2017-05-30openrc-init: fix buffer overflow in init.ctlSergei Trofimovich
How to reproduce 1-byte overflow: ``` $ FEATURES=-test CFLAGS="-fsanitize=address -O0 -ggdb3" emerge -1 openrc ================================================================= ==1==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7fff0efd8710 at pc 0x000000402076 bp 0x7fff0efd7d50 sp 0x7fff0efd7d40 WRITE of size 1 at 0x7fff0efd8710 thread T0 #0 0x402075 (/sbin/openrc-init+0x402075) #1 0x3cf6e2070f in __libc_start_main (/lib64/libc.so.6+0x3cf6e2070f) #2 0x4013b8 (/sbin/openrc-init+0x4013b8) Address 0x7fff0efd8710 is located in stack of thread T0 at offset 2432 in frame #0 0x401cfb (/sbin/openrc-init+0x401cfb) This frame has 3 object(s): [32, 160) 'signals' [192, 344) 'sa' [384, 2432) 'buf' <== Memory access at offset 2432 overflows this variable HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext (longjmp and C++ exceptions *are* supported) SUMMARY: AddressSanitizer: stack-buffer-overflow ??:0 ?? ``` The problem here is in the code handling reads from 'init.ctl': ``` int main(int argc, char **argv) { ... char buf[2048]; for (;;) { /* This will block until a command is sent down the pipe... */ fifo = fopen(RC_INIT_FIFO, "r"); count = fread(buf, 1, 2048, fifo); buf[count] = 0; ... } ``` `buf[count] = 0;` writes outside the buffer when `fread()` returns non-truncated read. This fixes #138.
2017-05-30rc-logger.c: fix crash on fclose(NULL) (#137)Sergei Trofimovich
Only close the log if we successfully opened it. Reported-by: Brian Evans <grknight@gentoo.org> Tested-by: Brian Evans <grknight@gentoo.org> Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
2017-05-22openrc-shutdown: add dry-run optionWilliam Hubbs
2017-05-22openrc-shutdown: move to single user mode by defaultWilliam Hubbs
To be more compatible with sysvinit, move to single user mode if no options are specified on the command line.
2017-05-22init: add ability to switch to single user modeWilliam Hubbs
2017-05-19add kill_all helperWilliam Hubbs
This is similar to the sysvinit killall5 utility. It should only be used in service scripts, so it will not be installed in the path. This closes #129.
2017-05-15rc_status: calculate time differences in time_t and display seconds in uptimeWilliam Hubbs
2017-05-12supervise-daemon: save start time and respawn count before dropping privsWilliam Hubbs
2017-05-11rc-status: show uptimes and respawn counts for supervised daemonsWilliam Hubbs
2017-05-11fix to_time_t to honor dstWilliam Hubbs
2017-05-11fix from_time_t functionWilliam Hubbs
2017-05-11Move time_t conversions to rc-misc.c so they can be sharedWilliam Hubbs
2017-05-11supervise-daemon: save start time and respawn countWilliam Hubbs
This will allow rc-status to display an uptime and restart count for supervised processes.
2017-05-11supervise-daemon: fix our status when we give up on the child processWilliam Hubbs
2017-05-10supervise-daemon:create multiple options from --respawn-limitWilliam Hubbs
This creates --respawn-delay, --respawn-max and --respawn-period. It was suggested that it would be easier to follow if the options were separated. This is for #126.
2017-05-09supervise-daemon: add a --respawn-limit optionWilliam Hubbs
Allow limiting the number of times supervise-daemon will attempt to respawn a daemon once it has died to prevent infinite respawning. Also, set a reasonable default limit (10 times in a 5 second period). This is for issue #126.
2017-04-29supervise-daemon: mark all open file descriptors FD_CLOEXECWilliam Hubbs
2017-04-29supervise-daemon:remove the controlling tty in the supervisorWilliam Hubbs
2017-04-29supervise-daemon: fix access to tty_fd and devnull_fdWilliam Hubbs
Both the child and supervisor need access to these file descriptors.
2017-04-29supervise-daemon: mark the service started when the supervisor is activeWilliam Hubbs
2017-04-17init: send term/kill signals as final step of shutdownWilliam Hubbs
2017-04-13init: fix signal handlingWilliam Hubbs
The only signals we handle are SIGINT and SIGCHLD, so block all others and unblock them in the child process before we start a rurnlevel.
2017-04-12init: add re-exec capabilityWilliam Hubbs
This will allow the re-execution of the init process after upgrading OpenRC.
2017-04-07Add attribution to openrc-init.c and openrc-shutdown.cWilliam Hubbs
2017-04-06add init processWilliam Hubbs
openrc-init.c and openrc-shutdown.c are based on code which was written by James Hammons <jlhamm@acm.org>, so I would like to publically thank him for his work.
2017-04-03start-stop-daemon: warn if calling --start with --retry or --stop with --waitAustin English
This fixes #122
2017-02-17Move deptree2dot to the support folderWilliam Hubbs
Since deptree2dot and the perl requirement are completely optional, we can move this tool to the support folder. This gives the user the option of using it if they have perl installed, and means we do not have an optional runtime dependency on perl. Documentation for this tool has also been added to the support folder. X-Gentoo-Bug: 600742 X-Gentoo-Bug-URL: https://bugs.gentoo.org/show_bug.cgi?id=600742
2017-01-25start-stop-daemon: allow all standard signalsDoug Freed
Also we define the signalpair_item macro. This fixes #113. X-Gentoo-Bug: 604986 X-Gentoo-Bug-URL: https://bugs.gentoo.org/show_bug.cgi?id=604986
2017-01-04mountinfo: make the path to /proc/mounts a constantWilliam Hubbs
This path should not be hard coded in the open call. Linux prior to 2.4.19 did not have /proc/self/mounts, so for now I'm making this value /proc/mounts everywhere, but that may change to /proc/self/mounts on linux; I'm not sure we should care about <2.4.19.

2016-10-11do_service: Initialize idx to 0Sven Wegener
If index is not explicitly specified for service_started_daemon, it will look for daemons by random index. This fixes #100.
2016-09-30openrc-run: fix double freeDoug Freed
2016-09-19Revert "Disable parallel startup in interactive mode"William Hubbs
This reverts commit 8b4fc05ff2645b2ecb0f153492f72dd8b39ba431. The original commit did not explain why this feature was disabled, and I now have a request to enable it. This fixes #24.
2016-09-16rc-misc: allow EINFO_VERBOSE through tooDoug Freed
2016-09-14rc-misc: Allow EINFO_COLOR through env_filter()Doug Freed
This allows rc-service -C <service> <action> to properly not print color messages. Fixes #93

2016-07-31librc: fix Docker auto detectionWilliam Hubbs
The original auto detection of Docker containers assumed the presence of a container environment variable. However, Docker-1.12 does not implement this, and I'm not sure which versions of docker implemented it. The new test is for the presence of a file named .dockerenv in the root directory.
2016-07-26start-stop-daemon: Add SSD_IONICELEVELKenneth Lakin
This is the disk IO counterpart to SSD_NICELEVEL. Modified by William Hubbs to add the variable to the start-stop-daemon man page. This fixes #69.
2016-07-24rc-logger: refuse to cat TMPLOG into itselfDoug Freed
This prevents an infinite loop in case somebody decides to set rc_log_path to match TMPLOG.
2016-07-18rc-status: add -m/--manual option to show manually started servicesWilliam Hubbs
X-Gentoo-Bug: 585906 X-Gentoo-Bug-URL: https://bugs.gentoo.org/show_bug.cgi?id=585906
