| * [PATCH] net: swich device attribute creation to default attrsKay Sievers2006-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent udev versions don't longer cover bad sysfs timing with built-in logic. Explicit rules are required to do that. For net devices, the following is needed: ACTION=="add", SUBSYSTEM=="net", WAIT_FOR_SYSFS="address" to handle access to net device properties from an event handler without races. This patch changes the main net attributes to be created by the driver core, which is done _before_ the event is sent out and will not require the stat() loop of the WAIT_FOR_SYSFS key.

| * [PATCH] driver core: replace "hotplug" by "uevent"Kay Sievers2006-01-04
| | | | | | | | | | | | | | | | | | Leave the overloaded "hotplug" word to susbsystems which are handling real devices. The driver core does not "plug" anything, it just exports the state to userspace and generates events.

If it's not [e.g. DCCP_PARTOPEN] upper layers will perform sanity checks and parse options. If it is in DCCP_OPEN, dccp_rcv_established() will do it. It is important not to re-parse options in dccp_rcv_established() when it is not called from the fast-path. Else, fore example, the ack vector will be added twice and the CCID will see the packet twice. The solution is to always enfore sanity checks from the upper layers. When packets arrive in the fast-path, sanity checks will be performed before calling dccp_rcv_established(). Note(acme): I rewrote the patch to achieve the same result but keeping dccp_rcv_established with the previous semantics and having it split into __dccp_rcv_established, that doesn't does do any sanity check, code in state != DCCP_OPEN use this lighter version as they already do the sanity checks.

VMS seems to behave similarly: if I bring up a VMS node with no router then it can't see anything else on the global network.

Fix this by using a pointer to refer to skb_shared_info. By initializing skb_shared_info sequentially, the write combining buffers can reduce the number of memory transactions to a single write. Reorder the initialization in __alloc_skb() to match the structure definition. There is also an alignment issue on 64 bit systems with skb_shared_info by converting nr_frags to a short everything packs up nicely. Also, pass the slab cache pointer according to the fclone flag instead of using two almost identical function calls. This raises bw_unix performance up to a peak of 707KB/s when combined with the spinlock patch. It should help other networking protocols, too. Signed-off-by: David S. Miller <davem@davemloft.net>

* | | | | | | | | | | [NET]: restructure sock_aio_{read,write} / sock_{readv,writev}Christoph Hellwig2006-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mid-term I plan to restructure the file_operations so that we don't need to have all these duplicate aio and vectored versions. This patch is a small step in that direction but also a worthwile cleanup on it's own: (1) introduce a alloc_sock_iocb helper that encapsulates allocating a proper sock_iocb (2) add do_sock_read and do_sock_write helpers for common read/write code Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S.

* | | | | | | | | | | [NET]: Fix sock_init() return value.David S. Miller2006-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It needs to return zero now that it is an initcall. Also, net/nonet.c no longer needs a dummy sock_init(). Signed-off-by: David S. Miller <davem@davemloft.net>
* | | | | | | | | | | [PKTGEN]: Deinitialise static variables.Jaco Kroon2006-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | static variables should not be explicitly initialised to 0. This causes them to be placed in .data instead of .bss. This patch de-initialises 3 static variables in net/core/pktgen.c. There are approximately 800 more such variables in the source tree (2.6.15rc5). If there is more interrest I'd be willing to track down the rest of these as well and de-initialise them as well.

* | | | | | | | | | | [NET]: move struct proto_ops to constEric Dumazet2006-01-03

(default linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at least) This patch makes sure a 'struct proto_ops' can be declared as const, so that all cpus can share all parts of it without false sharing. This is not mandatory : a driver can still use a read/write structure if it needs to (and eventually a __read_mostly) I made a global stubstitute to change all existing occurences to make them const. This should reduce the possibility of false sharing on SMP, and speedup some socket system calls. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.
