3d90268 Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux Pull drm fix from Dave Airlie: "Just a quick fix that a few people have reported, be nice to have in asap" The drm tree seems to be very confused about 64-bit divides. Here it uses a slow 64-by-64 bit divide to divide by a small constant. Oh well. Doesn't look performance-critical, just stupid. * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: drm/radeon: fix 64 bit divide in SI spm code 04 August 2013, 18:44:18 UTC
387aae6 tmpfs: fix SEEK_DATA/SEEK_HOLE regression Commit 46a1c2c7ae53 ("vfs: export lseek_execute() to modules") broke the tmpfs SEEK_DATA/SEEK_HOLE implementation, because vfs_setpos() converts the carefully prepared -ENXIO to -EINVAL. Other filesystems avoid it in error cases: do the same in tmpfs.

The reason for this is that install_special_mapping() expects the page array to stick around, and as this was only inserting one page which was stored on the kernel stack, that's why this was blowing up.

6a8b7f0 netlabel: use domain based selectors when address based selectors are not available NetLabel has the ability to selectively assign network security labels to outbound traffic based on either the LSM's "domain" (different for each LSM), the network destination, or a combination of both. Depending on the type of traffic, local or forwarded, and the type of traffic selector, domain or address based, different hooks are used to label the traffic; the goal being minimal overhead. Unfortunately, there is a bug such that a system using NetLabel domain based traffic selectors does not correctly label outbound local traffic that is not assigned to a socket. The issue is that in these cases the associated NetLabel hook only looks at the address based selectors and not the domain based selectors. This patch corrects this by checking both the domain and address based selectors so that the correct labeling is applied, regardless of the configuration type. In order to acomplish this fix, this patch also simplifies some of the NetLabel domainhash structures to use a more common outbound traffic mapping type: struct netlbl_dommap_def. This simplifies some of the code in this patch and paves the way for further simplifications in the future. Signed-off-by: Paul Moore <pmoore@redhat.com> Signed-off-by: David S.

5f671d6 net: check net.core.somaxconn sysctl values It's possible to assign an invalid value to the net.core.somaxconn sysctl variable, because there is no checks at all. The sk_max_ack_backlog field of the sock structure is defined as unsigned short. Therefore, the backlog argument in inet_listen() shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall is truncated to the somaxconn value. So, the somaxconn value shouldn't exceed 65535 (USHRT_MAX). Also, negative values of somaxconn are meaningless. before: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 net.core.somaxconn = 65536 $ sysctl -w net.core.somaxconn=-100 net.core.somaxconn = -100 after: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 error: "Invalid argument" setting key "net.core.somaxconn" $ sysctl -w net.core.somaxconn=-100 error: "Invalid argument" setting key "net.core.somaxconn" Based on a prior patch from Changli Gao.

Fix from Colin Cross addresses this by adding a process flag to mark the hibernate/suspend process to inform the freezer that that process should be ignored. - One of the recent cpufreq reverts uncovered a problem in the core causing the cpufreq driver module refcount to become negative after a system suspend-resume cycle. Fix from Rafael J Wysocki. - The evaluation of the ACPI battery _BIX method has never worked correctly, because the commit that added support for it forgot to take the "Revision" field in the return package into account.

697aeba ALSA: hda - Fix missing fixup for Mac Mini with STAC9221 A fixup for Apple Mac Mini was lost during the adaption to the generic parser because the fallback for the generic ID 8384:7680 was dropped, and it resulted in the silence output (and maybe other problems). Unfortunately, just adding the missing subsystem ID wasn't enough, in this case. The subsystem ID of this machine is 0000:0100 (what Apple thought...?), and since snd_hda_pick_fixup() doesn't take the vendor id zero into account, the driver ignored this entry. Now it's fixed to regard the vendor id zero as a valid value.

8a226b2 ipv6: prevent race between address creation and removal There's a race in IPv6 automatic addess assignment. The address is created with zero lifetime when it's added to various address lists. Before it gets assigned the correct lifetime, there's a window where a new address may be configured. This causes the semi-initiated address to be deleted in addrconf_verify. This was discovered as a reference leak caused by concurrent run of __ipv6_ifa_notify for both RTM_NEWADDR and RTM_DELADDR with the same address. Fix this by setting the lifetime before the address is added to inet6_addr_lst. A few notes: 1. In addrconf_prefix_rcv, by setting update_lft to zero, the if (update_lft) { ... } condition is no longer executed for newly created addresses. This is okay, as the ifp fields are set in ipv6_add_addr now and ipv6_ifa_notify is called (and has been called) through addrconf_dad_start. 2. The removal of the whole block under ifp->lock in inet6_addr_add is okay, too, as tstamp is initialized to jiffies in ipv6_add_addr.

