2014-01-05net: 6lowpan: fix lowpan_header_create non-compression memcpy callDaniel Borkmann
In function lowpan_header_create(), we invoke the following code construct: struct ipv6hdr *hdr; ... hdr = ipv6_hdr(skb); ... if (...) memcpy(hc06_ptr + 1, &hdr->flow_lbl[1], 2); else memcpy(hc06_ptr, &hdr, 4); Where the else path of the condition, that is, non-compression path, calls memcpy() with a pointer to struct ipv6hdr *hdr as source, thus two levels of indirection. This cannot be correct, and likely only one level of pointer was intended as source buffer for memcpy() here.

2013-11-19genetlink: make multicast groups const, prevent abuseJohannes Berg
Register generic netlink multicast groups as an array with the family and give them contiguous group IDs. Then instead of passing the global group ID to the various functions that send messages, pass the ID relative to the family - for most families that's just 0 because the only have one group. This avoids the list_head and ID in each group, adding a new field for the mcast group ID offset to the family. At the same time, this allows us to prevent abusing groups again like the quota and dropmon code did, since we can now check that a family only uses a group it owns.

2013-11-19genetlink: only pass array to genl_register_family_with_ops()Johannes Berg
As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)

2013-11-18inet: prevent leakage of uninitialized memory to user in recv syscallsHannes Frederic Sowa
Only update *addr_len when we actually fill in sockaddr, otherwise we can return uninitialized memory from the stack to the caller in the recvfrom, recvmmsg and recvmsg syscalls. Drop the the (addr_len == NULL) checks because we only get called with a valid addr_len pointer either from sock_common_recvmsg or inet_recvmsg. If a blocking read waits on a socket which is concurrently shut down we now return zero and set msg_msgnamelen to 0.

2013-11-156lowpan: Uncompression of traffic class field was incorrectJukka Rissanen
If priority/traffic class field in IPv6 header is set (seen when using ssh), the uncompression sets the TC and Flow fields incorrectly. Example: This is IPv6 header of a sent packet. Note the priority/TC (=1) in the first byte. 00000000: 61 00 00 00 00 2c 06 40 fe 80 00 00 00 00 00 00 00000010: 02 02 72 ff fe c6 42 10 fe 80 00 00 00 00 00 00 00000020: 02 1e ab ff fe 4c 52 57 This gets compressed like this in the sending side 00000000: 72 31 04 06 02 1e ab ff fe 4c 52 57 ec c2 00 16 00000010: aa 2d fe 92 86 4e be c6 .... In the receiving end, the packet gets uncompressed to this IPv6 header 00000000: 60 06 06 02 00 2a 1e 40 fe 80 00 00 00 00 00 00 00000010: 02 02 72 ff fe c6 42 10 fe 80 00 00 00 00 00 00 00000020: ab ff fe 4c 52 57 ec c2 First four bytes are set incorrectly and we have also lost two bytes from destination address. The fix is to switch the case values in switch statement when checking the TC field. Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com> Signed-off-by: David S.

2013-08-206lowpan: Fix fragmentation with link-local compressed addressesDavid Hauweele
When a new 6lowpan fragment is received, a skbuff is allocated for the reassembled packet. However when a 6lowpan packet compresses link-local addresses based on link-layer addresses, the processing function relies on the skb mac control block to find the related link-layer address. This patch copies the control block from the first fragment into the newly allocated skb to keep a trace of the link-layer addresses in case of a link-local compressed address.

2013-02-27hlist: drop the node parameter from iteratorsSasha Levin
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.
