            Bug ID: 29622
           Summary: Open file permission error under aarch64 architecture
           Product: glibc
           Version: 2.28
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: dluyaning at gmail dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

strace log:

openat(AT_FDCWD, "/home/lyn/test/", O_RDWR|O_CLOEXEC|O_TMPFILE, 0134240) = 12
write(12, "11111\0", 6) = 6
lseek(12, 0, SEEK_SET) = 0

demo:
#define _GNU_SOURCE

#include <unistd.h>
#include <stdlib.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <linux/limits.h>
#include <errno.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>

int main()
{
char path[PATH_MAX];
int fd = open("/home/lyn/test", O_TMPFILE | O_RDWR, S_IRUSR | S_IWUSR);
write(fd, "hello", 5);
fsync(fd);
printf("pidis %d\n", getpid());
snprintf(path, PATH_MAX, "/proc/self/fd/%d", fd);
int ret = linkat(fd, path, AT_FDCWD, "yyyy", AT_SYMLINK_FOLLOW);
if(ret < 0)

{ printf("linkat error %d %s\n", errno, strerror(errno)); }
pause();

return 0;
}

2.28 is no longer supported and I cannot reproduce that with 2.36.

> 2.28 不再受支持,我无法用 2.36 重现它。

__libc_openat64 There seems to be no change from 2.28 to 2.36. Can you provide
a debugging method for debugging glibc 2.36?
