Remove the lock_cpu_hotplug()/unlock_cpu_hotplug() calls from net_dma_rebalance The lock_cpu_hotplug()/unlock_cpu_hotplug() sequence in net_dma_rebalance is both incorrect (as pointed out by David Miller) because lock_cpu_hotplug() may sleep while the net_dma_event_lock spinlock is held, and unnecessary (as pointed out by Andrew Morton) as spin_lock() disables preemption which protects from CPU hotplug events.

This patch fixes a bug in the DECnet routing code where we were selecting a loopback device in preference to an outward facing device even when the destination was known non-local. This patch should fix the problem. Signed-off-by:

From: Catherine Zhang <cxzhang@watson.ibm.com> This patch implements a cleaner fix for the memory leak problem of the original unix datagram getpeersec patch. Instead of creating a security context each time a unix datagram is sent, we only create the security context when the receiver requests it. This new design requires modification of the current unix_getsecpeer_dgram LSM hook and addition of two new hooks, namely, secid_to_secctx and release_secctx. The former retrieves the security context and the latter releases it. A hook is required for releasing the security context because it is up to the security module to decide how that's done. In the case of Selinux, it's a simple kfree operation. Acked-by:

The skb_queue_head_init() function is used both in drivers for private use and in the core networking code. The usage models are vastly set of functions that is only softirq safe; while the driver usage tends to be more limited to a few hardirq safe accessor functions. Rather than annotating all 133+ driver usages, for now just split this lock into a per queue class. This change is obviously safe and probably should make 2.6.18. Signed-off-by:

When I tested linux kernel 2.6.71.7 about statistics "ipv6IfStatsOutFragCreates", and found that it couldn't increase correctly. The criteria is RFC 2465: ipv6IfStatsOutFragCreates OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of output datagram fragments that have been generated as a result of fragmentation at this output interface." ::= { ipv6IfStatsEntry 15 } I think there are two issues in Linux kernel. 1st: RFC2465 specifies the counter is "The number of output datagram fragments...". I think increasing this counter after output a fragment successfully is better. And it should not be increased even though a fragment is created but failed to output. 2nd: If we send a big ICMP/ICMPv6 echo request to a host, and receive ICMP/ICMPv6 echo reply consisted of some fragments. As we know that in Linux kernel first fragmentation occurs in ICMP layer(maybe saying transport layer is better), but this is not the "real" fragmentation,just do some "pre-fragment" -- allocate space for date, and form a frag_list, etc. The "real" fragmentation happens in IP layer -- set offset and MF flag and so on. So I think in "fast path" for ip_fragment/ip6_fragment, if we send a fragment which "pre-fragment" by upper layer we should also increase "ipv6IfStatsOutFragCreates".

When I tested Linux kernel 2.6.17.7 about statistics "ipv6IfStatsInHdrErrors", found that this counter couldn't increase correctly. The criteria is RFC2465: ipv6IfStatsInHdrErrors OBJECT-TYPE SYNTAX Counter3 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of input datagrams discarded due to errors in their IPv6 headers, including version number mismatch, other format errors, hop count exceeded, errors discovered in processing their IPv6 options, etc." ::= { ipv6IfStatsEntry 2 } When I send TTL=0 and TTL=1 a packet to a router which need to be forwarded, router just sends an ICMPv6 message to tell the sender that TIME_EXCEED and HOPLIMITS, but no increments for this counter(in the function ip6_forward).

We have a more complete solution in the works, involving the seperation of CHECKSUM_HW on input vs. output, and having netfilter properly do incremental checksums. But that is a very involved patch and is thus 2.6.19 material. What we have now is infinitely better than the past, wherein all TSO packets were dropped due to corrupt checksums as soon at the NAT module was loaded. At least now, the checksums do get fixed up, it just isn't the cleanest nor most optimal solution. Signed-off-by: -

Add a dev_alloc_skb variant that takes a struct net_device * paramater. For now that paramater is unused, but I'll use it to allocate the skb from node-local memory in a follow-up patch. Also there have been some other plans mentioned on the list that can use it. Signed-off-by:

