To get a full tag (and not just a VID) we should access the TCI
except the VLAN_TAG_PRESENT field (which means that 802.1q header
is present). Also ensure that the VLAN_TAG_PRESENT stay on its place

We have to return the boolean here if the tag presents
or not, not just ANDing the TCI with the mask which results to:

Hi Denis,
Is this the same version of test_bpf that is in Linus' tree?
I don't see any fails with that version, am I missing something?
[ 187.690640] test_bpf: #18 LD_VLAN_TAG_PRESENT 46 50 PASS
cheers

Did you try to modprobe test_bpf after enabling JIT, i.e. :
echo 1 > /proc/sys/net/core/bpf_jit_enable
Last time I tested with ppc64, I saw the interpreter passing
while JIT failed, which the fix above should address.
Cheers,
Daniel

Right, I thought CONFIG_BPF_JIT=y was sufficient.
But that just makes it available, I need to *also* enable it at runtime.

Yes, it's an extra runtime knob which still needs to be enabled by
the admin for security reasons. This knob also allows you to enable
the debugging interface `echo 2 >/proc/sys/net/core/bpf_jit_enable`
where the disassembly can be read out via: tools/net/bpf_jit_disasm.c
