2017-12-20block: unalign call_single_data in struct requestJens Axboe
A previous change blindly added massive alignment to the call_single_data structure in struct request. This ballooned it in size from 296 to 320 bytes on my setup, for no valid reason at all. Use the unaligned struct __call_single_data variant instead.

2017-12-20ipv4: Fix use-after-free when flushing FIB tablesIdo Schimmel
Since commit 0ddcf43d5d4a ("ipv4: FIB Local/MAIN table collapse") the local table uses the same trie allocated for the main table when custom rules are not in use. When a net namespace is dismantled, the main table is flushed and freed (via an RCU callback) before the local table. In case the callback is invoked before the local table is iterated, a use-after-free can occur. Fix this by iterating over the FIB tables in reverse order, so that the main table is always freed after the local table. v3: Reworded comment according to Alex's suggestion. v2: Add a comment to make the fix more explicit per Dave's and Alex's feedback.

2017-12-20tipc: remove joining group member from congested listJon Maloy
When we receive a JOIN message from a peer member, the message may contain an advertised window value ADV_IDLE that permits removing the member in question from the tipc_group::congested list. However, since the removal has been made conditional on that the advertised window is *not* ADV_IDLE, we miss this case. This has the effect that a sender sometimes may enter a state of permanent, false, broadcast congestion. We fix this by unconditinally removing the member from the congested list before calling tipc_member_update(), which might potentially sort it into the list again.

Commit f5775e0b6116 ("x86/xen: discard RAM regions above the maximum reservation") left host memory not assigned to dom0 as available for memory hotplug. Unfortunately this also meant that those regions could be used by others. Specifically, commit fa564ad96366 ("x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f, 60-7f)") may try to map those addresses as MMIO.

2017-12-20block-throttle: avoid double chargeShaohua Li
If a bio is throttled and split after throttling, the bio could be resubmited and enters the throttling again. This will cause part of the bio to be charged multiple times. If the cgroup has an IO limit, the double charge will significantly harm the performance. The bio split becomes quite common after arbitrary bio size change. To fix this, we always set the BIO_THROTTLED flag if a bio is throttled. If the bio is cloned/split, we copy the flag to new bio too to avoid a double charge. However, cloned bio could be directed to a new disk, keeping the flag be a problem. The observation is we always set new disk for the bio in this case, so we can clear the flag in bio_set_dev(). This issue exists for a long time, arbitrary bio size change just makes it worse, so this should go into stable at least since v4.2.

There could be multiple entities trying to offload the same filter. Throw out all the tracking and corresponding commands and simply pass to the drivers both old and new bpf program.

2017-12-20net: Fix double free and memory corruption in get_net_ns_by_id()Eric W. Biederman
(I can trivially verify that that idr_remove in cleanup_net happens after the network namespace count has dropped to zero --EWB) Function get_net_ns_by_id() does not check for net::count after it has found a peer in netns_ids idr. It may dereference a peer, after its count has already been finaly decremented. This leads to double free and memory corruption: put_net(peer) rtnl_lock() atomic_dec_and_test(&peer->count) [count=0] ... __put_net(peer) get_net_ns_by_id(net, id) spin_lock(&cleanup_list_lock) list_add(&net->cleanup_list, &cleanup_list) spin_unlock(&cleanup_list_lock) queue_work() peer = idr_find(&net->netns_ids, id) | get_net(peer) [count=1] | ... | (use after final put) v ... cleanup_net() ... spin_lock(&cleanup_list_lock) ... list_replace_init(&cleanup_list, ..) ... spin_unlock(&cleanup_list_lock) ... ... ... ... put_net(peer) ... atomic_dec_and_test(&peer->count) [count=0] ... spin_lock(&cleanup_list_lock) ... list_add(&net->cleanup_list, &cleanup_list) ... spin_unlock(&cleanup_list_lock) ... queue_work() ... rtnl_unlock() rtnl_lock() ... for_each_net(tmp) { ... id = __peernet2id(tmp, peer) ... spin_lock_irq(&tmp->nsid_lock) ... idr_remove(&tmp->netns_ids, id) ... ... ... net_drop_ns() ... net_free(peer) ... } ... | v cleanup_net() ... (Second free of peer) Also, put_net() on the right cpu may reorder with left's cpu list_replace_init(&cleanup_list, ..), and then cleanup_list will be corrupted. Since cleanup_net() is executed in worker thread, while put_net(peer) can happen everywhere, there should be enough time for concurrent get_net_ns_by_id() to pick the peer up, and the race does not seem to be unlikely. The patch fixes the problem in standard way. (Also, there is possible problem in peernet2id_alloc(), which requires check for net::count under nsid_lock and maybe_get_net(peer), but in current stable kernel it's used under rtnl_lock() and it has to be safe. Openswitch begun to use peernet2id_alloc(), and possibly it should be fixed too. While this is not in stable kernel yet, so I'll send a separate message to netdev@ later).
