2018-05-29net: Add IFA_RT_PRIORITY address attributeDavid Ahern
Currently, if two interfaces have addresses in the same connected route, then the order of the prefix route entries is determined by the order in which the addresses are assigned or the links brought up. Add IFA_RT_PRIORITY to allow user to specify the metric of the prefix route associated with an address giving interface managers better control of the order of prefix routes.

2018-05-29net/ipv6: Convert ipv6_add_addr to struct ifa6_configDavid Ahern
Move config parameters for adding an ipv6 address to a struct. struct names stem from inet6_rtm_newaddr which is the modern handler for adding an address. Start the conversion to ifa6_config with ipv6_add_addr. This is an argument move only; no functional change intended. Mapping of variable changes: addr --> cfg->pfx peer_addr --> cfg->peer_pfx pfxlen --> cfg->plen flags --> cfg->ifa_flags scope, valid_lft, prefered_lft have the same names within cfg (with corrected spelling).

2018-05-29mlxsw: pci: Utilize MRSR register to perform FW resetJiri Pirko
So far, the PCI BAR0 register is used for triggering FW reset. However, that is a legacy attitude and it is recommended to use MRSR to perform reset instead. So do that. Move the reset into init() function as the cmd interface needs to be used. With that, IRQ initialization needs to be moved as well.

2018-05-29Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 modelsTakashi Iwai
In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174") we tried to address the non-working Atheros BT devices by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made such devices working while it turned out to break other existing chips with the very same USB ID, hence it was reverted afterwards. This is another attempt to tackle the issue. The essential point to use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM- patching. And the previous attempt failed because btusb_setup_qca() returns -ENODEV if the ROM version doesn't match with the expected ones. For some devices that have already the "correct" ROM versions, we may just skip the setup procedure and continue the rest. So, the first fix we'll need is to add a check of the ROM version in the function to skip the setup if the ROM version looks already sane, so that it can be applied for all ath devices. However, the world is a bit more complex than that simple solution. Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's 0x0001 at the beginning of probing, so the device probe always aborts here. In this patch, we add another check of ROM version again, and if the device needs patching, the probe continues. For that, a slight refactoring of btusb_qca_send_vendor_req() was required so that the probe function can pass usb_device pointer directly before allocating hci_dev stuff.

2018-05-29Merge branch 'nfp-abm-RED-MQ-qdisc-offload'David S. Miller
Jakub Kicinski says: ==================== nfp: abm: RED/MQ qdisc offload This is second batch of advanced buffer management nfp driver changes. This series adds the qdisc offload. Support for a very simple subset of RED qdisc offload is added as needed for DCTCP ECN marking (min and max thresholds set to the same value). The first two patches fix glitches introduced by the previous series. We have to be careful about phys_port_name handling, because VFs share the same code path, and some user space may get confused by the names we chose. Since unlike previous offloads we can report the queue backlog both in bytes and packets we need to adjust how statistics are added up in the core (patch 6). There are some extra statistics we want to expose which don't fit into TC stats, namely counts of packets which have been fast- -forwarded without getting enqueued because there was no contention and number of packets that were ever queued (sum of all momentary backlogs). We expose those through ethtool stats (patches 8 and 9). Remaining 5 patches add MQ offload - to be able to set different configurations on different queues. Representors are made multi- -queue and we add offload support to MQ. MQ stats are added up before calling ->dump qdiscs on the children, and therefore don't include updated offload values. To avoid clearly incorrect stats MQ is made to also request stats update from offloads. This way we can correct the diff at the driver level. ==================== Signed-off-by: David S.

Queue levels for simple ECN marking are stored in _abi_nfd_out_q_lvls_X symbol, where X is the PCIe PF id. Find out the location of that symbol and add helpers for modifying it. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ABM NIC FW has a cut-through mode where the PCIe queuing is bypassed, thus working like our standard NIC FWs. Use this mode by default and only enable queuing in switchdev mode where users can configure it.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5e-updates-2018-05-25 This series includes updates for mlx5e netdev driver. 1) Allowr flow based VF vport mirroring under sriov switchdev scheme, added support for offloading the TC mirred mirror sub-action, from Chris Mi. ================= From: Or Gerlitz <ogerlitz@mellanox.com> The user will typically set the actions order such that the mirror port (mirror VF) sees packets as the original port (VF under mirroring) sent them or as it will receive them. In the general case, it means that packets are potentially sent to the mirror port before or after some actions were applied on them. To properly do that, we follow on the exact action order as set for the flow and make sure this will also be the case when we program the HW offload. If all the actions should apply before forwarding to the mirror and dest port, mirroring is just multicasting to the two vports. Otherwise, we split the TC flow to two HW rules, where the 1st applies only the actions needed up to the mirror (if there are such) and the 2nd the rest of the actions plus the forwarding to the dest vport. ================= 2) Move to order-0 only allocations (using fragmented work queues) for all work queues used by the driver, RX and TX descriptor rings (RQs, SQs and Completion Queues (CQs)), from Tariq Toukan. 3) Avoid resetting netdevice statistics on netdevice state changes, from Eran Ben Elisha. ==================== Signed-off-by: David S.

2018-05-29kbuild: add endianness flag to CHEKCFLAGSLuc Van Oostenryck
The kernel depends on macros like __BYTE_ORDER__, __BIG_ENDIAN__ or __LITTLE_ENDIAN__. OTOH, sparse doesn't know about the endianness of the kernel and by default uses the same as the machine on which sparse was built. Ensure that sparse can predefine the macros corresponding to how the kernel was configured by adding -m{big,little}-endian to CHECKFLAGS in the main Makefile (and so for all archs). Also, remove the equivalent done in arch specific Makefiles. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-05-29kbuild: $(CHECK) doesnt need NOSTDINC_FLAGS twiceLuc Van Oostenryck
Currently, $(CHECK) receives NOSTDINC_FLAGS twice: * first directly in the main Makefile via CHECKFLAGS, * then indirectly in scripts/Makefile.build via c_flags. Since once is enough, leave the occurence via c_flags and remove the one via CHECKFLAGS.

2018-05-29netfilter: nf_tables: use call_rcu in netlink dumpsFlorian Westphal
We can make all dumps and lookups lockless. Dumps currently only hold the nfnl mutex on the dump request itself. Dumps can span multiple syscalls, dump continuation doesn't acquire the nfnl mutex anywhere, i.e. the dump callbacks in nf_tables already use rcu and never rely on nfnl mutex being held. So, just switch all dumpers to rcu. This requires taking a module reference before dropping the rcu lock so rmmod is blocked, we also need to hold module reference over the entire dump operation sequence. netlink already supports this via the .module member in the netlink_dump_control struct. For the non-dump case (i.e. lookup of a specific tables, chains, etc), we need to swtich to _rcu list iteration primitive and make sure we use GFP_ATOMIC. This patch also adds the new nft_netlink_dump_start_rcu() helper that takes care of the get_ref, drop-rcu-lock,start dump, get-rcu-lock,put-ref sequence. The helper will be reused for all dumps. Rationale in all dump requests is: - use the nft_netlink_dump_start_rcu helper added in first patch - use GFP_ATOMIC and rcu list iteration - switch to .call_rcu ... thus making all dumps in nf_tables not depend on the nfnl mutex anymore. In the nf_tables_getgen: This callback just fetches the current base sequence, there is no need to serialize this with nfnl nft mutex.
