2011-09-18drm/radeon/kms: Make GPU/CPU page size handling consistent in blit code (v2)Alex Deucher7-24/+34
The BO blit code inconsistenly handled the page size. This wasn't an issue on system with 4k pages since the GPU's page size is 4k as well. Switch the driver blit callbacks to take num pages in GPU page units. Fixes lemote mipsel systems using AMD rs780/rs880 chipsets. v2: incorporate suggestions from Michel.

2011-09-18Btrfs: only clear the need lookup flag after the dentry is setupJosef Bacik1-2/+11
We can race with readdir and the RCU path walking stuff. This is because we clear the need lookup flag before actually instantiating the inode. This will lead the RCU path walk stuff to find a dentry it thinks is valid without a d_inode attached. So instead unhash the dentry when we first start the lookup, and then clear the flag after we've instantiated the dentry so we're garunteed to either try the slow lookup, or have the d_inode set properly.

Since the d_off in the first dirent for "." (that originates from the 4th argument "offset" of filldir() for the 2nd dirent for "..") is wrongly assigned in btrfs_real_readdir(), telldir returns same offset for different locations. | # mkfs.btrfs /dev/sdb1 | # mount /dev/sdb1 fs0 | # cd fs0 | # touch file0 file1 | # ../test | telldir: 0 | readdir: d_off = 2, d_name = "." | telldir: 2 | readdir: d_off = 2, d_name = ".." | telldir: 2 | readdir: d_off = 3, d_name = "file0" | telldir: 3 | readdir: d_off = 2147483647, d_name = "file1" | telldir: 2147483647 To fix this problem, pass filp->f_pos (which is loff_t) instead. | # ../test | telldir: 0 | readdir: d_off = 1, d_name = "." | telldir: 1 | readdir: d_off = 2, d_name = ".." | telldir: 2 | readdir: d_off = 3, d_name = "file0" : At the moment the "offset" for "." is unused because there is no preceding dirent, however it is better to pass filp->f_pos to follow grammatical usage.

2011-09-18sched/rt: Migrate equal priority tasks to available CPUsShawn Bohrer1-2/+2
Commit 43fa5460fe60dea5c610490a1d263415419c60f6 ("sched: Try not to migrate higher priority RT tasks") also introduced a change in behavior which keeps RT tasks on the same CPU if there is an equal priority RT task currently running even if there are empty CPUs available. This can cause unnecessary wakeup latencies, and can prevent the scheduler from balancing all RT tasks across available CPUs. This change causes an RT task to search for a new CPU if an equal priority RT task is already running on wakeup. Lower priority tasks will still have to wait on higher priority tasks, but the system should still balance out because there is always the possibility that if there are both a high and low priority RT tasks on a given CPU that the high priority task could wakeup while the low priority task is running and force it to search for a better runqueue.

2011-09-17ipv6: don't use inetpeer to store metrics for routes.Yan, Zheng1-11/+22
Current IPv6 implementation uses inetpeer to store metrics for routes. The problem of inetpeer is that it doesn't take subnet prefix length in to consideration. If two routes have the same address but different prefix length, they share same inetpeer. So changing metrics of one route also affects the other. The fix is to allocate separate metrics storage for each route. Signed-off-by: Zheng Yan <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2011-09-16iscsi-target: Fix sendpage breakage with proper padding+DataDigest iovec offsetsNicholas Bellinger1-7/+15
This patch fixes a bug in the iscsit_fe_sendpage_sg() transmit codepath that was originally introduced with the v3.1 iscsi-target merge that incorrectly uses hardcoded cmd->iov_data_count values to determine cmd->iov_data[] offsets for extra outgoing padding and DataDigest payload vectors. This code is obviously incorrect for the DataDigest enabled case with sendpage offload, and this fix ensures correct operation for padding + DataDigest, padding only, and DataDigest only cases. The bug was introduced during a pre-merge change in iscsit_fe_sendpage_sg() to natively use struct scatterlist instead of the legacy v3.0 struct se_mem logic.

2011-09-16iscsi-target: Disable markers + remove dangerous local scope array usageNicholas Bellinger2-243/+7
This patch makes iscsi-target explictly disable OFMarker=Yes and IFMarker=yes parameter key usage during iscsi login by setting IFMarkInt_Reject and OFMarkInt_Reject values in iscsi_enforce_integrity_rules() to effectively disable iscsi marker usage. With this patch, an initiator proposer asking to enable either marker parameter keys will be issued a 'No' response, and the target sets OFMarkInt + IFMarkInt parameter key response to 'Irrelevant'. With markers disabled during iscsi login, this patch removes the problematic on-stack local-scope array for marker intervals in iscsit_do_rx_data() + iscsit_do_tx_data(), and other related marker code in iscsi_target_util.c.

