2015-02-02gzip: do not store timestamp in gzip headerRich Felker
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. Signed-off-by: Rich Felker <dalias@libc.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

The performance and number of processes for a "depmod -a" with gzipped modules was abysmal. This patch adds a code path without fork, benefiting all users of xmalloc_open_zipped_read_close. "modinfo radeon.ko.gz", a single-file reader, got 30% faster. "depmod -a", which used to fork over 800 times, got 20% faster.

2013-09-10ar: read_num(): fix reading fields using the entire widthPeter Korsgaard
ar fields are fixed length text strings (padded with spaces). Ensure bb_strtou doesn't read past the field in case the full width is used. The fields are only read once, so the simplest/smallest solution to me seems to be to just pass the length to read_num() and then zero terminate the string before passing it to bb_strtou. This does mean that the fields MUST be read in reverse order, so some minor reshuffling was needed.
