  23. * Error codes
  24. *
  25. * Return status codes as used within iPXE are designed to allow for
  26. * maximum visibility into the source of an error even in an end-user
  27. * build with no debugging. They are constructed as follows:
  28. *
  29. * Bits 7-0 : PXE error code
  30. *
  31. * This is the closest equivalent PXE error code
  32. * (e.g. PXENV_STATUS_OUT_OF_RESOURCES), and is the only part of the
  33. * error that will be returned via the PXE API, since PXE has
  34. * predefined error codes.
  35. *
  36. * Bits 12-8 : Per-file disambiguator
  37. *
  38. * When the same error number can be generated from multiple points
  39. * within a file, this field can be used to identify the unique
  40. * instance.
  41. *
  42. * Bits 23-13 : File identifier
  43. *
  44. * This is a unique identifier for the file generating the error
  45. * (e.g. ERRFILE_tcp for tcp.c).
  46. *
  47. * Bits 30-24 : POSIX error code
  48. *
  49. * This is the closest equivalent POSIX error code (e.g. ENOMEM).
  50. *
  51. * Bit 31 : Reserved
  52. *
  53. * Errors are usually return as negative error numbers (e.g. -EINVAL);
  54. * bit 31 is therefore unusable.
  55. *
  56. *
  57. * The convention within the code is that errors are negative and
  58. * expressed using the POSIX error, e.g.
  59. *
  60. * return -EINVAL;
  61. *
  62. * By various bits of preprocessor magic, the PXE error code and file
  63. * identifier are already incorporated into the definition of the
  64. * POSIX error macro, which keeps the code relatively clean.
  65. *
  66. *
  67. * Functions that wish to return failures should be declared as
  68. * returning an integer @c rc "Return status code". A return value of
  69. * zero indicates success, a non-zero value indicates failure. The
  70. * return value can be passed directly to strerror() in order to
  71. * generate a human-readable error message, e.g.
  72. *
  73. * if ( ( rc = some_function ( ... ) ) != 0 ) {
  74. * DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
  75. * return rc;
  76. * }
  77. *
  78. * As illustrated in the above example, error returns should generally
  79. * be directly propagated upward to the calling function.
  80. *
  81. *
  82. * Individual files may declare localised errors using
  83. * __einfo_uniqify(). For example, iscsi.c declares a localised
  84. * version of EACCES for the error of "access denied due to incorrect
  85. * target username":
  86. *
  87. * #define EACCES_INCORRECT_TARGET_USERNAME \
  88. * __einfo_error ( EINFO_EACCES_INCORRECT_TARGET_USERNAME )
  89. * #define EINFO_EACCES_INCORRECT_TARGET_USERNAME \
  90. * __einfo_uniqify ( EINFO_EACCESS, 0x01, "Incorrect target username" )
  91. *
  92. * which can then be used as:
  93. *
  94. * return -EACCES_INCORRECT_TARGET_USERNAME;
  95. *
