Pull NFS client bugfixes from Trond Myklebust:
 "One more pull request. There was a bug in the fix to ensure that gss-
  proxy continues to work correctly after we fixed the AF_LOCAL socket
  leak in the RPC code. This therefore reverts that broken patch, and
  replaces it with one that works correctly.

  Stable fixes:

   - SUNRPC: Ensure that the gssproxy client can start in a connected
     state

  Bugfixes:

   - Revert "SUNRPC: Ensure gss-proxy connects on setup"

   - nfs: fix broken handling of the softreval mount option"

This reverts commit 892de36fd4a98fab3298d417c051d9099af5448d.

The gssproxy server is unresponsive when it calls into the kernel to
start the upcall service, so it will not reply to our RPC ping at all.

The find_next_netdev_feature() macro gets the "remaining length",
not bit index.
Passing "bit - 1" for the following iteration is wrong as it skips
the adjacent bit. Pass "bit" instead.

 "Two folio fixes for 5.18.

  Darrick and Brian have done amazing work debugging the race I created
  in the folio BIO iterator. The readahead problem was deterministic, so
  easy to fix.

   - Fix a race when we were calling folio_next() in the BIO folio iter
     without holding a reference, meaning the folio could be split or
     freed, and we'd jump to the next page instead of the intended next
     folio.

   - Fix readahead creating single-page folios instead of the intended
     large folios when doing reads that are not a power of two in size"

Pull networking fixes from Paolo Abeni:
 "Including fixes from can, rxrpc and wireguard.

  Previous releases - regressions:

   - igmp: respect RCU rules in ip_mc_source() and ip_mc_msfilter()

   - mld: respect RCU rules in ip6_mc_source() and ip6_mc_msfilter()

   - rds: acquire netns refcount on TCP sockets

   - rxrpc: enable IPv6 checksums on transport socket

   - nic: hinic: fix bug of wq out of bound access

   - nic: thunder: don't use pci_irq_vector() in atomic context

   - nic: bnxt_en: fix possible bnxt_open() failure caused by wrong RFS
     flag

   - nic: mlx5e:
      - lag, fix use-after-free in fib event handler
      - fix deadlock in sync reset flow

  Previous releases - always broken:

   - tcp: fix insufficient TCP source port randomness

   - can: grcan: grcan_close(): fix deadlock

   - nfc: reorder destructive operations in to avoid bugs

  Misc:

   - wireguard: improve selftests reliability"

* tag 'net-5.18-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (63 commits)
  NFC: netlink: fix sleep in atomic bug when firmware download timeout
  selftests: ocelot: tc_flower_chains: specify conform-exceed action for policer
  tcp: drop the hash_32() part from the index calculation
  tcp: increase source port perturb table to 2^16
  tcp: dynamically allocate the perturb table used by source ports
  tcp: add small random increments to the source port
  tcp: resalt the secret every 10 seconds

<title>block: Do not call folio_next() on an unreferenced folio</title>

It is unsafe to call folio_next() on a folio unless you hold a reference
on it that prevents it from being split or freed.  After returning
from the iterator, iomap calls folio_end_writeback() which may drop
the last reference to the page, or allow the page to be split.  If that
happens, the iterator will not advance far enough through the bio_vec,
leading to assertion failures like the BUG() in folio_end_writeback()
that checks we're not trying to end writeback on a page not currently
under writeback.  Other assertion failures were also seen, but they're
all explained by this one bug.

Fix the bug by remembering where the next folio starts before returning
from the iterator.  There are other ways of fixing this bug, but this
seems the simplest.
