+Indirect Target Selection (ITS)
+===============================
+
+ITS is a vulnerability in some Intel CPUs that support Enhanced IBRS and were
+released before Alder Lake. ITS may allow an attacker to control the prediction
+of indirect branches and RETs located in the lower half of a cacheline.
+
+ITS is assigned CVE-2024-28956 with a CVSS score of 4.7 (Medium).
+
+Scope of Impact
+---------------
+- **eIBRS Guest/Host Isolation**: Indirect branches in KVM/kernel may still be
+  predicted with unintended target corresponding to a branch in the guest.
+
+- **Intra-Mode BTI**: In-kernel training such as through cBPF or other native
+  gadgets.
+
+- **Indirect Branch Prediction Barrier (IBPB)**: After an IBPB, indirect
+  branches may still be predicted with targets corresponding to direct branches
+  executed prior to the IBPB. /*(DEBLOBBED)*/

+- All affected CPUs enumerate Enhanced IBRS feature.
+- IBPB isolation is affected on all ITS affected CPUs, and need a microcode
+  update for mitigation.
+- None of the affected CPUs enumerate BHI_CTRL which was introduced in Golden
+  Cove (Alder Lake and Sapphire Rapids). This can help guests to determine the
+  host's affected status.
+- Intel Atom CPUs are not affected by ITS.
+
+Mitigation
+----------
+As only the indirect branches and RETs that have their last byte of instruction
+in the lower half of the cacheline are vulnerable to ITS, the basic idea behind
+the mitigation is to not allow indirect branches in the lower half.
+
+This is achieved by relying on existing retpoline support in the kernel, and in
+compilers. ITS-vulnerable retpoline sites are runtime patched to point to newly
+added ITS-safe thunks. These safe thunks consists of indirect branch in the
+second half of the cacheline. Not all retpoline sites are patched to thunks, if
+a retpoline site is evaluated to be ITS-safe, it is replaced with an inline
+indirect branch.
+
+Dynamic thunks
+~~~~~~~~~~~~~~
+From a dynamically allocated pool of safe-thunks, each vulnerable site is
+replaced with a new thunk, such that they get a unique address. This could
+improve the branch prediction accuracy. Also, it is a defense-in-depth measure
+against aliasing.
+
+Note, for simplicity, indirect branches in eBPF programs are always replaced
+with a jump to a static thunk in __x86_indirect_its_thunk_array. If required,
+in future this can be changed to use dynamic thunks.
+
+All vulnerable RETs are replaced with a static thunk, they do not use dynamic
+thunks. This is because RETs get their prediction from RSB mostly that does not
+depend on source address. RETs that underflow RSB may benefit from dynamic
+thunks. But, RETs significantly outnumber indirect branches, and any benefit
+from a unique source address could be outweighed by the increased icache
+footprint and iTLB pressure.
+
+Retpoline
+~~~~~~~~~
+Retpoline sequence also mitigates ITS-unsafe indirect branches. For this
+reason, when retpoline is enabled, ITS mitigation only relocates the RETs to
+safe thunks. Unless user requested the RSB-stuffing mitigation.
+
+RSB Stuffing
+~~~~~~~~~~~~
+RSB-stuffing via Call Depth Tracking is a mitigation for Retbleed RSB-underflow
+attacks. And it also mitigates RETs that are vulnerable to ITS.
+
+Mitigation in guests
+^^^^^^^^^^^^^^^^^^^^
+All guests deploy ITS mitigation by default, irrespective of eIBRS enumeration
+and Family/Model of the guest. This is because eIBRS feature could be hidden
+from a guest. One exception to this is when a guest enumerates BHI_DIS_S, which
+indicates that the guest is running on an unaffected host.
+
+To prevent guests from unnecessarily deploying the mitigation on unaffected
+platforms, Intel has defined ITS_NO bit(62) in MSR IA32_ARCH_CAPABILITIES. When
+a guest sees this bit set, it should not enumerate the ITS bug. Note, this bit
+is not set by any hardware, but is **intended for VMMs to synthesize** it for
+guests as per the host's affected status.
+
+Mitigation options
+^^^^^^^^^^^^^^^^^^
+The ITS mitigation can be controlled using the "indirect_target_selection"
+kernel parameter. The available options are:
+
+   ======== ===================================================================
+   on       (default)  Deploy the "Aligned branch/return thunks" mitigation.
+	    If spectre_v2 mitigation enables retpoline, aligned-thunks are only
+	    deployed for the affected RET instructions. Retpoline mitigates
+	    indirect branches.
+
+   off      Disable ITS mitigation.
+
+   vmexit   Equivalent to "=on" if the CPU is affected by guest/host isolation
+	    part of ITS. Otherwise, mitigation is not deployed. This option is
+	    useful when host userspace is not in the threat model, and only
+	    attacks from guest to host are considered.
+
+   stuff    Deploy RSB-fill mitigation when retpoline is also deployed.
+	    Otherwise, deploy the default mitigation. When retpoline mitigation
+	    is enabled, RSB-stuffing via Call-Depth-Tracking also mitigates
+	    ITS.
+
+   force    Force the ITS bug and deploy the default mitigation.
+   ======== ===================================================================
+
+Sysfs reporting
+---------------
+
+The sysfs file showing ITS mitigation status is:
+
+  /sys/devices/system/cpu/vulnerabilities/indirect_target_selection
+
+Note, microcode mitigation status is not reported in this file.
+
+The possible values in this file are:

+==================================
+Register File Data Sampling (RFDS)
+==================================
+
+Register File Data Sampling (RFDS) is a microarchitectural vulnerability that
+only affects Intel Atom parts(also branded as E-cores). RFDS may allow
+a malicious actor to infer data values previously used in floating point
+registers, vector registers, or integer registers. RFDS does not provide the
+ability to choose which data is inferred. CVE-2023-28746 is assigned to RFDS.
+
+Affected Processors
+===================
+Below is the list of affected Intel processors [#f1]_:
+
+   ===================  ============
+   Common name          Family_Model
+   ===================  ============
+   ATOM_GOLDMONT           06_5CH
+   ATOM_GOLDMONT_D         06_5FH

