tcp: Fix -Wc23-extensions in tcp_options_write()

Clang warns (or errors with CONFIG_WERROR=y) when CONFIG_TCP_AO is set:

  net/ipv4/tcp_output.c:663:2: error: label at end of compound statement is a C23 extension [-Werror,-Wc23-extensions]
    663 |         }
        |         ^
  1 error generated.

On earlier releases (such as clang-11, the current minimum supported
version for building the kernel) that do not support C23, this was a
hard error unconditionally:

  net/ipv4/tcp_output.c:663:2: error: expected statement
          }
          ^
  1 error generated.

While adding a semicolon after the label would resolve this, it is more
in line with the kernel as a whole to refactor this block into a
standalone function, which means the goto a label construct can just be
replaced with a return statement. Do so to resolve the warning.

tg3: Fix the TX ring stall

The TX ring maintained by the tg3 driver can end up in the state, when it
has packets queued for sending but the NIC hardware is not informed, so no
progress is made. This leads to a multi-second interruption in network
traffic followed by dev_watchdog() firing and resetting the queue.

The specific sequence of steps is:

1. tg3_start_xmit() is called at least once and queues packet(s) without
   updating tnapi->prodmbox (netdev_xmit_more() returns true)
2. tg3_start_xmit() is called with an SKB which causes tg3_tso_bug() to be
   called.
3. tg3_tso_bug() determines that the SKB is too large, ...

        if (unlikely(tg3_tx_avail(tnapi) <= frag_cnt_est)) {

   ... stops the queue, and returns NETDEV_TX_BUSY:

        netif_tx_stop_queue(txq);
        ...
        if (tg3_tx_avail(tnapi) <= frag_cnt_est)
                return NETDEV_TX_BUSY;

4. Since all tg3_tso_bug() call sites directly return, the code updating
   tnapi->prodmbox is skipped.

5. The queue is stuck now. tg3_start_xmit() is not called while the queue
   is stopped. The NIC is not processing new packets because
   tnapi->prodmbox wasn't updated. tg3_tx() is not called by
   tg3_poll_work() because the all TX descriptions that could be freed has
   been freed:

        /* run TX completion thread */
        if (tnapi->hw_status->idx[0].tx_consumer != tnapi->tx_cons) {
                tg3_tx(tnapi);

6. Eventually, dev_watchdog() fires triggering a reset of the queue.

This fix makes sure that the tnapi->prodmbox update happens regardless of
the reason tg3_start_xmit() returned.

tg3: power down device only on SYSTEM_POWER_OFF

Dell R650xs servers hangs on reboot if tg3 driver calls
tg3_power_down.

This happens only if network adapters (BCM5720 for R650xs) were
initialized using SNP (e.g. by booting ipxe.efi).

The actual problem is on Dell side, but this fix allows servers
to come back alive after reboot.

This patch re-fix the issues mentioned by commit 22a825c541d7

Blocking sending message do solve the issues though, but it also

of cdc message sending.

Hence that, this patch allows the cdc message sending but to check the

tcp: Fix SYN option room calculation for TCP-AO.

When building SYN packet in tcp_syn_options(), MSS, TS, WS, and
SACKPERM are used without checking the remaining bytes in the
options area.

To keep that logic as is, we limit the TCP-AO MAC length in
tcp_ao_parse_crypto().  Currently, the limit is calculated as below.

  MAX_TCP_OPTION_SPACE - TCPOLEN_TSTAMP_ALIGNED
                       - TCPOLEN_WSCALE_ALIGNED
                       - TCPOLEN_SACKPERM_ALIGNED

This looks confusing as (1) we pack SACKPERM into the leading
2-bytes of the aligned 12-bytes of TS and (2) TCPOLEN_MSS_ALIGNED
is not used.  Fortunately, the calculated limit is not wrong as
TCPOLEN_SACKPERM_ALIGNED and TCPOLEN_MSS_ALIGNED are the same value.

However, we should use the proper constant in the formula.

