2021-08-25Merge branch '1GbE' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2021-08-24 Vinicius Costa Gomes says: This adds support for PCIe PTM (Precision Time Measurement) to the igc driver. PCIe PTM allows the NIC and Host clocks to be compared more precisely, improving the clock synchronization accuracy. Patch 1/4 reverts a commit that made pci_enable_ptm() private to the PCI subsystem, reverting makes it possible for it to be called from the drivers. Patch 2/4 adds the pcie_ptm_enabled() helper. Patch 3/4 calls pci_enable_ptm() from the igc driver. Patch 4/4 implements the PCIe PTM support. Exposing it via the .getcrosststamp() API implies that the time measurements are made synchronously with the ioctl(). The hardware was implemented so the most convenient way to retrieve that information would be asynchronously. So, to follow the expectations of the ioctl() we have to use less convenient ways, triggering an PCIe PTM dialog every time a ioctl() is received. Some questions are raised (also pointed out in the commit message): 1. Using convert_art_ns_to_tsc() is too x86 specific, there should be a common way to create a 'system_counterval_t' from a timestamp. 2. convert_art_ns_to_tsc() says that it should only be used when X86_FEATURE_TSC_KNOWN_FREQ is true, but during tests it works even when it returns false. Should that check be done? ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2021-08-25net-next: When a bond have a massive amount of VLANs with IPv6 addresses, ↵Gilad Naaman
performance of changing link state, attaching a VRF, changing an IPv6 address, etc. go down dramtically. The source of most of the slow down is the `dev_addr_lists.c` module, which mainatins a linked list of HW addresses. When using IPv6, this list grows for each IPv6 address added on a VLAN, since each IPv6 address has a multicast HW address associated with it. When performing any modification to the involved links, this list is traversed many times, often for nothing, all while holding the RTNL lock. Instead, this patch adds an auxilliary rbtree which cuts down traversal time significantly. Performance can be seen with the following script: #!/bin/bash ip netns del test || true 2>/dev/null ip netns add test echo 1 | ip netns exec test tee /proc/sys/net/ipv6/conf/all/keep_addr_on_down > /dev/null set -e ip -n test link add foo type veth peer name bar ip -n test link add b1 type bond ip -n test link add florp type vrf table 10 ip -n test link set bar master b1 ip -n test link set foo up ip -n test link set bar up ip -n test link set b1 up ip -n test link set florp up VLAN_COUNT=1500 BASE_DEV=b1 echo Creating vlans ip netns exec test time -p bash -c "for i in \$(seq 1 $VLAN_COUNT); do ip -n test link add link $BASE_DEV name foo.\$i type vlan id \$i; done" echo Bringing them up ip netns exec test time -p bash -c "for i in \$(seq 1 $VLAN_COUNT); do ip -n test link set foo.\$i up; done" echo Assiging IPv6 Addresses ip netns exec test time -p bash -c "for i in \$(seq 1 $VLAN_COUNT); do ip -n test address add dev foo.\$i 2000::\$i/64; done" echo Attaching to VRF ip netns exec test time -p bash -c "for i in \$(seq 1 $VLAN_COUNT); do ip -n test link set foo.\$i master florp; done" On an Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz machine, the performance before the patch is (truncated): Creating vlans real 108.35 Bringing them up real 4.96 Assiging IPv6 Addresses real 19.22 Attaching to VRF real 458.84 After the patch: Creating vlans real 5.59 Bringing them up real 5.07 Assiging IPv6 Addresses real 5.64 Attaching to VRF real 25.37 Cc: David S.

2021-08-24lib/scatterlist: Fix wrong update of orig_nentsMaor Gottlieb
orig_nents should represent the number of entries with pages, but __sg_alloc_table_from_pages sets orig_nents as the number of total entries in the table. This is wrong when the API is used for dynamic allocation where not all the table entries are mapped with pages. It wasn't observed until now, since RDMA umem who uses this API in the dynamic form doesn't use orig_nents implicit or explicit by the scatterlist APIs. Fix it by changing the append API to track the SG append table state and have an API to free the append table according to the total number of entries in the table. Now all APIs set orig_nents as number of enries with pages.

