* [NET/IPV4/IPV6]: Change some sysctl variables to __read_mostlyBrian Haley2006-09-222-6/+6
| | | | | | | | | | Change net/core, ipv4 and ipv6 sysctl variables to __read_mostly. Couldn't actually measure any performance increase while testing (.3% I consider noise), but seems like the right thing to do. Signed-off-by: Brian Haley <brian.haley@hp.com> Signed-off-by: David S.

* [NET]: Introduce RTA_TABLE/FRA_TABLE attributesPatrick McHardy2006-09-221-2/+3
| | | | | | | | | | | | Introduce RTA_TABLE route attribute and FRA_TABLE routing rule attribute to hold 32 bit routing table IDs. Usespace compatibility is provided by continuing to accept and send the rtm_table field, but because of its limited size it can only carry the low 8 bits of the table ID. This implies that if larger IDs are used, _all_ userspace programs using them need to use RTA_TABLE. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| | | | | | | | | | | Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose checksum still needs to be completed) and CHECKSUM_COMPLETE (for incoming packets, device supplied full checksum).

* [NET]: Convert link dumping to new netlink apiThomas Graf2006-09-221-144/+137
| | | | | | | | | | | | | Transforms netlink code to dump link tables to use the new netlink api. Makes rtnl_getlink() available regardless of the availability of the wireless extensions. Adding copy_rtnl_link_stats() avoids the structural dependency of struct rtnl_link_stats on struct net_device_stats and thus avoids troubles later on.

A warning message printed to the console is added in the event that a change request fails while part of the change request has been comitted already. The ioctl() based nature of net devices makes it almost impossible to move on to atomic netlink operations without obsoleting some of the functionality.

| | | | | | | | | | | | | This adds security for IP sockets at the sock level. Security at the sock level is needed to enforce the SELinux security policy for security associations even when a sock is orphaned (such as in the TCP LAST_ACK state). This will also be used to enforce SELinux controls over data arriving at or leaving a child socket while it's still waiting to be accepted.

CPU1 CPU2 dst_run_gc() entered dst_run_gc() entered spin_lock(&dst_lock) ..... del_timer(&dst_gc_timer) fail to get lock .... mod_timer() <--- puts timer back to the list add_timer(&dst_gc_timer) <--- BUG because timer is in list already. Found during OpenVZ internal testing. At first we thought that it is OpenVZ specific as we added dst_run_gc(0) call in dst_dev_event(), but as Alexey pointed to me it is possible to trigger this condition in mainstream kernel. F.e. timer has fired on CPU2, but the handler was preeempted by an irq before dst_lock is tried. Meanwhile, someone on CPU1 adds an entry to gc list and starts the timer. If CPU2 was preempted long enough, this timer can expire simultaneously with resuming timer handler on CPU1, arriving exactly to the situation described.

* [NET]: Kill the WARN_ON() calls for checksum fixups.David S. Miller2006-08-021-10/+0
| | | | | | | | | | | | | | | | | We have a more complete solution in the works, involving the seperation of CHECKSUM_HW on input vs. output, and having netfilter properly do incremental checksums. But that is a very involved patch and is thus 2.6.19 material. What we have now is infinitely better than the past, wherein all TSO packets were dropped due to corrupt checksums as soon at the NAT module was loaded. At least now, the checksums do get fixed up, it just isn't the cleanest nor most optimal solution. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | When the trim point is within the head and there is no paged data, ___pskb_trim fails to drop the first element in the frag_list.

* [NET]: Update frag_list in pskb_trimHerbert Xu2006-07-131-26/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of the packet, the frag_list is not updated to reflect the trimming. This will usually work fine until you hit something that uses the packet length or tail from the frag_list. Examples include esp_output and ip_fragment. Another problem caused by this is that you can end up with a linear packet with a frag_list attached. It is possible to get away with this if we audit everything to make sure that they always consult skb->len before going down onto frag_list. In fact we can do the samething for the paged part as well to avoid copying the data area of the skb. For now though, let's do the conservative fix and update frag_list.
