These enums are passed to set/test_bit(). The set/test_bit() functions
take a bit number instead of a shifted value. Passing a shifted value
is a double shift bug like doing BIT(BIT(1)). The double shift bug
doesn't cause a problem here because we are only checking 0 and 1 but
if the value was 5 or above then it can lead to a buffer overflow.

ldimm64 instructions are 16-byte long, and so have to be handled
appropriately in check_cfg(), just like the rest of BPF verifier does.
This has implications in three places:
- when determining next instruction for non-jump instructions;
- when determining next instruction for callback address ldimm64
instructions (in visit_func_call_insn());
- when checking for unreachable instructions, where second half of
ldimm64 is expected to be unreachable;
We take this also as an opportunity to report jump into the middle of
ldimm64. And adjust few test_verifier tests accordingly.

Martin and Vadim reported a verifier failure with bpf_dynptr usage.
The issue is mentioned but Vadim workarounded the issue with source
change ([1]). The below describes what is the issue and why there
is a verification failure.
int BPF_PROG(skb_crypto_setup) {
struct bpf_dynptr algo, key;
...
bpf_dynptr_from_mem(..., ..., 0, &algo);
...
}
The bpf program is using vmlinux.h, so we have the following definition in
vmlinux.h:
struct bpf_dynptr {
long: 64;
long: 64;
};
Note that in uapi header bpf.h, we have
struct bpf_dynptr {
long: 64;
long: 64;
} __attribute__((aligned(8)));
So we lost alignment information for struct bpf_dynptr by using vmlinux.h.
Let us take a look at a simple program below:
$ cat align.c
typedef unsigned long long __u64;
struct bpf_dynptr_no_align {
__u64 :64;
__u64 :64;
};
struct bpf_dynptr_yes_align {
__u64 :64;
__u64 :64;
} __attribute__((aligned(8)));
void bar(void *, void *);
int foo() {
struct bpf_dynptr_no_align a;
struct bpf_dynptr_yes_align b;
bar(&a, &b);
return 0;
}
$ clang --target=bpf -O2 -S -emit-llvm align.c
Look at the generated IR file align.ll:
...
%a = alloca %struct.bpf_dynptr_no_align, align 1
%b = alloca %struct.bpf_dynptr_yes_align, align 8
...
The compiler dictates the alignment for struct bpf_dynptr_no_align is 1 and
the alignment for struct bpf_dynptr_yes_align is 8. So theoretically compiler
could allocate variable %a with alignment 1 although in reallity the compiler
may choose a different alignment by considering other local variables.
In [1], the verification failure happens because variable 'algo' is allocated
on the stack with alignment 4 (fp-28). But the verifer wants its alignment
to be 8.
To fix the issue, the RFC patch ([1]) tried to add '__attribute__((aligned(8)))'
to struct bpf_dynptr plus other similar structs. Andrii suggested that
we could directly modify uapi struct with named fields like struct 'bpf_iter_num':
struct bpf_iter_num {
/* opaque iterator state; having __u64 here allows to preserve correct
* alignment requirements in vmlinux.h, generated from BTF
*/
__u64 __opaque[1];
} __attribute__((aligned(8)));
Indeed, adding named fields for those affected structs in this patch can preserve
alignment when bpf program references them in vmlinux.h. With this patch,
the verification failure in [1] can also be resolved.

This refactoring patch removes the unused BPF_GRAPH_NODE_OR_ROOT
btf_field_type and moves BPF_GRAPH_{NODE,ROOT} macros into the
btf_field_type enum. Further patches in the series will use
BPF_GRAPH_NODE, so let's move this useful definition out of btf.c.

Different types of bpf dynptr have different internal data storage.
Specifically, SKB and XDP type of dynptr may have non-continuous data.
Therefore, it is not always safe to directly access dynptr->data.
Add __bpf_dynptr_data and __bpf_dynptr_data_rw to replace direct access to
dynptr->data.
Update bpf_verify_pkcs7_signature to use __bpf_dynptr_data instead of
dynptr->data.

