[Buildroot] [RFC PATCH v2 0/3] Fix old toolchain (< v3.14)

[Petr Vorel]

Hi,

NOTE: this fix (3rd commit) is needed obviously due very old toolchain
(sourcery-arm from Buildroot). I suppose it's still used, but can
anybody from Buildroot confirm this?

Kind regards,
Petr

changes v1->v2:
* fixing moving IFA_FLAGS from lapi/rtnetlink.h to lapi/if_addr.h
  (it was by accident done in 2 commits)
* new commit tst_netdevice.c: Drop redundant include

Petr Vorel (3):
  tst_netdevice.c: Drop redundant include
  lapi: Create if_addr.h and reuse it in rtnetlink.h
  lapi/if_addr.h: Define IFA_FLAGS

I suppose that you have tested this in CI and that it works fine. If
that is so:

[Buildroot] [RFC PATCH v2 2/3] lapi: Create if_addr.h and reuse it in rtnetlink.h

[Petr Vorel]

There will be fix in next commit for missing IFA_F_NOPREFIXROUTE which
requires creating lapi/if_addr.h. Thus move IFA_FLAGS to lapi/if_addr.h,
as it belongs there and reuse lapi/if_addr.h in lapi/rtnetlink.h just
like <linux/rtnetlink.h> includes <linux/if_addr.h>.

[Buildroot] [RFC PATCH v2 3/3] lapi/if_addr.h: Define IFA_FLAGS

[Petr Vorel]

and use it in icmp_rate_limit01.c.

This fixes error on toolchains with very old kernel headers, e.g.
Buildroot sourcery-arm:

icmp_rate_limit01.c:82:3: error: 'IFA_F_NOPREFIXROUTE' undeclared (first use in this function)
   IFA_F_NOPREFIXROUTE);

Fixed because IFA_F_NOPREFIXROUTE was added in 3.14 and the oldest
system we still support is Cent0S 7 with 3.10 kernel.

NOTE: Cent0S 7 is obviously heavily patched thus it contains
IFA_F_NOPREFIXROUTE and therefore CI build didn't catch this error.

Hi,
commit message for this patch should be "Define IFA_F_NOPREFIXROUTE" but
that can be fixed during merge. Apart from that, the whole patchset
looks good.
