tron 66ac2330dc Teach dhclient(8) to exit gracefully if another instance is already 
running instead of overwriten the PID file, removing IPv4 address
from the network interface(s) and leaving the system in a broken state.

This fixes PR bin/26504 by Jun-ichiro itojun Hagino. Patch supplied
by Rivo Nurges during NetBSD's second Bugathon.

This avoids using potentially garbage data returned if the ethernet
driver returns a packet that's too long.

itojun 937e8b0fbe add O_TRUNC to open(2). revision 1.11 used fopen(foo, "w") which implies 
truncation of opened file.  it should suppress bogus "corrupted lease file"
warning and broken dhclient.leases staying around.

darrenr 221fa57241 With recent changes to BPF, pushing the default buffer size to 1MB, running 
a bunch of small daemons that seem small packet flows can easily chew up
significant kernel memory (each BPF device opened takes 2*buffersize of
wired memory.)  In each of these applications, add code to set the buffer
size to 32k before setting the interface.

nakayama 083eb7818c Use _LP64 to indicate 64-bit platform, per suggestion on source-changes@. 2004-04-05 13:06:23 +00:00
nakayama cf7c3ba713 s/__sparc_v9__/__sparc64__/ 
"gcc -m32 -mcpu=ultrasparc" defines __sparc_v9__, so __sparc64__ is
more appropriate to indicate a 64-bit environment.

mrg 8808c7e901 create the dhclient.leases file mode 600 for now as it may contain 
"media" lines that contain wireless network keys, that eg, ifconfig(8)
carefully hides.

this is not a complete solution, but it's OK until one arrives.
