net: move skb->xmit_more hint to softnet data

2019-04-02T01:35:02Z

There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.

enic: fix build warning without CONFIG_CPUMASK_OFFSTACK

2019-03-07T17:41:08Z

The enic driver relies on the CONFIG_CPUMASK_OFFSTACK feature to dynamically allocate a struct member, but this is normally intended for local variables. Building with clang, I get a warning for a few locations that check the address of the cpumask_var_t: drivers/net/ethernet/cisco/enic/enic_main.c:122:22: error: address of array 'enic->msix[i].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] As far as I can tell, the code is still correct, as the truth value of the pointer is what we need in this configuration. To get rid of the warning, use cpumask_available() instead of checking the pointer directly.

enic: fix checksum validation for IPv6

2019-02-01T22:41:42Z

In case of IPv6 pkts, ipv4_csum_ok is 0. Because of this, driver does not set skb->ip_summed. So IPv6 rx checksum is not offloaded. Signed-off-by: Govindarajulu Varadarajan Signed-off-by: David S. Miller

net: core: dev: Add extack argument to dev_open()

2018-12-06T21:26:06Z

In order to pass extack together with NETDEV_PRE_UP notifications, it's necessary to route the extack to __dev_open() from diverse (possibly indirect) callers. One prominent API through which the notification is invoked is dev_open(). Therefore extend dev_open() with and extra extack argument and update all users. Most of the calls end up just encoding NULL, but bond and team drivers have the extack readily available.

net: cisco: enic: Replace GFP_ATOMIC with GFP_KERNEL

2018-08-04T20:08:06Z

vnic_dev_register(), vnic_rq_alloc_bufs() and vnic_wq_alloc_bufs() are never called in atomic context. They call kzalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai Acked-by: Govindarajulu Varadarajan Signed-off-by: David S.

enic: do not call enic_change_mtu in enic_probe

2018-07-31T21:42:49Z

In commit ab123fe071c9 ("enic: handle mtu change for vf properly") ASSERT_RTNL() is added to _enic_change_mtu() to prevent it from being called without rtnl held. enic_probe() calls enic_change_mtu() without rtnl held. At this point netdev is not registered yet. Remove call to enic_change_mtu and assign the mtu to netdev->mtu.

enic: handle mtu change for vf properly

2018-07-29T02:04:38Z

When driver gets notification for mtu change, driver does not handle it for all RQs. It handles only RQ[0]. Fix is to use enic_change_mtu() interface to change mtu for vf. Signed-off-by: Govindarajulu Varadarajan Signed-off-by: David S. Miller

enic: do not overwrite error code

2018-06-19T23:10:13Z

In failure path, we overwrite err to what vnic_rq_disable() returns. In case it returns 0, enic_open() returns success in case of error.
