Libsmbios is a cross-platform library intended to be used to obtain common information available in a BIOS. Major features include the ability to update the BIOS on Dell systems (in conjunction with the Dell RBU Linux kernel driver), programmatic access to information in SMBIOS tables, and the ability to obtain Dell system-specific information such as the Dell System ID number, service tag, and asset tag. Future plans include APIs for $PIR and mptable mapping. There is a C API for some of the more commonly used functions, and example binaries to show off most of the facilities.
SPF is a new strategy for preventing junk mail. The present SMTP standard for email allows anyone to forge anyone else's email address. SPF verifies that the Sender address of an email message matches (according to some policy) the client IP address that submitted it. libspf2 is a complete and robust implementation of SPF which provides support for many MTAs. Support for new MTAs is in progress.
libstream is a fast I/O stream library written in C. It supports common stringstream operations such as read(), write(), and peak(). Instead of using one large buffer, libstream splits its internal buffer into a linked list of fixed-size chunks, thus featuring a more efficient memory footprint. There are no external dependencies.
