2011-12-09sch_red: fix red_changeEric Dumazet
[ Upstream commit 1ee5fa1e9970a16036e37c7b9d5ce81c778252fc ] Le mercredi 30 novembre 2011 à 14:36 -0800, Stephen Hemminger a écrit : > (Almost) nobody uses RED because they can't figure it out. > According to Wikipedia, VJ says that: > "there are not one, but two bugs in classic RED." RED is useful for high throughput routers, I doubt many linux machines act as such devices. I was considering adding Adaptative RED (Sally Floyd, Ramakrishna Gummadi, Scott Shender), August 2001 In this version, maxp is dynamic (from 1% to 50%), and user only have to setup min_th (target average queue size) (max_th and wq (burst in linux RED) are automatically setup) By the way it seems we have a small bug in red_change() if (skb_queue_empty(&sch->q)) red_end_of_idle_period(&q->parms); First, if queue is empty, we should call red_start_of_idle_period(&q->parms); Second, since we dont use anymore sch->q, but q->qdisc, the test is meaningless. Oh well... [PATCH] sch_red: fix red_change() Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty, we start an idle period, not end it.

2011-12-09sch_red: fix red_calc_qavg_from_idle_timeEric Dumazet
[ Upstream commit ea6a5d3b97b768561db6358f15e4c84ced0f4f7e ] Since commit a4a710c4a7490587 (pkt_sched: Change PSCHED_SHIFT from 10 to 6) it seems RED/GRED are broken. red_calc_qavg_from_idle_time() computes a delay in us units, but this delay is now 16 times bigger than real delay, so the final qavg result smaller than expected.

2011-12-09inet: add a redirect generation id in inetpeerEric Dumazet
[ Upstream commit de68dca1816660b0d3ac89fa59ffb410007a143f ] Now inetpeer is the place where we cache redirect information for ipv4 destinations, we must be able to invalidate informations when a route is added/removed on host. As inetpeer is not yet namespace aware, this patch adds a shared redirect_genid, and a per inetpeer redirect_genid. This might be changed later if inetpeer becomes ns aware. Cache information for one inerpeer is valid as long as its redirect_genid has the same value than global redirect_genid.

2011-12-09ipv4: fix redirect handlingEric Dumazet
[ Upstream commit 9cc20b268a5a14f5e57b8ad405a83513ab0d78dc ] commit f39925dbde77 (ipv4: Cache learned redirect information in inetpeer.) introduced a regression in ICMP redirect handling. It assumed ipv4_dst_check() would be called because all possible routes were attached to the inetpeer we modify in ip_rt_redirect(), but thats not true. commit 7cc9150ebe (route: fix ICMP redirect validation) tried to fix this but solution was not complete. (It fixed only one route) So we must lookup existing routes (including different TOS values) and call check_peer_redir() on them.

[ Upstream commit 069294e813ed5f27f82613b027609bcda5f1b914 ] The AH4/6 ahash output callbacks pass nexthdr to xfrm_output_resume instead of the error code. This appears to be a copy+paste error from the input case, where nexthdr is expected. This causes the driver to continuously add AH headers to the datagram until either an allocation fails and the packet is dropped or the ahash driver hits a synchronous fallback and the resulting monstrosity is transmitted.

2011-12-09oprofile: Fix crash when unloading module (hr timer mode)Robert Richter
commit 87121ca504fd1d963a66b3fb0c72054b0fd9a177 upstream. Oprofile may crash in a KVM guest while unlaoding modules. This happens if oprofile_arch_init() fails and oprofile switches to the hr timer mode as a fallback. In this case oprofile_arch_exit() is called, but it never was initialized properly which causes the crash. This patch fixes this. oprofile: using timer interrupt.

commit 6a8943d9ec2567572fca25cf69ad45844d0141a3 upstream. The current code checks if abs(delta_delta.tv_sec) is greater or equal to two before it discards the old delta value, but this can trigger at close to -1 seconds since -1.000000001 seconds is stored as tv_sec -2 and tv_nsec 999999999 in a normalized timespec. rtc_resume had an early return check if the rtc value had not changed since rtc_suspend. This effectivly stops time for the duration of the short sleep. Check if sleep_time is positive after all the adjustments have been applied instead since this allows the old_system adjustment in rtc_suspend to have an effect even for short sleep cycles.

commit 550acb19269d65f32e9ac4ddb26c2b2070e37f1c upstream. In irq_wait_for_interrupt(), the should_stop member is verified before setting the task's state to TASK_INTERRUPTIBLE and calling schedule(). In case kthread_stop sets should_stop and wakes up the process after should_stop is checked by the irq thread but before the task's state is changed, the irq thread might never exit: kthread_stop irq_wait_for_interrupt ------------ ---------------------- ... ... while (!kthread_should_stop()) { kthread->should_stop = 1; wake_up_process(k); wait_for_completion(&kthread->exited); ... set_current_state(TASK_INTERRUPTIBLE); ... schedule(); } Fix this by checking if the thread should stop after modifying the task's state.

