[PATCH v3 00/20] RFCv3: Proof-of-concept conversion of some tests to Avocado framework
by David Gibson 31 May '23

31 May '23

As discussed on calls, I've been investigating Avocado as a possible replacement for our hand-rolled shell test framework. This is a third draft proof-of-concept conversion of a few of the tests to the Avocado framework. Specifically, the static checkers, the build tests and the pasta transfer tests are converted. This third version completely avoids the avocado/unittest built in setUp() and tearDown() functions. Instead it uses Python's with statement and context managers. This is more Pythonic, and avoids some really cryptic multiple inheritance confusion when we want to mix and match tests with different environment setups. Promising things: * I remain happy with the speed improvement (under half the time of the equivalent old tests) * The fact that it's no longer dependent on the host network is great * I'm cautiously optimistic about the helper library making it relatively easy to add a bunch more tests with further coverage Concerning things: * Using context managers instead of setUp/tearDown significantly mitigates it, but the OO/jUnit patterns still make things uglier. Changes since RFCv2: * Remove all setUp() and tearDown() implementations * Remove the weird 'subsetup' stuff we were using along with those Changes since RFCv1: * Sweeping rework of the test library * Started using tags to split between the "real" tests (run with "make avocado") and "meta" tests (run with "make avocado-meta"). The latter are tests for the test infrastructure and helpers themselves, rather than testing anything in passt or pasta David Gibson (20): avocado: Make a duplicate copy of testsuite for comparison purposes avocado: Don't double download assets for test/ and oldtest/ avocado: Move static checkers to avocado avocado/tasst: Helper functions for executing commands in different places avocado/tasst: Type checking helpers avocado: Convert build tests to avocado avocado/tasst: Add helpers for running background commands on sites avocado/tasst: Add helper to get network interface names for a site avocado/tasst: Add helpers to run commands with nstool avocado/tasst: Add ifup and network address helpers to Site avocado/tasst: Helper for creating veth devices between namespaces avocado/tasst: Add helper for getting MTU of a network interface avocado/tasst: Add helper to wait for IP address to appear avocado/tasst: Add helpers for getting a site's routes avocado/tasst: Helpers for test transferring data between sites avocado/tasst: IP address allocation helpers avocado/tasst: Helpers for testing NDP behaviour avocado/tasst: Helpers for testing DHCP & DHCPv6 behaviour avocado/tasst: Helpers to construct a simple network environment for tests avocado: Convert basic pasta tests Makefile | 19 + avocado/.gitignore | 1 + avocado/build.py | 81 +++ avocado/pasta.py | 195 ++++++ avocado/static_checkers/clang-tidy.sh | 3 + avocado/static_checkers/cppcheck.sh | 3 + avocado/tasst/__init__.py | 22 + avocado/tasst/address.py | 89 +++ avocado/tasst/dhcp.py | 152 +++++ avocado/tasst/dhcpv6.py | 135 +++++ avocado/tasst/meta/__init__.py | 16 + avocado/tasst/meta/static_ifup.py | 59 ++ avocado/tasst/meta/veth.py | 95 +++ avocado/tasst/ndp.py | 137 +++++ avocado/tasst/nstool.py | 199 +++++++ avocado/tasst/scenario/__init__.py | 11 + avocado/tasst/scenario/simple.py | 98 +++ avocado/tasst/site.py | 226 +++++++ avocado/tasst/transfer.py | 224 +++++++ avocado/tasst/typing.py | 23 + oldtest/.gitignore | 11 + oldtest/Makefile | 119 ++++ oldtest/README.md | 137 +++++ {test => oldtest}/build/all | 0 {test => oldtest}/build/clang_tidy | 0 {test => oldtest}/build/cppcheck | 0 oldtest/ci | 1 + oldtest/demo/passt | 245 ++++++++ oldtest/demo/pasta | 274 +++++++++ oldtest/demo/podman | 819 ++++++++++++++++++++++++++ oldtest/distro/debian | 252 ++++++++ oldtest/distro/fedora | 396 +++++++++++++ oldtest/distro/opensuse | 208 +++++++ oldtest/distro/ubuntu | 216 +++++++ oldtest/env/mate-terminal.profile | 42 ++ oldtest/find-arm64-firmware.sh | 13 + oldtest/lib/context | 130 ++++ oldtest/lib/layout | 259 ++++++++ oldtest/lib/layout_ugly | 113 ++++ oldtest/lib/perf_report | 272 +++++++++ oldtest/lib/setup | 385 ++++++++++++ oldtest/lib/setup_ugly | 58 ++ oldtest/lib/term | 750 +++++++++++++++++++++++ oldtest/lib/test | 398 +++++++++++++ oldtest/lib/util | 133 +++++ oldtest/lib/video | 152 +++++ oldtest/memory/passt | 187 ++++++ oldtest/nstool.c | 565 ++++++++++++++++++ oldtest/passt.mbuto | 83 +++ oldtest/passt.mem.mbuto | 44 ++ oldtest/passt/dhcp | 70 +++ oldtest/passt/ndp | 33 ++ oldtest/passt/shutdown | 19 + oldtest/passt/tcp | 76 +++ oldtest/passt/udp | 46 ++ oldtest/passt_in_ns/icmp | 32 + oldtest/passt_in_ns/shutdown | 19 + oldtest/passt_in_ns/tcp | 256 ++++++++ oldtest/passt_in_ns/udp | 138 +++++ {test => oldtest}/pasta/dhcp | 0 {test => oldtest}/pasta/ndp | 0 {test => oldtest}/pasta/tcp | 0 {test => oldtest}/pasta/udp | 0 oldtest/pasta_options/log_to_file | 93 +++ oldtest/perf/passt_tcp | 215 +++++++ oldtest/perf/passt_udp | 165 ++++++ oldtest/perf/pasta_tcp | 300 ++++++++++ oldtest/perf/pasta_udp | 219 +++++++ oldtest/prepare-distro-img.sh | 18 + oldtest/run | 238 ++++++++ oldtest/run_demo | 1 + oldtest/two_guests/basic | 80 +++ oldtest/valgrind.supp | 9 + test/lib/layout | 31 -

