2007-10-10[DCCP]: Rate-limit DCCP-SyncsGerrit Renker
This implements a SHOULD from RFC 4340, 7.5.4: "To protect against denial-of-service attacks, DCCP implementations SHOULD impose a rate limit on DCCP-Syncs sent in response to sequence-invalid packets, such as not more than eight DCCP-Syncs per second." The rate-limit is maintained on a per-socket basis. This is a more stringent policy than enforcing the rate-limit on a per-source-address basis and protects against attacks with forged source addresses. Moreover, the mechanism is deliberately kept simple. In contrast to xrlim_allow(), bursts of Sync packets in reply to sequence-invalid packets are not supported. This foils such attacks where the receipt of a Sync triggers further sequence-invalid packets. (I have tested this mechanism against xrlim_allow algorithm for Syncs, permitting bursts just increases the problems.) In order to keep flexibility, the timeout parameter can be set via sysctl; and the whole mechanism can even be disabled (which is however not recommended). The algorithm in this patch has been improved with regard to wrapping issues thanks to a suggestion by Arnaldo. Commiter note: Rate limited the step 6 DCCP_WARN too, as it says we're sending a sync.

2007-10-10Device tree aware EMAC driverDavid Gibson
Based on BenH's earlier work, this is a new version of the EMAC driver for the built-in ethernet found on PowerPC 4xx embedded CPUs. The same ASIC is also found in the Axon bridge chip. This new version is designed to work in the arch/powerpc tree, using the device tree to probe the device, rather than the old and ugly arch/ppc OCP layer. This driver is designed to sit alongside the old driver (that lies in drivers/net/ibm_emac and this one in drivers/net/ibm_newemac). The old driver is left in place to support arch/ppc until arch/ppc itself reaches its final demise (not too long now, with luck). This driver still has a number of things that could do with cleaning up, but I think they can be fixed up after merging. Specifically: - Should be adjusted to properly use the dma mapping API. Axon needs this. - Probe logic needs reworking, in conjuction with the general probing code for of_platform devices. The dependencies here between EMAC, MAL, ZMII etc. make this complicated. At present, it usually works, because we initialize and register the sub-drivers before the EMAC driver itself, and (being in driver code) runs after the devices themselves have been instantiated from the device tree.

2007-10-10[NET] netconsole: Support dynamic reconfiguration using configfsSatyam Sharma
Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>. This patch introduces support for dynamic reconfiguration (adding, removing and/or modifying parameters of netconsole targets at runtime) using a userspace interface exported via configfs. Documentation is also updated accordingly. Issues and brief design overview: (1) Kernel-initiated creation / destruction of kernel objects is not possible with configfs -- the lifetimes of the "config items" is managed exclusively from userspace. But netconsole must support boot/module params too, and these are parsed in kernel and hence netpolls must be setup from the kernel. Joel Becker suggested to separately manage the lifetimes of the two kinds of netconsole_target objects -- those created via configfs mkdir(2) from userspace and those specified from the boot/module option string. This adds complexity and some redundancy here and also means that boot/module param-created targets are not exposed through the configfs namespace (and hence cannot be updated / destroyed dynamically). However, this saves us from locking / refcounting complexities that would need to be introduced in configfs to support kernel-initiated item creation / destroy there. (2) In configfs, item creation takes place in the call chain of the mkdir(2) syscall in the driver subsystem. If we used an ioctl(2) to create / destroy objects from userspace, the special userspace program is able to fill out the structure to be passed into the ioctl and hence specify attributes such as local interface that are required at the time we set up the netpoll. For configfs, this information is not available at the time of mkdir(2). So, we keep all newly-created targets (via configfs) disabled by default. The user is expected to set various attributes appropriately (including the local network interface if required) and then write(2) "1" to the "enabled" attribute. Thus, netpoll_setup() is then called on the set parameters in the context of _this_ write(2) on the "enabled" attribute itself. This design enables the user to reconfigure existing netconsole targets at runtime to be attached to newly-come-up interfaces that may not have existed when netconsole was loaded or when the targets were actually created. All this effectively enables us to get rid of custom ioctls. (3) Ultra-paranoid configfs attribute show() and store() operations, with sanity and input range checking, using only safe string primitives, and compliant with the recommendations in Documentation/filesystems/sysfs.txt. (4) A new function netpoll_print_options() is created in the netpoll API, that just prints out the configured parameters for a netpoll structure. netpoll_parse_options() is modified to use that and it is also exported to be used from netconsole.

2007-10-10[NET] netconsole: Support multiple logging targetsSatyam Sharma
Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>. This patch introduces support for multiple targets, independent of CONFIG_NETCONSOLE_DYNAMIC -- this is useful even in the default case and (including the infrastructure introduced in previous patches) doesn't really add too many bytes to module text. All the complexity (and size) comes with the dynamic reconfigurability / userspace interface patch, and so it's plausible users may want to keep this enabled but that disabled (say to avoid a dependency on CONFIG_CONFIGFS_FS too). Also update documentation to mention the use of ";" separator to specify multiple logging targets in the boot/module option string. Brief overview: We maintain a target_list (and corresponding lock). Get rid of the static "default_target" and introduce allocation and release functions for our netconsole_target objects (but keeping sure to preserve previous behaviour such as default values). During init_netconsole(), ";" is used as the separator to identify multiple target specifications in the boot/module option string. The target specifications are parsed and netpolls setup. During exit, the target_list is torn down and all items released.

2007-10-10[NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger
Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted.

Add support for setting the P_Key index of sent MADs and getting the P_Key index of received MADs. This requires a change to the layout of the ABI structure struct ib_user_mad_hdr, so to avoid breaking compatibility, we default to the old (unchanged) ABI and add a new ioctl IB_USER_MAD_ENABLE_PKEY that allows applications that are aware of the new ABI to opt into using it. We plan on switching to the new ABI by default in a year or so, and this patch adds a warning that is printed when an application uses the old ABI, to push people towards converting to the new ABI.

2007-10-04[POWERPC] cpm: Describe multi-user ram in its own device node.Scott Wood
The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.

2007-10-04[POWERPC] Document local bus nodes in the device tree, and update cuboot-pq2.Scott Wood
The localbus node is used to describe devices that are connected via a chip select or similar mechanism. The advantages over placing the devices under the root node are that it can be probed without probing other random things under the root, and that the description of which chip select a given device uses can be used to set up mappings if the firmware failed to do so in a useful manner. cuboot-pq2 is updated to match the binding; previously, it called itself chipselect rather than localbus, and used phandle linkage between the actual bus node and the control node (the current agreement is to simply use the fully-qualified address of the control registers, and ignore the overlap with the IMMR node).

2007-10-03[POWERPC] Introduce new CPM device bindings.Scott Wood
This introduces a new device binding for the CPM and other devices on these boards. Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

2007-09-20Fix CRLF line endings in Documentation/input/iforce-protocol.txtLinus Torvalds
Emil Medve points out that this documentation file uses CRLF line endings, which means that if you use [core] autocrlf=input (which makes sense if you ever develop under Windows, for example, or if you use other broken tools) in your git config, git will always complain about the file being dirty. This removes the bogus DOS line endings, and removes whitespace at the end of line. Cc: Emil Medve <Emilian.Medve@Freescale.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