Currently, job flow control is implemented simply by limiting the number
of jobs in flight. Therefore, a scheduler is initialized with a credit
limit that corresponds to the number of jobs which can be sent to the
hardware.
This implies that for each job, drivers need to account for the maximum
job size possible in order to not overflow the ring buffer.
However, there are drivers, such as Nouveau, where the job size has a
rather large range. For such drivers it can easily happen that job
submissions not even filling the ring by 1% can block subsequent
submissions, which, in the worst case, can lead to the ring run dry.
In order to overcome this issue, allow for tracking the actual job size
instead of the number of jobs. Therefore, add a field to track a job's
credit count, which represents the number of credits a job contributes
to the scheduler's credit limit.

A new helper is added for cgroup1 hierarchy:
- task_get_cgroup1
Acquires the associated cgroup of a task within a specific cgroup1
hierarchy. The cgroup1 hierarchy is identified by its hierarchy ID.
This helper function is added to facilitate the tracing of tasks within
a particular container or cgroup dir in BPF programs. It's important to
note that this helper is designed specifically for cgroup1 only.

At present, when we perform operations on the cgroup root_list, we must
hold the cgroup_mutex, which is a relatively heavyweight lock. In reality,
we can make operations on this list RCU-safe, eliminating the need to hold
the cgroup_mutex during traversal. Modifications to the list only occur in
the cgroup root setup and destroy paths, which should be infrequent in a
production environment. In contrast, traversal may occur frequently.
Therefore, making it RCU-safe would be beneficial.

BTRFS_EXTENT_OWNER_REF_KEY is the type of simple quotas extent owner
refs. This special inline ref goes in front of all other inline refs.
In general, inline refs have a required sorted order s.t. type never
decreases (among other requirements). This was recently reified into a
tree-checker and fsck rule, which broke simple quotas. To be fair,
though, in a sense, the new owner ref item had also violated that not
yet fully enforced requirement.
This fix brings the owner ref item into compliance with the requirement
that inline ref type never decrease.
btrfs/301 exercises this behavior and should pass again with this fix.

Referenced commit doesn't always set iifidx when offloading the flow to
hardware. Fix the following cases:
- nf_conn_act_ct_ext_fill() is called before extension is created with
nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with
unspecified iifidx when connection is offloaded after only single
original-direction packet has been processed by tc data path. Always fill
the new nf_conn_act_ct_ext instance after creating it in
nf_conn_act_ct_ext_add().
- Offloading of unidirectional UDP NEW connections is now supported, but ct
flow iifidx field is not updated when connection is promoted to
bidirectional which can result reply-direction iifidx to be zero when
refreshing the connection. Fill in the extension and update flow iifidx
before calling flow_offload_refresh().

-EOPNOTSUPP is the return value that implements a "no-op" hook, not 0.
Without this fix having only the BPF LSM enabled (with no programs
attached) can cause uninitialized variable reads in
nfsd4_encode_fattr(), because the BPF hook returns 0 without touching
the 'ctxlen' variable and the corresponding 'contextlen' variable in
nfsd4_encode_fattr() remains uninitialized, yet being treated as valid

The keyring and auth functions can be called from both the host and
the target side and are controlled by Kconfig options for each of the
combinations, but the declarations are controlled by #ifdef checks
on the shared Kconfig symbols.
This leads to link failures in combinations where one of the frontends
is built-in and the other one is a module, and the keyring code
ends up in a module that is not reachable from the builtin code:
ld: drivers/nvme/host/core.o: in function `nvme_core_exit':

