2020-01-29vi: fixes to string search in colon commands, closes 10321Ron Yorston
Handling of string searches in colon commands (e.g ':/pat1/,/pat2/cmd') differ from standard vi: - As reported in bug 10321 such searches can't be repeated using the 'n' command. This is because the last search pattern isn't updated. - The search also can't be repeated using the command '://' because an empty search pattern doesn't imply the use of the last search pattern. - Such searches should start on the line after the current line, otherwise '://' never moves to the next occurrence of the pattern. This can also affect other cases where line ranges are specified using search patterns. Fix these various issues. function old new delta get_one_address 325 342 +17 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2020-01-29ash: improve expandstr()Ron Yorston
The dash maintainer recently posted a fix for issues with expanding PS1. These had already been fixed differently in BusyBox ash. Borrow a couple of improvements: - Use a single call to setjmp() to trap errors in both readtoken1() and expandarg(). - In case of error set the prompt to the literal value of PS1 rather than the half-digested nonsense in stackblock() which might include ugly control characters. function old new delta expandstr 353 300 -53 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2020-01-29syslogd: add config option to include milliseconds in timestampsPeter Korsgaard
For some use cases, having logs with more than 1 second accuracy can be helpful. Add an option to include milliseconds when adding a timestamp in HH:MM:SS.mmm format, similar to syslog-ng with fraq_digits(3) or journalctl -o short-precise. For simplicity, abuse the remaining space in the buffer used by ctime to add the millieconds (overwriting year). function old new delta timestamp_and_log 401 448 +47 Signed-off-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-11-17chgrp: correct the usage for non-desktop chgrp callsLiu, Shuang (ADITG/ESM)
When IF_DESKTOP is not defined, chown and chgrp only takes option -R -h, However the usage output of chgrp is wrong: $ ./busybox.nosuid chown Usage: chown [-Rh]... USER[:[GRP]] FILE... $ ./busybox.nosuid chgrp Usage: chgrp [-RhLHP]... GROUP FILE... $ ./busybox.nosuid chgrp -H group dummy chgrp: invalid option -- 'H' Usage: chgrp [-RhLHP]... GROUP FILE... The chgrp is now a wrapper of chown, so the recognized options shall be the same. This is introduced by 34425389e09353a8dacdd6b23a62553f699c544c I would expect the correct behavior shall be the same as chown. So suggest the below patch, the behavior shall be: $ ./busybox.nosuid chgrp Usage: chgrp [-Rh]... GROUP FILE...

2019-10-30ntpd: decrease MIN_FREQHOLD by 2, increase "penalty" for largish offset x2Denys Vlasenko
> 2018-07-25: > ntpd: increase MIN_FREQHOLD by 3 > This means we'll start correcting frequency ~5 minutes after start, > not ~3.5 ones. > With previous settings I still often see largish ~0.7s initial offsets > only about 1/2 corrected before frequency correction kicks in, > resulting in ~200ppm "correction" which is then slowly undone. Review of real-world results of the above shows that with small initial offsets, freq correction can be allowed to kick in sooner, whereas with large (~0.8s) offsets, we still start freq correction a bit too soon. Let's rebalance this a bit. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-10-27nslookup: handle replies without RRsJo-Philipp Wich
Under some circumstances, a DNS reply might contain no resource records, e.g. when a valid domain is queried that does not have records of the requested type. Example with nslookup from BIND dnsutils: $ nslookup -q=SRV example.org Server: 10.11.12.13 Address: 10.11.12.13#53 Non-authoritative answer: *** Can't find example.org: No answer Currently the busybox nslookup applet simply prints nothing after the "Non-authoritative answer:" line in the same situation. This change modifies nslookup to either print "Parse error" or "No answer" diagnostics, depending on the parse_reply() return value. function old new delta send_queries 1676 1711 +35 Signed-off-by: Jo-Philipp Wich <jo@mein.io> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-10-14config: PID_FILE_PATH required for FEATURE_CROND_SPECIAL_TIMESJames Byrne
When crond is built with FEATURE_CROND_SPECIAL_TIMES enabled, it creates a file called 'crond.reboot' at CONFIG_PID_FILE_PATH, but if FEATURE_PIDFILE is disabled, this will be an empty string and the file will be created in the root directory, which is undesirable. This commit makes PID_FILE_PATH depend on FEATURE_CROND_SPECIAL_TIMES as well as FEATURE_PIDFILE so that you get sensible behaviour in crond when FEATURE_PIDFILE is switched off.
