s390/qeth: Fix vipa deletion
Change boolean parameter of function "qeth_l3_vipa_store" inside the
"qeth_l3_dev_vipa_del4_store" function from "true" to "false" because
"true" is used for adding a virtual ip address and "false" for deleting.

ARM64:
* Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the stage-2
fault path.
* Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.
* Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
* Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.
* Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
* Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.
* Ensure timer IRQs are consistently released in the init failure
paths.
* Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.
* Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.
RISC-V:
* Redirect AMO load/store misaligned traps to KVM guest
* Trap-n-emulate AIA in-kernel irqchip for KVM guest
* Svnapot support for KVM Guest
s390:
* New uvdevice secret API
* CMM selftest and fixes
* fix racy access to target CPU for diag 9c
x86:
* Fix missing/incorrect #GP checks on ENCLS
* Use standard mmu_notifier hooks for handling APIC access page
* Drop now unnecessary TR/TSS load after VM-Exit on AMD
* Print more descriptive information about the status of SEV and SEV-ES during
module load
* Add a test for splitting and reconstituting hugepages during and after
dirty logging
* Add support for CPU pinning in demand paging test
* Add support for AMD PerfMonV2, with a variety of cleanups and minor fixes
included along the way
* Add a "nx_huge_pages=never" option to effectively avoid creating NX hugepage
recovery threads (because nx_huge_pages=off can be toggled at runtime)
* Move handling of PAT out of MTRR code and dedup SVM+VMX code
* Fix output of PIC poll command emulation when there's an interrupt
* Add a maintainer's handbook to document KVM x86 processes, preferred coding
style, testing expectations, etc.

Networking changes for 6.5.
Core
----
- Rework the sendpage & splice implementations. Instead of feeding
data into sockets page by page extend sendmsg handlers to support
taking a reference on the data, controlled by a new flag called
MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
to invoke an additional callback instead of trying to predict what
the right combination of MORE/NOTLAST flags is.
Remove the MSG_SENDPAGE_NOTLAST flag completely.
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
- Enable socket busy polling with CONFIG_RT.
- Improve reliability and efficiency of reporting for ref_tracker.
- Auto-generate a user space C library for various Netlink families.
Protocols
---------
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2].
- Use per-VMA locking for "page-flipping" TCP receive zerocopy.
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags.
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative.
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
- Avoid waking up applications using TLS sockets until we have
a full record.
- Allow using kernel memory for protocol ioctl callbacks, paving
the way to issuing ioctls over io_uring.
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address.
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch.
- PPPoE: make number of hash bits configurable.
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API
----------
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out).
- Support configuring rate selection pins of SFP modules.
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines.
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer.
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio).
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message.
- Split devlink instance and devlink port operations.

Merge tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.
Core:
- Rework the sendpage & splice implementations
Instead of feeding data into sockets page by page extend sendmsg
handlers to support taking a reference on the data, controlled by a
new flag called MSG_SPLICE_PAGES
Rework the handling of unexpected-end-of-file to invoke an
additional callback instead of trying to predict what the right
combination of MORE/NOTLAST flags is
Remove the MSG_SENDPAGE_NOTLAST flag completely
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid
- Enable socket busy polling with CONFIG_RT
- Improve reliability and efficiency of reporting for ref_tracker
- Auto-generate a user space C library for various Netlink families
Protocols:
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2]
- Use per-VMA locking for "page-flipping" TCP receive zerocopy
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative
- Create a new MPTCP getsockopt to retrieve all info
(MPTCP_FULL_INFO)
- Avoid waking up applications using TLS sockets until we have a full
record
- Allow using kernel memory for protocol ioctl callbacks, paving the
way to issuing ioctls over io_uring
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch
- PPPoE: make number of hash bits configurable
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig)
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge)
- Support matching on Connectivity Fault Management (CFM) packets
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug
- HSR: don't enable promiscuous mode if device offloads the proto
- Support active scanning in IEEE 802.15.4
- Continue work on Multi-Link Operation for WiFi 7
BPF:
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used, or
in fact passing the verifier at all for complex programs,
especially those using open-coded iterators
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what the
output buffer *should* be, without writing anything
- Accept dynptr memory as memory arguments passed to helpers
- Add routing table ID to bpf_fib_lookup BPF helper
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only)
- Show target_{obj,btf}_id in tracing link fdinfo
- Addition of several new kfuncs (most of the names are
self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter:
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value
- Increase ip_vs_conn_tab_bits range for 64BIT builds
- Allow updating size of a set
- Improve NAT tuple selection when connection is closing
Driver API:
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out)
- Support configuring rate selection pins of SFP modules
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio)
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message
- Split devlink instance and devlink port operations
New hardware / drivers:
- Ethernet:
- Synopsys EMAC4 IP support (stmmac)
- Marvell 88E6361 8 port (5x1GE + 3x2.5GE) switches
- Marvell 88E6250 7 port switches

