      The build of sparc allmodconfig fails with the error:

      	undefined!
      
      of_irq_to_resource() is defined when CONFIG_OF_IRQ is defined. And also
      CONFIG_OF_IRQ can only be defined if CONFIG_IRQ is defined. So we can
      safely use #if defined(CONFIG_OF_IRQ) in the code.

      Mantas M 提交于
      The protocol field is checked when deleting IPv4 routes, but ignored for
      IPv6, which causes problems with routing daemons accidentally deleting
      externally set routes (observed by multiple bird6 users).
      
      This can be verified using `ip -6 route del <prefix> proto something`.

      ====================
      Couple of BPF fixes
      
      This set contains three BPF fixes for net, one that addresses the
      complaint from Geert wrt static allocations, and the other is a fix
      wrt mem accounting that I found recently during testing and there's
      still one more fix on the map value marking.
      
      Thanks!
      
      v1 -> v2:
        - Patch 1 as is.
        - Fixed kbuild bot issue by letting charging helpers stay in the
          syscall.c, since there locked_vm is valid and only export the
          ones needed by bpf_prog_realloc(). Add empty stubs in case the
          bpf syscall is not enabled.
        - Added patch 3 that addresses one more issue in map val marking.

      This issue got uncovered after the fix in a08dd0da ("bpf: fix
      regression on verifier pruning wrt map lookups"). The reason why it
      wasn't noticed before was, because as mentioned in a08dd0da,
      mark_map_regs() was doing the id matching incorrectly based on the
      uncached regs[regno].id. So, in the first loop, we walked all regs
      and as soon as we found regno == i, then this reg's id was cleared
      when calling mark_reg_unknown_value() thus that every subsequent
      register was probed against id of 0 (which, in combination with the
      PTR_TO_MAP_VALUE_OR_NULL type is an invalid condition that no other
      register state can hold), and therefore wasn't type transitioned such
      as in the spilled register case for the second loop.
      
      Now since that got fixed, it turned out that 57a09bf0 ("bpf:
      Detect identical PTR_TO_MAP_VALUE_OR_NULL registers") used
      mark_reg_unknown_value() incorrectly for the spilled regs, and thus
      hitting the BUG_ON() in some cases due to regno >= MAX_BPF_REG.
      
      Although spilled regs have the same type as the non-spilled regs
      for the verifier state, that is, struct bpf_reg_state, they are
      semantically different from the non-spilled regs. In other words,
      there can be up to 64 (MAX_BPF_STACK / BPF_REG_SIZE) spilled regs
      in the stack, for example, register R<x> could have been spilled by
      the program to stack location X, Y, Z, and in mark_map_regs() we
      need to scan these stack slots of type STACK_SPILL for potential
      registers that we have to transition from PTR_TO_MAP_VALUE_OR_NULL.
      Therefore, depending on the location, the spilled_regs regno can
      be a lot higher than just MAX_BPF_REG's value since we operate on
      stack instead. The reset in mark_reg_unknown_value() itself is
      just fine, only that the BUG_ON() was inappropriate for this. Fix
      it by making a __mark_reg_unknown_value() version that can be
      called from mark_map_reg() generically; we know for the non-spilled
      case that the regno is always < MAX_BPF_REG anyway.

      bpf: fix overflow in prog accounting · 5ccb071e
      Daniel Borkmann 提交于
      Commit aaac3ba9 ("bpf: charge user for creation of BPF maps and
      programs") made a wrong assumption of charging against prog->pages.
      Unlike map->pages, prog->pages are still subject to change when we
      need to expand the program through bpf_prog_realloc().
      
      This can for example happen during verification stage when we need to
      expand and rewrite parts of the program. Should the required space
      cross a page boundary, then prog->pages is not the same anymore as
      its original value that we used to bpf_prog_charge_memlock() on. Thus,
      we'll hit a wrap-around during bpf_prog_uncharge_memlock() when prog
      is freed eventually. I noticed this that despite having unlimited
      memlock, programs suddenly refused to load with EPERM error due to
      insufficient memlock.
      
      There are two ways to fix this issue. One would be to add a cached
      variable to struct bpf_prog that takes a snapshot of prog->pages at the
      time of charging. The other approach is to also account for resizes. I
      chose to go with the latter for a couple of reasons: i) We want accounting
      rather to be more accurate instead of further fooling limits, ii) adding
      yet another page counter on struct bpf_prog would also be a waste just
      for this purpose. We also do want to charge as early as possible to
      avoid going into the verifier just to find out later on that we crossed
      limits. The only place that needs to be fixed is bpf_prog_realloc(),
      since only here we expand the program, so we try to account for the
      needed delta and should we fail, call-sites check for outcome anyway.
      On cBPF to eBPF migrations, we don't grab a reference to the user as
      they are charged differently. With that in place, my test case worked
      fine.

      bpf: dynamically allocate digest scratch buffer · aafe6ae9
      Daniel Borkmann 提交于
      Geert rightfully complained that 7bd509e3 ("bpf: add prog_digest
      and expose it via fdinfo/netlink") added a too large allocation of
      variable 'raw' from bss section, and should instead be done dynamically:
      
        # ./scripts/bloat-o-meter kernel/bpf/core.o.1 kernel/bpf/core.o.2
        add/remove: 3/0 grow/shrink: 0/0 up/down: 33291/0 (33291)
        function                                     old     new   delta
        raw                                            -   32832  +32832
        [...]
      
      Since this is only relevant during program creation path, which can be
      considered slow-path anyway, lets allocate that dynamically and be not
      implicitly dependent on verifier mutex. Move bpf_prog_calc_digest() at
      the beginning of replace_map_fd_with_map_ptr() and also error handling
      stays straight forward.

      ====================
      GTP tunneling fixes for net
      
      The following patchset contains two GTP tunneling fixes for your net
      tree, they are:
      
      1) Offset to IPv4 header in gtp_check_src_ms_ipv4() is incorrect, thus
         this function always succeeds and therefore this defeats this sanity
         check. This allows packets that have no PDP to go though, patch from
         Lionel Gauthier.
      
      2) According to Note 0 of Figure 2 in Section 6 of 3GPP TS 29.060 v13.5.0
         Release 13, always set GTPv1 reserved bit to zero. This may cause
         interoperability problems, patch from Harald Welte.
      
      Please, apply, thanks a lot!

      gtp: Fix initialization of Flags octet in GTPv1 header · d928be81
      Harald Welte 提交于
      When generating a GTPv1 header in gtp1_push_header(), initialize the
      'reserved' bit to zero.  All 3GPP specifications for GTPv1 from Release
      99 through Release 13 agree that a transmitter shall set this bit to
      zero, see e.g. Note 0 of Figure 2 in Section 6 of 3GPP TS 29.060 v13.5.0
      Release 13, available from
      http://www.etsi.org/deliver/etsi_ts/129000_129099/129060/13.05.00_60/ts_129060v130500p.pdfSigned-off-by: NHarald Welte <laforge@gnumonks.org>

      gtp: gtp_check_src_ms_ipv4() always return success · 88edf103
      Lionel Gauthier 提交于
      gtp_check_src_ms_ipv4() did not find the PDP context matching with the
      UE IP address because the memory location is not right, but the result
      is inverted by the Boolean "not" operator.  So whatever is the PDP
      context, any call to this function is successful.
