[PATCH 04/12] efi: Enable secure boot lockdown automatically when enabled in firmware

The firmware has a set of flags that indicate whether secure boot is enabled and enforcing. Use them to indicate whether the kernel should lock itself down. We also indicate the machine is in secure boot mode by adding the EFI_SECURE_BOOT bit for use with efi_enabled. Signed-off-by: Matthew Garre

[PATCH tip/core/rcu 0/15] v3 RCU idle/no-CB changes for 3.10

Hello! This series contains changes to RCU_FAST_NO_HZ idle entry/exit and also removes restrictions on no-CBs CPUs. 1. Remove restrictions on no-CBs CPUs. 2. Allow some control of no-CBs CPUs at kernel-build time. The option of most interest is probably the one that makes -all-

[PATCH tip/core/rcu 10/15] rcu: Rearrange locking in rcu_start_gp()

From: "Paul E. McKenney" If CPUs are to give prior notice of needed grace periods, it will be necessary to invoke rcu_start_gp() without dropping the root rcu_node structure's ->lock. This commit takes a first step in this direction by moving the release of this lock to the end of rcu_start_gp()

[PATCH tip/core/rcu 14/15] rcu: Abstract rcu_start_future_gp() from rcu_nocb_wait_gp()

From: "Paul E. McKenney" CPUs going idle will need to record the need for a future grace period, but won't actually need to block waiting on it. This commit therefore splits rcu_start_future_gp(), which does the recording, from rcu_nocb_wait_gp(), which now invokes rcu_start_future_gp() to do th

[PATCH tip/core/rcu 13/15] rcu: Rename n_nocb_gp_requests to need_future_gp

From: "Paul E. McKenney" CPUs going idle need to be able to indicate their need for future grace periods. A mechanism for doing this already exists for no-callbacks CPUs, so the idea is to re-use that mechanism. This commit therefore moves the ->n_nocb_gp_requests field of the rcu_node structur

[PATCH tip/core/rcu 11/15] rcu: Repurpose no-CBs event tracing to future-GP events

From: "Paul E. McKenney" Dyntick-idle CPUs need to be able to pre-announce their need for grace periods. This can be done using something similar to the mechanism used by no-CB CPUs to announce their need for grace periods. This commit moves in this direction by renaming the no-CBs grace-period

[PATCH tip/core/rcu 08/15] rcu: Accelerate RCU callbacks at grace-period end

From: "Paul E. McKenney" Now that callback acceleration is idempotent, it is safe to accelerate callbacks during grace-period cleanup on any CPUs that the kthread happens to be running on. This commit therefore propagates the completion of the grace period to the per-CPU data structures, and als

kexec can easily be used to modify the security policy of a running kernel. CONFIG_KEXEC_JUMP makes it trivial for an attacker to simply jump to another kernel, modify the security policy of the previous kernel and then switch back, but it's still merely a matter of difficulty. Long term we'll want

[PATCH tip/core/rcu 15/15] rcu: Make rcu_accelerate_cbs() note need for future grace periods

From: "Paul E. McKenney" Now that rcu_start_future_gp() has been abstracted from rcu_nocb_wait_gp(), rcu_accelerate_cbs() can invoke rcu_start_future_gp() so as to register the need for any future grace periods needed by a CPU about to enter dyntick-idle mode. This commit makes this change. Note

From: "Paul E. McKenney" If CPUs are to give prior notice of needed grace periods, it will be necessary to invoke rcu_start_gp() without dropping the root rcu_node structure's ->lock. This commit takes a second step in this direction by moving the release of this lock to rcu_start_gp()'s callers

[PATCH tip/core/rcu 03/15] rcu: Introduce proper blocking to no-CBs kthreads GP waits

From: "Paul E. McKenney" Currently, the no-CBs kthreads do repeated timed waits for grace periods to elapse. This is crude and energy inefficient, so this commit allows no-CBs kthreads to specify exactly which grace period they are waiting for and also allows them to block for the entire duratio

[PATCH tip/core/rcu 07/15] rcu: Export RCU_FAST_NO_HZ parameters to sysfs

[PATCH tip/core/rcu 09/15] rcu: Make RCU_FAST_NO_HZ take advantage of numbered callbacks

From: "Paul E. McKenney" Because RCU callbacks are now associated with the number of the grace period that they must wait for, CPUs can now take advance callbacks corresponding to grace periods that ended while a given CPU was in dyntick-idle mode. This eliminates the need to try forcing the RCU

[PATCH tip/core/rcu 01/15] rcu: Remove restrictions on no-CBs CPUs

From: "Paul E. McKenney" Currently, CPU 0 is constrained to not be a no-CBs CPU, and furthermore at least one no-CBs CPU must remain online at any given time. These restrictions are problematic in some situations, such as cases where all CPUs must run a real-time workload that needs to be insula

[PATCH tip/core/rcu 02/15] rcu: Provide compile-time control for no-CBs CPUs

From: "Paul E. McKenney" Currently, the only way to specify no-CBs CPUs is via the rcu_nocbs kernel command-line parameter. This is inconvenient in some cases, particularly for randconfig testing, so this commit adds a new set of kernel configuration parameters. CONFIG_RCU_NOCB_CPU_NONE (the de

From: "Paul E. McKenney" Currently, the per-no-CBs-CPU kthreads are named "rcuo" followed by the CPU number, for example, "rcuo". This is problematic given that there are either two or three RCU flavors, each of which gets a per-CPU kthread with exactly the same name. This commit therefore intr
