Date Issued: Mon Dec 6 09:17:08 1993
Release on Which Patch May Be Installed: 6.2
Release Which Corrects Problem: 7.1P
Related Patches: cx6.2-068
Related Modification Numbers: None
Related SARs: None
Problem Description:
This Patch supersedes patch ethernet6.2-004 which was never released.
1) The Ethernet driver problem occurs because the driver tries to maintain
the data buffer address as an even address. When an odd address
is found, the driver tries to write the first byte of data
to the end of the previous buffer. However, the driver
writes the data byte to another area of memory. If the memory
is outside of the address range, the kernel panics in the
ie_transmit routine. If the memory is within the
data buffers, the byte may overwrite a chain address. This
will cause the kernel to panic some time later when this
chain address (now corrupted) is accessed.
2) The ise was generating large number of underruns on systems with
global memory.
Resolution Description:
1) This patch resolves the problem by writing the data byte to
the proper place, thus not corrupting any data area, and
not accessing memory outside the addressable range.
2) The outbound data is now being double-buffered in local memory.

Problem Description:
When there is heavy frontplane activity, devices connected to
the Integraged Ethernet interface cannot open connections.
Resolution Description:
This patch permits the number of output messages queued at
the Integrated Ethernet, Interphase Eagle Ethernet, and
Interphase FDDI interfaces to be selected by the user, rather
than be limited to the default value of 50. This prevents the
dropping of messages which resulted in the inability to connect
to the Integrated Ethernet interface.

Possible Side Effects:
If the values chosen are too high, the queues may hold all the
mbufs in the system. This patch attempts to keep this from happening
by setting the number of mbufs to five (5) times the sizes chosen.

Problem Description:
1. When file sharing is used (mostly by PCs using the NightHawk as an NFS
server) rpc.lockd uses a hash function to index a table of sharing
records. This function can sometimes yield negative values, causing
rpc.lockd to coredump.
2. During the boot process, rpc.lockd implements a grace period during which
lockdaemon peers can re-acquire locks they held prior to the reboot.
During this period, kernel messages are acknowledged and kept in a cache,
but no action is taken on their behalf. At the end of the grace period,
rpc.lockd discards all kernel messages from its message cache. rpc.lockd
then gets confused and uses a stale pointer to send a reply back to the
last kernel message it received. This produces a message from rpc.lockd
on the system console (or the debug trace file):
rpc.lockd: unknown klm_reply proc(0)
A truncated reply is then sent to the kernel. The kernel then complains
on the system console with the following message:
lock-manager: RPC error: RPC: Can't decode result
Resolution Description:
1. Modify the hash function so the hash value is always non-negative.
2. Modify the code in rpc.lockd that discards messages from the cache so the
last kernel message pointer is cleared when that message is discarded.

Problem Description:
1. After installing patch nfs6.2-003, sync operations on
remote nfs filesystems will sometimes cause remote files to
be padded out to a filesystem block size boundary.
2. The system may deadlock/hang when a sync of the nfs filesystems
and an nfs write getblk() both try to obtain locks on
the same buffer lock and rnode table hash lock.
Resolution Description:
1. Modified the nfs_strategy() routine.
The code that reduces the write buffer byte count down to
the size of the file would only be done if the vnode lock
was owned by the caller.
In the case of sync operations, the vnode lock may not be
locked by the caller. In this case, the round down to the
end-of-file operation was being skipped. Unfortunately,
sync write operation byte counts tend to be set to blocksize,
which may sometimes write out beyond the end of file.
Therefore, for sync operations that do not own the vnode
lock, execute more cautious code that reduces the buffer
byte count down to the current end-of-file.
2. Changed the rflush() routine, which is used on sync() operations,
so that it releases the rnode table hash lock while flushing out
data of an rnode/vnode.

When file sharing is used, rpc.lockd uses a hash function to index a

values, causing rpc.lockd to coredump. This is the same problem that
patch nfs6.2-001 fixes (see problem 1 in the Problem Description for
this patch); however a different part of the code caused the negative
value in the hash function. This was seen from accessing a file from
a PowerUnix filesystem via NFS.

