I duplicated your tests here: [root@localhost ~]# auditctl -w /tmp/test -p wa -k watch [root@localhost ~]# echo "ppp" >> /tmp/test [root@localhost ~]# cat /tmp/test ppp [root@localhost ~]# ausearch --start recent -i -f /tmp/test ---- type=PATH msg=audit(06/02/2011 14:32:45.146:112) : item=0 name=/tmp/test inode=164740 dev=fd:01 mode=file,644 ouid=root ogid=root rdev=00:00 obj=unconfined_u:object_r:user_tmp_t:s0 type=CWD msg=audit(06/02/2011 14:32:45.146:112) : cwd=/root type=SYSCALL msg=audit(06/02/2011 14:32:45.146:112) : arch=x86_64 syscall=open success=yes exit=3 a0=1842830 a1=441 a2=1b6 a3=0 items=1 ppid=1298 pid=1304 auid=sgrubb uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=pts0 ses=1 comm=bash exe=/bin/bash subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=watch Admittedly I am on the 2.6.38.6 kernel. But I'm not seeing a regression. When you set the perms to "wa" that is only going to be opens for writing or changes to file attributes. So, the cat command will not trigger an event and that is why I only get 1 event. I am also on a 64 bit system, but I would think that didn't matter...unless we have a signed/unsigned comparison problem...what do you have for an inode on the /tmp/watch file? ls -i /tmp/watch should get it. -Steve
