====================
check bpf_dummy_struct_ops program params for test runs
When doing BPF_PROG_TEST_RUN for bpf_dummy_struct_ops programs,
execution should be rejected when NULL is passed for non-nullable
params, because for such params verifier assumes that such params are
never NULL and thus might optimize out NULL checks.
This problem was reported by Jose E. Marchesi in off-list discussion.
The code generated by GCC for dummy_st_ops_success/test_1() function
differs from LLVM variant in a way that allows verifier to remove the
NULL check. The test dummy_st_ops/dummy_init_ret_value actually sets
the 'state' parameter to NULL, thus GCC-generated version of the test
triggers NULL pointer dereference when BPF program is executed.
This patch-set addresses the issue in the following steps:
- patch #1 marks bpf_dummy_struct_ops.test_1 parameter as nullable,
for verifier to have correct assumptions about test_1() programs;
- patch #2 modifies dummy_st_ops/dummy_init_ret_value to trigger NULL
dereference with both GCC and LLVM (if patch #1 is not applied);
- patch #3 adjusts a few dummy_st_ops test cases to avoid passing NULL
for 'state' parameter of test_2() and test_sleepable() functions,
as parameters of these functions are not marked as nullable;
- patch #4 adjusts bpf_dummy_struct_ops to reject test execution of
programs if NULL is passed for non-nullable parameter;
- patch #5 adds a test to verify logic from patch #4.

dummy_st_ops.test_2 and dummy_st_ops.test_sleepable do not have their
'state' parameter marked as nullable. Update dummy_st_ops.c to avoid
passing NULL for such parameters, as the next patch would allow kernel
to enforce this restriction.

As reported by Jose E. Marchesi in off-list discussion, GCC and LLVM
generate slightly different code for dummy_st_ops_success/test_1():
SEC("struct_ops/test_1")
int BPF_PROG(test_1, struct bpf_dummy_ops_state *state)
{
int ret;
if (!state)
return 0xf2f3f4f5;
ret = state->val;
state->val = 0x5a;
return ret;
}
GCC-generated LLVM-generated
---------------------------- ---------------------------
0: r1 = *(u64 *)(r1 + 0x0) 0: w0 = -0xd0c0b0b
1: if r1 == 0x0 goto 5f 1: r1 = *(u64 *)(r1 + 0x0)
2: r0 = *(s32 *)(r1 + 0x0) 2: if r1 == 0x0 goto 6f
3: *(u32 *)(r1 + 0x0) = 0x5a 3: r0 = *(u32 *)(r1 + 0x0)
4: exit 4: w2 = 0x5a
5: r0 = -0xd0c0b0b 5: *(u32 *)(r1 + 0x0) = r2
6: exit 6: exit
If the 'state' argument is not marked as nullable in
net/bpf/bpf_dummy_struct_ops.c, the verifier would assume that
'r1 == 0x0' is never true:
- for the GCC version, this means that instructions #5-6 would be
marked as dead and removed;
- for the LLVM version, all instructions would be marked as live.
The test dummy_st_ops/dummy_init_ret_value actually sets the 'state'
parameter to NULL.
Therefore, when the 'state' argument is not marked as nullable,
the GCC-generated version of the code would trigger a NULL pointer
dereference at instruction #3.
This patch updates the test_1() test case to always follow a shape
similar to the GCC-generated version above, in order to verify whether
the 'state' nullability is marked correctly.

Test case dummy_st_ops/dummy_init_ret_value passes NULL as the first
parameter of the test_1() function. Mark this parameter as nullable to
make verifier aware of such possibility.
Otherwise, NULL check in the test_1() code:
SEC("struct_ops/test_1")
int BPF_PROG(test_1, struct bpf_dummy_ops_state *state)
{
if (!state)
return ...;
... access state ...
}
Might be removed by verifier, thus triggering NULL pointer dereference
under certain conditions.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

papr_scm and ndtest share common PDSM payload structs like
nd_papr_pdsm_health. Presently these structs are duplicated across
papr_pdsm.h and ndtest.h header files. Since 'ndtest' is essentially
arch independent and can run on platforms other than PPC64, a way
needs to be deviced to avoid redundancy and duplication of PDSM
structs in future.
So the patch proposes moving the PDSM header from arch/powerpc/include-
-/uapi/ to the generic include/uapi/linux directory. Also, there
are some #defines common between papr_scm and ndtest which are not
exported to the user space. So, move them to a header file which
can be shared across ndtest and papr_scm via newly introduced
include/linux/papr_scm.h.

