| | | | | | | | | | | | | | As the life flows, developers priorities shifts a bit. Reflect actual changes in the maintainership of IEEE 802.15.4 code: Sergey mostly stopped cared about this piece of code. Most of the work recently was done by Alexander, so put him to the MAINTAINERS file to reflect his status and to ease the life of respective patches. Also add new net/mac802154/ directory to the list of maintained files.

| * e1000e: fix test for PHY being accessible on 82577/8/9 and I217Bruce Allan2012-07-141-10/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Occasionally, the PHY can be initially inaccessible when the first read of a PHY register, e.g. PHY_ID1, happens (signified by the returned value 0xFFFF) but subsequent accesses of the PHY work as expected. Add a retry counter similar to how it is done in the generic e1000_get_phy_id(). Also, when the PHY is completely inaccessible (i.e. when subsequent reads of the PHY_IDx registers returns all F's) and the MDIO access mode must be set to slow before attempting to read the PHY ID again, the functions that do these latter two actions expect the SW/FW/HW semaphore is not already set so the semaphore must be released before and re-acquired after calling them otherwise there is an unnecessarily inordinate amount of delay during device initialization.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | SYNCH bit and IV bit of RXCW register are sticky. Before examining these bits, RXCW should be read twice to filter out one-time false events and have correct values for these bits. Incorrect values of these bits in link check logic can cause weird link stability issues if auto-negotiation fails.

* | net: cgroup: fix access the unallocated memory in netprio cgroupGao feng2012-07-161-17/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there are some out of bound accesses in netprio cgroup. now before accessing the dev->priomap.priomap array,we only check if the dev->priomap exist.and because we don't want to see additional bound checkings in fast path, so we should make sure that dev->priomap is null or array size of dev->priomap.priomap is equal to max_prioidx + 1; so in write_priomap logic,we should call extend_netdev_table when dev->priomap is null and dev->priomap.priomap_len < max_len. and in cgrp_create->update_netdev_tables logic,we should call extend_netdev_table only when dev->priomap exist and dev->priomap.priomap_len < max_len. and it's not needed to call update_netdev_tables in write_priomap, we can only allocate the net device's priomap which we change through net_prio.ifpriomap. this patch also add a return value for update_netdev_tables & extend_netdev_table, so when new_priomap is allocated failed, write_priomap will stop to access the priomap,and return -ENOMEM back to the userspace to tell the user what happend. Change From v3: 1. add rtnl protect when reading max_prioidx in write_priomap. 2. only call extend_netdev_table when map->priomap_len < max_len, this will make sure array size of dev->map->priomap always bigger than any prioidx. 3. add a function write_update_netdev_table to make codes clear. Change From v2: 1. protect extend_netdev_table by RTNL. 2. when extend_netdev_table failed,call dev_put to reduce device's refcount.

* | ixgbevf: Prevent RX/TX statistics getting reset to zeroNarendra K2012-07-161-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 4197aa7bb81877ebb06e4f2cc1b5fea2da23a7bd implements 64 bit per ring statistics. But the driver resets the 'total_bytes' and 'total_packets' from RX and TX rings in the RX and TX interrupt handlers to zero. This results in statistics being lost and user space reporting RX and TX statistics as zero. This patch addresses the issue by preventing the resetting of RX and TX ring statistics to zero.

As a result, we get a gpf when traversing the hashtable while a freed node corrupts part of the list. Nominally I would think that an mibalanced refcount was responsible for this, but I can't seem to find any obvious imbalance. What I did note however was that the two places where we create an association using sctp_primitive_ASSOCIATE (__sctp_connect and sctp_sendmsg), have failure paths which free a newly created association after calling sctp_primitive_ASSOCIATE. sctp_primitive_ASSOCIATE brings us into the sctp_sf_do_prm_asoc path, which issues a SCTP_CMD_NEW_ASOC side effect, which in turn adds a new association to the aforementioned hash table. the sctp command interpreter that process side effects has not way to unwind previously processed commands, so freeing the association from the __sctp_connect or sctp_sendmsg error path would lead to a freed association remaining on this hash table. I've fixed this but modifying sctp_[un]hash_established to use hlist_del_init, which allows us to proerly use hlist_unhashed to check if the node is on a hashlist safely during a delete. That in turn alows us to safely call sctp_unhash_established in the __sctp_connect and sctp_sendmsg error paths before freeing them, regardles of what the associations state is on the hash list. I noted, while I was doing this, that the __sctp_unhash_endpoint was using hlist_unhsashed in a simmilar fashion, but never nullified any removed nodes pointers to make that function work properly, so I fixed that up in a simmilar fashion. I attempted to test this using a virtual guest running the SCTP_RR test from netperf in a loop while running the trinity fuzzer, both in a loop. I wasn't able to recreate the problem prior to this fix, nor was I able to trigger the failure after (neither of which I suppose is suprising). Given the trace above however, I think its likely that this is what we hit. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: davej@redhat.com CC: davej@redhat.com CC: "David S.