Resolution Description:
Changed rfs_setattr() to fill in the current time if it sees a request
with the tv_usec field set to 1000000. PowerUX systems create requests this
way but CX/UX systems do not, apparently because of a discrepancy in NFS

Problem Description:
When SATAN was run against a CX/UX system, it would cause
all sorts of problems, including a possible panic. It was
determined that this was occurring when a short packet was
sent to a port being serviced via RPC.
Resolution Description:
The problem was in the code which processes incoming
RPC service requests (which includes NFS requests).
All incoming requests are delivered to this routine in the
form of mbufs.
It is possible for a request to span multiple mbufs (ie: an mbuf
chain where part of the request is in the first mbuf, continues
into the second mbuf, and so on).
As illustrated below, this routine was checking if the current
mbuf had at least 4*sizeof(u_long) (or 16) bytes, and, if it
didn't, it would call m_pullup().
The purpose of m_pullup() is to traverse an mbuf chain and
"pull up" at least n (in this case 16) bytes from the front
of the chain into a new mbuf (it will then recreate the rest
of the mbuf chain as hanging off of that one, and free the old
first mbuf).
Here is the problem that the original coder missed:
When m_pullup() doesn't find at least n bytes,
it will call m_freem(m) (and return an error code).
Here is the code:
----------------------------------------------------------
if ((m->m_len < 4*sizeof(u_long)) &&
(m_pullup(m,4*sizeof(u_long)) == 0)) {
rsstat.rsbadlen++;
goto bad;
}
...
bad:
m_freem(m);
...
----------------------------------------------------------
We are properly checking the error code, but then we
were jumping down to "bad". "bad" would then call
m_freem() on m (whose value never changed to this
calling routine).
The end result was that when we couldn't pull up at least
16 bytes in the incoming request, we would wind up calling
m_freem() on the same chain twice. The first time would put
the chain on the free list. The second time was attempting to
put the chain that's already on the free list on to the free
list.
The end result was that somehow multiple references
to the same mbuf could be acquired, and 'funky' stats
(such as "-574958294/220 mbufs in use") would be
reported.
The fix was as simple as adding one line (see below).
if ((m->m_len < 4*sizeof(u_long)) &&
(m_pullup(m,4*sizeof(u_long)) == 0)) {
rsstat.rsbadlen++;
Insert m=0; /*Don't free -- m_pullup() does that*/
goto bad;
}
...
bad:
m_freem(m);
...
By setting 'm' to NULL when m_pullup() fails, the second m_freem()
(in bad) will not try to (nor will it be able to) free it again.

Problem Description:
(1) When using the automounter with a large map the automounter dies
and causes user shells in auto-mounted directories to freeze. The
problem has been traced to a pointer not getting reset in a loop
and eventually overwriting the stack for the process.
(2) Init process may hang doing an nfs sync. As a result, the operations
that init does such as spawning new terminal processes or removal of
orphaned zombie processes is not done.
Resolution Description:
(1) Added code to reset pointer in the loop.
(2) The hang was caused by a previous nfs operation. If the file was
truncated during the operation, it could leave pages locked forever.
Fix is to always release page locks even if a file is truncated.

a network interface. The tty device to be used by the SLIP network
interface must be on a HPS serial communications controller.
The TCP/IP daemon /usr/etc/tcpipd and the softclock interrupt daemon
/usr/etc/softclockd must be started prior to initiating connections
over the SLIP network interface.
In order to configure SLIP interfaces on a system the following
parameter must be added to the configuration file
options NSL=2
Where '2' is the number of SLIP interfaces to be configured.

Related Modification Numbers: None
Related SARs: None
Problem Description:
1. Patch cx6.2-038 modifies the initvector function and allows for
very long label names. Commands that use these functions must
be relinked.
2. The assurance system requires that Series 5000 kernel libraries
be listed in the TCB files.
3. The rlogin and telnet daemons do not cause all processes still
holding on to a pty to terminate. This violates CX/SX security
policies.
4. The telnet daemon fails to pass a TZ environment variable to
the login session, causing it to revert to GMT.
Resolution Description:
1. Relink the necessary commands.
2. Modify the TCB.net file to reflect the current filesystem
organization.
3. The telnet and rlogin daemons now kill all processes attached
to the tty and pty before exiting.
4. The telnet daemon now passes a copy of its TZ environment variable
to the login session.

