Hi, all I build linux-3.12.6 uml with default configure. tar -jxf linux-3.12.6.tar.bz2 cd linux-3.12.6 make ARCH=um defconfig make ARCH=um linux
I'm confused about the exception table of the uml kernel. $ objdump --full-contents --section=__ex_table linux linux: file format elf32-i386 Contents of section __ex_table: 82a5048 3e6fdcff bcbaf6ff 396fdcff b4baf6ff >o......9o...... 82a5058 336fdcff acbaf6ff 306fdcff bfbaf6ff 3o......0o...... 82a5068 2b6fdcff 9cbaf6ff 286fdcff afbaf6ff +o......(o...... 82a5078 236fdcff 8cbaf6ff 206fdcff 9fbaf6ff #o...... o...... 82a5088 1b6fdcff 7cbaf6ff 186fdcff 8fbaf6ff .o..|....o...... 82a5098 136fdcff 6cbaf6ff 106fdcff 7fbaf6ff .o..l....o...... 82a50a8 0b6fdcff 5cbaf6ff 086fdcff 6fbaf6ff .o..\....o..o... 82a50b8 036fdcff 4cbaf6ff 006fdcff 5fbaf6ff .o..L....o.._... 82a50c8 fb6edcff 3cbaf6ff f86edcff 4fbaf6ff .n..<....n..O... 82a50d8 f36edcff 2cbaf6ff f06edcff 3fbaf6ff .n..,....n..?... 82a50e8 eb6edcff 1cbaf6ff e86edcff 2fbaf6ff .n.......n../... 82a50f8 e36edcff 0cbaf6ff e06edcff 1fbaf6ff .n.......n...... 82a5108 db6edcff fcb9f6ff d86edcff 0fbaf6ff .n.......n...... 82a5118 d36edcff ecb9f6ff d06edcff ffb9f6ff .n.......n...... 82a5128 cb6edcff dcb9f6ff c86edcff efb9f6ff .n.......n...... 82a5138 c36edcff ccb9f6ff c06edcff dfb9f6ff .n.......n...... 82a5148 bb6edcff bcb9f6ff b86edcff cfb9f6ff .n.......n...... 82a5158 ce6edcff acb9f6ff cc6edcff bfb9f6ff .n.......n...... 82a5168 cf6edcff 9cb9f6ff c96edcff afb9f6ff .n.......n...... Let pick the first instruction location '3e6fdcff' (in human readable is 0xffdc6f3e). My question is how to find which function in UML kernel has an instruction in location 0xffdc6f3e? In i386 platform, the kernel address greater than the __PAGE_OFFSET (0xC0000000). However, as skas0 sperate the uml kernel and user process address space, it dose work by search address greater than the __PAGE_OFFSET for UML. thanks ------------------------------------------------------------------------------ Time is money.
