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

libsqfs: Initialize the return value in sqfs_compressor_create

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

Initialize the output compressor pointer to NULL, so if the function fails, the value is propperly initialized to a NULL pointer instead of relying on the function user to initialize it. Signed-off-by: David Oberhollenzer

Add a single, central base64 decoder

2022-11-17T23:58:13+00:00

Similar to the hex blob decoder, we need this once for tar and once for the filemap xattr parser. Simply add a single, central implementation to libutil, with a simple unit test, and then use it in both libtar and gensquashfs. Signed-off-by: David Oberhollenzer

Add a single, central hex blob decoder

2022-11-17T23:58:07+00:00

Since we need it twice (once for tar, once for the filemap xattr parser), add a single, central implementation to libutil, add a unit test for that implementation and then use it in both libtar and gensquashfs. Signed-off-by: David Oberhollenzer

Only use available CPUs

2022-11-04T12:03:23+00:00

Not all CPUs may be available for the current process. Some CPUs may be offline, others may not be included in the process affinity mask. In such cases too many threads will be created, which will then compete unnecessarily for CPU time. Use sched_getaffinity() to determine the correct number of threads to create.
