tar writer: replace PAX headers with GNU extensions

2019-07-03T13:17:57+00:00

Some experiments seem to indicate that the various GNU extensions are more widely supported than their POSIX equivalents[1]. Possibly because they are easier to implement and possibly because of the wide spread use of GNU tar. This commit replaces the PAX writer in the write_tar_header implementation with a GNU extension based writer. The writer is also cleaned up by removing all global state. The record counter is moved outside into the tar2sqfs program and passed in as function argument.

Fix: don't blindly strcpy() the tar header name

2019-07-03T12:12:46+00:00

If the tar header name is exactely 100 bytes long, it does not have a trailing null byte. Using strlen/strcpy on it effectively concatenates the following fields contents to it. Signed-off-by: David Oberhollenzer

cleanup: split tar code up, remove some duplications

2019-07-01T11:23:36+00:00

This commit attempts to split some of the monolitic tar parsing code up into multiple functions in seperate files. Also, some code duplication (like reading a record into memory which was implemented twice) is removed. Signed-off-by: David Oberhollenzer

Fix double free in GNU tar sparse file parser

2019-07-01T09:46:40+00:00

The intention was to free the temporary object in addition to the list. Since the temp pointer is also used for iterating the list, this resulted in a double free instead of the intended. This commit fixes the double free by replacing the recycled variable based list free with the helper function intended to do this. Bug found using scan-build. Signed-off-by: David Oberhollenzer
