2019-01-25iwlwifi: fix spelling mistake "registrating" -> "registering"Colin Ian King1-1/+1
Trivial fix to spelling mistake in IWL_ERR error message Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2018-12-14iwlwifi: move iwl_nvm_check_version() into dvmLuca Coelho1-0/+17
This function is only half-used by mvm (i.e. only the nvm_version part matters, since the calibration version is irrelevant), so it's pointless to export it from iwlwifi. If mvm uses this function, it has the additional complexity of setting the calib version to a bogus value on all cfg structs. To avoid this, move the function to dvm and make a simple comparison of the nvm_version in mvm instead. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2018-09-28iwlwifi: remove ucode error tracepointJohannes Berg1-1/+1
Alexei's patch, assumed that all versions of "struct iwl_error_event_table" are the same, but there are really different versions in different files. Rather than trying to fix this, or splitting the tracepoint, or anything of the sort, just remove it entirely - turns out that nobody really uses it.

2018-08-31iwlwifi: remove all occurrences of the FSF address paragraphLuca Coelho24-105/+0
The Free Software Foundation address is superfluous and causes checkpatch to issue a warning when present. Remove all paragraphs with FSF's address to prevent that. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2018-04-20iwlwifi: remove upper case letters in sku_capa_band_*_enableLuca Coelho1-4/+4
The sku_capa_band_24GHz_enable and sku_capa_band_52GHz_enable symbols cause checkpatch to complain whenever we use them. To prevent this, convert them to all lower case. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-03-31 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add raw BPF tracepoint API in order to have a BPF program type that can access kernel internal arguments of the tracepoints in their raw form similar to kprobes based BPF programs. This infrastructure also adds a new BPF_RAW_TRACEPOINT_OPEN command to BPF syscall which returns an anon-inode backed fd for the tracepoint object that allows for automatic detach of the BPF program resp. unregistering of the tracepoint probe on fd release, from Alexei. 2) Add new BPF cgroup hooks at bind() and connect() entry in order to allow BPF programs to reject, inspect or modify user space passed struct sockaddr, and as well a hook at post bind time once the port has been allocated. They are used in FB's container management engine for implementing policy, replacing fragile LD_PRELOAD wrapper intercepting bind() and connect() calls that only works in limited scenarios like glibc based apps but not for other runtimes in containerized applications, from Andrey. 3) BPF_F_INGRESS flag support has been added to sockmap programs for their redirect helper call bringing it in line with cls_bpf based programs. Support is added for both variants of sockmap programs, meaning for tx ULP hooks as well as recv skb hooks, from John. 4) Various improvements on BPF side for the nfp driver, besides others this work adds BPF map update and delete helper call support from the datapath, JITing of 32 and 64 bit XADD instructions as well as offload support of bpf_get_prandom_u32() call. Initial implementation of nfp packet cache has been tackled that optimizes memory access (see merge commit for further details), from Jakub and Jiong. 5) Removal of struct bpf_verifier_env argument from the print_bpf_insn() API has been done in order to prepare to use print_bpf_insn() soon out of perf tool directly. This makes the print_bpf_insn() API more generic and pushes the env into private data. bpftool is adjusted as well with the print_bpf_insn() argument removal, from Jiri. 6) Couple of cleanups and prep work for the upcoming BTF (BPF Type Format). The latter will reuse the current BPF verifier log as well, thus bpf_verifier_log() is further generalized, from Martin. 7) For bpf_getsockopt() and bpf_setsockopt() helpers, IPv4 IP_TOS read and write support has been added in similar fashion to existing IPv6 IPV6_TCLASS socket option we already have, from Nikita. 8) Fixes in recent sockmap scatterlist API usage, which did not use sg_init_table() for initialization thus triggering a BUG_ON() in scatterlist API when CONFIG_DEBUG_SG was enabled. This adds and uses a small helper sg_init_marker() to properly handle the affected cases, from Prashant. 9) Let the BPF core follow IDR code convention and therefore use the idr_preload() and idr_preload_end() helpers, which would also help idr_alloc_cyclic() under GFP_ATOMIC to better succeed under memory pressure, from Shaohua. 10) Last but not least, a spelling fix in an error message for the BPF cookie UID helper under BPF sample code, from Colin. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-28net/wireless/iwlwifi: fix iwlwifi_dev_ucode_error tracepointAlexei Starovoitov1-6/+1
fix iwlwifi_dev_ucode_error tracepoint to pass pointer to a table instead of all 17 arguments by value. dvm/main.c and mvm/utils.c have 'struct iwl_error_event_table' defined with very similar yet subtly different fields and offsets. tracepoint is still common and using definition of 'struct iwl_error_event_table' from dvm/commands.h while copying fields. Long term this tracepoint probably should be split into two. Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

