+
+Target drivers are kept in a directory specific to the feature they provide,

+
+Synonyms
+--------
+
+As mentioned above, the Linux I2C implementation historically uses the terms
+"adapter" for controller and "client" for target. A number of data structures
+have these synonyms in their name. So, when discussing implementation details,
+you should be aware of these terms as well. The official wording is preferred,
+though.
+
+Outdated terminology
+--------------------
+
+In earlier I2C specifications, controller was named "master" and target was
+named "slave". These terms have been obsoleted with v7 of the specification and
+their use is also discouraged by the Linux Kernel Code of Conduct. You may
+still find them in references to documentation which has not been updated. The
+general attitude, however, is to use the inclusive terms: controller and
+target. Work to replace the old terminology in the Linux Kernel is on-going.

+Introduction of non-executable mfd
+==================================
+:Author:
+ Daniel Verkamp <dverkamp@chromium.org>
+ Jeff Xu <jeffxu@chromium.org>
+
+:Contributor:
+ Aleksa Sarai <cyphar@cyphar.com>
+
+Since Linux introduced the memfd feature, memfds have always had their
+execute bit set, and the memfd_create() syscall doesn't allow setting
+it differently.
+
+However, in a secure-by-default system, such as ChromeOS, (where all
+executables should come from the rootfs, which is protected by verified
+boot), this executable nature of memfd opens a door for NoExec bypass
+and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm
+process created a memfd to share the content with an external process,
+however the memfd is overwritten and used for executing arbitrary code
+and root escalation. [2] lists more VRP of this kind.
+
+On the other hand, executable memfd has its legit use: runc uses memfd’s
+seal and executable feature to copy the contents of the binary then
+execute them. For such a system, we need a solution to differentiate runc's
+use of executable memfds and an attacker's [3].
+
+To address those above:
+ - Let memfd_create() set X bit at creation time.
+ - Let memfd be sealed for modifying X bit when NX is set.
+ - Add a new pid namespace sysctl: vm.memfd_noexec to help applications in
+ migrating and enforcing non-executable MFD.
+
+User API
+========
+``int memfd_create(const char *name, unsigned int flags)``
+
+``MFD_NOEXEC_SEAL``
+ When MFD_NOEXEC_SEAL bit is set in the ``flags``, memfd is created
+ with NX. F_SEAL_EXEC is set and the memfd can't be modified to
+ add X later. MFD_ALLOW_SEALING is also implied.
+ This is the most common case for the application to use memfd.
+
+``MFD_EXEC``
+ When MFD_EXEC bit is set in the ``flags``, memfd is created with X.
+
+Note:
+ ``MFD_NOEXEC_SEAL`` implies ``MFD_ALLOW_SEALING``. In case that
+ an app doesn't want sealing, it can add F_SEAL_SEAL after creation.
+
+
+Sysctl:
+========
+``pid namespaced sysctl vm.memfd_noexec``
+
+The new pid namespaced sysctl vm.memfd_noexec has 3 values:
+
+ - 0: MEMFD_NOEXEC_SCOPE_EXEC
+ memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL acts like
+ MFD_EXEC was set.
+
+ - 1: MEMFD_NOEXEC_SCOPE_NOEXEC_SEAL
+ memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL acts like
+ MFD_NOEXEC_SEAL was set.
+
+ - 2: MEMFD_NOEXEC_SCOPE_NOEXEC_ENFORCED
+ memfd_create() without MFD_NOEXEC_SEAL will be rejected.
+
+The sysctl allows finer control of memfd_create for old software that
+doesn't set the executable bit; for example, a container with
+vm.memfd_noexec=1 means the old software will create non-executable memfd
+by default while new software can create executable memfd by setting
+MFD_EXEC.
+
+The value of vm.memfd_noexec is passed to child namespace at creation
+time. In addition, the setting is hierarchical, i.e. during memfd_create,
+we will search from current ns to root ns and use the most restrictive
+setting.

