Add no-pad option to gensquashfs, sqfs2tar

2024-09-26T09:47:24+00:00

This works similar to the option for mksquashfs, preventing the image from being padded to device block size. Signed-off-by: David Oberhollenzer

Fix win32 filename sanitation for cases were we have clashes

2024-02-14T08:21:30+00:00

We fix filenames containing components like COM1 or PRN by appending an underscore ('_'). A squashfs archive may contain files that already have such a modifed name (e.g. COM1_) which would now potentially clash. This is fixed by matching any number of trailing '_' characters for the bad name and adding another one. So all existing names that start with an illegal prefix and have any number of underscores, will always have an additional one appended. Signed-off-by: David Oberhollenzer

Add utility function to fixup Windows file paths

2024-02-09T14:59:37+00:00

The idea is to iterate over a (canonicalized) path with forward slashes by components, i.e. file and directory names. Each name is then looked at by iterating over components, i.e. everything between dots. If a component is an illegal name, like COM1 or AUX, we add an underscore. If it contains illegal characters, like : or \, we re-map that character into unicode private use area. Signed-off-by: David Oberhollenzer

libsqfs: add a threshold for extended directory inodes with index

2024-01-24T08:56:10+00:00

mksquashfs generates extended inodes if a directory contains 256 entries. libsquashfs so far only generated extended inodes if there is no other way to encode it. Mimic the behaviour of mksquashfs by adding a threshold. For this to work, the "sqfs_inode_set_xattr_index" function has to be changed to not immediately try to demote inodes to basic types. The fstree serialization is modified to do that itself if the index is 0xFFFFFFFF and the target is not a directory inode. Signed-off-by: David Oberhollenzer

Move gensquashfs specific code from libfstree to gensquashfs

2022-11-22T13:45:32+00:00

The "from dir" and from "from file" code, as well as the "sort file" code is specific to gensquashfs, so move them there and the test cases as well. The medium term idea is to reduce libfstree to a stub, merge it into the generic writer and ultimately hoist that into libsquashfs. Signed-off-by: David Oberhollenzer

Get rid of the built-in copy of LZ4

2022-11-22T07:17:44+00:00

On Linux or BSD distributions we have a native version installed via package manager. On Windows, we can just build it from source like the other libraries. Signed-off-by: David Oberhollenzer

libsqfs: Fix an overzealous bounds check in the block processor

2022-11-18T15:21:12+00:00

When (during fragment deduplication) a fragment block is read back from disk and unpacked, it can happen that it is _exactly_ the given block size. The bounds check did '>=' instead of '>' and failed in that case with a "data corruption" error. Signed-off-by: David Oberhollenzer
