      libbf: Fix uninitialized pointer at btf__parse_raw() · 932ac54a
      Daniel T. Lee authored
      Recently, from commit 94a1fedd ("libbpf: Add btf__parse_raw() and
      generic btf__parse() APIs"), new API has been added to libbpf that
      allows to parse BTF from raw data file (btf__parse_raw()).
      
      The commit derives build failure of samples/bpf due to improper access
      of uninitialized pointer at btf_parse_raw().
      
          btf.c: In function btf__parse_raw:
          btf.c:625:28: error: btf may be used uninitialized in this function
            625 |  return err ? ERR_PTR(err) : btf;
                |         ~~~~~~~~~~~~~~~~~~~^~~~~
      
      This commit fixes the build failure of samples/bpf by adding code of
      initializing btf pointer as NULL.
      
      Fixes: 94a1fedd ("libbpf: Add btf__parse_raw() and generic btf__parse() APIs")

      ====================
      Andrii raised a concern that current uapi for bpf iterator map
      element is a little restrictive and not suitable for future potential
      complex customization. This is a valid suggestion, considering people
      may indeed add more complex custimization to the iterator, e.g.,
      cgroup_id + user_id, etc. for task or task_file. Another example might
      be map_id plus additional control so that the bpf iterator may bail
      out a bucket earlier if a bucket has too many elements which may hold
      lock too long and impact other parts of systems.
      
      Patch #1 modified uapi with kernel changes. Patch #2
      adjusted libbpf api accordingly.
      
      Changelogs:
        v3 -> v4:
          . add a forward declaration of bpf_iter_link_info in
            tools/lib/bpf/bpf.h in case that libbpf is built against
            not-latest uapi bpf.h.
          . target the patch set to "bpf" instead of "bpf-next"
        v2 -> v3:
          . undo "not reject iter_info.map.map_fd == 0" from v1.
            In the future map_fd may become optional, so let us use map_fd == 0
            indicating the map_fd is not set by user space.
          . add link_info_len to bpf_iter_attach_opts to ensure always correct
            link_info_len from user. Otherwise, libbpf may deduce incorrect
            link_info_len if it uses different uapi header than the user app.
        v1 -> v2:
          . ensure link_create target_fd/flags == 0 since they are not used. (Andrii)
          . if either of iter_info ptr == 0 or iter_info_len == 0, but not both,
            return error to user space. (Andrii)
          . do not reject iter_info.map.map_fd == 0, go ahead to use it trying to
            get a map reference since the map_fd is required for map_elem iterator.
          . use bpf_iter_link_info in bpf_iter_attach_opts instead of map_fd.
            this way, user space is responsible to set up bpf_iter_link_info and
            libbpf just passes the data to the kernel, simplifying libbpf design.
            (Andrii)

      tools/bpf: Support new uapi for map element bpf iterator · 74fc097d
      Yonghong Song authored
      Previous commit adjusted kernel uapi for map
      element bpf iterator. This patch adjusted libbpf API
      due to uapi change. bpftool and bpf_iter selftests
      are also changed accordingly.

      bpf: Change uapi for bpf iterator map elements · 5e7b3020
      Yonghong Song authored
      Commit a5cbe05a ("bpf: Implement bpf iterator for
      map elements") added bpf iterator support for
      map elements. The map element bpf iterator requires
      info to identify a particular map. In the above
      commit, the attr->link_create.target_fd is used
      to carry map_fd and an enum bpf_iter_link_info
      is added to uapi to specify the target_fd actually
      representing a map_fd:
          enum bpf_iter_link_info {
      	BPF_ITER_LINK_UNSPEC = 0,
      	BPF_ITER_LINK_MAP_FD = 1,
      
      	MAX_BPF_ITER_LINK_INFO,
          };
      
      This is an extensible approach as we can grow
      enumerator for pid, cgroup_id, etc. and we can
      unionize target_fd for pid, cgroup_id, etc.
      But in the future, there are chances that
      more complex customization may happen, e.g.,
      for tasks, it could be filtered based on
      both cgroup_id and user_id.
      
      This patch changed the uapi to have fields
      	__aligned_u64	iter_info;
      	__u32		iter_info_len;
      for additional iter_info for link_create.
      The iter_info is defined as
      	union bpf_iter_link_info {
      		struct {
      			__u32   map_fd;
      		} map;
      	};
      
      So future extension for additional customization
      will be easier. The bpf_iter_link_info will be
      passed to target callback to validate and generic
      bpf_iter framework does not need to deal it any
      more.
      
      Note that map_fd = 0 will be considered invalid
      and -EBADF will be returned to user space.

      selftests/bpf: Prevent runqslower from racing on building bpftool · 6bcaf41f
      Andrii Nakryiko authored
      runqslower's Makefile is building/installing bpftool into
      $(OUTPUT)/sbin/bpftool, which coincides with $(DEFAULT_BPFTOOL). In practice
      this means that often when building selftests from scratch (after `make
      clean`), selftests are racing with runqslower to simultaneously build bpftool
      and one of the two processes fail due to file being busy. Prevent this race by
      explicitly order-depending on $(BPFTOOL_DEFAULT).

      Pull drm updates from Dave Airlie:
       "New xilinx displayport driver, AMD support for two new GPUs (more
        header files), i915 initial support for RocketLake and some work on
        their DG1 (discrete chip).
      
        The core also grew some lockdep annotations to try and constrain what
        drivers do with dma-fences, and added some documentation on why the
        idea of indefinite fences doesn't work.
      
