2018-03-02Merge branch 'bpftool-visualization'Alexei Starovoitov7-285/+1010
Jakub Kicinski says: ==================== Jiong says: This patch set is an application of CFG information on eBPF program visualization. It presents some initial code for building CFG information from eBPF instruction sequences. After we get eBPF program bytecode, we do sub-program detection and basic-block partition. These information then are visualized into DOT graph. The user could use any DOT graphic tools (xdot, graphviz etc) to view it. For example: bpftool prog dump xlated id 2 visual &>output.dot [xdot | dotty] output.dot dot -Tpng -o output.png This initial patch set hasn't tuned much on the dot description layout nor decoration, we could improve them later once the direction of the patch set is agreed on. We could also visualize some static analysis performance data. v2 (Jakub): - update license headers and add SPDX tags. ==================== Acked-by: David S.

2018-03-02tools: bpftool: generate .dot graph from CFG informationJiong Wang3-0/+147
This patch let bpftool print .dot graph file into stdout. This graph is generated by the following steps: - iterate through the function list. - generate basic-block(BB) definition for each BB in the function. - draw out edges to connect BBs. This patch is the initial support, the layout and decoration of the .dot graph could be improved. Also, it will be useful if we could visualize some performance data from static analysis.

2018-03-02tools: bpftool: partition basic-block for each function in the CFGJiong Wang1-1/+117
This patch partition basic-block for each function in the CFG. The algorithm is simple, we identify basic-block head in a first traversal, then second traversal to identify the tail. We could build extended basic-block (EBB) in next steps. EBB could make the graph more readable when the eBPF sequence is big.

2018-03-02tools: bpftool: detect sub-programs from the eBPF sequenceJiong Wang2-0/+190
This patch detect all sub-programs from the eBPF sequence and keep the information in the new CFG data structure. The detection algorithm is basically the same as the one in verifier except we need to use insn->off instead of insn->imm to get the pc-relative call offset. Because verifier has modified insn->off/insn->imm during finishing the verification. Also, we don't need to do some sanity checks as verifier has done them.

2018-03-01ipv6: allow userspace to add IFA_F_OPTIMISTIC addressesSabrina Dubroca1-1/+34
According to RFC 4429 (section 3.1), adding new IPv6 addresses as optimistic addresses is acceptable, as long as the implementation follows some rules: * Optimistic DAD SHOULD only be used when the implementation is aware that the address is based on a most likely unique interface identifier (such as in [RFC2464]), generated randomly [RFC3041], or by a well-distributed hash function [RFC3972] or assigned by Dynamic Host Configuration Protocol for IPv6 (DHCPv6) [RFC3315]. Optimistic DAD SHOULD NOT be used for manually entered addresses. Thus, it seems reasonable to allow userspace to set the optimistic flag when adding new addresses. We must not let userspace set NODAD + OPTIMISTIC, since if the kernel is not performing DAD we would never clear the optimistic flag. We must also ignore userspace's request to add OPTIMISTIC flag to addresses that have already completed DAD (addresses that don't have the TENTATIVE flag, or that have the DADFAILED flag). Then we also need to clear the OPTIMISTIC flag on permanent addresses when DAD fails. Otherwise, IFA_F_OPTIMISTIC addresses added by userspace can still be used after DAD has failed, because in ipv6_chk_addr_and_flags(), IFA_F_OPTIMISTIC overrides IFA_F_TENTATIVE. Setting IFA_F_OPTIMISTIC from userspace is conditional on CONFIG_IPV6_OPTIMISTIC_DAD and the optimistic_dad sysctl.

As a part of working on MII time stamping infrastructure, I was trying to figure out how netdev->phydev gets assigned, and I stumbled across this. Ever since the new phylink code came in, the field is assigned twice. The function, phylink_connect_phy(), calls phy_attach_direct() phylink_bringup_phy() and phy_attach_direct() sets dev->phydev = phydev; but phylink_bringup_phy() then sets the same field again: pl->netdev->phydev = phy; Similarly, the function, phylink_of_phy_connect(), calls of_phy_attach() phy_attach_direct() phylink_bringup_phy() The removal code is also duplicated: phylink_disconnect_phy() pl->netdev->phydev = NULL; phy_disconnect() phy_detach() phydev->attached_dev->phydev = NULL; This patch removes the redundant assignments, restricting manipulation of the netdev.phydev field to phy_attach_direct() and phy_detach().

Yuval Mintz says: ==================== ipmr, ip6mr: Align multicast routing for IPv4 & IPv6 Historically ip6mr was based [cut-n-paste] on ipmr and the two have not diverged too much. Apparently as ipv4 multicast routing is more common than its ipv6 brethren modifications since then are mostly one-way, affecting ipmr while leaving ip6mr unchanged. This series is meant to re-factor both ipmr and ip6mr into having common structures [and some functionality], adding 2 new common files - mroute_base.h and ipmr_base.c. The series begins by bringing ip6mr up to speed to some of the changes applied in the past to ipmr [#2, #3]. It is then possible to re-factor a lot of the common structures - vif devices [#1], mr_table [#4] mfc_cache [#6], and use the common structures in both ipmr and ip6mr. The rest of the patches re-factor some choice flows used by both ipmr and ip6mr and eliminates duplicity. This series would later allow for easy extension of ipmr offloading to support ip6mr offloading as well, as almost all structures related to the offloading would be shared between the two protocols. Changes from previous versions ------------------------------ v2: - #6 Corrected reporting logic when hitting an unresolved cache - #7 Addressed kernel doc style [Thanks Nikolay] RFC -> v1: - Corrected support for CONFIG_IP{,V6}_MROUTE_MULTIPLE_TABLES - Addressed a couple of kbuild test robot issues ==================== Signed-off-by: David S.

2018-03-01ip6mr: Align hash implementation to ipmrYuval Mintz2-159/+184
Since commit 8fb472c09b9d ("ipmr: improve hash scalability") ipmr has been using rhashtable as a basis for its mfc routes, but ip6mr is currently still using the old private MFC hash implementation. Align ip6mr to the current ipmr implementation. Signed-off-by: Yuval Mintz <yuvalm@mellanox.com> Acked-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.
