Here's what the different archivers do when asked to create a tar file without entries: $ uname -v NetBSD 6.0.1 (GENERIC) $ gtar --version | head -1 tar (GNU tar) 1.26 $ bsdtar --version bsdtar 2.8.4 - libarchive 2.8.4 $ : >zero.tar $ perl -e 'print "\0" x 10240' >tenk.tar $ sha1 zero.tar tenk.tar SHA1 (zero.tar) = da39a3ee5e6b4b0d3255bfef95601890afd80709 SHA1 (tenk.tar) = 34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c $ : | tar cf - -T - | sha1 da39a3ee5e6b4b0d3255bfef95601890afd80709 $ : | gtar cf - -T - | sha1 34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c $ : | bsdtar cf - -T - | sha1 34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c So NetBSD's native tar creates an empty file, while GNU tar and bsdtar both give us 10KB of NULs -- just like git archive with an empty tree. Now let's see how the archivers handle these two kinds of empty tar files: $ tar tf zero.tar; echo $? tar: Unexpected EOF on archive file 1 $ gtar tf zero.tar; echo $? gtar: This does not look like a tar archive gtar: Exiting with failure status due to previous errors 2 $ bsdtar tf zero.tar; echo $? 0 $ tar tf tenk.tar; echo $? tar: Cannot identify format. Searching... tar: End of archive volume 1 reached tar: Sorry, unable to determine archive format. 1 $ gtar tf tenk.tar; echo $? 0 $ bsdtar tf tenk.tar; echo $? 0 NetBSD's tar complains about both, bsdtar happily accepts any of them and GNU tar doesn't like zero-length archive files. So the safest course of action is to stay with our block-of-NULs format which is compatible with GNU tar and bsdtar, as we can't make NetBSD's native tar happy anyway. We can simplify our test, however, by taking tar out of the picture. Instead of extracting the archive and checking for the non-presence of files, check if the file has a size of 10KB and contains only NULs. This makes t5004 pass on NetBSD and OpenBSD.

| * | t5004: ignore pax global header fileRené Scharfe2013-05-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Versions of tar that don't know pax headers -- like the ones in NetBSD 6 and OpenBSD 5.2 -- extract them as regular files. Explicitly ignore the file created for our global header when checking the list of extracted files, as this is normal and harmless fall-back behaviour. This fixes test 3 of t5004 on these platforms.

This became a window for use-after-free() in abe601b (sha1_file: remove recursion in unpack_entry, 2013-03-27), as follows: Before abe601b, we got the 'base' from cache_or_unpack_entry(..., 0); keep_cache=0 tells it to also remove that entry. So the 'base' is at this point not cached, and freeing it in the error path is the right thing. After abe601b, the structure changed: we use a three-phase approach where phase 1 finds the innermost base or a base that is already in the cache. In phase 3 we therefore know that all bases we unpack are not part of the delta cache yet. (Observe that we pop from the cache in phase 1, so this is also true for the very first base.) So we make no further attempts to look up the bases in the cache, and just call add_delta_base_cache() on every base object we have assembled. But the !delta_data error path remained unchanged, and now calls free() on a base that has already been entered in the cache. This means that there is a use-after-free if we later use the same base again. So remove that free(); we are still going to use that data.
