Remove pci_clear_master to simplify the code,
the bus-mastering is also cleared in do_pci_disable_device,
like this:
./drivers/pci/pci.c:2197
static void do_pci_disable_device(struct pci_dev *dev)
{
u16 pci_command;
pci_read_config_word(dev, PCI_COMMAND, &pci_command);
if (pci_command & PCI_COMMAND_MASTER) {
pci_command &= ~PCI_COMMAND_MASTER;
pci_write_config_word(dev, PCI_COMMAND, pci_command);
}
pcibios_disable_device(dev);
}.
And dev->is_busmaster is set to 0 in pci_disable_device.

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

As ntb_register_device() don't handle error of device_register(),
if ntb_register_device() returns error in pci_vntb_probe(), name of kobject
which is allocated in dev_set_name() called in device_add() is leaked.
As comment of device_add() says, it should call put_device() to drop the
reference count that was set in device_initialize()
when it fails, so the name can be freed in kobject_cleanup().

As the devm_kcalloc may return NULL pointer,
it should be better to add check for the return
value, as same as the others.

If device_register() returns error, the name allocated by
dev_set_name() need be freed. As comment of device_register()
says, it should use put_device() to give up the reference in
the error path. So fix this by calling put_device(), then the
name can be freed in kobject_cleanup(), and client_dev is freed
in ntb_transport_client_release().

Dave Airlie reports that gcc-13.1.1 has started complaining about some
of the workqueue code in 32-bit arm builds:
kernel/workqueue.c: In function ‘get_work_pwq’:
kernel/workqueue.c:713:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
713 | return (void *)(data & WORK_STRUCT_WQ_DATA_MASK);
| ^
[ ... a couple of other cases ... ]
and while it's not immediately clear exactly why gcc started complaining
about it now, I suspect it's some C23-induced enum type handlign fixup in
gcc-13 is the cause.
Whatever the reason for starting to complain, the code and data types
are indeed disgusting enough that the complaint is warranted.
The wq code ends up creating various "helper constants" (like that
WORK_STRUCT_WQ_DATA_MASK) using an enum type, which is all kinds of
confused. The mask needs to be 'unsigned long', not some unspecified
enum type.
To make matters worse, the actual "mask and cast to a pointer" is
repeated a couple of times, and the cast isn't even always done to the
right pointer, but - as the error case above - to a 'void *' with then
the compiler finishing the job.
That's now how we roll in the kernel.
So create the masks using the proper types rather than some ambiguous
enumeration, and use a nice helper that actually does the type
conversion in one well-defined place.
Incidentally, this magically makes clang generate better code. That,
admittedly, is really just a sign of clang having been seriously
confused before, and cleaning up the typing unconfuses the compiler too.

It's late but here are two bug fixes. Both fix problems which can be severe
but are very confined in scope. The risk to most use cases should be
minimal.
* Fix for an old bug which triggers if a cgroup subsystem is remounted to a
different hierarchy while someone is reading its cgroup.procs/tasks file.
The risk is pretty low given how seldom cgroup subsystems are moved across

Just like for sc7180 devices using the Chrome bootflow (AKA trogdor
and IDP), sc7280 devices using the Chrome bootflow also need their
firmware marked dma-coherent. On sc7280 this wasn't causing WiFi to
fail to startup, since WiFi works differently there. However, on
sc7280 devices we were still getting the message at bootup after
commit 7bd6680b47 ("Revert "Revert "arm64: dma: Drop cache

qcom_scm firmware:scm: Assign memory protection call failed -22

Trogdor devices use firmware backed by TF-A instead of Qualcomm's
normal TZ. On TF-A we end up mapping memory as cacheable.
Specifically, you can see in Trogdor's TF-A code [1] in
qti_sip_mem_assign() that we call qti_mmap_add_dynamic_region() with
MT_RO_DATA. This translates down to MT_MEMORY instead of
MT_NON_CACHEABLE or MT_DEVICE. Apparently Qualcomm's normal TZ
implementation maps the memory as non-cacheable.
Let's add the "dma-coherent" attribute to the SCM for trogdor.
Adding "dma-coherent" like this fixes WiFi on sc7180-trogdor
devices. WiFi was broken as of commit 7bd6680b47 ("Revert "Revert
"arm64: dma: Drop cache invalidation from
arch_dma_prep_coherent()"""). Specifically at bootup we'd get:
qcom_scm firmware:scm: Assign memory protection call failed -22
qcom_rmtfs_mem 94600000.memory: assign memory failed
qcom_rmtfs_mem: probe of 94600000.memory failed with error -22
From discussion on the mailing lists [2] and over IRC [3], it was
determined that we should always have been tagging the SCM as
dma-coherent on trogdor but that the old "invalidate" happened to make
things work most of the time. Tagging it properly like this is a much
more robust solution.

sc7180-idp is, for most intents and purposes, a trogdor device.
Specifically, sc7180-idp is designed to run the same style of firmware
as trogdor devices. This can be seen from the fact that IDP has the
same "Reserved memory changes" in its device tree that trogdor has.
Recently it was realized that we need to mark SCM as dma-coherent to
match what trogdor's style of firmware (based on TF-A) does [1]. That
means we need this dma-coherent tag on IDP as well.
Without this, on newer versions of Linux, specifically those with
commit 7bd6680b47 ("Revert "Revert "arm64: dma: Drop cache

