selftests: bonding: cause oops in bond_rr_gen_slave_id

2022-09-22T13:39:40Z

This bonding selftest used to cause a kernel oops on aarch64 and should be architectures agnostic. Signed-off-by: Jonathan Toppins Acked-by: Jay Vosburgh Signed-off-by: Jakub Kicinski

net: Add tests for bonding and team address list management

2022-09-16T13:34:01Z

Test that the bonding and team drivers clean up an underlying device's address lists (dev->uc, dev->mc) when the aggregated device is deleted. Test addition and removal of the LACPDU multicast address on underlying devices by the bonding driver. v2: * add lag_lib.sh to TEST_FILES v3: * extend bond_listen_lacpdu_multicast test to init_state up and down cases * remove some superfluous shell syntax and 'set dev ... up' commands Signed-off-by: Benjamin Poirier Signed-off-by: David S.

selftests: include bonding tests into the kselftest infra

2022-08-23T01:30:16Z

This creates a test collection in drivers/net/bonding for bonding specific kernel selftests. The first test is a reproducer that provisions a bond and given the specific order in how the ip-link(8) commands are issued the bond never transmits an LACPDU frame on any of its slaves.

Pull networking changes from Paolo Abeni: "Core: - Refactor the forward memory allocation to better cope with memory pressure with many open sockets, moving from a per socket cache to a per-CPU one - Replace rwlocks with RCU for better fairness in ping, raw sockets and IP multicast router. - Network-side support for IO uring zero-copy send. - A few skb drop reason improvements, including codegen the source file with string mapping instead of using macro magic. - Rename reference tracking helpers to a more consistent netdev_* schema. - Adapt u64_stats_t type to address load/store tearing issues. - Refine debug helper usage to reduce the log noise caused by bots. BPF: - Improve socket map performance, avoiding skb cloning on read operation. - Add support for 64 bits enum, to match types exposed by kernel. - Introduce support for sleepable uprobes program. - Introduce support for enum textual representation in libbpf. - New helpers to implement synproxy with eBPF/XDP. - Improve loop performances, inlining indirect calls when possible. - Removed all the deprecated libbpf APIs. - Implement new eBPF-based LSM flavor. - Add type match support, which allow accurate queries to the eBPF used types. - A few TCP congetsion control framework usability improvements. - Add new infrastructure to manipulate CT entries via eBPF programs. - Allow for livepatch (KLP) and BPF trampolines to attach to the same kernel function. Protocols: - Introduce per network namespace lookup tables for unix sockets, increasing scalability and reducing contention. - Preparation work for Wi-Fi 7 Multi-Link Operation (MLO) support. - Add support to forciby close TIME_WAIT TCP sockets via user-space tools. - Significant performance improvement for the TLS 1.3 receive path, both for zero-copy and not-zero-copy. - Support for changing the initial MTPCP subflow priority/backup status - Introduce virtually contingus buffers for sockets over RDMA, to cope better with memory pressure. - Extend CAN ethtool support with timestamping capabilities - Refactor CAN build infrastructure to allow building only the needed features. Driver API: - Remove devlink mutex to allow parallel commands on multiple links. - Add support for pause stats in distributed switch. - Implement devlink helpers to query and flash line cards. - New helper for phy mode to register conversion.

selftests: netdevsim: Add test cases for route deletion failure

2022-07-29T11:21:02Z

Add IPv4 and IPv6 test cases that ensure that we are not leaking a reference on the nexthop device when we are unable to delete its associated route. Without the fix in a previous patch ("netdevsim: fib: Fix reference count leak on route deletion failure") both test cases get stuck, waiting for the reference to be released from the dummy device [1][2].

selftests: net: dsa: Add a Makefile which installs the selftests

Add a Makefile which takes care of installing the selftests in tools/testing/selftests/drivers/net/dsa. This can be used to install all DSA specific selftests and forwarding.config using the same approach as for the selftests in tools/testing/selftests/net/forwarding.

selftests: stop using KSFT_KHDR_INSTALL

2022-07-11T23:23:30Z

Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers from the kselftest Makefile is causing some issues. Instead, rely on the headers to be installed directly by the top-level Makefile "headers_install" make target prior to building kselftest.
