2019-07-24Fix build with ClangMartin Wilke
This fixes #313.
2019-02-26remove hidden-visibility.hWilliam Hubbs
I am removing this on the advice of a member of the Gentoo toolchain team. It was explained to me that this doesn't offer any significant benefits to OpenRC. If anyone ffeels differently, please open a pull request reverting this and adding an explanation of what it does and how to know which functions to mark hidden in the future. This fixes #301.

2019-02-23Revert "src/librc/librc-daemon.c: fix buffer overrun in pid_is_argv"William Hubbs
This reverts commit 084877eb52971faf8f52c780ddd08ed9af140eb6. The mentioned commit caused some systems to have some services reported as crashed. This fixes #297. This fixes #298.
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.

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.

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.

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.

2014-06-20librc: filter out container processes on OpenVZ hostWilliam Hubbs
Thanks to info and testing done by Daniel Robbins <drobbins@funtoo.org>, there is now a fix for this. Below is his description of the steps OpenRC needed to use. 1) See if /proc/<pid>/status exists 2) If it does, see if it has a "envID:" field 3) If it does, see if "envID:" is set to "0" 4) If so, then it's one of the host's processes and should be a candidate for the list. Otherwise, it is one of the container's processes and should be ignored. This should fix the bug and allow start-stop-daemon to work properly on OpenVZ hosts.
