mptcp: introduce MPTCP_FULL_INFO getsockopt
Some user-space applications want to monitor the subflows utilization. Dumping the per subflow tcp_info is not enough, as the PM could close and re-create the subflows under-the-hood, fooling the accounting. Even checking the src/dst addresses used by each subflow could not be enough, because new subflows could re-use the same address/port of the just closed one. This patch introduces a new socket option, allow dumping all the relevant information all-at-once (everything, everywhere...), in a consistent manner.

mptcp: track some aggregate data counters
Currently there are no data transfer counters accounting for all the subflows used by a given MPTCP socket. The user-space can compute such figures aggregating the subflow info, but that is inaccurate if any subflow is closed before the MPTCP socket itself. Add the new counters in the MPTCP socket itself and expose them via the existing diag and sockopt. While touching mptcp_diag_fill_info(), acquire the relevant locks before fetching the msk data, to ensure better data consistency Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/385 Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: Matthieu Baerts <matthieu.baerts@tessares.net> Signed-off-by: Matthieu Baerts <matthieu.baerts@tessares.net> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: openvswitch: add support for l4 symmetric hashing
Since its introduction, the ovs module execute_hash action allowed
hash algorithms other than the skb->l4_hash to be used. However,
additional hash algorithms were not implemented. This means flows
requiring different hash distributions weren't able to use the
kernel datapath.
Now, introduce support for symmetric hashing algorithm as an
alternative hash supported by the ovs module using the flow
dissector.
Output of flow using l4_sym hash:
recirc_id(0),in_port(3),eth(),eth_type(0x0800),
ipv4(dst=64.0.0.0/192.0.0.0,proto=6,frag=no), packets:30473425,

actions:hash(sym_l4(0)),recirc(0xd)

net: ethtool: correct MAX attribute value for stats
When compiling YNL generated code compiler complains about
array-initializer-out-of-bounds. Turns out the MAX value
for STATS_GRP uses the value for STATS.
This may lead to random corruptions in user space (kernel
itself doesn't use this value as it never parses stats).

bpf: netfilter: Add BPF_NETFILTER bpf_attach_type
Andrii Nakryiko writes:
And we currently don't have an attach type for NETLINK BPF link.
Thankfully it's not too late to add it. I see that link_create() in
kernel/bpf/syscall.c just bypasses attach_type check. We shouldn't
have done that. Instead we need to add BPF_NETLINK attach type to enum
bpf_attach_type. And wire all that properly throughout the kernel and
libbpf itself.
This adds BPF_NETFILTER and uses it. This breaks uabi but this
wasn't in any non-rc release yet, so it should be fine.
v2: check link_attack prog type in link_create too

net/sched: taprio: add netlink reporting for offload statistics counters
Offloading drivers may report some additional statistics counters, some of them even suggested by 802.1Q, like TransmissionOverrun. In my opinion we don't have to limit ourselves to reporting counters only globally to the Qdisc/interface, especially if the device has more detailed reporting (per traffic class), since the more detailed info is valuable for debugging and can help identifying who is exceeding its time slot. But on the other hand, some devices may not be able to report both per TC and global stats. So we end up reporting both ways, and use the good old ethtool_put_stat() strategy to determine which statistics are supported by this NIC. Statistics which aren't set are simply not reported to netlink. For this reason, we need something dynamic (a nlattr nest) to be reported through TCA_STATS_APP, and not something daft like the fixed-size and inextensible struct tc_codel_xstats. A good model for xstats which are a nlattr nest rather than a fixed struct seems to be cake. # Global stats $ tc -s qdisc show dev eth0 root # Per-tc stats $ tc -s class show dev eth0 Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Acked-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Signed-off-by: David S.

