Hi All,
I try to build rpm for ovs+dpdk, but met below compiling issue. Does someone
know how to fix it? I guess it is related to LDFLAGS='-Wl,-z,relro
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld, but no idea how to fix it.
If I follow below guide (non-rpm), everything is OK.
... yes ". Note that previously I did
not install the glibc-static, standalone ./configure still can succeed though
reports "static ...no".
So question:
why the rpmbuild cannot correct detect the -static flag for gcc?

Ovs and kernel stack would add frag_queue to same netns_frags list.
As result, ovs and kernel may access the fraq_queue without correct
lock. Also the struct ipq may be different on kernel(older than 4.3),
which leads to invalid pointer access.
The fix creates specific netns_frags for ovs.
