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.

2025-02-18selftests: forwarding: lib: Move require_command to net, generalizePetr Machata
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. This allows users consistent checking behavior while giving an option to bail out from a single test without bailing out of the whole script.

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.

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 .....

2025-02-14rseq/selftests: Fix riscv rseq_offset_deref_addv inline asmStafford Horne
When working on OpenRISC support for restartable sequences I noticed and fixed these two issues with the riscv support bits. 1 The 'inc' argument to RSEQ_ASM_OP_R_DEREF_ADDV was being implicitly passed to the macro. Fix this by adding 'inc' to the list of macro arguments. 2 The inline asm input constraints for 'inc' and 'off' use "er", The riscv gcc port does not have an "e" constraint, this looks to be copied from the x86 port. Fix this by just using an "r" constraint. I have compile tested this only for riscv. However, the same fixes I use in the OpenRISC rseq selftests and everything passes with no issues.
