Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next
Conflicts:
net/netfilter/nf_log.c
The conflict in nf_log.c is that in 'net' we added CONFIG_PROC_FS
protection around foo_proc_entry() calls to fix a build failure,
whereas in Pablo's tree a guard if() test around a call is
remove_proc_entry() was removed. Trivially resolved.
Pablo Neira Ayuso says:
====================
The following patchset contains the first batch of
Netfilter/IPVS updates for your net-next tree, they are:
* Three patches with improvements and code refactorization
for nfnetlink_queue, from Florian Westphal.
* FTP helper now parses replies without brackets, as RFC1123
recommends, from Jeff Mahoney.
* Rise a warning to tell everyone about ULOG deprecation,
NFLOG has been already in the kernel tree for long time
and supersedes the old logging over netlink stub, from
myself.
* Don't panic if we fail to load netfilter core framework,
just bail out instead, from myself.
* Add cond_resched_rcu, used by IPVS to allow rescheduling
while walking over big hashtables, from Simon Horman.
* Change type of IPVS sysctl_sync_qlen_max sysctl to avoid
possible overflow, from Zhang Yanfei.
* Use strlcpy instead of strncpy to skip zeroing of already
initialized area to write the extension names in ebtables,
from Chen Gang.
* Use already existing per-cpu notrack object from xt_CT,
from Eric Dumazet.
* Save explicit socket lookup in xt_socket now that we have
early demux, also from Eric Dumazet.

+Marvell Orion/Discovery ethernet controller
+=============================================
+
+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers. As Kirkwood has some issues with proper initialization after reset,
+an extra compatible string is added for it.
+
+* Ethernet controller node
+
+Required controller properties:
+ - #address-cells: shall be 1.
+ - #size-cells: shall be 0.
+ - compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
+ - reg: address and length of the controller registers.
+
+Optional controller properties:
+ - clocks: phandle reference to the controller clock.
+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
+
+* Ethernet port node
+
+Required port properties:
+ - device_type: shall be "network".
+ - compatible: shall be one of "marvell,orion-eth-port",
+ "marvell,kirkwood-eth-port".
+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
+ - interrupts: port interrupt.
+ - local-mac-address: 6 bytes MAC address.
+
+Optional port properties:
+ - marvell,tx-queue-size: size of the transmit ring buffer.
+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
+ - marvell,rx-queue-size: size of the receive ring buffer.
+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
+
+and
+
+ - phy-handle: phandle reference to ethernet PHY.
+
+or
+
+ - speed: port speed if no PHY connected.
+ - duplex: port mode if no PHY connected.
+
+* Node example:
+
+mdio-bus {
+ ...
+ ethphy: ethernet-phy@8 {
+ device_type = "ethernet-phy";
+ ...
+ };
+};
+

+KTHREADS
+
+Name: ehca_comp/%u
+Purpose: Periodically process Infiniband-related work.
+To reduce its OS jitter, do any of the following:
+1. Don't use eHCA Infiniband hardware, instead choosing hardware
+ that does not require per-CPU kthreads. This will prevent these
+ kthreads from being created in the first place. (This will
+ work for most people, as this hardware, though important, is
+ relatively old and is produced in relatively low unit volumes.)
+2. Do all eHCA-Infiniband-related work on other CPUs, including
+ interrupts.
+3. Rework the eHCA driver so that its per-CPU kthreads are
+ provisioned only on selected CPUs.
+
+
+Name: irq/%d-%s
+Purpose: Handle threaded interrupts.
+To reduce its OS jitter, do the following:
+1. Use irq affinity to force the irq threads to execute on
+ some other CPU.
+
+Name: kcmtpd_ctr_%d
+Purpose: Handle Bluetooth work.
+To reduce its OS jitter, do one of the following:
+1. Don't use Bluetooth, in which case these kthreads won't be
+ created in the first place.
+2. Use irq affinity to force Bluetooth-related interrupts to
+ occur on some other CPU and furthermore initiate all
+ Bluetooth activity on some other CPU.
+
+Name: ksoftirqd/%u
+Purpose: Execute softirq handlers when threaded or when under heavy load.
+To reduce its OS jitter, each softirq vector must be handled
+separately as follows:
+TIMER_SOFTIRQ: Do all of the following:
+1. To the extent possible, keep the CPU out of the kernel when it
+ is non-idle, for example, by avoiding system calls and by forcing
+ both kernel threads and interrupts to execute elsewhere.
+2. Build with CONFIG_HOTPLUG_CPU=y. After boot completes, force
+ the CPU offline, then bring it back online. This forces
+ recurring timers to migrate elsewhere. If you are concerned
+ with multiple CPUs, force them all offline before bringing the
+ first one back online. Once you have onlined the CPUs in question,
+ do not offline any other CPUs, because doing so could force the
+ timer back onto one of the CPUs in question.
+NET_TX_SOFTIRQ and NET_RX_SOFTIRQ: Do all of the following:
+1. Force networking interrupts onto other CPUs.
+2. Initiate any network I/O on other CPUs.
