eeprom: at25: fram: Detect and support inside-out chip variants
Infineon seems to be confused with the order ID bytes should be presented
by the FRAM chips and to be on the safe side they offer chips which are
either JEDEC conform or the full opposite of the latter.
Examples of the chips which present ID bytes in the reversed order are:
CY15B102QN
CY15B204QSN
Let's support them nevertheless. Except reversing the ID bytes, they also
have quite different density encoding even across EXCELON(tm) family.
The patch has been tested with the above two chips.
misc: fastrpc: Use of_reserved_mem_region_to_resource() for "memory-region"
Use the newly added of_reserved_mem_region_to_resource() function to
handle "memory-region" properties.
The error handling is a bit different. "memory-region" is optional, so
failed lookup is not an error. But then an error in
of_reserved_mem_lookup() is treated as an error. However, that
distinction is not really important. Either the region is available
and usable or it is not. So now, it is just
of_reserved_mem_region_to_resource() which is checked for an error.
mcb: use sysfs_emit_at() instead of scnprintf() in show functions
This change improves clarity and ensures proper bounds checking in
line with the preferred sysfs_emit() API usage for sysfs 'show'
functions. The PAGE_SIZE check is now handled internally by the helper.
No functional change intended.

binder: encapsulate individual alloc test cases
Each case tested by the binder allocator test is defined by 3 parameters:
the end alignment type of each requested buffer allocation, whether those
buffers share the front or back pages of the allotted address space, and
the order in which those buffers should be released. The alignment type
represents how a binder buffer may be laid out within or across page
boundaries and relative to other buffers, and it's used along with
whether the buffers cover part (sharing the front pages) of or all
(sharing the back pages) of the vma to calculate the sizes passed into
each test.
binder_alloc_test_alloc recursively generates each possible arrangement
of alignment types and then tests that the binder_alloc code tracks pages
correctly when those buffers are allocated and then freed in every
possible order at both ends of the address space. While they provide
comprehensive coverage, they are poor candidates to be represented as
KUnit test cases, which must be statically enumerated. For 5 buffers and
5 end alignment types, the test case array would have 750,000 entries.
This change structures the recursive calls into meaningful test cases so
that failures are easier to interpret.

A binder process's binder_alloc->freelist should not be changed after
it is initialized. A sole exception is the process that runs the
existing binder_alloc selftest. Its freelist can be temporarily replaced
for the duration of the test because it runs as a single thread before
any pages can be added to the global binder freelist, and the test frees

doing "fun" pointer math like this really isn't a write off the end of

greybus: gb-beagleplay: remove unneeded calls to devm_gpiod_put()
gb_fw_init() is only called in this driver's probe() and we abort the
probing if it fails. This means that calling devm_gpiod_put() in error
path is not required as devres will already manage the releasing of the
resources when the device is detached.
Because pps_cdev_poll() returns unconditionally EPOLLIN,
a user space program that calls select/poll get always an immediate data
ready-to-read response. As a result the intended use to wait until next
data becomes ready does not work.
User space snippet:
struct pollfd pollfd = {
.fd = open("/dev/pps0", O_RDONLY),
.events = POLLIN|POLLERR,
.revents = 0 };
while(1) {
poll(&pollfd, 1, 2000/*ms*/); // returns immediate, but should wait
if(revents & EPOLLIN) { // always true
struct pps_fdata fdata;
memset(&fdata, 0, sizeof(memdata));
ioctl(PPS_FETCH, &fdata); // currently fetches data at max speed
}
}
Lets remember the last fetch event counter and compare this value
in pps_cdev_poll() with most recent event counter
and return 0 if they are equal.

pps: clients: gpio: fix interrupt handling order in remove path
The interrupt handler in pps_gpio_probe() is registered after calling
pps_register_source() using devm_request_irq(). However, in the
corresponding remove function, pps_unregister_source() is called before
the IRQ is freed, since devm-managed resources are released after the
remove function completes.
This creates a potential race condition where an interrupt may occur
after the PPS source is unregistered but before the handler is removed,
possibly leading to a kernel panic.
To prevent this, switch from devm-managed IRQ registration to manual
management by using request_irq() and calling free_irq() explicitly in
the remove path before unregistering the PPS source. This ensures the
interrupt handler is safely removed before deactivating the PPS source.

