To get the best stacktrace output, you can compile your userspace
programs with frame pointers (at least glibc + the app you are tracing).

1, export "CC = gcc -fno-omit-frame-pointer";
2, compile your programs with "CC";
3, use uprobe to get stacktrace output.

...

1. Use common arch_stack_walk() infrastructure to avoid duplicated code
   and avoid taking care of the stack storage and filtering.
2. Add sched_ra (means sched return address) and sched_cfa (means sched
   call frame address) to thread_info, and store them in switch_to().
3. Add __get_wchan() implementation.

Now we can print the process stack and wait channel by cat /proc/*/stack
and /proc/*/wchan.

It unwind the stack frame based on prologue code analyze.
CONFIG_KALLSYMS is needed, at least the address and length
of each function.

Three stages when we do unwind,
  1) unwind_start(), the prapare of unwinding, fill unwind_state.
  2) unwind_done(), judge whether the unwind process is finished or not.
  3) unwind_next_frame(), unwind the next frame.

Dividing unwinder helps to add new unwinders in the future, e.g.:
unwinder_frame, unwinder_orc, .etc.

Name "guess unwinder" comes from x86, it scans the stack and reports
every kernel text address it finds.

Unwinders can be used by dump_stack() and other stacktrace functions.

Three stages when we do unwind,
  1) unwind_start(), the prapare of unwinding, fill unwind_state.
  2) unwind_done(), judge whether the unwind process is finished or not.
  3) unwind_next_frame(), unwind the next frame.

Add get_stack_info() to get stack info. At present we have irq stack and
task stack. The next_sp is the key info between two types of stacks.

Dividing unwinder helps to add new unwinders in the future.

Parse MADT to get multi-processor information, in order to fix the boot
problem and cpu-hotplug problem for SMP platform.
Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>

The kernel entry points of both boot CPU (i.e., kernel_entry) and non-
boot CPUs (i.e., smpboot_entry) may be physical address from BootLoader
(in DA mode or identity-mapping PG mode). So we should jump to the link
address before PG enabled (because DA is disabled at the same time) and
just after DMW configured.

Specifically: With some older firmwares, non-boot CPUs started with PG
enabled, but this need firmware cooperation in the form of a temporary
page table, which is deemed unnecessary. OTOH, latest firmware versions
configure the non-boot CPUs to start in DA mode, so kernel-side changes
are needed.

 "Including fixes from bluetooth, bpf, can and netfilter.

  A little larger than usual but it's all fixes, no late features. It's
  large partially because of timing, and partially because of follow ups
  to stuff that got merged a week or so before the merge window and
  wasn't as widely tested. Maybe the Bluetooth fixes are a little
  alarming so we'll address that, but the rest seems okay and not scary.

  Notably we're including a fix for the netfilter Kconfig [1], your WiFi
  warning [2] and a bluetooth fix which should unblock syzbot [3].

  Current release - regressions:

   - Bluetooth:
      - don't try to cancel uninitialized works [3]
      - L2CAP: fix use-after-free caused by l2cap_chan_put

   - tls: rx: fix device offload after recent rework

   - devlink: fix UAF on failed reload and leftover locks in mlxsw

  Current release - new code bugs:

   - netfilter:
      - flowtable: fix incorrect Kconfig dependencies [1]
      - nf_tables: fix crash when nf_trace is enabled

   - bpf:
      - use proper target btf when exporting attach_btf_obj_id
      - arm64: fixes for bpf trampoline support

      - ISO: fix info leak in iso_sock_getsockopt()
      - ISO: fix iso_sock_getsockopt for BT_DEFER_SETUP
      - ISO: fix memory corruption on iso_pinfo.base
      - ISO: fix not using the correct QoS
      - hci_conn: fix updating ISO QoS PHY

   - phy: dp83867: fix get nvmem cell fail

  Previous releases - regressions:

   - wifi: cfg80211: fix validating BSS pointers in
     __cfg80211_connect_result [2]

