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>

2015-01-29ntpd: get rid of G.initial_poll_completeDenys Vlasenko
This speeds up syncing - now happens only just two replies from a peer. Especially useful for "ntpd -q". Shouldn't have ill effects: if we chose a bad peer, we will discover it later and switch to another one. The code is even smaller this way.

2015-01-27dhcpd: fix an improper widening conversionDenys Vlasenko
We wanted to detect when tv_sec = unsigned1 - unsigned2 underflows by looking at tv_sec's sign. But if tv_sec is long and it is wider than unsigned, we get unsigned -> long conversion which is in this case never negative. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2015-01-07vi: fix reading of file after last lineRon Yorston
If the :r command is used to read a file after the last line of the buffer the last line of the buffer and the first line of the file are joined. An extra blank line appears at the end of the buffer. file 1 file 1 file 1file 2 file 2 file 2 ~ ~ The insertion point is normally at the start of the line following the specified line. When the specified line is the last one the next_line function baulks at moving to the non-existent following line.
