2019-05-24libbpf: add btf__parse_elf API to load .BTF and .BTF.extAndrii Nakryiko
Loading BTF and BTF.ext from ELF file is a common need. Instead of requiring every user to re-implement it, let's provide this API from libbpf itself. It's mostly copy/paste from `bpftool btf dump` implementation, which will be switched to libbpf's version in next patch. btf__parse_elf allows to load BTF and optionally BTF.ext. This is also useful for tests that need to load/work with BTF, loaded from test ELF files. Signed-off-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>

Jose Abreu says: ==================== net: stmmac: Improvements and Selftests [ Thanks to the introducion of selftests this series ended up being a misc of improvements and the selftests additions per-se. ] This introduces selftests support in stmmac driver. We add 9 basic sanity checks and MAC loopback support for all cores within the driver. This way more tests can easily be added in the future and can be run in virtually any MAC/GMAC/QoS/XGMAC platform. Having this we can find regressions and missing features in the driver while at the same time we can check if the IP is correctly working. We have been using this for some time now and I do have more tests to submit in the feature. My experience is that although writing the tests adds more development time, the gain results are obvious. I let this feature optional within the driver under a Kconfig option. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

When we trigger NAPI we are disabling interrupts but in case we receive or send a packet in the meantime, as interrupts are disabled, we will miss this event. Trigger both NAPI instances (RX and TX) when at least one event happens so that we don't miss any interrupts.

2019-05-24selftests/net: SO_TXTIME with ETF and FQWillem de Bruijn
The SO_TXTIME API enables packet tranmission with delayed delivery. This is currently supported by the ETF and FQ packet schedulers. Evaluate the interface with both schedulers. Install the scheduler and send a variety of packets streams: without delay, with one delayed packet, with multiple ordered delays and with reordering. Verify that packets are released by the scheduler in expected order. The ETF qdisc requires a timestamp in the future on every packet. It needs a delay on the qdisc else the packet is dropped on dequeue for having a delivery time in the past. The test value is experimentally derived. ETF requires clock_id CLOCK_TAI. It checks this base and drops for non-conformance. The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP as of commit fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC"). Within a flow there is an expecation of ordered delivery, as shown by delivery times of test 4. The FQ qdisc does not require all packets to have timestamps and does not drop for non-conformance. The large (msec) delays are chosen to avoid flakiness. Output: SO_TXTIME ipv6 clock monotonic payload:a delay:28 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:38 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:40 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:33 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:10120 expected:10000 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:10102 expected:10000 (us) [.. etc ..] OK.

2019-05-24net: sched: don't use tc_action->order during action dumpVlad Buslov
Function tcf_action_dump() relies on tc_action->order field when starting nested nla to send action data to userspace. This approach breaks in several cases: - When multiple filters point to same shared action, tc_action->order field is overwritten each time it is attached to filter. This causes filter dump to output action with incorrect attribute for all filters that have the action in different position (different order) from the last set tc_action->order value. - When action data is displayed using tc action API (RTM_GETACTION), action order is overwritten by tca_action_gd() according to its position in resulting array of nl attributes, which will break filter dump for all filters attached to that shared action that expect it to have different order value. Don't rely on tc_action->order when dumping actions. Set nla according to action position in resulting array of actions instead.

'ipv6-Move-exceptions-to-fib6_nh-and-make-it-optional-in-a-fib6_info' David Ahern says: ==================== ipv6: Move exceptions to fib6_nh and make it optional in a fib6_info Patches 1 and 4 move pcpu and exception caches from fib6_info to fib6_nh. With respect to the current FIB entries this is only a movement from one struct to another contained within the first. Patch 2 refactors the core logic of fib6_drop_pcpu_from into a helper that is invoked per fib6_nh. Patch 3 refactors exception handling in a similar way - creating a bunch of helpers that can be invoked per fib6_nh with the goal of making patch 4 easier to review as well as creating the code needed for nexthop objects. Patch 5 makes a fib6_nh at the end of a fib6_info an array similar to IPv4 and its fib_info. For the current fib entry model, all fib6_info will have a fib6_nh allocated for it. Patch 6 refactors ip6_route_del moving the code for deleting an exception entry into a new function. Patch 7 adds tests for redirect route exceptions. The new test was written against 5.1 (before any of the nexthop refactoring). It and the pmtu.sh selftest exercise the exception code paths - from creating exceptions to cleaning them up on device delete. All tests pass without any rcu locking or memleak warnings. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-05-24ipv6: Move exception bucket to fib6_nhDavid Ahern
Similar to the pcpu routes exceptions are really per nexthop, so move rt6i_exception_bucket from fib6_info to fib6_nh. To avoid additional increases to the size of fib6_nh for a 1-bit flag, use the lowest bit in the allocated memory pointer for the flushed flag. Add helpers for retrieving the bucket pointer to mask off the flag. The cleanup of the exception bucket is moved to fib6_nh_release. fib6_nh_flush_exceptions can now be called from 2 contexts: 1. deleting a fib entry 2. deleting a fib6_nh For 1., fib6_nh_flush_exceptions is called for a specific fib6_info that is getting deleted. All exceptions in the cache using the entry are deleted. For 2, the fib6_nh itself is getting destroyed so fib6_nh_flush_exceptions is called for a NULL fib6_info which means flush all entries. The pmtu.sh selftest exercises the affected code paths - from creating exceptions to cleaning them up on device delete. All tests pass without any rcu locking or memleak warnings.