+3. Once your application has started, prevent CPU-hotplug operations
+ from being initiated from tasks that might run on the CPU to
+ be de-jittered. (It is OK to force this CPU offline and then
+ bring it back online before you start your application.)
+BLOCK_SOFTIRQ: Do all of the following:
+1. Force block-device interrupts onto some other CPU.
+2. Initiate any block I/O on other CPUs.
+3. Once your application has started, prevent CPU-hotplug operations
+ from being initiated from tasks that might run on the CPU to
+ be de-jittered. (It is OK to force this CPU offline and then
+ bring it back online before you start your application.)
+BLOCK_IOPOLL_SOFTIRQ: Do all of the following:
+1. Force block-device interrupts onto some other CPU.
+2. Initiate any block I/O and block-I/O polling on other CPUs.
+3. Once your application has started, prevent CPU-hotplug operations
+ from being initiated from tasks that might run on the CPU to
+ be de-jittered. (It is OK to force this CPU offline and then
+ bring it back online before you start your application.)
+TASKLET_SOFTIRQ: Do one or more of the following:
+1. Avoid use of drivers that use tasklets. (Such drivers will contain
+ calls to things like tasklet_schedule().)
+2. Convert all drivers that you must use from tasklets to workqueues.
+3. Force interrupts for drivers using tasklets onto other CPUs,
+ and also do I/O involving these drivers on other CPUs.
+SCHED_SOFTIRQ: Do all of the following:
+1. Avoid sending scheduler IPIs to the CPU to be de-jittered,
+ for example, ensure that at most one runnable kthread is present
+ on that CPU. If a thread that expects to run on the de-jittered
+ CPU awakens, the scheduler will send an IPI that can result in
+ a subsequent SCHED_SOFTIRQ.
+2. Build with CONFIG_RCU_NOCB_CPU=y, CONFIG_RCU_NOCB_CPU_ALL=y,
+ CONFIG_NO_HZ_FULL=y, and, in addition, ensure that the CPU
+ to be de-jittered is marked as an adaptive-ticks CPU using the
+ "nohz_full=" boot parameter. This reduces the number of
+ scheduler-clock interrupts that the de-jittered CPU receives,
+ minimizing its chances of being selected to do the load balancing
+ work that runs in SCHED_SOFTIRQ context.
+3. To the extent possible, keep the CPU out of the kernel when it
+ is non-idle, for example, by avoiding system calls and by
+ forcing both kernel threads and interrupts to execute elsewhere.
+ This further reduces the number of scheduler-clock interrupts
+ received by the de-jittered CPU.
+HRTIMER_SOFTIRQ: Do all of the following:
+1. To the extent possible, keep the CPU out of the kernel when it
+ is non-idle. For example, avoid system calls and force both
+ kernel threads and interrupts to execute elsewhere.
+2. Build with CONFIG_HOTPLUG_CPU=y. Once boot completes, force the
+ CPU offline, then bring it back online. This forces recurring
+ timers to migrate elsewhere. If you are concerned with multiple
+ CPUs, force them all offline before bringing the first one
+ back online. Once you have onlined the CPUs in question, do not
+ offline any other CPUs, because doing so could force the timer
+ back onto one of the CPUs in question.
+RCU_SOFTIRQ: Do at least one of the following:
+1. Offload callbacks and keep the CPU in either dyntick-idle or
+ adaptive-ticks state by doing all of the following:
+ a. Build with CONFIG_RCU_NOCB_CPU=y, CONFIG_RCU_NOCB_CPU_ALL=y,
+ CONFIG_NO_HZ_FULL=y, and, in addition ensure that the CPU
+ to be de-jittered is marked as an adaptive-ticks CPU using
+ the "nohz_full=" boot parameter. Bind the rcuo kthreads
+ to housekeeping CPUs, which can tolerate OS jitter.
+ b. To the extent possible, keep the CPU out of the kernel
+ when it is non-idle, for example, by avoiding system
+ calls and by forcing both kernel threads and interrupts
+ to execute elsewhere.
+2. Enable RCU to do its processing remotely via dyntick-idle by
+ doing all of the following:
+ a. Build with CONFIG_NO_HZ=y and CONFIG_RCU_FAST_NO_HZ=y.
+ b. Ensure that the CPU goes idle frequently, allowing other
+ CPUs to detect that it has passed through an RCU quiescent
+ state. If the kernel is built with CONFIG_NO_HZ_FULL=y,
+ userspace execution also allows other CPUs to detect that
+ the CPU in question has passed through a quiescent state.
+ c. To the extent possible, keep the CPU out of the kernel
+ when it is non-idle, for example, by avoiding system
+ calls and by forcing both kernel threads and interrupts
+ to execute elsewhere.
+
+Name: rcuc/%u
+Purpose: Execute RCU callbacks in CONFIG_RCU_BOOST=y kernels.
+To reduce its OS jitter, do at least one of the following:
+1. Build the kernel with CONFIG_PREEMPT=n. This prevents these
+ kthreads from being created in the first place, and also obviates
+ the need for RCU priority boosting. This approach is feasible
+ for workloads that do not require high degrees of responsiveness.
