lib: fix return codes when CONFIG_SYS_VSNPRINTF is enabled

2014-01-24T21:59:07+00:00

When CONFIG_SYS_VSNPRINTF is enabled, it protects print operations
such as sprintf, snprintf, vsnprintf, etc., from buffer overflows.
But vsnprintf_internal includes the terminating NULL character in
the calculation of number of characters written. This affects sprintf
and snprintf return values. Fix this issue by setting pointer 'str'
back to the location of the '\0'.

Move bootstage's numbering printing code into a generic place so that it can
be used by tracing also.

vsprintf:fix: Change type returned by ustrtoul

2012-12-13T18:46:02+00:00

The ustrtoul shall convert string defined size (e.g. 1GiB) to unsigned
long type (as its name implies).

Up till now it had returned int, which might cause problems with large
numbers (GiB range), when interpreted as U2 signed numbers.

lib/vsprintf.c: don't special-case pointers to address null

2012-11-02T22:13:29+00:00

The %p format of printf() would print a pointer to address null as
"(null)".  This makes sense in a real OS where a NULL pointer must
never be dereferenced, but this is a bootloader, and there are cases
where accessing the data at address null makes perfect sense.

Remove the special case in lib/vsprintf.c using "#if 0" with a comment
to make clear this was an intentional change and to stop re-adding
this code.

vsprintf: Move function documentation into header file

Now that this is not in common.h, perhaps it is acceptable to move this
documentation into the header file.

Add safe vsnprintf and snprintf library functions

2011-12-17T22:33:20+00:00

From: Sonny Rao 

These functions are useful in U-Boot because they allow a graceful failure
rather than an unpredictable stack overflow when printf() buffers are
exceeded.

Mostly copied from the Linux kernel. I copied vscnprintf and
scnprintf so we can change printf and vprintf to use the safe
implementation but still return the correct values.
