2009-10-20filter: Add SKF_AD_QUEUE instructionEric Dumazet
It can help being able to filter packets on their queue_mapping. If filter performance is not good, we could add a "numqueue" field in struct packet_type, so that netif_nit_deliver() and other functions can directly ignore packets with not expected queue number. Lets experiment this simple filter extension first. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-20can: provide library functions for skb allocationWolfgang Grandegger
This patch makes the private functions alloc_can_skb() and alloc_can_err_skb() of the at91_can driver public and adapts all drivers to use these. While making the patch I realized, that the skb's are *not* setup consistently. It's now done as shown below: skb->protocol = htons(ETH_P_CAN); skb->pkt_type = PACKET_BROADCAST; skb->ip_summed = CHECKSUM_UNNECESSARY; *cf = (struct can_frame *)skb_put(skb, sizeof(struct can_frame)); memset(*cf, 0, sizeof(struct can_frame)); The frame is zeroed out to avoid uninitialized data to be passed to user space. Some drivers or library code did not set "pkt_type" or "ip_summed". Also, "__constant_htons()" should not be used for runtime invocations, as pointed out by David Miller.

2009-10-19wimax/i2400m: fix reboot echo/ack barker deadlockInaky Perez-Gonzalez
The i2400m based devices can get in a sort of a deadlock some times; when they boot, they send a reboot "barker" (a magic number) and then the driver has to echo that same barker to ack reception (echo/ack). Then the device does a final ack by sending an ACK barker. The first time this happens, we don't know ahead of time with barker the device is going to send, as different device models and SKUs will send different barker depending on the EEPROM programming. If the device has sent the barker before the driver has been able to read it, the driver looses, as it doesn't know which barker it has to echo/ack back. With older devices, we tried a couple of combinations and that always worked; but now, with adding support for more, in which we have an unlimited number of new barkers, that is not an option. So we rework said case so that when the device gets stuck, we just cycle through all the known types until one forces the device to send an ack. Otherwise, the driver gives up and aborts.

2009-10-19wimax/i2400m: decide properly if using signed vs non-signed firmware loadingInaky Perez-Gonzalez
The i2400m based devices can boot two main types of firmware images: signed and non-signed. Signed images have signature data included that must match that of a certificate stored in the device. Currently the code is making the decission on what type of firmware load (signed vs non-signed) is going to be loaded based on a hardcoded decission in __i2400m_ack_verify(), based on the barker the device sent upon boot. This is not flexible enough as future hardware will emit more barkers; thus the bit has to be set in a place where there is better knowledge of what is going on. This will be done in follow-up commits -- however this patch paves the way for it. So the querying of the mode is packed into i2400m_boot_is_signed(); the main changes are just using i2400m_boot_is_signed() to determine the method to follow and setting i2400m->sboot in i2400m_is_boot_barker(). The modifications in i2400m_dnload_init() and i2400m_dnload_finalize() are just reorganizing the order of the if blocks and thus look larger than they really are.

2009-10-19wimax: allow specifying debug levels as command line optionInaky Perez-Gonzalez
Add "debug" module options to all the wimax modules (including drivers) so that the debug levels can be set upon kernel boot or module load time. This is needed as currently there was a limitation where the debug levels could only be set when a device was succesfully enumerated. This made it difficult to debug issues that made a device not probe properly. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>

2009-10-18inet: rename some inet_sock fieldsEric Dumazet
In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-10-14firewire: core: optimize Topology Map creationStefan Richter
The Topology Map of the local node was created in CPU byte order, then a temporary big endian copy was created to compute the CRC, and when a read request to the Topology Map arrived it had to be converted to big endian byte order again.

The config ROM image of the local node was created in CPU byte order, then a temporary big endian copy was created to compute the CRC, and finally the card driver created its own big endian copy. We now generate it in big endian byte order in the first place to avoid one byte order conversion and the temporary on-stack copy of the ROM image (1000 bytes stack usage in process context). Furthermore, two 1000 bytes memset()s are replaced by one 1000 bytes - ROM length sized memset. The trivial fw_memcpy_{from,to}_be32() helpers are now superfluous and removed. The newly added __compute_block_crc() function will be folded into fw_compute_block_crc() in a subsequent change. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2009-10-12net: Introduce recvmmsg socket syscallArnaldo Carvalho de Melo
Meaning receive multiple messages, reducing the number of syscalls and net stack entry/exit operations. Next patches will introduce mechanisms where protocols that want to optimize this operation will provide an unlocked_recvmsg operation. This takes into account comments made by: . Paul Moore: sock_recvmsg is called only for the first datagram, sock_recvmsg_nosec is used for the rest. . Caitlin Bestler: recvmmsg now has a struct timespec timeout, that works in the same fashion as the ppoll one. If the underlying protocol returns a datagram with MSG_OOB set, this will make recvmmsg return right away with as many datagrams (+ the OOB one) it has received so far. . Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen datagrams and then recvmsg returns an error, recvmmsg will return the successfully received datagrams, store the error and return it in the next call. This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg, where we will be able to acquire the lock only at batch start and end, not at every underlying recvmsg call.

2009-10-12net: Generalize socket rx gap / receive queue overflow cmsgNeil Horman
Create a new socket level option to report number of queue overflows Recently I augmented the AF_PACKET protocol to report the number of frames lost on the socket receive queue between any two enqueued frames. This value was exported via a SOL_PACKET level cmsg. AFter I completed that work it was requested that this feature be generalized so that any datagram oriented socket could make use of this option. As such I've created this patch, It creates a new SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a SOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue overflowed between any two given frames. It also augments the AF_PACKET protocol to take advantage of this new feature (as it previously did not touch sk->sk_drops, which this patch uses to record the overflow count). Tested successfully by me. Notes: 1) Unlike my previous patch, this patch simply records the sk_drops value, which is not a number of drops between packets, but rather a total number of drops. Deltas must be computed in user space. 2) While this patch currently works with datagram oriented protocols, it will also be accepted by non-datagram oriented protocols. I'm not sure if thats agreeable to everyone, but my argument in favor of doing so is that, for those protocols which aren't applicable to this option, sk_drops will always be zero, and reporting no drops on a receive queue that isn't used for those non-participating protocols seems reasonable to me. This also saves us having to code in a per-protocol opt in mechanism. 3) This applies cleanly to net-next assuming that commit 977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-10-12LSM: Add security_path_chmod() and security_path_chown().Tetsuo Handa
This patch allows pathname based LSM modules to check chmod()/chown() operations. Since notify_change() does not receive "struct vfsmount *", we add security_path_chmod() and security_path_chown() to the caller of notify_change(). These hooks are used by TOMOYO.
