Conflicts: net/netfilter/nfnetlink_log.c net/netfilter/xt_LOG.c Rather easy conflict resolution, the 'net' tree had bug fixes to make sure we checked if a socket is a time-wait one or not and elide the logging code if so. Whereas on the 'net-next' side we are calculating the UID and GID from the creds using different interfaces due to the user namespace changes from Eric Biederman. Signed-off-by: David S.

2012-09-10netlink: Rename pid to portid to avoid confusionEric W. Biederman
It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by: "Eric W.

2012-09-07scm: Don't use struct ucred in NETLINK_CB and struct scm_cookie.Eric W. Biederman
Passing uids and gids on NETLINK_CB from a process in one user namespace to a process in another user namespace can result in the wrong uid or gid being presented to userspace. Avoid that problem by passing kuids and kgids instead. - define struct scm_creds for use in scm_cookie and netlink_skb_parms that holds uid and gid information in kuid_t and kgid_t. - Modify scm_set_cred to fill out scm_creds by heand instead of using cred_to_ucred to fill out struct ucred. This conversion ensures userspace does not get incorrect uid or gid values to look at. - Modify scm_recv to convert from struct scm_creds to struct ucred before copying credential values to userspace. - Modify __scm_send to populate struct scm_creds on in the scm_cookie, instead of just copying struct ucred from userspace. - Modify netlink_sendmsg to copy scm_creds instead of struct ucred into the NETLINK_CB.

There are more commits here than I would like -- I got a bit behind while I was stalking Steven Rostedt in San Diego last week... I'll slow it down after this! There are a couple of pulls here. One is from Johannes: "Please pull (according to the below information) to get a few fixes. * a fix to properly disconnect in the driver when authentication or association fails * a fix to prevent invalid information about mesh paths being reported to userspace * a memory leak fix in an nl80211 error path" The other comes via Gustavo: "A few updates for the 3.6 kernel. There are two btusb patches to add more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO() macro and another one that add a new device id for a Sony Vaio laptop, one fix for a user-after-free and, finally, two patches from Vinicius to fix a issue in SMP pairing." Along with those... Arend van Spriel provides a fix for a use-after-free bug in brcmfmac. Daniel Drake avoids a hang by not trying to touch the libertas hardware duing suspend if it is already powered-down. Felix Fietkau provides a batch of ath9k fixes that adress some potential problems with power settings, as well as a fix to avoid a potential interrupt storm. Gertjan van Wingerde provides a register-width fix for rt2x00, and a rt2x00 fix to prevent incorrectly detecting the rfkill status. He also provides a device ID patch. Hante Meuleman gives us three brcmfmac fixes, one that properly initializes a command structure, one that fixes a race condition that could lose usb requests, and one that removes some log spam. Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some specific devices. Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to using timers that aren't allocated when 2 wire bluetooth coexistence hardware is in use. Sergei Poselenov changes rt2800usb to do some validity checking for received packets, avoiding crashes on an ARM Soc. Stone Piao gives us an mwifiex fix for an incorrectly set skb length value for a command buffer. All of these are localized to their specific drivers, and relatively small. The power-related patches from Felix are bigger than I would like, but I merged them in consideration of their isolation to ath9k and the sensitive nature of power settings in wireless devices. ==================== Signed-off-by: David S.

2012-09-04xfrm: Workaround incompatibility of ESN and async cryptoSteffen Klassert
ESN for esp is defined in RFC 4303. This RFC assumes that the sequence number counters are always up to date. However, this is not true if an async crypto algorithm is employed. If the sequence number counters are not up to date on sequence number check, we may incorrectly update the upper 32 bit of the sequence number. This leads to a DOS. We workaround this by comparing the upper sequence number, (used for authentication) with the upper sequence number computed after the async processing. We drop the packet if these numbers are different. To do this, we introduce a recheck function that does this check in the ESN case.

