My tests run an allyesconfig build and it failed with the following errors:
LD [M] samples/kfifo/dma-example.ko
ld.lld: error: undefined symbol: nec7210_board_reset
ld.lld: error: undefined symbol: nec7210_read
ld.lld: error: undefined symbol: nec7210_write
It appears that some modules call the function nec7210_board_reset()
that is defined in nec7210.c. In an allyesconfig build, these other
modules are built in. But the file that holds nec7210_board_reset()
has:
obj-m += nec7210.o
Where that "-m" means it only gets built as a module. With the other
modules built in, they have no access to nec7210_board_reset() and the build
fails.
This isn't the only function. After fixing that one, I hit another:
ld.lld: error: undefined symbol: push_gpib_event
ld.lld: error: undefined symbol: gpib_match_device_path
Where push_gpib_event() was also used outside of the file it was defined
in, and that file too only was built as a module.
Since the directory that nec7210.c is only traversed when
CONFIG_GPIB_NEC7210 is set, and the directory with gpib_common.c is only
traversed when CONFIG_GPIB_COMMON is set, use those configs as the
option to build those modules. When it is an allyesconfig, then they
will both be built in and their functions will be available to the other
modules that are also built in.
Fixes: 3ba84ac69b ("staging: gpib: Add nec7210 GPIB chip driver")
Fixes: 9dde4559e9 ("staging: gpib: Add GPIB common core driver")

Pull PCI fixes from Krzysztof Wilczyński:
"Two small patches that are important for fixing boot time hang on
Intel JHL7540 'Titan Ridge' platforms equipped with a Thunderbolt
controller.
The boot time issue manifests itself when a PCI Express bandwidth
control is unnecessarily enabled on the Thunderbolt controller
downstream ports, which only supports a link speed of 2.5 GT/s in
accordance with USB4 v2 specification (p. 671, sec. 11.2.1, "PCIe
Physical Layer Logical Sub-block").
As such, there is no need to enable bandwidth control on such
downstream port links, which also works around the issue.
Both patches were tested by the original reporter on the hardware on
which the failure origin golly manifested itself. Both fixes were
proven to resolve the reported boot hang issue, and both patches have
been in linux-next this week with no reported problems"

Since commit 13b25489b6 ("kbuild: change working directory to external
module directory with M="), module paths are always relative to the top
of the external module tree.
The module paths recorded in Module.symvers are no longer globally unique
when they are passed via KBUILD_EXTRA_SYMBOLS for building other external
modules, which may result in false-positive "exported twice" errors.
Such errors should not occur because external modules should be able to
override in-tree modules.
To address this, record the dump file path in struct module and check it
when searching for a module.

Stop installing Debian maintainer scripts when building a
user-mode-linux Debian package.
Debian maintainer scripts are used for e.g. requesting rebuilds of
initrd, rebuilding DKMS modules and updating of grub configuration. As
all of this is not relevant for UML but also may lead to failures while
processing the kernel hooks, do no more install maintainer scripts for
the UML package.

skb_network_offset() and skb_transport_offset() can be negative when
they are called after we pull the transport header, for example, when
we use eBPF sockmap at the point of ->sk_data_ready().
__bpf_skb_min_len() uses an unsigned int to get these offsets, this
leads to a very large number which then causes bpf_skb_change_tail()
failed unexpectedly.
Fix this by using a signed int to get these offsets and ensure the
minimum is at least zero.

This is caused by tcp_bpf_sendmsg() returning a larger value(12289) than
size (8192), which causes the while loop in splice_to_socket() to release
an uninitialized pipe buf.
The underlying cause is that this code assumes sk_msg_memcopy_from_iter()
will copy all bytes upon success but it actually might only copy part of
it.
This commit changes it to use the real copied bytes.

These platform won't receive updated bootloader/firmware, so add an
exclusion for platforms with a "coreboot" compatible node. While this is
wider than necessary, that's the easiest fix and it doesn't doesn't
matter if we miss checking other platforms using coreboot.
We may revisit this later and address with a fixup to the DT itself.

- Fix possible overflow of mmapped ring buffer with bad offset
If the mmap() to the ring buffer passes in a start address that
is passed the end of the mmapped file, it is not caught and
a slab-out-of-bounds is triggered.
Add a check to make sure the start address is within the bounds
- Do not use TP_printk() to boot mapped ring buffers
As a boot mapped ring buffer's data may have pointers that map to
the previous boot's memory map, it is unsafe to allow the TP_printk()
to be used to read the boot mapped buffer's events. If a TP_printk()
points to a static string from within the kernel it will not match
the current kernel mapping if KASLR is active, and it can fault.
Have it simply print out the raw fields.

When we do sk_psock_verdict_apply->sk_psock_skb_ingress, an sk_msg will
be created out of the skb, and the rmem accounting of the sk_msg will be
handled by the skb.
For skmsgs in __SK_REDIRECT case of tcp_bpf_send_verdict, when redirecting
to the ingress of a socket, although we sk_rmem_schedule and add sk_msg to
the ingress_msg of sk_redir, we do not update sk_rmem_alloc. As a result,
except for the global memory limit, the rmem of sk_redir is nearly
unlimited. Thus, add sk_rmem_alloc related logic to limit the recv buffer.
Since the function sk_msg_recvmsg and __sk_psock_purge_ingress_msg are
used in these two paths. We use "msg->skb" to test whether the sk_msg is
skb backed up. If it's not, we shall do the memory accounting explicitly.

