Description of problem: core(5) man page shows incorrect default value for coredump_filter. It should show 0x33 Also, just above this point it lists meanings for bits 0-3, but there are meanings for bits 4-6. Version-Release number of selected component (if applicable): man-pages-3.22-20.el6.noarch How reproducible: 100% Steps to Reproduce: 1. man core 2. /coredump_filter Actual results: Shows following text: bit 0 Dump anonymous private mappings. bit 1 Dump anonymous shared mappings. bit 2 Dump file-backed private mappings. bit 3 Dump file-backed shared mappings. The default value of coredump_filter is 0x3; this reflects traditional Linux behavior and means that only anonymous memory segments are dumped. Expected results: Lists values for all relevant bits, and specifies the default value of coredump_filter is 0x33. Additional info: The remaining bits should be: bit 4 Dump ELF headers. bit 5 Dump huge pages that have private mappings bit 6 Dump huge pages that have shared mappings.
