[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.

Sorry, I thought it was dependant on the previous patches, given that the first time I tried to apply it, it failed. Omer, can you just resend this single patch to me and I will be glad to apply it to the staging tree, if it really is stand-alone. thanks, greg k-h ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

Hehe :) But I don't see why this patch 5 should go either to mac80211 or wireless-drivers trees as there's no dependency or anything like that, AFAIK it's just cleanup. So it would simplest to get this patch 5 to staging tree, less conflicts that way. Patches 1 and 2 of course go to mac80211 tree and patch 4 goes to wireless-drivers. -- Kalle Valo ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

[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.
