VFIO updates for v6.7
- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
which allows both larger device image sizes for migration, beyond
the previous 4GB limit, and also read-ahead support for improved
migration performance. (Yishai Hadas)
- A new bus master control interface for the CDX bus driver where
there is no in-band mechanism to toggle device DMA as there is
through config space on PCI devices. (Nipun Gupta)
- Add explicit alignment directives to vfio data structures to
reduce the chance of breaking 32-bit userspace. In most cases
this is transparent and the remaining cases where data structures
are padded work within the existing rules for extending data
structures within vfio. (Stefan Hajnoczi)
- Resolve a bug in the cdx bus driver noted when compiled with clang
where missing parenthesis result in the wrong operation.
(Nathan Chancellor)
- Resolve errors reported by smatch for a function when dealing
with invalid inputs. (Alex Williamson)
- Add migration support to the mtty vfio/mdev sample driver for
testing and integration purposes, allowing CI of migration without
specific hardware requirements. Also resolve many of the short-
comings of this driver relative to implementation of the vfio
interrupt ioctl along the way. (Alex Williamson)

Merge tag 'io_uring-futex-2023-10-30' of git://git.kernel.dk/linux
Pull io_uring futex support from Jens Axboe:
"This adds support for using futexes through io_uring - first futex
wake and wait, and then the vectored variant of waiting, futex waitv.
For both wait/wake/waitv, we support the bitset variant, as the
'normal' variants can be easily implemented on top of that.
PI and requeue are not supported through io_uring, just the above
mentioned parts. This may change in the future, but in the spirit of
keeping this small (and based on what people have been asking for),
this is what we currently have.
Wake support is pretty straight forward, most of the thought has gone
into the wait side to avoid needing to offload wait operations to a
blocking context. Instead, we rely on the usual callbacks to retry and
post a completion event, when appropriate.
As far as I can recall, the first request for futex support with
io_uring came from Andres Freund, working on postgres. His aio rework
of postgres was one of the early adopters of io_uring, and futex
support was a natural extension for that. This is relevant from both a
usability point of view, as well as for effiency and performance. In
Andres's words, for the former:
Futex wait support in io_uring makes it a lot easier to avoid
deadlocks in concurrent programs that have their own buffer pool:
Obviously pages in the application buffer pool have to be locked
during IO. If the initiator of IO A needs to wait for a held lock
B, the holder of lock B might wait for the IO A to complete. The
ability to wait for a lock and IO completions at the same time
provides an efficient way to avoid such deadlocks
and in terms of effiency, even without unlocking the full potential
yet, Andres says:
Futex wake support in io_uring is useful because it allows for more
efficient directed wakeups. For some "locks" postgres has queues
implemented in userspace, with wakeup logic that cannot easily be
implemented with FUTEX_WAKE_BITSET on a single "futex word"
(imagine waiting for journal flushes to have completed up to a
certain point).
Thus a "lock release" sometimes need to wake up many processes in a
row. A quick-and-dirty conversion to doing these wakeups via
io_uring lead to a 3% throughput increase, with 12% fewer context
switches, albeit in a fairly extreme workload"
* tag 'io_uring-futex-2023-10-30' of git://git.kernel.dk/linux:
io_uring: add support for vectored futex waits
futex: make the vectored futex operations available
futex: make futex_parse_waitv() available as a helper
futex: add wake_data to struct futex_q
io_uring: add support for futex wake and wait
futex: abstract out a __futex_wake_mark() helper
futex: factor out the futex wake handling

