From df807a19957c2917fd5a4f5812e240a250066742 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 30 Nov 2017 14:23:54 +0000 Subject: [PATCH] chcr: ensure cntrl is initialized to fix bit-wise or'ing of garabage data In the case where skb->ip_summed != CHECKSUM_PARTIAL then cntrl contains garbage value and this is possibly being bit-wise or'd and stored into cpl->ctrl1. Fix this by initializing cntrl to zero. Cleans up clang warning: drivers/crypto/chelsio/chcr_ipsec.c:374:9: warning: The left expression of the compound assignment is an uninitialized value. The computed value will also be garbage Fixes: 6dad4e8ab3ec ("chcr: Add support for Inline IPSec") Signed-off-by: Colin Ian King Signed-off-by: Herbert Xu --- drivers/crypto/chelsio/chcr_ipsec.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/crypto/chelsio/chcr_ipsec.c b/drivers/crypto/chelsio/chcr_ipsec.c index a0f003ffd1f4..64a030f8fb21 100644 --- a/drivers/crypto/chelsio/chcr_ipsec.c +++ b/drivers/crypto/chelsio/chcr_ipsec.c @@ -350,7 +350,7 @@ inline void *copy_cpltx_pktxt(struct sk_buff *skb, struct port_info *pi; struct sge_eth_txq *q; struct cpl_tx_pkt_core *cpl; - u64 cntrl; + u64 cntrl = 0; u32 ctrl0, qidx; pi = netdev_priv(dev);