  MAX_TCP_OPTION_SPACE - TCPOLEN_MSS_ALIGNED
                       - TCPOLEN_TSTAMP_ALIGNED
                       - TCPOLEN_WSCALE_ALIGNED

tcp: fix fastopen code vs usec TS

David Morley and Neal Cardwell started investigating and Neal pointed

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.

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

Merge branch 'dccp-tcp-relocate-security_inet_conn_request'

Kuniyuki Iwashima says:

====================
dccp/tcp: Relocate security_inet_conn_request().

security_inet_conn_request() reads reqsk's remote address, but it's not
initialised in some places.

Let's make sure the address is set before security_inet_conn_request().

dccp/tcp: Call security_inet_conn_request() after setting IPv6 addresses.

Initially, commit 4237c75c0a35 ("[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 e1adea927080 ("calipso: Allow request sockets to be
relabelled by the lsm.").

Commit 284904aa7946 ("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.

net/smc: fix documentation of buffer sizes

Since commit 833bac7ec392 ("net/smc: Fix setsockopt and sysctl to
specify same buffer size again") the SMC protocol uses its own
default values for the smc.rmem and smc.wmem sysctl variables
which are no longer derived from the TCP IPv4 buffer sizes.

Fixup the kernel documentation to reflect this change, too.

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:

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.

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.

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.

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
     is based on rethook) to be scalable on SMP systems. Even with
     8-threads parallel test, it shows a great scalability improvement

   - Remove unneeded freelist.h which is replaced by objpool

   - objpool: Add maintainers entry for the objpool

   - objpool: Fix to remove unused include header lines"

   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

   hardware requirements. Also resolve many of the short- comings of
   this driver relative to implementation of the vfio interrupt ioctl

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"

Merge tag 'clk-for-linus' of git://git./linux/kernel/git/clk/linux

Pull clk driver updates from Stephen Boyd:
"Herein lies a smallish collection of clk driver updates and some core
  clk framework changes for the merge window. The core framework changes
  are only improving the debugfs interface to allow phase adjustments
  and report which consumers of a clk there are. These are most likely
  only of interest to kernel developers.

  On the clk driver side, it's a ghastly amount of updates with only a
  handful of new clk drivers. We have a couple new clk drivers for
  Qualcomm, per usual, and a driver for Renesas, Amlogic, and TI
  respectively. The updates are spread throughout the clk drivers.

  Some highlights are fixing kunit tests for different configurations
  like lockdep and big-endian, avoiding integer overflow in rate
  settable clks, moving clk_hw_onecell_data to the end of allocations so
  that drivers don't corrupt their private data, and migrating clk
  drivers to the regmap maple tree. Otherwise it's the usual fixes to
  clk drivers that only come along with testing the drivers on real
  hardware.

  New Drivers:
   - Add clock driver for TWL6032
   - Initial support for the Qualcomm SM4450 Global Clock Controller and
     SM4450 RPMh clock controllers
   - Add Camera Clock Controller on Qualcomm SM8550
   - Add support for the Renesas RZ/G3S (R9A08G045) SoC
   - Add Amlogic s4 main clock controller support

