+Cross-Thread Return Address Predictions
+=======================================
+
+Certain AMD and Hygon processors are subject to a cross-thread return address
+predictions vulnerability. When running in SMT mode and one sibling thread
+transitions out of C0 state, the other sibling thread could use return target
+predictions from the sibling thread that transitioned out of C0.
+
+The Spectre v2 mitigations protect the Linux kernel, as it fills the return
+address prediction entries with safe targets when context switching to the idle
+thread. However, KVM does allow a VMM to prevent exiting guest mode when
+transitioning out of C0. This could result in a guest-controlled return target
+being consumed by the sibling thread.
+
+Affected processors
+-------------------
+
+The following CPUs are vulnerable:
+
+    - AMD Family 17h processors
+    - Hygon Family 18h processors
+
+Related CVEs
+------------
+
+The following CVE entry is related to this issue:
+
+   ==============  =======================================
+   CVE-2022-27672  Cross-Thread Return Address Predictions
+   ==============  =======================================
+
+Problem
+-------
+
+Affected SMT-capable processors support 1T and 2T modes of execution when SMT
+is enabled. In 2T mode, both threads in a core are executing code. For the
+processor core to enter 1T mode, it is required that one of the threads
+requests to transition out of the C0 state. This can be communicated with the
+HLT instruction or with an MWAIT instruction that requests non-C0.
+When the thread re-enters the C0 state, the processor transitions back
+to 2T mode, assuming the other thread is also still in C0 state.
+
+In affected processors, the return address predictor (RAP) is partitioned
+depending on the SMT mode. For instance, in 2T mode each thread uses a private
+16-entry RAP, but in 1T mode, the active thread uses a 32-entry RAP. Upon
+transition between 1T/2T mode, the RAP contents are not modified but the RAP
+pointers (which control the next return target to use for predictions) may
+change. This behavior may result in return targets from one SMT thread being
+used by RET predictions in the sibling thread following a 1T/2T switch. In
+particular, a RET instruction executed immediately after a transition to 1T may
+use a return target from the thread that just became idle. In theory, this
+could lead to information disclosure if the return targets used do not come
+from trustworthy code.
+
+Attack scenarios
+----------------
+
+An attack can be mounted on affected processors by performing a series of CALL
+instructions with targeted return locations and then transitioning out of C0
+state.
+
+Mitigation mechanism
+--------------------
+
+Before entering idle state, the kernel context switches to the idle thread. The
+context switch fills the RAP entries (referred to as the RSB in Linux) with safe
+targets by performing a sequence of CALL instructions.
+
+Prevent a guest VM from directly putting the processor into an idle state by
+intercepting HLT and MWAIT instructions.
+
+Both mitigations are required to fully address this issue.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+
+Use existing Spectre v2 mitigations that will fill the RSB on context switch.
+
+Mitigation control for KVM - module parameter
+---------------------------------------------
+
+By default, the KVM hypervisor mitigates this issue by intercepting guest
+attempts to transition out of C0. A VMM can use the KVM_CAP_X86_DISABLE_EXITS
+capability to override those interceptions, but since this is not common, the
+mitigation that covers this path is not enabled by default.
+
+The mitigation for the KVM_CAP_X86_DISABLE_EXITS capability can be turned on
+using the boolean module parameter mitigate_smt_rsb, e.g.:
+        kvm.mitigate_smt_rsb=1

+GDS - Gather Data Sampling
+==========================
+
+Gather Data Sampling is a hardware vulnerability which allows unprivileged
+speculative access to data which was previously stored in vector registers.
+
+Problem
+-------
+When a gather instruction performs loads from memory, different data elements
+are merged into the destination vector register. However, when a gather
+instruction that is transiently executed encounters a fault, stale data from
+architectural or internal vector registers may get transiently forwarded to the
+destination vector register instead. This will allow a malicious attacker to
+infer stale data using typical side channel techniques like cache timing
+attacks. GDS is a purely sampling-based attack.
+
+The attacker uses gather instructions to infer the stale vector register data.
+The victim does not need to do anything special other than use the vector
+registers. The victim does not need to use gather instructions to be
+vulnerable.
+
+Because the buffers are shared between Hyper-Threads cross Hyper-Thread attacks
+are possible.
+
+Attack scenarios
+----------------
+Without mitigation, GDS can infer stale data across virtually all
+permission boundaries:
+
+	Non-enclaves can infer SGX enclave data
+	Userspace can infer kernel data
+	Guests can infer data from hosts
+	Guest can infer guest from other guests
+	Users can infer data from other users
+
+Because of this, it is important to ensure that the mitigation stays enabled in
+lower-privilege contexts like guests and when running outside SGX enclaves.
+
+The hardware enforces the mitigation for SGX. Likewise, VMMs should  ensure
+that guests are not allowed to disable the GDS mitigation. If a host erred and
+allowed this, a guest could theoretically disable GDS mitigation, mount an
+attack, and re-enable it.
+
+Mitigation mechanism
+--------------------
+This issue is mitigated in microcode. The microcode defines the following new
+bits:
+
+ ================================   ===   ============================
+ IA32_ARCH_CAPABILITIES[GDS_CTRL]   R/O   Enumerates GDS vulnerability
+                                          and mitigation support.
+ IA32_ARCH_CAPABILITIES[GDS_NO]     R/O   Processor is not vulnerable.
+ IA32_MCU_OPT_CTRL[GDS_MITG_DIS]    R/W   Disables the mitigation
+                                          0 by default.
+ IA32_MCU_OPT_CTRL[GDS_MITG_LOCK]   R/W   Locks GDS_MITG_DIS=0. Writes
+                                          to GDS_MITG_DIS are ignored
+                                          Can't be cleared once set.
+ ================================   ===   ============================
+
+GDS can also be mitigated on systems that don't have updated microcode by
+disabling AVX. This can be done by setting gather_data_sampling="force" or
+"clearcpuid=avx" on the kernel command-line.
+
+If used, these options will disable AVX use by turning off XSAVE YMM support.
+However, the processor will still enumerate AVX support.  Userspace that
+does not follow proper AVX enumeration to check both AVX *and* XSAVE YMM
+support will break.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The mitigation can be disabled by setting "gather_data_sampling=off" or
+"mitigations=off" on the kernel command line. Not specifying either will default
+to the mitigation being enabled. Specifying "gather_data_sampling=force" will
+use the microcode mitigation when available or disable AVX on affected systems
+where the microcode hasn't been updated to include the mitigation.
+
+GDS System Information
+------------------------
+The kernel provides vulnerability status information through sysfs. For
+GDS this can be accessed by the following sysfs file:
+
+/sys/devices/system/cpu/vulnerabilities/gather_data_sampling
+
+The possible values contained in this file are:

