Re: [PATCH net-next v3] net/ionic: avoid OOB TX partner lookup for hwstamp RXQ

On 8/13/26 10:37 AM, Anand Khoje wrote:

The dedicated hardware timestamp RX queue is allocated with q->index
equal to lif->ionic->nrxqs_per_lif. The normal txqcqs array only
contains the regular queue pairs, so using that index to set rxq->partner
can read one entry past txqcqs[] and then write through the derived
pointer.
Only link RX/TX partners for normal queue-pair indexes. Leave the hwstamp
RX queue unpaired, and make the XDP_TX path abort cleanly if an RX queue
has no TX partner.

This is net material, you should have set accordingly the target tree
into the subj prefix. Also your SoB should come last.

No need to resend just for this, but keep in mind for future submissions.
