* [CRYPTO] Add alignmask for low-level cipher implementationsHerbert Xu2005-07-06
| | | | | | | | | | | | | | | | | | | The VIA Padlock device requires the input and output buffers to be aligned on 16-byte boundaries. This patch adds the alignmask attribute for low-level cipher implementations to indicate their alignment requirements. The mid-level crypt() function will copy the input/output buffers if they are not aligned correctly before they are passed to the low-level implementation. Strictly speaking, some of the software implementations require the buffers to be aligned on 4-byte boundaries as they do 32-bit loads. However, it is not clear whether it is better to copy the buffers or pay the penalty for unaligned loads/stores. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [CRYPTO] Add support for low-level multi-block operationsHerbert Xu2005-07-06
| | | | | | | | | | | | | This patch adds hooks for cipher algorithms to implement multi-block ECB/CBC operations directly. This is expected to provide significant performance boots to the VIA Padlock. It could also be used for improving software implementations such as AES where operating on multiple blocks at a time may enable certain optimisations.

* [PATCH] ppc32: add Freescale MPC885ADS board supportAndrei Konovalov2005-07-05
| | | | | | | | | | | | | | | | | | This patch adds the Freescale MPC86xADS board support. The supported devices are SMC UART and 10Mbit ethernet on SCC1. The manual for the board says that it "is compatible with the MPC8xxFADS for software point of view". That's why this patch extends FADS instead of introducing a new platform. FEC is not supported as the "combined FCC/FEC ethernet driver" driver by Pantelis Antoniou should replace the current FEC driver.

| * [TCP]: Move to new TSO segmenting scheme.David S. Miller2005-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make TSO segment transmit size decisions at send time not earlier. The basic scheme is that we try to build as large a TSO frame as possible when pulling in the user data, but the size of the TSO frame output to the card is determined at transmit time. This is guided by tp->xmit_size_goal. It is always set to a multiple of MSS and tells sendmsg/sendpage how large an SKB to try and build. Later, tcp_write_xmit() and tcp_push_one() chop up the packet if necessary and conditions warrant. These routines can also decide to "defer" in order to wait for more ACKs to arrive and thus allow larger TSO frames to be emitted. A general observation is that TSO elongates the pipe, thus requiring a larger congestion window and larger buffering especially at the sender side. Therefore, it is important that applications 1) get a large enough socket send buffer (this is accomplished by our dynamic send buffer expansion code) 2) do large enough writes.

| * [TCP]: Fix __tcp_push_pending_frames() 'nonagle' handling.David S. Miller2005-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'nonagle' should be passed to the tcp_snd_test() function as 'TCP_NAGLE_PUSH' if we are checking an SKB not at the tail of the write_queue. This is because Nagle does not apply to such frames since we cannot possibly tack more data onto them. However, while doing this __tcp_push_pending_frames() makes all of the packets in the write_queue use this modified 'nonagle' value. Fix the bug and simplify this function by just calling tcp_write_xmit() directly if sk_send_head is non-NULL. As a result, we can now make tcp_data_snd_check() just call tcp_push_pending_frames() instead of the specialized __tcp_data_snd_check(). Signed-off-by: David S. Miller <davem@davemloft.net>
| * [TCP]: Fix redundant calculations of tcp_current_mss()David S. Miller2005-07-05
| | | | | | | | | | | | | | | | | | | | | | tcp_write_xmit() uses tcp_current_mss(), but some of it's callers, namely __tcp_push_pending_frames(), already has this value available already. While we're here, fix the "cur_mss" argument to be "unsigned int" instead of plain "unsigned". Signed-off-by: David S. Miller <davem@davemloft.net>
| * [TCP]: Kill extra cwnd validate in __tcp_push_pending_frames().David S. Miller2005-07-05
| | | | | | | | | | | | | | | | | | | | | | The tcp_cwnd_validate() function should only be invoked if we actually send some frames, yet __tcp_push_pending_frames() will always invoke it. tcp_write_xmit() does the call for us, so the call here can simply be removed. Also, tcp_write_xmit() can be marked static. Signed-off-by: David S. Miller <davem@davemloft.net>
| * [TCP]: Move __tcp_data_snd_check into tcp_output.cDavid S. Miller2005-07-05

| * [TCP]: Move send test logic out of net/tcp.hDavid S. Miller2005-07-05
| | | | | | | | | | | | | | | | | | | | | | | | This just moves the code into tcp_output.c, no code logic changes are made by this patch. Using this as a baseline, we can begin to untangle the mess of comparisons for the Nagle test et al. We will also be able to reduce all of the redundant computation that occurs when outputting data packets. Signed-off-by: David S. Miller <davem@davemloft.net>
| * [TCP]: Fix quick-ack decrementing with TSO.David S. Miller2005-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On each packet output, we call tcp_dec_quickack_mode() if the ACK flag is set. It drops tp->ack.quick until it hits zero, at which time we deflate the ATO value. When doing TSO, we are emitting multiple packets with ACK set, so we should decrement tp->ack.quick that many segments. Note that, unlike this case, tcp_enter_cwr() should not take the tcp_skb_pcount(skb) into consideration. That function, one time, readjusts tp->snd_cwnd and moves into TCP_CA_CWR state.

