Merge branch 'bpf-x86-fix-bpf_throw-in-a-prog-with-a-private-stack'
Alexei Starovoitov says:
====================
bpf, x86: Fix bpf_throw() in a prog with a private stack
From: Alexei Starovoitov <ast@kernel.org>
On x86-64 a prog whose main prog has a private stack and that calls
bpf_throw() returns to the kernel with wrong callee saved registers. The
kernel crashes. A tracepoint prog or an fentry prog with more than 48 bytes
of stack is sufficient.
Patch 1 is the fix. Patch 2 has the tests. The existing tests of this
combination are loaded, but they never run.
