From 1ee60356c2dca938362528404af95b8ef3e49b6a Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Sat, 4 Nov 2023 13:43:37 -0700 Subject: gcc-plugins: randstruct: Only warn about true flexible arrays The randstruct GCC plugin tried to discover "fake" flexible arrays to issue warnings about them in randomized structs. In the future LSM overhead reduction series, it would be legal to have a randomized struct with a 1-element array, and this should _not_ be treated as a flexible array, especially since commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3"). Disable the 0-sized and 1-element array discovery logic in the plugin, but keep the "true" flexible array check.

Prado" Date: Tue, 7 Nov 2023 17:55:28 -0500 Subject: dt: dt-extract-compatibles: Don't follow symlinks when walking tree MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The iglob function, which we use to find C source files in the kernel tree, always follows symbolic links. This can cause unintentional recursions whenever a symbolic link points to a parent directory. A common scenario is building the kernel with the output set to a directory inside the kernel tree, which will contain such a symlink. Instead of using the iglob function, use os.walk to traverse the directory tree, which by default doesn't follow symbolic links. fnmatch is then used to match the glob on the filename, as well as ignore hidden files (which were ignored by default with iglob). This approach runs just as fast as using iglob.
