2019-01-25arm64: KVM: Don't generate UNDEF when LORegion feature is presentMarc Zyngier
We currently hide the LORegion feature, and generate an UNDEF if the guest dares using the corresponding registers. This is a bit extreme, as ARMv8.1 guarantees the feature to be present. The guest should check the feature register before doing anything, but we could also give the guest some slack (read "allow the guest to be a bit stupid"). So instead of unconditionnaly deliver an exception, let's only do it when the host doesn't support LORegion at all (or when the feature has been sanitized out), and treat the registers as RAZ/WI otherwise (with the exception of LORID_EL1 being RO).

2019-01-25nl80211: fix NLA_POLICY_NESTED() argumentsJohannes Berg
syzbot reported an out-of-bounds read when passing certain malformed messages into nl80211. The specific place where this happened isn't interesting, the problem is that nested policy parsing was referring to the wrong maximum attribute and thus the policy wasn't long enough. Fix this by referring to the correct attribute. Since this is really not necessary, I'll come up with a separate patch to just pass the policy instead of both, in the common case we can infer the maxattr from the size of the policy array.

Tariq Toukan says: ==================== mlx4_core fixes for 5.0-rc This patchset includes two fixes for the mlx4_core driver. First patch by Aya fixes inaccurate parsing of some FW fields, mistakenly including additional (mostly reserved) bits. Second patch by Jack fixes a wrong (yet harmless) error handling of calls to copy_to_user() during the CQs init stage.

2019-01-24net/mlx4_core: Fix error handling when initializing CQ bufs in the driverJack Morgenstein
Procedure mlx4_init_user_cqes() handles returns by copy_to_user incorrectly. copy_to_user() returns the number of bytes not copied. Thus, a non-zero return should be treated as a -EFAULT error (as is done elsewhere in the kernel). However, mlx4_init_user_cqes() error handling simply returns the number of bytes not copied (instead of -EFAULT). Note, though, that this is a harmless bug: procedure mlx4_alloc_cq() (which is the only caller of mlx4_init_user_cqes()) treats any non-zero return as an error, but that returned error value is processed internally, and not passed further up the call stack. In addition, fixes the following sparse warning: warning: incorrect type in argument 1 (different address spaces) expected void [noderef] <asn:1>*to got void *buf Fixes: e45678973dcb ("{net, IB}/mlx4: Initialize CQ buffers in the driver when possible") Reported by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

2019-01-24net/mlx4_core: Add masking for a few queries on HCA capsAya Levin
Driver reads the query HCA capabilities without the corresponding masks. Without the correct masks, the base addresses of the queues are unaligned. In addition some reserved bits were wrongly read. Using the correct masks, ensures alignment of the base addresses and allows future firmware versions safe use of the reserved bits.

2019-01-24arm64: dts: add msm8996 compatible to gicv3Srinivas Kandagatla
Add compatible to gicv3 node to enable quirk required to restrict writing to GICR_WAKER register which is restricted on msm8996 SoC in Hypervisor. With this quirk MSM8996 can at least boot out of mainline, which can help community to work with boards based on MSM8996. Without this patch Qualcomm DB820c board reboots on mainline.

2019-01-24sctp: set flow sport from saddr only when it's 0Xin Long
Now sctp_transport_pmtu() passes transport->saddr into .get_dst() to set flow sport from 'saddr'. However, transport->saddr is set only when transport->dst exists in sctp_transport_route(). If sctp_transport_pmtu() is called without transport->saddr set, like when transport->dst doesn't exists, the flow sport will be set to 0 from transport->saddr, which will cause a wrong route to be got. Commit 6e91b578bf3f ("sctp: re-use sctp_transport_pmtu in sctp_transport_route") made the issue be triggered more easily since sctp_transport_pmtu() would be called in sctp_transport_route() after that. In gerneral, fl4->fl4_sport should always be set to htons(asoc->base.bind_addr.port), unless transport->asoc doesn't exist in sctp_v4/6_get_dst(), which is the case: sctp_ootb_pkt_new() -> sctp_transport_route() For that, we can simply handle it by setting flow sport from saddr only when it's 0 in sctp_v4/6_get_dst().

2019-01-24sctp: set chunk transport correctly when it's a new asocXin Long
In the paths: sctp_sf_do_unexpected_init() -> sctp_make_init_ack() sctp_sf_do_dupcook_a/b()() -> sctp_sf_do_5_1D_ce() The new chunk 'retval' transport is set from the incoming chunk 'chunk' transport. However, 'retval' transport belong to the new asoc, which is a different one from 'chunk' transport's asoc. It will cause that the 'retval' chunk gets set with a wrong transport. Later when sending it and because of Commit b9fd683982c9 ("sctp: add sctp_packet_singleton"), sctp_packet_singleton() will set some fields, like vtag to 'retval' chunk from that wrong transport's asoc. This patch is to fix it by setting 'retval' transport correctly which belongs to the right asoc in sctp_make_init_ack() and sctp_sf_do_5_1D_ce().
