First set of new device support, fixes, cleanups and features for IIO in 5.18
This cycle we had quite a few series that applied similar changes
to lots of drivers. To keep this description manageable I have
called those out in their own section rather than per driver.
Particularly pleased to see the long running AFE precision series
going in this cycle.
Series includes some late breaking fixes.
New device support
* adi,ada4250 amplifier
- New driver and dt bindings for this programmable gain amplifier.
* adi,admv1014 microwave down-converter
- New driver, dt bindings and some device specific ABI that
may be generalized as more drivers for devices similar to this
are added.
* adi,admv4420 K Band down-converter.
- New driver and dt bindings.
* adi,adxl367 accelerometer driver.
- New driver, dt-bindings + some new IIO ABI definitions to support
reference magnitude events where an estimate of the acceleration
due to gravity has been removed.
- A few fixes as follow up patches.
* adi,ltc2688 DAC with toggle and dither modes.
- New driver and bindings. Includes some new driver specific (for now)
ABI for handling toggle mode and the addition of a dither waveform to
the DAC output.
* AFE (analog front end) add support for additional types of analog device
in front of an ADC.
- RTD temperature sensors with dt bindings.
- Temperature transducers wit dt bindings.
- Related cleanup and features listed in other sections below.
* maxim,ds3502 potentiometer.
- Add support to ds1803 driver which required significant rework.
* mediatek,mt2701-auxadc driver
- Add mediatek,mt8186-auxadc - id table and chip specific info only.
* semtech,sx9324, semtech,ax9360
- Substantial refactoring of sx9310 to extract core logic for reuse
into a separate module
- New driver using this supporting sx9324 proximity sensors.
- New driver using this supporting sx9360 proximity sensors.
* silan,sc7a20
- Compatible with the st,lis2dh (or nearly anyway) so add ID and
chip specific info to enable support. Also silan vendor ID added
for dt-bindings.
Staging graduation
* adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
electric cars and similar.
- Substantial rework of driver required to bring inline with current
IIO best practice. An unusual device in IIO so some interesting features
we may see more of in future.
Multiple driver/core cleanup
- Use sysfs_emit() in simple locations where there is no path to change
to various core created attributes.
- Trivial white space fixes around inconsistency between space after { and
before } in id tables.
- Introduce new handling for fractional types to avoid repeated similar
implementations. Use this in 3 drivers. Note this is also targeted
at future use in the AFE driver and was motivated by discussions
around the precision related work on that driver.
- of related header cleanups - drop of*.h and add mod_devicetable.h as
appropriate.
- Move a number of symbol exports into IIO_* namespaces. Two categories,
1) Library used by multiple drivers e.g. st_sensors
2) Core driver module exporting functions used by bus specific modules.
A few related cleanups in this set.
- Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
similar to simplify drivers and take advantage of these new macros
allowing the compiler to do the job or removing unused code without
the need for __maybe_unused markings. Conversion of other drivers to
these new macros ongoing.
Features
* adi,adf4350
- Switch from of specific to generic device properties enabling use with
other firmware types.

Again new complaints surfaced that we had broken the ABI here,
although previously all the userspace tools had agreed that it
was their mistake and fixed it. Yet now there are cases (e.g.
RHEL) that want to run old userspace with newer kernels, and
thus are broken.
Since this is a bit of a whack-a-mole thing, change the whole
extensibility scheme of rfkill to no longer just rely on the
message lengths, but instead require userspace to opt in via a
new ioctl to a given maximum event size that it is willing to
understand.
By default, set that to RFKILL_EVENT_SIZE_V1 (8), so that the
behaviour for userspace not calling the ioctl will look as if
it's just running on an older kernel.

Adding support to call bpf_get_attach_cookie helper from
kprobe programs attached with kprobe multi link.
The cookie is provided by array of u64 values, where each
value is paired with provided function address or symbol
with the same array index.
When cookie array is provided it's sorted together with
addresses (check bpf_kprobe_multi_cookie_swap). This way
we can find cookie based on the address in
bpf_get_attach_cookie helper.

