net: ehea: avoid null pointer dereference

2016-08-22T21:37:11Z

commit 1740c29a46b30a2f157afc473156f157e599d4c2 upstream. ehea_get_port may return NULL. Do not dereference NULL value.

net: do not pretend FRAGLIST support

2014-02-15T19:20:08Z

[ Upstream commit 28e24c62ab3062e965ef1b3bcc244d50aee7fa85 ] Few network drivers really supports frag_list : virtual drivers. Some drivers wrongly advertise NETIF_F_FRAGLIST feature. If skb with a frag_list is given to them, packet on the wire will be corrupt. Remove this flag, as core networking stack will make sure to provide packets that can be sent without corruption.

net/eth/ibmveth: Fixup retrieval of MAC address

2013-05-30T13:34:51Z

commit 13f85203e1060da83d9ec1c1c5a63343eaab8de4 upstream. Some ancient pHyp versions used to create a 8 bytes local-mac-address property in the device-tree instead of a 6 bytes one for veth. The Linux driver code to deal with that is an insane hack which also happens to break with some choices of MAC addresses in qemu by testing for a bit in the address rather than just looking at the size of the property. Sanitize this by doing the latter instead. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: David S. Miller Signed-off-by: Ben Hutchings

ibmveth: Fix alignment of rx queue bug

2012-09-19T14:05:15Z

commit d90c92fee89ccd75ef2646f3bde0b4c0450666c3 upstream. This patch fixes a bug found by Nish Aravamudan (https://lkml.org/lkml/2012/5/15/220) where the driver is not following the spec (it is not aligning the rx buffer on a 16-byte boundary) and the hypervisor aborts the registration, making the device unusable. The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461) to replace the kmalloc+map for a single call to dma_alloc_coherent() because that function always aligns to a 16-byte boundary. The stable trees will run into this bug whenever the rx buffer kmalloc call returns something not aligned on a 16-byte boundary. Signed-off-by: Santiago Leon Signed-off-by: David S.

ehea: Reduce memory usage in buffer pools

2011-11-24T00:14:20Z

Now that we enable multiqueue by default the ehea driver is using quite a lot of memory for its buffer pools. With 4 queues we consume 64MB in the jumbo packet ring, 16MB in the medium packet ring and 16MB in the tiny packet ring. We should only fill the jumbo ring once the MTU is increased but for now halve it's size so it consumes 32MB. Also reduce the tiny packet ring, with 4 queues we had 16k entries which is overkill.

net: add skb frag size accessors

2011-10-19T07:10:46Z

To ease skb->truesize sanitization, its better to be able to localize all references to skb frags size. Define accessors : skb_frag_size() to fetch frag size, and skb_frag_size_{set|add|sub}() to manipulate it. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