s390 updates for 6.5 merge window
- Fix the style of protected key API driver source: use x-mas tree for all local variable declarations. - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore. Both structures have a fixed size buffer, but with the support of ECC protected key these buffers are not big enough. Use dynamic buffers internally and transparently for userspace. - Add support for a new 'non CCA clear key token' with ECC clear keys supported: ECC P256, ECC P384, ECC P521, ECC ED25519 and ECC ED448. This makes it possible to derive a protected key from the ECC clear key input via PKEY_KBLOB2PROTK3 ioctl, while currently the only way to derive is via PCKMO instruction. - The s390 PMU of PAI crypto and extension 1 NNPA counters use atomic_t for reference counting. Replace this with the proper data type refcount_t. - Select ARCH_SUPPORTS_INT128, but limit this to clang for now, since gcc generates inefficient code, which may lead to stack overflows. - Replace one-element array with flexible-array member in struct vfio_ccw_parent and refactor the rest of the code accordingly. Also, prefer struct_size() over sizeof() open- coded versions. - Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether the system memory should be cleared or not once dumped. - Fix a hang when a user attempts to remove a VFIO-AP mediated device attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver callback to request a release of the device. - Fix calculation for R_390_GOTENT relocations for modules. - Allow any user space process with CAP_PERFMON capability read and display the CPU Measurement facility counter sets. - Rework large statically-defined per-CPU cpu_cf_events data structure and replace it with dynamically allocated structures created when a perf_event_open() system call is invoked or /dev/hwctr device is accessed. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZJsnCRccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8D+RAQCN5CYdql/X8kOMcs4jJvDHEZf8 5CHYfmT2SLNs+zWtLgD/f/C9XXv3El/0wMBvuWSZ+T1nw+imt2cz+FJ+Nor+UQg= =R7Dm -----END PGP SIGNATURE----- Merge tag 's390-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Fix the style of protected key API driver source: use x-mas tree for all local variable declarations - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore.

dax: enable dax fault handler to report VM_FAULT_HWPOISON
When multiple processes mmap() a dax file, then at some point, a process issues a 'load' and consumes a hwpoison, the process receives a SIGBUS with si_code = BUS_MCEERR_AR and with si_lsb set for the poison scope. Soon after, any other process issues a 'load' to the poisoned page (that is unmapped from the kernel side by memory_failure), it receives a SIGBUS with si_code = BUS_ADRERR and without valid si_lsb. This is confusing to user, and is different from page fault due to poison in RAM memory, also some helpful information is lost. Channel dax backend driver's poison detection to the filesystem such that instead of reporting VM_FAULT_SIGBUS, it could report VM_FAULT_HWPOISON. If user level block IO syscalls fail due to poison, the errno will be converted to EIO to maintain block API consistency.

s390/ctcm: Convert sprintf/snprintf to scnprintf
This LWN article explains the why scnprintf is preferred over snprintf in general https://lwn.net/Articles/69419/ Ie. snprintf() returns what *would* be the resulting length, while scnprintf() returns the actual length. Note that ctcm_print_statistics() writes the data into the kernel log and is therefore not suitable for sysfs_emit(). Observable behavior is not changed, as there may be dependencies.