2011-12-09cfg80211: amend regulatory NULL dereference fixLuis R. Rodriguez
commit 0bac71af6e66dc798bf07d0c0dd14ee5503362f9 upstream. Johannes' patch for "cfg80211: fix regulatory NULL dereference" broke user regulaotry hints and it did not address the fact that last_request was left populated even if the previous regulatory hint was stale due to the wiphy disappearing. Fix user reguluatory hints by only bailing out if for those regulatory hints where a request_wiphy is expected. The stale last_request considerations are addressed through the previous fixes on last_request where we reset the last_request to a static world regdom request upon reset_regdomains(). In this case though we further enhance the effect by simply restoring reguluatory settings completely. Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luis R.

2011-12-09cfg80211: fix race on init and driver registrationLuis R. Rodriguez
commit a042994dd377d86bff9446ee76151ceb6267c9ba upstream. There is a theoretical race that if hit will trigger a crash. The race is between when we issue the first regulatory hint, regulatory_hint_core(), gets processed by the workqueue and between when the first device gets registered to the wireless core. This is not easy to reproduce but it was easy to do so through the regulatory simulator I have been working on. This is a port of the fix I implemented there [1].

Upstream commit d305a6557b2c4dca0110f05ffe745b1ef94adb80. If addBA responses comes in just after addba_resp_timer has expired mac80211 will still accept it and try to open the aggregation session. This causes drivers to be confused and in some cases even crash. This patch fixes the race condition and makes sure that if addba_resp_timer has expired addBA response is not longer accepted and we do not try to open half-closed session.

Since we are running in batched mode (lazy) we don't actually set up the PTE mappings and the kmap_atomic is not done synchronously and ends up trying to dereference a page that has not been set. Looking at kmap_atomic_prot_pfn(), it uses 'arch_flush_lazy_mmu_mode' and doing the same in kmap_atomic_prot() and __kunmap_atomic() makes the problem go away. Interestingly, commit b8bcfe997e4615 ("x86/paravirt: remove lazy mode in interrupts") removed part of this to fix an interrupt issue - but it went to far and did not consider this scenario.

Unfortunately it introduced a regression: prior to that change we used to always set the mp_bus_not_pci bit, then clear it if we found a PCI bus. After it, we set mp_bus_not_pci for ISA buses, clear it for PCI buses, and leave it alone otherwise. In the cases of ISA and PCI, there's not much difference. But ISA is not the only non-PCI bus, so it's better to always set mp_bus_not_pci and clear it only for PCI. Without this change, Dan's Dell PowerEdge 4200 panics on boot with a log indicating interrupt routing trouble unless the "noapic" option is supplied. With this change, the machine boots reliably without "noapic".

2011-12-09sched, x86: Avoid unnecessary overflow in sched_clockSalman Qazi
commit 4cecf6d401a01d054afc1e5f605bcbfe553cb9b9 upstream. (Added the missing signed-off-by line) In hundreds of days, the __cycles_2_ns calculation in sched_clock has an overflow. cyc * per_cpu(cyc2ns, cpu) exceeds 64 bits, causing the final value to become zero. We can solve this without losing any precision. We can decompose TSC into quotient and remainder of division by the scale factor, and then use this to convert TSC into nanoseconds.

2011-12-09xHCI: fix bug in xhci_clear_command_ring()Andiry Xu
commit 158886cd2cf4599e04f9b7e10cb767f5f39b14f1 upstream. When system enters suspend, xHCI driver clears command ring by writing zero to all the TRBs. However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.

2011-12-09USB: EHCI: fix HUB TT scheduling issue with iso transferThomas Poussevin
commit 811c926c538f7e8d3c08b630dd5844efd7e000f6 upstream. The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. The IN iso stream can only start on the first uframe (0-2 for a 165 us) because of CSPLIT transactions. For the OUT iso stream there no such restriction. uframe 0-5 are possible. The idea of this patch is that the first uframe are precious (for IN TT iso stream) and we should allocate the last uframes first if possible. For that we reverse the order of uframe allocation (last uframe first). Here an example : hid interrupt stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 125 | 39 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- There no place for iso IN stream (uframe 0-2 are used) and we got "cannot submit datapipe for urb 0, error -28: not enough bandwidth" error. With the patch this become. iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- iso IN stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 125 | 40 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- Signed-off-by: Matthieu Castet <matthieu.castet@parrot.com> Signed-off-by: Thomas Poussevin <thomas.poussevin@parrot.com> Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
