for the type. The maximum value of ``BTF_INT_BITS()`` is 128.
The ``BTF_INT_OFFSET()`` specifies the starting bit offset to calculate values
-for this int. For example, a bitfield struct member has: * btf member bit
-offset 100 from the start of the structure, * btf member pointing to an int
-type, * the int type has ``BTF_INT_OFFSET() = 2`` and ``BTF_INT_BITS() = 4``
+for this int. For example, a bitfield struct member has:
+ * btf member bit offset 100 from the start of the structure,
+ * btf member pointing to an int type,
+ * the int type has ``BTF_INT_OFFSET() = 2`` and ``BTF_INT_BITS() = 4``
Then in the struct memory layout, this member will occupy ``4`` bits starting
from bits ``100 + 2 = 102``.
Alternatively, the bitfield struct member can be the following to access the
same bits as the above:
-
* btf member bit offset 102,
* btf member pointing to an int type,
* the int type has ``BTF_INT_OFFSET() = 0`` and ``BTF_INT_BITS() = 4``

+==========================
+VFS FILESYSTEM CONTEXT API
+==========================
-There are four operations for creating a filesystem context and
-one for destroying a context:
+There are four operations for creating a filesystem context and one for
+destroying a context:
- (*) struct fs_context *vfs_new_fs_context(struct file_system_type *fs_type,
- struct dentry *reference,
- unsigned int sb_flags,
- unsigned int sb_flags_mask,
- enum fs_context_purpose purpose);
+ (*) struct fs_context *fs_context_for_mount(
+ struct file_system_type *fs_type,
+ unsigned int sb_flags);
- Create a filesystem context for a given filesystem type and purpose. This
- allocates the filesystem context, sets the superblock flags, initialises
- the security and calls fs_type->init_fs_context() to initialise the
- filesystem private data.
+ Allocate a filesystem context for the purpose of setting up a new mount,
+ whether that be with a new superblock or sharing an existing one. This
+ sets the superblock flags, initialises the security and calls
+ fs_type->init_fs_context() to initialise the filesystem private data.
- reference can be NULL or it may indicate the root dentry of a superblock
- that is going to be reconfigured (FS_CONTEXT_FOR_RECONFIGURE) or
- the automount point that triggered a submount (FS_CONTEXT_FOR_SUBMOUNT).
- This is provided as a source of namespace information.
+ fs_type specifies the filesystem type that will manage the context and
+ sb_flags presets the superblock flags stored therein.
+
+ (*) struct fs_context *fs_context_for_reconfigure(
+ struct dentry *dentry,
+ unsigned int sb_flags,
+ unsigned int sb_flags_mask);
+
+ Allocate a filesystem context for the purpose of reconfiguring an
+ existing superblock. dentry provides a reference to the superblock to be
+ configured. sb_flags and sb_flags_mask indicate which superblock flags
+ need changing and to what.
+
+ (*) struct fs_context *fs_context_for_submount(
+ struct file_system_type *fs_type,
+ struct dentry *reference);
+
+ Allocate a filesystem context for the purpose of creating a new mount for
+ an automount point or other derived superblock. fs_type specifies the
+ filesystem type that will manage the context and the reference dentry
+ supplies the parameters. Namespaces are propagated from the reference
+ dentry's superblock also.
+
+ Note that it's not a requirement that the reference dentry be of the same
+ filesystem type as fs_type.
(*) struct fs_context *vfs_dup_fs_context(struct fs_context *src_fc);
For the remaining operations, if an error occurs, a negative error code will be
returned.
- (*) int vfs_get_tree(struct fs_context *fc);
-
- Get or create the mountable root and superblock, using the parameters in
- the filesystem context to select/configure the superblock. This invokes
- the ->validate() op and then the ->get_tree() op.
-
- [NOTE] ->validate() could perhaps be rolled into ->get_tree() and
- ->reconfigure().
-
- (*) struct vfsmount *vfs_create_mount(struct fs_context *fc);
-
- Create a mount given the parameters in the specified filesystem context.
- Note that this does not attach the mount to anything.
-
(*) int vfs_parse_fs_param(struct fs_context *fc,
struct fs_parameter *param);
clear the pointer, but then becomes responsible for disposing of the
object.
- (*) int vfs_parse_fs_string(struct fs_context *fc, char *key,
+ (*) int vfs_parse_fs_string(struct fs_context *fc, const char *key,
const char *value, size_t v_size);
- A wrapper around vfs_parse_fs_param() that just passes a constant string.
+ A wrapper around vfs_parse_fs_param() that copies the value string it is
+ passed.
(*) int generic_parse_monolithic(struct fs_context *fc, void *data);
Parse a sys_mount() data page, assuming the form to be a text list
consisting of key[=val] options separated by commas. Each item in the
list is passed to vfs_mount_option(). This is the default when the
- ->parse_monolithic() operation is NULL.
+ ->parse_monolithic() method is NULL.
+
+ (*) int vfs_get_tree(struct fs_context *fc);
+
+ Get or create the mountable root and superblock, using the parameters in
+ the filesystem context to select/configure the superblock. This invokes
+ the ->get_tree() method.
+
+ (*) struct vfsmount *vfs_create_mount(struct fs_context *fc);
+
+ Create a mount given the parameters in the specified filesystem context.
+ Note that this does not attach the mount to anything.
+
+
+===========================
+SUPERBLOCK CREATION HELPERS
+===========================
+
+A number of VFS helpers are available for use by filesystems for the creation
+or looking up of superblocks.
+
+ (*) struct super_block *
+ sget_fc(struct fs_context *fc,
+ int (*test)(struct super_block *sb, struct fs_context *fc),
+ int (*set)(struct super_block *sb, struct fs_context *fc));
+
+ This is the core routine. If test is non-NULL, it searches for an
+ existing superblock matching the criteria held in the fs_context, using
+ the test function to match them. If no match is found, a new superblock
+ is created and the set function is called to set it up.
+
+ Prior to the set function being called, fc->s_fs_info will be transferred
+ to sb->s_fs_info - and fc->s_fs_info will be cleared if set returns
+ success (ie. 0).
+
+The following helpers all wrap sget_fc():
+
+ (*) int vfs_get_super(struct fs_context *fc,
+ enum vfs_get_super_keying keying,
+ int (*fill_super)(struct super_block *sb,
+ struct fs_context *fc))
+
+ This creates/looks up a deviceless superblock. The keying indicates how
+ many superblocks of this type may exist and in what manner they may be
+ shared:
+
+ (1) vfs_get_single_super
+
+ Only one such superblock may exist in the system. Any further
+ attempt to get a new superblock gets this one (and any parameter
+ differences are ignored).
+
+ (2) vfs_get_keyed_super
+
+ Multiple superblocks of this type may exist and they're keyed on
+ their s_fs_info pointer (for example this may refer to a
+ namespace).
+
+ (3) vfs_get_independent_super
+
+ Multiple independent superblocks of this type may exist. This
+ function never matches an existing one and always creates a new
+ one.