2ac3ac8 ipv6: prevent fib6_run_gc() contention On a high-traffic router with many processors and many IPv6 dst entries, soft lockup in fib6_run_gc() can occur when number of entries reaches gc_thresh. This happens because fib6_run_gc() uses fib6_gc_lock to allow only one thread to run the garbage collector but ip6_dst_gc() doesn't update net->ipv6.ip6_rt_last_gc until fib6_run_gc() returns. On a system with many entries, this can take some time so that in the meantime, other threads pass the tests in ip6_dst_gc() (ip6_rt_last_gc is still not updated) and wait for the lock. They then have to run the garbage collector one after another which blocks them for quite long. Resolve this by replacing special value ~0UL of expire parameter to fib6_run_gc() by explicit "force" parameter to choose between spin_lock_bh() and spin_trylock_bh() and call fib6_run_gc() with force=false if gc_thresh is reached but not max_size.

36dd1f3 PCI: mvebu: Disable prefetchable memory support in PCI-to-PCI bridge The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able to dynamically set up MBus address decoding windows for PCI I/O and memory regions depending on the PCI devices enumerated by Linux. However, this emulated PCI-to-PCI bridge logic makes the Linux PCI core believe that prefetchable memory regions are supported (because the registers are read/write), while in fact no adress decoding window is ever created for such regions. Since the Marvell MBus address decoding windows do not distinguish memory regions and prefetchable memory regions, this patch takes a simple approach: change the PCI-to-PCI bridge emulation to let the Linux PCI core know that we don't support prefetchable memory regions. To achieve this, we simply make the prefetchable memory base a read-only register that always returns 0. Reading/writing all the other prefetchable memory related registers has no effect. This problem was originally reported by Finn Hoffmann <finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem was that the PCI-to-PCI bridge emulation was making the Linux PCI core believe that we support prefetchable memory, so the Linux PCI core was only filling the prefetchable memory base and limit registers, which does not lead to a MBus window being created. The below patch has been confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has otherwise been successfully tested on the Armada XP GP platform with a e1000e PCIe NIC and a Marvell SATA PCIe card.

1f1059f Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== This pull request is intended for the 3.11 stream. It is a bit larger than usual, as it includes pulls from most of my feeder trees as well... For the Bluetooth bits, Gustavo says: "A few fixes and devices ID additions for 3.11: * There are 4 new ath3k device ids * Fixed stack memory usage in ath3k. * Fixed the init process of BlueFRITZ! devices, they were failing to init due to an unsupported command we sent. * Fixed wrong use of PTR_ERR in btusb code that was preventing intel devices to work properly. * Fixed race condition between hci_register_dev() and hci_dev_open() that could cause a NULL pointer dereference. * Fixed race condition that could call hci_req_cmd_complete() and make some devices to fail as showed in the log added to the commit message." Regarding the NFC bits, Samuel says: "We have: 1) A build failure fix for the NCI SPI transport layer due to a missing CRC_CCITT Kconfig dependency. 2) A netlink command rename: CMD_FW_UPLOAD was merged during the 3.11 merge window but the typical terminology for loading a firmware to a target is firmware download rather than upload. In order to avoid any confusion in a file exported to userspace, we rename this command to CMD_FW_DOWNLOAD." Samuel's item #2 isn't strictly a fix, but it seems safe and should avoid confusion in the future. As for the mac80211 bits, Johannes says: "I only have three fixes this time, a fix for a suspend regression, a patch correcting the initiator in regulatory code and one fix for mesh station powersave." With respect to the iwlwifi bits, Johannes says: "We have a scan fix for passive channels, a new PCI device ID for an old device, a NIC reset fix, an RF-Kill fix, a fix for powersave when GO interfaces are present as well as an aggregation session fix (for a corner case) and a workaround for a firmware design issue - it only supports a single GTK in D3." Bringing-up the rear with the Atheros trees, Kalle says: "Geert Uytterhoeven fixed an ath10k build problem when NO_DMA=y. I added a missing MAINTAINERS entry for ath10k and updated ath6kl git tree location." Along with the above... Arend van Spriel fixes a brcmfmac WARNING when unplugging the device. Avinash Patil proves a couple of minor mwifiex fixes relating to P2P mode. Luciano Coelho updates the MAINTAINERS entry for the wilink drivers. Stanislaw Gruszka brings an rt2x00 fix for a queue start/stop problem. Stone Piao fixes another mwifiex problem, a command timeout related to P2P mode. Tomasz Moń corrects an endian problem in mwifiex. I'll remind my feeder maintainers to slowdown the patchflow.

