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.

2021-12-21broadcast: 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!

2021-12-20change 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.

Since musl 1.2 time_t is a 64 bit value, even on 32 bit systems. A hotfix for printing the value is simply using PRIu64 from inttypes.h in the format string. This fixes #446.

2021-08-17supervise-daemon: implement SSD_IONICELEVELMatt Whitlock
supervise-daemon was apparently overlooked when support for the SSD_IONICELEVEL environment variable was added. This commit brings supervise-daemon up to parity with start-stop-daemon with respect to this environment variable.

The previous fix excludes PIDs of processes running in a different namespace regardless of whether the PID has been explicitly stored in a PID file mentioned in the --pidfile parameter.

2020-11-27src/rc/checkpath.c: replace mkdir() with mkdirat().Michael Orlitzky
The do_check() function recently gained some defenses against symlink replacement attacks that involve the use of *at functions in place of their vanilla counterparts; openat() instead of open(), for example. One opportunity to replace mkdir() with mkdirat() was missed, however, and this commit replaces it. This fixes #386.

2020-11-27start-stop-daemon, supervise-daemon: fix parsing of usernames passed via ↵Johannes Heimansberg
--user that start with a number start-stop-daemon and supervise-daemon parse usernames and group names passed via the --user argument as numeric UID/GID if they start with a number (e.g. user "4foo" will be treated as UID 4). This results in the process that is being started to run under a totally unexpected user if that UID exists. Even though the result of the sscanf calls are tested for a result of exactly 1, which means exactly one value was extracted, because sscanf's format string only contains only one placeholder, it will never return a value greater than 1, even if there are still characters left to be parsed. This causes start-stop-daemon and supervise-daemon to assume that usernames starting with a number are just that number. Adding a second placeholder "%1s" to the format string, which matches a string of length 1, makes sure that sscanf can distinguish between pure numbers (in which case it will return 1) and strings either starting with a number (in which case it will return 2) and any other string (in which case it will return 0). This fixes #379. This fixes #380.
2020-11-20start-stop-daemon: Don't segfault if --exec was given a non-existing file nameLars Wendler

2020-11-20checkpath: fix CVE-2018-21269William Hubbs
This walks the directory path to the file we are going to manipulate to make sure that when we create the file and change the ownership and permissions we are working on the same file. Also, all non-terminal symbolic links must be owned by root. This will keep a non-root user from making a symbolic link as described in the bug. If root creates the symbolic link, it is assumed to be trusted. On non-linux platforms, we no longer follow non-terminal symbolic links by default. If you need to do that, add the -s option on the checkpath command line, but keep in mind that this is not secure. This fixes #201.
