2014-09-11Bluetooth: Centralize disallowing SMP commands to a single placeJohan Hedberg
All the cases where we mark SMP commands as dissalowed are their respective command handlers. We can therefore simplify the code by always clearing the bit immediately after testing it. This patch converts the corresponding test_bit() call to a test_and_clear_bit() call and also removes the now unused SMP_DISALLOW_CMD macro.

2014-09-11Bluetooth: Fix ignoring unknown SMP authentication requirement bitsJohan Hedberg
The SMP specification states that we should ignore any unknown bits from the authentication requirement. We already have a define for masking out unknown bits but we haven't used it in all places so far. This patch adds usage of the AUTH_REQ_MASK to all places that need it and ensures that we don't pass unknown bits onward to other functions.

2014-09-11Bluetooth: Remove unnecessary early initialization of variableJohan Hedberg
We do nothing else with the auth variable in smp_cmd_pairing_rsp() besides passing it to tk_request() which in turn only cares about whether one of the sides had the MITM bit set. It is therefore unnecessary to assign a value to it until just before calling tk_request(), and this value can simply be the bit-wise or of the local and remote requirements.

2014-09-10rpc: xs_bind - do not bind when requesting a random ephemeral portChris Perl
When attempting to establish a local ephemeral endpoint for a TCP or UDP socket, do not explicitly call bind, instead let it happen implicilty when the socket is first used. The main motivating factor for this change is when TCP runs out of unique ephemeral ports (i.e. cannot find any ephemeral ports which are not a part of *any* TCP connection). In this situation if you explicitly call bind, then the call will fail with EADDRINUSE. However, if you allow the allocation of an ephemeral port to happen implicitly as part of connect (or other functions), then ephemeral ports can be reused, so long as the combination of (local_ip, local_port, remote_ip, remote_port) is unique for TCP sockets on the system. This doesn't matter for UDP sockets, but it seemed easiest to treat TCP and UDP sockets the same. This can allow mount.nfs(8) to continue to function successfully, even in the face of misbehaving applications which are creating a large number of TCP connections.

Pablo Neira Ayuso says: ==================== nf-next pull request The following patchset contains Netfilter/IPVS updates for your net-next tree. Regarding nf_tables, most updates focus on consolidating the NAT infrastructure and adding support for masquerading. More specifically, they are: 1) use __u8 instead of u_int8_t in arptables header, from Mike Frysinger. 2) Add support to match by skb->pkttype to the meta expression, from Ana Rey. 3) Add support to match by cpu to the meta expression, also from Ana Rey. 4) A smatch warning about IPSET_ATTR_MARKMASK validation, patch from Vytas Dauksa. 5) Fix netnet and netportnet hash types the range support for IPv4, from Sergey Popovich. 6) Fix missing-field-initializer warnings resolved, from Mark Rustad. 7) Dan Carperter reported possible integer overflows in ipset, from Jozsef Kadlecsick. 8) Filter out accounting objects in nfacct by type, so you can selectively reset quotas, from Alexey Perevalov. 9) Move specific NAT IPv4 functions to the core so x_tables and nf_tables can share the same NAT IPv4 engine. 10) Use the new NAT IPv4 functions from nft_chain_nat_ipv4. 11) Move specific NAT IPv6 functions to the core so x_tables and nf_tables can share the same NAT IPv4 engine. 12) Use the new NAT IPv6 functions from nft_chain_nat_ipv6. 13) Refactor code to add nft_delrule(), which can be reused in the enhancement of the NFT_MSG_DELTABLE to remove a table and its content, from Arturo Borrero. 14) Add a helper function to unregister chain hooks, from Arturo Borrero. 15) A cleanup to rename to nft_delrule_by_chain for consistency with the new nft_*() functions, also from Arturo. 16) Add support to match devgroup to the meta expression, from Ana Rey. 17) Reduce stack usage for IPVS socket option, from Julian Anastasov. 18) Remove unnecessary textsearch state initialization in xt_string, from Bojan Prtvar. 19) Add several helper functions to nf_tables, more work to prepare the enhancement of NFT_MSG_DELTABLE, again from Arturo Borrero. 20) Enhance NFT_MSG_DELTABLE to delete a table and its content, from Arturo Borrero. 21) Support NAT flags in the nat expression to indicate the flavour, eg. random fully, from Arturo. 22) Add missing audit code to ebtables when replacing tables, from Nicolas Dichtel. 23) Generalize the IPv4 masquerading code to allow its re-use from nf_tables, from Arturo. 24) Generalize the IPv6 masquerading code, also from Arturo. 25) Add the new masq expression to support IPv4/IPv6 masquerading from nf_tables, also from Arturo. ==================== Signed-off-by: David S.

2014-09-10libceph: do not hard code max auth ticket lenIlya Dryomov
We hard code cephx auth ticket buffer size to 256 bytes. This isn't enough for any moderate setups and, in case tickets themselves are not encrypted, leads to buffer overflows (ceph_x_decrypt() errors out, but ceph_decode_copy() doesn't - it's just a memcpy() wrapper). Since the buffer is allocated dynamically anyway, allocated it a bit later, at the point where we know how much is going to be needed.

2014-09-09ipv6: Clear flush_id to make GRO workTom Herbert
In TCP gro we check flush_id which is derived from the IP identifier. In IPv4 gro path the flush_id is set with the expectation that every matched packet increments IP identifier. In IPv6, the flush_id is never set and thus is uinitialized. What's worse is that in IPv6 over IPv4 encapsulation, the IP identifier is taken from the outer header which is currently not incremented on every packet for Linux stack, so GRO in this case never matches packets (identifier is not increasing). This patch clears flush_id for every time for a matched packet in IPv6 gro_receive. We need to do this each time to overwrite the setting that would be done in IPv4 gro_receive per the outer header in IPv6 over Ipv4 encapsulation.

struct from userland. Linux manpage for recvmsg and sendmsg calls does not explicitly mention setting msg_namelen to 0 when msg_name passed set as NULL. When developers don't set msg_namelen member in msghdr, it might contain garbage value which will fail the validation check and sendmsg and recvmsg calls from kernel will return EINVAL.

2014-09-09tcp: remove dst refcount false sharing for prequeue modeEric Dumazet
Alexander Duyck reported high false sharing on dst refcount in tcp stack when prequeue is used. prequeue is the mechanism used when a thread is blocked in recvmsg()/read() on a TCP socket, using a blocking model rather than select()/poll()/epoll() non blocking one. We already try to use RCU in input path as much as possible, but we were forced to take a refcount on the dst when skb escaped RCU protected region. When/if the user thread runs on different cpu, dst_release() will then touch dst refcount again. Commit 093162553c33 (tcp: force a dst refcount when prequeue packet) was an example of a race fix. It turns out the only remaining usage of skb->dst for a packet stored in a TCP socket prequeue is IP early demux. We can add a logic to detect when IP early demux is probably going to use skb->dst. Because we do an optimistic check rather than duplicate existing logic, we need to guard inet_sk_rx_dst_set() and inet6_sk_rx_dst_set() from using a NULL dst.
