* objtool: Add STACK_FRAME_NON_STANDARD() macroJosh Poimboeuf2022-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | Add a new macro, STACK_FRAME_NON_STANDARD(), which is used to denote a function which does something unusual related to its stack frame. Use of the macro prevents objtool from emitting a false positive warning.

* bpf: get rid of pure_initcall dependency to enable jitsDaniel Borkmann2022-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | commit fa9dd599b4dae841924b022768354cfde9affecb upstream. Having a pure_initcall() callback just to permanently enable BPF JITs under CONFIG_BPF_JIT_ALWAYS_ON is unnecessary and could leave a small race window in future where JIT is still disabled on boot. Since we know about the setting at compilation time anyway, just initialize it properly there. Also consolidate all the individual bpf_jit_enable variables into a single one and move them under one location. Moreover, don't allow for setting unspecified garbage values on them.

* arm64: bpf: implement bpf_tail_call() helperZi Shen Lim2022-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for JMP_CALL_X (tail call) introduced by commit 04fd61ab36ec ("bpf: allow bpf programs to tail-call other bpf programs"). bpf_tail_call() arguments: ctx - context pointer passed to next program array - pointer to map which type is BPF_MAP_TYPE_PROG_ARRAY index - index inside array that selects specific program to run In this implementation arm64 JIT jumps into callee program after prologue, so callee program reuses the same stack. For tail_call_cnt, we use the callee-saved R26 (which was already saved/restored but previously unused by JIT). With this patch a tail call generates the following code on arm64: if (index >= array->map.max_entries) goto out; 34: mov x10, #0x10 // #16 38: ldr w10, [x1,x10] 3c: cmp w2, w10 40: b.ge 0x0000000000000074 if (tail_call_cnt > MAX_TAIL_CALL_CNT) goto out; tail_call_cnt++; 44: mov x10, #0x20 // #32 48: cmp x26, x10 4c: b.gt 0x0000000000000074 50: add x26, x26, #0x1 prog = array->ptrs[index]; if (prog == NULL) goto out; 54: mov x10, #0x68 // #104 58: ldr x10, [x1,x10] 5c: ldr x11, [x10,x2] 60: cbz x11, 0x0000000000000074 goto *(prog->bpf_func + prologue_size); 64: mov x10, #0x20 // #32 68: ldr x10, [x11,x10] 6c: add x10, x10, #0x20 70: br x10 74: Signed-off-by: Zi Shen Lim <zlim.lnx@gmail.com> Signed-off-by: David S.

* bpf: arm64: remove callee-save registers use for tmp registersYang Shi2022-04-19
| | | | | | | | | | | | | | | | | | In the current implementation of ARM64 eBPF JIT, R23 and R24 are used for tmp registers, which are callee-saved registers. This leads to variable size of JIT prologue and epilogue. The latest blinding constant change prefers to constant size of prologue and epilogue. AAPCS reserves R9 ~ R15 for temp registers which not need to be saved/restored during function call. So, replace R23 and R24 to R10 and R11, and remove tmp_used flag to save 2 instructions for some jited BPF program.

* bpf, arm64: add support for constant blindingDaniel Borkmann2022-04-19
| | | | | | | | | | | | | | | This patch adds recently added constant blinding helpers into the arm64 eBPF JIT. In the bpf_int_jit_compile() path, requirements are to utilize bpf_jit_blind_constants()/bpf_jit_prog_release_other() pair for rewriting the program into a blinded one, and to map the BPF_REG_AX register to a CPU register. The mapping is on x9.

* arm64: bpf: add extra pass to handle faulty codegenZi Shen Lim2022-04-19
| | | | | | | | | | | | | | | | | | Code generation functions in arch/arm64/kernel/insn.c previously BUG_ON invalid parameters. Following change of that behavior, now we need to handle the error case where AARCH64_BREAK_FAULT is returned. Instead of error-handling on every emit() in JIT, we add a new validation pass at the end of JIT compilation. There's no point in running JITed code at run-time only to trap due to AARCH64_BREAK_FAULT. Instead, we drop this failed JIT compilation and allow the system to gracefully fallback on the BPF interpreter.

