2019-02-28crypto: cavium/zip - fix collision with generic cra_driver_nameEric Biggers1-2/+4
The cavium/zip implementation of the deflate compression algorithm is incorrectly being registered under the generic driver name, which prevents the generic implementation from being registered with the crypto API when CONFIG_CRYPTO_DEV_CAVIUM_ZIP=y. Similarly the lzs algorithm (which does not currently have a generic implementation...) is incorrectly being registered as lzs-generic. Fix the naming collision by adding a suffix "-cavium" to the cra_driver_name of the cavium/zip algorithms.

2018-11-09crypto: cavium/nitrox - fix a DMA pool free failureWenwen Wang3-10/+31
In crypto_alloc_context(), a DMA pool is allocated through dma_pool_alloc() to hold the crypto context. The meta data of the DMA pool, including the pool used for the allocation 'ndev->ctx_pool' and the base address of the DMA pool used by the device 'dma', are then stored to the beginning of the pool. These meta data are eventually used in crypto_free_context() to free the DMA pool through dma_pool_free(). However, given that the DMA pool can also be accessed by the device, a malicious device can modify these meta data, especially when the device is controlled to deploy an attack. This can cause an unexpected DMA pool free failure. To avoid the above issue, this patch introduces a new structure crypto_ctx_hdr and a new field chdr in the structure nitrox_crypto_ctx hold the meta data information of the DMA pool after the allocation. Note that the original structure ctx_hdr is not changed to ensure the compatibility.

2018-06-12treewide: kzalloc_node() -> kcalloc_node()Kees Cook1-1/+1
The kzalloc_node() function has a 2-factor argument form, kcalloc_node(). This patch replaces cases of: kzalloc_node(a * b, gfp, node) with: kcalloc_node(a * b, gfp, node) as well as handling cases of: kzalloc_node(a * b * c, gfp, node) with: kzalloc_node(array3_size(a, b, c), gfp, node) as it's slightly less ugly than: kcalloc_node(array_size(a, b), c, gfp, node) This does, however, attempt to ignore constant size factors like: kzalloc_node(4 * 1024, gfp, node) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc_node( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc_node( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

After issuing a request an endless loop was used to read the completion state from memory which is asynchronously updated by the ZIP coprocessor. Add an upper bound to the retry attempts to prevent a CPU getting stuck forever in case of an error. Additionally, add a read memory barrier and a small delay between the reading attempts.

2018-04-21crypto: cavium - Fix fallout from CONFIG_VMAP_STACKJan Glauber1-8/+14
Enabling virtual mapped kernel stacks breaks the thunderx_zip driver. On compression or decompression the executing CPU hangs in an endless loop. The reason for this is the usage of __pa by the driver which does no longer work for an address that is not part of the 1:1 mapping. The zip driver allocates a result struct on the stack and needs to tell the hardware the physical address within this struct that is used to signal the completion of the request. As the hardware gets the wrong address after the broken __pa conversion it writes to an arbitrary address. The zip driver then waits forever for the completion byte to contain a non-zero value. Allocating the result struct from 1:1 mapped memory resolves this bug.

cpt_device_init() is never called in atomic context. The call chain ending up at cpt_device_init() is: [1] cpt_device_init() <- cpt_probe() cpt_probe() is only set as ".probe" in pci_driver structure "cpt_pci_driver". Despite never getting called from atomic context, cpt_device_init() calls mdelay(100), i.e. busy wait for 100ms. That is not necessary and can be replaced with msleep to avoid busy waiting.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman11-0/+11
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.

Every developer always thinks that _their_ code is so special and magical that it should be enabled by default. And most of them are completely and utterly wrong. That's definitely the case when you write a specialty driver for a very unsual "security processor". It does *not* get to mark itself as "default m". If you solve world hunger, and make a driver that cures people of cancer, by all means enable it by default. But afaik, the Cavium CNN55XX does neither.