net/sched: flower: Allow matching on layer 2 miss
Add the 'TCA_FLOWER_L2_MISS' netlink attribute that allows user space to
match on packets that encountered a layer 2 miss. The miss indication is
set as metadata in the tc skb extension by the bridge driver upon FDB or
MDB lookup miss and dissected by the flow dissector to the
'FLOW_DISSECTOR_KEY_META' key.
The use of this skb extension is guarded by the 'tc_skb_ext_tc' static
key. As such, enable / disable this key when filters that match on layer
2 miss are added / deleted.
Tested:
# cat tc_skb_ext_tc.py
#!/usr/bin/env -S drgn -s vmlinux
refcount = prog["tc_skb_ext_tc"].key.enabled.counter.value_()
print(f"tc_skb_ext_tc reference count is {refcount}")

bpf: Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
Current UAPI of BPF_OBJ_PIN and BPF_OBJ_GET commands of bpf() syscall forces users to specify pinning location as a string-based absolute or relative (to current working directory) path. This has various implications related to security (e.g., symlink-based attacks), forces BPF FS to be exposed in the file system, which can cause races with other applications. One of the feedbacks we got from folks working with containers heavily was that inability to use purely FD-based location specification was an unfortunate limitation and hindrance for BPF_OBJ_PIN and BPF_OBJ_GET commands. This patch closes this oversight, adding path_fd field to BPF_OBJ_PIN and BPF_OBJ_GET UAPI, following conventions established by *at() syscalls for dirfd + pathname combinations. This now allows interesting possibilities like working with detached BPF FS mount (e.g., to perform multiple pinnings without running a risk of someone interfering with them), and generally making pinning/getting more secure and not prone to any races and/or security attacks. This is demonstrated by a selftest added in subsequent patch that takes advantage of new mount APIs (fsopen, fsconfig, fsmount) to demonstrate creating detached BPF FS mount, pinning, and then getting BPF map out of it, all while never exposing this private instance of BPF FS to outside worlds.

ipv{4,6}/raw: fix output xfrm lookup wrt protocol
With a raw socket bound to IPPROTO_RAW (ie with hdrincl enabled), the
protocol field of the flow structure, build by raw_sendmsg() /
rawv6_sendmsg()), is set to IPPROTO_RAW. This breaks the ipsec policy
lookup when some policies are defined with a protocol in the selector.
For ipv6, the sin6_port field from 'struct sockaddr_in6' could be used to
specify the protocol. Just accept all values for IPPROTO_RAW socket.
For ipv4, the sin_port field of 'struct sockaddr_in' could not be used
without breaking backward compatibility (the value of this field was never
checked). Let's add a new kind of control message, so that the userland
could specify which protocol is used.

net: vxlan: Add nolocalbypass option to vxlan.
If a packet needs to be encapsulated towards a local destination IP, the packet will undergo a "local bypass" and be injected into the Rx path as if it was received by the target VXLAN device without undergoing encapsulation. If such a device does not exist, the packet will be dropped. There are scenarios where we do not want to perform such a bypass, but instead want the packet to be encapsulated and locally received by a user space program for post-processing. To that end, add a new VXLAN device attribute that controls whether a "local bypass" is performed or not. Default to performing a bypass to maintain existing behavior.