* perf/core: Set event's default ::overflow_handler()Wang Nan2022-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set a default event->overflow_handler in perf_event_alloc() so don't need to check event->overflow_handler in __perf_event_overflow(). Following commits can give a different default overflow_handler. Initial idea comes from Peter: http://lkml.kernel.org/r/20130708121557.GA17211@twins.programming.kicks-ass.net Since the default value of event->overflow_handler is not NULL, existing 'if (!overflow_handler)' checks need to be changed. is_default_overflow_handler() is introduced for this. No extra performance overhead is introduced into the hot path because in the original code we still need to read this handler from memory. A conditional branch is avoided so actually we remove some instructions.

* bpf: fix bpf_tail_call() x64 JITAlexei Starovoitov2022-04-19
| | | | | | | | | | | | | | | | | | | | | | | | [ upstream commit 90caccdd8cc0215705f18b92771b449b01e2474a ] - bpf prog_array just like all other types of bpf array accepts 32-bit index. Clarify that in the comment. - fix x64 JIT of bpf_tail_call which was incorrectly loading 8 instead of 4 bytes - tighten corresponding check in the interpreter to stay consistent The JIT bug can be triggered after introduction of BPF_F_NUMA_NODE flag in commit 96eabe7a40aa in 4.14. Before that the map_flags would stay zero and though JIT code is wrong it will check bounds correctly. Hence two fixes tags. All other JITs don't have this problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default remains 127, which is good for most cases, and not even hit most of the time, but then for some cases, as reported by Brendan, 1024+ deep frames are appearing on the radar for things like groovy, ruby. And in some workloads putting a _lower_ cap on this may make sense. One that is per event still needs to be put in place tho. The new file is: # cat /proc/sys/kernel/perf_event_max_stack 127 Chaging it: # echo 256 > /proc/sys/kernel/perf_event_max_stack # cat /proc/sys/kernel/perf_event_max_stack 256 But as soon as there is some event using callchains we get: # echo 512 > /proc/sys/kernel/perf_event_max_stack -bash: echo: write error: Device or resource busy # Because we only allocate the callchain percpu data structures when there is a user, which allows for changing the max easily, its just a matter of having no callchain users at that point.

* bpf: move clearing of A/X into classic to eBPF migration prologueDaniel Borkmann2022-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in the days where eBPF (or back then "internal BPF" ;->) was not exposed to user space, and only the classic BPF programs internally translated into eBPF programs, we missed the fact that for classic BPF A and X needed to be cleared. It was fixed back then via 83d5b7ef99c9 ("net: filter: initialize A and X registers"), and thus classic BPF specifics were added to the eBPF interpreter core to work around it. This added some confusion for JIT developers later on that take the eBPF interpreter code as an example for deriving their JIT. F.e. in f75298f5c3fe ("s390/bpf: clear correct BPF accumulator register"), at least X could leak stack memory. Furthermore, since this is only needed for classic BPF translations and not for eBPF (verifier takes care that read access to regs cannot be done uninitialized), more complexity is added to JITs as they need to determine whether they deal with migrations or native eBPF where they can just omit clearing A/X in their prologue and thus reduce image size a bit, see f.e. cde66c2d88da ("s390/bpf: Only clear A and X for converted BPF programs"). In other cases (x86, arm64), A and X is being cleared in the prologue also for eBPF case, which is unnecessary. Lets move this into the BPF migration in bpf_convert_filter() where it actually belongs as long as the number of eBPF JITs are still few. It can thus be done generically; allowing us to remove the quirk from __bpf_prog_run() and to slightly reduce JIT image size in case of eBPF, while reducing code duplication on this matter in current(/future) eBPF JITs.

However, its backported version in stable (commit ba7f1c934f2e ("KVM: x86: work around leak of uninitialized stack contents")) applied the change in `emulator_write_std` instead. This patch moves the memset instruction back to `kvm_write_guest_virt_system`.

Currently if z/VM guest is allowed to retrieve hypervisor performance data globally for all guests (privilege class B) the query is formed in a way to include all guests but the group name is left empty. This leads to that z/VM guests which have access control group set not being included in the results (even local vm). Change the query group identifier from empty to "any" to retrieve information about all guests from any groups (or without a group set).

