  "message": "security: make inode_follow_link RCU-walk aware\n\ninode_follow_link now takes an inode and rcu flag as well as the\ndentry.\n\ninode is used in preference to d_backing_inode(dentry), particularly\nin RCU-walk mode.\n\nselinux_inode_follow_link() gets dentry_has_perm() and\ninode_has_perm() open-coded into it so that it can call\navc_has_perm_flags() in way that is safe if LOOKUP_RCU is set.\n\nCalling avc_has_perm_flags() with rcu_read_lock() held means\nthat when avc_has_perm_noaudit calls avc_compute_av(), the attempt\nto rcu_read_unlock() before calling security_compute_av() will not\nactually drop the RCU read-lock.\n\nHowever as security_compute_av() is completely in a read_lock()ed\nregion, it should be safe with the RCU read-lock held.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n",