[PATCH v2 00/10] Optionally copy all routes and addresses for pasta, allow gateway-less routes
by Stefano Brivio 27 May '23

27 May '23

This series, along with pseudo-related fixes, enables: - optional copy of all routes from selected interface in outer namespace, to fix the issue reported by Callum at: https://github.com/containers/podman/issues/18539 - optional copy of all addresses, mostly for consistency. It doesn't, however, enable assignment of multiple addresses in the sense requested at: https://bugs.passt.top/show_bug.cgi?id=47 because the addresses still need to be present on the host, and the "outer" address isn't selected depending on the address used inside the container - operation without a gateway address. This is related to: https://bugs.passt.top/show_bug.cgi?id=49 but Wireguard endpoints established outside the container can't be used yet as outbound interface (without the workaround reported there) for a number of reasons I'm still investigating. In any case, the correct route is now configured in the container, even without a default gateway on the corresponding host route, so we're a bit closer to support that configuration out of the box. v2: - in 3/10, repeat the netlink request once for each RTM_NEWROUTE we're going to send as part of the request: routes might depend on each other, and this is a somewhat rudimentary, but seemingly robust approach to insert all the routes we can insert, without explicitly calculating dependencies - Cc: Andrea, reporter for the issue fixed in 4/10 Stefano Brivio (10): netlink: Fix comment about response buffer size for nl_req() pasta: Improve error handling on failure to join network namespace netlink: Add functionality to copy routes from outer namespace conf: --config-net option is for pasta mode only conf, pasta: With --config-net, copy all routes by default Revert "conf: Adjust netmask on mismatch between IPv4 address/netmask and gateway" conf: Don't exit if sourced default route has no gateway netlink: Add functionality to copy addresses from outer namespace conf, pasta: With --config-net, copy all addresses by default passt.h: Fix description of pasta_ifi in struct ctx conf.c | 81 +++++++++++++++++++------------- netlink.c | 135 +++++++++++++++++++++++++++++++++++++++++------------- netlink.h | 13 ++++-- passt.1 | 25 +++++++++- passt.h | 8 +++- pasta.c | 26 +++++++---- 6 files changed, 207 insertions(+), 81 deletions(-) -- 2.39.2

[PATCH v2 0/3] Fix pasta-in-pasta operation (and similar)
by Stefano Brivio 23 May '23

