Jeff Kirsher says: ==================== Intel Wired LAN Driver Fixes 2019-03-26 This series contains updates to igb, ixgbe, i40e and fm10k. Jake fixes an issue with PTP in i40e where a previous commit resulted in a regression where the driver would interpret small negative adjustments as large positive additions, resulting in incorrect behavior. Arvind Sankar fixes an issue in igb where a previous commit would cause a warning in the PCI pm core and resulted in pci_pm_runtime_suspend would not call pci_save_state or pci_finish_runtime_suspend. Ivan Vecera fixes MDIO bus registration with ixgbe, where the driver was ignoring errors returned when registering and would leave the pointer in a NULL state which triggered a BUG when un-registering. Stefan Assmann fixes the check for Wake-On-LAN for i40e, which only supports magic packet. Yue Haibing fixes a potential NULL pointer de-reference in fm10k by adding a simple check if the value is NULL. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2019-03-27vrf: prevent adding upper devicesSabrina Dubroca1-0/+1
VRF devices don't work with upper devices. Currently, it's possible to add a VRF device to a bridge or team, and to create macvlan, macsec, or ipvlan devices on top of a VRF (bond and vlan are prevented respectively by the lack of an ndo_set_mac_address op and the NETIF_F_VLAN_CHALLENGED feature flag). Fix this by setting the IFF_NO_RX_HANDLER flag (introduced in commit f5426250a6ec ("net: introduce IFF_NO_RX_HANDLER")).

2019-03-27thunderx: eliminate extra calls to put_page() for pages held for recyclingDean Nelson1-4/+3
For the non-XDP case, commit 773225388dae15e72790 ("net: thunderx: Optimize page recycling for XDP") added code to nicvf_free_rbdr() that, when releasing the additional receive buffer page reference held for recycling, repeatedly calls put_page() until the page's _refcount goes to zero. Which results in the page being freed. This is not okay if the page's _refcount was greater than 1 (in the non-XDP case), because nicvf_free_rbdr() should not be subtracting more than what nicvf_alloc_page() had previously added to the page's _refcount, which was only 1 (in the non-XDP case). This can arise if a received packet is still being processed and the receive buffer (i.e., skb->head) has not yet been freed via skb_free_head() when nicvf_free_rbdr() is spinning through the aforementioned put_page() loop. If this should occur, when the received packet finishes processing and skb_free_head() is called, various problems can ensue. Exactly what, depends on whether the page has already been reallocated or not, anything from "BUG: Bad page state ... ", to "Unable to handle kernel NULL pointer dereference ..." or "Unable to handle kernel paging request...". So this patch changes nicvf_free_rbdr() to only call put_page() once for pages held for recycling (in the non-XDP case).

This patch corrects two if-conditionals to allow for the recycling of non-XDP mode pages by only setting the page pointer to NULL when the page is not ready for recycling.

2019-03-27net: dsa: mv88e6xxx: fix few issues in mv88e6390x_port_set_cmodeHeiner Kallweit1-8/+16
This patches fixes few issues in mv88e6390x_port_set_cmode(). 1. When entering the function the old cmode may be 0, in this case mv88e6390x_serdes_get_lane() returns -ENODEV. As result we bail out and have no chance to set a new mode. Therefore deal properly with -ENODEV. 2. Once we have disabled power and irq, let's set the cached cmode to 0. This reflects the actual status and is cleaner if we bail out with an error in the following function calls. 3. The cached cmode is used by mv88e6390x_serdes_get_lane(), mv88e6390_serdes_power_lane() and mv88e6390_serdes_irq_enable(). Currently we set the cached mode to the new one at the very end of the function only, means until then we use the old one what may be wrong. 4. When calling mv88e6390_serdes_irq_enable() we use the lane value belonging to the old cmode. Get the lane belonging to the new cmode before calling this function. It's hard to provide a good "Fixes" tag because quite a few smaller changes have been done to the code in question recently.

