chenjing e50cf0be6f feat: fatfs支持符号链接功能
1 将fatfs_creat与fatfs_mkdir抽象成fatfs_creat_obj,通过参数type控制创建的对象类型;
2 新增fatfs_symlink与fatfs_readlink接口,其中:
   1) fatfs_symlink通过fatfs_creat_obj创建出符号链接文件,并为其申请新簇,将target内容写入簇的第一个sector;
   2) fatfs_readlink读出符号链接文件对应簇中第一个sector的内容

chenjing 6eddc869d3 feat: support link/symlink/readlink
新增link/symlink/readlink接口的系统调用及内核实现,当前仅支持jffs2文件系统。具体接口说明如下:

一、hard link
接口原型:
int link(const char *oldpath, const char *newpath);
int linkat(int olddirfd, const char *oldpath, int newdirfd, const char *newpath, int flags);

作用:
创建oldpath的硬链接,名为newpath。

功能说明:
1、newpath与oldpath必须在同一挂载分区内。
2、若newpath已存在,不会覆盖,错误码EEXIST。
3、oldpath必须为普通文件或者软链接文件。
4、如果oldpath是一个软链接文件,那么:
若调用link接口或者linkat(flags=0),创建出软链接文件的硬链接;
若调用linkat(flags = AT_SYMLINK_FOLLOW),创建出软链接所指向源文件的硬链接。
5、oldpath与newpath对应同一个文件,对oldpath与newpath任一名字的操作都是直接操作文件,没有“原始文件”的说法。
6、使用cp命令拷贝一个硬链接文件,生成文件的拷贝,新文件的nlink数为1。
7、删除oldpath或newpath,底层文件仍存在,可以通过另一个path访问。只有当两个path都删除之后,才会真正将文件删除,空间释放。

二、symbol link
接口原型:
int symlink(const char *target, const char *linkpath);
int symlinkat(const char *target, int newdirfd, const char *linkpath);

作用:
创建一个软链接文件linkpath,存储字符串target。

功能说明:
1、target可以为任意字符串(长度小于PATH_MAX)。
2、若linkpath文件名已存在,不会覆盖,错误码EEXIST。
3、用readlink函数可读取软链接的target内容。
4、软链接文件本身大小为target长度。
5、ls时软链接文件类型显示为 'l'。
6、symlink最大循环次数为CONFIG_FS_MAX_LNK_CNT(目前为40),超出则返回错误,错误码ELOOP。
7、使用cp命令拷贝一个软链接文件:
若target是一个文件:创建一个源文件的拷贝,类型为普通文件;
若target非文件:拷贝失败。

三、readlink
接口原型:
ssize_t readlink(const char *pathname, char *buf, size_t bufsiz);
ssize_t readlinkat(int dirfd, const char *pathname, char *buf, size_t bufsiz);

作用:
读取软链接文件存放的的target内容。

功能说明:
1、pathname必须为软链接文件,否则错误码EINVAL。
2、如果bufsiz小于target长度,则截断target。

Guangyao Ma 565b2e85cd refactor(mksh): reduce the mksh size by Oz
clang不支持“-flto,-Oz”作为链接选项,但是可以作为编译选项,且作为编译选项时,有更好的size减少效果。这里为了使用这种
编译选项组合,且为了不影响链接过程(Build.sh链接时也会使用CFLAGS),在链接选项生效的-O选项中,重置其为O2。
最终size可以从300+k,缩减为不到180k。

YOUR_NAME 44ce696904 fix: 内核态在console初始化完成后,使用printf无法正常打印
printf实现流程上会调用cmd为TIOCGWINSZ的ioctl命令,该命令的实现
在console层ConsoleGetWinSize函数中,而此函数copy结果时使用函数
LOS_ArchCopyToUser,由于该过程在内核态,导致LOS_ArchCopyToUser失败,
从而引发printf无法正常打印的问题。

Kiita 09756fe55b refactor: 对toybox侵入式修改进行分离
【背景】当前liteos_a支持的toybox命令与linux存在差别,需要特别实现,为
避免侵入式修改,采用porting的方式将修改分离。

【修改方案】
在third_party/toybox下新增porting目录,以达到分离修改的目的。本次修改
基于porting目录且只涉及liteos目前支持的命令文件。

lnlan 0676578aae fix(kernel_test): 内核mem/shm冒烟用例重复运行失败
【背景】内核mem/shm冒烟用例概率性失败门禁中shm冒烟用例失败,经验证
与构建,不符合预期

【修改方案】
原内核用例的源文件是通过框架自带的source_set(一种虚拟静态库)的方式组织的,
不受unittests(自定义的一种方式)控制,修改为文件列表直接加入到unittest中。

【影响】
对现有的产品编译不会有影响。

chenwei c4595d2504 feat(file system): add memory-based romfs
1, this RomFS's codebase is Nuttx romfs, then it is compatible with
Linux RomFS and you can create such a file system using the tool genromfs.
2, there are two major changes against with the original Nuttx romfs:
    1), it is memory-based: all contents of the fs are stored in the
        memory in the very first stage of "mount".
    2), this version of romfs is altered to be compatible with our new
        version of VFS to take advantage of vnode cache and path cache.
