Arnd Bergmann 54d11736ec platform/x86: dell-smbios: fix string overflow ... The new sysfs code overwrites two fixed-length character arrays that are each one byte shorter than they need to be, to hold the trailing \0: drivers/platform/x86/dell-smbios.c: In function 'build_tokens_sysfs': drivers/platform/x86/dell-smbios.c:494:42: error: 'sprintf' writing a terminating nul past the end of the destination [-Werror=format-overflow=] sprintf(buffer_location, "%04x_location", drivers/platform/x86/dell-smbios.c:494:3: note: 'sprintf' output 14 bytes into a destination of size 13 drivers/platform/x86/dell-smbios.c:506:36: error: 'sprintf' writing a terminating nul past the end of the destination [-Werror=format-overflow=] sprintf(buffer_value, "%04x_value", drivers/platform/x86/dell-smbios.c:506:3: note: 'sprintf' output 11 bytes into a destination of size 10 This changes it to just use kasprintf(), which always gets it right. Discovered with gcc-7.1.1 with the following commit reverted: bd664f6b3e disable new gcc-7.1.1 warnings for now Fixes: 33b9ca1e53 ("platform/x86: dell-smbios: Add a sysfs interface for SMBIOS tokens") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Mario Limonciello <mario.limonciello@dell.com> [dvhart: add subject prefix and reproducer details for context] Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org>		2017-11-08 12:58:29 -08:00
