2020-06-25net: phy: mscc: avoid skcipher API for single block AES encryptionArd Biesheuvel2-33/+10
The skcipher API dynamically instantiates the transformation object on request that implements the requested algorithm optimally on the given platform. This notion of optimality only matters for cases like bulk network or disk encryption, where performance can be a bottleneck, or in cases where the algorithm itself is not known at compile time. In the mscc case, we are dealing with AES encryption of a single block, and so neither concern applies, and we are better off using the AES library interface, which is lightweight and safe for this kind of use. Note that the scatterlist API does not permit references to buffers that are located on the stack, so the existing code is incorrect in any case, but avoiding the skcipher and scatterlist APIs entirely is the most straight-forward approach to fixing this.

2020-06-24net: bcmgenet: use hardware padding of runt framesDoug Berger1-5/+3
When commit 474ea9cafc45 ("net: bcmgenet: correctly pad short packets") added the call to skb_padto() it should have been located before the nr_frags parameter was read since that value could be changed when padding packets with lengths between 55 and 59 bytes (inclusive). The use of a stale nr_frags value can cause corruption of the pad data when tx-scatter-gather is enabled. This corruption of the pad can cause invalid checksum computation when hardware offload of tx-checksum is also enabled. Since the original reason for the padding was corrected by commit 7dd399130efb ("net: bcmgenet: fix skb_len in bcmgenet_xmit_single()") we can remove the software padding all together and make use of hardware padding of short frames as long as the hardware also always appends the FCS value to the frame.

This patch adds support for PHC and timestamping operations for the MSCC PHY. PTP 1-step and 2-step modes are supported, over Ethernet and UDP. To get and set the PHC time, a GPIO has to be used and changes are only retrieved or committed when on a rising edge. The same GPIO is shared by all PHYs, so the granularity of the lock protecting it has to be different from the ones protecting the 1588 registers (the VSC8584 PHY has 2 1588 blocks, and a single load/save pin).

2020-06-24net: phy: mscc: 1588 block initializationQuentin Schulz5-2/+1552
This patch adds the first parts of the 1588 support in the MSCC PHY, with registers definition and the 1588 block initialization. Those PHYs are distributed in hardware packages containing multiple times the PHY. The VSC8584 for example is composed of 4 PHYs. With hardware packages, parts of the logic is usually common and one of the PHY has to be used for some parts of the initialization. Following this logic, the 1588 blocks of those PHYs are shared between two PHYs and accessing the registers has to be done using the "base" PHY of the group. This is handled thanks to helpers in the PTP code (and locks). We also need the MDIO bus lock while performing a single read or write to the 1588 registers as the read/write are composed of multiple MDIO transactions (and we don't want other threads updating the page).

2020-06-23net: phy: Allow mdio buses to auto-probe c45 devicesJeremy Linton1-2/+16
The mdiobus_scan logic is currently hardcoded to only work with c22 devices. This works fairly well in most cases, but its possible that a c45 device doesn't respond despite being a standard phy. If the parent hardware is capable, it makes sense to scan for c22 devices before falling back to c45. As we want this to reflect the capabilities of the STA, lets add a field to the mii_bus structure to represent the capability. That way devices can opt into the extended scanning. Existing users should continue to default to c22 only scanning as long as they are zero'ing the structure before use.

With the support of generic PM callbacks, drivers no longer need to use legacy .suspend() and .resume() in which they had to maintain PCI states changes and device's power state themselves. Legacy PM involves usage of PCI helper functions like pci_enable_wake() which is no longer recommended. Compile-tested only.

With the support of generic PM callbacks, drivers no longer need to use legacy .suspend() and .resume() in which they had to maintain PCI states changes and device's power state themselves. Earlier, .suspend() and .resume() were invoking pci_disable_device() and pci_enable_device() respectively to manage the device's power state. driver also invoked pci_save/restore_state() and pci_set_power_sitate(). With generic PM, it is no longer needed. The driver is expected to just implement driver-specific operations and leave power transitions to PCI core. Compile-tested only.

With stable support of generic PM callbacks, drivers no longer need to use legacy .suspend() and .resume() in which they had to maintain PCI states changes and device's power state themselves. Earlier, .resume() was invoking pci_enable_device(). Drivers should not call PCI legacy helper functions, hence, it was removed. This should not change the behavior of the device as this function is called by PCI core if somehow pm_ops is not able to bind with the driver, else, required tasks are managed by the core itself.

With legacy PM hooks, it was the responsibility of a driver to manage PCI states and also the device's power state. The generic approach is to let the PCI core handle the work. The legacy suspend() and resume() were making use of pci_read/write_config_dword() to enable/disable wol. Driver editing configuration registers of a device is not recommended. Thus replace them all with device_wakeup_enable/disable(). Compile-tested only. Signed-off-by: Vaibhav Gupta <vaibhavgupta40@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-06-23amd-xgbe: Convert to generic power managementVaibhav Gupta1-10/+9
Use dev_pm_ops structure to call generic suspend() and resume() callbacks. Drivers should avoid saving device register and/or change power states using PCI helper functions. With the generic approach, all these are handled by PCI core. Compile-tested only. Signed-off-by: Vaibhav Gupta <vaibhavgupta40@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
