2020-07-27of: property: Add device link support for pinctrl-0 through pinctrl-8Saravana Kannan
Add support for pinctrl-0 through pinctrl-8 explicitly instead of trying to add support for pinctrl-%d properties. Of all the pinctrl-* properties in dts files (20322), only 47% (9531) are pinctrl-%d properties. Of all the pinctrl-%d properties, 99.5% (9486) are made up of pinctrl-[0-2]. 'pinctrl-8' is the current maximum found in dts files. Trying to parse all pinctrl-* properties and checking for pinctrl-%d is unnecessarily complicated. So, just add support for pinctrl-[0-8] for now. In the unlikely event we ever exceed pinctrl-8, we can come back and improve this.

2020-07-27tools, bpftool: Skip type probe if name is not foundQuentin Monnet
For probing program and map types, bpftool loops on type values and uses the relevant type name in prog_type_name[] or map_type_name[]. To ensure the name exists, we exit from the loop if we go over the size of the array. However, this is not enough in the case where the arrays have "holes" in them, program or map types for which they have no name, but not at the end of the list. This is currently the case for BPF_PROG_TYPE_LSM, not known to bpftool and which name is a null string. When probing for features, bpftool attempts to strlen() that name and segfaults. Let's fix it by skipping probes for "unknown" program and map types, with an informational message giving the numeral value in that case.

2020-07-27Merge branch 'sfc-driver-for-EF100-family-NICs-part-1'David S. Miller
Edward Cree says: ==================== sfc: driver for EF100 family NICs, part 1 EF100 is a new NIC architecture under development at Xilinx, based partly on existing Solarflare technology. As many of the hardware interfaces resemble EF10, support is implemented within the 'sfc' driver, which previous patch series "commonised" for this purpose. In order to maintain bisectability while splitting into patches of a reasonable size, I had to do a certain amount of back-and-forth with stubs for things that the common code may try to call, mainly because we can't do them until we've set up MCDI, but we can't set up MCDI without probing the event queues, at which point a lot of the common machinery becomes reachable from event handlers. Consequently, this first series doesn't get as far as actually sending and receiving packets. I have a second series ready to follow it which implements the datapath (and a few other things like ethtool). Changes from v4: * Fix build on CONFIG_RETPOLINE=n by using plain prototypes instead of INDIRECT_CALLABLE_DECLARE. Changes from v3: * combine both drivers (sfc_ef100 and sfc) into a single module, to make non-modular builds work. Patch #4 now adds a few indirections to support this; the ones in the RX and TX path use indirect-call- wrappers to minimise the performance impact. Changes from v2: * remove MODULE_VERSION. * call efx_destroy_reset_workqueue() from ef100_exit_module(). * correct uint32_ts to u32s. While I was at it, I fixed a bunch of other style issues in the function-control-window code. All in patch #4. Changes from v1: * kernel test robot spotted a link error when sfc_ef100 was built without mdio. It turns out the thing we were trying to link to was a bogus thing to do on anything but Falcon, so new patch #1 removes it from this driver. * fix undeclared symbols in patch #4 by shuffling around prototypes and #includes and adding 'static' where appropriate. * fix uninitialised variable 'rc2' in patch #7. ==================== Signed-off-by: David S.

2020-07-27sfc: remove efx_ethtool_nway_reset()Edward Cree
An MDIO-based n-way restart does not make sense for any of the NICs supported by this driver, nor for the coming EF100. Unlike on Falcon (which was already split off into a separate driver), the PHY on all of Siena, EF10 and EF100 is managed by MC firmware. While Siena can talk to the PHY over MDIO, doing so for anything other than debugging purposes (mdio_mii_ioctl) is likely to confuse the firmware. (According to the SFC firmware team, this support was originally added to the Siena driver early in the development of that product, before it was decided to have firmware manage the PHY.)