Networking changes for 6.7.
Core & protocols
----------------
- Support usec resolution of TCP timestamps, enabled selectively by
a route attribute.
- Defer regular TCP ACK while processing socket backlog, try to send
a cumulative ACK at the end. Increase single TCP flow performance
on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).
- The Fair Queuing (FQ) packet scheduler:
- add built-in 3 band prio / WRR scheduling
- support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
- improve inactive flow reporting
- optimize the layout of structures for better cache locality
- Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
replacement for the old MD5 option.
- Add more retransmission timeout (RTO) related statistics to TCP_INFO.
- Support sending fragmented skbs over vsock sockets.
- Make sure we send SIGPIPE for vsock sockets if socket was shutdown().
- Add sysctl for ignoring lower limit on lifetime in Router
Advertisement PIO, based on an in-progress IETF draft.
- Add sysctl to control activation of TCP ping-pong mode.
- Add sysctl to make connection timeout in MPTCP configurable.
- Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
limit the number of wakeups.
- Support netlink GET for MDB (multicast forwarding), allowing user
space to request a single MDB entry instead of dumping the entire
table.
- Support selective FDB flushing in the VXLAN tunnel driver.
- Allow limiting learned FDB entries in bridges, prevent OOM attacks.
- Allow controlling via configfs netconsole targets which were created
via the kernel cmdline at boot, rather than via configfs at runtime.
- Support multiple PTP timestamp event queue readers with different
filters.
- MCTP over I3C.
BPF
---
- Add new veth-like netdevice where BPF program defines the logic
of the xmit routine. It can operate in L3 and L2 mode.
- Support exceptions - allow asserting conditions which should
never be true but are hard for the verifier to infer.
With some extra flexibility around handling of the exit / failure.
https://lwn.net/Articles/938435/
- Add support for local per-cpu kptr, allow allocating and storing
per-cpu objects in maps. Access to those objects operates on
the value for the current CPU. This allows to deprecate local
one-off implementations of per-CPU storage like
BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.
- Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
for systemd to re-implement the LogNamespace feature which allows
running multiple instances of systemd-journald to process the logs
of different services.
- Enable open-coded task_vma iteration, after maple tree conversion
made it hard to directly walk VMAs in tracing programs.
- Add open-coded task, css_task and css iterator support.
One of the use cases is customizable OOM victim selection via BPF.
- Allow source address selection with bpf_*_fib_lookup().
- Add ability to pin BPF timer to the current CPU.
- Prevent creation of infinite loops by combining tail calls and
fentry/fexit programs.
- Add missed stats for kprobes to retrieve the number of missed kprobe
executions and subsequent executions of BPF programs.
- Inherit system settings for CPU security mitigations.
- Add BPF v4 CPU instruction support for arm32 and s390x.
Changes to common code
----------------------
- overflow: add DEFINE_FLEX() for on-stack definition of structs
with flexible array members.
- Process doc update with more guidance for reviewers.
Driver API
----------
- Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
mutex in most places and remove a lot of smaller locks.
- Create a common DPLL configuration API. Allow configuring
and querying state of PLL circuits used for clock syntonization,
in network time distribution.
- Unify fragmented and full page allocation APIs in page pool code.
Let drivers be ignorant of PAGE_SIZE.
- Rework PHY state machine to avoid races with calls to phy_stop().
- Notify DSA drivers of MAC address changes on user ports, improve
correctness of offloads which depend on matching port MAC addresses.
- Allow antenna control on injected WiFi frames.
- Reduce the number of variants of napi_schedule().
- Simplify error handling when composing devlink health messages.
Misc
----
- A lot of KCSAN data race "fixes", from Eric.
- A lot of __counted_by() annotations, from Kees.
- A lot of strncpy -> strscpy and printf format fixes.
- Replace master/slave terminology with conduit/user in DSA drivers.
- Handful of KUnit tests for netdev and WiFi core.

Traditionally linkers only did this for .bss and it was always the last segment. As a result, the kernel only handled this case when it was the last segment. We've had two recent cases where linkers were trying to use these kinds of segments for other reasons, and the were in the middle of the segment list. There was no good reason for the kernel not to support this, and the refactor actually ends up making things more readable too. - Enable namespaced binfmt_misc Christian Brauner has made it possible to use binfmt_misc with mount namespaces.

Locking changes in this cycle are:
- Futex improvements:
- Add the 'futex2' syscall ABI, which is an attempt to get away from the
multiplex syscall and adds a little room for extentions, while lifting
some limitations.
- Fix futex PI recursive rt_mutex waiter state bug
- Fix inter-process shared futexes on no-MMU systems
- Use folios instead of pages
- Micro-optimizations of locking primitives:
- Improve arch_spin_value_unlocked() on asm-generic ticket spinlock
architectures, to improve lockref code generation.
- Improve the x86-32 lockref_get_not_zero() main loop by adding
build-time CMPXCHG8B support detection for the relevant lockref code,
and by better interfacing the CMPXCHG8B assembly code with the compiler.
- Introduce arch_sync_try_cmpxchg() on x86 to improve sync_try_cmpxchg()
code generation. Convert some sync_cmpxchg() users to sync_try_cmpxchg().

