This patch adds missing pskb_may_pull calls to deal with non-linear packets that may arrive from pppoe or pppol2tp. It also copies cloned packets before writing over them. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-09-16[NET] skbuff: Add skb_cow_headHerbert Xu
This patch adds an optimised version of skb_cow that avoids the copy if the header can be modified even if the rest of the payload is cloned. This can be used in encapsulating paths where we only need to modify the header. As it is, this can be used in PPPOE and bridging.

2007-09-16[PPP] pppoe: Fill in header directly in __pppoe_xmitHerbert Xu
This patch removes the hdr variable (which is copied into the skb) and instead sets the header directly in the skb. It also uses __skb_push instead of skb_push since we've just checked using skb_cow for enough head room. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-09-16[PPP] pppoe: Fix data clobbering in __pppoe_xmit and return valueHerbert Xu
The function __pppoe_xmit modifies the skb data and therefore it needs to copy and skb data if it's cloned. In fact, it currently allocates a new skb so that it can return 0 in case of error without freeing the original skb. This is totally wrong because returning zero is meant to indicate congestion whereupon pppoe is supposed to wake up the upper layer once the congestion subsides. This makes sense for ppp_async and ppp_sync but is out-of-place for pppoe. This patch makes it always return 1 and free the skb.

2007-09-16[SCTP]: Convert bind_addr_list locking to RCUVlad Yasevich
Since the sctp_sockaddr_entry is now RCU enabled as part of the patch to synchronize sctp_localaddr_list, it makes sense to change all handling of these entries to RCU. This includes the sctp_bind_addrs structure and it's list of bound addresses. This list is currently protected by an external rw_lock and that looks like an overkill. There are only 2 writers to the list: bind()/bindx() calls, and BH processing of ASCONF-ACK chunks. These are already seriealized via the socket lock, so they will not step on each other. These are also relatively rare, so we should be good with RCU. The readers are varied and they are easily converted to RCU. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Acked-by: Paul E.

sctp_localaddr_list is modified dynamically via NETDEV_UP and NETDEV_DOWN events, but there is not synchronization between writer (even handler) and readers.

The commit 95c385 broke proper source address selection for cases in which there is a address which is makred 'deprecated'.

2007-09-16[SPARC64]: Fix lockdep, particularly on SMP.David S. Miller
As noted by Al Viro, when we try to call prom_set_trap_table() in the SMP trampoline code we try to take the PROM call spinlock which doesn't work because the current thread pointer isn't valid yet and lockdep depends upon that being correct. Furthermore, we cannot set the current thread pointer register because it can't be properly dereferenced until we return from prom_set_trap_table(). Kernel TLB misses only work after that call. So do the PROM call to set the trap table directly instead of going through the OBP library C code, and thus avoid the lock altogether. These calls are guarenteed to be serialized fully. Since there are now no calls to the prom_set_trap_table{_sun4v}() library functions, they can be deleted. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-09-16clockevents: prevent stale tick update on offline cpuThomas Gleixner
Taking a cpu offline removes the cpu from the online mask before the CPU_DEAD notification is done. The clock events layer does the cleanup of the dead CPU from the CPU_DEAD notifier chain. tick_do_timer_cpu is used to avoid xtime lock contention by assigning the task of jiffies xtime updates to one CPU. If a CPU is taken offline, then this assignment becomes stale. This went unnoticed because most of the time the offline CPU went dead before the online CPU reached __cpu_die(), where the CPU_DEAD state is checked. In the case that the offline CPU did not reach the DEAD state before we reach __cpu_die(), the code in there goes to sleep for 100ms. Due to the stale time update assignment, the system is stuck forever. Take the assignment away when a cpu is not longer in the cpu_online_mask. We do this in the last call to tick_nohz_stop_sched_tick() when the offline CPU is on the way to the final play_dead() idle entry. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2007-09-16clockevents: do not shutdown the oneshot broadcast deviceThomas Gleixner
When a cpu goes offline it is removed from the broadcast masks. If the mask becomes empty the code shuts down the broadcast device. This is wrong, because the broadcast device needs to be ready for the online cpu going idle (into a c-state, which stops the local apic timer). Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2007-09-16clockevents: Enforce oneshot broadcast when broadcast mask is set on resumeThomas Gleixner
The jinxed VAIO refuses to resume without hitting keys on the keyboard when this is not enforced. It is unclear why the cpu ends up in a lower C State without notifying the clock events layer, but enforcing the oneshot broadcast here is safe. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2007-09-16timekeeping: Prevent time going backwards on resumeThomas Gleixner
Timekeeping resume adjusts xtime by adding the slept time in seconds and resets the reference value of the clock source (clock->cycle_last). clock->cycle last is used to calculate the delta between the last xtime update and the readout of the clock source in __get_nsec_offset(). xtime plus the offset is the current time. The resume code ignores the delta which had already elapsed between the last xtime update and the actual time of suspend. If the suspend time is short, then we can see time going backwards on resume. Suspend: offs_s = clock->read() - clock->cycle_last; now = xtime + offs_s; timekeeping_suspend_time = read_rtc(); Resume: sleep_time = read_rtc() - timekeeping_suspend_time; xtime.tv_sec += sleep_time; clock->cycle_last = clock->read(); offs_r = clock->read() - clock->cycle_last; now = xtime + offs_r; if sleep_time_seconds == 0 and offs_r < offs_s, then time goes backwards. Fix this by storing the offset from the last xtime update and add it to xtime during resume, when we reset clock->cycle_last: sleep_time = read_rtc() - timekeeping_suspend_time; xtime.tv_sec += sleep_time; xtime += offs_s; /* Fixup xtime offset at suspend time */ clock->cycle_last = clock->read(); offs_r = clock->read() - clock->cycle_last; now = xtime + offs_r; Thanks to Marcelo for tracking this down on the OLPC and providing the necessary details to analyze the root cause.

2007-09-14[NET]: Fix two issues wrt. SO_BINDTODEVICE.David S. Miller
1) Comments suggest that setting optlen to zero will unbind the socket from whatever device it might be attached to. This hasn't been the case since at least 2.2.x because the first thing this function does is return -EINVAL if 'optlen' is less than sizeof(int). This check also means that passing in a two byte string doesn't work so well. It's almost as if this code was testing with "eth?" patterned strings and nothing else :-) Fix this by breaking the logic of this facility out into a seperate function which validates optlen more appropriately. The optlen==0 and small string cases now work properly. 2) We should reset the cached route of the socket after we have made the device binding changes, not before. Reported by Ben Greear.

2007-09-14[PATCH] bcm43xx: Fix cancellation of work queue crashesLarry Finger
A crash upon booting that is caused by bcm43xx has been reported [1] and found to be due to a work queue being reinitialized while work on that queue is still pending. This fix modifies the shutdown of work queues and prevents periodic work from being requeued during shutdown. With this patch, no more crashes on reboot were observed by the original reporter. I do not get that particular failure on my system; however, when running a large number of ifdown/ifup sequences, my system would kernel panic with the 'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT' errors. With this patch, no more of the first type of failure occur, and incidence of the second type is greatly reduced.

2007-09-14[MIPS] 20Kc: Disable use of WAIT instruction.Ralf Baechle
Another issue with 20Kc's WAIT, waiting for more details. With the 2.6.23 release immindent simply disable the use of WAIT instead of a more fancy workaround. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