s390:
* More phys_to_virt conversions
* Improvement of AP management for VSIE (nested virtualization)
ARM64:
* Numerous fixes for the pathological lock inversion issue that
plagued KVM/arm64 since... forever.
* New framework allowing SMCCC-compliant hypercalls to be forwarded
to userspace, hopefully paving the way for some more features
being moved to VMMs rather than be implemented in the kernel.
* Large rework of the timer code to allow a VM-wide offset to be
applied to both virtual and physical counters as well as a
per-timer, per-vcpu offset that complements the global one.
This last part allows the NV timer code to be implemented on
top.
* A small set of fixes to make sure that we don't change anything
affecting the EL1&0 translation regime just after having having
taken an exception to EL2 until we have executed a DSB. This
ensures that speculative walks started in EL1&0 have completed.
* The usual selftest fixes and improvements.
KVM x86 changes for 6.4:
* Optimize CR0.WP toggling by avoiding an MMU reload when TDP is enabled,
and by giving the guest control of CR0.WP when EPT is enabled on VMX
(VMX-only because SVM doesn't support per-bit controls)
* Add CR0/CR4 helpers to query single bits, and clean up related code
where KVM was interpreting kvm_read_cr4_bits()'s "unsigned long" return
as a bool
* Move AMD_PSFD to cpufeatures.h and purge KVM's definition
* Avoid unnecessary writes+flushes when the guest is only adding new PTEs
* Overhaul .sync_page() and .invlpg() to utilize .sync_page()'s optimizations
when emulating invalidations
* Clean up the range-based flushing APIs
* Revamp the TDP MMU's reaping of Accessed/Dirty bits to clear a single
A/D bit using a LOCK AND instead of XCHG, and skip all of the "handle
changed SPTE" overhead associated with writing the entire entry
* Track the number of "tail" entries in a pte_list_desc to avoid having
to walk (potentially) all descriptors during insertion and deletion,
which gets quite expensive if the guest is spamming fork()
* Disallow virtualizing legacy LBRs if architectural LBRs are available,
the two are mutually exclusive in hardware
* Disallow writes to immutable feature MSRs (notably PERF_CAPABILITIES)
after KVM_RUN, similar to CPUID features
* Overhaul the vmx_pmu_caps selftest to better validate PERF_CAPABILITIES
* Apply PMU filters to emulated events and add test coverage to the
pmu_event_filter selftest
x86 AMD:
* Add support for virtual NMIs
* Fixes for edge cases related to virtual interrupts
x86 Intel:
* Don't advertise XTILE_CFG in KVM_GET_SUPPORTED_CPUID if XTILE_DATA is
not being reported due to userspace not opting in via prctl()
* Fix a bug in emulation of ENCLS in compatibility mode
* Allow emulation of NOP and PAUSE for L2
* AMX selftests improvements
* Misc cleanups
MIPS:
* Constify MIPS's internal callbacks (a leftover from the hardware enabling
rework that landed in 6.3)
Generic:
* Drop unnecessary casts from "void *" throughout kvm_main.c
* Tweak the layout of "struct kvm_mmu_memory_cache" to shrink the struct
size by 8 bytes on 64-bit kernels by utilizing a padding hole

* Fix goof introduced by the conversion to rST

NFSD 6.4 Release Notes
The big ticket item for this release is support for RPC-with-TLS [RFC 9289] has been added to the Linux NFS server. The goal is to provide a simple-to-deploy, low-overhead in-transit confidentiality and peer authentication mechanism. It can supplement NFS Kerberos and it can protect the use of legacy non-cryptographic user authentication flavors such as AUTH_SYS. The TLS Record protocol is handled entirely by kTLS, meaning it can use either software encryption or offload encryption to smart NICs. Work continues on improving NFSD's open file cache. Among the many clean-ups in that area is a patch to convert the rhashtable to use the list-hashing version of that data structure. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmRK/JMACgkQM2qzM29m f5cF5A/+JZFRSPlfSYt0YHzUQQSDdYn5n/IG9TwJQd62xheu083WuKRaCOYYoOhg 06nZd6p7nuF1E0n2ZWOKSE6YkBSE6z4M6KrQlm6lCe/nmxYCR87IYfJCXuL+Yf0e /LdL4OTvDHzY5ec1DreERldPIUJ8GFzwChH8/z4XwbNDR7qJkF/gf8YxpFr+8K+j Cfyl8woZiEze/Nvxy1YtAqa7HMEpitt0aWJN55rHwTh9c3b0nmDzziYFcVqXgybJ /qUHfHBak66ll8RqhcQ3BMuyfszwASERbPsaZ2a5F/RaxLL5ZWfFyhgQwm+PZWT+ J5DdSBwLEQYtKQGD41A1aorP6v/u2QelfWrl4S7/qjRpREp8Ba2IU4fYLjGb1499 Imk68BA7NwFp87tdMi/7en1VVgina4U/S3X71aUYWe+C0g48BfTrVwq4SVbQSAo4 1638vbZnrJbsJMr9OaaysKWfv4KZB020Ji1KVwuqmgy5F8kdfJCCQ2UR/fHuJ3DY R0Zrd1Ryjwr83viP+Xj0ERiW405gPdCT0RJqoA7rznRPCqT5M42tf5z65uO7iZeE C1udgDaoQOtioKlem6FcDXLkryf986slGA7V91lat/Jt8A5jLKQfjVe3Q+kaaqXP ka1DQnYelzMzILQQs39cqW5pShrH8e3tfRZ7JhdBgrpxVXz9ZZM= =lA2+ -----END PGP SIGNATURE----- Merge tag 'nfsd-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "The big ticket item for this release is that support for RPC-with-TLS [RFC 9289] has been added to the Linux NFS server.

