Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextgrafted
Pull networking updates from Jakub Kicinski: "Core: - Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use. - Introduce sysctl to set default RPS configuration for new netdevs. - Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols: - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF: - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter: - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API: - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

+(Note: I consider version numbers as cheap. That means
+that I do not like numbers like 0.1 and the like for
+things that can be used since quite some time. But
+then, 3.1 doesn't mean 'perfectly stable', too.)
+
+Known bugs:
+-----------
+
+- Doesn't work on the alpha. The only 64/32-bit
+ problem that I'm aware of (pointer/int conversion
+ in readdir()) gives compiler warnings but is
+ apparently not causing the failure, as directory
+ reads basically work (but all files are of size 0).
+ Alas, I've got no alpha to debug. :-(
+
+- The partition checker (drivers/block/genhd.c)
+ doesn't work with devices which have 256 byte
+ blocks (some very old SCSI drives).
+
+- The feature to automatically make the fs clean
+ might leave a trashed file system with the
+ bitmap flag set valid.
+
+- When a file is truncated to a size that is not
+ a multiple of the blocksize, the rest of the
+ last allocated block is not cleared. Well,
+ this fs never claimed to be Posix conformant.
+
+Please direct bug reports to: zippel@linux-m68k.org

+------------
+
+- Changed partition checker to allow devices
+ with physical blocks != 512 bytes.
+
+- The partition checker now also ignores the
+ word at 0xd0 that Windows likes to write to.
+
+Version 3.9
+-----------
+
+- Moved cleanup from release_file() to put_inode().
+ This makes the first one obsolete.
+
+- truncate() zeroes the unused remainder of a
+ partially used last block when a file is truncated.
+ It also marks the inode dirty now (which is not
+ really necessary as notify_change() will do
+ it anyway).
+
+- Added a few comments, fixed some typos (and
+ introduced some new ones), made the debug messages
+ more consistent. Changed a bad example in the
+ doc file (affs.txt).
+
+- Sets the NOEXEC flag in read_super() for old file
+ systems, since you can't run programs on them.
+
+Version 3.8
+-----------
+Bill Hawes kindly reviewed the affs and sent me the
+patches he did. They're marked (BH). Thanks, Bill!
+
+- Cleanup of error handling in read_super().
+ Didn't release all resources in case of an
+ error. (BH)
+
+- put_inode() releases the ext cache only if it's
+ no longer needed. (BH)
+
+- One set of dentry callbacks is enough. (BH)
+
+- Cleanup of error handling in namei.c. (BH)
+
+- Cleanup of error handling in file.c. (BH)
+
+- The original blocksize of the device is
+ restored when the fs is unmounted. (BH)
+
+- getblock() did not invalidate the key cache
+ when it allocated a new block.
+
+- Removed some unnecessary locks as Bill
+ suggested.
+
+- Simplified match_name(), changed all hashing
+ and case insensitive name comparisons to use
+ uppercase. This makes the tolower() routines
+ obsolete.
+
+- Added mount option 'mufs' to force muFS
+ uid/gid interpretation.
+
+- File mode changes were not updated on disk.
+ This was fixed before, but somehow got lost.
+
+Version 3.7
+-----------
+
+- Added dentry callbacks to allow the dcache to
+ operate case insensitive and length ignorant
+ like the affs itself.
+
+- getblock() didn't update the lastblock field in the
+ inode if the fs was not an OFS. This bug only shows
+ up if a file was enlarged via truncate() and there
+ was not enough space.
+
+- Remove some more superfluous code left over from
+ the old link days ...
+
+- Fixed some oversights which were in patch 2.1.78.
+
+- Fixed a few typos.
+
+Version 3.6
+-----------
+
+- dentry changes. (Thanks to Jes Sorensen for his help.)
+
+- Fixed bug in balloc(): Superblock was not set dirty after
+ the bitmap was changed, so the bitmap wasn't sync'd.
+
+- Fixed nasty bug in find_new_zone(): If the current
+ zone number was zero, the loop didn't terminate,
+ causing a solid lock-up.
+
+- Removed support for old-style directory reads.
+
+- Fixed bug in add_entry(): When doing a sorted insert,
+ the pointer to the next entry in the hash chain wasn't
+ correctly byte-swapped. Since most of the users of the
+ affs use it on a 68k, they didn't notice. But why did
+ I not find this during my tests?