+2. Build the kernel with CONFIG_RCU_BOOST=n. This prevents these
+ kthreads from being created in the first place. This approach
+ is feasible only if your workload never requires RCU priority
+ boosting, for example, if you ensure frequent idle time on all
+ CPUs that might execute within the kernel.
+3. Build with CONFIG_RCU_NOCB_CPU=y and CONFIG_RCU_NOCB_CPU_ALL=y,
+ which offloads all RCU callbacks to kthreads that can be moved
+ off of CPUs susceptible to OS jitter. This approach prevents the
+ rcuc/%u kthreads from having any work to do, so that they are
+ never awakened.
+4. Ensure that the CPU never enters the kernel, and, in particular,
+ avoid initiating any CPU hotplug operations on this CPU. This is
+ another way of preventing any callbacks from being queued on the
+ CPU, again preventing the rcuc/%u kthreads from having any work
+ to do.
+
+Name: rcuob/%d, rcuop/%d, and rcuos/%d
+Purpose: Offload RCU callbacks from the corresponding CPU.
+To reduce its OS jitter, do at least one of the following:
+1. Use affinity, cgroups, or other mechanism to force these kthreads
+ to execute on some other CPU.
+2. Build with CONFIG_RCU_NOCB_CPUS=n, which will prevent these
+ kthreads from being created in the first place. However, please
+ note that this will not eliminate OS jitter, but will instead
+ shift it to RCU_SOFTIRQ.
+
+Name: watchdog/%u
+Purpose: Detect software lockups on each CPU.
+To reduce its OS jitter, do at least one of the following:
+1. Build with CONFIG_LOCKUP_DETECTOR=n, which will prevent these
+ kthreads from being created in the first place.
+2. Echo a zero to /proc/sys/kernel/watchdog to disable the
+ watchdog timer.
+3. Echo a large number of /proc/sys/kernel/watchdog_thresh in
+ order to reduce the frequency of OS jitter due to the watchdog
+ timer down to a level that is acceptable for your workload.

-1.2 Install ifenslave Control Utility
+1.2 Bonding Control Utility
-------------------------------------
- The ifenslave user level control program is included in the
-kernel source tree, in the file Documentation/networking/ifenslave.c.
-It is generally recommended that you use the ifenslave that
-corresponds to the kernel that you are using (either from the same
-source tree or supplied with the distro), however, ifenslave
-executables from older kernels should function (but features newer
-than the ifenslave release are not supported). Running an ifenslave
-that is newer than the kernel is not supported, and may or may not
-work.
-
- To install ifenslave, do the following:
-
-# gcc -Wall -O -I/usr/src/linux/include ifenslave.c -o ifenslave
-# cp ifenslave /sbin/ifenslave
-
- If your kernel source is not in "/usr/src/linux," then replace
-"/usr/src/linux/include" in the above with the location of your kernel
-source include directory.
-
- You may wish to back up any existing /sbin/ifenslave, or, for
-testing or informal use, tag the ifenslave to the kernel version
-(e.g., name the ifenslave executable /sbin/ifenslave-2.6.10).
-
-IMPORTANT NOTE:
-
- If you omit the "-I" or specify an incorrect directory, you
-may end up with an ifenslave that is incompatible with the kernel
-you're trying to build it for. Some distros (e.g., Red Hat from 7.1
-onwards) do not have /usr/include/linux symbolically linked to the
-default kernel source include directory.
-
-SECOND IMPORTANT NOTE:
- If you plan to configure bonding using sysfs or using the
-/etc/network/interfaces file, you do not need to use ifenslave.
+ It is recommended to configure bonding via iproute2 (netlink)
+or sysfs, the old ifenslave control utility is obsolete.

- * ifenslave.c: Configure network interfaces for parallel routing.

- * Center of Excellence in Space Data and Information Sciences
- * Code 930.5, Goddard Space Flight Center, Greenbelt MD 20771
- *
- * Changes :
- * - 2000/10/02 Willy Tarreau <willy at meta-x.org> :
- * - few fixes. Master's MAC address is now correctly taken from
- * the first device when not previously set ;
- * - detach support : call BOND_RELEASE to detach an enslaved interface.
- * - give a mini-howto from command-line help : # ifenslave -h
- *
- * - 2001/02/16 Chad N. Tindel <ctindel at ieee dot org> :
- * - Master is now brought down before setting the MAC address. In
- * the 2.4 kernel you can't change the MAC address while the device is
- * up because you get EBUSY.
- *
- * - 2001/09/13 Takao Indoh <indou dot takao at jp dot fujitsu dot com>
- * - Added the ability to change the active interface on a mode 1 bond
- * at runtime.
