2022-02-15kbuild: replace $(if A,A,B) with $(or A,B)Masahiro Yamada
$(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu>
2021-09-14usb: testusb: Fix for showing the connection speedFaizel K B
testusb' application which uses 'usbtest' driver reports 'unknown speed' from the function 'find_testdev'. The variable 'entry->speed' was not updated from the application. The IOCTL mentioned in the FIXME comment can only report whether the connection is low speed or not. Speed is read using the IOCTL USBDEVFS_GET_SPEED which reports the proper speed grade. The call is implemented in the function 'handle_testdev' where the file descriptor was availble locally. Sample output is given below where 'high speed' is printed as the connected speed. sudo ./testusb -a high speed /dev/bus/usb/001/011 0 /dev/bus/usb/001/011 test 0, 0.000015 secs /dev/bus/usb/001/011 test 1, 0.194208 secs /dev/bus/usb/001/011 test 2, 0.077289 secs /dev/bus/usb/001/011 test 3, 0.170604 secs /dev/bus/usb/001/011 test 4, 0.108335 secs /dev/bus/usb/001/011 test 5, 2.788076 secs /dev/bus/usb/001/011 test 6, 2.594610 secs /dev/bus/usb/001/011 test 7, 2.905459 secs /dev/bus/usb/001/011 test 8, 2.795193 secs /dev/bus/usb/001/011 test 9, 8.372651 secs /dev/bus/usb/001/011 test 10, 6.919731 secs /dev/bus/usb/001/011 test 11, 16.372687 secs /dev/bus/usb/001/011 test 12, 16.375233 secs /dev/bus/usb/001/011 test 13, 2.977457 secs /dev/bus/usb/001/011 test 14 --> 22 (Invalid argument) /dev/bus/usb/001/011 test 17, 0.148826 secs /dev/bus/usb/001/011 test 18, 0.068718 secs /dev/bus/usb/001/011 test 19, 0.125992 secs /dev/bus/usb/001/011 test 20, 0.127477 secs /dev/bus/usb/001/011 test 21 --> 22 (Invalid argument) /dev/bus/usb/001/011 test 24, 4.133763 secs /dev/bus/usb/001/011 test 27, 2.140066 secs /dev/bus/usb/001/011 test 28, 2.120713 secs /dev/bus/usb/001/011 test 29, 0.507762 secs Signed-off-by: Faizel K B <faizel.kb@dicortech.com> Link: https://lore.kernel.org/r/20210902114444.15106-1-faizel.kb@dicortech.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-05-07treewide: remove editor modelines and cruftMasahiro Yamada
The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

2020-06-27usbip: tools: add in man page how to load the client's moduleAntonio Borneo
While the man page usbipd.8 already informs the user on which kernel module has to be used on server side, the man page usbip.8 does not provide any equivalent information on client side. Also, it could be hard for a newbie to identify the proper usbip client kernel module, due to the name "vhci-hcd" that has no immediate assonance with usbip. Add in usbip.8 the command to add the module vhci-hcd, similarly as it's already present in usbipd.8 for usbip-host. While there, rephrase the description of the command "usbip list --remote=server".

2018-07-17tools: usb: ffs-test: Fix build on big endian systemsPeter Senna Tschudin
The tools/usb/ffs-test.c file defines cpu_to_le16/32 by using the C library htole16/32 function calls. However, cpu_to_le16/32 are used when initializing structures, i.e in a context where a function call is not allowed. It works fine on little endian systems because htole16/32 are defined by the C library as no-ops. But on big-endian systems, they are actually doing something, which might involve calling a function, causing build failures, such as: ffs-test.c:48:25: error: initializer element is not constant #define cpu_to_le32(x) htole32(x) ^~~~~~~ ffs-test.c:128:12: note: in expansion of macro ‘cpu_to_le32’ .magic = cpu_to_le32(FUNCTIONFS_DESCRIPTORS_MAGIC_V2), ^~~~~~~~~~~ To solve this, we code cpu_to_le16/32 in a way that allows them to be used when initializing structures.

Changed usbip_network, usbip_attach, usbip_list, and usbipd to use and propagate the new error codes in server reply messages. usbip_net_recv_op_common() is changed to take a pointer to status return the status returned in the op_common.status to callers. usbip_attach and usbip_list use the common interface to print error messages to indicate why the request failed. With this change the messages say why a request failed: - when a client requests a device that is already exported: usbip attach -r server_name -b 3-10.2 usbip: error: Attach Request for 3-10.2 failed - Device busy (exported) - when a client requests a device that isn't exportable, usbip attach -r server_name -b 3-10.4 usbip: error: Attach Request for 3-10.4 failed - Device not found Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2018-02-21tools: fix cross-compile var clobberingMartin Kelly
Currently a number of Makefiles break when used with toolchains that pass extra flags in CC and other cross-compile related variables (such as --sysroot). Thus we get this error when we use a toolchain that puts --sysroot in the CC var: ~/src/linux/tools$ make iio [snip] iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory #include <unistd.h> ^~~~~~~~~~ This occurs because we clobber several env vars related to cross-compiling with lines like this: CC = $(CROSS_COMPILE)gcc Although this will point to a valid cross-compiler, we lose any extra flags that might exist in the CC variable, which can break toolchains that rely on them (for example, those that use --sysroot). This easily shows up using a Yocto SDK: $ . [snip]/sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi $ echo $CC arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8 --sysroot=[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi $ echo $CROSS_COMPILE arm-poky-linux-gnueabi- $ echo ${CROSS_COMPILE}gcc krm-poky-linux-gnueabi-gcc Although arm-poky-linux-gnueabi-gcc is a cross-compiler, we've lost the --sysroot and other flags that enable us to find the right libraries to link against, so we can't find unistd.h and other libraries and headers. Normally with the --sysroot flag we would find unistd.h in the sdk directory in the sysroot: $ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h' [snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.h The perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is not already set, and it compiles correctly with the above toolchain. So, generalize the logic that perf uses in the common Makefile and remove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile. Note that this patch does not fix cross-compile for all the tools (some have other bugs), but it does fix it for all except usb and acpi, which still have other unrelated issues. I tested both with and without the patch on native and cross-build and there appear to be no regressions.

2017-12-08usbip: prevent vhci_hcd driver from leaking a socket pointer addressShuah Khan
When a client has a USB device attached over IP, the vhci_hcd driver is locally leaking a socket pointer address via the /sys/devices/platform/vhci_hcd/status file (world-readable) and in debug output when "usbip --debug port" is run. Fix it to not leak. The socket pointer address is not used at the moment and it was made visible as a convenient way to find IP address from socket pointer address by looking up /proc/net/{tcp,tcp6}. As this opens a security hole, the fix replaces socket pointer address with sockfd.

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