| * | atl1: reduce forward declarationsJay Cliburn2008-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | Rearrange functions to allow removal of some forward declarations. Make certain global functions static along the way.

| * | atl1: simplify tx packet descriptorJay Cliburn2008-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The transmit packet descriptor consists of four 32-bit words, with word 3 upper bits overloaded depending upon the condition of its bits 3 and 4. The driver currently duplicates all word 2 and some word 3 register bit definitions unnecessarily and also uses a set of nested structures in its definition of the TPD without good cause. This patch adds a lengthy comment describing the TPD, eliminates duplicate TPD bit definitions, and simplifies the TPD structure itself. It also expands the TSO check to correctly handle custom checksum versus TSO processing using the revised TPD definitions. Finally, shorten some variable names in the transmit processing path to reduce line lengths, rename some variables to better describe their purpose (e.g., nseg versus m), and add a comment or two to better describe what the code is doing.

| * | atl1: fix broken TSOJay Cliburn2008-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The L1 tx packet descriptor expects TCP Header Length to be expressed as a number of 32-bit dwords. The atl1 driver uses tcp_hdrlen() to populate the field, but tcp_hdrlen() returns the header length in bytes, not in dwords. Add a shift to convert tcp_hdrlen() to dwords when we write it to the tpd. Also, some of our bit assignments are made to the wrong tpd words. Change those to the correct words. Finally, since all this fixes TSO, enable TSO by default.

| * | atl1: move common functions to atlx filesJay Cliburn2008-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The future atl2 driver and the existing atl1 driver can share certain functions and definitions. Move these shareable functions and definitions out of atl1-specific files and into atlx.c and atlx.h. Some transitory hackery will be present until atl2 is merged. Reduce the number of source files by moving ethtool, hw, and param functions from separate files into atl1_main.c, then rename it to just atl1.c. Move all atl1-specific definitions from atl1_hw.h to atl1.h. Finally, clean up to make checkpatch.pl happy.

* | | [SOCK]: Add udp_hash member to struct proto.Pavel Emelyanov2008-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inspired by the commit ab1e0a13 ([SOCK] proto: Add hashinfo member to struct proto) from Arnaldo, I made similar thing for UDP/-Lite IPv4 and -v6 protocols. The result is not that exciting, but it removes some levels of indirection in udpxxx_get_port and saves some space in code and text. The first step is to union existing hashinfo and new udp_hash on the struct proto and give a name to this union, since future initialization of tcpxxx_prot, dccp_vx_protinfo and udpxxx_protinfo will cause gcc warning about inability to initialize anonymous member this way.

I.e. when checking for socket to belong to given net and family the do { sk = sk_next(sk); } while (sk && sk->sk_net != net && sk->sk_family != family); constructions were used. This is wrong, since as soon as the sk->sk_net fits the net the socket is immediately returned, even if it belongs to other family. As the result four /proc/net/(udp|tcp)[6] entries show wrong info. The udp6 entry even oopses when dereferencing inet6_sk(sk) pointer: static void udp6_sock_seq_show(struct seq_file *seq, struct sock *sp, int bucket) { ... struct ipv6_pinfo *np = inet6_sk(sp); ... dest = &np->daddr; /* will be NULL for AF_INET sockets */ ... seq_printf(... dest->s6_addr32[0], dest->s6_addr32[1], dest->s6_addr32[2], dest->s6_addr32[3], ...

Fixed the parameter in netif_set_gso_max_size() to be u32, not u16. Fixed the whitespace issue due to a patch import botch. Changed the types from u32 to unsigned int to be more consistent with other variables in the area. Also brought the patch up to the latest net-2.6.26 tree. Update: Made gso_max_size container 32 bits, not 16. Moved the location of gso_max_size within netdev to be less hotpath. Made more consistent names between the sock and netdev layers, and added a define for the max GSO size. Update: Respun for net-2.6.26 tree. Update: changed max_gso_frame_size and sk_gso_max_size from signed to unsigned - thanks Stephen! This patch adds the ability for device drivers to control the size of the TSO frames being sent to them, per TCP connection. By setting the netdevice's gso_max_size value, the socket layer will set the GSO frame size based on that value. This will propogate into the TCP layer, and send TSO's of that size to the hardware. This can be desirable to help tune the bursty nature of TSO on a per-adapter basis, where one may have 1 GbE and 10 GbE devices coexisting in a system, one running multiqueue and the other not, etc. This can also be desirable for devices that cannot support full 64 KB TSO's, but still want to benefit from some level of segmentation offloading.

