Re: [PULL 00/12] linux-user patches

[Stefan Hajnoczi]

The close_range(2) man page says:
close_range() first appeared in Linux 5.9.  Library support was added
in glibc in version 2.34.

The qemu-user GitLab CI jobs are failing. For example, see
https://gitlab.com/qemu-project/qemu/-/jobs/3043629417:

../linux-user/syscall.c:8734:26: error: implicit declaration of
function 'close_range' is invalid in C99
[-Werror,-Wimplicit-function-declaration]
return get_errno(close_range(arg1, arg2, arg3));
                           ^

There is a second issue with this pull request:
../linux-user/syscall.c:357:16: error: ‘pidfd_getfd’ defined but not
used [-Werror=unused-function]
357 | _syscall3(int, pidfd_getfd, int, pidfd, int, targetfd, unsigned
int, flags);
       | ^~~~~~~~~~~
../linux-user/syscall.c:251:13: note: in definition of macro ‘_syscall3’

See https://gitlab.com/qemu-project/qemu/-/jobs/3043629434.