+   ATOM_GRACEMONT          06_BEH
+   RAPTORLAKE_S            06_BFH
+   ===================  ============
+
+As an exception to this table, Intel Xeon E family parts ALDERLAKE(06_97H) and
+RAPTORLAKE(06_B7H) codenamed Catlow are not affected. They are reported as
+vulnerable in Linux because they share the same family/model with an affected
+part. Unlike their affected counterparts, they do not enumerate RFDS_CLEAR or
+CPUID.HYBRID. This information could be used to distinguish between the
+affected and unaffected parts, but it is deemed not worth adding complexity as
+the reporting is fixed automatically when these parts enumerate RFDS_NO.
+
+Mitigation
+==========
+Intel released a microcode update that enables software to clear sensitive
+information using the VERW instruction. Like MDS, RFDS deploys 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.
+
+Mitigation points
+-----------------
+VERW is executed by the kernel before returning to user space, and by KVM
+before VMentry. None of the affected cores support SMT, so VERW is not required
+at C-state transitions.
+
+New bits in IA32_ARCH_CAPABILITIES
+----------------------------------
+Newer processors and microcode update on existing affected processors added new
+bits to IA32_ARCH_CAPABILITIES MSR. These bits can be used to enumerate
+vulnerability and mitigation capability:
+
+- Bit 27 - RFDS_NO - When set, processor is not affected by RFDS.
+- Bit 28 - RFDS_CLEAR - When set, processor is affected by RFDS, and has the
+  microcode that clears the affected buffers on VERW execution.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The kernel command line allows to control RFDS mitigation at boot time with the
+parameter "reg_file_data_sampling=". The valid arguments are:
+
+  ==========  =================================================================
+  on          If the CPU is vulnerable, enable mitigation; CPU buffer clearing
+              on exit to userspace and before entering a VM.
+  off         Disables mitigation.
+  ==========  =================================================================
+
+Mitigation default is selected by CONFIG_MITIGATION_RFDS.
+
+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/reg_file_data_sampling
+

+       - The processor is vulnerable but microcode is not updated.

+VMSCAPE
+=======
+
+VMSCAPE is a vulnerability that may allow a guest to influence the branch
+prediction in host userspace. It particularly affects hypervisors like QEMU.
+
+Even if a hypervisor may not have any sensitive data like disk encryption keys,
+guest-userspace may be able to attack the guest-kernel using the hypervisor as
+a confused deputy.
+
+Affected processors
+-------------------
+
+The following CPU families are affected by VMSCAPE:
+
+**Intel processors:**
+  - Skylake generation (Parts without Enhanced-IBRS)
+  - Cascade Lake generation - (Parts affected by ITS guest/host separation)
+  - Alder Lake and newer (Parts affected by BHI)
+
+Note that, BHI affected parts that use BHB clearing software mitigation e.g.
+Icelake are not vulnerable to VMSCAPE.
+
+**AMD processors:**
+  - Zen series (families 0x17, 0x19, 0x1a)
+
+** Hygon processors:**
+ - Family 0x18
+
+Mitigation
+----------
+
+Conditional IBPB
+----------------
+
+Kernel tracks when a CPU has run a potentially malicious guest and issues an
+IBPB before the first exit to userspace after VM-exit. If userspace did not run
+between VM-exit and the next VM-entry, no IBPB is issued.
+
+Note that the existing userspace mitigation against Spectre-v2 is effective in
+protecting the userspace. They are insufficient to protect the userspace VMMs
+from a malicious guest. This is because Spectre-v2 mitigations are applied at
+context switch time, while the userspace VMM can run after a VM-exit without a
+context switch.
+
+Vulnerability enumeration and mitigation is not applied inside a guest. This is
+because nested hypervisors should already be deploying IBPB to isolate
+themselves from nested guests.
+
+SMT considerations
+------------------
+
+When Simultaneous Multi-Threading (SMT) is enabled, hypervisors can be
+vulnerable to cross-thread attacks. For complete protection against VMSCAPE
+attacks in SMT environments, STIBP should be enabled.
+
+The kernel will issue a warning if SMT is enabled without adequate STIBP
+protection. Warning is not issued when:
+
+- SMT is disabled
+- STIBP is enabled system-wide
+- Intel eIBRS is enabled (which implies STIBP protection)
+
+System information and options
+------------------------------
+
+The sysfs file showing VMSCAPE mitigation status is:
+
+  /sys/devices/system/cpu/vulnerabilities/vmscape
+
+The possible values in this file are:
+
+ * 'Not affected':
+
+   The processor is not vulnerable to VMSCAPE attacks.
+
+ * 'Vulnerable':
+
+   The processor is vulnerable and no mitigation has been applied.
+
+ * 'Mitigation: IBPB before exit to userspace':
+
+   Conditional IBPB mitigation is enabled. The kernel tracks when a CPU has
+   run a potentially malicious guest and issues an IBPB before the first
+   exit to userspace after VM-exit.
+
+ * 'Mitigation: IBPB on VMEXIT':
+
+   IBPB is issued on every VM-exit. This occurs when other mitigations like
+   RETBLEED or SRSO are already issuing IBPB on VM-exit.
+
+Mitigation control on the kernel command line
+----------------------------------------------
+
+The mitigation can be controlled via the ``vmscape=`` command line parameter:
+
+ * ``vmscape=off``:
+
+   Disable the VMSCAPE mitigation.
+
+ * ``vmscape=ibpb``:
+
+   Enable conditional IBPB mitigation (default when CONFIG_MITIGATION_VMSCAPE=y).
+
+ * ``vmscape=force``:
+
+   Force vulnerability detection and mitigation even on processors that are
+   not known to be affected.

-ensure that struct pages that back P2P memory stay out of code that
-does not have support for them as other code may treat the pages as

 Inline encryption support
 =========================
 
-By default, fscrypt uses the kernel crypto API for all cryptographic
-operations (other than HKDF, which fscrypt partially implements
-itself).  The kernel crypto API supports hardware crypto accelerators,
-but only ones that work in the traditional way where all inputs and
-outputs (e.g. plaintexts and ciphertexts) are in memory.  fscrypt can
-take advantage of such hardware, but the traditional acceleration
-model isn't particularly efficient and fscrypt hasn't been optimized
-for it.

-Instead, many newer systems (especially mobile SoCs) have *inline
-encryption hardware* that can encrypt/decrypt data while it is on its
-way to/from the storage device.  Linux supports inline encryption
-through a set of extensions to the block layer called *blk-crypto*.

