2020-03-30Merge branch 'Devlink-health-auto-attributes-refactor'David S. Miller
Eran Ben Elisha says: ==================== Devlink health auto attributes refactor This patchset refactors the auto-recover health reporter flag to be explicitly set by the devlink core. In addition, add another flag to control auto-dump attribute, also to be explicitly set by the devlink core. For that, patch 0001 changes the auto-recover default value of netdevsim dummy reporter. After reporter registration, both flags can be altered be administrator only. Changes since v1: - Change default behaviour of netdevsim dummy reporter - Move initialization of DEVLINK_ATTR_HEALTH_REPORTER_AUTO_DUMP ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-30devlink: Add auto dump flag to health reporterEran Ben Elisha
On low memory system, run time dumps can consume too much memory. Add administrator ability to disable auto dumps per reporter as part of the error flow handle routine. This attribute is not relevant while executing DEVLINK_CMD_HEALTH_REPORTER_DUMP_GET. By default, auto dump is activated for any reporter that has a dump method, as part of the reporter registration to devlink.

2020-03-30devlink: Implicitly set auto recover flag when registering health reporterEran Ben Elisha
When health reporter is registered to devlink, devlink will implicitly set auto recover if and only if the reporter has a recover method. No reason to explicitly get the auto recover flag from the driver. Remove this flag from all drivers that called devlink_health_reporter_create. All existing health reporters set auto recovery to true if they have a recover method. Yet, administrator can unset auto recover via netlink command as prior to this patch.

2020-03-30ptp: Avoid deadlocks in the programmable pin code.Richard Cochran
The PTP Hardware Clock (PHC) subsystem offers an API for configuring programmable pins. User space sets or gets the settings using ioctls, and drivers verify dialed settings via a callback. Drivers may also query pin settings by calling the ptp_find_pin() method. Although the core subsystem protects concurrent access to the pin settings, the implementation places illogical restrictions on how drivers may call ptp_find_pin(). When enabling an auxiliary function via the .enable(on=1) callback, drivers may invoke the pin finding method, but when disabling with .enable(on=0) drivers are not permitted to do so. With the exception of the mv88e6xxx, all of the PHC drivers do respect this restriction, but still the locking pattern is both confusing and unnecessary. This patch changes the locking implementation to allow PHC drivers to freely call ptp_find_pin() from their .enable() and .verify() callbacks.

In this case, the port capabilities, including speed ability, autoneg ability, media type, may be incorrect. Then get/set link ksetting may fail.

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.

2020-03-30Crypto: chelsio - Fixes a hang issue during driver registrationAyush Sawal
This issue occurs only when multiadapters are present. Hang happens because assign_chcr_device returns u_ctx pointer of adapter which is not yet initialized as for this adapter cxgb_up is not been called yet. 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>
