评论 /sync <branch1> <branch2> ... 可将当前 PR 修改同步到其它分支（创建同步 PR）：
a) 如果当前 PR 是 Open 状态，同步操作将延迟到 PR 被合并时执行
b) 如果当前 PR 已经 Merged，将立即执行同步操作
注意：
- /sync 命令可以指定同步到多个分支，仅最后一个 /sync 命令生效
- 如果创建的同步 PR 不正确，可通过向同步 PR 的源分支提交轻量级 PR 完善，或使用 /close 命令关闭

__1. Agent平台信息: opencode v2.2.2
__2. 模型信息: zai-org/GLM-5.2-FP8
__3. Prompt摘要: 使用 openEuler 漏洞回移技能，为 libbpf 回移上游 ELF 符号表 sh_entsize 零值校验修复，完成复现、补丁、spec 修改与验证
参考：openEuler社区《生成式AI工具使用与开源贡献政策》
PR功能描述 / 为什么需要这个合入**:
elf_find_func_offset()用symbols->d_size / sh.sh_entsize计算符号数量，未校验sh_entsize非零。畸形 ELF 的.symtab段将sh_entsize设为 0 时，uprobe/uretprobe 目标符号解析路径触发除零（SIGFPE）。本 PR 回移上游6c8e5e7d981b45619eccd22d895cec3c6afe3418，在除法前拒绝零sh_entsize，新增backport-libbpf-Validate-ELF-symbol-table-entry-size.patch，Release+1。该PR关联的 issue
(格式为fixes #<issue号>, 或者resolves #<issue号>): fixes #52
希望检视人员了解:
本修复为上游对应修复的同步回移，AI 仅辅助编写与验证；已人工逐行核对逻辑，并完成以下验证：
patch -F0零 fuzz，目标文件 blob 与预期一致；.symtab的sh_entsize改为 0 后，修复前 ASan 报FPE（elf_find_func_offset），修复后返回-LIBBPF_ERRNO__FORMAT，不再崩溃。上游提交链接见 issue #52。该缺陷上游未分配 CVE。