s390/ism: Fix trying to free already-freed IRQ by repeated ism_dev_exit()
This patch prevents the system from crashing when unloading the ISM module.
How to reproduce: Attach an ISM device and execute 'rmmod ism'.
Error-Log:
- Trying to free already-free IRQ 0
- WARNING: CPU: 1 PID: 966 at kernel/irq/manage.c:1890 free_irq+0x140/0x540
After calling ism_dev_exit() for each ISM device in the exit routine,
pci_unregister_driver() will execute ism_remove() for each ISM device.
Because ism_remove() also calls ism_dev_exit(),
free_irq(pci_irq_vector(pdev, 0), ism) is called twice for each ISM
device. This results in a crash with the error
'Trying to free already-free IRQ'.
In the exit routine, it is enough to call pci_unregister_driver()
because it ensures that ism_dev_exit() is called once per
ISM device.

block: use the holder as indication for exclusive opens
The current interface for exclusive opens is rather confusing as it requires both the FMODE_EXCL flag and a holder. Remove the need to pass FMODE_EXCL and just key off the exclusive open off a non-NULL holder. For blkdev_put this requires adding the holder argument, which provides better debug checking that only the holder actually releases the hold, but at the same time allows removing the now superfluous mode argument.

Merge branch 'protected-key' into features
Harald Freudenberger says: =================== This patches do some cleanup and reorg of the pkey module code and extend the existing ioctl with supporting derivation of protected key material from clear key material for some ECC curves with the help of the PCKMO instruction. Please note that 'protected key' is a special type of key only available on s390. It is similar to an secure key which is encrypted by a master key sitting inside an HSM. In contrast to secure keys a protected key is encrypted by a random key located in a hidden firmware memory accessible by the CPU and thus much faster but less secure. =================== The merged updates are: - Fix the style of protected key API driver source: use x-mas tree for all local variable declarations. - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore. Both structures have a fixed size buffer, but with the support of ECC protected key these buffers are not big enough. Use dynamic buffers internally and transparently for userspace. - Add support for a new 'non CCA clear key token' with ECC clear keys supported: ECC P256, ECC P384, ECC P521, ECC ED25519 and ECC ED448. This makes it possible to derive a protected key from the ECC clear key input via PKEY_KBLOB2PROTK3 ioctl, while currently the only way to derive is via PCKMO instruction.

s390/pkey: add support for ecc clear key
Add support for a new 'non CCA clear key token' with these ECC clear keys supported: - ECC P256 - ECC P384 - ECC P521 - ECC ED25519 - ECC ED448 This makes it possible to derive a protected key from this ECC clear key input via PKEY_KBLOB2PROTK3 ioctl. As of now the only way to derive protected keys from these clear key tokens is via PCKMO instruction. For AES keys an alternate path via creating a secure key from the clear key and then derive a protected key from the secure key exists. This alternate path is not implemented for ECC keys as it would require to rearrange and maybe recalculate the clear key material for input to derive an CCA or EP11 ECC secure key.

s390/pkey: do not use struct pkey_protkey
This is an internal rework of the pkey code to not use the struct pkey_protkey internal any more. This struct has a hard coded protected key buffer with MAXPROTKEYSIZE = 64 bytes. However, with support for ECC protected key, this limit is too short and thus this patch reworks all the internal code to use the triple u8 *protkey, u32 protkeylen, u32 protkeytype instead. So the ioctl which still has to deal with this struct coming from userspace and/or provided to userspace invoke all the internal functions now with the triple instead of passing a pointer to struct pkey_protkey. Also the struct pkey_clrkey has been internally replaced in a similar way. This struct also has a hard coded clear key buffer of MAXCLRKEYSIZE = 32 bytes and thus is not usable with e.g. ECC clear key material. This is a transparent rework for userspace applications using the pkey API. The internal kernel API used by the PAES crypto ciphers has been adapted to this change to make it possible to provide ECC protected keys via this interface in the future.

s390/zcore: conditionally clear memory on reipl
Currently zcore_reipl_write() always use DIAG308_LOAD_CLEAR to ipl the system (used by ngdump and zfcpdump to ipl the original kernel after dumping). Instead of 'always clear' check OS_INFO_FLAG_REIPL_CLEAR flag and use either LOAD_CLEAR or LOAD_NORMAL diag308 subcode accordingly. For that read os_info and check for the valid os_info flags entry in zcore_reipl_init(). Do not return error on failure (e.g. os_info checksum error) in order to continue dump processing, considering that os_info could be corrupted on the panicked system.

