2019-04-27net: ethernet: ti: davinci_mdio: use devm_ioremap()Grygorii Strashko
The Davinci MDIO in most of the case implemented as module inside of TI CPSW subsystem and fully depends on CPSW to be enabled, but historically it's implemented as separate Platform device/driver and defined in DT files in two ways: - as standalone node - as child node of CPSW subsystem. In later case it's required to split CPSW subsystem "reg" property to exclude MDIO I/O range which is not useful. Hence, replace devm_ioremap_resource() with devm_ioremap() to allow define full I/O range in parent CPSW subsystem without spliting.

Now CPSW ALE will set/clean Host port bit in Unregistered Multicast Flood Mask (UNREG_MCAST_FLOOD_MASK) for every VLAN without checking if this port belongs to VLAN or not when ALLMULTI mode flag is set for nedev. This is working in non dual_mac mode, but in dual_mac - it causes enabling/disabling ALLMULTI flag for both ports. Hence fix it by adding additional parameter to cpsw_ale_set_allmulti() to specify ALE port number for which ALLMULTI has to be enabled and check if port belongs to VLAN before modifying UNREG_MCAST_FLOOD_MASK.

2019-04-27genetlink: optionally validate strictly/dumpsJohannes Berg
Add options to strictly validate messages and dump messages, sometimes perhaps validating dump messages non-strictly may be required, so add an option for that as well. Since none of this can really be applied to existing commands, set the options everwhere using the following spatch: @@ identifier ops; expression X; @@ struct genl_ops ops[] = { ..., { .cmd = X, + .validate = GENL_DONT_VALIDATE_STRICT | GENL_DONT_VALIDATE_DUMP, ... }, ... }; For new commands one should just not copy the .validate 'opt-out' flags and thus get strict validation.

2019-04-27netlink: make validation more configurable for future strictnessJohannes Berg
We currently have two levels of strict validation: 1) liberal (default) - undefined (type >= max) & NLA_UNSPEC attributes accepted - attribute length >= expected accepted - garbage at end of message accepted 2) strict (opt-in) - NLA_UNSPEC attributes accepted - attribute length >= expected accepted Split out parsing strictness into four different options: * TRAILING - check that there's no trailing data after parsing attributes (in message or nested) * MAXTYPE - reject attrs > max known type * UNSPEC - reject attributes with NLA_UNSPEC policy entries * STRICT_ATTRS - strictly validate attribute size The default for future things should be *everything*. The current *_strict() is a combination of TRAILING and MAXTYPE, and is renamed to _deprecated_strict(). The current regular parsing has none of this, and is renamed to *_parse_deprecated(). Additionally it allows us to selectively set one of the new flags even on old policies. Notably, the UNSPEC flag could be useful in this case, since it can be arranged (by filling in the policy) to not be an incompatible userspace ABI change, but would then going forward prevent forgetting attribute entries. Similar can apply to the POLICY flag. We end up with the following renames: * nla_parse -> nla_parse_deprecated * nla_parse_strict -> nla_parse_deprecated_strict * nlmsg_parse -> nlmsg_parse_deprecated * nlmsg_parse_strict -> nlmsg_parse_deprecated_strict * nla_parse_nested -> nla_parse_nested_deprecated * nla_validate_nested -> nla_validate_nested_deprecated Using spatch, of course: @@ expression TB, MAX, HEAD, LEN, POL, EXT; @@ -nla_parse(TB, MAX, HEAD, LEN, POL, EXT) +nla_parse_deprecated(TB, MAX, HEAD, LEN, POL, EXT) @@ expression NLH, HDRLEN, TB, MAX, POL, EXT; @@ -nlmsg_parse(NLH, HDRLEN, TB, MAX, POL, EXT) +nlmsg_parse_deprecated(NLH, HDRLEN, TB, MAX, POL, EXT) @@ expression NLH, HDRLEN, TB, MAX, POL, EXT; @@ -nlmsg_parse_strict(NLH, HDRLEN, TB, MAX, POL, EXT) +nlmsg_parse_deprecated_strict(NLH, HDRLEN, TB, MAX, POL, EXT) @@ expression TB, MAX, NLA, POL, EXT; @@ -nla_parse_nested(TB, MAX, NLA, POL, EXT) +nla_parse_nested_deprecated(TB, MAX, NLA, POL, EXT) @@ expression START, MAX, POL, EXT; @@ -nla_validate_nested(START, MAX, POL, EXT) +nla_validate_nested_deprecated(START, MAX, POL, EXT) @@ expression NLH, HDRLEN, MAX, POL, EXT; @@ -nlmsg_validate(NLH, HDRLEN, MAX, POL, EXT) +nlmsg_validate_deprecated(NLH, HDRLEN, MAX, POL, EXT) For this patch, don't actually add the strict, non-renamed versions yet so that it breaks compile if I get it wrong. Also, while at it, make nla_validate and nla_parse go down to a common __nla_validate_parse() function to avoid code duplication. Ultimately, this allows us to have very strict validation for every new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the next patch, while existing things will continue to work as is. In effect then, this adds fully strict validation for any new command. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-27netlink: make nla_nest_start() add NLA_F_NESTED flagMichal Kubecek
Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most netlink based interfaces (including recently added ones) are still not setting it in kernel generated messages. Without the flag, message parsers not aware of attribute semantics (e.g. wireshark dissector or libmnl's mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display the structure of their contents. Unfortunately we cannot just add the flag everywhere as there may be userspace applications which check nlattr::nla_type directly rather than through a helper masking out the flags. Therefore the patch renames nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start() as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually are rewritten to use nla_nest_start(). Except for changes in include/net/netlink.h, the patch was generated using this semantic patch: @@ expression E1, E2; @@ -nla_nest_start(E1, E2) +nla_nest_start_noflag(E1, E2) @@ expression E1, E2; @@ -nla_nest_start_noflag(E1, E2 | NLA_F_NESTED) +nla_nest_start(E1, E2) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Jiri Pirko <jiri@mellanox.com> Acked-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.

