2019-06-20staging: rtl8712: r8712_setopmode_cmd(): Change return typeNishka Dasgupta
Change return type of function r8712_setopmode_cmd() from u8 to void as its return value is never stored or checked or otherwise used. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-06-20staging: rtl8712: Change (r8712)_enqueue_cmd to voidNishka Dasgupta
Change the return types of r8712_enqueue_cmd to void as the return value of r8712_enqueue_cmd is never stored, checked, or otherwise used. Also change the return type of _enqueue_cmd to void as it is only called by r8712_enqueue_cmd which does not do anything with the return value except return it itself. Modify return statements in both functions accordingly. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-06-20staging: rtl8712: r8712_joinbss_cmd(): Change return values and typeNishka Dasgupta
Change return values of function r8712_joinbss_cmd from _SUCCESS/_FAIL to 0/-ENOMEM respectively. Change return type from u8 to int to accommodate return of -ENOMEM. Similarly, change the return values (_SUCCESS to 0 and _FAIL to -ENOMEM or -EINVAL) and type (sint to int) of the call site of r8712_joinbss_cmd, r8712_select_and_join_from_scan, as one of the branches of r8712_select_and_join_from_scan directly returns the return value of r8712_joinbss_cmd. Modify the call sites of r8712_select_and_join_from_scan to check for 0 instead of _SUCCESS. Issue found with Coccinelle.

2019-06-20staging: rtl8723bs: os_dep: ioctl_linux: make use of kzallocHariprasad Kelam
This patch is a cleanup which replaces rtw_malloc(wep_total_len) with kzalloc() and removes the memset(). The rtw_malloc() does GFP_ATOMIC allocations when in_atomic() is true. But as the comments for in_atomic() describe, the in_atomic() check should not be used in driver code. The in_atomic() check is not accurate when preempt is disabled. In this code we are not in IRQ context and we are not holding any spin_locks so GFP_KERNEL is safe.

2019-06-20KVM: PPC: Book3S HV: Invalidate ERAT when flushing guest TLB entriesSuraj Jitindar Singh
When a guest vcpu moves from one physical thread to another it is necessary for the host to perform a tlb flush on the previous core if another vcpu from the same guest is going to run there. This is because the guest may use the local form of the tlb invalidation instruction meaning stale tlb entries would persist where it previously ran. This is handled on guest entry in kvmppc_check_need_tlb_flush() which calls flush_guest_tlb() to perform the tlb flush. Previously the generic radix__local_flush_tlb_lpid_guest() function was used, however the functionality was reimplemented in flush_guest_tlb() to avoid the trace_tlbie() call as the flushing may be done in real mode. The reimplementation in flush_guest_tlb() was missing an erat invalidation after flushing the tlb. This lead to observable memory corruption in the guest due to the caching of stale translations. Fix this by adding the erat invalidation.

2019-06-19inet: clear num_timeout reqsk_alloc()Eric Dumazet
KMSAN caught uninit-value in tcp_create_openreq_child() [1] This is caused by a recent change, combined by the fact that TCP cleared num_timeout, num_retrans and sk fields only when a request socket was about to be queued. Under syncookie mode, a temporary request socket is used, and req->num_timeout could contain garbage. Lets clear these three fields sooner, there is really no point trying to defer this and risk other bugs.

2019-06-19PCI/P2PDMA: Ignore root complex whitelist when an IOMMU is presentLogan Gunthorpe
Presently, there is no path to DMA map P2PDMA memory, so if a TLP targeting this memory hits the root complex and an IOMMU is present, the IOMMU will reject the transaction, even if the RC would support P2PDMA. So until the kernel knows to map these DMA addresses in the IOMMU, we should not enable the whitelist when an IOMMU is present.

2019-06-19ipv6: Default fib6_type to RTN_UNICAST when not setDavid Ahern
A user reported that routes are getting installed with type 0 (RTN_UNSPEC) where before the routes were RTN_UNICAST. One example is from accel-ppp which apparently still uses the ioctl interface and does not set rtmsg_type. Another is the netlink interface where ipv6 does not require rtm_type to be set (v4 does). Prior to the commit in the Fixes tag the ipv6 stack converted type 0 to RTN_UNICAST, so restore that behavior.

Julian Wiedmann says: ==================== net/af_iucv: fixes 2019-06-18 I spent a few cycles on transmit problems for af_iucv over regular netdevices - please apply the following fixes to -net. The first patch allows for skb allocations outside of GFP_DMA, while the second patch respects that drivers might use skb_cow_head() and/or want additional dev->needed_headroom. Patch 3 is for a separate issue, where we didn't setup some of the netdevice-specific infrastructure when running as a z/VM guest. ==================== Signed-off-by: David S.

2019-06-19net/af_iucv: always register net_device notifierJulian Wiedmann
Even when running as VM guest (ie pr_iucv != NULL), af_iucv can still open HiperTransport-based connections. For robust operation these connections require the af_iucv_netdev_notifier, so register it unconditionally. Also handle any error that register_netdevice_notifier() returns.

2019-06-19net/af_iucv: build proper skbs for HiperTransportJulian Wiedmann
The HiperSockets-based transport path in af_iucv is still too closely entangled with qeth. With commit a647a02512ca ("s390/qeth: speed-up L3 IQD xmit"), the relevant xmit code in qeth has begun to use skb_cow_head(). So to avoid unnecessary skb head expansions, af_iucv must learn to 1) respect dev->needed_headroom when allocating skbs, and 2) drop the header reference before cloning the skb. While at it, also stop hard-coding the LL-header creation stage and just use the appropriate helper.

2019-06-19net/af_iucv: remove GFP_DMA restriction for HiperTransportJulian Wiedmann
af_iucv sockets over z/VM IUCV require that their skbs are allocated in DMA memory. This restriction doesn't apply to connections over HiperSockets. So only set this limit for z/VM IUCV sockets, thereby increasing the likelihood that the large (and linear!) allocations for HiperTransport messages succeed.
