* [PATCH v7 2/6] eal: use request ID instead of pointers
From: Anatoly Burakov @ 2026-06-26 10:33 UTC (permalink / raw)
To: dev, Jianfeng Tan
In-Reply-To: <cover.1782469943.git.anatoly.burakov@intel.com>
Initial implementation of async IPC request handling was using request
pointers directly. Because of the nature of how IPC is meant to work and
that requests ownership is disconnected from their creation (as in, freeing
a request may happen due to timeout, or due to received response, or due
to rollback because of a later failure), using pointers as identity is not
safe.
Use numeric request ID for async request lookup instead. This way, we can
safely free requests even if we are already waiting on responses/timeouts
for them, as the pointers themselves will not be referenced directly by
the response/timeout.
Fixes: f05e26051c15 ("eal: add IPC asynchronous request")

* [PATCH v7 1/6] eal: fix wrong log message in async IPC request

In-Reply-To: <cover.1782469943.git.anatoly.burakov@intel.com>
The allocation failure log message in mp_request_async() says "sync
request" but the function handles asynchronous requests.
Fix the log to say "async request".

* [PATCH v7 0/6] IPC fixes
From: Anatoly Burakov @ 2026-06-26 10:33 UTC (permalink / raw)
To: dev
In-Reply-To: <740b39c5098b4d40cafb9881ad70865a3c889012.1773936429.git.anatoly.burakov@intel.com>
Coverity has reported (issue ID 501503) a memory leak, but there
actually were a few more problems with IPC than that. This patchset
addresses said problems.
1. Using pointer as async request identity is unsafe
Because asynchronous requests can fail at arbitrary points while
having arbitrary number of requests or alarms already in flight,
using pointer as request identity can create use-after-free risks.
Patchset replaces this with using numeric request ID instead.
2. Alarm cancel can deadlock
Async request handler may attempt to cancel the alarm, but an alarm
might have already been in progress blocking on the same lock that
is held by async request, leading to a deadlock. Patchset removes
the alarm cancel call, and allows the alarm to fire. This is fine,
because due to fix #1 the worst that can happen from calling stale
alarm is a noop, as request ID would not be found.
3. Memory leaks
There are a couple of memory leaks in failure paths. Patchset fixes
those.
4. Zero-peer async request does not trigger alarm
When async requests are performed but no peers exist, we created
a dummy request and put it on the queue, but we never set the
dummy alarm that is supposed to handle that request. Patchset adds
the alarm set in dummy paths where none was present before.
v7:
- Moved request ID reservation till after allocation
- Added build check for request ID size matching pointer size
- Moved comment about minimum delay alarm from patch 4 to patch 6
Note: AI review had a bunch of false positive "errors", all of them
looked at and verified as such.
v6:
Moved pieces around, namely:
1) apply request ID refactor first as a standalone patch
2) fix the deadlock immediately after
3) fix memory leaks next
4) add missing callback as a final step
Contents of the patchset remain the same.
Anatoly Burakov (6):
eal: fix wrong log message in async IPC request
eal: use request ID instead of pointers
eal: avoid deadlock in async IPC alarm callback
eal: fix async IPC memory leaks on partial failure
eal: fix memory leak in async IPC secondary path
eal: fix async IPC callback not fired when no peers

From: Dawid Wesierski @ 2026-06-26 10:22 UTC (permalink / raw)

Thanks again for the review,
For v6 I have added the input validation we ccheck if the timestamp
PCAPNG_TSC_FLAG is not set on caller-provided input.
Regarding API versioning my concern is around source-level compatibility.
Any application that calls rte_pcapng_copy() would need to be updated to
pass the additional timestamp argument right?
Is breaking source-level compatibility for existing callers of
rte_pcapng_copy() acceptable here?

Indeed calling this function with dev->mem uninitialized is caused by
some init/deinit state bug, but I still think we should keep this check
in for added safety.
I will follow up with a v2 to remove the redundant () and also I will
look into fixing the root cause.

From: Jun Yang <jun.yang@nxp.com>
Track allocated BPIDs in a static per-BPID flag table and register a
driver destructor that releases any BPIDs still marked as in use at
process exit. This prevents BPID leaks when an application exits without
calling rte_mempool_free(). Also tune the per-lcore mempool cache flush
threshold to match the hardware bulk release size (DPAA_MBUF_MAX_ACQ_REL)
so that buffers are returned to HW in optimal burst sizes.

