* [PATCH v4] dts: report dut/NIC info during DTS run
From: Koushik Bhargav Nimoji @ 2026-06-24 21:33 UTC (permalink / raw)
To: luca.vizzarro, patrickrobb1997
Cc: dev, abailey, ahassick, lylavoie, Koushik Bhargav Nimoji
In-Reply-To: <20260602163647.101815-1-knimoji@iol.unh.edu>
This patch gathers NIC info during a DTS run and writes it to an output
json file. This allows the json file to be used when reporting results
on the DTS results dashboard.
Signed-off-by: Koushik Bhargav Nimoji <knimoji@iol.unh.edu>

v2:
*Resolved merge conflicts
v3:
*Fixed an issue with retrieving
the NIC's hardware version
v4:
*Moved nic info gathering step before the nics get
binded to their respective drivers
*Condensed some areas of code in order to make them
more readable
*Removed redundant None checks and added some where
required
*Fixed LshwOutput class to better reflect the lshw
command output

* [PATCH v5] pcapng: add user-supplied timestamp support
From: Dawid Wesierski @ 2026-06-24 21:57 UTC (permalink / raw)
To: dev; +Cc: dawid.wesierski, marek.kasiewicz, thomas, stephen, mb
In-Reply-To: <20260623141302.486601-1-dawid.wesierski@intel.com>
Introduce rte_pcapng_copy_ts() alongside the existing rte_pcapng_copy()
so that callers with a hardware PTP or pre-captured timestamp can inject
an exact epoch-ns value directly into the packet record.
Timestamp handling in rte_pcapng_copy_ts():
- ts != 0: caller-supplied nanoseconds since the Unix epoch, stored as-is.
- ts == 0: TSC captured at copy time with bit 63 set as a sentinel.
rte_pcapng_write_packets() detects the sentinel and converts the TSC to
epoch ns using the file's calibrated clock. The TSC will not reach
bit 63 for centuries, and epoch-ns values stay below bit 63 until 2554,
so the bit is safe to use as a disambiguation flag.
rte_pcapng_copy() is retained as a real exported function (not an inline
wrapper) so the stable ABI symbol is preserved. It simply calls
rte_pcapng_copy_ts(..., 0) to capture the current TSC.
rte_pcapng_tsc_to_ns() is added as a new experimental helper (addressing
review requests from Stephen Hemminger and Morten Brørup). It exposes the
same calibrated, drift-compensated, divide-free TSC-to-epoch-ns conversion
used internally by rte_pcapng_write_packets(), allowing callers to convert
a TSC captured at packet arrival time before passing it to
rte_pcapng_copy_ts().

Hi Stephen, Morten,
Thank you for the feedback on the previous versions,
In this version i added unit Tests test case in app/test/test_pcapng.c to
verify the TSC-to-NS conversion and the custom timestamp injection.
Regards,
Dawid Węsierski

file.close() is redundant and can be removed.
More importantly, the info is gathered after the dut nics have been bound
to the dpdk driver. This is an issue if a driver is bound to vfio-pci since
it has limited visibility from the commands used to gather info. I tested
this with broadcom cards which showed various info fields that were empty
or None. This is resolved by moving this snippet before the DUT ports are
bound. Keep in mind to test your patches against multiple NICs,
preferably with different drivers.

There is a redundant check on setting the variable and then verifying.
Since you are throwing an exception if there is no valid value, you could
do a check once and throw an error and then set the variable after with no
further checks required. This makes it more readable in my opinion but let
me know if you disagree, for example...
if command.code != 0 or command.stdout == '':
raise ConfigurationError()
bus_type = command.stdout
+ bus_info = f"{bus_type}@{pci_addr}"

this code can be condensed as well, redundant check but logic is good.
If the intention is to report unknown in this case, it should be mentioned
in this log message.
Also I'm not sure if this has a logger level error if everything runs fine
in this case.
Maybe info or warning level is sufficient.