+===========================
+Subsystem Trace Points: PCI
+===========================
+
+Overview
+========
+The PCI tracing system provides tracepoints to monitor critical hardware events
+that can impact system performance and reliability. These events normally show
+up here:
+
+	/sys/kernel/tracing/events/pci
+
+Cf. include/trace/events/pci.h for the events definitions.
+
+Available Tracepoints
+=====================
+
+pci_hp_event
+------------
+
+Monitors PCI hotplug events including card insertion/removal and link
+state changes.
+::
+
+    pci_hp_event  "%s slot:%s, event:%s\n"
+
+**Event Types**:
+
+* ``LINK_UP`` - PCIe link established
+* ``LINK_DOWN`` - PCIe link lost
+* ``CARD_PRESENT`` - Card detected in slot
+* ``CARD_NOT_PRESENT`` - Card removed from slot
+
+**Example Usage**::
+
+    # Enable the tracepoint
+    echo 1 > /sys/kernel/debug/tracing/events/pci/pci_hp_event/enable
+
+    # Monitor events (the following output is generated when a device is hotplugged)
+    cat /sys/kernel/debug/tracing/trace_pipe
+       irq/51-pciehp-88      [001] .....  1311.177459: pci_hp_event: 0000:00:02.0 slot:10, event:CARD_PRESENT

+
+pcie_link_event
+---------------
+
+Monitors PCIe link speed changes and provides detailed link status information.
+::
+
+    pcie_link_event  "%s type:%d, reason:%d, cur_bus_speed:%d, max_bus_speed:%d, width:%u, flit_mode:%u, status:%s\n"
+
+**Parameters**:
+
+* ``type`` - PCIe device type (4=Root Port, etc.)
+* ``reason`` - Reason for link change:
+
+  - ``0`` - Link retrain
+  - ``1`` - Bus enumeration
+  - ``2`` - Bandwidth notification enable
+  - ``3`` - Bandwidth notification IRQ
+  - ``4`` - Hotplug event
+
+
+**Example Usage**::
+
+    # Enable the tracepoint
+    echo 1 > /sys/kernel/debug/tracing/events/pci/pcie_link_event/enable
+
+    # Monitor events (the following output is generated when a device is hotplugged)

+==================================
+Tracefs ring-buffer memory mapping
+==================================
+
+:Author: Vincent Donnefort <vdonnefort@google.com>
+
+Overview
+========
+Tracefs ring-buffer memory map provides an efficient method to stream data
+as no memory copy is necessary. The application mapping the ring-buffer becomes
+then a consumer for that ring-buffer, in a similar fashion to trace_pipe.
+
+Memory mapping setup
+====================
+The mapping works with a mmap() of the trace_pipe_raw interface.
+
+The first system page of the mapping contains ring-buffer statistics and
+description. It is referred to as the meta-page. One of the most important
+fields of the meta-page is the reader. It contains the sub-buffer ID which can
+be safely read by the mapper (see ring-buffer-design.rst).
+
+The meta-page is followed by all the sub-buffers, ordered by ascending ID. It is
+therefore effortless to know where the reader starts in the mapping:
+
+.. code-block:: c
+
+        reader_id = meta->reader->id;
+        reader_offset = meta->meta_page_size + reader_id * meta->subbuf_size;
+
+When the application is done with the current reader, it can get a new one using
+the trace_pipe_raw ioctl() TRACE_MMAP_IOCTL_GET_READER. This ioctl also updates
+the meta-page fields.
+
+Limitations
+===========
+When a mapping is in place on a Tracefs ring-buffer, it is not possible to
+either resize it (either by increasing the entire size of the ring-buffer or
+each subbuf). It is also not possible to use snapshot and causes splice to copy
+the ring buffer data instead of using the copyless swap from the ring buffer.
+
+Concurrent readers (either another application mapping that ring-buffer or the
+kernel with trace_pipe) are allowed but not recommended. They will compete for
+the ring-buffer and the output is unpredictable, just like concurrent readers on
+trace_pipe would be.
+
+Example
+=======
+
+.. code-block:: c
+
+        #include <fcntl.h>
+        #include <stdio.h>
+        #include <stdlib.h>

- * 32-bit legacy system call entry.
- *
- * 32-bit x86 Linux system calls traditionally used the INT $0x80
- * instruction.  INT $0x80 lands here.
- *
- * This entry point can be used by 32-bit and 64-bit programs to perform
- * 32-bit system calls.  Instances of INT $0x80 can be found inline in
- * various programs and libraries.  It is also used by the vDSO's
- * __kernel_vsyscall fallback for hardware that doesn't support a faster
- * entry method.  Restarted 32-bit system calls also fall back to INT
- * $0x80 regardless of what instruction was originally used to do the
- * system call.
- *
- * This is considered a slow path.  It is not used by most libc
- * implementations on modern hardware except during process startup.
- *
- * Arguments:
- * eax  system call number
- * ebx  arg1
- * ecx  arg2
- * edx  arg3
- * esi  arg4
- * edi  arg5
- * ebp  arg6
+ * int 0x80 is used by 32 bit mode as a system call entry. Normally idt entries
+ * point to C routines, however since this is a system call interface the branch
+ * history needs to be scrubbed to protect against BHI attacks, and that
+ * scrubbing needs to take place in assembly code prior to entering any C

-	  The value set has the following meanings:
+	  Each policy combines power saving states and features:
+	   - Partial: The Phy logic is powered but is in a reduced power
+                      state. The exit latency from this state is no longer than
+                      10us).

+                      state. The exit latency from this state is potentially
+		      longer, but no longer than 10ms.
+	   - DevSleep: The Phy logic may be powered down. The exit latency from
+	               this state is no longer than 20 ms, unless otherwise
+		       specified by DETO in the device Identify Device Data log.
+	   - HIPM: Host Initiated Power Management (host automatically
+		   transitions to partial and slumber).
+	   - DIPM: Device Initiated Power Management (device automatically
+		   transitions to partial and slumber).
+
+	  The possible values for the default SATA link power management
+	  policies are:
 		0 => Keep firmware settings
-		1 => Maximum performance
-		2 => Medium power
-		3 => Medium power with Device Initiated PM enabled
-		4 => Minimum power
-
-	  Note "Minimum power" is known to cause issues, including disk
-	  corruption, with some disks and should not be used.
+		1 => No power savings (maximum performance)
+		2 => HIPM (Partial)
+		3 => HIPM (Partial) and DIPM (Partial and Slumber)
+		4 => HIPM (Partial and DevSleep) and DIPM (Partial and Slumber)
+		5 => HIPM (Slumber and DevSleep) and DIPM (Partial and Slumber)

+ *

+ * TCP_CHAN_STEER_LO/HI control which TCC is used by TCP channels.
+ * TCP_ADDR_CONFIG.NUM_TCC_BANKS controls how many channels are used.
+ *
+ * For optimal performance:
+ * - Rely on the CHAN_STEER from the golden registers table,
+ *   only skip disabled TCCs but keep the mapping order.
+ * - Limit NUM_TCC_BANKS to number of active TCCs to avoid thrashing,

+ * Framework to handle complex IIO aggregate devices.
+ *
+ * The typical architecture is to have one device as the frontend device which
+ * can be "linked" against one or multiple backend devices. All the IIO and
+ * userspace interface is expected to be registers/managed by the frontend
+ * device which will callback into the backends when needed (to get/set some
+ * configuration that it does not directly control).
+ *
+ *                                           -------------------------------------------------------
+ * ------------------                        | ------------         ------------      -------  FPGA|
+ * |     ADC        |------------------------| | ADC CORE |---------| DMA CORE |------| RAM |      |
+ * | (Frontend/IIO) | Serial Data (eg: LVDS) | |(backend) |---------|          |------|     |      |
+ * |                |------------------------| ------------         ------------      -------      |
+ * ------------------                        -------------------------------------------------------
+ *
+ * The framework interface is pretty simple:
+ *   - Backends should register themselves with devm_iio_backend_register()
+ *   - Frontend devices should get backends with devm_iio_backend_get()
+ *
+ * Also to note that the primary target for this framework are converters like
+ * ADC/DACs so iio_backend_ops will have some operations typical of converter
+ * devices. On top of that, this is "generic" for all IIO which means any kind
+ * of device can make use of the framework. That said, If the iio_backend_ops
+ * struct begins to grow out of control, we can always refactor things so that
+ * the industrialio-backend.c is only left with the really generic stuff. Then,
+ * we can build on top of it depending on the needs.

