ColdFire is a big-endian cpu with a big-endian dspi hw module,
so, it uses native access, but memcpy breaks the endianness.
So, if i understand properly, by native copy we would mean
be(cpu)->be(dspi) or le(cpu)->le(dspi) accesses, so my fix
shouldn't break anything, but i couldn't test it on LS family,
so every test is really appreciated.

After previous fix for zero extension test_verifier tests #65 and #66 now
fail. Before the fix we can see the alu32 mov op at insn 10
10: R0_w=map_value(id=0,off=0,ks=8,vs=8,imm=0)
R1_w=invP(id=0,
smin_value=4294967168,smax_value=4294967423,
umin_value=4294967168,umax_value=4294967423,
var_off=(0x0; 0x1ffffffff),
s32_min_value=-2147483648,s32_max_value=2147483647,
u32_min_value=0,u32_max_value=-1)
R10=fp0 fp-8_w=mmmmmmmm
10: (bc) w1 = w1
11: R0_w=map_value(id=0,off=0,ks=8,vs=8,imm=0)
R1_w=invP(id=0,
smin_value=0,smax_value=2147483647,
umin_value=0,umax_value=4294967295,
var_off=(0x0; 0xffffffff),
s32_min_value=-2147483648,s32_max_value=2147483647,
u32_min_value=0,u32_max_value=-1)
R10=fp0 fp-8_w=mmmmmmmm
After the fix at insn 10 because we have 's32_min_value < 0' the following
step 11 now has 'smax_value=U32_MAX' where before we pulled the s32_max_value
bound into the smax_value as seen above in 11 with smax_value=2147483647.
10: R0_w=map_value(id=0,off=0,ks=8,vs=8,imm=0)
R1_w=inv(id=0,
smin_value=4294967168,smax_value=4294967423,
umin_value=4294967168,umax_value=4294967423,
var_off=(0x0; 0x1ffffffff),
s32_min_value=-2147483648, s32_max_value=2147483647,
u32_min_value=0,u32_max_value=-1)
R10=fp0 fp-8_w=mmmmmmmm
10: (bc) w1 = w1
11: R0_w=map_value(id=0,off=0,ks=8,vs=8,imm=0)
R1_w=inv(id=0,
smin_value=0,smax_value=4294967295,
umin_value=0,umax_value=4294967295,
var_off=(0x0; 0xffffffff),
s32_min_value=-2147483648, s32_max_value=2147483647,
u32_min_value=0, u32_max_value=-1)
R10=fp0 fp-8_w=mmmmmmmm
The fall out of this is by the time we get to the failing instruction at
step 14 where previously we had the following:
14: R0_w=map_value(id=0,off=0,ks=8,vs=8,imm=0)
R1_w=inv(id=0,
smin_value=72057594021150720,smax_value=72057594029539328,
umin_value=72057594021150720,umax_value=72057594029539328,
var_off=(0xffffffff000000; 0xffffff),
s32_min_value=-16777216,s32_max_value=-1,
u32_min_value=-16777216,u32_max_value=-1)
R10=fp0 fp-8_w=mmmmmmmm
14: (0f) r0 += r1
We now have,
14: R0_w=map_value(id=0,off=0,ks=8,vs=8,imm=0)
R1_w=inv(id=0,
smin_value=0,smax_value=72057594037927935,
umin_value=0,umax_value=72057594037927935,
var_off=(0x0; 0xffffffffffffff),
s32_min_value=-2147483648,s32_max_value=2147483647,
u32_min_value=0,u32_max_value=-1)
R10=fp0 fp-8_w=mmmmmmmm
14: (0f) r0 += r1
In the original step 14 'smin_value=72057594021150720' this trips the logic
in the verifier function check_reg_sane_offset(),
if (smin >= BPF_MAX_VAR_OFF || smin <= -BPF_MAX_VAR_OFF) {
verbose(env, "value %lld makes %s pointer be out of bounds\n",
smin, reg_type_str[type]);
return false;
}
Specifically, the 'smin <= -BPF_MAX_VAR_OFF' check. But with the fix
at step 14 we have bounds 'smin_value=0' so the above check is not tripped
because BPF_MAX_VAR_OFF=1<<29.
We have a smin_value=0 here because at step 10 the smaller smin_value=0 means
the subtractions at steps 11 and 12 bring the smin_value negative.
11: (17) r1 -= 2147483584
12: (17) r1 -= 2147483584
13: (77) r1 >>= 8
Then the shift clears the top bit and smin_value is set to 0. Note we still
have the smax_value in the fixed code so any reads will fail. An alternative
would be to have reg_sane_check() do both smin and smax value tests.
To fix the test we can omit the 'r1 >>=8' at line 13. This will change the
err string, but keeps the intention of the test as suggseted by the title,
"check after truncation of boundary-crossing range". If the verifier logic
changes a different value is likely to be thrown in the error or the error
will no longer be thrown forcing this test to be examined. With this change
we see the new state at step 13.
13: R0_w=map_value(id=0,off=0,ks=8,vs=8,imm=0)
R1_w=invP(id=0,
smin_value=-4294967168,smax_value=127,
umin_value=0,umax_value=18446744073709551615,
s32_min_value=-2147483648,s32_max_value=2147483647,
u32_min_value=0,u32_max_value=-1)
R10=fp0 fp-8_w=mmmmmmmm
Giving the expected out of bounds error, "value -4294967168 makes map_value
pointer be out of bounds" However, for unpriv case we see a different error
now because of the mixed signed bounds pointer arithmatic. This seems OK so
I've only added the unpriv_errstr for this. Another optino may have been to
do addition on r1 instead of subtraction but I favor the approach above
slightly.