vmci: Prevent the dispatching of uninitialized payloads
The reproducer executes the host's unlocked_ioctl call in two different
tasks. When init_context fails, the struct vmci_event_ctx is not fully
initialized when executing vmci_datagram_dispatch() to send events to all
vm contexts. This affects the datagram taken from the datagram queue of
its context by another task, because the datagram payload is not initialized
according to the size payload_size, which causes the kernel data to leak
to the user space.
Before dispatching the datagram, and before setting the payload content,
explicitly set the payload content to 0 to avoid data leakage caused by
incomplete payload initialization.

Drivers should be silent on probe success, unless they print some useful

- that registering duplicate minors or duplicate names will fail.
- that failing to create a sysfs file (due to duplicate names) will

- that dynamic allocation does not allocate a minor number in the static

- that there are no collisions when mixing dynamic and static allocations.

to use raw-spinlocks only since normal spinlocks can sleep in PREEMPT-RT
kernels and with IRQF_NO_THREAD the interrupt handlers will always run in
an atomic context [1].
vsc_tp_isr() calls wake_up(&tp->xfer_wait), which uses a regular spinlock,
breaking the raw-spinlocks only rule for Intel GPIO ISRs.

tp->assert_cnt and waits for it through the tp->xfer_wait wait-queue.
And tp->assert_cnt is increased and the tp->xfer_wait queue is woken o
from the interrupt handler.
So the interrupt handler which is running the event callback is waiting for
itself to signal that it can continue.
This happens to work because the event callback runs from the threaded
ISR handler and while that is running the hard ISR handler will still
get called a second / third time for further interrupts and it is the hard
ISR handler which does the atomic_inc() and wake_up() calls.
But having the threaded ISR handler wait for its own interrupt to trigger
again is not how a threaded ISR handler is supposed to be used.
Move the running of the event callback from a threaded interrupt handler
to a workqueue since a threaded ISR should not wait for events from its
own interrupt.
This is a preparation patch for moving the atomic_inc() and wake_up() calls

If spacemit_i2c_xfer_msg() times out waiting for a message transfer to
complete, or if the hardware reports an error, it returns a negative
error code (-ETIMEDOUT, -EAGAIN, -ENXIO. or -EIO).
The sole caller of spacemit_i2c_xfer_msg() is spacemit_i2c_xfer(),

has no indication anything is wrong.
When this code was out for review, the return value *was* checked
in early versions. But for some reason, that assignment got dropped
between versions 5 and 6 of the series, perhaps related to reworking

after fabc4ed200f9, server_unresponsive add a condition to check whether client
need to reconnect depending on server->lstrp. When client failed to reconnect
for some time and abort connection, server->lstrp is updated for the last time.
In the following scene, server->lstrp is too old. This cause next command
failure in re-negotiation rather than waiting for re-negotiation done.
1. mount -t cifs -o username=Everyone,echo_internal=10 //$server_ip/export /mnt

3. ls /mnt

6. ls # return EHOSTDOWN
If the interval between 5 and 6 is too small, 6 may trigger sending negotiation
request. Before backgrounding cifsd thread try to receive negotiation response
from server in cifs_readv_from_socket, server_unresponsive may trigger
cifs_reconnect which cause 6 to be failed:
ls thread

server->tcpStatus = CifsInNegotiate
compound_send_recv
wait_for_compound_request
ls thread
----------------
cifs_sync_mid_result return EAGAIN
smb2_negotiate return EHOSTDOWN
Though server->lstrp means last server response time, it is updated in
cifs_abort_connection and cifs_get_tcp_session. We can also update server->lstrp
before switching into CifsInNegotiate state to avoid failure in 6.

