Generate linear file list in fstree

2019-07-25T20:10:24+00:00

Instead of doing DFS on the fly in gensquashfs, churn out a linked list of all files in an archive. Future improvements in packing strategies can go into this file. This can also be usefull for other purposes in the future, such as file deduplication or as a work queue for the unpacker. Signed-off-by: David Oberhollenzer

2019-07-25T17:16:11+00:00

This commit attempts to make the generic table writer more readable. A few changes are made, including heap allocation of the block list. Signed-off-by: David Oberhollenzer

Fix processing of tar mtime on 32 bit systems

2019-07-24T16:10:34+00:00

struct stat uses time_t to store time values. On some 32 bit systems, this may be a 32 bit integer. This patch adds a broken-out 64 bit time value to tar_header_decoded_t and makes sure to clamp the value to +/- (2^32 - 1) if required when writing it back to a struct stat.

Enable largefile support

2019-07-24T07:16:16+00:00

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. Signed-off-by: Matt Turner Signed-off-by: David Oberhollenzer

Add a way to optionally keep the original time stamps

2019-07-22T15:12:45+00:00

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.

Cleanup xattr handling

2019-07-21T13:44:02+00:00

- Store them in a struct instead of a hacky uint64_t with magic shifts - Split up key/value pair write function to write_key and write_value - Move the size accounting into those functions respectively Signed-off-by: David Oberhollenzer

Keep track of xattr key & value references AFTER deduplication

2019-07-21T11:30:34+00:00

This commit adds a reference count functionality to the string table implementation and uses this functionality in the fstree code to count how often each key and value is referenced by the deduplicated Xattr blocks. This is needed to support deduplication through out-of-band storage of xattrs. Signed-off-by: David Oberhollenzer
