2013-08-02netlabel: use domain based selectors when address based selectors are not ↵Paul Moore6-158/+130
available NetLabel has the ability to selectively assign network security labels to outbound traffic based on either the LSM's "domain" (different for each LSM), the network destination, or a combination of both. Depending on the type of traffic, local or forwarded, and the type of traffic selector, domain or address based, different hooks are used to label the traffic; the goal being minimal overhead. Unfortunately, there is a bug such that a system using NetLabel domain based traffic selectors does not correctly label outbound local traffic that is not assigned to a socket. The issue is that in these cases the associated NetLabel hook only looks at the address based selectors and not the domain based selectors. This patch corrects this by checking both the domain and address based selectors so that the correct labeling is applied, regardless of the configuration type. In order to acomplish this fix, this patch also simplifies some of the NetLabel domainhash structures to use a more common outbound traffic mapping type: struct netlbl_dommap_def. This simplifies some of the code in this patch and paves the way for further simplifications in the future. Signed-off-by: Paul Moore <pmoore@redhat.com> Signed-off-by: David S.

2013-08-02net: check net.core.somaxconn sysctl valuesRoman Gushchin1-1/+5
It's possible to assign an invalid value to the net.core.somaxconn sysctl variable, because there is no checks at all. The sk_max_ack_backlog field of the sock structure is defined as unsigned short. Therefore, the backlog argument in inet_listen() shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall is truncated to the somaxconn value. So, the somaxconn value shouldn't exceed 65535 (USHRT_MAX). Also, negative values of somaxconn are meaningless. before: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 net.core.somaxconn = 65536 $ sysctl -w net.core.somaxconn=-100 net.core.somaxconn = -100 after: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 error: "Invalid argument" setting key "net.core.somaxconn" $ sysctl -w net.core.somaxconn=-100 error: "Invalid argument" setting key "net.core.somaxconn" Based on a prior patch from Changli Gao.

2013-08-01ipv6: prevent race between address creation and removalJiri Benc1-16/+15
There's a race in IPv6 automatic addess assignment. The address is created with zero lifetime when it's added to various address lists. Before it gets assigned the correct lifetime, there's a window where a new address may be configured. This causes the semi-initiated address to be deleted in addrconf_verify. This was discovered as a reference leak caused by concurrent run of __ipv6_ifa_notify for both RTM_NEWADDR and RTM_DELADDR with the same address. Fix this by setting the lifetime before the address is added to inet6_addr_lst. A few notes: 1. In addrconf_prefix_rcv, by setting update_lft to zero, the if (update_lft) { ... } condition is no longer executed for newly created addresses. This is okay, as the ifp fields are set in ipv6_add_addr now and ipv6_ifa_notify is called (and has been called) through addrconf_dad_start. 2. The removal of the whole block under ifp->lock in inet6_addr_add is okay, too, as tstamp is initialized to jiffies in ipv6_add_addr.