        The long list is below.

      ====================
      misc bug fixes for the hso driver
      
      1. Code reuse led to an unregistration of a net driver that has not been
      registered
      2. The kernel complains generically if kmalloc with GFP_KERNEL fails
      3. A race that can lead to an URB that is in use being reused or
      a use after free

      an error code has already been set or cleared yet
      the URB has not been given back. We cannot do
      such an optimization and must unlink unconditionally.

      hso: fix bailout in error case of probe · 5fcfb6d0
      Oliver Neukum authored
      The driver tries to reuse code for disconnect in case
      of a failed probe.
      If resources need to be freed after an error in probe, the
      netdev must not be freed because it has never been registered.
      Fix it by telling the helper which path we are in.

      Before switch from discontigmem to sparsemem, there always was
      CONFIG_NEED_MULTIPLE_NODES=y because it was selected by DISCONTIGMEM.
      Without DISCONTIGMEM it is possible to have SPARSEMEM without NUMA for
      SGI_IP27 and as many things there rely on custom node definition, the
      build breaks.
      
      As Thomas noted "... there are right now too many places in IP27 code,
      which assumes NUMA enabled", the simplest solution would be to always
      enable NUMA for SGI-IP27 builds.

         - Report the size of the page table mapping out of hmm_range_fault().
      
           This makes it easier to establish a large/huge/etc mapping in the
           device's page table.
      
         - Allow devices to ignore the invalidations during migration in cases
           where the migration is not going to change pages.
      
           For instance migrating pages to a device does not require the
           device to invalidate pages already in the device.
      
         - Update nouveau and hmm_tests to use the above"

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.9 kernel cycle.
      
        There is nothing too exciting in it, but a new macro that fixes a
        build failure on a minor ARM32 platform that appeared yesterday is
        part of it so we better merge it.
      
        Core changes:
      
         - Introduce the for_each_requested_gpio() macro to help in dependent
           code all over the place. Also patch a few locations to use it while
           we are at it.
      
         - Split out the sysfs code into its own file.
      
         - Split out the character device code into its own file, then make a
           set of refactorings and improvements to this code. We are setting
           the stage to revamp the userspace API a bit in the next cycle.
      
         - Fix a whole slew of kerneldoc that was wrong or missing.
      
        New drivers:
      
         - The PCA953x driver now supports the PCAL9535.
      
        Driver improvements:
      
         - A host of incremental modernizations and improvements to the
           PCA953x driver.
      
         - Incremental improvements to the Xilinx Zynq driver.
      
         - Some improvements to the GPIO aggregator driver.
      
         - I ran all over the place switching all threaded and other drivers
           requesting their own IRQ while using the core GPIO IRQ helpers to
           pass the GPIO irq chip as a template instead of calling the
           explicit set-up functions. Next merge window we may retire the old

      selftests/net: relax cpu affinity requirement in msg_zerocopy test · 16f6458f
      Willem de Bruijn authored
      The msg_zerocopy test pins the sender and receiver threads to separate
      cores to reduce variance between runs.
      
      But it hardcodes the cores and skips core 0, so it fails on machines
      with the selected cores offline, or simply fewer cores.
      
      The test mainly gives code coverage in automated runs. The throughput
      of zerocopy ('-z') and non-zerocopy runs is logged for manual
      inspection.
      
      Continue even when sched_setaffinity fails. Just log to warn anyone
      interpreting the data.

      ====================
      selftests: rtnetlink: Fix for false-negative return values
      
      This patchset will address the false-negative return value issue
      caused by the following:
        1. The return value "ret" in this script will be reset to 0 from
           the beginning of each sub-test in rtnetlink.sh, therefore this
           rtnetlink test will always pass if the last sub-test has passed.
        2. The test result from two sub-tests in kci_test_encap() were not
           being processed, thus they will not affect the final test result
           of this test.

      Po-Hsu Lin authored
      kci_test_encap() is actually composed by two different sub-tests,
      kci_test_encap_vxlan() and kci_test_encap_fou()
      
      Therefore we should check the test result of these two in
      kci_test_encap() to let the script be aware of the pass / fail status.
      Otherwise it will generate false-negative result like below:

      net: dsa: sja1105: use detected device id instead of DT one on mismatch · 0b0e2997
      Vladimir Oltean authored
      Although we can detect the chip revision 100% at runtime, it is useful
      to specify it in the device tree compatible string too, because
      otherwise there would be no way to assess the correctness of device tree
      bindings statically, without booting a board (only some switch versions
      have internal RGMII delays and/or an SGMII port).
      
      But for testing the P/Q/R/S support, what I have is a reworked board
      with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
      want to keep a separate device tree blob just for this one-off board.
      Since just the chip has been replaced, its RGMII delay setup is
      inherently the same (meaning: delays added by the PHY on the slave
      ports, and by PCB traces on the fixed-link CPU port).
      
      For this board, I'd rather have the driver shout at me, but go ahead and
      use what it found even if it doesn't match what it's been told is there.

      tipc: set ub->ifindex for local ipv6 address · 5a6f6f57
      Xin Long authored
      Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
      ipv6_sock_mc_join() may make the wrong dev join the multicast
      address in enable_mcast(). This causes that tipc links would
      never be created.
      
      So fix it by getting the right netdev and setting ub->ifindex,
      as it does for ipv4 address.

      ovs_flow_tbl_destroy always is called from RCU callback
