Pull drm fixes from Dave Airlie:
"Bit quieter this week, the main thing is it pulls in the fixes for the
sysfb resource issue you were seeing. these had been queued for next
so should have had some decent testing.
Otherwise amdgpu, i915 and msm each have a few fixes, and vc4 has one.
fbdev:
- sysfb fixes/conflicting fb fixes
amdgpu:
- GPU recovery fix
- Fix integer type usage in fourcc header for AMD modifiers
- KFD TLB flush fix for gfx9 APUs
- Display fix
i915:
- Fix ioctl argument error return
- Fix d3cold disable to allow PCI upstream bridge D3 transition
- Fix setting cache_dirty for dma-buf objects on discrete
msm:
- Fix to increment vsync_cnt before calling drm_crtc_handle_vblank so
that userspace sees the value *after* it is incremented if waiting
for vblank events
- Fix to reset drm_dev to NULL in dp_display_unbind to avoid a crash
in probe/bind error paths
- Fix to resolve the smatch error of de-referencing before NULL check
in dpu_encoder_phys_wb.c
- Fix error return to userspace if fence-id allocation fails in
submit ioctl
vc4:
- NULL ptr dereference fix"

We have two options:
1. Treat all BPF_LSM_CGROUP the same, regardless of attach_btf_id
2. Treat BPF_LSM_CGROUP+attach_btf_id as a separate hook point
I was doing (2) in the original patch, but switching to (1) here:
* bpf_prog_query returns all attached BPF_LSM_CGROUP programs
regardless of attach_btf_id
* attach_btf_id is exported via bpf_prog_info

Allow attaching to lsm hooks in the cgroup context.
Attaching to per-cgroup LSM works exactly like attaching
to other per-cgroup hooks. New BPF_LSM_CGROUP is added
to trigger new mode; the actual lsm hook we attach to is
signaled via existing attach_btf_id.
For the hooks that have 'struct socket' or 'struct sock' as its first
argument, we use the cgroup associated with that socket. For the rest,
we use 'current' cgroup (this is all on default hierarchy == v2 only).
Note that for some hooks that work on 'struct sock' we still
take the cgroup from 'current' because some of them work on the socket
that hasn't been properly initialized yet.
Behind the scenes, we allocate a shim program that is attached
to the trampoline and runs cgroup effective BPF programs array.
This shim has some rudimentary ref counting and can be shared
between several programs attaching to the same lsm hook from
different cgroups.
Note that this patch bloats cgroup size because we add 211
cgroup_bpf_attach_type(s) for simplicity sake. This will be
addressed in the subsequent patch.
Also note that we only add non-sleepable flavor for now. To enable
sleepable use-cases, bpf_prog_run_array_cg has to grab trace rcu,
shim programs have to be freed via trace rcu, cgroup_bpf.effective
should be also trace-rcu-managed + maybe some other changes that
I'm not aware of.

Kernel uapi headers are supposed to use __[us]{8,16,32,64} types defined
by <linux/types.h> as opposed to 'uint32_t' and similar. See [1] for the
relevant discussion about this topic. In this particular case, the usage
of 'uint64_t' escaped headers_check as these macros are not being called
here. However, the following program triggers a compilation error:
#include <drm/drm_fourcc.h>
int main()
{
unsigned long x = AMD_FMT_MOD_CLEAR(RB);

}
gcc error:

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:
(linux-5.19-rc2$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
@@
identifier S, member, array;
type T1, T2;
@@
struct S {
...
T1 member;
T2 array[
- 0
];
};
-fstrict-flex-arrays=3 is coming and we need to land these changes
to prevent issues like these in the short future:
../fs/minix/dir.c:337:3: warning: 'strcpy' will always overflow; destination buffer has size 0,
but the source string has length 2 (including NUL byte) [-Wfortify-source]
strcpy(de3->name, ".");
^
Since these are all [0] to [] changes, the risk to UAPI is nearly zero. If
this breaks anything, we can use a union with a new member name.

When the target process is busy, incoming oneway transactions are
queued in the async_todo list. If the clients continue sending extra
oneway transactions while the target process is frozen, this queue can
become too large to accommodate new transactions. That's why binder
driver introduced ONEWAY_SPAM_DETECTION to detect this situation. It's
helpful to debug the async binder buffer exhausting issue, but the
issue itself isn't solved directly.
In real cases applications are designed to send oneway transactions
repeatedly, delivering updated inforamtion to the target process.
Typical examples are Wi-Fi signal strength and some real time sensor
data. Even if the apps might only care about the lastet information,
all outdated oneway transactions are still accumulated there until the
frozen process is thawed later. For this kind of situations, there's
no existing method to skip those outdated transactions and deliver the
latest one only.
This patch introduces a new transaction flag TF_UPDATE_TXN. To use it,
use apps can set this new flag along with TF_ONE_WAY. When such an
oneway transaction is to be queued into the async_todo list of a frozen
process, binder driver will check if any previous pending transactions
can be superseded by comparing their code, flags and target node. If
such an outdated pending transaction is found, the latest transaction
will supersede that outdated one. This effectively prevents the async
binder buffer running out and saves unnecessary binder read workloads.

