*
* Memory Structure:
*
- * To support the needs of the most prominent user of AEAD ciphers, namely
- * IPSEC, the AEAD ciphers have a special memory layout the caller must adhere
- * to.
- *
- * The scatter list pointing to the input data must contain:
- *
- * * for RFC4106 ciphers, the concatenation of
- * associated authentication data || IV || plaintext or ciphertext. Note, the
- * same IV (buffer) is also set with the aead_request_set_crypt call. Note,
- * the API call of aead_request_set_ad must provide the length of the AAD and
- * the IV. The API call of aead_request_set_crypt only points to the size of
- * the input plaintext or ciphertext.
- *
- * * for "normal" AEAD ciphers, the concatenation of
- * associated authentication data || plaintext or ciphertext.
- *
- * It is important to note that if multiple scatter gather list entries form
- * the input data mentioned above, the first entry must not point to a NULL
- * buffer. If there is any potential where the AAD buffer can be NULL, the
- * calling code must contain a precaution to ensure that this does not result
- * in the first scatter gather list entry pointing to a NULL buffer.
+ * The source scatterlist must contain the concatenation of
+ * associated data || plaintext or ciphertext.
+ *
+ * The destination scatterlist has the same layout, except that the plaintext
+ * (resp. ciphertext) will grow (resp. shrink) by the authentication tag size
+ * during encryption (resp. decryption).
+ *
+ * In-place encryption/decryption is enabled by using the same scatterlist
+ * pointer for both the source and destination.
+ *
+ * Even in the out-of-place case, space must be reserved in the destination for
+ * the associated data, even though it won't be written to. This makes the
+ * in-place and out-of-place cases more consistent. It is permissible for the
+ * "destination" associated data to alias the "source" associated data.
+ *
+ * As with the other scatterlist crypto APIs, zero-length scatterlist elements
+ * are not allowed in the used part of the scatterlist. Thus, if there is no
+ * associated data, the first element must point to the plaintext/ciphertext.
+ *
+ * To meet the needs of IPsec, a special quirk applies to rfc4106, rfc4309,
+ * rfc4543, and rfc7539esp ciphers. For these ciphers, the final 'ivsize' bytes
+ * of the associated data buffer must contain a second copy of the IV. This is
+ * in addition to the copy passed to aead_request_set_crypt(). These two IV
+ * copies must not differ; different implementations of the same algorithm may
+ * behave differently in that case. Note that the algorithm might not actually
+ * treat the IV as associated data; nevertheless the length passed to
+ * aead_request_set_ad() must include it.

+ * There are 8 controls available:

+ * These gains are multipliers for each component, in format unsigned 0:4:9 with

+ * 4 offset controls, sliders, for each of the BAYER components: R, B, GR, GB.
+ * These offsets are added/substracted from each component, in format signed
+ * 1:12:0 with a default value of 0 (+/- 0)
+ *
+ * To expose this to userspace, added 8 custom controls, in an auto cluster.
+ *
+ * To summarize the functionality:
+ * The auto cluster switch is the auto white balance control, and it works
+ * like this:
+ * AWB == 1: autowhitebalance is on, the do_white_balance button is inactive,
+ * the gains/offsets are inactive, but volatile and readable.
+ * Thus, the results of the whitebalance algorithm are available to userspace to
+ * read at any time.
+ * AWB == 0: autowhitebalance is off, cluster is in manual mode, user can
+ * configure the gain/offsets directly.
+ * More than that, if the do_white_balance button is
+ * pressed, the driver will perform one-time-adjustment, (preferably with color
+ * checker card) and the userspace can read again the new values.
+ *
+ * With this feature, the userspace can save the coefficients and reinstall them
+ * for example after reboot or reprobing the driver.

