Huazhong Tan says: ==================== net: hns3: fixes for -net This patchset includes some bugfixes for the HNS3 ethernet driver. [patch 1] removes flag WQ_MEM_RECLAIM flag when allocating WE, since it will cause a warning when the reset task flushes a IB's WQ. [patch 2] adds a new DESC_TYPE_FRAGLIST_SKB type to handle the linear data of the fraglist SKB, since it is different with the frag data. [patch 3] adds different handings for RSS configuration when load or reset. [patch 4] fixes a link ksetting issue. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-30net: hns3: fix set and get link ksettings issueGuangbin Huang
When device is not open, the service task which update the port information per second is not running. In this case, the port capabilities, including speed ability, autoneg ability, media type, may be incorrect. Then get/set link ksetting may fail. This patch fixes it by updating the port information before getting/ setting link ksettings when device is not open, and start timer task immediately by setting delay time to 0 when device opens.

2020-03-30net: fix fraglist segmentation reference count leakFlorian Westphal
Xin Long says: On udp rx path udp_rcv_segment() may do segment where the frag skbs will get the header copied from the head skb in skb_segment_list() by calling __copy_skb_header(), which could overwrite the frag skbs' extensions by __skb_ext_copy() and cause a leak. This issue was found after loading esp_offload where a sec path ext is set in the skb. Fix this by discarding head state of the fraglist skb before replacing its contents.

This issue occurs only when multiadapters are present.

The last_dev pointer is used to determine u_ctx pointer and it is initialized two times in chcr_uld_add in chcr_dev_add respectively. The fix here is don't initialize the last_dev pointer during chcr_uld_add. Only assign to value to it when the adapter's initialization is completed i.e in chcr_dev_add.

2020-03-30x86/xen: Make the secondary CPU idle tasks reliableMiroslav Benes
The unwinder reports the secondary CPU idle tasks' stack on XEN PV as unreliable, which affects at least live patching. cpu_initialize_context() sets up the context of the CPU through VCPUOP_initialise hypercall. After it is woken up, the idle task starts in cpu_bringup_and_idle() function and its stack starts at the offset right below pt_regs. The unwinder correctly detects the end of stack there but it is confused by NULL return address in the last frame. Introduce a wrapper in assembly, which just calls cpu_bringup_and_idle(). The return address is thus pushed on the stack and the wrapper contains the annotation hint for the unwinder regarding the stack state.

2020-03-30x86/xen: Make the boot CPU idle task reliableMiroslav Benes
The unwinder reports the boot CPU idle task's stack on XEN PV as unreliable, which affects at least live patching. There are two reasons for this. First, the task does not follow the x86 convention that its stack starts at the offset right below saved pt_regs. It allows the unwinder to easily detect the end of the stack and verify it. Second, startup_xen() function does not store the return address before jumping to xen_start_kernel() which confuses the unwinder. Amend both issues by moving the starting point of initial stack in startup_xen() and storing the return address before the jump, which is exactly what call instruction does.

2020-03-30PCI: Add support for root bus sizingIvan Kokshaysky
In certain cases we should be able to enumerate IO and MEM ranges of all PCI devices installed in the system, and then set respective host bridge apertures basing on calculated size and alignment. Particularly when firmware is broken and fails to assign bridge windows properly, like on Alpha UP1500 platform. Actually, almost everything is already in place, and required changes are minimal: - add "size_windows" flag to struct pci_host_bridge: when set, it instructs __pci_bus_size_bridges() to continue with the root bus; - in the __pci_bus_size_bridges() path: add checks for bus->self, as it can legitimately be null for the root bus.

2020-03-30PCI: Use ioremap(), not phys_to_virt() for platform ROMMikel Rychliski
On some EFI systems, the video BIOS is provided by the EFI firmware. The boot stub code stores the physical address of the ROM image in pdev->rom. Currently we attempt to access this pointer using phys_to_virt(), which doesn't work with CONFIG_HIGHMEM. On these systems, attempting to load the radeon module on a x86_32 kernel can result in the following: BUG: unable to handle page fault for address: 3e8ed03c #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP CPU: 0 PID: 317 Comm: systemd-udevd Not tainted 5.6.0-rc3-next-20200228 #2 Hardware name: Apple Computer, Inc.

Instead of calling the helper function pci_platform_rom() which uses phys_to_virt(), call ioremap() directly on the pdev->rom. radeon_read_platform_bios() previously directly accessed an __iomem pointer. Avoid this by calling memcpy_fromio() instead of kmemdup(). pci_platform_rom() now has no remaining callers, so remove it.

2020-03-30gfs2: Fix oversight in gfs2_ail1_flushBob Peterson
Ordinarily, function gfs2_ail1_start_one issues a write request for one item on the ail1 list, then returns -EBUSY. This makes the caller, gfs2_ail1_flush, loop around and start another. However, it was not clearing the -EBUSY return code each time through the loop. So on rare occasions, like when the wbc runs out of nr_to_write, it remained set to -EBUSY, which triggered an error and withdraw. This patch sets the return code to 0 each time through the restart loop so this won't happen anymore. Signed-off-by: Bob Peterson <rpeterso@redhat.com>

Similarly to other ACPI tables, data provided by BIOS may not describe it correctly, thus overriding is required. ACPI override mechanism checks for unknown signature before proceeding.
