The master branch has been updated. Changelog to v22: * Return -EIO instead of -ECANCELED when ptrace() fails to read a TCS page. * In the reclaimer, pin the page before ENCLS[EBLOCK] because pinning can fail (because of OOM) even in legit behaviour and after EBLOCK the reclaiming flow can be only reverted by killing the whole enclave. /Jarkko
