* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-308-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* | IPoIB: Fix TX queue lockup with mixed UD/CM trafficEli Cohen2010-03-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IPoIB UD QP reports send completions to priv->send_cq, which is usually left unarmed; it only gets armed when the number of outstanding send requests reaches the size of the TX queue. This arming is done only in the send path for the UD QP. However, when sending CM packets, the net queue may be stopped for the same reasons but no measures are taken to recover the UD path from a lockup. Consider this scenario: a host sends high rate of both CM and UD packets, with a TX queue length of N. If at some time the number of outstanding UD packets is more than N/2 and the overall outstanding packets is N-1, and CM sends a packet (making the number of outstanding sends equal N), the TX queue will be stopped. When all the CM packets complete, the number of outstanding packets will still be higher than N/2 so the TX queue will not be restarted. Fix this by calling ib_req_notify_cq() when the queue is stopped in the CM path. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Change this to post only when the number of outstanding recv buffers is below a water mark and in a batched manner, thus simplifying and optimizing the data path. Use a pre-allocated ring of recv buffers instead of allocating from kmem cache.

The problem is caused when ipoib_neigh->dgid contains a stale address. The fix is to set ipoib_neigh->dgid to zero in ipoib_neigh_alloc(). This can happen when a system using bonding on its IPoIB interfaces has switched its active interface from interface A to B and back to A. The system that fails over will not correctly processes the 2nd address change, as described below. When an address has changed neighbor->ha is updated with the new address. Each neighbor has an associated ipoib_neigh. ipoib_neigh->dgid also holds a copy of the remote node's hardware address. When an address changes neighbor->ha is updated by the network layer (arp code) with the new address. IPoIB detects this change in ipoib_start_xmit() by comparing neighbor->ha with ipoib_neigh->dgid. The bug is that ipoib_neigh->dgid may already contain the new address (A) thus the change from B to A is missed by ipoib. Here is the sequence of events: ipoib_neigh->dgid = A and neighbor->ha = A The address is switched to B (the first switch) neighbor->ha = B The change is seen in ipoib_start_xmit() -- neighbor->ha != ipoib_neigh->dgid so ipoib_neigh is released, and a new one is allocated. The allocator may return the same chunk of memory that was just released, therefore ipoib_neigh->dgid still contains A at this point. ipoib_neigh->dgid should be updated in neigh_add_path(), but if the following conditions are true dgid is not updated: 1) __path_find() returns a path 2) path->ah is NULL The remote system now switches from address B to A, neighbor->ha is updated to A. Now we have again : ipoib_neigh->dgid = A and neighbor->ha = A Since the addresses are the same ipoib won't process the change in address. Fix this by zeroing out the dgid field when allocating a new struct ipoib_neigh. Signed-off-by: David Wilder <dwilder@us.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multicast joins can succeed even if the IB port is down. This happens when the SM runs on the same port with the requesting port. However, IPoIB calls netif_carrier_on() when the join of the broadcast group succeeds, without caring about the state of the IB port. The result is an IPoIB interface in RUNNING state but without an active IB port to support it. If a bonding interface uses this IPoIB interface as a slave it might not detect that this slave is almost useless and failover functionality will be damaged. The fix checks the state of the IB port in the carrier_task before calling netif_carrier_on().

Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to <asm-generic/socket.h> in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use. Noted in 'next' by Stephen Rothwell.

| | | | | | | | | | | | | | | | | | | | Check that the format of multicast link addresses is correct before taking them from dev->mc_list to priv->multicast_list. This way we never try to send a bogus address to the SA, which prevents badness from erronous 'ip maddr addr add', broken bonding drivers, etc. Signed-off-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* | IPoIB: Drop priv->lock before calling ipoib_send()Roland Dreier2009-09-052-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | IPoIB currently must use irqsave locking for priv->lock, since it is taken from interrupt context in one path. However, ipoib_send() does skb_orphan(), and the network stack locking is not IRQ-safe. Therefore we need to make sure we don't hold priv->lock when calling ipoib_send() to avoid lockdep warnings (the code was almost certainly safe in practice, since the only code path that takes priv->lock from interrupt context would never call into the network stack).

| * [SCSI] libiscsi: add task aborted stateMike Christie2009-05-231-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | If a task did not complete normally due to a TMF, libiscsi will now complete the task with the state ISCSI_TASK_ABRT_TMF. Drivers like bnx2i that need to free resources if a command did not complete normally can then check the task state. If a driver does not need to send a special command if we have dropped the session then they can check for ISCSI_TASK_ABRT_SESS_RECOV.

| * [SCSI] iscsi: pass ep connect shostMike Christie2009-05-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we create the tcp/ip connection by calling ep_connect, we currently just go by the routing table info. I think there are two problems with this. 1. Some drivers do not have access to a routing table. Some drivers like qla4xxx do not even know about other ports. 2. If you have two initiator ports on the same subnet, the user may have set things up so that session1 was supposed to be run through port1. and session2 was supposed to be run through port2. It looks like we could end with both sessions going through one of the ports. Fixes for cxgb3i from Karen Xie.

* | IPoIB: Disable NAPI while CQ is being drainedYossi Etigin2009-04-202-6/+5
|/ | | | | | | | | | | | | | | | If NAPI is enabled while IPoIB's CQ is being drained, it creates a race on priv->ibwc between ipoib_poll() and ipoib_drain_cq(), leading to memory corruption. The solution is to enable/disable NAPI in ipoib_ib_dev_{open/stop}() instead of in ipoib_{open/stop}(), and sync NAPI on the INITIALIZED flag instead on the ADMIN_UP flag. This way NAPI will be disabled when ipoib_drain_cq() is called. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1587>.
