From 506ada89629ec7059b96ecfb0dc7d33ece0103ca Mon Sep 17 00:00:00 2001 From: Eduard Zingerman Date: Fri, 4 Sep 2026 17:05:56 -0700 Subject: bpf: mark a NULL kfunc argument precise check_kfunc_arg() allows bpf_register_is_null() for nullable arguments w/o marking the underlying scalar register precise. Hence a checkpoint created on such a path would prune against arbitrary scalar value. Fixes: 3bda08b63670 ("bpf: Allow NULL buffers in bpf_dynptr_slice(_rw)") Signed-off-by: Eduard Zingerman Link: https://lore.kernel.org/r/20260904-register-is-null-precise-fixes-v1-5-0f5a360ff15d@gmail.com Signed-off-by: Alexei Starovoitov --- Documentation/crypto/libcrypto-auth-encryption.rst | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 Documentation/crypto/libcrypto-auth-encryption.rst (limited to 'Documentation/crypto/libcrypto-auth-encryption.rst') diff --git a/Documentation/crypto/libcrypto-auth-encryption.rst b/Documentation/crypto/libcrypto-auth-encryption.rst new file mode 100644 index 000000000..1e527685a --- /dev/null +++ b/Documentation/crypto/libcrypto-auth-encryption.rst @@ -0,0 +1,20 @@ +..