+=========================================
+Processor MMIO Stale Data Vulnerabilities
+=========================================
+
+Processor MMIO Stale Data Vulnerabilities are a class of memory-mapped I/O
+(MMIO) vulnerabilities that can expose data. The sequences of operations for
+exposing data range from simple to very complex. Because most of the
+vulnerabilities require the attacker to have access to MMIO, many environments
+are not affected. System environments using virtualization where MMIO access is
+provided to untrusted guests may need mitigation. These vulnerabilities are
+not transient execution attacks. However, these vulnerabilities may propagate
+stale data into core fill buffers where the data can subsequently be inferred
+by an unmitigated transient execution attack. Mitigation for these
+vulnerabilities includes a combination of microcode update and software
+changes, depending on the platform and usage model. Some of these mitigations
+are similar to those used to mitigate Microarchitectural Data Sampling (MDS) or
+those used to mitigate Special Register Buffer Data Sampling (SRBDS).
+
+Data Propagators
+================
+Propagators are operations that result in stale data being copied or moved from
+one microarchitectural buffer or register to another. Processor MMIO Stale Data
+Vulnerabilities are operations that may result in stale data being directly
+read into an architectural, software-visible state or sampled from a buffer or
+register.
+
+Fill Buffer Stale Data Propagator (FBSDP)
+-----------------------------------------
+Stale data may propagate from fill buffers (FB) into the non-coherent portion
+of the uncore on some non-coherent writes. Fill buffer propagation by itself
+does not make stale data architecturally visible. Stale data must be propagated
+to a location where it is subject to reading or sampling.
+
+Sideband Stale Data Propagator (SSDP)
+-------------------------------------
+The sideband stale data propagator (SSDP) is limited to the client (including
+Intel Xeon server E3) uncore implementation. The sideband response buffer is
+shared by all client cores. For non-coherent reads that go to sideband
+destinations, the uncore logic returns 64 bytes of data to the core, including
+both requested data and unrequested stale data, from a transaction buffer and
+the sideband response buffer. As a result, stale data from the sideband
+response and transaction buffers may now reside in a core fill buffer.
+
+Primary Stale Data Propagator (PSDP)
+------------------------------------
+The primary stale data propagator (PSDP) is limited to the client (including
+Intel Xeon server E3) uncore implementation. Similar to the sideband response
+buffer, the primary response buffer is shared by all client cores. For some
+processors, MMIO primary reads will return 64 bytes of data to the core fill
+buffer including both requested data and unrequested stale data. This is
+similar to the sideband stale data propagator.
+
+Vulnerabilities
+===============
+Device Register Partial Write (DRPW) (CVE-2022-21166)
+-----------------------------------------------------
+Some endpoint MMIO registers incorrectly handle writes that are smaller than
+the register size. Instead of aborting the write or only copying the correct
+subset of bytes (for example, 2 bytes for a 2-byte write), more bytes than
+specified by the write transaction may be written to the register. On
+processors affected by FBSDP, this may expose stale data from the fill buffers
+of the core that created the write transaction.
+
+Shared Buffers Data Sampling (SBDS) (CVE-2022-21125)
+----------------------------------------------------
+After propagators may have moved data around the uncore and copied stale data
+into client core fill buffers, processors affected by MFBDS can leak data from
+the fill buffer. It is limited to the client (including Intel Xeon server E3)
+uncore implementation.
+
+Shared Buffers Data Read (SBDR) (CVE-2022-21123)
+------------------------------------------------
+It is similar to Shared Buffer Data Sampling (SBDS) except that the data is
+directly read into the architectural software-visible state. It is limited to
+the client (including Intel Xeon server E3) uncore implementation.
+
+Affected Processors
+===================
+Not all the CPUs are affected by all the variants. For instance, most
+processors for the server market (excluding Intel Xeon E3 processors) are
+impacted by only Device Register Partial Write (DRPW).

