(Dropped the infiniband part, because Tetsuo modified the related code, I will send a separate patch for it once this is accepted.) This patch introduces /proc/sys/net/ipv4/ip_local_reserved_ports which allows users to reserve ports for third-party applications. The reserved ports will not be used by automatic port assignments (e.g. when calling connect() or bind() with port number 0). Explicit port allocation behavior is unchanged. Signed-off-by:

The new function can be used to read/write large bitmaps via /proc. A comma separated range format is used for compact output and input (e.g. 1,3-4,10-10). Writing into the file will first reset the bitmap then update it based on the given input. Signed-off-by:

(Based on Octavian's work, and I modified a lot.) As we are about to add another integer handling proc function a little bit of cleanup is in order: add a few helper functions to improve code readability and decrease code duplication. In the process a bug is also fixed: if the user specifies a number with more then 20 digits it will be interpreted as two integers (e.g. 10000...13 will be interpreted as 100.... and 13). Behavior for EFAULT handling was changed as well. Previous to this patch, when an EFAULT error occurred in the middle of a write operation, although some of the elements were set, that was not acknowledged to the user (by shorting the write and returning the number of bytes accepted). EFAULT is now treated just like any other errors by acknowledging the amount of bytes accepted. Signed-off-by:

Links for each port are created in sysfs using the device name, but this could be changed after being added to the bridge. As well as being unable to remove interfaces after this occurs (because userspace tools don't recognise the new name, and the kernel won't recognise the old name), adding another interface with the old name to the bridge will cause an error trying to create the sysfs link. This fixes the problem by listening for NETDEV_CHANGENAME notifications and renaming the link. https://bugzilla.kernel.org/show_bug.cgi?id=12743Signed-off-by:

Some RNDIS devices don't respond on the control channel until polled on the status channel. In particular, this was reported to be the case for the 2Wire HomePortal 1000SW. This is roughly based on a patch by John Carr <john.carr@unrouted.co.uk> which is reported to be needed for use with some Windows Mobile devices and which is currently applied by Mandriva.

Allocating memory can fail, and since we have the memory we need in sky2_resume when sky2_suspend is called, just stop the hardware without freeing the memory it's using. This avoids the possibility of failing because we can't allocate memory in sky2_resume(), and allows sharing code with sky2_restart(). Signed-off-by:

netif_stop_queue does not ensure all in-progress transmits are complete, so use netif_tx_disable() instead. Secondly, make sure NAPI polls are disabled before stopping the tx queue, otherwise sky2_status_intr might trigger a TX queue wakeup between when we stop the queue and NAPI is disabled.

There appears to be an off-by-1 defect in the maximum packet size copied when copybreak is speified in these modules. The copybreak module params are specified as: "Maximum size of packet that is copied to a new buffer on receive" The tests are changed from "< copybreak" to "<= copybreak" and moved into new static functions for readability.

When adding more than 14 mac-vlan adapters on e1000 the driver would fire a WARN_ON when adding the 15th. The WARN_ON in this case is completely un-necessary, as the code below the WARN_ON is directly handling the value the WARN_ON triggered on. CC: Jiri Pirko <jpirko@redhat.com> Signed-off-by:

This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.

We can't use zero magic "bad" value to check if IXGBE_RSC_CB(skb)->dma is valid. It is only valid in x86/arm/m68k/alpha architectures and in spark, powerPC and other architectures it should be ~0.
