2020-03-20mac80211: consider WLAN_EID_EXT_HE_OPERATION for parsing CRCJohannes Berg1-1/+5
We use the parsing CRC for checking if the beacon changed, and if the WLAN_EID_EXT_HE_OPERATION extended element changes we need to track it so we can react to that. Include it in the CRC calculation. Link: https://lore.kernel.org/r/20200131111300.891737-22-luca@coelho.fi Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-03-20mac80211: don't leave skb->next/prev pointing to stackJohannes Berg1-1/+5
In beacon protection, don't leave skb->next/prev pointing to the on-stack list, even if that's actually harmless since we don't use them again afterwards. While at it, check that the SKB on the list is still the same, as that's required here. If not, the encryption (protection) code is buggy.

2020-03-20nl80211: add no pre-auth attribute and ext. feature flag for ctrl. portMarkus Theil2-1/+13
If the nl80211 control port is used before this patch, pre-auth frames (0x88c7) are send to userspace uncoditionally. While this enables userspace to only use nl80211 on the station side, it is not always useful for APs. Furthermore, pre-auth frames are ordinary data frames and not related to the control port. Therefore it should for example be possible for pre-auth frames to be bridged onto a wired network on AP side without touching userspace. For backwards compatibility to code already using pre-auth over nl80211, this patch adds a feature flag to disable this behavior, while it remains enabled by default. An additional ext. feature flag is added to detect this from userspace. Thanks to Jouni for pointing out, that pre-auth frames should be handled as ordinary data frames.

This patch adds support for configuring the RGMII skew delays in Rx and Tx. The Rx and Tx skews are set based on the interface mode. By default their configuration is set to the default value in hardware (0.2ns); this means the driver do not rely anymore on the bootloader configuration. Then based on the interface mode being used, a 2ns delay is added: - RGMII_ID adds it for both Rx and Tx. - RGMII_RXID adds it for Rx. - RGMII_TXID adds it for Tx.

Ido Schimmel says: ==================== mlxsw: Offload TC action skbedit priority Petr says: The TC action "skbedit priority P" has the effect of assigning skbprio of P to SKBs that it's applied on. In HW datapath of a switch, the corresponding action is assignment of internal switch priority. Spectrum switches allow setting of packet priority based on an ACL action, which is good match for the skbedit priority gadget. This patchset therefore implements offloading of this action to the Spectrum ACL engine. After a bit of refactoring in patch #1, patch #2 extends the skbedit action to support offloading of "priority" subcommand. On mlxsw side, in patch #3, the QOS_ACTION flexible action is added, with fields necessary for priority adjustment. In patch #4, "skbedit priority" is connected to that action. Patch #5 implements a new forwarding selftest, suitable for both SW- and HW-datapath testing. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2020-03-20net: sched: Do not assume RTNL is held in tunnel key action helpersIdo Schimmel1-2/+6
The cited commit removed RTNL from tc_setup_flow_action(), but the function calls two tunnel key action helpers that use rtnl_dereference() to fetch the action's parameters. This leads to "suspicious RCU usage" warnings [1][2]. Change the helpers to use rcu_dereference_protected() while requiring the action's lock to be held. This is safe because the two helpers are only called from tc_setup_flow_action() which acquires the lock.

2020-03-20net: bridge: vlan: include stats in dumps if requestedNikolay Aleksandrov2-12/+91
This patch adds support for vlan stats to be included when dumping vlan information. We have to dump them only when explicitly requested (thus the flag below) because that disables the vlan range compression and will make the dump significantly larger. In order to request the stats to be included we add a new dump attribute called BRIDGE_VLANDB_DUMP_FLAGS which can affect dumps with the following first flag: - BRIDGE_VLANDB_DUMPF_STATS The stats are intentionally nested and put into separate attributes to make it easier for extending later since we plan to add per-vlan mcast stats, drop stats and possibly STP stats. This is the last missing piece from the new vlan API which makes the dumped vlan information complete. A dump request which should include stats looks like: [BRIDGE_VLANDB_DUMP_FLAGS] |= BRIDGE_VLANDB_DUMPF_STATS A vlandb entry attribute with stats looks like: [BRIDGE_VLANDB_ENTRY] = { [BRIDGE_VLANDB_ENTRY_STATS] = { [BRIDGE_VLANDB_STATS_RX_BYTES] [BRIDGE_VLANDB_STATS_RX_PACKETS] ... } } Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.

2020-03-19net: phy: realtek: read actual speed to detect downshiftHeiner Kallweit1-1/+59
At least some integrated PHY's in RTL8168/RTL8125 chip versions support downshift, and the actual link speed can be read from a vendor-specific register. Info about this register was provided by Realtek. More details about downshift configuration (e.g. number of attempts) aren't available, therefore the downshift tunable is not implemented.

2020-03-19net: sched: Fix hw_stats_type setting in pedit loopPetr Machata1-1/+1
In the commit referenced below, hw_stats_type of an entry is set for every entry that corresponds to a pedit action. However, the assignment is only done after the entry pointer is bumped, and therefore could overwrite memory outside of the entries array. The reason for this positioning may have been that the current entry's hw_stats_type is already set above, before the action-type dispatch. However, if there are no more actions, the assignment is wrong. And if there are, the next round of the for_each_action loop will make the assignment before the action-type dispatch anyway. Therefore fix this issue by simply reordering the two lines.
