[PATCH net-next 0/6] Add RTNL interface for SyncE

by Maciej Machnikowski

Synchronous Ethernet networks use a physical layer clock to syntonize the frequency across different network elements. Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to recover synchronization from the synchronization inputs - either traffic interfaces or external frequency sources. The EEC can synchronize its frequency (syntonize) to any of those sources. It is also able to select synchronization source through priority tables and synchronization status messaging. It also provides neccessary filtering and holdover capabilities This patch series introduces basic interface for reading the Ethernet Equipment Clock (EEC) state on a SyncE capable device. This state gives information about the source of the syntonization signal (ether my port, or any external one) and the state of EEC. This interface is required\ to implement Synchronization Status Messaging on upper layers. RFC history: v2: - removed whitespace changes - fix issues reported by test robot v3: - Changed naming from SyncE to EEC - Clarify cover letter and commit message for patch 1 v4: - Removed sync_source and pin_idx info - Changed one structure to attributes - Added EEC_SRC_PORT flag to indicate that the EEC is synchronized to the recovered clock of a port that returns the state v5: - add EEC source as an optiona attribute - implement support for recovered clocks - align states returned by EEC to ITU-T G.781 v6: - fix EEC clock state reporting - add documentation - fix descriptions in code comments Maciej Machnikowski (6): ice: add support detecting features based on netlist rtnetlink: Add new RTM_GETEECSTATE message to get SyncE status ice: add support for reading SyncE DPLL state rtnetlink: Add support for SyncE recovered clock configuration ice: add support for SyncE recovered clocks docs: net: Add description of SyncE interfaces Documentation/networking/synce.rst | 88 ++++++ drivers/net/ethernet/intel/ice/ice.h | 7 + .../net/ethernet/intel/ice/ice_adminq_cmd.h | 94 ++++++- drivers/net/ethernet/intel/ice/ice_common.c | 224 ++++++++++++++++ drivers/net/ethernet/intel/ice/ice_common.h | 20 +- drivers/net/ethernet/intel/ice/ice_devids.h | 3 + drivers/net/ethernet/intel/ice/ice_lib.c | 6 +- drivers/net/ethernet/intel/ice/ice_main.c | 138 ++++++++++ drivers/net/ethernet/intel/ice/ice_ptp.c | 34 +++ drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 49 ++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 22 ++ drivers/net/ethernet/intel/ice/ice_type.h | 1 + include/linux/netdevice.h | 33 +++ include/uapi/linux/if_link.h | 57 ++++ include/uapi/linux/rtnetlink.h | 10 + net/core/rtnetlink.c | 253 ++++++++++++++++++ security/selinux/nlmsgtab.c | 6 +- 17 files changed, 1041 insertions(+), 4 deletions(-) create mode 100644 Documentation/networking/synce.rst -- 2.26.3