+ * When set, the device remains present even when media is not
+ * inserted.
+ * Must not be set for devices which are removed entirely when the
+ * media is removed.
+ *
+ * ``GENHD_FL_CD`` (0x0008): the block device is a CD-ROM-style
+ * device.
+ * Affects responses to the ``CDROM_GET_CAPABILITY`` ioctl.
+ *
+ * ``GENHD_FL_UP`` (0x0010): indicates that the block device is "up",
+ * with a similar meaning to network interfaces.
+ *
+ * ``GENHD_FL_SUPPRESS_PARTITION_INFO`` (0x0020): don't include
+ * partition information in ``/proc/partitions`` or in the output of
+ * printk_all_partitions().
+ * Used for the null block device and some MMC devices.
+ *
+ * ``GENHD_FL_EXT_DEVT`` (0x0040): the driver supports extended
+ * dynamic ``dev_t``, i.e. it wants extended device numbers
+ * (``BLOCK_EXT_MAJOR``).
+ * This affects the maximum number of partitions.
+ *
+ * ``GENHD_FL_NATIVE_CAPACITY`` (0x0080): based on information in the
+ * partition table, the device's capacity has been extended to its
+ * native capacity; i.e. the device has hidden capacity used by one
+ * of the partitions (this is a flag used so that native capacity is
+ * only ever unlocked once).
+ *
+ * ``GENHD_FL_BLOCK_EVENTS_ON_EXCL_WRITE`` (0x0100): event polling is
+ * blocked whenever a writer holds an exclusive lock.
+ *
+ * ``GENHD_FL_NO_PART_SCAN`` (0x0200): partition scanning is disabled.
+ * Used for loop devices in their default settings and some MMC
+ * devices.
+ *
+ * ``GENHD_FL_HIDDEN`` (0x0400): the block device is hidden; it
+ * doesn't produce events, doesn't appear in sysfs, and doesn't have
+ * an associated ``bdev``.
+ * Implies ``GENHD_FL_SUPPRESS_PARTITION_INFO`` and
+ * ``GENHD_FL_NO_PART_SCAN``.
+ * Used for multipath devices.

- * Heterogeneous Memory Management (HMM)
- *
- * See Documentation/vm/hmm.rst for reasons and overview of what HMM is and it
- * is for. Here we focus on the HMM API description, with some explanation of
- * the underlying implementation.
- *
- * Short description: HMM provides a set of helpers to share a virtual address
- * space between CPU and a device, so that the device can access any valid
- * address of the process (while still obeying memory protection). HMM also
- * provides helpers to migrate process memory to device memory, and back. Each
- * set of functionality (address space mirroring, and migration to and from
- * device memory) can be used independently of the other.
- *
- *
- * HMM address space mirroring API:
- *
- * Use HMM address space mirroring if you want to mirror a range of the CPU
- * page tables of a process into a device page table. Here, "mirror" means "keep
- * synchronized". Prerequisites: the device must provide the ability to write-
- * protect its page tables (at PAGE_SIZE granularity), and must be able to
- * recover from the resulting potential page faults.
- *
- * HMM guarantees that at any point in time, a given virtual address points to
- * either the same memory in both CPU and device page tables (that is: CPU and
- * device page tables each point to the same pages), or that one page table (CPU
- * or device) points to no entry, while the other still points to the old page
- * for the address. The latter case happens when the CPU page table update
- * happens first, and then the update is mirrored over to the device page table.
- * This does not cause any issue, because the CPU page table cannot start
- * pointing to a new page until the device page table is invalidated.
- *
- * HMM uses mmu_notifiers to monitor the CPU page tables, and forwards any
- * updates to each device driver that has registered a mirror. It also provides
- * some API calls to help with taking a snapshot of the CPU page table, and to
- * synchronize with any updates that might happen concurrently.
*
- *
- * HMM migration to and from device memory:
- *
- * HMM provides a set of helpers to hotplug device memory as ZONE_DEVICE, with
- * a new MEMORY_DEVICE_PRIVATE type. This provides a struct page for each page
- * of the device memory, and allows the device driver to manage its memory
- * using those struct pages. Having struct pages for device memory makes
- * migration easier. Because that memory is not addressable by the CPU it must
- * never be pinned to the device; in other words, any CPU page fault can always
- * cause the device memory to be migrated (copied/moved) back to regular memory.
- *
- * A new migrate helper (migrate_vma()) has been added (see mm/migrate.c) that
- * allows use of a device DMA engine to perform the copy operation between
- * regular system memory and device memory.
+ * See Documentation/vm/hmm.rst for reasons and overview of what HMM is.

+ * GUP_PIN_COUNTING_BIAS, and the associated functions that use it, overload
+ * the page's refcount so that two separate items are tracked: the original page
+ * reference count, and also a new count of how many pin_user_pages() calls were
+ * made against the page. ("gup-pinned" is another term for the latter).
+ *
+ * With this scheme, pin_user_pages() becomes special: such pages are marked as
+ * distinct from normal pages. As such, the unpin_user_page() call (and its
+ * variants) must be used in order to release gup-pinned pages.
*
- * Pages that were pinned via pin_user_pages*() must be released via either
- * unpin_user_page(), or one of the unpin_user_pages*() routines. This is so
- * that eventually such pages can be separately tracked and uniquely handled. In
- * particular, interactions with RDMA and filesystems need special handling.
+ * Choice of value:
*
- * unpin_user_page() and put_page() are not interchangeable, despite this early
- * implementation that makes them look the same. unpin_user_page() calls must
- * be perfectly matched up with pin*() calls.
+ * By making GUP_PIN_COUNTING_BIAS a power of two, debugging of page reference
+ * counts with respect to pin_user_pages() and unpin_user_page() becomes
+ * simpler, due to the fact that adding an even power of two to the page
+ * refcount has the effect of using only the upper N bits, for the code that
+ * counts up using the bias value. This means that the lower bits are left for
+ * the exclusive use of the original code that increments and decrements by one
+ * (or at least, by much smaller values than the bias value).
+ *
+ * Of course, once the lower bits overflow into the upper bits (and this is
+ * OK, because subtraction recovers the original values), then visual inspection
+ * no longer suffices to directly view the separate counts. However, for normal
+ * applications that don't have huge page reference counts, this won't be an
+ * issue.
+ *
+ * Locking: the lockless algorithm described in page_cache_get_speculative()
+ * and page_cache_gup_pin_speculative() provides safe operation for
+ * get_user_pages and page_mkclean and other calls that race to set up page
+ * table entries.

