Move environment files from common/ to env/

2017-08-15T12:18:45+00:00

About a quarter of the files in common/ relate to the environment. It
seems better to put these into their own subdirectory and remove the
prefix.

env: avoid possible NULL pointer access

2017-05-12T12:37:17+00:00

env_attr_lookup call env_attr_walk with
callback = regex_callback.

In env_attr_walk
attributes = strchr(entry_cpy, ENV_ATTR_SEP)
will return NULL if ENV_ATTR_SEP is not found.

In the aftermath regex_callback may call
strlen(attributes)
with a NULL value which will lead to a failure.

The problem was indicated by scan-clam.

env: Allow env_attr_walk to pass a priv * to callback

2015-05-21T13:13:19+00:00

In some cases it can be helpful to have context in the callback about
the calling situation. This is needed for following patches.

env: Simplify the reverse_strstr() interface

2015-05-21T13:13:19+00:00

The logic to find the whole matching name was split needlessly between
the reverse_strstr function and its caller. Fully contain it to make the
interface for calling it more consistent.

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.
