Like the previous patch, the goal is to ease to convert nsids from one
netns to another netns.
A new attribute (NETNSA_CURRENT_NSID) is added to the kernel answer when
NETNSA_TARGET_NSID is provided, thus the user can easily convert nsids.

Use the new boolopt API to add an option which disables learning from
link-local packets. The default is kept as before and learning is
enabled. This is a simple map from a boolopt bit to a bridge private

We have been adding many new bridge options, a big number of which are
boolean but still take up netlink attribute ids and waste space in the skb.
Recently we discussed learning from link-local packets[1] and decided
yet another new boolean option will be needed, thus introducing this API
to save some bridge nl space.
The API supports changing the value of multiple boolean options at once
via the br_boolopt_multi struct which has an optmask (which options to
set, bit per opt) and optval (options' new values). Future boolean
options will only be added to the br_boolopt_id enum and then will have
to be handled in br_boolopt_toggle/get. The API will automatically
add the ability to change and export them via netlink, sysfs can use the
single boolopt function versions to do the same. The behaviour with
failing/succeeding is the same as with normal netlink option changing.
If an option requires mapping to internal kernel flag or needs special
configuration to be enabled then it should be handled in
br_boolopt_toggle. It should also be able to retrieve an option's current
state via br_boolopt_get.
v2: WARN_ON() on unsupported option as that shouldn't be possible and
also will help catch people who add new options without handling
them for both set and get. Pass down extack so if an option desires
it could set it on error and be more user-friendly.

pull-request: bpf-next 2018-11-26
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Extend BTF to support function call types and improve the BPF
symbol handling with this info for kallsyms and bpftool program
dump to make debugging easier, from Martin and Yonghong.
2) Optimize LPM lookups by making longest_prefix_match() handle
multiple bytes at a time, from Eric.
3) Adds support for loading and attaching flow dissector BPF progs
from bpftool, from Stanislav.
4) Extend the sk_lookup() helper to be supported from XDP, from Nitin.
5) Enable verifier to support narrow context loads with offset > 0
to adapt to LLVM code generation (currently only offset of 0 was
supported). Add test cases as well, from Andrey.
6) Simplify passing device functions for offloaded BPF progs by
adding callbacks to bpf_prog_offload_ops instead of ndo_bpf.
Also convert nfp and netdevsim to make use of them, from Quentin.
7) Add support for sock_ops based BPF programs to send events to
the perf ring-buffer through perf_event_output helper, from
Sowmini and Daniel.
8) Add read / write support for skb->tstamp from tc BPF and cg BPF
programs to allow for supporting rate-limiting in EDT qdiscs
like fq from BPF side, from Vlad.
9) Extend libbpf API to support map in map types and add test cases
for it as well to BPF kselftests, from Nikita.
10) Account the maximum packet offset accessed by a BPF program in
the verifier and use it for optimizing nfp JIT, from Jiong.
11) Fix error handling regarding kprobe_events in BPF sample loader,
from Daniel T.
12) Add support for queue and stack map type in bpftool, from David.

This could be used to rate limit egress traffic in concert with a qdisc
which supports Earliest Departure Time, such as FQ.
Write access from cg skb progs only with CAP_SYS_ADMIN, since the value
will be used by downstream qdiscs. It might make sense to relax this.
Changes v1 -> v2:
- allow access from cg skb, write only with CAP_SYS_ADMIN

This patch added interface to load a program with the following
additional information:
. prog_btf_fd
. func_info, func_info_rec_size and func_info_cnt
where func_info will provide function range and type_id
corresponding to each function.
The func_info_rec_size is introduced in the UAPI to specify
struct bpf_func_info size passed from user space. This
intends to make bpf_func_info structure growable in the future.
If the kernel gets a different bpf_func_info size from userspace,
it will try to handle user request with part of bpf_func_info
it can understand. In this patch, kernel can understand
struct bpf_func_info {
__u32 insn_offset;
__u32 type_id;
};
If user passed a bpf func_info record size of 16 bytes, the
kernel can still handle part of records with the above definition.
If verifier agrees with function range provided by the user,
the bpf_prog ksym for each function will use the func name
provided in the type_id, which is supposed to provide better
encoding as it is not limited by 16 bytes program name
limitation and this is better for bpf program which contains
multiple subprograms.
The bpf_prog_info interface is also extended to
return btf_id, func_info, func_info_rec_size and func_info_cnt
to userspace, so userspace can print out the function prototype
for each xlated function. The insn_offset in the returned
func_info corresponds to the insn offset for xlated functions.
With other jit related fields in bpf_prog_info, userspace can also
print out function prototypes for each jited function.

