the second part of that earlier post. again, following the theme from LDD3, ch 4: http://lwn.net/Kernel/LDD3/ Q1: if i'm just debugging the kernel, i can see the kernel ELF section breakdown with: (gdb) info files after i run "add-symbol-file" for a loaded module, is there a similar command that will show me the change now that i've added those extra symbols? certainly, running "info files" doesn't give me any different output. what's the easiest way to verify the new "content" that's been added to my current gdb session? or do i just have to *know* the symbols that are newly available? Q2: if i want to update my current symbol contents for kernel symbols, i have to run: (gdb) core-file /proc/kcore to reload. i have to do exactly the same thing for module contents as well, correct? after all, once a module is loaded, it's all part of /proc/kcore, yes? Q3: if i've loaded the symbol table for a module section, then unloaded the module, what happens if i try to print one of its (now removed) symbols? i guess i could test that, and i'm assuming it wouldn't be fatal, but i'd rather not test it only to have the system crash. rday p.s. i suspect i can see which symbols come and go by constantly checking the contents of /proc/kallsyms. i'm sure that would work. -- ======================================================================== Robert P.
