1.NUMA感知Zval池化ARM64缓存亲和 大白话百万协程时每个协程都在堆上 emalloc zval跨 NUMA 节点访问导致内存爆炸。每个 NUMA 节点建独立 zval 池协程绑核时按 LLC 共享分组。#includenuma.h#includenumaif.htypedefstruct{_Atomic(void*)free_list;uint8_tpad[56];}zpool_node_t;staticzpool_node_tpools[8];/* 最多8个NUMA节点

同时降频省电。SEC(uprobe/php:zend_jit_compile)intBPF_KPROBE(on_jit){__u64 nowbpf_ktime_get_ns(),*cnt;__u32 k0;cntbpf_map_lookup_elem(jit_rate,k);if(cntnow-*cnt1000000000ULL/100){bpf_override_return(ctx,0);/*

跟着线程不跟协程。把 span 存到协程级 TSRM 储物柜里切换钩子里恢复。typedefstruct{uint8_ttrace_id[16];uint8_tspan_id[8];}otel_ctx_t;__threadotel_ctx_t*cur_otel;voidcoro_otel_save(uint64_tcid){lftsrm_ctx_t*clftsrm_get(cid);memcpy(c-resources[OTEL_RID],cur_otel,sizeof(otel_ctx_t));}voidcoro_otel_restore(uint64_tcid){lftsrm_ctx_t*clftsrm_get(cid);cur_otel(otel_ctx_t*)c-resources[OTEL_RID];/*

哈希。任何环节被篡改最终哈希对不上就拒绝执行。typedefstruct{uint8_tsrc_h[32],op_h[32],mc_h[32];}chain_proof_t;chain_proof_tjit_signed_compile(constchar*src,size_tn){chain_proof_tp;sm3_hash((uint8_t*)src,n,p.src_h);zend_op_array*oacompile_string(src,n);sm3_hash((uint8_t*)oa-opcodes,oa-last*sizeof(zend_op),p.op_h);uint8_t*mcjit_compile(oa);size_tmclenjit_size(oa);uint8_t*encmalloc(mclen);sm4_crypt_ecb(rk_enc,1,mclen,mc,enc);sm3_hash(enc,mclen,p.mc_h);/* 三段哈希拼一起再签部署时校验 */returnp;}6.PCIe直通HSM密钥隔离 大白话密钥永不出 HSM 卡。PHP 通过 mmap PCIe BAR 寄存器把待加密数据丢进去HSM 算完结果回写到指定地址。#defineHSM_BAR/dev/uio0#defineREG_OP0x00#defineREG_IN0x08#defineREG_OUT0x108volatileuint8_t*hsm;voidhsm_init(void){intfdopen(HSM_BAR,O_RDWR|O_SYNC);hsmmmap(0,4096,PROT_READ|PROT_WRITE,MAP_SHARED,fd,0);}inthsm_sm4_encrypt(constuint8_t*in,size_tn,uint8_t*out){memcpy((void*)(hsmREG_IN),in,n);*(volatileuint32_t*)(hsmREG_OP)0x1001;/*

份秘密分享每份给一个参与方单方看不出原值运算时各方一起算。typedefstruct{uint64_tshares[3];}mpc_zval_t;/* 3方

热点函数是就钉到大核上。SEC(cgroup/sched_switch)intsched_pick(structsched_ctx*ctx){__u64 ipctx-next_ip;__u8*hotbpf_map_lookup_elem(hot_funcs,ip);if(hot*hot){ctx-cpu_mask0xF0;/* 鲲鹏高频大核0xF0~0xFF */}return0;}/* 用户态把PHP热点函数地址灌进hot_funcs map */voidmark_hot(uintptr_tfn){__u8 v1;bpf_map_update_elem(map_fd,fn,v,0);}11.UOS Landlock LSM线程级文件视图 大白话Landlock 让你给单个线程画一个它能看到的目录沙盒PHP 协程跑租户代码时只能看自己那块。#includelinux/landlock.hintsandbox_thread(constchar*root){structlandlock_ruleset_attra{.handled_access_fsLANDLOCK_ACCESS_FS_READ_FILE|LANDLOCK_ACCESS_FS_WRITE_FILE};intrssyscall(SYS_landlock_create_ruleset,a,sizeof(a),0);intfdopen(root,O_PATH|O_CLOEXEC);structlandlock_path_beneath_attrp{.allowed_accessa.handled_access_fs,.parent_fdfd};syscall(SYS_landlock_add_rule,rs,LANDLOCK_RULE_PATH_BENEATH,p,0);prctl(PR_SET_NO_NEW_PRIVS,1,0,0,0);returnsyscall(SYS_landlock_restrict_self,rs,0);}12.麒麟RT调度JIT优先级

标签指针高位也带标签越界访问标签不匹配直接异常硬件级防溢出。#includearm_acle.hvoid*mte_alloc(size_tn){void*paligned_alloc(16,n);/* 给这块内存打随机标签 */void*tagged__arm_mte_create_random_tag(p,0);__arm_mte_set_tag(tagged);/* 内存区也染同色
