In-Reply-To: <20260611142029.3351415-1-rbhansali@marvell.com>
From: Aarnav JP <ajp@marvell.com>
Fix NULL pointer dereferences (roc_dev.c, roc_npa.c, roc_nix_inl.c),
resource leaks in error paths (roc_dev.c, roc_dpi.c, roc_ree.c,
roc_nix.c, roc_emdev.c), uninitialized variables (roc_npa_debug.c,
roc_emdev.c), array out-of-bounds access (roc_npc_utils.c, roc_emdev.c),
bitwise operand size mismatches (roc_mbox.h, roc_emdev_irq.c), and
format string type mismatches (roc_cpt_debug.c).
Fixes: 5d8ff275433a ("common/cnxk: fix race condition between up and down mailbox")
Fixes: 9a92937cf0c8 ("common/cnxk: fix possible out-of-bounds access")
Fixes: 7557e3f5b9fa ("common/cnxk: replace direct API usage in REE")
Fixes: 3fdf3e53f3c4 ("common/cnxk: enable CPT CQ for inline IPsec inbound")
Fixes: c758279fee32 ("common/cnxk: support debug dump to file")

Add upper-bound checks before memcpy into encr_key[32]
in roc_se_ciph_key_set() to prevent buffer overflow into
adjacent encr_iv[16]. Covers all write paths including
AES-DOCSISBPI and DES-DOCSISBPI branches that bypass
the generic copy via goto.

* [PATCH v2 13/22] net/cnxk: derive ethdev from SA for inbound CPT CQ events

From: Aarnav JP <ajp@marvell.com>
With inbound CPT CQ events, port_id is unavailable since the inline
device has no roc_nix. Resolve eth_dev for inbound CQ events in the
cn20k PMD callback via the SA private data chain instead of relying
on port_id.
Add an eth_dev back pointer to cnxk_eth_sec_sess, populated at
session creation, to complete the SA-to-ethdev lookup path
(inb_priv->eth_sec->eth_dev).

* [PATCH v2 12/22] net/cnxk: fix unsigned integer underflow in LSO calculation
From: Rahul Bhansali @ 2026-06-11 14:20 UTC (permalink / raw)

In-Reply-To: <20260611142029.3351415-1-rbhansali@marvell.com>
From: Aarnav JP <ajp@marvell.com>
Replace branchless mask-based selection with a ternary operator
to resolve Coverity integer underflow warning. The expression
-(!w1.il3type) assigned -1 to a uint64_t variable, which is
well-defined but flagged as an unsigned integer underflow.
Coverity issue: 502004
Fixes: 19f3af2371a7 ("net/cnxk: add Tx burst for CN10K")
Fixes: 39dc567c1955 ("net/cnxk: add Tx burst for CN9K")
Fixes: 006c1daa89b9 ("net/cnxk: support Tx burst scalar for CN20K")

CPT Completion Queue is supported on CN20K and provides
hardware-based completion notification, eliminating the
need for software polling. Change the default value of
cpt_cq_enable devarg from 0 to 1 so that CPT CQ is
enabled by default.

Update the inbound SA pkind using roc_npc_skip_size_pkind_get()
during session create and session update for both CN10K and CN20K.
This ensures the CPT second pass uses the correct pkind when
skip size is configured, retaining the default pkind otherwise.

+
+ When the switch header type is set to "skip_size", the number of bytes to
+ skip before the Ethernet header can be configured using ``skip_size_info``
+ ``devargs`` parameter. The value is in hexadecimal format and the valid

Calling rte_cryptodev_pmd_get_named_dev() is enough to retrieve the
crypto device object.
This leaves no user of the crypto_dev field in the dpaa device object.

* [PATCH 0/3] Cleanup rte_dpaa_device
From: David Marchand @ 2026-06-11 13:07 UTC (permalink / raw)
To: dev; +Cc: hemant.agrawal
Similar to the cleanup on the FSLMC bus, the DPAA bus device can
be cleaned.
The rte_dpaa_device object keeps track of a device class object
(cryptodev, dmadev, ethdev) which is a layer violation.
Make use of the device class respective infrastructure and remove those
back references.
Disclaimer: this series is untested as I don't have the hardware.
I only based those changes on look at the code and other drivers.

Patch applied to next-net-intel with title reworded and some additional
text on the commit log. Anurag and Ciara, please review the applied commit
log to check it is ok with you.

Hi Bruce, I believe there 2 underlying issues being fixed here:
1. Ensuring LSC event is sent to the application AFTER configuring
watchdog/no_poll state.
2. Ensuring watchdog is re-armed on LSC event, if a reset is detected.
(Before it was only re-armed if link was down).
The comment in the new function iavf_handle_link_change_event explains
the reasoning. Perhaps an update to the commit message could be pulled
from there.
Thanks,
Ciara
