07f6155 Serhey Popovych 20 June 2017, 10:29:25 UTC ipv6: Do not leak throw route references While commit 73ba57bfae4a ("ipv6: fix backtracking for throw routes") does good job on error propagation to the fib_rules_lookup() in fib rules core framework that also corrects throw routes handling, it does not solve route reference leakage problem happened when we return -EAGAIN to the fib_rules_lookup() and leave routing table entry referenced in arg->result. If rule with matched throw route isn't last matched in the list we overwrite arg->result losing reference on throw route stored previously forever. We also partially revert commit ab997ad40839 ("ipv6: fix the incorrect return value of throw route") since we never return routing table entry with dst.error == -EAGAIN when CONFIG_IPV6_MULTIPLE_TABLES is on. Also there is no point to check for RTF_REJECT flag since it is always set throw route.

dec6b33 Raju Rangoju 19 June 2017, 14:16:00 UTC cxgb4: notify uP to route ctrlq compl to rdma rspq During the module initialisation there is a possible race (basically race between uld and lld) where neither the uld nor lld notifies the uP about where to route the ctrl queue completions. LLD skips notifying uP as the rdma queues were not created by then (will leave it to ULD to notify the uP). As the ULD comes up, it also skips notifying the uP as the flag FULL_INIT_DONE is not set yet (ULD assumes that the interface is not up yet). Consequently, this race between uld and lld leaves uP unnotified about where to send the ctrl queue completions to, leading to iwarp RI_RES WR failure. Here is the race: CPU 0 CPU1 - allocates nic rx queus - t4_sge_alloc_ctrl_txq() (if rdma rsp queues exists, tell uP to route ctrl queue compl to rdma rspq) - acquires the mutex_lock - allocates rdma response queues - if FULL_INIT_DONE set, tell uP to route ctrl queue compl to rdma rspq - relinquishes mutex_lock - acquires the mutex_lock - enable_rx() - set FULL_INIT_DONE - relinquishes mutex_lock This patch fixes the above issue.

76371d2 Wei Wang 16 June 2017, 17:46:37 UTC decnet: always not take dst->__refcnt when inserting dst into hash table In the existing dn_route.c code, dn_route_output_slow() takes dst->__refcnt before calling dn_insert_route() while dn_route_input_slow() does not take dst->__refcnt before calling dn_insert_route(). This makes the whole routing code very buggy. In dn_dst_check_expire(), dnrt_free() is called when rt expires. This makes the routes inserted by dn_route_output_slow() not able to be freed as the refcnt is not released. In dn_dst_gc(), dnrt_drop() is called to release rt which could potentially cause the dst->__refcnt to be dropped to -1. In dn_run_flush(), dst_free() is called to release all the dst. Again, it makes the dst inserted by dn_route_output_slow() not able to be released and also, it does not wait on the rcu and could potentially cause crash in the path where other users still refer to this dst. This patch makes sure both input and output path do not take dst->__refcnt before calling dn_insert_route() and also makes sure dnrt_free()/dst_free() is called when removing dst from the hash table. The only difference between those 2 calls is that dnrt_free() waits on the rcu while dst_free() does not.

988c732 Xin Long 15 June 2017, 09:49:08 UTC sctp: return next obj by passing pos + 1 into sctp_transport_get_idx In sctp_for_each_transport, pos is used to save how many objs it has dumped. Now it gets the last obj by sctp_transport_get_idx, then gets the next obj by sctp_transport_get_next. The issue is that in the meanwhile if some objs in transport hashtable are removed and the objs nums are less than pos, sctp_transport_get_idx would return NULL and hti.walker.tbl is NULL as well. At this moment it should stop hti, instead of continue getting the next obj. Or it would cause a NULL pointer dereference in sctp_transport_get_next. This patch is to pass pos + 1 into sctp_transport_get_idx to get the next obj directly, even if pos > objs nums, it would return NULL and stop hti.

