* selftests: mptcp: userspace: fix v4-v6 test in v6.1Matthieu Baerts2023-02-221-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 4656d72c1efa ("selftests: mptcp: userspace: validate v4-v6 subflows mix") has been backported to v6.1.8 without any conflicts. But it looks like it was depending on a previous one: commit 1cc94ac1af4b ("selftests: mptcp: make evts global in userspace_pm") Without it, the test fails with: ./userspace_pm.sh: line 788: : No such file or directory # ADD_ADDR4 id:14 10.0.2.1 (ns1) => ns2, reuse port [FAIL] sed: can't read : No such file or directory This dependence refactors the way the monitoring files are being created: only once for all the different sub-tests instead of per sub-test. It is probably better to avoid backporting the refactoring. That is why the new sub-test has been adapted to work using the previous way that is still in place here in v6.1: the monitoring is started at the beginning of each sub-test and the created file is removed at the end.

* selftest: net: Improve IPV6_TCLASS/IPV6_HOPLIMIT tests apparmor compatibilityAndrei Gherzan2023-02-221-1/+1
| | | | | | | | | | | | | | | | | | | | | [ Upstream commit a6efc42a86c0c87cfe2f1c3d1f09a4c9b13ba890 ] "tcpdump" is used to capture traffic in these tests while using a random, temporary and not suffixed file for it. This can interfere with apparmor configuration where the tool is only allowed to read from files with 'known' extensions. The MINE type application/vnd.tcpdump.pcap was registered with IANA for pcap files and .pcap is the extension that is both most common but also aligned with standard apparmor configurations. See TCPDUMP(8) for more details. This improves compatibility with standard apparmor configurations by using ".pcap" as the file extension for the tests' temporary files.

* selftests: mptcp: stop tests earlierMatthieu Baerts2023-02-141-4/+10
| | | | | | | | | | | | | | | | | | | | | | commit 070d6dafacbaa9d1f2e4e3edc263853d194af15e upstream. These 'endpoint' tests from 'mptcp_join.sh' selftest start a transfer in the background and check the status during this transfer. Once the expected events have been recorded, there is no reason to wait for the data transfer to finish. It can be stopped earlier to reduce the execution time by more than half. For these tests, the exchanged data were not verified. Errors, if any, were ignored but that's fine, plenty of other tests are looking at that. It is then OK to mute stderr now that we are sure errors will be printed (and still ignored) because the transfer is stopped before the end.

* selftests: mptcp: allow more slack for slow test-casePaolo Abeni2023-02-141-2/+8
| | | | | | | | | | | | | | | | | | | | | | | commit a635a8c3df66ab68dc088c08a4e9e955e22c0e64 upstream. A test-case is frequently failing on some extremely slow VMs. The mptcp transfer completes before the script is able to do all the required PM manipulation. Address the issue in the simplest possible way, making the transfer even more slow. Additionally dump more info in case of failures, to help debugging similar problems in the future and init dump_stats var.

* cgroup/cpuset: Fix wrong check in update_parent_subparts_cpumask()Waiman Long2023-02-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | commit e5ae8803847b80fe9d744a3174abe2b7bfed222a upstream. It was found that the check to see if a partition could use up all the cpus from the parent cpuset in update_parent_subparts_cpumask() was incorrect. As a result, it is possible to leave parent with no effective cpu left even if there are tasks in the parent cpuset. This can lead to system panic as reported in [1]. Fix this probem by updating the check to fail the enabling the partition if parent's effective_cpus is a subset of the child's cpus_allowed. Also record the error code when an error happens in update_prstate() and add a test case where parent partition and child have the same cpu list and parent has task. Enabling partition in the child will fail in this case.

This can catch the system into a state where the datagrams are still in the system (for example in a qdisk, waiting for the network interface to return a completion notification, etc). This change adds a retry logic of computing the number of completions up to a configurable (via CLI) timeout (default: 2 seconds).

* selftests/net: l2_tos_ttl_inherit.sh: Run tests in their own netns.Guillaume Nault2023-01-181-69/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit c53cb00f7983a5474f2d36967f84908b85af9159 ] This selftest currently runs half in the current namespace and half in a netns of its own. Therefore, the test can fail if the current namespace is already configured with incompatible parameters (for example if it already has a veth0 interface). Adapt the script to put both ends of the veth pair in their own netns. Now veth0 is created in NS0 instead of the current namespace, while veth1 is set up in NS1 (instead of the 'testing' netns). The user visible netns names are randomised to minimise the risk of conflicts with already existing namespaces. The cleanup() function doesn't need to remove the virtual interface anymore: deleting NS0 and NS1 automatically removes the virtual interfaces they contained.

* mm: Always release pages to the buddy allocator in memblock_free_late().Aaron Thompson2023-01-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 115d9d77bb0f9152c60b6e8646369fa7f6167593 upstream. If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages() only releases pages to the buddy allocator if they are not in the deferred range. This is correct for free pages (as defined by for_each_free_mem_pfn_range_in_zone()) because free pages in the deferred range will be initialized and released as part of the deferred init process. memblock_free_pages() is called by memblock_free_late(), which is used to free reserved ranges after memblock_free_all() has run. All pages in reserved ranges have been initialized at that point, and accordingly, those pages are not touched by the deferred init process. This means that currently, if the pages that memblock_free_late() intends to release are in the deferred range, they will never be released to the buddy allocator. They will forever be reserved. In addition, memblock_free_pages() calls kmsan_memblock_free_pages(), which is also correct for free pages but is not correct for reserved pages. KMSAN metadata for reserved pages is initialized by kmsan_init_shadow(), which runs shortly before memblock_free_all(). For both of these reasons, memblock_free_pages() should only be called for free pages, and memblock_free_late() should call __free_pages_core() directly instead. One case where this issue can occur in the wild is EFI boot on x86_64. The x86 EFI code reserves all EFI boot services memory ranges via memblock_reserve() and frees them later via memblock_free_late() (efi_reserve_boot_services() and efi_free_boot_services(), respectively). If any of those ranges happens to fall within the deferred init range, the pages will not be released and that memory will be unavailable. For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI: v6.2-rc2: # grep -E 'Node|spanned|present|managed' /proc/zoneinfo Node 0, zone DMA spanned 4095 present 3999 managed 3840 Node 0, zone DMA32 spanned 246652 present 245868 managed 178867 v6.2-rc2 + patch: # grep -E 'Node|spanned|present|managed' /proc/zoneinfo Node 0, zone DMA spanned 4095 present 3999 managed 3840 Node 0, zone DMA32 spanned 246652 present 245868 managed 222816 # +43,949 pages Fixes: 3a80a7fa7989 ("mm: meminit: initialise a subset of struct pages if CONFIG_DEFERRED_STRUCT_PAGE_INIT is set") Signed-off-by: Aaron Thompson <dev@aaront.org> Link: https://lore.kernel.org/r/01010185892de53e-e379acfb-7044-4b24-b30a-e2657c1ba989-000000@us-west-2.amazonses.com Signed-off-by: Mike Rapoport (IBM) <rppt@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | | | | | | | | | commit ef784eebb56425eed6e9b16e7d47e5c00dcf9c38 upstream. After a full run of a make_min_config test, I noticed there were a lot of CONFIGs still enabled that really should not be. Looking at them, I noticed they were all defined as "default y". The issue is that the test simple removes the config and re-runs make oldconfig, which enables it again because it is set to default 'y'. Instead, explicitly disable the config with writing "# CONFIG_FOO is not set" to the file to keep it from being set again. With this change, one of my box's minconfigs went from 768 configs set, down to 521 configs set.