* [PATCH v5 14/19] net/dpaa: optimize FMC MAC type parsing
From: Hemant Agrawal @ 2026-06-26 6:56 UTC (permalink / raw)
To: stephen, david.marchand, dev; +Cc: Jun Yang
In-Reply-To: <20260626065655.279742-1-hemant.agrawal@nxp.com>
From: Jun Yang <jun.yang@nxp.com>
For ls104xa, MAC9 and MAC10's type could be either of 10G/2.5G/1G
up to serdes configuration, MAC index should be identified by
port name instead of parsing MAC type and port number.

* [PATCH v5 13/19] bus/dpaa: improve log macro and fix bus detection
From: Hemant Agrawal @ 2026-06-26 6:56 UTC (permalink / raw)
To: stephen, david.marchand, dev
In-Reply-To: <20260626065655.279742-1-hemant.agrawal@nxp.com>
Replace DPAA_BUS_LOG(LEVEL, ...) calls with shorthand macros
(DPAA_BUS_INFO, DPAA_BUS_ERR, DPAA_BUS_WARN, DPAA_BUS_DEBUG) for
consistency across the driver.
Move bus detection (sysfs path check), portal key creation and
dpaa_bus.detected guard into dpaa_bus_dev_compare() so that bus
probe is properly gated on hardware presence.

Remove the redundant qman_shutdown_fq() call from
dpaa_eth_rx_queue_setup(). The FQ is shut down during device stop,
so calling it again at queue setup time is unnecessary and may
interfere with a clean queue initialization.

* [PATCH v5 07/19] bus/dpaa: improve FQ shutdown with channel validation
From: Hemant Agrawal @ 2026-06-26 6:56 UTC (permalink / raw)
To: stephen, david.marchand, dev; +Cc: Jun Yang
In-Reply-To: <20260626065655.279742-1-hemant.agrawal@nxp.com>
From: Jun Yang <jun.yang@nxp.com>
Fix hardcoded channel range check by using DTS-derived pool
channel start/end values. Add validation that the portal's
affine channel matches the FQ's channel for pool-channel FQs,
and only restore SDQCR when it was actually changed.

Calculate the maximum BPID dynamically from the device tree
configuration instead of using a hardcoded value. This ensures
correct operation across different DPAA hardware configurations.

* [PATCH v5 19/19] net/dpaa: add ONIC port checks
From: Hemant Agrawal @ 2026-06-26 6:56 UTC (permalink / raw)
To: stephen, david.marchand, dev; +Cc: Vanshika Shukla
In-Reply-To: <20260626065655.279742-1-hemant.agrawal@nxp.com>
From: Vanshika Shukla <vanshika.shukla@nxp.com>
Add fman_onic MAC type handling to get_rx_port_type() so that ONIC
and offline-internal ports are mapped to OH_OFFLINE_PARSING, consistent
with how the VSP port configuration handles these types. Without this,
ONIC ports used an incorrect port type in flow configuration, leading
to failed FMC operations.

* [PATCH v5 18/19] dma/dpaa: add SG data validation and ERR050757 fix
From: Hemant Agrawal @ 2026-06-26 6:56 UTC (permalink / raw)
To: stephen, david.marchand, dev; +Cc: Gagandeep Singh
In-Reply-To: <20260626065655.279742-1-hemant.agrawal@nxp.com>
From: Gagandeep Singh <g.singh@nxp.com>
Add scatter-gather (SG) support to the QDMA driver, enabled by default
via the s_sg_enable flag. Add optional data validation mode controlled
by the s_data_validation flag for debugging transfer correctness.
Add a workaround for hardware errata ERR050757: when
RTE_DMA_DPAA_ERRATA_ERR050757 is defined, configure the source frame
descriptor with stride settings (sss/ssd = FSL_QDMA_CMD_SS_ERR050757_LEN)
to force PCI read transactions to stay within the errata-safe length
limit, preventing data corruption on affected silicon.

* [PATCH v5 16/19] drivers: optimize DPAA multi-entry buffer pool operations
From: Hemant Agrawal @ 2026-06-26 6:56 UTC (permalink / raw)
To: stephen, david.marchand, dev; +Cc: Jun Yang
In-Reply-To: <20260626065655.279742-1-hemant.agrawal@nxp.com>
From: Jun Yang <jun.yang@nxp.com>
Replace the hardcoded buffer acquire count of 8 with the FSL_BM_BURST_MAX
constant when acquiring buffers from the buffer pool. Use a single
bm_hw_buf_desc structure for HW initialization of the first entry and copy
it to remaining entries, ensuring consistent HW descriptor state across
all entries in the pool.
