Patch #2 fixes an issue with bridge netfilter and broadcast/multicast packets. There is a day 0 bug in br_netfilter when used with connection tracking. Conntrack assumes that an nf_conn structure that is not yet added to hash table ("unconfirmed"), is only visible by the current cpu that is processing the sk_buff. For bridge this isn't true, sk_buff can get cloned in between, and clones can be processed in parallel on different cpu. This patch disables NAT and conntrack helpers for multicast packets.

2024-02-28tools: ynl: wrap recv() + mnl_cb_run2() into a single helperJakub Kicinski
All callers to mnl_cb_run2() call mnl_socket_recvfrom() right before. Wrap the two in a helper, take typed arguments (struct ynl_parse_arg), instead of hoping that all callers remember that parser error handling requires yarg. In case of ynl_sock_read_family() we will no longer check for kernel returning no data, but that would be a kernel bug, not worth complicating the code to catch this. Calling mnl_cb_run2() on an empty buffer is legal and results in STOP (1).

Don't use mnl attr helpers, we're trying to remove the libmnl dependency. Create both signed and unsigned helpers, libmnl had unsigned helpers, so code generator no longer needs the mnl_type() hack.

2024-02-28tools: ynl: give up on libmnl for auto-intsJakub Kicinski
The temporary auto-int helpers are not really correct. We can't treat signed and unsigned ints the same when determining whether we need full 8B. I realized this before sending the patch to add support in libmnl. Unfortunately, that patch has not been merged, so time to fix our local helpers. Use the mnl* name for now, subsequent patches will address that.

2024-02-28tools: ynl: fix handling of multiple mcast groupsJakub Kicinski
We never increment the group number iterator, so all groups get recorded into index 0 of the mcast_groups[] array. As a result YNL can only handle using the last group. For example using the "netdev" sample on kernel with page pool commands results in: $ ./samples/netdev YNL: Multicast group 'mgmt' not found Most families have only one multicast group, so this hasn't been noticed. Plus perhaps developers usually test the last group which would have worked.

2024-02-27selftests: netdevsim: be less selective for FW for the devlink testJakub Kicinski
Commit 6151ff9c7521 ("selftests: netdevsim: use suitable existing dummy file for flash test") introduced a nice trick to the devlink flashing test. Instead of user having to create a file under /lib/firmware we just pick the first one that already exists. Sadly, in AWS Linux there are no files directly under /lib/firmware, only in subdirectories. Don't limit the search to -maxdepth 1. We can use the %P print format to get the correct path for files inside subdirectories: $ find /lib/firmware -type f -printf '%P\n' | head -1 intel-ucode/06-1a-05 The full path is /lib/firmware/intel-ucode/06-1a-05 This works in GNU find, busybox doesn't have printf at all, so we're not making it worse.

It is important to have a unique (sub)test name in TAP, because some CI environments drop tests with duplicated name. When adding a new subtest entry, an error message is printed in case of duplicated entries. If there were duplicated entries and if all features were expected to work, the script exits with an error at the end, after having printed all subtests in the TAP format.

