      "message": "cpufreq: cpu-boost: Resolve deadlock when waking up sync thread\n\nCPU boost driver receives notification from scheduler when threads\nmigrate towards a cpu and in turn wakes up a sync thread associated\nwith that cpu to handle any required frequency transitions. The wakeup\ncall however can lead to a deadlock inside scheduler under some\ncircumstance. The deadlock is seen when sync thread is the only thread\nrunning on a cpu and goes to sleep (say by calling wait_event() -\u003e\nschedule()). Midway through this sleep (schedule()) call, while cpu is\nstill running in context of sync thread, scheduler attempts a load\nbalance (realizing that cpu is about to become idle) which can result\nin tasks being migrated towards the cpu going idle. This will cause\nmigration notification to be issued and in turn a wakeup on sync\nthread. The wakeup call however gets stuck in below while() loop\ninside scheduler:\n\ntry_to_wake_up(struct task_struct *p, ...)\n{\n\n        /*\n         * If the owning (remote) cpu is still in the middle of\n\t * schedule() with this task as prev, wait until its done\n\t * referencing the task.\n         */\n\twhile (p-\u003eon_cpu)\n\t\tcpu_relax();\n\n}\n\nA possible fix could be to teach try_to_wake_up() about this\nspecial case.

We need to get the siginfo for each signal on\ncheckpointing dump, and then return it back on restore.\n\nThe first problem is that the kernel doesn\u0027t report complete siginfos to\nuserspace.  In a signal handler the kernel strips SI_CODE from siginfo.\nWhen a siginfo is received from signalfd, it has a different format with\nfixed sizes of fields.  The interface of signalfd was extended.  If a\nsignalfd is created with the flag SFD_RAW, it returns siginfo in a raw\nformat.\n\nrt_sigqueueinfo looks suitable for restoring signals, but it can\u0027t send\nsiginfo with a positive si_code, because these codes are reserved for\nthe kernel.  In the real world each person has right to do anything with\nhimself, so I think a process should able to send any siginfo to itself.\n\nThis patch:\n\nThe kernel prevents sending of siginfo with positive si_code, because\nthese codes are reserved for kernel.  I think we can allow a task to\nsend such a siginfo to itself.  This operation should not be dangerous.\n\nThis functionality is required for restoring signals in\ncheckpoint/restart.\n\nChange-Id: I40101d87eeb53ae05cfa0949439577a8f3f58f94\nSigned-off-by: Andrey Vagin \u003cavagin@openvz.org\u003e\nCc: Serge Hallyn \u003cserge.hallyn@canonical.com\u003e\nCc: \"Eric W.

      "message": "selinux: Android kernel compatibility with M userspace\n\nNOT intended for new Android devices - this commit is unnecessary\nfor a target device that does not have a previous M variant.\n\nDO NOT upstream. Android only.\n\nMotivation:\n\nThis commit mitigates a mismatch between selinux kernel and\nselinux userspace. The selinux ioctl white-listing binary policy\nformat that was accepted into Android M differs slightly from what\nwas later accepted into the upstream kernel. This leaves Android\nmaster branch kernels incompatible with Android M releases. This\npatch restores backwards compatibility. This is important because:\n\n1. kernels may be updated on a different cycle than the rest of the\n   OS e.g. security patching.\n2. Android M bringup may still be ongoing for some devices. The\n   same kernel should work for both M and master.\n\nBackwards compatibility is achieved by checking for an Android M\npolicy characteristic during initial policy read and converting to\nupstream policy format. The inverse conversion is done for policy\nwrite as required for CTS testing.\n\nBug: 22846070\nChange-Id: I2f1ee2eee402f37cf3c9df9f9e03c1b9ddec1929\nSigned-off-by: Jeff Vander Stoep \u003cjeffv@google.com\u003e\n"

      "message": "selinux: extended permissions for ioctls\n\n(cherry picked from commit fa1aa143ac4a682c7f5fd52a3cf05f5a6fe44a0a)\n\nAdd extended permissions logic to selinux. Extended permissions\nprovides additional permissions in 256 bit increments. Extend the\ngeneric ioctl permission check to use the extended permissions for\nper-command filtering. Source/target/class sets including the ioctl\npermission may additionally include a set of commands. Example:\n\nallowxperm \u003csource\u003e \u003ctarget\u003e:\u003cclass\u003e ioctl unpriv_app_socket_cmds\nauditallowxperm \u003csource\u003e \u003ctarget\u003e:\u003cclass\u003e ioctl priv_gpu_cmds\n\nWhere unpriv_app_socket_cmds and priv_gpu_cmds are macros\nrepresenting commonly granted sets of ioctl commands.\n\nWhen ioctl commands are omitted only the permissions are checked.\nThis feature is intended to provide finer granularity for the ioctl\npermission that may be too imprecise. For example, the same driver\nmay use ioctls to provide important and benign functionality such as\ndriver version or socket type as well as dangerous capabilities such\nas debugging features, read/write/execute to physical memory or\naccess to sensitive data. Per-command filtering provides a mechanism\nto reduce the attack surface of the kernel, and limit applications\nto the subset of commands required.\n\nThe format of the policy binary has been modified to include ioctl\ncommands, and the policy version number has been incremented to\nPOLICYDB_VERSION_XPERMS_IOCTL\u003d30 to account for the format\nchange.\n\nThe extended permissions logic is deliberately generic to allow\ncomponents to be reused e.g. netlink filters\n\nSigned-off-by: Jeff Vander Stoep \u003cjeffv@google.com\u003e\nAcked-by: Nick Kralevich \u003cnnk@google.com\u003e\nSigned-off-by: Paul Moore \u003cpmoore@redhat.com\u003e\nBug: 22846070\nChange-Id: I299dc776d2f98d593ecc051707110c92a085350f\n"
