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.

2017-07-17staging: vboxvideo: Add vboxvideo to drivers/stagingHans de Goede
This commit adds the vboxvideo drm/kms driver for the virtual graphics card used in Virtual Box virtual machines to drivers/staging. Why drivers/staging? This driver is already being patched into the kernel by several distros, thus it is good to get this driver upstream soon, so that work on the driver can be easily shared. At the same time we want to take our time to get this driver properly cleaned up (mainly converted to the new atomic modesetting APIs) before submitting it as a normal driver under drivers/gpu/drm, putting this driver in staging for now allows both. Note this driver has already been significantly cleaned up, when I started working on this the files under /usr/src/vboxguest/vboxvideo as installed by Virtual Box 5.1.18 Guest Additions had a total linecount of 52681 lines. The version in this commit has 4874 lines.

Code was present to handle the case where a CLOSE is sent immediately after an OPEN, i.e. before the OPENACK has been received, but this was incorrectly being used when an OPEN from a client using port 0 was rejected. (In the observed failure, the host was attempting to use the VCSM service, which isn't present in the 'cutdown' firmware. The failure was intermittent because sometimes the keepalive service would grab port 0.) This case can be distinguished because the client's remoteport will still be VCHIQ_PORT_FREE, and the srvstate will be OPENING. Either condition is sufficient to differentiate it from the special case described above. vchiq: Avoid high load when blocked and unkillable vchiq: Include SIGSTOP and SIGCONT in list of signals not-masked by vchiq to allow gdb to work vchiq_arm: Complete support for SYNCHRONOUS mode vchiq: Remove inline from suspend/resume vchiq: Allocation does not need to be atomic vchiq: Fix wrong condition check The log level is checked from within the log call.

