2016-07-18crypto: aead - Add skcipher null for IV generatorsHerbert Xu
This patch adds an skcipher null object alongside the existing null blkcipher so that IV generators using it can switch over to skcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-07-18crypto: chacha20poly1305 - Use skcipherHerbert Xu
This patch converts chacha20poly1305 to use the new skcipher interface as opposed to ablkcipher. It also fixes a buglet where we may end up with an async poly1305 when the user asks for a async algorithm. This shouldn't be a problem yet as there aren't any async implementations of poly1305 out there. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2016-07-18crypto: authencesn - Use skcipherHerbert Xu
This patch converts authencesn to use the new skcipher interface as opposed to ablkcipher. It also fixes a little bug where if a sync version of authencesn is requested we may still end up using an async ahash. This should have no effect as none of the authencesn users can request for a sync authencesn. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2016-07-18crypto: aead - Add chunk sizeHerbert Xu
This patch adds a chunk size parameter to aead algorithms, just like the chunk size for skcipher algorithms. However, unlike skcipher we do not currently export this to AEAD users. It is only meant to be used by AEAD implementors for now. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-07-18crypto: null - Add new default null skcipherHerbert Xu
Current the default null skcipher is actually a crypto_blkcipher. This patch creates a synchronous crypto_skcipher version of the null cipher which unfortunately has to settle for the name skcipher2. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-07-18crypto: skcipher - Add low-level skcipher interfaceHerbert Xu
This patch allows skcipher algorithms and instances to be created and registered with the crypto API. They are accessible through the top-level skcipher interface, along with ablkcipher/blkcipher algorithms and instances. This patch also introduces a new parameter called chunk size which is meant for ciphers such as CTR and CTS which ostensibly can handle arbitrary lengths, but still behave like block ciphers in that you can only process a partial block at the very end. For these ciphers the block size will continue to be set to 1 as it is now while the chunk size will be set to the underlying block size. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2016-07-18s390/cio/chp : Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
The workqueue "chp_wq" is involved in performing pending configure tasks for channel paths. It has a single work item(&cfg_work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference.

2016-07-18KEYS: Fix for erroneous trust of incorrectly signed X.509 certsMat Martineau
Arbitrary X.509 certificates without authority key identifiers (AKIs) can be added to "trusted" keyrings, including IMA or EVM certs loaded from the filesystem. Signature verification is currently bypassed for certs without AKIs. Trusted keys were recently refactored, and this bug is not present in 4.6. restrict_link_by_signature should return -ENOKEY (no matching parent certificate found) if the certificate being evaluated has no AKIs, instead of bypassing signature checks and returning 0 (new certificate accepted).

2016-07-16net: cavium: liquidio: Avoid dma_unmap_single on uninitialized ndataFlorian Fainelli
The label lio_xmit_failed is used 3 times through liquidio_xmit() but it always makes a call to dma_unmap_single() using potentially uninitialized variables from "ndata" variable. Out of the 3 gotos, 2 run after ndata has been initialized, and had a prior dma_map_single() call. Fix this by adding a new error label: lio_xmit_dma_failed which does this dma_unmap_single() and then processed with the lio_xmit_failed fallthrough.

2016-07-16vlan: use a valid default mtu value for vlan over macsecPaolo Abeni
macsec can't cope with mtu frames which need vlan tag insertion, and vlan device set the default mtu equal to the underlying dev's one. By default vlan over macsec devices use invalid mtu, dropping all the large packets. This patch adds a netif helper to check if an upper vlan device needs mtu reduction. The helper is used during vlan devices initialization to set a valid default and during mtu updating to forbid invalid, too bit, mtu values. The helper currently only check if the lower dev is a macsec device, if we get more users, we need to update only the helper (possibly reserving an additional IFF bit).

2016-07-16Revert "KVM: SVM: fix trashing of MSR_TSC_AUX"Radim Krčmář
This reverts commit 9770404a0061ec46dec6e15c4b07731ce2e2d7bb. The reverted patch is not needed as only userspace uses RDTSCP and MSR_TSC_AUX is in host_save_user_msrs[] and therefore properly saved in svm_vcpu_load() and restored in svm_vcpu_put() before every switch to userspace. The reverted patch did not allow the kernel to use RDTSCP in the future, because of missed trashing in svm_set_msr() and 64-bit ifdef. This reverts commit 2b23c3a6e3eb2fba77eb35fdfa3d71a9aa3f33b7. 2b23c3a6e3eb ("KVM: SVM: do not set MSR_TSC_AUX on 32-bit builds") is a build fix for 9770404a0061 and reverting them separately would only break more bisections.

When building under W=1, the lack of lkdtm.h in lkdtm_usercopy.c and lkdtm_rodata.c was discovered. This fixes the issue and consolidates the common header and the pr_fmt macro for simplicity and regularity across each test source file. Signed-off-by: Kees Cook <keescook@chromium.org>
2016-07-15lkdtm: hide unused functionsArnd Bergmann
A conversion of the lkdtm core module added an "#ifdef CONFIG_KPROBES" check, but a number of functions then become unused: drivers/misc/lkdtm_core.c:340:16: error: 'lkdtm_debugfs_entry' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:122:12: error: 'jp_generic_ide_ioctl' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:114:12: error: 'jp_scsi_dispatch_cmd' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:106:12: error: 'jp_hrtimer_start' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:97:22: error: 'jp_shrink_inactive_list' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:89:13: error: 'jp_ll_rw_block' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:83:13: error: 'jp_tasklet_action' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:75:20: error: 'jp_handle_irq_event' defined but not used [-Werror=unused-function] drivers/misc/lkdtm_core.c:68:21: error: 'jp_do_irq' defined but not used [-Werror=unused-function] This adds the same #ifdef everywhere. There is probably a better way to do the same thing, but for now this avoids the new warnings.

2016-07-15mlxsw: spectrum: Prevent invalid ingress buffer mappingIdo Schimmel
Packets entering the switch are mapped to a Switch Priority (SP) according to their PCP value (untagged frames are mapped to SP 0). The packets are classified to a priority group (PG) buffer in the port's headroom according to their SP. The switch maintains another mapping (SP to IEEE priority), which is used to generate PFC frames for lossless PGs. This mapping is initialized to IEEE = SP % 8. Therefore, when mapping SP 'x' to PG 'y' we create a situation in which an IEEE priority is mapped to two different PGs: IEEE 'x' ---> SP 'x' ---> PG 'y' IEEE 'x' ---> SP 'x + 8' ---> PG '0' (default) Which is invalid, as a flow can use only one PG buffer. Fix this by mapping both SP 'x' and 'x + 8' to the same PG buffer.

2016-07-15mlxsw: spectrum: Don't emit errors when PFC is disabledIdo Schimmel
We can't have PAUSE frames and PFC both enabled on the same port, but the fact that ieee_setpfc() was called doesn't necessarily mean PFC is enabled. Only emit errors when PAUSE frames and PFC are enabled simultaneously.