Problem Description: The Series 4000 and 5000 try to match their
TCP/IP buffer sizes with the remote machine's sizes as given in
the remote machine's connection establishment handshake. If the
remote sends a size of zero, the Series 4000 and 5000 will set their
size to zero also. This keeps the remote machine from sending any
data to the Series 4000 and 5000.
Resolution Description: This patch checks for a size of zero
and will not let the buffer size be set to zero, but will
default to 32K.

Problem Description:
1. Network mbufs are not being correctly freed and cause a small
memory leak.
2. Inetd does not do auditing correctly.
3. Several mls library changes were made in patch cx6.1-061.
Consequently, the commands which use the mls library need
to be re-compiled with the new library. This patch contains
the new executables for the commands in the tcp_ip product
that use the mls library.
4. ICMP redirect packets are being improperly handled.
Resolution Description:
1. The mbufs are now freed in the correct place in the kernel.
2. A minor fix has been made to inetd for the auditing problem.
3. No source level changes have been made to any of these commands.
They are simply re-compilations.
4. Ensure the kernel route redirect routine, rtredirect(), is passed
properly initialized parameters from the ICMP input routine,
icmp_input().

1) Cyberguard product requires packet filtering code in the kernel.
2) Inetd did not properly initialize access vectors.
3) TCP and UDP should have a longer TTL (time to live) value.
Resolution Description:
1) Provide packet filtering in the kernel.
2) Correct use of access vectors in inetd.
3) Increase TCP_TTL and UDP_TTL.

Problem Description:
If a packet longer than 1500 bytes is sent to the ip layer, and the
ip layer breaks it into smaller packets, it is possible that a zero
size transmit buffer will be generated. If certain Ethernet drivers
attempt to send this zero-size buffer, the controller may hang.
Resolution Description:
After breaking up a message, check for trailing zero-length m-bufs
and delete them.

Problem Description: support for cyberguard
Resolution Description:
ifconfig has been updated to support the new cyberguard
product, and man pages have been updated. Entry points
have been added to networking code to support the cyberguard
product. TCP/IP sequence numbering has been modified so
it is more random, and therefore much more difficult to
take over existing connections.
(This was done for a recent CERT advisory).

Problem Description:
Patch tcp_ip6.2-015 introduced a bug that causes some remote shell
commands to hang up. The command(s) will execute on the remote machine,
produce the desired output/results, but the connection between the two machines
will not close. Control C will not always terminate the command but Control D
usually will. Examples of commands that will hang up are (sleep 1) and (ls -l)
on a large directory. Certain shell scripts will also hang up.
Resolution Description:
In patch tcp_ip6.2-015, code was added to the source file tcp_input.c
in the FIN_WAIT_1/FIN_WAIT_2 state acknowledgement processing to fix a problem
with NISSIN token ring boards. In the case of the FIN_WAIT_1 state, the
existing code was changed to only execute if such a board is in the system when,
in fact, the code should execute whether or not such a board is installed. To
correct the problem, the check for NISSIN boards was removed from FIN_WAIT_1
acknowledgement processing to allow the socket/connection to properly shut down.

