2017-09-29bpf: Swap the order of checking prog_info and map_infoMartin KaFai Lau1-28/+30
This patch swaps the checking order. It now checks the map_info first and then prog_info. It is a prep work for adding test to the newly added fields (the map_ids of prog_info field in particular).

2017-09-29bpf: libbpf: Provide basic API support to specify BPF obj nameMartin KaFai Lau1-1/+1
This patch extends the libbpf to provide API support to allow specifying BPF object name. In tools/lib/bpf/libbpf, the C symbol of the function and the map is used. Regarding section name, all maps are under the same section named "maps". Hence, section name is not a good choice for map's name. To be consistent with map, bpf_prog also follows and uses its function symbol as the prog's name. This patch adds logic to collect function's symbols in libbpf. There is existing codes to collect the map's symbols and no change is needed. The bpf_load_program_name() and bpf_map_create_name() are added to take the name argument. For the other bpf_map_create_xxx() variants, a name argument is directly added to them. In samples/bpf, bpf_load.c in particular, the symbol is also used as the map's name and the map symbols has already been collected in the existing code. For bpf_prog, bpf_load.c does not collect the function symbol name. We can consider to collect them later if there is a need to continue supporting the bpf_load.c.

2017-09-26bpf: improve selftests and add tests for meta pointerDaniel Borkmann5-4/+370
Add various test_verifier selftests, and a simple xdp/tc functional test that is being attached to veths. Also let new versions of clang use the recently added -mcpu=probe support [1] for the BPF target, so that it can probe the underlying kernel for BPF insn set extensions. We could also just set this options always, where older versions just ignore it and give a note to the user that the -mcpu value is not supported, but given emitting the note cannot be turned off from clang side lets not confuse users running selftests with it, thus fallback to the default generic one when we see that clang doesn't support it. Also allow CPU option to be overridden in the Makefile from command line.

2017-09-25selftests: timers: set-timer-lat: Fix hang when testing unsupported alarmsShuah Khan1-3/+6
When timer_create() fails on a bootime or realtime clock, setup_timer() returns 0 as if timer has been set. Callers wait forever for the timer to expire. This hang is seen on a system that doesn't have support for: CLOCK_REALTIME_ALARM ABSTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] Test hangs waiting for a timer that hasn't been set to expire. Fix setup_timer() to return 1, add handling in callers to detect the unsupported case and return 0 without waiting to not fail the test. Signed-off-by: Shuah Khan <[email protected]>
2017-09-25selftests: timers: set-timer-lat: fix hang when std out/err are redirectedShuah Khan1-3/+1
do_timer_oneshot() uses select() as a timer with FD_SETSIZE and readfs is cleared with FD_ZERO without FD_SET. When stdout and stderr are redirected, the test hangs in select forever. Fix the problem calling select() with readfds empty and nfds zero. This is sufficient for using select() for timer. With this fix "./set-timer-lat > /dev/null 2>&1" no longer hangs.

2017-09-21samples/bpf: Fix pt_regs issues when cross-compilingJoel Fernandes1-7/+49
BPF samples fail to build when cross-compiling for ARM64 because of incorrect pt_regs param selection. This is because clang defines __x86_64__ and bpf_headers thinks we're building for x86. Since clang is building for the BPF target, it shouldn't make assumptions about what target the BPF program is going to run on. To fix this, lets pass ARCH so the header knows which target the BPF program is being compiled for and can use the correct pt_regs code.

