[PATCH bpf-next v2 0/2] selftests: bpf: Migrate test_xdp_meta.sh to test_progs

by Bastien Curutchet

Hi all, This patch series continues the work to migrate the script tests into prog_tests. test_xdp_meta.sh uses the BPF programs defined in progs/test_xdp_meta.c to do a simple XDP/TC functional test that checks the metadata allocation performed by the bpf_xdp_adjust_meta() helper. This is already partly covered by two tests under prog_tests/: - xdp_context_test_run.c uses bpf_prog_test_run_opts() to verify the validity of the xdp_md context after a call to bpf_xdp_adjust_meta() - xdp_metadata.c ensures that these meta-data can be exchanged through an AF_XDP socket. However test_xdp_meta.sh also verifies that the meta-data initialized in the struct xdp_md is forwarded to the struct __sk_buff used by BPF programs at 'TC level'. To cover this, I add a test case in xdp_context_test_run.c that uses the same BPF programs from progs/test_xdp_meta.c. --- Changes in v2: - Add missing close_netns() - Use a unique 'close' label - Link to v1: https://lore.kernel.org/r/20241206-xdp_meta-v1-0-5c150618f6e9@bootlin.com --- Bastien Curutchet (2): selftests/bpf: test_xdp_meta: Rename BPF sections selftests/bpf: Migrate test_xdp_meta.sh into xdp_context_test_run.c tools/testing/selftests/bpf/Makefile | 1 - .../bpf/prog_tests/xdp_context_test_run.c | 87 ++++++++++++++++++++++ tools/testing/selftests/bpf/progs/test_xdp_meta.c | 4 +- tools/testing/selftests/bpf/test_xdp_meta.sh | 58 --------------- 4 files changed, 89 insertions(+), 61 deletions(-) --- base-commit: 0c30734c4f35c4784d3d3ca1bb89d9779045878c change-id: 20241203-xdp_meta-868307cd0e03 Best regards, -- Bastien Curutchet (eBPF Foundation) <bastien.curutchet(a)bootlin.com>

[PATCH v7 0/2] selftests/resctrl: SNC kernel support discovery

by Maciej Wieczor-Retman

Changes v7: - Include fallthrough in resctrlfs.c. - Check fp after opening empty cpus file. - Correct a comment and merge strings in snprintf(). Changes v6: - Rebase onto latest kselftest-next. - Looking at the two patches with a fresh eye decided to make a split along the lines of: - Patch 1/2 contains all of the code that relates to SNC mode detection and checking that detection's reliability. - Patch 2/2 contains checking kernel support for SNC and modifying the messages at the end of affected tests. Changes v5: - Tests are skipped if snc_unreliable was set. - Moved resctrlfs.c changes from patch 2/2 to 1/2. - Removed CAT changes since it's not impacted by SNC in the selftest. - Updated various comments. - Fixed a bunch of minor issues pointed out in the review. Changes v4: - Printing SNC warnings at the start of every test. - Printing SNC warnings at the end of every relevant test. - Remove global snc_mode variable, consolidate snc detection functions into one. - Correct minor mistakes. Changes v3: - Reworked patch 2. - Changed minor things in patch 1 like function name and made corrections to the patch message. Changes v2: - Removed patches 2 and 3 since now this part will be supported by the kernel. Sub-Numa Clustering (SNC) allows splitting CPU cores, caches and memory into multiple NUMA nodes. When enabled, NUMA-aware applications can achieve better performance on bigger server platforms. SNC support in the kernel was merged into x86/cache [1]. With SNC enabled and kernel support in place all the tests will function normally (aside from effective cache size). There might be a problem when SNC is enabled but the system is still using an older kernel version without SNC support. Currently the only message displayed in that situation is a guess that SNC might be enabled and is causing issues. That message also is displayed whenever the test fails on an Intel platform. Add a mechanism to discover kernel support for SNC which will add more meaning and certainty to the error message. Add runtime SNC mode detection and verify how reliable that information is. Series was tested on Ice Lake server platforms with SNC disabled, SNC-2 and SNC-4. The tests were also ran with and without kernel support for SNC. Series applies cleanly on kselftest/next.