5f2f976 David Howells 14 June 2017, 23:12:24 UTC rxrpc: Fix several cases where a padded len isn't checked in ticket decode This fixes CVE-2017-7482. When a kerberos 5 ticket is being decoded so that it can be loaded into an rxrpc-type key, there are several places in which the length of a variable-length field is checked to make sure that it's not going to overrun the available data - but the data is padded to the nearest four-byte boundary and the code doesn't check for this extra. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. Fix this by making the various variable-length data checks use the padded length.

f8a894b Xin Long 15 June 2017, 08:33:58 UTC ipv6: fix calling in6_ifa_hold incorrectly for dad work Now when starting the dad work in addrconf_mod_dad_work, if the dad work is idle and queued, it needs to hold ifa. The problem is there's one gap in [1], during which if the pending dad work is removed elsewhere. It will miss to hold ifa, but the dad word is still idea and queue. if (!delayed_work_pending(&ifp->dad_work)) in6_ifa_hold(ifp); <--------------[1] mod_delayed_work(addrconf_wq, &ifp->dad_work, delay); An use-after-free issue can be caused by this. Chen Wei found this issue when WARN_ON(!hlist_unhashed(&ifp->addr_lst)) in net6_ifa_finish_destroy was hit because of it. As Hannes' suggestion, this patch is to fix it by holding ifa first in addrconf_mod_dad_work, then calling mod_delayed_work and putting ifa if the dad_work is already in queue. Note that this patch did not choose to fix it with: if (!mod_delayed_work(delay)) in6_ifa_hold(ifp); As with it, when delay == 0, dad_work would be scheduled immediately, all addrconf_mod_dad_work(0) callings had to be moved under ifp->lock.

849a44d Jesper Dangaard Brouer 14 June 2017, 11:27:37 UTC net: don't global ICMP rate limit packets originating from loopback Florian Weimer seems to have a glibc test-case which requires that loopback interfaces does not get ICMP ratelimited. This was broken by commit c0303efeab73 ("net: reduce cycles spend on ICMP replies that gets rate limited"). An ICMP response will usually be routed back-out the same incoming interface. Thus, take advantage of this and skip global ICMP ratelimit when the incoming device is loopback. In the unlikely event that the outgoing it not loopback, due to strange routing policy rules, ICMP rate limiting still works via peer ratelimiting via icmpv4_xrlim_allow(). Thus, we should still comply with RFC1812 (section 4.3.2.8 "Rate Limiting"). This seems to fix the reproducer given by Florian. While still avoiding to perform expensive and unneeded outgoing route lookup for rate limited packets (in the non-loopback case).

0ca4cd7 Jiri Kosina 09 June 2017, 11:15:37 UTC HID: let generic driver yield control iff specific driver has been enabled There are many situations where generic HID driver provides some basic level of support for certain device, but later this support (usually by implementing vendor-specific extensions of HID protocol) is extended and the support moved over to a separate (usually per-vendor) specific driver. This might bring a rather unpleasant suprise for users, as all of a sudden there is a new config option they have to enable in order to get any support for their device whatsoever, although previous kernel versions provided basic support through the generic driver. Which is rightfully seen as a regression. Fix this by including the entry for a particular device in hid_have_special_driver[] iff the specific config option has been specified, and let generic driver handle the device otherwise. Also make the behavior of hid_scan_report() (where the same decision is being taken on a per-report level) consistent. While at it, reshuffle the hid_have_special_driver[] a bit to restore the alphabetical ordering (first order by config option, and within those sections order by VID). This is considered a short-term solution, before generic way of giving precedence to special drivers and falling back to generic driver is figured out. While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for spotting this (and for discovering a few issues in the conversion).

b3dd827 Emmanuel Grumbach 10 June 2017, 10:52:45 UTC mac80211: don't send SMPS action frame in AP mode when not needed mac80211 allows to modify the SMPS state of an AP both, when it is started, and after it has been started. Such a change will trigger an action frame to all the peers that are currently connected, and will be remembered so that new peers will get notified as soon as they connect (since the SMPS setting in the beacon may not be the right one). This means that we need to remember the SMPS state currently requested as well as the SMPS state that was configured initially (and advertised in the beacon). The former is bss->req_smps and the latter is sdata->smps_mode. Initially, the AP interface could only be started with SMPS_OFF, which means that sdata->smps_mode was SMPS_OFF always. Later, a nl80211 API was added to be able to start an AP with a different AP mode. That code forgot to update bss->req_smps and because of that, if the AP interface was started with SMPS_DYNAMIC, we had: sdata->smps_mode = SMPS_DYNAMIC bss->req_smps = SMPS_OFF That configuration made mac80211 think it needs to fire off an action frame to any new station connecting to the AP in order to let it know that the actual SMPS configuration is SMPS_OFF. Fix that by properly setting bss->req_smps in ieee80211_start_ap.

