7 | +Assembler Annotations |
8 | +===================== |
9 | + |
10 | +Copyright (c) 2017-2019 Jiri Slaby |
11 | + |
12 | +This document describes the new macros for annotation of data and code in |
13 | +assembly. In particular, it contains information about ``SYM_FUNC_START``, |
14 | +``SYM_FUNC_END``, ``SYM_CODE_START``, and similar. |
15 | + |
16 | +Rationale |
17 | +--------- |
18 | +Some code like entries, trampolines, or boot code needs to be written in |
19 | +assembly. The same as in C, such code is grouped into functions and |
20 | +accompanied with data. Standard assemblers do not force users into precisely |
21 | +marking these pieces as code, data, or even specifying their length. |
22 | +Nevertheless, assemblers provide developers with such annotations to aid |
23 | +debuggers throughout assembly. On top of that, developers also want to mark |
24 | +some functions as *global* in order to be visible outside of their translation |
25 | +units. |
26 | + |
27 | +Over time, the Linux kernel has adopted macros from various projects (like |
28 | +``binutils``) to facilitate such annotations. So for historic reasons, |
29 | +developers have been using ``ENTRY``, ``END``, ``ENDPROC``, and other |
30 | +annotations in assembly. Due to the lack of their documentation, the macros |
31 | +are used in rather wrong contexts at some locations. Clearly, ``ENTRY`` was |
32 | +intended to denote the beginning of global symbols (be it data or code). |
33 | +``END`` used to mark the end of data or end of special functions with |
34 | +*non-standard* calling convention. In contrast, ``ENDPROC`` should annotate |
35 | +only ends of *standard* functions. |
36 | + |
37 | +When these macros are used correctly, they help assemblers generate a nice |
38 | +object with both sizes and types set correctly. For example, the result of |
39 | +``arch/x86/lib/putuser.S``:: |
40 | + |
41 | + Num: Value Size Type Bind Vis Ndx Name |
42 | + 25: 0000000000000000 33 FUNC GLOBAL DEFAULT 1 __put_user_1 |
43 | + 29: 0000000000000030 37 FUNC GLOBAL DEFAULT 1 __put_user_2 |
44 | + 32: 0000000000000060 36 FUNC GLOBAL DEFAULT 1 __put_user_4 |
45 | + 35: 0000000000000090 37 FUNC GLOBAL DEFAULT 1 __put_user_8 |
46 | + |
47 | +This is not only important for debugging purposes. When there are properly |
48 | +annotated objects like this, tools can be run on them to generate more useful |
49 | +information. In particular, on properly annotated objects, ``objtool`` can be |
50 | +run to check and fix the object if needed. Currently, ``objtool`` can report |
51 | +missing frame pointer setup/destruction in functions. It can also |
52 | +automatically generate annotations for :doc:`ORC unwinder <x86/orc-unwinder>` |
53 | +for most code. Both of these are especially important to support reliable |
54 | +stack traces which are in turn necessary for :doc:`Kernel live patching |
55 | +<livepatch/livepatch>`. |
56 | + |
57 | +Caveat and Discussion |
58 | +--------------------- |
59 | +As one might realize, there were only three macros previously. That is indeed |
60 | +insufficient to cover all the combinations of cases: |
61 | + |
62 | +* standard/non-standard function |
63 | +* code/data |
64 | +* global/local symbol |
65 | + |
66 | +There was a discussion_ and instead of extending the current ``ENTRY/END*`` |
67 | +macros, it was decided that brand new macros should be introduced instead:: |
68 | + |
69 | + So how about using macro names that actually show the purpose, instead |
70 | + of importing all the crappy, historic, essentially randomly chosen |
71 | + debug symbol macro names from the binutils and older kernels? |
