After IPv6 support has recently been added to metadata dst and related
encaps, add support for populating/reading it from an eBPF program.
Commit d3aa45ce6b ("bpf: add helpers to access tunnel metadata") started
with initial IPv4-only support back then (due to IPv6 metadata support
not being available yet).
To stay compatible with older programs, we need to test for the passed
structure size. Also TOS and TTL support from the ip_tunnel_info key has
been added. Tested with vxlan devs in collect meta data mode with IPv4,
IPv6 and in compat mode over different network namespaces.

Export flags used by eBPF helper functions through UAPI, so they can be
used by programs (instead of them redefining all flags each time or just
using the hard-coded values). It also gives a better overview what flags
are used where and we can further get rid of the extra macros defined in
filter.c. Moreover, reject invalid flags.

This work adds a generalization of the ingress qdisc as a qdisc holding
only classifiers. The clsact qdisc works on ingress, but also on egress.
In both cases, it's execution happens without taking the qdisc lock, and
the main difference for the egress part compared to prior version of [1]
is that this can be applied with _any_ underlying real egress qdisc (also
classless ones).
Besides solving the use-case of [1], that is, allowing for more programmability
on assigning skb->priority for the mqprio case that is supported by most
popular 10G+ NICs, it also opens up a lot more flexibility for other tc
applications. The main work on classification can already be done at clsact
egress time if the use-case allows and state stored for later retrieval
f.e. again in skb->priority with major/minors (which is checked by most
classful qdiscs before consulting tc_classify()) and/or in other skb fields
like skb->tc_index for some light-weight post-processing to get to the
eventual classid in case of a classful qdisc. Another use case is that
the clsact egress part allows to have a central egress counterpart to
the ingress classifiers, so that classifiers can easily share state (e.g.
in cls_bpf via eBPF maps) for ingress and egress.
Currently, default setups like mq + pfifo_fast would require for this to
use, for example, prio qdisc instead (to get a tc_classify() run) and to
duplicate the egress classifier for each queue. With clsact, it allows
for leaving the setup as is, it can additionally assign skb->priority to
put the skb in one of pfifo_fast's bands and it can share state with maps.
Moreover, we can access the skb's dst entry (f.e. to retrieve tclassid)
w/o the need to perform a skb_dst_force() to hold on to it any longer. In
lwt case, we can also use this facility to setup dst metadata via cls_bpf
(bpf_skb_set_tunnel_key()) without needing a real egress qdisc just for
that (case of IFF_NO_QUEUE devices, for example).
The realization can be done without any changes to the scheduler core
framework. All it takes is that we have two a-priori defined minors/child
classes, where we can mux between ingress and egress classifier list
(dev->ingress_cl_list and dev->egress_cl_list, latter stored close to
dev->_tx to avoid extra cacheline miss for moderate loads). The egress
part is a bit similar modelled to handle_ing() and patched to a noop in
case the functionality is not used. Both handlers are now called
sch_handle_ingress() and sch_handle_egress(), code sharing among the two
doesn't seem practical as there are various minor differences in both
paths, so that making them conditional in a single handler would rather
slow things down.
Full compatibility to ingress qdisc is provided as well. Since both
piggyback on TC_H_CLSACT, only one of them (ingress/clsact) can exist
per netdevice, and thus ingress qdisc specific behaviour can be retained
for user space. This means, either a user does 'tc qdisc add dev foo ingress'
and configures ingress qdisc as usual, or the 'tc qdisc add dev foo clsact'
alternative, where both, ingress and egress classifier can be configured
as in the below example. ingress qdisc supports attaching classifier to any
minor number whereas clsact has two fixed minors for muxing between the
lists, therefore to not break user space setups, they are better done as
two separate qdiscs.
I decided to extend the sch_ingress module with clsact functionality so
that commonly used code can be reused, the module is being aliased with
sch_clsact so that it can be auto-loaded properly. Alternative would have been
to add a flag when initializing ingress to alter its behaviour plus aliasing
to a different name (as it's more than just ingress). However, the first would
end up, based on the flag, choosing the new/old behaviour by calling different
function implementations to handle each anyway, the latter would require to
register ingress qdisc once again under different alias. So, this really begs
to provide a minimal, cleaner approach to have Qdisc_ops and Qdisc_class_ops
by its own that share callbacks used by both.
Example, adding qdisc:
# tc qdisc add dev foo clsact
# tc qdisc show dev foo
qdisc mq 0: root
qdisc pfifo_fast 0: parent :1 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :3 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :4 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc clsact ffff: parent ffff:fff1
Adding filters (deleting, etc works analogous by specifying ingress/egress):
# tc filter add dev foo ingress bpf da obj bar.o sec ingress
# tc filter add dev foo egress bpf da obj bar.o sec egress
# tc filter show dev foo ingress
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bar.o:[ingress] direct-action
# tc filter show dev foo egress
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bar.o:[egress] direct-action
A 'tc filter show dev foo' or 'tc filter show dev foo parent ffff:' will
show an empty list for clsact. Either using the parent names (ingress/egress)
or specifying the full major/minor will then show the related filter lists.
Prior work on a mqprio prequeue() facility [1] was done mainly by John Fastabend.

