2014-02-21s390/pci/dma: use correct segment boundary sizeGerald Schaefer1-3/+5
The boundary size for iommu_area_alloc() is currently set to a constant value. This is wrong, we shouldn't use a constant value but rather the return value of dma_get_seg_boundary(), since a device driver can override the default.

Fixes to 2 Capella light sensor drivers where the units of the integration time reported to userspace were out be a factor of a thousand. These patches are as large as they are purely due to a variable rename tied up with the incorrect scale. The actual change is only a couple of lines. 1 patch dropping L3GD20H from the st gyroscope driver. It never actually worked as the address set is different from any others supported by the driver currently. An additional patch enables correct support for this part but is too large to sensibly apply as a fix to some support that never actually allowed the driver to be successfully probed on this part.

2014-02-20tcm_qla2xxx: Perform configfs depend/undepend for base_tpgNicholas Bellinger2-14/+61
This patch performs configfs_depend_item() during TPG enable for base_tpg (eg: non-NPIV) ports, and configfs_undepend_item() during TPG disable for base_tpg. This is done to ensure that any attempt to configfs rmdir a base_tpg with active NPIV ports will fail with -EBUSY, until all associated NPIV ports have been explicitly shutdown and base_tpg disabled. Note that the actual configfs_[un]depend_item() is done from seperate process context, as these are not intended to be called directly from configfs callbacks.

2014-02-20quota: Fix race between dqput() and dquot_scan_active()Jan Kara1-3/+11
Currently last dqput() can race with dquot_scan_active() causing it to call callback for an already deactivated dquot. The race is as follows: CPU1 CPU2 dqput() spin_lock(&dq_list_lock); if (atomic_read(&dquot->dq_count) > 1) { - not taken if (test_bit(DQ_ACTIVE_B, &dquot->dq_flags)) { spin_unlock(&dq_list_lock); ->release_dquot(dquot); if (atomic_read(&dquot->dq_count) > 1) - not taken dquot_scan_active() spin_lock(&dq_list_lock); if (!test_bit(DQ_ACTIVE_B, &dquot->dq_flags)) - not taken atomic_inc(&dquot->dq_count); spin_unlock(&dq_list_lock); - proceeds to release dquot ret = fn(dquot, priv); - called for inactive dquot Fix the problem by making sure possible ->release_dquot() is finished by the time we call the callback and new calls to it will notice reference dquot_scan_active() has taken and bail out.

2014-02-20udf: Fix data corruption on file type conversionJan Kara2-2/+13
UDF has two types of files - files with data stored in inode (ICB in UDF terminology) and files with data stored in external data blocks. We convert file from in-inode format to external format in udf_file_aio_write() when we find out data won't fit into inode any longer. However the following race between two O_APPEND writes can happen: CPU1 CPU2 udf_file_aio_write() udf_file_aio_write() down_write(&iinfo->i_data_sem); checks that i_size + count1 fits within inode => no need to convert up_write(&iinfo->i_data_sem); down_write(&iinfo->i_data_sem); checks that i_size + count2 fits within inode => no need to convert up_write(&iinfo->i_data_sem); generic_file_aio_write() - extends file by count1 bytes generic_file_aio_write() - extends file by count2 bytes Clearly if count1 + count2 doesn't fit into the inode, we overwrite kernel buffers beyond inode, possibly corrupting the filesystem as well. Fix the problem by acquiring i_mutex before checking whether write fits into the inode and using __generic_file_aio_write() afterwards which puts check and write into one critical section.

