2021-03-25libfstree: Allow / as argument for "glob" and "dir" commandsDavid Oberhollenzer
This allows putting globbed files & directories into the filesystem root, as well as explicitly setting attributes of the root directory from the file lisiting. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2021-03-20Add libcompat fallback implementation for fnmatchDavid Oberhollenzer
This has basically been copied over from Musl and slightly modifed. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2021-02-19Fix: libfstree: add an assert the canonicalize_name return valueDavid Oberhollenzer
Since the canonicalize_name function only fails if the path contains ".." and the one we are constructing from the scanned fstree (built using canonicalized names), it should NEVER fail. However, coverity does get concerned, because we are checking the return value elesewhere. So do what we do at other, similar locations and add an assert().

2021-02-19fstree_from_file: Add fnmatch() pattern matching to file globbingDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2021-02-19fstree_from_file: Implement basic file globbingDavid Oberhollenzer
The base path is passed to the fstree_from_file function and in turn to the individual callbacks. The line parsing function is modified to allow '*' as mode, uid and gid for specifically marked callbacks. A glob callback is added that internally uses the fstree_from_dir scanning functions in combination with a filter callback. Directory scanning flags are parsed from the extra arguments before interpreting it as a path fragment. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-12-22Add hard link support to gensquashfs and tar2sqfsDavid Oberhollenzer
In libtar, set a special flag if the header is actually a hard link. In tar2sqfs, create a hard link node and skip the rest for hard links. Also refues to set the root attributes from a hard link, it may refere to a node that we have missed earlier, there is nothing else that we can do here. In fstree_from_file, add a "link" command for adding hard links. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-10-28Add macro for printf format specifier for size_tDavid Oberhollenzer
The MSVC runtime is a wierdo C89 platform with some cherry picked features from C99 (which does not include the "%zu" format specifier). This commit adds a macro with a size dependend format specifier to be used instead. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-10-07Cleanup: move libutil related headers to "util" sub directoryDavid Oberhollenzer

2019-09-29Cleanup: fstree_from_file does not need to change working directoryDavid Oberhollenzer
The file_info_t no longer stores the size or other such information, so there is no need to do a stat on the input file. This also means that gensquashfs no longer needs to change the working directory when using the function. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-27Add a header for platform compatibillity fluffDavid Oberhollenzer
- We don't have "endian.h" everywhere. On some BSDs its in sys and on some BSDs the macros have different names. - We definitely don't have sysmacros.h on non-Unix-like systems. - Likewise for sys/types.h, sys/stat.h and their contents.

2019-07-24cleanup: remove atime/ctime processing codeDavid Oberhollenzer
This commit removes all the code for parsing and processing atime/ctime and values and related test code. Caring about those is kind of pointless because squashfs can only store mtime in inodes. The only relevant place is when generating a struct stat from a squashfs inode or an fstree node. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-24Enable largefile supportMatt Turner
Requires that config.h be included before other headers, since the macro _FILE_OFFSET_BITS changes the definitions of things like 'struct stat'. I chose to simply include it at the top of every C file and at immediately after the double-inclusion guards of every header.

2019-07-22Add a way to optionally keep the original time stampsDavid Oberhollenzer
First of all, this commit adds a mod_time field to a tree node. When creating the tree node, the field is set from the struct stat. When scanning a directory, the time stamps from the input are used if set. Second, the libsqfs code that reads inodes is modified to store the mod_time from the inode in the fstree node and to write the tree node into a generated inode. Finally, tar2sqfs is modified to optionally keep the timestamps from the tar archive instead of setting defaults. gensquashfs is similarly modified to keep the input timestamps if specified. The result is as follows: - sqfs2tar will always carry the timestamps from the squashfs over to the tar ball. - tar2sqfs will set defaults, unless explicitly asked to preserve the mtime from the tar ball. - gensquashfs can optionally preserve the mtime from the input hierarchy it processes if only --pack-dir is specified.

2019-07-17fstree: add support for spaces in filenamesDavid Oberhollenzer
This commit adds a mechanism to fstree_from_file to support filenames with spaces in them by quoting the entire string. Quote marks can still be used inside file names by escaping them with a backslash. Back slashes (if that is your thing) can also be escaped.

2019-07-07Fix regression in fstree_from_file device node formatDavid Oberhollenzer
The format is documented as "<c|b> major minor" but the parser was accidentally changed to require a colon in between. Fixes: 9864ea5b2045f4bd72633152d71dd1c7f8b0b7f9 Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-06-22Cleanup: unify packdir/packfile based directory changes in gensquashfsDavid Oberhollenzer
This commit removes the packdir/packfile based directory setup magic from fstree_from_file and moves it to gensquashfs. Over there, the common parts are deduplicated. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-06-10gensquashfs: do pushd/popd when needed instead of chdirDavid Oberhollenzer
This commit replaces the chdir to the input directory with pushd/popd when building the fstree and again when packing files. This simplifies handling of other file paths given on the command line that have to be accessed and are relative to the original working directories. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-05-31gensquashfs: allow combining packdir and packfileDavid Oberhollenzer
If packdir and packfile are both specified, use packdir as alternate root. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-05-31gensquashfs: chdir into directory where the input file liesDavid Oberhollenzer
This makes path handling a lot easier. We no longer need to paste paths together to get input file relative paths, since we are in the same directory. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
