SUNRPC: Revert e0a912e8dd
Flamegraph analysis showed that the cork/uncork calls consume nearly a third of the CPU time spent in svc_tcp_sendto(). The other two consumers are mutex lock/unlock and svc_tcp_sendmsg(). Now that svc_tcp_sendto() coalesces RPC messages properly, there is no need to introduce artificial delays to prevent sending partial messages. After applying this change, I measured a 1.2K read IOPS increase for 8KB random I/O (several percent) on 56Gb IP over IB.

SUNRPC: Send RPC message on TCP with a single sock_sendmsg() call
There is now enough infrastructure in place to combine the stream record marker into the biovec array used to send each outgoing RPC message on TCP. The whole message can be more efficiently sent with a single call to sock_sendmsg() using a bio_vec iterator. Note that this also helps with RPC-with-TLS: the TLS implementation can now clearly see where the upper layer message boundaries are. Before, it would send each component of the xdr_buf (record marker, head, page payload, tail) in separate TLS records.

SUNRPC: Convert svc_tcp_sendmsg to use bio_vecs directly
Add a helper to convert a whole xdr_buf directly into an array of bio_vecs, then send this array instead of iterating piecemeal over the xdr_buf containing the outbound RPC message. Reviewed-by: David Howells <dhowells@redhat.com> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |

One clk driver fix and two clk framework fixes
- Fix an OOB access when devm_get_clk_from_child() is used and
devm_clk_release() casts the void pointer to the wrong type
- Move clk_rate_exclusive_{get,put}() within the correct ifdefs in
clk.h so that the stubs are used when CONFIG_COMMON_CLK=n
- Register the proper clk provider function depending on the value of
#clock-cells in the TI keystone driver

Pull RISC-V fixes from Palmer Dabbelt:
"This is obviously not ideal, particularly for something this late in
the cycle.
Unfortunately we found some uABI issues in the vector support while
reviewing the GDB port, which has triggered a revert -- probably a
good sign we should have reviewed GDB before merging this, I guess I
just dropped the ball because I was so worried about the context
extension and libc suff I forgot. Hence the late revert.
There's some risk here as we're still exposing the vector context for
signal handlers, but changing that would have meant reverting all of
the vector support. The issues we've found so far have been fixed
already and they weren't absolute showstoppers, so we're essentially
just playing it safe by holding ptrace support for another release (or
until we get through a proper userspace code review).
Summary:
- The vector ucontext extension has been extended with vlenb
- The vector registers ELF core dump note type has been changed to
avoid aliasing with the CSR type used in embedded systems
- Support for accessing vector registers via ptrace() has been

