Reset controller fixes for v5.16, part 2

Fix pm_runtime_resume_and_get() error handling in the

Because of commit 9cb2ff11 ("spi: cadence-quadspi: Disable Auto-HW polling"),
which does a write to the CQSPI_REG_WR_COMPLETION_CTRL register
regardless of any condition. Well, the Cadence QuadSPI controller on
Intel's SoCFPGA platforms does not implement the
CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register
results in a crash!

So starting with v5.16, I introduced the patch
98d948eb ("spi: cadence-quadspi: fix write completion support"),
which adds the dts compatible "intel,socfpga-qspi" that is specific for
versions that doesn't have the CQSPI_REG_WR_COMPLETION_CTRL register implemented.

v3: revert back to "intel,socfpga-qspi"
v2: use both "cdns,qspi-nor" and "cdns,qspi-nor-0010"

The QSPI controller on Intel's SoCFPGA platform does not implement the
CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register
results in a crash.

Introduce the dts compatible "intel,socfpga-qspi" to differentiate the
hardware.

DAMON debugfs interface iterates current monitoring targets in
'dbgfs_target_ids_read()' while holding the corresponding
'kdamond_lock'.  However, it also destructs the monitoring targets in
'dbgfs_before_terminate()' without holding the lock.  This can result in
a use_after_free bug.  This commit avoids the race by protecting the
destruction with the corresponding 'kdamond_lock'.

It is not easily reproducible, but on 5.16-rc I have several times hit
the VM_BUG_ON_PAGE(PageTail(page), page) in
page_cache_add_speculative(): usually from filemap_get_read_batch() for
an ext4 read, yesterday from next_uptodate_page() from
filemap_map_pages() for a shmem fault.

That BUG used to be placed where page_ref_add_unless() had succeeded,
but now it is placed before folio_ref_add_unless() is attempted: that is
not safe, since it is only the acquired reference which makes the page
safe from racing THP collapse or split.

We could keep the BUG, checking PageTail only when
folio_ref_try_add_rcu() has succeeded; but I don't think it adds much
value - just delete it.

When a memory error hits a tail page of a free hugepage,
__page_handle_poison() is expected to be called to isolate the error in
4kB unit, but it's not called due to the outdated if-condition in
memory_failure_hugetlb().  This loses the chance to isolate the error in
the finer unit, so it's not optimal.  Drop the condition.

This "(p != head && TestSetPageHWPoison(head)" condition is based on the
old semantics of PageHWPoison on hugepage (where PG_hwpoison flag was
set on the subpage), so it's not necessray any more.  By getting to set
PG_hwpoison on head page for hugepages, concurrent error events on
different subpages in a single hugepage can be prevented by
TestSetPageHWPoison(head) at the beginning of memory_failure_hugetlb().
So dropping the condition should not reopen the race window originally
mentioned in commit b985194c ("hwpoison, hugetlb:
lock_page/unlock_page does not match for handling a free hugepage")

When booting with crashkernel= on the kernel command line a warning
similar to

    Kernel command line: ro console=ttyS0 crashkernel=256M
    Unknown kernel command line parameters "crashkernel=256M", will be passed to user space.

is printed.

This comes from crashkernel= being parsed independent from the kernel
parameter handling mechanism.  So the code in init/main.c doesn't know
that crashkernel= is a valid kernel parameter and prints this incorrect
warning.

Suppress the warning by adding a dummy early_param handler for
crashkernel=.

alloc_pages_vma() may try to allocate THP page on the local NUMA node
first:

	page = __alloc_pages_node(hpage_node,
		gfp | __GFP_THISNODE | __GFP_NORETRY, order);

And if the allocation fails it retries allowing remote memory:

	if (!page && (gfp & __GFP_DIRECT_RECLAIM))
    		page = __alloc_pages_node(hpage_node,
					gfp, order);

However, this retry allocation completely ignores memory policy nodemask
allowing allocation to escape restrictions.

The first appearance of this bug seems to be the commit ac5b2c18
("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings").

The bug disappeared later in the commit 89c83fb5 ("mm, thp:
consolidate THP gfp handling into alloc_hugepage_direct_gfpmask") and
reappeared again in slightly different form in the commit 76e654cc
("mm, page_alloc: allow hugepage fallback to remote nodes when
madvised")

Fix this by passing correct nodemask to the __alloc_pages() call.

I find that we can easily reproduce this problem with the following
commands:

	cat /sys/kernel/debug/kfence/objects
	echo scan > /sys/kernel/debug/kmemleak
	cat /sys/kernel/debug/kmemleak

The leaked memory is allocated in the stack below:

    do_syscall_64
      do_sys_open
        do_dentry_open
          full_proxy_open
            seq_open            ---> alloc seq_file
      vfs_read
        full_proxy_read
          seq_read
            seq_read_iter
              traverse          ---> alloc seq_buf

And it should have been released in the following process:

    do_syscall_64
      syscall_exit_to_user_mode
        exit_to_user_mode_prepare
          task_work_run
            ____fput
              __fput
                full_proxy_release  ---> free here

However, the release function corresponding to file_operations is not
implemented in kfence.  As a result, a memory leak occurs.  Therefore,
the solution to this problem is to implement the corresponding release
function.

There are some chances that the actual base of hardware is different
from the value recorded by driver, so we have to reset the variable
of ocp_base to sync it.

Set ocp_base to -1. Then, it would be updated and the new base would be
set to the hardware next time.

Commit 561d8352 ("bridge: use ndo_siocdevprivate") changed the
source and destination arguments of copy_{to,from}_user in bridge's
old_deviceless() from args[1] to uarg breaking SIOC{G,S}IFBR ioctls.

Commit cbd7ad29 ("net: bridge: fix ioctl old_deviceless bridge

BRCTL_GET_BRIDGES one untouched.

The fixes BRCTL_GET_BRIDGES as well and has been tested with busybox's
brctl.

Example of broken brctl:
$ brctl show

brctl: can't get bridge name for index 0: No such device or address

Example of fixed brctl:

For Ocelot switches, the CPU injected frames have an injection header
where it can specify the QoS class of the packet and the DSA tag, now it
uses the SKB priority to set that. If a traffic class to priority
mapping is configured on the netdevice (with mqprio for example ...), it
won't be considered for CPU injected headers. This patch make the QoS
class aligned to the priority to traffic class mapping if it exists.

After commit d3256efd ("veth: allow enabling NAPI even without XDP"),
if GRO is enabled on a veth device and TSO is disabled on the peer
device, TCP skbs will go through the NAPI callback. If there is no XDP
program attached, the veth code does not perform any share check, and
shared/cloned skbs could enter the GRO engine.