2019-03-26igb: Fix WARN_ONCE on runtime suspendArvind Sankar2-49/+10
The runtime_suspend device callbacks are not supposed to save configuration state or change the power state. Commit fb29f76cc566 ("igb: Fix an issue that PME is not enabled during runtime suspend") changed the driver to not save configuration state during runtime suspend, however the driver callback still put the device into a low-power state. This causes a warning in the pci pm core and results in pci_pm_runtime_suspend not calling pci_save_state or pci_finish_runtime_suspend. Fix this by not changing the power state either, leaving that to pci pm core, and make the same change for suspend callback as well. Also move a couple of defines into the appropriate header file instead of inline in the .c file.

Commit 0ac30ce43323 ("i40e: fix up 32 bit timespec references", 2017-07-26) claims to be cleaning up references to 32-bit timespecs. The actual contents of the commit make no sense, as it converts a call to timespec64_add into timespec64_add_ns. This would seem ok, if (a) the change was documented in the commit message, and (b) timespec64_add_ns supported negative numbers. timespec64_add_ns doesn't work with signed deltas, because the implementation is based around iter_div_u64_rem. This change resulted in a regression where i40e_ptp_adjtime would interpret small negative adjustments as large positive additions, resulting in incorrect behavior. This commit doesn't appear to fix anything, is not well explained, and introduces a bug, so lets just revert it.

This patch implements accessors for the QCA8337 MDIO access through the MDIO_MASTER register, which makes it possible to access the PHYs on slave-bus through the switch. In cases where the switch ports are already mapped via external "phy-phandles", the internal mdio-bus is disabled in order to prevent a duplicated discovery and enumeration of the same PHYs.

This is because the DSA subsystem will create a slave mdio-bus not knowing that the qca8k_phy_(read|write) accessors operate on the external mdio-bus. So the same "bus" gets effectively duplicated.

So far we effectively clear the BMCR register. Some PHY's can deal with this (e.g. because they reset BMCR to a default as part of a soft-reset) whilst on others this causes issues because e.g. the autoneg bit is cleared. Marvell is an example, see also thread [0]. So let's be a little bit more gentle and leave all bits we're not interested in as-is.

2019-03-25Revert "parport: daisy: use new parport device model"Linus Torvalds3-41/+3
This reverts commit 1aec4211204d9463d1fd209eb50453de16254599. Steven Rostedt reports that it causes a hang at bootup and bisected it to this commit. The troigger is apparently a module alias for "parport_lowlevel" that points to "parport_pc", which causes a hang with modprobe -q -- parport_lowlevel blocking forever with a backtrace like this: wait_for_completion_killable+0x1c/0x28 call_usermodehelper_exec+0xa7/0x108 __request_module+0x351/0x3d8 get_lowlevel_driver+0x28/0x41 [parport] __parport_register_driver+0x39/0x1f4 [parport] daisy_drv_init+0x31/0x4f [parport] parport_bus_init+0x5d/0x7b [parport] parport_default_proc_register+0x26/0x1000 [parport] do_one_initcall+0xc2/0x1e0 do_init_module+0x50/0x1d4 load_module+0x1c2e/0x21b3 sys_init_module+0xef/0x117 Supid says: "Due to the new device model daisy driver will now try to find the parallel ports while trying to register its driver so that it can bind with them. Now, since daisy driver is loaded while parport bus is initialising the list of parport is still empty and it tries to load the lowlevel driver, which has an alias set to parport_pc, now causes a deadlock" But I don't think the daisy driver should be loaded by the parport initialization in the first place, so let's revert the whole change. If the daisy driver can just initialize separately on its own (like a driver should), instead of hooking into the parport init sequence directly, this issue probably would go away.

2019-03-23r8169: fix cable re-plugging issueHeiner Kallweit1-1/+1
Bartek reported that after few cable unplug/replug cycles suddenly replug isn't detected any longer. His system uses a RTL8106, I wasn't able to reproduce the issue with RTL8168g. According to his bisect the referenced commit caused the regression. As Realtek doesn't release datasheets or errata it's hard to say what's the actual root cause, but this change was reported to fix the issue.