2012-09-03tcp: use PRR to reduce cwin in CWR stateYuchung Cheng
Use proportional rate reduction (PRR) algorithm to reduce cwnd in CWR state, in addition to Recovery state. Retire the current rate-halving in CWR. When losses are detected via ACKs in CWR state, the sender enters Recovery state but the cwnd reduction continues and does not restart. Rename and refactor cwnd reduction functions since both CWR and Recovery use the same algorithm: tcp_init_cwnd_reduction() is new and initiates reduction state variables. tcp_cwnd_reduction() is previously tcp_update_cwnd_in_recovery(). tcp_ends_cwnd_reduction() is previously tcp_complete_cwr(). The rate halving functions and logic such as tcp_cwnd_down(), tcp_min_cwnd(), and the cwnd moderation inside tcp_enter_cwr() are removed. The unused parameter, flag, in tcp_cwnd_reduction() is also removed. Signed-off-by: Yuchung Cheng <ycheng@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

2012-08-31tcp: TCP Fast Open Server - support TFO listenersJerry Chu
This patch builds on top of the previous patch to add the support for TFO listeners. This includes - 1. allocating, properly initializing, and managing the per listener fastopen_queue structure when TFO is enabled 2. changes to the inet_csk_accept code to support TFO. E.g., the request_sock can no longer be freed upon accept(), not until 3WHS finishes 3. allowing a TCP_SYN_RECV socket to properly poll() and sendmsg() if it's a TFO socket 4. properly closing a TFO listener, and a TFO socket before 3WHS finishes 5. supporting TCP_FASTOPEN socket option 6. modifying tcp_check_req() to use to check a TFO socket as well as request_sock 7. supporting TCP's TFO cookie option 8. adding a new SYN-ACK retransmit handler to use the timer directly off the TFO socket rather than the listener socket. Note that TFO server side will not retransmit anything other than SYN-ACK until the 3WHS is completed. The patch also contains an important function "reqsk_fastopen_remove()" to manage the somewhat complex relation between a listener, its request_sock, and the corresponding child socket. See the comment above the function for the detail. Signed-off-by: H.K.

2012-08-31tcp: TCP Fast Open Server - header & support functionsJerry Chu
This patch adds all the necessary data structure and support functions to implement TFO server side. It also documents a number of flags for the sysctl_tcp_fastopen knob, and adds a few Linux extension MIBs. In addition, it includes the following: 1. a new TCP_FASTOPEN socket option an application must call to supply a max backlog allowed in order to enable TFO on its listener. 2. A number of key data structures: "fastopen_rsk" in tcp_sock - for a big socket to access its request_sock for retransmission and ack processing purpose. It is non-NULL iff 3WHS not completed. "fastopenq" in request_sock_queue - points to a per Fast Open listener data structure "fastopen_queue" to keep track of qlen (# of outstanding Fast Open requests) and max_qlen, among other things. "listener" in tcp_request_sock - to point to the original listener for book-keeping purpose, i.e., to maintain qlen against max_qlen as part of defense against IP spoofing attack. 3. various data structure and functions, many in tcp_fastopen.c, to support server side Fast Open cookie operations, including /proc/sys/net/ipv4/tcp_fastopen_key to allow manual rekeying.

2012-08-31tcp: Increase timeout for SYN segmentsAlex Bergmann
Commit 9ad7c049 ("tcp: RFC2988bis + taking RTT sample from 3WHS for the passive open side") changed the initRTO from 3secs to 1sec in accordance to RFC6298 (former RFC2988bis). This reduced the time till the last SYN retransmission packet gets sent from 93secs to 31secs. RFC1122 is stating that the retransmission should be done for at least 3 minutes, but this seems to be quite high. "However, the values of R1 and R2 may be different for SYN and data segments. In particular, R2 for a SYN segment MUST be set large enough to provide retransmission of the segment for at least 3 minutes. The application can close the connection (i.e., give up on the open attempt) sooner, of course." This patch increases the value of TCP_SYN_RETRIES to the value of 6, providing a retransmission window of 63secs. The comments for SYN and SYNACK retries have also been updated to describe the current settings. The same goes for the documentation file "Documentation/networking/ip-sysctl.txt".

