2018-04-21rapidio: fix rio_dma_transfer error handlingIoan Nicu1-10/+9
Some of the mport_dma_req structure members were initialized late inside the do_dma_request() function, just before submitting the request to the dma engine. But we have some error branches before that. In case of such an error, the code would return on the error path and trigger the calling of dma_req_free() with a req structure which is not completely initialized. This causes a NULL pointer dereference in dma_req_free(). This patch fixes these error branches by making sure that all necessary mport_dma_req structure members are initialized in rio_dma_transfer() immediately after the request structure gets allocated.

2018-04-20Revert "libnvdimm, of_pmem: workaround OF_NUMA=n build error"Dan Williams1-2/+1
With commit df3f126482db ("libnvdimm, of_pmem: use dev_to_node() instead of of_node_to_nid()") it is now possible to allow of_pmem to be built as a module as originally implemented. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2018-04-20libnvdimm, of_pmem: use dev_to_node() instead of of_node_to_nid()Rob Herring1-1/+1
Remove the direct dependency on of_node_to_nid() by using dev_to_node() instead. Any DT platform device will have its NUMA node id set when the device is created. With this, commit 291717b6fbdb ("libnvdimm, of_pmem: workaround OF_NUMA=n build error") can be reverted.

2018-04-19bnxt_en: Fix memory fault in bnxt_ethtool_init()Vasundhara Volam2-24/+27
In some firmware images, the length of BNX_DIR_TYPE_PKG_LOG nvram type could be greater than the fixed buffer length of 4096 bytes allocated by the driver. This was causing HWRM_NVM_READ to copy more data to the buffer than the allocated size, causing general protection fault. Fix the issue by allocating the exact buffer length returned by HWRM_NVM_FIND_DIR_ENTRY, instead of 4096. Move the kzalloc() call into the bnxt_get_pkgver() function.

Programming vids (adding or removing them) still passes guest-endian values in the DMA buffer. That's wrong if guest is big-endian and when virtio 1 is enabled.

2018-04-19virtio_net: split out ctrl bufferMichael S. Tsirkin1-29/+39
When sending control commands, virtio net sets up several buffers for DMA. The buffers are all part of the net device which means it's actually allocated by kvmalloc so it's in theory (on extreme memory pressure) possible to get a vmalloc'ed buffer which on some platforms means we can't DMA there. Fix up by moving the DMA buffers into a separate structure. Reported-by: Mikulas Patocka <mpatocka@redhat.com> Suggested-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Michael S.

2018-04-19net: hns: Avoid action name truncationdann frazier1-1/+1
When longer interface names are used, the action names exposed in /proc/interrupts and /proc/irq/* maybe truncated. For example, when using the predictable name algorithm in systemd on a HiSilicon D05, I see: ubuntu@d05-3:~$ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //' enahisic2i0-tx0 enahisic2i0-tx1 [...] enahisic2i0-tx8 enahisic2i0-tx9 enahisic2i0-tx1 enahisic2i0-tx1 enahisic2i0-tx1 enahisic2i0-tx1 enahisic2i0-tx1 enahisic2i0-tx1 Increase the max ring name length to allow for an interface name of IFNAMSIZE. After this change, I now see: $ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //' enahisic2i0-tx0 enahisic2i0-tx1 enahisic2i0-tx2 [...] enahisic2i0-tx8 enahisic2i0-tx9 enahisic2i0-tx10 enahisic2i0-tx11 enahisic2i0-tx12 enahisic2i0-tx13 enahisic2i0-tx14 enahisic2i0-tx15 Signed-off-by: dann frazier <dann.frazier@canonical.com> Signed-off-by: David S.

2018-04-19vmxnet3: fix incorrect dereference when rxvlan is disabledRonak Doshi2-6/+15
vmxnet3_get_hdr_len() is used to calculate the header length which in turn is used to calculate the gso_size for skb. When rxvlan offload is disabled, vlan tag is present in the header and the function references ip header from sizeof(ethhdr) and leads to incorrect pointer reference. This patch fixes this issue by taking sizeof(vlan_ethhdr) into account if vlan tag is present and correctly references the ip hdr.

When the last rmnet device attached to a real device is removed, the real device is unregistered from rmnet. As a result, the real device lookup fails resulting in a warning when the fill_info handler is called as part of the rmnet device unregistration. Fix this by returning the rmnet flags as 0 when no real device is present.
