spi: axi-spi-engine improvements
Merge series from David Lechner <dlechner@baylibre.com>:
We are working towards adding support for the offload feature[1] of the
AXI SPI Engine IP core. Before we can do that, we want to make some
general fixes and improvements to the driver. In order to avoid a giant
series with 35+ patches, we are splitting this up into a few smaller
series.
This first series mostly doing some housekeeping:
* Convert device tree bindings to yaml.
* Add a MAINTAINERS entry.
* Clean up probe and remove using devm.
* Separate message state from driver state.
* Add support for cs_off and variable word size.
Once this series is applied, we will follow up with a second series of
general improvements, and then finally a 3rd series that implements the
offload support. The offload support will also involve the IIO
subsystem (a new IIO driver will depend on the new SPI offload feature),
so I'm mentioning this now in case we want to do anything ahead of time
to prepare for that (e.g. putting all of these changes on a separate
branch).

spi: axi-spi-engine: add support for any word size
The AXI SPI Engine IP supports any word size from 1 to 32 bits. This
adds support for this by setting the bits_per_word_mask and emitting
the appropriate instruction to the SPI Engine each time a transfer
requires a new word size.
The functions that transfer tx/rx buffers from/to the SPI Engine
registers (spi_engine_write_{tx,rx}_fifo()) as well as the function that
creates the transfer instruction (spi_engine_gen_xfer()) also have to be
modified to take into account the word size since xfer->len is the
size of the buffers in bytes rather than words.

spi: axi-spi-engine: remove struct spi_engine::msg
In the AXI SPI Engine driver, the struct spi_engine::msg member was used
to keep track of the current message being processed. The SPI core is
already keeping track of this, so we don't need to duplicate the effort.
In most cases, we already have a pointer to the current message, so we
can pass it directly to the functions that need it. In the one case
where we don't have a pointer to the current message, we can get it
from struct spi_controller::cur_msg.

spi: axi-spi-engine: move msg state to new struct
This moves the message state in the AXI SPI Engine driver to a new
struct spi_engine_msg_state.
Previously, the driver state contained various pointers that pointed
to memory owned by a struct spi_message. However, it did not set any of
these pointers to NULL when a message was completed. This could lead to
use after free bugs.
Example of how this could happen:
1. SPI core calls into spi_engine_transfer_one_message() with msg1.
2. Assume something was misconfigured and spi_engine_tx_next() is not
called enough times in interrupt callbacks for msg1 such that
spi_engine->tx_xfer is never set to NULL before the msg1 completes.
3. SYNC interrupt is received and spi_finalize_current_message() is
called for msg1. spi_engine->msg is set to NULL but no other
message-specific state is reset.
4. Caller that sent msg1 is notified of the completion and frees msg1
and the associated xfers and tx/rx buffers.
4. SPI core calls into spi_engine_transfer_one_message() with msg2.
5. When spi_engine_tx_next() is called for msg2, spi_engine->tx_xfer is
still be pointing to an xfer from msg1, which was already freed.
spi_engine_xfer_next() tries to access xfer->transfer_list of one
of the freed xfers and we get a segfault or undefined behavior.
To avoid issues like this, instead of putting per-message state in the
driver state struct, we can make use of the struct spi_message::state
field to store a pointer to a new struct spi_engine_msg_state. This way,
all of the state that belongs to specific message stays with that
message and we don't have to remember to manually reset all aspects of
the message state when a message is completed. Rather, a new state is
allocated for each message.
Most of the changes are just renames where the state is accessed. One
place where this wasn't straightforward was the sync_id member. This
has been changed to use ida_alloc_range() since we needed to separate
the per-message sync_id from the per-controller next available sync_id.