Tracing fixes for 6.5:
- Fix ring buffer being permanently disabled due to missed record_disabled() Changing the trace cpu mask will disable the ring buffers for the CPUs no longer in the mask. But it fails to update the snapshot buffer. If a snapshot takes place, the accounting for the ring buffer being disabled is corrupted and this can lead to the ring buffer being permanently disabled. - Add test case for snapshot and cpu mask working together - Fix memleak by the function graph tracer not getting closed properly. The iterator is used to read the ring buffer. When it opens, it calls the open function of a tracer, and when it is closed, it calls the close iteration. While a trace is being read, it is still possible to change the tracer. If this happens between the function graph tracer and the wakeup tracer (which uses function graph tracing), the tracers are not closed properly during when the iterator sees the switch, and the wakeup function did not initialize its private pointer to NULL, which is used to know if the function graph tracer was the last tracer. It could be fooled in thinking it is, but then on exit it does not call the close function of the function graph tracer to clean up its data. - Fix synthetic events on big endian machines, by introducing a union that does the conversions properly. - Fix synthetic events from printing out the number of elements in the stacktrace when it shouldn't. - Fix synthetic events stacktrace to not print a bogus value at the end. - Introduce a pipe_cpumask that prevents the trace_pipe files from being opened by more than one task (file descriptor). There was a race found where if splice is called, the iter->ent could become stale and events could be missed. There's no point reading a producer/consumer file by more than one task as they will corrupt each other anyway. Add a cpumask that keeps track of the per_cpu trace_pipe files as well as the global trace_pipe file that prevents more than one open of a trace_pipe file that represents the same ring buffer. This prevents the race from happening. - Fix ftrace samples for arm64 to work with older compilers. -----BEGIN PGP SIGNATURE----- iQJIBAABCgAyFiEEXtmkj8VMCiLR0IBM68Js21pW3nMFAmTn7hsUHHJvc3RlZHRA Z29vZG1pcy5vcmcACgkQ68Js21pW3nOSVg/9HVFTUX52yqvT9YLv8b1QZYMo2I5n to1nSbF9UUYIAMqkyNHuXU2TBj1I77JVkbsPEFsjYTN97CzJ/Zc8jNa6p7HgVure 1xUuaCgtOFPDjU6OpTa6wFRt4usU1UM8Noc/ii0WDUGsA+RKBAKmGUsNmuDHx1Ae a3uJTLR4VHMeAkbtth/8f6RHBVocDVSYPQbKnC0PksGW1wg9e9PU2G6+o3069I1Q qbOZJqvGDpeaapjyG2LYrDwkVGOPSvUJuJNfcjcNcyKoHSqxZzBb+feY16NhWDm9 idpyHLE4qF1nvlh1SIpErFl8Bu5MG9CN8a+xrx3ufd6i1jO4bcHyRD9XmjG4p72+ zVshoS86DI4KCK9wHxJ/5/SU6XuL6JoNTP7NhmDIX83QCuZwgTOa8C2xzHKHu58F In13IhJqS5ob6Jy25a/bAy0CbdTl0cjQvMfXrrYK0ZWuEBWgBUDqwB/eKY6oq79D oTKmFNOZsuiLAhPywAoY5cAqQtftpy5Ul8o6ed3RAw3th0WC4EeXIk5eUu5g/ABI 1ZfnpeY5al/JROFGXWxyn964RRjoVpbC1M6NVTz33e7No+r2KSRlLb5ZEWZVVIcZ My96QiZXamBZ/EOR7x72yFWxXBSuACu9nvbSSZRnbEGujoKwDb89xtgWzSNuR/wi GexDcj6qWfODrfc= =CI9f -----END PGP SIGNATURE----- Merge tag 'trace-v6.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix ring buffer being permanently disabled due to missed record_disabled() Changing the trace cpu mask will disable the ring buffers for the CPUs no longer in the mask.

drm: Add an HPD poll helper to reschedule the poll work
Add a helper to reschedule drm_mode_config::output_poll_work after
polling has been enabled for a connector (and needing a reschedule,
since previously polling was disabled for all connectors and hence
output_poll_work was not running).
This is needed by the next patch fixing HPD polling on i915.

netfilter: nf_tables: defer gc run if previous batch is still pending
Don't queue more gc work, else we may queue the same elements multiple
times.
If an element is flagged as dead, this can mean that either the previous
gc request was invalidated/discarded by a transaction or that the previous
request is still pending in the system work queue.
The latter will happen if the gc interval is set to a very low value,
e.g. 1ms, and system work queue is backlogged.
The sets refcount is 1 if no previous gc requeusts are queued, so add
a helper for this and skip gc run if old requests are pending.
Add a helper for this and skip the gc run in this case.

netfilter: nf_tables: validate all pending tables
We have to validate all tables in the transaction that are in
VALIDATE_DO state, the blamed commit below did not move the break
statement to its right location so we only validate one table.
Moreover, we can't init table->validate to _SKIP when a table object
is allocated.
If we do, then if a transcaction creates a new table and then
fails the transaction, nfnetlink will loop and nft will hang until
user cancels the command.
Add back the pernet state as a place to stash the last state encountered.
This is either _DO (we hit an error during commit validation) or _SKIP
(transaction passed all checks).

