Yonghong Song says:
====================
Andrii raised a concern that current uapi for bpf iterator map
element is a little restrictive and not suitable for future potential
complex customization. This is a valid suggestion, considering people
may indeed add more complex custimization to the iterator, e.g.,
cgroup_id + user_id, etc. for task or task_file. Another example might
be map_id plus additional control so that the bpf iterator may bail
out a bucket earlier if a bucket has too many elements which may hold
lock too long and impact other parts of systems.
Patch #1 modified uapi with kernel changes. Patch #2
adjusted libbpf api accordingly.
Changelogs:
v3 -> v4:
. add a forward declaration of bpf_iter_link_info in
tools/lib/bpf/bpf.h in case that libbpf is built against
not-latest uapi bpf.h.
. target the patch set to "bpf" instead of "bpf-next"
v2 -> v3:
. undo "not reject iter_info.map.map_fd == 0" from v1.
In the future map_fd may become optional, so let us use map_fd == 0
indicating the map_fd is not set by user space.
. add link_info_len to bpf_iter_attach_opts to ensure always correct
link_info_len from user. Otherwise, libbpf may deduce incorrect
link_info_len if it uses different uapi header than the user app.
v1 -> v2:
. ensure link_create target_fd/flags == 0 since they are not used. (Andrii)
. if either of iter_info ptr == 0 or iter_info_len == 0, but not both,
return error to user space. (Andrii)
. do not reject iter_info.map.map_fd == 0, go ahead to use it trying to
get a map reference since the map_fd is required for map_elem iterator.
. use bpf_iter_link_info in bpf_iter_attach_opts instead of map_fd.
this way, user space is responsible to set up bpf_iter_link_info and
libbpf just passes the data to the kernel, simplifying libbpf design.
(Andrii)

Previous commit adjusted kernel uapi for map
element bpf iterator. This patch adjusted libbpf API
due to uapi change. bpftool and bpf_iter selftests
are also changed accordingly.

Commit a5cbe05a66 ("bpf: Implement bpf iterator for
map elements") added bpf iterator support for
map elements. The map element bpf iterator requires
info to identify a particular map. In the above
commit, the attr->link_create.target_fd is used
to carry map_fd and an enum bpf_iter_link_info
is added to uapi to specify the target_fd actually
representing a map_fd:
enum bpf_iter_link_info {
BPF_ITER_LINK_UNSPEC = 0,
BPF_ITER_LINK_MAP_FD = 1,
MAX_BPF_ITER_LINK_INFO,
};
This is an extensible approach as we can grow
enumerator for pid, cgroup_id, etc. and we can
unionize target_fd for pid, cgroup_id, etc.
But in the future, there are chances that
more complex customization may happen, e.g.,
for tasks, it could be filtered based on
both cgroup_id and user_id.
This patch changed the uapi to have fields
__aligned_u64 iter_info;
__u32 iter_info_len;
for additional iter_info for link_create.
The iter_info is defined as
union bpf_iter_link_info {
struct {
__u32 map_fd;
} map;
};
So future extension for additional customization
will be easier. The bpf_iter_link_info will be
passed to target callback to validate and generic
bpf_iter framework does not need to deal it any
more.
Note that map_fd = 0 will be considered invalid
and -EBADF will be returned to user space.

runqslower's Makefile is building/installing bpftool into
$(OUTPUT)/sbin/bpftool, which coincides with $(DEFAULT_BPFTOOL). In practice
this means that often when building selftests from scratch (after `make
clean`), selftests are racing with runqslower to simultaneously build bpftool
and one of the two processes fail due to file being busy. Prevent this race by
explicitly order-depending on $(BPFTOOL_DEFAULT).

"New xilinx displayport driver, AMD support for two new GPUs (more
header files), i915 initial support for RocketLake and some work on

Okay, so... this one is interesting. RGB LEDs are very common, and we
need to have some kind of support for them. Multicolor is for
arbitrary set of LEDs in one package, RGB is for LEDs that can produce
full range of colors. We do not have real multicolor LED that is not
RGB in the pipeline, so that one is disabled for now.
You can expect this saga to continue with next pull requests.

====================
misc bug fixes for the hso driver
1. Code reuse led to an unregistration of a net driver that has not been
registered
2. The kernel complains generically if kmalloc with GFP_KERNEL fails
3. A race that can lead to an URB that is in use being reused or
a use after free
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This check an inherent race. It opens a race where
an error code has already been set or cleared yet
the URB has not been given back. We cannot do
such an optimization and must unlink unconditionally.

If this fails, kmalloc() will print a report including
a stack trace. There is no need for a separate complaint.

The driver tries to reuse code for disconnect in case
of a failed probe.
If resources need to be freed after an error in probe, the
netdev must not be freed because it has never been registered.
Fix it by telling the helper which path we are in.