Pull btrfs updates from David Sterba:
"New features:
- raid-stripe-tree
New tree for logical file extent mapping where the physical mapping
may not match on multiple devices. This is now used in zoned mode
to implement RAID0/RAID1* profiles, but can be used in non-zoned
mode as well. The support for RAID56 is in development and will
eventually fix the problems with the current implementation. This
is a backward incompatible feature and has to be enabled at mkfs
time.
- simple quota accounting (squota)
A simplified mode of qgroup that accounts all space on the initial
extent owners (a subvolume), the snapshots are then cheap to create
and delete. The deletion of snapshots in fully accounting qgroups
is a known CPU/IO performance bottleneck.
The squota is not suitable for the general use case but works well
for containers where the original subvolume exists for the whole
time. This is a backward incompatible feature as it needs extending
some structures, but can be enabled on an existing filesystem.
- temporary filesystem fsid (temp_fsid)
The fsid identifies a filesystem and is hard coded in the
structures, which disallows mounting the same fsid found on
different devices.
For a single device filesystem this is not strictly necessary, a
new temporary fsid can be generated on mount e.g. after a device is
cloned. This will be used by Steam Deck for root partition A/B
testing, or can be used for VM root images.
Other user visible changes:
- filesystems with partially finished metadata_uuid conversion cannot
be mounted anymore and the uuid fixup has to be done by btrfs-progs
(btrfstune).
Performance improvements:
- reduce reservations for checksum deletions (with enabled free space
tree by factor of 4), on a sample workload on file with many
extents the deletion time decreased by 12%
- make extent state merges more efficient during insertions, reduce
rb-tree iterations (run time of critical functions reduced by 5%)
Core changes:
- the integrity check functionality has been removed, this was a
debugging feature and removal does not affect other integrity
checks like checksums or tree-checker
- space reservation changes:
- more efficient delayed ref reservations, this avoids building up
too much work or overusing or exhausting the global block
reserve in some situations
- move delayed refs reservation to the transaction start time,
this prevents some ENOSPC corner cases related to exhaustion of
global reserve
- improvements in reducing excessive reservations for block group
items
- adjust overcommit logic in near full situations, account for one
more chunk to eventually allocate metadata chunk, this is mostly
relevant for small filesystems (<10GiB)
- single device filesystems are scanned but not registered (except
seed devices), this allows temp_fsid to work
- qgroup iterations do not need GFP_ATOMIC allocations anymore
- cleanups, refactoring, reduced data structure size, function
parameter simplifications, error handling fixes"

fscrypt updates for 6.7
This update adds support for configuring the crypto data unit size (i.e. the granularity of file contents encryption) to be less than the filesystem block size. This can allow users to use inline encryption hardware in some cases when it wouldn't otherwise be possible.

NFSD 6.7 Release Notes
This release completes the SunRPC thread scheduler work that was begun in v6.6. The scheduler can now find an svc thread to wake in constant time and without a list walk. Thanks again to Neil Brown for this overhaul. Lorenzo Bianconi contributed infrastructure for a netlink-based NFSD control plane. The long-term plan is to provide the same functionality as found in /proc/fs/nfsd, plus some interesting additions, and then migrate the NFSD user space utilities to netlink. A long series to overhaul NFSD's NFSv4 operation encoding was applied in this release. The goals are to bring this family of encoding functions in line with the matching NFSv4 decoding functions and with the NFSv2 and NFSv3 XDR functions, preparing the way for better memory safety and maintainability. A further improvement to NFSD's write delegation support was contributed by Dai Ngo. This adds a CB_GETATTR callback, enabling the server to retrieve cached size and mtime data from clients holding write delegations. If the server can retrieve this information, it does not have to recall the delegation in some cases. The usual panoply of bug fixes and minor improvements round out this release. As always I am grateful to all contributors, reviewers, and testers. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmU5IuoACgkQM2qzM29m f5eVsg//bVp8S93ci/oDlKfzOwH2fO5e5rna91wrDpJxkd51h6KTx55dSRG5sjAZ EywIVOann6xCtsixAPyff5Cweg2dWvzQRsy1ZnvWQ1qZBzD5KAJY5LPkeSFUCKBo Zani/qTOYbxzgFMjZx+yDSXDPKG68WYZBQK59SI7mURu4SYdk8aRyNY8mjHfr0Vh Aqrcny4oVtXV4sL5P5G/2FUW7WKT3olA3jSYlRRNMhbs2qpEemRCCrspOEMMad+b t1+ZCg+U27PMranvOJnof4RU7peZbaxDWA0gyiUbivVXVtZn9uOs0ffhktkvechL ePc33dqdp2ITdKIPA6JlaRv5WflKXQw0YYM9Kv5mcR4A2el7owL4f/pMlPhtbYwJ IOJv15KdKVN979G2e6WMYiKK+iHfaUUguhMEXnfnGoAajHOZNQiUEo3iFQAD7LDc DvMF8d9QqYmB9IW8FOYaRRfZGJOQHf3TL79Nd08z/bn5swvlvfj77leux9Sb+0/m Luk2Xvz2AJVSXE31wzabaGHkizN+BtH+e4MMbXUHBPW5jE9v7XOnEUFr4UdZyr9P Gl87A7NcrzNjJWT5TrnzM4sOslNsx46Aeg+VuNt2fSRn2dm6iBu2B8s0N4imx6dV PX1y9VSLq5WRhjrFZ1qeiZdsuTaQtrEiNDoRIQR6nCJPAV80iFk= =B4wJ -----END PGP SIGNATURE----- Merge tag 'nfsd-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "This release completes the SunRPC thread scheduler work that was begun in v6.6.

