2008-08-13pktgen: prevent pktgen from using bad tx queueAndrew Gallatin
With the new multi-queue transmit code, it is possible to accidentally make pktgen pick a non-existing tx queue simply by using a stale script to drive pktgen. Access to this non-existing tx queue will then trigger a bad memory access and kill the machine. For example, setting "queue_map_max 2" will cause my machine to die when accessing a garbage spinlock in the non-existing tx queue: BUG: spinlock bad magic on CPU#0, kpktgend_0/564 lock: ffff88001ddf6718, .magic: ffffffff, .owner: /-1, .owner_cpu: 0 Pid: 564, comm: kpktgend_0 Not tainted 2.6.27-rc3 #35 Call Trace: [<ffffffff803a1228>] spin_bug+0xa4/0xac [<ffffffff803a1253>] _raw_spin_lock+0x23/0x123 [<ffffffff8055b06f>] _spin_lock_bh+0x17/0x1b [<ffffffff804cb57d>] pktgen_thread_worker+0xa97/0x1002 [<ffffffff8022874d>] ? finish_task_switch+0x38/0x97 [<ffffffff80242077>] ? autoremove_wake_function+0x0/0x36 [<ffffffff80242077>] ? autoremove_wake_function+0x0/0x36 [<ffffffff804caae6>] ? pktgen_thread_worker+0x0/0x1002 [<ffffffff80241a40>] kthread+0x44/0x6d [<ffffffff8020c399>] child_rip+0xa/0x11 [<ffffffff802419fc>] ? kthread+0x0/0x6d [<ffffffff8020c38f>] ? child_rip+0x0/0x11 The attached patch adds some sanity checking to prevent these sorts of configuration errors.

2008-08-13net/rxrpc: Use an IS_ERR test rather than a NULL testJulien Brunel
In case of error, the function rxrpc_get_transport returns an ERR pointer, but never returns a NULL pointer. So after a call to this function, a NULL test should be replaced by an IS_ERR test. A simplified version of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @correct_null_test@ expression x,E; statement S1, S2; @@ x = rxrpc_get_transport(...) <... when != x = E if ( ( - x@p2 != NULL + !

2008-08-11ipvs: Explictly clear ip_vs_stats membersSimon Horman
In order to align the coding styles of ip_vs_zero_stats() and its child-function ip_vs_zero_estimator(), clear ip_vs_stats members explicitlty rather than doing a limited memset(). This was chosen over modifying ip_vs_zero_estimator() to use memset() as it is more robust against changes in members in the relevant structures. memset() would be prefered if all members of the structure were to be cleared.

2008-08-11ipvs: Embed estimator object into stats objectSven Wegener
There's no reason for dynamically allocating an estimator object for every stats object. Directly embed an estimator object into every stats object and switch to using the kernel-provided list implementation. This makes the code much simpler and faster, as we do not need to traverse the list of all estimators to find the one belonging to a stats object. There's no need to use an rwlock, as we only have one reader. Also reorder the members of the estimator structure slightly to avoid padding overhead. This can't be done with the stats object as the members are currently copied to our user space object via memcpy() and changing it would break ABI.

2008-08-11ipvs: Fix possible deadlock in estimator codeSven Wegener
There is a slight chance for a deadlock in the estimator code. We can't call del_timer_sync() while holding our lock, as the timer might be active and spinning for the lock on another cpu. Work around this issue by using try_to_del_timer_sync() and releasing the lock. We could actually delete the timer outside of our lock, as the add and kill functions are only every called from userspace via [gs]etsockopt() and are serialized by a mutex, but better make this explicit.

2008-08-09udp: Drop socket lock for encapsulated packetsHerbert Xu
The socket lock is there to protect the normal UDP receive path. Encapsulation UDP sockets don't need that protection. In fact the locking is deadly for them as they may contain another UDP packet within, possibly with the same addresses. Also the nested bit was copied from TCP. TCP needs it because of accept(2) spawning sockets. This simply doesn't apply to UDP so I've removed it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

Now we deal with mesh forwarding before the 802.11->802.3 conversion, thus eliminating a few unnecessary steps. The next hop lookup is called from ieee80211_master_start_xmit() instead of subif_start_xmit(). Until the next hop is found, RA in the frame will be all zeroes for frames originating from the device. For forwarded frames, RA will contain the TA of the received frame, which will be necessary to send a path error if a next hop is not found.

2008-08-07pktgen: multiqueue etc.Robert Olsson
Sofar far pktgen have had a restriction to only use one device per kernel thread. With the new multiqueue architecture this is no longer adequate. The patch below is an effort to remove this by in pktgen configuration adding a tag to the device name a la eth0@0 etc. The tag is used for usual device config just as before. Also a new flag is introduced to mirror queue_map with sending threads smp_processor_id() QUEUE_MAP_CPU. An example: We use 4 CPU's to send to one 10g interface (eth0) and we use the new tagging to send a mix of packet sizes, 64, 576 and 1500 bytes. Also we use TX queues according to smp_processor_id() PGDEV=/proc/net/pktgen/kpktgend_0 pgset "add_device eth0@0" PGDEV=/proc/net/pktgen/kpktgend_1 pgset "add_device eth0@1" PGDEV=/proc/net/pktgen/kpktgend_2 pgset "add_device eth0@2" PGDEV=/proc/net/pktgen/kpktgend_3 pgset "add_device eth0@3" ....

2008-08-05AX.25: Fix sysctl registration if !CONFIG_AX25_DAMA_SLAVERalf Baechle
Since 49ffcf8f99e8d33ec8afb450956804af518fd788 ("sysctl: update sysctl_check_table") setting struct ctl_table.procname = NULL does no longer work as it used to the way the AX.25 code is expecting it to resulting in the AX.25 sysctl registration code to break if CONFIG_AX25_DAMA_SLAVE was not set as in some distribution kernels. Kernel releases from 2.6.24 are affected. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-05bridge: Eliminate unnecessary forward delayStephen Hemminger
From: Stephen Hemminger <shemminger@vyatta.com> Based upon original patch by Herbert Xu, which contained the following problem description: -------------------- When the forward delay is set to zero, we still delay the setting of the forwarding state by one or possibly two timers depending on whether STP is enabled. This could either turn out to be instantaneous, or horribly slow depending on the load of the machine. As there is nothing preventing us from enabling forwarding straight away, this patch eliminates this potential delay by executing the code directly if the forward delay is zero. The effect of this problem is that immediately after the carrier comes on a port, the bridge will drop all packets received from that port until it enters forwarding mode, thus causing unnecessary packet loss. Note that this patch doesn't fully remove the delay due to the link watcher. We should also check the carrier state when we are about to drop an incoming packet because the port is disabled. But that's for another patch. -------------------- This version of the fix takes a different approach, in that it just does the state change directly. Signed-off-by: David S.

Patrick McHardy <kaber@trash.net> noticed that it would be nice to handle NET_XMIT_BYPASS by NET_XMIT_SUCCESS with an internal qdisc flag __NET_XMIT_BYPASS and to remove the mapping from dev_queue_xmit().