+ *
+ * For non-huge pages, the return value is partially fuzzy: false is not fuzzy,

+ * GUP_PIN_COUNTING_BIAS worth of normal page references".
+ *
+ * False positives are OK, because: a) it's unlikely for a page to get that many
+ * refcounts, and b) all the callers of this routine are expected to be able to
+ * deal gracefully with a false positive.
+ *
+ * For huge pages, the result will be exactly correct. That's because we have
+ * more tracking data available: the 3rd struct page in the compound page is
+ * used to track the pincount (instead using of the GUP_PIN_COUNTING_BIAS
+ * scheme).
+ *
+ * For more information, please see Documentation/vm/pin_user_pages.rst.

+ * Interface instance description.
+ *
+ * Describes an interface of a MOST device the core driver is bound to.

+ * modify this structure.
+ *
+ * @dev: the actual device
+ * @mod: module
+ * @interface Interface type. \sa most_interface_type.
+ * @description PRELIMINARY.
+ * Unique description of the device instance from point of view of the
+ * interface in free text form (ASCII).
+ * It may be a hexadecimal presentation of the memory address for the MediaLB
+ * IP or USB device ID with USB properties for USB interface, etc.
+ * @num_channels Number of channels and size of the channel_vector.
+ * @channel_vector Properties of the channels.
+ * Array index represents channel ID by the driver.
+ * @configure Callback to change data type for the channel of the
+ * interface instance. May be zero if the instance of the interface is not
+ * configurable. Parameter channel_config describes direction and data
+ * type for the channel, configured by the higher level. The content of
+ * @enqueue Delivers MBO to the HDM for processing.
+ * After HDM completes Rx- or Tx- operation the processed MBO shall
+ * be returned back to the MostCore using completion routine.
+ * The reason to get the MBO delivered from the MostCore after the channel
+ * is poisoned is the re-opening of the channel by the application.
+ * In this case the HDM shall hold MBOs and service the channel as usual.
+ * The HDM must be able to hold at least one MBO for each channel.
+ * The callback returns a negative value on error, otherwise 0.
+ * @poison_channel Informs HDM about closing the channel. The HDM shall
+ * cancel all transfers and synchronously or asynchronously return
+ * all enqueued for this channel MBOs using the completion routine.
+ * The callback returns a negative value on error, otherwise 0.
+ * @request_netinfo: triggers retrieving of network info from the HDM by
+ * means of "Message exchange over MDP/MEP"
+ * The call of the function request_netinfo with the parameter on_netinfo as
+ * NULL prohibits use of the previously obtained function pointer.
+ * @priv Private field used by mostcore to store context information.