2024-02-24Merge tag 'cxl-fixes-6.8-rc6' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull cxl fixes from Dan Williams: "A collection of significant fixes for the CXL subsystem. The largest change in this set, that bordered on "new development", is the fix for the fact that the location of the new qos_class attribute did not match the Documentation. The fix ends up deleting more code than it added, and it has a new unit test to backstop basic errors in this interface going forward. So the "red-diff" and unit test saved the "rip it out and try again" response. In contrast, the new notification path for firmware reported CXL errors (CXL CPER notifications) has a locking context bug that can not be fixed with a red-diff. Given where the release cycle stands, it is not comfortable to squeeze in that fix in these waning days. So, that receives the "back it out and try again later" treatment. There is a regression fix in the code that establishes memory NUMA nodes for platform CXL regions. That has an ack from x86 folks. There are a couple more fixups for Linux to understand (reassemble) CXL regions instantiated by platform firmware. The policy around platforms that do not match host-physical-address with system-physical-address (i.e. systems that have an address translation mechanism between the address range reported in the ACPI CEDT.CFMWS and endpoint decoders) has been softened to abort driver load rather than teardown the memory range (can cause system hangs). Lastly, there is a robustness / regression fix for cases where the driver would previously continue in the face of error, and a fixup for PCI error notification handling. Summary: - Fix NUMA initialization from ACPI CEDT.CFMWS - Fix region assembly failures due to async init order - Fix / simplify export of qos_class information - Fix cxl_acpi initialization vs single-window-init failures - Fix handling of repeated 'pci_channel_io_frozen' notifications - Workaround platforms that violate host-physical-address == system-physical address assumptions - Defer CXL CPER notification handling to v6.9" * tag 'cxl-fixes-6.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/acpi: Fix load failures due to single window creation failure acpi/ghes: Remove CXL CPER notifications cxl/pci: Fix disabling memory if DVSEC CXL Range does not match a CFMWS window cxl/test: Add support for qos_class checking cxl: Fix sysfs export of qos_class for memdev cxl: Remove unnecessary type cast in cxl_qos_class_verify() cxl: Change 'struct cxl_memdev_state' *_perf_list to single 'struct cxl_dpa_perf' cxl/region: Allow out of order assembly of autodiscovered regions cxl/region: Handle endpoint decoders in cxl_region_find_decoder() x86/numa: Fix the sort compare func used in numa_fill_memblks() x86/numa: Fix the address overlap check in numa_fill_memblks() cxl/pci: Skip to handle RAS errors if CXL.mem device is detached

2024-02-23tools: ynl: allow user to pass enum string instead of scalar valueJiri Pirko
During decoding of messages coming from kernel, attribute values are converted to enum names in case the attribute type is enum of bitfield32. However, when user constructs json message, he has to pass plain scalar values. See "state" "selector" and "value" attributes in following examples: $ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml --do pin-set --json '{"id": 0, "parent-device": {"parent-id": 0, "state": 1}}' $ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml --do port-set --json '{"bus-name": "pci", "dev-name": "0000:08:00.1", "port-index": 98304, "port-function": {"caps": {"selector": 1, "value": 1 }}}' Allow user to pass strings containing enum names, convert them to scalar values to be encoded into Netlink message: $ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml --do pin-set --json '{"id": 0, "parent-device": {"parent-id": 0, "state": "connected"}}' $ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml --do port-set --json '{"bus-name": "pci", "dev-name": "0000:08:00.1", "port-index": 98304, "port-function": {"caps": {"selector": ["roce-bit"], "value": ["roce-bit"] }}}' Signed-off-by: Jiri Pirko <jiri@nvidia.com> Reviewed-by: Donald Hunter <donald.hunter@gmail.com> Link: https://lore.kernel.org/r/20240222134351.224704-4-jiri@resnulli.us Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-02-22net: mctp: tests: Test that outgoing skbs have flow data populatedJeremy Kerr
When CONFIG_MCTP_FLOWS is enabled, outgoing skbs should have their SKB_EXT_MCTP extension set for drivers to consume. Add two tests for local-to-output routing that check for the flow extensions: one for the simple single-packet case, and one for fragmentation. We now make MCTP_TEST select MCTP_FLOWS, so we always get coverage of these flow tests. The tests are skippable if MCTP_FLOWS is (otherwise) disabled, but that would need manual config tweaking.

2024-02-22selftests: ioam: refactoring to align with the fixJustin Iurman
ioam6_parser uses a packet socket. After the fix to prevent writing to cloned skb's, the receiver does not see its IOAM data anymore, which makes input/forward ioam-selftests to fail. As a workaround, ioam6_parser now uses an IPv6 raw socket and leverages ancillary data to get hop-by-hop options. As a consequence, the hook is "after" the IOAM data insertion by the receiver and all tests are working again.

2024-02-21tools: ynl: make sure we always pass yarg to mnl_cb_runJakub Kicinski
There is one common error handler in ynl - ynl_cb_error(). It expects priv to be a pointer to struct ynl_parse_arg AKA yarg. To avoid potential crashes if we encounter a stray NLMSG_ERROR always pass yarg as priv (or a struct which has it as the first member). ynl_cb_null() has a similar problem directly - it expects yarg but priv passed by the caller is ys.
