2018-03-14drm/amdgpu: explicit give BO type to amdgpu_bo_createChristian König

2018-03-14IB/mlx5: Maintain a single emergency pageIlya Lesokhin
The mlx5 driver needs to be able to issue invalidation to ODP MRs even if it cannot allocate memory. To this end it preallocates emergency pages to use when the situation arises. This flow should be extremely rare enough, that we don't need to worry about contention and therefore a single emergency page is good enough.

2018-03-14RDMA/core: Do not use invalid destination in determining port reuseTatyana Nikolova
cma_port_is_unique() allows local port reuse if the quad (source address and port, destination address and port) for this connection is unique. However, if the destination info is zero or unspecified, it can't make a correct decision but still allows port reuse. For example, sometimes rdma_bind_addr() is called with unspecified destination and reusing the port can lead to creating a connection with a duplicate quad, after the destination is resolved. The issue manifests when MPI scale-up tests hang after the duplicate quad is used. Set the destination address family and add checks for zero destination address and port to prevent source port reuse based on invalid destination.

2018-03-14dm mpath: fix passing integrity dataSteffen Maier
After v4.12 commit e2460f2a4bc7 ("dm: mark targets that pass integrity data"), dm-multipath, e.g. on DIF+DIX SCSI disk paths, does not support block integrity any more. So add it to the whitelist. This is also a pre-requisite to use block integrity with other dm layer(s) on top of multipath, such as kpartx partitions (dm-linear) or LVM. Also, bump target version to reflect this fix.

2018-03-14drm/amdgpu: refactoring mailbox to fix TDR handshake bugs(v2)Monk Liu
this patch actually refactor mailbox implmentations, and all below changes are needed together to fix all those mailbox handshake issues exposured by heavey TDR test. 1)refactor all mailbox functions based on byte accessing for mb_control reason is to avoid touching non-related bits when writing trn/rcv part of mailbox_control, this way some incorrect INTR sent to hypervisor side could be avoided, and it fixes couple handshake bug. 2)trans_msg function re-impled: put a invalid logic before transmitting message to make sure the ACK bit is in a clear status, otherwise there is chance that ACK asserted already before transmitting message and lead to fake ACK polling. (hypervisor side have some tricks to workaround ACK bit being corrupted by VF FLR which hase an side effects that may make guest side ACK bit asserted wrongly), and clear TRANS_MSG words after message transferred. 3)for mailbox_flr_work, it is also re-worked: it takes the mutex lock first if invoked, to block gpu recover's participate too early while hypervisor side is doing VF FLR. (hypervisor sends FLR_NOTIFY to guest before doing VF FLR and sentds FLR_COMPLETE after VF FLR done, and the FLR_NOTIFY will trigger interrupt to guest which lead to mailbox_flr_work being invoked) This can avoid the issue that mailbox trans msg being cleared by its VF FLR. 4)for mailbox_rcv_irq IRQ routine, it should only peek msg and schedule mailbox_flr_work, instead of ACK to hypervisor itself, because FLR_NOTIFY msg sent from hypervisor side doesn't need VF's ACK (this is because VF's ACK would lead to hypervisor clear its trans_valid/msg, and this would cause handshake bug if trans_valid/msg is cleared not due to correct VF ACK but from a wrong VF ACK like this "FLR_NOTIFY" one) This fixed handshake bug that sometimes GUEST always couldn't receive "READY_TO_ACCESS_GPU" msg from hypervisor. 5)seperate polling time limite accordingly: POLL ACK cost no more than 500ms POLL MSG cost no more than 12000ms POLL FLR finish cost no more than 500ms 6) we still need to set adev into in_gpu_reset mode after we received FLR_NOTIFY from host side, this can prevent innocent app wrongly succesed to open amdgpu dri device. FLR_NOFITY is received due to an IDLE hang detected from hypervisor side which indicating GPU is already die in this VF. v2: use MACRO as the offset of mailbox_control register don't test if NOTIFY_CMPL event in rcv_msg since it won't recieve that message anymore Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Pixel Ding <Pixel.Ding@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2018-03-14i40e: restore TCPv4 input set when re-enabling ATRJacob Keller
When we re-enable ATR we need to restore the input set for TCPv4 filters, in order for ATR to function correctly. We already do this for the normal case of re-enabling ATR when disabling ntuple support. However, when re-enabling ATR after the last TCPv4 filter is removed (but when ntuple support is still active), we did not restore the TCPv4 filter input set. This can cause problems if the TCPv4 filters from FDir had changed the input set, as ATR will no longer behave as expected. When clearing the ATR auto-disable flag, make sure we restore the TCPv4 input set to avoid this.

