commit c0d9782f5b6d7157635ae2fd782a4b27d55a6013 upstream.
|
|
||||||
|
|
||||||
From the GCC manual:
|
|
||||||
|
|
||||||
copy
|
|
||||||
copy(function)
|
|
||||||
|
|
||||||
The copy attribute applies the set of attributes with which function
|
|
||||||
has been declared to the declaration of the function to which
|
|
||||||
the attribute is applied. The attribute is designed for libraries
|
|
||||||
that define aliases or function resolvers that are expected
|
|
||||||
to specify the same set of attributes as their targets. The copy
|
|
||||||
attribute can be used with functions, variables, or types. However,
|
|
||||||
the kind of symbol to which the attribute is applied (either
|
|
||||||
function or variable) must match the kind of symbol to which
|
|
||||||
the argument refers. The copy attribute copies only syntactic and
|
|
||||||
semantic attributes but not attributes that affect a symbol’s
|
|
||||||
linkage or visibility such as alias, visibility, or weak.
|
|
||||||
The deprecated attribute is also not copied.
|
|
||||||
|
|
||||||
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html
|
|
||||||
|
|
||||||
The upcoming GCC 9 release extends the -Wmissing-attributes warnings
|
|
||||||
(enabled by -Wall) to C and aliases: it warns when particular function
|
|
||||||
attributes are missing in the aliases but not in their target, e.g.:
|
|
||||||
|
|
||||||
void __cold f(void) {}
|
|
||||||
void __alias("f") g(void);
|
|
||||||
|
|
||||||
diagnoses:
|
|
||||||
|
|
||||||
warning: 'g' specifies less restrictive attribute than
|
|
||||||
its target 'f': 'cold' [-Wmissing-attributes]
|
|
||||||
|
|
||||||
Using __copy(f) we can copy the __cold attribute from f to g:
|
|
||||||
|
|
||||||
void __cold f(void) {}
|
|
||||||
void __copy(f) __alias("f") g(void);
|
|
||||||
|
|
||||||
This attribute is most useful to deal with situations where an alias
|
|
||||||
is declared but we don't know the exact attributes the target has.
|
|
||||||
|
|
||||||
For instance, in the kernel, the widely used module_init/exit macros
|
|
||||||
define the init/cleanup_module aliases, but those cannot be marked
|
|
||||||
always as __init/__exit since some modules do not have their
|
|
||||||
functions marked as such.

Subject: [PATCH] include/linux/module.h: copy __init/__exit attrs to
|
|
||||||
init/cleanup_module
|
|
||||||
|
|
||||||
commit a6e60d84989fa0e91db7f236eda40453b0e44afa upstream.
|
|
||||||
|
|
||||||
The upcoming GCC 9 release extends the -Wmissing-attributes warnings
|
|
||||||
(enabled by -Wall) to C and aliases: it warns when particular function
|
|
||||||
attributes are missing in the aliases but not in their target.
|
|
||||||
|
|
||||||
In particular, it triggers for all the init/cleanup_module
|
|
||||||
aliases in the kernel (defined by the module_init/exit macros),
|
|
||||||
ending up being very noisy.
|
|
||||||
|
|
||||||
These aliases point to the __init/__exit functions of a module,
|
|
||||||
which are defined as __cold (among other attributes). However,
|
|
||||||
the aliases themselves do not have the __cold attribute.
|
|
||||||
|
|
||||||
Since the compiler behaves differently when compiling a __cold
|
|
||||||
function as well as when compiling paths leading to calls
|
|
||||||
to __cold functions, the warning is trying to point out
|
|
||||||
the possibly-forgotten attribute in the alias.
|
|
||||||
|
|
||||||
In order to keep the warning enabled, we decided to silence
|
|
||||||
this case. Ideally, we would mark the aliases directly
|
|
||||||
as __init/__exit. However, there are currently around 132 modules
|
|
||||||
in the kernel which are missing __init/__exit in their init/cleanup
|
|
||||||
functions (either because they are missing, or for other reasons,
|
|
||||||
e.g. the functions being called from somewhere else); and
|
|
||||||
a section mismatch is a hard error.
|
|
||||||
|
|
||||||
A conservative alternative was to mark the aliases as __cold only.
|
|
||||||
However, since we would like to eventually enforce __init/__exit
|
|
||||||
to be always marked, we chose to use the new __copy function
|
|
||||||
attribute (introduced by GCC 9 as well to deal with this).
|
|
||||||
With it, we copy the attributes used by the target functions
|
|
||||||
into the aliases. This way, functions that were not marked
|
|
||||||
as __init/__exit won't have their aliases marked either,
|
|
||||||
and therefore there won't be a section mismatch.
|
|
||||||
|
|
||||||
Note that the warning would go away marking either the extern
|
|
||||||
declaration, the definition, or both. However, we only mark
|
|
||||||
the definition of the alias, since we do not want callers
|
|
||||||
(which only see the declaration) to be compiled as if the function
|
|
||||||
was __cold (and therefore the paths leading to those calls
|
|
||||||
would be assumed to be unlikely).
