(This is analogous to the rc_stringlist change.)
This gives a hint to the compiler that allocations (return values)
from this function should be paired with a corresponding dealloc/free
function.

This gives a hint to the compiler that allocations (return values)
from this function should be paired with a corresponding dealloc/free
function
In this case, it means that every rc_stringlist that rc_stringlist_new()
returns should eventually be freed by calling rc_stringlist_free(ptr)
where ptr is the relevant rc_stringlist.
We have to add a test for this into the build system
because only GCC supports this for now. In future, we might
be able to use meson's has_function_attribute (it does support
'malloc', just not AFAICT 'malloc with arguments').

Both 'pkg' and 'local' are referenced within list,
so we can't free them yet.

'services' is still referenced by the list
which gets returned. We can't free it.
Thanks to GCC 11's -fanalyzer.

This fixes #516.

- drop initialization of some variables.
- use eerrorx where possible
- drop final cleanup instructions
|
|
There have been a number of subtle improvements and cleanups to seedrng,
including using openat and locking the directory fd instead of a
separate lock file. Also various stylistic cleanups.
This fixes #519.

- drop old build system
- move shared include and source files to common directory
- drop "rc-" prefix from shared include and source files
- move executable-specific code to individual directories under src
- adjust top-level .gitignore file for new build system
This closes #489.

Now that we have the command line arguments, there's no need for the
environment variables.

This cleans up the exit path a little bit.

The RNG can't actually be seeded from a shell script, due to the
reliance on ioctls. For this reason, the seedrng project provides a
basic script meant to be copy and pasted into projects like OpenRC and
tweaked as needed: https://git.zx2c4.com/seedrng/about/
This commit imports it into OpenRC and wires up /etc/init.d/urandom to
call it. It shouldn't be called by other things on the system, so it
lives in rc_sbindir.
Closes #506.
Closes #507.

This should make the code easier to maintain without having to remember
what the exact 0x100 constant means.
|
|
We use 0x100+ to avoid collisions in the 8 bit getopt interface, so
switch 0x80 to align with the other existing 0x100 options we have.

This add No New Privs flag for start-stop-daemon and supervise-daemon
by adding --no-new-privs flag. As a result, the user set the No New
Privs flag for the program should run with.

This adds securebits flags for start-stop-daemon and supervise-daemon
by adding --secbits option. As a result, the user can specify
securebits the program should run with. see capabilities(7)

This is a partial revert of commit 8e02406d ("rc-misc.c: remove
references to PATH_MAX"), which changed 'file' to a null pointer with no
associated storage.

This adds capabilities for start-stop-daemon by adding --capabilities
option. As a result, the user can specify the inheritable, ambient and
bounding set by define capabilities in the service script.
This fixes #314.

This commit adds a new --oom-score-adj option to start-stop-daemon and
supervise-daemon, as well as an equivalent SSD_OOM_SCORE_ADJ environment
variable. If either of these are specified (with the command-line
option taking precedence), then the specified adjustment value is
written to /proc/self/oom_score_adj after forking but prior to exec'ing
the daemon (at the time when nice and ionice are applied).
Additionally, per a suggestion by Mike Frysinger, the suggested values
for the SSD_NICELEVEL, SSD_IONICELEVEL, and SSD_OOM_SCORE_ADJ variables
in the example config file are now given as zeros, which are the
kernel's default values of these process knobs for the init process at
boot. Note that uncommenting any of these zero-valued suggestions will
cause SSD/SD to set the corresponding process knob affirmatively to
zero, whereas leaving the variable unset (and the equivalent command-
line option unspecified) means SSD/SD will not change the corresponding
process knob from its inherited value.
See: https://github.com/OpenRC/openrc/pull/435#discussion_r688310672
This fixes #435.

Newer gcc reports:
broadcast.c: In function 'broadcast':
broadcast.c:132:15: warning: variable 'tp' might be clobbered by 'longjmp' or 'vfork' [-Wclobbered]
132 | FILE *tp;
Move the storage off the stack to avoid. This makes the function
not safe for multithread use, but we don't do that anywhere, so
who cares!

This makes the URIs shorter and dynamic: whatever the default branch
the repo uses will be used.

The existing copyright notices in the file headers cover these vars.

Make this a const pointer to the storage directly instead of a pointer
variable that points to the storage. Makes the code slightly smaller.

Pam generates pkgconfig files now, so meson can use them to find the pam
