2022-05-08librc: mark rc_deptree_* functions as mallocsSam James
(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. Signed-off-by: Sam James <sam@gentoo.org>

2022-05-08librc: mark stringlist functions as mallocsSam James
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'). Signed-off-by: Sam James <sam@gentoo.org>
2022-05-08librc: fix potential use-after-freeSam James
Both 'pkg' and 'local' are referenced within list, so we can't free them yet. Signed-off-by: Sam James <sam@gentoo.org>

2022-04-30multiple spelling and typo fixesJosh Soref
This fixes #516.
2022-04-20seedrng: initialize seed_dirWilliam Hubbs
2022-04-20seedrng: more improvementsWilliam Hubbs
- drop initialization of some variables. - use eerrorx where possible - drop final cleanup instructions
2022-04-20seedrng: incorporate various improvementsJason A. Donenfeld
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2022-04-09openrc-shutdown: remove rc- prefix from file namesWilliam Hubbs
2022-04-07start-stop-daemon: remove rc-prefix from file namesWilliam Hubbs
2022-04-06migrate fully to meson build systemWilliam Hubbs
- 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.
2022-03-30seedrng: remove environment variablesJason A. Donenfeld
Now that we have the command line arguments, there's no need for the environment variables. This fixes #511.
2022-03-30seedrng.c: multiple cleanupsWilliam Hubbs
This fixes #508.
2022-03-29seedrng: clean up fds and avoid -1 close on exit (#509)Jason A. Donenfeld
This cleans up the exit path a little bit. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2022-03-26Use seedrng for seeding the random number generatorJason A. Donenfeld
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2022-03-05Add Posix Scheduling Support to start-stop-daemon (#497)sad-goldfish
2022-03-05switch 0x100 constants to enumsMike Frysinger
This should make the code easier to maintain without having to remember what the exact 0x100 constant means.
2022-03-05switch 0x80 to 0x103 for long optionsMike Frysinger
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.
2022-02-06linux: Add support for No New Privs flagLinkTed
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. see PR_SET_NO_NEW_PRIVS prctl(2)
2022-02-06capabilities: Add support for securebits flagsLinkTed
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)
2022-01-26rc-misc.c: Allocate memory for 'file'Matt Turner
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. ../openrc-0.44.10/src/rc/rc-misc.c: In function ‘_rc_deptree_load’: ../openrc-0.44.10/src/rc/rc-misc.c:392:33: warning: ‘%s’ directive argument is null [-Wformat-overflow=] 392 | eerror("Clock skew detected with `%s'", file); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fixes: 8e02406d ("rc-misc.c: remove references to PATH_MAX") Closes: #493

2021-12-23capabilities: Add support for Linux capabilities(7)LinkTed
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.
2021-12-22add option for OOM score adjustmentMatt Whitlock
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.
2021-12-21start-stop-daemon: fix typo in error messageMatt Whitlock
2021-12-21broadcast: fix compiler warningsMike Frysinger
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!
2021-12-21code style: remove space after unary "not" operatorMatt Whitlock
There are no semantic changes in this commit. Suggested-by: Mike Frysinger <vapier@gentoo.org> See: https://github.com/OpenRC/openrc/pull/435#pullrequestreview-727035394
2021-12-20use HEAD in git URIs to point to the default branchMike Frysinger
This makes the URIs shorter and dynamic: whatever the default branch the repo uses will be used.
2021-12-20drop unused copyright variablesMike Frysinger
The existing copyright notices in the file headers cover these vars.
2021-12-20change getopt definition to elide pointer storageMike Frysinger
Make this a const pointer to the storage directly instead of a pointer variable that points to the storage. Makes the code slightly smaller.
