9.87 failure_policy ¶

#define OOM_ALLOW_PROC_KILL 1

struct fail_modes {
    uint64_t placeholder;
};

int failure_policy(struct fail_modes *old, struct fail_modes *new);

This syscall fetches and customized kernel behaviour on a series of failure conditions. old, if not null, can be used for fetching the values used at the time of calling, while new, if not null, will be used to set new values.

The values contained by the arguments are ignored, these values are reserved for future error recovery configuration not implemented right now.

This syscall returns 0 on success or -1 on failure, with the errno:

EFAULT

The passed buffers were pointing to invalid memory.

EACCES

When setting new values with new, the calling process did not have the capability MAC_CAP_SYSMAC.
