kallsyms: remove deprecated print_fn_descriptor_symbol()

2009-12-15T16:53:26+00:00

According to feature-removal-schedule.txt, it is the time to remove
print_fn_descriptor_symbol().

And a quick grep shows that it no longer has any callers.

Ksplice: Add functions for walking kallsyms symbols

2009-03-31T02:35:32+00:00

Impact: New API

kallsyms_lookup_name only returns the first match that it finds.  Ksplice
needs information about all symbols with a given name in order to correctly
resolve local symbols.

kallsyms_on_each_symbol provides a generic mechanism for iterating over the
kallsyms table.

vsprintf: use new vsprintf symbolic function pointer format

2008-10-16T18:21:31+00:00

Use the '%pF' format to get rid of an "#ifdef DEBUG" and make some printks
atomic.

This removes the last in-tree uses of print_fn_descriptor_symbol().  I
marked print_fn_descriptor_symbol() deprecated and scheduled it for
removal next year to give time for out-of-tree modules to be updated.

parisc's print_fn_descriptor_symbol() is currently broken there (it needs
to dereference the function pointer similar to ia64 and power).  This
patch shouldn't make anything worse, but it means we need to fix
dereference_function_descriptor() instead of print_fn_descriptor_symbol()
to get meaningful initcall_debug output.

kallsyms: unify 32- and 64-bit code

2008-07-25T17:53:29+00:00

Use the %p format string which already accounts for the padding you need
with a pointer type on a particular architecture.

Also replace the macro with a static inline function to match the rest of
the file.

Clean up 'print_fn_descriptor_symbol()' types

2008-05-16T00:50:37+00:00

Everybody wants to pass it a function pointer, and in fact, that is what
you _must_ pass it for it to make sense (since it knows that ia64 and
ppc64 use descriptors for function pointers and fetches the actual
address from there).

So don't make the argument be a 'unsigned long' and force everybody to
add a cast.

kallsyms: make KSYM_NAME_LEN include space for trailing '\0'

2007-07-17T17:23:03+00:00

KSYM_NAME_LEN is peculiar in that it does not include the space for the
trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating
buffer.  This is nonsense and error-prone.  Moreover, when the caller
forgets that it's very likely to subtly bite back by corrupting the stack
because the last position of the buffer is always cleared to zero.

This patch increments KSYM_NAME_LEN by one and updates code accordingly.

* off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro
  is fixed.

* Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together,
  MODULE_NAME_LEN was treated as if it didn't include space for the
  trailing '\0'.  Fix it.

Fix race between cat /proc/slab_allocators and rmmod

2007-05-08T18:15:08+00:00

Same story as with cat /proc/*/wchan race vs rmmod race, only
/proc/slab_allocators want more info than just symbol name.
