2018-06-28staging: rtl8723bs: use mac_pton() in rtw_macaddr_cfg()Michael Straube2-29/+4
Use the mac_pton() helper to convert the mac address string. The functions key_char2num() and key_2char2num() are not used anywhere else and can be removed. This also has the benefit of validating the input since mac_pton() returns false if the string is not valid.

2018-06-28staging: rtl8723bs: refactor rtw_macaddr_cfg()Michael Straube1-15/+4
Using is_broadcast_ether_addr() and is_zero_ether_addr() instead of testing each byte of the mac[] array for 0xff and 0x00 shortens the code and improves readability. If np == NULL, of_get_property() returns NULL, hence the "np" check is not needed. Instead of a fixed default mac address use a random one to reduce the likelihood of mac address collision.

2018-06-28staging: rtsx: remove rtsx_trace() and related codeArnd Bergmann14-1344/+1
The driver has rather excessive amount of tracing code, which would be better done using ftrace. This is obviously not a main feature of the driver, and it should work just as well without it. Removing it saves over 1300 lines of code and likely makes the driver a bit faster by avoiding lots of calls into the timekeeping code. I came across this while cleaning up the last users of the deprecated getnstimeofday64() function, of which there is one in the now-removed get_current_time() function of the rtsx driver that was only used for tracing.

2018-06-28staging: use BIT_ULL for NL80211_STA_INFO_* attribute typesOmer Efrat3-14/+14
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.

2018-06-28staging: android: ashmem: Fix mmap size validationAlistair Strachan1-0/+6
The ashmem driver did not check that the size/offset of the vma passed to its .mmap() function was not larger than the ashmem object being mapped. This could cause mmap() to succeed, even though accessing parts of the mapping would later fail with a segmentation fault. Ensure an error is returned by the ashmem_mmap() function if the vma size is larger than the ashmem object size. This enables safer handling of the problem in userspace.