Based upon guidance from Alexey Kuznetsov. When linger2 is active, we check to see if the fin_wait2 timeout is longer than the timewait. If it is, we schedule the keepalive timer for the difference between the timewait timeout and the fin_wait2 timeout. When this orphan socket is seen by tcp_keepalive_timer() it will try to transform this fin_wait2 socket into a fin_wait2 mini-socket, again if linger2 is active. Not all paths were setting this initial keepalive timer correctly. The tcp input path was doing it correctly, but tcp_close() wasn't, potentially making the socket linger longer than it really needs to. Signed-off-by: -

The patch below fixes a problem in the iptables SECMARK target, where the user-supplied 'selctx' string may not be nul-terminated. From initial analysis, it seems that the strlen() called from selinux_string_to_sid() could run until it arbitrarily finds a zero, and possibly cause a kernel oops before then. The impact of this appears limited because the operation requires CAP_NET_ADMIN, which is essentially always root. Also, the module is not yet in wide use. Signed-off-by:

Refer to RFC2012, tcpAttemptFails is defined as following: tcpAttemptFails OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of times TCP connections have made a direct transition to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state." ::= { tcp 7 } When I lookup into RFC793, I found that the state change should occured under following condition: 1. SYN-SENT -> CLOSED a) Received ACK,RST segment when SYN-SENT state. 2. SYN-RCVD -> CLOSED b) Received SYN segment when SYN-RCVD state(came from LISTEN). c) Received RST segment when SYN-RCVD state(came from SYN-SENT). d) Received SYN segment when SYN-RCVD state(came from SYN-SENT). 3. SYN-RCVD -> LISTEN e) Received RST segment when SYN-RCVD state(came from LISTEN). In my test, those direct state transition can not be counted to tcpAttemptFails.

The current users of ip6_dst_lookup can be divided into two classes: 1) The caller holds no locks and is in user-context (UDP). 2) The caller does not want to lookup the dst cache at all. The second class covers everyone except UDP because most people do the cache lookup directly before calling ip6_dst_lookup. This patch adds ip6_sk_dst_lookup for the first class. Similarly ip6_dst_store users can be divded into those that need to take the socket dst lock and those that don't. This patch adds __ip6_dst_store for those (everyone except UDP/datagram) that don't need an extra lock. Signed-off-by:

Since we now use the generic backlight infrastructure, I think we need to call rivafb_bl_init before calling register_framebuffer since otherwise rivafb_bl_init might race with the framebuffer layer already opening the device and setting up the video mode. In this case we might end up with a not yet fully intialized backlight (info->bl_dev still NULL) when calling riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel dies without any further notice during boot. This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb would be affected too - I can fix that too but don't have any hardware to test this on. Cc: "Antonino A.

This patch fixes several problems: - The legacy backlight value might be set at interrupt time. Introduced a worker to prevent it from directly calling the backlight code. - via-pmu allows the backlight to be grabbed, in which case we need to prevent other kernel code from changing the brightness. - Don't send PMU requests in via-pmu-backlight when the machine is about to sleep or waking up. - More Kconfig fixes.

Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw too much power when suspended to RAM, reducing drastically the battery lifetime. The solution is to enable suspend-to-D2 on these machines. They are whitelisted through their subsystem vendor/device ID. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=3022 The patch introduces a framework to alter the pm_mode and reinit_func fields of the radeonfb_info structure based on a whitelist. This should facilitate future hardware-dependent workarounds. The workaround for the Samsung P35 that is already in the radeonfb code has been rewritten using this framework. The behavior can be overridden with module options: i) video=radeonfb:force_sleep=1 enable suspend-to-D2 also on non-whitelisted machines (useful for testing new notebook models), ii) video=radeonfb:ignore_devlist=1 Disable checking the whitelist and do not apply any workarounds.

The backlight and lcd subsystems can be notified by the framebuffer layer of blanking events. However, these subsystems, as a whole, can function independently from the framebuffer layer. But in order to enable to the lcd and backlight subsystems, the framebuffer has to be compiled also, effectively sucking in a huge amount of unneeded code. To prevent dependency problems, separate out the framebuffer notification mechanism from the framebuffer layer and permanently link it to the kernel. Signed-off-by:

Based on a bug report from Russ Ross <russruss@gmail.com> According to the spec: "The remove request asks the file server both to remove the file represented by fid and to clunk the fid, even if the remove fails." but the Linux client seems to expect the fid to be valid after a failed remove attempt. Specifically, I'm getting this behavior when attempting to remove a non-empty directory. Signed-off-by:
