IP_VS kernel modules missing - enablement request on raspberrypi / linux #265

So, is the request for |
|
Yes CONFIG_IP_VS and all IP_VS Subfeatgers. it Compiles well on 3.8.4 docu : My LB ´s Simple Setup:
crm configure primitive MAILIP ocf:heartbeat:IPaddr2 params ip="192.168.1.31" nic="eth0" \
op monitor interval="10s" meta is-managed="true"
crm configure primitive SQLIP ocf:heartbeat:IPaddr2 params ip="192.168.1.42" nic="eth0" \
op monitor interval="10s" meta is-managed="true"
crm configure primitive WEBIP ocf:heartbeat:IPaddr2 params ip="192.168.1.40" nic="eth0" \
op monitor interval="10s" mea is-managed="true"
crm configure primitive ldirectord ocf:heartbeat:ldirectord params configfile="/etc/ha.d/ldirectord.cf" \
op monitor interval="2m" timeout="20s" op start interval="0" timeout="90s" \
op stop interval="0" timeout="100s" meta target-role="Started"
You may need to create an Group at least ONE IP and the ldirectord together to get the Failover to work.
crm configure group LVS WEBIP ldirectord meta target-role="Started"
The Load Balancing been then managed by the ldirectord same way as the HeartBeat v2 samples on the Internet.

Thanks for enable IP_VS and ARPD at 3.8.8 kernel dmesg | grep IPVS |

commit 0048b48 upstream. Inside timeout handler, blk_mq_tag_to_rq() is called to retrieve the request from one tag. This way is obviously wrong because the request can be freed any time and some fiedds of the request can't be trusted, then kernel oops might be triggered[1]. Currently wrt. blk_mq_tag_to_rq(), the only special case is that the flush request can share same tag with the request cloned from, and the two requests can't be active at the same time, so this patch fixes the above issue by updating tags->rqs[tag] with the active request(either flush rq or the request cloned from) of the tag. Also blk_mq_tag_to_rq() gets much simplified with this patch. Given blk_mq_tag_to_rq() is mainly for drivers and the caller must make sure the request can't be freed, so in bt_for_each() this helper is replaced with tags->rqs[tag].

commit f39ea26 upstream. Use kzalloc instead of kmalloc for struct tid_ampdu_rx to initialize the "removed" field (all others are initialized manually). That fixes: UBSAN: Undefined behaviour in net/mac80211/rx.c:932:29 load of value 2 is not a valid value for type '_Bool' CPU: 3 PID: 1134 Comm: kworker/u16:7 Not tainted 4.5.0-rc1+ #265 Workqueue: phy0 rt2x00usb_work_rxdone 0000000000000004 ffff880254a7ba50 ffffffff8181d866 0000000000000007 ffff880254a7ba78 ffff880254a7ba68 ffffffff8188422d ffffffff8379b500 ffff880254a7bab8 ffffffff81884747 0000000000000202 0000000348620032 Call Trace: [<ffffffff8181d866>] dump_stack+0x45/0x5f [<ffffffff8188422d>] ubsan_epilogue+0xd/0x40 [<ffffffff81884747>] __ubsan_handle_load_invalid_value+0x67/0x70 [<ffffffff82227b4d>] ieee80211_sta_reorder_release.isra.16+0x5ed/0x730 [<ffffffff8222ca14>] ieee80211_prepare_and_rx_handle+0xd04/0x1c00 [<ffffffff8222db03>] __ieee80211_rx_handle_packet+0x1f3/0x750 [<ffffffff8222e4a7>] ieee80211_rx_napi+0x447/0x990 While at it, convert to use sizeof(*tid_agg_rx) instead.

syzbot reported one use-after-free in pfifo_fast_enqueue() [1] Issue here is that we can not reuse skb after a successful skb_array_produce() since another cpu might have consumed it already. I believe a similar problem exists in try_bulk_dequeue_skb_slow() in case we put an skb into qdisc_enqueue_skb_bad_txq() for lockless qdisc.

Add a new test case which performs double query of the bpf_mprog through libbpf API, but also via raw bpf(2) syscall.
