7e2cd21e02 TTY/Serial driver fixes for 6.0-rc7
Here are some small, and late, serial driver fixes for 6.0-rc7 to
 resolve some reported problems.
 
 Included in here are:
 	- tegra icount accounting fixes, including a framework function
 	  that other drivers will be converted over to using in 6.1-rc1.
 	- fsl_lpuart reset bugfix
 	- 8250 omap 485 bugfix
 	- sifive serial clock bugfix
 
 The last 3 patches have not shown up in linux-next due to them being
 added to my tree only 2 days ago, but they are tiny and self-contained
 and the developers say they resolve issues that they have with 6.0-rc.
 The other 3 have been in linux-next for a while with no reported issues.

- Fix false positive "sleeping while atomic" warning resulting from
   the kPTI rework taking a mutex too early.
 
 - Fix possible overflow in AMU frequency calculation
 
 - Fix incorrect shift in CMN PMU driver which causes problems with
   newer versions of the IP
 
 - Reduce alignment of the CFI jump table to avoid huge kernel images
   and link errors with !4KiB page size configurations

1707c39ae3 Driver core fixes for 6.0-rc7
Here are two tiny driver core fixes for 6.0-rc7 that resolve some
 oft-reported problems.
 
 The first is a revert of the "fw_devlink.strict=1" default option that
 we keep trying to enable, but we keep finding platforms that this just
 breaks everything on.  So again, we need it reverted and hopefully it
 can be worked on in future releases.
 
 The second is a sysfs file-size bugfix that resolves an issue that many
 people are starting to hit as the fix it is fixing also was backported
 to stable kernels.  The util-linux developers are starting to get
 bugreports about sysfs files that contain no data because of this
 problem, and this fix which has been in linux-next in the bitfield tree
 for a long time, resolves it.  I'm submitting it here as it needs to be
 merged for 6.0-final, not for 6.1-rc1.
 
 Both of these have been in linux-next with no reported issues, only
 reports were that these fixed problems.

13b0566962 vmlinux.lds.h: CFI: Reduce alignment of jump-table to function alignment
Due to undocumented, hysterical raisins on x86, the CFI jump-table
sections in .text are needlessly aligned to PMD_SIZE in the vmlinux
linker script. When compiling a CFI-enabled arm64 kernel with a 64KiB
page-size, a PMD maps 512MiB of virtual memory and so the .text section
increases to a whopping 940MiB and blows the final Image up to 960MiB.
Others report a link failure.

Since the CFI jump-table requires only instruction alignment, reduce the
alignment directives to function alignment for parity with other parts
of the .text section. This reduces the size of the .text section for the
aforementioned 64KiB page size arm64 kernel to 19MiB for a much more
reasonable total Image size of 39MiB.

  - A fix for the interrupt number on at91/lan966 ethernet PHYs
 
  - A second round of fixes for NXP i.MX series, including a couple
    of build issues, and board specific DT corrections on
    TQMa8MPQL, imx8mp-venice-gw74xx and imx8mm-verdin for reliability
    and partially broken functionality.
 
  - Several fixes for Rockchip SoCs, addressing a USB issue on BPI-R2-Pro,
    wakeup on Gru-Bob and reliability of high-speed SD cards, among
    other minor issues.
 
  - A fix for a long-running naming mistake that prevented the moxart mmc
    driver from working at all.
 
  - Multiple Arm SCMI firmware fixes for hardening some corner cases.

504c25cb76 Including fixes from wifi, netfilter and can.
A handful of awaited fixes here - revert of the FEC changes,
 bluetooth fix, fixes for iwlwifi spew.
 
 We added a warning in PHY/MDIO code which is triggering on
 a couple of platforms in a false-positive-ish way. If we can't
 iron that out over the week we'll drop it and re-add for 6.1.
 
 I've added a new "follow up fixes" section for fixes to fixes
 in 6.0-rcs but it may actually give the false impression that
 those are problematic or that more testing time would have
 caught them. So likely a one time thing.
 
