hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYQOP CVE: CVE-2024-49861
--------------------------------
enum bpf_type_flag is used only in kernel. Let's fix this kabi breakage by adding KABI_BROKEN_INSERT_ENUM and KABI_BROKEN_INSERT_ENUM macro.
Fixes: 656830f06678 ("bpf: Add MEM_UNINIT as a bpf_type_flag") Fixes: 834a586818e5 ("bpf: Allow helpers to accept pointers with a fixed size") Fixes: ec15a06019fe ("bpf: Fix helper writes to read-only maps") Signed-off-by: Xiaomeng Zhang zhangxiaomeng13@huawei.com --- include/linux/bpf.h | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-)
