Subject: [musl] faccessat() always return EPERM
Date: Sat, 24 Jul 2021 04:16:25 +0300 [thread overview]
Message-ID: <CAMhVC3ZwQdPK76Nw2QCc787wD=CN4XixJ1J6YbidhPBt5T-v6g@mail.gmail.com> (raw)
Hi,
I'm not sure that it has something to do with musl. But experienced in
a Alpine Linux docker container (ruby:2.6-alpine3.14) on Debian 9 or
10. I can't reproduce it with Alpine Linux 3.13 (container) or Debian
8 (host).
For example, the following program outputs -1:
#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
int main()
{
int r;
r = faccessat(AT_FDCWD, "/", R_OK, AT_EACCESS);
printf("%i", r);
return 0;
}
I believe whatever is passed as the second parameter, it would return -1.
As a result at least irb and bundler doesn't work. Is this some sort
of binary incompatibility with Linux kernel?
Regards,
Yuri
