vmxnet3: use correct tcp hdr length when packet is encapsulated

2020-08-19T06:16:23+00:00

[ Upstream commit 8a7f280f29a80f6e0798f5d6e07c5dd8726620fe ] Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload support") added support for encapsulation offload. However, while calculating tcp hdr length, it does not take into account if the packet is encapsulated or not. This patch fixes this issue by using correct reference for inner tcp header.

net: vmxnet3: fix possible buffer overflow caused by bad DMA value in vmxnet3_get_rss()

2020-06-22T07:30:57+00:00

[ Upstream commit 3e1c6846b9e108740ef8a37be80314053f5dd52a ] The value adapter->rss_conf is stored in DMA memory, and it is assigned to rssConf, so rssConf->indTableSize can be modified at anytime by malicious hardware. Because rssConf->indTableSize is assigned to n, buffer overflow may occur when the code "rssConf->indTable[n]" is executed. To fix this possible bug, n is checked after being used.

net: Use skb_frag_off accessors

Use accessor functions for skb fragment's page_offset instead of direct references, in preparation for bvec conversion. Signed-off-by: Jonathan Lemon Signed-off-by: David S. Miller

net: Use skb accessors in network drivers

2019-07-23T03:47:56+00:00

In preparation for unifying the skb_frag and bio_vec, use the fine accessors which already exist and use skb_frag_t instead of struct skb_frag_struct. Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: David S. Miller

vmxnet3: Remove call to memset after dma_alloc_coherent

2019-07-15T18:06:27+00:00

In commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*"), dma_alloc_coherent has already zeroed the memory. So memset is not needed. Signed-off-by: Fuqian Huang Signed-off-by: David S. Miller

vmxnet3: turn off lro when rxcsum is disabled

2019-06-05T03:05:56+00:00

Currently, when rx csum is disabled, vmxnet3 driver does not turn off lro, which can cause performance issues if user does not turn off lro explicitly. This patch adds fix_features support which is used to turn off LRO whenever RXCSUM is disabled. Signed-off-by: Ronak Doshi Acked-by: Rishi Mehta Signed-off-by: David S. Miller

net: ipv4: provide __rcu annotation for ifa_list

2019-06-03T01:08:36+00:00

ifa_list is protected by rcu, yet code doesn't reflect this. Add the __rcu annotations and fix up all places that are now reported by sparse. I've done this in the same commit to not add intermediate patches that result in new warnings. Reported-by: Eric Dumazet Signed-off-by: Florian Westphal Signed-off-by: David S. Miller

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37+00:00

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig Signed-off-by: Luis Chamberlain [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig

S390 bpf_jit.S is removed in net-next and had changes in 'net', since that code isn't used any more take the removal. TLS data structures split the TX and RX components in 'net-next', put the new struct members from the bug fix in 'net' into the RX part. The 'net-next' tree had some reworking of how the ERSPAN code works in the GRE tunneling code, overlapping with a one-line headroom calculation fix in 'net'. Overlapping changes in __sock_map_ctx_update_elem(), keep the bits that read the prog members via READ_ONCE() into local variables before using them. Signed-off-by: David S. Miller
