2020-03-30alpha: Fix nautilus PCI setupIvan Kokshaysky
Example (hopefully reasonable) of the new "size_windows" flag usage. Fixes accidental breakage caused by f75b99d5a77d ("PCI: Enforce bus address limits in resource allocation").

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>

2020-03-29net/mlx5: Use a separate work queue for fib event handlingMark Zhang
In VF lag mode when remove the bonding module without bring down the bond device first, we could potentially have circular dependency when we unload IB devices and also handle fib events: 1. The bond work starts first; 2. The "modprobe -rv bonding" process tries to release the bond device, with the "pernet_ops_rwsem" lock hold; 3. The bond work blocks in unregister_netdevice_notifier() and waits for the lock because fib event came right before; 4. The kernel fib module tries to free all the fib entries by broadcasting the "FIB_EVENT_NH_DEL" event; 5. Upon the fib event this lag_mp module holds the fib lock and queue a fib work. So: bond work -> modprobe task -> kernel fib module -> lag_mp -> bond work Today we either reload IB devices in roce lag in nic mode or either handle fib events in switchdev mode, but a new feature could change that we'll need to reload IB devices also in switchdev mode so this is a future proof fix as one may not notice this later.

2020-03-29ethtool: set coalescing parameters with COALESCE_SET requestMichal Kubecek
Implement COALESCE_SET netlink request to set coalescing parameters of a network device. These are traditionally set with ETHTOOL_SCOALESCE ioctl request. This commit adds only support for device coalescing parameters, not per queue coalescing parameters. Like the ioctl implementation, the generic ethtool code checks if only supported parameters are modified; if not, first offending attribute is reported using extack. v2: fix alignment (whitespace only) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

Implement COALESCE_GET request to get coalescing parameters of a network device. These are traditionally available via ETHTOOL_GCOALESCE ioctl request. This commit adds only support for device coalescing parameters, not per queue coalescing parameters.

2020-03-29ethtool: fix reference leak in ethnl_set_privflags()Michal Kubecek
Andrew noticed that some handlers for *_SET commands leak a netdev reference if required ethtool_ops callbacks do not exist. One of them is ethnl_set_privflags(), a simple reproducer would be e.g. ip link add veth1 type veth peer name veth2 ethtool --set-priv-flags veth1 foo on ip link del veth1 Make sure dev_put() is called when ethtool_ops check fails.

2020-03-29Merge branch 'ipv6-add-rpl-source-routing'David S. Miller
Alexander Aring says: ==================== net: ipv6: add rpl source routing This patch series will add handling for RPL source routing handling and insertion (implement as lwtunnel)! I did an example prototype implementation in rpld for using this implementation in non-storing mode: https://github.com/linux-wpan/rpld/tree/nonstoring_mode I will also present a talk at netdev about it: https://netdevconf.info/0x14/session.html?talk-extend-segment-routing-for-RPL In receive handling I add handling for IPIP encapsulation as RFC6554 describes it as possible. For reasons I didn't implemented it yet for generating such packets because I am not really sure how/when this should happen. So far I understand there exists a draft yet which describes the cases (inclusive a Hop-by-Hop option which we also not support yet). https://tools.ietf.org/html/draft-ietf-roll-useofrplinfo-35 This is just the beginning to start implementation everything for yet, step by step. It works for my use cases yet to have it running on a 6LOWPAN _only_ network. I have some patches for iproute2 as well. A sidenote: I check on local addresses if they are part of segment routes, this is just to avoid stupid settings. A use can add addresses afterwards what I cannot control anymore but then it's users fault to make such thing. The receive handling checks for this as well which is required by RFC6554, so the next hops or when it comes back should drop it anyway. To make this possible I added functionality to pass the net structure to the build_state of lwtunnel (I hope I caught all lwtunnels). Another sidenote: I set the headroom value to 0 as I figured out it will break on interfaces with IPv6 min mtu if set to non zero for tunnels on L3. - Alex changes since v3: - use parse_nested which isn't deprecated - Thanks David Ahern - change to return -1 instead errno in exthdr handling to unify error code - change function name from ipv6_rpl_srh_decompress_size to ipv6_rpl_srh_size changes since v2: - add additional segdata length in lwtunnel build_state - fix build_state patch by not catching one inline noop function if LWTUNNEL is disabled Alexander Aring (5): include: uapi: linux: add rpl sr header definition addrconf: add functionality to check on rpl requirements net: ipv6: add support for rpl sr exthdr net: add net available in build_state net: ipv6: add rpl sr tunnel ==================== Signed-off-by: David S.

2020-03-29net: ipv6: add rpl sr tunnelAlexander Aring
This patch adds functionality to configure routes for RPL source routing functionality. There is no IPIP functionality yet implemented which can be added later when the cases when to use IPv6 encapuslation comes more clear.

2020-03-29net: add net available in build_stateAlexander Aring
The build_state callback of lwtunnel doesn't contain the net namespace structure yet. This patch will add it so we can check on specific address configuration at creation time of rpl source routes.

2020-03-29net: ipv6: add support for rpl sr exthdrAlexander Aring
This patch adds rpl source routing receive handling. Everything works only if sysconf "rpl_seg_enabled" and source routing is enabled. Mostly the same behaviour as IPv6 segmentation routing. To handle compression and uncompression a rpl.c file is created which contains the necessary functionality. The receive handling will also care about IPv6 encapsulated so far it's specified as possible nexthdr in RFC 6554. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S.

2020-03-29addrconf: add functionality to check on rpl requirementsAlexander Aring
This patch adds a functionality to addrconf to check on a specific RPL address configuration. According to RFC 6554: To detect loops in the SRH, a router MUST determine if the SRH includes multiple addresses assigned to any interface on that router. If such addresses appear more than once and are separated by at least one address not assigned to that router. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S.

2020-03-29include: uapi: linux: add rpl sr header definitionAlexander Aring
This patch adds a uapi header for rpl struct definition. The segments data can be accessed over rpl_segaddr or rpl_segdata macros. In case of compri and compre is zero the segment data is not compressed and can be accessed by rpl_segaddr. In the other case the compressed data can be accessed by rpl_segdata and interpreted as byte array. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S.
