* 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. Basile2012-12-199-9/+30
| | | | | | | | | | | | | | | 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.

* build system: stop .eh_frame generationDenys Vlasenko2012-09-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | From Rich Felker: By default, modern GCC generates DWARF2 debug/unwind tables in the .eh_frame section of the object files/binaries. This adds significant bloat (as much as 15%) to the size of the busybox binary, including the portion mapped/loaded into memory at runtime (possibly a big issue for NOMMU targets), and the section is not strippable with the strip command due to being part of the loaded program text. I've since done some further checking - both testing and asking the GCC developers about it - and it seems the solution is to add to the CFLAGS -fno-unwind-tables and -fno-asynchronous-unwind-tables. If debugging is disabled, this will prevent GCC from outputting DWARF2 tables entirely. But since busybox builds with -g by default, the interesting case is what happens then. I originally thought these options would break debugging, but they don't; instead, they tell GCC to output the DWARF2 tables in the .debug_frame section instead of the newish .eh_frame section (used for exception handling). With these options added, busybox_unstripped is still fully debuggable, and the final busybox binary loses the 15% bloat factor from the DWARF2 tables.
