[PATCH v9 3/5] bpf: add a bpf_override_function helper

From: Josef Bacik Error injection is sloppy and very ad-hoc. BPF could fill this niche perfectly with it's kprobe functionality. We could make sure errors are only triggered in specific call chains that we care about with very specific situations. Accomplish this with the

[PATCH net] ipv6: mcast: better catch silly mtu values

From: Eric Dumazet syzkaller reported crashes in IPv6 stack [1] Xin Long found that lo MTU was set to silly values. IPv6 stack reacts to changes to small MTU, by disabling itself under RTNL. But there is a window where threads not using RTNL can see a wrong device mtu.

[RFC][PATCH] new byteorder primitives - ..._{replace,get}_bits()

A lot of drivers are open-coding the "replace these bits in __be32 with the following value" kind of primitives. Let's add them to byteorder.h. Primitives: {be,le}{16,32,64}_replace_bits(old, v, bit, nbits) {be,le}{16,32,64}_get_bits(val, bit, nbits) Essentially, it gives

[PATCH v9 4/5] samples/bpf: add a test for bpf_override_return

From: Josef Bacik This adds a basic test for bpf_override_return to verify it works. We override the main function for mounting a btrfs fs so it'll return -ENOMEM and then make sure that trying to mount a btrfs fs will fail. Acked-by: Alexei Starovoitov

[PATCH v9 1/5] add infrastructure for tagging functions as error injectable

From: Josef Bacik Using BPF we can override kprob'ed functions and return arbitrary values. Obviously this can be a bit unsafe, so make this feature opt-in for functions. Simply tag a function with KPROBE_ERROR_INJECT_SYMBOL in order to give BPF access to that function for error
