The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for samples/bpf/ibumad_kern.c follows this syntax, but
the content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warnings from kernel-doc:

LLVM patch https://reviews.llvm.org/D102712
narrowed the scope of existing R_BPF_64_64
and R_BPF_64_32 relocations, and added three
new relocations, R_BPF_64_ABS64, R_BPF_64_ABS32
and R_BPF_64_NODYLD32. The main motivation is
to make relocations linker friendly.
This change, unfortunately, breaks libbpf build,
and we will see errors like below:
libbpf: ELF relo #0 in section #6 has unexpected type 2 in
/home/yhs/work/bpf-next/tools/testing/selftests/bpf/bpf_tcp_nogpl.o
Error: failed to link
'/home/yhs/work/bpf-next/tools/testing/selftests/bpf/bpf_tcp_nogpl.o':
Unknown error -22 (-22)
The new relocation R_BPF_64_ABS64 is generated
and libbpf linker sanity check doesn't understand it.
Relocation section '.rel.struct_ops' at offset 0x1410 contains 1 entries:
Offset Info Type Symbol's Value Symbol's Name
0000000000000018 0000000700000002 R_BPF_64_ABS64 0000000000000000 nogpltcp_init
Look at the selftests/bpf/bpf_tcp_nogpl.c,
void BPF_STRUCT_OPS(nogpltcp_init, struct sock *sk)
{
}
SEC(".struct_ops")
struct tcp_congestion_ops bpf_nogpltcp = {
.init = (void *)nogpltcp_init,
.name = "bpf_nogpltcp",
};
The new llvm relocation scheme categorizes 'nogpltcp_init' reference
as R_BPF_64_ABS64 instead of R_BPF_64_64 which is used to specify
ld_imm64 relocation in the new scheme.
Let us fix the linker sanity checking by including
R_BPF_64_ABS64 and R_BPF_64_ABS32. There is no need to
check R_BPF_64_NODYLD32 which is used for .BTF and .BTF.ext.

====================
This patch series extends the existing bpf_map_lookup_and_delete_elem()
functionality with 4 more map types:
- BPF_MAP_TYPE_HASH,
- BPF_MAP_TYPE_PERCPU_HASH,
- BPF_MAP_TYPE_LRU_HASH and
- BPF_MAP_TYPE_LRU_PERCPU_HASH.
Patch 1 adds most of its functionality and logic as well as
documentation.
As it was previously limited to only stacks and queues which do not
support the BPF_F_LOCK flag, patch 2 enables its usage by adding a new
libbpf API bpf_map_lookup_and_delete_elem_flags() based on the existing
bpf_map_lookup_elem_flags().
Patch 3 adds selftests for lookup_and_delete_elem().
Changes in patch 1:
v7: Minor formating nits, add Acked-by.
v6: Remove unneeded flag check, minor code/format fixes.
v5: Split patch to 3 patches. Extend BPF_MAP_LOOKUP_AND_DELETE_ELEM
documentation with this changes.
v4: Fix the return value for unsupported map types.
v3: Add bpf_map_lookup_and_delete_elem_flags() and enable BPF_F_LOCK
flag, change CHECKs to ASSERT_OKs, initialize variables to 0.
v2: Add functionality for LRU/per-CPU, add test_progs tests.
Changes in patch 2:
v7: No change.
v6: Add Acked-by.
v5: Move to the newest libbpf version (0.4.0).
Changes in patch 3:
v7: Remove ASSERT_GE macro which is already added in some other commit,
change ASSERT_OK to ASSERT_OK_PTR, add Acked-by.
v6: Remove PERCPU macros, add ASSERT_GE macro to test_progs.h, remove

Ethtool statistics counters cleanup for SJA1105 DSA driver
This series removes some reported data from ethtool -S which were not
counters at all, and reorganizes the code such that counters can be read
individually and not just all at once.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The current internal sja1105 driver API is optimized for retrieving many
statistics counters at once. But the switch does not do atomic snapshotting
for them anyway.
In case we start reporting the hardware port counters through
ndo_get_stats64 as well, not just ethtool, it would be good to be able
to read individual port counters and not all of them.
Additionally, since Arnd Bergmann's commit ae1804de93 ("dsa: sja1105:
dynamically allocate stats structure"), sja1105_get_ethtool_stats
allocates memory dynamically, since struct sja1105_port_status was
deemed to consume too much stack memory. That is not ideal.
The large structure is only needed because of the burst read.
If we read statistics one by one, we can consume less memory, and
we can avoid dynamic allocation.
Additionally, latency-sensitive interfaces such as PTP operations (for
phc2sys) might suffer if the SPI mutex is being held for too long, which
happens in the case of SPI burst reads. By reading counters one by one,
we give a chance for higher priority processes to preempt and take the
SPI bus mutex for accessing the PTP clock.

