iproute2: fix build failure on ppc64le
|
||
|
||
ppc64le build fails with error on ifstat.c when
|
||
-Wincompatible-pointer-types is enabled:
|
||
|
||
ifstat.c: In function ‘dump_raw_db’:
|
||
ifstat.c:323:44: error: initialization of ‘long long unsigned int *’ from incompatible pointer type ‘__u64 *’ {aka ‘long unsigned int *’} [-Wincompatible-pointer-types]
|
||
323 | unsigned long long *vals = n->val;
|
||
|
||
Several other warnings are produced when -Wformat= is set, for example:
|
||
|
||
ss.c:3244:34: warning: format ‘%llu’ expects argument of type ‘long long unsigned int’, but argument 2 has type ‘__u64’ {aka ‘long unsigned int’} [-Wformat=]
|
||
3244 | out(" rcv_nxt:%llu", s->mptcpi_rcv_nxt);
|
||
| ~~~^ ~~~~~~~~~~~~~~~~~
|
||
| | |
|
||
| | __u64 {aka long unsigned int}
|
||
| long long unsigned int
|
||
| %lu
|
||
|
||
This happens because __u64 is defined as long unsigned on ppc64le. As
|
||
pointed out by Florian Weimar, we should use -D__SANE_USERSPACE_TYPES__
|
||
if we really want to use long long unsigned in iproute2.
|
||
|
||
This fix the build failure and all the warnings without any change on
|
||
the code itself.
