Dear All This is Zin. Sorry about sent a mail with corporate header on yesterday. I had changed my e-mail address. I want to do taint analysis using DFSan on 32bit platform(armv7/intel 32bit). But DFSan does not support 32bit arch. So i'm preparing a patch for that. For 32bit, I have to set each address that is supported by the platform as variables. For define memory layout for 32bit arch, i refer to existed platform. I compared each variable value in Mapping struct for x86_64 in dfsan_platform.h with https://www.kernel.org/doc/Documentation/x86/x86_64/mm.txt file. According to kernel.org, the user area is 0x0000000000000000 to 0x00007fffffffffff. However, kAppAddr starts at 0x0000700000008000 in dfsan_platform.h. So i am confused by the difference between kernel.org and dfsan_platform.h. Is there my missing point? Please let me know what should i do to define memory layout. and which information helps me.
