* [SG] Get rid of __sg_mark_end()Jens Axboe2007-11-02
| | | | | | | | | | | | sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit. Add a sg_magic debug check as well, and clear a chain pointer if it is set. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* [NET]: Hide the net_ns kmem cachePavel Emelyanov2007-11-01
| | | | | | | | | | This cache is only required to create new namespaces, but we won't have them in CONFIG_NET_NS=n case. Hide it under the appropriate ifdef. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Mark the setup_net as __net_initPavel Emelyanov2007-11-01
| | | | | | | | | | | | | | | | | The setup_net is called for the init net namespace only (int the CONFIG_NET_NS=n of course) from the __init function, so mark it as __net_init to disappear with the caller after the boot. Yet again, in the perfect world this has to be under #ifdef CONFIG_NET_NS, but it isn't guaranteed that every subsystem is registered *after* the init_net_ns is set up. After we are sure, that we don't start registering them before the init net setup, we'll be able to move this code under the ifdef.

* [NET]: Hide the dead code in the net_namespace.cPavel Emelyanov2007-11-01
| | | | | | | | | | | | | | | | | | The namespace creation/destruction code is never called if the CONFIG_NET_NS is n, so it's OK to move it under appropriate ifdef. The copy_net_ns() in the "n" case checks for flags and returns -EINVAL when new net ns is requested. In a perfect world this stub must be in net_namespace.h, but this function need to know the CLONE_NEWNET value and thus requires sched.h. On the other hand this header is to be injected into almost every .c file in the networking code, and making all this code depend on the sched.h is a suicidal attempt.

* [NETNS]: Make the init/exit hooks checks outside the loopPavel Emelyanov2007-11-01
| | | | | | | | | | | | | | | | When the new pernet something (subsys, device or operations) is being registered, the init callback is to be called for each namespace, that currently exitst in the system. During the unregister, the same is to be done with the exit callback. However, not every pernet something has both calls, but the check for the appropriate pointer to be not NULL is performed inside the for_each_net() loop. This is (at least) strange, so tune this.

* [NET]: Forget the zero_it argument of sk_alloc()Pavel Emelyanov2007-11-01
| | | | | | | | | | | | | | | Finally, the zero_it argument can be completely removed from the callers and from the function prototype.

* [NET]: Move some core sock setup into sk_prot_allocPavel Emelyanov2007-11-01
| | | | | | | | | | | | | | | The security_sk_alloc() and the module_get is a part of the object allocations - move it in the proper place. Note, that since we do not reset the newly allocated sock in the sk_alloc() (memset() is removed with the previous patch) we can safely do this.

* [TCP]: Process DSACKs that reside within a SACK blockIlpo Järvinen2007-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DSACK inside another SACK block were missed if start_seq of DSACK was larger than SACK block's because sorting prioritizes full processing of the SACK block before DSACK. After SACK block sorting situation is like this: SSSSSSSSS D SSSSSS SSSSSSS Because write_queue is walked in-order, when the first SACK block has been processed, TCP is already past the skb for which the DSACK arrived and we haven't taught it to backtrack (nor should we), so TCP just continues processing by going to the next SACK block after the DSACK (if any). Whenever such DSACK is present, do an embedded checking during the previous SACK block. If the DSACK is below snd_una, there won't be overlapping SACK block, and thus no problem in that case. Also if start_seq of the DSACK is equal to the actual block, it will be processed first. Tested this by using netem to duplicate 15% of packets, and by printing SACK block when found_dup_sack is true and the selected skb in the dup_sack = 1 branch (if taken): SACK block 0: 4344-5792 (relative to snd_una 2019137317) SACK block 1: 4344-5792 (relative to snd_una 2019137317) equal start seqnos => next_dup = 0, dup_sack = 1 won't occur... SACK block 0: 5792-7240 (relative to snd_una 2019214061) SACK block 1: 2896-7240 (relative to snd_una 2019214061) DSACK skb match 5792-7240 (relative to snd_una) ...and next_dup = 1 case (after the not shown start_seq sort), went to dup_sack = 1 branch.

