The CLONE_NEWTIME allows the creation of time namespaces. The flag reuses a bit from the CSIGNAL bits that are used in the legacy clone() system call to set the signal that gets sent to the parent after the child exits. The clone3() system call doesn't rely on CSIGNAL anymore as it uses a dedicated .exit_signal field in struct clone_args. So we blocked all CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced and reused a CSIGNAL bit we forgot to adapt clone3_args_valid() causing CLONE_NEWTIME with clone3() to be rejected.

libbpf: Revert poisoning of strlcpy
This reverts commit 6d0c4b11e743("libbpf: Poison strlcpy()").
It added the pragma poison directive to libbpf_internal.h to protect
against accidental usage of strlcpy but ended up breaking the build for
toolchains based on libcs which provide the strlcpy() declaration from
string.h (e.g. uClibc-ng). The include order which causes the issue is:
string.h,
from Iibbpf_common.h:12,
from libbpf.h:20,
from libbpf_internal.h:26,

tools: ynl: fix enum-as-flags in the generic CLI
Lorenzo points out that the generic CLI is broken for the netdev
family. When I added the support for documentation of enums
(and sparse enums) the client script was not updated.
It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).

ynl: re-license uniformly under GPL-2.0 OR BSD-3-Clause
I was intending to make all the Netlink Spec code BSD-3-Clause to ease the adoption but it appears that: - I fumbled the uAPI and used "GPL WITH uAPI note" there - it gives people pause as they expect GPL in the kernel As suggested by Chuck re-license under dual. This gives us benefit of full BSD freedom while fulfilling the broad "kernel is under GPL" expectations.

bpf, test_run: fix &xdp_frame misplacement for LIVE_FRAMES
&xdp_buff and &xdp_frame are bound in a way that
xdp_buff->data_hard_start == xdp_frame
It's always the case and e.g. xdp_convert_buff_to_frame() relies on
this.
IOW, the following:
for (u32 i = 0; i < 0xdead; i++) {
xdpf = xdp_convert_buff_to_frame(&xdp);
xdp_convert_frame_to_buff(xdpf, &xdp);
}
shouldn't ever modify @xdpf's contents or the pointer itself.
However, "live packet" code wrongly treats &xdp_frame as part of its
context placed *before* the data_hard_start. With such flow,
data_hard_start is sizeof(*xdpf) off to the right and no longer points
to the XDP frame.
Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several
places and praying that there are no more miscalcs left somewhere in the
code, unionize ::frm with ::data in a flex array, so that both starts
pointing to the actual data_hard_start and the XDP frame actually starts
being a part of it, i.e. a part of the headroom, not the context.
A nice side effect is that the maximum frame size for this mode gets
increased by 40 bytes, as xdp_buff::frame_sz includes everything from
data_hard_start (-> includes xdpf already) to the end of XDP/skb shared
info.
Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it
hardcoded for 64 bit && 4k pages, it can be made more flexible later on.
Minor: align `&head->data` with how `head->frm` is assigned for
consistency.
Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for
clarity.
(was found while testing XDP traffic generator on ice, which calls
xdp_convert_frame_to_buff() for each XDP frame)

tools: ynl: use 1 as the default for first entry in attrs/ops
Pretty much all families use value: 1 or reserve as unspec the first entry in attribute set and the first operation. Make this the default. Update documentation (the doc for values of operations just refers back to doc for attrs so updating only attrs). Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

tools: ynl: fully inherit attrs in subsets
To avoid having to repeat the entire definition of an attribute
(including the value) use the Attr object from the original set.
In fact this is already the documented expectation.

perf stat: Fix counting when initial delay configured
When creating counters with initial delay configured, the enable_on_exec
field is not set. So we need to enable the counters later. The problem
is, when a workload is specified the target__none() is true. So we also
need to check stat_config.initial_delay.
In this change, we add a new field 'initial_delay' for struct target
which could be shared by other subcommands. And define
target__enable_on_exec() which returns whether enable_on_exec should be
set on normal cases.
Before this fix the event is not counted:
$ ./perf stat -e instructions -D 100 sleep 2
Events disabled
Events enabled
Performance counter stats for 'sleep 2':
<not counted> instructions
1.901661124 seconds time elapsed
0.001602000 seconds user
0.000000000 seconds sys
After fix it works:
$ ./perf stat -e instructions -D 100 sleep 2
Events disabled