 Follow up fixes:
 
  - nf_tables_addchain: fix nft_counters_enabled underflow
 
  - ebtables: fix memory leak when blob is malformed
 
  - nf_ct_ftp: fix deadlock when nat rewrite is needed
 
 Current release - regressions:
 
  - Revert "fec: Restart PPS after link state change"
  - Revert "net: fec: Use a spinlock to guard `fep->ptp_clk_on`"
 
  - Bluetooth: fix HCIGETDEVINFO regression
 
  - wifi: mt76: fix 5 GHz connection regression on mt76x0/mt76x2
 
  - mptcp: fix fwd memory accounting on coalesce
 
  - rwlock removal fall out:
    - ipmr: always call ip{,6}_mr_forward() from RCU read-side
      critical section
    - ipv6: fix crash when IPv6 is administratively disabled
 
  - tcp: read multiple skbs in tcp_read_skb()
 
  - mdio_bus_phy_resume state warning fallout:
    - eth: ravb: fix PHY state warning splat during system resume
    - eth: sh_eth: fix PHY state warning splat during system resume
 
 Current release - new code bugs:

7ebb5f8e00 Revert "iommu/vt-d: Fix possible recursive locking in intel_iommu_init()"
This reverts commit 9cd4f14344.

Some issues were reported on the original commit. Some thunderbolt devices
don't work anymore due to the following DMA fault.

DMAR: DRHD: handling fault status reg 2
DMAR: [INTR-REMAP] Request device [09:00.0] fault index 0x8080
      [fault reason 0x25]
      Blocked a compatibility format interrupt request

Bring it back for now to avoid functional regression.

9cd4f14344 iommu/vt-d: Fix possible recursive locking in intel_iommu_init()
The global rwsem dmar_global_lock was introduced by commit 3a5670e8ac
("iommu/vt-d: Introduce a rwsem to protect global data structures"). It
is used to protect DMAR related global data from DMAR hotplug operations.

The dmar_global_lock used in the intel_iommu_init() might cause recursive
locking issue, for example, intel_iommu_get_resv_regions() is taking the
dmar_global_lock from within a section where intel_iommu_init() already
holds it via probe_acpi_namespace_devices().

Using dmar_global_lock in intel_iommu_init() could be relaxed since it is
unlikely that any IO board must be hot added before the IOMMU subsystem is
initialized. This eliminates the possible recursive locking issue by moving
down DMAR hotplug support after the IOMMU is initialized and removing the
uses of dmar_global_lock in intel_iommu_init().

e35be05d74 Driver core fixes for 6.0-rc5
Here are some small driver core and debugfs fixes for 6.0-rc5.
 
 Included in here are:
   - multiple attempts to get the arch_topology code to work properly on
     non-cluster SMT systems.  First attempt caused build breakages in
     linux-next and 0-day, second try worked.
   - debugfs fixes for a long-suffering memory leak.  The pattern of
     debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
     add debugfs_lookup_and_remove() to fix this problem.  Also fix up
     the scheduler debug code that highlighted this problem.  Fixes for
     other subsystems will be trickling in over the next few months for
     this same issue once the debugfs function is merged.
 
 All of these have been in linux-next since Wednesday with no reported
 problems.

Merge tag 'driver-core-6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core fixes from Greg KH:
 "Here are some small driver core and debugfs fixes for 6.0-rc5.

  Included in here are:

   - multiple attempts to get the arch_topology code to work properly on
     non-cluster SMT systems. First attempt caused build breakages in
     linux-next and 0-day, second try worked.

   - debugfs fixes for a long-suffering memory leak. The pattern of
     debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
     add debugfs_lookup_and_remove() to fix this problem. Also fix up
     the scheduler debug code that highlighted this problem. Fixes for
     other subsystems will be trickling in over the next few months for
     this same issue once the debugfs function is merged.

  All of these have been in linux-next since Wednesday with no reported
  problems"

Many bug fixes in several drivers:
 
 - Fix misuse of the DMA API in rtrs
 
 - Several irdma issues: hung task due to SQ flushing, incorrect capability
   reporting to userspace, improper error handling for MW corners, touching
   an uninitialized SGL for during invalidation.
 
 - hns was using the wrong page size limits for the HW, an incorrect
   calculation of wqe_shift causing WQE corruption, and mis computed
   a timer id.
 
 - Fix a crash in SRP triggered by blktests
 
 - Fix compiler errors by calling virt_to_page() with the proper type in
   siw
 
 - Userspace triggerable deadlock in ODP
 
 - mlx5 could use the wrong profile due to some driver loading races,
   counters were not working in some device configurations, and a crash on
   error unwind.

