Tapset porting to 2.6.38

[Turgis, Frederic]

Hi,

I recently ran the testsuite on Linaro kernel (2.6.38 on ARM dual core cortex A9) and found 1 issue coming from 2.6.38 kernel changes. I checked this is not in latest snapshot, I don't seem to find it in bug list so here it is in case nobody has already seen it:

- 2.6.38-rc1 has broken tapset/ip.stp by moving inet_daddr parameter in struct sk, commit 68835aba4d9b74e2f94106d13b6a4bddc447c4c8 impacting include/net/inet_sock.h.
This impacts "function __ip_sock_saddr:long (sock:long)"

It is doing this:
- __be32   inet_daddr;
- __be32   inet_rcv_saddr;
+#define inet_daddr  sk.__sk_common.skc_daddr
+#define inet_rcv_saddr  sk.__sk_common.skc_rcv_saddr


As this is not about only dereferencing pointers, I guess reading "inet_daddr" will require some "pure" code so I didn't propose solution (and it may require kread/CATCH_DEREF_FAULT stuff which I am not familiar with although it is documented)


Regards
Fred
