns() hte: Fix possible use-after-free in tegra_hte_test_remove() hte: Remove unused including <linux/version.h> MAINTAINERS: Add HTE Subsystem hte: Add Tegra HTE test driver tools: gpio: Add new hardware clock type gpiolib: cdev: Add hardware timestamp clock type gpio: tegra186: Add HTE support gpiolib: Add HTE support dt-bindings: Add HTE bindings hte: Add Tegra194 HTE kernel provider drivers: Add hardware timestamp engine (HTE) subsystem Documentation: Add HTE subsystem guide