Adding new link type BPF_LINK_TYPE_KPROBE_MULTI that attaches kprobe
program through fprobe API.
The fprobe API allows to attach probe on multiple functions at once
very fast, because it works on top of ftrace. On the other hand this
limits the probe point to the function entry or return.
The kprobe program gets the same pt_regs input ctx as when it's attached
through the perf API.
Adding new attach type BPF_TRACE_KPROBE_MULTI that allows attachment
kprobe to multiple function with new link.
User provides array of addresses or symbols with count to attach the
kprobe program to. The new link_create uapi interface looks like:
struct {
__u32 flags;
__u32 cnt;
__aligned_u64 syms;
__aligned_u64 addrs;
} kprobe_multi;
The flags field allows single BPF_TRACE_KPROBE_MULTI bit to create
return multi kprobe.

Make it possible to change the port state in a given MSTI by extending
the bridge port netlink interface (RTM_SETLINK on PF_BRIDGE).The
proposed iproute2 interface would be:
bridge mst set dev <PORT> msti <MSTI> state <STATE>
Current states in all applicable MSTIs can also be dumped via a
corresponding RTM_GETLINK. The proposed iproute interface looks like
this:
$ bridge mst
port msti
vb1 0
state forwarding
100
state disabled
vb2 0
state forwarding
100
state forwarding
The preexisting per-VLAN states are still valid in the MST
mode (although they are read-only), and can be queried as usual if one
is interested in knowing a particular VLAN's state without having to
care about the VID to MSTI mapping (in this example VLAN 20 and 30 are
bound to MSTI 100):
$ bridge -d vlan
port vlan-id
vb1 10
state forwarding mcast_router 1
20
state disabled mcast_router 1
30
state disabled mcast_router 1
40
state forwarding mcast_router 1
vb2 10
state forwarding mcast_router 1
20
state forwarding mcast_router 1
30
state forwarding mcast_router 1
40
state forwarding mcast_router 1

Allow a VLAN to move out of the CST (MSTI 0), to an independent tree.
The user manages the VID to MSTI mappings via a global VLAN
setting. The proposed iproute2 interface would be:
bridge vlan global set dev br0 vid <VID> msti <MSTI>
Changing the state in non-zero MSTIs is still not supported, but will
be addressed in upcoming changes.

Allow the user to switch from the current per-VLAN STP mode to an MST
mode.
Up to this point, per-VLAN STP states where always isolated from each
other. This is in contrast to the MSTP standard (802.1Q-2018, Clause
13.5), where VLANs are grouped into MST instances (MSTIs), and the
state is managed on a per-MSTI level, rather that at the per-VLAN
level.
Perhaps due to the prevalence of the standard, many switching ASICs
are built after the same model. Therefore, add a corresponding MST
mode to the bridge, which we can later add offloading support for in a
straight-forward way.
For now, all VLANs are fixed to MSTI 0, also called the Common
Spanning Tree (CST). That is, all VLANs will follow the port-global
state.
Upcoming changes will make this actually useful by allowing VLANs to
be mapped to arbitrary MSTIs and allow individual MSTI states to be
changed.

This patch adds support for encapsulating IPv4/IPv6 within GENEVE.
In order to use this, a new IFLA_GENEVE_INNER_PROTO_INHERIT flag needs
to be provided at device creation. This property cannot be changed for

In case IP traffic is received on a non-tun device the drop count is
increased.

Allow the user space application to create and release an rpmsg device
by adding RPMSG_CREATE_DEV_IOCTL and RPMSG_RELEASE_DEV_IOCTL ioctrls to
the /dev/rpmsg_ctrl interface
The RPMSG_CREATE_DEV_IOCTL Ioctl can be used to instantiate a local rpmsg
device.
Depending on the back-end implementation, the associated rpmsg driver is
probed and a NS announcement can be sent to the remote processor.
The RPMSG_RELEASE_DEV_IOCTL allows the user application to release a
rpmsg device created either by the remote processor or with the
RPMSG_CREATE_DEV_IOCTL call.
Depending on the back-end implementation, the associated rpmsg driver is
removed and a NS destroy rpmsg can be sent to the remote processor.

ice: GTP support in switchdev
Marcin Szycik says:
Add support for adding GTP-C and GTP-U filters in switchdev mode.
To create a filter for GTP, create a GTP-type netdev with ip tool, enable
hardware offload, add qdisc and add a filter in tc:
ip link add $GTP0 type gtp role <sgsn/ggsn> hsize <hsize>
ethtool -K $PF0 hw-tc-offload on
tc qdisc add dev $GTP0 ingress
tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \
action mirred egress redirect dev $VF1_PR
By default, a filter for GTP-U will be added. To add a filter for GTP-C,
specify enc_dst_port = 2123, e.g.:
tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \
enc_dst_port 2123 action mirred egress redirect dev $VF1_PR
Note: outer IPv6 offload is not supported yet.
Note: GTP-U with no payload offload is not supported yet.
ICE COMMS package is required to create a filter as it contains GTP
profiles.
Changes in iproute2 [1] are required to be able to add GTP netdev and use
GTP-specific options (QFI and PDU type).

