How do I list the checksums within a module?
Is there a simpler way to list all the checksums?

I think this one checksum is computed out of all functions that
the module uses.
You've enabled MODULE_SRCVERSION_ALL which adds a checksum computed from the
source files used to build a given module. What I want is to list ALL the
checksums of the symbols included inside a given module.
e.g. for the kernel:
for i in `nm
/lib/modules/2.6.18.8-ccj45-default/kernel/block/as-iosched.ko |
grep " U " | cut -b 20-`; do
grep '\b'"$i"'\b' Module.symvers;
done;
(for 32-bit, use `cut -b 12-`)
I think you didn't understand my request.
I have a *binary* kernel module that was compiled with
CONFIG_MODVERSIONS enabled.
Thus, that binary module includes 32-bit (?) checksums for several
kernel functions AND kernel structures.
cf. my original post:
$ hexdump -C test.ko | grep -A2 struct_
000752e0 17 98 07 0e 73 74 72 75 63 74 5f 6d 6f 64 75 6c
|....struct_modul|
000752f0 65 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
|e...............|
00075300 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
|................|
For example, the checksum for "struct_module" seems to be 0x1798070e.
Is there a tool (from linux-module-init-tools?) to list all the
checksums included in a binary module.
Regards.
