Subject: [PATCH v4 0/4] Support PERF MGMT for RXE
Date: Mon, 6 Apr 2026 21:28:25 +0800 [thread overview]
Message-ID: <20260406132830.435381-1-zhenwei.pi@linux.dev> (raw)
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.
