2021-11-30torture: Retry download once before giving upPaul E. McKenney1-2/+9
Currently, a transient network error can kill a run if it happens while downloading the tarball to one of the target systems. This commit therefore does a 60-second wait and then a retry. If further experience indicates, a more elaborate mechanism might be used later. Signed-off-by: Paul E. McKenney <[email protected]>

2021-11-30rcu: Remove the RCU_FAST_NO_HZ Kconfig optionPaul E. McKenney3-3/+0
All of the uses of CONFIG_RCU_FAST_NO_HZ=y that I have seen involve systems with RCU callbacks offloaded. In this situation, all that this Kconfig option does is slow down idle entry/exit with an additional allways-taken early exit. If this is the only use case, then this Kconfig option nothing but an attractive nuisance that needs to go away. This commit therefore removes the RCU_FAST_NO_HZ Kconfig option.

2021-11-30rcutorture: Add CONFIG_PREEMPT_DYNAMIC=n to tiny scenariosPaul E. McKenney5-0/+5
With CONFIG_PREEMPT_DYNAMIC=y, the kernel builds with CONFIG_PREEMPTION=y because preemption can be enabled at runtime. This prevents any tests of Tiny RCU or Tiny SRCU from running correctly. This commit therefore explicitly sets CONFIG_PREEMPT_DYNAMIC=n for those scenarios. Signed-off-by: Paul E. McKenney <[email protected]>
2021-11-30selftest/bpf/benchs: Add bpf_loop benchmarkJoanne Koong7-1/+203
Add benchmark to measure the throughput and latency of the bpf_loop call. Testing this on my dev machine on 1 thread, the data is as follows: nr_loops: 10 bpf_loop - throughput: 198.519 ± 0.155 M ops/s, latency: 5.037 ns/op nr_loops: 100 bpf_loop - throughput: 247.448 ± 0.305 M ops/s, latency: 4.041 ns/op nr_loops: 500 bpf_loop - throughput: 260.839 ± 0.380 M ops/s, latency: 3.834 ns/op nr_loops: 1000 bpf_loop - throughput: 262.806 ± 0.629 M ops/s, latency: 3.805 ns/op nr_loops: 5000 bpf_loop - throughput: 264.211 ± 1.508 M ops/s, latency: 3.785 ns/op nr_loops: 10000 bpf_loop - throughput: 265.366 ± 3.054 M ops/s, latency: 3.768 ns/op nr_loops: 50000 bpf_loop - throughput: 235.986 ± 20.205 M ops/s, latency: 4.238 ns/op nr_loops: 100000 bpf_loop - throughput: 264.482 ± 0.279 M ops/s, latency: 3.781 ns/op nr_loops: 500000 bpf_loop - throughput: 309.773 ± 87.713 M ops/s, latency: 3.228 ns/op nr_loops: 1000000 bpf_loop - throughput: 262.818 ± 4.143 M ops/s, latency: 3.805 ns/op >From this data, we can see that the latency per loop decreases as the number of loops increases. On this particular machine, each loop had an overhead of about ~4 ns, and we were able to run ~250 million loops per second.

2021-11-30KVM: SEV: Prohibit migration of a VM that has mirrorsPaolo Bonzini1-0/+37
VMs that mirror an encryption context rely on the owner to keep the ASID allocated. Performing a KVM_CAP_VM_MOVE_ENC_CONTEXT_FROM would cause a dangling ASID: 1. copy context from A to B (gets ref to A) 2. move context from A to L (moves ASID from A to L) 3. close L (releases ASID from L, B still references it) The right way to do the handoff instead is to create a fresh mirror VM on the destination first: 1. copy context from A to B (gets ref to A) [later] 2. close B (releases ref to A) 3. move context from A to L (moves ASID from A to L) 4. copy context from L to M So, catch the situation by adding a count of how many VMs are mirroring this one's encryption context.

2021-11-29wireguard: device: reset peer src endpoint when netns exitsJason A. Donenfeld1-1/+23
Each peer's endpoint contains a dst_cache entry that takes a reference to another netdev. When the containing namespace exits, we take down the socket and prevent future sockets from being created (by setting creating_net to NULL), which removes that potential reference on the netns. However, it doesn't release references to the netns that a netdev cached in dst_cache might be taking, so the netns still might fail to exit. Since the socket is gimped anyway, we can simply clear all the dst_caches (by way of clearing the endpoint src), which will release all references. However, the current dst_cache_reset function only releases those references lazily. But it turns out that all of our usages of wg_socket_clear_peer_endpoint_src are called from contexts that are not exactly high-speed or bottle-necked. For example, when there's connection difficulty, or when userspace is reconfiguring the interface. And in particular for this patch, when the netns is exiting. So for those cases, it makes more sense to call dst_release immediately. For that, we add a small helper function to dst_cache. This patch also adds a test to netns.sh from Hangbin Liu to ensure this doesn't regress.