The existence of this parameter guarantees that the kernel is capable, and the parameter will only be modified from the safe default if the loader is capable. 2) Flush/invalidate vmalloc'd memory, and invalidate after reads vchiq: fix NULL pointer dereference when closing driver The following code run as root will cause a null pointer dereference oops: int fd = open("/dev/vc-cma", O_RDONLY); if (fd < 0) err(1, "open failed"); (void)close(fd); [ 1704.877721] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 1704.877725] pgd = b899c000 [ 1704.877736] [00000000] *pgd=37fab831, *pte=00000000, *ppte=00000000 [ 1704.877748] Internal error: Oops: 817 [#1] PREEMPT SMP ARM [ 1704.877765] Modules linked in: evdev i2c_bcm2708 uio_pdrv_genirq uio [ 1704.877774] CPU: 2 PID: 3656 Comm: stress-ng-fstat Not tainted 3.19.1-12-generic-bcm2709 #12-Ubuntu [ 1704.877777] Hardware name: BCM2709 [ 1704.877783] task: b8ab9b00 ti: b7e68000 task.ti: b7e68000 [ 1704.877798] PC is at __down_interruptible+0x50/0xec [ 1704.877806] LR is at down_interruptible+0x5c/0x68 [ 1704.877813] pc : [<80630ee8>] lr : [<800704b0>] psr: 60080093 sp : b7e69e50 ip : b7e69e88 fp : b7e69e84 [ 1704.877817] r10: b88123c8 r9 : 00000010 r8 : 00000001 [ 1704.877822] r7 : b8ab9b00 r6 : 7fffffff r5 : 80a1cc34 r4 : 80a1cc34 [ 1704.877826] r3 : b7e69e50 r2 : 00000000 r1 : 00000000 r0 : 80a1cc34 [ 1704.877833] Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user [ 1704.877838] Control: 10c5387d Table: 3899c06a DAC: 00000015 [ 1704.877843] Process do-oops (pid: 3656, stack limit = 0xb7e68238) [ 1704.877848] Stack: (0xb7e69e50 to 0xb7e6a000) [ 1704.877856] 9e40: 80a1cc3c 00000000 00000010 b88123c8 [ 1704.877865] 9e60: b7e69e84 80a1cc34 fff9fee9 ffffffff b7e68000 00000009 b7e69ea4 b7e69e88 [ 1704.877874] 9e80: 800704b0 80630ea4 fff9fee9 60080013 80a1cc28 fff9fee9 b7e69edc b7e69ea8 [ 1704.877884] 9ea0: 8040f558 80070460 fff9fee9 ffffffff 00000000 00000000 00000009 80a1cb7c [ 1704.877893] 9ec0: 00000000 80a1cb7c 00000000 00000010 b7e69ef4 b7e69ee0 803e1ba4 8040f514 [ 1704.877902] 9ee0: 00000e48 80a1cb7c b7e69f14 b7e69ef8 803e1c9c 803e1b74 b88123c0 b92acb18 [ 1704.877911] 9f00: b8812790 b8d815d8 b7e69f24 b7e69f18 803e2250 803e1bc8 b7e69f5c b7e69f28 [ 1704.877921] 9f20: 80167bac 803e222c 00000000 00000000 b7e69f54 b8ab9ffc 00000000 8098c794 [ 1704.877930] 9f40: b8ab9b00 8000efc4 b7e68000 00000000 b7e69f6c b7e69f60 80167d6c 80167b28 [ 1704.877939] 9f60: b7e69f8c b7e69f70 80047d38 80167d60 b7e68000 b7e68010 8000efc4 b7e69fb0 [ 1704.877949] 9f80: b7e69fac b7e69f90 80012820 80047c84 01155490 011549a8 00000001 00000006 [ 1704.877957] 9fa0: 00000000 b7e69fb0 8000ee5c 80012790 00000000 353d8c0f 7efc4308 00000000 [ 1704.877966] 9fc0: 01155490 011549a8 00000001 00000006 00000000 00000000 76cf3ba0 00000003 [ 1704.877975] 9fe0: 00000000 7efc42e4 0002272f 76e2ed66 60080030 00000003 00000000 00000000 [ 1704.877998] [<80630ee8>] (__down_interruptible) from [<800704b0>] (down_interruptible+0x5c/0x68) [ 1704.878015] [<800704b0>] (down_interruptible) from [<8040f558>] (vchiu_queue_push+0x50/0xd8) [ 1704.878032] [<8040f558>] (vchiu_queue_push) from [<803e1ba4>] (send_worker_msg+0x3c/0x54) [ 1704.878045] [<803e1ba4>] (send_worker_msg) from [<803e1c9c>] (vc_cma_set_reserve+0xe0/0x1c4) [ 1704.878057] [<803e1c9c>] (vc_cma_set_reserve) from [<803e2250>] (vc_cma_release+0x30/0x38) [ 1704.878069] [<803e2250>] (vc_cma_release) from [<80167bac>] (__fput+0x90/0x1e0) [ 1704.878082] [<80167bac>] (__fput) from [<80167d6c>] (____fput+0x18/0x1c) [ 1704.878094] [<80167d6c>] (____fput) from [<80047d38>] (task_work_run+0xc0/0xf8) [ 1704.878109] [<80047d38>] (task_work_run) from [<80012820>] (do_work_pending+0x9c/0xc4) [ 1704.878123] [<80012820>] (do_work_pending) from [<8000ee5c>] (work_pending+0xc/0x20) [ 1704.878133] Code: e50b1034 e3a01000 e50b2030 e580300c (e5823000) ..the fix is to ensure that we have actually initialized the queue before we attempt to push any items onto it.

The icn, act2000 and pcbit drivers are all for very old hardware, and it is highly unlikely that anyone is actually still using them on modern kernels, if at all. All three drivers apparently are for hardware that predates PCI being the common connector, as they are ISA-only and active PCI ISDN cards were widely available in the 1990s. Looking through the git logs, it I cannot find any indication of a patch to any of these drivers that has been tested on real hardware, only cleanups or global API changes.

