2022-09-28net: drop the weight argument from netif_napi_addJakub Kicinski
We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

2022-09-28net: Fix incorrect address comparison when searching for a bind2 bucketMartin KaFai Lau
The v6_rcv_saddr and rcv_saddr are inside a union in the 'struct inet_bind2_bucket'. When searching a bucket by following the bhash2 hashtable chain, eg. inet_bind2_bucket_match, it is only using the sk->sk_family and there is no way to check if the inet_bind2_bucket has a v6 or v4 address in the union. This leads to an uninit-value KMSAN report in [0] and also potentially incorrect matches. This patch fixes it by adding a family member to the inet_bind2_bucket and then tests 'sk->sk_family != tb->family' before matching the sk's address to the tb's address.

2022-09-29linux/export: use inline assembler to populate symbol CRCsMasahiro Yamada
Since commit 7b4537199a4a ("kbuild: link symbol CRCs at final link, removing CONFIG_MODULE_REL_CRCS"), the module versioning on the (non-upstreamed-yet) kvx Linux port is broken due to unexpected padding for __crc_* symbols. The kvx GCC adds padding so u32 gets 8-byte alignment instead of 4. I do not know if this happens for upstream architectures in general, but any compiler has the freedom to insert padding for faster access. Use the inline assembler to directly specify the wanted data layout. This is how we previously did before the breakage.

2022-09-28ata: libata-sata: Fix device queue depth controlDamien Le Moal
The function __ata_change_queue_depth() uses the helper ata_scsi_find_dev() to get the ata_device structure of a scsi device and set that device maximum queue depth. However, when the ata device is managed by libsas, ata_scsi_find_dev() returns NULL, turning __ata_change_queue_depth() into a nop, which prevents the user from setting the maximum queue depth of ATA devices used with libsas based HBAs. Fix this by renaming __ata_change_queue_depth() to ata_change_queue_depth() and adding a pointer to the ata_device structure of the target device as argument. This pointer is provided by ata_scsi_change_queue_depth() using ata_scsi_find_dev() in the case of a libata managed device and by sas_change_queue_depth() using sas_to_ata_dev() in the case of a libsas managed ata device.

2022-09-28powerpc/pseries: block untrusted device tree changes when locked downNathan Lynch
The /proc/powerpc/ofdt interface allows the root user to freely alter the in-kernel device tree, enabling arbitrary physical address writes via drivers that could bind to malicious device nodes, thus making it possible to disable lockdown. Historically this interface has been used on the pseries platform to facilitate the runtime addition and removal of processor, memory, and device resources (aka Dynamic Logical Partitioning or DLPAR). Years ago, the processor and memory use cases were migrated to designs that happen to be lockdown-friendly: device tree updates are communicated directly to the kernel from firmware without passing through untrusted user space. I/O device DLPAR via the "drmgr" command in powerpc-utils remains the sole legitimate user of /proc/powerpc/ofdt, but it is already broken in lockdown since it uses /dev/mem to allocate argument buffers for the rtas syscall. So only illegitimate uses of the interface should see a behavior change when running on a locked down kernel.

Use the new sample_flags to indicate whether the raw data field is filled by the PMU driver. Although it could check with the NULL, follow the same rule with other fields. Remove the raw field from the perf_sample_data_init() to minimize the number of cache lines touched.

2022-09-27RDMA/mlx5: Don't set tx affinity when lag is in hash modeLiu, Changcheng
In hash mode, without setting tx affinity explicitly, the port select flow table decides which port is used for the traffic. If port_select_flow_table_bypass capability is supported and tx affinity is set explicitly for QP/TIS, they will be added into the explicit affinity table in FW to check which port is used for the traffic. 1. The overloaded explicit affinity table may affect performance. To avoid this, do not set tx affinity explicitly by default. 2. The packets of the same flow need to be transmitted on the same port. Because the packets of the same flow use different QPs in slow & fast path, it shouldn't set tx affinity explicitly for these QPs.

In include/uapi/rdma/rdma_user_rxe.h there are redundant copies of num_sge in the rxe_send_wr, rxe_recv_wqe, and rxe_dma_info. Only the ones in rxe_dma_info are actually used by the rxe kernel driver. The userspace would set these values, but the kernel never read them. This change has no affect on the current ABI and new or old versions of rdma-core operate correctly with new or old versions of the kernel rxe driver.

This is modeled after the similar EFA enablement in commit 66f4817b5712 ("RDMA/efa: Add support for dmabuf memory regions"). Like EFA there is no support for revocation so we simply call the ib_umem_dmabuf_get_pinned() to obtain a umem instead of the normal ib_umem_get(). Everything else stays the same.