The newly calculated window size is always a multiple of the window scaling factor, the remaining window size however might not be since it depends on rcv_wup/rcv_nxt. This means we're effectively shrinking the window when scaling it down. The dump below shows the problem (scaling factor 2^7): - Window size of 557 (71296) is advertised, up to 3111907257: IP 172.2.2.3.33000 > 172.2.2.2.33000: . ack 3111835961 win 557 <...> - New window size of 514 (65792) is advertised, up to 3111907217, 40 bytes below the last end: IP 172.2.2.3.33000 > 172.2.2.2.33000: . 3113575668:3113577116(1448) ack 3111841425 win 514 <...> The number 40 results from downscaling the remaining window: 3111907257 - 3111841425 = 65832 65832 / 2^7 = 514 65832 % 2^7 = 40 If the sender uses up the entire window before it is shrunk, this can have chaotic effects on the connection. When sending ACKs, tcp_acceptable_seq() will notice that the window has been shrunk since tcp_wnd_end() is before tp->snd_nxt, which makes it choose tcp_wnd_end() as sequence number. This will fail the receivers checks in tcp_sequence() however since it is before it's tp->rcv_wup, making it respond with a dupack. If both sides are in this condition, this leads to a constant flood of ACKs until the connection times out. Make sure the window is never shrunk by aligning the remaining window to the window scaling factor. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| * | audit: netlink socket can be auto-bound to pid other than current->pid (v2)Pavel Emelyanov2008-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Pavel Emelyanov <xemul@openvz.org> This patch is based on the one from Thomas. The kauditd_thread() calls the netlink_unicast() and passes the audit_pid to it. The audit_pid, in turn, is received from the user space and the tool (I've checked the audit v1.6.9) uses getpid() to pass one in the kernel. Besides, this tool doesn't bind the netlink socket to this id, but simply creates it allowing the kernel to auto-bind one. That's the preamble. The problem is that netlink_autobind() _does_not_ guarantees that the socket will be auto-bound to the current pid. Instead it uses the current pid as a hint to start looking for a free id. So, in case of conflict, the audit messages can be sent to a wrong socket. This can happen (it's unlikely, but can be) in case some task opens more than one netlink sockets and then the audit one starts - in this case the audit's pid can be busy and its socket will be bound to another id. The proposal is to introduce an audit_nlk_pid in audit subsys, that will point to the netlink socket to send packets to. It will most often be equal to audit_pid. The socket id can be got from the skb's netlink CB right in the audit_receive_msg. The audit_nlk_pid reset to 0 is not required, since all the decisions are taken based on audit_pid value only. Later, if the audit tools will bind the socket themselves, the kernel will have to provide a way to setup the audit_nlk_pid as well. A good side effect of this patch is that audit_pid can later be converted to struct pid, as it is not longer safe to use pid_t-s in the presence of pid namespaces. But audit code still uses the tgid from task_struct in the audit_signal_info and in the audit_filter_syscall.

This is due to the change of permissions of /proc/net that was introduced in that commit. Before: dr-xr-xr-x 5 root root 0 Mar 19 11:30 /proc/net After: dr-xr--r-- 5 root root 0 Mar 19 11:29 /proc/self/net This patch restores the permissions to the old value which makes ganglia happy again. Pavel Emelyanov says: This also broke the postfix, as it was reported in bug #10286 and described in detail by Benjamin.

| * | [SCTP]: Fix a race between module load and protosw accessVlad Yasevich2008-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race is SCTP between the loading of the module and the access by the socket layer to the protocol functions. In particular, a list of addresss that SCTP maintains is not initialized prior to the registration with the protosw. Thus it is possible for a user application to gain access to SCTP functions before everything has been initialized. The problem shows up as odd crashes during connection initializtion when we try to access the SCTP address list. The solution is to refactor how we do registration and initialize the lists prior to registering with the protosw. Care must be taken since the address list initialization depends on some other pieces of SCTP initialization. Also the clean-up in case of failure now also needs to be refactored.

| * | [NETFILTER]: ipt_recent: sanity check hit countDaniel Hokka Zakrisson2008-03-20

This patch makes ipt_recent refuse to create such rules. With ip_pkt_list_tot's default value of 20, the following can be used to reproduce the problem. nc -u -l 0.0.0.0 1234 & for i in `seq 1 100`; do echo $i | nc -w 1 -u 127.0.0.1 1234; done This limits it to 20 packets: iptables -A OUTPUT -p udp --dport 1234 -m recent --set --name test \ --rsource iptables -A OUTPUT -p udp --dport 1234 -m recent --update --seconds \ 60 --hitcount 20 --name test --rsource -j DROP While this is unlimited: iptables -A OUTPUT -p udp --dport 1234 -m recent --set --name test \ --rsource iptables -A OUTPUT -p udp --dport 1234 -m recent --update --seconds \ 60 --hitcount 21 --name test --rsource -j DROP With the patch the second rule-set will throw an EINVAL.