tracing updates for 6.4:
- User events are finally ready!
After lots of collaboration between various parties, we finally locked
down on a stable interface for user events that can also work with user
space only tracing. This is implemented by telling the kernel (or user
space library, but that part is user space only and not part of this
patch set), where the variable is that the application uses to know if
something is listening to the trace. There's also an interface to tell
the kernel about these events, which will show up in the
/sys/kernel/tracing/events/user_events/ directory, where it can be
enabled. When it's enabled, the kernel will update the variable, to tell
the application to start writing to the kernel.
See https://lwn.net/Articles/927595/
- Cleaned up the direct trampolines code to simplify arm64 addition of
direct trampolines. Direct trampolines use the ftrace interface but
instead of jumping to the ftrace trampoline, applications (mostly BPF)
can register their own trampoline for performance reasons.
- Some updates to the fprobe infrastructure. fprobes are more efficient than
kprobes, as it does not need to save all the registers that kprobes on
ftrace do. More work needs to be done before the fprobes will be exposed
as dynamic events.
- More updates to references to the obsolete path of
/sys/kernel/debug/tracing for the new /sys/kernel/tracing path.
- Add a seq_buf_do_printk() helper to seq_bufs, to print a large buffer line
by line instead of all at once. There's users in production kernels that
have a large data dump that originally used printk() directly, but the
data dump was larger than what printk() allowed as a single print.
Using seq_buf() to do the printing fixes that.
- Add /sys/kernel/tracing/touched_functions that shows all functions that
was every traced by ftrace or a direct trampoline. This is used for
debugging issues where a traced function could have caused a crash by
a bpf program or live patching.
- Add a "fields" option that is similar to "raw" but outputs the fields of
the events. It's easier to read by humans.
- Some minor fixes and clean ups.

uapi nbd: add cookie alias to handle
The uapi <linux/nbd.h> header declares a 'char handle[8]' per request; which is overloaded in English (are you referring to "handle" the verb, such as handling a signal or writing a callback handler, or "handle" the noun, the value used in a lookup table to correlate a response back to the request). Many user-space NBD implementations (both servers and clients) have instead used 'uint64_t cookie' or similar, as it is easier to directly assign an integer than to futz around with memcpy. In fact, upstream documentation is now encouraging this shift in terminology: https://github.com/NetworkBlockDevice/nbd/commit/ca4392eb2b Accomplish this by use of an anonymous union to provide the alias for anyone getting the definition from the uapi; this does not break existing clients, while exposing the nicer name for those who prefer it. Note that block/nbd.c still uses the term handle (in fact, it actually combines a 32-bit cookie and a 32-bit tag into the 64-bit handle), but that internal usage is not changed by the public uapi, since no compliant NBD server has any reason to inspect or alter the 64 bits sent over the socket.

uapi nbd: improve doc links to userspace spec
The uapi <linux/nbd.h> header intentionally documents only the NBD server features that the kernel module will utilize as a client. But while it already had one mention of skipped bits due to userspace extensions, it did not actually direct the reader to the canonical source to learn about those extensions. While touching comments, fix an outdated reference that listed only READ and WRITE as commands.

