Steffen Klassert says: ==================== ipv6: Return an error when adding an already existing tunnel The ipv6 tunnel locate functions should not return an existing tunnel if create is true. Otherwise it is possible to add the same tunnel multiple times without getting an error. All our ipv6 tunnels have this bug from the very beginning. Only the sit tunnel was fixed some years ago with: commit 8db99e57 ("sit: Fail to create tunnel, if it already exists"). This patchset fixes the remaining ipv6 tunnels. ==================== Signed-off-by:

When the HCA is configured in SRIOV IB mode (that is, at least one of the ports is IB) and the probe_vf module param isn't specified, mlx4_init_one() failed because of the following condition: if (ib_ports && (num_vfs_argc > 1 || probe_vfs_argc > 1)) { ..... } The root cause for that is a mistake in the initialization of num_vfs_argc and probe_vfs_argc. When num_vfs / probe_vf aren't given, their argument count counterpart should be 0, fix that. Fixes: dd41cc3b ('net/mlx4: Adapt num_vfs/probed_vf params for single port VF') Signed-off-by:

In macvtap device delete and open calls can race and this causes a list curruption of the vlan queue_list. The race intself is triggered by the idr accessors that located the vlan device. The device is stored into and removed from the idr under both an rtnl and a mutex. However, when attempting to locate the device in idr, only a mutex is taken. As a result, once cpu perfoming a delete may take an rtnl and wait for the mutex, while another cput doing an open() will take the idr mutex first to fetch the device pointer and later take an rtnl to add a queue for the device which may have just gotten deleted. With this patch, we now hold the rtnl for the duration of the macvtap_open() call thus making sure that open will not race with delete. CC: Michael S.

When we try to add an already existing tunnel, we don't return an error. Instead we continue and call ip_tunnel_update(). This means that we can change existing tunnels by adding the same tunnel multiple times. It is even possible to change the tunnel endpoints of the fallback device.

Pull networking fixes from David Miller: "Here is a quick pull request primarily meant to address the deconfig fallout from changing SCSI_NETLINK from being used via 'select' to being used via 'depends'. I applied a set of 5 patches written by Michal Marek, and then I carefully audited all of the remaining config files, basically: 1) I scanned every arch config file, and if it mentioned CONFIG_INET or CONFIG_UNIX, I made sure it had CONFIG_NET=y 2) After that, I scanned every arch config file, and if it did not have CONFIG_NET=y I made sure it did not reference any networking config options.

- fix BPF_LD|ABS|IND from negative offsets: make sure to sign extend lower 32 bits in 64-bit register before calling C helpers from JITed code, otherwise 'int k' argument of bpf_internal_load_pointer_neg_helper() function will be added as large unsigned integer, causing packet size check to trigger and abort the program. It's worth noting that JITed code for 'A = A op K' will affect upper 32 bits differently depending whether K is simm13 or not. Since small constants are sign extended, whereas large constants are stored in temp register and zero extended. That is ok and we don't have to pay a penalty of sign extension for every sethi, since all classic BPF instructions have 32-bit semantics and we only need to set correct upper bits when transitioning from JITed code into C. - though instructions 'A &= 0' and 'A *= 0' are odd, JIT compiler should not optimize them out Signed-off-by:

This was bisected down to the percpu changes for blk_mq_queue_enter(), and the fact we now suffer an RCU grace period when killing a queue. SCSI creates and destroys tons of queues, so this let to 10s of seconds of stalls at boot for some. Tejun has a real fix for this, but it's too involved for 3.17.

blk-mq uses percpu_ref for its usage counter which tracks the number of in-flight commands and used to synchronously drain the queue on freeze. percpu_ref shutdown takes measureable wallclock time as it involves a sched RCU grace period. This means that draining a blk-mq takes measureable wallclock time. One would think that this shouldn't matter as queue shutdown should be a rare event which takes place asynchronously w.r.t. userland. Unfortunately, SCSI probing involves synchronously setting up and then tearing down a lot of request_queues back-to-back for non-existent LUNs. This means that SCSI probing may take more than ten seconds when scsi-mq is used. This will be properly fixed by implementing a mechanism to keep q->mq_usage_counter in atomic mode till genhd registration; however, that involves rather big updates to percpu_ref which is difficult to apply late in the devel cycle (v3.17-rc6 at the moment). As a stop-gap measure till the proper fix can be implemented in the next cycle, this patch introduces __percpu_ref_kill_expedited() and makes blk_mq_freeze_queue() use it. This is heavy-handed but should work for testing the experimental SCSI blk-mq implementation. Signed-off-by:

The "by8" implementation introduced in commit 22cddcc7 ("crypto: aes - AES CTR x86_64 "by8" AVX optimization") is failing crypto tests as it handles counter block overflows differently. It only accounts the right most 32 bit as a counter -- not the whole block as all other implementations do. This makes it fail the cryptomgr test #4 that specifically tests this corner case. As we're quite late in the release cycle, just disable the "by8" variant for now. Reported-by:

If the ccp is built as a built-in module, then ccp-crypto (whether built as a module or a built-in module) will be able to load and it will register its crypto algorithms. If the system does not have a CCP this will result in -ENODEV being returned whenever a command is attempted to be queued by the registered crypto algorithms. Add an API, ccp_present(), that checks for the presence of a CCP on the system. The ccp-crypto module can use this to determine if it should register it's crypto alogorithms.
