791c8ab095 bcachefs bugfixes for 6.7
Lots of small fixes for minor nits and compiler warnings. Bigger items:
 
  - The six locks lost wakeup is finally fixed: six_read_trylock() was
    checking for the waiting bit before decrementing the number of
    readers - validated the fix with a torture test.
 
  - Fix for a memory reclaim issue: when needing to reallocate a key
    cache key, we now do our usual GFP_NOWAIT; unlock(); GFP_KERNEL
    dance.
 
  - Multiple deleted inodes btree fixes
 
  - Fix an issue in fsck, where i_nlink would be recalculated incorrectly
    for hardlinked files if a snapshot had ever been taken.
 
  - Kill journal pre-reservations: This is a bigger patch than I would
    normally send at this point, but it deletes code and it fixes some of
    our tests that would sporadically die with the journal getting stuck,
    and it's a performance improvement, too.

6ba5b61383 drm/amdgpu: add a module parameter to control the AGP aperture
Add a module parameter to control the AGP aperture.  The AGP
aperture is an aperture in the GPU's internal address space
which provides direct non-paged access to the platform address
space.  This access is non-snooped so only uncached memory
can be accessed.

Add a knob so that we can toggle this for debugging.

If it is cleared unexpectedly, driver will

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Remove unused variable causing compilation warning in nft_set_rbtree,
   from Yang Li. This unused variable is a left over from previous
   merge window.

2) Possible return of uninitialized in nf_conntrack_bridge, from
   Linkui Xiao. This is there since nf_conntrack_bridge is available.

3) Fix incorrect pointer math in nft_byteorder, from Dan Carpenter.
   Problem has been there since 2016.

4) Fix bogus error in destroy set element command. Problem is there
   since this new destroy command was added.

5) Fix race condition in ipset between swap and destroy commands and
   add/del/test control plane. This problem is there since ipset was
   merged.

6) Split async and sync catchall GC in two function to fix unsafe
   iteration over RCU. This is a fix-for-fix that was included in
   the previous pull request.

7e1caeace0 macvlan: Don't propagate promisc change to lower dev in passthru
Macvlan device in passthru mode sets its lower device promiscuous mode
according to its MACVLAN_FLAG_NOPROMISC flag instead of synchronizing it to
its own promiscuity setting. However, macvlan_change_rx_flags() function
doesn't check the mode before propagating such changes to the lower device
which can cause net_device->promiscuity counter overflow as illustrated by
reproduction example [0] and resulting dmesg log [1]. Fix the issue by
first verifying the mode in macvlan_change_rx_flags() function before
propagating promiscuous mode change to the lower device.

[0]:
ip link add macvlan1 link enp8s0f0 type macvlan mode passthru
ip link set macvlan1 promisc on
ip l set dev macvlan1 up
ip link set macvlan1 promisc off
ip l set dev macvlan1 down
ip l set dev macvlan1 up

7cd5af0e93 net: sched: do not offload flows with a helper in act_ct
There is no hardware supporting ct helper offload. However, prior to this
patch, a flower filter with a helper in the ct action can be successfully
set into the HW, for example (eth1 is a bnxt NIC):

  # tc qdisc add dev eth1 ingress_block 22 ingress
  # tc filter add block 22 proto ip flower skip_sw ip_proto tcp \
    dst_port 21 ct_state -trk action ct helper ipv4-tcp-ftp
  # tc filter show dev eth1 ingress

    filter block 22 protocol ip pref 49152 flower chain 0 handle 0x1
      eth_type ipv4
      ip_proto tcp
      dst_port 21
      ct_state -trk
      skip_sw
      in_hw in_hw_count 1   <----
        action order 1: ct zone 0 helper ipv4-tcp-ftp pipe
         index 2 ref 1 bind 1
        used_hw_stats delayed

This might cause the flower filter not to work as expected in the HW.

This patch avoids this problem by simply returning -EOPNOTSUPP in
tcf_ct_offload_act_setup() to not allow to offload flows with a helper
in act_ct.

Treat the operation as an error case when the return value is equivalent to

buffer, making the string malformed and should not be used. Provide a
string with only the firmware version when forming the string with the

dce9414284 net/mlx5e: Reduce the size of icosq_str
icosq_str size is unnecessarily too long, and it causes a build warning
-Wformat-truncation with W=1. Looking closely, It doesn't need to be 255B,
hence this patch reduces the size to 32B which should be more than enough
to host the string: "ICOSQ: 0x%x, ".

While here, add a missing space in the formatted string.

This fixes the following build warning:

92214be597 net/mlx5e: Update doorbell for port timestamping CQ before the software counter
Previously, mlx5e_ptp_poll_ts_cq would update the device doorbell with the
incremented consumer index after the relevant software counters in the
kernel were updated. In the mlx5e_sq_xmit_wqe context, this would lead to
either overrunning the device CQ or exceeding the expected software buffer
size in the device CQ if the device CQ size was greater than the software
buffer size. Update the relevant software counter only after updating the
device CQ consumer index in the port timestamping napi_poll context.

Log:

7e3f3ba97e net/mlx5e: Track xmit submission to PTP WQ after populating metadata map
Ensure the skb is available in metadata mapping to skbs before tracking the
metadata index for detecting undelivered CQEs. If the metadata index is put
in the tracking list before putting the skb in the map, the metadata index
might be used for detecting undelivered CQEs before the relevant skb is
available in the map, which can lead to a null-ptr-deref.