2016-02-07staging: drop kbuild workaround dummy module from top dirPaul Gortmaker
This is essentially a revert of 86f69fe9c069dd8608d238581eea259caa1dfc99 ("Staging: workaround build system bug"), but to call it a revert would imply it was wrong -- rather it seems more like it is just no longer required anymore. It doesn't list the full details of the failing use case, but the most obvious would appear to be a "make allnoconfig" that subsequently had set just CONFIG_STAGING=y in the .config file, to give: paul@builder:~/git/linux-head$ grep STAGING ../staging-allno/.config CONFIG_STAGING=y # CONFIG_STAGING_MEDIA is not set # CONFIG_STAGING_BOARD is not set paul@builder:~/git/linux-head$ After building this .config (on ARM, just to be different), we see that built-in.o is created, and the final vmlinux links OK: paul@builder:~/git/linux-head$ ls -l ../staging-allno/drivers/staging/built-in.o -rw-rw-r-- 1 paul paul 257 Nov 16 18:06 ../staging-allno/drivers/staging/built-in.o paul@builder:~/git/linux-head$ file ../staging-allno/drivers/staging/built-in.o ../staging-allno/drivers/staging/built-in.o: ELF 32-bit LSB relocatable, ARM, version 1, not stripped paul@builder:~/git/linux-head$ nm ../staging-allno/drivers/staging/built-in.o nm: ../staging-allno/drivers/staging/built-in.o: no symbols paul@builder:~/git/linux-head$ ls -l ../staging-allno/vmlinux -rwxrwxr-x 1 paul paul 1236326 Nov 16 18:07 ../staging-allno/vmlinux paul@builder:~/git/linux-head$ I also tested an "allmodconfig" and did not see any problems there either.

I've put them through a decent amount of testing prior to sending the pull request due to that. There are still a few fixups that I know are coming, but I wanted to go ahead and get the big, sizable chunk into your hands sooner rather than waiting for those last few fixups. Of note is the fact that this creates what is intended to be a temporary area in the drivers/staging tree specifically for some cleanups and additions that are coming for the RDMA stack. We deprecated two drivers (ipath and amso1100) and are waiting to hear back if we can deprecate another one (ehca). We also put Intel's new hfi1 driver into this area because it needs to be refactored and a transfer library created out of the factored out code, and then it and the qib driver and the soft-roce driver should all be modified to use that library. I expect drivers/staging/rdma to be around for three or four kernel releases and then to go away as all of the work is completed and final deletions of deprecated drivers are done. Summary of changes for 4.3: - Create drivers/staging/rdma - Move amso1100 driver to staging/rdma and schedule for deletion - Move ipath driver to staging/rdma and schedule for deletion - Add hfi1 driver to staging/rdma and set TODO for move to regular tree - Initial support for namespaces to be used on RDMA devices - Add RoCE GID table handling to the RDMA core caching code - Infrastructure to support handling of devices with differing read and write scatter gather capabilities - Various iSER updates - Kill off unsafe usage of global mr registrations - Update SRP driver - Misc mlx4 driver updates - Support for the mr_alloc verb - Support for a netlink interface between kernel and user space cache daemon to speed path record queries and route resolution - Ininitial support for safe hot removal of verbs devices" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (136 commits) IB/ipoib: Suppress warning for send only join failures IB/ipoib: Clean up send-only multicast joins IB/srp: Fix possible protection fault IB/core: Move SM class defines from ib_mad.h to ib_smi.h IB/core: Remove unnecessary defines from ib_mad.h IB/hfi1: Add PSM2 user space header to header_install IB/hfi1: Add CSRs for CONFIG_SDMA_VERBOSITY mlx5: Fix incorrect wc pkey_index assignment for GSI messages IB/mlx5: avoid destroying a NULL mr in reg_user_mr error flow IB/uverbs: reject invalid or unknown opcodes IB/cxgb4: Fix if statement in pick_local_ip6adddrs IB/sa: Fix rdma netlink message flags IB/ucma: HW Device hot-removal support IB/mlx4_ib: Disassociate support IB/uverbs: Enable device removal when there are active user space applications IB/uverbs: Explicitly pass ib_dev to uverbs commands IB/uverbs: Fix race between ib_uverbs_open and remove_one IB/uverbs: Fix reference counting usage of event files IB/core: Make ib_dealloc_pd return void IB/srp: Create an insecure all physical rkey only if needed ...

Create the rdma directory in the staging area for use as we deprecate some older drivers and as we bring in some new drivers that are in need of work. Update the MAINTAINERS file so that updates to these files go to linux-rdma@vger.kernel.org. Expected lifespan of this directory is three releases for any deprecated drivers moved here and an unknown, but theoretically bounded amount of time for the new drivers as a new core RDMA transfer library needs to be written and the drivers modified to use it in order for them to move out of this directory.