+
+If a CPU is in the affected processor list, but not affected by a variant, it
+is indicated by new bits in MSR IA32_ARCH_CAPABILITIES. As described in a later
+section, mitigation largely remains the same for all the variants, i.e. to
+clear the CPU fill buffers via VERW instruction.
+
+New bits in MSRs
+================
+Newer processors and microcode update on existing affected processors added new
+bits to IA32_ARCH_CAPABILITIES MSR. These bits can be used to enumerate
+specific variants of Processor MMIO Stale Data vulnerabilities and mitigation
+capability.
+
+MSR IA32_ARCH_CAPABILITIES
+--------------------------
+Bit 13 - SBDR_SSDP_NO - When set, processor is not affected by either the
+	 Shared Buffers Data Read (SBDR) vulnerability or the sideband stale
+	 data propagator (SSDP).
+Bit 14 - FBSDP_NO - When set, processor is not affected by the Fill Buffer
+	 Stale Data Propagator (FBSDP).
+Bit 15 - PSDP_NO - When set, processor is not affected by Primary Stale Data
+	 Propagator (PSDP).
+Bit 17 - FB_CLEAR - When set, VERW instruction will overwrite CPU fill buffer
+	 values as part of MD_CLEAR operations. Processors that do not
+	 enumerate MDS_NO (meaning they are affected by MDS) but that do
+	 enumerate support for both L1D_FLUSH and MD_CLEAR implicitly enumerate
+	 FB_CLEAR as part of their MD_CLEAR support.
+Bit 18 - FB_CLEAR_CTRL - Processor supports read and write to MSR
+	 IA32_MCU_OPT_CTRL[FB_CLEAR_DIS]. On such processors, the FB_CLEAR_DIS
+	 bit can be set to cause the VERW instruction to not perform the
+	 FB_CLEAR action. Not all processors that support FB_CLEAR will support
+	 FB_CLEAR_CTRL.
+
+MSR IA32_MCU_OPT_CTRL
+---------------------
+Bit 3 - FB_CLEAR_DIS - When set, VERW instruction does not perform the FB_CLEAR
+action. This may be useful to reduce the performance impact of FB_CLEAR in
+cases where system software deems it warranted (for example, when performance
+is more critical, or the untrusted software has no MMIO access). Note that
+FB_CLEAR_DIS has no impact on enumeration (for example, it does not change
+FB_CLEAR or MD_CLEAR enumeration) and it may not be supported on all processors
+that enumerate FB_CLEAR.
+
+Mitigation
+==========
+Like MDS, all variants of Processor MMIO Stale Data vulnerabilities  have the
+same mitigation strategy to force the CPU to clear the affected buffers before
+an attacker can extract the secrets.
+
+This is achieved by using the otherwise unused and obsolete VERW instruction in
+combination with a microcode update. The microcode clears the affected CPU
+buffers when the VERW instruction is executed.
+
+Kernel reuses the MDS function to invoke the buffer clearing:
+
+	mds_clear_cpu_buffers()
+
+On MDS affected CPUs, the kernel already invokes CPU buffer clear on
+kernel/userspace, hypervisor/guest and C-state (idle) transitions. No
+additional mitigation is needed on such CPUs.
+
+For CPUs not affected by MDS or TAA, mitigation is needed only for the attacker
+with MMIO capability. Therefore, VERW is not required for kernel/userspace. For
+virtualization case, VERW is only needed at VMENTER for a guest with MMIO
+capability.
+
+Mitigation points
+-----------------
+Return to user space
+^^^^^^^^^^^^^^^^^^^^
+Same mitigation as MDS when affected by MDS/TAA, otherwise no mitigation
+needed.
+
+C-State transition
+^^^^^^^^^^^^^^^^^^
+Control register writes by CPU during C-state transition can propagate data
+from fill buffer to uncore buffers. Execute VERW before C-state transition to
+clear CPU fill buffers.
+
+Guest entry point
+^^^^^^^^^^^^^^^^^
+Same mitigation as MDS when processor is also affected by MDS/TAA, otherwise
+execute VERW at VMENTER only for MMIO capable guests. On CPUs not affected by
+MDS/TAA, guest without MMIO access cannot extract secrets using Processor MMIO
+Stale Data vulnerabilities, so there is no need to execute VERW for such guests.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The kernel command line allows to control the Processor MMIO Stale Data
+mitigations at boot time with the option "mmio_stale_data=". The valid
+arguments for this option are:
+
+  ==========  =================================================================
+  full        If the CPU is vulnerable, enable mitigation; CPU buffer clearing
+              on exit to userspace and when entering a VM. Idle transitions are
+              protected as well. It does not automatically disable SMT.
+  full,nosmt  Same as full, with SMT disabled on vulnerable CPUs. This is the
+              complete mitigation.
+  off         Disables mitigation completely.
+  ==========  =================================================================
+
+If the CPU is affected and mmio_stale_data=off is not supplied on the kernel
+command line, then the kernel selects the appropriate mitigation.
+
+Mitigation status information
+-----------------------------
+The Linux kernel provides a sysfs interface to enumerate the current
+vulnerability status of the system: whether the system is vulnerable, and
+which mitigations are active. The relevant sysfs file is:
+
+	/sys/devices/system/cpu/vulnerabilities/mmio_stale_data

