2014-07-11net/hsr: Remove left-over never-true conditional code.Arvid Brodin
MacAddressB is an array (unsigned char MacAddressB[ETH_ALEN]) and is allocated as a part of *node_dst (which is a struct hsr_node). So the condition is always false. Detected by Dan Carpenter. Signed-off-by: Arvid Brodin <arvid.brodin@alten.se> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-11tipc: clear 'next'-pointer of message fragments before reassemblyJon Paul Maloy
If the 'next' pointer of the last fragment buffer in a message is not zeroed before reassembly, we risk ending up with a corrupt message, since the reassembly function itself isn't doing this. Currently, when a buffer is retrieved from the deferred queue of the broadcast link, the next pointer is not cleared, with the result as described above. This commit corrects this, and thereby fixes a bug that may occur when long broadcast messages are transmitted across dual interfaces. The bug has been present since 40ba3cdf542a469aaa9083fa041656e59b109b90 ("tipc: message reassembly using fragment chain") This commit should be applied to both net and net-next.

2014-07-11Bluetooth: Fix tracking local SSP authentication requirementJohan Hedberg
When we need to make the decision whether to perform just-works or real user confirmation we need to know the exact local authentication requirement that was passed to the controller. So far conn->auth_type (the local requirement) wasn't in one case updated appropriately in fear of the user confirmation being rejected later. The real problem however was not really that conn->auth_type couldn't represent the true value but that we were checking the local MITM requirement in an incorrect way. It's perfectly fine to let auth_type follow what we tell the controller since we're still tracking the target security level with conn->pending_sec_level. This patch updates the check for local MITM requirement in the hci_user_confirm_request_evt function to use the locally requested security level and ensures that auth_type always represents what we tell the controller. All other code in hci_user_confirm_request_evt still uses the auth_type instead of pending_sec_level for determining whether to do just-works or not, since that's the only value that's in sync with what the remote device knows.

2014-07-10tty: Remove tty_hung_up_p() tests from tty drivers' open()Peter Hurley
Since at least before 2.6.30, it has not been possible to observe a hung up file pointer in a tty driver's open() method unless/until the driver open() releases the tty_lock() (eg., before blocking). This is because tty_open() adds the file pointer while holding the tty_lock() _and_ doesn't release the lock until after calling the tty driver's open() method. [ Before tty_lock(), this was lock_kernel(). ] Since __tty_hangup() first waits on the tty_lock() before enumerating and hanging up the open file pointers, either __tty_hangup() will wait for the tty_lock() or tty_open() will not yet have added the file pointer. For example, CPU 0 | CPU 1 | tty_open | __tty_hangup .. | .. tty_lock | .. tty_reopen | tty_lock / blocks .. | tty_add_file(tty, filp) | .. | tty->ops->open(tty, filp) | tty_port_open | tty_port_block_til_ready | .. | while (1) | .. | tty_unlock | / unblocks schedule | for each filp on tty->tty_files | f_ops = tty_hung_up_fops; | .. | tty_unlock tty_lock | .. | tty_unlock | Note that since tty_port_block_til_ready() and similar drop the tty_lock while blocking, when woken, the file pointer must then be tested for having been hung up. Also, fix bit-rotted drivers that used extra_count to track the port->count bump. CC: Mikael Starvik <starvik@axis.com> CC: Samuel Ortiz <samuel@sortiz.org> CC: "David S.

2014-07-09netlink: Fix handling of error from netlink_dump().Ben Pfaff
netlink_dump() returns a negative errno value on error. Until now, netlink_recvmsg() directly recorded that negative value in sk->sk_err, but that's wrong since sk_err takes positive errno values. (This manifests as userspace receiving a positive return value from the recv() system call, falsely indicating success.) This bug was introduced in the commit that started checking the netlink_dump() return value, commit b44d211 (netlink: handle errors from netlink_dump()). Multithreaded Netlink dumps are one way to trigger this behavior in practice, as described in the commit message for the userspace workaround posted here: http://openvswitch.org/pipermail/dev/2014-June/042339.html This commit also fixes the same bug in netlink_poll(), introduced in commit cd1df525d (netlink: add flow control for memory mapped I/O).

