This replaces several uses of standard arithmetic with the DCCP sequence number arithmetic functions. The problem here is that the sequence number wrap-around was not taken into consideration. * Condition "seqp->ccid2s_seq <= prev->ccid2s_seq" has been replaced by dccp_delta_seqno(seqp->ccid2s_seq, prev->ccid2s_seq) >= 0 since if seqp is `before' prev, then the delta_seqno() is positive. * The test whether sequence numbers `a' and `b' are consecutive has the form dccp_delta_seqno(a, b) == 1 * Increment of ccid2hctx_rpseq could be done using dccp_inc_seqno(), but since here the incremented ccid2hctx_rpseq == seqno, used assignment instead.

skb's passed to ccid2_hc_tx_send_packet() are headerless, the packet type is decided later, in dccp_write_xmit(). Therefore the first test of the switch/case block is always true, the others are never reached. Signed-off-by:

This removes a test for `val < 1' which would only have been triggered when val < 0, due to a preceding test for 0. Fixed by using an unsigned type for cwnd (as in TCP) instead. Signed-off-by:

This removes an ugly BUG_ON which has been pointed out by Arnaldo. Instead of freezing up the machine, a `critical' message is now issued to the system log. There is potential of doing this more gracefully (eg. there are a few internal variables which could be updated despite the lack of memory), but that requires more complicated changes to the algorithm; thus a `FIXME' has been added.

This patch simplifies the interface of ccid2_hc_tx_alloc_seq(): * ccid2_hc_tx_alloc_seq() is always called with an argument of CCID2_SEQBUF_LEN; * other code - ccid2_hc_tx_check_sanity() - even depends on the assumption that ccid2_hc_tx_alloc_seq() has been called with this particular size; * passing the `gfp_t' argument to ccid2_hc_tx_alloc_seq() is redundant with gfp_any().

This enables applications to query the current value of the Maximum Packet Size via a socket option, suggested as a SHOULD in (RFC 4340, p. 102). This socket option is useful to avoid the annoying bail-out via `-EMSGSIZE'. In particular, as fragmentation is not currently supported (and its use is partly discouraged in RFC 4340). With this option, it is possible to size buffers accordingly, e.g. int buflen = dccp_get_cur_mps(sockfd); /* or */ if (msgsize > dccp_get_cur_mps(sockfd)) die("message is too large for this path"); Signed-off-by: -

This performs a minor optimisation: when ccid_hc_tx_send_packet returns a value greater zero, then the same call previously was done again at the begin of the while loop in dccp_wait_for_ccid. This patch exploits the available information and schedule-timeouts directly instead. Documentation also added. Signed-off-by:

I've tried to compile 2.6.23-rc8-mm2, but it fails on ipg.c with the error : ERROR: "__udivdi3" [drivers/net/ipg.ko] undefined! I've instigated a bit, and I've found this code in ipg.c : static void ipg_nic_txfree(struct net_device *dev) { struct ipg_nic_private *sp = netdev_priv(dev); void __iomem *ioaddr = sp->ioaddr; const unsigned int curr = ipg_r32(TFD_LIST_PTR_0) - (sp->txd_map / sizeof(struct ipg_tx)) - 1; unsigned int released, pending; sp->txd_map is an u64 because : dma_addr_t txd_map; And in asm-i386/types.h, I see : #ifdef CONFIG_HIGHMEM64G typedef u64 dma_addr_t; #else typedef u32 dma_addr_t; #endif I my config, I use CONFIG_HIGHMEM64G sizeof(struct ipg_tx) is an u32 So the div failed on i386 because of u64 / u32.

pasemi_mac: use buffer index pointer in clean_rx() Use the new features in B0 for buffer ring index on the receive side. This means we no longer have to search in the ring for where the buffer came from. Also cleanup the RX cleaning side a little, while I was at it. Note: Pre-B0 hardware is no longer supported, and needs a pile of other workarounds that are not being submitted for mainline inclusion. So the fact that this breaks old hardware is not a problem at this time. Signed-off-by:

pasemi_mac: further performance tweaks Misc driver tweaks for pasemi_mac: * Increase ring size (really needed mostly on 10G) * Take out an unneeded barrier * Move around a few prefetches and reorder a few calls * Don't try to clean on full tx buffer, just let things take their course and stop the queue directly * Avoid filling on the same line as the interface is working on to reduce cache line bouncing * Avoid unneeded clearing of software state (and make the interface shutdown code handle it) * Fix up some of the tx ring wrap logic.

pasemi_mac: add local skb alignment Add local SKB alignment to pasemi_mac, since ppc64 in general has it at 0 because of design flaws in some of the IBM server bridge chips. However, for PWRficient doing the unaligned copies is more expensive than doing unaligned DMA so make sure the data is aligned instead. Signed-off-by:

pasemi_mac: workaround for erratum 5971 Implement workarounds for erratum 5971, where L2 hints aren't considered properly unless the way hint is enabled on the interface. Since L2 isn't setup to dedicate a way to headers, we need to reset the packet count by hand so it won't run out of credits. Signed-off-by:

pasemi_mac: fix bug in receive buffer dma mapping skb->len isn't actually set to the size of the allocated skb, so don't try to use it when figuring out how much to map. (This hasn't surfaced as a real bug because we effectively disable translation for the interface, but it still needs fixing for the future) Signed-off-by:

This patch adds sta_notify callback and removes sta_table_notification which was not used by any driver. sta_notify() is essential for drivers that keeps notion of station internally and need to be notified about removal or addition of a station to the (I)BSS or assocation to an AP. This version adds interface id to the parameter list as suggested by Johannes Berg Signed-off-by:

This improves radiotap injection by removing the shortcut over TX handlers that led to BUGS when injecting frames without setting a rate and also resulted in various other quirks. Now, TX handlers are run but some information that was present in the radiotap header is used instead of automatic settings. Signed-off-by:

Johannes Berg authored
This moves the sta_process RX handler to after decryption so that frames that cannot be decrypted don't influence statistics, it is likely that they were injected or something else is totally wrong. Signed-off-by:
