f8fa5d7692 cred: switch to using atomic_long_t
There are multiple ways to grab references to credentials, and the only
protection we have against overflowing it is the memory required to do
so.

With memory sizes only moving in one direction, let's bump the reference
count to 64-bit and move it outside the realm of feasibly overflowing.

595e52284d io_uring/poll: don't enable lazy wake for POLLEXCLUSIVE
There are a few quirks around using lazy wake for poll unconditionally,
and one of them is related the EPOLLEXCLUSIVE. Those may trigger
exclusive wakeups, which wake a limited number of entries in the wait
queue. If that wake number is less than the number of entries someone is
waiting for (and that someone is also using DEFER_TASKRUN), then we can
get stuck waiting for more entries while we should be processing the ones
we already got.

If we're doing exclusive poll waits, flag the request as not being
compatible with lazy wakeups.

4376807bf2 mm/mglru: reclaim offlined memcgs harder
In the effort to reduce zombie memcgs [1], it was discovered that the
memcg LRU doesn't apply enough pressure on offlined memcgs.  Specifically,
instead of rotating them to the tail of the current generation
(MEMCG_LRU_TAIL) for a second attempt, it moves them to the next
generation (MEMCG_LRU_YOUNG) after the first attempt.

Not applying enough pressure on offlined memcgs can cause them to build
up, and this can be particularly harmful to memory-constrained systems.

On Pixel 8 Pro, launching apps for 50 cycles:
                 Before  After  Change

8aa4206179 mm/mglru: respect min_ttl_ms with memcgs
While investigating kswapd "consuming 100% CPU" [1] (also see "mm/mglru:
try to stop at high watermarks"), it was discovered that the memcg LRU can
breach the thrashing protection imposed by min_ttl_ms.

Before the memcg LRU:
  kswapd()
    shrink_node_memcgs()
      mem_cgroup_iter()
        inc_max_seq()  // always hit a different memcg
    lru_gen_age_node()
      mem_cgroup_iter()
        check the timestamp of the oldest generation

After the memcg LRU:
  kswapd()
    shrink_many()
      restart:
        iterate the memcg LRU:
          inc_max_seq()  // occasionally hit the same memcg
          if raced with lru_gen_rotate_memcg():
            goto restart
    lru_gen_age_node()
      mem_cgroup_iter()
        check the timestamp of the oldest generation

Specifically, when the restart happens in shrink_many(), it needs to stick
with the (memcg LRU) generation it began with.  In other words, it should
neither re-read memcg_lru->seq nor age an lruvec of a different
generation.  Otherwise it can hit the same memcg multiple times without
giving lru_gen_age_node() a chance to check the timestamp of that memcg's
oldest generation (against min_ttl_ms).

081488051d mm/mglru: fix underprotected page cache
Unmapped folios accessed through file descriptors can be underprotected. 
Those folios are added to the oldest generation based on:

1. The fact that they are less costly to reclaim (no need to walk the
   rmap and flush the TLB) and have less impact on performance (don't
   cause major PFs and can be non-blocking if needed again).
2. The observation that they are likely to be single-use. E.g., for
   client use cases like Android, its apps parse configuration files
   and store the data in heap (anon); for server use cases like MySQL,
   it reads from InnoDB files and holds the cached data for tables in
   buffer pools (anon).

However, the oldest generation can be very short lived, and if so, it
doesn't provide the PID controller with enough time to respond to a surge
of refaults.  (Note that the PID controller uses weighted refaults and
those from evicted generations only take a half of the whole weight.) In
other words, for a short lived generation, the moving average smooths out
the spike quickly.

To fix the problem:
1. For folios that are already on LRU, if they can be beyond the
   tracking range of tiers, i.e., five accesses through file
   descriptors, move them to the second oldest generation to give them
   more time to age. (Note that tiers are used by the PID controller
   to statistically determine whether folios accessed multiple times
   through file descriptors are worth protecting.)
2. When adding unmapped folios to LRU, adjust the placement of them so
   that they are not too close to the tail. The effect of this is
   similar to the above.

On Android, launching 55 apps sequentially:
                           Before     After      Change

6376a82459 mm/damon/core: make damon_start() waits until kdamond_fn() starts
The cleanup tasks of kdamond threads including reset of corresponding
DAMON context's ->kdamond field and decrease of global nr_running_ctxs
counter is supposed to be executed by kdamond_fn().  However, commit
0f91d13366 ("mm/damon: simplify stop mechanism") made neither
damon_start() nor damon_stop() ensure the corresponding kdamond has
started the execution of kdamond_fn().

