The requirements are: - - Paths must be directories or symlinks to directories. - - Each directory is read and sorted into alphabetical order - before processing. - - A directory is type 1 iff it was specified on a path statement - (either explicit or default) and the directory contains a - subdirectory with one of the known names and the directory name - does not end with "/kernel". Otherwise it is type 2. - - In a type 1 directory, walk the kernel subdirectory if it exists, - then the old known names in their historical order then any - remaining directory entries in alphabetical order and finally any - non-directory entries in alphabetical order. - - Entries in a type 1 directory are filtered against the "prune" - list. A type 1 directory can contain additional files which - are not modules nor symlinks to modules. The prune list skips - known additional files, if a distribution wants to store - additional text files in the top level directory they should be - added to the prune list. - - A type 2 directory must contain only modules or symlinks to - modules. They are processed in alphabetical order, without - pruning. Symlinks to directories are an error in type 2 - directories. - - The user function is not called for type 1 directories, nor for - pruned entries. It is called for type 2 directories and their - contents. It is also called for any files left in a type 1 - directory after pruning and processing type 2 subdirectories. - The user function never sees symlinks, they are resolved before - calling the function. - - Why have different directory types? The original file tree - walk was not well defined. Some users specified each directory - individually, others just pointed at the top level directory. - Either version worked until the "build" symlink was added. Now - users who specify the top level directory end up running the - entire kernel source tree looking for modules, not nice. We - cannot just ignore symlinks because pcmcia uses symlinks to - modules for backwards compatibility. - - Type 1 is when a user specifies the top level directory which needs - special processing, type 2 is individual subdirectories. But the - only way to tell the difference is by looking at the contents. The - "/kernel" directory introduced in 2.3.12 either contains nothing - (old make modules_install) or contains all the kernel modules using - the same tree structure as the source. Because "/kernel" can - contain old names but is really a type 2 directory, it is detected - as a special case. - */ - -#include <dirent.h> -#include <errno.h> -#include <limits.h> -#include <malloc.h> -#include <stdlib.h> -#include <string.h> -#include <sys/stat.h> - -#include "util.h" -#include "config.h" - -extern char *tbpath[];