72 | + |
73 | +.. _discussion: https://lkml.kernel.org/r/20170217104757.28588-1-jslaby@suse.cz |
74 | + |
75 | +Macros Description |
76 | +------------------ |
77 | + |
78 | +The new macros are prefixed with the ``SYM_`` prefix and can be divided into |
79 | +three main groups: |
80 | + |
81 | +1. ``SYM_FUNC_*`` -- to annotate C-like functions. This means functions with |
82 | + standard C calling conventions, i.e. the stack contains a return address at |
83 | + the predefined place and a return from the function can happen in a |
84 | + standard way. When frame pointers are enabled, save/restore of frame |
85 | + pointer shall happen at the start/end of a function, respectively, too. |
86 | + |
87 | + Checking tools like ``objtool`` should ensure such marked functions conform |
88 | + to these rules. The tools can also easily annotate these functions with |
89 | + debugging information (like *ORC data*) automatically. |
90 | + |
91 | +2. ``SYM_CODE_*`` -- special functions called with special stack. Be it |
92 | + interrupt handlers with special stack content, trampolines, or startup |
93 | + functions. |
94 | + |
95 | + Checking tools mostly ignore checking of these functions. But some debug |
96 | + information still can be generated automatically. For correct debug data, |
97 | + this code needs hints like ``UNWIND_HINT_REGS`` provided by developers. |
98 | + |
99 | +3. ``SYM_DATA*`` -- obviously data belonging to ``.data`` sections and not to |
100 | + ``.text``. Data do not contain instructions, so they have to be treated |
101 | + specially by the tools: they should not treat the bytes as instructions, |
102 | + nor assign any debug information to them. |
103 | + |
104 | +Instruction Macros |
105 | +~~~~~~~~~~~~~~~~~~ |
106 | +This section covers ``SYM_FUNC_*`` and ``SYM_CODE_*`` enumerated above. |
107 | + |
108 | +* ``SYM_FUNC_START`` and ``SYM_FUNC_START_LOCAL`` are supposed to be **the |
109 | + most frequent markings**. They are used for functions with standard calling |
110 | + conventions -- global and local. Like in C, they both align the functions to |
111 | + architecture specific ``__ALIGN`` bytes. There are also ``_NOALIGN`` variants |
112 | + for special cases where developers do not want this implicit alignment. |
113 | + |
114 | + ``SYM_FUNC_START_WEAK`` and ``SYM_FUNC_START_WEAK_NOALIGN`` markings are |
115 | + also offered as an assembler counterpart to the *weak* attribute known from |
116 | + C. |
117 | + |
118 | + All of these **shall** be coupled with ``SYM_FUNC_END``. First, it marks |
119 | + the sequence of instructions as a function and computes its size to the |
120 | + generated object file. Second, it also eases checking and processing such |
121 | + object files as the tools can trivially find exact function boundaries. |
122 | + |
123 | + So in most cases, developers should write something like in the following |
124 | + example, having some asm instructions in between the macros, of course:: |
125 | + |
126 | + SYM_FUNC_START(function_hook) |
127 | + ... asm insns ... |
128 | + SYM_FUNC_END(function_hook) |
129 | + |
130 | + In fact, this kind of annotation corresponds to the now deprecated ``ENTRY`` |
131 | + and ``ENDPROC`` macros. |
132 | + |
133 | +* ``SYM_FUNC_START_ALIAS`` and ``SYM_FUNC_START_LOCAL_ALIAS`` serve for those |
134 | + who decided to have two or more names for one function. The typical use is:: |
135 | + |
136 | + SYM_FUNC_START_ALIAS(__memset) |
137 | + SYM_FUNC_START(memset) |
138 | + ... asm insns ... |
139 | + SYM_FUNC_END(memset) |
140 | + SYM_FUNC_END_ALIAS(__memset) |
141 | + |
