njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 37 | |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 38 | Function wrapping and function replacement are similar but not |
| 39 | identical. |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 40 | |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 41 | A replacement for some function F simply diverts all calls to F |
| 42 | to the stated replacement. There is no way to get back to F itself |
| 43 | from the replacement. |
| 44 | |
| 45 | A wrapper for a function F causes all calls to F to instead go to |
| 46 | the wrapper. However, from inside the wrapper, it is possible |
| 47 | (with some difficulty) to get to F itself. |
| 48 | |
| 49 | You may notice that replacement is a special case of wrapping, in |
| 50 | which the call to the original is omitted. For implementation |
| 51 | reasons, though, it is important to use the following macros |
| 52 | correctly: in particular, if you want to write a replacement, make |
| 53 | sure you use the VG_REPLACE_FN_ macros and not the VG_WRAP_FN_ |
| 54 | macros. |
| 55 | |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 56 | Finally there is the concept of prioritised behavioural equivalence |
| 57 | tags. A tag is a 5-digit decimal number (00000 to 99999) encoded |
| 58 | in the name. The top 4 digits are the equivalence class number, |
| 59 | and the last digit is a priority. |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 60 | |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 61 | When processing redirections at library load time, if the set of |
| 62 | available specifications yields more than one replacement or |
| 63 | wrapper function for a given address, the system will try to |
| 64 | resolve the situation by examining the tags on the |
| 65 | replacements/wrappers. |
| 66 | |
| 67 | If two replacement/wrapper functions have the same tag and |
| 68 | priority, then the redirection machinery will assume they have |
| 69 | identical behaviour and can choose between them arbitrarily. If |
| 70 | they have the same tag but different priorities, then the one with |
| 71 | higher priority will be chosen. If neither case holds, then the |
| 72 | redirection is ambiguous and the system will ignore one of them |
| 73 | arbitrarily, but print a warning when running at -v or above. |
| 74 | |
| 75 | The tag is mandatory and must comprise 5 decimal digits. The tag |
| 76 | 00000 is special and means "does not have behaviour identical to any |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 77 | other replacement/wrapper function". Hence if you wish to write a |
| 78 | wrap/replacement function that is not subject to the above |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 79 | resolution rules, use 00000 for the tag. Tags 00001 through 00009 |
| 80 | may not be used for any purpose. |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 81 | |
| 82 | |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 83 | Replacement |
| 84 | ~~~~~~~~~~~ |
| 85 | To write a replacement function, do this: |
| 86 | |
| 87 | ret_type |
| 88 | VG_REPLACE_FUNCTION_ZU(zEncodedSoname,fnname) ( .. args .. ) |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 89 | { |
| 90 | ... body ... |
| 91 | } |
| 92 | |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 93 | zEncodedSoname should be a Z-encoded soname (see below for |
| 94 | Z-encoding details) and fnname should be an unencoded fn name. A |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 95 | default-safe equivalence tag of 00000 is assumed (see comments |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 96 | above). The resulting name is |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 97 | |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 98 | _vgr00000ZU_zEncodedSoname_fnname |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 99 | |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 100 | The "_vgr00000ZU_" is a prefix that gets discarded upon decoding. |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 101 | It identifies this function as a replacement and specifies its |
| 102 | equivalence tag. |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 103 | |
| 104 | It is also possible to write |
| 105 | |
| 106 | ret_type |
| 107 | VG_REPLACE_FUNCTION_ZZ(zEncodedSoname,zEncodedFnname) ( .. args .. ) |
| 108 | { |
| 109 | ... body ... |
| 110 | } |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 111 | |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 112 | which means precisely the same, but the function name is also |
| 113 | Z-encoded. This can sometimes be necessary. In this case the |
| 114 | resulting function name is |
| 115 | |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 116 | _vgr00000ZZ_zEncodedSoname_zEncodedFnname |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 117 | |
| 118 | When it sees this either such name, the core's symbol-table reading |
| 119 | machinery and redirection machinery first Z-decode the soname and |
| 120 | if necessary the fnname. They are encoded so that they may include |
| 121 | arbitrary characters, and in particular they may contain '*', which |
| 122 | acts as a wildcard. |
| 123 | |
| 124 | They then will conspire to cause calls to any function matching |
| 125 | 'fnname' in any object whose soname matches 'soname' to actually be |
| 126 | routed to this function. This is used in Valgrind to define dozens |
| 127 | of replacements of malloc, free, etc. |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 128 | |
| 129 | The soname must be a Z-encoded bit of text because sonames can |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 130 | contain dots etc which are not valid symbol names. The function |
| 131 | name may or may not be Z-encoded: to include wildcards it has to be, |
| 132 | but Z-encoding C++ function names which are themselves already mangled |
| 133 | using Zs in some way is tedious and error prone, so the _ZU variant |
| 134 | allows them not to be Z-encoded. |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 135 | |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 136 | Note that the soname "NONE" is specially interpreted to match any |
| 137 | shared object which doesn't have a soname. |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 138 | |
| 139 | Note also that the replacement function should probably (must be?) in |
| 140 | client space, so it runs on the simulated CPU. So it must be in |
njn | 7b4e5ba | 2005-08-25 22:53:57 +0000 | [diff] [blame] | 141 | either vgpreload_<tool>.so or vgpreload_core.so. It also only works |
| 142 | with functions in shared objects, I think. |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 143 | |
sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 144 | It is important that the Z-encoded names contain no unencoded |
| 145 | underscores, since the intercept-handlers in m_redir.c detect the |
| 146 | end of the soname by looking for the first trailing underscore. |
njn | 16eeb4e | 2005-06-16 03:56:58 +0000 | [diff] [blame] | 147 | |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 148 | To write function names which explicitly state the equivalence class |
| 149 | tag, use |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 150 | VG_REPLACE_FUNCTION_EZU(5-digit-tag,zEncodedSoname,fnname) |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 151 | or |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 152 | VG_REPLACE_FUNCTION_EZZ(5-digit-tag,zEncodedSoname,zEncodedFnname) |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 153 | |
sewardj | 9604484 | 2011-08-18 13:09:55 +0000 | [diff] [blame] | 154 | As per comments above, the tag must be a 5 digit decimal number, |
| 155 | padded with leading zeroes, in the range 00010 to 99999 inclusive. |
sewardj | 85cf900 | 2011-08-16 09:54:00 +0000 | [diff] [blame] | 156 | |

sewardj | 0ec07f3 | 2006-01-12 12:32:32 +0000 | [diff] [blame] | 158 | Wrapping |
| 159 | ~~~~~~~~ |
| 160 | This is identical to replacement, except that you should use the |
| 161 | macro names |

| 169 | |
| 170 | Z-encoding |
| 171 | ~~~~~~~~~~ |
| 172 | Z-encoding details: the scheme is like GHC's. It is just about |
| 173 | readable enough to make a preprocessor unnecessary. First the |
| 174 | "_vgrZU_" or "_vgrZZ_" prefix is added, and then the following |
| 175 | characters are transformed. |

| 177 | * --> Za (asterisk) |