+/* In Clause 5 of IEEE Std 802-2014, two sublayers of the data link layer (DLL)
+ * of the Open Systems Interconnection basic reference model (OSI/RM) are
+ * described; the medium access control (MAC) and logical link control (LLC)
+ * sublayers. The MAC sublayer is the one facing the physical layer.
+ *
+ * In 8.2 of IEEE Std 802.1Q-2022, the Bridge architecture is described. A
+ * Bridge component comprises a MAC Relay Entity for interconnecting the Ports
+ * of the Bridge, at least two Ports, and higher layer entities with at least a
+ * Spanning Tree Protocol Entity included.
+ *
+ * Each Bridge Port also functions as an end station and shall provide the MAC
+ * Service to an LLC Entity. Each instance of the MAC Service is provided to a
+ * distinct LLC Entity that supports protocol identification, multiplexing, and
+ * demultiplexing, for protocol data unit (PDU) transmission and reception by
+ * one or more higher layer entities.
+ *
+ * It is described in 8.13.9 of IEEE Std 802.1Q-2022 that in a Bridge, the LLC
+ * Entity associated with each Bridge Port is modeled as being directly
+ * connected to the attached Local Area Network (LAN).
+ *
+ * On the switch with CPU port architecture, CPU port functions as Management
+ * Port, and the Management Port functionality is provided by software which
+ * functions as an end station. Software is connected to an IEEE 802 LAN that is
+ * wholly contained within the system that incorporates the Bridge. Software
+ * provides access to the LLC Entity associated with each Bridge Port by the
+ * value of the source port field on the special tag on the frame received by
+ * software.
+ *
+ * We call frames that carry control information to determine the active
+ * topology and current extent of each Virtual Local Area Network (VLAN), i.e.,
+ * spanning tree or Shortest Path Bridging (SPB) and Multiple VLAN Registration
+ * Protocol Data Units (MVRPDUs), and frames from other link constrained
+ * protocols, such as Extensible Authentication Protocol over LAN (EAPOL) and
+ * Link Layer Discovery Protocol (LLDP), link-local frames. They are not
+ * forwarded by a Bridge. Permanently configured entries in the filtering
+ * database (FDB) ensure that such frames are discarded by the Forwarding
+ * Process. In 8.6.3 of IEEE Std 802.1Q-2022, this is described in detail:
+ *
+ * Each of the reserved MAC addresses specified in Table 8-1
+ * (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]) shall be
+ * permanently configured in the FDB in C-VLAN components and ERs.
+ *
+ * Each of the reserved MAC addresses specified in Table 8-2
+ * (01-80-C2-00-00-[01,02,03,04,05,06,07,08,09,0A,0E]) shall be permanently
+ * configured in the FDB in S-VLAN components.
+ *
+ * Each of the reserved MAC addresses specified in Table 8-3
+ * (01-80-C2-00-00-[01,02,04,0E]) shall be permanently configured in the FDB in
+ * TPMR components.
+ *
+ * The FDB entries for reserved MAC addresses shall specify filtering for all
+ * Bridge Ports and all VIDs. Management shall not provide the capability to
+ * modify or remove entries for reserved MAC addresses.
+ *
+ * The addresses in Table 8-1, Table 8-2, and Table 8-3 determine the scope of
+ * propagation of PDUs within a Bridged Network, as follows:
+ *
+ *   The Nearest Bridge group address (01-80-C2-00-00-0E) is an address that no
+ *   conformant Two-Port MAC Relay (TPMR) component, Service VLAN (S-VLAN)
+ *   component, Customer VLAN (C-VLAN) component, or MAC Bridge can forward.
+ *   PDUs transmitted using this destination address, or any other addresses
+ *   that appear in Table 8-1, Table 8-2, and Table 8-3
+ *   (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]), can
+ *   therefore travel no further than those stations that can be reached via a
+ *   single individual LAN from the originating station.
+ *
+ *   The Nearest non-TPMR Bridge group address (01-80-C2-00-00-03), is an
+ *   address that no conformant S-VLAN component, C-VLAN component, or MAC
+ *   Bridge can forward; however, this address is relayed by a TPMR component.
+ *   PDUs using this destination address, or any of the other addresses that
+ *   appear in both Table 8-1 and Table 8-2 but not in Table 8-3
+ *   (01-80-C2-00-00-[00,03,05,06,07,08,09,0A,0B,0C,0D,0F]), will be relayed by
+ *   any TPMRs but will propagate no further than the nearest S-VLAN component,
+ *   C-VLAN component, or MAC Bridge.
+ *
+ *   The Nearest Customer Bridge group address (01-80-C2-00-00-00) is an address
+ *   that no conformant C-VLAN component, MAC Bridge can forward; however, it is
+ *   relayed by TPMR components and S-VLAN components. PDUs using this
+ *   destination address, or any of the other addresses that appear in Table 8-1
+ *   but not in either Table 8-2 or Table 8-3 (01-80-C2-00-00-[00,0B,0C,0D,0F]),
+ *   will be relayed by TPMR components and S-VLAN components but will propagate
+ *   no further than the nearest C-VLAN component or MAC Bridge.
+ *
+ * Because the LLC Entity associated with each Bridge Port is provided via CPU
+ * port, we must not filter these frames but forward them to CPU port.
+ *
+ * In a Bridge, the transmission Port is majorly decided by ingress and egress
+ * rules, FDB, and spanning tree Port State functions of the Forwarding Process.
+ * For link-local frames, only CPU port should be designated as destination port
+ * in the FDB, and the other functions of the Forwarding Process must not
+ * interfere with the decision of the transmission Port. We call this process
+ * trapping frames to CPU port.
+ *
+ * Therefore, on the switch with CPU port architecture, link-local frames must
+ * be trapped to CPU port, and certain link-local frames received by a Port of a
+ * Bridge comprising a TPMR component or an S-VLAN component must be excluded
+ * from it.
+ *
+ * A Bridge of the switch with CPU port architecture cannot comprise a Two-Port
+ * MAC Relay (TPMR) component as a TPMR component supports only a subset of the
+ * functionality of a MAC Bridge. A Bridge comprising two Ports (Management Port
+ * doesn't count) of this architecture will either function as a standard MAC
+ * Bridge or a standard VLAN Bridge.
+ *
+ * Therefore, a Bridge of this architecture can only comprise S-VLAN components,
+ * C-VLAN components, or MAC Bridge components. Since there's no TPMR component,
+ * we don't need to relay PDUs using the destination addresses specified on the
+ * Nearest non-TPMR section, and the proportion of the Nearest Customer Bridge
+ * section where they must be relayed by TPMR components.
+ *
+ * One option to trap link-local frames to CPU port is to add static FDB entries
+ * with CPU port designated as destination port. However, because that
+ * Independent VLAN Learning (IVL) is being used on every VID, each entry only
+ * applies to a single VLAN Identifier (VID). For a Bridge comprising a MAC
+ * Bridge component or a C-VLAN component, there would have to be 16 times 4096
+ * entries. This switch intellectual property can only hold a maximum of 2048
+ * entries. Using this option, there also isn't a mechanism to prevent
+ * link-local frames from being discarded when the spanning tree Port State of
+ * the reception Port is discarding.
+ *
+ * The remaining option is to utilise the BPC, RGAC1, RGAC2, RGAC3, and RGAC4
+ * registers. Whilst this applies to every VID, it doesn't contain all of the
+ * reserved MAC addresses without affecting the remaining Standard Group MAC
+ * Addresses. The REV_UN frame tag utilised using the RGAC4 register covers the
+ * remaining 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F] destination
+ * addresses. It also includes the 01-80-C2-00-00-22 to 01-80-C2-00-00-FF
+ * destination addresses which may be relayed by MAC Bridges or VLAN Bridges.
+ * The latter option provides better but not complete conformance.
+ *
+ * This switch intellectual property also does not provide a mechanism to trap
+ * link-local frames with specific destination addresses to CPU port by Bridge,
+ * to conform to the filtering rules for the distinct Bridge components.
+ *
+ * Therefore, regardless of the type of the Bridge component, link-local frames
+ * with these destination addresses will be trapped to CPU port:
+ *
+ * 01-80-C2-00-00-[00,01,02,03,0E]
+ *
+ * In a Bridge comprising a MAC Bridge component or a C-VLAN component:
+ *
+ *   Link-local frames with these destination addresses won't be trapped to CPU
+ *   port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ *   01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F]
+ *
+ * In a Bridge comprising an S-VLAN component:
+ *
+ *   Link-local frames with these destination addresses will be trapped to CPU
+ *   port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ *   01-80-C2-00-00-00
+ *
+ *   Link-local frames with these destination addresses won't be trapped to CPU
+ *   port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ *   01-80-C2-00-00-[04,05,06,07,08,09,0A]
+ *
+ * To trap link-local frames to CPU port as conformant as this switch
+ * intellectual property can allow, link-local frames are made to be regarded as
+ * Bridge Protocol Data Units (BPDUs). This is because this switch intellectual
+ * property only lets the frames regarded as BPDUs bypass the spanning tree Port
+ * State function of the Forwarding Process.
+ *
+ * The only remaining interference is the ingress rules. When the reception Port
+ * has no PVID assigned on software, VLAN-untagged frames won't be allowed in.
+ * There doesn't seem to be a mechanism on the switch intellectual property to
+ * have link-local frames bypass this function of the Forwarding Process.

