of_net: Fix residues after of_get_nvmem_mac_address removal

2019-05-16T17:40:23Z

[ Upstream commit 36ad7022536e0c65f8baeeaa5efde11dec44808a ] I've discovered following discrepancy in the bindings/net/ethernet.txt documentation, where it states following: - nvmem-cells: phandle, reference to an nvmem node for the MAC address; - nvmem-cell-names: string, should be "mac-address" if nvmem is to be.. which is actually misleading and confusing. There are only two ethernet drivers in the tree, cadence/macb and davinci which supports this properties. This nvmem-cell* properties were introduced in commit 9217e566bdee ("of_net: Implement of_get_nvmem_mac_address helper"), but commit afa64a72b862 ("of: net: kill of_get_nvmem_mac_address()") forget to properly clean up this parts. So this patch fixes the documentation by moving the nvmem-cell* properties at the appropriate places. While at it, I've removed unused include as well.

OF: properties: add missing of_node_put

2019-01-16T18:49:53Z

Add an of_node_put when the result of of_graph_get_remote_port_parent is not available. The semantic match that finds this problem is as follows (http://coccinelle.lip6.fr): // @r exists@ local idexpression e; expression x; @@ e = of_graph_get_remote_port_parent(...); ... when != x = e when != true e == NULL when != of_node_put(e) when != of_fwnode_handle(e) ( return e; | *return ...; ) // Signed-off-by: Julia Lawall Cc: stable@vger.kernel.org Signed-off-by: Rob Herring

of: Remove struct device_node.type pointer

2019-01-10T22:24:44Z

Now that all users of device_node.type pointer have been removed in favor of accessor functions, we can remove it. Cc: Frank Rowand Cc: devicetree@vger.kernel.org Signed-off-by: Rob Herring

Pull Devicetree updates from Rob Herring: "The biggest highlight here is the start of using json-schema for DT bindings. Being able to validate bindings has been discussed for years with little progress. - Initial support for DT bindings using json-schema language. This is the start of converting DT bindings from free-form text to a structured format. - Reworking of initrd address initialization. This moves to using the phys address instead of virt addr in the DT parsing code. This rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary rebuilding of lots of files. - Fix stale phandle entries in phandle cache - DT overlay validation improvements. This exposed several memory leak bugs which have been fixed. - Use node name and device_type helper functions in DT code - Last remaining conversions to using %pOFn printk specifier instead of device_node.name directly - Create new common RTC binding doc and move all trivial RTC devices out of trivial-devices.txt. - New bindings for Freescale MAG3110 magnetometer, Cadence Sierra PHY, and Xen shared memory - Update dtc to upstream version v1.4.7-57-gf267e674d145" * tag 'devicetree-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (68 commits) of: __of_detach_node() - remove node from phandle cache of: of_node_get()/of_node_put() nodes held in phandle cache gpio-omap.txt: add reg and interrupts properties dt-bindings: mrvl,intc: fix a trivial typo dt-bindings: iio: magnetometer: add dt-bindings for freescale mag3110 dt-bindings: Convert trivial-devices.txt to json-schema dt-bindings: arm: mrvl: amend Browstone compatible string dt-bindings: arm: Convert Tegra board/soc bindings to json-schema dt-bindings: arm: Convert ZTE board/soc bindings to json-schema dt-bindings: arm: Add missing Xilinx boards dt-bindings: arm: Convert Xilinx board/soc bindings to json-schema dt-bindings: arm: Convert VIA board/soc bindings to json-schema dt-bindings: arm: Convert ST STi board/soc bindings to json-schema dt-bindings: arm: Convert SPEAr board/soc bindings to json-schema dt-bindings: arm: Convert CSR SiRF board/soc bindings to json-schema dt-bindings: arm: Convert QCom board/soc bindings to json-schema dt-bindings: arm: Convert TI nspire board/soc bindings to json-schema dt-bindings: arm: Convert TI davinci board/soc bindings to json-schema dt-bindings: arm: Convert Calxeda board/soc bindings to json-schema dt-bindings: arm: Convert Altera board/soc bindings to json-schema ...

Pull networking updates from David Miller: 1) New ipset extensions for matching on destination MAC addresses, from Stefano Brivio. 2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to nfp driver. From Stefano Brivio. 3) Implement GRO for plain UDP sockets, from Paolo Abeni. 4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT bit so that we could support the entire vlan_tci value. 5) Rework the IPSEC policy lookups to better optimize more usecases, from Florian Westphal. 6) Infrastructure changes eliminating direct manipulation of SKB lists wherever possible, and to always use the appropriate SKB list helpers. This work is still ongoing... 7) Lots of PHY driver and state machine improvements and simplifications, from Heiner Kallweit. 8) Various TSO deferral refinements, from Eric Dumazet. 9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov. 10) Batch dropping of XDP packets in tuntap, from Jason Wang. 11) Lots of cleanups and improvements to the r8169 driver from Heiner Kallweit, including support for ->xmit_more.

From Oz Shlomo and others. 22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and therefore abort the operation before the commit phase (which is the NETDEV_CHANGEADDR event). From Petr Machata. 23) Add indirect call wrappers to avoid retpoline overhead, and use them in the GRO code paths. From Paolo Abeni. 24) Add support for netlink FDB get operations, from Roopa Prabhu. 25) Support bloom filter in mlxsw driver, from Nir Dotan. 26) Add SKB extension infrastructure.

of: __of_detach_node() - remove node from phandle cache

2018-12-21T18:42:36Z

Non-overlay dynamic devicetree node removal may leave the node in the phandle cache. Subsequent calls to of_find_node_by_phandle() will incorrectly find the stale entry. Remove the node from the cache. Add paranoia checks in of_find_node_by_phandle() as a second level of defense (do not return cached node if detached, do not add node to cache if detached).

The phandle cache contains struct device_node pointers. The refcount of the pointers was not incremented while in the cache, allowing use after free error after kfree() of the node.

OF: Add a warning in case chosen node is not present

2018-12-03T23:41:59Z

On architectures that only get their bootargs through devicetree's chosen node (such as RISC-V), that node is mandatory. After a discussion with Rob [1] I'm adding a warning in case chosen node is not present, to let users know about it.