+BPF flow dissector is an attempt to reimplement C-based flow dissector logic
+in BPF to gain all the benefits of BPF verifier (namely, limits on the
+number of instructions and tail calls).
+
+API
+===
+
+BPF flow dissector programs operate on an ``__sk_buff``. However, only the
+limited set of fields is allowed: ``data``, ``data_end`` and ``flow_keys``.
+``flow_keys`` is ``struct bpf_flow_keys`` and contains flow dissector input
+and output arguments.
+
+The inputs are:
+ * ``nhoff`` - initial offset of the networking header
+ * ``thoff`` - initial offset of the transport header, initialized to nhoff
+ * ``n_proto`` - L3 protocol type, parsed out of L2 header
+
+Flow dissector BPF program should fill out the rest of the ``struct
+bpf_flow_keys`` fields. Input arguments ``nhoff/thoff/n_proto`` should be
+also adjusted accordingly.
+
+The return code of the BPF program is either BPF_OK to indicate successful
+dissection, or BPF_DROP to indicate parsing error.
+
+__sk_buff->data
+===============
+
+In the VLAN-less case, this is what the initial state of the BPF flow
+dissector looks like::
+
+ +------+------+------------+-----------+
+ | DMAC | SMAC | ETHER_TYPE | L3_HEADER |
+ +------+------+------------+-----------+
+ ^
+ |
+ +-- flow dissector starts here
+
+
+.. code:: c
+
+ skb->data + flow_keys->nhoff point to the first byte of L3_HEADER
+ flow_keys->thoff = nhoff
+ flow_keys->n_proto = ETHER_TYPE
+
+In case of VLAN, flow dissector can be called with the two different states.
+
+Pre-VLAN parsing::
+
+ +------+------+------+-----+-----------+-----------+
+ | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+ +------+------+------+-----+-----------+-----------+
+ ^
+ |
+ +-- flow dissector starts here
+
+.. code:: c
+
+ skb->data + flow_keys->nhoff point the to first byte of TCI
+ flow_keys->thoff = nhoff
+ flow_keys->n_proto = TPID
+
+Please note that TPID can be 802.1AD and, hence, BPF program would
+have to parse VLAN information twice for double tagged packets.
+
+
+Post-VLAN parsing::
+
+ +------+------+------+-----+-----------+-----------+
+ | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+ +------+------+------+-----+-----------+-----------+
+ ^
+ |
+ +-- flow dissector starts here
+
+.. code:: c
+
+ skb->data + flow_keys->nhoff point the to first byte of L3_HEADER
+ flow_keys->thoff = nhoff
+ flow_keys->n_proto = ETHER_TYPE
+
+In this case VLAN information has been processed before the flow dissector
+and BPF flow dissector is not required to handle it.
+
+
+The takeaway here is as follows: BPF flow dissector program can be called with
+the optional VLAN header and should gracefully handle both cases: when single
+or double VLAN is present and when it is not present. The same program
+can be called for both cases and would have to be written carefully to
+handle both cases.
+
+
+Reference Implementation
+========================
+
+See ``tools/testing/selftests/bpf/progs/bpf_flow.c`` for the reference
+implementation and ``tools/testing/selftests/bpf/flow_dissector_load.[hc]``
+for the loader. bpftool can be used to load BPF flow dissector program as well.
+
+The reference implementation is organized as follows:
+ * ``jmp_table`` map that contains sub-programs for each supported L3 protocol
+ * ``_dissect`` routine - entry point; it does input ``n_proto`` parsing and
+ does ``bpf_tail_call`` to the appropriate L3 handler
+
+Since BPF at this point doesn't support looping (or any jumping back),
+jmp_table is used instead to handle multiple levels of encapsulation (and
+IPv6 options).
+
+
+Current Limitations
+===================
+BPF flow dissector doesn't support exporting all the metadata that in-kernel
+C-based implementation can export. Notable example is single VLAN (802.1Q)
+and double VLAN (802.1AD) tags. Please refer to the ``struct bpf_flow_keys``
+for a set of information that's currently can be exported from the BPF context.