Problem Description:
(1) Firewall product dynamic kernel rules would not timeout properly
thus wasting system network resources.
(2) Firewall product's Private Virtual Network was not able to function
correctly in tightly coupled mode.
(3) TCP connections in the FIN_WAIT_2 state would not timeout in a
reasonable time frame.
(4) Size changes to the tcpcb structure effected the network utility
netstat(1) which has knowledge of that structure's size since it
accesses the structure by reading from /dev/kmem directly.
(5) inetd(1M) would consume large amounts of CPU time on non-secure
systems.
(6) Size changes to the tcpcb structure effected archived object files
in the network kernel library lib_netinet.
Resolution Description:
(1) Modified ip_output.o to timeout all dynamic rules.
(2) Add modifications to the process control block logic in the in_pcb.o
file to permit correct firewall Private Virtual Network tightly
coupled mode operation.
(3) Modifications to the tcp_timer.o and tcp_input.o files now ensure
that TCP-based processes in the FIN_WAIT_2 state correctly timeout.
(4) Rebuilt netstat to include the new tcpcb structure and thus allow it
to learn about that structure's new size change.
(5) Corrections to the structure of secure/non-secure logic checks in the
inetd(1M) main driver will eliminate the CPU usage problems experienced
on non-secure systems. Enhancements to the inetd logic also detect
and prevent denial of service attacks via the inetd chargen/echo
components.
(6) Rebuilt the kernel lib_netinet object files tcp_debug.o, tcp_output.o,
tcp_subr.o, and tcp_usrreq.o to incorporate the modified tcpcb
structure.

Problem Description:
(1) The Trusted Computing Base (TCB) networking file, TCB.net, utilized
by the mkassure(1MS) assurance tape utility incorrectly referenced
the obsolete kernel library lib_hcxif.
(2) The named(1M) manual page incorrectly referenced CyberGuard-related
documentation.
(3) Networking ports were being incorrectly reused when booting a system
or during a port rollover.
(4) FTP daemon ftpd contains libmls.a library function which can cause
a potential memory leak.
(5) TCP fast retransmit algorithm can inadvertently modify the TCP
retransmit timer asynchronously.
Resolution Description:
(1) Remove lib_hcxif from the TCB.net file.
(2) Remove all references to the CyberGuard-related documentation.
(3) Update the kernel lport() function to correctly rollover the next
available port.
(4) Rebuild the ftpd daemon to incorporate the fixed libmls.a function
makecf() to prevent the potential memory leak.
(5) Add spin lock protection around the fast retransmit algorithm code
where the TCP retransmit timer is modified.

Related Patches: firewall2.1-001, cx6.2-132
Related Modification Numbers: None.
Related SARs: None.
Problem Description:
(1) Incorrect multithreading logic in the slow timer function caused
connections in the FIN_WAIT_2 state to take a much greater amount of
time to time out, causing a large number of connections to remain in a
semiclosed state in the system.
(2) The TCP stack's kernel input routine did not have any slow timeout
support for sweeping IP filter rule buckets for timed out entries.
(3) The ftpd(1M) daemon would send the FTP server's PASV reply message
"Listening on data connection (X.X.X.X.X.X)" where X.X.X.X.X.X reveals
the FTP server's IP address and listening port to the FTP client.
(4) etc/inetd.conf and etc/services needed to be updated to support the
new Gopher and X11 proxies of firewall 2.1.1.
Resolution Description:
(1) Fix the TCP slow timeout (500ms) timer logic to permit TCP
connections in the TCP FIN_WAIT_2 state to time out after 11 minutes as
per standard Berkeley-derived TCP network stack behavior.
(2) Add new logic to the TCP stack's kernel input routine to permit slow
timeout support for sweeping IP filter rule buckets for timed out
entries. This improves IP packet filtering performance and use of
system resources.
(3) The ftpd(1M) daemon has been modified in support of the security
enhancement for FTP PASV mode. This enhancement includes the
removal of the FTP server's PASV reply message.
(4) Add updates to existing etc/inetd.conf and etc/services.

rather than those less than the CLOSE_WAIT state. This will
permit the removal of HTTP-based connections in the LAST_ACK
state which previously would never be timed out.
Added support for a proxy communicating with a server running on
the firewall.
Added support for PASV data connection mode for ftp(1) .
The tcp_input fix prevents TCP from getting into a mode where
the send window is presumed to be zero.
When this was the case, one byte probe packets were sent
every retransmission.
The use of the high-water mark to determine
the window size was removed.
This fix corrected a problem with the WebTrack
software where large (100KB+) files would never completely transfer.
