Subject: [GIT PULL] Security subsystem changes for 4.3
Highlights:
o PKCS#7 support added to support signed kexec, also utilized for module
signing. See comments in 3f1e1bea.
** NOTE: this requires linking against the OpenSSL library, which must
be installed, e.g. the openssl-devel on Fedora **
o Smack: add IPv6 host labeling; ignore labels on kernel threads;
support smack labeling mounts which use binary mount data
o SELinux: add ioctl whitelisting (see
http://kernsec.org/files/lss2015/vanderstoep.pdf); fix mprotect
PROT_EXEC regression caused by mm change
o Seccomp: add ptrace options for suspend/resume
Please pull.
