2025-02-19selftests: drv-net: add a simple TSO testJakub Kicinski
Add a simple test for TSO. Send a few MB of data and check device stats to verify that the device was performing segmentation. Do the same thing over a few tunnel types. Injecting GSO packets directly would give us more ability to test corner cases, but perhaps starting simple is good enough? # ./ksft-net-drv/drivers/net/hw/tso.py # Detected qstat for LSO wire-packets KTAP version 1 1..14 ok 1 tso.ipv4 # SKIP Test requires IPv4 connectivity ok 2 tso.vxlan4_ipv4 # SKIP Test requires IPv4 connectivity ok 3 tso.vxlan6_ipv4 # SKIP Test requires IPv4 connectivity ok 4 tso.vxlan_csum4_ipv4 # SKIP Test requires IPv4 connectivity ok 5 tso.vxlan_csum6_ipv4 # SKIP Test requires IPv4 connectivity ok 6 tso.gre4_ipv4 # SKIP Test requires IPv4 connectivity ok 7 tso.gre6_ipv4 # SKIP Test requires IPv4 connectivity ok 8 tso.ipv6 ok 9 tso.vxlan4_ipv6 ok 10 tso.vxlan6_ipv6 ok 11 tso.vxlan_csum4_ipv6 ok 12 tso.vxlan_csum6_ipv6 # Testing with mangleid enabled ok 13 tso.gre4_ipv6 ok 14 tso.gre6_ipv6 # Totals: pass:7 fail:0 xfail:0 xpass:0 skip:7 error:0 Note that the test currently depends on the driver reporting the LSO count via qstat, which appears to be relatively rare (virtio, cisco/enic, sfc/efc; but virtio needs host support).

2025-02-19selftests: drv-net: store addresses in dict indexed by ipverJakub Kicinski
Looks like more and more tests want to iterate over IP version, run the same test over ipv4 and ipv6. The current naming of members in the env class makes it a bit awkward, we have separate members for ipv4 and ipv6 parameters. Store the parameters inside dicts, so that tests can easily index them with ip version.

This helper could be useful to more than just forwarding tests. Move it upstairs and port over to log_test_skip(). Split the function into two parts: the bit that actually checks and reports skip, which is in a new function check_command(). And a bit that exits the test script if the check fails.

2025-02-18selftest/bpf: Add vsock test for sockmap rejecting unconnectedMichal Luczaj
Verify that for a connectible AF_VSOCK socket, merely having a transport assigned is insufficient; socket must be connected for the sockmap to accept. This does not test datagram vsocks. Even though it hardly matters. VMCI is the only transport that features VSOCK_TRANSPORT_F_DGRAM, but it has an unimplemented vsock_transport::readskb() callback, making it unsupported by BPF/sockmap.

Commit 515745445e92 ("selftest/bpf: Add test for vsock removal from sockmap on close()") added test that checked if proto::close() callback was invoked on AF_VSOCK socket release. I.e. it verified that a close()d vsock does indeed get removed from the sockmap. It was done simply by creating a socket pair and attempting to replace a close()d one with its peer. Since, due to a recent change, sockmap does not allow updating index with a non-established connectible vsock, redo it with a freshly established one.

When testing if we should try to compact memory or drop caches before we run the THP or HugeTLB tests we use | as an or operator. This doesn't work since run_vmtests.sh is written in shell where this is used to pipe the output of the first argument into the second. Instead use the shell's -o operator.

2025-02-17getdelays: fix error format charactersWang Yaxin
getdelays had a compilation issue because the format string was not updated when the "delay min" was added. For example, after adding the "delay min" in printf, there were 7 strings but only 6 "%s" format specifiers. Similarly, after adding the 't->cpu_delay_total', there were 7 variables but only 6 format characters specifiers, causing compilation issues as follows. This commit fixes these issues to ensure that getdelays compiles correctly. root@xx:~/linux-next/tools/accounting$ make getdelays.c:199:9: warning: format `%llu' expects argument of type `long long unsigned int', but argument 8 has type `char *' [-Wformat=] 199 | printf("\n\nCPU %15s%15s%15s%15s%15s%15s\n" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ..... 216 | "delay total", "delay average", "delay max", "delay min", | ~~~~~~~~~~~ | | | char * getdelays.c:200:21: note: format string is defined here 200 | " %15llu%15llu%15llu%15llu%15.3fms%13.6fms\n" | ~~~~~^ | | | long long unsigned int | %15s getdelays.c:199:9: warning: format `%f' expects argument of type `double', but argument 12 has type `long long unsigned int' [-Wformat=] 199 | printf("\n\nCPU %15s%15s%15s%15s%15s%15s\n" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ..... 220 | (unsigned long long)t->cpu_delay_total, | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | | | long long unsigned int .....

2025-02-13sched_ext: Fix the incorrect bpf_list kfunc API in common.bpf.h.Chuyi Zhou
Now BPF only supports bpf_list_push_{front,back}_impl kfunc, not bpf_list_ push_{front,back}. This patch fix this issue. Without this patch, if we use bpf_list kfunc in scx, the BPF verifier would complain: libbpf: extern (func ksym) 'bpf_list_push_back': not found in kernel or module BTFs libbpf: failed to load object 'scx_foo' libbpf: failed to load BPF skeleton 'scx_foo': -EINVAL With this patch, the bpf list kfunc will work as expected.

2025-02-12objtool/rust: add one more `noreturn` Rust functionMiguel Ojeda
Starting with Rust 1.85.0 (currently in beta, to be released 2025-02-20), under some kernel configurations with `CONFIG_RUST_DEBUG_ASSERTIONS=y`, one may trigger a new `objtool` warning: rust/kernel.o: warning: objtool: _R...securityNtB2_11SecurityCtx8as_bytes() falls through to next function _R...core3ops4drop4Drop4drop() due to a call to the `noreturn` symbol: core::panicking::assert_failed::<usize, usize> Thus add it to the list so that `objtool` knows it is actually `noreturn`. Do so matching with `strstr` since it is a generic. See commit 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions") for more details. Cc: stable@vger.kernel.org # Needed in 6.12.y and 6.13.y only (Rust is pinned in older LTSs).

Add testcases to x86's Hyper-V CPUID test to verify that KVM advertises support for features that require an in-kernel local APIC appropriately, i.e. that KVM hides support from the vCPU-scoped ioctl if the VM doesn't have an in-kernel local APIC.

2025-02-12KVM: selftests: Manage CPUID array in Hyper-V CPUID test's core helperSean Christopherson
Allocate, get, and free the CPUID array in the Hyper-V CPUID test in the test's core helper, instead of copy+pasting code at each call site. In addition to deduplicating a small amount of code, restricting visibility of the array to a single invocation of the core test prevents "leaking" an array across test cases. Passing in @vcpu to the helper will also allow pivoting on VM-scoped information without needing to pass more booleans, e.g. to conditionally assert on features that require an in-kernel APIC. To avoid use-after-free bugs due to overzealous and careless developers, opportunstically add a comment to explain that the system-scoped helper caches the Hyper-V CPUID entries, i.e. that the caller is not responsible for freeing the memory.

2025-02-10selftests: drv-net: add helper for path resolutionJakub Kicinski
Refering to C binaries from Python code is going to be a common need. Add a helper to convert from path in relation to the test. Meaning, if the test is in the same directory as the binary, the call would be simply: cfg.rpath("binary"). The helper name "rpath" is not great. I can't think of a better name that would be accurate yet concise.
