2020-08-17irqchip: Fix probing deferal when using IRQCHIP_PLATFORM_DRIVER helpersMarc Zyngier
When probing an interrupt controller that is behind a parent, we try to check whether the parent domain is available as an indication that we can actually try to probe. Unfortunately, we are checking this with the firmware node of the about to be probed device, not the parent. This is obviously bound to fail. Instead, use the parent node.

2020-08-16tipc: fix uninit skb->data in tipc_nl_compat_dumpit()Cong Wang
__tipc_nl_compat_dumpit() has two callers, and it expects them to pass a valid nlmsghdr via arg->data. This header is artificial and crafted just for __tipc_nl_compat_dumpit(). tipc_nl_compat_publ_dump() does so by putting a genlmsghdr as well as some nested attribute, TIPC_NLA_SOCK. But the other caller tipc_nl_compat_dumpit() does not, this leaves arg->data uninitialized on this call path. Fix this by just adding a similar nlmsghdr without any payload in tipc_nl_compat_dumpit(). This bug exists since day 1, but the recent commit 6ea67769ff33 ("net: tipc: prepare attrs in __tipc_nl_compat_dumpit()") makes it easier to appear.

2020-08-17powerpc/perf: Add support for outputting extended regs in perf intr_regsAnju T Sudhakar
Add support for perf extended register capability in powerpc. The capability flag PERF_PMU_CAP_EXTENDED_REGS, is used to indicate the PMU which support extended registers. The generic code define the mask of extended registers as 0 for non supported architectures. Patch adds extended regs support for power9 platform by exposing MMCR0, MMCR1 and MMCR2 registers. REG_RESERVED mask needs update to include extended regs. PERF_REG_EXTENDED_MASK, contains mask value of the supported registers, is defined at runtime in the kernel based on platform since the supported registers may differ from one processor version to another and hence the MASK value.

2020-08-16net: xdp: pull ethernet header off packet after computing skb->protocolJason A. Donenfeld
When an XDP program changes the ethernet header protocol field, eth_type_trans is used to recalculate skb->protocol. In order for eth_type_trans to work correctly, the ethernet header must actually be part of the skb data segment, so the code first pushes that onto the head of the skb. However, it subsequently forgets to pull it back off, making the behavior of the passed-on packet inconsistent between the protocol modifying case and the static protocol case. This patch fixes the issue by simply pulling the ethernet header back off of the skb head.

2020-08-16bonding: fix a potential double-unregisterCong Wang
When we tear down a network namespace, we unregister all the netdevices within it. So we may queue a slave device and a bonding device together in the same unregister queue. If the only slave device is non-ethernet, it would automatically unregister the bonding device as well. Thus, we may end up unregistering the bonding device twice.

General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads. Some applications don't really like that, so the io_read() code now handles short reads internally, and got a cleanup along the way so that it's now easier to read (and documented).

2020-08-16parisc: fix PMD pages allocation by restoring pmd_alloc_one()Mike Rapoport
Commit 1355c31eeb7e ("asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()") converted parisc to use generic version of pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for PMD. Restore the original version of pmd_alloc_one() for parisc, just use GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and memset.

2020-08-15io_uring: short circuit -EAGAIN for blocking read attemptJens Axboe
One case was missed in the short IO retry handling, and that's hitting -EAGAIN on a blocking attempt read (eg from io-wq context). This is a problem on sockets that are marked as non-blocking when created, they don't carry any REQ_F_NOWAIT information to help us terminate them instead of perpetually retrying.

2020-08-15io_uring: sanitize double poll handlingJens Axboe
There's a bit of confusion on the matching pairs of poll vs double poll, depending on if the request is a pure poll (IORING_OP_POLL_ADD) or poll driven retry. Add io_poll_get_double() that returns the double poll waitqueue, if any, and io_poll_get_single() that returns the original poll waitqueue. With that, remove the argument to io_poll_remove_double(). Finally ensure that wait->private is cleared once the double poll handler has run, so that remove knows it's already been seen.
