From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The task of working out which flavor of qemu to use gets more complex
as more types of CPUs are supported. Adding Power makes three in addition
to 32-bit and 64-bit x86, so it is time to pull this out into a function.
This commit therefore creates an identify_qemu function and also adds
a --qemu-cmd command-line argument for the inevitable case where the
identify_qemu cannot figure it out.

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The TREE_RCU test cases were first put in place many years ago, and have
been incrementally modified rather than being reworked. This commit
therefore completes a long-overdue reworking of the TREE_RCU test cases.

+This document gives a brief rationale for the TREE_RCU-related test
+cases, a group that includes TREE_PREEMPT_RCU.
+
+
+Kconfig Parameters:
+
+CONFIG_DEBUG_LOCK_ALLOC -- Do three, covering CONFIG_PROVE_LOCKING & not.
+CONFIG_DEBUG_OBJECTS_RCU_HEAD -- Do one.
+CONFIG_HOTPLUG_CPU -- Do half. (Every second.)
+CONFIG_HZ_PERIODIC -- Do one.
+CONFIG_NO_HZ_IDLE -- Do those not otherwise specified. (Groups of two.)
+CONFIG_NO_HZ_FULL -- Do two, one with CONFIG_NO_HZ_FULL_SYSIDLE.
+CONFIG_NO_HZ_FULL_SYSIDLE -- Do one.
+CONFIG_PREEMPT -- Do half. (First three and #8.)
+CONFIG_PROVE_LOCKING -- Do all but two, covering CONFIG_PROVE_RCU and not.
+CONFIG_PROVE_RCU -- Do all but one under CONFIG_PROVE_LOCKING.
+CONFIG_PROVE_RCU_DELAY -- Do one.
+CONFIG_RCU_BOOST -- one of TREE_PREEMPT_RCU.
+CONFIG_RCU_BOOST_PRIO -- set to 2 for _BOOST testing.
+CONFIG_RCU_CPU_STALL_INFO -- do one with and without _VERBOSE.
+CONFIG_RCU_CPU_STALL_VERBOSE -- do one with and without _INFO.
+CONFIG_RCU_FANOUT -- Cover hierarchy as currently, but overlap with others.
+CONFIG_RCU_FANOUT_EXACT -- Do one.
+CONFIG_RCU_FANOUT_LEAF -- Do one non-default.
+CONFIG_RCU_FAST_NO_HZ -- Do one, but not with CONFIG_RCU_NOCB_CPU_ALL.
+CONFIG_RCU_NOCB_CPU -- Do three, see below.
+CONFIG_RCU_NOCB_CPU_ALL -- Do one.
+CONFIG_RCU_NOCB_CPU_NONE -- Do one.
+CONFIG_RCU_NOCB_CPU_ZERO -- Do one.
+CONFIG_RCU_TRACE -- Do half.
+CONFIG_SMP -- Need one !SMP for TREE_PREEMPT_RCU.
+RCU-bh: Do one with PREEMPT and one with !PREEMPT.
+RCU-sched: Do one with PREEMPT but not BOOST.
+
+
+Hierarchy:
+
+TREE01. CONFIG_NR_CPUS=8, CONFIG_RCU_FANOUT=8, CONFIG_RCU_FANOUT_EXACT=n.
+TREE02. CONFIG_NR_CPUS=8, CONFIG_RCU_FANOUT=3, CONFIG_RCU_FANOUT_EXACT=n,

+CONFIG_NO_HZ_FULL_SYSIDLE_SMALL
+
+ Defer until Frederic uses this.
+
+CONFIG_PREEMPT_COUNT
+CONFIG_PREEMPT_RCU
+
+ Redundant with CONFIG_PREEMPT, ignore.
+
+CONFIG_RCU_BOOST_DELAY
+
+ Inspection suffices, ignore.
+
+CONFIG_RCU_CPU_STALL_TIMEOUT
+
+ Inspection suffices, ignore.
+
+CONFIG_RCU_STALL_COMMON
+
+ Implied by TREE_RCU and TREE_PREEMPT_RCU.
+
+CONFIG_RCU_TORTURE_TEST
+CONFIG_RCU_TORTURE_TEST_RUNNABLE
+
+ Always used in KVM testing.
+
+CONFIG_RCU_USER_QS

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The output of the rcutorture scripts often requires interpretation, so
this commit simplifies this interpretation by tagging messages as
BUGs (colored red) or WARNINGs (colored yellow).

