* fix f35 integration test network flakePaul Holzinger2022-05-25
| | | | | | | | | | | I am not 100% sure if this is actually causing the problem but I was able to reproduce locally and this change fixed it there. Without the `-n` option iptables tries to reverse lookup the ips to domain names. This is extremely slow for unknown reasons. Given the large amount of iptables entries due parallel test runs it will not succeed in the default 90 sec timeout. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* libpod: deduplicate ports in dbPaul Holzinger2021-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OCICNI port format has one big problem: It does not support ranges. So if a users forwards a range of 1k ports with podman run -p 1001-2000 we have to store each of the thousand ports individually as array element. This bloats the db and makes the JSON encoding and decoding much slower. In many places we already use a better port struct type which supports ranges, e.g. `pkg/specgen` or the new network interface. Because of this we have to do many runtime conversions between the two port formats. If everything uses the new format we can skip the runtime conversions. This commit adds logic to replace all occurrences of the old format with the new one. The database will automatically migrate the ports to new format when the container config is read for the first time after the update. The `ParsePortMapping` function is `pkg/specgen/generate` has been reworked to better work with the new format. The new logic is able to deduplicate the given ports. This is necessary the ensure we store them efficiently in the DB. The new code should also be more performant than the old one. To prove that the code is fast enough I added go benchmarks. Parsing 1 million ports took less than 0.5 seconds on my laptop. Benchmark normalize PortMappings in specgen: Please note that the 1 million ports are actually 20x 50k ranges because we cannot have bigger ranges than 65535 ports. ``` $ go test -bench=. -benchmem ./pkg/specgen/generate/ goos: linux goarch: amd64 pkg: github.com/containers/podman/v3/pkg/specgen/generate cpu: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz BenchmarkParsePortMappingNoPorts-12 480821532 2.230 ns/op 0 B/op 0 allocs/op BenchmarkParsePortMapping1-12 38972 30183 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMapping100-12 18752 60688 ns/op 141088 B/op 315 allocs/op BenchmarkParsePortMapping1k-12 3104 331719 ns/op 223840 B/op 3018 allocs/op BenchmarkParsePortMapping10k-12 376 3122930 ns/op 1223650 B/op 30027 allocs/op BenchmarkParsePortMapping1m-12 3 390869926 ns/op 124593840 B/op 4000624 allocs/op BenchmarkParsePortMappingReverse100-12 18940 63414 ns/op 141088 B/op 315 allocs/op BenchmarkParsePortMappingReverse1k-12 3015 362500 ns/op 223841 B/op 3018 allocs/op BenchmarkParsePortMappingReverse10k-12 343 3318135 ns/op 1223650 B/op 30027 allocs/op BenchmarkParsePortMappingReverse1m-12 3 403392469 ns/op 124593840 B/op 4000624 allocs/op BenchmarkParsePortMappingRange1-12 37635 28756 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange100-12 39604 28935 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange1k-12 38384 29921 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange10k-12 29479 40381 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange1m-12 927 1279369 ns/op 143022 B/op 164 allocs/op PASS ok github.com/containers/podman/v3/pkg/specgen/generate 25.492s ``` Benchmark convert old port format to new one: ``` go test -bench=. -benchmem ./libpod/ goos: linux goarch: amd64 pkg: github.com/containers/podman/v3/libpod cpu: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Benchmark_ocicniPortsToNetTypesPortsNoPorts-12 663526126 1.663 ns/op 0 B/op 0 allocs/op Benchmark_ocicniPortsToNetTypesPorts1-12 7858082 141.9 ns/op 72 B/op 2 allocs/op Benchmark_ocicniPortsToNetTypesPorts10-12 2065347 571.0 ns/op 536 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts100-12 138478 8641 ns/op 4216 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts1k-12 9414 120964 ns/op 41080 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts10k-12 781 1490526 ns/op 401528 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts1m-12 4 250579010 ns/op 40001656 B/op 4 allocs/op PASS ok github.com/containers/podman/v3/libpod 11.727s ``` Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Slirp4netns with ipv6 set net.ipv6.conf.default.accept_dad=0Paul Holzinger2021-10-26
| | | | | | | | | | | | | | Duplicate Address Detection slows the ipv6 setup down for 1-2 seconds. Since slirp4netns is run it is own namespace and not directly routed we can skip this to make the ipv6 address immediately available. We change the default to make sure the slirp tap interface gets the correct value assigned so DAD is disabled for it. Also make sure to change this value back to the original after slirp4netns is ready in case users rely on this sysctl. Fixes #11062 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* Eighty-six eighty-eightyEd Santiago2021-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (Sorry, couldn't resist). CI flakes have been coming down - thank you to everyone who has been making them a priority. This leaves a noisy subset that I've just been ignoring for months: Running: podman ... -p 8080:something ...cannot listen on the TCP port: listen tcp4 :8080: bind: address already in use Sometimes these are one-time errors resolved on 2nd try; sometimes they fail three times, forcing CI user to hit Rerun. In all cases they make noise in my flake logs, which costs me time. My assumption is that this has to do with ginkgo running random tests in parallel. Since many e2e tests simplemindedly use 8080, collisions are inevitable. Solution: simplemindedly replace 8080 with other (also arbitrarily picked) numbers. This is imperfect -- it requires human developers to pick a number NNNN and 'grep NNNN test/e2e/*' before adding new tests, which I am 100% confident ain't gonna happen -- but it's better than what we have now. Side note: I considered writing and using a RandomAvailablePort() helper, but that would still be racy. Plus, it would be a pain to interpolate strings into so many places. Finally, with this hand-tooled approach, if/when we _do_ get conflicts on port NNNN, it should be very easy to grep for NNNN, find the offending tests that reuse that port, and fix one of them.

