02f0717e98 net/tcp: fix possible out-of-bounds reads in tcp_hash_fail()
syzbot managed to trigger a fault by sending TCP packets
with all flags being set.

v2:
 - While fixing this bug, add PSH flag handling and represent
   flags the way tcpdump does : [S], [S.], [P.]
 - Print 4-tuples more consistently between families.

When a Pause frame is received TX is delayed for some time. This is TX
flow control. In the same manner tx_pause is actually RX flow control.

cdbab62366 tcp: fix fastopen code vs usec TS
After blamed commit, TFO client-ack-dropped-then-recovery-ms-timestamps
packetdrill test failed.

David Morley and Neal Cardwell started investigating and Neal pointed
that we had :

tcp_conn_request()
  tcp_try_fastopen()
   -> tcp_fastopen_create_child
     -> child = inet_csk(sk)->icsk_af_ops->syn_recv_sock()
       -> tcp_create_openreq_child()
          -> copy req_usec_ts from req:
          newtp->tcp_usec_ts = treq->req_usec_ts;
          // now the new TFO server socket always does usec TS, no matter
          // what the route options are...
  send_synack()
    -> tcp_make_synack()
        // disable tcp_rsk(req)->req_usec_ts if route option is not present:
        if (tcp_rsk(req)->req_usec_ts < 0)
                tcp_rsk(req)->req_usec_ts = dst_tcp_usec_ts(dst);

tcp_conn_request() has the initial dst, we can initialize
tcp_rsk(req)->req_usec_ts there instead of later in send_synack();

This means tcp_rsk(req)->req_usec_ts can be a boolean.

Many thanks to David an Neal for their help.

63e201916b selftests: pmtu.sh: fix result checking
In the PMTU test, when all previous tests are skipped and the new test
passes, the exit code is set to 0. However, the current check mistakenly
treats this as an assignment, causing the check to pass every time.

Consequently, regardless of how many tests have failed, if the latest test
passes, the PMTU test will report a pass.

From XGMAC Core 3.20 and later, each Flexible PPS has individual PPSEN bit
to select Fixed mode or Flexible mode. The PPSEN must be set, or it stays
in Fixed PPS mode by default.

read-only reserved, and they are already in Flexible mode by default, our

e8ae8ad479 Fix termination state for idr_for_each_entry_ul()
The comment for idr_for_each_entry_ul() states

  after normal termination @entry is left with the value NULL

This is not correct in the case where UINT_MAX has an entry in the idr.
In that case @entry will be non-NULL after termination.
No current code depends on the documentation being correct, but to
save future code we should fix it.

Also fix idr_for_each_entry_continue_ul().  While this is not documented
as leaving @entry as NULL, the mellanox driver appears to depend on
it doing so.  So make that explicit in the documentation as well as in
the code.

security_inet_conn_request() reads reqsk's remote address, but it's not

23be1e0e2a dccp/tcp: Call security_inet_conn_request() after setting IPv6 addresses.
Initially, commit 4237c75c0a ("[MLSXFRM]: Auto-labeling of child
sockets") introduced security_inet_conn_request() in some functions
where reqsk is allocated.  The hook is added just after the allocation,
so reqsk's IPv6 remote address was not initialised then.

However, SELinux/Smack started to read it in netlbl_req_setattr()
after commit e1adea9270 ("calipso: Allow request sockets to be
relabelled by the lsm.").

Commit 284904aa79 ("lsm: Relocate the IPv4 security_inet_conn_request()
hooks") fixed that kind of issue only in TCPv4 because IPv6 labeling was
not supported at that time.  Finally, the same issue was introduced again
in IPv6.

Let's apply the same fix on DCCPv6 and TCPv6.

5a22fbcc10 net: dsa: lan9303: consequently nested-lock physical MDIO
When LAN9303 is MDIO-connected two callchains exist into
mdio->bus->write():

1. switch ports 1&2 ("physical" PHYs):

virtual (switch-internal) MDIO bus (lan9303_switch_ops->phy_{read|write})->
  lan9303_mdio_phy_{read|write} -> mdiobus_{read|write}_nested

2. LAN9303 virtual PHY:

virtual MDIO bus (lan9303_phy_{read|write}) ->
  lan9303_virt_phy_reg_{read|write} -> regmap -> lan9303_mdio_{read|write}

If the latter functions just take
mutex_lock(&sw_dev->device->bus->mdio_lock) it triggers a LOCKDEP
false-positive splat. It's false-positive because the first
mdio_lock in the second callchain above belongs to virtual MDIO bus, the
second mdio_lock belongs to physical MDIO bus.

