Is if_nameindex() supported when combining linux ver5.5 and newlib?

Sourceware - newlib list mailing list

Hi,

Please tell us about the support status of Linux ver5.5.

Is if_nameindex() supported when combining linux ver5.5 and newlib?


Starting with Linux ve5.5, system call _sysctl() is no longer supported.

https://www.phoronix.com/scan.php?page=article&item=linux-55-features&num=1

the newlib library uses _sysctl() to implement if_nameindex().

----------------
newlib\libc\sys\linux\net\ifname.c

struct if_nameindex *
if_nameindex()

---

mib[0] = CTL_NET;
mib[1] = PF_ROUTE;
mib[2] = 0; /* protocol */
mib[3] = 0; /* wildcard address family */
mib[4] = 0;
mib[5] = 0; /* no flags */
if (__sysctl(mib, 6, NULL, &needed, NULL, 0) <0) // <- _sysctl() wrapper function
return NULL;

-------------------


If not support, are there any plans to fix this?
For example, changing to procfs(read "/proc/sys").