* Only add 127.0.0.1 entry to /etc/hosts with --net=nonePaul Holzinger2021-09-16
| | | | | | | | | | | The check for net=none was wrong. It just assumed when we do not create the netns but have one set that we use the none mode. This however also applies to a container which joins the pod netns. To correctly check for the none mode use `config.NetMode.IsNone()`.

* Fix network aliases with network idPaul Holzinger2021-08-20
| | | | | | | | | | | | When a network id is used to create a container we translate it to use the name internally for the db. The network aliases are also stored with the network name as key so we have to also translate them for the db. Also removed some outdated skips from the e2e tests.

* Do not add an entry to /etc/hosts with `--net=host`Matthew Heon2021-08-04
| | | | | | | | | | | | | | | To match Docker's behavior, in the `--net=host` case, we need to use the host's `/etc/hosts` file, unmodified (without adding an entry for the container). We will still respect hosts from `--add-host` but will not make any automatic changes. Fortuntely, this is strictly a matter of removal and refactoring as we already base our `/etc/hosts` on the host's version - just need to remove the code that added entries when net=host was set.

* e2e tests: use Should(Exit()) and ExitWithError()Ed Santiago2021-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | e2e test failures are rife with messages like: Expected 1 to equal 0 These make me cry. They're anti-helpful, requiring the reader to dive into the source code to figure out what those numbers mean. Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I don't know if it spits out a better diagnostic (I have no way to run e2e tests on my laptop), but I have to fantasize that it will, and given the state of our flakes I assume that at least one test will fail and give me the opportunity to see what the error message looks like. THIS IS NOT REVIEWABLE CODE. There is no way for a human to review it. Don't bother. Maybe look at a few random ones for sanity. If you want to really review, here is a reproducer of what I did: cd test/e2e ! positive assertions. The second is the same as the first, ! with the addition of (unnecessary) parentheses because ! some invocations were written that way. The third is BeZero(). perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go ! Same as above, but handles three non-numeric exit codes ! in run_exit_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go ! negative assertions. Difference is the spelling of 'To(Not)', ! 'ToNot', and 'NotTo'. I assume those are all the same. perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go ! negative, old use of BeZero() perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go Run those on a clean copy of main branch (at the same branch point as my PR, of course), then diff against a checked-out copy of my PR. There should be no differences. Then all you have to review is that my replacements above are sane. UPDATE: nope, that's not enough, you also need to add gomega/gexec to the files that don't have it: perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}')) UPDATE 2: hand-edit run_volume_test.go UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places UPDATE 4: skip a test due to bug #10935 (race condition) Signed-off-by: Ed Santiago <santiago@redhat.com>
* Add the option of Rootless CNI networking by defaultMatthew Heon2021-05-26
| | | | | | | | | | | | | | | | | | | When the containers.conf field "NetNS" is set to "Bridge" and the "RootlessNetworking" field is set to "cni", Podman will now handle rootless in the same way it does root - all containers will be joined to a default CNI network, instead of exclusively using slirp4netns. If no CNI default network config is present for the user, one will be auto-generated (this also works for root, but it won't be nearly as common there since the package should already ship a config). I eventually hope to remove the "NetNS=Bridge" bit from containers.conf, but let's get something in for Brent to work with. Signed-off-by: Matthew Heon <mheon@redhat.com>
* podman image tree: restore previous behaviorValentin Rothberg2021-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial version of libimage changed the order of layers which has now been restored to remain backwards compatible. Further changes: * Fix a bug in the journald logging which requires to strip trailing new lines from the message. The system tests did not pass due to empty new lines. Triggered by changing the default logger to journald in containers/common. * Fix another bug in the journald logging which embedded the container ID inside the message rather than the specifid field. That surfaced in a preceeding whitespace of each log line which broke the system tests. * Alter the system tests to make sure that the k8s-file and the journald logging drivers are executed. * A number of e2e tests have been changed to force the k8s-file driver to make them pass when running inside a root container. * Increase the timeout in a kill test which seems to take longer now.

| | | | | | | | ed identified that the dnsname integration test does not use a unique name and therefore cannot be cleaned up. this was made worse by a improper defer statement to remove the network should the test fail. Signed-off-by: baude <bbaude@redhat.com>
* Fix dnsname when joining a different network namespace in a podPaul Holzinger2020-10-30
| | | | | | | | | | When creating a container in a pod the podname was always set as the dns entry. This is incorrect when the container is not part of the pods network namespace. This happend both rootful and rootless. To fix this check if we are part of the pods network namespace and if not use the container name as dns entry.

| * podman create doesn't support creating detached containersDaniel J Walsh2020-10-21
| | | | | | | | | | | | | | | | | | | | | | | | Detached containers and detach keys are only created with the podman run, i exec, and start commands. We do not store the detach key sequence or the detach flags in the database, nor does Docker. The current code was ignoreing these fields but documenting that they can be used. Fix podman create man page and --help output to no longer indicate that --detach and --detach-keys works. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* | Add hostname to /etc/hosts for --net=noneMatthew Heon2020-10-21
|/ | | | | | | | | This does not match Docker, which does not add hostname in this case, but it seems harmless enough. Fixes #8095 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Ensure that hostname is added to hosts with net=hostMatthew Heon2020-10-20
| | | | | | | | | | | | | | | | | | When a container uses --net=host the default hostname is set to the host's hostname. However, we were not creating any entries in `/etc/hosts` despite having a hostname, which is incorrect. This hostname, for Docker compat, will always be the hostname of the host system, not the container, and will be assigned to IP 127.0.1.1 (not the standard localhost address). Also, when `--hostname` and `--net=host` are both passed, still use the hostname from `--hostname`, not the host's hostname (we still use the host's hostname by default in this case if the `--hostname` flag is not passed).
