| * | [NET]: Replace skb_pull/skb_postpull_rcsum with skb_pull_rcsumHerbert Xu2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're now starting to have quite a number of places that do skb_pull followed immediately by an skb_postpull_rcsum. We can merge these two operations into one function with skb_pull_rcsum. This makes sense since most pull operations on receive skb's need to update the checksum. I've decided to make this out-of-line since it is fairly big and the fast path where hardware checksums are enabled need to call csum_partial anyway. Since this is a brand new function we get to add an extra check on the len argument. As it is most callers of skb_pull ignore its return value which essentially means that there is no check on the len argument.

| * | [DECnet]: Endian annotation and fixes for DECnet.Steven Whitehouse2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The typedef for dn_address has been removed in favour of using __le16 or __u16 directly as appropriate. All the DECnet header files are updated accordingly. The byte ordering of dn_eth2dn() and dn_dn2eth() are both changed since just about all their callers wanted network order rather than host order, so the conversion is now done in the functions themselves. Several missed endianess conversions have been picked up during the conversion process. The nh_gw field in struct dn_fib_info has been changed from a 32 bit field to 16 bits as it ought to be. One or two cases of using htons rather than dn_htons in the routing code have been found and fixed. There are still a few warnings to fix, but this patch deals with the important cases.

| * | [SECURITY]: TCP/UDP getpeersecCatherine Zhang2006-03-21

Patch purpose: This patch enables a security-aware application to retrieve the security context of an IPSec security association a particular TCP or UDP socket is using. The application can then use this security context to determine the security context for processing on behalf of the peer at the other end of this connection. In the case of UDP, the security context is for each individual packet. An example application is the inetd daemon, which could be modified to start daemons running at security contexts dependent on the remote client. Patch design approach: - Design for TCP The patch enables the SELinux LSM to set the peer security context for a socket based on the security context of the IPSec security association. The application may retrieve this context using getsockopt. When called, the kernel determines if the socket is a connected (TCP_ESTABLISHED) TCP socket and, if so, uses the dst_entry cache on the socket to retrieve the security associations. If a security association has a security context, the context string is returned, as for UNIX domain sockets. - Design for UDP Unlike TCP, UDP is connectionless. This requires a somewhat different API to retrieve the peer security context. With TCP, the peer security context stays the same throughout the connection, thus it can be retrieved at any time between when the connection is established and when it is torn down. With UDP, each read/write can have different peer and thus the security context might change every time. As a result the security context retrieval must be done TOGETHER with the packet retrieval. The solution is to build upon the existing Unix domain socket API for retrieving user credentials. Linux offers the API for obtaining user credentials via ancillary messages (i.e., out of band/control messages that are bundled together with a normal message). Patch implementation details: - Implementation for TCP The security context can be retrieved by applications using getsockopt with the existing SO_PEERSEC flag. As an example (ignoring error checking): getsockopt(sockfd, SOL_SOCKET, SO_PEERSEC, optbuf, &optlen); printf("Socket peer context is: %s\n", optbuf); The SELinux function, selinux_socket_getpeersec, is extended to check for labeled security associations for connected (TCP_ESTABLISHED == sk->sk_state) TCP sockets only. If so, the socket has a dst_cache of struct dst_entry values that may refer to security associations. If these have security associations with security contexts, the security context is returned. getsockopt returns a buffer that contains a security context string or the buffer is unmodified. - Implementation for UDP To retrieve the security context, the application first indicates to the kernel such desire by setting the IP_PASSSEC option via getsockopt. Then the application retrieves the security context using the auxiliary data mechanism. An example server application for UDP should look like this: toggle = 1; toggle_len = sizeof(toggle); setsockopt(sockfd, SOL_IP, IP_PASSSEC, &toggle, &toggle_len); recvmsg(sockfd, &msg_hdr, 0); if (msg_hdr.msg_controllen > sizeof(struct cmsghdr)) { cmsg_hdr = CMSG_FIRSTHDR(&msg_hdr); if (cmsg_hdr->cmsg_len <= CMSG_LEN(sizeof(scontext)) && cmsg_hdr->cmsg_level == SOL_IP && cmsg_hdr->cmsg_type == SCM_SECURITY) { memcpy(&scontext, CMSG_DATA(cmsg_hdr), sizeof(scontext)); } } ip_setsockopt is enhanced with a new socket option IP_PASSSEC to allow a server socket to receive security context of the peer. A new ancillary message type SCM_SECURITY. When the packet is received we get the security context from the sec_path pointer which is contained in the sk_buff, and copy it to the ancillary message space. An additional LSM hook, selinux_socket_getpeersec_udp, is defined to retrieve the security context from the SELinux space. The existing function, selinux_socket_getpeersec does not suit our purpose, because the security context is copied directly to user space, rather than to kernel space. Testing: We have tested the patch by setting up TCP and UDP connections between applications on two machines using the IPSec policies that result in labeled security associations being built. For TCP, we can then extract the peer security context using getsockopt on either end. For UDP, the receiving end can retrieve the security context using the auxiliary data mechanism of recvmsg.

