2018-12-27fix leading whitespacephilhofer
Clean up code indented with mixed tabs and spaces. No actual code changes. This fixes #280.
2018-12-27fix potential out-of-bounds readsphilhofer
readlink(3) does not nul-terminate the result it sticks into the supplied buffer. Consequently, the code rc = readlink(path, buf, sizeof(buf)); does not necessarily produce a C string. The code in rc_find_pid() produces some C strings this way and passes them to strlen() and strcmp(), which can lead to an out-of-bounds read. In this case, since the code already takes care to zero-initialize the buffers before passing them to readlink(3), only allow sizeof(buf)-1 bytes to be returned. (While fixing this issue, I fixed two other locations that used the same problematic pattern.) This fixes #270.
2018-12-24src/librc/librc-daemon.c: fix buffer overrun in pid_is_argvphilhofer
The contents of /proc/<pid>/cmdline are read into a stack buffer using bytes = read(fd, buffer, sizeof(buffer)); followed by appending a null terminator to the buffer with buffer[bytes] = '\0'; If bytes == sizeof(buffer), then this write is out-of-bounds. Refactor the code to use rc_getfile instead, since PATH_MAX is not the maximum size of /proc/<pid>/cmdline. (I hit this issue in practice while compiling Linux; it tripped the stack-smashing protector.) This is roughly the same buffer overflow condition that was fixed by commit 0ddee9b7d2b8dea810e252ca6a95c457876df120 This fixes #269.

2018-08-06librc: fix EACCES errno false-positive crashZac Medico
Use errno != EACCES to fix false-positive for non-root users with grsecurity kernels. Fixes: 37e29442721a ("librc: Add check for crashed state") This fixes #237

2018-05-22librc: Add check for crashed stateWilliam Hubbs
In rc_service_state,, call rc_service_daemons_crashed to check for a crashed daemon if the service is started.

2017-11-30Fix repeated dependency cache rebuild if clock skewedWill Miles
rc_deptree_update_needed would return early as soon as it found any file newer than the existing dependency cache. Unfortunately, the first file found may not be the newest one there; so the clock skew workaround in rc-misc:_rc_deptree_load would be given a timestamp that was still too old. This fix forces a full scan of all relevant files, so as to ensure that we return a timestamp that will allow the clock skew fix to operate. The runtime cost is no worse than the case where the cache is up to date (ie. we must check every possible file). This fixes #161.
2017-11-13rc_find_pids: namespace fixWilliam Hubbs
Ignore namespaces if there are errors reading either the pid namespace for the current process or the process we aare testing. This fixes https://github.com/openrc/openrc/issues/180.
2017-10-26rc_service_value_set: remove the option if NULL is the valueWilliam Hubbs
This allows the equivalent of "unsetting" a value for a service.

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.

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.
2016-07-14Remove the DEBUG_MEMORY macroWilliam Hubbs
This fixes #43.
2016-01-21librc: Complain when a real and virtual service have the same nameWilliam Hubbs
2016-01-19librc: handle rc_sys="prefix" even if we weren't built with a prefixDoug Freed
This probably isn't needed, but it mimics old behavior.
2016-01-19librc: fix handling the nothing special case for rc_sysDoug Freed
2016-01-19librc: move system detection code into rc_sys and use itDoug Freed
This fixes an issue where librc code was calling code that only existed in the rc binary. This reverts commits 8addd79 and 9f6e056 This fixes #75.
2016-01-18Revert "librc: fix librc-depend functions to call rc_sys"William Hubbs
This reverts commit 73482cf13a338051606788957cbd0031ac850c70.

2015-12-21Convert OpenRC to a centralized copyright/license structureWilliam Hubbs
In the past, OpenRC was a hybrid of a centralized and file-scope license/copyright structure. I followed the instructions from the Software Freedom Law Center [1] to convert to a Centralized structure where possible, for easier future maintenance.

2015-12-01librc: comsolidate rc_sys_v1 and rc_sys_v2 into rc_sysWilliam Hubbs
These functions were never meant to be used outside of OpenRC, and they were added when we thought we were going to do away with the automatic detection of subsystems. Since the autodetection is not going away, we can combine these functions into rc_sys.
2015-11-12Implement "want" dependencyIan Stakenvicius
The want dependency is similar to the use dependency. If a service script, for example called service1, adds "want service2" to its depend function, OpenRC will attempt to start service2, if it exists on the system, when service1 is started. However, service1 will start regardless of the status of service2. X-Gentoo-Bug: 406021 X-Gentoo-Bug-URL: https://bugs.gentoo.org/show_bug.cgi?id=406021
2015-11-11Standardize macro tests for gnu hurdBenda Xu
This also fixes breakage of GNU/hurd builds introduced by commit 3f82edbeb92.
2015-11-05librc: rework overriding rc.conf options from the kclWilliam Hubbs
Rename the rc_conf_override function to describe its purpose better, drop one conditional compile by making it available everywhere, and move the call to it after the optional rc.conf.d directory is processed.
2015-11-05librc: Remove redundant code from rc_config_loadWilliam Hubbs
2015-11-05Add rc.conf.d supportWilliam Hubbs
This makes it possible to override settings in rc.conf by adding a directory @SYSCONFDIR@/rc.conf.d and putting files in this directory. The files will be processed in lexical order, and the last setting in these files will be used.
2015-05-04librc: Fix crash if the service name is the same as the including runlevelJakob Drexel
If a service has the same name as the runlevel it is in, openrc will crash on changing to such runlevel. It goes in a recursive madness and eventually gets a SEGV while in snprintf (don't know why). This fixes two errors: 1. ls_dir stats files not with full path -> stat always returns != 0 2. ls_dir adds files to list if stat failed This fixes #53.

We are bundling this to allow building on musl-based systems since musl does not include <sys/queue.h>.
2014-10-23Fix all tests for GNU/kFreeBSDWilliam Hubbs
It is necessary to check for both the kernel and c library because __FreeBSD_kernel is also defined on native FreeBSD [1]. [1] http://sourceforge.net/p/predef/wiki/OperatingSystems/

2014-10-22Fix GNU/kFreeBSD portSvante Signell
Check for __FreeBSD_kernel instead of __GLIBC__ in source files. note from William Hubbs: I was told this is a better check for GNU/kFreeBSD than checking the C library the source is being compiled against. GNU/kFreeBSD than checking which library we are using.