2f79cdfe58 fs: only do a memory barrier for the first set_buffer_uptodate()
Commit d4252071b9 ("add barriers to buffer_uptodate and
set_buffer_uptodate") added proper memory barriers to the buffer head
BH_Uptodate bit, so that anybody who tests a buffer for being up-to-date
will be guaranteed to actually see initialized state.

However, that commit didn't _just_ add the memory barrier, it also ended
up dropping the "was it already set" logic that the BUFFER_FNS() macro
had.

That's conceptually the right thing for a generic "this is a memory
barrier" operation, but in the case of the buffer contents, we really
only care about the memory barrier for the _first_ time we set the bit,
in that the only memory ordering protection we need is to avoid anybody
seeing uninitialized memory contents.

Any other access ordering wouldn't be about the BH_Uptodate bit anyway,
and would require some other proper lock (typically BH_Lock or the folio
lock).  A reader that races with somebody invalidating the buffer head
isn't an issue wrt the memory ordering, it's a serialization issue.

Now, you'd think that the buffer head operations don't matter in this
day and age (and I certainly thought so), but apparently some loads
still end up being heavy users of buffer heads.  In particular, the
kernel test robot reported that not having this bit access optimization
in place caused a noticeable direct IO performance regression on ext4:

  fxmark.ssd_ext4_no_jnl_DWTL_54_directio.works/sec -26.5% regression

although you presumably need a fast disk and a lot of cores to actually
notice.

9cb252c4c1 net: skb: export skb drop reaons to user by TRACE_DEFINE_ENUM
As Eric reported, the 'reason' field is not presented when trace the
kfree_skb event by perf:

$ perf record -e skb:kfree_skb -a sleep 10
$ perf script
  ip_defrag 14605 [021]   221.614303:   skb:kfree_skb:
  skbaddr=0xffff9d2851242700 protocol=34525 location=0xffffffffa39346b1
  reason:

The cause seems to be passing kernel address directly to TP_printk(),
which is not right. As the enum 'skb_drop_reason' is not exported to
user space through TRACE_DEFINE_ENUM(), perf can't get the drop reason
string from the 'reason' field, which is a number.

Therefore, we introduce the macro DEFINE_DROP_REASON(), which is used
to define the trace enum by TRACE_DEFINE_ENUM(). With the help of
DEFINE_DROP_REASON(), now we can remove the auto-generate that we
introduced in the commit ec43908dd5
("net: skb: use auto-generation to convert skb drop reason to string"),
and define the string array 'drop_reasons'.

Hmmmm...now we come back to the situation that have to maintain drop
reasons in both enum skb_drop_reason and DEFINE_DROP_REASON. But they
are both in dropreason.h, which makes it easier.

After this commit, now the format of kfree_skb is like this:

$ cat /tracing/events/skb/kfree_skb/format
name: kfree_skb
ID: 1524
format:
        field:unsigned short common_type;       offset:0;       size:2; signed:0;

Remove the CONFIG_PREEMPT_RT symbol from the ifdef around
do_softirq_own_stack() and move it to Kconfig instead.

Enable softirq stacks based on SOFTIRQ_ON_OWN_STACK which depends on
HAVE_SOFTIRQ_ON_OWN_STACK and its default value is set to !PREEMPT_RT.
This ensures that softirq stacks are not used on PREEMPT_RT and avoids
a 'select' statement on an option which has a 'depends' statement.

9ca05b0f27 RDMA/mlx5: Rely on RoCE fw cap instead of devlink when setting profile
When the RDMA auxiliary driver probes, it sets its profile based on
devlink driverinit value. The latter might not be in sync with FW yet
(In case devlink reload is not performed), thus causing a mismatch
between RDMA driver and FW. This results in the following FW syndrome
when the RDMA driver tries to adjust RoCE state, which fails the probe:

"0xC1F678 | modify_nic_vport_context: roce_en set on a vport that
doesn't support roce"

To prevent this, select the PF profile based on FW RoCE capability
instead of relying on devlink driverinit value.
To provide backward compatibility of the RoCE disable feature, on older
FW's where roce_rw is not set (FW RoCE capability is read-only), keep
the current behavior e.g., rely on devlink driverinit value.

2aec909912 wifi: use struct_group to copy addresses
We sometimes copy all the addresses from the 802.11 header
for the AAD, which may cause complaints from fortify checks.
Use struct_group() to avoid the compiler warnings/errors.