* [PATCH v5 9/9] test/bpf: check that bpf_convert can be JIT'd
From: Stephen Hemminger @ 2026-06-24 17:55 UTC (permalink / raw)
To: dev; +Cc: Stephen Hemminger, Marat Khalili, Konstantin Ananyev
In-Reply-To: <20260624175815.673064-1-stephen@networkplumber.org>
Run each converted filter through both the interpreter and the JIT and
check they agree, catching JIT miscompiles.
test_bpf_filter and test_bpf_match did nearly the same thing: compile,
load and run a filter against the dummy packet. Combine them into
test_bpf_match, which now builds the packet itself and returns whether
the filter matched. Callers run it for both load methods.
The dummy packet is a UDP packet to a fixed destination MAC, source
and destination ports, so the filter results are deterministic. None
of the sample filters should match it, so assert that; a convert or
JIT bug that flips a result is then caught. The destination MAC and
source port are chosen so the negative ethernet and port filters do
not match, and "port not 53 and not arp" is dropped as it matches
any non-ARP packet that lacks port 53.
Reduce log output to make it easier to match which expression might be
causing issues.

* [PATCH v5 8/9] test/bpf: check that JIT was generated
From: Stephen Hemminger @ 2026-06-24 17:55 UTC (permalink / raw)
To: dev; +Cc: Stephen Hemminger, Marat Khalili, Konstantin Ananyev
In-Reply-To: <20260624175815.673064-1-stephen@networkplumber.org>
Avoid silently ignoring JIT failures. The test cases should
all succeed JIT compilation; if not it is a bug in the JIT
implementation and should be reported.
Introduce a configuration setting RTE_BPF_JIT_SUPPORTED
which is cleaner than using an ARCH specific #ifdef.

* [PATCH v5 7/9] bpf/arm64: add BPF_ABS/BPF_IND packet load support
From: Stephen Hemminger @ 2026-06-24 17:55 UTC (permalink / raw)
To: dev
Cc: Stephen Hemminger, Wathsala Vithanage, Konstantin Ananyev,
Marat Khalili
In-Reply-To: <20260624175815.673064-1-stephen@networkplumber.org>
The arm64 JIT rejected BPF_LD | BPF_ABS and BPF_LD | BPF_IND with
"invalid opcode", so cBPF programs converted by rte_bpf_convert() could
not be JITed. Add these opcodes, mirroring the x86 JIT: a fast path for
data held in the first mbuf segment, and a __rte_pktmbuf_read() slow
path for everything else.
The forward branches over the call cannot use fixed distances:
emit_call() materializes the helper address with a variable number of
mov/movk instructions, so the block sizes are not known up front. Size
the three blocks (fast path, slow path, common tail) in a dry run, then
emit for real with the branches resolved from the measured offsets.
Programs using these opcodes use the call register layout, since the
slow path makes a function call.

* [PATCH v5 6/9] bpf/arm64: fix offset type to allow a negative jump
From: Stephen Hemminger @ 2026-06-24 17:55 UTC (permalink / raw)
To: dev
Cc: Christophe Fontaine, stable, Stephen Hemminger, Marat Khalili,
Wathsala Vithanage, Konstantin Ananyev, Jerin Jacob
In-Reply-To: <20260624175815.673064-1-stephen@networkplumber.org>
From: Christophe Fontaine <cfontain@redhat.com>
The DPDK BPF JIT standalone test test_ld_mbuf1 fails on arm64.
It does:
r6 = r1 // mbuf
r0 = *(u8 *)pkt[0] // BPF_ABS
if ((r0 & 0xf0) == 0x40)
goto parse
r0 = 0
exit // epilogue E0
parse:
r0 = *(u8 *)pkt[r0 + 3] // BPF_IND
...
exit
emit_return_zero_if_src_zero() returns 0 by branching to a function
epilogue. The target may be a previous epilogue so branch
might be backwards; therefore the offset needs to be negative.
The offset was stored in a uint16_t, so a negative value wrapped to a
large positive number; emit_b() then branched past the end of the
program and faulted at run time.

