2022-05-23landlock: Change landlock_add_rule(2) argument check orderingMickaël Salaün1-2/+32
This makes more sense to first check the ruleset FD and then the rule attribute. It will be useful to factor out code for other rule types. Add inval_add_rule_arguments tests, extension of empty_path_beneath_attr tests, to also check error ordering for landlock_add_rule(2).

Use the standard interface order h1, swp1, swp2, h2 that is used by the forwarding selftest framework. The previous order was confusing even with the ASCII drawing. That isn't needed anymore.

2022-05-22selftests/powerpc: Better reporting in spectre_v2Russell Currey1-9/+15
In commit f3054ffd71b5 ("selftests/powerpc: Return skip code for spectre_v2"), the spectre_v2 selftest is updated to be aware of cases where the vulnerability status reported in sysfs is incorrect, skipping the test instead. This happens because qemu can misrepresent the mitigation status of the host to the guest. If the count cache is disabled in the host, and this is correctly reported to the guest, then the guest won't apply mitigations. If the guest is then migrated to a new host where mitigations are necessary, it is now vulnerable because it has not applied mitigations. Update the selftest to report when we see excessive misses, indicative of the count cache being disabled. If software flushing is enabled, also warn that these flushes are just wasting performance.

2022-05-20selftests: Add test for timing a bind request to a port with a populated ↵Joanne Koong3-0/+122
bhash entry This test populates the bhash table for a given port with MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long a bind request on the port takes. When populating the bhash table, we create the sockets and then bind the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT are set). When timing how long a bind on the port takes, we bind on a different address without SO_REUSEPORT set. We do not set SO_REUSEPORT because we are interested in the case where the bind request does not go through the tb->fastreuseport path, which is fragile (eg tb->fastreuseport path does not work if binding with a different uid). To run the test locally, I did: * ulimit -n 65535000 * ip addr add 2001:0db8:0:f101::1 dev eth0 * ./bind_bhash_test 443 Signed-off-by: Joanne Koong <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>

This is a contrived example used for the convenience of demonstrating this issue, however, this can be applied to event selects 0x28A (OC Mode Switch) and 0x08A (L1 BTB Correction), where 0x08A could end up being denied when the event select was only set up to deny 0x28A.

hw_stats_l3.sh test is failing often for l3 stats shows less than 20 packets after 2 seconds sleep. This is happening since there is a race between the 2 seconds sleep and the netdevsim actually delivering the packets. Increase the sleep time so the packets will be delivered successfully on time.

bpf selftests can no longer be built with CFLAGS=-static with liburandom_read.so and its dependent target. Filter out -static for liburandom_read.so and its dependent target. When building statically, this leaves urandom_read relying on system-wide shared libraries.

2022-05-16kselftest/arm64: bti: force static linkingAndre Przywara1-2/+2
The "bti" selftests are built with -nostdlib, which apparently automatically creates a statically linked binary, which is what we want and need for BTI (to avoid interactions with the dynamic linker). However this is not true when building a PIE binary, which some toolchains (Ubuntu) configure as the default. When compiling btitest with such a toolchain, it will create a dynamically linked binary, which will probably fail some tests, as the dynamic linker might not support BTI: =================== TAP version 13 1..18 not ok 1 nohint_func/call_using_br_x0 not ok 2 nohint_func/call_using_br_x16 not ok 3 nohint_func/call_using_blr .... =================== To make sure we create static binaries, add an explicit -static on the linker command line. This forces static linking even if the toolchain defaults to PIE builds, and fixes btitest runs on BTI enabled machines.
