2005-07-05[TCP]: Move send test logic out of net/tcp.hDavid S. Miller
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>
2005-07-05[TCP]: Fix quick-ack decrementing with TSO.David S. Miller
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.

2005-07-05[TCP]: Simplify SKB data portion allocation with NETIF_F_SG.David S. Miller
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>

Dave, you were right and the sleeping locks in shaper were broken. Markus Kanet noticed this and also tested the patch below that switches locking to spinlocks. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-07-05[IPV4]: More broken memory allocation fixes for fib_trieRobert Olsson
Below a patch to preallocate memory when doing resize of trie (inflate halve) If preallocations fails it just skips the resize of this tnode for this time. The oops we got when killing bgpd (with full routing) is now gone. Patrick memory patch is also used. Signed-off-by: Robert Olsson <robert.olsson@its.uu.se> Signed-off-by: David S.

2005-07-05[IPV4]: Bug fix in rt_check_expire()Eric Dumazet
- rt_check_expire() fixes (an overflow occured if size of the hash was >= 65536) reminder of the bugfix: The rt_check_expire() has a serious problem on machines with large route caches, and a standard HZ value of 1000. With default values, ie ip_rt_gc_interval = 60*HZ = 60000 ; the loop count : for (t = ip_rt_gc_interval << rt_hash_log; t >= 0; overflows (t is a 31 bit value) as soon rt_hash_log is >= 16 (65536 slots in route cache hash table). In this case, rt_check_expire() does nothing at all Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-07-05[NET]: Hashed spinlocks in net/ipv4/route.cEric Dumazet
- Locking abstraction - Spinlocks moved out of rt hash table : Less memory (50%) used by rt hash table. it's a win even on UP. - Sizing of spinlocks table depends on NR_CPUS Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-07-05[PKT_SCHED]: Report rate estimator configuration errors during qdisc allocationThomas Graf
Current behaviour is to not report an error if a rate estimator is created together with a qdisc and the configuration of the rate estimator is bogus. This leads to unexpected behaviour because the user is not notified. New behaviour is to report the error and let the whole qdisc creation operation fail so the user is able to fix his mistake.

2005-07-05[NET]: Fix signedness issues in net/core/filter.cPatrick McHardy
This is the code to load packet data into a register: k = fentry->k; if (k < 0) { ... } else { u32 _tmp, *p; p = skb_header_pointer(skb, k, 4, &_tmp); if (p != NULL) { A = ntohl(*p); continue; } } skb_header_pointer checks if the requested data is within the linear area: int hlen = skb_headlen(skb); if (offset + len <= hlen) return skb->data + offset; When offset is within [INT_MAX-len+1..INT_MAX] the addition will result in a negative number which is <= hlen. 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. Thanks to Thomas Vögtle <thomas.voegtle@coreworks.de> for verifying the problem by crashing his machine and providing me with an Oops.

2005-07-03[PATCH] ARM: 2784/1: Fix the block cache flush operation rangeCatalin Marinas
Patch from Catalin Marinas The range for the ARMv6 block cache operations is inclusive but the kernel doesn't re-calculate the end address, causing a page fault when used (this only happens with support for cache aliasing, otherwise the blk_flush_kern_dcache_page() is not called).

From: Rob Punkunus <rpunkunus@nvidia.com> Rob Punkunus recently submitted a patch to enable support for MCP51/MCP55 in the amd74xx driver. This patch was whitespace-corrupted and didn't apply to 2.6.12 since MCP51 support was merged in the 2.6.12-rc series.
