About kernel upgrade

Question

If I upgrade the kernel,will old binaries use new version of .so or still the old version?

UPDATE

Why kernel has nothing to do with .so?

The kernel has nothing to do with the version of any shared objects.

EDIT:

Because the kernel is the kernel and shared objects are shared objects.

Do you mean kernel upgrade only modifies /proc/kcore ? – kernel Apr 05 '11 at 03:39
The kernel upgrade only changes the kernel and what comes with it. – Ignacio Vazquez-Abrams Apr 05 '11 at 03:41
Doesn't what comes with it include shared objects? – kernel Apr 05 '11 at 03:45
Only the VDSO stuff, which you don't have to care about. – Ignacio Vazquez-Abrams Apr 05 '11 at 03:47
OK,I got that now,thanks!But what if a specific .so is upgraded,will the old binaries that depend on it use new version automatically? – kernel Apr 05 '11 at 03:57
If the SONAME is appropriate, yes. – Ignacio Vazquez-Abrams Apr 05 '11 at 04:06
What if the binary is generated by gcc -l libname xxx? – kernel Apr 05 '11 at 11:25
Then the binary will be linked against that library. – Ignacio Vazquez-Abrams Apr 05 '11 at 11:41
I'm confused ,whether or not will the binary use new version of libname automatically? – kernel Apr 05 '11 at 12:01
The binary will use the library that is available that has an appropriate SONAME. – Ignacio Vazquez-Abrams Apr 05 '11 at 12:03
