Subject: [PATCH v5 0/3] Support PERF MGMT for RXE
Date: Wed,  8 Apr 2026 08:09:53 +0800	[thread overview]
Message-ID: <20260408000956.486522-1-zhenwei.pi@linux.dev> (raw)

v5:
- remove patch "RDMA/core: Fix memory free for GID table", it was
  applied by Jason separately.
- suggested by Yanjun, use 'skb_network_offset' to calculate the
  length of received packets.

v4:
- drop rxe_ib_device_get_netdev and RXE_PORT, use 1 instead
- avoid UAF to get skb length
- remove one-line wrapper rxe_counter_get, use atomic64_read instead
- fix memory free for GID table, this is a new patch in this series.

v3:
- merge 'RDMA/rxe: use rxe_counter_get' into previous commit
- zero *out* MAD memory
- return success with error status rather than failure to avoid
  uplayer hang

v2:
- Fix overflow for PMA counter *link_downed_counter*
- Use *rxe_counter_get* instead of *atomic64_read* for hw-counters

v1:
Support PERF MGMT for RXE, add sent/received bytes for RXE counters,
also improve coding style.

zhenwei pi (3):
  RDMA/rxe: remove rxe_ib_device_get_netdev() and RXE_PORT
  RDMA/rxe: add SENT/RCVD bytes
  RDMA/rxe: support perf mgmt GET method
