* [TG3]: Avoid an expensive divide.Eric Dumazet2007-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During an oprofile session of linux-2.6.20 on a dual opteron system, I noticed an expensive divide was done in tg3_poll(). I am using gcc-4.1.1, so the following comment from drivers/net/tg3.c seems over-optimistic : /* Do not place this n-ring entries value into the tp struct itself, * we really want to expose these constants to GCC so that modulo et * al. operations are done with shifts and masks instead of with * hw multiply/modulo instructions. Another solution would be to * replace things like '% foo' with '& (foo - 1)'. */ #define TG3_RX_RCB_RING_SIZE(tp) \ ((tp->tg3_flags2 & TG3_FLG2_5705_PLUS) ? 512 : 1024) Assembly code before patch : (oprofile results included) 6434 0.0088 :ffffffff803684b9: mov 0x6f0(%r15),%eax 587 8.0e-04 :ffffffff803684c0: and $0x40000,%eax 2170 0.0030 :ffffffff803684c5: cmp $0x1,%eax :ffffffff803684c8: lea 0x1(%r13),%eax :ffffffff803684cc: sbb %ecx,%ecx 2051 0.0028 :ffffffff803684ce: xor %edx,%edx :ffffffff803684d0: and $0x200,%ecx 20 2.7e-05 :ffffffff803684d6: add $0x200,%ecx 1986 0.0027 :ffffffff803684dc: div %ecx 103427 0.1410 :ffffffff803684de: cmp %edx,0xffffffffffffff7c(%rbp) Assembly code after the suggested patch : ffffffff803684b9: mov 0x6f0(%r15),%eax ffffffff803684c0: and $0x40000,%eax ffffffff803684c5: cmp $0x1,%eax ffffffff803684c8: sbb %eax,%eax ffffffff803684ca: inc %r13d ffffffff803684cd: and $0x200,%eax ffffffff803684d2: add $0x1ff,%eax ffffffff803684d7: and %eax,%r13d ffffffff803684da: cmp %r13d,0xffffffffffffff7c(%rbp) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Acked-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* [ATM]: Fix for crash in adummy_init()Daniel Walker2007-02-08
| | | | | | | | | | | | | | | | | | | This was reported by Ingo Molnar here, http://lkml.org/lkml/2006/12/18/119 The problem is that adummy_init() depends on atm_init() , but adummy_init() is called first. So I put atm_init() into subsys_initcall which seems appropriate, and it will still get module_init() if it becomes a module. Interesting to note that you could crash your system here if you just load the modules in the wrong order.

* [NET]: user of the jiffies rounding code: NetworkingArjan van de Ven2007-02-08
| | | | | | | | | | | | | | | | | | | | This patch introduces users of the round_jiffies() function in the networking code. These timers all were of the "about once a second" or "about once every X seconds" variety and several showed up in the "what wakes the cpu up" profiles that the tickless patches provide. Some timers are highly dynamic based on network load; but even on low activity systems they still show up so the rounding is done only in cases of low activity, allowing higher frequency timers in the high activity case. The various hardware watchdogs are an obvious case; they run every 2 seconds but aren't otherwise specific of exactly when they need to run.

* [TCP]: Check num sacks in SACK fast pathBaruch Even2007-02-08
| | | | | | | | | | We clear the unused parts of the SACK cache, This prevents us from mistakenly taking the cache data if the old data in the SACK cache is the same as the data in the SACK block.

* [TCP]: Seperate DSACK from SACK fast pathBaruch Even2007-02-08
| | | | | | | | | | | | | | Move DSACK code outside the SACK fast-path checking code. If the DSACK determined that the information was too old we stayed with a partial cache copied. Most likely this matters very little since the next packet will not be DSACK and we will find it in the cache. but it's still not good form and there is little reason to couple the two checks. Since the SACK receive cache doesn't need the data to be in host order we also remove the ntohl in the checking loop. Signed-off-by: Baruch Even <baruch@ev-en.org> Signed-off-by: David S.

* [PACKET]: Fix skb->cb clobbering between aux and sockaddrHerbert Xu2007-02-08
| | | | | | | | | | | | | Both aux data and sockaddr tries to use the same buffer which obviously doesn't work. We just happen to have 4 bytes free in the skb->cb if you take away the maximum length of sockaddr_ll. That's just enough to store the one piece of info from aux data that we can't generate at recvmsg(2) time. This is what the following patch does.

