Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

looping again over the ELF sections we just validated. We can simply
keep tabs of the key sections of interest as we validate the module
ELF section in one swoop, so do that and merge the two routines
together.
Expand a bit on the documentation / intent / goals.

The symbol and strings section validation currently happen in
setup_load_info() but since they are also doing validity checks
move this to elf_validity_check().

The integrity of the struct module we load is important, and although
our ELF validator already checks that the module section must match
struct module, add a stop-gap check before we memcpy() the final minted
module. This also makes those inspecting the code what the goal is.
While at it, clarify the goal behind updating the sh_addr address.
The current comment is pretty misleading.

The ELF ".gnu.linkonce.this_module" section is special, it is what we
use to construct the struct module __this_module, which THIS_MODULE
points to. When userspace loads a module we always deal first with a
copy of the userspace buffer, and twiddle with the userspace copy's
version of the struct module. Eventually we allocate memory to do a
memcpy() of that struct module, under the assumption that the module
size is right. But we have no validity checks against the size or
the requirements for the section.
Add some validity checks for the special module section early and while
at it, cache the module section index early, so we don't have to do that
later.
While at it, just move over the assigment of the info->mod to make the
code clearer. The validity checker also adds an explicit size check to
ensure the module section size matches the kernel's run time size for
sizeof(struct module). This should prevent sloppy loads of modules
which are built today *without* actually increasing the size of
the struct module. A developer today can for example expand the size
of struct module, rebuild a directoroy 'make fs/xfs/' for example and
then try to insmode the driver there. That module would in effect have
an incorrect size. This new size check would put a stop gap against such
mistakes.
This also makes the entire goal of ".gnu.linkonce.this_module" pretty
clear. Before this patch verification of the goal / intent required some
Indian Jones whips, torches and cleaning up big old spider webs.

Converge on a compromise: so long as we have a module hit our linked
list of modules we taint. That is, the module was about to become live.
Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
It is silly to have taints spread out all over, we can just compromise
and add them if the module ever hit our linked list. Our sanity checkers
should just prevent crappy drivers / bogus ELF modules / etc and kconfig
options should be enough to let you *not* load things you don't want.
Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
check_modinfo() actually does two things:
a) sanity checks, some of which are fatal, and so we
prevent the user from completing trying to load a module
b) taints the kernel
The taints are pretty heavy handed because we're tainting the kernel
*before* we ever even get to load the module into the modules linked
list. That is, it it can fail for other reasons later as we review the
module's structure.
But this commit makes no functional changes, it just makes the intent
clearer and splits the code up where needed to make that happen.
Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
The work to taint the kernel due to a module should be split
up eventually. To aid with this, split up the tainting on
check_modinfo_livepatch().
This let's us bring more early checks together which do return
a value, and makes changes easier to read later where we stuff
all the work to do the taints in one single routine.

The set_license() routine would seem to a reader to do some sort of
setting, but it does not. It just adds a taint if the license is
not set or proprietary.
This makes what the code is doing clearer, so much we can remove
the comment about it.
Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
This moves check_modinfo() to early_mod_check(). This
doesn't make any functional changes either, as check_modinfo()
was the first call on layout_and_allocate(), so we're just
moving it back one routine and at the end.
This let's us keep separate the checkers from the allocator.

Move early sanity checkers for the module into a helper.

Use kunmap_local() to unmap pages locally mapped with kmap_local_page().
kunmap_local() must be called on the kernel virtual address returned by
kmap_local_page(), differently from how we use kunmap() which instead
expects the mapped page as its argument.
In module_zstd_decompress() we currently map with kmap_local_page() and
unmap with kunmap(). This breaks the code and so it should be fixed.