Add support for RS-485 multipoint addressing using 9th bit [*]. The
addressing mode is configured through ->rs485_config().
ADDRB in termios indicates 9th bit addressing mode is enabled. In this
mode, 9th bit is used to indicate an address (byte) within the
communication line. ADDRB can only be enabled/disabled through
->rs485_config() that is also responsible for setting the destination and
receiver (filter) addresses.
Add traps to detect unwanted changes to struct serial_rs485 layout using
static_assert().
[*] Technically, RS485 is just an electronic spec and does not itself
specify the 9th bit addressing mode but 9th bit seems at least
"semi-standard" way to do addressing with RS485.

In some cases, the NX hugepage mitigation for iTLB multihit is not
needed for all guests on a host. Allow disabling the mitigation on a
per-VM basis to avoid the performance hit of NX hugepages on trusted
workloads.
In order to disable NX hugepages on a VM, ensure that the userspace
actor has permission to reboot the system. Since disabling NX hugepages
would allow a guest to crash the system, it is similar to reboot
permissions.
Ideally, KVM would require userspace to prove it has access to KVM's
nx_huge_pages module param, e.g. so that userspace can opt out without
needing full reboot permissions. But getting access to the module param
file info is difficult because it is buried in layers of sysfs and module
glue. Requiring CAP_SYS_BOOT is sufficient for all known use cases.

The MLO links used for connection with an MLD AP are decided by the
driver in case of SME offloaded to driver.
Add support for the drivers to indicate the information of links used
for MLO connection in connect and roam callbacks, update the connected
links information in wdev from connect/roam result sent by driver.
Also, send the connected links information to userspace.
Add a netlink flag attribute to indicate that userspace supports
handling of MLO connection. Drivers must not do MLO connection when this
flag is not set. This is to maintain backwards compatibility with older
supplicant versions which doesn't have support for MLO connection.

For authentication, we need the BSS, the link_id and the AP
MLD address to create the link and station, (for now) the
driver assigns a link address and sends the frame, the MLD
address needs to be the address of the interface.
For association, pass the list of BSSes that were selected
for the MLO connection, along with extra per-STA profile
elements, the AP MLD address and the link ID on which the
association request should be sent.
Note that for now we don't have a proper way to pass the link
address(es) and so the driver/mac80211 will select one, but
depending on how that selection works it means that assoc w/o
auth data still being around (mac80211 implementation detail)
the association won't necessarily work - so this will need to
be extended in the future to sort out the link addressing.

In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.
So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.
For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.
Also included in this patch is some refactoring of the data
structures in struct wireless_dev, splitting for the first
time the data into type dependent pieces, to make reasoning
about these things easier.

The new helpers bpf_tcp_raw_{gen,check}_syncookie_ipv{4,6} allow an XDP
program to generate SYN cookies in response to TCP SYN packets and to
check those cookies upon receiving the first ACK packet (the final
packet of the TCP handshake).
Unlike bpf_tcp_{gen,check}_syncookie these new helpers don't need a
listening socket on the local machine, which allows to use them together
with synproxy to accelerate SYN cookie generation.

all options), and bpf_tcp_check_syncookie accepts lengths bigger than
sizeof(struct tcphdr). Fix the documentation that says these lengths
should be exactly sizeof(struct tcphdr).
While at it, fix a typo in the name of struct ipv6hdr.

A cast inside __builtin_constant_p doesn't do anything since it should
evaluate as constant at compile time irrespective of this cast. Instead,
I moved this cast outside the ternary to ensure the return type is as
expected.
Additionally, if __HAVE_BUILTIN_BSWAP16__ was not defined then __swab16 is
actually returning an `int` not a `u16` due to integer promotion.
As Al Viro notes:
You *can't* get smaller-than-int out of ? :, same as you can't get it
out of addition, etc.
This also fixes some clang -Wformat warnings involving default
argument promotion.

====================
mlx5-next: updates 2022-06-14
1) Updated HW bits and definitions for upcoming features
1.1) vport debug counters
1.2) flow meter
1.3) Execute ASO action for flow entry
1.4) enhanced CQE compression
2) Add ICM header-modify-pattern RDMA API
Leon Says
=========
SW steering manipulates packet's header using "modifying header" actions.
Many of these actions do the same operation, but use different data each time.
Currently we create and keep every one of these actions, which use expensive
and limited resources.
Now we introduce a new mechanism - pattern and argument, which splits
a modifying action into two parts:
1. action pattern: contains the operations to be applied on packet's header,
mainly set/add/copy of fields in the packet
2. action data/argument: contains the data to be used by each operation
in the pattern.
This way we reuse same patterns with different arguments to create new
modifying actions, and since many actions share the same operations, we end
up creating a small number of patterns that we keep in a dedicated cache.
These modify header patterns are implemented as new type of ICM memory,
so the following kernel patch series add the support for this new ICM type.