+Speculative Return Stack Overflow (SRSO)
+========================================
+
+This is a mitigation for the speculative return stack overflow (SRSO)
+vulnerability found on AMD processors. The mechanism is by now the well
+known scenario of poisoning CPU functional units - the Branch Target
+Buffer (BTB) and Return Address Predictor (RAP) in this case - and then
+tricking the elevated privilege domain (the kernel) into leaking
+sensitive data.
+
+AMD CPUs predict RET instructions using a Return Address Predictor (aka
+Return Address Stack/Return Stack Buffer). In some cases, a non-architectural
+CALL instruction (i.e., an instruction predicted to be a CALL but is
+not actually a CALL) can create an entry in the RAP which may be used
+to predict the target of a subsequent RET instruction.
+
+The specific circumstances that lead to this varies by microarchitecture
+but the concern is that an attacker can mis-train the CPU BTB to predict
+non-architectural CALL instructions in kernel space and use this to
+control the speculative target of a subsequent kernel RET, potentially
+leading to information disclosure via a speculative side-channel.
+
+The issue is tracked under CVE-2023-20569.

+
+In order to exploit vulnerability, an attacker needs to:
+
+ - gain local access on the machine
+
+ - break kASLR
+
+ - find gadgets in the running kernel in order to use them in the exploit
+
+ - potentially create and pin an additional workload on the sibling
+   thread, depending on the microarchitecture (not necessary on fam 0x19)
+
+ - run the exploit
+
+Considering the performance implications of each mitigation type, the
+default one is 'Mitigation: safe RET' which should take care of most
+attack vectors, including the local User->Kernel one.
+
+As always, the user is advised to keep her/his system up-to-date by
+applying software updates regularly.
+
+The default setting will be reevaluated when needed and especially when
+new attack vectors appear.
+
+As one can surmise, 'Mitigation: safe RET' does come at the cost of some
+performance depending on the workload. If one trusts her/his userspace
+and does not want to suffer the performance impact, one can always
+disable the mitigation with spec_rstack_overflow=off.
+
+Similarly, 'Mitigation: IBPB' is another full mitigation type employing
+an indrect branch prediction barrier after having applied the required
+microcode patch for one's system. This mitigation comes also at
+a performance cost.
+
+Mitigation: safe RET
+--------------------
+
+The mitigation works by ensuring all RET instructions speculate to
+a controlled location, similar to how speculation is controlled in the
+retpoline sequence.  To accomplish this, the __x86_return_thunk forces
+the CPU to mispredict every function return using a 'safe return'
+sequence.
+
+To ensure the safety of this mitigation, the kernel must ensure that the
+safe return sequence is itself free from attacker interference.  In Zen3
+and Zen4, this is accomplished by creating a BTB alias between the
+untraining function srso_alias_untrain_ret() and the safe return
+function srso_alias_safe_ret() which results in evicting a potentially
+poisoned BTB entry and using that safe one for all function returns.
+
+In older Zen1 and Zen2, this is accomplished using a reinterpretation
+technique similar to Retbleed one: srso_untrain_ret() and
+srso_safe_ret().

+			Processor MMIO Stale Data is a class of

+			operation. Exposed data could originate or end in
+			the same CPU buffers as affected by MDS and TAA.
+			Therefore, similar to MDS and TAA, the mitigation
+			is to clear the affected CPU buffers.

+			This parameter controls the mitigation. The
+			options are:

+			full       - Enable mitigation on vulnerable CPUs
+
+			full,nosmt - Enable mitigation and disable SMT on
+				     vulnerable CPUs.

+A notifier callback for OF_OVERLAY_PRE_APPLY, OF_OVERLAY_POST_APPLY, or
+OF_OVERLAY_PRE_REMOVE may store pointers to a device tree node in the overlay
+or its content but these pointers must not persist past the notifier callback
+for OF_OVERLAY_POST_REMOVE.  The memory containing the overlay will be
+kfree()ed after OF_OVERLAY_POST_REMOVE notifiers are called.  Note that the
+memory will be kfree()ed even if the notifier for OF_OVERLAY_POST_REMOVE
+returns an error.
+
+The changeset notifiers in drivers/of/dynamic.c are a second type of notifier
+that could be triggered by applying or removing an overlay.  These notifiers
+are not allowed to store pointers to a device tree node in the overlay
+or its content.  The overlay code does not protect against such pointers
+remaining active when the memory containing the overlay is freed as a result
+of removing the overlay.
+
+Any other code that retains a pointer to the overlay nodes or data is
+considered to be a bug because after removing the overlay the pointer
+will refer to freed memory.
+
+Users of overlays must be especially aware of the overall operations that
+occur on the system to ensure that other kernel code does not retain any
+pointers to the overlay nodes or data.  Any example of an inadvertent use
+of such pointers is if a driver or subsystem module is loaded after an
+overlay has been applied, and the driver or subsystem scans the entire
+devicetree or a large portion of it, including the overlay nodes.

