Use of_match_ptr() on xrs700x_mdio_dt_ids so that NULL is substituted when CONFIG_OF isn't defined. This will prevent unnecessary use of xrs700x_mdio_dt_ids when CONFIG_OF isn't defined.

Eric Dumazet says: ==================== tcp: RFC 6056 induced changes This is based on a report from David Dworken. First patch implements RFC 6056 3.3.4 proposal.

2021-02-11tcp: add some entropy in __inet_hash_connect()Eric Dumazet
Even when implementing RFC 6056 3.3.4 (Algorithm 4: Double-Hash Port Selection Algorithm), a patient attacker could still be able to collect enough state from an otherwise idle host. Idea of this patch is to inject some noise, in the cases __inet_hash_connect() found a candidate in the first attempt. This noise should not significantly reduce the collision avoidance, and should be zero if connection table is already well used. Note that this is not implementing RFC 6056 3.3.5 because we think Algorithm 5 could hurt typical workloads.

2021-02-11tcp: change source port randomizarion at connect() timeEric Dumazet
RFC 6056 (Recommendations for Transport-Protocol Port Randomization) provides good summary of why source selection needs extra care. David Dworken reminded us that linux implements Algorithm 3 as described in RFC 6056 3.3.3 Quoting David : In the context of the web, this creates an interesting info leak where websites can count how many TCP connections a user's computer is establishing over time. For example, this allows a website to count exactly how many subresources a third party website loaded. This also allows: - Distinguishing between different users behind a VPN based on distinct source port ranges. - Tracking users over time across multiple networks. - Covert communication channels between different browsers/browser profiles running on the same computer - Tracking what applications are running on a computer based on the pattern of how fast source ports are getting incremented. Section 3.3.4 describes an enhancement, that reduces attackers ability to use the basic information currently stored into the shared 'u32 hint'. This change also decreases collision rate when multiple applications need to connect() to different destinations.

2021-02-11Revert "net-loopback: set lo dev initial state to UP"Petr Machata
In commit c9dca822c729 ("net-loopback: set lo dev initial state to UP"), linux started automatically bringing up the loopback device of a newly created namespace. However, an existing user script might reasonably have the following stanza when creating a new namespace -- and in fact at least tools/testing/selftests/net/fib_nexthops.sh in Linux's very own testsuite does: # set -e # ip netns add foo # ip -netns foo addr add 127.0.0.1/8 dev lo # ip -netns foo link set lo up # set +e This will now fail, because the kernel reasonably rejects "ip addr add" of a duplicate address. The described change of behavior therefore constitutes a breakage. Revert it.

2021-02-11net: phy: introduce phydev->portMichael Walle
At the moment, PORT_MII is reported in the ethtool ops. This is odd because it is an interface between the MAC and the PHY and no external port. Some network card drivers will overwrite the port to twisted pair or fiber, though. Even worse, the MDI/MDIX setting is only used by ethtool if the port is twisted pair. Set the port to PORT_TP by default because most PHY drivers are copper ones. If there is fibre support and it is enabled, the PHY driver will set it to PORT_FIBRE. This will change reporting PORT_MII to either PORT_TP or PORT_FIBRE; except for the genphy fallback driver.

2021-02-11wilc1000: Fix use of void pointer as a wrong struct typeVsevolod Kozlov
ac_classify() expects a struct sk_buff* as its second argument, which is a member of struct tx_complete_data. priv happens to be a pointer to struct tx_complete_data, so passing it directly to ac_classify() leads to wrong behaviour and occasional panics. Since there is only one caller of wilc_wlan_txq_add_net_pkt and it already knows the type behind this pointer, and the structure is already in the header file, change the function signature to use the real type instead of void* in order to prevent confusion.

If the SKU_ID doesn't match, we don't increment the pointer and keep checking the same TLV over and over again. We need to increment the pointer in all situtations, namely if the TLV is not a SKU_ID, if the SKU_ID matched or if the SKU_ID didn't match. So we can increment the pointer already before checking for these conditions to solve the problem.

Call set_pnvm when the PNVM is already loaded and change the trans_pcie implementation to accept a second call to set_pnvm when we have already allocated and, in this case, only set the values without allocating again.

2021-02-11iwlwifi: mvm: reduce the print severity of failing getting NIC tempGolan Ben Ami
Currently, for all devices and families, failing getting the temp from the fw is indicated in the log as ERR. This is too severe for two reasons: 1. The driver has a fall back - and schedules the next temp read immediately after failing to read temp from the fw. 2. The temp read implementation in the fw is different between HWs, and on older devices the flow is a-sync and may timeout. Reducing the print severity from ERR to WARN will allow to track the issue if it will appear many times, but not frighten users if it appears once.
