From c756ba4e975097bf74b952367e2cd1a8db466c69 Mon Sep 17 00:00:00 2001 From: Dmitry Vyukov Date: Mon, 2 Dec 2024 10:57:36 +0100 Subject: tools/syz-declextract: extract file_operations descriptions Extend the clang tool to locate file_operations variables and arrays and dump open/read/write/mmap/ioctl callbacks for each. It also tries to extract set of ioctl commands and argument types for them in a simple best-effort way (for now). It just locates switch in the ioctl callback and extracts each case as a command. --- .../testdata/include/uapi/file_operations.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 tools/syz-declextract/testdata/include/uapi/file_operations.h (limited to 'tools/syz-declextract/testdata/include/uapi/file_operations.h') diff --git a/tools/syz-declextract/testdata/include/uapi/file_operations.h b/tools/syz-declextract/testdata/include/uapi/file_operations.h new file mode 100644 index 000000000..6a2a8d259 --- /dev/null +++ b/tools/syz-declextract/testdata/include/uapi/file_operations.h @@ -0,0 +1,14 @@ +// Copyright 2024 syzkaller project authors.