- *
- * - 2001/10/23 Chad N. Tindel <ctindel at ieee dot org> :
- * - No longer set the MAC address of the master. The bond device will
- * take care of this itself
- * - Try the SIOC*** versions of the bonding ioctls before using the
- * old versions
- * - 2002/02/18 Erik Habbinga <erik_habbinga @ hp dot com> :
- * - ifr2.ifr_flags was not initialized in the hwaddr_notset case,
- * SIOCGIFFLAGS now called before hwaddr_notset test
- *
- * - 2002/10/31 Tony Cureington <tony.cureington * hp_com> :
- * - If the master does not have a hardware address when the first slave
- * is enslaved, the master is assigned the hardware address of that
- * slave - there is a comment in bonding.c stating "ifenslave takes
- * care of this now." This corrects the problem of slaves having
- * different hardware addresses in active-backup mode when
- * multiple interfaces are specified on a single ifenslave command
- * (ifenslave bond0 eth0 eth1).
- *
- * - 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Shmulik Hen <shmulik.hen at intel dot com>
- * - Moved setting the slave's mac address and openning it, from
- * the application to the driver. This enables support of modes
- * that need to use the unique mac address of each slave.
- * The driver also takes care of closing the slave and restoring its
- * original mac address upon release.
- * In addition, block possibility of enslaving before the master is up.
- * This prevents putting the system in an undefined state.
- *
- * - 2003/05/01 - Amir Noam <amir.noam at intel dot com>
- * - Added ABI version control to restore compatibility between
- * new/old ifenslave and new/old bonding.
- * - Prevent adding an adapter that is already a slave.
- * Fixes the problem of stalling the transmission and leaving
- * the slave in a down state.
- *
- * - 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Prevent enslaving if the bond device is down.
- * Fixes the problem of leaving the system in unstable state and
- * halting when trying to remove the module.
- * - Close socket on all abnormal exists.
- * - Add versioning scheme that follows that of the bonding driver.
- * current version is 1.0.0 as a base line.
- *
- * - 2003/05/22 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - ifenslave -c was broken; it's now fixed
- * - Fixed problem with routes vanishing from master during enslave
- * processing.
- *
- * - 2003/05/27 - Amir Noam <amir.noam at intel dot com>
- * - Fix backward compatibility issues:
- * For drivers not using ABI versions, slave was set down while
- * it should be left up before enslaving.
- * Also, master was not set down and the default set_mac_address()
- * would fail and generate an error message in the system log.
- * - For opt_c: slave should not be set to the master's setting
- * while it is running. It was already set during enslave. To
- * simplify things, it is now handled separately.
- *
- * - 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Code cleanup and style changes
- * set version to 1.1.0

RPS might be beneficial if the rps_cpus for each queue are the ones that
share the same memory domain as the interrupting CPU for that queue.
+==== RPS Flow Limit
+
+RPS scales kernel receive processing across CPUs without introducing
+reordering. The trade-off to sending all packets from the same flow
+to the same CPU is CPU load imbalance if flows vary in packet rate.
+In the extreme case a single flow dominates traffic. Especially on
+common server workloads with many concurrent connections, such
+behavior indicates a problem such as a misconfiguration or spoofed
+source Denial of Service attack.
+
+Flow Limit is an optional RPS feature that prioritizes small flows
+during CPU contention by dropping packets from large flows slightly
+ahead of those from small flows. It is active only when an RPS or RFS
+destination CPU approaches saturation. Once a CPU's input packet
+queue exceeds half the maximum queue length (as set by sysctl
+net.core.netdev_max_backlog), the kernel starts a per-flow packet
+count over the last 256 packets. If a flow exceeds a set ratio (by
+default, half) of these packets when a new packet arrives, then the
+new packet is dropped. Packets from other flows are still only
+dropped once the input packet queue reaches netdev_max_backlog.
+No packets are dropped when the input packet queue length is below
+the threshold, so flow limit does not sever connections outright:
+even large flows maintain connectivity.
+
+== Interface
+
+Flow limit is compiled in by default (CONFIG_NET_FLOW_LIMIT), but not
+turned on. It is implemented for each CPU independently (to avoid lock
+and cache contention) and toggled per CPU by setting the relevant bit
+in sysctl net.core.flow_limit_cpu_bitmap. It exposes the same CPU
+bitmap interface as rps_cpus (see above) when called from procfs:
+
+ /proc/sys/net/core/flow_limit_cpu_bitmap
+
+Per-flow rate is calculated by hashing each packet into a hashtable
+bucket and incrementing a per-bucket counter. The hash function is
+the same that selects a CPU in RPS, but as the number of buckets can
+be much larger than the number of CPUs, flow limit has finer-grained
+identification of large flows and fewer false positives. The default
+table has 4096 buckets. This value can be modified through sysctl
+
+ net.core.flow_limit_table_len
+
+The value is only consulted when a new table is allocated. Modifying
+it does not update active tables.
+
+== Suggested Configuration
+
+Flow limit is useful on systems with many concurrent connections,
+where a single connection taking up 50% of a CPU indicates a problem.
+In such environments, enable the feature on all CPUs that handle
+network rx interrupts (as set in /proc/irq/N/smp_affinity).
+
+The feature depends on the input packet queue length to exceed
+the flow limit threshold (50%) + the flow history length (256).
+Setting net.core.netdev_max_backlog to either 1000 or 10000
+performed well in experiments.

+After all active master ports are registered with a RapidIO subsystem,

+by user-space command.
