[PATCH RFC net-next v2 0/3] vsock: add support for sockmap

by Bobby Eshleman

Add support for sockmap to vsock. We're testing usage of vsock as a way to redirect guest-local UDS requests to the host and this patch series greatly improves the performance of such a setup. Compared to copying packets via userspace, this improves throughput by 121% in basic testing. Tested as follows. Setup: guest unix dgram sender -> guest vsock redirector -> host vsock server Threads: 1 Payload: 64k No sockmap: - 76.3 MB/s - The guest vsock redirector was "socat VSOCK-CONNECT:2:1234 UNIX-RECV:/path/to/sock" Using sockmap (this patch): - 168.8 MB/s (+121%) - The guest redirector was a simple sockmap echo server, redirecting unix ingress to vsock 2:1234 egress. - Same sender and server programs *Note: these numbers are from RFC v1 Only the virtio transport has been tested. The loopback transport was used in writing bpf/selftests, but not thoroughly tested otherwise. This series requires the skb patch. Changes in v2: - vsock/bpf: rename vsock_dgram_* -> vsock_* - vsock/bpf: change sk_psock_{get,put} and {lock,release}_sock() order to minimize slock hold time - vsock/bpf: use "new style" wait - vsock/bpf: fix bug in wait log - vsock/bpf: add check that recvmsg sk_type is one dgram, seqpacket, or stream. Return error if not one of the three. - virtio/vsock: comment __skb_recv_datagram() usage - virtio/vsock: do not init copied in read_skb() - vsock/bpf: add ifdef guard around struct proto in dgram_recvmsg() - selftests/bpf: add vsock loopback config for aarch64 - selftests/bpf: add vsock loopback config for s390x - selftests/bpf: remove vsock device from vmtest.sh qemu machine - selftests/bpf: remove CONFIG_VIRTIO_VSOCKETS=y from config.x86_64 - vsock/bpf: move transport-related (e.g., if (!vsk->transport)) checks out of fast path Signed-off-by: Bobby Eshleman <bobby.eshleman(a)bytedance.com> --- Bobby Eshleman (3): vsock: support sockmap selftests/bpf: add vsock to vmtest.sh selftests/bpf: Add a test case for vsock sockmap drivers/vhost/vsock.c | 1 + include/linux/virtio_vsock.h | 1 + include/net/af_vsock.h | 17 ++ net/vmw_vsock/Makefile | 1 + net/vmw_vsock/af_vsock.c | 55 ++++++- net/vmw_vsock/virtio_transport.c | 2 + net/vmw_vsock/virtio_transport_common.c | 24 +++ net/vmw_vsock/vsock_bpf.c | 175 +++++++++++++++++++++ net/vmw_vsock/vsock_loopback.c | 2 + tools/testing/selftests/bpf/config.aarch64 | 2 + tools/testing/selftests/bpf/config.s390x | 3 + tools/testing/selftests/bpf/config.x86_64 | 3 + .../selftests/bpf/prog_tests/sockmap_listen.c | 163 +++++++++++++++++++ 13 files changed, 443 insertions(+), 6 deletions(-) --- base-commit: d83115ce337a632f996e44c9f9e18cadfcf5a094 change-id: 20230118-support-vsock-sockmap-connectible-2e1297d2111a Best regards, -- Bobby Eshleman <bobby.eshleman(a)bytedance.com>

