Subject: data structure for NT_386_LTS note entry in coredump
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.