+
+- Fixed some oversights (version wasn't updated on some
+ directory changes).
+
+- Handling of hard links rewritten. To the VFS
+ they appear now as normal Unix links. They are
+ now resolved only once in lookup(). The backside
+ is that unlink(), rename() and rmdir() have to
+ be smart about them, but the result is worth the
+ effort. This also led to some code cleanup.
+
+- Changed name type to unsigned char; the test for
+ invalid filenames didn't work correctly.
+ (Thanks to Michael Krause for pointing at this.)
+
+- Changed mapping of executable flag.
+
+- Changed all network byte-order macros to the
+ recommended ones.
+
+- Added a remount function, so attempts to remount
+ a dircache filesystem or one with errors read/write
+ can be trapped. Previously, ro remounts didn't
+ flush the super block, and rw remounts didn't
+ create allocation zones ...
+
+- Call shrink_dcache_parent() in rmdir().
+ (Thanks to Bill Hawes.)
+
+- Permission checks in unlink().
+
+- Allow mounting of volumes with superfluous
+ bitmap pointers read only, also allows them
+ to be remounted read/write.
+
+- Owner/Group defaults now to the fs user (i.e.
+ the one that mounted it) instead of root. This
+ obsoletes the mount options uid and gid.
+
+- Argument to volume option could overflow the
+ name buffer. It is now silently truncated to
+ 30 characters. (Damn it! This kind of bug
+ is too embarrassing.)
+
+- Split inode.c into 2 files, the superblock
+ routines desperately wanted their own file.
+
+- truncate() didn't allocate an extension block
+ cache. If a file was extended by means of
+ truncate(), this led to an Oops.
+
+- fsuser is now checked last.
+
+- rename() will not ignore changes in filename
+ casing any more (though mv(1) still won't allow
+ you to do "mv oldname OldName").
+
+Version 3.5
+-----------
+
+- Extension block caches are now allocated on
+ demand instead of when a file is opened, as
+ files can be read and written without opening
+ them (e. g. the loopback device does this).
+
+- Removed an unused function.
+
+Version 3.4
+-----------
+
+- Hash chains are now sorted by block numbers.
+ (Thanks to Kars de Jong for finding this.)
+- Removed all unnecessary external symbols.
+
+Version 3.3
+-----------
+
+- Tried to make all types 'correct' and consistent.
+- Errors and warnings are now reported via a
+ function. They are all prefixed by a severity
+ and have the same appearance:
+ "AFFS: <function>: <error message>"
+ (There's one exception to this, as in that function
+ is no pointer to the super block available.)
+- The filesystem is remounted read-only after an
+ error.
+- The names of newly created filesystem objects are
+ now checked for validity.
+- Minor cleanups in comments.
+- Added this Changes file. At last!
+
+Version 3.2
+-----------
+
+- Extension block cache: Reading/writing of huge files
+ (several MB) is much faster (of course the added
+ overhead slows down opening, but this is hardly
+ noticeable).
+- The same get_block()-routine can now be used for
+ both OFS and FFS.
+- The super block is now searched in the block that
+ was calculated and in the one following. This
+ should remedy the round-off error introduced by
+ the 1-k blocks that Linux uses.
+- Minor changes to adhere to the new VFS interface.
+- The number of used blocks is now also calculated
+ if the filesystem is mounted read-only.
+- Prefixed some constants with AFFS_ to avoid name
+ clashes.
+- Removed 'EXPERIMENTAL' status.
+
+Version 3.1
+-----------
+
+- Fixed a nasty bug which didn't allow read-only
+ mounts.
+- Allow dir-cache filesystems to be mounted
+ read only.
+- OFS support.
+- Several other changes I just cannot remember
+ any more.
+
+Version 3.0
+-----------
+
+- Almost complete rewrite for the new VFS
+ interface in Linux 1.3.
+- Write support.
+- Support for hard and symbolic links.
+- Lots of things I remember even less ...
+
+Version 2.0
+-----------
+
+- Fixed a few things to get it compiled.
+- Automatic root block calculation.
+- Partition checker for genhd.c
+
+========================================
+
+Let's just call Ray Burr's original affs
+'Version 1.0'.