net/tcp: Allow asynchronous delete for TCP-AO keys (MKTs)
Delete becomes very, very fast - almost free, but after setsockopt() syscall returns, the key is still alive until next RCU grace period. Which is fine for listen sockets as userspace needs to be aware of setsockopt(TCP_AO) and accept() race and resolve it with verification by getsockopt() after TCP connection was accepted. The benchmark results (on non-loaded box, worse with more RCU work pending): > ok 33 Worst case delete 16384 keys: min=5ms max=10ms mean=6.93904ms stddev=0.263421 > ok 34 Add a new key 16384 keys: min=1ms max=4ms mean=2.17751ms stddev=0.147564 > ok 35 Remove random-search 16384 keys: min=5ms max=10ms mean=6.50243ms stddev=0.254999 > ok 36 Remove async 16384 keys: min=0ms max=0ms mean=0.0296107ms stddev=0.0172078 Co-developed-by: Francesco Ruggeri <fruggeri@arista.com> Signed-off-by: Francesco Ruggeri <fruggeri@arista.com> Co-developed-by: Salam Noureddine <noureddine@arista.com> Signed-off-by: Salam Noureddine <noureddine@arista.com> Signed-off-by: Dmitry Safonov <dima@arista.com> Acked-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.

net/tcp: Add TCP-AO getsockopt()s
Introduce getsockopt(TCP_AO_GET_KEYS) that lets a user get TCP-AO keys and their properties from a socket. The user can provide a filter to match the specific key to be dumped or ::get_all = 1 may be used to dump all keys in one syscall. Add another getsockopt(TCP_AO_INFO) for providing per-socket/per-ao_info stats: packet counters, Current_key/RNext_key and flags like ::ao_required and ::accept_icmps.

net/tcp: Ignore specific ICMPs for TCP-AO connections
Similarly to IPsec, RFC5925 prescribes: ">> A TCP-AO implementation MUST default to ignore incoming ICMPv4 messages of Type 3 (destination unreachable), Codes 2-4 (protocol unreachable, port unreachable, and fragmentation needed -- ’hard errors’), and ICMPv6 Type 1 (destination unreachable), Code 1 (administratively prohibited) and Code 4 (port unreachable) intended for connections in synchronized states (ESTABLISHED, FIN-WAIT-1, FIN- WAIT-2, CLOSE-WAIT, CLOSING, LAST-ACK, TIME-WAIT) that match MKTs."

net/tcp: Introduce TCP_AO setsockopt()s
Add 3 setsockopt()s: 1. TCP_AO_ADD_KEY to add a new Master Key Tuple (MKT) on a socket 2. TCP_AO_DEL_KEY to delete present MKT from a socket 3. TCP_AO_INFO to change flags, Current_key/RNext_key on a TCP-AO sk Userspace has to introduce keys on every socket it wants to use TCP-AO option on, similarly to TCP_MD5SIG/TCP_MD5SIG_EXT. RFC5925 prohibits definition of MKTs that would match the same peer, so do sanity checks on the data provided by userspace. Be as conservative as possible, including refusal of defining MKT on an established connection with no AO, removing the key in-use and etc. (1) and (2) are to be used by userspace key manager to add/remove keys. (3) main purpose is to set RNext_key, which (as prescribed by RFC5925) is the KeyID that will be requested in TCP-AO header from the peer to sign their segments with.