2019-04-26net: phy: improve genphy_soft_resetHeiner Kallweit
PHY's behave differently when being reset. Some reset registers to defaults, some don't. Some trigger an autoneg restart, some don't. So let's also set the autoneg restart bit when resetting. Then PHY behavior should be more consistent. Clearing BMCR_ISOLATE serves the same purpose and is borrowed from genphy_restart_aneg. BMCR holds the speed / duplex settings in fixed mode. Therefore we may have an issue if a soft reset resets BMCR to its default. So better call genphy_setup_forced() afterwards in fixed mode.

2019-04-26mac80211_hwsim: Extended Key ID supportAlexander Wetzel
Allow Extended Key ID to be used with hwsim. Hwsim can only communicate with other hwsim cards, allowing it to bypass creation of A-MPDUs in the first place. Mixing keyIDs in an A-MPDU is therefore impossible and can never cause interoperability issues with other cards.

2019-04-26netdevsim: move netdev creation/destruction to dev probeJiri Pirko
Remove the existing way to create netdevsim over rtnetlink and move the netdev creation/destruction to dev probe, so for every probed port, a netdevsim-netdev instance is created. Adjust selftests to work with new interface. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-26netdevsim: extend device attrs to support port addition and deletionJiri Pirko
In order to test flows in core, it is beneficial to maintain previously supported possibility to add and delete ports during netdevsim lifetime. Do it by extending device sysfs attrs by "new_port" and "del_port". Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-26netdevsim: implement dev probe/remove skeleton with port initializationJiri Pirko
Implement netdevsim bus probing of netdevsim devices. For every probed device create a devlink instance.

2019-04-26netdevsim: change debugfs tree topologyJiri Pirko
With the model where dev is represented by devlink and ports are represented by devlink ports, make debugfs file names independent on netdev names. Change the topology to the one illustrated by the following example: $ ls /sys/kernel/debug/netdevsim/ netdevsim1 $ ls /sys/kernel/debug/netdevsim/netdevsim1/ bpf_bind_accept bpf_bind_verifier_delay bpf_bound_progs ports $ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/ 0 1 $ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/0/ bpf_map_accept bpf_offloaded_id bpf_tc_accept bpf_tc_non_bound_accept bpf_xdpdrv_accept bpf_xdpoffload_accept dev ipsec $ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/0/dev -l lrwxrwxrwx 1 root root 0 Apr 13 15:58 /sys/kernel/debug/netdevsim/netdevsim1/ports/0/dev -> ../../../netdevsim1 Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