4. Enumeration and Discovery
----------------------------
-When rio_init_mports() is called it scans a list of registered master ports and
-calls an enumeration or discovery routine depending on the configured role of a
-master port: host or agent.
+4.1 Overview
+------------
+
+RapidIO subsystem configuration options allow users to specify enumeration and
+discovery methods as statically linked components or loadable modules.
+An enumeration/discovery method implementation and available input parameters
+define how any given method can be attached to available RapidIO mports:
+simply to all available mports OR individually to the specified mport device.
+
+Depending on selected enumeration/discovery build configuration, there are
+several methods to initiate an enumeration and/or discovery process:
+
+ (a) Statically linked enumeration and discovery process can be started
+ automatically during kernel initialization time using corresponding module
+ parameters. This was the original method used since introduction of RapidIO
+ subsystem. Now this method relies on enumerator module parameter which is
+ 'rio-scan.scan' for existing basic enumeration/discovery method.
+ When automatic start of enumeration/discovery is used a user has to ensure
+ that all discovering endpoints are started before the enumerating endpoint
+ and are waiting for enumeration to be completed.
+ Configuration option CONFIG_RAPIDIO_DISC_TIMEOUT defines time that discovering
+ endpoint waits for enumeration to be completed. If the specified timeout
+ expires the discovery process is terminated without obtaining RapidIO network
+ information. NOTE: a timed out discovery process may be restarted later using
+ a user-space command as it is described later if the given endpoint was
+ enumerated successfully.
+
+ (b) Statically linked enumeration and discovery process can be started by
+ a command from user space. This initiation method provides more flexibility
+ for a system startup compared to the option (a) above. After all participating
+ endpoints have been successfully booted, an enumeration process shall be
+ started first by issuing a user-space command, after an enumeration is
+ completed a discovery process can be started on all remaining endpoints.
+
+ (c) Modular enumeration and discovery process can be started by a command from
+ user space. After an enumeration/discovery module is loaded, a network scan
+ process can be started by issuing a user-space command.
+ Similar to the option (b) above, an enumerator has to be started first.
+
+ (d) Modular enumeration and discovery process can be started by a module
+ initialization routine. In this case an enumerating module shall be loaded
+ first.
+
+When a network scan process is started it calls an enumeration or discovery
+routine depending on the configured role of a master port: host or agent.
Enumeration is performed by a master port if it is configured as a host port by
assigning a host device ID greater than or equal to zero. A host device ID is

The enumeration and discovery routines use RapidIO maintenance transactions

-outlined in the RapidIO Interconnect Specification: Annex I [1].
+4.2 Automatic Start of Enumeration and Discovery
+------------------------------------------------
+
+Automatic enumeration/discovery start method is applicable only to built-in
+enumeration/discovery RapidIO configuration selection. To enable automatic
+enumeration/discovery start by existing basic enumerator method set use boot
+command line parameter "rio-scan.scan=1".
+
+This configuration requires synchronized start of all RapidIO endpoints that
+form a network which will be enumerated/discovered. Discovering endpoints have
+to be started before an enumeration starts to ensure that all RapidIO
+controllers have been initialized and are ready to be discovered. Configuration
+parameter CONFIG_RAPIDIO_DISC_TIMEOUT defines time (in seconds) which
+a discovering endpoint will wait for enumeration to be completed.
+
+When automatic enumeration/discovery start is selected, basic method's
+initialization routine calls rio_init_mports() to perform enumeration or
+discovery for all known mport devices.
+
+Depending on RapidIO network size and configuration this automatic
+enumeration/discovery start method may be difficult to use due to the
+requirement for synchronized start of all endpoints.
+
+4.3 User-space Start of Enumeration and Discovery
+-------------------------------------------------
+
+User-space start of enumeration and discovery can be used with built-in and
+modular build configurations. For user-space controlled start RapidIO subsystem
+creates the sysfs write-only attribute file '/sys/bus/rapidio/scan'. To initiate
+an enumeration or discovery process on specific mport device, a user needs to
+write mport_ID (not RapidIO destination ID) into that file. The mport_ID is a
+sequential number (0 ... RIO_MAX_MPORTS) assigned during mport device
+registration. For example for machine with single RapidIO controller, mport_ID
+for that controller always will be 0.
+
+To initiate RapidIO enumeration/discovery on all available mports a user may
+write '-1' (or RIO_MPORT_ANY) into the scan attribute file.
+
+4.4 Basic Enumeration Method
+----------------------------
+
+This is an original enumeration/discovery method which is available since
+first release of RapidIO subsystem code. The enumeration process is
+implemented according to the enumeration algorithm outlined in the RapidIO
+Interconnect Specification: Annex I [1].
+
+This method can be configured as statically linked or loadable module.
+The method's single parameter "scan" allows to trigger the enumeration/discovery
+process from module initialization routine.
+
+This enumeration/discovery method can be started only once and does not support
+unloading if it is built as a module.
The enumeration process traverses the network using a recursive depth-first
algorithm. When a new device is found, the enumerator takes ownership of that

an agent skips RapidIO discovery and continues with remaining kernel
initialization.
