Dear all, I have a question about data structure for NT_386_LTS note entry in coredump and where is the code to store this entry into coredump. When I analyzed coredump and corresponding assembly code, I found there is one memory addressing with gs. GS is a selector used by glibc. But its base address is stored in the kernel space which I don't know from "gdb executable core". But fortunately I find a note entry with type NT_386_LTS in my coredump. The following is the content of this note entry,

...

LINUX 48 386_TLS index: 6, base: 0xb7fd57c0, limit: 0x000fffff, flags: 0x00000051 index: 7, base: 0x00000000, limit: 0x00000000, flags: 0x00000028 index: 8, base: 0x00000000, limit: 0x00000000, flags: 0x00000028

Q1: Is there a data structure defined in header file like /usr/include/elf.h? Q2: Where is the code to store this entry into coredump? -- My best regards to you. No System Is Safe! Dongliang Mu
