2012-04-25ipvs: fix crash in ip_vs_control_net_cleanup on unloadJulian Anastasov
commit 14e405461e664b777e2a5636e10b2ebf36a686ec (2.6.39) ("Add __ip_vs_control_{init,cleanup}_sysctl()") introduced regression due to wrong __net_init for __ip_vs_control_cleanup_sysctl. This leads to crash when the ip_vs module is unloaded. Fix it by changing __net_init to __net_exit for the function that is already renamed to ip_vs_control_net_cleanup_sysctl.

2012-04-10netfilter: nf_ct_ipv4: packets with wrong ihl are invalidJozsef Kadlecsik
It was reported that the Linux kernel sometimes logs: klogd: [2629147.402413] kernel BUG at net / netfilter / nf_conntrack_proto_tcp.c: 447! klogd: [1072212.887368] kernel BUG at net / netfilter / nf_conntrack_proto_tcp.c: 392 ipv4_get_l4proto() in nf_conntrack_l3proto_ipv4.c and tcp_error() in nf_conntrack_proto_tcp.c should catch malformed packets, so the errors at the indicated lines - TCP options parsing - should not happen. However, tcp_error() relies on the "dataoff" offset to the TCP header, calculated by ipv4_get_l4proto(). But ipv4_get_l4proto() does not check bogus ihl values in IPv4 packets, which then can slip through tcp_error() and get caught at the TCP options parsing routines. The patch fixes ipv4_get_l4proto() by invalidating packets with bogus ihl value. The patch closes netfilter bugzilla id 771.

A phonet packet is limited to USHRT_MAX bytes, this is never checked during tx which means that the user can specify any size he wishes, and the kernel will attempt to allocate that size.

2012-04-05tcp: tcp_sendpages() should call tcp_push() onceEric Dumazet
commit 2f533844242 (tcp: allow splice() to build full TSO packets) added a regression for splice() calls using SPLICE_F_MORE. We need to call tcp_flush() at the end of the last page processed in tcp_sendpages(), or else transmits can be deferred and future sends stall. Add a new internal flag, MSG_SENDPAGE_NOTLAST, acting like MSG_MORE, but with different semantic. For all sendpage() providers, its a transparent change. Only sock_sendpage() and tcp_sendpages() can differentiate the two different flags provided by pipe_to_sendpage() Reported-by: Tom Herbert <therbert@google.com> Cc: Nandita Dukkipati <nanditad@google.com> Cc: Neal Cardwell <ncardwell@google.com> Cc: Tom Herbert <therbert@google.com> Cc: Yuchung Cheng <ycheng@google.com> Cc: H.K.

2012-04-04mlx4: allocate just enough pages instead of always 4 pagesThadeu Lima de Souza Cascardo
The driver uses a 2-order allocation, which is too much on architectures like ppc64, which has a 64KiB page. This particular allocation is used for large packet fragments that may have a size of 512, 1024, 4096 or fill the whole allocation. So, a minimum size of 16384 is good enough and will be the same size that is used in architectures of 4KiB sized pages. This will avoid allocation failures that we see when the system is under stress, but still has plenty of memory, like the one below. This will also allow us to set the interface MTU to higher values like 9000, which was not possible on ppc64 without this patch.

This patch fixes a link problem on BCM57712 + BCM8727 designs in which the TX laser is controller by GPIO, after 1.60.xx drivers were previously loaded. On these designs the TX_LASER is enabled by logic AND between the PHY (through MDIO), and the GPIO. When an old driver is used, it disables the MDIO part, hence the GPIO control had no affect de facto.

2012-04-04sky2: copy received packets on inefficient unaligned architecturestephen hemminger
Modified from original patch from Chris. The sky2 driver has to have 8 byte alignment of receive buffer on some chip versions. On architectures which don't support efficient unaligned access this doesn't work very well. The solution is to just copy all received packets which is what the driver already does for small packets. This allows the driver to be used on the Tilera TILEmpower-Gx, since the tile architecture doesn't currently handle kernel unaligned accesses, just userspace.

2012-04-04net/bonding: correctly proxy slave neigh param setup ndo functionShlomo Pongratz
The current implemenation was buggy for slaves who use ndo_neigh_setup, since the networking stack invokes the bonding device ndo entry (from neigh_params_alloc) before any devices are enslaved, and the bonding driver can't further delegate the call at that point in time. As a result when bonding IPoIB devices, the neigh_cleanup hasn't been called. Fix that by deferring the actual call into the slave ndo_neigh_setup from the time the bonding neigh_setup is called.

2012-04-04sctp: Allow struct sctp_event_subscribe to grow without breaking binariesThomas Graf
getsockopt(..., SCTP_EVENTS, ...) performs a length check and returns an error if the user provides less bytes than the size of struct sctp_event_subscribe. Struct sctp_event_subscribe needs to be extended by an u8 for every new event or notification type that is added. This obviously makes getsockopt fail for binaries that are compiled against an older versions of <net/sctp/user.h> which do not contain all event types. This patch changes getsockopt behaviour to no longer return an error if not enough bytes are being provided by the user. Instead, it returns as much of sctp_event_subscribe as fits into the provided buffer. This leads to the new behavior that users see what they have been aware of at compile time. The setsockopt(..., SCTP_EVENTS, ...) API is already behaving like this. Signed-off-by: Thomas Graf <tgraf@suug.ch> Acked-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.