TCP Fast Path
-============
+=============
When kernel receives a TCP packet, it has two paths to handler the
packet, one is fast path, another is slow path. The comment in kernel
code provides a good explanation of them, I pasted them below::
DSACK to the sender.
* TcpExtTCPDSACKRecv
+
The TCP stack receives a DSACK, which indicates an acknowledged
duplicate packet is received.
duplicate packet is received.
invalid SACK and DSACK
-====================
+======================
When a SACK (or DSACK) block is invalid, a corresponding counter would
be updated. The validation method is base on the start/end sequence
number of the SACK block. For more details, please refer the comment
.. _Add counters for discarded SACK blocks: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=18f02545a9a16c9a89778b91a162ad16d510bb32
* TcpExtTCPSACKDiscard
+
This counter indicates how many SACK blocks are invalid. If the invalid
SACK block is caused by ACK recording, the TCP stack will only ignore
it and won't update this counter.
* TcpExtTCPDSACKIgnoredOld and TcpExtTCPDSACKIgnoredNoUndo
+
When a DSACK block is invalid, one of these two counters would be
updated. Which counter will be updated depends on the undo_marker flag
of the TCP socket. If the undo_marker is not set, the TCP stack isn't
will be updated. As implied in its name, it might be an old packet.
SACK shift
-=========
+==========
The linux networking stack stores data in sk_buff struct (skb for
short). If a SACK block acrosses multiple skb, the TCP stack will try
to re-arrange data in these skb. E.g. if a SACK block acknowledges seq
discard, this operation is 'merge'.
* TcpExtTCPSackShifted
+
A skb is shifted
* TcpExtTCPSackMerged
+
A skb is merged
* TcpExtTCPSackShiftFallback
+
A skb should be shifted or merged, but the TCP stack doesn't do it for
some reasons.