Consequent annotation in lan9303_mdio_{read|write} as nested lock
(similar to lan9303_mdio_phy_{read|write}, it's the same physical MDIO bus)
prevents the following splat:

61e4a86600 rxrpc: Fix two connection reaping bugs
Fix two connection reaping bugs:

 (1) rxrpc_connection_expiry is in units of seconds, so
     rxrpc_disconnect_call() needs to multiply it by HZ when adding it to
     jiffies.

 (2) rxrpc_client_conn_reap_timeout() should set RXRPC_CLIENT_REAP_TIMER if
     local->kill_all_client_conns is clear, not if it is set (in which case
     we don't need the timer).  Without this, old client connections don't
     get cleaned up until the local endpoint is cleaned up.

Fixes: 5040011d07 ("rxrpc: Make the local endpoint hold a ref on a connected call")
Fixes: 0d6bf319bc ("rxrpc: Move the client conn cache management to the I/O thread")

74da779213 net/tcp_sigpool: Fix some off by one bugs
The "cpool_populated" variable is the number of elements in the cpool[]
array that have been populated.  It is incremented in
tcp_sigpool_alloc_ahash() every time we populate a new element.
Unpopulated elements are NULL but if we have populated every element then
this code will read one element beyond the end of the array.

TIPC bearer-related names including link names must be null-terminated
strings. If a link name which is not null-terminated is passed through
netlink, strstr() and similar functions can cause buffer overrun. This
causes the above issue.

This patch changes the nla_policy for bearer-related names from NLA_STRING
to NLA_NUL_STRING. This resolves the issue by ensuring that only
null-terminated strings are accepted as bearer-related names.

syzbot reported similar uninit-value issue related to bearer names [2]. The
root cause of this issue is that a non-null-terminated bearer name was
passed. This patch also resolved this issue.

Fixes: 0655f6a863 ("tipc: add bearer disable/enable to new netlink api")

The prp_fill_rct() function can fail.  In that situation, it frees the
skb and returns NULL.  Meanwhile on the success path, it returns the
original skb.  So it's straight forward to fix bug by using the returned

7b3ba18703 llc: verify mac len before reading mac header
LLC reads the mac header with eth_hdr without verifying that the skb
has an Ethernet header.

Syzbot was able to enter llc_rcv on a tun device. Tun can insert
packets without mac len and with user configurable skb->protocol
(passing a tun_pi header when not configuring IFF_NO_PI).

Add a mac_len test before all three eth_hdr(skb) calls under net/llc.

There are further uses in include/net/llc_pdu.h. All these are
protected by a test skb->protocol == ETH_P_802_2. Which does not
protect against this tun scenario.

But the mac_len test added in this patch in llc_fixup_skb will
indirectly protect those too. That is called from llc_rcv before any
other LLC code.

It is tempting to just add a blanket mac_len check in llc_rcv, but
not sure whether that could break valid LLC paths that do not assume
an Ethernet header. 802.2 LLC may be used on top of non-802.3
protocols in principle. The below referenced commit shows that used
to, on top of Token Ring.

At least one of the three eth_hdr uses goes back to before the start
of git history. But the one that syzbot exercises is introduced in
this commit. That commit is old enough (2008), that effectively all
stable kernels should receive this.

2b7ac0c87d tools: ynl-gen: don't touch the output file if content is the same
I often regenerate all YNL files in the tree to make sure they
are in sync with the codegen and specs. Generator rewrites
the files unconditionally, so since make looks at file modification
time to decide what to rebuild - my next build takes longer.

We already generate the code to a tempfile most of the time,
only overwrite the target when we have to.

     object queue. This uses per-cpu ring array to allocate/release
     objects from the pre-allocated object pool. Since the index of ring
     array is a 32bit sequential counter, we can retry to push/pop the

Pull probes updates from Masami Hiramatsu:
 "Cleanups:

   - kprobes: Fixes typo in kprobes samples

   - tracing/eprobes: Remove 'break' after return

  kretprobe/fprobe performance improvements:

   - lib: Introduce new `objpool`, which is a high performance lockless
     object queue. This uses per-cpu ring array to allocate/release
     objects from the pre-allocated object pool.

     Since the index of ring array is a 32bit sequential counter, we can
     retry to push/pop the object pointer from the ring without lock (as
     seq-lock does)

   - lib: Add an objpool test module to test the functionality and
     evaluate the performance under some circumstances

   - kprobes/fprobe: Improve kretprobe and rethook scalability
     performance with objpool.

     This improves both legacy kretprobe and fprobe exit handler (which

 The architecture specific system call tables are updated for
 the added map_shadow_stack() syscall and to remove references
 to the long-gone sys_lookup_dcookie() syscall.

