2021-04-09staging: rtl8712: remove struct rtl_ieee80211_ht_cap and ieee80211_ht_addt_infoChristophe JAILLET1-3/+3
struct 'ieee80211_ht_addt_info' is unused and can be removed. struct 'rtl_ieee80211_ht_cap' can be replaced by 'ieee80211_ht_cap' defined in <linux/ieee80211.h> which has the same layout.

2021-03-10staging: rtl8712: unterminated string leads to read overflowDan Carpenter1-1/+1
The memdup_user() function does not necessarily return a NUL terminated string so this can lead to a read overflow. Switch from memdup_user() to strndup_user() to fix this bug.

2021-02-04staging: rtl8712: Switch from strlcpy to strscpyKumar Kartikeya Dwivedi1-1/+1
strlcpy is marked as deprecated in Documentation/process/deprecated.rst, and there is no functional difference when the caller expects truncation (when not checking the return value). strscpy is relatively better as it also avoids scanning the whole source string.

Non obvious changes: - struct ieee80211_ht_cap is different enough that I preferred to keep (and rename) it for now. - mcs_rate in translate_scan was not read after being set, so I deleted that part rather than using the renamed struct - WLAN_CAPABILITY_BSS is replaced with WLAN_CAPABILITY_ESS which is the corresponding one with same value Signed-off-by: Pascal Terjan <pterjan@google.com> Link: https://lore.kernel.org/r/20200609194848.166130-1-pterjan@google.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-02-20staging: rtl8712: reduce stack usageArnd Bergmann1-1/+1
The "translate_scan" function in rtl8712 uses a lot of stack, and gets inlined into its single caller, r8711_wx_get_scan, which in some configurations now blows the 1024 byte stack warning limit: drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'r8711_wx_get_scan': drivers/staging/rtl8712/rtl871x_ioctl_linux.c:1227:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] This somewhat reduces the stack usage by moving the translate_scan function out of line with the noinline_for_stack annotation. It might be possible to modify translate_scan() a little further to reduce the stack usage, but with this patch, we can build without the warning, the the call chain to get here is rather predictable (sys_ioctl->vfs_ioctl->sock_ioctl->dev_ioctl->wext_ioctl-> r8711_wx_get_scan).

->KeyMaterial is declared as a 16 byte array, but we only ever allocate either 5 or 13 bytes of it. The problem is that we memset() all 16 bytes to zero so we're memsetting past the end of the allocated memory. I fixed this in slightly lazy way, by just allocating 16 bytes. This works but there is a lot more cleanup you could do to this code if you wanted. Which is why this code is in staging.
