[PATCH OLK-6.6] [Backport] bpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos

From: Eduard Zingerman <eddyz87(a)gmail.com> stable inclusion from stable-v6.6.54 commit 2288b54b96dcb55bedebcef3572bb8821fc5e708 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYQR6 CVE: CVE-2024-49850 [ Upstream commit 3d2786d65aaa954ebd3fcc033ada433e10da21c4 ] In case of malformed relocation record of kind BPF_CORE_TYPE_ID_LOCAL referencing a non-existing BTF type, function bpf_core_calc_relo_insn would cause a null pointer deference. Fix this by adding a proper check upper in call stack, as malformed relocation records could be passed from user space. Simplest reproducer is a program: r0 = 0 exit With a single relocation record: .insn_off = 0, /* patch first instruction */ .type_id = 100500, /* this type id does not exist */ .access_str_off = 6, /* offset of string "0" */ .kind = BPF_CORE_TYPE_ID_LOCAL, See the link for original reproducer or next commit for a test case.