-
-Shortcircuting
---------------
-
-Currently, the implementation of idmapped mounts enforces that the filesystem
-is mounted with the initial idmapping. The reason is simply that none of the
-filesystems that we targeted were mountable with a non-initial idmapping. But
-that might change soon enough. As we've seen above, thanks to the properties of
-idmappings the translation works for both filesystems mounted with the initial
-idmapping and filesystem with non-initial idmappings.
-
-Based on this current restriction to filesystem mounted with the initial
-idmapping two noticeable shortcuts have been taken:
-
-1. We always stash a reference to the initial user namespace in ``struct
-   vfsmount``. Idmapped mounts are thus mounts that have a non-initial user
-   namespace attached to them.
-
-   In order to support idmapped mounts this needs to be changed. Instead of
-   stashing the initial user namespace the user namespace the filesystem was
-   mounted with must be stashed. An idmapped mount is then any mount that has
-   a different user namespace attached then the filesystem was mounted with.
-   This has no user-visible consequences.
-
-2. The translation algorithms in ``mapped_fs*id()`` and ``i_*id_into_mnt()``
-   are simplified.
-
-   Let's consider ``mapped_fs*id()`` first. This function translates the
-   caller's kernel id into a kernel id in the filesystem's idmapping via
-   a mount's idmapping. The full algorithm is::
-
-    mapped_fsuid(kid):
-      /* Map the kernel id up into a userspace id in the mount's idmapping. */
-      from_kuid(mount-idmapping, kid) = uid
-
-      /* Map the userspace id down into a kernel id in the filesystem's idmapping. */
-      make_kuid(filesystem-idmapping, uid) = kuid
-
-   We know that the filesystem is always mounted with the initial idmapping as
-   we enforce this in ``mount_setattr()``. So this can be shortened to::
-
-    mapped_fsuid(kid):
-      /* Map the kernel id up into a userspace id in the mount's idmapping. */
-      from_kuid(mount-idmapping, kid) = uid
-
-      /* Map the userspace id down into a kernel id in the filesystem's idmapping. */
-      KUIDT_INIT(uid) = kuid
-
-   Similarly, for ``i_*id_into_mnt()`` which translated the filesystem's kernel
-   id into a mount's kernel id::
-
-    i_uid_into_mnt(kid):
-      /* Map the kernel id up into a userspace id in the filesystem's idmapping. */
-      from_kuid(filesystem-idmapping, kid) = uid
-
-      /* Map the userspace id down into a kernel id in the mounts's idmapping. */
-      make_kuid(mount-idmapping, uid) = kuid
-
-   Again, we know that the filesystem is always mounted with the initial
-   idmapping as we enforce this in ``mount_setattr()``. So this can be
-   shortened to::
-
-    i_uid_into_mnt(kid):
-      /* Map the kernel id up into a userspace id in the filesystem's idmapping. */
-      __kuid_val(kid) = uid
-
-      /* Map the userspace id down into a kernel id in the mounts's idmapping. */
-      make_kuid(mount-idmapping, uid) = kuid
-
-Handling filesystems mounted with non-initial idmappings requires that the
-translation functions be converted to their full form. They can still be
-shortcircuited on non-idmapped mounts. This has no user-visible consequences.

-
-- a bunch of the hooks in fbcon_ops, maybe the remaining hooks could be called