2015-07-24Staging: most: add MOST driver's core moduleChristian Gromm
This patch adds the core module of the MOST driver to the kernel's driver staging area. This module is part of the MOST driver and handles the configuration interface in sysfs, the buffer management and the data routing. MOST defines the protocol, hardware and software layers necessary to allow for the efficient and low-cost transport of control, real-time and packet data using a single medium (physical layer). Media currently in use are fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST also supports various speed grades up to 150 Mbps. For more information on MOST, visit the MOST Cooperation website: www.mostcooperation.com. Cars continue to evolve into sophisticated consumer electronics platforms, increasing the demand for reliable and simple solutions to support audio, video and data communications. MOST can be used to connect multiple consumer devices via optical or electrical physical layers directly to one another or in a network configuration. As a synchronous network, MOST provides excellent Quality of Service and seamless connectivity for audio/video streaming. Therefore, the driver perfectly fits to the mission of Automotive Grade Linux to create open source software solutions for automotive applications. The driver consists basically of three layers. The hardware layer, the core layer and the application layer. The core layer consists of the core module only. This module handles the communication flow through all three layers, the configuration of the driver, the configuration interface representation in sysfs, and the buffer management. For each of the other two layers a selection of modules is provided. These modules can arbitrarily be combined to meet the needs of the desired system architecture. A module of the hardware layer is referred to as an HDM (hardware dependent module). Each module of this layer handles exactly one of the peripheral interfaces of a network interface controller (e.g. USB, MediaLB, I2C). A module of the application layer is referred to as an AIM (application interfacing module). The modules of this layer give access to MOST via one the following ways: character devices, ALSA, Networking or V4L2. To physically access MOST, an Intelligent Network Interface Controller (INIC) is needed.

Lots of little things in here, adding up to lots of overall cleanups. The IIO driver updates are also in here as they cross the staging tree boundry a lot. I2O has moved into staging as well, as a plan to drop it from the tree eventually as that's a dead subsystem. All of this has been in linux-next with no reported issues for a while" * tag 'staging-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (740 commits) staging: lustre: lustre: libcfs: define symbols as static staging: rtl8712: Do coding style cleanup staging: lustre: make obd_updatemax_lock static staging: rtl8188eu: core: switch with redundant cases staging: rtl8188eu: odm: conditional setting with no effect staging: rtl8188eu: odm: condition with no effect staging: ft1000: fix braces warning staging: sm7xxfb: fix remaining CamelCase staging: sm7xxfb: fix CamelCase staging: rtl8723au: multiple condition with no effect - if identical to else staging: sm7xxfb: make smtc_scr_info static staging/lustre/mdc: Initialize req in mdc_enqueue for !it case staging/lustre/clio: Do not allow group locks with gid 0 staging/lustre/llite: don't add to page cache upon failure staging/lustre/llite: Add exception entry check after radix_tree staging/lustre/libcfs: protect kkuc_groups from write access staging/lustre/fld: refer to MDT0 for fld lookup in some cases staging/lustre/llite: Solve a race to access lli_has_smd in read case staging/lustre/ptlrpc: hold rq_lock when modify rq_flags staging/lustre/lnet: portal spreading rotor should be unsigned ...
2015-02-03staging: cptm1217: blow it all awayAlan Cox
We have a drivers/input layer for Synaptics products and nothing should now be using the staging driver. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-02-03i2o: move to stagingAlan Cox
The I2O layer deals with a technology that to say the least didn't catch on in the market. The only relevant products are some of the AMI MegaRAID - which supported I2O and its native mode (The native mode is faster and runs on Linux), an obscure crypto ethernet card that's now so many years out of date nobody would use it, the old DPT controllers, which speak their own dialect and have their own driver - and ermm.. thats about it. We also know the code isn't in good shape as recently a patch was proposed and queried as buggy, which in turn showed the existing code was broken already by prior "clean up" and nobody had noticed that either. It's coding style robot code nothing more. Like some forgotten corridor cleaned relentlessly by a lost Roomba but where no user has trodden in years. Move it to staging and then to /dev/null. The headers remain as they are shared with dpt_i2o. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
