[PATCH v5 00/20] tcp: Initial support for RFC5925 auth option

by Leonard Crestez

This is similar to TCP-MD5 in functionality but it's sufficiently different that packet formats and interfaces 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. Support for arbitrary algorithms was requested in reply to previous posts but I believe there is no real use case for that. The current implementation is somewhat loose regarding configuration: * Overlaping MKTs can be configured despite what RFC5925 says * Current key can be deleted. RFC says this shouldn't be allowed but enforcing this belongs at an admin shell rather than in the kernel. * If multiple keys are valid for a destination the kernel picks one in an unpredictable manner (this can be overridden). These conditions could be tightened but it is not clear the kernel should spend effort to prevent misconfiguration from userspace. The current code is largely feature complete and well-tested but I am somewhat stuck on next steps for getting this into upstream. Any suggestions would be very welcome Here are some known flaws and limitations: * Unsigned packets are sent if AO is active but no keys are found. * Crypto API is used with buffers on the stack and inside struct sock, this might not work on all arches. I'm currently only testing x64 VMs * 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. * No way to limit keys on a per-port basis (used to be implicit with per-socket keys). * Not clear if crypto_ahash_setkey might sleep. If some implementation do that then maybe they could be excluded through alloc flags. * Traffic key is not cached (reducing performance) * No caching or hashing for key lookups so this will scale poorly with many keys There is relatively little code sharing with the TCP_MD5SIG feature and earlier versions shared even less. Unlike MD5 the AO feature is kept separate from the rest of the TCP code and reusing code would require many unrelated cleanup changes. I'm not convinced that "authopt" is particularly good naming convention, this name is a personal invention that does not appear anywhere else. The RFC calls this "tcp-ao". Perhaps TCP_AOSIG would be a better name and it would also make the close connection to TCP_MD5SIG more visible? Some testing support is included in nettest and fcnal-test.sh, similar to the current level of tcp-md5 testing. A more elaborate test suite using pytest and scapy is available out of tree: https://github.com/cdleonard/tcp-authopt-test That test suite is much larger that the kernel code and did not receive many comments in previous ports so I will attempt to push it separately (if at all). 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 used for easy interoperability testing with cisco/juniper/etc. Would need updates for global keys to avoid leaks Changes since PATCH v4: * Move the traffic_key context_bytes header to stack. If it's a constant string then ahash can fail unexpectedly. * Fix allowing unsigned traffic if all keys are marked norecv. * Fix crashing in __tcp_authopt_alg_init on failure. * Try to respect the rnextkeyid from SYN on SYNACK (new patch) * Fix incorrect check for TCP_AUTHOPT_KEY_DEL in __tcp_authopt_select_key * Improve docs on __tcp_authopt_select_key * Fix build with CONFIG_PROC_FS=n (kernel build robot) * Fix build with CONFIG_IPV6=n (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1640273966.git.cdleonard@gmail.com/ Changes since PATCH v3: * Made keys global (per-netns rather than per-sock). * Add /proc/net/tcp_authopt with a table of keys (not sockets). * Fix part of the shash/ahash conversion having slipped from patch 3 to patch 5 * Fix tcp_parse_sig_options assigning NULL incorrectly when both MD5 and AO are disabled (kernel build robot) * Fix sparse endianness warnings in prefix match (kernel build robot) * Fix several incorrect RCU annotations reported by sparse (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1638962992.git.cdleonard@gmail.com/ Changes since PATCH v2: * Protect tcp_authopt_alg_get/put_tfm with local_bh_disable instead of preempt_disable. This caused signature corruption when send path executing with BH enabled was interrupted by recv. * Fix accepted keyids not configured locally as "unexpected". If any key is configured that matches the peer then traffic MUST be signed. * Fix issues related to sne rollover during handshake itself. (Francesco) * Implement and test prefixlen (David) * Replace shash with ahash and reuse some of the MD5 code (Dmitry) * Parse md5+ao options only once in the same function (Dmitry) * Pass tcp_authopt_info into inbound check path, this avoids second rcu dereference for same packet. * Pass tcp_request_socket into inbound check path instead of just listen socket. This is required for SNE rollover during handshake and clearifies ISN handling. * Do not allow disabling via sysctl after enabling once, this is difficult to support well (David) * Verbose check for sysctl_tcp_authopt (Dmitry) * Use netif_index_is_l3_master (David) * Cleanup ipvx_addr_match (David) * Add a #define tcp_authopt_needed to wrap static key usage because it looks nicer. * Replace rcu_read_lock with rcu_dereference_protected in SNE updates (Eric) * Remove test suite Link: https://lore.kernel.org/netdev/cover.1635784253.git.cdleonard@gmail.com/ 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 v2 0/5] selftests/resctrl: Add resctrl_tests into kselftest set

by Shaopeng Tan

Hello, The aim of this series is to make resctrl_tests run by using kselftest framework. - I modify Makefile of resctrl_test and Makefile of selftest, to build/run resctrl_tests by using kselftest framework. - I set the limited time for resctrl_tests to 120 seconds, to ensure the resctrl_tests finish in limited time. - When resctrl file system is not supported or resctrl_tests is not run as root, return skip code of kselftest. - If it is not finish in limited time, terminate resctrl_tests same as executing ctrl+c. Difference from v1: - I change the order of patches according to Reinette's review. - "LDLIBS + = -lnuma" has no dependencies on this patch series, delete it from [PATCH v2 2/5]. - I separate the license info of Makefile into a new patch [PATCH v2 3/5]. - I separate "limited time" into a new patch [PATCH v2 4/5]. (There is no change in [PATCH v2 1/5] and [PATCH v2 5/5]) In addition, I think 120s is not a problem since some tests have longer timeout (e.g. net test is 300s), please let me know if this is wrong Thanks, Shaopeng Tan (5): selftests/resctrl: Kill the child process created by fork() when the SIGTERM signal comes selftests/resctrl: Make resctrl_tests run using kselftest framework selftests/resctrl: Add license to resctrl_test Makefile selftests/resctrl: Change default limited time to 120 seconds for resctrl_tests selftests/resctrl: Return KSFT_SKIP(4) if resctrlfile system is not supported or resctrl is not run as root tools/testing/selftests/Makefile | 1 + tools/testing/selftests/resctrl/Makefile | 20 +++++++------------ .../testing/selftests/resctrl/resctrl_tests.c | 4 ++-- tools/testing/selftests/resctrl/resctrl_val.c | 1 + tools/testing/selftests/resctrl/settings | 1 + 5 files changed, 12 insertions(+), 15 deletions(-) create mode 100644 tools/testing/selftests/resctrl/settings -- 2.27.0

[PATCH] kunit: tool: Import missing importlib.abc

by Michał Winiarski

Python 3.10.0 contains: 9e09849d20 ("bpo-41006: importlib.util no longer imports typing (GH-20938)") It causes importlib.util to no longer import importlib.abs, which leads to the following error when trying to use kunit with qemu: AttributeError: module 'importlib' has no attribute 'abc'. Did you mean: '_abc'? Add the missing import.