As a result, the cleanup can be skipped if damon_stop() is called fast
enough after the previous damon_start().  Especially the skipped reset
of ->kdamond could cause a use-after-free.

Fix it by waiting for start of kdamond_fn() execution from
damon_start().

d3bb89ea9c mm: fix VMA heap bounds checking
After converting selinux to VMA heap check helper, the gcl triggers an
execheap SELinux denial, which is caused by a changed logic check.

Previously selinux only checked that the VMA range was within the VMA heap
range, and the implementation checks the intersection between the two
ranges, but the corner case (vm_end=start_brk, brk=vm_start) isn't handled
correctly.

Since commit 11250fd12e ("mm: factor out VMA stack and heap checks") was
only a function extraction, it seems that the issue was introduced by
commit 0db0c01b53 ("procfs: fix /proc/<pid>/maps heap check").  Let's
fix above corner cases, meanwhile, correct the wrong indentation of the
stack and heap check helpers.

718ab82266 PCI/ASPM: Add pci_enable_link_state_locked()
Add pci_enable_link_state_locked() for enabling link states that can be
used in contexts where a pci_bus_sem read lock is already held (e.g. from
pci_walk_bus()).

This helper will be used to fix a couple of potential deadlocks where
the current helper is called with the lock already held, hence the CC
stable tag.

125f1c7f26 net/sched: act_ct: Take per-cb reference to tcf_ct_flow_table
The referenced change added custom cleanup code to act_ct to delete any
callbacks registered on the parent block when deleting the
tcf_ct_flow_table instance. However, the underlying issue is that the
drivers don't obtain the reference to the tcf_ct_flow_table instance when
registering callbacks which means that not only driver callbacks may still
be on the table when deleting it but also that the driver can still have
pointers to its internal nf_flowtable and can use it concurrently which
results either warning in netfilter[0] or use-after-free.

Fix the issue by taking a reference to the underlying struct
tcf_ct_flow_table instance when registering the callback and release the
reference when unregistering. Expose new API required for such reference
counting by adding two new callbacks to nf_flowtable_type and implementing
them for act_ct flowtable_ct type. This fixes the issue by extending the
lifetime of nf_flowtable until all users have unregistered.

a6adef8987 ARM: SoC fixes for v6.7
Most of the changes are devicetree fixes for NXP, Mediatek, Rockchips
 Arm machines as well as Microchip RISC-V, and most of these address
 build-time warnings for spec violations and other minor issues. One of
 the Mediatek warnings was enabled by default and prevented a clean build.
 The ones that address serious runtime issues are all on the i.MX platform:
 
  - a boot time panic on imx8qm
  - USB hanging under load on imx8
  - regressions on the imx93 ethernet phy
 
 Code fixes include a minor error handling for the i.MX PMU driver, and
 a number of firmware driver fixes:
 
  - OP-TEE fix for supplicant based device enumeration, and a new
    sysfs attribute to needed to fix a race against userspace
 
  - Arm SCMI fix for possible truncation/overflow in the frequency
    computations
 
  - Multiple FF-A fixes for the newly added notification support.

Merge tag 'soc-fixes-6.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC fixes from Arnd Bergmann:
 "Most of the changes are devicetree fixes for NXP, Mediatek, Rockchips
  Arm machines as well as Microchip RISC-V, and most of these address
  build-time warnings for spec violations and other minor issues. One of
  the Mediatek warnings was enabled by default and prevented a clean
  build.

  The ones that address serious runtime issues are all on the i.MX
  platform:

   - a boot time panic on imx8qm

   - USB hanging under load on imx8

   - regressions on the imx93 ethernet phy

  Code fixes include a minor error handling for the i.MX PMU driver, and
  a number of firmware driver fixes:

   - OP-TEE fix for supplicant based device enumeration, and a new sysfs
     attribute to needed to fix a race against userspace

   - Arm SCMI fix for possible truncation/overflow in the frequency
     computations

   - Multiple FF-A fixes for the newly added notification support"

bd4a816752 net: ipv6: support reporting otherwise unknown prefix flags in RTM_NEWPREFIX
Lorenzo points out that we effectively clear all unknown
flags from PIO when copying them to userspace in the netlink
RTM_NEWPREFIX notification.

We could fix this one at a time as new flags are defined,
or in one fell swoop - I choose the latter.

We could either define 6 new reserved flags (reserved1..6) and handle
them individually (and rename them as new flags are defined), or we
could simply copy the entire unmodified byte over - I choose the latter.

This unfortunately requires some anonymous union/struct magic,
so we add a static assert on the struct size for a little extra safety.

