Rui Miguel Silva	d6172283a4	optee: add writeback to valid memory type ... [ Upstream commit 853735e404 ] Only in smp systems the cache policy is setup as write alloc, in single cpu systems the cache policy is set as writeback and it is normal memory, so, it should pass the is_normal_memory check in the share memory registration. Add the right condition to make it work in no smp systems.

Andrey Konovalov	e426e9788e	UPSTREAM: tee/shm: untag user pointers in tee_shm_register ... (Upstream commit 78063a9dd9). This patch is a part of a series that extends kernel ABI to allow to pass tagged user pointers (with the top byte set to something else other than 0x00) as syscall arguments. tee_shm_register()->optee_shm_unregister()->check_mem_type() uses provided user pointers for vma lookups (via __check_mem_type()), which can only by done with untagged pointers. Untag user pointers in this function.

Zhizhou Zhang	39d4c1c0dd	tee: optee: avoid possible double list_del() ... [ Upstream commit b2d102bd01 ] This bug occurs when: - a new request arrives, one thread(let's call it A) is pending in optee_supp_req() with req->busy is initial value false. - tee-supplicant is killed, then optee_supp_release() is called, this function calls list_del(&req->link), and set supp->ctx to NULL. And it also wake up process A. - process A continues, it firstly checks supp->ctx which is NULL, then checks req->busy which is false, at last run list_del(&req->link). This triggers double list_del() and results kernel panic. For solve this problem, we rename req->busy to req->in_queue, and associate it with state of whether req is linked to supp->reqs. So we can just only check req->in_queue to make decision calling list_del() or not.

Arnd Bergmann	bad19e0d04	This pull request enables dynamic shared memory support in the TEE ... subsystem as a whole and in OP-TEE in particular. Global Platform TEE specification [1] allows client applications to register part of own memory as a shared buffer between application and TEE. This allows fast zero-copy communication between TEE and REE. But current implementation of TEE in Linux does not support this feature. Also, current implementation of OP-TEE transport uses fixed size pre-shared buffer for all communications with OP-TEE OS. This is okay in the most use cases. But this prevents use of OP-TEE in virtualized environments, because: a) We can't share the same buffer between different virtual machines b) Physically contiguous memory as seen by VM can be non-contiguous in reality (and as seen by OP-TEE OS) due to second stage of MMU translation. c) Size of this pre-shared buffer is limited. So, first part of this pull request adds generic register/unregister interface to tee subsystem. The second part adds necessary features into OP-TEE driver, so it can use not only static pre-shared buffer, but whole RAM to communicate with OP-TEE OS. This change is backwards compatible allowing older secure world or user space to work with newer kernels and vice versa.

But this prevents use of OP-TEE in virtualized environments, because: a) We can't share the same buffer between different virtual machines b) Physically contiguous memory as seen by VM can be non-contiguous in reality (and as seen by OP-TEE OS) due to second stage of MMU translation. c) Size of this pre-shared buffer is limited. So, first part of this pull request adds generic register/unregister interface to tee subsystem. The second part adds necessary features into OP-TEE driver, so it can use not only static pre-shared buffer, but whole RAM to communicate with OP-TEE OS. This change is backwards compatible allowing older secure world or user space to work with newer kernels and vice versa.

Volodymyr Babchuk	f58e236c9d	tee: optee: enable dynamic SHM support ... Previous patches added various features that are needed for dynamic SHM. Dynamic SHM allows Normal World to share any buffers with OP-TEE. While original design suggested to use pre-allocated region (usually of 1M to 2M of size), this new approach allows to use all non-secure RAM for command buffers, RPC allocations and TA parameters. This patch checks capability OPTEE_SMC_SEC_CAP_DYNAMIC_SHM. If it was set by OP-TEE, then kernel part of OP-TEE will use kernel page allocator to allocate command buffers. Also it will set TEE_GEN_CAP_REG_MEM capability to tell userspace that it supports shared memory registration.

Thus, it is possible for supplicant to provide part of own memory when OP-TEE asks to allocate a shared buffer. This patch adds support for such feature into RPC handling code. Now when OP-TEE asks supplicant to allocate shared buffer, supplicant can use TEE_IOC_SHM_REGISTER to provide such buffer. RPC handler is aware of this, so it will pass list of allocated pages to OP-TEE.

Volodymyr Babchuk	06ca79179c	tee: optee: add shared buffer registration functions ... This change adds ops for shm_(un)register functions in tee interface. Client application can use these functions to (un)register an own shared buffer in OP-TEE address space. This allows zero copy data sharing between Normal and Secure Worlds. Please note that while those functions were added to optee code, it does not report to userspace that those functions are available. OP-TEE code does not set TEE_GEN_CAP_REG_MEM flag. This flag will be enabled only after all other features of dynamic shared memory will be implemented in subsequent patches. Of course user can ignore presence of TEE_GEN_CAP_REG_MEM flag and try do call those functions. This is okay, driver will register shared buffer in OP-TEE, but any attempts to use this shared buffer will fail.

Greg Kroah-Hartman	b24413180f	License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.