404,214 instructions

capability: just use a 'u64' instead of a 'u32[2]' array
Back in 2008 we extended the capability bits from 32 to 64, and we did it by extending the single 32-bit capability word from one word to an array of two words. It was then obfuscated by hiding the "2" behind two macro expansions, with the reasoning being that maybe it gets extended further some day. That reasoning may have been valid at the time, but the last thing we want to do is to extend the capability set any more. And the array of values not only causes source code oddities (with loops to deal with it), but also results in worse code generation. It's a lose-lose situation. So just change the 'u32[2]' into a 'u64' and be done with it. We still have to deal with the fact that the user space interface is designed around an array of these 32-bit values, but that was the case before too, since the array layouts were different (ie user space doesn't use an array of 32-bit values for individual capability masks, but an array of 32-bit slices of multiple masks). So that marshalling of data is actually simplified too, even if it does remain somewhat obscure and odd. This was all triggered by my reaction to the new "cap_isidentical()" introduced recently. By just using a saner data structure, it went from unsigned __capi; CAP_FOR_EACH_U32(__capi) { if (a.cap[__capi] != b.cap[__capi]) return false; } return true; to just being return a.val == b.val; instead. Which is rather more obvious both to humans and to compilers.

selftests: nft_nat: ensuring the listening side is up before starting the client
The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.
Before the fix:

ARM:
- Provide a virtual cache topology to the guest to avoid inconsistencies with migration on heterogenous systems. Non secure software has no practical need to traverse the caches by set/way in the first place. - Add support for taking stage-2 access faults in parallel. This was an accidental omission in the original parallel faults implementation, but should provide a marginal improvement to machines w/o FEAT_HAFDBS (such as hardware from the fruit company). - A preamble to adding support for nested virtualization to KVM, including vEL2 register state, rudimentary nested exception handling and masking unsupported features for nested guests. - Fixes to the PSCI relay that avoid an unexpected host SVE trap when resuming a CPU when running pKVM. - VGIC maintenance interrupt support for the AIC - Improvements to the arch timer emulation, primarily aimed at reducing the trap overhead of running nested. - Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the interest of CI systems. - Avoid VM-wide stop-the-world operations when a vCPU accesses its own redistributor. - Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions in the host. - Aesthetic and comment/kerneldoc fixes - Drop the vestiges of the old Columbia mailing list and add [Oliver] as co-maintainer This also drags in arm64's 'for-next/sme2' branch, because both it and the PSCI relay changes touch the EL2 initialization code. RISC-V: - Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE - Correctly place the guest in S-mode after redirecting a trap to the guest - Redirect illegal instruction traps to guest - SBI PMU support for guest s390: - Two patches sorting out confusion between virtual and physical addresses, which currently are the same on s390. - A new ioctl that performs cmpxchg on guest memory - A few fixes x86: - Change tdp_mmu to a read-only parameter - Separate TDP and shadow MMU page fault paths - Enable Hyper-V invariant TSC control - Fix a variety of APICv and AVIC bugs, some of them real-world, some of them affecting architecurally legal but unlikely to happen in practice - Mark APIC timer as expired if its in one-shot mode and the count underflows while the vCPU task was being migrated - Advertise support for Intel's new fast REP string features - Fix a double-shootdown issue in the emergency reboot code - Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give SVM similar treatment to VMX - Update Xen's TSC info CPUID sub-leaves as appropriate - Add support for Hyper-V's extended hypercalls, where "support" at this point is just forwarding the hypercalls to userspace - Clean up the kvm->lock vs. kvm->srcu sequences when updating the PMU and MSR filters - One-off fixes and cleanups - Fix and cleanup the range-based TLB flushing code, used when KVM is running on Hyper-V - Add support for filtering PMU events using a mask. If userspace wants to restrict heavily what events the guest can use, it can now do so without needing an absurd number of filter entries - Clean up KVM's handling of "PMU MSRs to save", especially when vPMU support is disabled - Add PEBS support for Intel Sapphire Rapids - Fix a mostly benign overflow bug in SEV's send|receive_update_data() - Move several SVM-specific flags into vcpu_svm x86 Intel: - Handle NMI VM-Exits before leaving the noinstr region - A few trivial cleanups in the VM-Enter flows - Stop enabling VMFUNC for L1 purely to document that KVM doesn't support EPTP switching (or any other VM function) for L1 - Fix a crash when using eVMCS's enlighted MSR bitmaps Generic: - Clean up the hardware enable and initialization flow, which was scattered around multiple arch-specific hooks. Instead, just let the arch code call into generic code.

With this update we can now parse / update the CXL memory layout, and report events / errors from devices. This is a precursor for the CXL subsystem to handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that for DDR-attached-DRAM is handled by the EDAC driver where it maps system physical address events to a field-replaceable-unit (FRU / endpoint device). In general, CXL has the potential to standardize what has historically been a pile of memory-controller-specific error handling logic. Another change of note is the default policy for handling RAM-backed device-dax instances. Previously the default access mode was "device", mmap(2) a device special file to access memory. The new default is "kmem" where the address range is assigned to the core-mm via add_memory_driver_managed(). This saves typical users from wondering why their platform memory is not visible via free(1) and stuck behind a device-file. At the same time it allows expert users to deploy policy to, for example, get dedicated access to high performance memory, or hide low performance memory from general purpose kernel allocations. This affects not only CXL, but also systems with high-bandwidth-memory that platform-firmware tags with the EFI_MEMORY_SP (special purpose) designation. Summary: - CXL RAM region enumeration: instantiate 'struct cxl_region' objects for platform firmware created memory regions - CXL RAM region provisioning: complement the existing PMEM region creation support with RAM region support - "Soft Reservation" policy change: Online (memory hot-add) soft-reserved memory (EFI_MEMORY_SP) by default, but still allow for setting aside such memory for dedicated access via device-dax. - CXL Events and Interrupts: Takeover CXL event handling from platform-firmware (ACPI calls this CXL Memory Error Reporting) and export CXL Events via Linux Trace Events. - Convey CXL _OSC results to drivers: Similar to PCI, let the CXL subsystem interrogate the result of CXL _OSC negotiation. - Emulate CXL DVSEC Range Registers as "decoders": Allow for first-generation devices that pre-date the definition of the CXL HDM Decoder Capability to translate the CXL DVSEC Range Registers into 'struct cxl_decoder' objects. - Set timestamp: Per spec, set the device timestamp in case of hotplug, or if platform-firwmare failed to set it. - General fixups: linux-next build issues, non-urgent fixes for pre-production hardware, unit test fixes, spelling and debug message improvements" * tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (66 commits) dax/kmem: Fix leak of memory-hotplug resources cxl/mem: Add kdoc param for event log driver state cxl/trace: Add serial number to trace points cxl/trace: Add host output to trace points cxl/trace: Standardize device information output cxl/pci: Remove locked check for dvsec_range_allowed() cxl/hdm: Add emulation when HDM decoders are not committed cxl/hdm: Create emulated cxl_hdm for devices that do not have HDM decoders cxl/hdm: Emulate HDM decoder from DVSEC range registers cxl/pci: Refactor cxl_hdm_decode_init() cxl/port: Export cxl_dvsec_rr_decode() to cxl_port cxl/pci: Break out range register decoding from cxl_hdm_decode_init() cxl: add RAS status unmasking for CXL cxl: remove unnecessary calling of pci_enable_pcie_error_reporting() dax/hmem: build hmem device support as module if possible dax: cxl: add CXL_REGION dependency cxl: avoid returning uninitialized error code cxl/pmem: Fix nvdimm registration races cxl/mem: Fix UAPI command comment cxl/uapi: Tag commands from cxl_query_cmd() ... |

Chuck run into an issue with a single-element attr-set which
only has an attr with value of 0. The search for max attr in
a struct records attrs with value larger than 0 only (max_val
is set to 0 at the start). Adjust the comparison, alternatively
max_val could be init'ed to -1. Somehow picking the last attr
of a value seems like a good idea in general.