2011-09-16target: Skip non hex characters for VPD=0x83 NAA IEEE Registered ExtendedNicholas Bellinger1-2/+33
This patch adds target_parse_naa_6h_vendor_specific() to address a bug where the conversion of PRODUCT SERIAL NUMBER to use hex2bin() in target_emulate_evpd_83() was not doing proper isxdigit() checking. This conversion of the vpd_unit_serial configifs attribute is done while generating a VPD=0x83 NAA IEEE Registered Extended DESIGNATOR format's 100 bits of unique VENDOR SPECIFIC IDENTIFIER + VENDOR SPECIFIC IDENTIFIER EXTENSION area. This patch allows vpd_unit_serial (VPD=0x80) and the T10 Vendor ID DESIGNATOR format (VPD=0x83) to continue to use free-form variable length ASCII values, and now skips any non hex characters for fixed length NAA IEEE Registered Extended DESIGNATOR format (VPD=0x83) requring the binary conversion. This was originally reported by Martin after the v3.1-rc1 change to use hex2bin() in commit 11650b859681e03fdbf26277fcfc5f1f62186703 where the use of non hex characters in vpd_unit_serial generated different values than the original v3.0 internal hex -> binary code. This v3.1 change caused a problem with filesystems who write a NAA DESIGNATOR onto it's ondisk metadata, and this patch will (again) change existing values to ensure that non hex characters are not included in the fixed length NAA DESIGNATOR. Note this patch still expects vpd_unit_serial to be set via existing userspace methods of uuid generation, and does not do strict formatting via configfs input. The original bug report and thread can be found here: NAA breakage http://www.spinics.net/lists/target-devel/msg00477.html The v3.1-rc1 formatting of VPD=0x83 w/o this patch: VPD INQUIRY: Device Identification page Designation descriptor number 1, descriptor length: 20 designator_type: NAA, code_set: Binary associated with the addressed logical unit NAA 6, IEEE Company_id: 0x1405 Vendor Specific Identifier: 0xffde35ebf Vendor Specific Identifier Extension: 0x3092f498ffa820f9 [0x6001405ffde35ebf3092f498ffa820f9] Designation descriptor number 2, descriptor length: 56 designator_type: T10 vendor identification, code_set: ASCII associated with the addressed logical unit vendor id: LIO-ORG vendor specific: IBLOCK:ffde35ec-3092-4980-a820-917636ca54f1 The v3.1-final formatting of VPD=0x83 w/ this patch: VPD INQUIRY: Device Identification page Designation descriptor number 1, descriptor length: 20 designator_type: NAA, code_set: Binary associated with the addressed logical unit NAA 6, IEEE Company_id: 0x1405 Vendor Specific Identifier: 0xffde35ec3 Vendor Specific Identifier Extension: 0x924980a82091763 [0x6001405ffde35ec30924980a82091763] Designation descriptor number 2, descriptor length: 56 designator_type: T10 vendor identification, code_set: ASCII associated with the addressed logical unit vendor id: LIO-ORG vendor specific: IBLOCK:ffde35ec-3092-4980-a820-917636ca54f1 (v2: Fix parsing code to dereference + check for string terminator instead of null pointer to ensure a zeroed payload for vpd_unit_serial less than 100 bits of NAA DESIGNATOR VENDOR SPECIFIC area.

The impact is that after a STA disconnects *or* when for any reason a regulatory domain change happens the beacon hint flag is not cleared therefore preventing future beacon hints to be learned. This is important as a regulatory domain change or a restore of regulatory settings would set back the passive scan and no-ibss flags on the channel. This is the right place to do this given that it covers any regulatory domain change. Cc: [email protected] Reviewed-by: Luis R.

2011-09-16ibmveth: Fix checksum offload failure handlingAnton Blanchard1-11/+20
Fix a number of issues in ibmveth_set_csum_offload: - set_attr6 and clr_attr6 may be used uninitialised - We store the result of the IPV4 checksum change in ret but overwrite it in a couple of places before checking it again later. Add ret4 to make it obvious what we are doing. - We weren't clearing the NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM flags if the enable of that hypervisor feature failed.

2011-09-16ibmveth: Checksum offload is always disabledAnton Blanchard1-1/+1
Commit b9367bf3ee6d (net: ibmveth: convert to hw_features) reversed a check in ibmveth_set_csum_offload that results in checksum offload never being enabled. Signed-off-by: Anton Blanchard <[email protected]> Cc: <[email protected]> # 3.0+ Signed-off-by: David S. Miller <[email protected]>
2011-09-16ibmveth: Fix issue with DMA mapping failureAnton Blanchard1-5/+5
descs[].fields.address is 32bit which truncates any dma mapping errors so dma_mapping_error() fails to catch it. Use a dma_addr_t to do the comparison. With this patch I was able to transfer many gigabytes of data with IOMMU fault injection set at 10% probability.

2011-09-16ibmveth: Fix DMA unmap errorBrian King1-1/+6
Commit 6e8ab30ec677 (ibmveth: Add scatter-gather support) introduced a DMA mapping API inconsistency resulting in dma_unmap_page getting called on memory mapped via dma_map_single. This was seen when CONFIG_DMA_API_DEBUG was enabled. Fix up this API usage inconsistency.
