2016-07-13mpt3sas: avoid mpt3sas_transport_port_add NULL parent_devJoe Lawrence1-0/+5
If _scsih_sas_host_add's call to mpt3sas_config_get_sas_iounit_pg0 fails, ioc->sas_hba.parent_dev may be left uninitialized. A later device probe could invoke mpt3sas_transport_port_add which will call sas_port_alloc_num [scsi_transport_sas] with a NULL parent_dev pointer.

2016-07-13mpt3sas: set num_phys after allocating phy[] spaceJoe Lawrence1-9/+11
In _scsih_sas_host_add, the number of HBA phys are determined and then later used to allocate an array of struct _sas_phy's. If the routine sets ioc->sas_hba.num_phys, but then fails to allocate the ioc->sas_hba.phy array (by kcalloc error or other intermediate error/exit path), ioc->sas_hba is left in a dangerous state: all readers of ioc->sas_hba.phy[] do so by indexing it from 0..ioc->sas_hba.num_phys without checking that the space was ever allocated. Modify _scsih_sas_host_add to set ioc->sas_hba.num_phys only after successfully allocating ioc->sas_hba.phy[].

2016-07-11tmpfs: fix regression hang in fallocate undoHugh Dickins1-3/+5
The well-spotted fallocate undo fix is good in most cases, but not when fallocate failed on the very first page. index 0 then passes lend -1 to shmem_undo_range(), and that has two bad effects: (a) that it will undo every fallocation throughout the file, unrestricted by the current range; but more importantly (b) it can cause the undo to hang, because lend -1 is treated as truncation, which makes it keep on retrying until every page has gone, but those already fully instantiated will never go away. Big thank you to xfstests generic/269 which demonstrates this.

As of Xen 4.7 PV CPUID doesn't expose either of CPUID[1].ECX[7] and CPUID[0x80000007].EDX[7] anymore, causing the driver to fail to load on both Intel and AMD systems. Doing any kind of hardware capability checks in the driver as a prerequisite was wrong anyway: With the hypervisor being in charge, all such checking should be done by it. If ACPI data gets uploaded despite some missing capability, the hypervisor is free to ignore part or all of that data. Ditch the entire check_prereq() function, and do the only valid check (xen_initial_domain()) in the caller in its place.

2016-07-08xenbus: don't bail early from xenbus_dev_request_and_reply()Jan Beulich1-3/+0
xenbus_dev_request_and_reply() needs to track whether a transaction is open. For XS_TRANSACTION_START messages it calls transaction_start() and for XS_TRANSACTION_END messages it calls transaction_end(). If sending an XS_TRANSACTION_START message fails or responds with an an error, the transaction is not open and transaction_end() must be called. If sending an XS_TRANSACTION_END message fails, the transaction is still open, but if an error response is returned the transaction is closed. Commit 027bd7e89906 ("xen/xenbus: Avoid synchronous wait on XenBus stalling shutdown/restart") introduced a regression where failed XS_TRANSACTION_START messages were leaving the transaction open. This can cause problems with suspend (and migration) as all transactions must be closed before suspending. It appears that the problematic change was added accidentally, so just remove it.

When proc_pid_attr_write() was changed to use memdup_user apparmor's (interface violating) assumption that the setprocattr buffer was always a single page was violated. The size test is not strictly speaking needed as proc_pid_attr_write() will reject anything larger, but for the sake of robustness we can keep it in. SMACK and SELinux look safe to me, but somebody else should probably have a look just in case.

From Omar. - A writeback fix from Tahsin, fixing a case where we'd call ihold() with a zero ref count inode" * 'for-linus' of git://git.kernel.dk/linux-block: block: fix use-after-free in sys_ioprio_get() writeback: inode cgroup wb switch should not call ihold() xen-blkfront: save uncompleted reqs in blkfront_resume()

2016-07-07arm64: kernel: Save and restore UAO and addr_limit on exception entryJames Morse4-3/+22
If we take an exception while at EL1, the exception handler inherits the original context's addr_limit and PSTATE.UAO values. To be consistent always reset addr_limit and PSTATE.UAO on (re-)entry to EL1. This prevents accidental re-use of the original context's addr_limit. Based on a similar patch for arm from Russell King.

2016-07-07xenbus: don't BUG() on user mode induced conditionJan Beulich1-6/+8
Inability to locate a user mode specified transaction ID should not lead to a kernel crash. For other than XS_TRANSACTION_START also don't issue anything to xenbus if the specified ID doesn't match that of any active transaction.
