bpf: Add the missing BPF_LINK_TYPE invocation for sockmap

2024-11-01T01:02:38+00:00

[ Upstream commit c2f803052bc7a7feb2e03befccc8e49b6ff1f5f5 ]

There is an out-of-bounds read in bpf_link_show_fdinfo() for the sockmap
link fd. Fix it by adding the missing BPF_LINK_TYPE invocation for
sockmap link

Also add comments for bpf_link_type to prevent missing updates in the
future.

tools/include: Sync filesystem headers with the kernel sources

2024-08-07T17:59:07+00:00

To pick up changes from:

  0f9ca80fa4f9 fs: Add initial atomic write support info to statx
  f9af549d1fd3 fs: export mount options via statmount()
  0a3deb11858a fs: Allow listmount() in foreign mount namespace
  09b31295f833 fs: export the mount ns id via statmount
  d04bccd8c19d listmount: allow listing in reverse order
  bfc69fd05ef9 fs/procfs: add build ID fetching to PROCMAP_QUERY API
  ed5d583a88a9 fs/procfs: implement efficient VMA querying API for /proc//maps

This should be used to beautify FS syscall arguments and it addresses
these tools/perf build warnings:

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf and netfilter.

  A lot of networking people were at a conference last week, busy
  catching COVID, so relatively short PR.

  Current release - regressions:

   - tcp: process the 3rd ACK with sk_socket for TFO and MPTCP

  Current release - new code bugs:

   - l2tp: protect session IDR and tunnel session list with one lock,
     make sure the state is coherent to avoid a warning

   - eth: bnxt_en: update xdp_rxq_info in queue restart logic

   - eth: airoha: fix location of the MBI_RX_AGE_SEL_MASK field

  Previous releases - regressions:

   - xsk: require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len,
     the field reuses previously un-validated pad

  Previous releases - always broken:

   - tap/tun: drop short frames to prevent crashes later in the stack

   - eth: ice: add a per-VF limit on number of FDIR filters

   - af_unix: disable MSG_OOB handling for sockets in sockmap/sockhash"
