2017-09-22parisc: Unbreak bootloader due to gcc-7 optimizationsHelge Deller2-2/+3
gcc-7 optimizes the byte-wise accesses of get_unaligned_le32() into word-wise accesses if the 32-bit integer output_len is declared as external. This panics then the bootloader since we don't have the unaligned access fault trap handler installed during boot time. Avoid this optimization by declaring output_len as byte-aligned and thus unbreak the bootloader code. Additionally, compile the boot code optimized for size.

2017-09-22parisc: Reintroduce option to gzip-compress the kernelHelge Deller2-0/+17
By adding the feature to build the kernel as self-extracting executeable, the possibility to simply compress the kernel with gzip was lost. This patch now reintroduces this possibilty again and leaves it up to the user to decide how the kernel should be built. The palo bootloader is able to natively load both formats.

2017-09-22apparmor: fix apparmorfs DAC access permissionsJohn Johansen1-4/+4
The DAC access permissions for several apparmorfs files are wrong. .access - needs to be writable by all tasks to perform queries the others in the set only provide a read fn so should be read only. With policy namespace virtualization all apparmor needs to control the permission and visibility checks directly which means DAC access has to be allowed for all user, group, and other.

2017-09-22bnxt_re: Remove RTNL lock dependency in bnxt_re_query_portSomnath Kotur3-8/+9
When there is a NETDEV_UNREGISTER event, bnxt_re driver calls ib_unregister_device() (RTNL lock held). ib_unregister_device attempts to flush a worker queue scheduled by ib_core and that queue might have a pending ib_query_port(). ib_query_port in turn calls bnxt_re_query_port(), which while querying the link speed using ib_get_eth_speed(), tries to acquire the rtnl_lock() which was already held by NETDEV_UNREGISTER. Fixing the issue by removing the link speed query from bnxt_re_query_port() Now the speed is queried post a successful ib_register_device or whenever there is a NETDEV_CHANGE event.

2017-09-22bnxt_re: Fix race between the netdev register and unregister eventsSomnath Kotur2-5/+15
Upon receipt of the NETDEV_REGISTER event from the netdev notifier chain, the IB stack registration is spawned off to a workqueue since that also requires an rtnl lock. There could be 2 kinds of races between the NETDEV_REGISTER and the NETDEV_UNREGISTER event handling. a)The NETDEV_UNREGISTER event is received in rapid succession after the NETDEV_REGISTER event even before the work queue got a chance to run. b)The NETDEV_UNREGISTER event is received while the workqueue that handles registration with the IB stack is still in progress. Handle both the races with a bit flag that is set just before the work item is queued and cleared in the workqueue after the event is handled just before the workqueue item is freed. While adding the new flag, it was noted that the flags are all used in *_bit() operations which expect a bit number and not a literal constant with a bit set. So change the numbers to be bit numbers.

Commit 24587380f61d ("parisc: Add MADV_HWPOISON and MADV_SOFT_OFFLINE") added the necessary constants to handle hardware-poisoning. Those were needed to support the page deallocation feature from firmware. But I completely missed to add the relevant fault handler code. This now showed up when I ran the madvise07 testcase from the Linux Test Project, which failed with a kernel BUG at arch/parisc/mm/fault.c:320.

2017-09-22i40iw: Prevent multiple netdev event notifier registrationsShiraz Saleem3-19/+20
Netdev event notifier registration/de-registration is not synchronized with a lock and there is a possibility of a duplicate registration of notifier before the unregister completes. Register netdev event notifiers during module init and de-register them at module exit. This avoids the need to tie the registration to first netdev client interface open and de-registration to last client interface close and the synchronization to achieve it. This also fixes a crash due to duplicate registration.

2017-09-22IB/mlx5: fix debugfs cleanupSudip Mukherjee1-3/+3
If delay_drop_debugfs_init() fails in any of the operations to create debugfs, it is calling delay_drop_debugfs_cleanup() as part of its cleanup. But delay_drop_debugfs_cleanup() checks for 'dbg' and since we have not yet pointed 'dbg' to the debugfs we need to cleanup, the cleanup fails and we are left with stray debugfs elements and also a memory leak.

2017-09-22IB/ocrdma: fix incorrect fall-through on switch statementColin Ian King1-0/+3
In the case where mbox_status is OCRDMA_MBX_STATUS_FAILED and add_status is OCRDMA_MBX_STATUS_FAILED err_num is assigned -EAGAIN however the case OCRDMA_MBX_STATUS_FAILED is missing a break and falls through to the default case which then re-assigns err_num to -EFAULT. Fix this so that err_num is assigned to -EAGAIN for the add_status OCRDMA_MBX_STATUS_FAILED case and -EFAULT otherwise.
