- We now kill the program on violations like OpenBSD
- We now print a message explaining which promise is needed
- This change also fixes a linkage bug with thread local storage
- Your sigaction() handlers should now be more thread safe
A new `__pledge_mode` global has been introduced to make pledge() more
customizable on Linux. For example:
__attribute__((__constructor__)) static void init(void) {
__pledge_mode = SECCOMP_RET_ERRNO | EPERM;
}
Can be used to restore our old permissive pledge() behavior.