The driver may, like iwlwifi does, access more data from bss_info in that case and iwlwifi accesses the basic_rates bitmap, but if changing from a band with more (basic) rates to one with fewer, an out-of-bounds access of the rate array may result. While we can't avoid having invalid data at some point in time, we can avoid having it while we call the driver - so set up all the data before configuring the channel, and then apply it afterwards.

6964e53 Jacob Keller 12 June 2017, 22:38:36 UTC i40e: fix handling of HW ATR eviction A recent commit to refactor the driver and remove the hw_disabled_flags field accidentally introduced two regressions. First, we overwrote pf->flags which removed various key flags including the MSI-X settings. Additionally, it was intended that we have now two flags, HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done, and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere. This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely updates pf->flags instead of overwriting it. Without this patch we will have many problems including disabling MSI-X support, and we'll attempt to use HW ATR eviction on devices which do not support it.

83848fb Lv Zheng 07 June 2017, 04:54:58 UTC ACPICA: Tables: Mechanism to handle late stage acpi_get_table() imbalance Considering this case: 1. A program opens a sysfs table file 65535 times, it can increase validation_count and first increment cause the table to be mapped: validation_count = 65535 2. AML execution causes "Load" to be executed on the same table, this time it cannot increase validation_count, so validation_count remains: validation_count = 65535 3. The program closes sysfs table file 65535 times, it can decrease validation_count and the last decrement cause the table to be unmapped: validation_count = 0 4. AML code still accessing the loaded table, kernel crash can be observed. To prevent that from happening, add a validation_count threashold. When it is reached, the validation_count can no longer be incremented/decremented to invalidate the table descriptor (means preventing table unmappings) Note that code added in acpi_tb_put_table() is actually a no-op but changes the warning message into a "warn once" one.

4b1f0d3 Donald Sharp 10 June 2017, 20:30:17 UTC net: ipmr: Fix some mroute forwarding issues in vrf's This patch fixes two issues: 1) When forwarding on *,G mroutes that are in a vrf, the kernel was dropping information about the actual incoming interface when calling ip_mr_forward from ip_mr_input. This caused ip_mr_forward to send the multicast packet back out the incoming interface. Fix this by modifying ip_mr_forward to be handed the correctly resolved dev. 2) When a unresolved cache entry is created we store the incoming skb on the unresolved cache entry and upon mroute resolution from the user space daemon, we attempt to forward the packet. Again we were not resolving to the correct incoming device for a vrf scenario, before calling ip_mr_forward. Fix this by resolving to the correct interface and calling ip_mr_forward with the result.

661d2b0 Netanel Belgazal 11 June 2017, 12:42:46 UTC net: ena: fix race condition between submit and completion admin command Bug: "Completion context is occupied" error printout will be noticed in dmesg. This error will cause the admin command to fail, which will lead to an ena_probe() failure or a watchdog reset (depends on which admin command failed). Root cause: __ena_com_submit_admin_cmd() is the function that submits new entries to the admin queue. The function have a check that makes sure the queue is not full and the function does not override any outstanding command. It uses head and tail indexes for this check. The head is increased by ena_com_handle_admin_completion() which runs from interrupt context, and the tail index is increased by the submit function (the function is running under ->q_lock, so there is no risk of multithread increment). Each command is associated with a completion context. This context allocated before call to __ena_com_submit_admin_cmd() and freed by ena_com_wait_and_process_admin_cq_interrupts(), right after the command was completed. This can lead to a state where the head was increased, the check passed, but the completion context is still in use. Solution: Use the atomic variable ->outstanding_cmds instead of using the head and the tail indexes. This variable is safe for use since it is bumped in get_comp_ctx() in __ena_com_submit_admin_cmd() and is freed by comp_ctxt_release() Fixes: 1738cd3ed342 ("Add a driver for Amazon Elastic Network Adapters (ENA)") Signed-off-by: Netanel Belgazal <netanel@amazon.com> Signed-off-by: David S.
