2012-08-02exofs: readpage_strip: Add a BUG_ON to check for PageLocked(page)Kautuk Consul1-0/+2
readpage_strip can be called from several code paths all of which require that the page be locked before any operations are carried out. Since we export the exofs_readpage callback to the VFS, add a BUG_ON to check for PageLocked(page) to make sure that this understanding is never compromised.

2012-07-20pnfs-obj: Fix __r4w_get_page when offset is beyond i_sizeBoaz Harrosh1-3/+13
It is very common for the end of the file to be unaligned on stripe size. But since we know it's beyond file's end then the XOR should be preformed with all zeros. Old code used to just read zeros out of the OSD devices, which is a great waist. But what scares me more about this situation is that, we now have pages attached to the file's mapping that are beyond i_size. I don't like the kind of bugs this calls for. Fix both birds, by returning a global zero_page, if offset is beyond i_size. TODO: Change the API to ->__r4w_get_page() so a NULL can be returned without being considered as error, since XOR API treats NULL entries as zero_pages. [Bug since 3.2.

2012-07-20ore: Unlock r4w pages in exact reverse order of lockingBoaz Harrosh1-12/+12
The read-4-write pages are locked in address ascending order. But where unlocked in a way easiest for coding. Fix that, locks should be released in opposite order of locking, .i.e descending address order. I have not hit this dead-lock. It was found by inspecting the dbug print-outs. I suspect there is an higher lock at caller that protects us, but fix it regardless. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2012-07-20ore: Remove support of partial IO request (NFS crash)Boaz Harrosh1-7/+1
Do to OOM situations the ore might fail to allocate all resources needed for IO of the full request. If some progress was possible it would proceed with a partial/short request, for the sake of forward progress. Since this crashes NFS-core and exofs is just fine without it just remove this contraption, and fail.

2012-07-20ore: Fix NFS crash by supporting any unaligned RAID IOBoaz Harrosh1-31/+36
In RAID_5/6 We used to not permit an IO that it's end byte is not stripe_size aligned and spans more than one stripe. .i.e the caller must check if after submission the actual transferred bytes is shorter, and would need to resubmit a new IO with the remainder. Exofs supports this, and NFS was supposed to support this as well with it's short write mechanism. But late testing has exposed a CRASH when this is used with none-RPC layout-drivers. The change at NFS is deep and risky, in it's place the fix at ORE to lift the limitation is actually clean and simple. So here it is below. The principal here is that in the case of unaligned IO on both ends, beginning and end, we will send two read requests one like old code, before the calculation of the first stripe, and also a new site, before the calculation of the last stripe. If any "boundary" is aligned or the complete IO is within a single stripe. we do a single read like before. The code is clean and simple by splitting the old _read_4_write into 3 even parts: 1._read_4_write_first_stripe 2. _read_4_write_last_stripe 3. _read_4_write_execute And calling 1+3 at the same place as before. 2+3 before last stripe, and in the case of all in a single stripe then 1+2+3 is preformed additively. Why did I not think of it before. Well I had a strike of genius because I have stared at this code for 2 years, and did not find this simple solution, til today. Not that I did not try. This solution is much better for NFS than the previous supposedly solution because the short write was dealt with out-of-band after IO_done, which would cause for a seeky IO pattern where as in here we execute in order. At both solutions we do 2 separate reads, only here we do it within a single IO request. (And actually combine two writes into a single submission) NFS/exofs code need not change since the ORE API communicates the new shorter length on return, what will happen is that this case would not occur anymore. hurray!!

2012-06-30acpi_pad: fix power_saving thread deadlockStuart Hayes1-3/+4
The acpi_pad driver can get stuck in destroy_power_saving_task() waiting for kthread_stop() to stop a power_saving thread. The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu(). This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981 Cc: stable@vger.kernel.org Signed-off-by: Stuart Hayes <Stuart_Hayes@Dell.com> Signed-off-by: Len Brown <len.brown@intel.com>

2012-06-29printk: flush continuation lines immediately to consoleKay Sievers1-68/+176
Continuation lines are buffered internally, intended to merge the chunked printk()s into a single record, and to isolate potentially racy continuation users from usual terminated line users. This though, has the effect that partial lines are not printed to the console in the moment they are emitted. In case the kernel crashes in the meantime, the potentially interesting printed information would never reach the consoles. Here we share the continuation buffer with the console copy logic, and partial lines are always immediately flushed to the available consoles. They are still buffered internally to improve the readability and integrity of the messages and minimize the amount of needed record headers to store.

The bug was introduced back in the lazy interrupt handling rework of 3.4 but was hidden until recently because hard_irq_disable did nothing. This issue will eventually appear in 3.4 stable since the hard_irq_disable fix is marked stable, so mark this one for stable too.

