[PATCH v3 5/5] staging: use BIT_ULL for NL80211_STA_INFO_* attribute types
The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).
Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.
This commit cleans up all usages of BIT macro with the above field
in cfg80211 by changing it to BIT_ULL instead.

[PATCH v3 0/5] use BIT_ULL for NL80211_STA_INFO_* attribute types
The BIT macro uses unsigned long which some architectures handle as 32 bit and therefore might cause macro's shift to overflow when used on a value equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards). Since 'filled' member in station_info changed to u64, BIT_ULL macro should be used with all NL80211_STA_INFO_* attribute types instead of BIT to prevent future possible bugs when one will use BIT macro for higher attributes by mistake. Note: The following patch series only does some code clean up. The previous versions mentioned a bug fix but it appears as a mix up with some local changes because NL80211_STA_INFO_TID_STATS value actually equals 31. Changes in v3: - Better phrasing commit messages due to the above note - Align patches to latest mac80211-next Omer Efrat (5): cfg80211: use BIT_ULL for NL80211_STA_INFO_* attribute types mac80211: use BIT_ULL for NL80211_STA_INFO_* attribute types batman-adv: use BIT_ULL for NL80211_STA_INFO_* attribute types wireless-drivers: use BIT_ULL for NL80211_STA_INFO_ attribute types staging: use BIT_ULL for NL80211_STA_INFO_* attribute types drivers/net/wireless/ath/ath10k/mac.c | 4 +- drivers/net/wireless/ath/ath6kl/cfg80211.c | 14 ++-- drivers/net/wireless/ath/wil6210/cfg80211.c| 18 ++--- .../broadcom/brcm80211/brcmfmac/cfg80211.c | 40 +-- drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c | 6 +- drivers/net/wireless/marvell/libertas/cfg.c| 12 ++-- drivers/net/wireless/marvell/mwifiex/cfg80211.c| 14 ++-- drivers/net/wireless/quantenna/qtnfmac/commands.c | 32 - drivers/net/wireless/rndis_wlan.c | 4 +- drivers/net/wireless/ti/wlcore/main.c | 2 +- drivers/staging/rtl8723bs/os_dep/ioctl_cfg80211.c | 10 +-- drivers/staging/wilc1000/wilc_wfi_cfgoperations.c | 14 ++-- drivers/staging/wlan-ng/cfg80211.c | 4 +- net/batman-adv/bat_v_elp.c | 2 +- net/mac80211/ethtool.c | 6 +- net/mac80211/sta_info.c| 84 +++--- net/wireless/nl80211.c | 26 +++ net/wireless/wext-compat.c | 10 +-- 18 files changed, 151 insertions(+), 151 deletions(-) -- 2.7.4 ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with NL80211_STA_INFO_* attribute types instead of BIT.
The BIT macro uses unsigned long type which some architectures handle as 32bit
and this results in compilation warnings such as:
