2023-04-14KVM: selftests: Print detailed info in PMU event filter assertsAaron Lewis1-6/+5
Provide the actual vs. expected count in the PMU event filter test's asserts instead of relying on pr_info() to provide the context, e.g. so that all information needed to triage a failure is readily available even if the environment in which the test is run captures only the assert itself.

2023-04-14KVM: selftests: Add helpers for PMC asserts in PMU event filter testAaron Lewis1-25/+27
Add helper macros to consolidate the asserts that a PMC is/isn't counting (branch) instructions retired. This will make it easier to add additional asserts related to counting instructions later on. No functional changes intended.

2023-04-14selftests/resctrl: Fix incorrect error return on test completeReinette Chatre1-1/+1
An error snuck in between two recent conflicting changes: Until recently ->setup() used negative values to indicate normal test termination. This was changed in commit fa10366cc6f4 ("selftests/resctrl: Allow ->setup() to return errors") that transitioned ->setup() to use negative values to indicate errors and a new END_OF_TESTS to indicate normal termination. commit 42e3b093eb7c ("selftests/resctrl: Fix set up schemata with 100% allocation on first run in MBM test") continued to use negative return to indicate normal test termination. Fix mbm_setup() to use the new END_OF_TESTS to indicate error-free test termination.

2023-04-14objtool: Include weak functions in global_noreturns checkJosh Poimboeuf1-4/+4
If a global function doesn't return, and its prototype has the __noreturn attribute, its weak counterpart must also not return so that it matches the prototype and meets call site expectations. To properly follow the compiled control flow at the call sites, change the global_noreturns check to include both global and weak functions. On the other hand, if a weak function isn't in global_noreturns, assume the prototype doesn't have __noreturn. Even if the weak function doesn't return, call sites treat it like a returnable function.

The main changes are: 1) Rework BPF verifier log behavior and implement it as a rotating log by default with the option to retain old-style fixed log behavior, from Andrii Nakryiko. 2) Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params, from Christian Ehrig. 3) Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton, from Alexei Starovoitov. 4) Optimize hashmap lookups when key size is multiple of 4, from Anton Protopopov. 5) Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps, from David Vernet. 6) Add support for stashing local BPF kptr into a map value via bpf_kptr_xchg(). This is useful e.g. for rbtree node creation for new cgroups, from Dave Marchevsky. 7) Fix BTF handling of is_int_ptr to skip modifiers to work around tracing issues where a program cannot be attached, from Feng Zhou. 8) Migrate a big portion of test_verifier unit tests over to test_progs -a verifier_* via inline asm to ease {read,debug}ability, from Eduard Zingerman. 9) Several updates to the instruction-set.rst documentation which is subject to future IETF standardization (https://lwn.net/Articles/926882/), from Dave Thaler. 10) Fix BPF verifier in the __reg_bound_offset's 64->32 tnum sub-register known bits information propagation, from Daniel Borkmann. 11) Add skb bitfield compaction work related to BPF with the overall goal to make more of the sk_buff bits optional, from Jakub Kicinski. 12) BPF selftest cleanups for build id extraction which stand on its own from the upcoming integration work of build id into struct file object, from Jiri Olsa. 13) Add fixes and optimizations for xsk descriptor validation and several selftest improvements for xsk sockets, from Kal Conley. 14) Add BPF links for struct_ops and enable switching implementations of BPF TCP cong-ctls under a given name by replacing backing struct_ops map, from Kui-Feng Lee. 15) Remove a misleading BPF verifier env->bypass_spec_v1 check on variable offset stack read as earlier Spectre checks cover this, from Luis Gerhorst. 16) Fix issues in copy_from_user_nofault() for BPF and other tracers to resemble copy_from_user_nmi() from safety PoV, from Florian Lehner and Alexei Starovoitov. 17) Add --json-summary option to test_progs in order for CI tooling to ease parsing of test results, from Manu Bretelle. 18) Batch of improvements and refactoring to prep for upcoming bpf_local_storage conversion to bpf_mem_cache_{alloc,free} allocator, from Martin KaFai Lau. 19) Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations, from Quentin Monnet. 20) Fix attaching fentry/fexit/fmod_ret/lsm to modules by extracting the module name from BTF of the target and searching kallsyms of the correct module, from Viktor Malik. 21) Improve BPF verifier handling of '<const> <cond> <non_const>' to better detect whether in particular jmp32 branches are taken, from Yonghong Song. 22) Allow BPF TCP cong-ctls to write app_limited of struct tcp_sock. A built-in cc or one from a kernel module is already able to write to app_limited, from Yixin Shen.

2023-04-14perf map: Delete two variable initialisations before null pointer checks in ↵Markus Elfring1-2/+1
sort__sym_from_cmp() Addresses of two data structure members were determined before corresponding null pointer checks in the implementation of the function “sort__sym_from_cmp”. Thus avoid the risk for undefined behaviour by removing extra initialisations for the local variables “from_l” and “from_r” (also because they were already reassigned with the same value behind this pointer check). This issue was detected by using the Coccinelle software.
