2023-02-06net/sched: move struct tc_mqprio_qopt_offload from pkt_cls.h to pkt_sched.hVladimir Oltean1-1/+1
Since mqprio is a scheduler and not a classifier, move its offload structure to pkt_sched.h, where struct tc_taprio_qopt_offload also lies. Also update some header inclusions in drivers that access this structure, to the best of my abilities.

2022-11-25ch_ktls: Use memcpy_from_page() instead of k[un]map_atomic()Anirudh Venkataramanan1-14/+12
kmap_atomic() is being deprecated in favor of kmap_local_page(). Replace the map-memcpy-unmap usage pattern (done using k[un]map_atomic()) with memcpy_from_page(), which internally uses kmap_local_page() and kunmap_local(). This renders the variables 'data' and 'vaddr' unnecessary, and so remove these too. Note that kmap_atomic() disables preemption and page-fault processing, but kmap_local_page() doesn't. When converting uses of kmap_atomic(), one has to check if the code being executed between the map/unmap implicitly depends on page-faults and/or preemption being disabled. If yes, then code to disable page-faults and/or preemption should also be added for functional correctness. That however doesn't appear to be the case here, so just memcpy_from_page() is used. Also note that the page being mapped is not allocated by the driver, and so the driver doesn't know if the page is in normal memory. This is the reason kmap_local_page() is used (via memcpy_from_page()) as opposed to page_address(). I don't have hardware, so this change has only been compile tested.

Commit 'c2ed5611afd7' has increased the cpl_t5_pass_accept_rpl{} structure size by 8B to avoid roundup. cpl_t5_pass_accept_rpl{} is a HW specific structure and increasing its size will lead to unwanted adapter errors. Current commit reverts the cpl_t5_pass_accept_rpl{} back to its original and allocates zeroed skb buffer there by avoiding the memset for iss field. Reorder code to minimize chip type checks.

2022-08-11net/tls: Use RCU API to access tls_ctx->netdevMaxim Mikityanskiy1-1/+7
Currently, tls_device_down synchronizes with tls_device_resync_rx using RCU, however, the pointer to netdev is stored using WRITE_ONCE and loaded using READ_ONCE. Although such approach is technically correct (rcu_dereference is essentially a READ_ONCE, and rcu_assign_pointer uses WRITE_ONCE to store NULL), using special RCU helpers for pointers is more valid, as it includes additional checks and might change the implementation transparently to the callers. Mark the netdev pointer as __rcu and use the correct RCU helpers to access it. For non-concurrent access pass the right conditions that guarantee safe access (locks taken, refcount value). Also use the correct helper in mlx5e, where even READ_ONCE was missing. The transition to RCU exposes existing issues, fixed by this commit: 1. bond_tls_device_xmit could read netdev twice, and it could become NULL the second time, after the NULL check passed. 2. Drivers shouldn't stop processing the last packet if tls_device_down just set netdev to NULL, before tls_dev_del was called. This prevents a possible packet drop when transitioning to the fallback software mode.

Pull rdma updates from Jason Gunthorpe: "Another small cycle. Mostly cleanups and bug fixes, quite a bit assisted from bots. There are a few new syzkaller splats that haven't been solved yet but they should get into the rcs in a few weeks, I think. Summary: - Update drivers to use common helpers for GUIDs, pkeys, bitmaps, memset_startat, and others - General code cleanups from bots - Simplify some of the rxe pool code in preparation for a larger rework - Clean out old stuff from hns, including all support for hip06 devices - Fix a bug where GID table entries could be missed if the table had holes in it - Rename paths and sessions in rtrs for better understandability - Consolidate the roce source port selection code - NDR speed support in mlx5" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (83 commits) RDMA/irdma: Remove the redundant return RDMA/rxe: Use the standard method to produce udp source port RDMA/irdma: Make the source udp port vary RDMA/hns: Replace get_udp_sport with rdma_get_udp_sport RDMA/core: Calculate UDP source port based on flow label or lqpn/rqpn IB/qib: Fix typos RDMA/rtrs-clt: Rename rtrs_clt to rtrs_clt_sess RDMA/rtrs-srv: Rename rtrs_srv to rtrs_srv_sess RDMA/rtrs-clt: Rename rtrs_clt_sess to rtrs_clt_path RDMA/rtrs-srv: Rename rtrs_srv_sess to rtrs_srv_path RDMA/rtrs: Rename rtrs_sess to rtrs_path RDMA/hns: Modify the hop num of HIP09 EQ to 1 IB/iser: Align coding style across driver IB/iser: Remove un-needed casting to/from void pointer IB/iser: Don't suppress send completions IB/iser: Rename ib_ret local variable IB/iser: Fix RNR errors IB/iser: Remove deprecated pi_guard module param IB/mlx5: Expose NDR speed through MAD RDMA/cxgb4: Set queue pair state when being queried ...
2022-01-12libcxgb: Don't accidentally set RTO_ONLINK in cxgb_find_route()Guillaume Nault1-1/+2
Mask the ECN bits before calling ip_route_output_ports(). The tos variable might be passed directly from an IPv4 header, so it may have the last ECN bit set. This interferes with the route lookup process as ip_route_output_key_hash() interpretes this bit specially (to restrict the route scope). Found by code inspection, compile tested only.

2022-01-10cxgb4vf: Remove useless DMA-32 fallback configurationChristophe JAILLET1-15/+5
As stated in [1], dma_set_mask() with a 64-bit mask never fails if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. So, if dma_set_mask_and_coherent() succeeds, 'pci_using_dac' is known to be 1. Simplify code and remove some dead code accordingly.

2022-01-02chelsio: cxgb: Use dma_set_mask_and_coherent() and simplify codeChristophe JAILLET1-15/+4
Use dma_set_mask_and_coherent() instead of unrolling it with some dma_set_mask()+dma_set_coherent_mask(). Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never fail if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. That said, 'pci_using_dac' can only be 1 after a successful dma_set_mask_and_coherent(). Simplify code and remove some dead code accordingly.

2021-12-15iw_cxgb4: Use memset_startat() for cpl_t5_pass_accept_rplKees Cook1-1/+1
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields. Use memset_startat() so memset() doesn't get confused about writing beyond the destination member that is intended to be the starting point of zeroing through the end of the struct. Additionally, since everything appears to perform a roundup (including allocation), just change the size of the struct itself and add a build-time check to validate the expected size.