Networking changes for 6.4.
Core
----
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances.
- Reduce compound page head access for zero-copy data transfers.
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
- Threaded NAPI improvements, adding defer skb free support and unneeded
softirq avoidance.
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking.
- Add lockless accesses annotation to sk_err[_soft].
- Optimize again the skb struct layout.
- Extends the skb drop reasons to make it usable by multiple
subsystems.
- Better const qualifier awareness for socket casts.
BPF
---
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and variable-sized
accesses.
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward.
- Add more precise memory usage reporting for all BPF map types.
- Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params.
- Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton.
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF
open-coded iterators allowing for less restrictive looping capabilities.
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
programs to NULL-check before passing such pointers into kfunc.
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
local storage maps.
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps.
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree.
- Add BPF verifier support for ST instructions in convert_ctx_access()
which will help new -mcpu=v4 clang flag to start emitting them.
- Add ARM32 USDT support to libbpf.
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations.
Protocols
---------
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address.
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
- Add the handshake upcall mechanism, allowing the user-space
to implement generic TLS handshake on kernel's behalf.
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures.
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers.
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction.
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore.
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter
---------
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged.
- Update bridge netfilter and ovs conntrack helpers to handle
IPv6 Jumbo packets properly, i.e. fetch the packet length
from hop-by-hop extension header. This is needed for BIT TCP
support.
- The iptables 32bit compat interface isn't compiled in by default
anymore.
- Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.
Driver API
----------
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time.
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them.
- Allow the page_pool to directly recycle the pages from safely
localized NAPI.
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization.
- Add YNL support for user headers and struct attrs.
- Add partial YNL specification for devlink.
- Add partial YNL specification for ethtool.
- Add tc-mqprio and tc-taprio support for preemptible traffic classes.
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device.
- Add basic LED support for switch/phy.
- Add NAPI documentation, stop relaying on external links.
- Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
work to make the hardware timestamping layer selectable by user
space.
- Add transceiver support and improve the error messages for CAN-FD
controllers.

KVM/arm64 updates for 6.4
- Numerous fixes for the pathological lock inversion issue that plagued KVM/arm64 since... forever. - New framework allowing SMCCC-compliant hypercalls to be forwarded to userspace, hopefully paving the way for some more features being moved to VMMs rather than be implemented in the kernel. - Large rework of the timer code to allow a VM-wide offset to be applied to both virtual and physical counters as well as a per-timer, per-vcpu offset that complements the global one. This last part allows the NV timer code to be implemented on top. - A small set of fixes to make sure that we don't change anything affecting the EL1&0 translation regime just after having having taken an exception to EL2 until we have executed a DSB.

