classes/package.bbclass: Add fixup_perms
Add a new function that is responsible for fixing directory and file permissions, owners and groups during the packaging process. This will fix various issues where two packages may create the same directory and end up with different permissions, owner and/or group. The issue being resolved is that if two packages conflict in their ownership of a directory, the first installed into the rootfs sets the permissions. This leads to a least potentially non-deterministic filesystems, at worst security defects. The user can specify their own settings via the configuration files specified in FILESYSTEM_PERMS_TABLES. If this is not defined, it will fall back to loading files/fs-perms.txt from BBPATH. The format of this file is documented within the file. By default all of the system directories, specified in bitbake.conf, will be fixed to be 0755, root, root. The fs-perms.txt contains a few default entries to correct documentation, locale, headers and debug sources. It was discovered these are often incorrect due to being directly copied from the build user environment. The entries needed to match the base-files package have also been added. Also tweak a couple of warnings to provide more diagnostic information. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