Adding GTP device through ip link creates the situation where
GTP instance is not able to send GTP echo requests.
Echo requests are used to check if GTP peer is still alive.
With this patch, gtp_genl_ops are extended by new cmd (GTP_CMD_ECHOREQ)
which allows to send echo request in the given version of GTP
protocol (v0 or v1), from the given ms address to he given
peer. TID is not inclued because in all path management
messages it should be equal to 0.
When GTP echo response is detected, multicast message is
send to everyone in the gtp_genl_family. Message contains
GTP version, ms address and peer address.

Adding GTP device through ip link creates the situation where
there is no userspace daemon which would handle GTP messages
(Echo Request for example). GTP-U instance which would not respond

When GTP packet arrives with GTP_ECHO_REQ message type,
GTP_ECHO_RSP is send to the sender. GTP_ECHO_RSP message
should contain information element with GTPIE_RECOVERY tag and
restart counter value. For GTPv1 restart counter is not used
and should be equal to 0, for GTPv0 restart counter contains

Currently, when the user wants to create GTP device, he has to
provide file handles to the sockets created in userspace (IFLA_GTP_FD0,
IFLA_GTP_FD1). This behaviour is not ideal, considering the option of
adding support for GTP device creation through ip link. Ip link
application is not a good place to create such sockets.
This patch allows to create GTP device without providing
IFLA_GTP_FD0 and IFLA_GTP_FD1 arguments. If the user sets
IFLA_GTP_CREATE_SOCKETS attribute, then GTP module takes care
of creating UDP sockets by itself. Sockets are created with the
commonly known UDP ports used for GTP protocol (GTP0_PORT and
GTP1U_PORT). In this case we don't have to provide encap_destroy
because no extra deinitialization is needed, everything is covered
by udp_tunnel_sock_release.
Note: GTP instance created with only this change applied, does
not handle GTP Echo Requests. This is implemented in the following
patch.

Few years ago OVS user space made a strange choice in the commit [1]
to define types only valid for the user space inside the copy of a
kernel uAPI header. '#ifndef __KERNEL__' and another attribute was
added later.
This leads to the inevitable clash between user space and kernel types
when the kernel uAPI is extended. The issue was unveiled with the
addition of a new type for IPv6 extension header in kernel uAPI.
When kernel provides the OVS_KEY_ATTR_IPV6_EXTHDRS attribute to the
older user space application, application tries to parse it as
OVS_KEY_ATTR_PACKET_TYPE and discards the whole netlink message as
malformed. Since OVS_KEY_ATTR_IPV6_EXTHDRS is supplied along with
every IPv6 packet that goes to the user space, IPv6 support is fully
broken.
Fixing that by bringing these user space attributes to the kernel
uAPI to avoid the clash. Strictly speaking this is not the problem
of the kernel uAPI, but changing it is the only way to avoid breakage
of the older user space applications at this point.
These 2 types are explicitly rejected now since they should not be
passed to the kernel. Additionally, OVS_KEY_ATTR_TUNNEL_INFO moved
out from the '#ifdef __KERNEL__' as there is no good reason to hide
it from the userspace. And it's also explicitly rejected now, because
it's for in-kernel use only.
Comments with warnings were added to avoid the problem coming back.
(1 << type) converted to (1ULL << type) to avoid integer overflow on
OVS_KEY_ATTR_IPV6_EXTHDRS, since it equals 32 now.

