RDMA/mlx5: Follow rb_key.ats when creating new mkeys
When a cache ent already exists but doesn't have any mkeys in it the cache
will automatically create a new one based on the specification in the
ent->rb_key.
ent->ats was missed when creating the new key and so ma_translation_mode
was not being set even though the ent requires it.

RDMA/mlx5: Remove extra unlock on error path
The below commit lifted the locking out of this function but left this
error path unlock behind resulting in unbalanced locking. Remove the
missed unlock too.

KVM fixes for 6.10
- Fix a "shift too big" goof in the KVM_SEV_INIT2 selftest.
- Compute the max mappable gfn for KVM selftests on x86 using GuestMaxPhyAddr
from KVM's supported CPUID (if it's available).
- Fix a race in kvm_vcpu_on_spin() by ensuring loads and stores are atomic.
- Fix technically benign bug in __kvm_handle_hva_range() where KVM consumes
the return from a void-returning function as if it were a boolean.

crypto: qat - fix linking errors when PCI_IOV is disabled
When CONFIG_PCI_IOV=n, the build of the QAT vfio pci variant driver
fails reporting the following linking errors:

WARNING: modpost: suppressed 1 unresolved symbol warnings because there were too many)
Make live migration helpers provided by QAT PF driver always available
even if CONFIG_PCI_IOV is not selected. This does not cause any side
effect.

ionic: fix kernel panic due to multi-buffer handling
Currently, the ionic_run_xdp() doesn't handle multi-buffer packets
properly for XDP_TX and XDP_REDIRECT.
When a jumbo frame is received, the ionic_run_xdp() first makes xdp
frame with all necessary pages in the rx descriptor.
And if the action is either XDP_TX or XDP_REDIRECT, it should unmap
dma-mapping and reset page pointer to NULL for all pages, not only the
first page.
But it doesn't for SG pages. So, SG pages unexpectedly will be reused.
It eventually causes kernel panic.

net: pse-pd: Kconfig: Fix missing firmware loader config select
Selecting FW_UPLOAD is not sufficient as it allows the firmware loader

Add select FW_LOADER to fix this issue.

bonding: fix incorrect software timestamping report
The __ethtool_get_ts_info function returns directly if the device has a
get_ts_info() method. For bonding with an active slave, this works correctly
as we simply return the real device's timestamping information. However,
when there is no active slave, we only check the slave's TX software
timestamp information. We still need to set the phc index and RX timestamp
information manually. Otherwise, the result will be look like:
Time stamping parameters for bond0:
Capabilities:
software-transmit
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none
This issue does not affect VLAN or MACVLAN devices, as they only have one
downlink and can directly use the downlink's timestamping information.

can: mcp251xfd: fix infinite loop when xmit fails
When the mcp251xfd_start_xmit() function fails, the driver stops
processing messages, and the interrupt routine does not return,
running indefinitely even after killing the running application.
Error messages:
[ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16
[ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3).
... and repeat forever.
The issue can be triggered when multiple devices share the same SPI
interface. And there is concurrent access to the bus.
The problem occurs because tx_ring->head increments even if
mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX
package while still expecting a response in
mcp251xfd_handle_tefif_one().
Resolve the issue by starting a workqueue to write the tx obj
synchronously if err = -EBUSY. In case of another error, decrement
tx_ring->head, remove skb from the echo stack, and drop the message.

net: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new
This patch enhances error handling in scenarios with RTS (Request to
Send) messages arriving closely. It replaces the less informative WARN_ON_ONCE
backtraces with a new error handling method. This provides clearer error
messages and allows for the early termination of problematic sessions.
Previously, sessions were only released at the end of j1939_xtp_rx_rts().
Potentially this could be reproduced with something like:
testj1939 -r vcan0:0x80 &
while true; do
# send first RTS
cansend vcan0 18EC8090#1014000303002301;
# send second RTS
cansend vcan0 18EC8090#1014000303002301;
# send abort
cansend vcan0 18EC8090#ff00000000002301;

net: dsa: microchip: fix initial port flush problem
The very first flush in any port will flush all learned addresses in all
ports. This can be observed by unplugging the cable from one port while
additional ports are connected and dumping the fdb entries.
This problem is caused by the initially wrong value programmed to the
REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
takes effect and flushes all learned entries. After that call both bits
are reset and so the next port flush will not cause such problem again.

