2019-07-23libpayload/libc: Correct strlcat return valueJacob Garber
The documented return value for strlcat is horribly wrong, as is the return value itself. It should not return the number of appended bytes, but rather the length of the concatenated string. From the man page: The strlcpy() and strlcat() functions return the total length of the string they tried to create. For strlcpy() that means the length of src. For strlcat() that means the initial length of dst plus the length of src. While this may seem somewhat confusing, it was done to make truncation detection simple. This change is more likely to fix existing code than break it, since anyone who uses the return value of strlcat will almost certainly rely on the standard behaviour rather than investigate coreboot's source code to see that we have a quirky version.

2019-04-10libpayload: Deduplicate strtol and strtoullJulius Werner
Our strtol() and strtoull() function contain almost exactly the same code. This is a) bad in general and b) may cause the code to get out of sync, such as it recently happened with CB:32029. This patch changes strtol() to be based on strtoull() so that the main parsing code exists only once, and also adds a strtoll() to round off the library. Also fix the bounds imposed by strtoul() to be based on the actual length of a 'long', not hardcoded to 32-bits (which is not equivalent on all architectures).

2019-03-26libpayload: strtoull: Fix edge case bug with *endptrJulius Werner
strtoull() can optionally take a second pointer as an out-parameter that will be adjusted to point to the end of the parsed string. This works almost right, but misses two important edge cases: firstly,when the parsed string is "0", the function will interpret the leading '0' as an octal prefix, so that the first actually parsed digit is already the terminating '\0' byte. This will cause the function to early abort, which still (correctly) returns 0 but doesn't adjust *endptr. The early abort is pointless anyway -- the only other thing the function does is run a for-loop whose condition is the exact inverse (so it's guaranteed to run zero iterations in this case) and then adjust *endptr (which we want). So just take it out. This also technically corrects the behavior of *endptr for a completely invalid string, since the strtoull man page says > If there were no digits at all, strtoul() stores the original value of > nptr in *endptr (and returns 0). The second issue occurs when the parsed string is "0x" without another valid digit behind it. In this case, we will still jump over the 0x prefix so that *endptr is set to the first byte after that. The correct interpretation in this case is that there is no 0x prefix, and instead a valid 0 digit with the 'x' being invalid garbage at the end. By not skipping the prefix unless there's at least one valid digit after it, we get the correct behavior of *endptr pointing to the 'x'.