447383d NFSD/sunrpc: avoid deadlock on TCP connection due to memory pressure. Since we enabled auto-tuning for sunrpc TCP connections we do not guarantee that there is enough write-space on each connection to queue a reply. If memory pressure causes the window to shrink too small, the request throttling in sunrpc/svc will not accept any requests so no more requests will be handled. Even when pressure decreases the window will not grow again until data is sent on the connection. This means we get a deadlock: no requests will be handled until there is more space, and no space will be allocated until a request is handled. This can be simulated by modifying svc_tcp_has_wspace to inflate the number of byte required and removing the 'svc_sock_setbufsize' calls in svc_setup_socket. I found that multiplying by 16 was enough to make the requirement exceed the default allocation. With this modification in place: mount -o vers=3,proto=tcp 127.0.0.1:/home /mnt would block and eventually time out because the nfs server could not accept any requests. This patch relaxes the request throttling to always allow at least one request through per connection. It does this by checking both sk_stream_min_wspace() and xprt->xpt_reserved are zero. The first is zero when the TCP transmit queue is empty. The second is zero when there are no RPC requests being processed. When both of these are zero the socket is idle and so one more request can safely be allowed through. Applying this patch allows the above mount command to succeed cleanly. Tracing shows that the allocated write buffer space quickly grows and after a few requests are handled, the extra tests are no longer needed to permit further requests to be processed. The main purpose of request throttling is to handle the case when one client is slow at collecting replies and the send queue gets full of replies that the client hasn't acknowledged (at the TCP level) yet. As we only change behaviour when the send queue is empty this main purpose is still preserved. Reported-by: Ben Myers <bpm@sgi.com> Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J.

fe956a1 powerpc/windfarm: Fix noisy slots-fan on Xserve (rm31) slots-fan on G5 Xserve is always running at full speed with windfarm_rm31 driver, resulting in a very high acoustic noise level. It seems the fan parameters are incorrect, and have been copied from the Drive Bay fan (RPM, not present on rm31) of the legacy therm_pm72 driver. This patch changes the parameters to match the Slots fan (PWM) of therm_pm72. With the patch, slots-fan speed drops from 99% to 19% during normal use, and slots-temp settle to ~42'C.

3be7db6 powerpc: VPHN topology change updates all siblings When an associativity level change is found for one thread, the siblings threads need to be updated as well. This is done today for PRRN in stage_topology_update() but is missing for VPHN in update_cpu_associativity_changes_mask(). This patch will correctly update all thread siblings during a topology change. Without this patch a topology update can result in a CPU in init_sched_groups_power() getting stuck indefinitely in a loop. This loop is built in build_sched_groups(). As a result of the thread moving to a node separate from its siblings the struct sched_group will have its next pointer set to point to itself rather than the sched_group struct of the next thread. This happens because we have a domain without the SD_OVERLAP flag, which is correct, and a topology that doesn't conform with reality (threads on the same core assigned to different numa nodes). When this list is traversed by init_sched_groups_power() it will reach the thread's sched_group structure and loop indefinitely; the cpu will be stuck at this point. The bug was exposed when VPHN was enabled in commit b7abef0 (v3.9).

At the time we named them "CNT" to match x86. However in commit 89ccf46 "Rename 'performance counter interrupt'", the x86 guys renamed theirs from "CNT" to "PMI". Arguably changing the name could break someone's script, but I think the chance of that is minimal, and it's preferable to have a name that 1) is somewhat meaningful, and 2) matches x86.

b00589a bridge: disable snooping if there is no querier If there is no querier on a link then we won't get periodic reports and therefore won't be able to learn about multicast listeners behind ports, potentially leading to lost multicast packets, especially for multicast listeners that joined before the creation of the bridge. These lost multicast packets can appear since c5c23260594 ("bridge: Add multicast_querier toggle and disable queries by default") in particular. With this patch we are flooding multicast packets if our querier is disabled and if we didn't detect any other querier. A grace period of the Maximum Response Delay of the querier is added to give multicast responses enough time to arrive and to be learned from before disabling the flooding behaviour again.