This enables much more accurate profiles than when using the regular 'perf record -e cycles' (the default) when the workload lasts for very short periods (<10ms). - .plt symbol handling improvements, better handling IBT (in the past MPX) done in the context of decoding Intel PT processor traces, IFUNC symbols on x86_64, static executables, understanding .plt.got symbols on x86_64. - Add a 'perf test' to test symbol resolution, part of the .plt improvements series, this tests things like symbol size in contexts where only the symbol start is available (kallsyms), etc. - Better handle auxtrace/Intel PT data when using pipe mode (perf record sleep 1|perf report). - Fix symbol lookup with kcore with multiple segments match stext, getting the symbol resolution to just show DSOs as unknown. ARM: - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace Macrocell v4). - Ensure ARM64 CoreSight timestamps don't go backwards. - Document that ARM64 SPE (Statistical Profiling Extension) is used with 'perf c2c/mem'. - Add raw decoding for ARM64 SPEv1.2 previous branch address. - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1, TLB, cache, branch, PE utilization and instruction mix metrics. - Update decoder code for OpenCSD version 1.4, on ARM64 systems. - Fix command line auto-complete of CPU events on aarch64. perf test/bench: - Switch basic BPF filtering test to use syscall tracepoint to avoid the variable number of probes inserted when using the previous probe point (do_epoll_wait) that happens on different CPU architectures. - Fix DWARF unwind test by adding non-inline to expected function in a backtrace. - Use 'grep -c' where the longer form 'grep | wc -l' was being used. - Add getpid and execve benchmarks to 'perf bench syscall'. Miscellaneous: - Avoid d3-flame-graph package dependency in 'perf script flamegraph', making this feature more generally available. - Add JSON metric events to present CPI stall cycles in Power10. - Assorted improvements/refactorings on the JSON metrics parsing code. Build: - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked, as several tests use tracepoints, those should be skipped. - More fallout fixes for the removal of tools/lib/traceevent/. - Fix build error when linking with libpfm.

perf inject: Fix --buildid-all not to eat up MMAP2
When MMAP2 has the PERF_RECORD_MISC_MMAP_BUILD_ID flag, it means the
record already has the build-id info. So it marks the DSO as hit, to
skip if the same DSO is not processed if it happens to miss the build-id
later.
But it missed to copy the MMAP2 record itself so it'd fail to symbolize
samples for those regions.
For example, the following generates 249 MMAP2 events.
$ perf record --buildid-mmap -o- true | perf report --stat -i- | grep MMAP2
MMAP2 events: 249 (86.8%)
Adding perf inject should not change the number of events like this
$ perf record --buildid-mmap -o- true | perf inject -b | \
> perf report --stat -i- | grep MMAP2
MMAP2 events: 249 (86.5%)
But when --buildid-all is used, it eats most of the MMAP2 events.
$ perf record --buildid-mmap -o- true | perf inject -b --buildid-all | \
> perf report --stat -i- | grep MMAP2
MMAP2 events: 1 ( 2.5%)
With this patch, it shows the original number now.
$ perf record --buildid-mmap -o- true | perf inject -b --buildid-all | \
> perf report --stat -i- | grep MMAP2
MMAP2 events: 249 (86.5%)
Committer testing:
Before:
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf inject -b | perf report --stat -i- | grep MMAP2
MMAP2 events: 58 (36.2%)
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf report --stat -i- | grep MMAP2
MMAP2 events: 58 (36.2%)
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf inject -b --buildid-all | perf report --stat -i- | grep MMAP2
MMAP2 events: 2 ( 1.9%)
$
After:
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf inject -b | perf report --stat -i- | grep MMAP2
MMAP2 events: 58 (29.3%)
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf report --stat -i- | grep MMAP2
MMAP2 events: 58 (34.3%)
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf inject -b --buildid-all | perf report --stat -i- | grep MMAP2
MMAP2 events: 58 (38.4%)

