2019-08-23Some simple search/replace cases for allocationDavid Oberhollenzer
This commit exchanges some malloc(x + y * z) patterns that can be found with a simple git grep and are obvious for the new wrappers. 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.

2019-07-10Make coverity happyDavid Oberhollenzer
The string is actually always null-terminated, since the calloc above adds one more byte than what we tell readlink about. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-01Fix alloca'd memory being freed in fstree_from_dirDavid Oberhollenzer
Most code path that use 'extra' allocate it using calloc/malloc/strdup and then converge into a common path that uses free() on extra. This commit removes a stray one that uses alloca for symlink targets, so we don't free() a stack buffer further down in the common path. Bug found using scan-build.

2019-06-19Cleanup fstree codeDavid Oberhollenzer
Replace default_$FIELD with a struct stat. Merge the rest of add_node/add_file into mknode and add by path+stat. Expose the mknode function and replace all the duplicated node pointer arithmetic magic with a call to mknode. Plus a generic cleanup by utlizing new util functions.
