Daniel Borkmann says: ==================== pull-request: bpf-next 2019-07-09 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Lots of libbpf improvements: i) addition of new APIs to attach BPF programs to tracing entities such as {k,u}probes or tracepoints, ii) improve specification of BTF-defined maps by eliminating the need for data initialization for some of the members, iii) addition of a high-level API for setting up and polling perf buffers for BPF event output helpers, all from Andrii. 2) Add "prog run" subcommand to bpftool in order to test-run programs through the kernel testing infrastructure of BPF, from Quentin. 3) Improve verifier for BPF sockaddr programs to support 8-byte stores for user_ip6 and msg_src_ip6 members given clang tends to generate such stores, from Stanislav. 4) Enable the new BPF JIT zero-extension optimization for further riscv64 ALU ops, from Luke. 5) Fix a bpftool json JIT dump crash on powerpc, from Jiri. 6) Fix an AF_XDP race in generic XDP's receive path, from Ilya. 7) Various smaller fixes from Ilya, Yue and Arnd. ==================== Signed-off-by: David S.

Pull tpm updates from Jarkko Sakkinen: "This contains two critical bug fixes and support for obtaining TPM events triggered by ExitBootServices(). For the latter I have to give a quite verbose explanation not least because I had to revisit all the details myself to remember what was going on in Matthew's patches. The preboot software stack maintains an event log that gets entries every time something gets hashed to any of the PCR registers. What gets hashed could be a component to be run or perhaps log of some actions taken just to give couple of coarse examples. In general, anything relevant for the boot process that the preboot software does gets hashed and a log entry with a specific event type [1]. The main application for this is remote attestation and the reason why it is useful is nicely put in the very first section of [1]: "Attestation is used to provide information about the platform’s state to a challenger. However, PCR contents are difficult to interpret; therefore, attestation is typically more useful when the PCR contents are accompanied by a measurement log. While not trusted on their own, the measurement log contains a richer set of information than do the PCR contents. The PCR contents are used to provide the validation of the measurement log." Because EFI_TCG2_PROTOCOL.GetEventLog() is not available after calling ExitBootServices(), Linux EFI stub copies the event log to a custom configuration table. Unfortunately, ExitBootServices() also generates events and obviously these events do not get copied to that table. Luckily firmware does this for us by providing a configuration table identified by EFI_TCG2_FINAL_EVENTS_TABLE_GUID. This essentially contains necessary changes to provide the full event log for the use the user space that is concatenated from these two partial event logs [2]" [1] https://trustedcomputinggroup.org/resource/pc-client-specific-platform-firmware-profile-specification/ [2] The final concatenation is done in drivers/char/tpm/eventlog/efi.c * tag 'tpmdd-next-20190625' of git://git.infradead.org/users/jjs/linux-tpmdd: tpm: Don't duplicate events from the final event log in the TCG2 log Abstract out support for locating an EFI config table tpm: Fix TPM 1.2 Shutdown sequence to prevent future TPM operations efi: Attempt to get the TCG2 event log in the boot stub tpm: Append the final event log to the TPM event log tpm: Reserve the TPM final events table tpm: Abstract crypto agile event size calculations tpm: Actually fail on TPM errors during "get random"

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking updates from Ingo Molnar: "The main changes in this cycle are: - rwsem scalability improvements, phase #2, by Waiman Long, which are rather impressive: "On a 2-socket 40-core 80-thread Skylake system with 40 reader and writer locking threads, the min/mean/max locking operations done in a 5-second testing window before the patchset were: 40 readers, Iterations Min/Mean/Max = 1,807/1,808/1,810 40 writers, Iterations Min/Mean/Max = 1,807/50,344/151,255 After the patchset, they became: 40 readers, Iterations Min/Mean/Max = 30,057/31,359/32,741 40 writers, Iterations Min/Mean/Max = 94,466/95,845/97,098" There's a lot of changes to the locking implementation that makes it similar to qrwlock, including owner handoff for more fair locking. Another microbenchmark shows how across the spectrum the improvements are: "With a locking microbenchmark running on 5.1 based kernel, the total locking rates (in kops/s) on a 2-socket Skylake system with equal numbers of readers and writers (mixed) before and after this patchset were: # of Threads Before Patch After Patch ------------ ------------ ----------- 2 2,618 4,193 4 1,202 3,726 8 802 3,622 16 729 3,359 32 319 2,826 64 102 2,744" The changes are extensive and the patch-set has been through several iterations addressing various locking workloads. There might be more regressions, but unless they are pathological I believe we want to use this new implementation as the baseline going forward. - jump-label optimizations by Daniel Bristot de Oliveira: the primary motivation was to remove IPI disturbance of isolated RT-workload CPUs, which resulted in the implementation of batched jump-label updates. Beyond the improvement of the real-time characteristics kernel, in one test this patchset improved static key update overhead from 57 msecs to just 1.4 msecs - which is a nice speedup as well. - atomic64_t cross-arch type cleanups by Mark Rutland: over the last ~10 years of atomic64_t existence the various types used by the APIs only had to be self-consistent within each architecture - which means they became wildly inconsistent across architectures. Mark puts and end to this by reworking all the atomic64 implementations to use 's64' as the base type for atomic64_t, and to ensure that this type is consistently used for parameters and return values in the API, avoiding further problems in this area. - A large set of small improvements to lockdep by Yuyang Du: type cleanups, output cleanups, function return type and othr cleanups all around the place. - A set of percpu ops cleanups and fixes by Peter Zijlstra. - Misc other changes - please see the Git log for more details" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (82 commits) locking/lockdep: increase size of counters for lockdep statistics locking/atomics: Use sed(1) instead of non-standard head(1) option locking/lockdep: Move mark_lock() inside CONFIG_TRACE_IRQFLAGS && CONFIG_PROVE_LOCKING x86/jump_label: Make tp_vec_nr static x86/percpu: Optimize raw_cpu_xchg() x86/percpu, sched/fair: Avoid local_clock() x86/percpu, x86/irq: Relax {set,get}_irq_regs() x86/percpu: Relax smp_processor_id() x86/percpu: Differentiate this_cpu_{}() and __this_cpu_{}() locking/rwsem: Guard against making count negative locking/rwsem: Adaptive disabling of reader optimistic spinning locking/rwsem: Enable time-based spinning on reader-owned rwsem locking/rwsem: Make rwsem->owner an atomic_long_t locking/rwsem: Enable readers spinning on writer locking/rwsem: Clarify usage of owner's nonspinaable bit locking/rwsem: Wake up almost all readers in wait queue locking/rwsem: More optimal RT task handling of null owner locking/rwsem: Always release wait_lock before waking up tasks locking/rwsem: Implement lock handoff to prevent lock starvation locking/rwsem: Make rwsem_spin_on_owner() return owner state ...

