selftests: tc-testing: fix parsing of ife type

2019-01-16T22:05:42Z

In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format specifier for the ife type changed from 0x%X to %#llX, causing systematic failures in the following TDC test cases: 7682 - Create valid ife encode action with mark and pass control ef47 - Create valid ife encode action with mark and pipe control df43 - Create valid ife encode action with mark and continue control e4cf - Create valid ife encode action with mark and drop control ccba - Create valid ife encode action with mark and reclassify control a1cf - Create valid ife encode action with mark and jump control cb3d - Create valid ife encode action with mark value at 32-bit maximum 95ed - Create valid ife encode action with prio and pass control aa17 - Create valid ife encode action with prio and pipe control 74c7 - Create valid ife encode action with prio and continue control 7a97 - Create valid ife encode action with prio and drop control f66b - Create valid ife encode action with prio and reclassify control 3056 - Create valid ife encode action with prio and jump control 7dd3 - Create valid ife encode action with prio value at 32-bit maximum 05bb - Create valid ife encode action with tcindex and pass control ce65 - Create valid ife encode action with tcindex and pipe control 09cd - Create valid ife encode action with tcindex and continue control 8eb5 - Create valid ife encode action with tcindex and continue control 451a - Create valid ife encode action with tcindex and drop control d76c - Create valid ife encode action with tcindex and reclassify control e731 - Create valid ife encode action with tcindex and jump control b7b8 - Create valid ife encode action with tcindex value at 16-bit maximum 2a9c - Create valid ife encode action with mac src parameter cf5c - Create valid ife encode action with mac dst parameter 2353 - Create valid ife encode action with mac src and mac dst parameters 552c - Create valid ife encode action with mark and type parameters 0421 - Create valid ife encode action with prio and type parameters 4017 - Create valid ife encode action with tcindex and type parameters fac3 - Create valid ife encode action with index at 32-bit maximnum 7c25 - Create valid ife decode action with pass control dccb - Create valid ife decode action with pipe control 7bb9 - Create valid ife decode action with continue control d9ad - Create valid ife decode action with drop control 219f - Create valid ife decode action with reclassify control 8f44 - Create valid ife decode action with jump control b330 - Create ife encode action with cookie Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass both with old and new tc binaries. While at it, fix a small typo in test case fac3 ('maximnum'->'maximum'). Signed-off-by: Davide Caratti Acked-by: Stephen Hemminger Signed-off-by: David S. Miller

selftests: tc-testing: fix tunnel_key failure if dst_port is unspecified

2019-01-16T05:58:17Z

After commit 1c25324caf82 ("net/sched: act_tunnel_key: Don't dump dst port if it wasn't set"), act_tunnel_key doesn't dump anymore the destination port, unless it was explicitly configured. This caused systematic failures in the following TDC test case: 7a88 - Add tunnel_key action with cookie parameter Avoid matching zero values of TCA_TUNNEL_KEY_ENC_DST_PORT to let the test pass again.

selftests: tc-testing: drop test on missing tunnel key id

2019-01-16T05:55:50Z

After merge of commit 80ef0f22ceda ("net/sched: act_tunnel_key: Allow key-less tunnels"), act_tunnel_key does not reject anymore requests to install 'set' rules where the key id is missing. Therefore, drop the following TDC testcase: ba4e - Add tunnel_key set action with missing mandatory id parameter because it's going to become a systematic fail as soon as userspace iproute2 will start supporting key-less tunnels.