* [NET]: Fix incorrect sg_mark_end() calls.David S. Miller2007-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes scatterlist corruptions added by commit 68e3f5dd4db62619fdbe520d36c9ebf62e672256 [CRYPTO] users: Fix up scatterlist conversion errors The issue is that the code calls sg_mark_end() which clobbers the sg_page() pointer of the final scatterlist entry. The first part fo the fix makes skb_to_sgvec() do __sg_mark_end(). After considering all skb_to_sgvec() call sites the most correct solution is to call __sg_mark_end() in skb_to_sgvec() since that is what all of the callers would end up doing anyways. I suspect this might have fixed some problems in virtio_net which is the sole non-crypto user of skb_to_sgvec(). Other similar sg_mark_end() cases were converted over to __sg_mark_end() as well. Arguably sg_mark_end() is a poorly named function because it doesn't just "mark", it clears out the page pointer as a side effect, which is what led to these bugs in the first place. The one remaining plain sg_mark_end() call is in scsi_alloc_sgtable() and arguably it could be converted to __sg_mark_end() if only so that we can delete this confusing interface from linux/scatterlist.h Signed-off-by: David S.

* [NETNS]: fix net released by rcu callbackDaniel Lezcano2007-10-31
| | | | | | | | | | | | | | | | | | When a network namespace reference is held by a network subsystem, and when this reference is decremented in a rcu update callback, we must ensure that there is no more outstanding rcu update before trying to free the network namespace. In the normal case, the rcu_barrier is called when the network namespace is exiting in the cleanup_net function. But when a network namespace creation fails, and the subsystems are undone (like the cleanup), the rcu_barrier is missing. This patch adds the missing rcu_barrier.

* [NET]: Fix free_netdev on register_netdev failure.Daniel Lezcano2007-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Point 1: The unregistering of a network device schedule a netdev_run_todo. This function calls dev->destructor when it is set and the destructor calls free_netdev. Point 2: In the case of an initialization of a network device the usual code is: * alloc_netdev * register_netdev -> if this one fails, call free_netdev and exit with error. Point 3: In the register_netdevice function at the later state, when the device is at the registered state, a call to the netdevice_notifiers is made. If one of the notification falls into an error, a rollback to the registered state is done using unregister_netdevice. Conclusion: When a network device fails to register during initialization because one network subsystem returned an error during a notification call chain, the network device is freed twice because of fact 1 and fact 2. The second free_netdev will be done with an invalid pointer. Proposed solution: The following patch move all the code of unregister_netdevice *except* the call to net_set_todo, to a new function "rollback_registered". The following functions are changed in this way: * register_netdevice: calls rollback_registered when a notification fails * unregister_netdevice: calls rollback_register + net_set_todo, the call order to net_set_todo is changed because it is the latest now. Since it justs add an element to a list that should not break anything. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* [TCP]: Saner thash_entries default with much memory.Jean Delvare2007-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems with a very large amount of memory, the heuristics in alloc_large_system_hash() result in a very large TCP established hash table: 16 millions of entries for a 128 GB ia64 system. This makes reading from /proc/net/tcp pretty slow (well over a second) and as a result netstat is slow on these machines. I know that /proc/net/tcp is deprecated in favor of tcp_diag, however at the moment netstat only knows of the former. I am skeptical that such a large TCP established hash is often needed. Just because a system has a lot of memory doesn't imply that it will have several millions of concurrent TCP connections. Thus I believe that we should put an arbitrary high limit to the size of the TCP established hash by default. Users who really need a bigger hash can always use the thash_entries boot parameter to get more. I propose 2 millions of entries as the arbitrary high limit. This makes /proc/net/tcp reasonably fast on the system in question (0.2 s) while being still large enough for me to be confident that network performance won't suffer. This is just one way to limit the hash size, there are others; I am not familiar enough with the TCP code to decide which is best. Thus, I would welcome the proposals of alternatives. [ 2 million is still too large, thus I've modified the limit in the change to be '512 * 1024'. -DaveM ] Signed-off-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: David S.

* [NET]: Marking struct pernet_operations __net_initdata was inappropriateEric W. Biederman2007-10-27
| | | | | | | | | | | | | | | | | | It is not safe to to place struct pernet_operations in a special section. We need struct pernet_operations to last until we call unregister_pernet_subsys. Which doesn't happen until module unload. So marking struct pernet_operations is a disaster for modules in two ways. - We discard it before we call the exit method it points to. - Because I keep struct pernet_operations on a linked list discarding it for compiled in code removes elements in the middle of a linked list and does horrible things for linked insert.