Adapt the sja1105 DSA driver to the SPI controller's transfer limits
This series changes the SPI transfer procedure in sja1105 to take into
consideration the buffer size limitations that the SPI controller driver
might have.
Changes in v2:
Remove the driver's use of cs_change and send multiple, smaller SPI
messages instead of a single large one.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The static config of the sja1105 switch is a long stream of bytes which
is programmed to the hardware in chunks (portions with the chip select
continuously asserted) of max 256 bytes each. Each chunk is a
spi_message composed of 2 spi_transfers: the buffer with the data and a
preceding buffer with the SPI access header.
Only that certain SPI controllers, such as the spi-sc18is602 I2C-to-SPI
bridge, cannot keep the chip select asserted for that long.
The spi_max_transfer_size() and spi_max_message_size() functions are how
the controller can impose its hardware limitations upon the SPI
peripheral driver.
For the sja1105 driver to work with these controllers, both buffers must
be smaller than the transfer limit, and their sum must be smaller than
the message limit.
Regression-tested on a switch connected to a controller with no
limitations (spi-fsl-dspi) as well as with one with caps for both
max_transfer_size and max_message_size (spi-sc18is602).
Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
The sja1105 driver has been described by Mark Brown as "not using the
[ SPI ] API at all idiomatically" due to the use of cs_change:
https://patchwork.kernel.org/project/netdevbpf/patch/20210520135031.2969183-1-olteanv@gmail.com/
According to include/linux/spi/spi.h, the chip select is supposed to be
asserted for the entire length of a SPI message, as long as cs_change is
false for all member transfers. The cs_change flag changes the following:
(i) When a non-final SPI transfer has cs_change = true, the chip select
should temporarily deassert and then reassert starting with the next
transfer.
(ii) When a final SPI transfer has cs_change = true, the chip select
should remain asserted until the following SPI message.
The sja1105 driver only uses cs_change for its first property, to form a
single SPI message whose layout can be seen below:
this is an entire, single spi_message
_______________________________________________________________________________________________
/ \
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
| hdr_xfer[0] | chunk_xfer[0] | hdr_xfer[1] | chunk_xfer[1] | | hdr_xfer[n] | chunk_xfer[n] |
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
cs_change false true false true false false
____________________________ _____________________________ _____________________________
CS line __/ \/ \ ... / \__
The fact of the matter is that spi_max_message_size() has an ambiguous
meaning if any non-final transfer has cs_change = true.
If the SPI master has a limitation in that it cannot keep the chip
select asserted for more than, say, 200 bytes (like the spi-sc18is602),
the normal thing for it to do is to implement .max_transfer_size and
.max_message_size, and limit both to 200: in the "worst case" where
cs_change is always false, then the controller can, indeed, not send
messages larger than 200 bytes.
But the fact that the SPI controller's max_message_size does not
necessarily mean that we cannot send messages larger than that.
Notably, if the SPI master special-cases the transfers with cs_change
and treats every chip select toggling as an entirely new transaction,
then a SPI message can easily exceed that limit. So there is a
temptation to ignore the controller's reported max_message_size when
using cs_change = true in non-final transfers.
But that can lead to false conclusions. As Mark points out, the SPI
controller might have a different kind of limitation with the max
message size, that has nothing at all to do with how long it can keep
the chip select asserted.
For example, that might be the case if the device is able to offload the
chip select changes to the hardware as part of the data stream, and it
packs the entire stream of commands+data (corresponding to a SPI
message) into a single DMA transfer that is itself limited in size.
So the only thing we can do is avoid ambiguity by not using cs_change at
all. Instead of sending a single spi_message, we now send multiple SPI
messages as follows:
spi_message 0 spi_message 1 spi_message n
____________________________ ___________________________ _____________________________
/ \ / \ / \
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
| hdr_xfer[0] | chunk_xfer[0] | hdr_xfer[1] | chunk_xfer[1] | | hdr_xfer[n] | chunk_xfer[n] |
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
cs_change false true false true false false
____________________________ _____________________________ _____________________________
CS line __/ \/ \ ... / \__
which is clearer because the max_message_size limit is now easier to
enforce. What is transmitted on the wire stays, of course, the same.
Additionally, because we send no more than 2 transfers at a time, we now
avoid dynamic memory allocation too, which might be seen as an
improvement by some.