[net-next 0/3] seg6: add PSP flavor support for SRv6 End behavior

by Andrea Mayer

Segment Routing for IPv6 (SRv6 in short) [1] is the instantiation of the Segment Routing (SR) [2] architecture on the IPv6 dataplane. In SRv6, the segment identifiers (SID) are IPv6 addresses and the segment list (SID List) is carried in the Segment Routing Header (SRH). A segment may be bound to a specific packet processing operation called "behavior". The RFC8986 [3] defines and standardizes the most common/relevant behaviors for network operators, e.g., End, End.X and End.T and so on. The RFC8986 also introduces the "flavors" framework aiming to modify or extend the capabilities of SRv6 End, End.X and End.T behaviors. Specifically, these behaviors support the following flavors (either individually or in combinations): - Penultimate Segment Pop (PSP); - Ultimate Segment Pop (USP); - Ultimate Segment Decapsulation (USD). Such flavors enable an End/End.X/End.T behavior to pop the SRH on the penultimate/ultimate SR endpoint node listed in the SID List or to perform a full decapsulation. Currently, the Linux kernel supports a large subset of behaviors described in RFC8986, including the End, End.X and End.T. However, PSP, USP and USD flavors have not yet been implemented. In this patchset, we extend the SRv6 subsystem to implement the PSP flavor in the SRv6 End behavior. To accomplish this task, we leverage the flavor framework previously introduced by another patchset required for supporting the efficient representation of the SID List through the NEXT-C-SID mechanism [4]. In details, the patchset is made of: - patch 1/3: seg6: factor out End lookup nexthop processing to a dedicated function - patch 2/3: seg6: add PSP flavor support for SRv6 End behavior - patch 3/3: selftests: seg6: add selftest for PSP flavor in SRv6 End behavior From the user space perspective, we do not need to change the iproute2 code to support the PSP flavor. However, we provide the man page for the PSP flavor in a separate patch. Comments, improvements and suggestions are always appreciated. Thank you all, Andrea [1] - RFC8754: https://datatracker.ietf.org/doc/html/rfc8754 [2] - RFC8402: https://datatracker.ietf.org/doc/html/rfc8402 [3] - RFC8986: https://datatracker.ietf.org/doc/html/rfc8986 [4] - https://datatracker.ietf.org/doc/html/draft-ietf-spring-srv6-srh-compression Andrea Mayer (3): seg6: factor out End lookup nexthop processing to a dedicated function seg6: add PSP flavor support for SRv6 End behavior selftests: seg6: add selftest for PSP flavor in SRv6 End behavior net/ipv6/seg6_local.c | 352 ++++++- tools/testing/selftests/net/Makefile | 1 + .../selftests/net/srv6_end_flavors_test.sh | 869 ++++++++++++++++++ 3 files changed, 1213 insertions(+), 9 deletions(-) create mode 100755 tools/testing/selftests/net/srv6_end_flavors_test.sh -- 2.20.1

[PATCH AUTOSEL 6.1 22/24] selftests: ocelot: tc_flower_chains: make test_vlan_ingress_modify() more comprehensive

by Sasha Levin

From: Vladimir Oltean <vladimir.oltean(a)nxp.com> [ Upstream commit bbb253b206b9c417928a6c827d038e457f3012e9 ] We have two IS1 filters of the OCELOT_VCAP_KEY_ANY key type (the one with "action vlan pop" and the one with "action vlan modify") and one of the OCELOT_VCAP_KEY_IPV4 key type (the one with "action skbedit priority"). But we have no IS1 filter with the OCELOT_VCAP_KEY_ETYPE key type, and there was an uncaught breakage there. To increase test coverage, convert one of the OCELOT_VCAP_KEY_ANY filters to OCELOT_VCAP_KEY_ETYPE, by making the filter also match on the MAC SA of the traffic sent by mausezahn, $h1_mac.

I changed it to 0x200a93. The test passed on my machine. But I don't have a FRED system to test the special case. Didn't manage to apply the feedback from Andrew about the way to handle redzone properly, though. Something like this... ---------- This is just an RFC patchset. Xin Li reported sysret_rip test fails at: assert(ctx->uc_mcontext.gregs[REG_EFL] == ctx->uc_mcontext.gregs[REG_R11]); in a FRED system. Handle the FRED system scenario too. There are two patches in this series. Comments welcome... Note: Only tested for 'syscall' sets %rcx=%rip and %r11=%rflags case. I don't have a FRED system to test it.

[PATCH] mm: userfaultfd: add UFFDIO_CONTINUE_MODE_WP to install WP PTEs

by Axel Rasmussen

UFFDIO_COPY already has UFFDIO_COPY_MODE_WP, so when installing a new PTE to resolve a missing fault, one can install a write-protected one. This is useful when using UFFDIO_REGISTER_MODE_{MISSING,WP} in combination. So, add an analogous UFFDIO_CONTINUE_MODE_WP, which does the same thing but for *minor* faults. Rename "wp_copy" arguments to "wp_mode", since the mode now applies more widely than just to the copy operation. Update the selftest to do some very basic exercising of the new flag.
