* Bluetooth: Fix bug with filter in service discovery optimizationMarcel Holtmann2014-12-171-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The optimization for filtering out extended inquiry results, advertising reports or scan response data based on provided UUID list has a logic bug. In case no match is found in the advertising data, the scan response is ignored and not checked against the filter. This will lead to events being filtered wrongly. Change the code to actually only drop the events when the scan response data is not present. If it is present, it needs to be checked against the provided filter. The patch is a bit more complex than it needs to be. That is because it also fixes this compiler warning that some gcc versions produce. CC net/bluetooth/mgmt.o net/bluetooth/mgmt.c: In function ‘mgmt_device_found’: net/bluetooth/mgmt.c:7028:7: warning: ‘match’ may be used uninitialized in this function [-Wmaybe-uninitialized] bool match; ^ It seems that gcc can not clearly figure out the context of the match variable. So just change the branches for the extended inquiry response and advertising data around so that it is clear.

| | * Bluetooth: Fix mgmt response status when removing adapterJohan Hedberg2014-12-121-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an adapter is removed (hci_unregister_dev) any pending mgmt commands for that adapter should get the appropriate INVALID_INDEX response. Since hci_unregister_dev() calls hci_dev_do_close() first that'd so far have caused "not powered" responses to be sent. Skipping the HCI_UNREGISTER case in mgmt_powered() is also not a solution since before reaching the mgmt_index_removed() stage any hci_conn callbacks (e.g. used by pairing) will get called, thereby causing "disconnected" status responses to be sent. The fix that covers all scenarios is to handle both INVALID_INDEX and NOT_POWERED responses through the mgmt_powered() function. The INVALID_INDEX response sending from mgmt_index_removed() is left untouched since there are a couple of places not related to powering off or removing an adapter that call it (e.g. configuring a new bdaddr).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we're in the AUTO_OFF stage the powered_update_hci() function is responsible for doing the updates to the HCI state that were not done during the actual mgmt command handlers. One of the updates needing done is for BR/EDR SC support. This patch adds the missing HCI command for SC support to the powered_update_hci() function.

It is the later pulled before the real GRE header is constructed. The inner mac was thus set differently in nbma case: the GRE header has been pushed by neighbor layer, and mac header points to beginning of the temporary gre header (set by dev_queue_xmit). Now that the offloads expect mac header to point to the gre payload, fix the xmit patch to: - pull first the temporary gre header away - and reset mac header to point to gre payload This fixes tso to work again with nbma tunnels.

This is a discussed follow-up that, instead, extends the sock API and adds sock_kzfree_s(), which internally uses kzfree() instead of kfree() for passing the buffers back to slab. Having sock_kzfree_s() allows to keep the changes more minimal by just having a drop-in replacement instead of adding memzero_explicit() calls everywhere before sock_kfree_s(). In kzfree(), the compiler is not allowed to optimize the memset() away and thus there's no need for memzero_explicit(). Both, sock_kfree_s() and sock_kzfree_s() are wrappers for __sock_kfree_s() and call into kfree() resp. kzfree(); here, __sock_kfree_s() needs to be explicitly inlined as we want the compiler to optimize the call and condition away and thus it produces e.g. on x86_64 the _same_ assembler output for sock_kfree_s() before and after, and thus also allows for avoiding code duplication.

Specifically in the case of adding a new leaf that triggers a new node to be added that takes the place of the old node. The result is a trie where the 1 child tnode is on one side and one leaf is on the other which gives you a very deep trie. Below is the script I used to generate a trie on dummy0 with a 10.X.X.X family of addresses. ip link add type dummy ipval=184549374 bit=2 for i in `seq 1 23` do ifconfig dummy0:$bit $ipval/8 ipval=`expr $ipval - $bit` bit=`expr $bit \* 2` done cat /proc/net/fib_triestat Running the script before the patch: Local: Aver depth: 10.82 Max depth: 23 Leaves: 29 Prefixes: 30 Internal nodes: 27 1: 26 2: 1 Pointers: 56 Null ptrs: 1 Total size: 5 kB After applying the patch and repeating: Local: Aver depth: 4.72 Max depth: 9 Leaves: 29 Prefixes: 30 Internal nodes: 12 1: 3 2: 2 3: 7 Pointers: 70 Null ptrs: 30 Total size: 4 kB What this fix does is start the rebalance at the newly created tnode instead of at the parent tnode. This way if there is a gap between the parent and the new node it doesn't prevent the new tnode from being coalesced with any pre-existing nodes that may have been pushed into one of the new nodes child branches.

Robert reported that he has hit after roughly 40hrs of trinity an skb_under_panic() via SCTP output path (see reference). I couldn't reproduce it from here, but not using MAX_HEADER as elsewhere in other protocols might be one possible cause for this. In any case, it looks like accounting on chunks themself seems to look good as the skb already passed the SCTP output path and did not hit any skb_over_panic(). Given tunneling was enabled in his .config, the headroom would have been expanded by MAX_HEADER in this case.

While we think that these users are actually not much of concern, it has been requested to remove the arch_fast_hash() library bits that arose from [1] entirely as per recent discussion [2]. The main argument is that using it as a hash may introduce bias due to its linearity (see avalanche criterion) and thus makes it less clear (though we tried to document that) when this security/performance trade-off is actually acceptable for a general purpose library function. Lets therefore avoid any further confusion on this matter and remove it to prevent any future accidental misuse of it. For the time being, this is going to make hashing of flow keys a bit more expensive in the ovs case, but future work could reevaluate a different hashing discipline.

Since netlink sockets can be opened by any user, a local attacker would be able to easily create collisions with the DPDK-derived arch_fast_hash(), which trades off performance for security by using crc32 CPU instructions on x86_64. While it might have a legimite use case in other places, it should be avoided in netlink context, though. As rhashtable's API is very flexible, we could later on still decide on other hashing disciplines, if legitimate.

The reason for doing this is to make these bits accessible to a new function __napi_alloc_skb. In addition __alloc_rx_skb now has a new flags value that is used to determine which page frag pool to allocate from. If the SKB_ALLOC_NAPI flag is set then the NAPI pool is used. The advantage of this is that we do not have to use local_irq_save/restore when accessing the NAPI pool from NAPI context. In my test setup I saw at least 11ns of savings using the napi_alloc_skb function versus the netdev_alloc_skb function, most of this being due to the fact that we didn't have to call local_irq_save/restore. The main use case for napi_alloc_skb would be for things such as copybreak or page fragment based receive paths where an skb is allocated after the data has been received instead of before.

By doing this we can add a NAPI specific function __napi_alloc_frag that accesses a pool that is only used from softirq context. The advantage to this is that we do not need to call local_irq_save/restore which can be a significant savings. I also took the opportunity to refactor the core bits that were placed in __alloc_page_frag. First I updated the allocation to do either a 32K allocation or an order 0 page. This is based on the changes in commmit d9b2938aa where it was found that latencies could be reduced in case of failures. Then I also rewrote the logic to work from the end of the page to the start. By doing this the size value doesn't have to be used unless we have run out of space for page fragments. Finally I cleaned up the atomic bits so that we just do an atomic_sub_and_test and if that returns true then we set the page->_count via an atomic_set. This way we can remove the extra conditional for the atomic_read since it would have led to an atomic_inc in the case of success anyway.