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

As it stands, the default kernel boot parameters generated from
the Kconfig fragment will override any supplied with the .boot
file that can optionally accompany a Kconfig fragment. Rearrange
ordering to permit the specific .boot arguments to override those
generated by analyzing the Kconfig fragment.

From: "Paul E. McKenney"


Hello!

This series contains scripting that I use to test RCU under KVM, including
different Kconfig combinations to test, automated launching and monitoring
of multiple tests scenarios, kernel-version adaptation, and automated
evaluation of test output. This version works on x86 32- and 64-bit,
and limps on PowerPC.

This also contains refactored test scenarios that greatly improve RCU
test coverage (resulting in fixes) while also reducing test run time.
There is a fair amount of work remaining, particularly in the areas of
documentation, automating initrd generation, and general reduction in
user-hostility. Nevertheless, a much-needed improvement in the kernel's
RCU-testing capabilities.

Thanx, Paul

Different Kconfig parameters apply to different kernel versions, as
do different rcutorture module parameters. This commit allows the
rcutorture test scripts to adjust for different kernel versions.

+This document describes one way to create the initrd directory hierarchy
+in order to allow an initrd to be built into your kernel. The trick
+here is to steal the initrd file used on your Linux laptop, Ubuntu in
+this case. There are probably much better ways of doing this.
+
+That said, here are the commands:
+
+------------------------------------------------------------------------
+zcat /initrd.img > /tmp/initrd.img.zcat
+mkdir initrd
+cd initrd
+cpio -id < /tmp/initrd.img.zcat
+------------------------------------------------------------------------
+
+Interestingly enough, if you are running rcutorture, you don't really
+need userspace in many cases. Running without userspace has the
+advantage of allowing you to test your kernel independently of the
+distro in place, the root-filesystem layout, and so on. To make this
+happen, put the following script in the initrd's tree's "/init" file,
+with 0755 mode.
+
+------------------------------------------------------------------------
+#!/bin/sh
+
+[ -d /dev ] || mkdir -m 0755 /dev
+[ -d /root ] || mkdir -m 0700 /root
+[ -d /sys ] || mkdir /sys
+[ -d /proc ] || mkdir /proc
+[ -d /tmp ] || mkdir /tmp
+mkdir -p /var/lock
+mount -t sysfs -o nodev,noexec,nosuid sysfs /sys
+mount -t proc -o nodev,noexec,nosuid proc /proc
+# Some things don't work properly without /etc/mtab.
+ln -sf /proc/mounts /etc/mtab
+

+This document describes one way to created the rcu-test-image file
+that contains the filesystem used by the guest-OS kernel. There are
+probably much better ways of doing this, and this filesystem could no
+doubt be smaller. It is probably also possible to simply download
+an appropriate image from any number of places.
+
+That said, here are the commands:
+
+------------------------------------------------------------------------
+dd if=/dev/zero of=rcu-test-image bs=400M count=1
+mkfs.ext3 ./rcu-test-image
+sudo mount -o loop ./rcu-test-image /mnt
+
+# Replace "precise" below with your favorite Ubuntu release.
+# Empirical evidence says this image will work for 64-bit, but...
+# Note that debootstrap does take a few minutes to run. Or longer.
+sudo debootstrap --verbose --arch i386 precise /mnt http://archive.ubuntu.com/ubuntu
+cat << '___EOF___' | sudo dd of=/mnt/etc/fstab
+# UNCONFIGURED FSTAB FOR BASE SYSTEM

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The v3.12 version of the kernel added the CONFIG_NO_HZ_FULL_SYSIDLE
Kconfig parameter, so this commit adds a version transition at that
point.

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

been incrementally modified rather than being reworked. This commit
therefore completes a long-overdue reworking of the TINY_RCU test cases.

