2022-03-03selftests: mlxsw: resource_scale: Fix return valueAmit Cohen1-1/+1
The test runs several test cases and is supposed to return an error in case at least one of them failed. Currently, the check of the return value of each test case is in the wrong place, which can result in the wrong return value. For example: # TESTS='tc_police' ./resource_scale.sh TEST: 'tc_police' [default] 968 [FAIL] tc police offload count failed Error: mlxsw_spectrum: Failed to allocate policer index. We have an error talking to the kernel Command failed /tmp/tmp.i7Oc5HwmXY:969 TEST: 'tc_police' [default] overflow 969 [ OK ] ... TEST: 'tc_police' [ipv4_max] overflow 969 [ OK ] $ echo $? 0 Fix this by moving the check to be done after each test case.

2022-03-03libbpf: Add a check to ensure that page_cnt is non-zeroYuntao Wang1-2/+2
The page_cnt parameter is used to specify the number of memory pages allocated for each per-CPU buffer, it must be non-zero and a power of 2. Currently, the __perf_buffer__new() function attempts to validate that the page_cnt is a power of 2 but forgets checking for the case where page_cnt is zero, we can fix it by replacing 'page_cnt & (page_cnt - 1)' with 'page_cnt == 0 || (page_cnt & (page_cnt - 1))'. If so, we also don't need to add a check in perf_buffer__new_v0_6_0() to make sure that page_cnt is non-zero and the check for zero in perf_buffer__new_raw_v0_6_0() can also be removed. The code will be cleaner and more readable. Signed-off-by: Yuntao Wang <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
2022-03-03bpf: selftests: test skb->tstamp in redirect_neighMartin KaFai Lau2-0/+783
This patch adds tests on forwarding the delivery_time for the following cases - tcp/udp + ip4/ip6 + bpf_redirect_neigh - tcp/udp + ip4/ip6 + ip[6]_forward - bpf_skb_set_delivery_time - The old rcv timestamp expectation on tc-bpf@ingress Signed-off-by: Martin KaFai Lau <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-03-03bpf: Add __sk_buff->delivery_time_type and bpf_skb_set_skb_delivery_time()Martin KaFai Lau1-1/+40
* __sk_buff->delivery_time_type: This patch adds __sk_buff->delivery_time_type. It tells if the delivery_time is stored in __sk_buff->tstamp or not. It will be most useful for ingress to tell if the __sk_buff->tstamp has the (rcv) timestamp or delivery_time. If delivery_time_type is 0 (BPF_SKB_DELIVERY_TIME_NONE), it has the (rcv) timestamp. Two non-zero types are defined for the delivery_time_type, BPF_SKB_DELIVERY_TIME_MONO and BPF_SKB_DELIVERY_TIME_UNSPEC. For UNSPEC, it can only happen in egress because only mono delivery_time can be forwarded to ingress now. The clock of UNSPEC delivery_time can be deduced from the skb->sk->sk_clockid which is how the sch_etf doing it also. * Provide forwarded delivery_time to tc-bpf@ingress: With the help of the new delivery_time_type, the tc-bpf has a way to tell if the __sk_buff->tstamp has the (rcv) timestamp or the delivery_time. During bpf load time, the verifier will learn if the bpf prog has accessed the new __sk_buff->delivery_time_type. If it does, it means the tc-bpf@ingress is expecting the skb->tstamp could have the delivery_time. The kernel will then read the skb->tstamp as-is during bpf insn rewrite without checking the skb->mono_delivery_time. This is done by adding a new prog->delivery_time_access bit. The same goes for writing skb->tstamp. * bpf_skb_set_delivery_time(): The bpf_skb_set_delivery_time() helper is added to allow setting both delivery_time and the delivery_time_type at the same time. If the tc-bpf does not need to change the delivery_time_type, it can directly write to the __sk_buff->tstamp as the existing tc-bpf has already been doing. It will be most useful at ingress to change the __sk_buff->tstamp from the (rcv) timestamp to a mono delivery_time and then bpf_redirect_*(). bpf only has mono clock helper (bpf_ktime_get_ns), and the current known use case is the mono EDT for fq, and only mono delivery time can be kept during forward now, so bpf_skb_set_delivery_time() only supports setting BPF_SKB_DELIVERY_TIME_MONO. It can be extended later when use cases come up and the forwarding path also supports other clock bases. Signed-off-by: Martin KaFai Lau <[email protected]> Signed-off-by: David S.

2022-03-01KVM: selftests: Add test to verify KVM handling of ICRSean Christopherson4-0/+153
The main thing that the selftest verifies is that KVM copies x2APIC's ICR[63:32] to/from ICR2 when userspace accesses the vAPIC page via KVM_{G,S}ET_LAPIC. KVM previously split x2APIC ICR to ICR+ICR2 at the time of write (from the guest), and so KVM must preserve that behavior for backwards compatibility between different versions of KVM. It will also test other invariants, e.g. that KVM clears the BUSY flag on ICR writes, that the reserved bits in ICR2 are dropped on writes from the guest, etc...

Because the OUTPUT variable ends with a slash but CURDIR doesn't, to keep the _OUTPUT value consistent, we add a trailing slash to CURDIR when defining _OUTPUT variable. Since the _OUTPUT variable holds a value ending with a trailing slash, there is no need to add another one when defining BOOTSTRAP_OUTPUT and LIBBPF_OUTPUT variables. Likewise, when defining LIBBPF_INCLUDE and LIBBPF_BOOTSTRAP_INCLUDE, we shouldn't add an extra slash either for the same reason. When building libbpf, the value of the DESTDIR argument should also not end with a trailing slash.

Currently, --entries uses -e as the short version in the hist mode of timerlat and osnoise tools. But as -e is already used to enable events on trace sessions by other tools, thus let's keep it available for the same usage for all rtla tools. Make -E the short version of --entries for hist mode on all tools. Note: rtla was merged in this merge window, so rtla was not released yet.

2022-02-25selftests/rtc: continuously read RTC in a loop for 30sMateusz Jończyk2-1/+67
Some problems with reading the RTC time may happen rarely, for example while the RTC is updating. So read the RTC many times to catch these problems. For example, a previous attempt for my commit ea6fa4961aab ("rtc: mc146818-lib: fix RTC presence check") was incorrect and would have triggered this selftest. To avoid the risk of damaging the hardware, wait 11ms before consecutive reads. In rtc_time_to_timestamp I copied values manually instead of casting - just to be on the safe side. The 11ms wait period was chosen so that it is not a divisor of 1000ms.

2022-02-25KVM: selftests: aarch64: Skip tests if we can't create a vgic-v3Mark Brown3-2/+13
The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.

2022-02-23bpftool: Bpf skeletons assert type sizesDelyan Kratunov1-22/+105
When emitting type declarations in skeletons, bpftool will now also emit static assertions on the size of the data/bss/rodata/etc fields. This ensures that in situations where userspace and kernel types have the same name but differ in size we do not silently produce incorrect results but instead break the build. This was reported in [1] and as expected the repro in [2] fails to build on the new size assert after this change.
