uclibc-ng 1.0.40 - prlimit issues - devel

4 Feb 2022

I'm having an issue with the new 'prlimit' additions to 1.0.40. One of 
my targets runs an older kernel that predates the prlimit64 syscall.  I 
sent in patch that guards around that code, though it would still be 
defined in headers and probably still cause me issues.

My other target uses kernel 2.6.36.4, which should include the syscall, 
but I get an error the same as this github issue.
https://github.com/util-linux/util-linux/commit/01e94325e676f36b364032a6f5a…

Also, when I try to compile sample program that target:
#include <sys/types.h>
#include <sys/time.h>
#include <sys/resource.h>
#include <stddef.h>

int main ()
{

     int ret;
     ret = prlimit(0, RLIMIT_AS, NULL, NULL);
     if (ret != 0) {
         return 1;
     };

return 0;
}

I get error
prlimit.c:10:11: warning: implicit declaration of function ‘prlimit’; 
did you mean ‘setrlimit’? [-Wimplicit-function-declaration]
    10 |     ret = prlimit(0, RLIMIT_AS, NULL, NULL);
       |                  ^~~~~~~
       |                 setrlimit

on unpatched uclibc-ng like symbols still aren't being visible.

thanks,