+4.5 Adding New Enumeration/Discovery Method
+-------------------------------------------
+
+RapidIO subsystem code organization allows addition of new enumeration/discovery
+methods as new configuration options without significant impact to to the core
+RapidIO code.
+
+A new enumeration/discovery method has to be attached to one or more mport
+devices before an enumeration/discovery process can be started. Normally,
+method's module initialization routine calls rio_register_scan() to attach
+an enumerator to a specified mport device (or devices). The basic enumerator
+implementation demonstrates this process.

+ RAMSTER HOW-TO
+
+Author: Dan Magenheimer
+Ramster maintainer: Konrad Wilk <konrad.wilk@oracle.com>
+
+This is a HOWTO document for ramster which, as of this writing, is in
+the kernel as a subdirectory of zcache in drivers/staging, called ramster.
+(Zcache can be built with or without ramster functionality.) If enabled
+and properly configured, ramster allows memory capacity load balancing
+across multiple machines in a cluster. Further, the ramster code serves
+as an example of asynchronous access for zcache (as well as cleancache and
+frontswap) that may prove useful for future transcendent memory
+implementations, such as KVM and NVRAM. While ramster works today on
+any network connection that supports kernel sockets, its features may
+become more interesting on future high-speed fabrics/interconnects.
+
+Ramster requires both kernel and userland support. The userland support,
+called ramster-tools, is known to work with EL6-based distros, but is a
+set of poorly-hacked slightly-modified cluster tools based on ocfs2, which
+includes an init file, a config file, and a userland binary that interfaces
+to the kernel. This state of userland support reflects the abysmal userland
+skills of this suitably-embarrassed author; any help/patches to turn
+ramster-tools into more distributable rpms/debs useful for a wider range
+of distros would be appreciated. The source RPM that can be used as a
+starting point is available at:
+ http://oss.oracle.com/projects/tmem/files/RAMster/
+
+As a result of this author's ignorance, userland setup described in this
+HOWTO assumes an EL6 distro and is described in EL6 syntax. Apologies
+if this offends anyone!
+
+Kernel support has only been tested on x86_64. Systems with an active
+ocfs2 filesystem should work, but since ramster leverages a lot of
+code from ocfs2, there may be latent issues. A kernel configuration that
+includes CONFIG_OCFS2_FS should build OK, and should certainly run OK
+if no ocfs2 filesystem is mounted.
+
+This HOWTO demonstrates memory capacity load balancing for a two-node
+cluster, where one node called the "local" node becomes overcommitted
+and the other node called the "remote" node provides additional RAM
+capacity for use by the local node. Ramster is capable of more complex
+topologies; see the last section titled "ADVANCED RAMSTER TOPOLOGIES".
+
+If you find any terms in this HOWTO unfamiliar or don't understand the
+motivation for ramster, the following LWN reading is recommended:
+-- Transcendent Memory in a Nutshell (lwn.net/Articles/454795)
+-- The future calculus of memory management (lwn.net/Articles/475681)
+And since ramster is built on top of zcache, this article may be helpful:
+-- In-kernel memory compression (lwn.net/Articles/545244)
+
+Now that you've memorized the contents of those articles, let's get started!
+
+A. PRELIMINARY
+
+1) Install two x86_64 Linux systems that are known to work when
+ upgraded to a recent upstream Linux kernel version.
+
+On each system:
+
+2) Configure, build and install, then boot Linux, just to ensure it
+ can be done with an unmodified upstream kernel. Confirm you booted
+ the upstream kernel with "uname -a".
+
+3) If you plan to do any performance testing or unless you plan to
+ test only swapping, the "WasActive" patch is also highly recommended.
+ (Search lkml.org for WasActive, apply the patch, rebuild your kernel.)
+ For a demo or simple testing, the patch can be ignored.
+
+4) Install ramster-tools as root. An x86_64 rpm for EL6-based systems
+ can be found at:
+ http://oss.oracle.com/projects/tmem/files/RAMster/
+ (Sorry but for now, non-EL6 users must recreate ramster-tools on
+ their own from source. See above.)
+
+5) Ensure that debugfs is mounted at each boot. Examples below assume it
+ is mounted at /sys/kernel/debug.
+
+B. BUILDING RAMSTER INTO THE KERNEL
+
+Do the following on each system:
+
+1) Using the kernel configuration mechanism of your choice, change
+ your config to include:
+
+ CONFIG_CLEANCACHE=y
+ CONFIG_FRONTSWAP=y
+ CONFIG_STAGING=y
+ CONFIG_CONFIGFS_FS=y # NOTE: MUST BE y, not m
+ CONFIG_ZCACHE=y
+ CONFIG_RAMSTER=y
+
+ For a linux-3.10 or later kernel, you should also set:
+
+ CONFIG_ZCACHE_DEBUG=y
+ CONFIG_RAMSTER_DEBUG=y
+
+ Before building the kernel please doublecheck your kernel config
+ file to ensure all of the settings are correct.
+
+2) Build this kernel and change your boot file (e.g. /etc/grub.conf)
+ so that the new kernel will boot.
+
+3) Add "zcache" and "ramster" as kernel boot parameters for the new kernel.
