* utils: fix buffer reallocation of nft_fprinft()Arturo Borrero2014-05-131-3/+10
| | | | | | | | | | | | | | | | When _snprintf() reports it would print n characters, that n doesn't include the trailing \0 that snprintf adds. Thus, we need to [re]allocate n+1 characters. While at it, change the reallocation trigger. If the length of the buffer we used is equals to the expanded string length, the output has been truncated. In other words, if ret == bufsiz, then the trailing \0 is missing. Also, check if _snprintf() returned < 0, which means an error ocurred.

* internal: fix SNPRINTF_BUFFER_SIZE macroArturo Borrero2014-05-131-2/+4
| | | | | | | | | | | | | | | | | | | | | We need to store in 'offset' the complete amount of characters as returned from _snprintf. The value means how many characters long needs the buffer to be in order to store the corresponding string expansion. Before this patch, in cases where the buffer is smaller than the expansion, then ret > len, and therefore ret = len. So when incrementing offset, we do it with a wrong value. All previous versions of libnftnl are unable to handle this situations: small buffers (or long string expansion). BTW, if a caller must reallocate a buffer to the returned value of snprintf, it should be ret + 1. While at it, let's add a check to know if the last snprintf call failed.

Fix this by checking if the attribute is unset, otherwise skip the assertion checking. Now that we have that nft_assert takes the data parameter, we can also validate if someone is using the setter passing NULL, which is illegal. So let's add an assertion for that as well.
