6.13号的nightly同样全部失败了。an8上没有支持，因此SKIP掉了。请开发同学帮忙分析一下。 如下是an8上的执行日志。 tst_test.c:1065: TINFO: Formatting /dev/loop0 with ext2 opts='' extra opts='' mke2fs 1.45.6 (20-Mar-2020) ../../../../include/lapi/fsmount.h:111: TCONF: syscall(442) __NR_mount_setattr not supported on your arch tst_test.c:1599: TINFO: Testing on ext3 tst_test.c:1065: TINFO: Formatting /dev/loop0 with ext3 opts='' extra opts='' mke2fs 1.45.6 (20-Mar-2020) ../../../../include/lapi/fsmount.h:111: TCONF: syscall(442) __NR_mount_setattr not supported on your arch tst_test.c:1599: TINFO: Testing on ext4 tst_test.c:1065: TINFO: Formatting /dev/loop0 with ext4 opts='' extra opts='' mke2fs 1.45.6 (20-Mar-2020) ../../../../include/lapi/fsmount.h:111: TCONF: syscall(442) __NR_mount_setattr not supported on your arch tst_test.c:1599: TINFO: Testing on xfs tst_test.c:1065: TINFO: Formatting /dev/loop0 with xfs opts='' extra opts='' ../../../../include/lapi/fsmount.h:111: TCONF: syscall(442) __NR_mount_setattr not supported on your arch tst_test.c:1599: TINFO: Testing on vfat tst_test.c:1065: TINFO: Formatting /dev/loop0 with vfat opts='' extra opts='' ../../../../include/lapi/fsmount.h:111: TCONF: syscall(442) __NR_mount_setattr not supported on your arch tst_test.c:1599: TINFO: Testing on tmpfs tst_test.c:1065: TINFO: Skipping mkfs for TMPFS filesystem tst_test.c:1045: TINFO: Limiting tmpfs size to 32MB ../../../../include/lapi/fsmount.h:111: TCONF: syscall(442) __NR_mount_setattr not supported on your arch
2a1867219c7b fs: add mount_setattr() mount_attr是linux 5.12 新增的系统调用，在5.10内核下，应该skip该测试。
具体解释一下为什么a8会skip而a23不会。 ltp在 configure 阶段，会创建一个 conftest.c 文件，编译并判断glibc中是否存在某一系统调用。如果存在，就会设置 HAVE_MOUNT_SETATTR 该宏为 1 。该宏最终控制syscall的测试是否TPASS。 在a23中，该宏为1，configure阶段的log如下： configure:5419: checking for mount_setattr configure:5419: gcc -o conftest -g -O2 conftest.c >&5 configure:5419: $? = 0 configure:5419: result: yes 在a23中，该宏不存在，configure阶段的log如下： configure:5219: checking for mount_setattr configure:5219: gcc -o conftest -g -O2 conftest.c >&5 /tmp/ccRM1gWI.o: In function `main': /root/myltp/ltp/conftest.c:111: undefined reference to `mount_setattr' collect2: error: ld returned 1 exit status configure:5219: $? = 1 报错信息为，在链接阶段找不到mount_setattr函数，该函数应该是由libc提供的。用grep在/usr目录下搜索： [anolis23]# grep -nr "mount_setattr" /usr grep: /usr/lib64/libc.so.6: binary file matches grep: /usr/lib64/libc.a: binary file matches 而a8中不包含该检索结果，问题应该出在libc上。 用ldd -version 查看c库版本， a8为 2.28 ， a23为2.36。 总结一下，建议以后a23测试跳过该case。视业务实际需要，回合mount_setattr这一特性后再开启
