Subject: [PATCH v3 0/2] bpf: permit JIT allocations to be served outside the module region
On arm64, modules are allocated from a 128 MB window which is close to
the core kernel, so that relative direct branches are guaranteed to be
in range (except in some KASLR configurations). Also, module_alloc()
is in charge of allocating KASAN shadow memory when running with KASAN
enabled.
This means that the way BPF reuses module_alloc()/module_memfree() is
undesirable on arm64 (and potentially other architectures as well),
and so this series refactors BPF's use of those functions to permit
architectures to change this behavior.
Patch #1 breaks out the module_alloc() and module_memfree() calls into
__weak functions so they can be overridden.
Patch #2 implements the new alloc/free overrides for arm64
Changes since v2:
- properly build time and runtime tested this time (log after the diffstat)
- create a dedicated 128 MB region at the top of the vmalloc space for BPF
programs, ensuring that the programs will be in branching range of each
other (which we currently rely upon) but at an arbitrary distance from
the kernel and modules (which we don't care about)
Changes since v1:
- Drop misguided attempt to 'fix' and refactor the free path. Instead,
just add another __weak wrapper for the invocation of module_memfree()
