It acts as cleanup even despite init_net_initialized
assignment is reordered with the linking of net now.
This variable is need for proc_net_init() called from:

Reset packet doesn't use user configured flowlabel, instead, it always
uses 0. This will cause inconsistency for flowlabel. tw sock already
records flowlabel info, so we can directly use it.

Hi,
Please see below tcpdump output:

We are using sk_txhash to calculate flowlabel, but sk_txhash isn't
always available, for example, in inet_timewait_sock. This causes
problem for reset packet, which will have a different flowlabel. This
causes our router doesn't correctly close tcp connection. We are using
flowla

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 bpf_override_funciton
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.

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 injection purpo
From: Josef Bacik
This allows us to do error injection with BPF for open_ctree.

I've reworked this to be opt-in only as per Igno and Alexei. Still needs to go
through Dave because of the bpf bits, but I need tracing guys to weigh in and
sign off on my approach please.
v5->v6:
- add BPF_ALLOW_ERROR_INJECTION() tagging for functions that will support this
feature. This way

Otherwise tun_dst argument is unused there. Currently, ip6_tnl_rcv()
