2016-12-17net: ipv6: check route protocol when deleting routesMantas M1-0/+2
The protocol field is checked when deleting IPv4 routes, but ignored for IPv6, which causes problems with routing daemons accidentally deleting externally set routes (observed by multiple bird6 users).

2016-12-17sctp: sctp_transport_lookup_process should rcu_read_unlock when transport is ↵Xin Long1-4/+3
null Prior to this patch, sctp_transport_lookup_process didn't rcu_read_unlock when it failed to find a transport by sctp_addrs_lookup_transport. This patch is to fix it by moving up rcu_read_unlock right before checking transport and also to remove the out path.

2016-12-17sctp: sctp_epaddr_lookup_transport should be protected by rcu_read_lockXin Long1-1/+4
Since commit 7fda702f9315 ("sctp: use new rhlist interface on sctp transport rhashtable"), sctp has changed to use rhlist_lookup to look up transport, but rhlist_lookup doesn't call rcu_read_lock inside, unlike rhashtable_lookup_fast. It is called in sctp_epaddr_lookup_transport and sctp_addrs_lookup_transport. sctp_addrs_lookup_transport is always in the protection of rcu_read_lock(), as __sctp_lookup_association is called in rx path or sctp_lookup_association which are in the protection of rcu_read_lock() already. But sctp_epaddr_lookup_transport is called by sctp_endpoint_lookup_assoc, it doesn't call rcu_read_lock, which may cause "suspicious rcu_dereference_check usage' in __rhashtable_lookup. This patch is to fix it by adding rcu_read_lock in sctp_endpoint_lookup_assoc before calling sctp_epaddr_lookup_transport.

2016-12-17inet: Fix get port to handle zero port number with soreuseport setTom Herbert2-8/+13
A user may call listen with binding an explicit port with the intent that the kernel will assign an available port to the socket. In this case inet_csk_get_port does a port scan. For such sockets, the user may also set soreuseport with the intent a creating more sockets for the port that is selected. The problem is that the initial socket being opened could inadvertently choose an existing and unreleated port number that was already created with soreuseport. This patch adds a boolean parameter to inet_bind_conflict that indicates rather soreuseport is allowed for the check (in addition to sk->sk_reuseport). In calls to inet_bind_conflict from inet_csk_get_port the argument is set to true if an explicit port is being looked up (snum argument is nonzero), and is false if port scan is done.

2016-12-17inet: Don't go into port scan when looking for specific bind portTom Herbert1-1/+1
inet_csk_get_port is called with port number (snum argument) that may be zero or nonzero. If it is zero, then the intent is to find an available ephemeral port number to bind to. If snum is non-zero then the caller is asking to allocate a specific port number. In the latter case we never want to perform the scan in ephemeral port range. It is conceivable that this can happen if the "goto again" in "tb_found:" is done. This patch adds a check that snum is zero before doing the "goto again".

Pull audit updates from Paul Moore: "After the small number of patches for v4.9, we've got a much bigger pile for v4.10. The bulk of these patches involve a rework of the audit backlog queue to enable us to move the netlink multicasting out of the task/thread that generates the audit record and into the kernel thread that emits the record (just like we do for the audit unicast to auditd). While we were playing with the backlog queue(s) we fixed a number of other little problems with the code, and from all the testing so far things look to be in much better shape now. Doing this also allowed us to re-enable disabling IRQs for some netns operations ("netns: avoid disabling irq for netns id"). The remaining patches fix some small problems that are well documented in the commit descriptions, as well as adding session ID filtering support" * 'stable-4.10' of git://git.infradead.org/users/pcmoore/audit: audit: use proper refcount locking on audit_sock netns: avoid disabling irq for netns id audit: don't ever sleep on a command record/message audit: handle a clean auditd shutdown with grace audit: wake up kauditd_thread after auditd registers audit: rework audit_log_start() audit: rework the audit queue handling audit: rename the queues and kauditd related functions audit: queue netlink multicast sends just like we do for unicast sends audit: fixup audit_init() audit: move kaudit thread start from auditd registration to kaudit init (#2) audit: add support for session ID user filter audit: fix formatting of AUDIT_CONFIG_CHANGE events audit: skip sessionid sentinel value when auto-incrementing audit: tame initialization warning len_abuf in audit_log_execve_info audit: less stack usage for /proc/*/loginuid

2016-12-14libceph: always signal completion when doneIlya Dryomov1-14/+11
r_safe_completion is currently, and has always been, signaled only if on-disk ack was requested. It's there for fsync and syncfs, which wait for in-flight writes to flush - all data write requests set ONDISK. However, the pool perm check code introduced in 4.2 sends a write request with only ACK set. An unfortunately timed syncfs can then hang forever: r_safe_completion won't be signaled because only an unsafe reply was requested. We could patch ceph_osdc_sync() to skip !ONDISK write requests, but that is somewhat incomplete and yet another special case. Instead, rename this completion to r_done_completion and always signal it when the OSD client is done with the request, whether unsafe, safe, or error. This is a bit cleaner and helps with the cancellation code. Reported-by: Yan, Zheng <zyan@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2016-12-13mac80211: don't call drv_set_default_unicast_key() for VLANsJohannes Berg1-1/+2
Since drivers know nothing about AP_VLAN interfaces, trying to call drv_set_default_unicast_key() just results in a warning and no call to the driver. Avoid the warning by not calling the driver for this on AP_VLAN interfaces. This means that drivers that somehow need this call for AP mode will fail to work properly in the presence of VLAN interfaces, but the current drivers don't seem to use it, and mac80211 will select and indicate the key - so drivers should be OK now.

2016-12-12libceph: verify authorize reply on connectIlya Dryomov1-0/+13
After sending an authorizer (ceph_x_authorize_a + ceph_x_authorize_b), the client gets back a ceph_x_authorize_reply, which it is supposed to verify to ensure the authenticity and protect against replay attacks. The code for doing this is there (ceph_x_verify_authorizer_reply(), ceph_auth_verify_authorizer_reply() + plumbing), but it is never invoked by the the messenger. AFAICT this goes back to 2009, when ceph authentication protocols support was added to the kernel client in 4e7a5dcd1bba ("ceph: negotiate authentication protocol; implement AUTH_NONE protocol"). The second param of ceph_connection_operations::verify_authorizer_reply is unused all the way down. Pass 0 to facilitate backporting, and kill it in the next commit.