WARNING: stack going in the wrong direction? at __sys_setsockopt+0x2c6/0x5b0 net/socket.c:2271
And a KASAN warning:
BUG: KASAN: stack-out-of-bounds in unwind_next_frame (arch/x86/include/asm/ptrace.h:136 arch/x86/kernel/unwind_orc.c:455)
It turns out the 'signal' bit isn't getting propagated from the unwind

This shrinks instruction by 16 bytes and brings it down to 128. struct instruction { - struct list_head list; /* 0 16 */ - struct hlist_node hash; /* 16 16 */ - struct list_head call_node; /* 32 16 */ - struct section * sec; /* 48 8 */ - long unsigned int offset; /* 56 8 */ - /* --- cacheline 1 boundary (64 bytes) --- */ - long unsigned int immediate; /* 64 8 */ - unsigned int len; /* 72 4 */ - u8 type; /* 76 1 */ - - /* Bitfield combined with previous fields */ + struct hlist_node hash; /* 0 16 */ + struct list_head call_node; /* 16 16 */ + struct section * sec; /* 32 8 */ + long unsigned int offset; /* 40 8 */ + long unsigned int immediate; /* 48 8 */ + u8 len; /* 56 1 */ + u8 prev_len; /* 57 1 */ + u8 type; /* 58 1 */ + s8 instr; /* 59 1 */ + u32 idx:8; /* 60: 0 4 */ + u32 dead_end:1; /* 60: 8 4 */ + u32 ignore:1; /* 60: 9 4 */ + u32 ignore_alts:1; /* 60:10 4 */ + u32 hint:1; /* 60:11 4 */ + u32 save:1; /* 60:12 4 */ + u32 restore:1; /* 60:13 4 */ + u32 retpoline_safe:1; /* 60:14 4 */ + u32 noendbr:1; /* 60:15 4 */ + u32 entry:1; /* 60:16 4 */ + u32 visited:4; /* 60:17 4 */ + u32 no_reloc:1; /* 60:21 4 */ - u16 dead_end:1; /* 76: 8 2 */ - u16 ignore:1; /* 76: 9 2 */ - u16 ignore_alts:1; /* 76:10 2 */ - u16 hint:1; /* 76:11 2 */ - u16 save:1; /* 76:12 2 */ - u16 restore:1; /* 76:13 2 */ - u16 retpoline_safe:1; /* 76:14 2 */ - u16 noendbr:1; /* 76:15 2 */ - u16 entry:1; /* 78: 0 2 */ - u16 visited:4; /* 78: 1 2 */ - u16 no_reloc:1; /* 78: 5 2 */ + /* XXX 10 bits hole, try to pack */ - /* XXX 2 bits hole, try to pack */ - /* Bitfield combined with next fields */ - - s8 instr; /* 79 1 */ - struct alt_group * alt_group; /* 80 8 */ - struct instruction * jump_dest; /* 88 8 */ - struct instruction * first_jump_src; /* 96 8 */ + /* --- cacheline 1 boundary (64 bytes) --- */ + struct alt_group * alt_group; /* 64 8 */ + struct instruction * jump_dest; /* 72 8 */ + struct instruction * first_jump_src; /* 80 8 */ union { - struct symbol * _call_dest; /* 104 8 */ - struct reloc * _jump_table; /* 104 8 */ - }; /* 104 8 */ - struct alternative * alts; /* 112 8 */ - struct symbol * sym; /* 120 8 */ - /* --- cacheline 2 boundary (128 bytes) --- */ - struct stack_op * stack_ops; /* 128 8 */ - struct cfi_state * cfi; /* 136 8 */ + struct symbol * _call_dest; /* 88 8 */ + struct reloc * _jump_table; /* 88 8 */ + }; /* 88 8 */ + struct alternative * alts; /* 96 8 */ + struct symbol * sym; /* 104 8 */ + struct stack_op * stack_ops; /* 112 8 */ + struct cfi_state * cfi; /* 120 8 */ - /* size: 144, cachelines: 3, members: 28 */ - /* sum members: 142 */ - /* sum bitfield members: 14 bits, bit holes: 1, sum bit holes: 2 bits */ - /* last cacheline: 16 bytes */ + /* size: 128, cachelines: 2, members: 29 */ + /* sum members: 124 */ + /* sum bitfield members: 22 bits, bit holes: 1, sum bit holes: 10 bits */ }; pre: 5:38.18 real, 213.25 user, 124.90 sys, 23449040 mem post: 5:03.34 real, 210.75 user, 88.80 sys, 20241232 mem Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Ingo Molnar <mingo@kernel.org> Acked-by: Josh Poimboeuf <jpoimboe@kernel.org> Tested-by: Nathan Chancellor <nathan@kernel.org> # build only Tested-by: Thomas Weißschuh <linux@weissschuh.net> # compile and run Link: https://lore.kernel.org/r/20230208172245.851307606@infradead.org |