This patch adds BTF_KIND_FUNC and BTF_KIND_FUNC_PROTO
to support the function debug info.
BTF_KIND_FUNC_PROTO must not have a name (i.e. !t->name_off)
and it is followed by >= 0 'struct bpf_param' objects to
describe the function arguments.
The BTF_KIND_FUNC must have a valid name and it must
refer back to a BTF_KIND_FUNC_PROTO.
The above is the conclusion after the discussion between
Edward Cree, Alexei, Daniel, Yonghong and Martin.
By combining BTF_KIND_FUNC and BTF_LIND_FUNC_PROTO,
a complete function signature can be obtained. It will be
used in the later patches to learn the function signature of

This patch extends the ncsi-netlink interface with two new commands and
three new attributes to configure multiple packages and/or channels at
once, and configure specific failover modes.
NCSI_CMD_SET_PACKAGE mask and NCSI_CMD_SET_CHANNEL_MASK set a whitelist
of packages or channels allowed to be configured with the
NCSI_ATTR_PACKAGE_MASK and NCSI_ATTR_CHANNEL_MASK attributes
respectively. If one of these whitelists is set only packages or
channels matching the whitelist are considered for the channel queue in
ncsi_choose_active_channel().
These commands may also use the NCSI_ATTR_MULTI_FLAG to signal that
multiple packages or channels may be configured simultaneously. NCSI
hardware arbitration (HWA) must be available in order to enable
multi-package mode. Multi-channel mode is always available.
If the NCSI_ATTR_CHANNEL_ID attribute is present in the
NCSI_CMD_SET_CHANNEL_MASK command the it sets the preferred channel as
with the NCSI_CMD_SET_INTERFACE command. The combination of preferred
channel and channel whitelist defines a primary channel and the allowed
failover channels.
If the NCSI_ATTR_MULTI_FLAG attribute is also present then the preferred
channel is configured for Tx/Rx and the other channels are enabled only
for Rx.

Allow users to set and dump RED flags (ECN enabled and harddrop)
on per-virtual queue basis. Validation of attributes is split
from changes to make sure we won't have to undo previous operations
when we find out configuration is invalid.
The objective is to allow changing per-Qdisc parameters without
overwriting the per-vq configured flags.
Old user space will not pass the TCA_GRED_VQ_FLAGS attribute and
per-Qdisc flags will always get propagated to the virtual queues.
New user space which wants to make use of per-vq flags should set
per-Qdisc flags to 0 and then configure per-vq flags as it
sees fit. Once per-vq flags are set per-Qdisc flags can't be
changed to non-zero. Vice versa - if the per-Qdisc flags are
non-zero the TCA_GRED_VQ_FLAGS attribute has to either be omitted
or set to the same value as per-Qdisc flags.
Update per-Qdisc parameters:
per-Qdisc | per-VQ | result
0 | 0 | all vq flags updated
0 | non-0 | error (vq flags in use)
non-0 | 0 | -- impossible --
non-0 | non-0 | all vq flags updated
Update per-VQ state (flags parameter not specified):
no change to flags
Update per-VQ state (flags parameter set):
per-Qdisc | per-VQ | result
0 | any | per-vq flags updated
non-0 | 0 | -- impossible --

Similar to 80ba92fa1a ("codel: add ce_threshold attribute")
After EDT adoption, it became easier to implement DCTCP-like CE marking.
In many cases, queues are not building in the network fabric but on
the hosts themselves.
If packets leaving fq missed their Earliest Departure Time by XXX usec,
we mark them with ECN CE. This gives a feedback (after one RTT) to
the sender to slow down and find better operating mode.

The PTP_SYS_OFFSET ioctl, which can be used to measure the offset
between a PHC and the system clock, includes the total time that the
driver needs to read the PHC timestamp.
This typically involves reading of multiple PCI registers (sometimes in
multiple iterations) and the register that contains the lowest bits of
the timestamp is not read in the middle between the two readings of the
system clock. This asymmetry causes the measured offset to have a
significant error.
Introduce a new ioctl, driver function, and helper functions, which
allow the reading of the lowest register to be isolated from the other
readings in order to reduce the asymmetry. The ioctl returns three
timestamps for each measurement:
- system time right before reading the lowest bits of the PHC timestamp
- PHC time
- system time immediately after reading the lowest bits of the PHC
timestamp

It is strongly RECOMMENDED that Path MTU Discovery ([RFC1191],

packets are transmitted over IPv4 (this is the default with IPv6).
Now that ICMP error handling is working for GENEVE, we can comply with
this recommendation.
Make this configurable, though, to avoid breaking existing setups. By
default, DF won't be set. It can be set or inherited from inner IPv4
packets. If it's configured to be inherited and we are encapsulating IPv6,
it will be set.
This only applies to non-lwt tunnels: if an external control plane is
used, tunnel key will still control the DF flag.

