11 years agonet/rxrpc: Use an IS_ERR test rather than a NULL test
Julien Brunel [Wed, 13 Aug 2008 09:40:48 +0000]
net/rxrpc: Use an IS_ERR test rather than a NULL test

In case of error, the function rxrpc_get_transport returns an ERR
pointer, but never returns a NULL pointer. So after a call to this
function, a NULL test should be replaced by an IS_ERR test.

A simplified version of the semantic patch that makes this change is
as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@correct_null_test@
expression x,E;
statement S1, S2;
@@
x =  rxrpc_get_transport(...)
<... when != x = E
if (
(
- x@p2 != NULL
+ ! IS_ERR ( x )
|
- x@p2 == NULL
+ IS_ERR( x )
)
 )
S1
else S2
...>
? x = E;
// </smpl>

pkt_sched: Add queue stopped test back to qdisc_run().

Based upon a bug report by Andrew Gallatin on netdev
with subject "CPU utilization increased in 2.6.27rc"

In commit 37437bb2e1ae8af470dfcd5b4ff454110894ccaf
("pkt_sched: Schedule qdiscs instead of netdev_queue.")
the test of the queue being stopped was erroneously
removed from qdisc_run().

When the TX queue of the device fills up, this omission
causes lots of extraneous useless work to be queued up
to softirq context, where we'll just return immediately
because the device is still stuffed up.

There's no reason for dynamically allocating an estimator object for every

switch to using the kernel-provided list implementation. This makes the code
much simpler and faster, as we do not need to traverse the list of all
estimators to find the one belonging to a stats object. There's no need to use
an rwlock, as we only have one reader. Also reorder the members of the
estimator structure slightly to avoid padding overhead. This can't be done
with the stats object as the members are currently copied to our user space
object via memcpy() and changing it would break ABI.

Sofar far pktgen have had a restriction to only use one device per kernel

The patch below is an effort to remove this by in pktgen configuration
adding a tag to  the device name a la eth0@0 etc. The tag is used for
usual device config just as before. Also a new flag is introduced to mirror
queue_map with sending threads smp_processor_id() QUEUE_MAP_CPU.

An example: We use 4 CPU's to send to one 10g interface (eth0)
 and we use the new tagging to send a mix of packet sizes, 64, 576 and

bonding: Don't destroy bonding master when removing slave via sysfs

It is wrong to destroy a bonding master from a context that uses the sysfs
of that bond. When last IPoIB slave is unenslaved from by writing to a
sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves)
the driver tries to destroy the bond. This is wrong and can lead to a
lockup or a crash.  This fix lets the bonding master stay and relies on
the user to destroy the bonding master if necessary (i.e. before module
ib_ipoib is unloaded)

atl1: deal with hardware rx checksum bug

The L1 hardware contains a bug that flags a fragmented IP packet
as having an incorrect TCP/UDP checksum, even though the packet
is perfectly valid and its checksum is correct.  There's no way to
distinguish between one of these good packets and a packet that
actually contains a TCP/UDP checksum error, so all we can do is
allow the packet to be handed up to the higher layers and let it
be sorted out there.

Add a comment describing this condition and remove the code that
currently fails to handle what may or may not be a checksum error.
