HP-PB Token Ring Release Notes for HP-UX 11.0

Patches and Fixes for this Version (B.11.00.07)

Fix:

•The HP-PB Token Ring driver panics during reset state.

The HP-PB Token Ring driver tries to handle control command completion interrupts

during reset state and hence it panics.

The driver code has been modiﬁed to add a check for the reset state in the control

command completion path and return without handling any control command completion

interrupts during reset state.

Patch PHNE_20536:

•The HP-PB Token Ring driver may consume all of the available IOVRs in the

system.

The driver does not combine small requests into a large one, so when it gets a fragmented

I/O request with too many small fragments from the higher layer, it will try to map each of

the fragments separately. This will consume a large number of IOVRs.

The driver code has been modiﬁed to combine small fragments into a large request so it

does not consume too many IOVRs.

•The HP-PB Token Ring driver may show too many outbound errors/discards.

One of the internal driver data structures has insufﬁcient number of entries, causing the

driver to drop outbound packets.

The driver code has been modiﬁed to increase the number of entries in this data structure.

•The HP-PB Token Ring driver fails to rebind IP after cable reconnect.

The driver sends LINKUP and then goes through a reset cycle which can take as much as

35 seconds on cable reconnect. Since the application ﬁnds that the link is up, it sends bind

requests, however, they fail as the driver is still in reset state.

The driver code has been modiﬁed to send LINKUP only after reset completion.

Patch PHNE_18922:

•The system panics with a Data page fault when the HP-PB Token Ring driver is

present in the system.

The driver does not validate the memory range of a data structure before writing to it. This

leads to memory corruption and the system may panic.

HP-PB Token Ring Release Notes for HP-UX 11.0

Patches and Fixes for this Version (B.11.00.07)

The ﬁx is to perform the range check before accessing the data structure, therefore

preventing memory corruption and subsequent panic.

Patch PHNE_17355:

•The card can go into a hung state and an error message will be logged in the

‘/var/adm/syslog/syslog.log’ ﬁle.

A bug in the ﬁrmware can create a situation such that the ﬁrmware sends inbound frames

with the size larger than the conﬁgured MTU. However, the driver does not provide enough

buffers for DMA. The DMA hardware then gives an error which causes the card and driver

to go into a fatal error (hung) state.

The driver will now drop those packets that arrive with the larger size, thus preventing

the hung state. Indication of the dropped packets is logged in the NetTL log ﬁle.

•CISCO HSRP addresses cannot be reached.

The HP-PB Token Ring driver treats all of the functional addresses as multicast

addresses. This causes a concern if any system uses functional addresses as the primary

source address.

The driver now checks for IP multicast functional addresses and converts only those to

general multicast functional addresses. Other functional addresses are used without any

transformation.

•The system may panic when it is heavily loaded and memory is low.

The HP-PB Token Ring driver reuses a buffer chain even after it has been freed,

consequently, the card initially will appear to hang (no outbound is performed). When the

user tries to reset the hung interface card with the lanadmin command, the system will

panic due to a wrong memory access.

More robust checks have been implemented and proper cleanup is done whenever memory

is freed.

•System panics with Data page fault in the HP-PB Token Ring driver.

The HP-PB Token Ring driver writes to a wrong memory address which may lead to a

system panic.

The driver now validates the address range before using the memory address.

•The HP-PB Token Ring driver shows the wrong value for “Operational Status”

MIB object.

The HP-PB Token Ring driver does not set the “Operational Status” MIB object to “UP”

after the successful initialization of the driver/interface card. This leaves the value of this

object always to “DOWN” even if the card is functional.

HP-PB Token Ring Release Notes for HP-UX 11.0

Patches and Fixes for this Version (B.11.00.07)

The driver now marks the “Operational Status” as “UP” when driver initialization is

successfully completed.

•When the HP-PB Token Ring card is used with a Token ring card supporting

4500 MTU size, the network may hang.

Since the maximum size for the HP-PB Token Ring card is 4170, it will ignore incoming

packets of a size greater than 4170. Some vendor cards support 4500 as the maximum

MTU, therefore, the maximum MTU size for the HP-PB Token Ring card must be

increased.

The maximum MTU size for the HP-PB Token Ring card has been increased to the

standard 4500, and the default MTU is set to 4170. The user may increase this to 4500

using the lanadmin command.

•SAM gives an error when conﬁguring HP-PB Token Ring card.

The cause of this defect was incorrect syntax usage for a shell command in the

initialization script /usr/sbin/hptoken_init.

The syntax has been corrected.

Patch PHNE_15000:

•The IP multicast feature does not work.

In the token2_hw_req() ﬁle, the code to swap the MAC address before setting the

destination address to the functional address is not needed, since the driver gets the bits in

the right format from the upper layer.
