* feat(filesystem): Enhance symlink handling and VFS behavior - Updated tmpfs to require page cache for both regular files and symlinks to ensure proper read/write operations. - Increased the maximum symlink follow count to 40, aligning with Linux 6.6 standards. - Improved symlink handling in VFS to correctly follow symlinks based on path conditions and trailing slashes. - Added validation for conflicting flags in vfs_statx to prevent invalid operations. - Refined syscall implementations for symlink and lstat to adhere to Linux semantics, ensuring correct behavior for symlink creation and path resolution. Signed-off-by: longjin <longjin@DragonOS.org> * fix(vfs): 修正符号链接跟随次数的处理逻辑 - 将 VFS_MAX_FOLLOW_SYMLINK_TIMES 从 40 调整为 41，以保留 0 的禁用语义并实现最多 40 次跟随的 Linux 语义 - 重构路径解析逻辑，明确区分 max_follow_times 为 0（完全禁用跟随）、1（计数耗尽）及 >=2（允许继续跟随）三种情况 - 确保在计数耗尽（max_follow_times == 1）且需要跟随时正确返回 ELOOP 错误 Signed-off-by: longjin <longjin@DragonOS.org> --------- Signed-off-by: longjin <longjin@DragonOS.org> |
