* qed*: Utilize Firmware 8.15.3.0Mintz, Yuval2017-03-135-64/+6
| | | | | | | | | | | | | | | | | | | | | | | | | This patch advances the qed* drivers into using the newer firmware - This solves several firmware bugs, mostly related [but not limited to] various init/deinit issues in various offloaded protocols. It also introduces a major 4-Cached SGE change in firmware, which can be seen in the storage drivers' changes. In addition, this firmware is required for supporting the new QL41xxx series of adapters; While this patch doesn't add the actual support, the firmware contains the necessary initialization & firmware logic to operate such adapters [actual support would be added later on].

* sched/core: Remove the tsk_cpus_allowed() wrapperIngo Molnar2017-03-022-2/+2
| | | | | | | | | | | | | | | | | So the original intention of tsk_cpus_allowed() was to 'future-proof' the field - but it's pretty ineffectual at that, because half of the code uses ->cpus_allowed directly ... Also, the wrapper makes the code longer than the original expression! So just get rid of it. This also shrinks <linux/sched.h> a bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apart from adding the helper function itself, the rest of the kernel is converted mechanically using: git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/' git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/' This is needed for a later patch that hooks into the helper, but might be a worthwhile cleanup on its own.

It is very straight forward and can limit the abosolute numbers of common rdma constructs used by different cgroups. - kernel/cgroup.c got too chubby and disorganized. Created kernel/cgroup/ subdirectory and moved all cgroup related files under kernel/ there and reorganized the core code. This hurts for backporting patches but was long overdue. - cgroup v2 process listing reimplemented so that it no longer depends on allocating a buffer large enough to cache the entire result to sort and uniq the output. v2 has always mangled the sort order to ensure that users don't depend on the sorted output, so this shouldn't surprise anybody. This makes the pid listing functions use the same iterators that are used internally, which have to have the same iterating capabilities anyway. - perf cgroup filtering now works automatically on cgroup v2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the "ib_virt" cap is set, configuration of port capabilities need to be done through mlx5_core_modify_hca_vport_context. Since modify_hca_vport_context accepts mask and value, there is no need to read the port capabilities and calculate the new cap values so we avoid the mutex when ib_virt is set.

| * | | IB/mlx4: Take source GID by index from HW GID tableTalat Batheesh2017-02-141-24/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we used the HW GID index in order to search the source GID in the software GID cached table. In some cases, for example when the MAC Address of the network interface is changed, the GID cached table saves the old-IPv6-link-local GID at the end of the table. When returning the old MAC address, the software GID cached table tries to add the new IPv6-link-local GID, and when it identifies that the GID already exists, the software GID cached does not add it. Thus a mismatch occurs between the HW and the SW GID tables. It resulted with sending traffic with the wrong source GID. This commit fixes the issue by taking both from the HW table. The problem can be reproduced with the following scenario: Client: # ifconfig ens6 2.2.2.5 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ifconfig ens6 hw ether f4:52:14:61:a0:71 # ifconfig ens6 inet6 del 2001:0db8:0:f101::5/64 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ucmatose -f ipv6 -b 2001:0db8:0:f101::5 -s 2001:0db8:0:f101::6 -p 20156 Server: # ucmatose -f ipv6 -b 2001:0db8:0:f101::6 -p 20156 Fixes: 4c3eb3ca1396 ('IB/mlx4: Add VLAN support for IBoE') Signed-off-by: Talat Batheesh <talatb@mellanox.com> Reviewed-by: Maor Gottlieb <maorg@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>

Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers. This patch doesn't add any new functionality.
