The following tests where done on 8.4 / 9.3 (amd64) Test case 1 =============== $ cd $space $ fetch ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/10.1-RC4/base.txz $ tar xf base.txz ^./etc $ mkdir t1 $ tar -C t1/ -xf base.txz ^./etc $ diff -Nru etc/ t1/etc/ => no diff but in both times etc/hosts.allow is corrupted Test case 2: =============== $ mkdir t2 $ tar -C t2/ -xf base.txz $ diff -Nru etc/ t2/etc/ Files etc/hosts.allow and t2/etc/hosts.allow differ The file t2/etc/hosts.allow is extracted correct, no corruption Now use libarchive / tar from releng/10.1 on the the 8.4 system 1. backup /usr/lib/libarchive.* 2. co, patch, build libarchive and bsdtar from releng/10.1 source $ mkdir space && cd $space $ svn co http://svn.freebsd.org/base/releng/10.1 $ patch -d 10.1 < libarchive.diff $ cd $space/10.1/lib/libarchive $ make MK_ICONV=no obj $ cp /usr/obj/.../libarchive.so* /usr/obj/.../libarchive.a /usr/lib/ $ cd $space/10.1/usr.bin/tar $ make MK_ICONV=no obj $ make MK_ICONV=no Copy the resulting /usr/obj/.../bsdtar to the space from test 1 Test case 3: ============== $ rm -rf etc $ ./bsdtar xf base.txz ^./etc $ diff -Nru etc t2/etc/ => The file etc/hosts.allow is extracted without corruption A copy of a corrupt hosts.allow file and the patch against 8.4 can be found here http://people.freebsd.org/~ohauer/diffs/libarchive/ -- You are receiving this mail because: You are the assignee for the bug.