s390/ism: Set DMA coherent mask
A future change will convert the DMA API implementation from the architecture specific arch/s390/pci/pci_dma.c to using the common code drivers/iommu/dma-iommu.c which the utilizes the same IOMMU hardware through the s390-iommu driver. Unlike the s390 specific DMA API this requires devices to correctly set the coherent mask to be allowed to use IOVAs >2^32 in dma_alloc_coherent(). This was however not done for ISM devices. ISM requires such addresses since currently the DMA aperture for PCI devices starts at 2^32 and all calls to dma_alloc_coherent() would thus fail.

Merge patch series "Use block pr_ops in LIO"
Mike Christie <michael.christie@oracle.com> says: The patches in this thread allow us to use the block pr_ops with LIO's target_core_iblock module to support cluster applications in VMs. They were built over Linus's tree. They also apply over linux-next and Martin's tree and Jens's trees. Currently, to use windows clustering or linux clustering (pacemaker + cluster labs scsi fence agents) in VMs with LIO and vhost-scsi, you have to use tcmu or pscsi or use a cluster aware FS/framework for the LIO pr file. Setting up a cluster FS/framework is pain and waste when your real backend device is already a distributed device, and pscsi and tcmu are nice for specific use cases, but iblock gives you the best performance and allows you to use stacked devices like dm-multipath. So these patches allow iblock to work like pscsi/tcmu where they can pass a PR command to the backend module. And then iblock will use the pr_ops to pass the PR command to the real devices similar to what we do for unmap today. The patches are separated in the following groups: Patch 1 - 2: - Add block layer callouts for reading reservations and rename reservation error code. Patch 3 - 5: - SCSI support for new callouts. Patch 6: - DM support for new callouts. Patch 7 - 13: - NVMe support for new callouts. Patch 14 - 18: - LIO support for new callouts. This patchset has been tested with the libiscsi PGR ops and with window's failover cluster verification test. Note that for scsi backend devices we need this patchset: https://lore.kernel.org/linux-scsi/20230123221046.125483-1-michael.christie@oracle.com/T/#m4834a643ffb5bac2529d65d40906d3cfbdd9b1b7 to handle UAs. To reduce the size of this patchset that's being done separately to make reviewing easier. And to make merging easier this patchset and the one above do not have any conflicts so can be merged in different trees.

s390/dasd: fix command reject error on ESE devices
Formatting a thin-provisioned (ESE) device that is part of a PPRC copy
relation might fail with the following error:
dasd-eckd 0.0.f500: An error occurred in the DASD device driver, reason=09
[...]
24 Byte: 0 MSG 4, no MSGb to SYSOP
During format of an ESE disk the Release Allocated Space command is used.
A bit in the payload of the command is set that is not allowed to be set
for devices in a copy relation. This bit is set to allow the partial
release of an extent.
Check for the existence of a copy relation before setting the respective
bit.

s390/qdio: fix do_sqbs() inline assembly constraint
Use "a" constraint instead of "d" constraint to pass the state parameter to
the do_sqbs() inline assembly. This prevents that general purpose register
zero is used for the state parameter.
If the compiler would select general purpose register zero this would be
problematic for the used instruction in rsy format: the register used for
the state parameter is a base register. If the base register is general
purpose register zero the contents of the register are unexpectedly ignored
when the instruction is executed.
This only applies to z/VM guests using QIOASSIST with dedicated (pass through)
QDIO-based devices such as FCP [zfcp driver] as well as real OSA or
HiperSockets [qeth driver].
A possible symptom for this case using zfcp is the following repeating kernel
message pattern:
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: qdio: ZFCP on SC <sc> using AI:1 QEBSM:1 PRI:1 TDD:1 SIGA: W
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
Each of the qdio problem message can be accompanied by the following entries
for the affected subchannel <sc> in
/sys/kernel/debug/s390dbf/qdio_error/hex_ascii for zfcp or qeth:
<sc> ccq: 69....
<sc> SQBS ERROR.
