2018-07-01tools: libbpf: restore the ability to load programs from .text sectionJakub Kicinski
libbpf used to be able to load programs from the default section called '.text'. It's not very common to leave sections unnamed, but if it happens libbpf will fail to load the programs reporting -EINVAL from the kernel. The -EINVAL comes from bpf_obj_name_cpy() because since 48cca7e44f9f ("libbpf: add support for bpf_call") libbpf does not resolve program names for programs in '.text', defaulting to '.text'. '.text', however, does not pass the (isalnum(*src) || *src == '_') check in bpf_obj_name_cpy(). With few extra lines of code we can limit the pseudo call assumptions only to objects which actually contain code relocations.

2018-07-01tools: bpftool: use correct make variable type to improve compilation timeJakub Kicinski
Commit 4bfe3bd3cc35 ("tools/bpftool: use version from the kernel source tree") added version to bpftool. The version used is equal to the kernel version and obtained by running make kernelversion against kernel source tree. Version is then communicated to the sources with a command line define set in CFLAGS. Use a simply expanded variable for the version, otherwise the recursive make will run every time CFLAGS are used. This brings the single-job compilation time for me from almost 16 sec down to less than 4 sec.

Pull block fixes from Jens Axboe: "Small set of fixes for this series. Mostly just minor fixes, the only oddball in here is the sg change. The sg change came out of the stall fix for NVMe, where we added a mempool and limited us to a single page allocation. CONFIG_SG_DEBUG sort-of ruins that, since we'd need to account for that. That's actually a generic problem, since lots of drivers need to allocate SG lists. So this just removes support for CONFIG_SG_DEBUG, which I added back in 2007 and to my knowledge it was never useful.

2018-06-30tools/testing/nvdimm: advertise a write cache for nfit_testVishal Verma
Commit 546eb0317cfa "libnvdimm, pmem: Do not flush power-fail protected CPU caches" fixed the write_cache detection to correctly show the lack of a write cache based on the platform capabilities described in the ACPI NFIT. The nfit_test unit tests expected a write cache to be present, so change the nfit test namespaces to only advertise a persistence domain limited to the memory controller. This allows the kernel to show a write_cache attribute, and the test behaviour remains unchanged.

2018-06-30selftests: forwarding: lib: Parameterize NUM_NETIFS in two functionsPetr Machata
setup_wait() and tc_offload_check() both assume that all NUM_NETIFS interfaces are relevant for a given test. However, the scale test script acts as an umbrella for a number of sub-tests, some of which may not require all the interfaces. Thus it's suboptimal for tc_offload_check() to query all the interfaces. In case of setup_wait() it's incorrect, because the sub-test in question of course doesn't configure any interfaces beyond what it needs, and setup_wait() then ends up waiting indefinitely for the extraneous interfaces to come up. For that reason, give setup_wait() and tc_offload_check() an optional parameter with a number of interfaces to probe. Fall back to global NUM_NETIFS if the parameter is not given.

There are several cases where traffic that would normally be forwarded in silicon needs to be observed in slow path. That's achieved by trapping such traffic, and the functions trap_install() and trap_uninstall() realize that.

2018-06-26selftests: bpf: add missing NET_SCHED to configAnders Roxell
CONFIG_NET_SCHED wasn't enabled in arm64's defconfig only for x86. So bpf/test_tunnel.sh tests fails with: RTNETLINK answers: Operation not supported RTNETLINK answers: Operation not supported We have an error talking to the kernel, -1 Enable NET_SCHED and more tests pass.

2018-06-26selftests: forwarding: Test routed bridge interfacePetr Machata
Add test for cases where bridge itself acts as a router interface, with front panel port attached to the bridge in question. In the first test (router_bridge.sh), VLAN memberships are not configured in any way, and everything uses default PVID of 1. Thus traffic in $h1 and $h2 is untagged. This test ensures that the previous patches didn't break a currently working scenario. In the second test (router_bridge_vlan.sh), a VLAN 555 pvid untagged is added to the bridge CPU port, with that VLAN leaving the bridge tagged through its sole member port. The traffic is therefore expected to come out tagged at $h1. This tests the fix introduced in the previous patches.