We run into guest hang in edk2 firmware when KSM is kept as running on
the host. The edk2 firmware is waiting for status 0x80 from QEMU's pflash
device (TYPE_PFLASH_CFI01) during the operation of sector erasing or
buffered write. The status is returned by reading the memory region of
the pflash device and the read request should have been forwarded to QEMU
and emulated by it. Unfortunately, the read request is covered by an
illegal stage2 mapping when the guest hang issue occurs. The read request
is completed with QEMU bypassed and wrong status is fetched. The edk2
firmware runs into an infinite loop with the wrong status.
The illegal stage2 mapping is populated due to same page sharing by KSM
at (C) even the associated memory slot has been marked as invalid at (B)
when the memory slot is requested to be deleted. It's notable that the
active and inactive memory slots can't be swapped when we're in the middle
of kvm_mmu_notifier_change_pte() because kvm->mn_active_invalidate_count
is elevated, and kvm_swap_active_memslots() will busy loop until it reaches
to zero again. Besides, the swapping from the active to the inactive memory
slots is also avoided by holding &kvm->srcu in __kvm_handle_hva_range(),
corresponding to synchronize_srcu_expedited() in kvm_swap_active_memslots().

Fix the issue by skipping the invalid memory slot at (C) to avoid the
illegal stage2 mapping so that the read request for the pflash's status
is forwarded to QEMU and emulated by it. In this way, the correct pflash's
status can be returned from QEMU to break the infinite loop in the edk2
firmware.
We tried a git-bisect and the first problematic commit is cd4c718352 ("
KVM: arm64: Convert to the gfn-based MMU notifier callbacks"). With this,
clean_dcache_guest_page() is called after the memory slots are iterated
in kvm_mmu_notifier_change_pte(). clean_dcache_guest_page() is called
before the iteration on the memory slots before this commit. This change
literally enlarges the racy window between kvm_mmu_notifier_change_pte()
and memory slot removal so that we're able to reproduce the issue in a
practical test case. However, the issue exists since commit d5d8184d35
("KVM: ARM: Memory virtualization setup").

There was regression caused by a97699d1d6 ("btrfs: replace
map_lookup->stripe_len by BTRFS_STRIPE_LEN") and supposedly fixed by
a7299a18a1 ("btrfs: fix u32 overflows when left shifting stripe_nr").
To avoid code churn the fix was open coding the type casts but
unfortunately missed one which was still possible to hit [1].
The missing place was assignment of bioc->full_stripe_logical inside
btrfs_map_block().
Fix it by adding a helper that does the safe calculation of the offset
and use it everywhere even though it may not be strictly necessary due
to already using u64 types. This replaces all remaining
"<< BTRFS_STRIPE_LEN_SHIFT" calls.

Pablo Neira Ayuso says:
====================
Netfilter/IPVS fixes for net
This is v3, including a crash fix for patch 01/14.
The following patchset contains Netfilter/IPVS fixes for net:
1) Fix UDP segmentation with IPVS tunneled traffic, from Terin Stock.
2) Fix chain binding transaction logic, add a bound flag to rule
transactions. Remove incorrect logic in nft_data_hold() and
nft_data_release().
3) Add a NFT_TRANS_PREPARE_ERROR deactivate state to deal with releasing
the set/chain as a follow up to 1240eb93f0 ("netfilter: nf_tables:
incorrect error path handling with NFT_MSG_NEWRULE")
4) Drop map element references from preparation phase instead of
set destroy path, otherwise bogus EBUSY with transactions such as:
flush chain ip x y
delete chain ip x w
where chain ip x y contains jump/goto from set elements.
5) Pipapo set type does not regard generation mask from the walk
iteration.
6) Fix reference count underflow in set element reference to
stateful object.
7) Several patches to tighten the nf_tables API:
- disallow set element updates of bound anonymous set
- disallow unbound anonymous set/chain at the end of transaction.
- disallow updates of anonymous set.
- disallow timeout configuration for anonymous sets.
8) Fix module reference leak in chain updates.
9) Fix nfnetlink_osf module autoload.
10) Fix deletion of basechain when NFTA_CHAIN_HOOK is specified as
in iptables-nft.
This Netfilter batch is larger than usual at this stage, I am aware we
are fairly late in the -rc cycle, if you prefer to route them through
net-next, please let me know.

This reverts commit 1f86123b97 ("net: align SO_RCVMARK required
privileges with SO_MARK") because the reasoning in the commit message
is not really correct:
SO_RCVMARK is used for 'reading' incoming skb mark (via cmsg), as such
it is more equivalent to 'getsockopt(SO_MARK)' which has no priv check
and retrieves the socket mark, rather than 'setsockopt(SO_MARK) which
sets the socket mark and does require privs.
Additionally incoming skb->mark may already be visible if
sysctl_fwmark_reflect and/or sysctl_tcp_fwmark_accept are enabled.
Furthermore, it is easier to block the getsockopt via bpf
(either cgroup setsockopt hook, or via syscall filters)
then to unblock it if it requires CAP_NET_RAW/ADMIN.
On Android the socket mark is (among other things) used to store
the network identifier a socket is bound to. Setting it is privileged,
but retrieving it is not. We'd like unprivileged userspace to be able
to read the network id of incoming packets (where mark is set via
iptables [to be moved to bpf])...
An alternative would be to add another sysctl to control whether
setting SO_RCVMARK is privilged or not.
(or even a MASK of which bits in the mark can be exposed)
But this seems like over-engineering...
Note: This is a non-trivial revert, due to later merged commit e42c7beee7
("bpf: net: Consider has_current_bpf_ctx() when testing capable() in sk_setsockopt()")
which changed both 'ns_capable' into 'sockopt_ns_capable' calls.

When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.
If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.
Fix this by setting the neighbor's state to permanent in a couple of
tests, so that it is always valid.

Properly check for RX_DROP_UNUSABLE now that the new drop reason
infrastructure is used. Without this change, the comparison will always
be false as a more specific reason is given in the lower bits of result.