KVM: TDX: Exit to userspace for GetTdVmCallInfo

to allow userspace to provide information about the support of
TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API.
GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>,
<ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>,
<Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and
<Instruction.WRMSR>. They must be supported by VMM to support TDX guests.
For GetTdVmCallInfo
- When leaf (r12) to enumerate TDVMCALL functionality is set to 0,
successful execution indicates all GHCI base TDVMCALLs listed above are
supported.
Update the KVM TDX document with the set of the GHCI base APIs.
- When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it
indicates the TDX guest is querying the supported TDVMCALLs beyond
the GHCI base TDVMCALLs.
Exit to userspace to let userspace set the TDVMCALL sub-function bit(s)
accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s)
supported by itself when the TDVMCALLs don't need support from userspace
after returning from userspace and before entering guest. Currently, no
such TDVMCALLs implemented, KVM just sets the values returned from
userspace.

KVM: TDX: Handle TDG.VP.VMCALL<GetQuote>
Handle TDVMCALL for GetQuote to generate a TD-Quote.
GetQuote is a doorbell-like interface used by TDX guests to request VMM
to generate a TD-Quote signed by a service hosting TD-Quoting Enclave
operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in
a shared-memory area as parameter. Host VMM can access it and queue the
operation for a service hosting TD-Quoting enclave. When completed, the
Quote is returned via the same shared-memory area.
KVM only checks the GPA from the TDX guest has the shared-bit set and drops
the shared-bit before exiting to userspace to avoid bleeding the shared-bit
into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU)
and userspace VMM queues the operation asynchronously. KVM sets the return
code according to the 'ret' field set by userspace to notify the TDX guest
whether the request has been queued successfully or not. When the request
has been queued successfully, the TDX guest can poll the status field in
the shared-memory area to check whether the Quote generation is completed
or not. When completed, the generated Quote is returned via the same
buffer.
Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is
required to handle the KVM exit reason as the initial support for TDX,
by reentering KVM to ensure that the TDVMCALL is complete. While at it,
add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

KVM: TDX: Add new TDVMCALL status code for unsupported subfuncs
Add the new TDVMCALL status code TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED and
return it for unimplemented TDVMCALL subfunctions.
Returning TDVMCALL_STATUS_INVALID_OPERAND when a subfunction is not
implemented is vague because TDX guests can't tell the error is due to
the subfunction is not supported or an invalid input of the subfunction.
New GHCI spec adds TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED to avoid the
ambiguity. Use it instead of TDVMCALL_STATUS_INVALID_OPERAND.
Before the change, for common guest implementations, when a TDX guest
receives TDVMCALL_STATUS_INVALID_OPERAND, it has two cases:
1. Some operand is invalid. It could change the operand to another value
retry.
2. The subfunction is not supported.
For case 1, an invalid operand usually means the guest implementation bug.
Since the TDX guest can't tell which case is, the best practice for
handling TDVMCALL_STATUS_INVALID_OPERAND is stopping calling such leaf,
treating the failure as fatal if the TDVMCALL is essential or ignoring
it if the TDVMCALL is optional.
With this change, TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED could be sent to
old TDX guest that do not know about it, but it is expected that the
guest will make the same action as TDVMCALL_STATUS_INVALID_OPERAND.
Currently, no known TDX guest checks TDVMCALL_STATUS_INVALID_OPERAND
specifically; for example Linux just checks for success.

Merge tag 'net-6.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from wireless.
The ath12k fix to avoid FW crashes requires adding support for a
number of new FW commands so it's quite large in terms of LoC. The
rest is relatively small.
Current release - fix to a fix:
- ptp: fix breakage after ptp_vclock_in_use() rework
Current release - regressions:
- openvswitch: allocate struct ovs_pcpu_storage dynamically, static
allocation may exhaust module loader limit on smaller systems
Previous releases - regressions:
- tcp: fix tcp_packet_delayed() for peers with no selective ACK
support
Previous releases - always broken:
- wifi: ath12k: don't activate more links than firmware supports
- tcp: make sure sockets open via passive TFO have valid NAPI ID
- eth: bnxt_en: update MRU and RSS table of RSS contexts on queue
reset, prevent Rx queues from silently hanging after queue reset
- NFC: uart: set tty->disc_data only in success path"