If the fault handler is disabled, we immediately call do_page_fault(). It then calls faulthandler_disabled(). If disabled, do_page_fault() attempts to fixup the exception by jumping to no_context: no_context: if (!user_mode(regs) && fixup_exception(regs)) { return; } parisc_terminate("Bad Address (null pointer deref?)", regs, code, address); Apart from the error messages, the two blocks of code perform the same function. We can avoid two calls to faulthandler_disabled() by a simple revision to the code in handle_interruption(). Note: I didn't try to fix the formatting of this code block.

The naked attribute is known to confuse some old gcc versions when function arguments aren't explicitly listed as inline assembly operands despite the gcc documentation. That resulted in commit 9a40ac86152c ("ARM: 6164/1: Add kto and kfrom to input operands list."). Yet that commit has problems of its own by having assembly operand constraints completely wrong. If the generated code has been OK since then, it is due to luck rather than correctness. So this patch also provides proper assembly operand constraints, and removes two instances of redundant register usages in the implementation while at it. Inspection of the generated code with this patch doesn't show any obvious quality degradation either, so not relying on __naked at all will make the code less fragile, and avoid some issues with clang. The only remaining __naked instances (excluding the kprobes test cases) are exynos_pm_power_up_setup(), tc2_pm_power_up_setup() and cci_enable_port_for_self(. But in the first two cases, only the function address is used by the compiler with no chance of inlining it by mistake, and the third case is called from assembly code only. And the fact that no stack is available when the corresponding code is executed does warrant the __naked usage in those cases.

For some that is an amount of online memory, for s390 and x86 this is the limiting max address. Some memblock api like memblock_enforce_memory_limit() take limit argument and explicitly treat it as the size of online memory, and use __find_max_addr to convert it to an actual max address. Current s390 usage: memblock_enforce_memory_limit(memblock_end_of_DRAM()); yields different results depending on presence of memory holes (offline memory blocks in between online memory). If there are no memory holes limit == max_addr in memblock_enforce_memory_limit() and it does trim online memory and reserved memory regions. With memory holes present it actually does nothing. Since we already use memblock_remove() explicitly to trim online memory regions to potential limit (think mem=, kdump, addressing limits, etc.) drop the usage of memblock_enforce_memory_limit() altogether. Trimming reserved regions should not be required, since we now use memblock_set_current_limit() to limit allocations and any explicit memory reservations above the limit is an actual problem we should not hide.

| | * hugetlbfs: flush TLBs correctly after huge_pmd_unshareNadav Amit2021-12-08

When __unmap_hugepage_range() calls to huge_pmd_unshare() succeed, a TLB flush is missing. This TLB flush must be performed before releasing the i_mmap_rwsem, in order to prevent an unshared PMDs page from being released and reused before the TLB flush took place. Arguably, a comprehensive solution would use mmu_gather interface to batch the TLB flushes and the PMDs page release, however it is not an easy solution: (1) try_to_unmap_one() and try_to_migrate_one() also call huge_pmd_unshare() and they cannot use the mmu_gather interface; and (2) deferring the release of the page reference for the PMDs page until after i_mmap_rwsem is dropeed can confuse huge_pmd_unshare() into thinking PMDs are shared when they are not. Fix __unmap_hugepage_range() by adding the missing TLB flush, and forcing a flush when unshare is successful.

| | * ARM: socfpga: Fix crash with CONFIG_FORTIRY_SOURCETakashi Iwai2021-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 187bea472600dcc8d2eb714335053264dd437172 ] When CONFIG_FORTIFY_SOURCE is set, memcpy() checks the potential buffer overflow and panics. The code in sofcpga bootstrapping contains the memcpy() calls are mistakenly translated as the shorter size, hence it triggers a panic as if it were overflowing. This patch changes the secondary_trampoline and *_end definitions to arrays for avoiding the false-positive crash above.

Patch series "Fixes for ARCH=hexagon allmodconfig", v2. This series fixes some issues noticed with ARCH=hexagon allmodconfig. This patch (of 3): When building ARCH=hexagon allmodconfig, the following errors occur: ERROR: modpost: "__raw_readsl" [drivers/i3c/master/svc-i3c-master.ko] undefined! ERROR: modpost: "__raw_writesl" [drivers/i3c/master/dw-i3c-master.ko] undefined! ERROR: modpost: "__raw_readsl" [drivers/i3c/master/dw-i3c-master.ko] undefined!