This patch is to simplify the uapi bpf.h regarding to the tstamp type
and use a similar way as the kernel to describe the value stored
in __sk_buff->tstamp.
My earlier thought was to avoid describing the semantic and
clock base for the rcv timestamp until there is more clarity
on the use case, so the __sk_buff->delivery_time_type naming instead
of __sk_buff->tstamp_type.
With some thoughts, it can reuse the UNSPEC naming. This patch first
removes BPF_SKB_DELIVERY_TIME_NONE and also
rename BPF_SKB_DELIVERY_TIME_UNSPEC to BPF_SKB_TSTAMP_UNSPEC
and BPF_SKB_DELIVERY_TIME_MONO to BPF_SKB_TSTAMP_DELIVERY_MONO.
The semantic of BPF_SKB_TSTAMP_DELIVERY_MONO is the same:
__sk_buff->tstamp has delivery time in mono clock base.
BPF_SKB_TSTAMP_UNSPEC means __sk_buff->tstamp has the (rcv)
tstamp at ingress and the delivery time at egress. At egress,
the clock base could be found from skb->sk->sk_clockid.
__sk_buff->tstamp == 0 naturally means NONE, so NONE is not needed.
With BPF_SKB_TSTAMP_UNSPEC for the rcv tstamp at ingress,
the __sk_buff->delivery_time_type is also renamed to __sk_buff->tstamp_type
which was also suggested in the earlier discussion:
https://lore.kernel.org/bpf/b181acbe-caf8-502d-4b7b-7d96b9fc5d55@iogearbox.net/
The above will then make __sk_buff->tstamp and __sk_buff->tstamp_type
the same as its kernel skb->tstamp and skb->mono_delivery_time
counter part.
The internal kernel function bpf_skb_convert_dtime_type_read() is then
renamed to bpf_skb_convert_tstamp_type_read() and it can be simplified
with the BPF_SKB_DELIVERY_TIME_NONE gone. A BPF_ALU32_IMM(BPF_AND)
insn is also saved by using BPF_JMP32_IMM(BPF_JSET).
The bpf helper bpf_skb_set_delivery_time() is also renamed to
bpf_skb_set_tstamp(). The arg name is changed from dtime
to tstamp also. It only allows setting tstamp 0 for
BPF_SKB_TSTAMP_UNSPEC and it could be relaxed later
if there is use case to change mono delivery time to
non mono.
prog->delivery_time_access is also renamed to prog->tstamp_type_access.

By default, io_uring will stop submitting a batch of requests if we run
into an error submitting a request. This isn't strictly necessary, as
the error result is passed out-of-band via a CQE anyway. And it can be
a bit confusing for some applications.
Provide a way to setup a ring that will continue submitting on error,
when the error CQE has been posted.
There's still one case that will break out of submission. If we fail
allocating a request, then we'll still return -ENOMEM. We could in theory
post a CQE for that condition too even if we never got a request. Leave
that for a potential followup.

This adds support for IORING_OP_MSG_RING, which allows an SQE to signal
another ring. That allows either waking up someone waiting on the ring,
or even passing a 64-bit value via the user_data field in the CQE.
sqe->fd must contain the fd of a ring that should receive the CQE.
sqe->off will be propagated to the cqe->user_data on the target ring,
and sqe->len will be propagated to cqe->res. The results CQE will have
IORING_CQE_F_MSG set in its flags, to indicate that this CQE was generated
from a messaging request rather than a SQE issued locally on that ring.
This effectively allows passing a 64-bit and a 32-bit quantify between
the two rings.
This request type has the following request specific error cases:
- -EBADFD. Set if the sqe->fd doesn't point to a file descriptor that is
of the io_uring type.
- -EOVERFLOW. Set if we were not able to deliver a request to the target
ring.

Lots of workloads use multiple threads, in which case the file table is
shared between them. This makes getting and putting the ring file
descriptor for each io_uring_enter(2) system call more expensive, as it
involves an atomic get and put for each call.
Similarly to how we allow registering normal file descriptors to avoid
this overhead, add support for an io_uring_register(2) API that allows
to register the ring fds themselves:
1) IORING_REGISTER_RING_FDS - takes an array of io_uring_rsrc_update
structs, and registers them with the task.
2) IORING_UNREGISTER_RING_FDS - takes an array of io_uring_src_update
structs, and unregisters them.
When a ring fd is registered, it is internally represented by an offset.
This offset is returned to the application, and the application then
uses this offset and sets IORING_ENTER_REGISTERED_RING for the
io_uring_enter(2) system call. This works just like using a registered
file descriptor, rather than a real one, in an SQE, where
IOSQE_FIXED_FILE gets set to tell io_uring that we're using an internal
offset/descriptor rather than a real file descriptor.
In initial testing, this provides a nice bump in performance for
threaded applications in real world cases where the batch count (eg
number of requests submitted per io_uring_enter(2) invocation) is low.
In a microbenchmark, submitting NOP requests, we see the following
increases in performance:
Requests per syscall Baseline Registered Increase