The interpreter shifted by the raw immediate or register value, which
is undefined behavior in C when the count is >= the operand width and
trips UBSan. RFC 9669 masks shift counts (0x3f for 64-bit, 0x1f for
32-bit); mask the count in the LSH/RSH/ARSH cases.

* [PATCH v5 2/9] test/bpf: add JSET test with small immediate
From: Stephen Hemminger @ 2026-06-24 17:55 UTC (permalink / raw)
To: dev; +Cc: Stephen Hemminger, Marat Khalili, Konstantin Ananyev
In-Reply-To: <20260624175815.673064-1-stephen@networkplumber.org>
The existing jump test only used a 32-bit JSET mask,
so the broken imm8 encoding of TEST in the x86 JIT was never exercised.
Add a case with a byte-sized mask;
run_test() runs it through the interpreter and the JIT.

* [PATCH v5 1/9] bpf/x86: fix JIT encoding of fixed-width immediates
From: Stephen Hemminger @ 2026-06-24 17:55 UTC (permalink / raw)
To: dev
Cc: Stephen Hemminger, stable, Marat Khalili, Konstantin Ananyev,
Ferruh Yigit
In-Reply-To: <20260624175815.673064-1-stephen@networkplumber.org>
Several places in the x86 JIT size an immediate with imm_size(), which
returns 1 or 4 bytes depending on the value. That is wrong for opcodes
whose immediate width is fixed by the encoding, and it breaks in both
directions.
TEST (0xF7 /0, used for BPF_JSET) has no imm8 form; the immediate is
always 32 bits. For a small mask such as BPF_JSET | BPF_K #0x1,
imm_size() returns 1, so the JIT emits a 1-byte immediate. The CPU
still consumes 4, swallowing 3 bytes of the following Jcc. The
instruction stream desyncs and the program crashes.
ROR and the shifts (0xC1 group) have the opposite problem: their
immediate is always imm8. For a count >= 128, imm_size() returns 4 and
the JIT emits 3 stray bytes, again desyncing the stream.
Size each immediate by its encoding: 32 bits for TEST, 8 bits for ROR
and the shifts.

* [PATCH v5 0/9] bpf: JIT related bug fixes
From: Stephen Hemminger @ 2026-06-24 17:54 UTC (permalink / raw)
To: dev; +Cc: Stephen Hemminger
In-Reply-To: <20260608203322.1116296-1-stephen@networkplumber.org>
While implementing JIT for packet capture ran into several issues:
1. x86 JIT had a pre-existing bug which would crash.
2. The arm64 JIT was missing the packet-access instructions, found
previously [1].
3. Shift counts were not masked to the operand width as RFC 9669
requires: undefined behavior in the interpreter and an encoding
failure in the arm64 JIT.
4. Tests related to JIT were not being run or were missing coverage.
Fixed all of these. Patches are ordered with the most urgent fix (the
x86 crash) first, each fix followed by the test that exercises it. The
arm64 packet-load support is kept ahead of the "check JIT was generated"
patch so the series bisects cleanly on arm64.
The arm64 epilogue branch fix (patch 6) was originally posted by
Christophe Fontaine [1]; that series stalled, so it is carried here with
his authorship.
Changes since v4:
- address Marat's review of the large-shift test: it now checks the
RFC 9669 masked result instead of a sentinel, which surfaced two more
bugs fixed in this version
- mask shift counts to the operand width: the interpreter shifted by
the raw count (UB, trips UBSan; patch 3) and the arm64 JIT overflowed
the UBFM/SBFM immediate (patch 4)
- reorder so the arm64 BPF_ABS/BPF_IND support precedes the "check JIT
was generated" patch, keeping the suite bisectable on arm64

Applied to net-next.
If you want to cleanup some of the checkpatch warnings, I can swap in a new version.

