2020-03-13selftests/bpf: Guarantee that useep() calls nanosleep() syscallAndrii Nakryiko
Some implementations of C runtime library won't call nanosleep() syscall from usleep(). But a bunch of kprobe/tracepoint selftests rely on nanosleep being called to trigger them. To make this more reliable, "override" usleep implementation and call nanosleep explicitly.

2020-03-12xarray: Fix early termination of xas_for_each_markedMatthew Wilcox (Oracle)
xas_for_each_marked() is using entry == NULL as a termination condition of the iteration. When xas_for_each_marked() is used protected only by RCU, this can however race with xas_store(xas, NULL) in the following way: TASK1 TASK2 page_cache_delete() find_get_pages_range_tag() xas_for_each_marked() xas_find_marked() off = xas_find_chunk() xas_store(&xas, NULL) xas_init_marks(&xas); ... rcu_assign_pointer(*slot, NULL); entry = xa_entry(off); And thus xas_for_each_marked() terminates prematurely possibly leading to missed entries in the iteration (translating to missing writeback of some pages or a similar problem). If we find a NULL entry that has been marked, skip it (unless we're trying to allocate an entry).

This commit adds a test to check if we can fully utilize 4-tuples for connect() when all ephemeral ports are exhausted. The test program changes the local port range to use only one port and binds two sockets with or without SO_REUSEADDR and SO_REUSEPORT, and with the same EUID or with different EUIDs, then do listen(). We should be able to bind only one socket having both SO_REUSEADDR and SO_REUSEPORT per EUID, which restriction is to prevent unintentional listen().

For the last time, I screwed up my ktest config file, and the build went into the default "randconfig", blowing away the .config that I had set up. The reason for the default randconfig was because when this was first written, I wanted to do a bunch of randconfigs. But as time progressed, ktest isn't about randconfig anymore, and because randconfig destroys the config in the build directory, it's a dangerous default to have. Use oldconfig as the default.

The existing tests attempt to check that JMP32 JSET ignores the upper bits in the operand registers. However, the tests missed one such bug in the x32 JIT that is only uncovered when a previous instruction pollutes the upper 32 bits of the registers. This patch adds a new test case that catches the bug by first executing a 64-bit JSET to pollute the upper 32-bits of the temporary registers, followed by a 32-bit JSET which should ignore the upper 32 bits.

Currently the SW-datapath ETS selftests use "ip link" stats to obtain the number of packets that went through a given band. mlxsw then uses ethtool per-priority counters. Instead, change both to use qdiscs. In SW datapath this is the obvious choice, and now that mlxsw offloads FIFO, this should work on the offloaded datapath as well.

2020-03-04seccomp: allow TSYNC and USER_NOTIF togetherTycho Andersen
The restriction introduced in 7a0df7fbc145 ("seccomp: Make NEW_LISTENER and TSYNC flags exclusive") is mostly artificial: there is enough information in a seccomp user notification to tell which thread triggered a notification. The reason it was introduced is because TSYNC makes the syscall return a thread-id on failure, and NEW_LISTENER returns an fd, and there's no way to distinguish between these two cases (well, I suppose the caller could check all fds it has, then do the syscall, and if the return value was an fd that already existed, then it must be a thread id, but bleh). Matthew would like to use these two flags together in the Chrome sandbox which wants to use TSYNC for video drivers and NEW_LISTENER to proxy syscalls. So, let's fix this ugliness by adding another flag, TSYNC_ESRCH, which tells the kernel to just return -ESRCH on a TSYNC error. This way, NEW_LISTENER (and any subsequent seccomp() commands that want to return positive values) don't conflict with each other.

2020-03-02selftests/bpf: Declare bpf_log_buf variables as staticToke Høiland-Jørgensen
The cgroup selftests did not declare the bpf_log_buf variable as static, leading to a linker error with GCC 10 (which defaults to -fno-common). Fix this by adding the missing static declarations.

Move BPF_PROG, BPF_KPROBE, and BPF_KRETPROBE macro into libbpf's bpf_tracing.h header to make it available for non-selftests users.

2020-03-02selftests/bpf: Fix BPF_KRETPROBE macro and use it in attach_probe testAndrii Nakryiko
For kretprobes, there is no point in capturing input arguments from pt_regs, as they are going to be, most probably, clobbered by the time probed kernel function returns. So switch BPF_KRETPROBE to accept zero or one argument (optional return result).

Commit 68ca0fd272da ("selftest/lkdtm: Don't pollute 'git status'") introduced patterns for git to ignore files generated in tools/testing/selftests/lkdtm/ Use local .gitignore file instead of using the root one.