2021-11-29wireguard: selftests: actually test for routing loopsJason A. Donenfeld1-1/+5
We previously removed the restriction on looping to self, and then added a test to make sure the kernel didn't blow up during a routing loop. The kernel didn't blow up, thankfully, but on certain architectures where skb fragmentation is easier, such as ppc64, the skbs weren't actually being discarded after a few rounds through. But the test wasn't catching this. So actually test explicitly for massive increases in tx to see if we have a routing loop. Note that the actual loop problem will need to be addressed in a different commit. Fixes: b673e24aad36 ("wireguard: socket: remove errant restriction on looping to self") Signed-off-by: Jason A.

2021-11-26af_unix: Remove UNIX_ABSTRACT() macro and test sun_path[0] instead.Kuniyuki Iwashima3-4/+2
In BSD and abstract address cases, we store sockets in the hash table with keys between 0 and UNIX_HASH_SIZE - 1. However, the hash saved in a socket varies depending on its address type; sockets with BSD addresses always have UNIX_HASH_SIZE in their unix_sk(sk)->addr->hash. This is just for the UNIX_ABSTRACT() macro used to check the address type. The difference of the saved hashes comes from the first byte of the address in the first place. So, we can test it directly. Then we can keep a real hash in each socket and replace unix_table_lock with per-hash locks in the later patch.

2021-11-26KVM: selftests: Make sure kvm_create_max_vcpus test won't hit RLIMIT_NOFILEVitaly Kuznetsov1-0/+30
With the elevated 'KVM_CAP_MAX_VCPUS' value kvm_create_max_vcpus test may hit RLIMIT_NOFILE limits: # ./kvm_create_max_vcpus KVM_CAP_MAX_VCPU_ID: 4096 KVM_CAP_MAX_VCPUS: 1024 Testing creating 1024 vCPUs, with IDs 0...1023. /dev/kvm not available (errno: 24), skipping test Adjust RLIMIT_NOFILE limits to make sure KVM_CAP_MAX_VCPUS fds can be opened. Note, raising hard limit ('rlim_max') requires CAP_SYS_RESOURCE capability which is generally not needed to run kvm selftests (but without raising the limit the test is doomed to fail anyway).

2021-11-26KVM: selftests: Avoid KVM_SET_CPUID2 after KVM_RUN in hyperv_features testVitaly Kuznetsov1-69/+71
hyperv_features's sole purpose is to test access to various Hyper-V MSRs and hypercalls with different CPUID data. As KVM_SET_CPUID2 after KVM_RUN is deprecated and soon-to-be forbidden, avoid it by re-creating test VM for each sub-test.

2021-11-26selftests: sev_migrate_tests: free all VMsPaolo Bonzini1-1/+8
Ensure that the ASID are freed promptly, which becomes more important when more tests are added to this file. Cc: Peter Gonda <[email protected]> Cc: Sean Christopherson <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>
2021-11-26selftests: fix check for circular KVM_CAP_VM_MOVE_ENC_CONTEXT_FROMPaolo Bonzini1-2/+5
KVM_CAP_VM_MOVE_ENC_CONTEXT_FROM leaves the source VM in a dead state, so migrating back to the original source VM fails the ioctl. Adjust the test. Signed-off-by: Paolo Bonzini <[email protected]>
2021-11-25selftests: tls: test for correct proto_opsJakub Kicinski1-0/+55
Previous patch fixes overriding callbacks incorrectly. Triggering the crash in sendpage_locked would be more spectacular but it's hard to get to, so take the easier path of proving this is broken and call getname. We're currently getting IPv4 socket info on an IPv6 socket. Signed-off-by: Jakub Kicinski <[email protected]>

Buf can be not zero-terminated leading to strstr() to access data beyond the intended buf[] array. Fix by forcing zero termination. Signed-off-by: Andrii Nakryiko <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]

2021-11-26selftests/bpf: Prevent misaligned memory access in get_stack_raw_tp testAndrii Nakryiko1-4/+10
Perfbuf doesn't guarantee 8-byte alignment of the data like BPF ringbuf does, so struct get_stack_trace_t can arrive not properly aligned for subsequent u64 accesses. Easiest fix is to just copy data locally. Signed-off-by: Andrii Nakryiko <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