Before switch from discontigmem to sparsemem, there always was
CONFIG_NEED_MULTIPLE_NODES=y because it was selected by DISCONTIGMEM.
Without DISCONTIGMEM it is possible to have SPARSEMEM without NUMA for
SGI_IP27 and as many things there rely on custom node definition, the
build breaks.
As Thomas noted "... there are right now too many places in IP27 code,
which assumes NUMA enabled", the simplest solution would be to always
enable NUMA for SGI-IP27 builds.

This series adds reporting of the page table order from hmm_range_fault()
and some optimization of migrate_vma():
- Report the size of the page table mapping out of hmm_range_fault(). This
makes it easier to establish a large/huge/etc mapping in the device's
page table.
- Allow devices to ignore the invalidations during migration in cases
where the migration is not going to change pages. For instance migrating
pages to a device does not require the device to invalidate pages
already in the device.
- Update nouveau and hmm_tests to use the above

The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.
But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.
The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.
Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

selftests: rtnetlink: Fix for false-negative return values
This patchset will address the false-negative return value issue
caused by the following:
1. The return value "ret" in this script will be reset to 0 from
the beginning of each sub-test in rtnetlink.sh, therefore this
rtnetlink test will always pass if the last sub-test has passed.
2. The test result from two sub-tests in kci_test_encap() were not
being processed, thus they will not affect the final test result
of this test.

kci_test_encap() is actually composed by two different sub-tests,
kci_test_encap_vxlan() and kci_test_encap_fou()
Therefore we should check the test result of these two in
kci_test_encap() to let the script be aware of the pass / fail status.
Otherwise it will generate false-negative result like below:

Although we can detect the chip revision 100% at runtime, it is useful
to specify it in the device tree compatible string too, because
otherwise there would be no way to assess the correctness of device tree
bindings statically, without booting a board (only some switch versions
have internal RGMII delays and/or an SGMII port).
But for testing the P/Q/R/S support, what I have is a reworked board
with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
want to keep a separate device tree blob just for this one-off board.
Since just the chip has been replaced, its RGMII delay setup is
inherently the same (meaning: delays added by the PHY on the slave
ports, and by PCB traces on the fixed-link CPU port).
For this board, I'd rather have the driver shout at me, but go ahead and
use what it found even if it doesn't match what it's been told is there.
[ 2.970826] sja1105 spi0.1: Device tree specifies chip SJA1105T but found SJA1105Q, please fix it!

Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
ipv6_sock_mc_join() may make the wrong dev join the multicast

never be created.
So fix it by getting the right netdev and setting ub->ifindex,

This reverts commit 71130f2997.
In commit 71130f2997 ("vxlan: fix tos value before xmit") we want to
make sure the tos value are filtered by RT_TOS() based on RFC1349.
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| PRECEDENCE | TOS | MBZ |
+-----+-----+-----+-----+-----+-----+-----+-----+
But RFC1349 has been obsoleted by RFC2474. The new DSCP field defined like
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| DS FIELD, DSCP | ECN FIELD |
+-----+-----+-----+-----+-----+-----+-----+-----+
So with
IPTOS_TOS_MASK 0x1E
RT_TOS(tos) ((tos)&IPTOS_TOS_MASK)
the first 3 bits DSCP info will get lost.
To take all the DSCP info in xmit, we should revert the patch and just push
all tos bits to ip_tunnel_ecn_encap(), which will handling ECN field later.

Here is the "big" set of changes to the driver core, and some drivers
using the changes, for 5.9-rc1.
"Biggest" thing in here is the device link exposure in sysfs, to help
to tame the madness that is SoC device tree representations and driver
interactions with it.
Other stuff in here that is interesting is:
- device probe log helper so that drivers can report problems in
a unified way easier.
- devres functions added
- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
incorrect sysfs file permissions
- documentation cleanups
- ability for debugfs to be present in the kernel, yet not
exposed to userspace. Needed for systems that want it
enabled, but do not trust users, so they can still use some
kernel functions that were otherwise disabled.
- other minor fixes and cleanups
The patches outside of drivers/base/ all have acks from the respective
subsystem maintainers to go through this tree instead of theirs.
All of these have been in linux-next with no reported issues.

userspace. Needed for systems that want it enabled, but do not
trust users, so they can still use some kernel functions that were
otherwise disabled.
- other minor fixes and cleanups
The patches outside of drivers/base/ all have acks from the respective
subsystem maintainers to go through this tree instead of theirs.

syzbot has revealed that the "phylink" keyword exists in non-phylink
related contexts in the bluetooth stack. To avoid receiving
inappropriate notifications, change the keyword matching regexp to
something which avoids this, while still allowing changes to networking
drivers that make use of phylink to be detected.

This Kunit update for Linux 5.9-rc1 consists of:
- Adds a generic kunit_resource API extending it to support
resources that are passed in to kunit in addition kunit
allocated resources. In addition, KUnit resources are now
refcounted to avoid passed in resources being released while
in use by kunit.
- Add support for named resources.
- Important bug fixes from Brendan Higgins and Will Chen