1 ~7030K ~8080K +15%
2 ~13120K ~14800K +13%

The N_As value describes the time a CAN frame needs on the wire when
transmitted by the CAN controller. Even very short CAN FD frames need
arround 100 usecs (bitrate 1Mbit/s, data bitrate 8Mbit/s).
Having N_As to be zero (the former default) leads to 'no CAN frame
separation' when STmin is set to zero by the receiving node. This 'burst
mode' should not be enabled by default as it could potentially dump a high
number of CAN frames into the netdev queue from the soft hrtimer context.
This does not affect the system stability but is just not nice and
cooperative.
With this N_As/frame_txtime value the 'burst mode' is disabled by default.
As user space applications usually do not set the frame_txtime element
of struct can_isotp_options the new in-kernel default is very likely
overwritten with zero when the sockopt() CAN_ISOTP_OPTS is invoked.
To make sure that a N_As value of zero is only set intentional the
value '0' is now interpreted as 'do not change the current value'.
When a frame_txtime of zero is required for testing purposes this
CAN_ISOTP_FRAME_TXTIME_ZERO u32 value has to be set in frame_txtime.

This adds support for running XDP programs through BPF_PROG_RUN in a mode
that enables live packet processing of the resulting frames. Previous uses
of BPF_PROG_RUN for XDP returned the XDP program return code and the
modified packet data to userspace, which is useful for unit testing of XDP
programs.
The existing BPF_PROG_RUN for XDP allows userspace to set the ingress
ifindex and RXQ number as part of the context object being passed to the
kernel. This patch reuses that code, but adds a new mode with different
semantics, which can be selected with the new BPF_F_TEST_XDP_LIVE_FRAMES
flag.
When running BPF_PROG_RUN in this mode, the XDP program return codes will
be honoured: returning XDP_PASS will result in the frame being injected
into the networking stack as if it came from the selected networking
interface, while returning XDP_TX and XDP_REDIRECT will result in the frame
being transmitted out that interface. XDP_TX is translated into an
XDP_REDIRECT operation to the same interface, since the real XDP_TX action
is only possible from within the network drivers themselves, not from the
process context where BPF_PROG_RUN is executed.
Internally, this new mode of operation creates a page pool instance while
setting up the test run, and feeds pages from that into the XDP program.
The setup cost of this is amortised over the number of repetitions
specified by userspace.
To support the performance testing use case, we further optimise the setup
step so that all pages in the pool are pre-initialised with the packet
data, and pre-computed context and xdp_frame objects stored at the start of
each page. This makes it possible to entirely avoid touching the page
content on each XDP program invocation, and enables sending up to 9
Mpps/core on my test box.
Because the data pages are recycled by the page pool, and the test runner
doesn't re-initialise them for each run, subsequent invocations of the XDP
program will see the packet data in the state it was after the last time it
ran on that particular page. This means that an XDP program that modifies
the packet before redirecting it has to be careful about which assumptions
it makes about the packet content, but that is only an issue for the most
naively written programs.
Enabling the new flag is only allowed when not setting ctx_out and data_out
in the test specification, since using it means frames will be redirected
somewhere else, so they can't be returned.

In some edge scenarios, an MPTCP subflows can use a local address
mapped by a "implicit" endpoint created by the in-kernel path manager.
Such endpoints presence can be confusing, as it's creation is hard
to track and will prevent the later endpoint creation from the user-space
using the same address.
Define a new endpoint flag to mark implicit endpoints and allow the
user-space to replace implicit them with user-provided data at endpoint
creation time.