LoongArch: Fix multiple hardware watchpoint issues
In the current code, if multiple hardware breakpoints/watchpoints in
a user-space thread, some of them will not be triggered.
When debugging the following code using gdb.
lihui@bogon:~$ cat test.c
#include <stdio.h>
int a = 0;
int main()
{
printf("start test\n");
a = 1;
printf("a = %d\n", a);
printf("end test\n");
return 0;
}
lihui@bogon:~$ gcc -g test.c -o test
lihui@bogon:~$ gdb test
...
(gdb) start
...
Temporary breakpoint 1, main () at test.c:5
5 printf("start test\n");
(gdb) watch a
Hardware watchpoint 2: a
(gdb) hbreak 8
Hardware assisted breakpoint 3 at 0x1200006ec: file test.c, line 8.
(gdb) c
Continuing.
start test
a = 1
Breakpoint 3, main () at test.c:8
8 printf("end test\n");
...
The first hardware watchpoint is not triggered, the root causes are:
1. In hw_breakpoint_control(), The FWPnCFG1.2.4/MWPnCFG1.2.4 register
settings are not distinguished. They should be set based on hardware
watchpoint functions (fetch or load/store operations).
2. In breakpoint_handler() and watchpoint_handler(), it doesn't identify
which watchpoint is triggered. So, all watchpoint-related perf_event
callbacks are called and siginfo is sent to the user space. This will
cause user-space unable to determine which watchpoint is triggered.
The kernel need to identity which watchpoint is triggered via MWPS/
FWPS registers, and then call the corresponding perf event callbacks
to report siginfo to the user-space.
Modify the relevant code to solve above issues.

LoongArch: Trigger user-space watchpoints correctly
In the current code, gdb can set the watchpoint successfully through
ptrace interface, but watchpoint will not be triggered.
When debugging the following code using gdb.
lihui@bogon:~$ cat test.c
#include <stdio.h>
int a = 0;
int main()
{
a = 1;
printf("a = %d\n", a);
return 0;
}
lihui@bogon:~$ gcc -g test.c -o test
lihui@bogon:~$ gdb test
...
(gdb) watch a
...
(gdb) r
...
a = 1
[Inferior 1 (process 4650) exited normally]
No watchpoints were triggered, the root causes are:
1. Kernel uses perf_event and hw_breakpoint framework to control
watchpoint, but the perf_event corresponding to watchpoint is
not enabled. So it needs to be enabled according to MWPnCFG3
or FWPnCFG3 PLV bit field in ptrace_hbp_set_ctrl(), and privilege
is set according to the monitored addr in hw_breakpoint_control().
Furthermore, add a judgment in ptrace_hbp_set_addr() to ensure
kernel-space addr cannot be monitored in user mode.
2. The global enable control for all watchpoints is the WE bit of
CSR.CRMD, and hardware sets the value to 0 when an exception is
triggered. When the ERTN instruction is executed to return, the
hardware restores the value of the PWE field of CSR.PRMD here.
So, before a thread containing watchpoints be scheduled, the PWE
field of CSR.PRMD needs to be set to 1. Add this modification in
hw_breakpoint_control().

Invalid argument setting hardware debug registers
There are mainly two types of issues.
1. Some incorrect judgment condition existed in user_watch_state
argument parsing, causing -EINVAL to be returned.
When setting up a watchpoint, gdb uses the ptrace interface,
ptrace(PTRACE_SETREGSET, tid, NT_LOONGARCH_HW_WATCH, (void *) &iov)).
Register values in user_watch_state as follows:
addr[0] = 0x0, mask[0] = 0x0, ctrl[0] = 0x0
addr[1] = 0x0, mask[1] = 0x0, ctrl[1] = 0x0
addr[2] = 0x0, mask[2] = 0x0, ctrl[2] = 0x0
addr[3] = 0x0, mask[3] = 0x0, ctrl[3] = 0x0
addr[4] = 0x0, mask[4] = 0x0, ctrl[4] = 0x0
addr[5] = 0x0, mask[5] = 0x0, ctrl[5] = 0x0
addr[6] = 0x0, mask[6] = 0x0, ctrl[6] = 0x0
addr[7] = 0x12000803c, mask[7] = 0x0, ctrl[7] = 0x610
In arch_bp_generic_fields(), return -EINVAL when ctrl.len is
LOONGARCH_BREAKPOINT_LEN_8(0b00). So delete the incorrect judgment here.
In ptrace_hbp_fill_attr_ctrl(), when note_type is NT_LOONGARCH_HW_WATCH
and ctrl[0] == 0x0, if ((type & HW_BREAKPOINT_RW) != type) will return
-EINVAL. Here ctrl.type should be set based on note_type, and unnecessary
judgments can be removed.
2. The watchpoint argument was not set correctly due to unnecessary
offset and alignment_mask.
Modify ptrace_hbp_fill_attr_ctrl() and hw_breakpoint_arch_parse(), which
ensure the watchpont argument is set correctly.