While testing TCP performance with latest trees,
I saw suspect SOCKET_BACKLOG drops.
tcp_add_backlog() computes its limit with :
limit = (u32)READ_ONCE(sk->sk_rcvbuf) +
(u32)(READ_ONCE(sk->sk_sndbuf) >> 1);
limit += 64 * 1024;
This does not take into account that sk->sk_backlog.len
is reset only at the very end of __release_sock().
Both sk->sk_backlog.len and sk->sk_rmem_alloc could reach
sk_rcvbuf in normal conditions.
We should double sk->sk_rcvbuf contribution in the formula
to absorb bubbles in the backlog, which happen more often
for very fast flows.
This change maintains decent protection against abuses.

Pull ACPI fixes from Rafael Wysocki:
"These fix three recent regressions, one introduced while enabling a
new platform firmware feature for power management, and two introduced
by a recent CPPC library update.
Specifics:
- Allow two overlapping Low-Power S0 Idle _DSM function sets to be
used at the same time (Rafael Wysocki)
- Fix bit offset computation in MASK_VAL() macro used for applying a
bitmask to a new CPPC register value (Jarred White)
- Fix access width field usage for PCC registers in CPPC (Vanshidhar
Konda)"

Nothing major, regression fixes are mostly in drivers, two more
of those are flowing towards us thru various trees. I wish some of
the changes went into -rc5, we'll try to keep an eye on frequency
of PRs from sub-trees.
Also disproportional number of fixes for bugs added in v6.4,
strange coincidence.
Current release - regressions:
- igc: fix LED-related deadlock on driver unbind
- wifi: mac80211: small fixes to recent clean up of the connection
process
- Revert "wifi: iwlwifi: bump FW API to 90 for BZ/SC devices",

- Bluetooth:
- set power_ctrl_enabled on NULL returned by gpiod_get_optional()
- qca: fix invalid device address check, again

__this_cpu_{add|sub}* are not IRQ-safe

RZ/{G2L, V2L, G3S}-based CPG versions have support for saving extra
power when clocks are disabled by activating module standby. This is
done through MSTOP-specific registers that are part of CPG. Each
individual module has one or more bits associated with one MSTOP
register (see table "Registers for Module Standby Mode" from HW
manuals). Hardware manual associates modules' clocks with one or more
MSTOP bits. There are 3 mappings available (identified by researching
RZ/G2L, RZ/G3S, RZ/V2L HW manuals):
case 1: N clocks mapped to N MSTOP bits (with N={0, ..., X})
case 2: N clocks mapped to 1 MSTOP bit (with N={0, ..., X})
case 3: N clocks mapped to M MSTOP bits (with N={0, ..., X}, M={0, ..., Y})
Case 3 has been currently identified on RZ/V2L for the VCPL4 module.
To cover all three cases, the individual platform drivers will provide
the clock driver with MSTOP register offsets and associated bits in this
register as a bitmask, and the clock driver will apply this bitmask to
the proper MSTOP register.
The MSTOP support was implemented through power domains.
Platform-specific clock drivers will register an array of type struct
rzg2l_cpg_pm_domain_init_data, which will be used to instantiate
properly the power domains.

The driver will be modified (in the next commits) to be able to specify
individual power domain IDs for each IP. The driver will still
support #power-domain-cells = <0>, thus, previous users are not
affected.
The #power-domain-cells = <1> has been instantiated only for RZ/G3S at
the moment, as individual platform clock drivers need to be adapted for
this to be supported on the rest of the SoCs.
Also, the description for #power-domain-cells is updated with links to
per-SoC power domain IDs.

replacement with PCI_IRQ_INTX, rename macros and functions referencing
"legacy irq" to instead use the term "intx irq".
