src/sys/net: bpf_filter.c
Log Message:
Implement error checking in m_xbyte() and check for errors after m_xbyte() call.
Reuse (len - k) expression in m_xword() and m_xhalf() to give an optimization
hint to a compiler.
When m_xbyte() didn't exist, bpf_filter() handled out-of-bounds BPF_B loads
correctly because "return 0" inside MINDEX() was aborting filter programs.
After the change that added m_xbyte() zero values were passed to A or X
registers instead of aborting a filter program.