This is overridden on s390, which yields the current cpu to the neighbouring cpu after a couple of retries, instead of blindly giving up the cpu to the hipervisor. This significantly improves stop_machine performance on s390 in overcommitted scenarios.

2019-07-07timer: Document TIMER_PINNEDPeter Xu
The flag hints the user that the pinned timers will always be run on a static CPU (because that should be what "pinned" means...) but that's not the truth, at least with the current implementation. For example, currently if a pinned timer is set up but later mod_timer() upon the pinned timer is invoked, mod_timer() will still try to queue the timer on the current processor and migrate the timer if necessary. Document it a bit with the definition of TIMER_PINNED so that all future users will use it correctly.

Always contain all acceleration functions declarations in 'accel' files, independent to the flags setting. For this, introduce new flags CONFIG_FPGA_{IPSEC/TLS} and use stubs where needed. This obsoletes the need for stubs in 'fpga' files. Remove them. Also use the new flags in Makefile, to decide whether to compile TLS-specific or IPSEC-specific objects, or not.

Let me know if you run into any issues. Anyway, the main changes are: 1) Long-awaited AF_XDP support for mlx5e driver, from Maxim. 2) Addition of two new per-cgroup BPF hooks for getsockopt and setsockopt along with a new sockopt program type which allows more fine-grained pass/reject settings for containers. Also add a sock_ops callback that can be selectively enabled on a per-socket basis and is executed for every RTT to help tracking TCP statistics, both features from Stanislav. 3) Follow-up fix from loops in precision tracking which was not propagating precision marks and as a result verifier assumed that some branches were not taken and therefore wrongly removed as dead code, from Alexei. 4) Fix BPF cgroup release synchronization race which could lead to a double-free if a leaf's cgroup_bpf object is released and a new BPF program is attached to the one of ancestor cgroups in parallel, from Roman. 5) Support for bulking XDP_TX on veth devices which improves performance in some cases by around 9%, from Toshiaki. 6) Allow for lookups into BPF devmap and improve feedback when calling into bpf_redirect_map() as lookup is now performed right away in the helper itself, from Toke. 7) Add support for fq's Earliest Departure Time to the Host Bandwidth Manager (HBM) sample BPF program, from Lawrence. 8) Various cleanups and minor fixes all over the place from many others. ==================== Signed-off-by: David S.

2019-07-03nfsd: escape high characters in binary dataJ. Bruce Fields
I'm exposing some information about NFS clients in pseudofiles. I expect to eventually have simple tools to help read those pseudofiles. But it's also helpful if the raw files are human-readable to the extent possible. It aids debugging and makes them usable on systems that don't have the latest nfs-utils. A minor challenge there is opaque client-generated protocol objects like state owners and client identifiers. Some clients generate those to include handy information in plain ascii. But they may also include arbitrary byte sequences. I think the simplest approach is to limit to isprint(c) && isascii(c) and escape everything else. That means you can just cat the file and get something that looks OK. Also, I'm trying to keep these files legal YAML, which requires them to UTF-8, and this is a simple way to guarantee that.

Do as the NLM client: allocate and track a struct nlm_lockowner for use as the fl_owner for locks created by the NLM sever. This allows us to keep the svid within this structure for matching locks, and will allow us to track the pid of lockd in a future patch. It should also allow easier reference of the nlm_host in conflicting locks, and simplify lock hashing and comparison.

2019-07-03net/mlx5: Introduce and use mlx5_eswitch_get_total_vports()Parav Pandit
Instead MLX5_TOTAL_VPORTS, use mlx5_eswitch_get_total_vports(). mlx5_eswitch_get_total_vports() in subsequent patch accounts for SF vports as well. Expanding MLX5_TOTAL_VPORTS macro would require exposing SF internals to more generic vport.h header file. Such exposure is not desired. Hence a mlx5_eswitch_get_total_vports() is introduced. Given that mlx5_eswitch_get_total_vports() API wants to work on const mlx5_core_dev*, change its helper functions also to accept const *dev.
