/** * DOC: erratum_2 * * Erratum 2: Scoped signal handling * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * * This fix addresses an issue where signal scoping was overly restrictive, * preventing sandboxed threads from signaling other threads within the same * process if they belonged to different domains. Because threads are not * security boundaries, user space might assume that any thread within the same * process can send signals between themselves (see :manpage:`nptl(7)` and * :manpage:`libpsx(3)`). Consistent with :manpage:`ptrace(2)` behavior, direct * interaction between threads of the same process should always be allowed. * This change ensures that any thread is allowed to send signals to any other * thread within the same process, regardless of their domain.