dlm for 6.4
Remove some unused features (related to lock timeouts) that have been previously scheduled for removal. Fix a bug where the pending callback flag would be incorrectly cleared, which could potentially result in missing a completion callback. Use an unbound workqueue for dlm socket handling so that socket operations can be processed with less delay. Fix possible lockspace join connection errors with large clusters (e.g. over 16 nodes) caused by a small socket backlog setting. Use atomic bit ops for internal flags to help avoid mistakes copying flag values from messages. Fix recently introduced bug where memory for lvb data could be unnecessarily allocated for a lock. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJkR/JxAAoJEDgbc8f8gGmq2p0P/j3OcxdOXkx9LVpKdjuAhK/M A4Q46J9Z/Ytl4vT7x6i4x2fZXk8cTOkQZ3TkYMGbIc8LV4FZpO4/pIP+GnSDkmwY 1/AJgauskoewPuCNe+SUCawFMKPhUCXKOXNhyfAHlBS+NS8iIJhVKOP7mOMUawKs 4WiI6fEFBig2z56LHgnAIdzx1UGJ+AE1XlwEca1jVvtMYW03HX9h5Tt1BP1NeAKx oPrYQaUsctHlAI+fo0PnjimGcjXa2av9YNnTHpqVfYw6ntSdriEXQVosX/tcRV8E dVXmQP2Ox20mNRu9vHkAK8x2LQLj7HuwmohdUvvDFp1cIEglbiRdF6IolyhD2Up1 ETeJ5EU/6ktJOHrOewUCTcJoLrAcwmklgj9fzvW7fPN4zNsEUCYgoenuSK8bW+la jDbO26Rh+cMg2pC6Rz8z8azadwTQlFXDjvTDOnmb2jr+tfIEWj/VTWCTQ4Un3EEg 4xJ1dCvlLCRkYoDN3QTF9TxapSTohtjtQl85yrLULhdUWhQuRQd93rHeNgwDf8Ys NUzuL+IR+SEfvVyRezYfdyUBT26ld8pGVzJqlKvXUXTPBypnw9aoGAYhXx3A8fYo QLIz7lc0/pvkWaQ9zNyedf8LDIYCbZuTcMpmTEgLy+q6BTJWS2ZJT5oeNvGvnRw5 Zc7iUmGNQ5XKuVEhtTFA =900J -----END PGP SIGNATURE----- Merge tag 'dlm-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm Pull dlm updates from David Teigland: - Remove some unused features (related to lock timeouts) that have been previously scheduled for removal - Fix a bug where the pending callback flag would be incorrectly cleared, which could potentially result in missing a completion callback - Use an unbound workqueue for dlm socket handling so that socket operations can be processed with less delay - Fix possible lockspace join connection errors with large clusters (e.g. over 16 nodes) caused by a small socket backlog setting - Use atomic bit ops for internal flags to help avoid mistakes copying flag values from messages - Fix recently introduced bug where memory for lvb data could be unnecessarily allocated for a lock * tag 'dlm-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm: fs: dlm: stop unnecessarily filling zero ms_extra bytes fs: dlm: switch lkb_sbflags to atomic ops fs: dlm: rsb hash table flag value to atomic ops fs: dlm: move internal flags to atomic ops fs: dlm: change dflags to use atomic bits fs: dlm: store lkb distributed flags into own value fs: dlm: remove DLM_IFL_LOCAL_MS flag fs: dlm: rename stub to local message flag fs: dlm: remove deprecated code parts DLM: increase socket backlog to avoid hangs with 16 nodes fs: dlm: add unbound flag to dlm_io workqueue fs: dlm: fix DLM_IFL_CB_PENDING gets overwritten |

Pull btrfs updates from David Sterba:
"Mostly core changes and cleanups, some notable fixes and two
performance improvements in directory logging.
The IO path cleanups are removing or refactoring old code, scrub main
loop has been completely rewritten also refactoring old code.
There are some changes to non-btrfs code, mostly trivial, the cgroup
punt bio logic is only moved from generic code.
Performance improvements:
- improve logging changes in a directory during one transaction,
avoid iterating over items and reduce lock contention (fsync time
4x lower)
- when logging directory entries during one transaction, reduce
locking of subvolume trees by checking tree-log instead
(improvement in throughput and latency for concurrent access to a
subvolume)
Notable fixes:
- dev-replace:
- properly honor read mode when requested to avoid reading from
source device
- target device won't be used for eventual read repair, this is
unreliable for NODATASUM files
- when there are unpaired (and unrepairable) metadata during
replace, exit early with error and don't try to finish whole
operation
- scrub ioctl properly rejects unknown flags
- fix global block reserve calculations
- fix partial direct io write when there's a page fault in the
middle, iomap will try to continue with partial request but the
btrfs part did not match that, this can lead to zeros written
instead of data
Core changes:
- io path:
- continued cleanups and refactoring around bio handling
- extent io submit path simplifications and cleanups
- flush write path simplifications and cleanups
- rework logic of passing sync mode of bio, with further cleanups
- rewrite scrub code flow, restructure how the stripes are enumerated
and verified in a more unified way
- allow to set lower threshold for block group reclaim in debug mode
to aid zoned mode testing
- remove obsolete time-based delayed ref throttling logic when
truncating items
- DREW locks are not using percpu variables anymore
- more warning fixes (-Wmaybe-uninitialized)
- u64 division simplifications
- error handling improvements
Non-btrfs code changes:
- push cgroup punt bio logic to btrfs code (there was no other user
of that), the functionality can be now selected separately by
BLK_CGROUP_PUNT_BIO