2013-08-01ipv6: prevent fib6_run_gc() contentionMichal Kubeček4-16/+13
On a high-traffic router with many processors and many IPv6 dst entries, soft lockup in fib6_run_gc() can occur when number of entries reaches gc_thresh. This happens because fib6_run_gc() uses fib6_gc_lock to allow only one thread to run the garbage collector but ip6_dst_gc() doesn't update net->ipv6.ip6_rt_last_gc until fib6_run_gc() returns. On a system with many entries, this can take some time so that in the meantime, other threads pass the tests in ip6_dst_gc() (ip6_rt_last_gc is still not updated) and wait for the lock. They then have to run the garbage collector one after another which blocks them for quite long. Resolve this by replacing special value ~0UL of expire parameter to fib6_run_gc() by explicit "force" parameter to choose between spin_lock_bh() and spin_trylock_bh() and call fib6_run_gc() with force=false if gc_thresh is reached but not max_size.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== This pull request is intended for the 3.11 stream. It is a bit larger than usual, as it includes pulls from most of my feeder trees as well... For the Bluetooth bits, Gustavo says: "A few fixes and devices ID additions for 3.11: * There are 4 new ath3k device ids * Fixed stack memory usage in ath3k. * Fixed the init process of BlueFRITZ! devices, they were failing to init due to an unsupported command we sent. * Fixed wrong use of PTR_ERR in btusb code that was preventing intel devices to work properly. * Fixed race condition between hci_register_dev() and hci_dev_open() that could cause a NULL pointer dereference. * Fixed race condition that could call hci_req_cmd_complete() and make some devices to fail as showed in the log added to the commit message." Regarding the NFC bits, Samuel says: "We have: 1) A build failure fix for the NCI SPI transport layer due to a missing CRC_CCITT Kconfig dependency. 2) A netlink command rename: CMD_FW_UPLOAD was merged during the 3.11 merge window but the typical terminology for loading a firmware to a target is firmware download rather than upload. In order to avoid any confusion in a file exported to userspace, we rename this command to CMD_FW_DOWNLOAD." Samuel's item #2 isn't strictly a fix, but it seems safe and should avoid confusion in the future. As for the mac80211 bits, Johannes says: "I only have three fixes this time, a fix for a suspend regression, a patch correcting the initiator in regulatory code and one fix for mesh station powersave." With respect to the iwlwifi bits, Johannes says: "We have a scan fix for passive channels, a new PCI device ID for an old device, a NIC reset fix, an RF-Kill fix, a fix for powersave when GO interfaces are present as well as an aggregation session fix (for a corner case) and a workaround for a firmware design issue - it only supports a single GTK in D3." Bringing-up the rear with the Atheros trees, Kalle says: "Geert Uytterhoeven fixed an ath10k build problem when NO_DMA=y. I added a missing MAINTAINERS entry for ath10k and updated ath6kl git tree location." Along with the above... Arend van Spriel fixes a brcmfmac WARNING when unplugging the device. Avinash Patil proves a couple of minor mwifiex fixes relating to P2P mode. Luciano Coelho updates the MAINTAINERS entry for the wilink drivers. Stanislaw Gruszka brings an rt2x00 fix for a queue start/stop problem. Stone Piao fixes another mwifiex problem, a command timeout related to P2P mode. Tomasz Moń corrects an endian problem in mwifiex. I'll remind my feeder maintainers to slowdown the patchflow.

2013-07-31bridge: disable snooping if there is no querierLinus Lüssing4-11/+46
If there is no querier on a link then we won't get periodic reports and therefore won't be able to learn about multicast listeners behind ports, potentially leading to lost multicast packets, especially for multicast listeners that joined before the creation of the bridge. These lost multicast packets can appear since c5c23260594 ("bridge: Add multicast_querier toggle and disable queries by default") in particular. With this patch we are flooding multicast packets if our querier is disabled and if we didn't detect any other querier. A grace period of the Maximum Response Delay of the querier is added to give multicast responses enough time to arrive and to be learned from before disabling the flooding behaviour again.

2013-07-318139cp: Add dma_mapping_error checkingNeil Horman1-3/+45
Self explanitory dma_mapping_error addition to the 8139 driver, based on this: https://bugzilla.redhat.com/show_bug.cgi?id=947250 It showed several backtraces arising for dma_map_* usage without checking the return code on the mapping. Add the check and abort the rx/tx operation if its failed. Untested as I have no hardware and the reporter has wandered off, but seems pretty straightforward.

2013-07-30genetlink: fix usage of NLM_F_EXCL or NLM_F_REPLACEPablo Neira1-1/+1
Currently, it is not possible to use neither NLM_F_EXCL nor NLM_F_REPLACE from genetlink. This is due to this checking in genl_family_rcv_msg: if (nlh->nlmsg_flags & NLM_F_DUMP) NLM_F_DUMP is NLM_F_MATCH|NLM_F_ROOT. Thus, if NLM_F_EXCL or NLM_F_REPLACE flag is set, genetlink believes that you're requesting a dump and it calls the .dumpit callback. The solution that I propose is to refine this checking to make it stricter: if ((nlh->nlmsg_flags & NLM_F_DUMP) == NLM_F_DUMP) And given the combination NLM_F_REPLACE and NLM_F_EXCL does not make sense to me, it removes the ambiguity. There was a patch that tried to fix this some time ago (0ab03c2 netlink: test for all flags of the NLM_F_DUMP composite) but it tried to resolve this ambiguity in *all* existing netlink subsystems, not only genetlink. That patch was reverted since it broke iproute2, which is using NLM_F_ROOT to request the dump of the routing cache. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.

Don't test for having link and let hardware deal with this situation. Without this patch I see a machine running an -rt patched Linux being stuck in sch_direct_xmit when it looses link while there is still a packet to be sent. In this case the fec_enet_start_xmit routine returned NETDEV_TX_BUSY which makes the network stack reschedule the packet and so sch_direct_xmit calls fec_enet_start_xmit again. I failed to reproduce a complete hang without -rt, but I think the problem exists there, too. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: David S.
