This reverts commit 5c9fa16e8abd342ce04dc830c1ebb2a03abf6c05. Since PROT_SAO can still be useful for certain classes of software, reintroduce it. Concerns about guest migration for LPARs using SAO will be addressed next.

2020-08-24binfmt_flat: revert "binfmt_flat: don't offset the data start"Max Filippov1-8/+12
binfmt_flat loader uses the gap between text and data to store data segment pointers for the libraries. Even in the absence of shared libraries it stores at least one pointer to the executable's own data segment. Text and data can go back to back in the flat binary image and without offsetting data segment last few instructions in the text segment may get corrupted by the data segment pointer. Fix it by reverting commit a2357223c50a ("binfmt_flat: don't offset the data start").

RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values and restores them either when leaving the run loop, on preemption or when going out to user space. MSR_TSX_AUX is part of that lazy MSR set, so after writing the guest value and before the lazy restore any exception using the paranoid entry will read the guest value and use it as CPU number to retrieve the GSBASE value for the current CPU when FSGSBASE is enabled. As RDPID is only used in that particular entry path, there is no reason to burden VMENTER/EXIT with two extra MSR writes. Remove the RDPID optimization, which is not even backed by numbers from the paranoid entry path instead" * tag 'x86-urgent-2020-08-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/64: Do not use RDPID in paranoid entry to accomodate KVM

2020-08-23io_uring: don't recurse on tsk->sighand->siglock with signalfdJens Axboe1-6/+16
If an application is doing reads on signalfd, and we arm the poll handler because there's no data available, then the wakeup can recurse on the tasks sighand->siglock as the signal delivery from task_work_add() will use TWA_SIGNAL and that attempts to lock it again. We can detect the signalfd case pretty easily by comparing the poll->head wait_queue_head_t with the target task signalfd wait queue. Just use normal task wakeup for this case.

2020-08-22epoll: Keep a reference on files added to the check listMarc Zyngier1-2/+9
When adding a new fd to an epoll, and that this new fd is an epoll fd itself, we recursively scan the fds attached to it to detect cycles, and add non-epool files to a "check list" that gets subsequently parsed. However, this check list isn't completely safe when deletions can happen concurrently. To sidestep the issue, make sure that a struct file placed on the check list sees its f_count increased, ensuring that a concurrent deletion won't result in the file disapearing from under our feet.

Currently the nexthop code will use an empty NHA_GROUP attribute, but it requires at least 1 entry in order to function properly. Otherwise we end up derefencing null or random pointers all over the place due to not having any nh_grp_entry members allocated, nexthop code relies on having at least the first member present. Empty NHA_GROUP doesn't make any sense so just disallow it. Also add a WARN_ON for any future users of nexthop_create_group().

The null check on a failed workqueue create is currently null checking hdev->cq_wq rather than the pointer hdev->cq_wq[i] and so the test will never be true on a failed workqueue create.

In Gaudi, the default max power setting is different between PCI and PMC cards. Therefore, the driver need to set the default after knowing what is the card type.