It will be even wrong on a machine with 2 CPUs (4 cores). But all needed information is contained in the PAT entries for the serial ports. mod[0] contains the iosapic address and mod_info has some indications for the interrupt input (at least it looks like it).

50861f5 parisc: Fix cache routines to ignore vma's with an invalid pfn The parisc architecture does not have a pte special bit. As a result, special mappings are handled with the VM_PFNMAP and VM_MIXEDMAP flags. VM_MIXEDMAP mappings may or may not have a "struct page" backing. When pfn_valid() is false, there is no "struct page" backing. Otherwise, they are treated as normal pages. The FireGL driver uses the VM_MIXEDMAP without a backing "struct page". This treatment caused a panic due to a TLB data miss in update_mmu_cache. This appeared to be in the code generated for page_address(). We were in fact using a very circular bit of code to determine the physical address of the PFN in various cache routines. This wasn't valid when there was no "struct page" backing. The needed address can in fact be determined simply from the PFN itself without using the "struct page". The attached patch updates update_mmu_cache(), flush_cache_mm(), flush_cache_range() and flush_cache_page() to check pfn_valid() and to directly compute the PFN physical and virtual addresses.

33cb876 vmpressure: make sure there are no events queued after memcg is offlined vmpressure is called synchronously from reclaim where the target_memcg is guaranteed to be alive but the eventfd is signaled from the work queue context. This means that memcg (along with vmpressure structure which is embedded into it) might go away while the work item is pending which would result in use-after-release bug. We have two possible ways how to fix this. Either vmpressure pins memcg before it schedules vmpr->work and unpin it in vmpressure_work_fn or explicitely flush the work item from the css_offline context (as suggested by Tejun). This patch implements the later one and it introduces vmpressure_cleanup which flushes the vmpressure work queue item item. It hooks into mem_cgroup_css_offline after the memcg itself is cleaned up.

9d8c5b5 mm: zbud: fix condition check on allocation size zbud_alloc() incorrectly verifies the size of allocation limit. It should deny the allocation request greater than (PAGE_SIZE - ZHDR_SIZE_ALIGNED - CHUNK_SIZE), not (PAGE_SIZE - ZHDR_SIZE_ALIGNED) which has no remaining spaces for its buddy. There is no point in spending the entire zbud page storing only a single page, since we don't have any benefits.

e180cf8 thp, mm: avoid PageUnevictable on active/inactive lru lists active/inactive lru lists can contain unevicable pages (i.e. ramfs pages that have been placed on the LRU lists when first allocated), but these pages must not have PageUnevictable set - otherwise shrink_[in]active_list goes crazy: kernel BUG at /home/space/kas/git/public/linux-next/mm/vmscan.c:1122! 1090 static unsigned long isolate_lru_pages(unsigned long nr_to_scan, 1091 struct lruvec *lruvec, struct list_head *dst, 1092 unsigned long *nr_scanned, struct scan_control *sc, 1093 isolate_mode_t mode, enum lru_list lru) 1094 { ... 1108 switch (__isolate_lru_page(page, mode)) { 1109 case 0: ... 1116 case -EBUSY: ... 1121 default: 1122 BUG(); 1123 } 1124 } ... 1130 } __isolate_lru_page() returns EINVAL for PageUnevictable(page). For lru_add_page_tail(), it means we should not set PageUnevictable() for tail pages unless we're sure that it will go to LRU_UNEVICTABLE. Let's just copy PG_active and PG_unevictable from head page in __split_huge_page_refcount(), it will simplify lru_add_page_tail(). This will fix one more bug in lru_add_page_tail(): if page_evictable(page_tail) is false and PageLRU(page) is true, page_tail will go to the same lru as page, but nobody cares to sync page_tail active/inactive state with page. So we can end up with inactive page on active lru. The patch will fix it as well since we copy PG_active from head page. Signed-off-by: Kirill A.

ef2a2cb mm/swap.c: clear PageActive before adding pages onto unevictable list As a result of commit 13f7f78981e4 ("mm: pagevec: defer deciding which LRU to add a page to until pagevec drain time"), pages on unevictable lists can have both of PageActive and PageUnevictable set. This is not only confusing, but also corrupts page migration and shrink_[in]active_list. This patch fixes the problem by adding ClearPageActive before adding pages into unevictable list. It also cleans up VM_BUG_ONs. Signed-off-by: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Cc: Mel Gorman <mgorman@suse.de> Cc: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Cc: "Kirill A.
