* [DCCP]: Check if already in the CLOSING state in dccp_rcv_closereqArnaldo Carvalho de Melo2005-09-13
| | | | | | | | It is possible to receive more than one CLOSEREQ packet if the CLOSE packet sent in response is somehow lost, change the state to DCCP_CLOSING only on the first CLOSEREQ packet received. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

* [NETROM]: Implement G8PZT Circuit reset for NET/ROMRalf Baechle2005-09-12
| | | | | | | | | | | | | | | | | NET/ROM is lacking a connection reset like TCP's RST flag which at times may result in a connecting having to slowly timing out instead of just being reset. An earlier attempt to reset the connection by sending a NR_CONNACK | NR_CHOKE_FLAG transport was inacceptable as it did result in crashes of BPQ systems. An alternative approach of introducing a new transport type 7 (NR_RESET) has be implemented several years ago in Paula Jayne Dowie G8PZT's Xrouter. Implement NR_RESET for Linux's NET/ROM but like any messing with the state engine consider this experimental for now and thus control it by a sysctl (net.netrom.reset) which for the time being defaults to off.

* [NETROM]: Fix rebuild header messRalf Baechle2005-09-12

* [NET]: Add netlink connector.Evgeniy Polyakov2005-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel connector - new userspace <-> kernel space easy to use communication module which implements easy to use bidirectional message bus using netlink as it's backend. Connector was created to eliminate complex skb handling both in send and receive message bus direction. Connector driver adds possibility to connect various agents using as one of it's backends netlink based network. One must register callback and identifier. When driver receives special netlink message with appropriate identifier, appropriate callback will be called. From the userspace point of view it's quite straightforward: socket(); bind(); send(); recv(); But if kernelspace want to use full power of such connections, driver writer must create special sockets, must know about struct sk_buff handling... Connector allows any kernelspace agents to use netlink based networking for inter-process communication in a significantly easier way: int cn_add_callback(struct cb_id *id, char *name, void (*callback) (void *)); void cn_netlink_send(struct cn_msg *msg, u32 __groups, int gfp_mask); struct cb_id { __u32 idx; __u32 val; }; idx and val are unique identifiers which must be registered in connector.h for in-kernel usage. void (*callback) (void *) - is a callback function which will be called when message with above idx.val will be received by connector core. Using connector completely hides low-level transport layer from it's users. Connector uses new netlink ability to have many groups in one socket.

The problem is that the number of bits for the virtual linear array short-format VHPT (Virtually mapped linear page table, VMLPT for short) is being tested incorrectly. There are two problems: 1. The PAL call that should tell the kernel the size of the virtual address space isn't implemented for the simulator, so the kernel uses the default 50. This is addressed separately in dc90e95f310f4f821c905b2aec8e9449bb3270fa 2. In arch/ia64/mm/init.c there's code to calcualte the size of the VMLPT based on the number of implemented virtual address bits and the page size. It checks to see if the VMLPT base address overlaps the top of the mapped region, but this check doesn't allow for the address space hole, and in fact will never trigger. Here's an alternative test and panic, that I think is more accurate. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of the change. Use per cpu MCA/INIT stacks. Change the SAL to OS state (sos) to be per process. Do all the assembler work on the MCA/INIT stacks, leaving the original stack alone. Pass per cpu state data to the C handlers for MCA and INIT, which also means changing the mca_drv interfaces slightly.

| * | [IA64] MCA/INIT: avoid reading INIT record during INIT eventKeith Owens2005-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading the INIT record from SAL during the INIT event has proved to be unreliable, and a source of hangs during INIT processing. The new MCA/INIT handlers remove the need to get the INIT record from SAL. Change salinfo.c so mca.c can just flag that a new record is available, without having to read the record during INIT processing. This patch can be applied without the new MCA/INIT handlers. Also clean up some usage of NR_CPUS which should have been using cpu_online(). Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the CM REQ handling function gets to error2, then it frees cm_id_priv->timewait_info. But the next line goes through ib_destroy_cm_id() -> ib_send_cm_rej() -> cm_reset_to_idle(), which ends up calling cm_cleanup_timewait(), which dereferences the pointer we just freed.

We do this by sweeping the event lists before returning from a destroy calls, and then return the number of events already reported before the destroy call. This allows userspace wait until it has processed all events for an object returned from the kernel before it frees its context for the object. The ABI of the destroy CQ, destroy QP and destroy SRQ commands has to change to return the event count, so bump the ABI version from 1 to 2. The userspace libibverbs library has already been updated to handle both the old and new ABI versions. Signed-off-by: Roland Dreier <rolandd@cisco.com>