+
+4) Reboot each system approximately simultaneously.
+
+5) Check dmesg to ensure there are some messages from ramster, prefixed
+ by "ramster:"
+
+ # dmesg | grep ramster
+
+ You should also see a lot of files in:
+
+ # ls /sys/kernel/debug/zcache
+ # ls /sys/kernel/debug/ramster
+
+ These are mostly counters for various zcache and ramster activities.
+ You should also see files in:
+
+ # ls /sys/kernel/mm/ramster
+
+ These are sysfs files that control ramster as we shall see.
+
+ Ramster now will act as a single-system zcache on each system
+ but doesn't yet know anything about the cluster so can't yet do
+ anything remotely.
+
+C. CONFIGURING THE RAMSTER CLUSTER
+
+This part can be error prone unless you are familiar with clustering
+filesystems. We need to describe the cluster in a /etc/ramster.conf
+file and the init scripts that parse it are extremely picky about
+the syntax.
+
+1) Create a /etc/ramster.conf file and ensure it is identical on both
+ systems. This file mimics the ocfs2 format and there is a good amount
+ of documentation that can be searched for ocfs2.conf, but you can use:
+
+ cluster:
+ name = ramster
+ node_count = 2
+ node:
+ name = system1
+ cluster = ramster
+ number = 0
+ ip_address = my.ip.ad.r1
+ ip_port = 7777
+ node:
+ name = system2
+ cluster = ramster
+ number = 1
+ ip_address = my.ip.ad.r2
+ ip_port = 7777
+
+ You must ensure that the "name" field in the file exactly matches
+ the output of "hostname" on each system; if "hostname" shows a
+ fully-qualified hostname, ensure the name is fully qualified in
+ /etc/ramster.conf. Obviously, substitute my.ip.ad.rx with proper
+ ip addresses.
+
+2) Enable the ramster service and configure it. If you used the
+ EL6 ramster-tools, this would be:
+
+ # chkconfig --add ramster
+ # service ramster configure
+
+ Set "load on boot" to "y", cluster to start is "ramster" (or whatever
+ name you chose in ramster.conf), heartbeat dead threshold as "500",
+ network idle timeout as "1000000". Leave the others as default.
+
+3) Reboot both systems. After reboot, try (assuming EL6 ramster-tools):
+
+ # service ramster status
+
+ You should see "Checking RAMSTER cluster "ramster": Online". If you do
+ not, something is wrong and ramster will not work. Note that you
+ should also see that the driver for "configfs" is loaded and mounted,
+ the driver for ocfs2_dlmfs is not loaded, and some numbers for network
+ parameters. You will also see "Checking RAMSTER heartbeat: Not active".
+ That's all OK.
+
+4) Now you need to start the cluster heartbeat; the cluster is not "up"
+ until all nodes detect a heartbeat. In a real cluster, heartbeat detection
+ is done via a cluster filesystem, but ramster doesn't require one. Some
+ hack-y kernel code in ramster can start the heartbeat for you though if
+ you tell it what nodes are "up". To enable the heartbeat, do:
+
+ # echo 0 > /sys/kernel/mm/ramster/manual_node_up
+ # echo 1 > /sys/kernel/mm/ramster/manual_node_up
+
+ This must be done on BOTH nodes and, to avoid timeouts, must be done
+ approximately concurrently on both nodes. On an EL6 system, it is
+ convenient to put these lines in /etc/rc.local. To confirm that the
+ cluster is now up, on both systems do:
+
+ # dmesg | grep ramster
+
+ You should see ramster "Accepted connection" messages in dmesg on both
+ nodes after this. Note that if you check userland status again with
+
+ # service ramster status
+
+ you will still see "Checking RAMSTER heartbeat: Not active". That's
+ still OK... the ramster kernel heartbeat hack doesn't communicate to
+ userland.
+
+5) You now must tell each node the node to which it should "remotify" pages.
+ On this two node cluster, we will assume the "local" node, node 0, has
+ memory overcommitted and will use ramster to utilize RAM capacity on
+ the "remote node", node 1. To configure this, on node 0, you do:
+
+ # echo 1 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+ You should see "ramster: node 1 set as remotification target" in dmesg
+ on node 0. Again, on EL6, /etc/rc.local is a good place to put this
+ on node 0 so you don't forget to do it at each boot.
+
+6) One more step: By default, the ramster code does not "remotify" any
+ pages; this is primarily for testing purposes, but sometimes it is
+ useful. This may change in the future, but for now, on node 0, you do:
+
+ # echo 1 > /sys/kernel/mm/ramster/pers_remotify_enable
+ # echo 1 > /sys/kernel/mm/ramster/eph_remotify_enable
+
+ The first enables remotifying swap (persistent, aka frontswap) pages,
+ the second enables remotifying of page cache (ephemeral, cleancache)
+ pages.
+
+ On EL6, these lines can also be put in /etc/rc.local (AFTER the
+ node_up lines), or at the beginning of a script that runs a workload.
