2018-03-13net/wireless: fix spaces and grammar copy/paste in vendor Kconfig help textRandy Dunlap1-2/+2
Lots of the wireless driver vendor Kconfig symol help text says "questions about cards." (2 spaces between "about" and "cards") Besides dropping one of those spaces, it also needs some other word inserted there. Instead of putting each vendor's name there, I chose to say "these" cards in all of the Kconfig help text.

2018-02-27qtnfmac: fix releasing Tx/Rx data buffersSergey Matyukevich1-12/+18
Add missing PCI unmap for Tx buffers and release all buffers explicitly. Managed release using devm_add_action is not suitable for qtnfmac Tx/Rx data buffers. The reason is in ordering and dependencies: buffers should be released after transmission is stopped but before PCI device resources and DMA allocations are released.

2018-01-24qtnfmac: do not use bus mutex for events processingIgor Mitsyanko1-2/+2
Events processing requires locking of bus mutex, which is also used by cfg80211 layer before calling several of cfg80211 callbacks. Since all cfg80211 callbacks in qtnfmac driver also lock bus mutex, this potentially may lead to a deadlock. Do not use bus lock for event processing. Use RTNL lock instead to serialize events and commands processing threads. Signed-off-by: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-01-24qtnfmac: fix STA disconnect procedureSergey Matyukevich1-1/+0
STA does not reconnect to the same AP after disconnect. The reason is that STA is marked as disconnected in cfg80211 disconnect callback. This is too early since in this case qtnfmac event handler skips cfg80211_disconnected call when processing disconnect event from the card. As a result, wdev is left in an inconsistent state.

2018-01-24qtnfmac: validate interface combinations on changesSergey Matyukevich1-0/+50
Validate new interface combinations using wireless core checks when new interface is added or when the type of existing interface is modified. This is performed to make sure that new interface combination is supported by hardware. As a result, invalid interface combinations are rejected early, rather than passed to hardware with sometimes unpredictable results.

2018-01-24qtnfmac: modify supported interface combinationsSergey Matyukevich5-76/+115
Update existing code handling configuration of supported interface combinations. Current implementation is not complete since it does not report multiple interface combinations which are incompatible with each other. Instead current implementation packs all the supported combinations into single entry. In fact currently qsr10g wireless card supports the following two distinct interface combinations: 1. STA/repeater: 1 STA and/or 1 AP { { .max = 1, .types = NL80211_IFTYPE_AP}, { .max = 1, .types = NL80211_IFTYPE_STA}, } 2. AP/mBSS { { .max = 8, .types = NL80211_IFTYPE_AP}, } The list of supported configuration is reported by firmware during wireless card bring-up. Communication protocol between firmware and host has been updated accordingly in order to accommodate passing multiple interface combination entries.

2017-11-21treewide: Remove TIMER_FUNC_TYPE and TIMER_DATA_TYPE castsKees Cook1-1/+1
With all callbacks converted, and the timer callback prototype switched over, the TIMER_FUNC_TYPE cast is no longer needed, so remove it. Conversion was done with the following scripts: perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \ $(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u) perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \ $(git grep TIMER_DATA_TYPE | cut -d: -f1 | sort -u) The now unused macros are also dropped from include/linux/timer.h.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook1-1/+1
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

Current logic artificially divides "start AP" procedure into three stages: - generic interface configuration (security, channel etc) - IE's processing - enable AP mode on interface This separation would not allow to do a proper device configuration as first stage needs to use information from IEs that are processed on a second stage. Which means first and second stages have to be meged. In that case there is no point anymore to keep third stage either, so merge all three into a single command.

HT/VHT capabilities must be reported per each band supported by a radio, not for all bands on a radio. Furthermore, driver better not assume any capabilities and just use whetever is reported by device itself. To support this, convert "get channels" command into "get band info" command. Difference is that it may also carry HT/VHT capabilities along with channels information. While at it, also add "num_bitrates" field to "get band info" command, for future use.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
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.

2017-10-30qtnfmac: modify full Tx queue recoverySergey Matyukevich4-5/+37
Current recovery approach is to wake s/w Tx queues for skb->dev netdevice. However this approach doesn't cover the case when h/w queue is full of packets from a single wireless interface. Suppose xmit attempt from the second wireless interface fails due to failed reclaim. Then the second interface will not have a chance to recover even if subsequent reclaims succeed. Possible solution is to attempt to wake all the s/w queues belonging to driver interfaces.
