Qi Tao (2): uadk_engine: add secure compilation option
configure.ac | 1 + src/Makefile.am | 2 ++ 2 files changed, 3 insertions(+)
Add PIE, PIC, BIND_NOW, SP, NO Rpath/RunPath, FS, Ftrapv and Strip compilation option.
PIC（-fPIC): Generate position-Independent-Code and andomly load dynamic libraries. PIE(-fPIE -pie): Generate location-independent executables,which reduces the probability of fixed address attacks and buffer overflow attacks. BIND_NOW(-Wl,-z,relro,-z,now): GOT table redirects all read-only,which defends against ret2plt attacks. SP(-fstack-protector-strong/all): Determine whether an overflow attack occurs. Strip(-Wl,-s): Deleting symbol tables defends against hacker attacks and reduces the file size. FS(-D_FORTIFY_SOURCE=2 -O2): Provides access checks for fixed-size buffers at compile time and at run time. Ftrapv(-ftrapv): Detects integer overflow. NO Rpath/RunPath(hardcode_into_libs=no): Eliminates dynamic library search paths, which defense against attacks by replacing dynamic libraries with the same name.