The kvm API is a set of ioctls that are issued to control various aspects
-of a virtual machine. The ioctls belong to three classes
+of a virtual machine. The ioctls belong to three classes:
- System ioctls: These query and set global attributes which affect the
whole kvm subsystem. In addition a system ioctl is used to create
- virtual machines

- VM ioctls: These query and set attributes that affect an entire virtual
machine, for example memory layout. In addition a VM ioctl is used to

- Only run VM ioctls from the same process (address space) that was used
- to create the VM.
+ VM ioctls must be issued from the same process (address space) that was

- vcpu ioctls: These query and set attributes that control the operation

- vcpu.
+ vcpu ioctls should be issued from the same thread that was used to create

2. File descriptors
-------------------
open("/dev/kvm") obtains a handle to the kvm subsystem; this handle
can be used to issue system ioctls. A KVM_CREATE_VM ioctl on this
handle will create a VM file descriptor which can be used to issue VM
-ioctls. A KVM_CREATE_VCPU ioctl on a VM fd will create a virtual cpu
-and return a file descriptor pointing to it. Finally, ioctls on a vcpu
-fd can be used to control the vcpu, including the important task of
-actually running guest code.
+ioctls. A KVM_CREATE_VCPU or KVM_CREATE_DEVICE ioctl on a VM fd will
+create a virtual cpu or device and return a file descriptor pointing to
+the new resource. Finally, ioctls on a vcpu or device fd can be used
+to control the vcpu or device. For vcpus, this includes the important
+task of actually running guest code.
In general file descriptors can be migrated among processes by means
of fork() and the SCM_RIGHTS facility of unix domain socket. These
kinds of tricks are explicitly not supported by kvm. While they will
not cause harm to the host, their actual behavior is not guaranteed by
-the API. The only supported use is one virtual machine per process,
-and one vcpu per thread.
+the API. See "General description" for details on the ioctl usage
+model that is supported by KVM.
+
+It is important to note that althought VM ioctls may only be issued from
+the process that created the VM, a VM's lifecycle is associated with its
+file descriptor, not its creator (process). In other words, the VM and
+its resources, *including the associated address space*, are not freed
+until the last reference to the VM's file descriptor has been released.
+For example, if fork() is issued after ioctl(KVM_CREATE_VM), the VM will
+not be freed until both the parent (original) process and its child have
+put their references to the VM's file descriptor.
+
+Because a VM's resources are not freed until the last reference to its
+file descriptor is released, creating additional references to a VM via
+via fork(), dup(), etc... without careful consideration is strongly
+discouraged and may have unwanted side effects, e.g. memory allocated
+by and on behalf of the VM's process may not be freed/unaccounted when
+the VM is shut down.
It is important to note that althought VM ioctls may only be issued from

- "mediatek,mt7623-gsw"
-- reg: Address and length of the register set for the device
-- interrupts: Should contain the gigabit switches interrupt
-
-
-Additional required properties for ARM based SoCs:
-- mediatek,reset-pin: phandle describing the reset GPIO
-- clocks: the clocks used by the switch
-- clock-names: the names of the clocks listed in the clocks property
- these should be "trgpll", "esw", "gp2", "gp1"
-- mt7530-supply: the phandle of the regulator used to power the switch
-- mediatek,pctl-regmap: phandle to the port control regmap. this is used to
- setup the drive current
-
-
-Optional properties:
-- interrupt-parent: Should be the phandle for the interrupt controller
- that services interrupts for this device
-
-Example:
-
-gsw: switch@1b100000 {
- compatible = "mediatek,mt7623-gsw";
- reg = <0 0x1b110000 0 0x300000>;
-
- interrupt-parent = <&pio>;
- interrupts = <168 IRQ_TYPE_EDGE_RISING>;
-
- clocks = <&apmixedsys CLK_APMIXED_TRGPLL>,
- <ðsys CLK_ETHSYS_ESW>,
- <ðsys CLK_ETHSYS_GP2>,
- <ðsys CLK_ETHSYS_GP1>;
- clock-names = "trgpll", "esw", "gp2", "gp1";
-
- mt7530-supply = <&mt6323_vpa_reg>;
-
- mediatek,pctl-regmap = <&syscfg_pctl_a>;
- mediatek,reset-pin = <&pio 15 0>;