Updates:
   - Make clk kunit tests work with lockdep
   - Fix clk gate kunit test for big-endian
   - Convert more than a handful of clk drivers to use regmap maple tree
   - Consider the CLK_FRAC_DIVIDER_ZERO_BASED in fractional divider clk
     implementation
   - Add consumer info to clk debugfs
   - Fix various clk drivers that have clk_hw_onecell_data not at the
     end of an allocation
   - Drop CLK_SET_RATE_PARENT for clocks with fixed-rate GPLLs across a
     variety of Qualcomm IPQ platforms
   - Add missing parent of APCS PLL on Qualcomm IPQ6018
   - Add I2C QUP6 clk on Qualcomm IPQ6018 but mark it critical to avoid
     problems with RPM
   - Implement safe source switching for a53pll and use on Qualcomm
     IPQ5332
   - Add support for Stromer Plus PLLs to Qualcomm clk driver
   - Switch Qualcomm SM8550 Video and GPU clock controllers to use OLE
     PLL configure method
   - Non critical fixes to halt bit checks in Qualcomm clk drivers
   - Add SMMU GDSC for Qualcomm MSM8998
   - Fix possible integer overflow in Qualcomm RCG frequency calculation
     code
   - Remove RPM managed clks from Qualcomm MSM8996 GCC driver
   - Add HFPLL configuration for the three HFPLLs in Qualcomm MSM8976
   - Switch Qualcomm MSM8996 CBF clock driver's remove function to
     return void
   - Fix missing dependency for s4 clock controllers
   - Select MXC_CLK when building in the CLK_IMX8QXP
   - Fixes for error handling paths in i.MX8 ACM driver
   - Move the clocks check in i.MX8 ACM driver in order to log any error
   - Drop the unused return value of clk_imx_acm_detach_pm_domains
   - Drop non-existant IMX8MP_CLK_AUDIOMIX_PDM_ROOT clock
   - Fix error handling in i.MX8MQ clock driver
   - Allow a different LCDIF1 clock parent if DT describes it for
     i.MX6SX
   - Keep the SCU resource table sorted in the i.MX8DXL rsrc driver
   - Move the elcdif PLL clock registration above lcd_clk, as it is its
     parent
   - Correct some ENET specific clocks for i.MX8DXL platform
   - Drop the VPU_UART and VPUCORE from i.MX8QM as latest HW revision
     doesn't have them
   - Remove "de-featured" MLB support from i.MX8QM/QXP/DXL platforms
   - Skip registering clocks owned by Cortex-A partition SCU-based
     platforms
   - Add CAN_1/2 to i.MX8QM and M4_0, PI_0_PWM_0 and PI_0_I2C_0 to
     i.MX8QXP resources"

  that will most likely span several releases. We have started by
  converting external users of struct gpio_chip to accessing the wrapper
  around it - struct gpio_device. This is because the latter is
  reference counted while the former is removed when the provider is
  unbound. We also removed several instances of drivers accessing
  private GPIOLIB structures and including the private header from
  drivers/gpio/.

  To that end you'll see several commits aimed at different subsystems
  (acked by relevant maintainers) as well as two merges from the
  x86/platform tree.

  We'll then rework the locking in GPIOLIB which currently uses a big
  spinlock for many different things and could use becoming more
  fine-grained, especially as it doesn't even get the locking right.
  We'll also use SRCU for protecting the gpio_chip pointer against
  in-kernel hot-unplug crashes similar to what we saw triggered from
  user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
  is still vulnerable to these use-cases. I'm just mentioning the plans
  here, this is not part of this PR.

  You'll see some new instances of using __free(). We've added a
  gpio_device_put cleanup helper similar to the put_device one
  introduced by Peter Zijlstra and used it according to the preferred
  pattern except where it didn't make sense.

  GPIOLIB core:
   - provide interfaces allowing users to retrieve, manage and query the
     reference counted GPIO device instead of accessing the private
     gpio_chip structure
   - replace gpiochip_find() with gpio_device_find()
   - remove unused acpi_get_and_request_gpiod()
   - improve the ignore_interrupt functionality in GPIO ACPI
   - correct notifier return codes in gpiolib-of
   - unexport gpiod_set_transitory() as it's unused outside of core GPIO
     code
   - while there are still external users accessing struct gpio_chip,
     let's make gpiochip_get_desc() public so that they at least use the
     preferred helper
   - improve locking for lookup tables
   - annotate struct linereq with __counted_by
   - improve GPIOLIB docs
   - add an OF quirk for LED trigger sources

