2016-01-31iwlwifi: pcie: add 9000 series multi queue rx DMA supportSara Sharon6-80/+322
The 9000 series introduces several changes in the device DMA operation. As the device now supports multi-queue rx, several DMA channels should be configured. The flows of providing the device with the allocated RBDs now changes as well - the device maintains a separate table of used and free table. The hardware may use the free table to feed RBDs to any queue. This requires maintaing a shared table to map returned RBDs to the original RXB - for that purpose the VID is introduced - an internal identifier of the RB placed in the lower 12 bits and returned by HW in the used data. Another change is the support of 64 bit DMA address. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2016-01-31iwlwifi: pcie: add infrastructure for multi-queue rxSara Sharon3-154/+191
The 9000 series devices will support multi rx queues. Current code has one static rx queue - change it to allocate a number of queues per the device capability (pre-9000 devices have the number of rx queues set to one). Subsequent generalizations are: Change the code to access an explicit numbered rx queue only when the queue number is known - when handling interrupt, when accessing the default queue and when iterating the queues. The rest of the functions will receive the rx queue as a pointer. Generalize the warning in allocation failure to consider the allocator status instead of a single rx queue status. Move the rx initial pool of memory buffers to be shared among all the queues and allocated to the default queue on init.

2016-01-31iwlwifi: pcie: buffer packets to avoid overflowing Tx queuesEmmanuel Grumbach2-8/+62
When the Tx queues are full above a threshold, we immediately stop the mac80211's queue to stop getting new packets. This worked until TSO was enabled. With TSO, one single packet from mac80211 can use many descriptors since a large send needs to be split into several segments. This means that stopping mac80211's queues is not enough and we also need to ensure that we don't overflow the Tx queues with one single packet from mac80211. Add code to transport layer to do just that. Stop mac80211's queue as soon as the queue is full above the same threshold as before, and keep pushing the current packet along with its segments on the queue, but check that we don't overflow. If that would happen, buffer the segments, and send them when there is room in the Tx queue again. Of course, we first need to send the buffered segments and only then, wake up mac80211's queues.

That probably should've been 5 or 6 separate branches, but by the time I'd realized how large and mixed that bag had become it had been too close to -final to play with rebasing. Some fs/namei.c cleanups there, memdup_user_nul() introduction and switching open-coded instances, burying long-dead code, whack-a-mole of various kinds, several new helpers for ->llseek(), assorted cleanups and fixes from various people, etc. One piece probably deserves special mention - Neil's lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets called without ->i_mutex and tries to avoid ever taking it. That, of course, means that it's not useful for any directory modifications, but things like getting inode attributes in nfds readdirplus are fine with that.

Commit 1f718f0f4f97 ("bonding: populate neighbour's private on enslave") undoes the fix provided by commit c2edacf80e15 ("bonding / ipv6: no addrconf for slaves separately from master") by effectively setting the slave flag after the slave has been opened. If the slave comes up quickly enough, it will go through the IPv6 addrconf before the slave flag has been set and will get a link local IPv6 address. In order to ensure that addrconf knows to ignore the slave devices on state change, set IFF_SLAVE before dev_open() during bonding enslavement.

Verbs applications will use these priorities. we found nine as a number that balances the requirements from the user and retains performance. The bypass namespace is used by verbs applications that want to bypass the kernel networking stack. The leftovers namespace is used by verbs applications and the sniffer in order to catch packets that weren't handled by any preceding rules.

These attributes are set by traversing the tree nodes by DFS and set start level and max flow tables to each priority. Start level depends on the max flow tables of the prior priorities in the tree. The leaves of the trees have max_ft set in them. Each node accumulates the max_ft of its children and set it accordingly.

2016-01-12net/mlx5_core: Connect flow tablesMaor Gottlieb3-10/+104
Flow tables from different priorities should be chained together. When a packet arrives we search for a match in the by-pass flow tables (first we search for a match in priority 0 and if we don't find a match we move to the next priority). If we can't find a match in any of the bypass flow-tables, we continue searching in the flow-tables of the next priority, which are the kernel's flow tables. Setting the miss flow table in a new flow table to be the next one in the list is performed via create flow table API. If we want to change an existing flow table, for example in order to point from an existing flow table to the new next-in-list flow table, we use the modify flow table API.

This command tells the HW to start matching packets from the assigned root flow table.

2016-01-12bonding: make mii_status sysfs node consistentJarod Wilson1-1/+1
The spew in /proc/net/bonding/bond0 uses netif_carrier_ok() to determine mii_status, while /sys/class/net/bond0/bonding/mii_status looks at curr_active_slave, which doesn't actually seem to be set sometimes when the bond actually is up. A mode 4 bond configured via ifcfg-foo files on a Red Hat Enterprise Linux system, after boot, comes up clean and functional, but the sysfs node shows mii_status of down, while proc shows up. A simple enough fix here seems to be to use the same method for determining up or down in both places, and I'd opt for the one that seems to match reality.

Dumping the FDB (invoked with a process context) or handling FDB notifications (polled periodicly in delayed work) might each entail multiple EMAD transcations due to the number of entries. While we only allow one EMAD transaction at a time, there is nothing stopping the dump and notification processing sessions from interleaving. However, this is forbidden by the hardware, so we need to make sure only one of these sessions can run at a time. Solve this by adding a mutex ('fdb_lock'), as both kernel threads can sleep while waiting for the response EMAD.

Commit e7f4dc3536a4 ("mdio: Move allocation of interrupts into core") removed the label out_err_mdiobus_register but then mistakenly jumped to out_err_alloc.

2016-01-11stmmac: Don't exit mdio registration when mdio subnode is not found in the DTSRomain Perier1-3/+5
Originally, most of the platforms using this driver did not define an mdio subnode in the devicetree. Commit e34d65 ("stmmac: create of compatible mdio bus for stmmac driver") introduced a backward compatibily issue by using of_mdiobus_register explicitly with an mdio subnode. This patch fixes the issue by calling the function mdiobus_register, when mdio subnode is not found. The driver is now compatible with both modes.

2016-01-11udp: restrict offloads to one namespaceHannes Frederic Sowa2-2/+2
udp tunnel offloads tend to aggregate datagrams based on inner headers. gro engine gets notified by tunnel implementations about possible offloads. The match is solely based on the port number. Imagine a tunnel bound to port 53, the offloading will look into all DNS packets and tries to aggregate them based on the inner data found within. This could lead to data corruption and malformed DNS packets. While this patch minimizes the problem and helps an administrator to find the issue by querying ip tunnel/fou, a better way would be to match on the specific destination ip address so if a user space socket is bound to the same address it will conflict.