selftests/bpf: Tests for uninitialized stack reads
Three testcases to make sure that stack reads from uninitialized locations are accepted by verifier when executed in privileged mode: - read from a fixed offset; - read from a variable offset; - passing a pointer to stack to a helper converts STACK_INVALID to STACK_MISC.

bpf: Allow reads from uninit stack
This commits updates the following functions to allow reads from uninitialized stack locations when env->allow_uninit_stack option is enabled: - check_stack_read_fixed_off() - check_stack_range_initialized(), called from: - check_stack_read_var_off() - check_helper_mem_access() Such change allows to relax logic in stacksafe() to treat STACK_MISC and STACK_INVALID in a same way and make the following stack slot configurations equivalent: | Cached state | Current state | | stack slot | stack slot | |------------------+------------------| | STACK_INVALID or | STACK_INVALID or | | STACK_MISC | STACK_SPILL or | | | STACK_MISC or | | | STACK_ZERO or | | | STACK_DYNPTR | This leads to significant verification speed gains (see below). The idea was suggested by Andrii Nakryiko [1] and initial patch was created by Alexei Starovoitov [2]. Currently the env->allow_uninit_stack is allowed for programs loaded by users with CAP_PERFMON or CAP_SYS_ADMIN capabilities. A number of test cases from verifier/*.c were expecting uninitialized stack access to be an error. These test cases were updated to execute in unprivileged mode (thus preserving the tests). The test progs/test_global_func10.c expected "invalid indirect read from stack" error message because of the access to uninitialized memory region. This error is no longer possible in privileged mode. The test is updated to provoke an error "invalid indirect access to stack" because of access to invalid stack address (such error is not verified by progs/test_global_func*.c series of tests). The following tests had to be removed because these can't be made unprivileged: - verifier/sock.c: - "sk_storage_get(map, skb->sk, &stack_value, 1): partially init stack_value" BPF_PROG_TYPE_SCHED_CLS programs are not executed in unprivileged mode. - verifier/var_off.c: - "indirect variable-offset stack access, max_off+size > max_initialized" - "indirect variable-offset stack access, uninitialized" These tests verify that access to uninitialized stack values is detected when stack offset is not a constant. However, variable stack access is prohibited in unprivileged mode, thus these tests are no longer valid. * * * Here is veristat log comparing this patch with current master on a set of selftest binaries listed in tools/testing/selftests/bpf/veristat.cfg and cilium BPF binaries (see [3]): $ ./veristat -e file,prog,states -C -f 'states_pct<-30' master.log current.log File Program States (A) States (B) States (DIFF) -------------------------- -------------------------- ---------- ---------- ---------------- bpf_host.o tail_handle_ipv6_from_host 349 244 -105 (-30.09%) bpf_host.o tail_handle_nat_fwd_ipv4 1320 895 -425 (-32.20%) bpf_lxc.o tail_handle_nat_fwd_ipv4 1320 895 -425 (-32.20%) bpf_sock.o cil_sock4_connect 70 48 -22 (-31.43%) bpf_sock.o cil_sock4_sendmsg 68 46 -22 (-32.35%) bpf_xdp.o tail_handle_nat_fwd_ipv4 1554 803 -751 (-48.33%) bpf_xdp.o tail_lb_ipv4 6457 2473 -3984 (-61.70%) bpf_xdp.o tail_lb_ipv6 7249 3908 -3341 (-46.09%) pyperf600_bpf_loop.bpf.o on_event 287 145 -142 (-49.48%) strobemeta.bpf.o on_event 15915 4772 -11143 (-70.02%) strobemeta_nounroll2.bpf.o on_event 17087 3820 -13267 (-77.64%) xdp_synproxy_kern.bpf.o