Allow users to set the IPv4 DF bit in outgoing packets, or to inherit its
value from the IPv4 inner header. If the encapsulated protocol is IPv6 and
DF is configured to be inherited, always set it.
For IPv4, inheriting DF from the inner header was probably intended from
the very beginning judging by the comment to vxlan_xmit(), but it wasn't
actually implemented -- also because it would have done more harm than
good, without handling for ICMP Fragmentation Needed messages.
According to RFC 7348, "Path MTU discovery MAY be used". An expired RFC
draft, draft-saum-nvo3-pmtud-over-vxlan-05, whose purpose was to describe
PMTUD implementation, says that "is a MUST that Vxlan gateways [...]
SHOULD set the DF-bit [...]", whatever that means.
Given this background, the only sane option is probably to let the user
decide, and keep the current behaviour as default.
This only applies to non-lwt tunnels: if an external control plane is
used, tunnel key will still control the DF flag.

This change introduces a side effect in respect to UDP tunnels:
after a UDP tunnel creation, now the kernel performs a lookup per ingress
UDP packet, while before such lookup happened only if the ingress packet
carried a valid internal header csum.
rfc v2 -> rfc v3:
- fixed typos in macro name and comments
- really enforce UDP_GRO_CNT_MAX, instead of UDP_GRO_CNT_MAX + 1
- acquire socket lock in UDP_GRO setsockopt
rfc v1 -> rfc v2:
- use a new option to enable UDP GRO
- use static keys to protect the UDP GRO socket lookup

This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

they're rolled together in the asym_eds_op() operation and there's an

a few patches on the mailing list that were posted early in the merge
window I'd like to let those bake for another round -- this was a fairly
big release as far as RISC-V is concerened, and we need to walk before
we can run.
As far as the patches that made it go:
* A patch to ignore offline CPUs when calculating AT_HWCAP. This should
fix GDB on the HiFive unleashed, which has an embedded core for hart
0 which is exposed to Linux as an offline CPU.
* A move of EM_RISCV to elf-em.h, which is where it should have been to
begin with.
* I've also removed the 64-bit divide routines. I know I'm not really
playing by my own rules here because I posted the patches this
morning, but since they shouldn't be in the kernel I think it's better
to err on the side of going too fast here.
I don't anticipate any more patch sets for the merge window.

Pull new experimental media request API from Mauro Carvalho Chehab:
"A new media request API
This API is needed to support device drivers that can dynamically
change their parameters for each new frame. The latest versions of
Google camera and codec HAL depends on such feature.
At this stage, it supports only stateless codecs.
It has been discussed for a long time (at least over the last 3-4
years), and we finally reached to something that seem to work.
This series contain both the API and core changes required to support
it and a new m2m decoder driver (cedrus).
As the current API is still experimental, the only real driver using
it (cedrus) was added at staging[1]. We intend to keep it there for a
while, in order to test the API. Only when we're sure that this API
works for other cases (like encoders), we'll move this driver out of
staging and set the API into a stone.
[1] We added support for the vivid virtual driver (used only for
testing) to it too, as it makes easier to test the API for the ones
that don't have the cedrus hardware"

When synthesizing FORK events, we are trying to create thread objects
for the already running tasks on the machine.
Normally, for a kernel FORK event, we want to clone the parent's maps
because that is what the kernel just did.
But when synthesizing, this should not be done. If we do, we end up
with overlapping maps as we process the sythesized MMAP2 events that
get delivered shortly thereafter.
Use the FORK event misc flags in an internal way to signal this
situation, so we can elide the map clone when appropriate.

Here is the big tty and serial pull request for 4.20-rc1
Lots of little things here, including a merge from the SPI tree in order
to keep things simpler for everyone to sync around for one platform.
Major stuff is:
- tty buffer clearing after use
- atmel_serial fixes and additions
- xilinx uart driver updates
and of course, lots of tiny fixes and additions to individual serial
drivers.
All of these have been in linux-next with no reported issues for a
while.
