This is a continuation from linux-audit/audit-userspace#57
It was reported that argc does not match argument count in the EXECVE record. For example:
type=EXECVE msg=audit(1469116325.662:1707): argc=2 a0="/bin/echo"

This can be looked for in existing logs with:

#!/usr/bin/env python2

import glob

files = glob.glob("/var/log/audit/*")

for fname in files:
    with open(fname, "r") as f:
            for line in f:
                if 'type=EXECVE' in line:
                    try:
                        # extract sub-string after argc=
                        substring = line.split("argc=",2)[1]
                        args=substring.partition(' ')[0]
                        actual_args = substring.count(' ')
                        if (int(args) != actual_args):
                            print line 
                    except:
                        print "Ran into an error: " + line

Problem seems to be related to empty arguments. This can be reproduced as follows:

autrace /bin/ls "" "/etc"
ausearch --start recent -m execve -i | grep EXECVE
type=EXECVE msg=audit(10/03/2018 13:04:03.208:1391) : argc=3 a0=/bin/ls a2=/etc

@rgbriggs Done. I believe I touched this code last, so I'm happy to look into this if you don't have time.

Empty executable arguments were being skipped when printing out the list
of arguments in an EXECVE record, making it appear they were somehow
lost.  Include empty arguments as an itemized empty string.

Reproducer:
	autrace /bin/ls "" "/etc"
	ausearch --start recent -m execve -i | grep EXECVE
	type=EXECVE msg=audit(10/03/2018 13:04:03.208:1391) : argc=3 a0=/bin/ls a2=/etc

With fix:
	type=EXECVE msg=audit(10/03/2018 21:51:38.290:194) : argc=3 a0=/bin/ls a1= a2=/etc
	type=EXECVE msg=audit(1538617898.290:194): argc=3 a0="/bin/ls" a1="" a2="/etc"

venomdev-kernel pushed a commit to venomdev-kernel/Venoom that referenced this issue Dec 2, 2019
[ Upstream commit ea956d8be91edc702a98b7fe1f9463e7ca8c42ab ]

Empty executable arguments were being skipped when printing out the list
of arguments in an EXECVE record, making it appear they were somehow
lost.  Include empty arguments as an itemized empty string.

Reproducer:
	autrace /bin/ls "" "/etc"
	ausearch --start recent -m execve -i | grep EXECVE
	type=EXECVE msg=audit(10/03/2018 13:04:03.208:1391) : argc=3 a0=/bin/ls a2=/etc

With fix:
	type=EXECVE msg=audit(10/03/2018 21:51:38.290:194) : argc=3 a0=/bin/ls a1= a2=/etc
	type=EXECVE msg=audit(1538617898.290:194): argc=3 a0="/bin/ls" a1="" a2="/etc"
