MFC r228744 [1]: Merge vendor revision 3723: Fixes extraction of Zip entries that use length-at-end without specifying either the compressed or uncompressed length. In particular, fixes bsdtar extraction of such files. Reported by: Patrick Lamaiziere (freebsd-stable@) MFC r228745: Update libarchive, tar and cpio to version 2.8.5 The following additional vendor revisions are applied: Revision 3740: Use archive_clear_error() to clear the error markers. Obtained from: http://code.google.com/p/libarchive MFC r228748: Sync libarchive with vendor branch release/2.8: 3730: Fix issue 174 (Windows path names, not relevant for FreeBSD) 3734: Merge r1989: archive_clear_error should set errno to 0. 3735: Merge r3247 from trunk: Clear errors before returning from archive_read_support_format_all() 3799: Check the position before dereferencing the pointer. This avoids dereferencing one byte past the end of a string 3824: Merge r3823 from trunk for issue 199 (hang in iso9660 reading) Obtained from: http://code.google.com/p/libarchive

Fix cpio on ARM.

Import additional bugfix for reading and extracting makefs-created

2011-09-02T13:03:56Z

ISO images with tar. Vendor revision 3648 (merge of 3647): Additional fix to issue 168 because the change of r3642 was not sufficient. - Make sure "CL" entry appear after its "RE" entry which the "CL" entry should be connected with. - Give consideration to the case that the top level "RE" entry has already been exposed outside before its tree.

Import bugfix for reading and extracting of FreeBSD ISO images with tar.

Upstream revision 3645 (merge of 3642): Change the mechanism handling a rr_moved directory, which is Rockridge extension that can exceed the limitation of a maximum directory depth of ISO 9660. - Stop reading all entries at a time. - Connect "CL" entry to "RE" entry dynamically, which "CL" and "RE" have information to rebuild a full directory tree. - Tweak some related tests since we use Headsort for re-ordering entries and it cannot make a steady order when the keies of the entries are the same. http://code.google.com/p/libarchive/issues/detail?id=168 Reviewed by: kientzle Approved by: re (kib) Obtained from: libarchive (release/2.8, svn rev 3645) MFC after: 3 days

Partial merge of 2431 from trunk: Retry writes on EINTR. This should fix the SIGINT handler in bsdtar. Note: The rest of r2431 can't be merged, since it interacts with a big write-side rearchitecture. PR: bin/149409 Reviewed by: kientzle Approved by: re (kib) MFC after: 3 days

Add compatibility for ISO images created with unfixed makefs that

2011-08-07T08:42:36Z

violated ECMA-119 (ISO9660): allow reserved4 to be 0x20 in PVD. This allows tar to read FreeBSD distribution ISO images created with makefs prior to NetBSD bin/45217 bugfix (up to 9.0-BETA1). In addition, merge following important bugfixes from libarchive's release/2.8 branch: Revision 2812: Merge 2811 from trunk: Don't try to verify that compression-level=0 produces larger results than the default compression, since this isn't true for all versions of liblzma. Revision 2817: Merge 2814 from trunk: Fix Issue 121 (mtree parser error) http://code.google.com/p/libarchive/issues/detail?id=121 Revision 2820: Fix issue 119. Change the file location check that a file location does not exceed volume block. New one is that a file content does not exceed volume block(end of an ISO image). It is better than previous check even if the issue did not happen. While reading an ISO image generated by an older version of mkisofs utility, a file location indicates the end the ISO image if its file size is zero and it is the last file of all files of the ISO image, so it is possible that the location value is the same as the number of the total block of the ISO image. http://code.google.com/p/libarchive/issues/detail?id=119 Revision 2955: Issue 134: Fix libarchive 2.8 crashing in archive_write_finish() when the open has failed and we're trying to write Zip format. http://code.google.com/p/libarchive/issues/detail?id=134 Revision 2958: Followup on Issue 134: 1) Port test_open_failure to libarchive 2.8 branch to test the problem reported in Issue 134. This test also shows that archive_read_open() sometimes fails to report open errors correctly. 2) Fix the bug in archive_read.c 3) Comment out the tests that close functions are invoked promptly when open fails; that's fully fixed in libarchive 3.0, but I don't think it's worth fixing here. Revision 3484: Use uintmax_t with %ju Revision 3487: Fix issue 163. Correctly allocate enough memory for a input buffer saved. http://code.google.com/p/libarchive/issues/detail?id=163 Revision 3542: Merge 2516, 2536 from trunk: Allow path table offset values of 0 and 18, which are used by some ISO writers.

libarchive is mixing libmd and libcrypto -- correct to use one or the other.