[PATCH net-next v5 0/6] tls: implement key updates for TLS1.3

by Sabrina Dubroca

This adds support for receiving KeyUpdate messages (RFC 8446, 4.6.3 [1]). A sender transmits a KeyUpdate message and then changes its TX key. The receiver should react by updating its RX key before processing the next message. This patchset implements key updates by: 1. pausing decryption when a KeyUpdate message is received, to avoid attempting to use the old key to decrypt a record encrypted with the new key 2. returning -EKEYEXPIRED to syscalls that cannot receive the KeyUpdate message, until the rekey has been performed by userspace 3. passing the KeyUpdate message to userspace as a control message 4. allowing updates of the crypto_info via the TLS_TX/TLS_RX setsockopts This API has been tested with gnutls to make sure that it allows userspace libraries to implement key updates [2]. Thanks to Frantisek Krenzelok <fkrenzel(a)redhat.com> for providing the implementation in gnutls and testing the kernel patches. ======================================================================= Discussions around v2 of this patchset focused on how HW offload would interact with rekey. RX - The existing SW path will handle all records between the KeyUpdate message signaling the change of key and the new key becoming known to the kernel -- those will be queued encrypted, and decrypted in SW as they are read by userspace (once the key is provided, ie same as this patchset) - Call ->tls_dev_del + ->tls_dev_add immediately during setsockopt(TLS_RX) TX - After setsockopt(TLS_TX), switch to the existing SW path (not the current device_fallback) until we're able to re-enable HW offload - tls_device_sendmsg will call into tls_sw_sendmsg under lock_sock to avoid changing socket ops during the rekey while another thread might be waiting on the lock - We only re-enable HW offload (call ->tls_dev_add to install the new key in HW) once all records sent with the old key have been ACKed. At this point, all unacked records are SW-encrypted with the new key, and the old key is unused by both HW and retransmissions. - If there are no unacked records when userspace does setsockopt(TLS_TX), we can (try to) install the new key in HW immediately. - If yet another key has been provided via setsockopt(TLS_TX), we don't install intermediate keys, only the latest. - TCP notifies ktls of ACKs via the icsk_clean_acked callback. In case of a rekey, tls_icsk_clean_acked will record when all data sent with the most recent past key has been sent. The next call to sendmsg will install the new key in HW. - We close and push the current SW record before reenabling offload. If ->tls_dev_add fails to install the new key in HW, we stay in SW mode. We can add a counter to keep track of this. In addition: Because we can't change socket ops during a rekey, we'll also have to modify do_tls_setsockopt_conf to check ctx->tx_conf and only call either tls_set_device_offload or tls_set_sw_offload. RX already uses the same ops for both TLS_HW and TLS_SW, so we could switch between HW and SW mode on rekey. An alternative would be to have a common sendmsg which locks the socket and then calls the correct implementation. We'll need that anyway for the offload under rekey case, so that would only add a test to the SW path's ops (compared to the current code). That should allow us to simplify build_protos a bit, but might have a performance impact - we'll need to check it if we want to go that route. ======================================================================= Changes since v4: - add counter for received KeyUpdate messages - improve wording in the documentation - improve handling of bogus messages when looking for KeyUpdate's - some coding style clean ups Changes since v3: - rebase on top of net-next - rework tls_check_pending_rekey according to Jakub's feedback - add statistics for rekey: {RX,TX}REKEY{OK,ERROR} - some coding style clean ups Link: https://lore.kernel.org/netdev/cover.1731597571.git.sd@queasysnail.net/ [v4] Link: https://lore.kernel.org/netdev/cover.1691584074.git.sd@queasysnail.net/ [v3] Link: https://lore.kernel.org/netdev/cover.1676052788.git.sd@queasysnail.net/ [v2] Link: https://lore.kernel.org/netdev/cover.1673952268.git.sd@queasysnail.net/ [v1] Link: https://www.rfc-editor.org/rfc/rfc8446#section-4.6.3 [1] Link: https://gitlab.com/gnutls/gnutls/-/merge_requests/1625 [2] Sabrina Dubroca (6): tls: block decryption when a rekey is pending tls: implement rekey for TLS1.3 tls: add counters for rekey docs: tls: document TLS1.3 key updates selftests: tls: add key_generation argument to tls_crypto_info_init selftests: tls: add rekey tests Documentation/networking/tls.rst | 36 +++ include/net/tls.h | 3 + include/uapi/linux/snmp.h | 5 + net/tls/tls.h | 3 +- net/tls/tls_device.c | 2 +- net/tls/tls_main.c | 71 ++++- net/tls/tls_proc.c | 5 + net/tls/tls_sw.c | 140 ++++++--- tools/testing/selftests/net/tls.c | 478 +++++++++++++++++++++++++++++- 9 files changed, 682 insertions(+), 61 deletions(-) -- 2.47.1
