Denys Vlasenko	984b0a613a	libarchive: fix xmalloc_open_zipped_read_close() on NOMMU The somewhat new "unpack in memory" code was broken for xmalloc_open_zipped_read_close() on NOMMU: we seek back over signature, but then expect it to be already consumed. Stop seeking back in this case. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2016-06-20 11:06:42 +02:00

Rich Felker	7f7ade1964	gzip: do not store timestamp in gzip header Storing the original file's modification time in the output file is harmful (precludes deterministic results) and unlike official gzip, the busybox version provides no way to suppress this behavior; the -n option is silently ignored. Rather than trying to make -n work, this patch just removes the timestamp-storing functionality. It should be considered deprecated anyway; it's not Y2038-safe and gunzip ignores it by default. Per RFC 1952, 0 is the correct value to store to indicate that there is no timestamp.
