* net: pass kern to net_proto_family create functionEric Paris2009-11-0634-40/+75
| | | | | | | | | | | The generic __sock_create function has a kern argument which allows the security system to make decisions based on if a socket is being created by the kernel or by userspace. This patch passes that flag to the net_proto_family specific create function, so it can do the same thing.

| | | | | | | | | | | | | | | | | | Calling IPv4 specific inet_csk_route_req in tcp_check_req is a bad idea and crashes machine on IPv6 connections, as reported by Valdis Kletnieks Also, all we are really interested in is the timestamp option in the header, so calling tcp_parse_options() with the "estab" set to false flag is an overkill as it tries to parse half a dozen other TCP options.

| | | | | | | | | | | | | | | | | | | | | | "At rds_ib_recv_refill_one(), it first executes atomic_read(&rds_ib_allocation) for if-condition checking, and then executes atomic_inc(&rds_ib_allocation) if the condition was not satisfied. However, if any other code which updates rds_ib_allocation executes between these two atomic operation executions, it seems that it may result race condition. (especially when rds_ib_allocation + 1 == rds_ib_sysctl_max_recv_allocation)" This patch fixes this by using atomic_inc_unless to eliminate the possibility of allocating more than rds_ib_sysctl_max_recv_allocation and then decrementing the count if the allocation fails.

* RDS: Add GET_MR_FOR_DEST sockoptAndy Grover2009-10-303-0/+28
| | | | | | | | | | | | | | | | RDS currently supports a GET_MR sockopt to establish a memory region (MR) for a chunk of memory. However, the fastreg method ties a MR to a particular destination. The GET_MR_FOR_DEST sockopt allows the remote machine to be specified, and thus support for fastreg (aka FRWRs). Note that this patch does *not* do all of this - it simply implements the new sockopt in terms of the old one, so applications can begin to use the new sockopt in preparation for cutover to FRWRs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently PACKET_TX_RING forces certain amount of every frame to remain unused. This probably originates from an early version of the PACKET_TX_RING patch that in fact used the extra space when the (since removed) CONFIG_PACKET_MMAP_ZERO_COPY option was enabled.

| * AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl (v2)Neil Horman2009-10-291-7/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Augment raw_send_hdrinc to correct for incorrect ip header length values A series of oopses was reported to me recently. Apparently when using AF_RAW sockets to send data to peers that were reachable via ipsec encapsulation, people could panic or BUG halt their systems. I've tracked the problem down to user space sending an invalid ip header over an AF_RAW socket with IP_HDRINCL set to 1. Basically what happens is that userspace sends down an ip frame that includes only the header (no data), but sets the ip header ihl value to a large number, one that is larger than the total amount of data passed to the sendmsg call. In raw_send_hdrincl, we allocate an skb based on the size of the data in the msghdr that was passed in, but assume the data is all valid. Later during ipsec encapsulation, xfrm4_tranport_output moves the entire frame back in the skbuff to provide headroom for the ipsec headers. During this operation, the skb->transport_header is repointed to a spot computed by skb->network_header + the ip header length (ihl). Since so little data was passed in relative to the value of ihl provided by the raw socket, we point transport header to an unknown location, resulting in various crashes. This fix for this is pretty straightforward, simply validate the value of of iph->ihl when sending over a raw socket. If (iph->ihl*4U) > user data buffer size, drop the frame and return -EINVAL. I just confirmed this fixes the reported crashes. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

| * mac80211: fix for incorrect sequence number on hostapd injected framesBjörn Smedman2009-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When hostapd injects a frame, e.g. an authentication or association response, mac80211 looks for a suitable access point virtual interface to associate the frame with based on its source address. This makes it possible e.g. to correctly assign sequence numbers to the frames. A small typo in the ethernet address comparison statement caused a failure to find a suitable ap interface. Sequence numbers on such frames where therefore left unassigned causing some clients (especially windows-based 11b/g clients) to reject them and fail to authenticate or associate with the access point. This patch fixes the typo in the address comparison statement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent commit "mac80211: fix logic error ibss merge bssid check" fixed joining of ibss cell when static bssid is provided. In this case ifibss->bssid is set before the cell is joined and comparing that address to a bss should thus always succeed. Unfortunately this change broke the other case of joining a ibss cell without providing a static bssid where the value of ifibss->bssid is not set before the cell is joined. Since ifibss->bssid may be set before or after joining the cell we do not learn anything by comparing it to a known bss. Remove this check.
