2011-10-30[SCSI] mpt2sas: New feature - Fast Load Supportnagalakshmi.nandigama@lsi.com
New feature Fast Load Support. (1)Asynchronous SCSI scanning: This will allow the drivers to scan for devices in parallel while other device drivers are loading at the same time. This will improve the amount of time it takes for the OS to load. (2) Reporting Devices while port enable is active: This feature will allow devices to be reported to OS immediately while port enable is active. The previous implementation waits for port enable to complete, and then report devices. This feature is only enabled on IT firmware configurations when there are no boot device configured in BIOS Configuration Utility, else the driver will wait till port enable completes reporting devices. For IR firmware, this feature is turned off. This feature is to address large SAS topologies (>100 drives) when the boot OS is using onboard SATA device, in other words, the boot devices is not connected to our controller. (3) Scanning for devices after diagnostic reset completes: A new routine _scsih_scan_start is added. This will scan the expander pages, IR pages, and sas device pages, then reporting new devices to SCSI Mid layer. It seems the driver is not supporting adding devices while diagnostic reset is active. Apparently this is due to the sanity checks on ioc->shost_recovery flag throughout the context of kernel work thread FIFO, and the mpt2sas_fw_work.

2011-10-30ipv6: fix route lookup in addrconf_prefix_rcv()Andreas Hofmeister
The route lookup to find a previously auto-configured route for a prefixes used to use rt6_lookup(), with the prefix from the RA used as an address. However, that kind of lookup ignores routing tables, the prefix length and route flags, so when there were other matching routes, even in different tables and/or with a different prefix length, the wrong route would be manipulated. Now, a new function "addrconf_get_prefix_route()" is used for the route lookup, which searches in RT6_TABLE_PREFIX and takes the prefix-length and route flags into account.

2011-10-30bonding: eliminate bond_close race conditionsJay Vosburgh
This patch resolves two sets of race conditions. Mitsuo Hayasaka <mitsuo.hayasaka.hu@hitachi.com> reported the first, as follows: The bond_close() calls cancel_delayed_work() to cancel delayed works. It, however, cannot cancel works that were already queued in workqueue. The bond_open() initializes work->data, and proccess_one_work() refers get_work_cwq(work)->wq->flags. The get_work_cwq() returns NULL when work->data has been initialized. Thus, a panic occurs. He included a patch that converted the cancel_delayed_work calls in bond_close to flush_delayed_work_sync, which eliminated the above problem. His patch is incorporated, at least in principle, into this patch. In this patch, we use cancel_delayed_work_sync in place of flush_delayed_work_sync, and also convert bond_uninit in addition to bond_close. This conversion to _sync, however, opens new races between bond_close and three periodically executing workqueue functions: bond_mii_monitor, bond_alb_monitor and bond_activebackup_arp_mon. The race occurs because bond_close and bond_uninit are always called with RTNL held, and these workqueue functions may acquire RTNL to perform failover-related activities. If bond_close or bond_uninit is waiting in cancel_delayed_work_sync, deadlock occurs. These deadlocks are resolved by having the workqueue functions acquire RTNL conditionally. If the rtnl_trylock() fails, the functions reschedule and return immediately. For the cases that are attempting to perform link failover, a delay of 1 is used; for the other cases, the normal interval is used (as those activities are not as time critical). Additionally, the bond_mii_monitor function now stores the delay in a variable (mimicing the structure of activebackup_arp_mon). Lastly, all of the above renders the kill_timers sentinel moot, and therefore it has been removed.

2011-10-30qlcnic: fix beacon and LED test.Sucheta Chakraborty
o Updated version number to 5.0.25 o Do not hold onto RESETTING_BIT for entire duration of LED/ beacon test. Instead, just checking for RESETTING_BIT not set before sending config_led command down to card. o Take rtnl_lock instead of RESETTING_BIT for beacon test while sending config_led command down to make sure interface cannot be brought up/ down. o Allocate and free resources if interface is down before sending the config_led command. This is to make sure config_led command sending doesn't fail. o Clear QLCNIC_LED_ENABLE bit if beacon/ LED test fails to start.

