          "text": "In the Linux kernel, the following vulnerability has been resolved:\n\nipvs: fix UB due to uninitialized stack access in ip_vs_protocol_init()\n\nUnder certain kernel configurations when building with Clang/LLVM, the\ncompiler does not generate a return or jump as the terminator\ninstruction for ip_vs_protocol_init(), triggering the following objtool\nwarning during build time:\n\n  vmlinux.o: warning: objtool: ip_vs_protocol_init() falls through to next function __initstub__kmod_ip_vs_rr__935_123_ip_vs_rr_init6()\n\nAt runtime, this either causes an oops when trying to load the ipvs\nmodule or a boot-time panic if ipvs is built-in. This same issue has\nbeen reported by the Intel kernel test robot previously.\n\nDigging deeper into both LLVM and the kernel code reveals this to be a\nundefined behavior problem. ip_vs_protocol_init() uses a on-stack buffer\nof 64 chars to store the registered protocol names and leaves it\nuninitialized after definition. The function calls strnlen() when\nconcatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCE\nstrnlen() performs an extra step to check whether the last byte of the\ninput char buffer is a null character (commit 3009f891bb9f (\"fortify:\nAllow strlen() and strnlen() to pass compile-time known lengths\")).\nThis, together with possibly other configurations, cause the following\nIR to be generated:\n\n  define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #5 section \".init.text\" align 16 !kcfi_type !29 {\n    %1 = alloca [64 x i8], align 16\n    ...\n\n  14:                                               ; preds = %11\n    %15 = getelementptr inbounds i8, ptr %1, i64 63\n    %16 = load i8, ptr %15, align 1\n    %17 = tail call i1 @llvm.is.constant.i8(i8 %16)\n    %18 = icmp eq i8 %16, 0\n    %19 = select i1 %17, i1 %18, i1 false\n    br i1 %19, label %20, label %23\n\n  20:                                               ; preds = %14\n    %21 = call i64 @strlen(ptr noundef nonnull dereferenceable(1) %1) #23\n    ...\n\n  23:                                               ; preds = %14, %11, %20\n    %24 = call i64 @strnlen(ptr noundef nonnull dereferenceable(1) %1, i64 noundef 64) #24\n    ...\n  }\n\nThe above code calculates the address of the last char in the buffer\n(value %15) and then loads from it (value %16). Because the buffer is\nnever initialized, the LLVM GVN pass marks value %16 as undefined:\n\n  %13 = getelementptr inbounds i8, ptr %1, i64 63\n  br i1 undef, label %14, label %17\n\nThis gives later passes (SCCP, in particular) more DCE opportunities by\npropagating the undef value further, and eventually removes everything\nafter the load on the uninitialized stack location:\n\n  define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #0 section \".init.text\" align 16 !kcfi_type !11 {\n    %1 = alloca [64 x i8], align 16\n    ...\n\n  12:                                               ; preds = %11\n    %13 = getelementptr inbounds i8, ptr %1, i64 63\n    unreachable\n  }\n\nIn this way, the generated native code will just fall through to the\nnext function, as LLVM does not generate any code for the unreachable IR\ninstruction and leaves the function without a terminator.\n\nZero the on-stack buffer to avoid this possible UB.",