netkit, bpf: Add bpf programmable net device
This work adds a new, minimal BPF-programmable device called "netkit"
(former PoC code-name "meta") we recently presented at LSF/MM/BPF. The
core idea is that BPF programs are executed within the drivers xmit routine
and therefore e.g. in case of containers/Pods moving BPF processing closer
to the source.
One of the goals was that in case of Pod egress traffic, this allows to
move BPF programs from hostns tcx ingress into the device itself, providing
earlier drop or forward mechanisms, for example, if the BPF program
determines that the skb must be sent out of the node, then a redirect to
the physical device can take place directly without going through per-CPU
backlog queue. This helps to shift processing for such traffic from softirq
to process context, leading to better scheduling decisions/performance (see
measurements in the slides).
In this initial version, the netkit device ships as a pair, but we plan to
extend this further so it can also operate in single device mode. The pair
comes with a primary and a peer device. Only the primary device, typically
residing in hostns, can manage BPF programs for itself and its peer. The
peer device is designated for containers/Pods and cannot attach/detach
BPF programs. Upon the device creation, the user can set the default policy
to 'pass' or 'drop' for the case when no BPF program is attached.
Additionally, the device can be operated in L3 (default) or L2 mode. The
management of BPF programs is done via bpf_mprog, so that multi-attach is
supported right from the beginning with similar API and dependency controls
as tcx. For details on the latter see commit

net: mptcp: convert netlink from small_ops to ops
in the current MPTCP control plane, all operations use a netlink attribute of the same type "MPTCP_PM_ATTR". However, add/del/get/flush operations only parse the first element in the message _ the one that describes MPTCP endpoints (that was named MPTCP_PM_ATTR_ADDR and mostly used in ADD_ADDR operations _ probably the similarity of "attr", "addr" and "add" might cause some confusion to human readers). Convert MPTCP from 'small_ops' to 'ops', thus allowing different attributes for each single operation, hopefully makes all this clearer to human readers. - use a separate attribute set for add/del/get/flush address operation, binary compatible with the existing one, to store the endpoint address. MPTCP_PM_ENDPOINT_ADDR is added to the uAPI (with the same value as MPTCP_PM_ATTR_ADDR) for these operations. - convert mptcp_pm_ops[] and add policy files accordingly. this prepares MPTCP control plane to be described as YAML spec.

drm/fourcc: Add NV20 and NV30 YUV formats
DRM_FORMAT_NV20 and DRM_FORMAT_NV30 formats is the 2x1 and non-subsampled variant of NV15, a 10-bit 2-plane YUV format that has no padding between components. Instead, luminance and chrominance samples are grouped into 4s so that each group is packed into an integer number of bytes: YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes The '20' and '30' suffix refers to the optimum effective bits per pixel which is achieved when the total number of luminance samples is a multiple of 4.

net: fix IPSTATS_MIB_OUTPKGS increment in OutForwDatagrams.
Reproduce environment:
network with 3 VM linuxs is connected as below:
VM1<---->VM2(latest kernel 6.5.0-rc7)<---->VM3
VM1: eth0 ip: 192.168.122.207 MTU 1500
VM2: eth0 ip: 192.168.122.208, eth1 ip: 192.168.123.224 MTU 1500
VM3: eth0 ip: 192.168.123.240 MTU 1500
Reproduce:
VM1 send 1400 bytes UDP data to VM3 using tools scapy with flags=0.
scapy command:
send(IP(dst="192.168.123.240",flags=0)/UDP()/str('0'*1400),count=1,
inter=1.000000)
Result:

"ForwDatagrams" increase from 4 to 5 and "OutRequests" also increase
from 7 to 8.
Issue description and patch:
IPSTATS_MIB_OUTPKTS("OutRequests") is counted with IPSTATS_MIB_OUTOCTETS
("OutOctets") in ip_finish_output2().
According to RFC 4293, it is "OutOctets" counted with "OutTransmits" but
not "OutRequests". "OutRequests" does not include any datagrams counted
in "ForwDatagrams".
ipSystemStatsOutOctets OBJECT-TYPE
DESCRIPTION
"The total number of octets in IP datagrams delivered to the
lower layers for transmission. Octets from datagrams
counted in ipIfStatsOutTransmits MUST be counted here.
ipSystemStatsOutRequests OBJECT-TYPE
DESCRIPTION
"The total number of IP datagrams that local IP user-
protocols (including ICMP) supplied to IP in requests for
transmission. Note that this counter does not include any
datagrams counted in ipSystemStatsOutForwDatagrams.
So do patch to define IPSTATS_MIB_OUTPKTS to "OutTransmits" and add
IPSTATS_MIB_OUTREQUESTS for "OutRequests".
Add IPSTATS_MIB_OUTREQUESTS counter in __ip_local_out() for ipv4 and add
IPSTATS_MIB_OUT counter in ip6_finish_output2() for ipv6.
Test result with patch:
Before IP data is sent.

