With hns_dsaf_roce_reset() removed in a previous patch, the two
helper member pointers, 'hns_dsaf_roce_srst', and 'hns_dsaf_srst_chns'
are now unread.
Remove them, and the helper functions that they were initialised
to, that is hns_dsaf_srst_chns(), hns_dsaf_srst_chns_acpi(),
hns_dsaf_roce_srst() and hns_dsaf_roce_srst_acpi().

Empty netlink responses from do() are not correct (as opposed to
dump() where not dumping anything is perfectly fine).
We should return an error if the target object does not exist,
in this case if the netdev is down we "hide" the NAPI instances.

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.

Commit 9dde4559e939 ("staging: gpib: Add GPIB common core driver")
from Sep 18, 2024 (linux-next), leads to the following Smatch static
checker warning:
drivers/staging/gpib/common/gpib_os.c:541 dvrsp()
warn: no lower bound on 'sad' rl='s32min-30'
The value -1 was introduced in user land to signify No secondary address
to the driver so that a lower bound check could be added.
This patch adds that check.

The USB_GPIB_SET_LINES command string used to be: "\nIBDC \n" but when
we were merging this code into the upstream kernel we deleted the space
character before the newline to make checkpatch happy. That turned
out to be a mistake.
The "\nIBDC" part of the string is a command that we pass to the
firmware and the next character is a variable u8 value.
It gets set in set_control_line().
msg[leng - 2] = value ? (retval & ~line) : retval | line;
where leng is the length of the command string.
Imagine the parameter was supposed to be "8".
With the pre-merge code the command string would be "\nIBDC8\n"
With the post-merge code the command string became "\nIBD8\n"
The firmware doesn't recognize "IBD8" as a valid command and rejects it.
Putting a "." where the parameter is supposed to go fixes the driver
and makes checkpatch happy. Same thing with the other define and
the in-line assignment.

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
call setup_callback_client() which will not try to dereference it.
This patch moves the check for failure to find a session into the 4.1+
branch of setup_callback_client()

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.

This patch predicates the enabling and disabling of XSK pools on the
existence of queues. As it stands, if the interface is down, disabling
or enabling XSK pools would result in a crash, as the RX queue pointer
would be NULL. XSK pool registration will occur as part of the next
interface up.
Similarly, xsk_wakeup needs be guarded against queues disappearing
while the function is executing, so a check against the
GVE_PRIV_FLAGS_NAPI_ENABLED flag is added to synchronize with the
disabling of the bit and the synchronize_net() in gve_turndown.

In GVE, dedicated XDP queues only exist when an XDP program is installed
and the interface is up. As such, the NDO XDP XMIT callback should
return early if either of these conditions are false.
In the case of no loaded XDP program, priv->num_xdp_queues=0 which can
cause a divide-by-zero error, and in the case of interface down,
num_xdp_queues remains untouched to persist XDP queue count for the next
interface up, but the TX pointer itself would be NULL.
The XDP xmit callback also needs to synchronize with a device
transitioning from open to close. This synchronization will happen via
the GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call,
which waits for any RCU critical sections at call-time to complete.

When stopping XDP TX rings, the XDP clean function needs to be called to
clean out the entire queue, similar to what happens in the normal TX
queue case. Otherwise, the FIFO won't be cleared correctly, and
xsk_tx_completed won't be reported.

The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular
dependency on the global-timer target due to its inclusion in
$(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency
warning during the build process.
To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been
replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change
ensures that libatest.so is built before any other targets that require it,
without creating a circular dependency.
This fix addresses the following warning:
make[4]: Entering directory 'tools/testing/selftests/alsa'
