While at it, I switched the bug table to use relative addresses which reduces the size of the table by half on 64-bit. We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs from HP-UX, which now trigger build-issues with glibc. We can simply remove them.

Those return codes are only defined for the parisc architecture and are leftovers from when we wanted to be HP-UX compatible. They are not returned by any Linux kernel syscall but do trigger problems with the glibc strerrorname_np() and strerror() functions as reported in glibc issue #31080. There is no need to keep them, so simply remove them.

We don't support CRUD-inspired message types in YNL too well. One aspect that currently trips us up is the fact that single message ID can be used in multiple commands (as the response). This leads to duplicate entries in the id-to-string tables: devlink-user.c:19:34: warning: initialized field overwritten [-Woverride-init] 19 | [DEVLINK_CMD_PORT_NEW] = "port-new", | ^~~~~~~~~~ devlink-user.c:19:34: note: (near initialization for ‘devlink_op_strmap[7]’) Fixes tag points at where the code was generated, the "real" problem is that the code generator does not support CRUD.

2023-11-20selftests/bpf: check if max number of bpf_loop iterations is trackedEduard Zingerman1-0/+75

2023-11-20bpf: keep track of max number of bpf_loop callback iterationsEduard Zingerman1-10/+25
In some cases verifier can't infer convergence of the bpf_loop() iteration. E.g. for the following program: static int cb(__u32 idx, struct num_context* ctx) { ctx->i++; return 0; } SEC("?raw_tp") int prog(void *_) { struct num_context ctx = { .i = 0 }; __u8 choice_arr[2] = { 0, 1 }; bpf_loop(2, cb, &ctx, 0); return choice_arr[ctx.i]; } Each 'cb' simulation would eventually return to 'prog' and reach 'return choice_arr[ctx.i]' statement. At which point ctx.i would be marked precise, thus forcing verifier to track multitude of separate states with {.i=0}, {.i=1}, ... at bpf_loop() callback entry. This commit allows "brute force" handling for such cases by limiting number of callback body simulations using 'umax' value of the first bpf_loop() parameter. For this, extend bpf_func_state with 'callback_depth' field. Increment this field when callback visiting state is pushed to states traversal stack. For frame #N it's 'callback_depth' field counts how many times callback with frame depth N+1 had been executed. Use bpf_func_state specifically to allow independent tracking of callback depths when multiple nested bpf_loop() calls are present.

2023-11-20bpf: verify callbacks as if they are called unknown number of timesEduard Zingerman3-14/+60
Prior to this patch callbacks were handled as regular function calls, execution of callback body was modeled exactly once. This patch updates callbacks handling logic as follows: - introduces a function push_callback_call() that schedules callback body verification in env->head stack; - updates prepare_func_exit() to reschedule callback body verification upon BPF_EXIT; - as calls to bpf_*_iter_next(), calls to callback invoking functions are marked as checkpoints; - is_state_visited() is updated to stop callback based iteration when some identical parent state is found. Paths with callback function invoked zero times are now verified first, which leads to necessity to modify some selftests: - the following negative tests required adding release/unlock/drop calls to avoid previously masked unrelated error reports: - cb_refs.c:underflow_prog - exceptions_fail.c:reject_rbtree_add_throw - exceptions_fail.c:reject_with_cp_reference - the following precision tracking selftests needed change in expected log trace: - verifier_subprog_precision.c:callback_result_precise (note: r0 precision is no longer propagated inside callback and I think this is a correct behavior) - verifier_subprog_precision.c:parent_callee_saved_reg_precise_with_callback - verifier_subprog_precision.c:parent_stack_slot_precise_with_callback Reported-by: Andrew Werner <awerner32@gmail.com> Closes: https://lore.kernel.org/bpf/CA+vRuzPChFNXmouzGG+wsy=6eMcfr1mFG0F3g7rbg-sedGKW3w@mail.gmail.com/ Acked-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Eduard Zingerman <eddyz87@gmail.com> Link: https://lore.kernel.org/r/20231121020701.26440-7-eddyz87@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2023-11-20selftests/bpf: fix bpf_loop_bench for new callback verification schemeEduard Zingerman1-5/+8
This is a preparatory change. A follow-up patch "bpf: verify callbacks as if they are called unknown number of times" changes logic for callbacks handling. While previously callbacks were verified as a single function call, new scheme takes into account that callbacks could be executed unknown number of times. This has dire implications for bpf_loop_bench: SEC("fentry/" SYS_PREFIX "sys_getpgid") int benchmark(void *ctx) { for (int i = 0; i < 1000; i++) { bpf_loop(nr_loops, empty_callback, NULL, 0); __sync_add_and_fetch(&hits, nr_loops); } return 0; } W/o callbacks change verifier sees it as a 1000 calls to empty_callback(). However, with callbacks change things become exponential: - i=0: state exploring empty_callback is scheduled with i=0 (a); - i=1: state exploring empty_callback is scheduled with i=1; ... - i=999: state exploring empty_callback is scheduled with i=999; - state (a) is popped from stack; - i=1: state exploring empty_callback is scheduled with i=1; ... Avoid this issue by rewriting outer loop as bpf_loop(). Unfortunately, this adds a function call to a loop at runtime, which negatively affects performance: throughput latency before: 149.919 ± 0.168 M ops/s, 6.670 ns/op after : 137.040 ± 0.187 M ops/s, 7.297 ns/op Acked-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Eduard Zingerman <eddyz87@gmail.com> Link: https://lore.kernel.org/r/20231121020701.26440-4-eddyz87@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2023-11-15selftests/mm: restore number of hugepagesBreno Leitao1-0/+3
The test mm `hugetlb_fault_after_madv` selftest needs one and only one huge page to run, thus it sets `/proc/sys/vm/nr_hugepages` to 1. The problem is that further tests require the previous number of hugepages allocated in order to succeed. Save the number of huge pages before changing it, and restore it once the test finishes, so, further tests could run successfully.