Pull networking fixes from Jakub Kicinski:
"Including fixes from can, xfrm, wifi, bluetooth, and netfilter.
Lots of various size fixes, the length of the tag speaks for itself.
Most of the 5.17-relevant stuff comes from xfrm, wifi and bt trees
which had been lagging as you pointed out previously. But there's also
a larger than we'd like portion of fixes for bugs from previous
releases.
Three more fixes still under discussion, including and xfrm revert for
uAPI error.
Current release - regressions:
- iwlwifi: don't advertise TWT support, prevent FW crash
- xfrm: fix the if_id check in changelink
- xen/netfront: destroy queues before real_num_tx_queues is zeroed
- bluetooth: fix not checking MGMT cmd pending queue, make scanning
work again
Current release - new code bugs:
- mptcp: make SIOCOUTQ accurate for fallback socket
- bluetooth: access skb->len after null check
- bluetooth: hci_sync: fix not using conn_timeout
- smc: fix cleanup when register ULP fails
- dsa: restore error path of dsa_tree_change_tag_proto
- iwlwifi: fix build error for IWLMEI
- iwlwifi: mvm: propagate error from request_ownership to the user
Previous releases - regressions:
- xfrm: fix pMTU regression when reported pMTU is too small
- xfrm: fix TCP MSS calculation when pMTU is close to 1280
- bluetooth: fix bt_skb_sendmmsg not allocating partial chunks
- ipv6: ensure we call ipv6_mc_down() at most once, prevent leaks
- ipv6: prevent leaks in igmp6 when input queues get full
- fix up skbs delta_truesize in UDP GRO frag_list
- eth: e1000e: fix possible HW unit hang after an s0ix exit
- eth: e1000e: correct NVM checksum verification flow
- ptp: ocp: fix large time adjustments
Previous releases - always broken:
- tcp: make tcp_read_sock() more robust in presence of urgent data
- xfrm: distinguishing SAs and SPs by if_id in xfrm_migrate
- xfrm: fix xfrm_migrate issues when address family changes
- dcb: flush lingering app table entries for unregistered devices
- smc: fix unexpected SMC_CLC_DECL_ERR_REGRMB error
- mac80211: fix EAPoL rekey fail in 802.3 rx path
- mac80211: fix forwarded mesh frames AC & queue selection
- netfilter: nf_queue: fix socket access races and bugs
- batman-adv: fix ToCToU iflink problems and check the result belongs
to the expected net namespace
- can: gs_usb, etas_es58x: fix opened_channel_cnt's accounting
- can: rcar_canfd: register the CAN device when fully ready
- eth: igb, igc: phy: drop premature return leaking HW semaphore
- eth: ixgbe: xsk: change !netif_carrier_ok() handling in
ixgbe_xmit_zc(), prevent live lock when link goes down
- eth: stmmac: only enable DMA interrupts when ready
- eth: sparx5: move vlan checks before any changes are made
- eth: iavf: fix races around init, removal, resets and vlan ops
- ibmvnic: more reset flow fixes
Misc:
- eth: fix return value of __setup handlers"

* __sk_buff->delivery_time_type:
This patch adds __sk_buff->delivery_time_type. It tells if the
delivery_time is stored in __sk_buff->tstamp or not.
It will be most useful for ingress to tell if the __sk_buff->tstamp
has the (rcv) timestamp or delivery_time. If delivery_time_type
is 0 (BPF_SKB_DELIVERY_TIME_NONE), it has the (rcv) timestamp.
Two non-zero types are defined for the delivery_time_type,
BPF_SKB_DELIVERY_TIME_MONO and BPF_SKB_DELIVERY_TIME_UNSPEC. For UNSPEC,
it can only happen in egress because only mono delivery_time can be
forwarded to ingress now. The clock of UNSPEC delivery_time
can be deduced from the skb->sk->sk_clockid which is how
the sch_etf doing it also.
* Provide forwarded delivery_time to tc-bpf@ingress:
With the help of the new delivery_time_type, the tc-bpf has a way
to tell if the __sk_buff->tstamp has the (rcv) timestamp or
the delivery_time. During bpf load time, the verifier will learn if
the bpf prog has accessed the new __sk_buff->delivery_time_type.
If it does, it means the tc-bpf@ingress is expecting the
skb->tstamp could have the delivery_time. The kernel will then
read the skb->tstamp as-is during bpf insn rewrite without
checking the skb->mono_delivery_time. This is done by adding a
new prog->delivery_time_access bit. The same goes for
writing skb->tstamp.
* bpf_skb_set_delivery_time():
The bpf_skb_set_delivery_time() helper is added to allow setting both
delivery_time and the delivery_time_type at the same time. If the
tc-bpf does not need to change the delivery_time_type, it can directly
write to the __sk_buff->tstamp as the existing tc-bpf has already been
doing. It will be most useful at ingress to change the
__sk_buff->tstamp from the (rcv) timestamp to
a mono delivery_time and then bpf_redirect_*().
bpf only has mono clock helper (bpf_ktime_get_ns), and
the current known use case is the mono EDT for fq, and
only mono delivery time can be kept during forward now,
so bpf_skb_set_delivery_time() only supports setting
BPF_SKB_DELIVERY_TIME_MONO. It can be extended later when use cases
come up and the forwarding path also supports other clock bases.