+		 * Hardware bug: Future timestamp interrupts won't fire unless

 		 *
-		 * To avoid discarding a valid timestamp that just
-		 * happened at the "wrong" time, we need to confirm
-		 * that there was no timestamp captured, we do that by
-		 * assuming that no two timestamps in sequence have
-		 * the same nanosecond value.
+		 * Workaround: Read TXSTMPH_0 here to enable future interrupts.
+		 * However, this read clears TXTT_0. If a timestamp arrives in
+		 * register 0 after checking TXTT_0 but before this read, it
+		 * would be lost.
 		 *
-		 * So, we read the "low" register, read the "high"
-		 * register (to latch a new timestamp) and read the
-		 * "low" register again, if "old" and "new" versions
-		 * of the "low" register are different, a valid
-		 * timestamp was captured, we can read the "high"
-		 * register again.
+		 * To detect this race: We saved a baseline read of TXSTMPL_0
+		 * before TXTT_0 check. After performing the workaround read of
+		 * TXSTMPH_0, we read TXSTMPL_0 again. Since consecutive
+		 * timestamps never share the same nanosecond value, a change
+		 * between the baseline and new TXSTMPL_0 indicates a timestamp
+		 * arrived during the race window. If so, read the complete

- * @dev: mlx5 device that is requesting the IRQ.
- * @used_cpus: cpumask of bounded cpus by the device
- * @vecidx: vector index to request an IRQ for.
- *
- * Each IRQ is bounded to at most 1 CPU.
- * This function is requesting an IRQ according to the default assignment.
- * The default assignment policy is:

- *
- * On success, this function updates used_cpus mask and returns an irq pointer.
- * In case of an error, an appropriate error pointer is returned.

