Merge branch 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security system updates from James Morris: - incorporate new socketpair() hook into LSM and wire up the SELinux and Smack modules. From David Herrmann: "The idea is to allow SO_PEERSEC to be called on AF_UNIX sockets created via socketpair(2), and return the same information as if you emulated socketpair(2) via a temporary listener socket. Right now SO_PEERSEC will return the unlabeled credentials for a socketpair, rather than the actual credentials of the creating process." - remove the unused security_settime LSM hook (Sargun Dhillon). - remove some stack allocated arrays from the keys code (Tycho Andersen) * 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: dh key: get rid of stack allocated array for zeroes dh key: get rid of stack allocated array big key: get rid of stack array allocation smack: provide socketpair callback selinux: provide socketpair callback net: hook socketpair() into LSM security: add hook for socketpair() security: remove security_settime
