2024-02-08wifi: mac80211: simplify non-chanctx driversJohannes Berg
There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

2024-01-23wifi: iwlegacy: Use kcalloc() instead of kzalloc()Erick Archer
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function. Also, it is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter).

il4965_rs_fill_link_cmd() As a result of the execution of the inner while loop, the value of 'idx' can be equal to LINK_QUAL_MAX_RETRY_NUM. However, this is not checked after the loop and 'idx' is used to write the LINK_QUAL_MAX_RETRY_NUM size array 'lq_cmd->rs_table[idx]' below in the outer loop. The fix is to check the new value of 'idx' inside the nested loop, and break both loops if index equals the size. Checking it at the start is now pointless, so let's remove it.

2022-04-11mac80211: prepare sta handling for MLO supportSriram R
Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by: Sriram R <quic_srirrama@quicinc.com> Link: https://lore.kernel.org/r/1649086883-13246-1-git-send-email-quic_srirrama@quicinc.com [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2021-12-08iwlwifi: fix LED dependenciesArnd Bergmann
The dependencies for LED configuration are highly inconsistent and too complicated at the moment. One of the results is a randconfig failure I get very rarely when LEDS_CLASS is in a loadable module, but the wireless core is built-in: WARNING: unmet direct dependencies detected for MAC80211_LEDS Depends on [n]: NET [=y] && WIRELESS [=y] && MAC80211 [=y] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=MAC80211 [=y]) Selected by [m]: - IWLEGACY [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y] - IWLWIFI_LEDS [=y] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y] && IWLWIFI [=m] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=IWLWIFI [=m]) && (IWLMVM [=m] || IWLDVM [=m]) aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_register_led': led.c:(.text+0x60): undefined reference to `led_classdev_register_ext' aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_unregister_leds': led.c:(.text+0x200): undefined reference to `led_classdev_unregister' For iwlwifi, the dependency is wrong, since this config prevents the MAC80211_LEDS code from being part of a built-in MAC80211 driver. For iwlegacy, this is worse because the driver tries to force-enable the other subsystems, which is both a layering violation and a bug because it will still fail with MAC80211=y and IWLEGACY=m, leading to LEDS_CLASS being a module as well. The actual link failure in the ath5k driver is a result of MAC80211_LEDS being enabled but not usable. With the Kconfig logic fixed in the Intel drivers, the ath5k driver works as expected again.

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below.

2020-09-29net: ipw2x00,iwlegacy,iwlwifi: Remove in_interrupt() from debug macrosSebastian Andrzej Siewior
The usage of in_interrupt() in non-core code is phased out. The debugging macros in these drivers use in_interrupt() to print 'I' or 'U' depending on the return value of in_interrupt(). While 'U' is confusing at best and 'I' is not really describing the actual context (hard interupt, soft interrupt, bottom half disabled section) these debug macros originate from the pre ftrace kernel era and their value today is questionable. They probably should be removed completely. The macros weere added initially for ipw2100 and then spreaded when the driver was forked. Remove the in_interrupt() usage at least..

2020-07-16treewide: Remove uninitialized_var() usageKees Cook
Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space. No outstanding warnings were found building allmodconfig with GCC 9.3.0 for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64, alpha, and m68k.

2020-07-15iwlegacy: Check the return value of pcie_capability_read_*()Bolarinwa Olayemi Saheed
On failure pcie_capability_read_dword() sets it's last parameter, val to 0. However, with Patch 14/14, it is possible that val is set to ~0 on failure. This would introduce a bug because (x & x) == (~0 & x). This bug can be avoided without changing the function's behaviour if the return value of pcie_capability_read_dword is checked to confirm success. Check the return value of pcie_capability_read_dword() to ensure success.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
