2023-12-19selftests/bpf: add freplace of BTF-unreliable main prog testAndrii Nakryiko
Add a test validating that freplace'ing another main (entry) BPF program fails if the target BPF program doesn't have valid/expected func proto BTF. We extend fexit_bpf2bpf test to allow to specify expected log message for negative test cases (where freplace program is expected to fail to load).

2023-12-19bpf: reuse subprog argument parsing logic for subprog call checksAndrii Nakryiko
Remove duplicated BTF parsing logic when it comes to subprog call check. Instead, use (potentially cached) results of btf_prepare_func_args() to abstract away expectations of each subprog argument in generic terms (e.g., "this is pointer to context", or "this is a pointer to memory of size X"), and then use those simple high-level argument type expectations to validate actual register states to check if they match expectations.

2023-12-19bpf: reuse btf_prepare_func_args() check for main program BTF validationAndrii Nakryiko
Instead of btf_check_subprog_arg_match(), use btf_prepare_func_args() logic to validate "trustworthiness" of main BPF program's BTF information, if it is present. We ignored results of original BTF check anyway, often times producing confusing and ominously-sounding "reg type unsupported for arg#0 function" message, which has no apparent effect on program correctness and verification process. All the -EFAULT returning sanity checks are already performed in check_btf_info_early(), so there is zero reason to have this duplication of logic between btf_check_subprog_call() and btf_check_subprog_arg_match(). Dropping btf_check_subprog_arg_match() simplifies btf_check_func_arg_match() further removing `bool processing_call` flag. One subtle bit that was done by btf_check_subprog_arg_match() was potentially marking main program's BTF as unreliable. We do this explicitly now with a dedicated simple check, preserving the original behavior, but now based on well factored btf_prepare_func_args() logic.

Add testcase for the logic that the verifier tracks the BPF_JNE for regs. The assembly function "reg_not_equal_const()" and "reg_equal_const" that we add is exactly converted from the following case: u32 a = bpf_get_prandom_u32(); u64 b = 0; a %= 8; /* the "a > 0" here will be optimized to "a != 0" */ if (a > 0) { /* now the range of a should be [1, 7] */ bpf_skb_store_bytes(skb, 0, &b, a, 0); } Signed-off-by: Menglong Dong <menglong8.dong@gmail.com> Acked-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/r/20231219134800.1550388-5-menglong8.dong@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2023-12-19perf archive: Add new option '--all' to pack perf.data with DSOsVeronika Molnarova
'perf archive' has limited functionality and people from Red Hat Global Support Services sent a request for a new feature that would pack perf.data file together with an archive with debug symbols created by the command 'perf archive' as customers were being confused and often would forget to send perf.data file with the debug symbols. With this patch 'perf archive' now accepts an option '--all' that generates archive 'perf.all-hostname-date-time.tar.bz2' that holds file 'perf.data' and a sub-tar 'perf.symbols.tar.bz2' with debug symbols. The functionality of the command 'perf archive' was not changed.

2023-12-19kselftest/arm64: Don't probe the current VL for unsupported vector typesMark Brown
The vec-syscfg selftest verifies that setting the VL of the currently tested vector type does not disrupt the VL of the other vector type. To do this it records the current vector length for each type but neglects to guard this with a check for that vector type actually being supported. Add one, using a helper function which we also update all the other instances of this pattern.

