      arm64: bpf: jit JMP_JSET_{X,K} · 98397fc5
      Zi Shen Lim authored
      Original implementation commit e54bcde3 ("arm64: eBPF JIT compiler")
      had the relevant code paths, but due to an oversight always fail jiting.
      
      As a result, we had been falling back to BPF interpreter whenever a BPF
      program has JMP_JSET_{X,K} instructions.
      
      With this fix, we confirm that the corresponding tests in lib/test_bpf
      continue to pass, and also jited.

      net/route: enforce hoplimit max value · 626abd59
      Paolo Abeni authored
      Currently, when creating or updating a route, no check is performed
      in both ipv4 and ipv6 code to the hoplimit value.
      
      The caller can i.e. set hoplimit to 256, and when such route will
       be used, packets will be sent with hoplimit/ttl equal to 0.
      
      This commit adds checks for the RTAX_HOPLIMIT value, in both ipv4
      ipv6 route code, substituting any value greater than 255 with 255.
      
      This is consistent with what is currently done for ADVMSS and MTU
      in the ipv4 code.

      nf_conntrack: avoid kernel pointer value leak in slab name · 31b0b385
      Linus Torvalds authored
      The slab name ends up being visible in the directory structure under
      /sys, and even if you don't have access rights to the file you can see
      the filenames.
      
      Just use a 64-bit counter instead of the pointer to the 'net' structure
      to generate a unique name.
      
      This code will go away in 4.7 when the conntrack code moves to a single
      kmemcache, but this is the backportable simple solution to avoiding
      leaking kernel pointers to user space.
      
      Fixes: 5b3501fa ("netfilter: nf_conntrack: per netns nf_conntrack_cachep")
