Detect user space by the unwind frame with predicate PRED_USER_STACK set, instead of a user space IP. Tighten up the last ditch check for running off the top of the kernel stack. Based on a suggestion by David Mosberger, reworked to fit the current tree. This survives my stress test which used to break 2.6.9 kernels. Unlike 2.6.11, the stress test now unwinds to the correct point, so gdb can get the user space registers. Signed-off-by:

Change the value of the SAL call number for a new SAL request. The initial implementation in the PROM did not match what the OS expected. Since the OS can run on PROMs that do not implement the new call, changing the call number avoids the issue. New PROMs will implement the new call number. (This avoids problems with the 4.05 PROM).

The sparc32 ksyms is missing a few more symbols, these are primarily related to SMP, and will be needed as SMP gets beaten back into functionality. Specifically, add __cpu_data (PER_CPU), cpu_online_map, and phys_cpu_present_map. This patch assumes that the earlier "linux-2.6.11-sparc-fixksyms.patch" is applied, otherwise, it will apply with fuzz. Signed-off-by:

Using the same logic as the other framebuffer fixes committed in 2.6.11, this is a set of fixes to make TCX functional on the console again. Adds the tcx_pan_display function, sets the all->info.var.{red,green,blue}.length values to 8, and runs fb_set_cmap. Also looks for the correct SUNW,tcx prom value. This patch just slipped through the cracks. Originally by: Georg Chini <georg.chini@triaton-webhosting.com> Signed-off-by: -

Calculate hashtable size to fit into a page instead of a hardcoded 256 buckets hash table. Results in a 1024 buckets hashtable on most systems. Replace old naive extract-8-lsb-bits algorithm with a better algorithm xor'ing 3 or 4 bit fields at the size of the hashtable array index in order to improve distribution if the majority of the lower bits are unused while keeping zero collision behaviour for the most common use case. Thanks to Wang Jian <lark@linux.net.cn> for bringing this issue to attention and to Eran Mann <emann@mrv.com> for the initial idea for this new algorithm. Signed-off-by:

The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect length final argument. However, the length argument turns out to be superfluous. I was just reading ipv6_skip_exthdr and it occured to me that we can get rid of len altogether. The only place where len is used is to check whether the skb has two bytes for ipv6_opt_hdr. This check is done by skb_header_pointer/skb_copy_bits anyway. Now it might appear that we've made the code slower by deferring the check to skb_copy_bits. However, this check should not trigger in the common case so this is OK. Signed-off-by:

The problem is that when doing MTU discovery, the too-large segments in the write queue will be calculated as having a pcount of >1. When tcp_write_xmit() is trying to send, tcp_snd_test() fails the cwnd test when pcount > cwnd. The segments are eventually transmitted one at a time by keepalive, but this can take a long time. This patch checks if TSO is enabled when setting pcount. Signed-off-by:

The NAT changes in 2.6.11 changed the position where helpers are called and perform packet mangling. Before 2.6.11, a NAT helper was called before the packet was NATed and had its sequence number adjusted. Since 2.6.11, the helpers get packets with already adjusted sequence numbers. This breaks sequence number adjustment, adjust_tcp_sequence() needs the original sequence number to determine whether a packet was a retransmission and to store it for further corrections. It can't be reconstructed without more information than available, so this patch restores the old order by calling helpers from a new conntrack hook two priorities below ip_conntrack_confirm() and adjusting the sequence number from a new NAT hook one priority below ip_conntrack_confirm().