23 May '23

When pasta spawns a command (operation without pre-existing namespace), it calls clone(2) with CLONE_NEWPID to detach the PID namespace where this command runs, but it needs to mount /proc (in a separate mount namespace), otherwise its contents are not consistent with the new PID namespace. If /proc contents are not consistent, pasta will fail to run in a user and network namespace created by another pasta instance. An alternative would be to drop CLONE_NEWPID altogether: pasta itself not a container engine, and it's not meant to provide general isolation features other than for networking aspects. This would also make testing and debugging a bit easier, as the PIDs of processes descending from pasta would be the same outside the detached namespace. However, also for testing and debugging usage itself, we would lose two advantages: the inner environment looks more observable (from inside) with CLONE_NEWPID, and we don't need to explicitly clean up the environment as pasta terminates: see the ugliness of pasta_ns_cleanup() before commit 0515adceaa8f ("passt, pasta: Namespace-based sandboxing, defer seccomp policy application"). It wasn't very robust either. Now that this part works, note that writing to the uid_map procfs entry, with 0 as domain for the map, requires (since Linux 5.12) CAP_SETFCAP in the parent process. We need this mapping to keep the behaviour consistent with what happens when we run directly from the init namespace, and to set the ping_group_range sysctl. Keep CAP_SETFCAP if we're running with UID 0 from a non-init user namespace. With this series, pasta finally runs in itself. I checked basic connectivity inside a dozen of recursively nested instances. v2: Fix size of buffer and comparison in 1/3 for ns_is_init(), address comment from David Stefano Brivio (3): util, conf: Add and use ns_is_init() helper pasta: Detach mount namespace, (re)mount procfs before spawning command isolation: Initially Keep CAP_SETFCAP if running as UID 0 in non-init conf.c | 16 +--------------- isolation.c | 17 ++++++++++++++--- pasta.c | 7 ++++++- util.c | 25 +++++++++++++++++++++++++ util.h | 2 ++ 5 files changed, 48 insertions(+), 19 deletions(-) -- 2.39.2

[PATCH] tap: Don't update ip6.addr_seen to ::
by David Gibson 17 May '23

17 May '23

When we receive packets from the tap side, we update the addr_seen fields to reflect the last known address of the guest or ns. For ip4.addr_seen we, sensibly, only update if the address we've just seen isn't 0 (0.0.0.0). This case can occur during early DHCP transactions. We have no equivalent case for IPv6. We're less likely to hit this, because DHCPv6 uses link-local addresses, however we can see an source address of :: with certain multicast operations. This can bite us if we try to make an incoming connection very early after starting pasta with --config-net: we may have only seen some of those multicast packets, updated addr_seen to :: and not had any "real" packets to update it to a global address. I've seen this with some of the avocado test conversions. In any case, it can never make sense to update addr_seen to ::, so explicitly exclude that case.

[PATCH v2 00/21] RFCv2: Proof-of-concept conversion of some tests to Avocado framework
by David Gibson 16 May '23