+/* Port Group IDs (PGID) are masks of destination ports.
+ *
+ * For L2 forwarding, the switch performs 3 lookups in the PGID table for each
+ * frame, and forwards the frame to the ports that are present in the logical
+ * AND of all 3 PGIDs.
+ *
+ * These PGID lookups are:
+ * - In one of PGID[0-63]: for the destination masks. There are 2 paths by
+ * which the switch selects a destination PGID:
+ * - The {DMAC, VID} is present in the MAC table. In that case, the
+ * destination PGID is given by the DEST_IDX field of the MAC table entry
+ * that matched.
+ * - The {DMAC, VID} is not present in the MAC table (it is unknown). The
+ * frame is disseminated as being either unicast, multicast or broadcast,
+ * and according to that, the destination PGID is chosen as being the
+ * value contained by ANA_FLOODING_FLD_UNICAST,
+ * ANA_FLOODING_FLD_MULTICAST or ANA_FLOODING_FLD_BROADCAST.
+ * The destination PGID can be an unicast set: the first PGIDs, 0 to
+ * ocelot->num_phys_ports - 1, or a multicast set: the PGIDs from
+ * ocelot->num_phys_ports to 63. By convention, a unicast PGID corresponds to
+ * a physical port and has a single bit set in the destination ports mask:
+ * that corresponding to the port number itself. In contrast, a multicast
+ * PGID will have potentially more than one single bit set in the destination
+ * ports mask.
+ * - In one of PGID[64-79]: for the aggregation mask. The switch classifier
+ * dissects each frame and generates a 4-bit Link Aggregation Code which is
+ * used for this second PGID table lookup. The goal of link aggregation is to
+ * hash multiple flows within the same LAG on to different destination ports.
+ * The first lookup will result in a PGID with all the LAG members present in
+ * the destination ports mask, and the second lookup, by Link Aggregation
+ * Code, will ensure that each flow gets forwarded only to a single port out
+ * of that mask (there are no duplicates).
+ * - In one of PGID[80-90]: for the source mask. The third time, the PGID table
+ * is indexed with the ingress port (plus 80). These PGIDs answer the
+ * question "is port i allowed to forward traffic to port j?" If yes, then
+ * BIT(j) of PGID 80+i will be found set. The third PGID lookup can be used
+ * to enforce the L2 forwarding matrix imposed by e.g. a Linux bridge.
+ */
+
+/* Reserve some destination PGIDs at the end of the range:
+ * PGID_CPU: used for whitelisting certain MAC addresses, such as the addresses
+ * of the switch port net devices, towards the CPU port module.
+ * PGID_UC: the flooding destinations for unknown unicast traffic.
+ * PGID_MC: the flooding destinations for broadcast and non-IP multicast
+ * traffic.
+ * PGID_MCIPV4: the flooding destinations for IPv4 multicast traffic.
+ * PGID_MCIPV6: the flooding destinations for IPv6 multicast traffic.

+ *
+ * *ctx* is a pointer to in-kernel struct xdp_buff.
+ *
+ * This helper is similar to **bpf_perf_eventoutput**\ () but
+ * restricted to raw_tracepoint bpf programs.
+ * Return
+ * 0 on success, or a negative error in case of failure.
+ *
+ * u64 bpf_get_netns_cookie(void *ctx)
+ * Description
+ * Retrieve the cookie (generated by the kernel) of the network
+ * namespace the input *ctx* is associated with. The network
+ * namespace cookie remains stable for its lifetime and provides
+ * a global identifier that can be assumed unique. If *ctx* is
+ * NULL, then the helper returns the cookie for the initial
+ * network namespace. The cookie itself is very similar to that
+ * of bpf_get_socket_cookie() helper, but for network namespaces
+ * instead of sockets.
+ * Return
+ * A 8-byte long opaque number.
+ *
+ * u64 bpf_get_current_ancestor_cgroup_id(int ancestor_level)
+ * Description
+ * Return id of cgroup v2 that is ancestor of the cgroup associated
+ * with the current task at the *ancestor_level*. The root cgroup
+ * is at *ancestor_level* zero and each step down the hierarchy
+ * increments the level. If *ancestor_level* == level of cgroup
+ * associated with the current task, then return value will be the
+ * same as that of **bpf_get_current_cgroup_id**\ ().
+ *
+ * The helper is useful to implement policies based on cgroups
+ * that are upper in hierarchy than immediate cgroup associated
+ * with the current task.
+ *
+ * The format of returned id and helper limitations are same as in
+ * **bpf_get_current_cgroup_id**\ ().
+ * Return
+ * The id is returned or 0 in case the id could not be retrieved.
+ *
+ * int bpf_sk_assign(struct sk_buff *skb, struct bpf_sock *sk, u64 flags)
+ * Description
+ * Assign the *sk* to the *skb*. When combined with appropriate
+ * routing configuration to receive the packet towards the socket,
+ * will cause *skb* to be delivered to the specified socket.
+ * Subsequent redirection of *skb* via **bpf_redirect**\ (),
+ * **bpf_clone_redirect**\ () or other methods outside of BPF may
+ * interfere with successful delivery to the socket.
+ *
+ * This operation is only valid from TC ingress path.
+ *
+ * The *flags* argument must be zero.
+ * Return
+ * 0 on success, or a negative errno in case of failure.
+ *
+ * * **-EINVAL** Unsupported flags specified.
+ * * **-ENOENT** Socket is unavailable for assignment.
+ * * **-ENETUNREACH** Socket is unreachable (wrong netns).
+ * * **-EOPNOTSUPP** Unsupported operation, for example a
+ * call from outside of TC ingress.
+ * * **-ESOCKTNOSUPPORT** Socket type not supported (reuseport).