| * [TCP]: Simplify SKB data portion allocation with NETIF_F_SG.David S. Miller2005-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ideal and most optimal layout for an SKB when doing scatter-gather is to put all the headers at skb->data, and all the user data in the page array. This makes SKB splitting and combining extremely simple, especially before a packet goes onto the wire the first time. So, when sk_stream_alloc_pskb() is given a zero size, make sure there is no skb_tailroom(). This is achieved by applying SKB_DATA_ALIGN() to the header length used here. Next, make select_size() in TCP output segmentation use a length of zero when NETIF_F_SG is true on the outgoing interface. Signed-off-by: David S. Miller <davem@davemloft.net>

I couldn't trigger a crash on my AMD64 with 2GB of memory, but a coworker tried on his x86 machine and it crashed immediately. This patch fixes the check in skb_header_pointer to handle large positive offsets similar to skb_copy_bits. Invalid data can still be accessed using negative offsets (also similar to skb_copy_bits), anyone using negative offsets needs to verify them himself.

| * | [SPARC64]: Do proper DMA IRQ syncing on TomatilloDavid S. Miller2005-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was the main impetus behind adding the PCI IRQ shim. In order to properly order DMA writes wrt. interrupts, you have to write to a PCI controller register, then poll for that bit clearing. There is one bit for each interrupt source, and setting this register bit tells Tomatillo to drain all pending DMA from that device. Furthermore, Tomatillo's with revision less than 4 require us to do a block store due to some memory transaction ordering issues it has on JBUS. Signed-off-by: David S. Miller <davem@davemloft.net>
| * | [SPARC64]: Add support for IRQ pre-handlers.David S. Miller2005-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows a PCI controller to shim into IRQ delivery so that DMA queues can be drained, if necessary. If some bus specific code needs to run before an IRQ handler is invoked, the bus driver simply needs to setup the function pointer in bucket->irq_info->pre_handler and the two args bucket->irq_info->pre_handler_arg[12]. The Schizo PCI driver is converted over to use a pre-handler for the DMA write-sync processing it needs when a device is behind a PCI->PCI bus deeper than the top-level APB bridges. While we're here, clean up all of the action allocation and handling. Now, we allocate the irqaction as part of the bucket->irq_info area. There is an array of 4 irqaction (for PCI irq sharing) and a bitmask saying which entries are active. The bucket->irq_info is allocated at build_irq() time, not at request_irq() time. This simplifies request_irq() and free_irq() tremendously. The SMP dynamic IRQ retargetting code got removed in this change too. It was disabled for a few months now, and we can resurrect it in the future if we want. Signed-off-by: David S. Miller <davem@davemloft.net>

This patch also adds the PPDEV option in the sparc64 menu, near Parallel printer support in the 'General machine setup' submenu. All those ioctls seem to be compatible, since (correct me if I'm wrong) they dont use the 'long' type. See include/linux/ppdev.h. The application I used to test the new ioctls only used the following: PPEXCL PPCLAIM PPNEGOT PPGETMODES PPRCONTROL PPWCONTROL PPDATADIR PPWDATA PPRDATA But I beleive that the other ioctls will work fine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dynamic pci id logic has been bothering me for a while, and now that I started to look into how to move some of this to the driver core, I thought it was time to clean it all up. It ends up making the code smaller, and easier to follow, and fixes a few bugs at the same time (dynamic ids were not being matched everywhere, and so could be missed on some call paths for new devices, semaphore not needed to be grabbed when adding a new id and calling the driver core, etc.) I also renamed the function pci_match_device() to pci_match_id() as that's what it really does.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iSeries code keeps a pointer to the ItLpQueue in its paca struct. But all these pointers end up pointing to the one place, ie. xItLpQueue. So remove the pointer from the paca struct and just refer to xItLpQueue directly where needed. The only complication is that the spread_lpevents logic was implemented by having a NULL lpqueue pointer in the paca on CPUs that weren't supposed to process events. Instead we just compare the spread_lpevents value to the processor id to get the same behaviour.
