7bbdaefc7f checkseapp: generalize input validation
Input validation was hard-coded into a validation routine
that would check against type and key names in a scattered,
order dependent conditional code block.

This makes it harder than it should be to add new key value
pairs and types into checkseapp.

To correct this, we add a validation callback into the
static mapping. If the validation callback is set, the
existing validation routine will call this for input
validation. On failure, a validation specific error message
is returned to be displayed.

922b4e9522 checkfc: do not die on 0 length fc's
Checkfc was treating 0 size fc files as a fatal error.
An empty fc file should be treated as "nothing to check"
so long as the -e option is passed.

We add this option, so we don't allow empty file_context
files to pass CTS checking.

ad3cb39e54 checkfc: add attribute test
Enable checkfc to check *_contexts against a set of valid attributes
which must be associated with all types in the contexts file that
is being checked.

Since it's imperative that checkfc knows which file its checking to
choose the proper attribute set, the -s option is introduced to
indicate the service_contexts file. The property_contexts file continues
to use the existing -p and file_contexts requires no specification, aka
it's the default.

Failure examples:
file_contexts:
Error: type "init" is not of set: "fs_type, dev_type, file_type"

service_contexts:
Error: type "init_exec" is not of set: "service_manager_type"

property_contexts:
Error: type "bluetooth_service" is not of set: "property_type"

81e1f90cd1 check_seapp: add support for "neverallow" checks
Introduce "neverallow" rules for seapp_contexts. A neverallow rule is
similar to the existing key-value-pair entries but the line begins
with "neverallow". A neverallow violation is detected when all keys,
both inputs and outputs are matched. The neverallow rules value
parameter (not the key) can contain regular expressions to assist in
matching. Neverallow rules are never output to the generated
seapp_contexts file.

Also, unless -o is specified, checkseapp runs in silent mode and
outputs nothing. Specifying - as an argument to -o outputs to stdout.

Sample Output:
Error: Rule in File "external/sepolicy/seapp_contexts" on line 87: "user=fake domain=system_app type=app_data_file" violates neverallow in File "external/sepolicy/seapp_contexts" on line 57: "user=((?!system).)* domain=system_app"

7d65b547d3 check_seapp: mac build memory leak
rule_map_free() took as a parameter a boolean menu rule_map_switch
that was used to determine if it should free the key pointer that
is also in the table. On GLIBC variants, calls to hdestroy do not
free the key pointer, on NON-GLIBC variants, it does. The original
patch was meant to correct this, however, it always passes "destroy"
as the rule_map_switch. On GLIBC variants this is fine, however on
NON-GLIBC variants, that free was compiled out, and the free() was
handled by hdestroy. In cases of failure where the rule_map was not
in the htable, those key's were not properly free'd.

773d412665 check_seapp: Correct output on duplicate entries
If a duplicate entry is found, rule_map_cmp() incorrectly
assumes that the lengths of the key value pairs should be
equal, when this is not true. The duplicate detection is
done on the input parameters, thus the lengths can be
different. This resulted in a duplicate error string
message of "do not match", instead of "match on all inputs".

Also, the file name printed that contained the error was
the output file, not the input file that contained it.

a5113a1500 Don't use address sanitizer for selinux tools.
Address sanitizer requires using libc++ (apparently). We removed
libc++ from these projects since they were C and the SDK/CTS was not
able to find libc++.

If we're interested in continuing to use ASAN on these tools
(probably), we should turn libc++ back on once we're sure CTS won't
die.

SELinux policy booleans are prohibited in AOSP, so we can drop the
support for the sebool= input selector.

534fb0711d checkseapp: Detect duplicate keys in seapp_contexts entries.
Presently it ignores duplicate keys in seapp_contexts entries, e.g.
if you were to specify:

user=system seinfo=platform user=bluetooth domain=system_app type=system_app_data_file

checkseapp would ignore the duplicate and libselinux would end up using
the last value defined for the key in each line.

0b820042e4 checkseapp: Detect duplicate entries within seapp_contexts.
Presently it only detects complete duplicates if you specify -s (strict),
which is not used in the external/sepolicy Makefile, and it allows
overriding earlier entries that have the same input selectors (e.g.
user=, seinfo=) with different values for the output selectors (e.g.
domain=, type=).  Thus, a device/<vendor>/<board>/sepolicy/seapp_contexts
file can override the external/sepolicy definitions, and even a single
seapp_contexts file can contain duplicated or conflicting definitions.

Make it always check strictly, and prohibit either duplicates on the
input selectors (i.e. overrides) or complete duplicates (redundant).