2021-08-24net: dsa: let drivers state that they need VLAN filtering while standaloneVladimir Oltean
As explained in commit e358bef7c392 ("net: dsa: Give drivers the chance to veto certain upper devices"), the hellcreek driver uses some tricks to comply with the network stack expectations: it enforces port separation in standalone mode using VLANs. For untagged traffic, bridging between ports is prevented by using different PVIDs, and for VLAN-tagged traffic, it never accepts 8021q uppers with the same VID on two ports, so packets with one VLAN cannot leak from one port to another. That is almost fine*, and has worked because hellcreek relied on an implicit behavior of the DSA core that was changed by the previous patch: the standalone ports declare the 'rx-vlan-filter' feature as 'on [fixed]'. Since most of the DSA drivers are actually VLAN-unaware in standalone mode, that feature was actually incorrectly reflecting the hardware/driver state, so there was a desire to fix it. This leaves the hellcreek driver in a situation where it has to explicitly request this behavior from the DSA framework. We configure the ports as follows: - Standalone: 'rx-vlan-filter' is on. An 8021q upper on top of a standalone hellcreek port will go through dsa_slave_vlan_rx_add_vid and will add a VLAN to the hardware tables, giving the driver the opportunity to refuse it through .port_prechangeupper. - Bridged with vlan_filtering=0: 'rx-vlan-filter' is off. An 8021q upper on top of a bridged hellcreek port will not go through dsa_slave_vlan_rx_add_vid, because there will not be any attempt to offload this VLAN. The driver already disables VLAN awareness, so that upper should receive the traffic it needs. - Bridged with vlan_filtering=1: 'rx-vlan-filter' is on. An 8021q upper on top of a bridged hellcreek port will call dsa_slave_vlan_rx_add_vid, and can again be vetoed through .port_prechangeupper. *It is not actually completely fine, because if I follow through correctly, we can have the following situation: ip link add br0 type bridge vlan_filtering 0 ip link set lan0 master br0 # lan0 now becomes VLAN-unaware ip link set lan0 nomaster # lan0 fails to become VLAN-aware again, therefore breaking isolation This patch fixes that corner case by extending the DSA core logic, based on this requested attribute, to change the VLAN awareness state of the switch (port) when it leaves the bridge.

Introduce TWT action frames parsing support to mac80211. Currently just individual TWT agreement are support in AP mode. Whenever the AP receives a TWT action frame from an associated client, after performing sanity checks, it will notify the underlay driver with requested parameters in order to check if they are supported and if there is enough room for a new agreement. The driver is expected to set the agreement result and report it to mac80211. Drivers supporting this have two new callbacks: - add_twt_setup (mandatory) - twt_teardown_request (optional) mac80211 will send an action frame reply according to the result reported by the driver.

2021-08-24mmc: core: Store pointer to bio_crypt_ctx in mmc_requestEric Biggers
Make 'struct mmc_request' contain a pointer to the request's 'struct bio_crypt_ctx' directly, instead of extracting a 32-bit DUN from it which is a cqhci-crypto specific detail. This keeps the cqhci crypto specific details in the cqhci module, and it makes mmc_core and mmc_block ready for MMC crypto hardware that accepts the DUN and/or key in a way that is more flexible than that which will be specified by the eMMC v5.2 standard. Exynos SoCs are an example of such hardware, as their inline encryption hardware takes keys directly (it has no concept of keyslots) and supports 128-bit DUNs. Note that the 32-bit DUN length specified by the standard is very restrictive, so it is likely that more hardware will support longer DUNs despite it not following the standard. Thus, limiting the scope of the 32-bit DUN assumption to the place that actually needs it is warranted.

2021-08-23bpf: Migrate cgroup_bpf to internal cgroup_bpf_attach_type enumDave Marchevsky
Add an enum (cgroup_bpf_attach_type) containing only valid cgroup_bpf attach types and a function to map bpf_attach_type values to the new enum. Inspired by netns_bpf_attach_type. Then, migrate cgroup_bpf to use cgroup_bpf_attach_type wherever possible. Functionality is unchanged as attach_type_to_prog_type switches in bpf/syscall.c were preventing non-cgroup programs from making use of the invalid cgroup_bpf array slots. As a result struct cgroup_bpf uses 504 fewer bytes relative to when its arrays were sized using MAX_BPF_ATTACH_TYPE. bpf_cgroup_storage is notably not migrated as struct bpf_cgroup_storage_key is part of uapi and contains a bpf_attach_type member which is not meant to be opaque. Similarly, bpf_cgroup_link continues to report its bpf_attach_type member to userspace via fdinfo and bpf_link_info. To ease disambiguation, bpf_attach_type variables are renamed from 'type' to 'atype' when changed to cgroup_bpf_attach_type.

2021-08-23io_uring: add support for IORING_OP_LINKATDmitry Kadashev
IORING_OP_LINKAT behaves like linkat(2) and takes the same flags and arguments. In some internal places 'hardlink' is used instead of 'link' to avoid confusion with the SQE links. Name 'link' conflicts with the existing 'link' member of io_kiocb.

2021-08-23bio: add allocation cache abstractionJens Axboe
Add a per-cpu bio_set cache for bio allocations, enabling us to quickly recycle them instead of going through the slab allocator. This cache isn't IRQ safe, and hence is only really suitable for polled IO. Very simple - keeps a count of bio's in the cache, and maintains a max of 512 with a slack of 64. If we get above max + slack, we drop slack number of bio's. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-08-23fs: add kiocb alloc cache flagJens Axboe
