Once we have more clarification/guidance after their fix,Song will follow-up.

Wed, 11 Nov 2020 00:25:53 +0100

Merge branch 'Integrate kernel module BTF support'Andrii Nakryiko says:====================This patch set adds BTF generation for kernel modules using a compact splitBTF approach. Respective patches have all the details.Kernel module BTFs rely on pahole's split BTF support, which is added in [0]and will be available starting from v1.19. Support for it is detectedautomatically during kernel build time.This patch set implements in-kernel support for split BTF loading andvalidation. It also extends GET_OBJ_INFO API for BTFs to return BTF's modulename and a flag whether BTF itself is in-kernel or user-provided. vmlinux BTFis also exposed to user-space through the same BTF object iteration APIs.Follow up patch set will utilize the fact that vmlinux and module BTFs nowhave associated ID to provide ability to attach BPF fentry/fexit/etc programsto functions defined in kernel modules.bpftool is also extended to show module/vmlinux BTF's name.

Tue, 10 Nov 2020 02:19:31 +0100

bpf: Load and verify kernel module BTFsAdd kernel module listener that will load/validate and unload module BTF.Module BTFs gets ID generated for them, which makes it possible to iteratethem with existing BTF iteration API. They are given their respective module'snames, which will get reported through GET_OBJ_INFO API. They are also markedas in-kernel BTFs for tooling to distinguish them from user-provided BTFs.Also, similarly to vmlinux BTF, kernel module BTFs are exposed throughsysfs as /sys/kernel/btf/. This is convenient for user-spacetools to inspect module BTF contents and dump their types with existing tools:[vmuser@archvm bpf]$ ls -la /sys/kernel/btftotal 0drwxr-xr-x 2 root root 0 Nov 4 19:46 .drwxr-xr-x 13 root root 0 Nov 4 19:46 .....-r--r--r-- 1 root root 888 Nov 4 19:46 irqbypass-r--r--r-- 1 root root 100225 Nov 4 19:46 kvm-r--r--r-- 1 root root 35401 Nov 4 19:46 kvm_intel-r--r--r-- 1 root root 120 Nov 4 19:46 pcspkr-r--r--r-- 1 root root 399 Nov 4 19:46 serio_raw-r--r--r-- 1 root root 4094095 Nov 4 19:46 vmlinuxSigned-off-by: Andrii Nakryiko Signed-off-by: Alexei Starovoitov Reviewed-by: Greg Kroah-Hartman Link: https://lore.kernel.org/bpf/20201110011932.3201430-5-andrii@kernel.org List of files: /linux/Documentation/ABI/testing/sysfs-kernel-btf