+results in a VMBus control message that is demultiplexed by

+"Direct Mode". Linux prefers to use Direct Mode when available. Since
+x86/x64 doesn't support per-CPU interrupts, Direct Mode statically
+allocates an x86 interrupt vector (HYPERV_STIMER0_VECTOR) across all CPUs
+and explicitly codes it to call the stimer0 interrupt handler. Hence
+interrupts from stimer0 are recorded on the "HVS" line in /proc/interrupts
+rather than being associated with a Linux IRQ. Clockevents based on the
+virtualized PIT and local APIC timer also work, but Hyper-V stimer0
+is preferred.
The driver for the Hyper-V synthetic system clock and timers is

-VMbus interrupts
+Synthetic Interrupt Controller (synic)
+--------------------------------------
+Hyper-V provides each guest CPU with a synthetic interrupt controller
+that is used by VMBus for host-guest communication. While each synic
+defines 16 synthetic interrupts (SINT), Linux uses only one of the 16
+(VMBUS_MESSAGE_SINT). All interrupts related to communication between
+the Hyper-V host and a guest CPU use that SINT.
+
+The SINT is mapped to a single per-CPU architectural interrupt (i.e,
+an 8-bit x86/x64 interrupt vector, or an arm64 PPI INTID). Because
+each CPU in the guest has a synic and may receive VMBus interrupts,
+they are best modeled in Linux as per-CPU interrupts. This model works
+well on arm64 where a single per-CPU Linux IRQ is allocated for
+VMBUS_MESSAGE_SINT. This IRQ appears in /proc/interrupts as an IRQ labelled
+"Hyper-V VMbus". Since x86/x64 lacks support for per-CPU IRQs, an x86
+interrupt vector is statically allocated (HYPERVISOR_CALLBACK_VECTOR)
+across all CPUs and explicitly coded to call vmbus_isr(). In this case,
+there's no Linux IRQ, and the interrupts are visible in aggregate in
+/proc/interrupts on the "HYP" line.
+
+The synic provides the means to demultiplex the architectural interrupt into
+one or more logical interrupts and route the logical interrupt to the proper
+VMBus handler in Linux. This demultiplexing is done by vmbus_isr() and
+related functions that access synic data structures.
+
+The synic is not modeled in Linux as an irq chip or irq domain,
+and the demultiplexed logical interrupts are not Linux IRQs. As such,
+they don't appear in /proc/interrupts or /proc/irq. The CPU
+affinity for one of these logical interrupts is controlled via an
+entry under /sys/bus/vmbus as described below.

- bool "Enable mlocked memory zeroing on free"
- depends on !KMSAN
- help
- This config has the effect of setting "init_mlocked_on_free=1"
- on the kernel command line. If it is enabled, all mlocked process
- memory is zeroed when freed. This restriction to mlocked memory
- improves performance over "init_on_free" but can still be used to
- protect confidential data like key material from content exposures
- to other processes, as well as live forensics and cold boot attacks.
- Any non-mlocked memory is not cleared before it is reassigned. This
- configuration can be overwritten by setting "init_mlocked_on_free=0"
- on the command line. The "init_on_free" boot option takes
- precedence over "init_mlocked_on_free".

+# Routers rt-1 and rt-2 implement IPv4 L3 VPN services leveraging the SRv6
+# architecture. The key components for such VPNs are: a) SRv6 Encap behavior,
+# b) SRv6 End.DX4 behavior.
+#
+# To explain how an IPv4 L3 VPN based on SRv6 works, let us briefly consider an
+# example where, within the same domain of tenant 100, the host hs-1 pings
+# the host hs-2.
+#
+# First of all, L2 reachability of the host hs-2 is taken into account by
+# the router rt-1 which acts as an arp proxy.
+#
+# When the host hs-1 sends an IPv4 packet destined to hs-2, the router rt-1
+# receives the packet on the internal veth-t100 interface, rt-1 contains the
+# SRv6 Encap route for encapsulating the IPv4 packet in a IPv6 plus the Segment
+# Routing Header (SRH) packet. This packet is sent through the (IPv6) core
+# network up to the router rt-2 that receives it on veth0 interface.
+#
+# The rt-2 router uses the 'localsid' routing table to process incoming
+# IPv6+SRH packets which belong to the VPN of the tenant 100. For each of these
+# packets, the SRv6 End.DX4 behavior removes the outer IPv6+SRH headers and
+# routs the packet to the specified nexthop. Afterwards, the packet is sent to
+# the host hs-2 through the veth-t100 interface.
+#
+# The ping response follows the same processing but this time the role of rt-1
+# and rt-2 are swapped.
+#
+# And when net.netfilter.nf_hooks_lwtunnel is set to 1 in rt-1 or rt-2, and a
+# rpfilter iptables rule is added, SRv6 packets will go through netfilter PREROUTING
+# hooks.
