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>

2018-03-29ifplugd: if SIOCSIFFLAGS fails with EADDRNOTAVAIL, don't dieStefan Agner
When using ifplugd on a RNDIS interface with monitor mode, using SIOCSIFFLAGS seems to fail with EADDRNOTAVAIL. Treat it the same as if iface disappeared again. This has been observed on a Tegra TK1 using Linux 4.14. There seem to be a race when the kernel is creating the device: ifplugd(usb0): started: BusyBox v1.24.1 (2018-03-27 09:47:48 CEST) ifplugd(usb0): interface doesn't exist, waiting ifplugd(usb0): interface appeared ifplugd(usb0): upping interface ifplugd(usb0): setting interface flags failed: Cannot assign requested address <exit> With this patch ifplugd is successful in upping the device the second time around: ifplugd(usb0): upping interface ifplugd(usb0): using SIOCETHTOOL detection mode ifplugd(usb0): interface appeared ifplugd(usb0): upping interface ifplugd(usb0): setting interface flags failed: Cannot assign requested address ifplugd(usb0): interface appeared ifplugd(usb0): upping interface ifplugd(usb0): using SIOCETHTOOL detection mode ifplugd(usb0): link is up ifplugd(usb0): executing '/etc/ifplugd/ifplugd.usb.action usb0 up' ifplugd up ifplugd(usb0): exit code: 0 function old new delta up_iface 120 127 +7 Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2012-12-19CONFIG_PID_FILE_PATH: new configuration option for pidfile pathsAnthony G. Basile
We set a default path for the directory where pidfiles are create when FEATURE_PIDFILE is selected. The default has no effect on applets which must specify a pidfile path on the command line to run, and it can be overridden by applets which optionally allow the user to specify the pidfile path. We also add pidfile write/remove support for klogd, ntpd and watchdog. For syslogd, we add a missing remove_pidfile() for better cleanup on daemon exit. Signed-off-by: Anthony G.
