net/ionic: avoid OOB TX partner lookup for hwstamp RXQ

2026-08-18T11:14:44+00:00

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.

ionic: fix completion descriptor access with 2x desc size

2026-08-17T19:58:46+00:00

The old ionic_rx_service() and ionic_tx_service() used array indexing to access completion descriptors: comp = &((struct ionic_rxq_comp *)cq->base)[cq->tail_idx]; This assumes the stride is sizeof(struct ionic_rxq_comp) = 16 bytes. However, when the IONIC_Q_F_2X_CQ_DESC flag is set, the actual completion descriptor size is 32 bytes (2 * sizeof(comp)), and the completion itself is located at the end of that 32-byte slot. Array indexing with a 16-byte stride would access the wrong offset. Use pointer arithmetic that accounts for the actual descriptor size from cq->desc_size: comp = cq->base + cq->desc_size * cq->tail_idx + cq->desc_size - sizeof(*comp); This correctly calculates the completion location regardless of descriptor size. For the common case where desc_size equals sizeof(*comp), use array indexing in a likely() fast path to avoid performance regression.

ionic: add missing dma_rmb() after the completion publish check

2026-08-17T19:58:46+00:00

Each completion service routine tests a device-written publish flag and then reads the rest of the descriptor with nothing ordering those loads. A control dependency does not order loads, so a weakly ordered CPU may satisfy the payload reads from a cache line state observed before the flag became valid. Add the barrier to all four completion paths.

net: ionic: Add PHC state page for user space access

2026-07-22T08:53:36+00:00

Add a page associated with the PHC that can be mapped to user space, allowing applications to access hardware timestamp information. In order to synchronize between kernel and user space, a sequence number is incremented at the beginning and end of each update. An odd number means the data is being updated while an even number means the update is complete. To guarantee that the data structure was accessed atomically, user space will: repeat: seq1 = goto if odd seq2 = if seq1 != seq2 goto repeat This mechanism acts as a guard against reading invalid state during concurrent updates.

net: ionic: register PHC for rdma timestamping

2026-07-22T08:53:36+00:00

Currently, the driver only registers the PTP Hardware Clock (PHC) if Ethernet hardware timestamping is supported. Update the registration logic to register the PHC if the device supports either Ethernet hardware timestamping or RDMA completion timestamping.