netlink: add variable-length / auto integers
We currently push everyone to use padding to align 64b values in netlink. Un-padded nla_put_u64() doesn't even exist any more. The story behind this possibly start with this thread: https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/ where DaveM was concerned about the alignment of a structure containing 64b stats. If user space tries to access such struct directly: struct some_stats *stats = nla_data(attr); printf("A: %llu", stats->a); lack of alignment may become problematic for some architectures. These days we most often put every single member in a separate attribute, meaning that the code above would use a helper like nla_get_u64(), which can deal with alignment internally. Even for arches which don't have good unaligned access - access aligned to 4B should be pretty efficient. Kernel and well known libraries deal with unaligned input already. Padded 64b is quite space-inefficient (64b + pad means at worst 16B per attr vs 32b which takes 8B). It is also more typing: if (nla_put_u64_pad(rsp, NETDEV_A_SOMETHING_SOMETHING, value, NETDEV_A_SOMETHING_PAD)) Create a new attribute type which will use 32 bits at netlink level if value is small enough (probably most of the time?), and (4B-aligned) 64 bits otherwise. Kernel API is just: if (nla_put_uint(rsp, NETDEV_A_SOMETHING_SOMETHING, value)) Calling this new type "just" sint / uint with no specific size will hopefully also make people more comfortable with using it. Currently telling people "don't use u8, you may need the bits, and netlink will round up to 4B, anyway" is the #1 comment we give to newcomers. In terms of netlink layout it looks like this: 0 4 8 12 16 32b: [nlattr][ u32 ] 64b: [ pad ][nlattr][ u64 ] uint(32) [nlattr][ u32 ] uint(64) [nlattr][ u64 ] Signed-off-by: Jakub Kicinski <kuba@kernel.org> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

io_uring/cmd: Introduce SOCKET_URING_OP_SETSOCKOPT
Add initial support for SOCKET_URING_OP_SETSOCKOPT. This new command is similar to setsockopt. This implementation leverages the function do_sock_setsockopt(), which is shared with the setsockopt() system call path. Important to say that userspace needs to keep the pointer's memory alive until the operation is completed. I.e, the memory could not be deallocated before the CQE is returned to userspace.

io_uring/cmd: Introduce SOCKET_URING_OP_GETSOCKOPT
Add support for getsockopt command (SOCKET_URING_OP_GETSOCKOPT), where level is SOL_SOCKET. This is leveraging the sockptr_t infrastructure, where a sockptr_t is either userspace or kernel space, and handled as such. Differently from the getsockopt(2), the optlen field is not a userspace pointers. In getsockopt(2), userspace provides optlen pointer, which is overwritten by the kernel. In this implementation, userspace passes a u32, and the new value is returned in cqe->res. I.e., optlen is not a pointer.

net: bridge: Add netlink knobs for number / max learned FDB entries
The previous patch added accounting and a limit for the number of
dynamically learned FDB entries per bridge. However it did not provide
means to actually configure those bounds or read back the count. This
patch does that.
Two new netlink attributes are added for the accounting and limit of
dynamically learned FDB entries:
- IFLA_BR_FDB_N_LEARNED (RO) for the number of entries accounted for
a single bridge.
- IFLA_BR_FDB_MAX_LEARNED (RW) for the configured limit of entries for
the bridge.
The new attributes are used like this:
# ip link add name br up type bridge fdb_max_learned 256
# ip link add name v1 up master br type veth peer v2
# ip link set up dev v2
# mausezahn -a rand -c 1024 v2
0.01 seconds (90877 packets per second
# bridge fdb | grep -v permanent | wc -l
256
# ip -d link show dev br
13: br: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 [...]

