2022-11-21filemap xattr: use sqfs_u8 data type for xattr value blobsDavid Oberhollenzer
The xattr values are not strings, they are arbitrary byte blobs. To be on the safe side tough, we should still allocate the space for the extra null byte and propperly initialize the buffer. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2022-11-18filemap xattr: use file istream from libio instead of stdio FILEDavid Oberhollenzer
The line-by-line reading function in the io library was specifically added for this kind of use case, so we don't have to handle trimming of lines, don't have to touch getline() and it's convoluted error handling (return value -1 could mean either EOF or error). The code that searches for '\n' and replaces it with '\0' can be removed as well and a memory leak involving "line" is removed along the way.

2020-04-27Cleanup/fix: gensquashfs: split directory scanning from xattr scanningDavid Oberhollenzer
On the one hand, this commit cleanes the code a bit by splitting the "scan directory contents" code from the "scan xattrs from directory contents" and moving the later in a seperate file. On the other hand, the xattr scanning is now done *after* the fstree is post processed, which includes sorting it. This way, the xattrs are always added in a deterministic, reproducible order.

2020-04-27gensquashfs: Add options to globally override UID/GID valuesDavid Oberhollenzer
A common use case for mksquashfs is to simply pack a directory and set a magic option to force all user/group IDs to root. This commit adds similar options to gensquashfs to maek it better suited as a direct replacement for packing an input directory. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-04-27Cleanup directory structure of the binary programsDavid Oberhollenzer
Instead of having the binary programs in randomly named subdirectories, move all of them to a "bin" subdirectory, similar to the utility libraries that have subdirectories within "lib" and give the subdirectories the propper names (e.g. have gensquashfs source in a directory *actually* named "gensquashfs").
