Phylink made an assumption about the carrier state being down when calling phylink_start(). If this assumption isn't satisfied, the internal phylink state could misbehave and a net device could end up not being functional. This patch fixes this by explicitly calling netif_carrier_off() in phylink_start(). Signed-off-by:

Antoine Tenart says: ==================== net: mvpp2: improve the interrupt usage This series aims to improve the interrupts descriptions and usage in the Marvell PPv2 driver. - Before the series interrupts were named after their s/w usage, which in fact can be configured. The series rename all those interrupts and add a description of the ones left over. - In PPv2 the interrupts are mapped to vectors. Those vectors were directly mapped to a given CPU, and per-cpu accesses were done. While this worked on our cases, the registers accesses mapped to the vectors are not actually linked to a given CPU. They instead are linked to what is called a "s/w thread". The series modify this so that the s/w threads are used instead of the CPU numbers, by adding an indirection. This means we now can have systems with more CPUs than s/w threads. This is based on today's net-next, and was tested on various boards using both versions of the PPv2 engine. Two more patches will be coming, to update the device trees describing a PPv2 engine. The patches are ready, but will go through a different tree. I'll send them once this series will be accepted. This is not an issue as the PPv2 driver keeps the dt bindings backward compatibility. ==================== Signed-off-by: -

As the mvpp2_percpu_read/write/... functions aren't really per-cpu but per s/w thread, rename them to include 'thread' instead of 'percpu'. This is a cosmetic patch. Signed-off-by:

The Marvell PPv2 network controller has 9 internal threads. The driver works fine when there are less CPUs available than threads. This isn't true if more CPUs are available. As this is a valid use case, handle this particular case. Signed-off-by:

The Marvell PPv2.2 engine only has 8 Rx queues per CPU, while PPv2.1 has 16 of them. This patch updates the code so that the Rx queues mask width is selected given the version of the network controller used. Signed-off-by:

This patch updates the probing function so that the queue mode isn't updated while probing, as the driver would silently end up using a configuration not wanted by the user. The patch adds an extra check to validate the chosen queue mode instead, and the driver will fail to probe if the configuration is invalid. Signed-off-by:

This patch renames the IRQs in the Marvell PPv2 driver as their current names match the way they are used in software. But this will change in the future, and those IRQs have nothing to do with Rx/Tx interrupts (this can be configured). The new binding also describe more interrupts as some where left out. The old binding support is kept for backward compatibility. Signed-off-by:

This patch sets the number of s/w threads to 9, its maximum value, instead of 8. This is not a fix as only 4 of the s/w threads were used so far, but more could be used in the future. Signed-off-by:

Heiner Kallweit says: ==================== net: phy: make phy_stop() synchronous There have been few not that successful attempts in the past to make phy_stop() a synchronous call instead of just changing the state. Patch 1 of this series addresses an issue which prevented this change. At least for me it works fine now. Would appreciate if Geert could re-test as well that suspend doesn't throw an error. ==================== Signed-off-by: -

phy_stop() may be called e.g. when suspending, therefore all needed actions should be performed synchronously. Therefore add a synchronous call to the state machine. Signed-off-by:

When bringing down the netdevice (incl. detaching it) and calling netif_carrier_off directly or indirectly the latter triggers an asynchronous linkwatch event. This linkwatch event eventually may fail to access chip registers in the ndo_get_stats/ndo_get_stats64 callback because the device isn't accessible any longer, see call trace in [0]. To prevent this scenario don't check for IFF_UP only, but also make sure that the netdevice is present. [0] https://lists.openwall.net/netdev/2018/03/15/62Signed-off-by:

Commonly, ethernet addresses are just using a policy of { .len = ETH_ALEN } which leaves userspace free to send more data than it should, which may hide bugs. Introduce NLA_EXACT_LEN which checks for exact size, rejecting the attribute if it's not exactly that length. Also add NLA_EXACT_LEN_WARN which requires the minimum length and will warn on longer attributes, for backward compatibility. Use these to define NLA_POLICY_ETH_ADDR (new strict policy) and NLA_POLICY_ETH_ADDR_COMPAT (compatible policy with warning); these are used like this: static const struct nla_policy <name>[...] = { [NL_ATTR_NAME] = NLA_POLICY_ETH_ADDR, ... }; Signed-off-by:Johannes Berg <johannes.berg@intel.com> Reviewed-by:

In some situations some netlink attributes may be used for output only (kernel->userspace) or may be reserved for future use. It's then helpful to be able to prevent userspace from using them in messages sent to the kernel, since they'd otherwise be ignored and any future will become impossible if this happens. Add NLA_REJECT to the policy which does nothing but reject (with EINVAL) validation of any messages containing this attribute. Allow for returning a specific extended ACK error message in the validation_data pointer. While at it clear up the documentation a bit - the NLA_BITFIELD32 documentation was added to the list of len field descriptions. Also, use NL_SET_BAD_ATTR() in one place where it's open-coded. The specific case I have in mind now is a shared nested attribute containing request/response data, and it would be pointless and potentially confusing to have userspace include response data in the messages that actually contain a request.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-09-18 This series contains changes to i40evf so that it becomes a more generic virtual function driver for current and future silicon. While doing the rename of i40evf to a more generic name of iavf, we also put the driver on a severe diet due to how much of the code was unneeded or was unused. The outcome is a lean and mean virtual function driver that continues to work on existing 40GbE (i40e) virtual devices and prepped for future supported devices, like the 100GbE (ice) virtual devices. This solves 2 issues we saw coming or were already present, the first was constant code duplication happening with i40e/i40evf, when much of the duplicate code in the i40evf was not used or was not needed. The second was to remove the future confusion of why future VF devices that were not considered "40GbE" only devices were supported by i40evf. The thought is that iavf will be the virtual function driver for all future devices, so it should have a "generic" name to properly represent that it is the VF driver for multiple generations of devices. The last patch in this series is unreleated to the iavf conversion and just has to do with a MODULE_LICENSE correction. Known Caveats: Existing user space configurations may have to change, but the module alias in patch 1 helps a bit here. ==================== Signed-off-by:
