which is not really there!

2007-06-20do not do utime() on links, it acts on link targets, and we don't want that.Denis Vlasenko
rename link_name to link_target, less confusing this way.

2006-11-26tar: correctly skip (and warn about) pax headers.Denis Vlasenko
plug memory leak. save 50 bytes. Wooohooo! we finally can unpack kernel tarballs!

2006-11-24tar: buglet fixDenis Vlasenko
2006-11-24tar: fix and sanitize handling of long filenames/linknamesDenis Vlasenko
(GNU extensions 'K' and 'L'). We correctly handle them when untarring now, but unfortunately we still don't use them when tarring! That stupid 100 char limit is still there! The biggest problem is that we don't support 'pax' tar format. Linux kernel tarballs are in this format... shame
2006-11-24header_verbose_list: stop truncating file size in listingDenis Vlasenko
2006-11-24tar:Denis Vlasenko
* unpack: handle tar header fields which are not NUL terminated * pack: handle 4+GB files correctly * pack: refuse to store 101+ softlinks (was truncating link target name) * pack: mask mode with 07777