NFSD: Fix checksum mismatches in the duplicate reply cache
nfsd_cache_csum() currently assumes that the server's RPC layer has
been advancing rq_arg.head[0].iov_base as it decodes an incoming
request, because that's the way it used to work. On entry, it
expects that buf->head[0].iov_base points to the start of the NFS
header, and excludes the already-decoded RPC header.
These days however, head[0].iov_base now points to the start of the
RPC header during all processing. It no longer points at the NFS
Call header when execution arrives at nfsd_cache_csum().
In a retransmitted RPC the XID and the NFS header are supposed to
be the same as the original message, but the contents of the
retransmitted RPC header can be different. For example, for krb5,
the GSS sequence number will be different between the two. Thus if
the RPC header is always included in the DRC checksum computation,
the checksum of the retransmitted message might not match the
checksum of the original message, even though the NFS part of these
messages is identical.
The result is that, even if a matching XID is found in the DRC,
the checksum mismatch causes the server to execute the
retransmitted RPC transaction again.

NFSD: Fix "start of NFS reply" pointer passed to nfsd_cache_update()
The "statp + 1" pointer that is passed to nfsd_cache_update() is
supposed to point to the start of the egress NFS Reply header. In
fact, it does point there for AUTH_SYS and RPCSEC_GSS_KRB5 requests.
But both krb5i and krb5p add fields between the RPC header's
accept_stat field and the start of the NFS Reply header. In those
cases, "statp + 1" points at the extra fields instead of the Reply.
The result is that nfsd_cache_update() caches what looks to the
client like garbage.
A connection break can occur for a number of reasons, but the most
common reason when using krb5i/p is a GSS sequence number window
underrun. When an underrun is detected, the server is obliged to
drop the RPC and the connection to force a retransmit with a fresh
GSS sequence number. The client presents the same XID, it hits in
the server's DRC, and the server returns the garbage cache entry.
The "statp + 1" argument has been used since the oldest changeset
in the kernel history repo, so it has been in nfsd_dispatch()
literally since before history began. The problem arose only when
the server-side GSS implementation was added twenty years ago.

dm-bufio: fix no-sleep mode
dm-bufio has a no-sleep mode. When activated (with the
DM_BUFIO_CLIENT_NO_SLEEP flag), the bufio client is read-only and we
could call dm_bufio_get from tasklets. This is used by dm-verity.
Unfortunately, commit
450e8dee51aa ("dm bufio: improve concurrent IO
performance") broke this and the kernel would warn that cache_get()
was calling down_read() from no-sleeping context. The bug can be
reproduced by using "veritysetup open" with the "--use-tasklets"
flag.
This commit fixes dm-bufio, so that the tasklet mode works again, by
expanding use of the 'no_sleep_enabled' static_key to conditionally
use either a rw_semaphore or rwlock_t (which are colocated in the
buffer_tree structure using a union).

dm-delay: fix a race between delay_presuspend and delay_bio
In delay_presuspend, we set the atomic variable may_delay and then stop
the timer and flush pending bios. The intention here is to prevent the
delay target from re-arming the timer again.
However, this test is racy. Suppose that one thread goes to delay_bio,
sees that dc->may_delay is one and proceeds; now, another thread executes
delay_presuspend, it sets dc->may_delay to zero, deletes the timer and
flushes pending bios. Then, the first thread continues and adds the bio to
delayed->list despite the fact that dc->may_delay is false.
Fix this bug by changing may_delay's type from atomic_t to bool and
only access it while holding the delayed_bios_lock mutex. Note that we
don't have to grab the mutex in delay_resume because there are no bios
in flight at this point.

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

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

modpost: fix section mismatch message for RELA
The section mismatch check prints a bogus symbol name on some
architectures.
[test code]
#include <linux/init.h>
int __initdata foo;
int get_foo(void) { return foo; }
If you compile it with GCC for riscv or loongarch, modpost will show an
incorrect symbol name:
WARNING: modpost: vmlinux: section mismatch in reference: get_foo+0x8 (section: .text) -> done (section: .init.data)
To get the correct symbol address, the st_value must be added.
This issue has never been noticed since commit
93684d3b8062 ("kbuild:
include symbol names in section mismatch warnings") presumably because
st_value becomes zero on most architectures when the referenced symbol
is looked up. It is not true for riscv or loongarch, at least.
With this fix, modpost will show the correct symbol name:
WARNING: modpost: vmlinux: section mismatch in reference: get_foo+0x8 (section: .text) -> foo (section: .init.data)

====================
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.

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

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.
