2017-07-07tpm: fix a kernel memory leak in tpm-sysfs.cJarkko Sakkinen1-1/+2
While cleaning up sysfs callback that prints EK we discovered a kernel memory leak. This commit fixes the issue by zeroing the buffer used for TPM command/response. The leak happen when we use either tpm_vtpm_proxy, tpm_ibmvtpm or xen-tpmfront.

2017-07-07tpm: Issue a TPM2_Shutdown for TPM2 devices.Josh Zimmerman2-0/+37
If a TPM2 loses power without a TPM2_Shutdown command being issued (a "disorderly reboot"), it may lose some state that has yet to be persisted to NVRam, and will increment the DA counter. After the DA counter gets sufficiently large, the TPM will lock the user out. NOTE: This only changes behavior on TPM2 devices. Since TPM1 uses sysfs, and sysfs relies on implicit locking on chip->ops, it is not safe to allow this code to run in TPM1, or to add sysfs support to TPM2, until that locking is made explicit.

2017-07-05Cavium CNN55XX: fix broken default Kconfig entryLinus Torvalds1-1/+0
Every developer always thinks that _their_ code is so special and magical that it should be enabled by default. And most of them are completely and utterly wrong. That's definitely the case when you write a specialty driver for a very unsual "security processor". It does *not* get to mark itself as "default m". If you solve world hunger, and make a driver that cures people of cancer, by all means enable it by default. But afaik, the Cavium CNN55XX does neither.

2017-07-05net: phy: dp83867: add workaround for incorrect RX_CTRL pin strapMurali Karicheri1-0/+11
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017, advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not supported (see note below Table 5 (4-Level Strap Pins)). There are some boards which have the pin strapped this way and need software workaround suggested by the data manual. Bit[7] of Configuration Register 4 (address 0x0031) must be cleared to 0. This ensures proper operation of the PHY. Implement driver support for device-tree property meant to advertise the wrong strapping.

It further advises that if a board has this pin strapped in mode 1 and mode 2, then to ensure proper operation of the PHY, a software workaround must be implemented. Since it is not possible to detect in software if RX_DV/RX_CTRL pin is incorrectly strapped, add a device-tree property for the board to advertise this and allow corrective action in software.

2017-07-05nfp: default to chained metadata prepend formatJakub Kicinski1-1/+8
ABI 4.x introduced the chained metadata format and made it the only one possible. There are cases, however, where the old format is preferred - mostly to make interoperation with VFs using ABI 3.x easier for the datapath. In ABI 5.x we allowed for more flexibility by selecting the metadata format based on capabilities. The default was left to non-chained. In case of fallback traffic, there is no capability telling the driver there may be chained metadata. With a very stripped- -down FW the default old metadata format would be selected making the driver drop all fallback traffic. This patch changes the default selection in the driver. It should not hurt with old firmwares, because if they don't advertise RSS they will not produce metadata anyway. New firmwares advertising ABI 5.x, however, can depend on the driver defaulting to chained format.

2017-07-05nfp: remove legacy MAC address lookupJakub Kicinski4-34/+8
The legacy MAC address lookup doesn't work well with breakout cables. We are probably better off picking random addresses than the wrong ones in the theoretical scenario where management FW didn't tell us what the port config is.

2017-07-05nfp: improve order of interfaces in breakout modeJakub Kicinski3-14/+12
For historical reasons we enumerate the vNICs in order. This means that if user configures breakout on a multiport card, the first interface of the second port will have its MAC address changed. What's worse, when moved from static information (HWInfo) to using management FW (NSP), more features started depending on the port ids. Right now in case of breakout first subport of the second port and second subport of the first port will have their link info swapped. Revise the ordering scheme so that first subport maintains its address. Side effect of this change is that we will use base lane ids in devlink (i.e. 40G ports will be 4 ids apart), e.g.: pci/0000:04:00.0/0: type eth netdev p6p1 pci/0000:04:00.0/4: type eth netdev p6p2 Note that behaviour of phys_port_id is not changed since there is a separate id number for the subport there.
