In rtld's map_object(), use pread(..., 0) rather than read() to read the ELF header from the front of the file. As all other I/O on the binary is done using mmap(), this avoids the need for seek privileges on the file descriptor during run-time linking. Sponsored by: Google

Do the first step in removing lukemftpd from the base system. Disconnect it from the build. If you are using the FTP daemon, please consider using the port ftp/tnftpd which is the same FTP server, but newer and might have more/better functionality. This results in us providing only one ftp daemon by default. Reviewed by: bz Approved by: imp (mentor, implicit) MFC after: 3 days Silence from: obrien Approved by: re (kib), imp (mentor, implicit)