When bpf_tcp_ingress() is called, the skmsg is being redirected to the
ingress of the destination socket. Therefore, we should charge its
receive socket buffer, instead of sending socket buffer.
Because sk_rmem_schedule() tests pfmemalloc of skb, we need to
introduce a wrapper and call it for skmsg.

We are seeing a sparse warning in gcs_restore_signal():
arch/arm64/kernel/signal.c:1054:9: sparse: sparse: cast removes address space '__user' of expression
when storing the final GCSPR_EL0 value back into the register, caused by
the fact that write_sysreg_s() casts the value it writes to a u64 which
sparse sees as discarding the __userness of the pointer.
Avoid this by treating the address as an integer, casting to a pointer only
when using it to write to userspace.
While we're at it also inline gcs_signal_cap_valid() into it's one user
and make equivalent updates to gcs_signal_entry().

task work can be executed after the task has gone through io_uring
termination, whether it's the final task_work run or the fallback path.
In this case, task work will find ->io_wq being already killed and
null'ed, which is a problem if it then tries to forward the request to
io_queue_iowq(). Make io_queue_iowq() fail requests in this case.
Note that it also checks PF_KTHREAD, because the user can first close
a DEFER_TASKRUN ring and shortly after kill the task, in which case
->iowq check would race.

If a PCIe port only supports a single speed, enabling bandwidth control
is pointless: There's no need to monitor autonomous speed changes, nor
can the speed be changed.
Not enabling it saves a small amount of memory and compute resources,
but also fixes a boot hang reported by Niklas: It occurs when enabling
bandwidth control on Downstream Ports of Intel JHL7540 "Titan Ridge 2018"
Thunderbolt controllers. The ports only support 2.5 GT/s in accordance
with USB4 v2 sec 11.2.1, so the present commit works around the issue.
PCIe r6.2 sec 8.2.1 prescribes that:
"A device must support 2.5 GT/s and is not permitted to skip support
for any data rates between 2.5 GT/s and the highest supported rate."
Consequently, bandwidth control is currently only disabled if a port
doesn't support higher speeds than 2.5 GT/s. However the Implementation
Note in PCIe r6.2 sec 7.5.3.18 cautions:
"It is strongly encouraged that software primarily utilize the
Supported Link Speeds Vector instead of the Max Link Speed field,
so that software can determine the exact set of supported speeds on
current and future hardware. This can avoid software being confused
if a future specification defines Links that do not require support
for all slower speeds."
In other words, future revisions of the PCIe Base Spec may allow gaps
in the Supported Link Speeds Vector. To be future-proof, don't just
check whether speeds above 2.5 GT/s are supported, but rather check
whether *more than one* speed is supported.

The Supported Link Speeds Vector in the Link Capabilities 2 Register
indicates the *supported* link speeds. The Max Link Speed field in the
Link Capabilities Register indicates the *maximum* of those speeds.
pcie_get_supported_speeds() neglects to honor the Max Link Speed field and
will thus incorrectly deem higher speeds as supported. Fix it.
One user-visible issue addressed here is an incorrect value in the sysfs
attribute "max_link_speed".
But the main motivation is a boot hang reported by Niklas: Intel JHL7540
"Titan Ridge 2018" Thunderbolt controllers supports 2.5-8 GT/s speeds,
but indicate 2.5 GT/s as maximum. Ilpo recalls seeing this on more
devices. It can be explained by the controller's Downstream Ports
supporting 8 GT/s if an Endpoint is attached, but limiting to 2.5 GT/s
if the port interfaces to a PCIe Adapter, in accordance with USB4 v2
sec 11.2.1:
"This section defines the functionality of an Internal PCIe Port that
interfaces to a PCIe Adapter. [...]
The Logical sub-block shall update the PCIe configuration registers
with the following characteristics: [...]
Max Link Speed field in the Link Capabilities Register set to 0001b
(data rate of 2.5 GT/s only).
Note: These settings do not represent actual throughput. Throughput
is implementation specific and based on the USB4 Fabric performance."
The present commit is not sufficient on its own to fix Niklas' boot hang,
but it is a prerequisite: A subsequent commit will fix the boot hang by
enabling bandwidth control only if more than one speed is supported.
The GENMASK() macro used herein specifies 0 as lowest bit, even though
the Supported Link Speeds Vector ends at bit 1. This is done on purpose
to avoid a GENMASK(0, 1) macro if Max Link Speed is zero. That macro
would be invalid as the lowest bit is greater than the highest bit.
Ilpo has witnessed a zero Max Link Speed on Root Complex Integrated
Endpoints in particular, so it does occur in practice. (The Link
Capabilities Register is optional on RCiEPs per PCIe r6.2 sec 7.5.3.)

With DEFER_TASKRUN, we know the ring can't be both waited upon and
resized at the same time. This is important for CQ resizing. Allowing SQ
ring resizing is more trivial, but isn't the interesting use case. Hence
limit ring resizing in general to DEFER_TASKRUN only for now. This isn't
a huge problem as CQ ring resizing is generally the most useful on
networking type of workloads where it can be hard to size the ring
appropriately upfront, and those should be using DEFER_TASKRUN for
better performance.