On the duplicate flow devargs; your observation was correct, mlx5 has similar devarg option.
Sorry that I didn't strongly nudge AI in the right direction earlier.
To be clear:
- sxe2 should use same devarg as mlx5 for this "allow_duplicate_pattern"
- default should be 1
- make sure documentation matches flag.
The patch looks much better; but there is a bisection breaking
patch ordering around 6 and 7.
After I pushed AI review to follow that, the review was the following:
(I means Claude AI, not me Stephen)
[PATCH v6 00/23] sxe2 driver feature additions
The flow-duplicate-pattern situation regressed in the wrong direction.
I reread mlx5's allow_duplicate_pattern in light of your "align to mlx5"
guidance and I was wrong to push for removal in v4 and v5. mlx5 has the same
devarg: name allow_duplicate_pattern, default 1, valid 0|1, and both values
expose a real hardware capability that rte_flow itself does not articulate
(value 0 -> EEXIST on duplicate; value 1 -> hardware queues duplicates as
shadow rules that activate when prior rules are deleted). That is not a
"standard API by boot flag" semantics violation as I had read it - it is a
hardware capability switch, and it is documented in doc/guides/nics/mlx5.rst
exactly the way sxe2's was. My v4-v5 push to drop it was based on a
misreading.
Unfortunately the v6 response is to half-remove the devarg in a way that is
worse than either keeping it or removing it cleanly:
[PATCH v6 22/23] flow-duplicate-pattern parsing removed, field left behind
Verified in the assembled tree:
drivers/net/sxe2/sxe2_ethdev.h:138:
uint8_t flow_dup_pattern_mode; /* field still in struct */
drivers/net/sxe2/sxe2_flow.c:806:
rte_flow_error_set(error, EEXIST, ..., NULL,
adapter->devargs.flow_dup_pattern_mode ?
"Duplicate flow pattern." :
"Duplicate flow pattern is not allowed.");
drivers/common/sxe2/sxe2_flow_public.h:603:
uint8_t switch_pattern_dup_allow; /* still in flow metadata */
The devarg's parser, default-setter, register_param_string entry, and
documentation are all gone, but the storage and the read site remain.
The field is zero-initialized and never written, so the ternary always picks
the "is not allowed" string. The hardware-capability path that the value=1
branch used to drive (setting switch_pattern_dup_allow on per-rule metadata)
has no caller now either. None of this is a correctness bug - duplicate
rules are uniformly rejected with EEXIST, which is the conservative
behaviour - but it is dead code that misleads the next reader.
Suggested fix: revert the v5-to-v6 changes that removed the parser and
docs, and instead align with mlx5:
- Rename the devarg to allow_duplicate_pattern (underscore, matching
mlx5's spelling).
- Keep default = 1, matching mlx5's non-HWS default.
- Reuse mlx5's documentation wording in sxe2.rst, adapted for the
switch engine. The "only the first rule takes effect, the next
activates when the first is deleted" semantic from mlx5.rst describes
what the value=1 path does in hardware, and that wording is what was
missing from v5's documentation.
- Keep switch_pattern_dup_allow in flow metadata since it is what
propagates the policy to the hardware programming path.
Or, if the cleaner path is preferred: actually finish the removal. Drop
flow_dup_pattern_mode from struct sxe2_devargs, replace the ternary in
sxe2_flow.c with the single "is not allowed" string, and drop
switch_pattern_dup_allow from struct (or wire it to a compile-time
constant if hardware programming truly needs it). Either direction is
defensible; the v6 in-between state is not.
[PATCH v6 06/23 and 07/23] patches posted in wrong order in the bundle
The bundle has 07/23 (drivers: support RSS feature) before 06/23
(net/sxe2: support L2 filtering and MAC config). git am applies them in
mbox order, so the series fails to apply: 07/23 depends on symbols 06/23
introduces. The fix is just to repost the bundle in numeric order;
contents are byte-identical to v5 for both patches. Worth fixing before
the next post because anyone running git am < bundle.mbox hits this.
Once the mbox order is fixed and the flow-duplicate-pattern situation is
resolved one way or the other, this is ready.