RISC-V: Remove ptrace support for vectors
We've found two bugs here: NT_RISCV_VECTOR steps on NT_RISCV_CSR (which
is only for embedded), and we don't have vlenb in the core dumps. Given
that we've have a pair of bugs croup up as part of the GDB review we've
probably got other issues, so let's just cut this for 6.5 and get it
right.

mm: enable page walking API to lock vmas during the walk
walk_page_range() and friends often operate under write-locked mmap_lock. With introduction of vma locks, the vmas have to be locked as well during such walks to prevent concurrent page faults in these areas. Add an additional member to mm_walk_ops to indicate locking requirements for the walk. The change ensures that page walks which prevent concurrent page faults by write-locking mmap_lock, operate correctly after introduction of per-vma locks. With per-vma locks page faults can be handled under vma lock without taking mmap_lock at all, so write locking mmap_lock would not stop them. The change ensures vmas are properly locked during such walks. A sample issue this solves is do_mbind() performing queue_pages_range() to queue pages for migration. Without this change a concurrent page can be faulted into the area and be left out of migration.

smaps: use vm_normal_page_pmd() instead of follow_trans_huge_pmd()
We shouldn't be using a GUP-internal helper if it can be avoided. Similar to smaps_pte_entry() that uses vm_normal_page(), let's use vm_normal_page_pmd() that similarly refuses to return the huge zeropage. In contrast to follow_trans_huge_pmd(), vm_normal_page_pmd(): (1) Will always return the head page, not a tail page of a THP. If we'd ever call smaps_account with a tail page while setting "compound = true", we could be in trouble, because smaps_account() would look at the memmap of unrelated pages. If we're unlucky, that memmap does not exist at all. Before we removed PG_doublemap, we could have triggered something similar as in commit |

ipv4: fix data-races around inet->inet_id
UDP sendmsg() is lockless, so ip_select_ident_segs()
can very well be run from multiple cpus [1]
Convert inet->inet_id to an atomic_t, but implement
a dedicated path for TCP, avoiding cost of a locked
instruction (atomic_add_return())
Note that this patch will cause a trivial merge conflict
because we added inet->flags in net-next tree.
v2: added missing change in

sock: Fix misuse of sk_under_memory_pressure()
The status of global socket memory pressure is updated when:
a) __sk_mem_raise_allocated():
enter: sk_memory_allocated(sk) > sysctl_mem[1]
leave: sk_memory_allocated(sk) <= sysctl_mem[0]
b) __sk_mem_reduce_allocated():
leave: sk_under_memory_pressure(sk) &&
sk_memory_allocated(sk) < sysctl_mem[0]
So the conditions of leaving global pressure are inconstant, which
may lead to the situation that one pressured net-memcg prevents the
global pressure from being cleared when there is indeed no global
pressure, thus the global constrains are still in effect unexpectedly
on the other sockets.
This patch fixes this by ignoring the net-memcg's pressure when
deciding whether should leave global memory pressure.

tracing/synthetic: Use union instead of casts
The current code uses a lot of casts to access the fields member in struct
synth_trace_events with different sizes. This makes the code hard to
read, and had already introduced an endianness bug. Use a union and struct
instead.