syncookie_tc 21271 6635 -14636 (-68.81%) xdp_synproxy_kern.bpf.o syncookie_xdp 23122 6024 -17098 (-73.95%) -------------------------- -------------------------- ---------- ---------- ---------------- Note: I limited selection by states_pct<-30%. Inspection of differences in pyperf600_bpf_loop behavior shows that the following patch for the test removes almost all differences: - a/tools/testing/selftests/bpf/progs/pyperf.h + b/tools/testing/selftests/bpf/progs/pyperf.h @ -266,8 +266,8 @ int __on_event(struct bpf_raw_tracepoint_args *ctx) } if (event->pthread_match || !pidData->use_tls) { - void* frame_ptr; - FrameData frame; + void* frame_ptr = 0; + FrameData frame = {}; Symbol sym = {}; int cur_cpu = bpf_get_smp_processor_id(); W/o this patch the difference comes from the following pattern (for different variables): static bool get_frame_data(... FrameData *frame ...) { ... bpf_probe_read_user(&frame->f_code, ...); if (!frame->f_code) return false; ... bpf_probe_read_user(&frame->co_name, ...); if (frame->co_name) ...; } int __on_event(struct bpf_raw_tracepoint_args *ctx) { FrameData frame; ... get_frame_data(... &frame ...) // indirectly via a bpf_loop & callback ... } SEC("raw_tracepoint/kfree_skb") int on_event(struct bpf_raw_tracepoint_args* ctx) { ... ret |= __on_event(ctx); ret |= __on_event(ctx); ... } With regards to value `frame->co_name` the following is important: - Because of the conditional `if (!frame->f_code)` each call to __on_event() produces two states, one with `frame->co_name` marked as STACK_MISC, another with it as is (and marked STACK_INVALID on a first call). - The call to bpf_probe_read_user() does not mark stack slots corresponding to `&frame->co_name` as REG_LIVE_WRITTEN but it marks these slots as BPF_MISC, this happens because of the following loop in the check_helper_call(): for (i = 0; i < meta.access_size; i++) { err = check_mem_access(env, insn_idx, meta.regno, i, BPF_B, BPF_WRITE, -1, false); if (err) return err; } Note the size of the write, it is a one byte write for each byte touched by a helper. The BPF_B write does not lead to write marks for the target stack slot. - Which means that w/o this patch when second __on_event() call is verified `if (frame->co_name)` will propagate read marks first to a stack slot with STACK_MISC marks and second to a stack slot with STACK_INVALID marks and these states would be considered different.

perf test: Fix offcpu test prev_state check
On Fedora 36, the 'perf record' offcpu profiling tests are failing. It was because the BPF checks the prev task's state being S or D but actually it has more bits set.

Networking changes for 6.3.
Core ---- - Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use. - Introduce sysctl to set default RPS configuration for new netdevs. - Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols --------- - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF --- - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter --------- - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt. races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API ---------- - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration.

Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols: - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF: - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter: - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API: - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration.

arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1.

