|
|
* Error codes
|
|
*
|
|
* Return status codes as used within iPXE are designed to allow for
|
|
* maximum visibility into the source of an error even in an end-user
|
|
* build with no debugging. They are constructed as follows:
|
|
*
|
|
* Bits 7-0 : Platform-specific error code
|
|
*
|
|
* This is a losslessly compressed representation of the closest
|
|
* equivalent error code defined by the platform (e.g. BIOS/PXE or
|
|
* EFI). It is used to generate errors to be returned to external
|
|
* code.
|
|
*
|
|
* Bits 12-8 : Per-file disambiguator
|
|
*
|
|
* When the same error code can be generated from multiple points
|
|
* within a file, this field can be used to identify the unique
|
|
* instance.
|
|
*
|
|
* Bits 23-13 : File identifier
|
|
*
|
|
* This is a unique identifier for the file generating the error
|
|
* (e.g. ERRFILE_tcp for tcp.c).
|
|
*
|
|
* Bits 30-24 : POSIX error code
|
|
*
|
|
* This is the closest equivalent POSIX error code (e.g. ENOMEM).
|
|
*
|
|
* Bit 31 : Reserved
|
|
*
|
|
* Errors are usually return as negative error codes (e.g. -EINVAL);
|
|
* bit 31 is therefore unusable.
|
|
*
|
|
*
|
|
* The convention within the code is that errors are negative and
|
|
* expressed using the POSIX error, e.g.
|
|
*
|
|
* return -EINVAL;
|
|
*
|
|
* By various bits of preprocessor magic, the platform-specific error
|
|
* code and file identifier are already incorporated into the
|
|
* definition of the POSIX error macro, which keeps the code
|
|
* relatively clean.
|
|
*
|
|
*
|
|
* Functions that wish to return failures should be declared as
|
|
* returning an integer @c rc "Return status code". A return value of
|
|
* zero indicates success, a non-zero value indicates failure. The
|
|
* return value can be passed directly to strerror() in order to
|
|
* generate a human-readable error message, e.g.
|
|
*
|
|
* if ( ( rc = some_function ( ... ) ) != 0 ) {
|
|
* DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
|
|
* return rc;
|
|
* }
|
|
*
|
|
* As illustrated in the above example, error returns should generally
|
|
* be directly propagated upward to the calling function.
|
|
*
|
|
*
|
|
* Individual files may declare localised errors using
|
|
* __einfo_uniqify(). For example, iscsi.c declares a localised
|
|
* version of EACCES for the error of "access denied due to incorrect
|
|
* target username":
|
|
*
|
|
* #define EACCES_INCORRECT_TARGET_USERNAME \
|
|
* __einfo_error ( EINFO_EACCES_INCORRECT_TARGET_USERNAME )
|
|
* #define EINFO_EACCES_INCORRECT_TARGET_USERNAME \
|
|
* __einfo_uniqify ( EINFO_EACCESS, 0x01, "Incorrect target username" )
|
|
*
|
|
* which can then be used as:
|
|
*
|
|
* return -EACCES_INCORRECT_TARGET_USERNAME;
|
|
*
