Bug ID: 245319
Summary: mq_open does not honor its mode argument
Product: Base System
Version: 12.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: misc
Assignee: b...@freebsd.org
Reporter: i.n1...@programmer.net
Here is the code:
void openMsgQueue(void)
{
mode_t mode = S_IRUSR | S_IWUSR |
S_IRGRP | S_IWGRP |
S_IROTH | S_IWOTH;
struct mq_attr attributes;
bzero(&attributes, sizeof(attributes));
attributes.mq_maxmsg = 100;
attributes.mq_msgsize = MSG_MAX_SIZE;
mqid = mq_open(QUEUE_NAME, O_RDONLY | O_CREAT, mode, attributes);
if ((mqd_t) -1 == mqid)
{
err(1, "mq_open");
}
}
Obviously, MSG_MAX_SIZE and QUEUE_NAME are defined elsewhere.
After running this function for the first time, the QUEUE_NAME was created, but
the permissions on the queue were:
-rw-r--r--
Since I specified that every user should have "rw" access, but it didn't
happen, I had to use chmod so other users could send messages to this queue.
