2018-04-20rapidio: 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.

MAP_SYNC is a nop for device-dax. Allow MAP_SYNC to succeed on device-dax to eliminate special casing between device-dax and fs-dax as to when the flag can be specified. Device-dax users already implicitly assume that they do not need to call fsync(), and this enables them to explicitly check for this capability.

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.

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.

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.

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.

ACS Feature is currently enabled for GMAC >= 4 but the llc_snap status is never checked in descriptor rx_status callback. This will cause stmmac to always strip packets even that ACS feature is already stripping them.

2018-04-18tun: fix vlan packet truncationBjørn Mork1-6/+1
Bogus trimming in tun_net_xmit() causes truncated vlan packets. skb->len is correct whether or not skb_vlan_tag_present() is true. There is no more reason to adjust the skb length on xmit in this driver than any other driver. tun_put_user() adds 4 bytes to the total for tagged packets because it transmits the tag inline to userspace. This is similar to a nic transmitting the tag inline on the wire. Reproducing the bug by sending any tagged packet through back-to-back connected tap interfaces: socat TUN,tun-type=tap,iff-up,tun-name=in TUN,tun-type=tap,iff-up,tun-name=out & ip link add link in name in.20 type vlan id 20 ip addr add 10.9.9.9/24 dev in.20 ip link set in.20 up tshark -nxxi in -f arp -c1 2>/dev/null & tshark -nxxi out -f arp -c1 2>/dev/null & ping -c 1 10.9.9.5 >/dev/null 2>&1 The output from the 'in' and 'out' interfaces are different when the bug is present: Capturing on 'in' 0000 ff ff ff ff ff ff 76 cf 76 37 d5 0a 81 00 00 14 ......v.v7...... 0010 08 06 00 01 08 00 06 04 00 01 76 cf 76 37 d5 0a ..........v.v7.. 0020 0a 09 09 09 00 00 00 00 00 00 0a 09 09 05 ..............

2018-04-18drm/i915: Fix LSPCON TMDS output buffer enabling from low-power stateImre Deak1-7/+32
LSPCON adapters in low-power state may ignore the first I2C write during TMDS output buffer enabling, resulting in a blank screen even with an otherwise enabled pipe. Fix this by reading back and validating the written value a few times. The problem was noticed on GLK machines with an onboard LSPCON adapter after entering/exiting DC5 power state. Doing an I2C read of the adapter ID as the first transaction - instead of the I2C write to enable the TMDS buffers - returns the correct value. Based on this we assume that the transaction itself is sent properly, it's only the adapter that is not ready for some reason to accept this first write after waking from low-power state. In my case the second I2C write attempt always succeeded.

2018-04-18drm/i915/bios: filter out invalid DDC pins from VBT child devicesJani Nikula1-4/+9
The VBT contains the DDC pin to use for specific ports. Alas, sometimes the field appears to contain bogus data, and while we check for it later on in intel_gmbus_get_adapter() we fail to check the returned NULL on errors. Oops results. The simplest approach seems to be to catch and ignore the bogus DDC pins already at the VBT parsing phase, reverting to fixed per port default pins. This doesn't guarantee display working, but at least it prevents the oops. And we continue to be fuzzed by VBT. One affected machine is Dell Latitude 5590 where a BIOS upgrade added invalid DDC pins.

2018-04-18drm/i915/pmu: Inspect runtime PM state more carefully while estimating RC6Tvrtko Ursulin1-10/+27
While thinking about sporadic failures of perf_pmu/rc6-runtime-pm* tests on some CI machines I have concluded that: a) the PMU readout of RC6 can race against runtime PM transitions, and b) there are other reasons than being runtime suspended which can cause intel_runtime_pm_get_if_in_use to fail. Therefore when estimating RC6 the code needs to assert we are indeed in suspended state, and if not, the best we can do is return the last known RC6 value. Without this check we can calculate the estimated value based on un- initialized or inappropriate internal state, which can result in over- estimation, or in any case incorrect value being returned. v2: * Re-arrange the code a bit to avoid second unlock and return branch. (Chris Wilson) v3: * Insert some strategic blank lines and improve commit msg.