This tag contains habanalabs driver changes for v6.7.
The notable changes are:
- uAPI changes:
- Expose tsc clock sampling to better sync clock information in profiler.
- Enhance engine error reporting in the info ioctl.
- Block access to the eventfd operations through the control device.
- Disable the option of the user to register multiple times with the same
offset for timestamp dump by the driver. If a user wants to use the same
offset in the timestamp buffer for different interrupt, it needs to first
de-register the offset.
- When exporting dma-buf (for p2p), force the user to specify size/offset
in multiples of PAGE_SIZE. This is instead of the driver doing the
rounding to PAGE_SIZE, which has caused the driver to map more memory
than was intended by the user.
- New features and improvements:
- Complete the move of the driver to the accel subsystem by removing the
custom habanalabs class and major and registering to accel subsystem.
- Move the firmware interface files to include/linux/habanalabs. This is
a pre-requisite for upstreaming the NIC drivers of Gaudi (as they need to
include those files).
- Perform device hard-reset upon PCIe AXI drain event to prevent the failure
from cascading to different IP blocks in the SoC. In secured environments,
this is done automatically by the firmware.
- Print device name when it is removed for better debuggability.
- Add support for trace of dma map sgtable operations.
- Optimize handling of user interrupts by splitting the interrupts to two
lists. One list for fast handling and second list for handling with
timestamp recording, which is slower.
- Prevent double device hard-reset due to 2 adjacent H/W events.
- Set device status 'malfunction' while in rmmod.
- Firmware related fixes:
- Extend preboot timeout because preboot loading might take longer than
expected in certain cases.
- Add a protection mechanism for the Event Queue. In case it is full, the
firmware will be able to notify about it through a dedicated interrupt.
- Perform device hard-reset in case scrubbing of memory has failed.
- Bug fixes and code cleanups:
- Small fixes of dma-buf handling in Gaudi2, such as handling an offset != 0,
using the correct exported size, creation of sg table.
- Fix spmu mask creation.
- Fix bug in wait for cs completion for decoder workloads.
- Cleanup Greco name from documentation.
- Fix bug in recording timestamp during cs completion interrupt handling.
- Fix CoreSight ETF configuration and flush logic.
- Fix small bug in hpriv_list handling (the list that contains the private

Merge tag 'drm-habanalabs-next-2023-10-10' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next
This tag contains habanalabs driver changes for v6.7.
The notable changes are:
- uAPI changes:
- Expose tsc clock sampling to better sync clock information in profiler.
- Enhance engine error reporting in the info ioctl.
- Block access to the eventfd operations through the control device.
- Disable the option of the user to register multiple times with the same
offset for timestamp dump by the driver. If a user wants to use the same
offset in the timestamp buffer for different interrupt, it needs to first
de-register the offset.
- When exporting dma-buf (for p2p), force the user to specify size/offset
in multiples of PAGE_SIZE. This is instead of the driver doing the
rounding to PAGE_SIZE, which has caused the driver to map more memory
than was intended by the user.
- New features and improvements:
- Complete the move of the driver to the accel subsystem by removing the
custom habanalabs class and major and registering to accel subsystem.
- Move the firmware interface files to include/linux/habanalabs. This is
a pre-requisite for upstreaming the NIC drivers of Gaudi (as they need to
include those files).
- Perform device hard-reset upon PCIe AXI drain event to prevent the failure
from cascading to different IP blocks in the SoC. In secured environments,
this is done automatically by the firmware.
- Print device name when it is removed for better debuggability.
- Add support for trace of dma map sgtable operations.
- Optimize handling of user interrupts by splitting the interrupts to two
lists. One list for fast handling and second list for handling with
timestamp recording, which is slower.
- Prevent double device hard-reset due to 2 adjacent H/W events.
- Set device status 'malfunction' while in rmmod.
- Firmware related fixes:
- Extend preboot timeout because preboot loading might take longer than
expected in certain cases.
- Add a protection mechanism for the Event Queue. In case it is full, the
firmware will be able to notify about it through a dedicated interrupt.
- Perform device hard-reset in case scrubbing of memory has failed.
- Bug fixes and code cleanups:
- Small fixes of dma-buf handling in Gaudi2, such as handling an offset != 0,
using the correct exported size, creation of sg table.
- Fix spmu mask creation.
- Fix bug in wait for cs completion for decoder workloads.
- Cleanup Greco name from documentation.
- Fix bug in recording timestamp during cs completion interrupt handling.
- Fix CoreSight ETF configuration and flush logic.
- Fix small bug in hpriv_list handling (the list that contains the private
data per process that opens our device).
