module: set ksymtab/kcrctab* section addresses to 0x0
These __ksymtab*/__kcrctab* sections currently have non-zero addresses.
Non-zero section addresses in a relocatable ELF confuse GDB and it ends
up not relocating all symbols when add-symbol-file is used on modules
which have exports. The kernel's module loader does not care about
these addresses, so let's just set them to zero.
Before:
$ readelf -S lib/notifier-error-inject.ko | grep 'Name\| __ksymtab_gpl'
[Nr] Name Type Addr Off Size ES Flg Lk Inf Al
[ 8] __ksymtab_gpl PROGBITS 0000000c 0001b4 000010 00 A 0 0 4
(gdb) add-symbol-file lib/notifier-error-inject.ko 0x500000 -s .bss 0x700000
add symbol table from file "lib/notifier-error-inject.ko" at
.text_addr = 0x500000
.bss_addr = 0x700000
(gdb) p ¬ifier_err_inject_dir
$3 = (struct dentry **) 0x0
After:
$ readelf -S lib/notifier-error-inject.ko | grep 'Name\| __ksymtab_gpl'
[Nr] Name Type Addr Off Size ES Flg Lk Inf Al
[ 8] __ksymtab_gpl PROGBITS 00000000 0001b4 000010 00 A 0 0 4
(gdb) add-symbol-file lib/notifier-error-inject.ko 0x500000 -s .bss 0x700000
add symbol table from file "lib/notifier-error-inject.ko" at
.text_addr = 0x500000
.bss_addr = 0x700000
(gdb) p ¬ifier_err_inject_dir
$3 = (struct dentry **) 0x700000
