2019-04-30Optionally re-introduce bb_info_msg()James Byrne
Between Busybox 1.24.2 and 1.25.0 the bb_info_msg() function was eliminated and calls to it changed to be bb_error_msg(). The downside of this is that daemons now log all messages to syslog at the LOG_ERR level which makes it hard to filter errors from informational messages. This change optionally re-introduces bb_info_msg(), controlled by a new option FEATURE_SYSLOG_INFO, restores all the calls to bb_info_msg() that were removed (only in applets that set logmode to LOGMODE_SYSLOG or LOGMODE_BOTH), and also changes informational messages in ifplugd and ntpd. The code size change of this is as follows (using 'defconfig' on x86_64 with gcc 7.3.0-27ubuntu1~18.04) function old new delta bb_info_msg - 182 +182 bb_vinfo_msg - 27 +27 static.log7 194 198 +4 log8 190 191 +1 log5 190 191 +1 crondlog 45 - -45 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 3/0 up/down: 215/-45) Total: 170 bytes If you don't care about everything being logged at LOG_ERR level then when FEATURE_SYSLOG_INFO is disabled Busybox actually gets smaller: function old new delta static.log7 194 200 +6 log8 190 193 +3 log5 190 193 +3 syslog_level 1 - -1 bb_verror_msg 583 581 -2 crondlog 45 - -45 ------------------------------------------------------------------------------ (add/remove: 0/2 grow/shrink: 3/1 up/down: 12/-48) Total: -36 bytes Signed-off-by: James Byrne <james.byrne@origamienergy.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-02-27udhcpc: don't exit after backgrounding on -n -bAndrey Mazo
Currently, running "udhcpc -n -b" causes udhcpc to go to background and then exit after some time unless a lease is obtained. It's not very useful to do so as the calling process doesn't know if the lease was obtained or not anyway. The code actually tries to favor "-b" over "-n", but doesn't clear "-n" flag while clearing "-b" after backgrounding. So, clear "-n" flag after going into background. This effectively makes "-b" override "-n" completely and "-n -b" behave the same as "-b". This allows to override default "-n" option, passed to udhcpc by ifupdown, without recompiling busybox.