+/**
+ * ocelot_update_vlan_reclassify_rule() - Make switch aware only to bridge VLAN TPID
+ *
+ * @ocelot: Switch private data structure
+ * @port: Index of ingress port
+ *
+ * IEEE 802.1Q-2018 clauses "5.5 C-VLAN component conformance" and "5.6 S-VLAN
+ * component conformance" suggest that a C-VLAN component should only recognize
+ * and filter on C-Tags, and an S-VLAN component should only recognize and
+ * process based on C-Tags.
+ *
+ * In Linux, as per commit 1a0b20b25732 ("Merge branch 'bridge-next'"), C-VLAN
+ * components are largely represented by a bridge with vlan_protocol 802.1Q,
+ * and S-VLAN components by a bridge with vlan_protocol 802.1ad.
+ *
+ * Currently the driver only offloads vlan_protocol 802.1Q, but the hardware
+ * design is non-conformant, because the switch assigns each frame to a VLAN
+ * based on an entirely different question, as detailed in figure "Basic VLAN
+ * Classification Flow" from its manual and reproduced below.
+ *
+ * Set TAG_TYPE, PCP, DEI, VID to port-default values in VLAN_CFG register
+ * if VLAN_AWARE_ENA[port] and frame has outer tag then:
+ *   if VLAN_INNER_TAG_ENA[port] and frame has inner tag then:
+ *     TAG_TYPE = (Frame.InnerTPID <> 0x8100)
+ *     Set PCP, DEI, VID to values from inner VLAN header
+ *   else:
+ *     TAG_TYPE = (Frame.OuterTPID <> 0x8100)
+ *     Set PCP, DEI, VID to values from outer VLAN header
+ *   if VID == 0 then:
+ *     VID = VLAN_CFG.VLAN_VID
+ *
+ * Summarized, the switch will recognize both 802.1Q and 802.1ad TPIDs as VLAN
+ * "with equal rights", and just set the TAG_TYPE bit to 0 (if 802.1Q) or to 1
+ * (if 802.1ad). It will classify based on whichever of the tags is "outer", no
+ * matter what TPID that may have (or "inner", if VLAN_INNER_TAG_ENA[port]).
+ *
+ * In the VLAN Table, the TAG_TYPE information is not accessible - just the
+ * classified VID is - so it is as if each VLAN Table entry is for 2 VLANs:
+ * C-VLAN X, and S-VLAN X.
+ *
+ * Whereas the Linux bridge behavior is to only filter on frames with a TPID
+ * equal to the vlan_protocol, and treat everything else as VLAN-untagged.
+ *
+ * Consider an ingress packet tagged with 802.1ad VID=3 and 802.1Q VID=5,
+ * received on a bridge vlan_filtering=1 vlan_protocol=802.1Q port. This frame
+ * should be treated as 802.1Q-untagged, and classified to the PVID of that
+ * bridge port. Not to VID=3, and not to VID=5.
+ *
+ * The VCAP IS1 TCAM has everything we need to overwrite the choices made in
+ * the basic VLAN classification pipeline: it can match on TAG_TYPE in the key,
+ * and it can modify the classified VID in the action. Thus, for each port
+ * under a vlan_filtering bridge, we can insert a rule in VCAP IS1 lookup 0 to
+ * match on 802.1ad tagged frames and modify their classified VID to the 802.1Q
+ * PVID of the port. This effectively makes it appear to the outside world as
+ * if those packets were processed as VLAN-untagged.
+ *
+ * The rule needs to be updated each time the bridge PVID changes, and needs
+ * to be deleted if the bridge PVID is deleted, or if the port becomes
+ * VLAN-unaware.

- * stmmac_dt_phy - parse device-tree driver parameters to allocate PHY resources

- * @dev: device pointer
- * Description:
- * The mdio bus will be allocated in case of a phy transceiver is on board;
- * it will be NULL if the fixed-link is configured.
- * If there is the "snps,dwmac-mdio" sub-node the mdio will be allocated
- * in any case (for DSA, mdio must be registered even if fixed-link).
- * The table below sums the supported configurations:
- *	-------------------------------
- *	snps,phy-addr	|     Y
- *	-------------------------------
- *	phy-handle	|     Y
- *	-------------------------------
- *	fixed-link	|     N

- *	fixed-link	|
- *	-------------------------------
+ * stmmac_of_get_mdio() - Gets the MDIO bus from the devicetree.
+ * @np: devicetree node
+ *
+ * The MDIO bus will be searched for in the following ways:
+ * 1. The compatible is "snps,dwc-qos-ethernet-4.10" && a "mdio" named
+ *    child node exists
+ * 2. A child node with the "snps,dwmac-mdio" compatible is present
  *
- * It returns 0 in case of success otherwise -ENODEV.

+	 * PWM: PWM output may not function correctly if the FIFO is empty when
+	 * a new SAR value is programmed
+	 *
+	 * Description:
+	 * When the PWM FIFO is empty, a new value programmed to the PWM Sample
+	 * register (PWM_PWMSAR) will be directly applied even if the current
+	 * timer period has not expired.
+	 *
+	 * If the new SAMPLE value programmed in the PWM_PWMSAR register is
+	 * less than the previous value, and the PWM counter register
+	 * (PWM_PWMCNR) that contains the current COUNT value is greater than
+	 * the new programmed SAMPLE value, the current period will not flip
+	 * the level. This may result in an output pulse with a duty cycle of
+	 * 100%.
+	 *
+	 * Consider a change from
+	 *     ________
+	 *    /        \______/
+	 *    ^      *        ^
+	 * to
+	 *     ____
+	 *    /    \__________/
+	 *    ^               ^
+	 * At the time marked by *, the new write value will be directly applied
+	 * to SAR even the current period is not over if FIFO is empty.
+	 *
+	 *     ________        ____________________
+	 *    /        \______/                    \__________/

+	 *    |<-- old SAR -->|               |<-- new SAR -->|
+	 *
+	 * That is the output is active for a whole period.
+	 *
+	 * Workaround:
+	 * Check new SAR less than old SAR and current counter is in errata
+	 * windows, write extra old SAR into FIFO and new SAR will effect at
+	 * next period.
+	 *
+	 * Sometime period is quite long, such as over 1 second. If add old SAR
+	 * into FIFO unconditional, new SAR have to wait for next period. It
+	 * may be too long.
+	 *
+	 * Turn off the interrupt to ensure that not IRQ and schedule happen
+	 * during above operations. If any irq and schedule happen, counter
+	 * in PWM will be out of data and take wrong action.
+	 *
+	 * Add a safety margin 1.5us because it needs some time to complete
+	 * IO write.
+	 *
+	 * Use writel_relaxed() to minimize the interval between two writes to
+	 * the SAR register to increase the fastest PWM frequency supported.
+	 *
+	 * When the PWM period is longer than 2us(or <500kHz), this workaround

+ * When we leave the debug trap handler we need to reset the keyboard status
+ * (since the original keyboard state gets partially clobbered by kdb use of
+ * the keyboard).
+ *
+ * The path to deliver the reset is somewhat circuitous.
+ *
+ * To deliver the reset we register an input handler, reset the keyboard and
+ * then deregister the input handler. However, to get this done right, we do
+ * have to carefully manage the calling context because we can only register
+ * input handlers from task context.
+ *
+ * In particular we need to trigger the action from the debug trap handler with
+ * all its NMI and/or NMI-like oddities. To solve this the kgdboc trap exit code
+ * (the "post_exception" callback) uses irq_work_queue(), which is NMI-safe, to
+ * schedule a callback from a hardirq context. From there we have to defer the
+ * work again, this time using schedule_work(), to get a callback using the
+ * system workqueue, which runs in task context.