142 | + In this example, one can call ``__memset`` or ``memset`` with the same |
143 | + result, except the debug information for the instructions is generated to |
144 | + the object file only once -- for the non-``ALIAS`` case. |
145 | + |
146 | +* ``SYM_CODE_START`` and ``SYM_CODE_START_LOCAL`` should be used only in |
147 | + special cases -- if you know what you are doing. This is used exclusively |
148 | + for interrupt handlers and similar where the calling convention is not the C |
149 | + one. ``_NOALIGN`` variants exist too. The use is the same as for the ``FUNC`` |
150 | + category above:: |
151 | + |
152 | + SYM_CODE_START_LOCAL(bad_put_user) |
153 | + ... asm insns ... |
154 | + SYM_CODE_END(bad_put_user) |
155 | + |
156 | + Again, every ``SYM_CODE_START*`` **shall** be coupled by ``SYM_CODE_END``. |
157 | + |
158 | + To some extent, this category corresponds to deprecated ``ENTRY`` and |
159 | + ``END``. Except ``END`` had several other meanings too. |
160 | + |
161 | +* ``SYM_INNER_LABEL*`` is used to denote a label inside some |
162 | + ``SYM_{CODE,FUNC}_START`` and ``SYM_{CODE,FUNC}_END``. They are very similar |
163 | + to C labels, except they can be made global. An example of use:: |
164 | + |
165 | + SYM_CODE_START(ftrace_caller) |
166 | + /* save_mcount_regs fills in first two parameters */ |
167 | + ... |
168 | + |
169 | + SYM_INNER_LABEL(ftrace_caller_op_ptr, SYM_L_GLOBAL) |
170 | + /* Load the ftrace_ops into the 3rd parameter */ |
171 | + ... |
172 | + |
173 | + SYM_INNER_LABEL(ftrace_call, SYM_L_GLOBAL) |
174 | + call ftrace_stub |
175 | + ... |
176 | + retq |
177 | + SYM_CODE_END(ftrace_caller) |
178 | + |
179 | +Data Macros |
180 | +~~~~~~~~~~~ |
181 | +Similar to instructions, there is a couple of macros to describe data in the |
182 | +assembly. |
183 | + |
184 | +* ``SYM_DATA_START`` and ``SYM_DATA_START_LOCAL`` mark the start of some data |
185 | + and shall be used in conjunction with either ``SYM_DATA_END``, or |
186 | + ``SYM_DATA_END_LABEL``. The latter adds also a label to the end, so that |
187 | + people can use ``lstack`` and (local) ``lstack_end`` in the following |
188 | + example:: |
189 | + |
190 | + SYM_DATA_START_LOCAL(lstack) |
191 | + .skip 4096 |
192 | + SYM_DATA_END_LABEL(lstack, SYM_L_LOCAL, lstack_end) |
193 | + |
194 | +* ``SYM_DATA`` and ``SYM_DATA_LOCAL`` are variants for simple, mostly one-line |
195 | + data:: |
196 | + |
197 | + SYM_DATA(HEAP, .long rm_heap) |
198 | + SYM_DATA(heap_end, .long rm_stack) |
199 | + |
200 | + In the end, they expand to ``SYM_DATA_START`` with ``SYM_DATA_END`` |
201 | + internally. |
202 | + |
203 | +Support Macros |
204 | +~~~~~~~~~~~~~~ |
205 | +All the above reduce themselves to some invocation of ``SYM_START``, |
206 | +``SYM_END``, or ``SYM_ENTRY`` at last. Normally, developers should avoid using |
207 | +these. |
208 | + |
209 | +Further, in the above examples, one could see ``SYM_L_LOCAL``. There are also |
210 | +``SYM_L_GLOBAL`` and ``SYM_L_WEAK``. All are intended to denote linkage of a |
211 | +symbol marked by them. They are used either in ``_LABEL`` variants of the |
212 | +earlier macros, or in ``SYM_START``. |
213 | + |
214 | + |
215 | +Overriding Macros |
216 | +~~~~~~~~~~~~~~~~~ |
217 | +Architecture can also override any of the macros in their own |
218 | +``asm/linkage.h``, including macros specifying the type of a symbol |
219 | +(``SYM_T_FUNC``, ``SYM_T_OBJECT``, and ``SYM_T_NONE``). As every macro |
220 | +described in this file is surrounded by ``#ifdef`` + ``#endif``, it is enough |
221 | +to define the macros differently in the aforementioned architecture-dependent |
222 | +header. |