2023-12-18Merge tag 'for-netdev' of ↵Jakub Kicinski
https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next Alexei Starovoitov says: ==================== pull-request: bpf-next 2023-12-18 This PR is larger than usual and contains changes in various parts of the kernel. The main changes are: 1) Fix kCFI bugs in BPF, from Peter Zijlstra. End result: all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y. 2) Introduce BPF token object, from Andrii Nakryiko. It adds an ability to delegate a subset of BPF features from privileged daemon (e.g., systemd) through special mount options for userns-bound BPF FS to a trusted unprivileged application. The design accommodates suggestions from Christian Brauner and Paul Moore. Example: $ sudo mkdir -p /sys/fs/bpf/token $ sudo mount -t bpf bpffs /sys/fs/bpf/token \ -o delegate_cmds=prog_load:MAP_CREATE \ -o delegate_progs=kprobe \ -o delegate_attachs=xdp 3) Various verifier improvements and fixes, from Andrii Nakryiko, Andrei Matei. - Complete precision tracking support for register spills - Fix verification of possibly-zero-sized stack accesses - Fix access to uninit stack slots - Track aligned STACK_ZERO cases as imprecise spilled registers. It improves the verifier "instructions processed" metric from single digit to 50-60% for some programs. - Fix verifier retval logic 4) Support for VLAN tag in XDP hints, from Larysa Zaremba. 5) Allocate BPF trampoline via bpf_prog_pack mechanism, from Song Liu. End result: better memory utilization and lower I$ miss for calls to BPF via BPF trampoline. 6) Fix race between BPF prog accessing inner map and parallel delete, from Hou Tao. 7) Add bpf_xdp_get_xfrm_state() kfunc, from Daniel Xu. It allows BPF interact with IPSEC infra. The intent is to support software RSS (via XDP) for the upcoming ipsec pcpu work. Experiments on AWS demonstrate single tunnel pcpu ipsec reaching line rate on 100G ENA nics. 8) Expand bpf_cgrp_storage to support cgroup1 non-attach, from Yafang Shao. 9) BPF file verification via fsverity, from Song Liu. It allows BPF progs get fsverity digest. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (164 commits) bpf: Ensure precise is reset to false in __mark_reg_const_zero() selftests/bpf: Add more uprobe multi fail tests bpf: Fail uprobe multi link with negative offset selftests/bpf: Test the release of map btf s390/bpf: Fix indirect trampoline generation selftests/bpf: Temporarily disable dummy_struct_ops test on s390 x86/cfi,bpf: Fix bpf_exception_cb() signature bpf: Fix dtor CFI cfi: Add CFI_NOSEAL() x86/cfi,bpf: Fix bpf_struct_ops CFI x86/cfi,bpf: Fix bpf_callback_t CFI x86/cfi,bpf: Fix BPF JIT call cfi: Flip headers selftests/bpf: Add test for abnormal cnt during multi-kprobe attachment selftests/bpf: Don't use libbpf_get_error() in kprobe_multi_test selftests/bpf: Add test for abnormal cnt during multi-uprobe attachment bpf: Limit the number of kprobes when attaching program to multiple kprobes bpf: Limit the number of uprobes when attaching program to multiple uprobes bpf: xdp: Register generic_kfunc_set with XDP programs selftests/bpf: utilize string values for delegate_xxx mount options ... ==================== Link: https://lore.kernel.org/r/20231219000520.34178-1-alexei.starovoitov@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-12-18bpf: Ensure precise is reset to false in __mark_reg_const_zero()Andrii Nakryiko
It is safe to always start with imprecise SCALAR_VALUE register. Previously __mark_reg_const_zero() relied on caller to reset precise mark, but it's very error prone and we already missed it in a few places. So instead make __mark_reg_const_zero() reset precision always, as it's a safe default for SCALAR_VALUE. Explanation is basically the same as for why we are resetting (or rather not setting) precision in current state. If necessary, precision propagation will set it to precise correctly. As such, also remove a big comment about forward precision propagation in mark_reg_stack_read() and avoid unnecessarily setting precision to true after reading from STACK_ZERO stack. Again, precision propagation will correctly handle this, if that SCALAR_VALUE register will ever be needed to be precise.

2023-12-18selftests/bpf: Test the release of map btfHou Tao
When there is bpf_list_head or bpf_rb_root field in map value, the free of map btf and the free of map value may run concurrently and there may be use-after-free problem, so add two test cases to demonstrate it. And the use-after-free problem can been easily reproduced by using bpf_next tree and a KASAN-enabled kernel. The first test case tests the racing between the free of map btf and the free of array map. It constructs the racing by releasing the array map in the end after other ref-counter of map btf has been released. To delay the free of array map and make it be invoked after btf_free_rcu() is invoked, it stresses system_unbound_wq by closing multiple percpu array maps before it closes the array map. The second case tests the racing between the free of map btf and the free of inner map. Beside using the similar method as the first one does, it uses bpf_map_delete_elem() to delete the inner map and to defer the release of inner map after one RCU grace period. The reason for using two skeletons is to prevent the release of outer map and inner map in map_in_map_btf.c interfering the release of bpf map in normal_map_btf.c.

2023-12-18tools/counter: add a flexible watch events toolFabrice Gasnier
This adds a new counter tool to be able to test various watch events. A flexible watch array can be populated from command line, each field may be tuned with a dedicated command line sub-option in "--watch" string. Several watch events can be defined, each can have specific watch options, by using "--watch <watch 1 options> --watch <watch 2 options>". Watch options is a comma separated list. It also comes with a simple default watch (to monitor overflow/underflow events), used when no watch parameters are provided. It's equivalent to: counter_watch_events -w comp_count,scope_count,evt_ovf_udf The print_usage() routine proposes another example, from the command line, which generates a 2 elements watch array, to monitor: - overflow underflow events - capture events, on channel 3, that reads read captured data by specifying the component id (capture3_component_id being 7 here).

2023-12-17selftests: mptcp: join: fix subflow_send_ack lookupGeliang Tang
MPC backups tests will skip unexpected sometimes (For example, when compiling kernel with an older version of gcc, such as gcc-8), since static functions like mptcp_subflow_send_ack also be listed in /proc/kallsyms, with a 't' in front of it, not 'T' ('T' is for a global function): > grep "mptcp_subflow_send_ack" /proc/kallsyms 0000000000000000 T __pfx___mptcp_subflow_send_ack 0000000000000000 T __mptcp_subflow_send_ack 0000000000000000 t __pfx_mptcp_subflow_send_ack 0000000000000000 t mptcp_subflow_send_ack In this case, mptcp_lib_kallsyms_doesnt_have "mptcp_subflow_send_ack$" will be false, MPC backups tests will skip. This is not what we expected. The correct logic here should be: if mptcp_subflow_send_ack is not a global function in /proc/kallsyms, do these MPC backups tests. So a 'T' must be added in front of mptcp_subflow_send_ack.
