Some protocols check sk_wmem_alloc value to determine if a timer must delay socket deallocation. We must take care of the sk_wmem_alloc value being one instead of zero when no write allocations are pending. Reported by Ingo Molnar, and full diagnostic from David Miller.

Miller, empty packet can be transmitted on connected socket for datagram protocols. However, this patch broke a high level application using ROSE network protocol with connected datagram. Bulletin Board Stations perform bulletins forwarding between BBS stations via ROSE network using a forward protocol. Now, if for some reason, a buffer in the application software happens to be empty at a specific moment, ROSE sends an empty packet via unfiltered packet socket. When received, this ROSE packet introduces perturbations of data exchange of BBS forwarding, for the application message forwarding protocol is waiting for something else. We agree that a more careful programming of the application protocol would avoid this situation and we are willing to debug it. But, as an empty frame is no use and does not have any meaning for ROSE protocol, we may consider filtering zero length data both when sending and receiving socket data. The proposed patch repaired BBS data exchange through ROSE network that were broken since 2.6.22.11 kernel. Signed-off-by: Bernard Pidoux <f6bvp@amsat.org> Signed-off-by: David S.

* netdev: Allocate multiple queues for TX.David S. Miller2008-07-171-2/+4
| | | | | | | | | | | | | | | | alloc_netdev_mq() now allocates an array of netdev_queue structures for TX, based upon the queue_count argument. Furthermore, all accesses to the TX queues are now vectored through the netdev_get_tx_queue() and netdev_for_each_tx_queue() interfaces. This makes it easy to grep the tree for all things that want to get to a TX queue of a net device. Problem spots which are not really multiqueue aware yet, and only work with one queue, can easily be spotted by grepping for all netdev_get_tx_queue() calls that pass in a zero index.

* rose: improving AX25 routing frames via ROSE networkBernard Pidoux2008-06-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ROSE network is organized through nodes connected via hamradio or Internet. AX25 packet radio frames sent to a remote ROSE address destination are routed through these nodes. Without the present patch, automatic routing mechanism did not work optimally due to an improper parameter checking. rose_get_neigh() function is called either by rose_connect() or by rose_route_frame(). In the case of a call from rose_connect(), f0 timer is checked to find if a connection is already pending. In that case it returns the address of the neighbour, or returns a NULL otherwise. When called by rose_route_frame() the purpose was to route a packet AX25 frame through an adjacent node given a destination rose address. However, in that case, t0 timer checked does not indicate if the adjacent node is actually connected even if the timer is not null. Thus, for each frame sent, the function often tried to start a new connexion even if the adjacent node was already connected. The patch adds a "new" parameter that is true when the function is called by rose route_frame(). This instructs rose_get_neigh() to check node parameter "restarted". If restarted is true it means that the route to the destination address is opened via a neighbour node already connected. If "restarted" is false the function returns a NULL. In that case the calling function will initiate a new connection as before. This results in a fast routing of frames, from nodes to nodes, until destination is reached, as originaly specified by ROSE protocole.

* [NET]: Make device event notification network namespace safeEric W. Biederman2007-10-101-0/+3
| | | | | | | | | | | | | | | | | | Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Make socket creation namespace safe.Eric W. Biederman2007-10-101-3/+6
| | | | | | | | | | | | | | | | | | | | | | | This patch passes in the namespace a new socket should be created in and has the socket code do the appropriate reference counting. By virtue of this all socket create methods are touched. In addition the socket create methods are modified so that they will fail if you attempt to create a socket in a non-default network namespace. Failing if we attempt to create a socket outside of the default network namespace ensures that as we incrementally make the network stack network namespace aware we will not export functionality that someone has not audited and made certain is network namespace safe. Allowing us to partially enable network namespaces before all of the exotic protocols are supported. Any protocol layers I have missed will fail to compile because I now pass an extra parameter into the socket creation code.

* [NET]: Make /proc/net per network namespaceEric W. Biederman2007-10-101-8/+9
| | | | | | | | | | | | | | | | | | This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

* [AX.25]: Fix unchecked ax25_listen_register usesRalf Baechle2006-12-171-1/+2
| | | | | | | | Fix ax25_listen_register to return something that's a sane error code, then all callers to use it. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [AX.25]: Fix unchecked ax25_protocol_register uses.Ralf Baechle2006-12-171-1/+6
| | | | | | | | | Replace ax25_protocol_register by ax25_register_pid which assumes the caller has done the memory allocation. This allows replacing the kmalloc allocations entirely by static allocations. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [ROSE] lockdep: fix false positiveRalf Baechle2006-07-121-0/+9
| | | | | | | | | | ROSE network devices are virtual network devices encapsulating ROSE frames into AX.25 which will be sent through an AX.25 device, so form a special "super class" of normal net devices; split their locks off into a separate class since they always nest.

* [AX.25]: Use kzallocRalf Baechle2006-07-091-2/+1
| | | | | | | Replace kzalloc instead of kmalloc + memset. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>