- * @dep: endpoint that is being enabled
- *
- * Issue a %DWC3_DEPCMD_DEPSTARTCFG command to @dep. After the command's
- * completion, it will set Transfer Resource for all available endpoints.
- *
- * The assignment of transfer resources cannot perfectly follow the data book
- * due to the fact that the controller driver does not have all knowledge of the
- * configuration in advance. It is given this information piecemeal by the
- * composite gadget framework after every SET_CONFIGURATION and
- * SET_INTERFACE. Trying to follow the databook programming model in this
- * scenario can cause errors. For two reasons:
- *
- * 1) The databook says to do %DWC3_DEPCMD_DEPSTARTCFG for every
- * %USB_REQ_SET_CONFIGURATION and %USB_REQ_SET_INTERFACE (8.1.5). This is
- * incorrect in the scenario of multiple interfaces.
- *
- * 2) The databook does not mention doing more %DWC3_DEPCMD_DEPXFERCFG for new
- * endpoint on alt setting (8.1.6).
- *
- * The following simplified method is used instead:
+ * dwc3_gadget_start_config - reset endpoint resources
+ * @dwc: pointer to the DWC3 context
+ * @resource_index: DEPSTARTCFG.XferRscIdx value (must be 0 or 2)
  *
- * All hardware endpoints can be assigned a transfer resource and this setting
- * will stay persistent until either a core reset or hibernation. So whenever we
- * do a %DWC3_DEPCMD_DEPSTARTCFG(0) we can go ahead and do
- * %DWC3_DEPCMD_DEPXFERCFG for every hardware endpoint as well. We are
- * guaranteed that there are as many transfer resources as endpoints.
+ * Set resource_index=0 to reset all endpoints' resources allocation. Do this as
+ * part of the power-on/soft-reset initialization.
  *
- * This function is called for each endpoint when it is being enabled but is
- * triggered only when called for EP0-out, which always happens first, and which
- * should only happen in one of the above conditions.
+ * Set resource_index=2 to reset only non-control endpoints' resources. Do this
+ * on receiving the SET_CONFIGURATION request or hibernation resume.

-	 * Not recoverable.
+	 * When iterating the extents of the inode, at extent_fiemap(), we may
+	 * find an extent that starts at an offset behind the end offset of the
+	 * previous extent we processed. This happens if fiemap is called
+	 * without FIEMAP_FLAG_SYNC and there are ordered extents completing
+	 * after we had to unlock the file range, release the search path, emit
+	 * the fiemap extents stored in the buffer (cache->entries array) and
+	 * the lock the remainder of the range and re-search the btree.
+	 *
+	 * For example we are in leaf X processing its last item, which is the
+	 * file extent item for file range [512K, 1M[, and after
+	 * btrfs_next_leaf() releases the path, there's an ordered extent that
+	 * completes for the file range [768K, 2M[, and that results in trimming
+	 * the file extent item so that it now corresponds to the file range
+	 * [512K, 768K[ and a new file extent item is inserted for the file
+	 * range [768K, 2M[, which may end up as the last item of leaf X or as
+	 * the first item of the next leaf - in either case btrfs_next_leaf()
+	 * will leave us with a path pointing to the new extent item, for the
+	 * file range [768K, 2M[, since that's the first key that follows the
+	 * last one we processed. So in order not to report overlapping extents
+	 * to user space, we trim the length of the previously cached extent and
+	 * emit it.
 	 *
-	 * NOTE: Physical address can overlap, due to compression
+	 * Upon calling btrfs_next_leaf() we may also find an extent with an
+	 * offset smaller than or equals to cache->offset, and this happens
+	 * when we had a hole or prealloc extent with several delalloc ranges in
+	 * it, but after btrfs_next_leaf() released the path, delalloc was
+	 * flushed and the resulting ordered extents were completed, so we can
+	 * now have found a file extent item for an offset that is smaller than

+ * Paper "A New Algorithm for Identifying Loops in Decompilation"

+ * [1] https://api.semanticscholar.org/CorpusID:15784067
+ *
+ * We use a similar algorithm but because loop nested structure is

+ *
+ * Define topmost loop entry as a first node of the loop traversed in a
+ * depth first search starting from initial state. The goal of the loop
+ * tracking algorithm is to associate topmost loop entries with states
+ * derived from these entries.
+ *
+ * For each step in the DFS states traversal algorithm needs to identify
+ * the following situations:

  *
- * One very subtle but very important aspect is that we *always* simulate NULL
- * condition first (as the current state) before we simulate non-NULL case.
- * This has to do with intricacies of scalar precision tracking. By simulating
- * "exit condition" of iter_next() returning NULL first, we make sure all the
- * relevant precision marks *that will be set **after** we exit iterator loop*
- * are propagated backwards to common parent state of NULL and non-NULL
- * branches. Thanks to that, state equivalence checks done later in forked
- * state, when reaching iter_next() for ACTIVE iterator, can assume that
- * precision marks are finalized and won't change. Because simulating another
- * ACTIVE iterator iteration won't change them (because given same input
- * states we'll end up with exactly same output states which we are currently
- * comparing; and verification after the loop already propagated back what
- * needs to be **additionally** tracked as precise). It's subtle, grok
- * precision tracking for more intuitive understanding.
+ * Iteration convergence logic in is_state_visited() relies on exact
+ * states comparison, which ignores read and precision marks.
+ * This is necessary because read and precision marks are not finalized
+ * while in the loop. Exact comparison might preclude convergence for
+ * simple programs like below:
+ *
+ *     i = 0;
+ *     while(iter_next(&it))
+ *       i++;
+ *
+ * At each iteration step i++ would produce a new distinct state and
+ * eventually instruction processing limit would be reached.
+ *
+ * To avoid such behavior speculatively forget (widen) range for
+ * imprecise scalar registers, if those registers were not precise at the
+ * end of the previous iteration and do not match exactly.
+ *
+ * This is a conservative heuristic that allows to verify wide range of programs,
+ * however it precludes verification of programs that conjure an
+ * imprecise value on the first loop iteration and use it as precise on a second.
+ * For example, the following safe program would fail to verify:
+ *
+ *     struct bpf_num_iter it;
+ *     int arr[10];
+ *     int i = 0, a = 0;

+ *       if (a == 0) {
+ *         a = 1;
+ *         i = 7; // Because i changed verifier would forget
+ *                // it's range on second loop entry.
+ *       } else {
+ *         arr[i] = 42; // This would fail to verify.

