RDMA/hfi1: Propagate sdma_txinit_ahg() errors
Published Sep 17, 2026

HIGHCVSS 3.1
EPSS 0.18%
Description
set_txreq_header_ahg() ignores the return value of sdma_txinit_ahg().
If sdma_txinit_ahg() fails, it returns before initializing tx->txreq. However, set_txreq_header_ahg() ignores the error and returns the AHG change count, causing the caller to continue processing the request as though initialization had succeeded.
Propagate sdma_txinit_ahg() failures to the caller and abort request processing when initialization fails.