Add helpers drivers can use to calculate the BW allocation overhead -
due to SSC, FEC, DSC and data alignment on symbol cycles - and the
channel coding efficiency - due to the 8b/10b, 128b/132b encoding. On
128b/132b links the FEC overhead is part of the coding efficiency, so
not accounted for in the BW allocation overhead.
The drivers can use these functions to calculate a ratio, controlling
the stream symbol insertion rate of the source device in each SST TU
or MST MTP frame. Drivers can calculate this
m/n = (pixel_data_rate * drm_dp_bw_overhead()) /
(link_data_rate * drm_dp_bw_channel_coding_efficiency())
ratio for a given link and pixel stream and with that the
slots_per_mtp = CEIL(64 * m / n)
allocated slots per MTP for the stream in a link frame and with
that the
pbn = slots_per_mtp * drm_mst_get_pbn_divider()
allocated PBNs for the stream on the MST link path.
Take drm_dp_bw_overhead() into use in drm_dp_calc_pbn_mode(), for
drivers calculating the PBN value directly.
v2:
- Add dockbook description to drm_dp_bw_channel_coding_efficiency().
(LKP).
- Clarify the way m/n ratio is calculated in the commit log.
v3:
- Fix compile breakage for !CONFIG_BACKLIGHT_CLASS_DEVICE. (LKP)
- Account for FEC_PM overhead (+ 0.0015625 %), add comment
with the formula to calculate the total FEC overhead. (Ville)
v4:
- Rename DRM_DP_OVERHEAD_SSC to DRM_DP_OVERHEAD_SSC_REF_CLK. (Ville)
v5:
- Clarify in the commit log what MTP means.
- Simplify the commit log's formula to calculate PBN.

The current code does '(bpp << 4) / 16' in the MST PBN
calculation, but that is just the same as 'bpp' so the
DSC codepath achieves absolutely nothing. Fix it up so that
the fractional part of the bpp value is actually used instead
of truncated away. 64*1006 has enough zero lsbs that we can
just shift that down in the dividend and thus still manage
to stick to a 32bit divisor.
And while touching this, let's just make the whole thing more
straightforward by making the passed in bpp value .4 binary
fixed point always, instead of having to pass in different
things based on whether DSC is enabled or not.

- Fix DSC kunit test cases.

Pull vfs fanotify fsid updates from Christian Brauner:
"This work is part of the plan to enable fanotify to serve as a drop-in
replacement for inotify. While inotify is availabe on all filesystems,
fanotify currently isn't.
In order to support fanotify on all filesystems two things are needed:
(1) all filesystems need to support AT_HANDLE_FID
(2) all filesystems need to report a non-zero f_fsid
This contains (1) and allows filesystems to encode non-decodable file
handlers for fanotify without implementing any exportfs operations by
encoding a file id of type FILEID_INO64_GEN from i_ino and
i_generation.
Filesystems that want to opt out of encoding non-decodable file ids
for fanotify that don't support NFS export can do so by providing an
empty export_operations struct.
This also partially addresses (2) by generating f_fsid for simple
filesystems as well as freevxfs. Remaining filesystems will be dealt
with by separate patches.
Finally, this contains the patch from the current exportfs maintainers
which moves exportfs under vfs with Chuck, Jeff, and Amir as
maintainers and vfs.git as tree"

This reverts commit a08799cf17c22375752abfad3b4a2b34b3acb287.
The recently added Realtek PHY drivers depend on the new port status
notification mechanism which was built on the deprecated USB PHY
implementation and devicetree binding.
Specifically, using these PHYs would require describing the very same
PHY using both the generic "phy" property and the deprecated "usb-phy"
property which is clearly wrong.
We should not be building new functionality on top of the legacy USB PHY
implementation even if it is currently stuck in some kind of
transitional limbo.
Revert the new notification interface which is broken by design.
Fixes: a08799cf17c2 ("usb: phy: add usb phy notify port status API")

This patch moves dma_addressing_limited() out of line, serving as a
preliminary step to prevent the introduction of a new publicly accessible
low-level helper when validating whether all system RAM is mapped within
the DMA mapping range.