LoongArch: Only allow OBJTOOL & ORC unwinder if toolchain supports -mthin-add-sub
GAS <= 2.41 does not support generating R_LARCH_{32,64}_PCREL for
"label - ." and it generates R_LARCH_{ADD,SUB}{32,64} pairs instead.
Objtool cannot handle R_LARCH_{ADD,SUB}{32,64} pair in __jump_table
(static key implementation) and etc. so it will produce some warnings.
This is causing the kernel CI systems to complain everywhere.
For GAS we can check if -mthin-add-sub option is available to know if
R_LARCH_{32,64}_PCREL are supported.
For Clang, we require Clang >= 18 and Clang >= 17 already supports
R_LARCH_{32,64}_PCREL. But unfortunately Clang has some other issues,
so we disable objtool for Clang at present.
Note that __jump_table here is not generated by the compiler, so
-fno-jump-table is completely irrelevant for this issue.

i2c: ocores: set IACK bit after core is enabled
Setting IACK bit when core is disabled does not clear the "Interrupt Flag"
bit in the status register, and the interrupt remains pending.
Sometimes it causes failure for the very first message transfer, that is
usually a device probe.
Hence, set IACK bit after core is enabled to clear pending interrupt.

KVM: Discard zero mask with function kvm_dirty_ring_reset
Function kvm_reset_dirty_gfn may be called with parameters cur_slot / cur_offset / mask are all zero, it does not represent real dirty page. It is not necessary to clear dirty page in this condition. Also return value of macro __fls() is undefined if mask is zero which is called in funciton kvm_reset_dirty_gfn(). Here just return.

virt: guest_memfd: fix reference leak on hwpoisoned page
If kvm_gmem_get_pfn() detects an hwpoisoned page, it returns -EHWPOISON
but it does not put back the reference that kvm_gmem_get_folio() had
grabbed. Add the forgotten folio_put().

firmware: psci: Fix return value from psci_system_suspend()
Currently we return the value from invoke_psci_fn() directly as return
value from psci_system_suspend(). It is wrong to send the PSCI interface
return value directly. psci_to_linux_errno() provide the mapping from
PSCI return value to the one that can be returned to the callers within
the kernel.
Use psci_to_linux_errno() to convert and return the correct value from
psci_system_suspend().

KVM: x86: Always sync PIR to IRR prior to scanning I/O APIC routes
Sync pending posted interrupts to the IRR prior to re-scanning I/O APIC
routes, irrespective of whether the I/O APIC is emulated by userspace or
by KVM. If a level-triggered interrupt routed through the I/O APIC is
pending or in-service for a vCPU, KVM needs to intercept EOIs on said
vCPU even if the vCPU isn't the destination for the new routing, e.g. if
servicing an interrupt using the old routing races with I/O APIC
reconfiguration.

Happy summer solstice! The line count is a bit inflated by a selftest

usb: gadget: aspeed_udc: fix device address configuration
In the aspeed UDC setup, we configure the UDC hardware with the assigned
USB device address.
However, we have an off-by-one in the bitmask, so we're only setting the
lower 6 bits of the address (USB addresses being 7 bits, and the
hardware bitmask being bits 0:6).
This means that device enumeration fails if the assigned address is
greater than 64:
[ 344.607255] usb 1-1: new high-speed USB device number 63 using ehci-platform
[ 344.808459] usb 1-1: New USB device found, idVendor=cc00, idProduct=cc00, bcdDevice= 6.10
[ 344.817684] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 344.825671] usb 1-1: Product: Test device
[ 344.831075] usb 1-1: Manufacturer: Test vendor
[ 344.836335] usb 1-1: SerialNumber: 00
[ 349.917181] usb 1-1: USB disconnect, device number 63

[ 352.909431] usb 1-1: device descriptor read/all, error -71
Use the correct mask of 0x7f (rather than 0x3f), and generate this
through the GENMASK macro, so we have numbers that correspond exactly