2014-02-20net: sctp: Potentially-Failed state should not be reached from unconfirmed stateMatija Glavinic Pecotic1-3/+4
In current implementation it is possible to reach PF state from unconfirmed. We can interpret sctp-failover-02 in a way that PF state is meant to be reached only from active state, in the end, this is when entering PF state makes sense. Here are few quotes from sctp-failover-02, but regardless of these, same understanding can be reached from whole section 5: Section 5.1, quickfailover guide: "The PF state is an intermediate state between Active and Failed states." "Each time the T3-rtx timer expires on an active or idle destination, the error counter of that destination address will be incremented. When the value in the error counter exceeds PFMR, the endpoint should mark the destination transport address as PF." There are several concrete reasons for such interpretation. For start, rfc4960 does not take into concern quickfailover algorithm. Therefore, quickfailover must comply to 4960. Point where this compliance can be argued is following behavior: When PF is entered, association overall error counter is incremented for each missed HB. This is contradictory to rfc4960, as address, while in unconfirmed state, is subjected to probing, and while it is probed, it should not increment association overall error counter. This has as a consequence that we might end up in situation in which we drop association due path failure on unconfirmed address, in case we have wrong configuration in a way: Association.Max.Retrans == Path.Max.Retrans. Another reason is that entering PF from unconfirmed will cause a loss of address confirmed event when address is once (if) confirmed. This is fine from failover guide point of view, but it is not consistent with behavior preceding failover implementation and recommendation from 4960: 5.4. Path Verification Whenever a path is confirmed, an indication MAY be given to the upper layer.

Above situation cause fec tx interrupt lost and fec MAC don't do CRC checksum. The patch fix the potential issue.

Bug introduced by commit 7d442fab0a67 ("ipv4: Cache dst in tunnels"). Because sit code does not call ip_tunnel_init(), the dst_cache was not initialized. CC: Tom Herbert <[email protected]> Signed-off-by: Nicolas Dichtel <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2014-02-20iwlwifi: dvm: clear IWL_STA_UCODE_INPROGRESS when assoc failsEmmanuel Grumbach1-0/+1
We set IWL_STA_UCODE_INPROGRESS flag when we add a station and clear it when we send the LQ command for it. But the LQ command is sent only when the association succeeds. If the association doesn't succeed, we would leave this flag set and that wouldn't indicate the station entry as vacant.

2014-02-20SELinux: bigendian problems with filename trans rulesEric Paris1-4/+4
When writing policy via /sys/fs/selinux/policy I wrote the type and class of filename trans rules in CPU endian instead of little endian. On x86_64 this works just fine, but it means that on big endian arch's like ppc64 and s390 userspace reads the policy and converts it from le32_to_cpu. So the values are all screwed up. Write the values in le format like it should have been to start.

2014-02-20usb: phy: msm: fix compilation errors when !CONFIG_PM_SLEEPJosh Cartwright1-31/+26
Both the PM_RUNTIME and PM_SLEEP callbacks call into the common msm_otg_{suspend,resume} routines, however these routines are only being built when CONFIG_PM_SLEEP. In addition, msm_otg_{suspend,resume} also depends on msm_hsusb_config_vddcx(), which is only built when CONFIG_PM_SLEEP. Fix the CONFIG_PM_RUNTIME, !CONFIG_PM_SLEEP case by changing the preprocessor conditional, and moving msm_hsusb_config_vddcx(). While we're here, eliminate the CONFIG_PM conditional for setting up the dev_pm_ops. This address the following errors Russell King has hit doing randconfig builds: drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_suspend': drivers/usb/phy/phy-msm-usb.c:1691:2: error: implicit declaration of function 'msm_otg_suspend' drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_resume': drivers/usb/phy/phy-msm-usb.c:1699:2: error: implicit declaration of function 'msm_otg_resume' Cc: Ivan T.

2014-02-20usb: gadget: fix NULL pointer dereferenceAndrzej Pietrasiewicz1-1/+6
Fix possible NULL pointer dereference introduced in commit 219580e (usb: f_fs: check quirk to pad epout buf size when not aligned to maxpacketsize) In cases we do wait with: wait_event_interruptible(epfile->wait, (ep = epfile->ep)); for endpoint to be enabled, functionfs_bind() has not been called yet and epfile->ffs->gadget is still NULL and the automatic variable 'gadget' has been initialized with NULL at the point of its definition. Later on it is used as a parameter to: usb_ep_align_maybe(gadget, ep->ep, len) which in turn dereferences it. This patch fixes it by moving the actual assignment to the local 'gadget' variable after the potential waiting has completed.