2011-10-29cifs: Assume passwords are encoded according to iocharset (try #2)Shirish Pargaonkar
Re-posting a patch originally posted by Oskar Liljeblad after rebasing on 3.2. Modify cifs to assume that the supplied password is encoded according to iocharset. Before this patch passwords would be treated as raw 8-bit data, which made authentication with Unicode passwords impossible (at least passwords with characters > 0xFF). The previous code would as a side effect accept passwords encoded with ISO 8859-1, since Unicode < 0x100 basically is ISO 8859-1. Software which relies on that will no longer support password chars > 0x7F unless it also uses iocharset=iso8859-1. (mount.cifs does not care about the encoding so it will work as expected.)

2011-10-29ext4: fix race in xattr block allocation pathEric Sandeen
Ceph users reported that when using Ceph on ext4, the filesystem would often become corrupted, containing inodes with incorrect i_blocks counters. I managed to reproduce this with a very hacked-up "streamtest" binary from the Ceph tree. Ceph is doing a lot of xattr writes, to out-of-inode blocks. There is also another thread which does sync_file_range and close, of the same files. The problem appears to happen due to this race: sync/flush thread xattr-set thread ----------------- ---------------- do_writepages ext4_xattr_set ext4_da_writepages ext4_xattr_set_handle mpage_da_map_blocks ext4_xattr_block_set set DELALLOC_RESERVE ext4_new_meta_blocks ext4_mb_new_blocks if (!i_delalloc_reserved_flag) vfs_dq_alloc_block ext4_get_blocks down_write(i_data_sem) set i_delalloc_reserved_flag ... up_write(i_data_sem) if (i_delalloc_reserved_flag) vfs_dq_alloc_block_nofail In other words, the sync/flush thread pops in and sets i_delalloc_reserved_flag on the inode, which makes the xattr thread think that it's in a delalloc path in ext4_new_meta_blocks(), and add the block for a second time, after already having added it once in the !i_delalloc_reserved_flag case in ext4_mb_new_blocks The real problem is that we shouldn't be using the DELALLOC_RESERVED state flag, and instead we should be passing EXT4_GET_BLOCKS_DELALLOC_RESERVE down to ext4_map_blocks() instead of using an inode state flag. We'll fix this for now with using i_data_sem to prevent this race, but this is really not the right way to fix things.

2011-10-29i2c-au1550: increase timeout waiting for master doneManuel Lauss
Double the timeout in the loop which busy-waits for the "master-done" bit to be set. This bit indicates whether an i2c transaction has completed; on the DB1300 and DB1550 boards this timeout is slightly too short and causes transactions to the WM8731 codec to be falsely flagged as failed. The timeout itself is necessary since transactions to non-existant slaves never set this bit in the first place (and cause i2cdetect to hang). With this change the WM8731 codec on the DB1300/DB1550 boards is correctly detected and initialized.

2011-10-29i2c-designware: Support multiple cores using same ISRDirk Brandewie
Add check to make sure that the core is enabled and has outstanding interrupts. The activity bit is masked due to the fact that it will stay active even after the controller has been disabled until the contoller internal state machines have settled.

2011-10-29i2c-designware: move controller config to bus specific portion of driverDirk Brandewie
With multiple I2C adapters possible in the system each running at (possibly) different speeds we need to move the controller configuration bit field to the adapter. Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2011-10-29i2c-designware: move i2c functionality bit field to be adapter specificDirk Brandewie
The functionality of the adapter depends on the configuration of the IP block at silicon compile time and is adapter specific. Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2011-10-29i2c-designware: Move retriveving the clock speed out of core code.Dirk Brandewie
The clock frequecy supplied to the IP core is specific to a single instance of the driver. This patch makes it possible to have multiple Designware I2C cores in the system possibly running at different core frequencies.