First patch resolves a false-positive lockdep splat: rcu_dereference is used outside of rcu read lock. Let lockdep validate that the transaction mutex is locked. Second patch fixes a kdoc warning added in previous PR. Third patch fixes a memory leak: The catchall element isn't disabled correctly, this allows userspace to deactivate the element again. This results in refcount underflow which in turn prevents memory release. This was always broken since the feature was added in 5.13. Patch 4 fixes an incorrect change in the previous pull request: Adding a duplicate key to a set should work if the duplicate key has expired, restore this behaviour. All from myself. Patch #5 resolves an old historic artifact in sctp conntrack: a 300ms timeout for shutdown_ack. Increase this to 3s. From Xin Long. Patch #6 fixes a sysctl data race in ipvs, two threads can clobber the sysctl value, from Sishuai Gong. This is a day-0 bug that predates git history. Patches 7, 8 and 9, from Pablo Neira Ayuso, are also followups for the previous GC rework in nf_tables: The netlink notifier and the netns exit path must both increment the gc worker seqcount, else worker may encounter stale (free'd) pointers. ================ Signed-off-by: David S.

locking: remove spin_lock_prefetch
The only remaining consumer is new_inode, where it showed up in 2001 as
commit c37fa164f793 ("v2.4.9.9 -> v2.4.9.10") in a historical repo [1]
with a changelog which does not mention it.
Since then the line got only touched up to keep compiling.
While it may have been of benefit back in the day, it is guaranteed to
at best not get in the way in the multicore setting -- as the code
performs *a lot* of work between the prefetch and actual lock acquire,
any contention means the cacheline is already invalid by the time the
routine calls spin_lock(). It adds spurious traffic, for short.
On top of it prefetch is notoriously tricky to use for single-threaded
purposes, making it questionable from the get go.
As such, remove it.
I admit upfront I did not see value in benchmarking this change, but I
can do it if that is deemed appropriate.
Removal from new_inode and of the entire thing are in the same patch as
requested by Linus, so whatever weird looks can be directed at that guy.

Including fixes from netfilter, wireless and bpf.
Still trending up in size but the good news is that the "current"
regressions are resolved, AFAIK.
We're getting weirdly many fixes for Wake-on-LAN and suspend/resume
handling on embedded this week (most not merged yet), not sure why.
But those are all for older bugs.
Current release - regressions:
- tls: set MSG_SPLICE_PAGES consistently when handing encrypted
data over to TCP
Current release - new code bugs:
- eth: mlx5: correct IDs on VFs internal to the device (IPU)
Previous releases - regressions:
- phy: at803x: fix WoL support / reporting on AR8032
- bonding: fix incorrect deletion of ETH_P_8021AD protocol VID
from slaves, leading to BUG_ON()
- tun: prevent tun_build_skb() from exceeding the packet size limit
- wifi: rtw89: fix 8852AE disconnection caused by RX full flags
- eth/PCI: enetc: fix probing after

This series contains the following patches: 1) Do not skip expired elements during walk otherwise elements might never decrement the reference counter on data, leading to memleak. 2) Add a GC transaction API to replace the former attempt to deal with races between control plane and GC. GC worker sets on NFT_SET_ELEM_DEAD_BIT on elements and it creates a GC transaction to remove the expired elements, GC transaction could abort in case of interference with control plane and retried later (GC async). Set backends such as rbtree and pipapo also perform GC from control plane (GC sync), in such case, element deactivation and removal is safe because mutex is held then collected elements are released via call_rcu(). 3) Adapt existing set backends to use the GC transaction API. 4) Update rhash set backend to set on _DEAD bit to report deleted elements from datapath for GC. 5) Remove old GC batch API and the NFT_SET_ELEM_BUSY_BIT. * tag 'nf-23-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_tables: remove busy mark and gc batch API netfilter: nft_set_hash: mark set element as dead when deleting from packet path netfilter: nf_tables: adapt set backend to use GC transaction API netfilter: nf_tables: GC transaction API to avoid race with control plane netfilter: nf_tables: don't skip expired elements during walk ==================== Link: https://lore.kernel.org/r/20230810070830.24064-1-pablo@netfilter.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

x86/speculation: Add cpu_show_gds() prototype
The newly added function has two definitions but no prototypes:
drivers/base/cpu.c:605:16: error: no previous prototype for 'cpu_show_gds' [-Werror=missing-prototypes]
Add a declaration next to the other ones for this file to avoid the
warning.