With the latest trunk llvm (llvm 11), I hit a verifier issue for
test_prog subtest test_verif_scale1.
The following simplified example illustrate the issue:
w9 = 0 /* R9_w=inv0 */
r8 = *(u32 *)(r1 + 80) /* __sk_buff->data_end */
r7 = *(u32 *)(r1 + 76) /* __sk_buff->data */
......
w2 = w9 /* R2_w=inv0 */
r6 = r7 /* R6_w=pkt(id=0,off=0,r=0,imm=0) */
r6 += r2 /* R6_w=inv(id=0) */
r3 = r6 /* R3_w=inv(id=0) */
r3 += 14 /* R3_w=inv(id=0) */
if r3 > r8 goto end
r5 = *(u32 *)(r6 + 0) /* R6_w=inv(id=0) */
<== error here: R6 invalid mem access 'inv'
...
end:
In real test_verif_scale1 code, "w9 = 0" and "w2 = w9" are in
different basic blocks.
In the above, after "r6 += r2", r6 becomes a scalar, which eventually
caused the memory access error. The correct register state should be
a pkt pointer.
The inprecise register state starts at "w2 = w9".
The 32bit register w9 is 0, in __reg_assign_32_into_64(),
the 64bit reg->smax_value is assigned to be U32_MAX.
The 64bit reg->smin_value is 0 and the 64bit register
itself remains constant based on reg->var_off.
In adjust_ptr_min_max_vals(), the verifier checks for a known constant,
smin_val must be equal to smax_val. Since they are not equal,
the verifier decides r6 is a unknown scalar, which caused later failure.
The llvm10 does not have this issue as it generates different code:
w9 = 0 /* R9_w=inv0 */
r8 = *(u32 *)(r1 + 80) /* __sk_buff->data_end */
r7 = *(u32 *)(r1 + 76) /* __sk_buff->data */
......
r6 = r7 /* R6_w=pkt(id=0,off=0,r=0,imm=0) */
r6 += r9 /* R6_w=pkt(id=0,off=0,r=0,imm=0) */
r3 = r6 /* R3_w=pkt(id=0,off=0,r=0,imm=0) */
r3 += 14 /* R3_w=pkt(id=0,off=14,r=0,imm=0) */
if r3 > r8 goto end
...
To fix the above issue, we can include zero in the test condition for
assigning the s32_max_value and s32_min_value to their 64-bit equivalents
smax_value and smin_value.
Further, fix the condition to avoid doing zero extension bounds checks
when s32_min_value <= 0. This could allow for the case where bounds
32-bit bounds (-1,1) get incorrectly translated to (0,1) 64-bit bounds.
When in-fact the -1 min value needs to force U32_MAX bound.

now that can be done conveniently - all non-trivial cases have
_HAVE_ARCH_COPY_AND_CSUM_FROM_USER defined, so the fallback in
net/checksum.h is used only for dummy (copy_from_user, then

We already have stac/clac pair around the calls of csum_partial_copy_generic().
Stretch that area back, so that it covers the preceding loop (and convert
the loop body from __{get,put}_user() to unsafe_{get,put}_user()).
That brings the beginning of the areas to the earlier access_ok(),
which allows to convert them into user_access_{begin,end}() ones.

without also manually disabling MLX5_TC_CT.

Add a call to mlx5e_reset_rx/tx_moderation() when enabling/disabling
adaptive moderation, in order to select the proper default values.
In order to do so, we separate the logic of selecting the moderation values
and setting moderion mode (CQE/EQE based).

Change type of active_fec to u32 to match the type expected by
mlx5e_get_fec_mode. Copy active_fec and configured_fec values to
unsigned long before preforming bitwise manipulations.
Take the same approach when configuring FEC over 50G link modes: copy
the policy into an unsigned long and only than preform bitwise
operations.

On tunnel decap rule insertion, the indirect mechanism will attempt to
offload the rule on all uplink representors which will trigger the
"devices are not on same switch HW, can't offload forwarding" message
for the uplink which isn't on the same switch HW as the VF representor.
The above flow is valid and shouldn't cause warning message,
fix by removing the warning and only report this flow using extack.

Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces two DW SPI legacy
bare text bindings with YAML file. As before the bindings file states
that the corresponding dts node is supposed to be compatible either
with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel
vendors-specific controllers, to have registers, interrupts and clocks
properties. Though in case of Microsemi version of the controller
there must be two registers resources specified. Properties like
clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device
sub-nodes are optional.

It's better to understand what bits are set for DMA and for IRQ handling
in mid_spi_dma_setup() if they are grouped accordingly. Thus,
refactor mid_spi_dma_setup() to separate DMA and IRQ configuration.

The 2afccbd283ae ("spi: dw: Discard static DW DMA slave structures")
did a clean up of global variables, which is fine, but messed up with
the carefully provided information in the custom DMA slave structures.
There reader can find an assignment of the DMA request lines in use.
Partially revert the above mentioned commit to restore readability
and maintainability of the code.