When the SMP context is created all flags default to zero. To determine that we are the initiators it's therefore best to simply change the flag value when we know we're sending the first SMP PDU.

After a bonding master reclaims the netpoll info struct, slaves could still hold a pointer to the reclaimed data. This patch fixes it: as soon as netpoll_async_cleanup is called for a slave (eg. when un-enslaved), we make sure that this slave doesn't point to the data.

2014-07-08appletalk: Fix socket referencing in skbAndrey Utkin
Setting just skb->sk without taking its reference and setting a destructor is invalid. However, in the places where this was done, skb is used in a way not requiring skb->sk setting. So dropping the setting of skb->sk. Thanks to Eric Dumazet <eric.dumazet@gmail.com> for correct solution.

2014-07-08ip_tunnel: fix ip_tunnel_lookupDmitry Popov
This patch fixes 3 similar bugs where incoming packets might be routed into wrong non-wildcard tunnels: 1) Consider the following setup: ip address add 1.1.1.1/24 dev eth0 ip address add 1.1.1.2/24 dev eth0 ip tunnel add ipip1 remote 2.2.2.2 local 1.1.1.1 mode ipip dev eth0 ip link set ipip1 up Incoming ipip packets from 2.2.2.2 were routed into ipip1 even if it has dst = 1.1.1.2. Moreover even if there was wildcard tunnel like ip tunnel add ipip0 remote 2.2.2.2 local any mode ipip dev eth0 but it was created before explicit one (with local 1.1.1.1), incoming ipip packets with src = 2.2.2.2 and dst = 1.1.1.2 were still routed into ipip1. Same issue existed with all tunnels that use ip_tunnel_lookup (gre, vti) 2) ip address add 1.1.1.1/24 dev eth0 ip tunnel add ipip1 remote 2.2.146.85 local 1.1.1.1 mode ipip dev eth0 ip link set ipip1 up Incoming ipip packets with dst = 1.1.1.1 were routed into ipip1, no matter what src address is. Any remote ip address which has ip_tunnel_hash = 0 raised this issue, 2.2.146.85 is just an example, there are more than 4 million of them. And again, wildcard tunnel like ip tunnel add ipip0 remote any local 1.1.1.1 mode ipip dev eth0 wouldn't be ever matched if it was created before explicit tunnel like above. Gre & vti tunnels had the same issue. 3) ip address add 1.1.1.1/24 dev eth0 ip tunnel add gre1 remote 2.2.146.84 local 1.1.1.1 key 1 mode gre dev eth0 ip link set gre1 up Any incoming gre packet with key = 1 were routed into gre1, no matter what src/dst addresses are. Any remote ip address which has ip_tunnel_hash = 0 raised the issue, 2.2.146.84 is just an example, there are more than 4 million of them. Wildcard tunnel like ip tunnel add gre2 remote any local any key 1 mode gre dev eth0 wouldn't be ever matched if it was created before explicit tunnel like above. All this stuff happened because while looking for a wildcard tunnel we didn't check that matched tunnel is a wildcard one. Fixed.

2014-07-08bridge: export knowledge about the presence of IGMP/MLD queriersLinus Lüssing
With this patch other modules are able to ask the bridge whether an IGMP or MLD querier exists on the according, bridged link layer. Multicast snooping can only be performed if a valid, selected querier exists on a link. Just like the bridge only enables its multicast snooping if a querier exists, e.g. batman-adv too can only activate its multicast snooping in bridged scenarios if a querier is present. For instance this export avoids having to reimplement IGMP/MLD querier message snooping and parsing in e.g. batman-adv, when multicast optimizations for bridged scenarios are added in the future.
