f94b4eab06 Use strtoi(3) and strtou(3) from NetBSD-8 instead of the harder to use 
strtol(3) calls.
Add shims around strtoimax(3) and strtoumax(3) when these functions
are not available.

2360efb8cf Add qnx* to OS detection so we can pass the __EXT define and stay using 
--cstd=c99.

c6c54d9e96 Include linux/rtnetlink.h in config.h rather than each file that needs it. 
Detect RTM_NEWNEIGH rather than force a define based on __linux__.

cf2469a152 If we don't include sys/queue.h directly the clang analyzer complains 
about using freed memory.
That seems to be a workaround for this upstream bug:

e3159b9cc0 Align config.h contents better 2014-11-11 10:02:17 +00:00

bc09d81de2 TAILQ is now inlcuded via config.h either via sys/queue.h or compat/queue.h. 
This allows dhcpcd to compile on systems that do not even supply sys/queue.h,
such as the musl C library.

Thanks to Juan RP.

8f008ca7f5 Remove vis based encoding - instead expand the DHCP option encoding to a 
natural string based on content except as noted:
  *  domain (RFC3397)/dname (string) is strict domain name allowance
     (ie, [alnum] with _- (but not at the start or end))
  *  string is now printable ascii (1-127) until invalid
  *  ascii is all ascii (1-127) until invalid
  *  raw is all chars (1-255) until NUL
  *  binhex is a hex representation of the option including embedded NULs
  *  ssid is still escpaed octal because it's expected to be human readable
     AND can technically be all NUL
  *  everything else has strict option -> value encoding

This removes all shell escaped encoding - dhcpcd will assume that IF the
--script option is a shell, it will quote variables correctly.
The stock dhcpcd-run-hooks does.

dhcpcd -V now prints how the variables will be decoded.

Changed some options in dhcpcd-definitions.conf to more sensible defaults.

5b0c4877d5 We only supply svis(3) so rename the files as such. 2014-09-27 00:12:21 +00:00

c7d3d69b81 Clean up configure _vis files 2014-09-26 23:20:35 +00:00
Roy Marples
4f2199843d Sanitise the following characters using svis(3) with VIS_CTYLE and VIS_OCTAL: 
| ^ & ; < > ( ) $ ` \ " ' <tab> <newline>
This allows a non buggy unvis(1) to decode it 100% and stays compatible with
how dhcpcd used to handle encoding on most platforms.
For systems that supply svis(3) there is a code reduction, for systems that
do not, a slight code increase.

This change mitigates systems affected by bash CVE-2014-6271 and CVE-2014-7169.

f7d83c0dfc It's possible to configure a Linux kernel with nl80211 where the 
SSID won't be reported, but is available via WEXT.
This is very silly, but dhcpcd still needs to work.
Thus enable both protocols and use nl80211 if WEXT fails.

ffb70eff16 Fix arc4random_uniform test. 
Rename if-linux-wireless.c to if-linux-wext.c to better reflect it's purpose.
 2014-09-10 02:22:18 +00:00
Roy Marples
67ed6c5fdc Use the nl80211 interface on Linux to get the wireless SSID. 
If this is not found in the system headers, fall back to assuming WEXT.
This has been done because the WEXT module has been marked as deprecated
for a while now and I'm getting bored of people asking me why their
wireless wasn't working. Bloated dhcpcd by another 600 bytes as a result.

01890c79df Split arc4random_uniform into it's own compat function and add 
it's proper copyright.
Add a new test for it to configure so that we can use the
uclibc arc4random function and our compat arc4random_uniform function.
