2017-08-22iommu/mediatek: Add mt2712 IOMMU supportYong Wu
The M4U IP blocks in mt2712 is MTK's generation2 M4U which use the ARM Short-descriptor like mt8173, and most of the HW registers are the same. The difference is that there are 2 M4U HWs in mt2712 while there's only one in mt8173. The purpose of 2 M4U HWs is for balance the bandwidth. Normally if there are 2 M4U HWs, there should be 2 iommu domains, each M4U has a iommu domain. Signed-off-by: Yong Wu <yong.wu@mediatek.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
2017-08-22iommu/mediatek: Move MTK_M4U_TO_LARB/PORT into mtk_iommu.cYong Wu
The definition of MTK_M4U_TO_LARB and MTK_M4U_TO_PORT are shared by all the gen2 M4U HWs. Thus, Move them out from mt8173-larb-port.h, and put them into the c file.

2017-08-15iommu: Fix wrong freeing of iommu_device->devJoerg Roedel
The struct iommu_device has a 'struct device' embedded into it, not as a pointer, but the whole struct. In the conversion of the iommu drivers to use struct iommu_device it was forgotten that the relase function for that struct device simply calls kfree() on the pointer. This frees memory that was never allocated and causes memory corruption. To fix this issue, use a pointer to struct device instead of embedding the whole struct. This needs some updates in the iommu sysfs code as well as the Intel VT-d and AMD IOMMU driver. Reported-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Fixes: 39ab9555c241 ('iommu: Add sysfs bindings for struct iommu_device') Cc: stable@vger.kernel.org # >= v4.11 Signed-off-by: Joerg Roedel <jroedel@suse.de>

Commit c54451a "iommu/arm-smmu: Fix the error path in arm_smmu_add_device" removed fwspec assignment in legacy_binding path as redundant which is wrong. It needs to be updated after fwspec initialisation in arm_smmu_register_legacy_master() as it is dereferenced later. Without this there is a NULL-pointer dereference panic during boot on some hosts.

2017-07-26iommu/amd: Fix schedule-while-atomic BUG in initialization codeJoerg Roedel
The register_syscore_ops() function takes a mutex and might sleep. In the IOMMU initialization code it is invoked during irq-remapping setup already, where irqs are disabled. This causes a schedule-while-atomic bug: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:747 in_atomic(): 0, irqs_disabled(): 1, pid: 1, name: swapper/0 no locks held by swapper/0/1. irq event stamp: 304 hardirqs last enabled at (303): [<ffffffff818a87b6>] _raw_spin_unlock_irqrestore+0x36/0x60 hardirqs last disabled at (304): [<ffffffff8235d440>] enable_IR_x2apic+0x79/0x196 softirqs last enabled at (36): [<ffffffff818ae75f>] __do_softirq+0x35f/0x4ec softirqs last disabled at (31): [<ffffffff810c1955>] irq_exit+0x105/0x120 CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.13.0-rc2.1.el7a.test.x86_64.debug #1 Hardware name: PowerEdge C6145 /040N24, BIOS 3.5.0 10/28/2014 Call Trace: dump_stack+0x85/0xca ___might_sleep+0x22a/0x260 __might_sleep+0x4a/0x80 __mutex_lock+0x58/0x960 ? iommu_completion_wait.part.17+0xb5/0x160 ? register_syscore_ops+0x1d/0x70 ? iommu_flush_all_caches+0x120/0x150 mutex_lock_nested+0x1b/0x20 register_syscore_ops+0x1d/0x70 state_next+0x119/0x910 iommu_go_to_state+0x29/0x30 amd_iommu_enable+0x13/0x23 Fix it by moving the register_syscore_ops() call to the next initialization step, which runs with irqs enabled.

2017-07-23xen/balloon: don't online new memory initiallyJuergen Gross
When setting up the Xenstore watch for the memory target size the new watch will fire at once. Don't try to reach the configured target size by onlining new memory in this case, as the current memory size will be smaller in almost all cases due to e.g. BIOS reserved pages. Onlining new memory will lead to more problems e.g. undesired conflicts with NVMe devices meant to be operated as block devices. Instead remember the difference between target size and current size when the watch fires for the first time and apply it to any further size changes, too. In order to avoid races between balloon.c and xen-balloon.c init calls do the xen-balloon.c initialization from balloon.c.

balance-alb mode used to have transmit dynamic load balancing feature enabled by default. However, transmit dynamic load balancing no longer works in balance-alb after commit 8b426dc54cf4 ("bonding: remove hardcoded value"). Both balance-tlb and balance-alb use the function bond_do_alb_xmit() to send packets. This function uses the parameter tlb_dynamic_lb. tlb_dynamic_lb used to have the default value of 1 for balance-alb, but now the value is set to 0 except in balance-tlb.

2017-07-20IB/mlx4: Fix CM REQ retries in paravirt modeHåkon Bugge
CM REQs cannot be successfully retried, because a new pv_cm_id is created for each request, without checking if one already exists. By checking if an id exists before creating one, the bug is fixed. This bug can be provoked by running an RDMA CM user-land application, but inserting a five seconds delay before the rdma_accept() call on the passive side. This delay is larger than the default CMA timeout, and triggers a retry from the active side. The retried REQ will use another pv_cm_id (the cm_id on the wire). This confuses the CM protocol and two REJs are sent from the passive side. Here is an excerpt from ibdump running without the patch: 3.285092 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 7.382711 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 7.382861 LID: 4 -> LID: 4 InfiniBand 290 CM: ConnectReject 7.387644 LID: 4 -> LID: 4 InfiniBand 290 CM: ConnectReject and here is the same with bug fix applied: 3.251010 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 7.349387 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 8.258443 LID: 4 -> LID: 4 SDP 290 CM: ConnectReply(SDP Hello) 8.259890 LID: 4 -> LID: 4 InfiniBand 290 CM: ReadyToUse Suggested-by: Venkat Venkatsubra <venkat.x.venkatsubra@oracle.com> Signed-off-by: Håkon Bugge <haakon.bugge@oracle.com> Reported-by: Wei Lin Guay <wei.lin.guay@oracle.com> Tested-by: Wei Lin Guay <wei.lin.guay@oracle.com> Reviewed-by: Yuval Shaia <yuval.shaia@oracle.com> Acked-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Doug Ledford <dledford@redhat.com>
2017-07-20IB/rdmavt: Setting of QP timeout can overflow jiffies computationKaike Wan
Current computation of qp->timeout_jiffies in rvt_modify_qp() will cause overflow due to the fact that the input to the function usecs_to_jiffies is only 32-bit ( unsigned int). Overflow will occur when attr->timeout is equal to or greater than 30. The consequence is unnecessarily excessive retry and thus degradation of the system performance. This patch fixes the problem by limiting the input to 5-bit and calling usecs_to_jiffies() before multiplying the scaling factor.

2017-07-20RDMA/bnxt_re: Fixed the max_rd_atomic support for initiator and destination QPEddie Wai
There's a couple of bugs in the support of max_rd_atomic and max_dest_rd_atomic. In the modify_qp, if the requested max_rd_atomic, which is the ORRQ size, is greater than what the chip can support, then we have to cap the request to chip max as we can't have the HW overflow the ORRQ. Capping the max_rd_atomic support internally is okay to do as the remaining read/atomic WRs will still be sitting in the SQ. However, for the max_dest_rd_atomic, the driver has to error out as this dictates the IRRQ size and we can't control what the remote side sends.
