| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mostly reverts commit bc9bbeb2b81001e8731cd2ae501c8fccc8d87cc7 "libarchive: do not extract unsafe symlinks unless $EXTRACT_UNSAFE_SYMLINKS=1" Users report that it is somewhat too restrictive. See https://bugs.busybox.net/show_bug.cgi?id=8411 In particular, this interferes with unpacking of busybox-based filesystems with links like "sbin/applet" -> "../bin/busybox". The change is made smaller by deleting ARCHIVE_EXTRACT_QUIET flag - it is unused since 2010, and removing conditionals on it allows commonalizing some error message codes. function old new delta create_or_remember_symlink - 94 +94 create_symlinks_from_list - 64 +64 tar_main 1002 1006 +4 unzip_main 2732 2724 -8 data_extract_all 984 891 -93 unsafe_symlink_target 147 - -147 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 1/2 up/down: 162/-248) Total: -86 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | Remove fake signal-handling codeRon Yorston2018-03-011-0/+2
| | | | | | | | | | | | | | | | | | Microsoft Windows has only limited support for signals. busybox-w32 initially papered over this fact by adding definitions for unsupported signals and signal-handling functions. Remove this fake code and deal with the consequences by excluding anything that fails to compile as a result.
* | tar: don't save file statusRon Yorston2018-02-261-0/+4
| | | | | | | | | | Since we're unable to track the file using its device/inode there's no need to obtain the file's status.

Problem reported by Yiorgos Adamopoulos. This regression was caused by the security patch installed 2006-11-20, which in turn came from Debian, which in turn apparently came from Thomas Biege of SuSe.