+ * int bpf_spin_lock(struct bpf_spin_lock *lock)
+ * Description
+ * Acquire a spinlock represented by the pointer *lock*, which is
+ * stored as part of a value of a map. Taking the lock allows to
+ * safely update the rest of the fields in that value. The
+ * spinlock can (and must) later be released with a call to
+ * **bpf_spin_unlock**\ (\ *lock*\ ).
+ *
+ * Spinlocks in BPF programs come with a number of restrictions
+ * and constraints:
+ *
+ * * **bpf_spin_lock** objects are only allowed inside maps of
+ * types **BPF_MAP_TYPE_HASH** and **BPF_MAP_TYPE_ARRAY** (this
+ * list could be extended in the future).
+ * * BTF description of the map is mandatory.
+ * * The BPF program can take ONE lock at a time, since taking two
+ * or more could cause dead locks.
+ * * Only one **struct bpf_spin_lock** is allowed per map element.
+ * * When the lock is taken, calls (either BPF to BPF or helpers)
+ * are not allowed.
+ * * The **BPF_LD_ABS** and **BPF_LD_IND** instructions are not
+ * allowed inside a spinlock-ed region.
+ * * The BPF program MUST call **bpf_spin_unlock**\ () to release
+ * the lock, on all execution paths, before it returns.
+ * * The BPF program can access **struct bpf_spin_lock** only via
+ * the **bpf_spin_lock**\ () and **bpf_spin_unlock**\ ()
+ * helpers. Loading or storing data into the **struct
+ * bpf_spin_lock** *lock*\ **;** field of a map is not allowed.
+ * * To use the **bpf_spin_lock**\ () helper, the BTF description
+ * of the map value must be a struct and have **struct
+ * bpf_spin_lock** *anyname*\ **;** field at the top level.
+ * Nested lock inside another struct is not allowed.
+ * * The **struct bpf_spin_lock** *lock* field in a map value must
+ * be aligned on a multiple of 4 bytes in that value.
+ * * Syscall with command **BPF_MAP_LOOKUP_ELEM** does not copy
+ * the **bpf_spin_lock** field to user space.
+ * * Syscall with command **BPF_MAP_UPDATE_ELEM**, or update from
+ * a BPF program, do not update the **bpf_spin_lock** field.
+ * * **bpf_spin_lock** cannot be on the stack or inside a
+ * networking packet (it can only be inside of a map values).
+ * * **bpf_spin_lock** is available to root only.
+ * * Tracing programs and socket filter programs cannot use
+ * **bpf_spin_lock**\ () due to insufficient preemption checks
+ * (but this may change in the future).
+ * * **bpf_spin_lock** is not allowed in inner maps of map-in-map.
+ * Return
+ * 0
+ *
+ * int bpf_spin_unlock(struct bpf_spin_lock *lock)
+ * Description
+ * Release the *lock* previously locked by a call to
+ * **bpf_spin_lock**\ (\ *lock*\ ).
+ * Return
+ * 0
+ *
* struct bpf_sock *bpf_sk_fullsock(struct bpf_sock *sk)
* Description
* This helper gets a **struct bpf_sock** pointer such
- * that all the fields in bpf_sock can be accessed.
+ * that all the fields in this **bpf_sock** can be accessed.
* Return
- * A **struct bpf_sock** pointer on success, or NULL in
+ * A **struct bpf_sock** pointer on success, or **NULL** in
* case of failure.
*
* struct bpf_tcp_sock *bpf_tcp_sock(struct bpf_sock *sk)
* Description
* This helper gets a **struct bpf_tcp_sock** pointer from a
* **struct bpf_sock** pointer.
- *
* Return
- * A **struct bpf_tcp_sock** pointer on success, or NULL in
+ * A **struct bpf_tcp_sock** pointer on success, or **NULL** in
* case of failure.
*
* int bpf_skb_ecn_set_ce(struct sk_buf *skb)
- * Description
- * Sets ECN of IP header to ce (congestion encountered) if
- * current value is ect (ECN capable). Works with IPv6 and IPv4.
- * Return
- * 1 if set, 0 if not set.
+ * Description
+ * Set ECN (Explicit Congestion Notification) field of IP header
+ * to **CE** (Congestion Encountered) if current value is **ECT**
+ * (ECN Capable Transport). Otherwise, do nothing. Works with IPv6
+ * and IPv4.
+ * Return
+ * 1 if the **CE** flag is set (either by the current helper call
+ * or because it was already present), 0 if it is not set.
+ *
+ * struct bpf_sock *bpf_get_listener_sock(struct bpf_sock *sk)
+ * Description
+ * Return a **struct bpf_sock** pointer in **TCP_LISTEN** state.
+ * **bpf_sk_release**\ () is unnecessary and not allowed.