| * | [XFRM]: Fix aevent related crashPatrick McHardy2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When xfrm_user isn't loaded xfrm_nl is NULL, which makes IPsec crash because xfrm_aevent_is_on passes the NULL pointer to netlink_has_listeners as socket. A second problem is that the xfrm_nl pointer is not cleared when the socket is releases at module unload time. Protect references of xfrm_nl from outside of xfrm_user by RCU, check that the socket is present in xfrm_aevent_is_on and set it to NULL when unloading xfrm_user.

| * | [TCP]: sysctl to allow TCP window > 32767 sans wscaleRick Jones2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in the dark ages, we had to be conservative and only allow 15-bit window fields if the window scale option was not negotiated. Some ancient stacks used a signed 16-bit quantity for the window field of the TCP header and would get confused. Those days are long gone, so we can use the full 16-bits by default now. There is a sysctl added so that we can still interact with such old stacks Signed-off-by: Rick Jones <rick.jones2@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

I was getting a panic after a tg3 device failed to initialize due to DMA failure. The oops pointed to the link watch queue with spinlock debugging enabled. Without spinlock debugging, the Oops didn't occur. I suspect that the link event was getting queued but not executed until after the DMA test had failed and the device was freed. The link event was then operating on freed memory, which could contain anything. With this patch applied, the Oops no longer occurs.

See also chapter 14 in Documentation/CodingStyle. Before: text data bss dec hex filename 102990 5292 1752 110034 1add2 tipc.o Now: text data bss dec hex filename 101190 5292 1752 108234 1a6ca tipc.o This is a nice text size reduction which will improve icache usage. In some cases bigger (> 4 lines) functions where declared inline and used in many places, they are most probarly no longer inlined by gcc resulting in the size reduction. There are several one liners that no longer are declared inline, but gcc should inline these just fine without the inline hint. With this patch applied one warning is added about an unused static function - that was hidded by utilising inline before. The function in question were kept so this patch is solely a inline removal patch.

| | | | | | | | | | | | | | | | | | | | | Ethtool memory test on 5787 requires a new memory table. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | [TG3]: Add new one-shot MSI handlerMichael Chan2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support one-shot MSI on 5787. This one-shot MSI idea is credited to David Miller. In this mode, MSI disables itself automatically after it is generated, saving the driver a register access to disable it for NAPI.

| * | [TG3]: Add new hard_start_xmitMichael Chan2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support 5787 hardware TSO using a new flag TG3_FLG2_HW_TSO_2. Since the TSO interface is slightly different and these chips have finally fixed the 4GB DMA problem and do not have the 40-bit DMA problem, a new hard_start_xmit is used for these chips. All previous chips will use the old hard_start_xmit that is now renamed tg3_start_xmit_dma_bug(). Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * | [NET]: use fget_light() in net/socket.cBenjamin LaHaise2006-03-21

Rerunning the tests show a drop of ~80Mbit/s on average, which looks bad until you see the drop in cpu usage from ~89% to ~82%. That will get fixed in another patch...