2018-03-14i40e: fix for wrong partition id calculation on OCP mezz cardsMariusz Stachura
This patch overwrites number of ports for X722 devices with support for OCP PHY mezzanine. The old method with checking if port is disabled in the PRTGEN_CNF register cannot be used in this case. When the OCP is removed, ports were seen as disabled, which resulted in wrong calculation of partition id, that caused WoL to be disabled on certain ports.

2018-03-14i40e: Fix permission check for VF MAC filtersFilip Sadowski
When VF requests adding of MAC filters the checking is done against number of already present MAC filters not adding them at the same time. It makes it possible to add a bunch of filters at once possibly exceeding acceptable limit of I40E_VC_MAX_MAC_ADDR_PER_VF filters. This happens because when checking vf->num_mac, we do not check how many filters are being requested at once. Modify the check function to ensure that it knows how many filters are being requested. This allows the check to ensure that the total number of filters in a single request does not cause us to go over the limit. Additionally, move the check to within the lock to ensure that the vf->num_mac is checked while holding the lock to maintain consistency. We could have simply moved the call to i40e_vf_check_permission to within the loop, but this could cause a request to be non-atomic, and add some but not all the addresses, while reporting an error code. We want to avoid this behavior so that users are not confused about which filters have or have not been added.

2018-03-14i40e: Cleanup i40e_vlan_rx_registerJacob Keller
We used to use the function i40e_vlan_rx_register as a way to hook into the now defunct .ndo_vlan_rx_register netdev hook. This was removed but we kept the function around because we still used it internally to control enabling or disabling of VLAN stripping. As pointed out in upstream review, VLAN stripping is only used in a single location and the previous function is quite small, just inline it into i40e_restore_vlan() rather than carrying the function separately.

When the VF driver is loaded on host and virsh is trying to attach it to the VM and set a MAC address, it ends with a race condition between i40e_reset_vf and i40e_ndo_set_vf_mac functions.

2018-03-14RDMAVT: Fix synchronization around percpu_refTejun Heo
rvt_mregion uses percpu_ref for reference counting and RCU to protect accesses from lkey_table. When a rvt_mregion needs to be freed, it first gets unregistered from lkey_table and then rvt_check_refs() is called to wait for in-flight usages before the rvt_mregion is freed. rvt_check_refs() seems to have a couple issues. * It has a fast exit path which tests percpu_ref_is_zero(). However, a percpu_ref reading zero doesn't mean that the object can be released. In fact, the ->release() callback might not even have started executing yet. Proceeding with freeing can lead to use-after-free. * lkey_table is RCU protected but there is no RCU grace period in the free path. percpu_ref uses RCU internally but it's sched-RCU whose grace periods are different from regular RCU. Also, it generally isn't a good idea to depend on internal behaviors like this. To address the above issues, this patch removes the fast exit and adds an explicit synchronize_rcu().

2018-03-14firmware: enable to split firmware_class into separate target filesLuis R. Rodriguez
The firmware loader code has grown quite a bit over the years. The practice of stuffing everything we need into one file makes the code hard to follow. In order to split the firmware loader code into different components we must pick a module name and a first object target file. We must keep the firmware_class name to remain compatible with scripts which have been relying on the sysfs loader path for years, so the old module name stays. We can however rename the C file without affecting the module name. The firmware_class used to represent the idea that the code was a simple sysfs firmware loader, provided by the struct class firmware_class. The sysfs firmware loader used to be the default, today its only the fallback mechanism. This only renames the target code then to make emphasis of what the code does these days. With this change new features can also use a new object files. Signed-off-by: Luis R. Rodriguez <mcgrof@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