+
+7) Note that most testing has been done with both/all machines booted
+ roughly simultaneously to avoid cluster timeouts. Ideally, you should
+ do this too unless you are trying to break ramster rather than just
+ use it. ;-)
+
+D. TESTING RAMSTER
+
+1) Note that ramster has no value unless pages get "remotified". For
+ swap/frontswap/persistent pages, this doesn't happen unless/until
+ the workload would cause swapping to occur, at which point pages
+ are put into frontswap/zcache, and the remotification thread starts
+ working. To get to the point where the system swaps, you either
+ need a workload for which the working set exceeds the RAM in the
+ system; or you need to somehow reduce the amount of RAM one of
+ the system sees. This latter is easy when testing in a VM, but
+ harder on physical systems. In some cases, "mem=xxxM" on the
+ kernel command line restricts memory, but for some values of xxx
+ the kernel may fail to boot. One may also try creating a fixed
+ RAMdisk, doing nothing with it, but ensuring that it eats up a fixed
+ amount of RAM.
+
+2) To see if ramster is working, on the "remote node", node 1, try:
+
+ # grep . /sys/kernel/debug/ramster/foreign_*
+ # # note, that is space-dot-space between grep and the pathname
+
+ to monitor the number (and max) ephemeral and persistent pages
+ that ramster has sent. If these stay at zero, ramster is not working
+ either because the workload on the local node (node 0) isn't creating
+ enough memory pressure or because "remotifying" isn't working. On the
+ local system, node 0, you can watch lots of useful information also.
+ Try:
+
+ grep . /sys/kernel/debug/zcache/*pageframes* \
+ /sys/kernel/debug/zcache/*zbytes* \
+ /sys/kernel/debug/zcache/*zpages* \
+ /sys/kernel/debug/ramster/*remote*
+
+ Of particular note are the remote_*_pages_succ_get counters. These
+ show how many disk reads and/or disk writes have been avoided on the
+ overcommitted local system by storing pages remotely using ramster.
+
+ At the risk of information overload, you can also grep:
+
+ /sys/kernel/debug/cleancache/* and /sys/kernel/debug/frontswap/*
+
+ These show, for example, how many disk reads and/or disk writes have
+ been avoided by using zcache to optimize RAM on the local system.
+
+
+AUTOMATIC SWAP REPATRIATION
+
+You may notice that while the systems are idle, the foreign persistent
+page count on the remote machine slowly decreases. This is because
+ramster implements "frontswap selfshrinking": When possible, swap
+pages that have been remotified are slowly repatriated to the local
+machine. This is so that local RAM can be used when possible and
+so that, in case of remote machine crash, the probability of loss
+of data is reduced.
+
+REBOOTING / POWEROFF
+
+If a system is shut down while some of its swap pages still reside
+on a remote system, the system may lock up during the shutdown
+sequence. This will occur if the network is shut down before the
+swap mechansim is shut down, which is the default ordering on many
+distros. To avoid this annoying problem, simply shut off the swap
+subsystem before starting the shutdown sequence, e.g.:
+
+ # swapoff -a
+ # reboot
+
+Ideally, this swapoff-before-ifdown ordering should be enforced permanently
+using shutdown scripts.
+
+KNOWN PROBLEMS
+
+1) You may periodically see messages such as:
+
+ ramster_r2net, message length problem
+
+ This is harmless but indicates that a node is sending messages
+ containing compressed pages that exceed the maximum for zcache
+ (PAGE_SIZE*15/16). The sender side needs to be fixed.
+
+2) If you see a "No longer connected to node..." message or a "No connection
+ established with node X after N seconds", it is possible you may
+ be in an unrecoverable state. If you are certain all of the
+ appropriate cluster configuration steps described above have been
+ performed, try rebooting the two servers concurrently to see if
+ the cluster starts.
+
+ Note that "Connection to node... shutdown, state 7" is an intermediate
+ connection state. As long as you later see "Accepted connection", the
+ intermediate states are harmless.
+
+3) There are known issues in counting certain values. As a result
+ you may see periodic warnings from the kernel. Almost always you
+ will see "ramster: bad accounting for XXX". There are also "WARN_ONCE"
+ messages. If you see kernel warnings with a tombstone, please report
+ them. They are harmless but reflect bugs that need to be eventually fixed.
+
+ADVANCED RAMSTER TOPOLOGIES
+
+The kernel code for ramster can support up to eight nodes in a cluster,
+but no testing has been done with more than three nodes.
+
+In the example described above, the "remote" node serves as a RAM
+overflow for the "local" node. This can be made symmetric by appropriate
+settings of the sysfs remote_target_nodenum file. For example, by setting:
+
+ # echo 1 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 0, and
+
+ # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 1, each node can serve as a RAM overflow for the other.
+
+For more than two nodes, a "RAM server" can be configured. For a
+three node system, set:
+
+ # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 1, and
+
+ # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 2. Then node 0 is a RAM server for node 1 and node 2.
+
+In this implementation of ramster, any remote node is potentially a single
+point of failure (SPOF). Though the probability of failure is reduced
+by automatic swap repatriation (see above), a proposed future enhancement
+to ramster improves high-availability for the cluster by sending a copy
+of each page of date to two other nodes. Patches welcome!