* [PACKET]: Add optional checksum computation for recvmsgHerbert Xu2007-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch is needed to make ISC's DHCP server (and probably other DHCP servers/clients using AF_PACKET) to be able to serve another client on the same Xen host. The problem is that packets between different domains on the same Xen host only have partial checksums. Unfortunately this piece of information is not passed along in AF_PACKET unless you're using the mmap interface. Since dhcpd doesn't support packet-mmap, UDP packets from the same host come out with apparently bogus checksums. This patch adds a mechanism for AF_PACKET recvmsg(2) to return the status along with the packet. It does so by adding a new cmsg that contains this information along with some other relevant data such as the original packet length. I didn't include the time stamp information since there is already a cmsg for that. This patch also changes the mmap code to set the CSUMNOTREADY flag on all packets instead of just outoing packets on cooked sockets.

While this is certainly a kernel bug, its not critical and crashing the kernel is too drastic, especially when considering that these errors have appeared multiple times in the past and it BUGs even if no listeners are present.

| * configfs: Zero terminate data in configfs attribute writes.Joel Becker2007-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Attributes in configfs are text files. As such, most handlers expect to be able to call functions like simple_strtoul() without checking the bounds of the buffer. Change the call to zero terminate the buffer before calling the client's ->store() method. This does reduce the attribute size from PAGE_SIZE to PAGE_SIZE-1. Also, change get_zeroed_page() to alloc_page(), as we are handling the termination. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * [PATCH] ocfs2 heartbeat: clean up bio submission codePhilipp Reisner2007-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As was already pointed out Mathieu Avila on Thu, 07 Sep 2006 03:15:25 -0700 that OCFS2 is expecting bio_add_page() to add pages to BIOs in an easily predictable manner. That is not true, especially for devices with own merge_bvec_fn(). Therefore OCFS2's heartbeat code is very likely to fail on such devices. Move the bio_put() call into the bio's bi_end_io() function. This makes the whole idea of trying to predict the behaviour of bio_add_page() unnecessary.

| * ocfs2: introduce sc->sc_send_lock to protect outbound outbound messagesZhen Wei2007-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is a lot of multithreaded I/O usage, two threads can collide while sending out a message to the other nodes. This is due to the lack of locking between threads while sending out the messages. When a connected TCP send(), sendto(), or sendmsg() arrives in the Linux kernel, it eventually comes through tcp_sendmsg(). tcp_sendmsg() protects itself by acquiring a lock at invocation by calling lock_sock(). tcp_sendmsg() then loops over the buffers in the iovec, allocating associated sk_buff's and cache pages for use in the actual send. As it does so, it pushes the data out to tcp for actual transmission. However, if one of those allocation fails (because a large number of large sends is being processed, for example), it must wait for memory to become available. It does so by jumping to wait_for_sndbuf or wait_for_memory, both of which eventually cause a call to sk_stream_wait_memory(). sk_stream_wait_memory() contains a code path that calls sk_wait_event(). Finally, sk_wait_event() contains the call to release_sock(). The following patch adds a lock to the socket container in order to properly serialize outbound requests.

| | | | | | | | | | | | | | | | | | | | Currently the ocfs2 dlm has no timeout during dlm join domain. While this is not a problem in normal operation, this does become an issue if, say, the other node is refusing to let the node join the domain because of a stuck recovery.

| * ocfs2_dlm: disallow a domain join if node maps mismatchSrinivas Eeda2007-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a small window where a joining node may not see the node(s) that just died but are still part of the domain. To fix this, we must disallow join requests if the joining node has a different node map. A new field node_map is added to dlm_query_join_request to send the current nodes nodemap along with join request. On the receiving end the nodes that are part of the cluster verifies if this new node sees all the nodes that are still part of the cluster. They disallow the join if the maps mismatch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following macro : include/asm-powerpc/vga.h:#define VGA_MAP_MEM(x,s) (x + vgacon_remap_base) is used by drivers/video/console/vgacon.c which can be compiled as a module (drivers/video/vga16fb.ko). Therefore, vgacon_remap_base should be exported. Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kernel/irq.c contains a comment that speaks of -1 and -2 as interrupt numbers, but this is actually dependent on configuration options now.
