From c3211708cf721163733f03330bdb579d8c0f689b Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot <jjhiblot@ti.com> Date: Thu, 9 Aug 2018 16:17:41 +0200 Subject: [PATCH] net: eth-uclass: Fix for DM USB ethernet support When a USB ethernet device is halted, the device driver is removed. When this happens the uclass private memory is freed and uclass_priv is set to NULL. This causes a data abort when uclass_priv->state is then set to ETH_STATE_PASSIVE. Fix it by checking if uclass_priv is NULL before setting uclass_priv->state Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com> --- net/eth-uclass.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/net/eth-uclass.c b/net/eth-uclass.c index fa3f5497a2..91d861be41 100644 --- a/net/eth-uclass.c +++ b/net/eth-uclass.c @@ -312,7 +312,8 @@ void eth_halt(void) eth_get_ops(current)->stop(current); priv = current->uclass_priv; - priv->state = ETH_STATE_PASSIVE; + if (priv) + priv->state = ETH_STATE_PASSIVE; } int eth_is_active(struct udevice *dev) -- 2.39.5