-Linux DECnet Networking Layer Information
-=========================================
-
-1. Other documentation....
-==========================
-
-   - Project Home Pages
-     - http://www.chygwyn.com/				   - Kernel info
-     - http://linux-decnet.sourceforge.net/                - Userland tools
-     - http://www.sourceforge.net/projects/linux-decnet/   - Status page
-
-2. Configuring the kernel
-=========================
-
-Be sure to turn on the following options:
-
-    - CONFIG_DECNET (obviously)
-    - CONFIG_PROC_FS (to see what's going on)
-    - CONFIG_SYSCTL (for easy configuration)
-
-if you want to try out router support (not properly debugged yet)
-you'll need the following options as well...
-
-    - CONFIG_DECNET_ROUTER (to be able to add/delete routes)
-    - CONFIG_NETFILTER (will be required for the DECnet routing daemon)
-
-Don't turn on SIOCGIFCONF support for DECnet unless you are really sure
-that you need it, in general you won't and it can cause ifconfig to
-malfunction.
-
-Run time configuration has changed slightly from the 2.4 system. If you
-want to configure an endnode, then the simplified procedure is as follows:
-
- - Set the MAC address on your ethernet card before starting _any_ other
-   network protocols.
-
-As soon as your network card is brought into the UP state, DECnet should
-start working. If you need something more complicated or are unsure how
-to set the MAC address, see the next section. Also all configurations which
-worked with 2.4 will work under 2.5 with no change.
-
-3. Command line options
-=======================
-
-You can set a DECnet address on the kernel command line for compatibility
-with the 2.4 configuration procedure, but in general it's not needed any more.
-If you do st a DECnet address on the command line, it has only one purpose
-which is that its added to the addresses on the loopback device.
-
-With 2.4 kernels, DECnet would only recognise addresses as local if they
-were added to the loopback device. In 2.5, any local interface address
-can be used to loop back to the local machine. Of course this does not
-prevent you adding further addresses to the loopback device if you
-want to.
-
-N.B. Since the address list of an interface determines the addresses for
-which "hello" messages are sent, if you don't set an address on the loopback
-interface then you won't see any entries in /proc/net/neigh for the local
-host until such time as you start a connection. This doesn't affect the
-operation of the local communications in any other way though.
-
-The kernel command line takes options looking like the following::
-
-    decnet.addr=1,2
-
-the two numbers are the node address 1,2 = 1.2 For 2.2.xx kernels
-and early 2.3.xx kernels, you must use a comma when specifying the
-DECnet address like this. For more recent 2.3.xx kernels, you may
-use almost any character except space, although a `.` would be the most
-obvious choice :-)
-
-There used to be a third number specifying the node type. This option
-has gone away in favour of a per interface node type. This is now set
-using /proc/sys/net/decnet/conf/<dev>/forwarding. This file can be
-set with a single digit, 0=EndNode, 1=L1 Router and  2=L2 Router.
-
-There are also equivalent options for modules. The node address can
-also be set through the /proc/sys/net/decnet/ files, as can other system
-parameters.
-
-Currently the only supported devices are ethernet and ip_gre. The
-ethernet address of your ethernet card has to be set according to the DECnet
-address of the node in order for it to be autoconfigured (and then appear in
-/proc/net/decnet_dev). There is a utility available at the above
-FTP sites called dn2ethaddr which can compute the correct ethernet
-address to use. The address can be set by ifconfig either before or
-at the time the device is brought up. If you are using RedHat you can
-add the line::
-
-    MACADDR=AA:00:04:00:03:04
-
-or something similar, to /etc/sysconfig/network-scripts/ifcfg-eth0 or
-wherever your network card's configuration lives. Setting the MAC address
-of your ethernet card to an address starting with "hi-ord" will cause a
-DECnet address which matches to be added to the interface (which you can
-verify with iproute2).
-
-The default device for routing can be set through the /proc filesystem
-by setting /proc/sys/net/decnet/default_device to the
-device you want DECnet to route packets out of when no specific route
-is available. Usually this will be eth0, for example::
-
-    echo -n "eth0" >/proc/sys/net/decnet/default_device
-
-If you don't set the default device, then it will default to the first
-ethernet card which has been autoconfigured as described above. You can
-confirm that by looking in the default_device file of course.
-
-There is a list of what the other files under /proc/sys/net/decnet/ do
-on the kernel patch web site (shown above).
-
-4. Run time kernel configuration
-================================
-
-
-This is either done through the sysctl/proc interface (see the kernel web
-pages for details on what the various options do) or through the iproute2
-package in the same way as IPv4/6 configuration is performed.
-
-Documentation for iproute2 is included with the package, although there is
-as yet no specific section on DECnet, most of the features apply to both
-IP and DECnet, albeit with DECnet addresses instead of IP addresses and
-a reduced functionality.
-
-If you want to configure a DECnet router you'll need the iproute2 package
-since its the _only_ way to add and delete routes currently. Eventually
-there will be a routing daemon to send and receive routing messages for
-each interface and update the kernel routing tables accordingly. The
-routing daemon will use netfilter to listen to routing packets, and
-rtnetlink to update the kernels routing tables.
-
-The DECnet raw socket layer has been removed since it was there purely
-for use by the routing daemon which will now use netfilter (a much cleaner
-and more generic solution) instead.
-
-5. How can I tell if its working?
-=================================
-
-Here is a quick guide of what to look for in order to know if your DECnet
-kernel subsystem is working.
-
-   - Is the node address set (see /proc/sys/net/decnet/node_address)
-   - Is the node of the correct type
-     (see /proc/sys/net/decnet/conf/<dev>/forwarding)
-   - Is the Ethernet MAC address of each Ethernet card set to match
-     the DECnet address. If in doubt use the dn2ethaddr utility available
-     at the ftp archive.
-   - If the previous two steps are satisfied, and the Ethernet card is up,
-     you should find that it is listed in /proc/net/decnet_dev and also
-     that it appears as a directory in /proc/sys/net/decnet/conf/. The
-     loopback device (lo) should also appear and is required to communicate
-     within a node.
-   - If you have any DECnet routers on your network, they should appear
-     in /proc/net/decnet_neigh, otherwise this file will only contain the
-     entry for the node itself (if it doesn't check to see if lo is up).
-   - If you want to send to any node which is not listed in the
-     /proc/net/decnet_neigh file, you'll need to set the default device
-     to point to an Ethernet card with connection to a router. This is
-     again done with the /proc/sys/net/decnet/default_device file.
-   - Try starting a simple server and client, like the dnping/dnmirror
-     over the loopback interface. With luck they should communicate.
-     For this step and those after, you'll need the DECnet library
-     which can be obtained from the above ftp sites as well as the
-     actual utilities themselves.
-   - If this seems to work, then try talking to a node on your local
-     network, and see if you can obtain the same results.
-   - At this point you are on your own... :-)
-
-6. How to send a bug report
-===========================
-
-If you've found a bug and want to report it, then there are several things
-you can do to help me work out exactly what it is that is wrong. Useful
-information (_most_ of which _is_ _essential_) includes:
-
- - What kernel version are you running ?
- - What version of the patch are you running ?
- - How far though the above set of tests can you get ?
- - What is in the /proc/decnet* files and /proc/sys/net/decnet/* files ?
- - Which services are you running ?
- - Which client caused the problem ?
- - How much data was being transferred ?
- - Was the network congested ?
- - How can the problem be reproduced ?
- - Can you use tcpdump to get a trace ? (N.B. Most (all?) versions of
-   tcpdump don't understand how to dump DECnet properly, so including
-   the hex listing of the packet contents is _essential_, usually the -x flag.
-   You may also need to increase the length grabbed with the -s flag. The
-   -e flag also provides very useful information (ethernet MAC addresses))
-
-7. MAC FAQ
-==========
-
-A quick FAQ on ethernet MAC addresses to explain how Linux and DECnet
-interact and how to get the best performance from your hardware.
-
-Ethernet cards are designed to normally only pass received network frames
-to a host computer when they are addressed to it, or to the broadcast address.
-
-Linux has an interface which allows the setting of extra addresses for
-an ethernet card to listen to. If the ethernet card supports it, the
-filtering operation will be done in hardware, if not the extra unwanted packets
-received will be discarded by the host computer. In the latter case,
-significant processor time and bus bandwidth can be used up on a busy
-network (see the NAPI documentation for a longer explanation of these
-effects).
-
-DECnet makes use of this interface to allow running DECnet on an ethernet
-card which has already been configured using TCP/IP (presumably using the
-built in MAC address of the card, as usual) and/or to allow multiple DECnet
-addresses on each physical interface. If you do this, be aware that if your
-ethernet card doesn't support perfect hashing in its MAC address filter
-then your computer will be doing more work than required. Some cards
-will simply set themselves into promiscuous mode in order to receive
-packets from the DECnet specified addresses. So if you have one of these
-cards its better to set the MAC address of the card as described above
-to gain the best efficiency. Better still is to use a card which supports
-NAPI as well.
-
-
-8. Mailing list
-===============
-
-If you are keen to get involved in development, or want to ask questions
-about configuration, or even just report bugs, then there is a mailing
-list that you can join, details are at:

