2013-07-31vmpressure: make sure there are no events queued after memcg is offlinedMichal Hocko3-0/+18
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.

2013-07-31thp, mm: avoid PageUnevictable on active/inactive lru listsKirill A. Shutemov2-19/+5
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.

2013-07-31mm: mempolicy: fix mbind_range() && vma_adjust() interactionOleg Nesterov2-2/+6
vma_adjust() does vma_set_policy(vma, vma_policy(next)) and this is doubly wrong: 1. This leaks vma->vm_policy if it is not NULL and not equal to next->vm_policy. This can happen if vma_merge() expands "area", not prev (case 8). 2. This sets the wrong policy if vma_merge() joins prev and area, area is the vma the caller needs to update and it still has the old policy. Revert commit 1444f92c8498 ("mm: merging memory blocks resets mempolicy") which introduced these problems. Change mbind_range() to recheck mpol_equal() after vma_merge() to fix the problem that commit tried to address.

2013-07-31IPoIB: Fix pkey change flow for virtualization environmentsErez Shitrit1-13/+63
IPoIB's required behaviour w.r.t to the pkey used by the device is the following: - For "parent" interfaces (e.g ib0, ib1, etc) who are created automatically as a result of hot-plug events from the IB core, the driver needs to take whatever pkey vlaue it finds in index 0, and stick to that index. - For child interfaces (e.g ib0.8001, etc) created by admin directive, the driver needs to use and stick to the value provided during its creation. In SR-IOV environment its possible for the VF probe to take place before the cloud management software provisions the suitable pkey for the VF in the paravirtualed PKEY table index 0. When this is the case, the VF IB stack will find in index 0 an invalide pkey, which is all zeros. Moreover, the cloud managment can assign the pkey value at index 0 at any time of the guest life cycle. The correct behavior for IPoIB to address these requirements for parent interfaces is to use PKEY_CHANGE event as trigger to optionally re-init the device pkey value and re-create all the relevant resources accordingly, if the value of the pkey in index 0 has changed (from invalid to valid or from valid value X to invalid value Y). This patch enhances the heavy flushing code which is triggered by pkey change event, to behave correctly for parent devices. For child devices, the code remains the same, namely chases pkey value and not index.

2013-07-31IB/core: Create QP1 using the pkey index which contains the default pkeyJack Morgenstein1-1/+7
Currently, QP1 is created using pkey index 0. This patch simply looks for the index containing the default pkey, rather than hard-coding pkey index 0. This change will have no effect in native mode, since QP0 and QP1 are created before the SM configures the port, so pkey table will still be the default table defined by the IB Spec, in C10-123: "If non-volatile storage is not used to hold P_Key Table contents, then if a PM (Partition Manager) is not present, and prior to PM initialization of the P_Key Table, the P_Key Table must act as if it contains a single valid entry, at P_Key_ix = 0, containing the default partition key. All other entries in the P_Key Table must be invalid." Thus, in the native mode case, the driver will find the default pkey at index 0 (so it will be no different than the hard-coding). However, in SR-IOV mode, for VFs, the pkey table may be paravirtualized, so that the VF's pkey index zero may not necessarily be mapped to the real pkey index 0. For VFs, therefore, it is important to find the virtual index which maps to the real default pkey. This commit does the following for QP1 creation: 1. Find the pkey index containing the default pkey, and use that index if found. ib_find_pkey() returns the index of the limited-membership default pkey (0x7FFF) if the full-member default pkey is not in the table. 2. If neither form of the default pkey is found, use pkey index 0 (previous behavior).

2013-07-31IB/mlx4: Use default pkey when creating tunnel QPsJack Morgenstein1-2/+8
When creating tunnel QPs for special QP tunneling, look for the default pkey in the slave's virtual pkey table. If it is present, use the real pkey index where the default pkey is located. If the default pkey is not found in the pkey table, use the real pkey index which is stored at index 0 in the slave's virtual pkey table (this is the current behavior). This change is required to support cloud computing, where the paravirtualized index of the default pkey is moved to index 1 or higher. The pkey at paravirtualized index 0 is used for the default IPoIB interface created by the VF. Its possible for the pkey value at paravirtualized index 0 to be invalid (zero) at VF probe time (pkey index 0 is mapped to real pkey index 127, which contains pkey = 0). At some point after the VF probe, the cloud computing interface at the hypervisor maps virtual index 0 for the VF to the pkey index containing the pkey that IPoIB will use in its operation. However, when the tunnel QP is created, the pkey at the slave's virtual index 0 is still mapped to the invalid pkey index, so tunnel QP creation fails. This commit causes the hypervisor to search for the default pkey in the slave's pkey table -- and this pkey is present in the table (at index > 0) at tunnel QP creation time, so that the tunnel QP creation will succeed.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-fixes Samuel Ortiz <[email protected]> says: 'This is the second NFC fixes pull request for 3.11. We have: - A build failure fix for the NCI SPI transport layer due to a missing CRC_CCITT Kconfig dependency. - 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 into CMD_FW_DOWNLOAD." Signed-off-by: John W. Linville <[email protected]>

2013-07-31mwifiex: check for bss_role instead of bss_mode for STA operationsAvinash Patil2-4/+6
This patch fixes an issue wherein association would fail on P2P interfaces. This happened because we are checking priv->mode against NL80211_IFTYPE_STATION. While this check is correct for infrastructure stations, it would fail P2P clients for which mode is NL80211_IFTYPE_P2P_CLIENT. Better check would be bss_role which has only 2 values: STA/AP.
