2021-06-22RDMA/hns: Delete unnecessary branch of hns_roce_v2_query_qpYangyang Li
When query_qp is called by userspace, max_send_wr and max_send_sge are set to 0 by the kernel driver. However, the userspace does not use these two return values from the kernel driver, but uses its own calculated values. So there is no need for special treatment.

2021-06-22Merge branch 'mlx5_realtime_ts' into rdma.git for-nextJason Gunthorpe
Aharon Landau says: ==================== In case device supports only real-time timestamp, the kernel will fail to create QP despite rdma-core requested such timestamp type. It is because device returns free-running timestamp, and the conversion from free-running to real-time is performed in the user space.

2021-06-22RDMA/mlx5: Support real-time timestamp directly from the deviceAharon Landau
Currently, if the user asks for a real-time timestamp, the device will return a free-running one, and the timestamp will be translated to real-time in the user-space. When the device supports only real-time timestamp and not free-running, the creation of the QP will fail even though the user needs supported the real-time one. To prevent this, we will return the real-time timestamp directly from the device.

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. Without a flexible array, this looks like an attempt to perform a memcpy() read beyond the end of the packet->mad.data array: drivers/infiniband/core/user_mad.c: memcpy(packet->msg->mad, packet->mad.data, IB_MGMT_MAD_HDR); Switch from [0] to [] to use the appropriately handled type for trailing bytes.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Borislav Petkov: "A first set of urgent fixes to the FPU/XSTATE handling mess^W code. (There's a lot more in the pipe): - Prevent corruption of the XSTATE buffer in signal handling by validating what is being copied from userspace first. - Invalidate other task's preserved FPU registers on XRSTOR failure (#PF) because latter can still modify some of them. - Restore the proper PKRU value in case userspace modified it - Reset FPU state when signal restoring fails Other: - Map EFI boot services data memory as encrypted in a SEV guest so that the guest can access it and actually boot properly - Two SGX correctness fixes: proper resources freeing and a NUMA fix" * tag 'x86_urgent_for_v5.13_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm: Avoid truncating memblocks for SGX memory x86/sgx: Add missing xa_destroy() when virtual EPC is destroyed x86/fpu: Reset state for all signal restore failures x86/pkru: Write hardware init value to PKRU when xstate is init x86/process: Check PF_KTHREAD and not current->mm for kernel threads x86/fpu: Invalidate FPU state after a failed XRSTOR from a user buffer x86/fpu: Prevent state corruption in __fpu__restore_sig() x86/ioremap: Map EFI-reserved memory as encrypted for SEV

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "Fix initrd corruption caused by our recent change to use relative jump labels. Fix a crash using perf record on systems without a hardware PMU backend. Rework our 64-bit signal handling slighty to make it more closely match the old behaviour, after the recent change to use unsafe user accessors.