[PATCH v2] tcp: Initial support for RFC5925 auth option

by Leonard Crestez

This is similar to TCP MD5 in functionality but it's sufficiently different that wire formats are incompatible. Compared to TCP-MD5 more algorithms are supported and multiple keys can be used on the same connection but there is still no negotiation mechanism. Expected use-case is protecting long-duration BGP/LDP connections between routers using pre-shared keys. The goal of this series is to allow routers using the linux TCP stack to interoperate with vendors such as Cisco and Juniper. Both algorithms described in RFC5926 are implemented but the code is not very easily extensible beyond that. In particular there are several code paths making stack allocations based on RFC5926 maximum, those would have to be increased. This version implements SNE and l3mdev awareness and adds more tests. Here are some known flaws and limitations: * Interaction with TCP-MD5 not tested in all corners * Interaction with FASTOPEN not tested and unlikely to work because sequence number assumptions for syn/ack. * Not clear if crypto_shash_setkey might sleep. If some implementation do that then maybe they could be excluded through alloc flags. * Traffic key is not cached (reducing performance) * User is responsible for ensuring keys do not overlap. * There is no useful way to list keys, making userspace debug difficult. * There is no prefixlen support equivalent to md5. This is used in some complex FRR configs. Test suite was added to tools/selftests/tcp_authopt. Tests are written in python using pytest and scapy and check the API in some detail and validate packet captures. Python code is already used in linux and in kselftests but virtualenvs not very much, this particular test suite uses `pip` to create a private virtualenv and hide dependencies. This actually forms the bulk of the series by raw line-count. Since there is a lot of code it was mostly split on "functional area" so most files are only affected by a single code. A lot of those tests are relevant to TCP-MD5 so perhaps it might help to split into a separate series? Some testing support is included in nettest and fcnal-test.sh, similar to the current level of tcp-md5 testing. SNE was tested by creating connections in a loop until a large SEQ is randomly selected and then making it rollover. The "connect in a loop" step ran into timewait overflow and connection failure on port reuse. After spending some time on this issue and my conclusion is that AO makes it impossible to kill remainders of old connections in a manner similar to unsigned or md5sig, this is because signatures are dependent on ISNs. This means that if a timewait socket is closed improperly then information required to RST the peer is lost. The fact that AO completely breaks all connection-less RSTs is acknowledged in the RFC and the workaround of "respect timewait" seems acceptable. Changes for frr (old): https://github.com/FRRouting/frr/pull/9442 That PR was made early for ABI feedback, it has many issues. Changes for yabgp (old): https://github.com/cdleonard/yabgp/commits/tcp_authopt This can be use for easy interoperability testing with cisco/juniper/etc. Changes since PATCH v1: * Implement Sequence Number Extension * Implement l3index for vrf: TCP_AUTHOPT_KEY_IFINDEX as equivalent of TCP_MD5SIG_FLAG_IFINDEX * Expand TCP-AO tests in fcnal-test.sh to near-parity with md5. * Show addr/port on failure similar to md5 * Remove tox dependency from test suite (create venv directly) * Switch default pytest output format to TAP (kselftest standard) * Fix _copy_from_sockptr_tolerant stack corruption on short sockopts. This was covered in test but error was invisible without STACKPROTECTOR=y * Fix sysctl_tcp_authopt check in tcp_get_authopt_val before memset. This was harmless because error code is checked in getsockopt anyway. * Fix dropping md5 packets on all sockets with AO enabled * Fix checking (key->recv_id & TCP_AUTHOPT_KEY_ADDR_BIND) instead of key->flags in tcp_authopt_key_match_exact * Fix PATCH 1/19 not compiling due to missing "int err" declaration * Add ratelimited message for AO and MD5 both present * Export all symbols required by CONFIG_IPV6=m (again) * Fix compilation with CONFIG_TCP_AUTHOPT=y CONFIG_TCP_MD5SIG=n * Fix checkpatch issues * Pass -rrequirements.txt to tox to avoid dependency variation. Link: https://lore.kernel.org/netdev/cover.1632240523.git.cdleonard@gmail.com/ Changes since RFCv3: * Implement TCP_AUTHOPT handling for timewait and reset replies. Write tests to execute these paths by injecting packets with scapy * Handle combining md5 and authopt: if both are configured use authopt. * Fix locking issues around send_key, introduced in on of the later patches. * Handle IPv4-mapped-IPv6 addresses: it used to be that an ipv4 SYN sent to an ipv6 socket with TCP-AO triggered WARN * Implement un-namespaced sysctl disabled this feature by default * Allocate new key before removing any old one in setsockopt (Dmitry) * Remove tcp_authopt_key_info.local_id because it's no longer used (Dmitry) * Propagate errors from TCP_AUTHOPT getsockopt (Dmitry) * Fix no-longer-correct TCP_AUTHOPT_KEY_DEL docs (Dmitry) * Simplify crypto allocation (Eric) * Use kzmalloc instead of __GFP_ZERO (Eric) * Add static_key_false tcp_authopt_needed (Eric) * Clear authopt_info copied from oldsk in __tcp_authopt_openreq (Eric) * Replace memcmp in ipv4 and ipv6 addr comparisons (Eric) * Export symbols for CONFIG_IPV6=m (kernel test robot) * Mark more functions static (kernel test robot) * Fix build with CONFIG_PROVE_RCU_LIST=y (kernel test robot) Link: https://lore.kernel.org/netdev/cover.1629840814.git.cdleonard@gmail.com/ Changes since RFCv2: * Removed local_id from ABI and match on send_id/recv_id/addr * Add all relevant out-of-tree tests to tools/testing/selftests * Return an error instead of ignoring unknown flags, hopefully this makes it easier to extend. * Check sk_family before __tcp_authopt_info_get_or_create in tcp_set_authopt_key * Use sock_owned_by_me instead of WARN_ON(!lockdep_sock_is_held(sk)) * Fix some intermediate build failures reported by kbuild robot * Improve documentation Link: https://lore.kernel.org/netdev/cover.1628544649.git.cdleonard@gmail.com/ Changes since RFC: * Split into per-topic commits for ease of review. The intermediate commits compile with a few "unused function" warnings and don't do anything useful by themselves. * Add ABI documention including kernel-doc on uapi * Fix lockdep warnings from crypto by creating pools with one shash for each cpu * Accept short options to setsockopt by padding with zeros; this approach allows increasing the size of the structs in the future. * Support for aes-128-cmac-96 * Support for binding addresses to keys in a way similar to old tcp_md5 * Add support for retrieving received keyid/rnextkeyid and controling the keyid/rnextkeyid being sent.

[PATCH] selftests/seccomp: Unconditionally define seccomp_metadata

by Luke Nowakowski-Krijger

There are conflicts between glibc system headers sys/ptrace.h and linux/ptrace.h that can likely cause seccomp_metadata not be defined depending on what version versions are installed, leading to compile errors. A solution to make this test more resitant to these system header differences is to rely on defintions inside of the file by unconditionally defining seccomp_metadata and removing the linux/ptrace.h include where a defintion of seccomp_metadata exists for certain headers.

[PATCH] selftests: net: reuseport_bpf_numa: skip nodes not available

by Kleber Sacilotto de Souza

In some platforms the numa node numbers are not necessarily consecutive, meaning that not all nodes from 0 to the value returned by numa_max_node() are available on the system. Using node numbers which are not available results on errors from libnuma such as: ---- IPv4 UDP ---- send node 0, receive socket 0 libnuma: Warning: Cannot read node cpumask from sysfs ./reuseport_bpf_numa: failed to pin to node: No such file or directory Fix it by checking if the node number bit is set on numa_nodes_ptr, which is defined on libnuma as "Set with all nodes the kernel has exposed to userspace".