Currently, in dynamic_debug.h we only provide
DEFINE_DYNAMIC_DEBUG_METADATA() and DYNAMIC_DEBUG_BRANCH()
definitions if CONFIG_DYNAMIC_CORE is enabled. Thus, drivers
such as infiniband srp (see: drivers/infiniband/ulp/srp/ib_srp.c)
must provide their own definitions for !CONFIG_DYNAMIC_CORE.
Thus, let's move this !CONFIG_DYNAMIC_CORE case into dynamic_debug.h.
However, the dynamic debug interfaces should really only be defined
if CONFIG_DYNAMIC_DEBUG is set or CONFIG_DYNAMIC_CORE is set along
with DYNAMIC_DEBUG_MODULE, (see:
Documentation/admin-guide/dynamic-debug-howto.rst). Thus, the
undefined case becomes: !((CONFIG_DYNAMIC_DEBUG ||
(CONFIG_DYNAMIC_CORE && DYNAMIC_DEBUG_MODULE)).
With those changes in place, we can remove the !CONFIG_DYNAMIC_CORE
case from ib_srp.c
This change was prompted by a build breakeage in ib_srp.c stemming
from the inclusion of dynamic_debug.h unconditionally in module.h, due
to commit 7deabd6749 ("dyndbg: use the module notifier callbacks").
In that case, if we have CONFIG_DYNAMIC_CORE=y and
CONFIG_DYNAMIC_DEBUG=n then the definitions for
DEFINE_DYNAMIC_DEBUG_METADATA() and DYNAMIC_DEBUG_BRANCH() are defined
once in ib_srp.c and then again in the dynamic_debug.h. This had been
working prior to the above referenced commit because dynamic_debug.h
was only pulled into ib_srp.c conditinally via printk.h if
CONFIG_DYNAMIC_DEBUG was set.
Also, the exported functions in lib/dynamic_debug.c itself may
not have a prototype if CONFIG_DYNAMIC_DEBUG=n and
CONFIG_DYNAMIC_CORE=y. This would trigger the -Wmissing-prototypes
warning.
The exported functions are behind (include/linux/dynamic_debug.h):
if defined(CONFIG_DYNAMIC_DEBUG) || \
(defined(CONFIG_DYNAMIC_DEBUG_CORE) && defined(DYNAMIC_DEBUG_MODULE))
Thus, by adding -DDYNAMIC_CONFIG_MODULE to the lib/Makefile we
can ensure that the exported functions have a prototype in all cases,
since lib/dynamic_debug.c is built whenever
CONFIG_DYNAMIC_DEBUG_CORE=y.

There is quite a bit of tribal knowledge around proper use of try_module_get()
and requiring *somehow* the module to still exist to use this call in a way
that is safe. Document this bit of tribal knowledge. To be clear, you should
only use try_module_get() *iff* you are 100% sure the module already does
exist and is not on its way out.
You can be sure the module still exists and is alive through:
1) Direct protection with its refcount: you know some earlier caller called
__module_get() safely
2) Implied protection: there is an implied protection against module removal
Having an idea of when you are sure __module_get() might be called earlier is
easy to understand however the implied protection requires an example. We use
sysfs an an example for implied protection without a direct module reference
count bump. kernfs / sysfs uses its own internal reference counting for files
being actively used, when such file are active they completely prevent
the module from being removed. kernfs protects this with its kernfs_active().
Effort has been put into verifying the kernfs implied protection works by
using a currently out-of-tree test_sysfs selftest test #32 [0]:
./tools/testing/selftests/sysfs/sysfs.sh -t 0032
Without kernfs / sysfs preventing module removal through its active reference
count (kernfs_active()) the write would fail or worse, a crash would happen in
this test and it does not.
Similar safeguards are required for other users of try_module_get() *iff*
they are not ensuring the above rule 1) is followed.

After a change to linux/module.h, dyndbg.h is now included
indirectly from the decompressor for lz4 support, which in turn
causes a build failure on 32-bit Arm:
In file included from include/linux/module.h:30,
from arch/arm/boot/compressed/../../../../lib/lz4/lz4_decompress.c:39,
from arch/arm/boot/compressed/../../../../lib/decompress_unlz4.c:10,
from arch/arm/boot/compressed/decompress.c:59:
include/linux/dynamic_debug.h: In function 'ddebug_dyndbg_module_param_cb':
include/linux/dynamic_debug.h:307:14: error: implicit declaration of function 'strcmp' [-Werror=implicit-function-declaration]

| ^~~~~~
include/linux/dynamic_debug.h:1:1: note: 'strcmp' is defined in header '<string.h>'; did you forget to '#include <string.h>'?
+++ |+#include <string.h>
The decompressor has its own replacement for the linux/string.h contents,
so the normal declaration is not visible here. Since the function is
not actually called, it is sufficient to add a declaration, and this
is in fact the correct one as it matches the definition in
arch/arm/boot/compressed/string.c.

Bring dynamic debug in line with other subsystems by using the module
notifier callbacks. This results in a net decrease in core module
code.
Additionally, Jim Cromie has a new dynamic debug classmap feature,
which requires that jump labels be initialized prior to dynamic debug.
Specifically, the new feature toggles a jump label from the existing
dynamic_debug_setup() function. However, this does not currently work
properly, because jump labels are initialized via the
'module_notify_list' notifier chain, which is invoked after the
current call to dynamic_debug_setup(). Thus, this patch ensures that
jump labels are initialized prior to dynamic debug by setting the
dynamic debug notifier priority to 0, while jump labels have the
higher priority of 1.
Tested by Jim using his new test case, and I've verfied the correct
printing via: # modprobe test_dynamic_debug dyndbg.