Ido Schimmel
e03781879a drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group
The "NET_DM" generic netlink family notifies drop locations over the
"events" multicast group. This is problematic since by default generic
netlink allows non-root users to listen to these notifications.

Fix by adding a new field to the generic netlink multicast group
structure that when set prevents non-root users or root without the
'CAP_SYS_ADMIN' capability (in the user namespace owning the network
namespace) from joining the group. Set this field for the "events"
group. Use 'CAP_SYS_ADMIN' rather than 'CAP_NET_ADMIN' because of the
nature of the information that is shared over this group.

Note that the capability check in this case will always be performed
against the initial user namespace since the family is not netns aware
and only operates in the initial network namespace.

A new field is added to the structure rather than using the "flags"
field because the existing field uses uAPI flags and it is inappropriate
to add a new uAPI flag for an internal kernel check. In net-next we can
rework the "flags" field to use internal flags and fold the new field
into it. But for now, in order to reduce the amount of changes, add a
new field.

Since the information can only be consumed by root, mark the control
plane operations that start and stop the tracing as root-only using the
'GENL_ADMIN_PERM' flag.

Tested using [1].

 # capsh -- -c ./dm_repo
 # capsh --drop=cap_sys_admin -- -c ./dm_repo

187da0f825 hugetlb: fix null-ptr-deref in hugetlb_vma_lock_write
The routine __vma_private_lock tests for the existence of a reserve map
associated with a private hugetlb mapping.  A pointer to the reserve map
is in vma->vm_private_data.  __vma_private_lock was checking the pointer
for NULL.  However, it is possible that the low bits of the pointer could
be used as flags.  In such instances, vm_private_data is not NULL and not
a valid pointer.  This results in the null-ptr-deref reported by syzbot:

general protection fault, probably for non-canonical address 0xdffffc000000001d:

4b7de80160 bpf: Fix prog_array_map_poke_run map poke update
Lee pointed out issue found by syscaller [0] hitting BUG in prog array
map poke update in prog_array_map_poke_run function due to error value
returned from bpf_arch_text_poke function.

There's race window where bpf_arch_text_poke can fail due to missing
bpf program kallsym symbols, which is accounted for with check for
-EINVAL in that BUG_ON call.

The problem is that in such case we won't update the tail call jump
and cause imbalance for the next tail call update check which will
fail with -EBUSY in bpf_arch_text_poke.

I'm hitting following race during the program load:

  CPU 0                             CPU 1

  bpf_prog_load
    bpf_check
      do_misc_fixups
        prog_array_map_poke_track

                                    map_update_elem
                                      bpf_fd_array_map_update_elem
                                        prog_array_map_poke_run

                                          bpf_arch_text_poke returns -EINVAL

    bpf_prog_kallsyms_add

After bpf_arch_text_poke (CPU 1) fails to update the tail call jump, the next
poke update fails on expected jump instruction check in bpf_arch_text_poke
with -EBUSY and triggers the BUG_ON in prog_array_map_poke_run.

Similar race exists on the program unload.

Fixing this by moving the update to bpf_arch_poke_desc_update function which
makes sure we call __bpf_arch_text_poke that skips the bpf address check.

Each architecture has slightly different approach wrt looking up bpf address
in bpf_arch_text_poke, so instead of splitting the function or adding new
'checkip' argument in previous version, it seems best to move the whole
map_poke_run update as arch specific code.

This extra check doesn't work for a handshake when SYN segment has
(current_key.maclen != rnext_key.maclen). It could be amended to
preserve rnext_key.maclen instead of current_key.maclen, but that
requires a lookup on listen socket.

Originally, this extra maclen check was introduced just because it was
cheap. Drop it and convert tcp_request_sock::maclen into boolean
tcp_request_sock::used_tcp_ao.

e0f04e41e8 drm/atomic-helpers: Invoke end_fb_access while owning plane state
Invoke drm_plane_helper_funcs.end_fb_access before
drm_atomic_helper_commit_hw_done(). The latter function hands over
ownership of the plane state to the following commit, which might
free it. Releasing resources in end_fb_access then operates on undefined
state. This bug has been observed with non-blocking commits when they
are being queued up quickly.

Here is an example stack trace from the bug report. The plane state has
been free'd already, so the pages for drm_gem_fb_vunmap() are gone.

Unable to handle kernel paging request at virtual address 0000000100000049

 drm_atomic_helper_commit_tail+0x90/0xa0
 commit_tail+0x15c/0x188
 commit_work+0x14/0x20

Fix this by running end_fb_access immediately after updating all planes
in drm_atomic_helper_commit_planes(). The existing clean-up helper
drm_atomic_helper_cleanup_planes() now only handles cleanup_fb.