Add a new KFD ioctl to return the largest possible memory size that
can be allocated as a buffer object using
kfd_ioctl_alloc_memory_of_gpu. It attempts to use exactly the same
accept/reject criteria as that function so that allocating a new
buffer object of the size returned by this new ioctl is guaranteed to
succeed, barring races with other allocating tasks.
This IOCTL will be used by libhsakmt:

HCTR2 is a tweakable, length-preserving encryption mode that is intended
for use on CPUs with dedicated crypto instructions. HCTR2 has the
property that a bitflip in the plaintext changes the entire ciphertext.
This property fixes a known weakness with filename encryption: when two
filenames in the same directory share a prefix of >= 16 bytes, with
AES-CTS-CBC their encrypted filenames share a common substring, leaking
information. HCTR2 does not have this problem.
More information on HCTR2 can be found here: "Length-preserving

* sock_diag: TLS_INFO_ZC_SENDFILE -> TLS_INFO_ZC_RO_TX
RO stands for readonly and emphasizes that the application shouldn't

Commit 6420ac0af95d ("mtdchar: prevent unbounded allocation in MEMWRITE
ioctl") added a safety check to mtdchar_write_ioctl() which attempts to
ensure that the write request sent by user space does not extend beyond
the MTD device's size. However, that check contains an addition of two
struct mtd_write_req fields, 'start' and 'len', both of which are u64
variables. The result of that addition can overflow, allowing the
safety check to be bypassed.
The arguably simplest fix - changing the data types of the relevant
struct mtd_write_req fields - is not feasible as it would break user
space.
Fix by making mtdchar_write_ioctl() truncate the value provided by user
space in the 'len' field of struct mtd_write_req, so that only the lower
32 bits of that field are used, preventing the overflow.
While the 'ooblen' field of struct mtd_write_req is not currently used
in any similarly flawed safety check, also truncate it to 32 bits, for
consistency with the 'len' field and with other MTD routines handling
OOB data.
Update include/uapi/mtd/mtd-abi.h accordingly.

This patch is analogous to the previous sync file export patch in that
it allows you to import a sync_file into a dma-buf. Unlike the previous
patch, however, this does add genuinely new functionality to dma-buf.
Without this, the only way to attach a sync_file to a dma-buf is to
submit a batch to your driver of choice which waits on the sync_file and
claims to write to the dma-buf. Even if said batch is a no-op, a submit
is typically way more overhead than just attaching a fence. A submit
may also imply extra synchronization with other work because it happens
on a hardware queue.
In the Vulkan world, this is useful for dealing with the out-fence from
vkQueuePresent. Current Linux window-systems (X11, Wayland, etc.) all
rely on dma-buf implicit sync. Since Vulkan is an explicit sync API, we
get a set of fences (VkSemaphores) in vkQueuePresent and have to stash
those as an exclusive (write) fence on the dma-buf. We handle it in
Mesa today with the above mentioned dummy submit trick. This ioctl
would allow us to set it directly without the dummy submit.
This may also open up possibilities for GPU drivers to move away from
implicit sync for their kernel driver uAPI and instead provide sync
files and rely on dma-buf import/export for communicating with other
implicit sync clients.
We make the explicit choice here to only allow setting RW fences which
translates to an exclusive fence on the dma_resv. There's no use for
read-only fences for communicating with other implicit sync userspace
and any such attempts are likely to be racy at best. When we got to
insert the RW fence, the actual fence we set as the new exclusive fence
is a combination of the sync_file provided by the user and all the other
fences on the dma_resv. This ensures that the newly added exclusive
fence will never signal before the old one would have and ensures that
we don't break any dma_resv contracts. We require userspace to specify
RW in the flags for symmetry with the export ioctl and in case we ever
want to support read fences in the future.
There is one downside here that's worth documenting: If two clients
writing to the same dma-buf using this API race with each other, their
actions on the dma-buf may happen in parallel or in an undefined order.
Both with and without this API, the pattern is the same: Collect all
the fences on dma-buf, submit work which depends on said fences, and
then set a new exclusive (write) fence on the dma-buf which depends on
said work. The difference is that, when it's all handled by the GPU
driver's submit ioctl, the three operations happen atomically under the
dma_resv lock. If two userspace submits race, one will happen before
the other. You aren't guaranteed which but you are guaranteed that
they're strictly ordered. If userspace manages the fences itself, then
these three operations happen separately and the two render operations
may happen genuinely in parallel or get interleaved. However, this is a
case of userspace racing with itself. As long as we ensure userspace
can't back the kernel into a corner, it should be fine.
v2 (Jason Ekstrand):
- Use a wrapper dma_fence_array of all fences including the new one
when importing an exclusive fence.
v3 (Jason Ekstrand):
- Lock around setting shared fences as well as exclusive
- Mark SIGNAL_SYNC_FILE as a read-write ioctl.
- Initialize ret to 0 in dma_buf_wait_sync_file
v4 (Jason Ekstrand):
- Use the new dma_resv_get_singleton helper
v5 (Jason Ekstrand):
- Rename the IOCTLs to import/export rather than wait/signal
- Drop the WRITE flag and always get/set the exclusive fence
v6 (Jason Ekstrand):
- Split import and export into separate patches
- New commit message