2017-09-19bpf: Add uniqueness invariant to trivial lpm test implementationCraig Gallek1-1/+13
The 'trivial' lpm implementation in this test allows equivalent nodes to be added (that is, nodes consisting of the same prefix and prefix length). For lookup operations, this is fine because insertion happens at the head of the (singly linked) list and the first, best match is returned. In order to support deletion, the tlpm data structue must first enforce uniqueness. This change modifies the insertion algorithm to search for equivalent nodes and remove them. Note: the BPF_MAP_TYPE_LPM_TRIE already has a uniqueness invariant that is implemented as node replacement.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull namespace updates from Eric Biederman: "Life has been busy and I have not gotten half as much done this round as I would have liked. I delayed it so that a minor conflict resolution with the mips tree could spend a little time in linux-next before I sent this pull request. This includes two long delayed user namespace changes from Kirill Tkhai. It also includes a very useful change from Serge Hallyn that allows the security capability attribute to be used inside of user namespaces. The practical effect of this is people can now untar tarballs and install rpms in user namespaces. It had been suggested to generalize this and encode some of the namespace information information in the xattr name. Upon close inspection that makes the things that should be hard easy and the things that should be easy more expensive. Then there is my bugfix/cleanup for signal injection that removes the magic encoding of the siginfo union member from the kernel internal si_code. The mips folks reported the case where I had used FPE_FIXME me is impossible so I have remove FPE_FIXME from mips, while at the same time including a return statement in that case to keep gcc from complaining about unitialized variables. I almost finished the work to get make copy_siginfo_to_user a trivial copy to user. The code is available at: git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3 But I did not have time/energy to get the code posted and reviewed before the merge window opened.

2017-09-08bpf: add support for sockmap detach programsJohn Fastabend1-1/+50
The bpf map sockmap supports adding programs via attach commands. This patch adds the detach command to keep the API symmetric and allow users to remove previously added programs. Otherwise the user would have to delete the map and re-add it to get in this state. This also adds a series of additional tests to capture detach operation and also attaching/detaching invalid prog types. API note: socks will run (or not run) programs depending on the state of the map at the time the sock is added. We do not for example walk the map and remove programs from previously attached socks.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Nothing really major this release, despite quite a lot of activity. Just lots of things all over the place. Some things of note include: - Access via perf to a new type of PMU (IMC) on Power9, which can count both core events as well as nest unit events (Memory controller etc). - Optimisations to the radix MMU TLB flushing, mostly to avoid unnecessary Page Walk Cache (PWC) flushes when the structure of the tree is not changing. - Reworks/cleanups of do_page_fault() to modernise it and bring it closer to other architectures where possible. - Rework of our page table walking so that THP updates only need to send IPIs to CPUs where the affected mm has run, rather than all CPUs. - The size of our vmalloc area is increased to 56T on 64-bit hash MMU systems. This avoids problems with the percpu allocator on systems with very sparse NUMA layouts. - STRICT_KERNEL_RWX support on PPC32. - A new sched domain topology for Power9, to capture the fact that pairs of cores may share an L2 cache. - Power9 support for VAS, which is a new mechanism for accessing coprocessors, and initial support for using it with the NX compression accelerator. - Major work on the instruction emulation support, adding support for many new instructions, and reworking it so it can be used to implement the emulation needed to fixup alignment faults. - Support for guests under PowerVM to use the Power9 XIVE interrupt controller. And probably that many things again that are almost as interesting, but I had to keep the list short. Plus the usual fixes and cleanups as always.

2017-09-06selftests/memfd: add memfd_create hugetlbfs selftestMike Kravetz3-86/+357
With the addition of hugetlbfs support in memfd_create, the memfd selftests should verify correct functionality with hugetlbfs. Instead of writing a separate memfd hugetlbfs test, modify the memfd_test program to take an optional argument 'hugetlbfs'. If the hugetlbfs argument is specified, basic memfd_create functionality will be exercised on hugetlbfs. If hugetlbfs is not specified, the current functionality of the test is unchanged. Note that many of the tests in memfd_test test file sealing operations. hugetlbfs does not support file sealing, therefore for hugetlbfs all sealing related tests are skipped. In order to test on hugetlbfs, there needs to be preallocated huge pages. A new script (run_tests) is added. This script will first run the existing memfd_create tests. It will then, attempt to allocate the required number of huge pages before running the hugetlbfs test. At the end of testing, it will release any huge pages allocated for testing purposes.