As the bridge loop avoidance code now only considers the payload Ethernet destination, it may drop the DHCP request for clients which are claimed by other backbone gateways, because it falsely infers from the broadcast address that the right backbone gateway should havehandled the broadcast. Fix this by checking and delegating the batman-adv packet type used for transmission.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It was recently reported that moving a bonding device between network namespaces causes warnings from /proc. It turns out after the move we were trying to add and to remove the /proc/net/bonding entries from the wrong network namespace. Move the bonding /proc registration code into the NETDEV_REGISTER and NETDEV_UNREGISTER events where the proc registration and unregistration will always happen at the right time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the higher mtu sizes requiring the buffer size greater than 8192, the buffers are sent or received using multiple dma descriptors/ same descriptor with option of multi buffer handling. It was observed during tests that the driver was missing on data packets during the normal ping operations if the data buffers being used catered to jumbo frame handling. The memory barrriers are added in between preparation of dma descriptors in the jumbo frame handling path to ensure all instructions before enabling the dma are complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was observed that during multiple reboots nfs hangs. The status of receive descriptors shows that all the descriptors were in control of CPU, and none were assigned to DMA. Also the DMA status register confirmed that the Rx buffer is unavailable. This patch adds the fix for the same by adding the memory barriers to ascertain that the all instructions before enabling the Rx or Tx DMA are completed which involves the proper setting of the ownership bit in DMA descriptors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we remove a key, we put a key index which was supposed to tell the fw that we are actually removing the key. But instead the fw took that index as a valid index and messed up the SRAM of the device. This memory corruption on the device mangled the data of the SCD. The impact on the user is that SCD queue 2 got stuck after having removed keys.

So entries between Q_INDEX_DONE and Q_INDEX are those we currently process in the hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can submit to the hardware. According to that fix rt2x00usb_kick_queue(), as we need to submit RX entries that are not processed by the hardware. It worked before only for empty queue, otherwise was broken. Note that for TX queues indexes ordering are ok. We need to kick entries that have filled skb, but was not submitted to the hardware, i.e. started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull fix to common clk framework from Michael Turquette: "The previous set of common clk fixes for -rc5 left an uninitialized int which could lead to bad array indexing when switching clock parents. The issue is fixed with a trivial change to the code flow in __clk_set_parent." * tag 'clk-fixes-for-linus' of git://git.linaro.org/people/mturquette/linux: clk: fix parent validation in __clk_set_parent()

There were various options discussed on how to fix this, one being initing 'i' to clk->num_parents, but the below approach was found to be more appropriate as it also makes the 'parent validation' code simpler to read.

Several buffer overflows in NCI layer from Dan Rosenberg, and release sock OOPS'er fix from Eric Dumazet. 5) Fix WEP handling ath9k, we started using a bit the chip provides to indicate undecrypted packets but that bit turns out to be unreliable in certain configurations. Fix from Felix Fietkau. 6) Fix Kconfig dependency bug in wlcore, from Randy Dunlap. 7) New USB IDs for rtlwifi driver from Larry Finger. 8) Fix crashes in qmi_wwan usbnet driver when disconnecting, from Bjørn Mork. 9) Gianfar driver programs coalescing settings properly in single queue mode, but does not do so in multi-queue mode. Fix from Claudiu Manoil. 10) Missing module.h include in davinci_cpdma.c, from Daniel Mack. 11) Need dummy handler for IPSET_CMD_NONE otherwise we crash in ipset if we get this via nfnetlink, fix from Tomasz Bursztyka. 12) Missing RCU unlock in nfnetlink error path, also from Tomasz. 13) Fix divide by zero in igbvf when the user tries to set an RX coalescing value of 0 usecs, from Mitch A Williams. 14) We can process SCTP sacks for the wrong transport, oops. Fix from Neil Horman. 15) Remove hw IP payload checksumming from e1000e driver. This has zery value in our stack, and turning it on creates a very unintuitive restriction for users when using jumbo MTUs. Specifically, when IP payload checksums are on you cannot use both receive hashing offload and jumbo MTU.
