[PATCH 0/4] Tests for multiple architectures and distributions
by Stefano Brivio 28 Jan '22

28 Jan '22

This series adds tests for a mix of old and new Debian, Fedora, OpenSUSE and Ubuntu versions, on on aarch64, i386, ppc64, ppc64le, s390x, x86_64, plus prerequisites for these tests and some basic documentation about the testing framework itself. Stefano Brivio (4): test/lib/term: Allow for a wider variety of prompt characters in pane_wait() test/lib/test: Introduce 'def' directive for frequently used patterns test: Add distribution tests for several architectures and kernel versions test: Add basic documentation about test suite, and cool-retro-term profile README.md | 4 +- test/README.md | 104 ++++++++ test/distro/debian | 343 ++++++++++++++++++++++++++ test/distro/fedora | 563 +++++++++++++++++++++++++++++++++++++++++++ test/distro/opensuse | 182 ++++++++++++++ test/distro/ubuntu | 208 ++++++++++++++++ test/lib/term | 17 +- test/lib/test | 496 ++++++++++++++++++++------------------ test/run | 1 + 9 files changed, 1680 insertions(+), 238 deletions(-) create mode 100644 test/README.md create mode 100644 test/distro/debian create mode 100644 test/distro/fedora create mode 100644 test/distro/opensuse create mode 100644 test/distro/ubuntu -- 2.33.0

[PATCH 00/22] Fixes for non-x86_64, older kernels/glibc, and some more
by Stefano Brivio 28 Jan '22

28 Jan '22

This series carries fixes for issues that emerged from testing on architectures other than x86_64, older kernels and older versions of gcc and glibc (1/22 to 7/22, 9/22, 11/22 to 12/22), some logic bugs that appeared during further testing (8/22, 10/22, 20/22) and fixes for tests, scripts and documentation (remaining patches). passt and pasta should now work on multiple architectures, build starting from gcc 4.7 and glibc 2.19, and actually work on kernel versions >= 4.4 with glibc >= 2.25. Tests checking this are introduced in the next series. Note to package maintainers: ausyscall(8) is not used anymore to generate seccomp profiles. Stefano Brivio (22): tcp: Cover all usages of tcpi_snd_wnd with HAS_SND_WND tap, tcp: Fix two comparisons with different signedness reported by gcc 7 passt: Drop <linux/ipv6.h> include, carry own ipv6hdr and opt_hdr definitions Makefile, seccomp: Fix build for i386, ppc64, ppc64le util: Fall-back definitions for SECCOMP_RET_KILL_PROCESS, ETH_{MAX,MIN}_MTU seccomp: Introduce mechanism to allow per-arch syscalls tcp, netlink, HAS{BYTES_ACKED,MIN_RTT,GETRANDOM} and NETLINK_GET_STRICT_CHK conf, pasta: Explicitly pass CLONE_{NEWUSER,NEWNET} to setns() tcp, udp, util: Fixes for bitmap handling on big-endian, casts netlink: Fix swapped v4/v6-only flags in external interface detection pasta: Check for zero d_reclen returned by getdents64() syscall tcp: Don't round down MSS to >= 64KiB page size, but clamp it in any case seccomp: Add a number of alternate and per-arch syscalls demo/pasta: Don't wait for pasta to return to a prompt test/two_guests: Drop stray spaces after sleep directives perf/passt_udp: Lower failure throughput thresholds with big MTUs test/lib/setup: Don't rely on IFS to properly separate qemu arguments test/lib/video: Drop -preset ultrafast from ffmpeg arguments hooks/pre-push: Delete old versions, add -DGLIBC_NO_STATIC_NSS, disable legacy builds conf: Fix support for --stderr as short option (-e) README: Fix anchor for Performance section README: Fix link to IGMP/MLD proxy ticket Makefile | 29 ++++++++++++++++++-- README.md | 6 ++-- arp.c | 2 -- conf.c | 18 ++++++++---- dhcp.c | 2 -- dhcpv6.c | 2 -- hooks/pre-push | 18 +++++++----- icmp.c | 1 - ndp.c | 1 - netlink.c | 14 ++++++---- passt.c | 17 +++++++----- passt.h | 3 +- pasta.c | 13 +++++---- pcap.c | 2 -- qrap.c | 2 -- seccomp.sh | 63 +++++++++++++++++++++++++++++++++++------- tap.c | 5 ++-- tcp.c | 51 +++++++++++++++++++++++++++++----- test/demo/pasta | 2 +- test/lib/setup | 64 +++++++++++++++++++++---------------------- test/lib/video | 2 +- test/perf/passt_udp | 8 +++--- test/two_guests/basic | 8 +++--- udp.c | 6 ++-- util.c | 18 +++++++----- util.h | 40 +++++++++++++++++++++++++++ 26 files changed, 275 insertions(+), 122 deletions(-) -- 2.33.0