This converts all remaining setup_timer() calls that use a nested field to reach a struct timer_list.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook1-8/+6
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;

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.

2017-07-21iwlwifi: dvm: prevent an out of bounds accessEmmanuel Grumbach1-1/+1
iwlagn_check_ratid_empty takes the tid as a parameter, but it doesn't check that it is not IWL_TID_NON_QOS. Since IWL_TID_NON_QOS = 8 and iwl_priv::tid_data is an array with 8 entries, accessing iwl_priv::tid_data[IWL_TID_NON_QOS] is a bad idea. This happened in iwlagn_rx_reply_tx. Since iwlagn_check_ratid_empty is relevant only to check whether we can open A-MPDU, this flow is irrelevant if tid is IWL_TID_NON_QOS. Call iwlagn_check_ratid_empty only inside the if (tid != IWL_TID_NON_QOS) a few lines earlier in the function.

Next patch will add a wait for single TX queue which is needed for gen2 to be scalable for 512.

2017-03-06wireless: Set NL80211_EXT_FEATURE_CQM_RSSI_LIST in multiple driversAndrew Zaborowski1-0/+2
Set the NL80211_EXT_FEATURE_CQM_RSSI_LIST wiphy extended feature wholesale in all mac80211-based drivers that do not set the IEEE80211_VIF_BEACON_FILTER flags on their interfaces. mac80211 will be processing supplied RSSI values in ieee80211_rx_mgmt_beacon and will detect when the thresholds set by ieee80211_set_cqm_rssi_range_config are crossed. Remaining (few) drivers need code to enable the firmware to monitor the thresholds. This is mostly only compile-tested.

In https://bugzilla.kernel.org/show_bug.cgi?id=177341 Bob reported a UBSAN WARNING on rs.c. Undefined behaviour in drivers/net/wireless/intel/iwlwifi/dvm/rs.c:746:18 This because i = index - 1; for (mask = (1 << i); i >= 0; i--, mask >>= 1) is unsafe: i could be negative and hence we can call << on a negative value. This bug doesn't have any real impact since the condition of the for loop will prevent any usage of mask.

2016-07-06iwlwifi: decouple PCIe transport from mac80211Johannes Berg1-0/+2
The PCIe transport needs to store two pointers in each TX SKB, and currently assumes mac80211's ieee80211_tx_info is present in the CB to do that. In order to remove that assumption, have the opmodes pass in the offset to where the pointers can be stored in the CB and use the offset in the PCIe code. To make the disentanglement complete, remove mac80211.h includes from everywhere in the generic iwlwifi code. This required adding an include of cfg80211.h in one place.

2016-07-01iwlwifi: advertise maximal MPDU length when Rx MQ is supportedEmmanuel Grumbach1-0/+1
The new hardware that supports multiple queue also de-aggregates A-MSDUs. This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K. Setting the amsdu_size module parameter to 4K will limit the A-MSDU on 9000 as well.

Use alloc_ordered_workqueue() to allocate the workqueue instead of create_singlethread_workqueue() since the latter is deprecated and is scheduled for removal. There are work items doing related operations that shouldn't be swapped when queued in a certain order hence preserve the strict execution ordering of a single threaded (ST) workqueue by switching to alloc_ordered_workqueue(). WQ_MEM_RECLAIM flag is not needed since the worker is not depended during memory reclaim.