+Notes on Oxford Semiconductor PCIe (Tornado) 950 serial port devices
+====================================================================
+
+Oxford Semiconductor PCIe (Tornado) 950 serial port devices are driven
+by a fixed 62.5MHz clock input derived from the 100MHz PCI Express clock.
+
+The baud rate produced by the baud generator is obtained from this input
+frequency by dividing it by the clock prescaler, which can be set to any
+value from 1 to 63.875 in increments of 0.125, and then the usual 16-bit
+divisor is used as with the original 8250, to divide the frequency by a
+value from 1 to 65535.  Finally a programmable oversampling rate is used
+that can take any value from 4 to 16 to divide the frequency further and
+determine the actual baud rate used.  Baud rates from 15625000bps down
+to 0.933bps can be obtained this way.
+
+By default the oversampling rate is set to 16 and the clock prescaler is
+set to 33.875, meaning that the frequency to be used as the reference
+for the usual 16-bit divisor is 115313.653, which is close enough to the
+frequency of 115200 used by the original 8250 for the same values to be
+used for the divisor to obtain the requested baud rates by software that
+is unaware of the extra clock controls available.
+
+The oversampling rate is programmed with the TCR register and the clock
+prescaler is programmed with the CPR/CPR2 register pair[1][2][3][4].
+To switch away from the default value of 33.875 for the prescaler the
+the enhanced mode has to be explicitly enabled though, by setting bit 4
+of the EFR.  In that mode setting bit 7 in the MCR enables the prescaler
+or otherwise it is bypassed as if the value of 1 was used.  Additionally
+writing any value to CPR clears CPR2 for compatibility with old software
+written for older conventional PCI Oxford Semiconductor devices that do
+not have the extra prescaler's 9th bit in CPR2, so the CPR/CPR2 register
+pair has to be programmed in the right order.
+
+By using these parameters rates from 15625000bps down to 1bps can be
+obtained, with either exact or highly-accurate actual bit rates for
+standard and many non-standard rates.
+
+Here are the figures for the standard and some non-standard baud rates
+(including those quoted in Oxford Semiconductor documentation), giving
+the requested rate (r), the actual rate yielded (a) and its deviation
+from the requested rate (d), and the values of the oversampling rate
+(tcr), the clock prescaler (cpr) and the divisor (div) produced by the
+new `get_divisor' handler:

