Since commit b2eed9b58811 ("arm64/kernel: kaslr: reduce module
randomization range to 2 GB"), for arm64 whether KASLR is enabled
or not, the module is placed within 2GB of the kernel region, so
s32 in bpf_kfunc_desc is sufficient to represente the offset of
module function relative to __bpf_call_base. The only thing needed
is to override bpf_jit_supports_kfunc_call().
Signed-off-by: Hou Tao <redacted>Could you rebase patch 2 & 3 and resend as they don't apply to bpf-next right now. Meanwhile, applied this one, thanks a lot!
