2021-06-14ipv4: Fix device used for dst_alloc with local routesDavid Ahern1-0/+25
Oliver reported a use case where deleting a VRF device can hang waiting for the refcnt to drop to 0. The root cause is that the dst is allocated against the VRF device but cached on the loopback device. The use case (added to the selftests) has an implicit VRF crossing due to the ordering of the FIB rules (lookup local is before the l3mdev rule, but the problem occurs even if the FIB rules are re-ordered with local after l3mdev because the VRF table does not have a default route to terminate the lookup). The end result is is that the FIB lookup returns the loopback device as the nexthop, but the ingress device is in a VRF. The mismatch causes the dst alloc against the VRF device but then cached on the loopback. The fix is to bring the trick used for IPv6 (see ip6_rt_get_dev_rcu): pick the dst alloc device based the fib lookup result but with checks that the result has a nexthop device (e.g., not an unreachable or prohibit entry).

2021-06-14KVM: selftests: Add exception handling support for aarch64Ricardo Koller4-1/+287
Add the infrastructure needed to enable exception handling in aarch64 selftests. The exception handling defaults to an unhandled-exception handler which aborts the test, just like x86. These handlers can be overridden by calling vm_install_exception_handler(vector) or vm_install_sync_handler(vector, ec). The unhandled exception reporting from the guest is done using the ucall type introduced in a previous commit, UCALL_UNHANDLED. The exception handling code is inspired on kvm-unit-tests.

2021-06-14KVM: selftests: Introduce UCALL_UNHANDLED for unhandled vector reportingRicardo Koller3-13/+9
x86, the only arch implementing exception handling, reports unhandled vectors using port IO at a specific port number. This replicates what ucall already does. Introduce a new ucall type, UCALL_UNHANDLED, for guests to report unhandled exceptions. Then replace the x86 unhandled vector exception reporting to use it instead of port IO. This new ucall type will be used in the next commits by arm64 to report unhandled vectors as well. Tested: Forcing a page fault in the ./x86_64/xapic_ipi_test halter_guest_code() shows this: $ ./x86_64/xapic_ipi_test ...

2021-06-14KVM: selftests: Complete x86_64/sync_regs_test ucallRicardo Koller1-1/+6
The guest in sync_regs_test does raw ucalls by directly accessing the ucall IO port. It makes these ucalls without setting %rdi to a `struct ucall`, which is what a ucall uses to pass messages. The issue is that if the host did a get_ucall (the receiver side), it would try to access the `struct ucall` at %rdi=0 which would lead to an error ("No mapping for vm virtual address, gva: 0x0"). This issue is currently benign as there is no get_ucall in sync_regs_test; however, that will change in the next commit as it changes the unhandled exception reporting mechanism to use ucalls. In that case, every vcpu_run is followed by a get_ucall to check if the guest is trying to report an unhandled exception. Fix this in advance by setting %rdi to a UCALL_NONE struct ucall for the sync_regs_test guest. Tested with gcc-[8,9,10], and clang-[9,11].

2021-06-08selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEVPetr Machata5-6/+14
In the commit referenced below, a check was added to devlink_lib that asserts the existence of a devlink device referenced by $DEVLINK_DEV. Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that does not exist at the time that devlink_lib is sourced. Thus these tests spuriously fail. Fix this by introducing an override. By setting DEVLINK_DEV to an empty string, the user declares their intention to handle DEVLINK_DEV management on their own. In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it to the correct value right afterwards.

To check how many routes are installed in hardware, the test runs "ip route" and greps for "offload", which includes routes with state "offload_failed". Till now, this wrong check was not found because after one failure in route insertion, the driver moved to "abort" mode, which means that user cannot try to add more routes. The previous patch removed the abort mechanism and now failed routes are counted as offloaded. Fix this by not considering routes with "offload_failed" flag as offloaded.

2021-06-08selftests, bpf: Make docs tests fail more reliablyJoe Stringer3-1/+4
Previously, if rst2man caught errors, then these would be ignored and the output file would be written anyway. This would allow developers to introduce regressions in the docs comments in the BPF headers. Additionally, even if you instruct rst2man to fail out, it will still write out to the destination target file, so if you ran the tests twice in a row it would always pass. Use a temporary file for the initial run to ensure that if rst2man fails out under "--strict" mode, subsequent runs will not automatically pass.

2021-06-08selftests: kvm: Add support for customized slot0 memory sizeZhenzhong Duan5-15/+45
Until commit 39fe2fc96694 ("selftests: kvm: make allocation of extra memory take effect", 2021-05-27), parameter extra_mem_pages was used only to calculate the page table size for all the memory chunks, because real memory allocation happened with calls of vm_userspace_mem_region_add() after vm_create_default(). Commit 39fe2fc96694 however changed the meaning of extra_mem_pages to the size of memory slot 0. This makes the memory allocation more flexible, but makes it harder to account for the number of pages needed for the page tables. For example, memslot_perf_test has a small amount of memory in slot 0 but a lot in other slots, and adding that memory twice (both in slot 0 and with later calls to vm_userspace_mem_region_add()) causes an error that was fixed in commit 000ac4295339 ("selftests: kvm: fix overlapping addresses in memslot_perf_test", 2021-05-29) Since both uses are sensible, add a new parameter slot0_mem_pages to vm_create_with_vcpus() and some comments to clarify the meaning of slot0_mem_pages and extra_mem_pages. With this change, memslot_perf_test can go back to passing the number of memory pages as extra_mem_pages.

2021-05-29selftests: kvm: fix overlapping addresses in memslot_perf_testPaolo Bonzini1-1/+1
vm_create allocates memory and maps it close to GPA. This memory is separate from what is allocated in subsequent calls to vm_userspace_mem_region_add, so it is incorrect to pass the test memory size to vm_create_default. Just pass a small fixed amount of memory which can be used later for page table, otherwise GPAs are already allocated at MEM_GPA and the test aborts. Signed-off-by: Paolo Bonzini <[email protected]>

2021-05-28bpf, docs: Add llvm_reloc.rst to explain llvm bpf relocationsYonghong Song1-0/+19
LLVM upstream commit https://reviews.llvm.org/D102712 made some changes to bpf relocations to make them llvm linker lld friendly. The scope of existing relocations R_BPF_64_{64,32} is narrowed and new relocations R_BPF_64_{ABS32,ABS64,NODYLD32} are introduced. Let us add some documentation about llvm bpf relocations so people can understand how to resolve them properly in their respective tools.
