On gcc-10 (and gcc-9 -fno-common) build fails as:

gcc-10 will change the default from -fcommon to fno-common:
https://gcc.gnu.org/PR85678.
The error also happens if CFLAGS=-fno-common passed explicitly.
This fixes #348.

When executable is provided just by name (and therefore searched in a
path), exec_file is reset to NULL every time. exists() handles it being
NULL just fine, but dereferencing it in eerror does not work.
Fixes #326
Fixes #327

This allows openrc to direct sysvinit to shut down the system by setting
the INIT_HALT environment variable appropriately. Also, we do not try to
communicate with sysvinit if its fifo does not exist.

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.

The do_openrc() function was not waiting properly for the child process
which started the runlevel to return. We need to repeatedly call
waitpid() until its return value matches the pid of the child process or
the child process does not exist.
This fixes #216.
This fixes #300.

This reverts commit 084877eb52971faf8f52c780ddd08ed9af140eb6.
The mentioned commit caused some systems to have some services reported
as crashed.

In some cases deptree or depinfo can be NULL, check
before dereferencing.

The 'readelf'-based tests cover a few situations:
1. undefined symbols in shared libraries
2. unexpected exports in shared libraries
Bug #575958 shows that [2.] implementation is too simplistic
in assuming that presence of relocation equals to export presence.
It is incorrect for PLT stubs and local symbols.
Let's just drop these tests.
If one needs to cover [1.] it is better to use LDFLAGS=-Wl,--no-undefined.
This closes #292.

The -f option can be used when showing the status of services in
runlevels to allow making the output more easily parsable.
Currently, the .ini format is the only one supported.

Clean up code indented with mixed tabs and spaces.
No actual code changes.
This fixes #280.

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.

These are not standard.
For more information see issue #279.
This fixes #279.

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.

The following will cause a segfault due to NULL being
passed to strcmp(3)
$ RC_SVCNAME=foo supervise-daemon
Fix the bounds check on argc in main. If argc<=1, then
it is not safe to dereference argv[1].

The statement
ll = strlen(applet);
appears twice in the same block without any
intervening assignment to the variables
'll' or 'applet'
Remove the second (duplicate) statement.

In order to run healthcheck() and the unhealthy() function, add an
exec_command call to the supervisor.
Another difference is This function also logs errors instead of
attempting to display them.
This is for #271.
|

This will make it easier to track down why the supervisor intermittently
hangs after it runs for a long time.

Since the pid file is internal to us, start moving toward deprecating it
by not requiring the user to specify it.
In the next release, I plan on working on code to start phasing out the
use of a pid file if this is possible.

This will allow us to signal the daemon we are supervising as well as
send other commands to the supervisor in the future.
This fixes #227.
|
|
This is needed in preparation for adding support for a fifo to allow us
to communicate with the supervisor to ask it to signal the child it is
supervising.

This reverts commit 2af0cedd5952d7da71681b7a636dff3540e4295d.
After speaking with Luis Ressel on the Gentoo selinux team, I am reverting
this commit for the following reasons:
- Luis told me that he feels this is not the solution we need to address
the concern with checkpath; I will be working with him on another
solution.
- There are concerns about the way the path variable was handled
and the assert() call.
The path variable should be dynamically allocated using xasprintf
instead of defining a length at compile time. This would eliminate the
need for the assert() call.
- It introduces the definition of _GNU_SOURCE which makes it
easier to introduce portability concerns in the future (see #262).
|
|
This avoids opening directories/files with read permission, which is
sometimes rejected by selinux policy.