+This document gives a brief rationale for the TINY_RCU test cases.
+
+
+Kconfig Parameters:
+
+CONFIG_DEBUG_LOCK_ALLOC -- Do all three and none of the three.
+CONFIG_PREEMPT_COUNT
+CONFIG_RCU_TRACE
+
+The theory here is that randconfig testing will hit the other six possible
+combinations of these parameters.
+
+
+Kconfig Parameters Ignored:
+
+CONFIG_DEBUG_OBJECTS_RCU_HEAD
+CONFIG_PROVE_RCU
+
+ In common code tested by TREE_RCU test cases.
+
+CONFIG_NO_HZ_FULL_SYSIDLE
+CONFIG_RCU_NOCB_CPU
+CONFIG_RCU_USER_QS
+
+ Meaningless for TINY_RCU.

+CONFIG_RCU_STALL_COMMON

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The TREE08 Kconfig fragment does not enable tracing, which is appropriate
for its test case. However, this can be inconvenient in cases where
TREE08 locates RCU bugs. This commit therefore adds a TREE08-T that
differs from TREE08 only in enabling CONFIG_RCU_TRACE.

This commit adds --buildonly, which does the builds specified by the
--configs argument, but does not boot or test the resulting kernels.

Don't grab the configuration fragment from the configs directory because
it might well have been changed since the test was run. Instead, use
the ConfigFragment file that was placed in the results directory.

This commit adds the --no-initrd argument to kvm.sh, which permits
initrd to be contained in a root partition specified by the --bootargs
argument. Without --no-initrd, the kernel build expects an initrd
directory in the same rcutorture directory that contains bin and configs.

You're right, I totally screwed that up. Part of the problem is that
I should have cleaned up the if statement in commit 6265e169cd31 so
that it looked like this:

r->entropy_total += nbits;
if (!r->initialized && (r->entropy_total > 128)) {
r->initialized = 1;
r->entropy_total = 0;
}
}

... and so at the top of the dev branch, it should have looked like
this:

r->entropy_total += nbits;
if (!r->initialized && (r->entropy_total > 128)) {
if (r == &nonblocking_pool)
pr_notice("random: %s pool is initialized\n", r->name);
r->initialized = 1;
r->entropy_total = 0;
}

Instead, I had a more complicated structure which confused me when I
cleaned up the merge.

So I'm going to propose the following merge resolution:

diff --cc drivers/char/random.c
index cdf4cfb,4fe5609..0000000
--- a/drivers/char/random.c
+++ b/drivers/char/random.c
@@@ -654,14 -601,12 +654,13 @@@ retry
if (cmpxchg(&r->entropy_count, orig, entropy_count) != orig)
goto retry;

- if (!r->initialized && nbits > 0) {
- r->entropy_total += nbits;
- if (r->entropy_total > 128) {
- r->initialized = 1;
- if (r == &nonblocking_pool)
- prandom_reseed_late();
+ r->entropy_total += nbits;
- if (!r->initialized && nbits > 0) {
- if (r->entropy_total > 128) {
- if (r == &nonblocking_pool)
- pr_notice("random: %s pool is initialized\n",
- r->name);
- r->initialized = 1;
- r->entropy_total = 0;
++ if (!r->initialized && (r->entropy_total > 128)) {
++ r->initialized = 1;
++ r->entropy_total = 0;
++ if (r == &nonblocking_pool) {
++ prandom_reseed_late();
++ pr_notice("random: %s pool is initialized\n", r->name);
}
}

It does fold a cleanup in with the merge resolution, but it's not
actually changing anything in terms of code behavior, and it makes the
resulting merge much more obvious.

Are you OK with that?

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The sparse checking for rcu_assign_pointer() was recently upgraded
to reject non-__kernel address spaces. This also rejects __rcu,
which is almost always the right thing to do. However, the uses in
sta_info_hash_del() are legitimate: They are assigning a pointer to an
element from an RCU-protected list, and all elements of this list are
already visible to caller.

This commit therefore silences this false positive by laundering the
pointer using ACCESS_ONCE() as suggested by Eric Dumazet and Josh
Triplett.

Triplett, or by using RCU_INIT_POINTER() for NULL pointer assignments.

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The sparse checking for rcu_assign_pointer() was recently upgraded
to reject non-__kernel address spaces. This also rejects __rcu,
which is almost always the right thing to do. However, the use in
ip6_tnl_unlink() is legitimate: It is assigning a pointer to an element
from an RCU-protected list, and all elements of this list are already
visible to caller.

This commit therefore silences this false positive by laundering the
pointer using ACCESS_ONCE() as suggested by Eric Dumazet and Josh
Triplett.