The highlights for the driver support this time are
 
  - Qualcomm platforms gain support for the Qualcomm Secure Execution
    Environment firmware interface to access EFI variables on certain

  - Arm FF-A firmware support gains support for v1.1 specification features,
    in particular notification and memory transaction descriptor changes.
 
  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
    In particular, this contains portions of the treewide conversion to

There are a couple new SoCs that are supported for the first time:
 
  - AMD Pensando Elba is a data processing unit based on Cortex-A72
    CPU cores
 
  - Sophgo makes RISC-V based chips, and we now support the CV1800B
    chip used in the milkv-duo board and the massive sg2042 chip in the
    milkv-pioneer, a 64-core developer workstation.
 
  - Qualcomm Snapdragon 720G (sm7125) is a close relative of
    Snapdragon 7c and gets added with some Xiaomi phones
 
  - Renesas gains support for the R8A779F4 (R-Car S4-8) automotive
    SoC and the RZ/G3S (R9A08G045) embedded SoC.
 
 There are also a bunch of newly supported machines that use
 already supported chips. On the 32-bit side, we have:
 
  - USRobotics USR8200 is a NAS/Firewall/router based on the ancient
    Intel IXP4xx platform
 
  - A couple of machines based on the NXP i.MX5 and i.MX6 platforms
 
  - One machine each for Allwinner V3s, Aspeed AST2600, Microchip
    sama5d29 and ST STM32mp157
 
 The other ones all use arm64 cores on chips from allwinner,
 amlogic, freescale, mediatek, qualcomm and rockchip.

deefd5024f VFIO updates for v6.7
- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
    which allows both larger device image sizes for migration, beyond
    the previous 4GB limit, and also read-ahead support for improved
    migration performance. (Yishai Hadas)
 
  - A new bus master control interface for the CDX bus driver where
    there is no in-band mechanism to toggle device DMA as there is
    through config space on PCI devices. (Nipun Gupta)
 
  - Add explicit alignment directives to vfio data structures to
    reduce the chance of breaking 32-bit userspace.  In most cases
    this is transparent and the remaining cases where data structures
    are padded work within the existing rules for extending data
    structures within vfio.  (Stefan Hajnoczi)
 
  - Resolve a bug in the cdx bus driver noted when compiled with clang
    where missing parenthesis result in the wrong operation.
    (Nathan Chancellor)
 
  - Resolve errors reported by smatch for a function when dealing
    with invalid inputs. (Alex Williamson)
 
  - Add migration support to the mtty vfio/mdev sample driver for
    testing and integration purposes, allowing CI of migration without
    specific hardware requirements.  Also resolve many of the short-
    comings of this driver relative to implementation of the vfio
    interrupt ioctl along the way. (Alex Williamson)

Merge tag 'io_uring-futex-2023-10-30' of git://git.kernel.dk/linux

Pull io_uring futex support from Jens Axboe:
 "This adds support for using futexes through io_uring - first futex
  wake and wait, and then the vectored variant of waiting, futex waitv.

  For both wait/wake/waitv, we support the bitset variant, as the
  'normal' variants can be easily implemented on top of that.

  PI and requeue are not supported through io_uring, just the above
  mentioned parts. This may change in the future, but in the spirit of
  keeping this small (and based on what people have been asking for),
  this is what we currently have.

  Wake support is pretty straight forward, most of the thought has gone
  into the wait side to avoid needing to offload wait operations to a
  blocking context. Instead, we rely on the usual callbacks to retry and
  post a completion event, when appropriate.

  As far as I can recall, the first request for futex support with
  io_uring came from Andres Freund, working on postgres. His aio rework
  of postgres was one of the early adopters of io_uring, and futex
  support was a natural extension for that. This is relevant from both a
  usability point of view, as well as for effiency and performance. In
  Andres's words, for the former:

     Futex wait support in io_uring makes it a lot easier to avoid
     deadlocks in concurrent programs that have their own buffer pool:
     Obviously pages in the application buffer pool have to be locked
     during IO. If the initiator of IO A needs to wait for a held lock
     B, the holder of lock B might wait for the IO A to complete. The
     ability to wait for a lock and IO completions at the same time
     provides an efficient way to avoid such deadlocks

  and in terms of effiency, even without unlocking the full potential
  yet, Andres says:

     Futex wake support in io_uring is useful because it allows for more
     efficient directed wakeups. For some "locks" postgres has queues
     implemented in userspace, with wakeup logic that cannot easily be
     implemented with FUTEX_WAKE_BITSET on a single "futex word"
     (imagine waiting for journal flushes to have completed up to a
     certain point).

     Thus a "lock release" sometimes need to wake up many processes in a
     row. A quick-and-dirty conversion to doing these wakeups via
     io_uring lead to a 3% throughput increase, with 12% fewer context
     switches, albeit in a fairly extreme workload"