2012-08-31netfilter: nf_conntrack: fix racy timer handling with reliable eventsPablo Neira Ayuso
Existing code assumes that del_timer returns true for alive conntrack entries. However, this is not true if reliable events are enabled. In that case, del_timer may return true for entries that were just inserted in the dying list. Note that packets / ctnetlink may hold references to conntrack entries that were just inserted to such list. This patch fixes the issue by adding an independent timer for event delivery. This increases the size of the ecache extension. Still we can revisit this later and use variable size extensions to allocate this area on demand.

2012-08-26ipv4: fix path MTU discovery with connection trackingPatrick McHardy
IPv4 conntrack defragments incoming packet at the PRE_ROUTING hook and (in case of forwarded packets) refragments them at POST_ROUTING independent of the IP_DF flag. Refragmentation uses the dst_mtu() of the local route without caring about the original fragment sizes, thereby breaking PMTUD. This patch fixes this by keeping track of the largest received fragment with IP_DF set and generates an ICMP fragmentation required error during refragmentation if that size exceeds the MTU.

This lock currently protects two modifications: * sklist * prot inuse counters The sklist modifications can be just reprotected with mutex since they already occur in a sleeping context. The inuse counters modifications are trickier -- the __this_cpu_-s are used inside, thus requiring the caller to handle the potential issues with contexts himself. Since packet sockets' counters are modified in two places only (packet_create and packet_release) we only need to protect the context from being preempted. BH disabling is not required in this case.

2012-08-21af_netlink: force credentials passing [CVE-2012-3520]Eric Dumazet
Pablo Neira Ayuso discovered that avahi and potentially NetworkManager accept spoofed Netlink messages because of a kernel bug. The kernel passes all-zero SCM_CREDENTIALS ancillary data to the receiver if the sender did not provide such data, instead of not including any such data at all or including the correct data from the peer (as it is the case with AF_UNIX). This bug was introduced in commit 16e572626961 (af_unix: dont send SCM_CREDENTIALS by default) This patch forces passing credentials for netlink, as before the regression. Another fix would be to not add SCM_CREDENTIALS in netlink messages if not provided by the sender, but it might break some programs.

This abstraction will also be useful to support offloading P2P operations to the device, e.g. periodic listen for discoverability. Currently, the driver is responsible for assigning a MAC address to the P2P Device, but this could be changed by allowing a MAC address to be given to the NEW_INTERFACE command. As it has no associated netdev, a P2P Device can only be identified by its wdev identifier but the previous patches allowed using the wdev identifier in various APIs, e.g. remain-on-channel.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== This is a batch of updates intended for 3.7. The ath9k, mwifiex, and b43 drivers get the bulk of the commits this time, with a handful of other driver bits thrown-in. It is mostly just minor fixes and cleanups, etc. Also included is a Bluetooth pull, with a lot of refactoring. Gustavo says: "These are the changes I queued for 3.7. There are a many small fixes/improvements by Andre Guedes. A l2cap channel refcounting refactor by Jaganath. Bluetooth sockets now appears in /proc/net, by Masatake Yamato and Sachin Kamat changes ours drivers to use devm_kzalloc()." ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2012-08-15xfrm: remove redundant parameter "int dir" in struct xfrm_mgr.acquireFan Du
Sematically speaking, xfrm_mgr.acquire is called when kernel intends to ask user space IKE daemon to negotiate SAs with peers. IOW the direction will *always* be XFRM_POLICY_OUT, so remove int dir for clarity. Signed-off-by: Fan Du <fan.du@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-08-14sctp: Push struct net down into sctp_verify_ext_paramEric W. Biederman
Add struct net as a parameter to sctp_verify_param so it can be passed to sctp_verify_ext_param where struct net will be needed when the sctp tunables become per net tunables.

2012-08-14sctp: Push struct net down into all of the state machine functionsEric W. Biederman
There are a handle of state machine functions primarily those dealing with processing INIT packets where there is neither a valid endpoint nor a valid assoication from which to derive a struct net. Therefore add struct net * to the parameter list of sctp_state_fn_t and update all of the state machine functions. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S.
