Hi all, Today's linux-next merge of the bpf-next tree got a conflict in: drivers/net/ethernet/intel/ice/ice_xsk.c between commit: 675f176b4dcc ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net") from the net-next tree and commit: aa1d3faf71a6 ("ice: Robustify cleaning/completing XDP Tx buffers") from the bpf-next tree. I fixed it up (I guessed - see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc drivers/net/ethernet/intel/ice/ice_xsk.c index b2d96ae5668c,917c75e530ca..000000000000 --- a/drivers/net/ethernet/intel/ice/ice_xsk.c +++ b/drivers/net/ethernet/intel/ice/ice_xsk.c @@@ -629,29 -613,28 +629,30 @@@ static void ice_clean_xdp_irq_zc(struc last_rs = xdp_ring->next_to_use ? xdp_ring->next_to_use - 1 : cnt - 1; tx_desc = ICE_TX_DESC(xdp_ring, last_rs); - if (tx_desc->cmd_type_offset_bsz & - cpu_to_le64(ICE_TX_DESC_DTYPE_DESC_DONE)) { + if ((tx_desc->cmd_type_offset_bsz & + cpu_to_le64(ICE_TX_DESC_DTYPE_DESC_DONE))) { if (last_rs >= ntc) - xsk_frames = last_rs - ntc + 1; + completed_frames = last_rs - ntc + 1; else - xsk_frames = last_rs + cnt - ntc + 1; + completed_frames = last_rs + cnt - ntc + 1; } - if (!xsk_frames) + if (!completed_frames) return; - if (likely(!xdp_ring->xdp_tx_active)) + if (likely(!xdp_ring->xdp_tx_active)) { + xsk_frames = completed_frames; goto skip; + } ntc = xdp_ring->next_to_clean; - for (i = 0; i < xsk_frames; i++) { + for (i = 0; i < completed_frames; i++) { tx_buf = &xdp_ring->tx_buf[ntc]; - if (tx_buf->raw_buf) { + if (tx_buf->type == ICE_TX_BUF_XSK_TX) { + tx_buf->type = ICE_TX_BUF_EMPTY; - xsk_buff_free(tx_buf->xdp); - xdp_ring->xdp_tx_active--; + ice_clean_xdp_tx_buf(xdp_ring, tx_buf); + tx_buf->raw_buf = NULL; } else { xsk_frames++; }
