Subject: [PATCH for_v22 0/6] x86/sgx: Remove EADD worker and page copy
Date: Thu, 8 Aug 2019 15:13:34 -0700 [thread overview]
Message-ID: <20190808221340.29460-1-sean.j.christopherson@intel.com> (raw)
As suggested by Andy, remove the work queue in favor of handling the
entire EADD flow in the context of the ioctl(). After the worker is
gone, pass the source page/address directly to EADD instead of first
copying the data into kernel memory.
This applies on top the bug fix series I sent yesterday,
https://patchwork.kernel.org/cover/11082995/.
Sean Christopherson (6):
x86/sgx: Validate generic SECINFO immediately after copying from user
x86/sgx: Set SGX_ENCL_PAGE_TCS when allocating encl_page
x86/sgx: Move encl_page insertion into tree out of alloc flow
x86/sgx: Allocate encl_page prior to taking encl->lock
x86/sgx: Remove the EADD page worker
x86/sgx: Pass userspace source address directly to EADD
