fw_env: fix incorrect usage of open(O_CREAT)

2012-12-19T22:51:57+00:00

When using open(), the O_CREAT flag must be given a mode, otherwise it
uses random garbage from the stack.  Also, it can fail to build:

In file included from /usr/include/fcntl.h:290:0,
                 from fw_env_main.c:42:
In function 'open',
    inlined from 'main' at fw_env_main.c:97:9:
/usr/include/bits/fcntl2.h:50:24: error: call to '__open_missing_mode' declared
	with attribute error: open with O_CREAT in second argument needs 3 arguments

fw_env: fix type of len

2012-12-19T22:51:57+00:00

This variable is assigned by a size_t, and is printed that way, but is
incorrectly declared as an int.  Which means we get warnings:
fw_env.c: In function 'fw_setenv':
fw_env.c:409:5: warning: format '%zu' expects argument of type 'size_t',
	but argument 3 has type 'int' [-Wformat]

Use the variable access flags to implement the protection for ethaddr
and serial# instead of hard-coding them.

tools/env: Add environment variable flags support

2012-12-13T18:46:56+00:00

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.  Call
env_acl_validate_setenv_params() from setenv() in fw_env.c.

If the entry is not found in the env .flags, then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

Need to build in _ctype for isdigit for Linux.