====================
netfilter: bug fixes for net

1. Fix IP address check in irc DCC conntrack helper, this should check
   the opposite direction rather than the destination address of the
   packets' direction, from David Leadbeater.

2. bridge netfilter needs to drop dst references, from Harsh Modi.
   This was fine back in the day the code was originally written,
   but nowadays various tunnels can pre-set metadata dsts on packets.

3. Remove nf_conntrack_helper sysctl and the modparam toggle, users
   need to explicitily assign the helpers to use via nftables or
   iptables.  Conntrack helpers, by design, may be used to add dynamic
   port redirections to internal machines, so its necessary to restrict
   which hosts/peers are allowed to use them.
   It was discovered that improper checking in the irc DCC helper makes
   it possible to trigger the 'please do dynamic port forward'
   from outside by embedding a 'DCC' in a PING request; if the client
   echos that back a expectation/port forward gets added.
   The auto-assign-for-everything mechanism has been in "please don't do this"
   territory since 2012.  From Pablo.

4. Fix a memory leak in the netdev hook error unwind path, also from Pablo.

 - A single fix for over-eager retries for networking (Pavel)

 - Revert the notification slot support for zerocopy sends.

   It turns out that even after more than a year or development and
   testing, there's not full agreement on whether just using plain
   ordered notifications is Good Enough to avoid the complexity of using
   the notifications slots. Because of that, we decided that it's best
   left to a future final decision.

   We can always bring back this feature, but we can't really change it
   or remove it once we've released 6.0 with it enabled. The reverts
   leave the usual CQE notifications as the primary interface for
   knowing when data was sent, and when it was acked. (Pavel)

c7943bb324 drm/edid: Handle EDID 1.4 range descriptor h/vfreq offsets
EDID 1.4 introduced some extra flags in the range
descriptor to support min/max h/vfreq >= 255. Consult them
to correctly parse the vfreq limits.

Note that some combinations of the flags are documented
as "reserved" (as are some other values in the descriptor)
but explicitly checking for those doesn't seem particularly
worthwile since we end up with bogus results whether we
decode them or not.

v2: Increase the storage to u16 to make it work (Jani)
    Note the "reserved" values situation (Jani)
v3: Document the EDID version number in the defines
    Drop some bogus (u8) casts

spi: mux: Fix mux interaction with fast path optimisations
The spi-mux driver is rather too clever and attempts to resubmit any
message that is submitted to it to the parent controller with some
adjusted callbacks.  This does not play at all nicely with the fast
path which now sets flags on the message indicating that it's being
handled through the fast path, we see async messages flagged as being on
the fast path.  Ideally the spi-mux code would duplicate the message but
that's rather invasive and a bit fragile in that it relies on the mux
knowing which fields in the message to copy.  Instead teach the core
that there are controllers which can't cope with the fast path and have
the mux flag itself as being such a controller, ensuring that messages
going via the mux don't get partially handled via the fast path.

This will reduce the performance of any spi-mux connected device since
we'll now always use the thread for both the actual controller and the
mux controller instead of just the actual controller but given that we
were always hitting the slow path anyway it's hopefully not too much of
an additional cost and it allows us to keep the fast path.

David Howells says:

====================
rxrpc fixes
Here are some fixes for AF_RXRPC:

 (1) Fix the handling of ICMP/ICMP6 packets.  This is a problem due to
     rxrpc being switched to acting as a UDP tunnel, thereby allowing it to
     steal the packets before they go through the UDP Rx queue.  UDP
     tunnels can't get ICMP/ICMP6 packets, however.  This patch adds an
     additional encap hook so that they can.

 (2) Fix the encryption routines in rxkad to handle packets that have more
     than three parts correctly.  The problem is that ->nr_frags doesn't
     count the initial fragment, so the sglist ends up too short.

 (3) Fix a problem with destruction of the local endpoint potentially
     getting repeated.

 (4) Fix the calculation of the time at which to resend.
     jiffies_to_usecs() gives microseconds, not nanoseconds.

 (5) Fix AFS to work out when callback promises and locks expire based on
     the time an op was issued rather than the time the first reply packet
     arrives.  We don't know how long the server took between calculating
     the expiry interval and transmitting the reply.

 (6) Given (5), rxrpc_get_reply_time() is no longer used, so remove it.
