2024-01-25fs/hugetlbfs/inode.c: mm/memory-failure.c: fix hugetlbfs hwpoison handlingSidhartha Kumar
has_extra_refcount() makes the assumption that the page cache adds a ref count of 1 and subtracts this in the extra_pins case. Commit a08c7193e4f1 (mm/filemap: remove hugetlb special casing in filemap.c) modifies __filemap_add_folio() by calling folio_ref_add(folio, nr); for all cases (including hugtetlb) where nr is the number of pages in the folio. We should adjust the number of references coming from the page cache by subtracing the number of pages rather than 1. In hugetlbfs_read_iter(), folio_test_has_hwpoisoned() is testing the wrong flag as, in the hugetlb case, memory-failure code calls folio_test_set_hwpoison() to indicate poison. folio_test_hwpoison() is the correct function to test for that flag. After these fixes, the hugetlb hwpoison read selftest passes all cases.

2024-01-25readahead: avoid multiple marked readahead pagesJan Kara
ra_alloc_folio() marks a page that should trigger next round of async readahead. However it rounds up computed index to the order of page being allocated. This can however lead to multiple consecutive pages being marked with readahead flag. Consider situation with index == 1, mark == 1, order == 0. We insert order 0 page at index 1 and mark it. Then we bump order to 1, index to 2, mark (still == 1) is rounded up to 2 so page at index 2 is marked as well. Then we bump order to 2, index is incremented to 4, mark gets rounded to 4 so page at index 4 is marked as well. The fact that multiple pages get marked within a single readahead window confuses the readahead logic and results in readahead window being trimmed back to 1. This situation is triggered in particular when maximum readahead window size is not a power of two (in the observed case it was 768 KB) and as a result sequential read throughput suffers. Fix the problem by rounding 'mark' down instead of up. Because the index is naturally aligned to 'order', we are guaranteed 'rounded mark' == index iff 'mark' is within the page we are allocating at 'index' and thus exactly one page is marked with readahead flag as required by the readahead code and sequential read performance is restored. This effectively reverts part of commit b9ff43dd2743 ("mm/readahead: Fix readahead with large folios"). The commit changed the rounding with the rationale: "... we were setting the readahead flag on the folio which contains the last byte read from the block. This is wrong because we will trigger readahead at the end of the read without waiting to see if a subsequent read is going to use the pages we just read." Although this is true, the fact is this was always the case with read sizes not aligned to folio boundaries and large folios in the page cache just make the situation more obvious (and frequent). Also for sequential read workloads it is better to trigger the readahead earlier rather than later. It is true that the difference in the rounding and thus earlier triggering of the readahead can result in reading more for semi-random workloads. However workloads really suffering from this seem to be rare. In particular I have verified that the workload described in commit b9ff43dd2743 ("mm/readahead: Fix readahead with large folios") of reading random 100k blocks from a file like: [reader] bs=100k rw=randread numjobs=1 size=64g runtime=60s is not impacted by the rounding change and achieves ~70MB/s in both cases.

2024-01-25bpf: Fix error checks against bpf_get_btf_vmlinux().Kui-Feng Lee
In bpf_struct_ops_map_alloc, it needs to check for NULL in the returned pointer of bpf_get_btf_vmlinux() when CONFIG_DEBUG_INFO_BTF is not set. ENOTSUPP is used to preserve the same behavior before the struct_ops kmod support. In the function check_struct_ops_btf_id(), instead of redoing the bpf_get_btf_vmlinux() that has already been done in syscall.c, the fix here is to check for prog->aux->attach_btf_id. BPF_PROG_TYPE_STRUCT_OPS must require attach_btf_id and syscall.c guarantees a valid attach_btf as long as attach_btf_id is set. When attach_btf_id is not set, this patch returns -ENOTSUPP because it is what the selftest in test_libbpf_probe_prog_types() and libbpf_probes.c are expecting for feature probing purpose.

2024-01-26drm/sched: Drain all entities in DRM sched run job workerMatthew Brost
All entities must be drained in the DRM scheduler run job worker to avoid the following case. An entity found that is ready, no job found ready on entity, and run job worker goes idle with other entities + jobs ready. Draining all ready entities (i.e. loop over all ready entities) in the run job worker ensures all job that are ready will be scheduled.

2024-01-25nfp: flower: fix hardware offload for the transfer layer portHui Zhou
The nfp driver will merge the tp source port and tp destination port into one dword which the offset must be zero to do hardware offload. However, the mangle action for the tp source port and tp destination port is separated for tc ct action. Modify the mangle action for the FLOW_ACT_MANGLE_HDR_TYPE_TCP and FLOW_ACT_MANGLE_HDR_TYPE_UDP to satisfy the nfp driver offload check for the tp port. The mangle action provides a 4B value for source, and a 4B value for the destination, but only 2B of each contains the useful information. For offload the 2B of each is combined into a single 4B word. Since the incoming mask for the source is '0xFFFF<mask>' the shift-left will throw away the 0xFFFF part. When this gets combined together in the offload it will clear the destination field. Fix this by setting the lower bits back to 0xFFFF, effectively doing a rotate-left operation on the mask.

2024-01-25nfp: flower: add hardware offload check for post ct entryHui Zhou
The nfp offload flow pay will not allocate a mask id when the out port is openvswitch internal port. This is because these flows are used to configure the pre_tun table and are never actually send to the firmware as an add-flow message. When a tc rule which action contains ct and the post ct entry's out port is openvswitch internal port, the merge offload flow pay with the wrong mask id of 0 will be send to the firmware. Actually, the nfp can not support hardware offload for this situation, so return EOPNOTSUPP.

The first patch addresses the main problem I observe locally - the XDP program required by such tests, xdp_dummy, is currently build in the ebpf self-tests directory, not available if/when the user targets net only. Arguably is more a refactor than a fix, but still targeting net to hopefully The second patch fixes the integration of such tests with the build system.