2012-06-29powerpc/ftrace: Do not trace restore_interrupts()Steven Rostedt1-1/+1
As I was adding code that affects all archs, I started testing function tracer against PPC64 and found that it currently locks up with 3.4 kernel. I figured it was due to tracing a function that shouldn't be, so I went through the following process to bisect to find the culprit: cat /debug/tracing/available_filter_functions > t num=`wc -l t` sed -ne "1,${num}p" t > t1 let num=num+1 sed -ne "${num},$p" t > t2 cat t1 > /debug/tracing/set_ftrace_filter echo function /debug/tracing/current_tracer <failed? bisect t1, if not bisect t2> It finally came down to this function: restore_interrupts() I'm not sure why this locks up the system. It just seems to prevent scheduling from occurring. Interrupts seem to still work, as I can ping the box. But all user processes freeze. When restore_interrupts() is not traced, function tracing works fine.

In entry_64.S version of ret_from_except_lite, you'll notice that in the !preempt case, after we've checked MSR_PR we test for any TIF flag in _TIF_USER_WORK_MASK to decide whether to go to do_work or not. However, in the preempt case, we do a convoluted trick to test SIGPENDING only if PR was set and always test NEED_RESCHED ... but we forget to test any other bit of _TIF_USER_WORK_MASK !!! So that means that with preempt, we completely fail to test for things like single step, syscall tracing, etc... This should be fixed as the following path: - Test PR. If not set, go to resume_kernel, else continue. - If go resume_kernel, to do that original do_work. - If else, then always test for _TIF_USER_WORK_MASK to decide to do that original user_work, else restore directly.

Pull networking update from David Miller: 1) Pairing and deadlock fixes in bluetooth from Johan Hedberg. 2) Add device IDs for AR3011 and AR3012 bluetooth chips. From Giancarlo Formicuccia and Marek Vasut. 3) Fix wireless regulatory deadlock, from Eliad Peller. 4) Fix full TX ring panic in bnx2x driver, from Eric Dumazet. 5) Revert the two commits that added skb_orphan_try(), it causes erratic bonding behavior with UDP clients and the gains it used to give are mostly no longer happening due to how BQL works. From Eric Dumazet. 6) It took two tries, but Thomas Graf fixed a problem wherein we registered ipv6 routing procfs files before their backend data were initialized properly. 7) Fix max GSO size setting in be2net, from Sarveshwar Bandi. 8) PHY device id mask is wrong for KSZ9021 and KS8001 chips, fix from Jason Wang. 9) Fix use of stale SKB data pointer after skb_linearize() call in batman-adv, from Antonio Quartulli. 10) Fix memory leak in IXGBE due to missing __GFP_COMP, from Alexander Duyck. 11) Fix probing of Gobi devices in qmi_wwan usbnet driver, from Bjørn Mork. 12) Fix suspend/resume and open failure handling in usbnet from Ming Lei. 13) Attempt to fix device r8169 hangs for certain chips, from Francois Romieu. 14) Fix advancement of RX dirty pointer in some situations in sh_eth driver, from Yoshihiro Shimoda. 15) Attempt to fix restart of IPV6 routing table dumps when there is an intervening table update. From Eric Dumazet. 16) Respect security_inet_conn_request() return value in ipv6 TCP. From Neal Cardwell. 17) Add another iPAD device ID to ipheth driver, from Davide Gerhard. 18) Fix access to freed SKB in l2tp_eth_dev_xmit(), and fix l2tp lockdep splats, from Eric Dumazet. 19) Make sure all bridge devices, regardless of whether they were created via netlink or ioctls, have their rtnetlink ops hooked up. From Thomas Graf and Stephen Hemminger. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (81 commits) 9p: fix min_t() casting in p9pdu_vwritef() can: flexcan: use be32_to_cpup to handle the value of dt entry xen/netfront: teardown the device before unregistering it. bridge: Assign rtnl_link_ops to bridge devices created via ioctl (v2) vhost: use USER_DS in vhost_worker thread ixgbe: Do not pad FCoE frames as this can cause issues with FCoE DDP net: l2tp_eth: use LLTX to avoid LOCKDEP splats mac802154: add missed braces net: l2tp_eth: fix l2tp_eth_dev_xmit race net/mlx4_en: Release QP range in free_resources net/mlx4: Use single completion vector after NOP failure net/mlx4_en: Set correct port parameters during device initialization ipheth: add support for iPad caif-hsi: Add missing return in error path caif-hsi: Bugfix - Piggyback'ed embedded CAIF frame lost caif: Clear shutdown mask to zero at reconnect. tcp: heed result of security_inet_conn_request() in tcp_v6_conn_request() ipv6: fib: fix fib dump restart batman-adv: fix race condition in TT full-table replacement batman-adv: only drop packets of known wifi clients ...

2012-06-279p: fix min_t() casting in p9pdu_vwritef()Dan Carpenter1-1/+1
I don't think we're actually likely to hit this limit but if we do then the comparison should be done as size_t. The original code is equivalent to: len = strlen(sptr) % USHRT_MAX; Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