RCU pull request for v6.3
This pull request contains the following branches: doc.2023.01.05a: Documentation updates. fixes.2023.01.23a: Miscellaneous fixes, perhaps most notably: o Throttling callback invocation based on the number of callbacks that are now ready to invoke instead of on the total number of callbacks. o Several patches that suppress false-positive boot-time diagnostics, for example, due to lockdep not yet being initialized. o Make expedited RCU CPU stall warnings dump stacks of any tasks that are blocking the stalled grace period. (Normal RCU CPU stall warnings have doen this for mnay years.) o Lazy-callback fixes to avoid delays during boot, suspend, and resume. (Note that lazy callbacks must be explicitly enabled, so this should not (yet) affect production use cases.) kvfree.2023.01.03a: Cause kfree_rcu() and friends to take advantage of polled grace periods, thus reducing memory footprint by almost two orders of magnitude, admittedly on a microbenchmark. This series also begins the transition from kfree_rcu(p) to kfree_rcu_mightsleep(p). This transition was motivated by bugs where kfree_rcu(p), which can block, was typed instead of the intended kfree_rcu(p, rh). srcu.2023.01.03a: SRCU updates, perhaps most notably fixing a bug that causes SRCU to fail when booted on a system with a non-zero boot CPU. This surprising situation actually happens for kdump kernels on the powerpc architecture. It also adds an srcu_down_read() and srcu_up_read(), which act like srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side critical section to be handed off from one task to another. srcu-always.2023.02.02a: Cleans up the now-useless SRCU Kconfig option. There are a few more commits that are not yet acked or pulled into maintainer trees, and these will be in a pull request for a later merge window. tasks.2023.01.03a: RCU-tasks updates, perhaps most notably these fixes: o A strange interaction between PID-namespace unshare and the RCU-tasks grace period that results in a low-probability but very real hang. o A race between an RCU tasks rude grace period on a single-CPU system and CPU-hotplug addition of the second CPU that can result in a too-short grace period. o A race between shrinking RCU tasks down to a single callback list and queuing a new callback to some other CPU, but where that queuing is delayed for more than an RCU grace period. This can result in that callback being stranded on the non-boot CPU. torture.2023.01.05a: Torture-test updates and fixes. torturescript.2023.01.03a: Torture-test scripting updates and fixes. stall.2023.01.09a: Provide additional RCU CPU stall-warning information in kernels built with CONFIG_RCU_CPU_STALL_CPUTIME=y, and restore the full five-minute timeout limit for expedited RCU CPU stall warnings. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmPq29UTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jAhVEACEAKJY1VJ9IUqz7CwzAYkzgRJfiygh oDUXmlqtm6ew9pr2GdLUVCVsUSldzBc0K7Djb/G1niv4JPs+v7YwupIV33+UbStU Qxt6ztTdxc4lKospLm1+2vF9ZdzVEmiP4wVCc4iDarv5FM3FpWSTNc8+L7qmlC+X myjv+GqMTxkXZBvYJOgJGFjDwN8noTd7Fr3mCCVLFm3PXMDa7tcwD6HRP5AqD2N8 qC5M6LEqepKVGmz0mYMLlSN1GPaqIsEcexIFEazRsPEivPh/iafyQCQ/cqxwhXmV vEt7u+dXGZT/oiDq9cJ+/XRDS2RyKIS6dUE14TiiHolDCn1ONESahfA/gXWKykC2 BaGPfjWXrWv/hwbeZ+8xEdkAvTIV92tGpXir9Fby1Z5PjP3balvrnn6hs5AnQBJb NdhRPLzy/dCnEF+CweAYYm1qvTo8cd5nyiNwBZHn7rEAIu3Axrecag1rhFl3AJ07 cpVMQXZtkQVa2X8aIRTUC+ijX6yIqNaHlu0HqNXgIUTDzL4nv5cMjOMzpNQP9/dZ FwAMZYNiOk9IlMiKJ8ZiVcxeiA8ouIBlkYM3k6vGrmiONZ7a/EV/mSHoJqI8bvqr AxUIJ2Ayhg3bxPboL5oKgCiLql0A7ZVvz6quX6McitWGMgaSvel1fDzT3TnZd41e 4AFBFd/+VedUGg== =bBYK -----END PGP SIGNATURE----- Merge tag 'rcu.2023.02.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Documentation updates - Miscellaneous fixes, perhaps most notably: - Throttling callback invocation based on the number of callbacks that are now ready to invoke instead of on the total number of callbacks - Several patches that suppress false-positive boot-time diagnostics, for example, due to lockdep not yet being initialized - Make expedited RCU CPU stall warnings dump stacks of any tasks that are blocking the stalled grace period.