   - atm: bring back zatm uAPI after ATM had been removed

   - properly fix old bug making bonding ARP monitor mode not being able
     to work with software devices with lockless Tx

   - tap: fix null-deref on skb->dev in dev_parse_header_protocol

   - revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps some
     devices and breaks others

   - netfilter:
      - nf_tables: many fixes rejecting cross-object linking which may
        lead to UAFs
      - nf_tables: fix null deref due to zeroed list head
      - nf_tables: validate variable length element extension

   - bgmac: fix a BUG triggered by wrong bytes_compl

   - bcmgenet: indicate MAC is in charge of PHY PM

  Previous releases - always broken:

   - bpf:
      - fix bad pointer deref in bpf_sys_bpf() injected via test infra
      - disallow non-builtin bpf programs calling the prog_run command
      - don't reinit map value in prealloc_lru_pop
      - fix UAFs during the read of map iterator fd
      - fix invalidity check for values in sk local storage map
      - reject sleepable program for non-resched map iterator

   - mptcp:

      - do not queue data on closed subflows

   - virtio_net: fix memory leak inside XDP_TX with mergeable

   - vsock: fix memory leak when multiple threads try to connect()

   - rework sk_user_data sharing to prevent psock leaks

   - geneve: fix TOS inheriting for ipv4

   - tunnels & drivers: do not use RT_TOS for IPv6 flowlabel

area_cache_get() is used to distribute cache->area and set cache->id,
 and if cache->id is not 0 and cache->area->kref refcount is 0, it will
 release the cache->area by nfp_cpp_area_release(). area_cache_get()
 set cache->id before cpp->op->area_init() and nfp_cpp_area_acquire().

But if area_init() or nfp_cpp_area_acquire() fails, the cache->id is
 is already set but the refcount is not increased as expected. At this
 time, calling the nfp_cpp_area_release() will cause use-after-free.

To avoid the use-after-free, set cache->id after area_init() and
 nfp_cpp_area_acquire() complete successfully.

Note: This vulnerability is triggerable by providing emulated device
 equipped with specified configuration.

This reverts commit 258fafcd.

The clang -Wformat warning is terminally broken, and the clang people
can't seem to get their act together.

This test program causes a warning with clang:

	#include <stdio.h>

	int main(int argc, char **argv)
	{
		printf("%hhu\n", 'a');
	}

resulting in

  t.c:5:19: warning: format specifies type 'unsigned char' but the argument has type 'int' [-Wformat]
          printf("%hhu\n", 'a');
                  ~~~~     ^~~
                  %d

and apparently clang people consider that a feature, because they don't
want to face the reality of how either C character constants, C
arithmetic, and C varargs functions work.

The rest of the world just shakes their head at that kind of
incompetence, and turns off -Wformat for clang again.

And no, the "you should use a pointless cast to shut this up" is not a
valid answer.  That warning should not exist in the first place, or at
least be optinal with some "-Wformat-me-harder" kind of option.

[ Admittedly, there's also very little reason to *ever* use '%hh[ud]' in
  C, but what little reason there is is entirely about 'I want to see
  only the low 8 bits of the argument'. So I would suggest nobody ever
  use that format in the first place, but if they do, the clang
  behavious is simply always wrong. Because '%hhu' takes an 'int'. It's
  that simple. ]

Commit b32d4582 ("dm bufio: Add DM_BUFIO_CLIENT_NO_SLEEP flag")
added a "NO_SLEEP" mode, it replaces a mutex with a spinlock, and it
is only usable when the device is in read-only mode (because the write
path may be sleeping while holding the dm_bufio_client lock).

However, there are still two points where the code could sleep even in
read-only mode. One is in __get_unclaimed_buffer -> __make_buffer_clean.
The other is in __try_evict_buffer -> __make_buffer_clean. These functions
will call __make_buffer_clean which sleeps if the buffer is being read.

Fix these cases so that if c->no_sleep is set __make_buffer_clean
will not be called and the buffer will be skipped instead.