+ * int bpf_spin_lock(struct bpf_spin_lock *lock)
+ * Description
+ * Acquire a spinlock represented by the pointer *lock*, which is
+ * stored as part of a value of a map. Taking the lock allows to
+ * safely update the rest of the fields in that value. The
+ * spinlock can (and must) later be released with a call to
+ * **bpf_spin_unlock**\ (\ *lock*\ ).
+ *
+ * Spinlocks in BPF programs come with a number of restrictions
+ * and constraints:
+ *
+ * * **bpf_spin_lock** objects are only allowed inside maps of
+ * types **BPF_MAP_TYPE_HASH** and **BPF_MAP_TYPE_ARRAY** (this
+ * list could be extended in the future).
+ * * BTF description of the map is mandatory.
+ * * The BPF program can take ONE lock at a time, since taking two
+ * or more could cause dead locks.
+ * * Only one **struct bpf_spin_lock** is allowed per map element.
+ * * When the lock is taken, calls (either BPF to BPF or helpers)
+ * are not allowed.
+ * * The **BPF_LD_ABS** and **BPF_LD_IND** instructions are not
+ * allowed inside a spinlock-ed region.
+ * * The BPF program MUST call **bpf_spin_unlock**\ () to release
+ * the lock, on all execution paths, before it returns.
+ * * The BPF program can access **struct bpf_spin_lock** only via
+ * the **bpf_spin_lock**\ () and **bpf_spin_unlock**\ ()
+ * helpers. Loading or storing data into the **struct
+ * bpf_spin_lock** *lock*\ **;** field of a map is not allowed.
+ * * To use the **bpf_spin_lock**\ () helper, the BTF description
+ * of the map value must be a struct and have **struct
+ * bpf_spin_lock** *anyname*\ **;** field at the top level.
+ * Nested lock inside another struct is not allowed.
+ * * The **struct bpf_spin_lock** *lock* field in a map value must
+ * be aligned on a multiple of 4 bytes in that value.
+ * * Syscall with command **BPF_MAP_LOOKUP_ELEM** does not copy
+ * the **bpf_spin_lock** field to user space.
+ * * Syscall with command **BPF_MAP_UPDATE_ELEM**, or update from
+ * a BPF program, do not update the **bpf_spin_lock** field.
+ * * **bpf_spin_lock** cannot be on the stack or inside a
+ * networking packet (it can only be inside of a map values).
+ * * **bpf_spin_lock** is available to root only.
+ * * Tracing programs and socket filter programs cannot use
+ * **bpf_spin_lock**\ () due to insufficient preemption checks
+ * (but this may change in the future).
+ * * **bpf_spin_lock** is not allowed in inner maps of map-in-map.
+ * Return
+ * 0
+ *
+ * int bpf_spin_unlock(struct bpf_spin_lock *lock)
+ * Description
+ * Release the *lock* previously locked by a call to
+ * **bpf_spin_lock**\ (\ *lock*\ ).
+ * Return
+ * 0
+ *
* struct bpf_sock *bpf_sk_fullsock(struct bpf_sock *sk)
* Description
* This helper gets a **struct bpf_sock** pointer such
- * that all the fields in bpf_sock can be accessed.
+ * that all the fields in this **bpf_sock** can be accessed.
* Return
- * A **struct bpf_sock** pointer on success, or NULL in
+ * A **struct bpf_sock** pointer on success, or **NULL** in
* case of failure.
*
* struct bpf_tcp_sock *bpf_tcp_sock(struct bpf_sock *sk)
* Description
* This helper gets a **struct bpf_tcp_sock** pointer from a
* **struct bpf_sock** pointer.
- *
* Return
- * A **struct bpf_tcp_sock** pointer on success, or NULL in
+ * A **struct bpf_tcp_sock** pointer on success, or **NULL** in
* case of failure.
*
* int bpf_skb_ecn_set_ce(struct sk_buf *skb)
- * Description
- * Sets ECN of IP header to ce (congestion encountered) if
- * current value is ect (ECN capable). Works with IPv6 and IPv4.
- * Return
- * 1 if set, 0 if not set.
+ * Description
+ * Set ECN (Explicit Congestion Notification) field of IP header
+ * to **CE** (Congestion Encountered) if current value is **ECT**
+ * (ECN Capable Transport). Otherwise, do nothing. Works with IPv6
+ * and IPv4.
+ * Return
+ * 1 if the **CE** flag is set (either by the current helper call
+ * or because it was already present), 0 if it is not set.
+ *
+ * struct bpf_sock *bpf_get_listener_sock(struct bpf_sock *sk)
+ * Description
+ * Return a **struct bpf_sock** pointer in **TCP_LISTEN** state.
+ * **bpf_sk_release**\ () is unnecessary and not allowed.
