2023-03-27tools: ynl: default to treating enums as flags for mask generationJakub Kicinski2-5/+6
I was a bit too optimistic in commit bf51d27704c9 ("tools: ynl: fix get_mask utility routine"), not every mask we use is necessarily coming from an enum of type "flags". We also allow flipping an enum into flags on per-attribute basis. That's done by the 'enum-as-flags' property of an attribute. Restore this functionality, it's not currently used by any in-tree family. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

While testing the tool I noticed we miss the u16 type on payload create. On the code inspection it turned out we miss also u64 - add them. We also miss the decoding of u16 despite the fact `NlAttr` class supports it - add it.

2023-03-25tools: ynl: add the Python requirements.txt fileMichal Michalik1-0/+2
It is a good practice to state explicitly which are the required Python packages needed in a particular project to run it. The most commonly used way is to store them in the `requirements.txt` file*. *URL: https://pip.pypa.io/en/stable/reference/requirements-file-format/ Currently user needs to figure out himself that Python needs `PyYAML` and `jsonschema` (and theirs requirements) packages to use the tool. Add the `requirements.txt` for user convenience. How to use it: 1) (optional) Create and activate empty virtual environment: python3.X -m venv venv3X source ./venv3X/bin/activate 2) Install all the required packages: pip install -r requirements.txt or python -m pip install -r requirements.txt 3) Run the script! The `requirements.txt` file was tested for: * Python 3.6 * Python 3.8 * Python 3.10 Signed-off-by: Michal Michalik <michal.michalik@intel.com> Link: https://lore.kernel.org/r/20230323190802.32206-1-michal.michalik@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-03-21bootconfig: Fix testcase to increase max nodeMasami Hiramatsu (Google)1-4/+8
Since commit 6c40624930c5 ("bootconfig: Increase max nodes of bootconfig from 1024 to 8192 for DCC support") increased the max number of bootconfig node to 8192, the bootconfig testcase of the max number of nodes fails. To fix this issue, we can not simply increase the number in the test script because the test bootconfig file becomes too big (>32KB). To fix that, we can use a combination of three alphabets (26^3 = 17576). But with that, we can not express the 8193 (just one exceed from the limitation) because it also exceeds the max size of bootconfig. So, the first 26 nodes will just use one alphabet. With this fix, test-bootconfig.sh passes all tests.

Add new network selftests for the bonding device which exercise the ether type changing call paths. They also test for the recent syzbot bug[1] which causes a warning and results in wrong device flags (IFF_SLAVE missing). The test adds three bond devices and a nlmon device, enslaves one of the bond devices to the other and then uses the nlmon device for successful and unsuccesful enslaves both of which change the bond ether type. Thus we can test for both MASTER and SLAVE flags at the same time. If the flags are properly restored we get: TEST: Change ether type of an enslaved bond device with unsuccessful enslave [ OK ] TEST: Change ether type of an enslaved bond device with successful enslave [ OK ] [1] https://syzkaller.appspot.com/bug?id=391c7b1f6522182899efba27d891f1743e8eb3ef Signed-off-by: Nikolay Aleksandrov <razor@blackwall.org> Reviewed-by: Michal Kubiak <michal.kubiak@intel.com> Acked-by: Jonathan Toppins <jtoppins@redhat.com> Acked-by: Jay Vosburgh <jay.vosburgh@canonical.com> Signed-off-by: David S.

2023-03-17selftests: net: devlink_port_split.py: skip test if no suitable device availablePo-Hsu Lin1-5/+31
The `devlink -j port show` command output may not contain the "flavour" key, an example from Ubuntu 22.10 s390x LPAR(5.19.0-37-generic), with mlx4 driver and iproute2-5.15.0: {"port":{"pci/0001:00:00.0/1":{"type":"eth","netdev":"ens301"}, "pci/0001:00:00.0/2":{"type":"eth","netdev":"ens301d1"}, "pci/0002:00:00.0/1":{"type":"eth","netdev":"ens317"}, "pci/0002:00:00.0/2":{"type":"eth","netdev":"ens317d1"}}} This will cause a KeyError exception. Create a validate_devlink_output() to check for this "flavour" from devlink command output to avoid this KeyError exception. Also let it handle the check for `devlink -j dev show` output in main(). Apart from this, if the test was not started because the max lanes of the designated device is 0. The script will still return 0 and thus causing a false-negative test result. Use a found_max_lanes flag to determine if these tests were skipped due to this reason and return KSFT_SKIP to make it more clear.

This adds SOCK_STREAM and SOCK_SEQPACKET tests for invalid buffer case. It tries to read data to NULL buffer (data already presents in socket's queue), then uses valid buffer. For SOCK_STREAM second read must return data, because skbuff is not dropped, but for SOCK_SEQPACKET skbuff will be dropped by kernel, and 'recv()' will return EAGAIN.

2023-03-14pm-graph: sleepgraph: Avoid crashing on binary data in device namesTodd Brandt1-3/+2
A regression has occurred in the hid-sensor code where a device name string has not been initialized to 0, and ends up without a NULL char and is printed with %s. This includes random binary data in the device name, which makes its way into the ftrace output and ends up crashing sleepgraph because it expects the ftrace output to be ASCII only. For example: "HID-SENSOR-INT-020b?.39.auto" ends up in ftrace instead of "HID-SENSOR-INT-020b.39.auto". It causes this crash in sleepgraph: File "/usr/bin/sleepgraph", line 5579, in executeSuspend for line in fp: File "/usr/lib/python3.10/codecs.py", line 322, in decode (result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 1568: invalid start byte The issue is present in 6.3-rc1 and is described in full here: https://bugzilla.kernel.org/show_bug.cgi?id=217169 A separate fix has been submitted to have this issue repaired, but it has also exposed a larger bug in sleepgraph, since nothing should make sleepgraph crash. Sleepgraph needs to be able to handle binary data showing up in ftrace gracefully. Modify the ftrace processing code to treat it as potentially binary and to filter out binary data and leave just the ASCII.

The xen_shinfo_test started off with very few iterations, and the numbers we used in GUEST_SYNC() were precisely mapped to the RUNSTATE_xxx values anyway to start with. It has since grown quite a few more tests, and it's kind of awful to be handling them all as bare numbers. Especially when I want to add a new test in the middle. Define an enum for the test stages, and use it both in the guest code and the host switch statement. No functional change, if I can count to 24.

2023-03-14selftests: KVM: skip hugetlb tests if huge pages are not availablePaolo Bonzini1-9/+16
Right now, if KVM memory stress tests are run with hugetlb sources but hugetlb is not available (either in the kernel or because /proc/sys/vm/nr_hugepages is 0) the test will fail with a memory allocation error. This makes it impossible to add tests that default to hugetlb-backed memory, because on a machine with a default configuration they will fail. Therefore, check HugePages_Total as well and, if zero, direct the user to enable hugepages in procfs. Furthermore, return KSFT_SKIP whenever hugetlb is not available.
