* syslogd: minor tweaks to textMike Frysinger2016-04-041-2/+2

* Fix compiling with musl's utmp stubsKylie McClain2016-02-011-1/+0
| | | | | | | | | | | | | | | | | | | This patch fixes compiling busybox with FEATURE_UTMP and _WTMP enabled. musl, while not really support utmp/wtmp, provides stub functions, as well as variables such as _PATH_UTMP, so that programs using utmp or wtmp can still compile fine. My reasoning for this patch is that on Exherbo, I'm currently trying to get us to be able to use the same busybox config file for both glibc and musl systems, using utmp/wtmp on systems that support it, and using the stubs on musl without needing two different configs. As of latest musl git, it provides all utmp functions needed; 1.1.12 doesn't, but I sent a patch to Rich to add the utmp{,x}name functions expected to exist, which was merged into musl upstream.

* syslogd: make "reopen log file every second" logic work for multiple logsJoshua Judson Rosen2014-07-031-6/+7
| | | | | | | | | | | Move last_log_time from a single global to *each logFile_t* so that we can actually apply the logic to every log-file in multi-file configurations, rather than working only for the first file written in each 1-second interval and then leaving the others connected to possibly wrong files.

* syslogd: add option to log to Linux kernel printk bufferPeter Korsgaard2013-01-062-1/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Why invent our own shared memory circular buffer when the kernel has a perfectly fine one already? This can be used as a smaller/simpler alternative to the syslogd IPC support (as IPC shmem/klogd/logread aren't needed), while also allowing centralised logging of everything (kernel messages, userspace bootup and syslog) when used together with ttyprintk. Notice that kernel 3.5+ is needed to store syslog facility in printk buffer, otherwise only the priority is stored. bloat-o-meter compared to IPC+klogd+logread: function old new delta get_linux_version_code - 84 +84 lbb_prepare 25 90 +65 applet_nameofs 6 - -6 static.stdout@@GLIBC_2 8 - -8 applet_names 23 9 -14 bb_msg_standard_output 16 - -16 init_sem 18 - -18 xatoull_range 19 - -19 overlapping_strcpy 21 - -21 init_data 56 32 -24 applet_main 24 - -24 main 124 99 -25 full_write2_str 26 - -26 error_exit 26 - -26 bb_basename 30 - -30 sem_up 32 - -32 interrupted 35 - -35 fflush_stdout_and_exit 38 - -38 bb_banner 46 - -46 find_applet_by_name 59 - -59 bb_signals_recursive_norestart 90 - -90 run_applet_no_and_exit 104 - -104 timestamp_and_log 651 523 -128 syslogd_main 798 581 -217 xstrtoull_range_sfx 267 - -267 run_applet_and_exit 432 - -432 klogd_main 490 - -490 logread_main 508 - -508 .rodata 1870 937 -933 bb_common_bufsiz1 8193 - -8193 ------------------------------------------------------------------------------ (add/remove: 2/26 grow/shrink: 1/6 up/down: 149/-11829) Total: -11680 bytes Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* CONFIG_PID_FILE_PATH: new configuration option for pidfile pathsAnthony G. Basile2012-12-192-1/+7
| | | | | | | | | | | | | | | 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.

* syslogd: work around rename() not renaming hardlinks to themselvesChristian Engelmayer2011-10-281-0/+8
| | | | | | | | | | | | | | | | | | | | | Function log_locally() within the syslogd can potentially lock up when restarting the daemon after a power loss in case the unplanned shutdown hit the rename operation during logfile rotation. While POSIX requires the rename operation to be atomic, many file systems such as JFFS2 implement the rename operation in 2 steps by linking the new name followed by unlinking the original name. In case of a power loss during the rename the system can end up with /var/log/messages and /var/log/messages.0 being 2 hard links to the same file. When the syslog daemon restarts in such a situation it will rediscover the need to rotate the log files, however, POSIX also requires that rename does nothing and reports success in case oldpath and newpath are existing hard links to the same file. Looping through reopen: by (O_CREAT | O_APPEND), the daemon eternally reopens the same file without succeeding to rotate.