For aborted commits, roll back from drm_atomic_helper_prepare_planes()
in the new helper drm_atomic_helper_unprepare_planes(). This case is
different from regular cleanup, as we have to release the new state;
regular cleanup releases the old state. The new helper also invokes
cleanup_fb for all planes.

The changes mostly involve DRM's atomic helpers. Only two drivers, i915
and nouveau, implement their own commit function. Update them to invoke
drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail
function do not require changes.

v4:
	* fix documentation (kernel test robot)
v3:
	* add drm_atomic_helper_unprepare_planes() for rolling back
	* use correct state for end_fb_access
v2:
	* fix test in drm_atomic_helper_cleanup_planes()

58d3aade20 tcp: fix mid stream window clamp.
After the blamed commit below, if the user-space application performs
window clamping when tp->rcv_wnd is 0, the TCP socket will never be
able to announce a non 0 receive window, even after completely emptying
the receive buffer and re-setting the window clamp to higher values.

Refactor tcp_set_window_clamp() to address the issue: when the user
decreases the current clamp value, set rcv_ssthresh according to the
same logic used at buffer initialization, but ensuring reserved mem
provisioning.

To avoid code duplication factor-out the relevant bits from
tcp_adjust_rcv_ssthresh() in a new helper and reuse it in the above
scenario.

When increasing the clamp value, give the rcv_ssthresh a chance to grow
according to previously implemented heuristic.

The VA addresses are coming from rdma-core in this diagram can be
arbitrary, but for 64k pages, the VA may be offset by some number of HCA
4k pages and followed by some number of HCA 4k pages.

The current iterator doesn't account for either the preceding 4k pages or
the following 4k pages.

Fix the issue by extending the ib_block_iter to contain the number of DMA
pages like comment [1] says and by using __sg_advance to start the
iterator at the first live HCA page.

The changes are contained in a parallel set of iterator start and next
functions that are umem aware and specific to umem since there is one user
of the rdma_for_each_block() without umem.

These two fixes prevents the extra pages before and after the user MR
data.

Fix the preceding pages by using the __sq_advance field to start at the
first 4k page containing MR data.

Fix the following pages by saving the number of pgsz blocks in the
iterator state and downcounting on each next.

This fix allows for the elimination of the small page crutch noted in the
Fixes.

Fixes: 10c75ccb54 ("RDMA/umem: Prevent small pages from being returned by ib_umem_find_best_pgsz()")

c55e0a55b1 fuse: Rename DIRECT_IO_RELAX to DIRECT_IO_ALLOW_MMAP
Although DIRECT_IO_RELAX's initial usage is to allow shared mmap, its
description indicates a purpose of reducing memory footprint. This
may imply that it could be further used to relax other DIRECT_IO
operations in the future.

Replace it with a flag DIRECT_IO_ALLOW_MMAP which does only one thing,
allow shared mmap of DIRECT_IO files while still bypassing the cache
on regular reads and writes.

[Miklos] Also Keep DIRECT_IO_RELAX definition for backward compatibility.

17b17be28d VFIO fixes for v6.7-rc4
- Fix the lifecycle of a mutex in the pds variant driver such that
    a reset prior to opening the device won't find it uninitialized.
    Implement the release path to symmetrically destroy the mutex.
    Also switch a different lock from spinlock to mutex as the code
    path has the potential to sleep and doesn't need the spinlock
    context otherwise. (Brett Creeley)
 
  - Fix an issue detected via randconfig where KVM tries to symbol_get
    an undeclared function.  The symbol is temporarily declared
    unconditionally here, which resolves the problem and avoids churn
    relative to a series pending for the next merge window which
    resolves some of this symbol ugliness, but also fixes Kconfig
    dependencies. (Sean Christopherson)

669fc83452 Probes fixes for v6.7-r3:
- objpool: Fix objpool overrun case on memory/cache access delay especially
   on the big.LITTLE SoC. The objpool uses a copy of object slot index
   internal loop, but the slot index can be changed on another processor
   in parallel. In that case, the difference of 'head' local copy and the
   'slot->last' index will be bigger than local slot size. In that case,
   we need to re-read the slot::head to update it.
 
 - kretprobe: Fix to use appropriate rcu API for kretprobe holder. Since
   kretprobe_holder::rp is RCU managed, it should use rcu_assign_pointer()
   and rcu_dereference_check() correctly. Also adding __rcu tag for
   finding wrong usage by sparse.
 
 - rethook: Fix to use appropriate rcu API for rethook::handler. The same
   as kretprobe, rethook::handler is RCU managed and it should use
   rcu_assign_pointer() and rcu_dereference_check(). This also adds __rcu