In all 3 cases, move the primary logic into a new helper that starts with fib6_nh_. The latter 3 functions still take a fib6_info; this will be changed to fib6_nh in the next patch. In the case of rt6_mtu_change_route, move the fib6_metric_locked out as a standalone check - no need to call the new function if the fib entry has the mtu locked. Also, add fib6_info to rt6_mtu_change_arg as a way of passing the fib entry to the new helper. No functional change intended.

If the passed in 'from' is non-NULL then only entries associated with that fib6_info are removed (e.g., case where fib entry is deleted); if the 'from' is NULL are entries are flushed (e.g., fib6_nh is deleted).

2019-05-24ipv6: Move pcpu cached routes to fib6_nhDavid Ahern
rt6_info are specific instances of a fib entry and are tied to a device and gateway - ie., a nexthop. Before nexthop objects, IPv6 fib entries have separate fib6_info for each nexthop in a multipath route, so the location of the pcpu cache in the fib6_info struct worked. However, with nexthop objects a fib6_info can point to a set of nexthops (yet another alignment of ipv6 with ipv4). Accordingly, the pcpu cache needs to be moved to the fib6_nh struct so the cached entries are local to the nexthop specification used to create the rt6_info. Initialization and free of the pcpu entries moved to fib6_nh_init and fib6_nh_release. Change in location only, from fib6_info down to fib6_nh; no other functional change intended.

Because the RX BD ring dynamic allocation has not been supported and it is too expensive to use extended RX BDs if timestamping is not used, a Kconfig option is used to enable extended RX BDs in order to support hardware timestamping. This option will be removed once RX BD ring dynamic allocation is implemented.

2019-05-24net: fec: fix the clk mismatch in failed_reset pathAndy Duan
Fix the clk mismatch in the error path "failed_reset" because below error path will disable clk_ahb and clk_ipg directly, it should use pm_runtime_put_noidle() instead of pm_runtime_put() to avoid to call runtime resume callback.

Commit 11988499e62b ("KVM: x86: Skip EFER vs. guest CPUID checks for host-initiated writes", 2019-04-02) introduced a "return false" in a function returning int, and anyway set_efer has a "nonzero on error" conventon so it should be returning 1.

2019-05-24selftests: rtc: rtctest: specify timeoutsAlexandre Belloni
uie_read is a commonly failing test that will block forever on buggy rtc drivers. Shorten its timeout so it fails earlier. Also increase the timeout for the two alarm test on a minute boundary.

2019-05-24selftests/harness: Allow test to configure timeoutAlexandre Belloni
Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test") adds an hardcoded 30s timeout to all tests. Unfortunately, rtctest has two tests taking up to 60s. Allow for individual tests to define their own timeout.

2019-05-24tools/kvm_stat: fix fields filter for child eventsStefan Raspl
The fields filter would not work with child fields, as the respective parents would not be included. No parents displayed == no childs displayed. To reproduce, run on s390 (would work on other platforms, too, but would require a different filter name): - Run 'kvm_stat -d' - Press 'f' - Enter 'instruct' Notice that events like instruction_diag_44 or instruction_diag_500 are not displayed - the output remains empty. With this patch, we will filter by matching events and their parents. However, consider the following example where we filter by instruction_diag_44: kvm statistics - summary regex filter: instruction_diag_44 Event Total %Total CurAvg/s exit_instruction 276 100.0 12 instruction_diag_44 256 92.8 11 Total 276 12 Note that the parent ('exit_instruction') displays the total events, but the childs listed do not match its total (256 instead of 276). This is intended (since we're filtering all but one child), but might be confusing on first sight. Signed-off-by: Stefan Raspl <raspl@linux.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
