BusyBox v1.16.2 (2010-09-15 14:10:38 CST) multi-call binary.

Usage: ping [OPTIONS] HOST

Send ICMP ECHO_REQUEST packets to network hosts

Options:

-4, -6 Force IP or IPv6 name resolution

-c CNT Send only CNT pings

-s SIZE Send SIZE data bytes in packets (default:56)

-I IFACE/IP Use interface or IP address as source

-W SEC Seconds to wait for the first response (default:10)

(after all -c CNT packets are sent)

-w SEC Seconds until ping exits (default:infinite)

(can exit earlier with -c CNT)

-q Quiet, only displays output at start

and when finished

Follow-ups

--- Sonic Zhang 2010-09-16 04:39:59

Fixed. Should check address range across the border of init section and generic

allocable memory properly.

When init section is released to kernel memory management system, it may be

merged into the same buddy block if it is adjacent to generic allocable memory

region. In this case, an address range may across the border.

--- Sonic Zhang 2010-09-24 22:12:11

instead of changing the access_ok(), adjust the memory_start address to cover

init section.

--- angelia wu 2010-10-12 23:52:27

ok,now the test is ok.

so i closed the bug 6254.
