* hlist: drop the node parameter from iteratorsSasha Levin2013-02-2811-149/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * batman-adv: Fix NULL pointer dereference in DAT hash collision avoidancePau Koning2013-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | An entry in DAT with the hashed position of 0 can cause a NULL pointer dereference when the first entry is checked by batadv_choose_next_candidate. This first candidate automatically has the max value of 0 and the max_orig_node of NULL. Not checking max_orig_node for NULL in batadv_is_orig_node_eligible will lead to a NULL pointer dereference when checking for the lowest address. This problem was added in 785ea1144182c341b8b85b0f8180291839d176a8 ("batman-adv: Distributed ARP Table - create DHT helper functions").

| | | | | | | | | | | | | | | | All packet headers in front of an ethernet header have to be completely divisible by 2 but not by 4 to make the payload after the ethernet header again 4 bytes boundary aligned. A packing of 2 is necessary to avoid extra padding at the end of the struct caused by a structure member which is larger than two bytes. Otherwise the structure would not fulfill the previously mentioned rule to avoid the misalignment of the payload after the ethernet header. It may also lead to leakage of information when the padding it not initialized before sending.

* batman-adv: Add wrapper to look up neighbor and send skbMartin Hundebøll2012-11-216-107/+74
| | | | | | | | | | | | | | | | | | | By adding batadv_send_skb_to_orig() in send.c, we can remove duplicate code that looks up the next hop and then calls batadv_send_skb_packet(). Furthermore, this prepares the upcoming new implementation of fragmentation, which requires the next hop to route packets. Please note that this doesn't entirely remove the next-hop lookup in routing.c and unicast.c, since it is used by the current fragmentation code. Also note that the next-hop info is removed from debug messages in translation-table.c, since it is looked up elsewhere.

* batman-adv: support array of debugfs general attributesAntonio Quartulli2012-11-211-9/+25
| | | | | | | | | | | | This patch adds support for an array of debugfs general (not soft_iface specific) attributes. With this change it will be possible to add more general attributes by simply appending them to the array without touching the rest of the code.

* batman-adv: Mark best gateway in transtable_global debugfsSven Eckelmann2012-11-211-26/+64
| | | | | | | | | | | | | | The transtable_global debug file can show multiple entries for a single client when multiple gateways exist. The chosen gateway isn't marked in the list and therefore the user cannot easily debug the situation when there is a problem with the currently used gateway. The best gateway is now marked with "*" and secondary gateways are marked with "+".
