2018-01-18selftest/bpf: extend the offload test with map checksJakub Kicinski3-25/+218
Check map device information is reported correctly, and perform basic map operations. Check device destruction gets rid of the maps and map allocation failure path by telling netdevsim to reject map offload via DebugFS.

2018-01-18netdevsim: bpf: support fake map offloadJakub Kicinski2-0/+249
Add to netdevsim ability to pretend it's offloading BPF maps. We only allow allocation of tiny 2 entry maps, to keep things simple. Mutex lock may seem heavy for the operations we perform, but we want to make sure callbacks can sleep.

The current architecture detection method in bpftool is designed for host case. For offload case, we can't use the architecture of "bpftool" itself. Instead, we could call the existing "ifindex_to_name_ns" to get DEVNAME, then read pci id from /sys/class/dev/DEVNAME/device/vendor, finally we map vendor id to bfd arch name which will finally be used to select bfd backend for the disassembler.

2018-01-18bpf: add new jited info fields in bpf_dev_offload and bpf_prog_infoJiong Wang3-13/+43
For host JIT, there are "jited_len"/"bpf_func" fields in struct bpf_prog used by all host JIT targets to get jited image and it's length. While for offload, targets are likely to have different offload mechanisms that these info are kept in device private data fields. Therefore, BPF_OBJ_GET_INFO_BY_FD syscall needs an unified way to get JIT length and contents info for offload targets. One way is to introduce new callback to parse device private data then fill those fields in bpf_prog_info. This might be a little heavy, the other way is to add generic fields which will be initialized by all offload targets. This patch follow the second approach to introduce two new fields in struct bpf_dev_offload and teach bpf_prog_get_info_by_fd about them to fill correct jited_prog_len and jited_prog_insns in bpf_prog_info.

peernet2id_alloc() is racy without rtnl_lock() as refcount_read(&peer->count) under net->nsid_lock does not guarantee, peer is alive: rcu_read_lock() peernet2id_alloc() .. spin_lock_bh(&net->nsid_lock) .. refcount_read(&peer->count) (!= 0) .. .. put_net() .. cleanup_net() .. for_each_net(tmp) .. spin_lock_bh(&tmp->nsid_lock) .. __peernet2id(tmp, net) == -1 .. .. .. .. __peernet2id_alloc(alloc == true) .. .. .. rcu_read_unlock() .. .. synchronize_rcu() .. kmem_cache_free(net) After the above situation, net::netns_id contains id pointing to freed memory, and any other dereferencing by the id will operate with this freed memory. Currently, peernet2id_alloc() is used under rtnl_lock() everywhere except ovs_vport_cmd_fill_info(), and this race can't occur. But peernet2id_alloc() is generic interface, and better we fix it before someone really starts use it in wrong context. v2: Don't place refcount_read(&net->count) under net->nsid_lock as suggested by Eric W.

2018-01-17net: sched: use block index as a handle instead of qdisc when block is sharedJiri Pirko2-84/+128
As the tcm_ifindex with value TCM_IFINDEX_MAGIC_BLOCK is invalid ifindex, use it to indicate that we work with block, instead of qdisc. So if tcm_ifindex is set to TCM_IFINDEX_MAGIC_BLOCK, tcm_parent is used to carry block_index. If the block is set to be shared between at least 2 qdiscs, it is forbidden to use the qdisc handle to add/delete filters. In that case, userspace has to pass block_index. Also, for dump of the filters, in case the block is shared in between at least 2 qdiscs, the each filter is dumped with tcm_ifindex value TCM_IFINDEX_MAGIC_BLOCK and tcm_parent set to block_index. That gives the user clear indication, that the filter belongs to a shared block and not only to one qdisc under which it is dumped.

2018-01-17bnxt_en: Restore MSIX after disabling SRIOV.Michael Chan2-3/+15
After SRIOV has been enabled and disabled, the MSIX vectors assigned to the VFs have to be re-initialized. Otherwise they cannot be re-used by the PF. For example, increasing the number of PF rings after disabling SRIOV may fail if the PF uses MSIX vectors previously assigned to the VFs. To fix this, we add logic in bnxt_restore_pf_fw_resources() to close the NIC, clear and re-init MSIX, and re-open the NIC.

2018-01-17bnxt_en: Refactor bnxt_close_nic().Michael Chan1-13/+19
Add a new __bnxt_close_nic() function to do all the work previously done in bnxt_close_nic() except waiting for SRIOV configuration. The new function will be used in the next patch as part of SRIOV cleanup. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-01-17bnxt_en: Update firmware interface to 1.9.0.Michael Chan3-6107/+5854
The version has new firmware APIs to allocate PF/VF resources more flexibly. New toolchains were used to generate this file, resulting in a one-time large diffstat. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