+	 *
+	 * Proof: For contradiction assume this is not true, so we can
+	 * re-weight without changing vruntime at !0-lag point.
+	 *
+	 *             Weight	VRuntime   Avg-VRuntime
+	 *     before    w          v            V
+	 *      after    w'         v'           V'
+	 *
+	 * Since lag needs to be preserved through re-weight:
+	 *
+	 *	lag = (V - v)*w = (V'- v')*w', where v = v'
+	 *	==>	V' = (V - v)*w/w' + v		(1)
+	 *
+	 * Let W be the total weight of the entities before reweight,
+	 * since V' is the new weighted average of entities:
+	 *
+	 *	V' = (WV + w'v - wv) / (W + w' - w)	(2)
+	 *
+	 * by using (1) & (2) we obtain:
+	 *
+	 *	(WV + w'v - wv) / (W + w' - w) = (V - v)*w/w' + v
+	 *	==> (WV-Wv+Wv+w'v-wv)/(W+w'-w) = (V - v)*w/w' + v
+	 *	==> (WV - Wv)/(W + w' - w) + v = (V - v)*w/w' + v
+	 *	==>	(V - v)*W/(W + w' - w) = (V - v)*w/w' (3)
+	 *
+	 * Since we are doing at !0-lag point which means V != v, we
+	 * can simplify (3):
+	 *
+	 *	==>	W / (W + w' - w) = w / w'
+	 *	==>	Ww' = Ww + ww' - ww
+	 *	==>	W * (w' - w) = w * (w' - w)
+	 *	==>	W = w	(re-weight indicates w' != w)
+	 *
+	 * So the cfs_rq contains only one entity, hence vruntime of
+	 * the entity @v should always equal to the cfs_rq's weighted
+	 * average vruntime @V, which means we will always re-weight
+	 * at 0-lag point, thus breach assumption. Proof completed.
+	 *
+	 *
+	 * COROLLARY #2: Re-weight does NOT affect weighted average
+	 * vruntime of all the entities.
+	 *
+	 * Proof: According to corollary #1, Eq. (1) should be:
+	 *
+	 *	(V - v)*w = (V' - v')*w'
+	 *	==>    v' = V' - (V - v)*w/w'		(4)
+	 *
+	 * According to the weighted average formula, we have:
+	 *
+	 *	V' = (WV - wv + w'v') / (W - w + w')
+	 *	   = (WV - wv + w'(V' - (V - v)w/w')) / (W - w + w')
+	 *	   = (WV - wv + w'V' - Vw + wv) / (W - w + w')
+	 *	   = (WV + w'V' - Vw) / (W - w + w')
+	 *
+	 *	==>  V'*(W - w + w') = WV + w'V' - Vw
+	 *	==>	V' * (W - w) = (W - w) * V	(5)
+	 *
+	 * If the entity is the only one in the cfs_rq, then reweight
+	 * always occurs at 0-lag point, so V won't change. Or else
+	 * there are other entities, hence W != w, then Eq. (5) turns
+	 * into V' = V. So V won't change in either case, proof done.
+	 *
+	 *
+	 * So according to corollary #1 & #2, the effect of re-weight
+	 * on vruntime should be:
+	 *
+	 *	v' = V' - (V - v) * w / w'		(4)

-	  to generate those numbers securely. This setting ensures that these

-	  are going wrong, so that they might contact developers about fixing
-	  it.
-
-	  Unfortunately, on some models of some architectures getting
-	  a fully seeded CRNG is extremely difficult, and so this can
-	  result in dmesg getting spammed for a surprisingly long
-	  time.  This is really bad from a security perspective, and
-	  so architecture maintainers really need to do what they can
-	  to get the CRNG seeded sooner after the system is booted.
-	  However, since users cannot do anything actionable to
-	  address this, by default this option is disabled.

+	 * Bluetooth Core v5.4, Vol 3, Part A, Section 4: the BR/EDR
+	 * signaling channel has a fixed signaling MTU (MTUsig) whose
+	 * minimum and default is 48 octets.  Section 4.1 says that on
+	 * an MTUExceeded command reject the identifier "shall match
+	 * the first request command in the L2CAP packet" and that
+	 * packets containing only response commands "shall be
+	 * silently discarded".
+	 *
+	 * Linux intentionally deviates from that prescription:
+	 *
+	 *   1. Silently discarding desynchronizes the peer.  The
+	 *      remote stack never learns its responses were dropped,
+	 *      so any state machine waiting on a paired response
+	 *      stalls until its own timer fires.
+	 *
+	 *   2. Locating "the first request command" requires walking
+	 *      command headers past MTUsig, i.e. processing bytes
+	 *      from a packet we have already decided is too large to
+	 *      process.
+	 *
+	 * Reject every over-MTUsig signaling packet with one
+	 * L2CAP_REJ_MTU_EXCEEDED command reject.  The reject's
+	 * reason field is what tells the peer that the whole packet
+	 * was discarded; the identifier value is informational, so
+	 * we use the identifier from the first command header, a
+	 * single fixed-offset byte read.

+ *
+ * Example:
+ *      macvlan0
+ *      br0
+ *  ethX  ethY
+ *
+ * ethX (or Y) receives multicast or broadcast packet containing
+ * an IP packet, not yet in conntrack table.
+ *
+ * 1. skb passes through bridge and fake-ip (br_netfilter)Prerouting.
+ *    -> skb->_nfct now references a unconfirmed entry
+ * 2. skb is broad/mcast packet. bridge now passes clones out on each bridge
+ *    interface.
+ * 3. skb gets passed up the stack.
+ * 4. In macvlan case, macvlan driver retains clone(s) of the mcast skb
+ *    and schedules a work queue to send them out on the lower devices.
+ *
+ *    The clone skb->_nfct is not a copy, it is the same entry as the
+ *    original skb.  The macvlan rx handler then returns RX_HANDLER_PASS.
+ * 5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb.
+ *
+ * The Macvlan broadcast worker and normal confirm path will race.
+ *
+ * This race will not happen if step 2 already confirmed a clone. In that
+ * case later steps perform skb_clone() with skb->_nfct already confirmed (in
+ * hash table).  This works fine.
+ *
+ * But such confirmation won't happen when eb/ip/nftables rules dropped the
+ * packets before they reached the nf_confirm step in postrouting.
+ *
+ * Work around this problem by explicit confirmation of the entry at
+ * LOCAL_IN time, before upper layer has a chance to clone the unconfirmed
+ * entry.

+ * nf_nat_used_tuple - check if proposed nat tuple clashes with existing entry
+ * @tuple: proposed NAT binding
+ * @ignored_conntrack: our (unconfirmed) conntrack entry
+ *
+ * A conntrack entry can be inserted to the connection tracking table
+ * if there is no existing entry with an identical tuple in either direction.
+ *
+ * Example:
+ * INITIATOR -> NAT/PAT -> RESPONDER
+ *
+ * INITIATOR passes through NAT/PAT ("us") and SNAT is done (saddr rewrite).
+ * Then, later, NAT/PAT itself also connects to RESPONDER.
+ *
+ * This will not work if the SNAT done earlier has same IP:PORT source pair.
+ *
+ * Conntrack table has:
+ * ORIGINAL: $IP_INITIATOR:$SPORT -> $IP_RESPONDER:$DPORT
+ * REPLY:    $IP_RESPONDER:$DPORT -> $IP_NAT:$SPORT
+ *
+ * and new locally originating connection wants:
+ * ORIGINAL: $IP_NAT:$SPORT -> $IP_RESPONDER:$DPORT
+ * REPLY:    $IP_RESPONDER:$DPORT -> $IP_NAT:$SPORT
+ *
+ * ... which would mean incoming packets cannot be distinguished between
+ * the existing and the newly added entry (identical IP_CT_DIR_REPLY tuple).
+ *