  Driver improvements:
   - convert all GPIO drivers with .remove() callbacks to using the new
     variant returning void instead of int
   - stop accessing the GPIOLIB private structures in gpio-mockup,
     i2c-mux-gpio, hte-tegra194, gpio-sim
   - use the recommended pattern for autofree variables in gpio-sim
   - add support for more models to gpio-loongson
   - use a notifier chain to notify other blocks about interrupts in
     gpio-eic-sprd instead of looking up GPIO devices on every interrupt
   - convert gpio-pca953x and gpio-fx6408 to using the maple tree regmap
     cache
   - don't include GPIOLIB internal headers in drivers which don't need
     them
   - move the ingenic NAND quirk into gpiolib-of
   - add an ignore interrupt quirk for Peaq C1010
   - drop static GPIO base from gpio-omap, gpio-f7188x
   - use the preferred device_get_match_data() function in drivers that
     still don't
   - refactor gpio-pca953x: switch to using DEFINE_SIMPLE_DEV_PM_OPS(),
     use cleanup helpers, use dev_err_probe() where it makes sense,
     fully convert to using devres and some other minor tweaks

  DT bindings:
   - add support for a new model to gpio-vf610 and update existing
     properties
   - add support for more loongson models
   - add missing support for imx models that are used but undocumented
   - convert bindings for Intel IXP4xx to schema

  Minor stuff:
   - deprecate gpio-mockup in favor of gpio-sim
   - include missing headers here and there
   - stop using gpiochip_find() in OMAP1 board files
   - minor tweaks in gpio-vf610, gpio-hisi
   - remove unneeded 'extern' specifiers from headers"

dm crypt: account large pages in cc->n_allocated_pages

The commit 5054e778fcd9c ("dm crypt: allocate compound pages if
possible") changed dm-crypt to use compound pages to improve
performance. Unfortunately, there was an oversight: the allocation of
compound pages was not accounted at all. Normal pages are accounted in
a percpu counter cc->n_allocated_pages and dm-crypt is limited to
allocate at most 2% of memory. Because compound pages were not
accounted at all, dm-crypt could allocate memory over the 2% limit.

Fix this by adding the accounting of compound pages, so that memory
consumption of dm-crypt is properly limited.

Pull networking updates from Jakub Kicinski:
"Core & protocols:

   - Support usec resolution of TCP timestamps, enabled selectively by a
     route attribute.

   - Defer regular TCP ACK while processing socket backlog, try to send
     a cumulative ACK at the end. Increase single TCP flow performance
     on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).

   - The Fair Queuing (FQ) packet scheduler:
       - add built-in 3 band prio / WRR scheduling
       - support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
       - improve inactive flow reporting
       - optimize the layout of structures for better cache locality

   - Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
     replacement for the old MD5 option.

   - Add more retransmission timeout (RTO) related statistics to
     TCP_INFO.

   - Support sending fragmented skbs over vsock sockets.

   - Make sure we send SIGPIPE for vsock sockets if socket was
     shutdown().

   - Add sysctl for ignoring lower limit on lifetime in Router
     Advertisement PIO, based on an in-progress IETF draft.

   - Add sysctl to control activation of TCP ping-pong mode.

   - Add sysctl to make connection timeout in MPTCP configurable.

   - Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
     limit the number of wakeups.

   - Support netlink GET for MDB (multicast forwarding), allowing user
     space to request a single MDB entry instead of dumping the entire
     table.

   - Support selective FDB flushing in the VXLAN tunnel driver.

   - Allow limiting learned FDB entries in bridges, prevent OOM attacks.

   - Allow controlling via configfs netconsole targets which were
     created via the kernel cmdline at boot, rather than via configfs at
     runtime.

   - Support multiple PTP timestamp event queue readers with different
     filters.

   - MCTP over I3C.

  BPF:

   - Add new veth-like netdevice where BPF program defines the logic of
     the xmit routine. It can operate in L3 and L2 mode.

   - Support exceptions - allow asserting conditions which should never
     be true but are hard for the verifier to infer. With some extra
     flexibility around handling of the exit / failure:

          https://lwn.net/Articles/938435/

   - Add support for local per-cpu kptr, allow allocating and storing
     per-cpu objects in maps. Access to those objects operates on the
     value for the current CPU.

     This allows to deprecate local one-off implementations of per-CPU
     storage like BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.

   - Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
     for systemd to re-implement the LogNamespace feature which allows
     running multiple instances of systemd-journald to process the logs
     of different services.

   - Enable open-coded task_vma iteration, after maple tree conversion
     made it hard to directly walk VMAs in tracing programs.

   - Add open-coded task, css_task and css iterator support. One of the
     use cases is customizable OOM victim selection via BPF.

   - Allow source address selection with bpf_*_fib_lookup().

dm error: Add support for zoned block devices

dm-error is used in several test cases in the xfstests test suite to
check the handling of IO errors in file systems. However, with several
file systems getting native support for zoned block devices (e.g.
btrfs and f2fs), dm-error's lack of zoned block device support creates
problems as the file system attempts executing zone commands (e.g. a
zone append operation) against a dm-error non-zoned block device,
which causes various issues in the block layer (e.g. WARN_ON
triggers).

This commit adds supports for zoned block devices to dm-error, allowing
a DM device table containing an error target to be exposed as a zoned
block device (if all targets have a compatible zoned model support and
mapping). This is done as follows:
1) Allow passing 2 arguments to an error target, similar to dm-linear:
   a backing device and a start sector. These arguments are optional and
   dm-error retains its characteristics if the arguments are not
   specified.
2) Implement the iterate_devices method so that dm-core can normally
   check the zone support and restrictions (e.g. zone alignment of the
   targets). When the backing device arguments are not specified, the
   iterate_devices method never calls the fn() argument.
When no backing device is specified, as before, we assume that the DM
device is not zoned. When the backing device arguments are specified,
the zoned model of the DM device will depend on the backing device
type:
- If the backing device is zoned and its model and mapping is
   compatible with other targets of the device, the resulting device
   will be zoned, with the dm-error mapped portion always returning
   errors (similar to the default non-zoned case).
- If the backing device is not zoned, then the DM device will not be
   either.

This zone support for dm-error requires the definition of a functional
report_zones operation so that dm_revalidate_zones() can operate
correctly and resources for emulating zone append operations
initialized. This is necessary for cases where dm-error is used to
partially map a device and have an overall correct handling of zone
append. This means that dm-error does not fail report zones operations.

Two changes that are not obvious are included to avoid issues:
1) dm_table_supports_zoned_model() is changed to directly check if
   the backing device of a wildcard target (= dm-error target) is
   zoned. Otherwise, we wouldn't be able to catch the invalid setup of
   dm-error without a backing device (non zoned case) being combined
   with zoned targets.
2) dm_table_supports_dax() is modified to return false if the wildcard
   target is found. Otherwise, when dm-error is set without a backing
   device, we end up with a NULL pointer dereference in
   set_dax_synchronous (dax_dev is NULL). This is consistent with the
   current behavior because dm_table_supports_dax() always returned
   false for targets that do not define the iterate_devices method.

dm delay: for short delays, use kthread instead of timers and wq

DM delay's current design of using timers and wq to realize the delays
is insufficient for delays below ~50ms.

This commit enhances the design to use a kthread to flush the expired
delays, trading some CPU time (in some cases) for better delay
accuracy and delays closer to what the user requested for smaller
delays. The new design is chosen as long as all the delays are below
50ms.

Since bios can't be completed in interrupt context using a kthread
is probably the most reasonable way to approach this.

Testing with
echo "0 2097152 zero" | dmsetup create dm-zeros
for i in $(seq 0 20);
do
  echo "0 2097152 delay /dev/mapper/dm-zeros 0 $i" | dmsetup create dm-delay-${i}ms;
done

Some performance numbers for comparison, on beaglebone black (single
core) CONFIG_HZ_1000=y:

fio --name=1msread --rw=randread --bs=4k --runtime=60 --time_based \
    --filename=/dev/mapper/dm-delay-1ms

    --time_based --filename=/dev/mapper/dm-delay-10ms
Theoretical maximum: 100 IOPS
Previous: 90 IOPS
Kthread: 100 IOPS

(This one is just to prove the new design isn't impacting throughput,
not really about delays):
