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.

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 13b25489b6f8 ("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.

an uninitialized pipe buf.
The underlying cause is that this code assumes sk_msg_memcopy_from_iter()

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.

Pull ring-buffer fixes from Steven Rostedt:
- 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.

For the most part of the C++ history, it couldn't have type
declarations inside anonymous unions for different reasons. At the
same time, __struct_group() relies on the latters, so when the @TAG
argument is not empty, C++ code doesn't want to build (even under
`extern "C"`):
../linux/include/uapi/linux/pkt_cls.h:25:24: error:
'struct tc_u32_sel::<unnamed union>::tc_u32_sel_hdr,' invalid;
an anonymous union may only have public non-static data members
[-fpermissive]
The safest way to fix this without trying to switch standards (which
is impossible in UAPI anyway) etc., is to disable tag declaration
for that language. This won't break anything since for now it's not
buildable at all.
Use a separate definition for __struct_group() when __cplusplus is
defined to mitigate the error, including the version from tools/.

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.

A recent patch inadvertently broke callbacks for NFSv4.0.
In the 4.0 case we do not expect a session to be found but still need to

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().

====================
gve: various XDP fixes
This patch series contains the following XDP fixes:
- clean up XDP tx queue when stopping rings
- use RCU synchronization to guard existence of XDP queues
- perform XSK TX as part of RX NAPI to fix busy polling
- fix XDP allocation issues when non-XDP configurations occur

This patch fixes a number of consistency issues in the queue allocation
path related to XDP.
As it stands, the number of allocated XDP queues changes in three
different scenarios.
1) Adding an XDP program while the interface is up via
gve_add_xdp_queues
2) Removing an XDP program while the interface is up via
gve_remove_xdp_queues
3) After queues have been allocated and the old queue memory has been
removed in gve_queues_start.
However, the requirement for the interface to be up for
gve_(add|remove)_xdp_queues to be called, in conjunction with the fact
that the number of queues stored in priv isn't updated until _after_ XDP
queues have been allocated in the normal queue allocation path means
that if an XDP program is added while the interface is down, XDP queues
won't be added until the _second_ if_up, not the first.
Given the expectation that the number of XDP queues is equal to the
number of RX queues, scenario (3) has another problematic implication.
When changing the number of queues while an XDP program is loaded, the
number of XDP queues must be updated as well, as there is logic in the
driver (gve_xdp_tx_queue_id()) which relies on every RX queue having a
corresponding XDP TX queue. However, the number of XDP queues stored in
priv would not be updated until _after_ a close/open leading to a
mismatch in the number of XDP queues reported vs the number of XDP
queues which actually exist after the queue count update completes.
This patch remedies these issues by doing the following:
1) The allocation config getter function is set up to retrieve the
_expected_ number of XDP queues to allocate instead of relying
on the value stored in `priv` which is only updated once the queues
have been allocated.
2) When adjusting queues, XDP queues are adjusted to match the number of
RX queues when XDP is enabled. This only works in the case when
queues are live, so part (1) of the fix must still be available in
the case that queues are adjusted when there is an XDP program and
the interface is down.

When busy polling is enabled, xsk_sendmsg for AF_XDP zero copy marks
the NAPI ID corresponding to the memory pool allocated for the socket.
In GVE, this NAPI ID will never correspond to a NAPI ID of one of the
dedicated XDP TX queues registered with the umem because XDP TX is not
set up to share a NAPI with a corresponding RX queue.
This patch moves XSK TX descriptor processing from the TX NAPI to the RX
NAPI, and the gve_xsk_wakeup callback is updated to use the RX NAPI
instead of the TX NAPI, accordingly. The branch on if the wakeup is for
TX is removed, as the NAPI poll should be invoked whether the wakeup is
for TX or for RX.
