[IPSEC]: Move common code into xfrm_alloc_spi
This patch moves some common code that conceptually belongs to the xfrm core from af_key/xfrm_user into xfrm_alloc_spi. In particular, the spin lock on the state is now taken inside xfrm_alloc_spi. Previously it also protected the construction of the response PF_KEY/XFRM messages to user-space. This is inconsistent as other identical constructions are not protected by the state lock. This is bad because they in fact should be protected but only in certain spots (so as not to hold the lock for too long which may cause packet drops). The SPI byte order conversion has also been moved. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
