| * af_iucv: do not call iucv_sock_kill() twiceHendrik Brueckner2009-09-16

This typically results in a kernel oops as shown below. Remove the duplicate call to iucv_sock_kill() and set the SOCK_ZAPPED flag in iucv_sock_close() only. The iucv_sock_kill() function frees a socket only if the socket is zapped and orphaned (sk->sk_socket == NULL): - Non-accepted sockets are always orphaned and, thus, iucv_sock_kill() frees the socket twice. - For accepted sockets or sockets created with iucv_sock_create(), sk->sk_socket is initialized. This caused the first call to iucv_sock_kill() to return immediately. To free these sockets, iucv_sock_release() uses sock_orphan() before calling iucv_sock_kill(). <1>Unable to handle kernel pointer dereference at virtual kernel address 000000003edd3000 <4>Oops: 0011 [#1] PREEMPT SMP DEBUG_PAGEALLOC <4>Modules linked in: af_iucv sunrpc qeth_l3 dm_multipath dm_mod qeth vmur ccwgroup <4>CPU: 0 Not tainted 2.6.30 #4 <4>Process iucv_sock_close (pid: 2486, task: 000000003aea4340, ksp: 000000003b75bc68) <4>Krnl PSW : 0704200180000000 000003e00168e23a (iucv_sock_kill+0x2e/0xcc [af_iucv]) <4> R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:0 CC:2 PM:0 EA:3 <4>Krnl GPRS: 0000000000000000 000000003b75c000 000000003edd37f0 0000000000000001 <4> 000003e00168ec62 000000003988d960 0000000000000000 000003e0016b0608 <4> 000000003fe81b20 000000003839bb58 00000000399977f0 000000003edd37f0 <4> 000003e00168b000 000003e00168f138 000000003b75bcd0 000000003b75bc98 <4>Krnl Code: 000003e00168e22a: c0c0ffffe6eb larl %r12,3e00168b000 <4> 000003e00168e230: b90400b2 lgr %r11,%r2 <4> 000003e00168e234: e3e0f0980024 stg %r14,152(%r15) <4> >000003e00168e23a: e310225e0090 llgc %r1,606(%r2) <4> 000003e00168e240: a7110001 tmll %r1,1 <4> 000003e00168e244: a7840007 brc 8,3e00168e252 <4> 000003e00168e248: d507d00023c8 clc 0(8,%r13),968(%r2) <4> 000003e00168e24e: a7840009 brc 8,3e00168e260 <4>Call Trace: <4>([<000003e0016b0608>] afiucv_dbf+0x0/0xfffffffffffdea20 [af_iucv]) <4> [<000003e00168ec6c>] iucv_sock_close+0x130/0x368 [af_iucv] <4> [<000003e00168ef02>] iucv_sock_release+0x5e/0xe4 [af_iucv] <4> [<0000000000438e6c>] sock_release+0x44/0x104 <4> [<0000000000438f5e>] sock_close+0x32/0x50 <4> [<0000000000207898>] __fput+0xf4/0x250 <4> [<00000000002038aa>] filp_close+0x7a/0xa8 <4> [<00000000002039ba>] SyS_close+0xe2/0x148 <4> [<0000000000117c8e>] sysc_noemu+0x10/0x16 <4> [<00000042ff8deeac>] 0x42ff8deeac Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Ursula Braun <ursula.braun@de.ibm.com> Signed-off-by: David S.

| * iucv: fix iucv_buffer_cpumask check when calling IUCV functionsHendrik Brueckner2009-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to calling IUCV functions, the DECLARE BUFFER function must have been called for at least one CPU to receive IUCV interrupts. With commit "iucv: establish reboot notifier" (6c005961), a check has been introduced to avoid calling IUCV functions if the current CPU does not have an interrupt buffer declared. Because one interrupt buffer is sufficient, change the condition to ensure that one interrupt buffer is available. In addition, checking the buffer on the current CPU creates a race with CPU up/down notifications: before checking the buffer, the IUCV function might be interrupted by an smp_call_function() that retrieves the interrupt buffer for the current CPU. When the IUCV function continues, the check fails and -EIO is returned. If a buffer is available on any other CPU, the IUCV function call must be invoked (instead of failing with -EIO).

Grandchildren always get the first tx queue, which would give wrong qdisc_root etc. results (e.g. for sch_htb as child of sch_prio). This patch fixes it by using parent's dev_queue for such grandchildren qdiscs. The select_queue method's return type is changed BTW.

The approach there is to call dev_close()/dev_open() whenever the device type is changed in order to remap the device IP multicast addresses to HW multicast addresses. This approach suffers from 2 drawbacks: *. It assumes tha the device is UP when calling dev_close(), or otherwise dev_close() has no affect. It is worth to mention that initscripts (Redhat) and sysconfig (Suse) doesn't act the same in this matter. *. dev_close() has other side affects, like deleting entries from the routing table, which might be unnecessary. The fix here is to directly remap the IP multicast addresses to HW multicast addresses for a bonding device that changes its type, and nothing else.