2023-11-09bpf: fix control-flow graph checking in privileged modeAndrii Nakryiko2-6/+9
When BPF program is verified in privileged mode, BPF verifier allows bounded loops. This means that from CFG point of view there are definitely some back-edges. Original commit adjusted check_cfg() logic to not detect back-edges in control flow graph if they are resulting from conditional jumps, which the idea that subsequent full BPF verification process will determine whether such loops are bounded or not, and either accept or reject the BPF program. At least that's my reading of the intent. Unfortunately, the implementation of this idea doesn't work correctly in all possible situations. Conditional jump might not result in immediate back-edge, but just a few unconditional instructions later we can arrive at back-edge. In such situations check_cfg() would reject BPF program even in privileged mode, despite it might be bounded loop. Next patch adds one simple program demonstrating such scenario. To keep things simple, instead of trying to detect back edges in privileged mode, just assume every back edge is valid and let subsequent BPF verification prove or reject bounded loops. Note a few test changes. For unknown reason, we have a few tests that are specified to detect a back-edge in a privileged mode, but looking at their code it seems like the right outcome is passing check_cfg() and letting subsequent verification to make a decision about bounded or not bounded looping. Bounded recursion case is also interesting. The example should pass, as recursion is limited to just a few levels and so we never reach maximum number of nested frames and never exhaust maximum stack depth. But the way that max stack depth logic works today it falsely detects this as exceeding max nested frame count. This patch series doesn't attempt to fix this orthogonal problem, so we just adjust expected verifier failure.

2023-11-09bpf: handle ldimm64 properly in check_cfg()Andrii Nakryiko1-4/+4
ldimm64 instructions are 16-byte long, and so have to be handled appropriately in check_cfg(), just like the rest of BPF verifier does. This has implications in three places: - when determining next instruction for non-jump instructions; - when determining next instruction for callback address ldimm64 instructions (in visit_func_call_insn()); - when checking for unreachable instructions, where second half of ldimm64 is expected to be unreachable; We take this also as an opportunity to report jump into the middle of ldimm64. And adjust few test_verifier tests accordingly.

2023-11-07selftests/bpf: get trusted cgrp from bpf_iter__cgroup directlyChuyi Zhou1-12/+4
Commit f49843afde (selftests/bpf: Add tests for css_task iter combining with cgroup iter) added a test which demonstrates how css_task iter can be combined with cgroup iter. That test used bpf_cgroup_from_id() to convert bpf_iter__cgroup->cgroup to a trusted ptr which is pointless now, since with the previous fix, we can get a trusted cgroup directly from bpf_iter__cgroup.