When hacking tc programs with eBPF, one of the issues that come up
from time to time is to load addresses from headers. In eBPF as in
classic BPF, we have BPF_LD | BPF_ABS | BPF_{B,H,W} instructions that
extract a byte, half-word or word out of the skb data though helpers
such as bpf_load_pointer() (interpreter case).
F.e. extracting a whole IPv6 address could possibly look like ...
union v6addr {
struct {
__u32 p1;
__u32 p2;
__u32 p3;
__u32 p4;
};
__u8 addr[16];
};
[...]
a.p1 = htonl(load_word(skb, off));
a.p2 = htonl(load_word(skb, off + 4));
a.p3 = htonl(load_word(skb, off + 8));
a.p4 = htonl(load_word(skb, off + 12));
[...]
/* access to a.addr[...] */
This work adds a complementary helper bpf_skb_load_bytes() (we also
have bpf_skb_store_bytes()) as an alternative where the same call
would look like from an eBPF program:
ret = bpf_skb_load_bytes(skb, off, addr, sizeof(addr));
Same verifier restrictions apply as in ffeedafbf0 ("bpf: introduce
current->pid, tgid, uid, gid, comm accessors") case, where stack memory
access needs to be statically verified and thus guaranteed to be
initialized in first use (otherwise verifier cannot tell whether a
subsequent access to it is valid or not as it's runtime dependent).

Add a new address generator mode, using the stable address generator
with an automatically generated secret. This is intended as a default
address generator mode for device types with no EUI64 implementation.
The new generator is used for ARPHRD_NONE interfaces initially, adding
default IPv6 autoconf support to e.g. tun interfaces.
If the addrgenmode is set to 'random', either by default or manually,
and no stable secret is available, then a random secret is used as
input for the stable-privacy address generator. The secret can be
read and modified like manually configured secrets, using the proc
interface. Modifying the secret will change the addrgen mode to
'stable-privacy' to indicate that it operates on a known secret.
Existing behaviour of the 'stable-privacy' mode is kept unchanged. If
a known secret is available when the device is created, then the mode
will default to 'stable-privacy' as before. The mode can be manually
set to 'random' but it will behave exactly like 'stable-privacy' in
this case. The secret will not change.

To avoid bloating nft_do_chain all data required for tracing is

Revert commit 033291eccb ("vfio: Include No-IOMMU mode") due to lack
of a user. This was originally intended to fill a need for the DPDK
driver, but uptake has been slow so rather than support an unproven
kernel interface revert it and revisit when userspace catches up.

Implement new functionality for aborting an ongoing scan.
Add NL80211_CMD_ABORT_SCAN to the nl80211 interface. After
aborting the scan, driver shall provide the scan status by
calling cfg80211_scan_done().

In this attribute's documentation, it was not clear whether the delay
started counting when WoWLAN net-detect was enabled or when the system
was suspended. The correct answer is that it starts when the system
suspends (which is when, in practice, the scan is scheduled). Clarify
that in the nl80211.h documentation.

Add support for mangling packet payload. Checksum for the specified base
header is updated automatically if requested, however no updates for any
kind of pseudo headers are supported, meaning no stateless NAT is supported.
For checksum updates different checksumming methods can be specified. The
currently supported methods are NONE for no checksum updates, and INET for
internet type checksums.

ip_ct_sctp is an internal structure, embedded by the union

This patch moves it from UAPI to a saner place, together with similar

drm: Use userspace compatible type in fourcc_mod_code macro
As we've enabled multiplatform kernels on ARM, and greatly done away with
the contents under arch/arm/mach-*, there's still need for SoC-related
drivers to go somewhere.
Many of them go in through other driver trees, but we still have
drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
that might be shared between ARM and ARM64 (or just in general makes
sense to not have under the architecture directory).
This branch contains mostly such code:
- Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
with power management blocks on these SoCs for use by clock, regulator and
bus frequency drivers.
- Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
- Drivers for ARM's SCPI (System Control Processor). Not to be confused with
PSCI (Power State Coordination Interface). SCPI is used to communicate with
the assistant embedded cores doing power management, and we have yet to see
how many of them will implement this for their hardware vs abstracting in
other ways (or not at all like in the past).
- To make confusion between SCPI and PSCI more likely, this release also
includes an update of PSCI to interface version 1.0.
- Rockchip support for power domains.
- A driver to talk to the firmware on Raspberry Pi.

"We have a lot of subvolume quota improvements in here, along with big
piles of cleanups from Dave Sterba and Anand Jain and others.
Josef pitched in a batch of allocator fixes based on production use
here at FB. We found that mount -o ssd_spread greatly improved our
performance on hardware raid5/6, but it exposed some CPU bottlenecks
in the allocator. These patches make a huge difference"

userspace utilities to change the file system's UUID without rewriting
all of the file system metadata.
A number of miscellaneous fixes, the most significant of which are in
the ext4 encryption support. Anyone wishing to use the encryption
feature should backport all of the ext4 crypto patches up to 4.4 to
get fixes to a memory leak and file system corruption bug.
There are also cleanups in ext4's feature test macros and in ext4's
sysfs support code.
