Linus Torvalds f8f5627a8a Merge tag 'net-7.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
 "With fixes from wireless, bluetooth and netfilter included we're back
  to each PR carrying 30%+ more fixes than in previous era.

  The good news is that so far none of the "extra" fixes are themselves
  causing real regressions. Not sure how much comfort that is.

  Current release - fix to a fix:

   - netdevsim: fix build if SKB_EXTENSIONS=n

   - eth: stmmac: skip VLAN restore when VLAN hash ops are missing

  Previous releases - regressions:

   - wifi: iwlwifi: mvm: don't send a 6E related command when
     not supported

  Previous releases - always broken:

   - some info leak fixes

   - add missing clearing of skb->cb[] on ICMP paths from tunnels

   - ipv6:
      - flowlabel: defer exclusive option free until RCU teardown
      - avoid overflows in ip6_datagram_send_ctl()

   - mpls: add seqcount to protect platform_labels from OOB access

   - bridge: improve safety of parsing ND options

   - bluetooth: fix leaks, overflows and races in hci_sync

   - netfilter: add more input validation, some to address bugs directly
     some to prevent exploits from cooking up broken configurations

   - wifi:
      - ath: avoid poor performance due to stopping the wrong
        aggregation session
      - virt_wifi: remove SET_NETDEV_DEV to avoid use-after-free

   - eth:
      - fec: fix the PTP periodic output sysfs interface
      - enetc: safely reinitialize TX BD ring when it has unsent frames"

Linux kernel
============

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
