* ktime: Get rid of ktime_equal()Thomas Gleixner2016-12-251-1/+1

* ktime: Cleanup ktime_set() usageThomas Gleixner2016-12-255-7/+7
| | | | | | | | | | ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.

* ktime: Get rid of the unionThomas Gleixner2016-12-2514-30/+30
| | | | | | | | | | | | | | | ktime is a union because the initial implementation stored the time in scalar nanoseconds on 64 bit machine and in a endianess optimized timespec variant for 32bit machines. The Y2038 cleanup removed the timespec variant and switched everything to scalar nanoseconds. The union remained, but become completely pointless. Get rid of the union and just keep ktime_t as simple typedef of type s64. The conversion was done with coccinelle and some manual mopping up.

* sctp: fix recovering from 0 win with small data chunksMarcelo Ricardo Leitner2016-12-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if SCTP closes the receive window with window pressure, mostly caused by excessive skb overhead on payload/overheads ratio, SCTP will close the window abruptly while saving the delta on rwnd_press. It will start recovering rwnd as the chunks are consumed by the application and the rwnd_press will be only recovered after rwnd reach the same value as of rwnd_press, mostly to prevent silly window syndrome. Thing is, this is very inefficient with small data chunks, as with those it will never reach back that value, and thus it will never recover from such pressure. This means that we will not issue window updates when recovering from 0 window and will rely on a sender retransmit to notice it. The fix here is to remove such threshold, as no value is good enough: it depends on the (avg) chunk sizes being used. Test with netperf -t SCTP_STREAM -- -m 1, and trigger 0 window by sending SIGSTOP to netserver, sleep 1.2, and SIGCONT. Rate limited to 845kbps, for visibility. Capture done at netserver side.

* sctp: do not loose window information if in rwnd_overMarcelo Ricardo Leitner2016-12-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible that we receive a packet that is larger than current window. If it's the first packet in this way, it will cause it to increase rwnd_over. Then, if we receive another data chunk (specially as SCTP allows you to have one data chunk in flight even during 0 window), rwnd_over will be overwritten instead of added to. In the long run, this could cause the window to grow bigger than its initial size, as rwnd_over would be charged only for the last received data chunk while the code will try open the window for all packets that were received and had its value in rwnd_over overwritten. This, then, can lead to the worsening of payload/buffer ratio and cause rwnd_press to kick in more often. The fix is to sum it too, same as is done for rwnd_press, so that if we receive 3 chunks after closing the window, we still have to release that same amount before re-opening it.

* neigh: Send netevent after marking neigh as deadIdo Schimmel2016-12-231-0/+1
| | | | | | | | | | | | | | | | | | neigh_cleanup_and_release() is always called after marking a neighbour as dead, but it only notifies user space and not in-kernel listeners of the netevent notification chain. This can cause multiple problems. In my specific use case, it causes the listener (a switch driver capable of L3 offloads) to believe a neighbour entry is still valid, and is thus erroneously kept in the device's table. Fix that by sending a netevent after marking the neighbour as dead.

We can notice that old kernels were immune to this bug, because TSQ_QUEUED was cleared after a bh_lock_sock(sk)/bh_unlock_sock(sk) section, but they could have missed a kick to write additional bytes, when NIC interrupts for a given flow are spread to multiple cpus.

* sctp: not copying duplicate addrs to the assoc's bind address listXin Long2016-12-202-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | sctp.local_addr_list is a global address list that is supposed to include all the local addresses. sctp updates this list according to NETDEV_UP/ NETDEV_DOWN notifications. However, if multiple NICs have the same address, the global list would have duplicate addresses. Even if for one NIC, promote secondaries in __inet_del_ifa can also lead to accumulating duplicate addresses. When sctp binds address 'ANY' and creates a connection, it copies all the addresses from global list into asoc's bind addr list, which makes sctp pack the duplicate addresses into INIT/INIT_ACK packets. This patch is to filter the duplicate addresses when copying the addrs from global list in sctp_copy_local_addr_list and unpacking addr_param from cookie in sctp_raw_to_bind_addrs to asoc's bind addr list. Note that we can't filter the duplicate addrs when global address list gets updated, As NETDEV_DOWN event may remove an addr that still exists in another NIC.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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". Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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>

We still can't take that GFP_KERNEL allocation though. Both ceph_crypto_key_clone() and ceph_crypto_key_decode() are called from GFP_NOFS context, so resort to memalloc_noio_{save,restore}() here.
