From dad9228494e3cc03dc477e8109f43119390b53c4 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Mon, 9 Dec 2019 15:52:38 +0100 Subject: Only check for OS specific bad filenames when unpacking When converting a SquashFS image to a tarball, it makes no sense to refuse conversion if the filename is considered evil by the OS. This patch adds an option to is_filename_sane to check if the OS has a problem with the given file name. sqfs2tar sets it to false and converts everything while rdsquashfs sets it to true when unpacking.