16 May '23

As discussed on calls, I've been investigating Avocado as a possible replacement for our hand-rolled shell test framework. This is a second draft proof-of-concept conversion of a few of the tests to the Avocado framework. Specifically, the static checkers, the build tests and the pasta transfer tests are converted. In this second version, I've done a lot of rework (maybe too much) on the helper library. It's got a lot more capabilities and is more consistent. The new tests will get failures if you don't also apply the fix I send recently to prevent updating ip6.addr_seen to ::. Promising things: * I remain happy with the speed improvement (under half the time of the equivalent old tests) * The fact that it's no longer dependent on the host network is great * I'm cautiously optimistic about the helper library making it relatively easy to add a bunch more tests with further coverage Concerning things: * I'm coming to hate OO and jUnit patterns more and more, these can make it pretty non-obvious what each test relies on in terms of setup Changes since RFCv1: * Sweeping rework of the test library * Started using tags to split between the "real" tests (run with "make avocado") and "meta" tests (run with "make avocado-meta"). The latter are tests for the test infrastructure and helpers themselves, rather than testing anything in passt or pasta David Gibson (21): test/nstool: Provide useful error if given a path that's too long test/nstool: Fix fd leak in accept() loop avocado: Make a duplicate copy of testsuite for comparison purposes avocado: Don't double download assets for test/ and oldtest/ avocado: Move static checkers to avocado avocado/tasst: Helper functions for executing commands in different places avocado: Convert build tests to avocado avocado/tasst: Add helpers for running background commands on sites avocado/tasst: Add helper to get network interface names for a site avocado/tasst: Add helpers to run commands with nstool avocado/tasst: Add ifup and network address helpers to Site avocado/tasst: Helper for creating veth devices between namespaces avocado/tasst: Add helper for getting MTU of a network interface avocado/tasst: Add helper to wait for IP address to appear avocado/tasst: Add helpers for getting a site's routes avocado/tasst: Helpers for test transferring data between sites avocado/tasst: IP address allocation helpers avocado/tasst: Helpers for testing NDP behaviour avocado/tasst: Helpers for testing DHCP & DHCPv6 behaviour avocado/tasst: Helpers to construct a simple network environment for tests avocado: Convert basic pasta tests Makefile | 19 + avocado/.gitignore | 1 + avocado/build.py | 75 +++ avocado/pasta.py | 183 ++++++ avocado/static_checkers/clang-tidy.sh | 3 + avocado/static_checkers/cppcheck.sh | 3 + avocado/tasst/__init__.py | 32 + avocado/tasst/address.py | 89 +++ avocado/tasst/dhcp.py | 133 +++++ avocado/tasst/dhcpv6.py | 123 ++++ avocado/tasst/meta/__init__.py | 16 + avocado/tasst/meta/static_ifup.py | 60 ++ avocado/tasst/meta/veth.py | 95 +++ avocado/tasst/ndp.py | 129 ++++ avocado/tasst/nstool.py | 214 +++++++ avocado/tasst/scenario/__init__.py | 11 + avocado/tasst/scenario/simple.py | 96 +++ avocado/tasst/site.py | 207 +++++++ avocado/tasst/transfer.py | 228 +++++++ oldtest/.gitignore | 11 + oldtest/Makefile | 119 ++++ oldtest/README.md | 137 +++++ {test => oldtest}/build/all | 0 {test => oldtest}/build/clang_tidy | 0 {test => oldtest}/build/cppcheck | 0 oldtest/ci | 1 + oldtest/demo/passt | 245 ++++++++ oldtest/demo/pasta | 274 +++++++++ oldtest/demo/podman | 819 ++++++++++++++++++++++++++ oldtest/distro/debian | 252 ++++++++ oldtest/distro/fedora | 396 +++++++++++++ oldtest/distro/opensuse | 208 +++++++ oldtest/distro/ubuntu | 216 +++++++ oldtest/env/mate-terminal.profile | 42 ++ oldtest/find-arm64-firmware.sh | 13 + oldtest/lib/context | 130 ++++ oldtest/lib/layout | 259 ++++++++ oldtest/lib/layout_ugly | 113 ++++ oldtest/lib/perf_report | 272 +++++++++ oldtest/lib/setup | 385 ++++++++++++ oldtest/lib/setup_ugly | 58 ++ oldtest/lib/term | 750 +++++++++++++++++++++++ oldtest/lib/test | 398 +++++++++++++ oldtest/lib/util | 133 +++++ oldtest/lib/video | 152 +++++ oldtest/memory/passt | 187 ++++++ oldtest/nstool.c | 565 ++++++++++++++++++ oldtest/passt.mbuto | 83 +++ oldtest/passt.mem.mbuto | 44 ++ oldtest/passt/dhcp | 70 +++ oldtest/passt/ndp | 33 ++ oldtest/passt/shutdown | 19 + oldtest/passt/tcp | 76 +++ oldtest/passt/udp | 46 ++ oldtest/passt_in_ns/icmp | 32 + oldtest/passt_in_ns/shutdown | 19 + oldtest/passt_in_ns/tcp | 256 ++++++++ oldtest/passt_in_ns/udp | 138 +++++ {test => oldtest}/pasta/dhcp | 0 {test => oldtest}/pasta/ndp | 0 {test => oldtest}/pasta/tcp | 0 {test => oldtest}/pasta/udp | 0 oldtest/pasta_options/log_to_file | 93 +++ oldtest/perf/passt_tcp | 215 +++++++ oldtest/perf/passt_udp | 165 ++++++ oldtest/perf/pasta_tcp | 300 ++++++++++ oldtest/perf/pasta_udp | 219 +++++++ oldtest/prepare-distro-img.sh | 18 + oldtest/run | 238 ++++++++ oldtest/run_demo | 1 + oldtest/two_guests/basic | 80 +++ oldtest/valgrind.supp | 9 + test/lib/layout | 31 -