Pull networking updates from David Miller: 1) New ipset extensions for matching on destination MAC addresses, from Stefano Brivio. 2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to nfp driver. From Stefano Brivio. 3) Implement GRO for plain UDP sockets, from Paolo Abeni. 4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT bit so that we could support the entire vlan_tci value. 5) Rework the IPSEC policy lookups to better optimize more usecases, from Florian Westphal. 6) Infrastructure changes eliminating direct manipulation of SKB lists wherever possible, and to always use the appropriate SKB list helpers. This work is still ongoing... 7) Lots of PHY driver and state machine improvements and simplifications, from Heiner Kallweit. 8) Various TSO deferral refinements, from Eric Dumazet. 9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov. 10) Batch dropping of XDP packets in tuntap, from Jason Wang. 11) Lots of cleanups and improvements to the r8169 driver from Heiner Kallweit, including support for ->xmit_more. This driver has been getting some much needed love since he started working on it. 12) Lots of new forwarding selftests from Petr Machata. 13) Enable VXLAN learning in mlxsw driver, from Ido Schimmel. 14) Packed ring support for virtio, from Tiwei Bie. 15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov. 16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu. 17) Implement coalescing on TCP backlog queue, from Eric Dumazet. 18) Implement carrier change in tun driver, from Nicolas Dichtel. 19) Support msg_zerocopy in UDP, from Willem de Bruijn. 20) Significantly improve garbage collection of neighbor objects when the table has many PERMANENT entries, from David Ahern. 21) Remove egdev usage from nfp and mlx5, and remove the facility completely from the tree as it no longer has any users. From Oz Shlomo and others. 22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and therefore abort the operation before the commit phase (which is the NETDEV_CHANGEADDR event). From Petr Machata. 23) Add indirect call wrappers to avoid retpoline overhead, and use them in the GRO code paths. From Paolo Abeni. 24) Add support for netlink FDB get operations, from Roopa Prabhu. 25) Support bloom filter in mlxsw driver, from Nir Dotan. 26) Add SKB extension infrastructure. This consolidates the handling of the auxiliary SKB data used by IPSEC and bridge netfilter, and is designed to support the needs to MPTCP which could be integrated in the future. 27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1845 commits) net: dccp: fix kernel crash on module load drivers/net: appletalk/cops: remove redundant if statement and mask bnx2x: Fix NULL pointer dereference in bnx2x_del_all_vlans() on some hw net/net_namespace: Check the return value of register_pernet_subsys() net/netlink_compat: Fix a missing check of nla_parse_nested ieee802154: lowpan_header_create check must check daddr net/mlx4_core: drop useless LIST_HEAD mlxsw: spectrum: drop useless LIST_HEAD net/mlx5e: drop useless LIST_HEAD iptunnel: Set tun_flags in the iptunnel_metadata_reply from src net/mlx5e: fix semicolon.cocci warnings staging: octeon: fix build failure with XFRM enabled net: Revert recent Spectre-v1 patches. can: af_can: Fix Spectre v1 vulnerability packet: validate address length if non-zero nfc: af_nfc: Fix Spectre v1 vulnerability phonet: af_phonet: Fix Spectre v1 vulnerability net: core: Fix Spectre v1 vulnerability net: minor cleanup in skb_ext_add() net: drop the unused helper skb_ext_get() ...

selftests: Fix test errors related to lib.mk khdr target

2018-12-13T23:51:30Z

Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") added khdr target to run headers_install target from the main Makefile. The logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize variables and include files to run headers_install from the top level Makefile. There are a few problems with this logic. 1. Exposes top_srcdir to all tests 2. Common logic impacts all tests 3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in some cases, and STATIC_LIBS in other cases. This makes this framework confusing to use. The common logic that runs for all tests even when KSFT_KHDR_INSTALL isn't defined by the test. top_srcdir is initialized to a default value when test doesn't initialize it. It works for all tests without a sub-dir structure and tests with sub-dir structure fail to build. e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make: *** No rule to make target '../../../../scripts/subarch.include'. Stop. There is no reason to require all tests to define top_srcdir and there is no need to require tests to add khdr dependency using adhoc changes to TEST_* and other variables. Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests that have the dependency on headers_install. Change common logic to include khdr target define and "all" target with dependency on khdr when KSFT_KHDR_INSTALL is defined. Only tests that have dependency on headers_install have to define just the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to specify khdr dependency in the test Makefiles.