+
+With the baud base set to 15625000 and the unsigned 16-bit UART_DIV_MAX
+limitation imposed by `serial8250_get_baud_rate' standard baud rates
+below 300bps become unavailable in the regular way, e.g. the rate of
+200bps requires the baud base to be divided by 78125 and that is beyond
+the unsigned 16-bit range.  The historic spd_cust feature can still be
+used by encoding the values for, the prescaler, the oversampling rate
+and the clock divisor (DLM/DLL) as follows to obtain such rates if so
+required:
+
+ 31 29 28             20 19   16 15                            0
++-----+-----------------+-------+-------------------------------+
+|0 0 0|    CPR2:CPR     |  TCR  |            DLM:DLL            |
++-----+-----------------+-------+-------------------------------+
+
+Use a value such encoded for the `custom_divisor' field along with the
+ASYNC_SPD_CUST flag set in the `flags' field in `struct serial_struct'
+passed with the TIOCSSERIAL ioctl(2), such as with the setserial(8)
+utility and its `divisor' and `spd_cust' parameters, and the select
+the baud rate of 38400bps.  Note that the value of 0 in TCR sets the
+oversampling rate to 16 and prescaler values below 1 in CPR2/CPR are
+clamped by the driver to 1.
+
+For example the value of 0x1f4004e2 will set CPR2/CPR, TCR and DLM/DLL
+respectively to 0x1f4, 0x0 and 0x04e2, choosing the prescaler value,
+the oversampling rate and the clock divisor of 62.500, 16 and 1250
+respectively.  These parameters will set the baud rate for the serial
+port to 62500000 / 62.500 / 1250 / 16 = 50bps.

+CPU[EAX=1]:ECX[24] (TSC_DEADLINE) is not reported by ``KVM_GET_SUPPORTED_CPUID``.
+It can be enabled if ``KVM_CAP_TSC_DEADLINE_TIMER`` is present and the kernel
+has enabled in-kernel emulation of the local APIC.
+
+CPU topology
+~~~~~~~~~~~~
+
+Several CPUID values include topology information for the host CPU:
+0x0b and 0x1f for Intel systems, 0x8000001e for AMD systems.  Different
+versions of KVM return different values for this information and userspace
+should not rely on it.  Currently they return all zeroes.
+
+If userspace wishes to set up a guest topology, it should be careful that
+the values of these three leaves differ for each CPU.  In particular,
+the APIC ID is found in EDX for all subleaves of 0x0b and 0x1f, and in EAX
+for 0x8000001e; the latter also encodes the core id and node id in bits
+7:0 of EBX and ECX respectively.
+
+Obsolete ioctls and capabilities
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+KVM_CAP_DISABLE_QUIRKS does not let userspace know which quirks are actually
+available.  Use ``KVM_CHECK_EXTENSION(KVM_CAP_DISABLE_QUIRKS2)`` instead if
+available.
+
+Ordering of KVM_GET_*/KVM_SET_* ioctls
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+TBD

- * fast. There is a buffer of random data which is asynchronously checked
- * and filled by a workqueue thread.
- * If there are enough bytes in the buffer the s390_arch_random_generate()
- * just delivers these bytes. Otherwise false is returned until the
- * worker thread refills the buffer.
- * The worker fills the rng buffer by pulling fresh entropy from the
- * high quality (but slow) true hardware random generator. This entropy
- * is then spread over the buffer with an pseudo random generator PRNG.
- * As the arch_get_random_seed_long() fetches 8 bytes and the calling
- * function add_interrupt_randomness() counts this as 1 bit entropy the
- * distribution needs to make sure there is in fact 1 bit entropy contained
- * in 8 bytes of the buffer. The current values pull 32 byte entropy
- * and scatter this into a 2048 byte buffer. So 8 byte in the buffer
- * will contain 1 bit of entropy.
- * The worker thread is rescheduled based on the charge level of the
- * buffer but at least with 500 ms delay to avoid too much CPU consumption.
- * So the max. amount of rng data delivered via arch_get_random_seed is
- * limited to 4k bytes per second.

- * Here follows the implementation of s390_arch_get_random_long().
- *
- * The random longs to be pulled by arch_get_random_long() are
- * prepared in an 4K buffer which is filled from the NIST 800-90
- * compliant s390 drbg. By default the random long buffer is refilled
- * 256 times before the drbg itself needs a reseed. The reseed of the
- * drbg is done with 32 bytes fetched from the high quality (but slow)
- * trng which is assumed to deliver 100% entropy. So the 32 * 8 = 256
- * bits of entropy are spread over 256 * 4KB = 1MB serving 131072
- * arch_get_random_long() invocations before reseeded.
- *
- * How often the 4K random long buffer is refilled with the drbg
- * before the drbg is reseeded can be adjusted. There is a module
- * parameter 's390_arch_rnd_long_drbg_reseed' accessible via
- *   /sys/module/arch_random/parameters/rndlong_drbg_reseed
- * or as kernel command line parameter
- *   arch_random.rndlong_drbg_reseed=<value>
- * This parameter tells how often the drbg fills the 4K buffer before
- * it is re-seeded by fresh entropy from the trng.
- * A value of 16 results in reseeding the drbg at every 16 * 4 KB = 64
- * KB with 32 bytes of fresh entropy pulled from the trng. So a value
- * of 16 would result in 256 bits entropy per 64 KB.
- * A value of 256 results in 1MB of drbg output before a reseed of the
- * drbg is done. So this would spread the 256 bits of entropy among 1MB.
- * Setting this parameter to 0 forces the reseed to take place every
- * time the 4K buffer is depleted, so the entropy rises to 256 bits
- * entropy per 4K or 0.5 bit entropy per arch_get_random_long().  With
- * setting this parameter to negative values all this effort is
- * disabled, arch_get_random long() returns false and thus indicating
- * that the arch_get_random_long() feature is disabled at all.
