Getting the pf_id from the function number was a good place to start, but when the PF was setup in passthru mode, the PCI bus/device/function was virtualized and the number in the VM is different from the number in the bare metal. This caused HW configuration issues when the wrong pf_id was used to set up the HMC and other structures. The PF_FUNC_RID register has the real bus/device/function information as configured by the BIOS, so use that for a better number. This works in NPAR mode as well.

The ARQ needs to have at least as many entries as VFs, or the VFs will get errors from the FW when they send messages to the PF. Since we don't know how many VFs we'll end up with, just set up 128 descriptors. Change-ID: I04ae3d1c7faf09110eb782214e9c05aeb62a6c59 Signed-off-by:

There is an order in which this should happen. It turns out that FW will not let you change the Loopback setting of the VSI with update VSI prior to the VEB creation. Change-ID: I7614ddff8b4c37702930c02f16f8c346aaa64bd1 Signed-off-by:

All VSIs on a VEB should either have loopback enabled or disabled, a mixed mode is not supported for a VEB. Since our driver supports multiple VSIs per PF that need to talk to each other make sure to enable Loopback for the PF and FDIR VSI as well. Also, we now have to explicitly enable Loopback mode otherwise we fail VSI creation for VMDq and VF VSIs. Change-ID: Ib68c3ea4aeb730ac9468f930610de456efbe5b20 Signed-off-by:

When multiple VFs attempt to initialize simultaneously, the firmware may delay or drop messages. Make the init code more adept at handling these situations by a) reinitializing the admin queue if the firmware fails to process a request, and b) resending a request if the PF doesn't answer. Once the request has been sent again, the PF might end up getting both requests and send the configuration information to the driver twice. This will cause the VF to complain about receiving an unexpected message from the PF. Since this is not fatal, reduce the warning level of the log messages that are generated in response to this event. Change-ID: I9370a1a2fde2ad3934fa25ccfd0545edfbbb4805 Signed-off-by:

The old xxx_NETDEV_STAT() macro was defined long before the newer rtnl_link_stats64 came into being, and just never got updated. Since we're using rtnl_link_stats64 in other parts of the driver, we should use it here as well. We've just been lucky that the field definitions are the same sizes.

Resolve an issue related to images with multiple PFs per physical port. We cannot fully support 1588 PTP features, since only one port should control (ie: write) the registers at a time. Doing so can cause interference of functionality. It may be possible to partially implement the API for only those features without side effects. However, this at minimum means non controlling PFs lose Tx timestamps, frequency atunement, and possibly SYSTIME adjustment. There may be further impact I did not discover. Since the API in the kernel expects these features to work, it is simpler and less dangerous to just disable PTP features on all PFs not identified as the controlling PF in PRTTSYN_CTL0.PF_ID. This change also removes the warning printed when hwtstaml IOCTL is called on the wrong PF. This is actually meaningless now, since only one PF per port will support it. In addition, the ethtool get_ts_info IOCTL was updated so that only the controlling port will even indicate support (so as not to confuse users). The overall downside is complete loss of functionality on non controlling PF, vs the possible gain of partial support. The biggest factor for choosing this approach is simplicity and ensuring that the main PF will work. There could easily be other portions of the 1588 logic with side effects I am not aware, and the reduced functionality that might be made available is significantly less useful. In addition, the API does not allow for proper indication of why particular features are not supported. These reasons are enough to decide for the simpler approach to resolving this issue.

Alexei Starovoitov says: ==================== allow eBPF programs to be attached to sockets V1->V2: fixed comments in sample code to state clearly that packet data is accessed with LD_ABS instructions and not internal skb fields. Also replaced constants in: BPF_LD_ABS(BPF_B, 14 + 9 /* R0 = ip->proto */), with: BPF_LD_ABS(BPF_B, ETH_HLEN + offsetof(struct iphdr, protocol) /* R0 = ip->proto */), V1 cover: Introduce BPF_PROG_TYPE_SOCKET_FILTER type of eBPF programs that can be attached to sockets with setsockopt(). Allow such programs to access maps via lookup/update/delete helpers. This feature was previewed by bpf manpage in commit b4fc1a46("Merge branch 'bpf-next'") Now it can actually run. 1st patch adds LD_ABS/LD_IND instruction verification and 2nd patch adds new setsockopt() flag. Patches 3-6 are examples in assembler and in C. Though native eBPF programs are way more powerful than classic filters (attachable through similar setsockopt() call), they don't have skb field accessors yet. Like skb->pkt_type, skb->dev->ifindex are not accessible. There are sevaral ways to achieve that. That will be in the next set of patches. So in this set native eBPF programs can only read data from packet and access maps. The most powerful example is sockex2_kern.c from patch 6 where ~200 lines of C are compiled into ~300 of eBPF instructions. It shows how quite complex packet parsing can be done. LLVM used to build examples is at https://github.com/iovisor/llvm which is fork of llvm trunk that I'm cleaning up for upstreaming. ==================== Signed-off-by:

sockex2_kern.c is purposefully large eBPF program in C. llvm compiles ~200 lines of C code into ~300 eBPF instructions. It's similar to __skb_flow_dissect() to demonstrate that complex packet parsing can be done by eBPF. Then it uses (struct flow_keys)->dst IP address (or hash of ipv6 dst) to keep stats of number of packets per IP. User space loads eBPF program, attaches it to loopback interface and prints dest_ip->#packets stats every second. Usage: $sudo samples/bpf/sockex2 ip 127.0.0.1 count 19 ip 127.0.0.1 count 178115 ip 127.0.0.1 count 369437 ip 127.0.0.1 count 559841 ip 127.0.0.1 count 750539 Signed-off-by:

this example does the same task as previous socket example in assembler, but this one does it in C. eBPF program in kernel does: /* assume that packet is IPv4, load one byte of IP->proto */ int index = load_byte(skb, ETH_HLEN + offsetof(struct iphdr, protocol)); long *value; value = bpf_map_lookup_elem(&my_map, &index); if (value) __sync_fetch_and_add(value, 1); Corresponding user space reads map[tcp], map[udp], map[icmp] and prints protocol stats every second Signed-off-by: -

this socket filter example does: - creates arraymap in kernel with key 4 bytes and value 8 bytes - loads eBPF program which assumes that packet is IPv4 and loads one byte of IP->proto from the packet and uses it as a key in a map r0 = skb->data[ETH_HLEN + offsetof(struct iphdr, protocol)]; *(u32*)(fp - 4) = r0; value = bpf_map_lookup_elem(map_fd, fp - 4); if (value) (*(u64*)value) += 1; - attaches this program to raw socket - every second user space reads map[IPPROTO_TCP], map[IPPROTO_UDP], map[IPPROTO_ICMP] to see how many packets of given protocol were seen on loopback interface Usage: $sudo samples/bpf/sock_example TCP 0 UDP 0 ICMP 0 packets TCP 187600 UDP 0 ICMP 4 packets TCP 376504 UDP 0 ICMP 8 packets TCP 563116 UDP 0 ICMP 12 packets TCP 753144 UDP 0 ICMP 16 packets Signed-off-by: -

introduce new setsockopt() command: setsockopt(sock, SOL_SOCKET, SO_ATTACH_BPF, &prog_fd, sizeof(prog_fd)) where prog_fd was received from syscall bpf(BPF_PROG_LOAD, attr, ...) and attr->prog_type == BPF_PROG_TYPE_SOCKET_FILTER setsockopt() calls bpf_prog_get() which increments refcnt of the program, so it doesn't get unloaded while socket is using the program. The same eBPF program can be attached to multiple sockets. User task exit automatically closes socket which calls sk_filter_uncharge() which decrements refcnt of eBPF program Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following batch contains netfilter updates for net-next. Basically, enhancements for xt_recent, skip zeroing of timer in conntrack, fix linking problem with recent redirect support for nf_tables, ipset updates and a couple of cleanups. More specifically, they are: 1) Rise maximum number per IP address to be remembered in xt_recent while retaining backward compatibility, from Florian Westphal. 2) Skip zeroing timer area in nf_conn objects, also from Florian. 3) Inspect IPv4 and IPv6 traffic from the bridge to allow filtering using using meta l4proto and transport layer header, from Alvaro Neira. 4) Fix linking problems in the new redirect support when CONFIG_IPV6=n and IP6_NF_IPTABLES=n. And ipset updates from Jozsef Kadlecsik: 5) Support updating element extensions when the set is full (fixes netfilter bugzilla id 880). 6) Fix set match with 32-bits userspace / 64-bits kernel. 7) Indicate explicitly when /0 networks are supported in ipset. 8) Simplify cidr handling for hash:*net* types. 9) Allocate the proper size of memory when /0 networks are supported. 10) Explicitly add padding elements to hash:net,net and hash:net,port, because the elements must be u32 sized for the used hash function. Jozsef is also cooking ipset RCU conversion which should land soon if they reach the merge window in time. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-12-05 This series contains updates to ixgbe and ixgbevf. Alex provides a couple of patches to cleanup ixgbe. First cleans up the page reuse code getting it into a state where all the workarounds needed are in place as well as cleaning up a few minor oversights such as using __free_pages instead of put_page to drop a locally allocated page. Then cleans up the tail writes for the ixgbe descriptor queues. Mark Peterson adds support to lookup MAC addresses in Open Firmware or IDPROM. Emil provides patches for ixgbe and ixgbevf to fix an issue on rmmod and to add support for X550 in the VF driver. First removes the read/write operations to the CIAA/D registers since it can block access to the PCI config space and make use of standard kernel functions for accessing the PCI config space. Then fixes an issue where the driver has logic to free up used data in case any of the checks in ixgbe_probe() fail, however there is a similar set of cleanups that can occur on driver unload in ixgbe_remove() which can cause the rmmod command to crash. Don provides the remaining patches in the series to complete the addition of X550 support into the ixgbe driver. ==================== Signed-off-by:

This patch resolves couple of issues in ixgbevf_probe/remove(): 1. Fix a case where adapter->state is tested after free_netdev() this is same as the patch for ixgbe from Daniel Borkmann <dborkman@redhat.com>: commit b5b2ffc0 ("ixgbe: fix use after free adapter->state test in ixgbe_remove/ixgbe_probe") 2. Move pci_set_drvdata() after all the error checks in ixgbevf_probe() and then add a check in ixgbevf_probe() to avoid running the cleanup functions twice in cases where probe failed.

Currently the shared code checksum calculation function only returns a u16 and cannot return an error code. Unfortunately a variety of errors can happen that completely prevent the calculation of a checksum. So, change the function return value from a u16 to an s32 and return a negative value on error, or the positive checksum value when there is no error. Signed-off-by:
