* [S390] cio: fix sanity checks in ccwgroup driver.Sebastian Ott2009-03-261-4/+12
| | | | | | | | Some sanity checks in the ccw group driver test the output of container_of macros to be !NULL. Test the input parameters instead. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

* [S390] cio/crw: add/fix lockingHeiko Carstens2009-03-261-9/+23
| | | | | | | | | | | | | | | The crw_unregister_handler uses xchg + synchronize_sched when unregistering a crw_handler. This doesn't protect crw_collect_info to potentially jump to NULL since it has unlocked code like this: if (crw_handlers[i]) crw_handlers[i](NULL, NULL, 1); So add a mutex which protects the crw handler array for changes.

* [S390] cio: Use ccw_device_set_notoper().Cornelia Huck2009-03-261-1/+1
| | | | | | | | | | | Use ccw_device_set_notoper() (which also deletes the device timer and disables the subchannel) instead of simply setting the state to DEV_STATE_NOT_OPER in the generic not operational handling code. This prevents unexpected interrupts popping up for devices that are deemed not operational.

* [S390] cio: Try harder to disable subchannel.Cornelia Huck2009-03-262-9/+11
| | | | | | | | | | | | Acting upon the assumption that cio_disable_subchannel() is only called when we really want to disable the subchannel (a) remove the check for activity (it is already done in ccw_device_offline(), which is the place where it matters) (b) collect pending status via tsch() and ignore it (it can't matter anymore since the subchannel will be disabled).

* [S390] cio: Use unbind/bind instead of unregister/register.Cornelia Huck2009-03-263-23/+10
| | | | | | | | | | | | | The common I/O layer may encounter a situation where the device number of a ccw device has changed or a device driver doesn't want to keep a formerly disconnected device becoming operational again. Instead of using device_del()/ device_add() as now, we can just unbind the driver from the device and rebind it to get the desired effect (rebinding) with less overhead.

* [S390] Fix hypervisor detection for KVMChristian Borntraeger2009-03-264-10/+17
| | | | | | | | | | | | | | | | | | | | | | | | Currently we use the cpuid (via STIDP instruction) to recognize LPAR, z/VM and KVM. The architecture states, that bit 0-7 of STIDP returns all zero, and if STIDP is executed in a virtual machine, the VM operating system will replace bits 0-7 with FF. KVM should not use FE to distinguish z/VM from KVM for interested guests. The proper way to detect the hypervisor is the STSI (Store System Information) instruction, which return information about the hypervisors via function code 3, selector1=2, selector2=2. This patch changes the detection routine of Linux to use STSI instead of STIDP. This detection is earlier than bootmem, we have to use a static buffer. Since STSI expects a 4kb block (4kb aligned) this patch also changes the init.data alignment for s390. As this section will be freed during boot, this should be no problem. Patch is tested with LPAR, z/VM, KVM on LPAR, and KVM under z/VM. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

| | * nl80211: Check that function pointer != NULL before using itJouni Malinen2009-03-201-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NL80211_CMD_GET_MESH_PARAMS and NL80211_CMD_SET_MESH_PARAMS handlers did not verify whether a function pointer is NULL (not supported by the driver) before trying to call the function. The former nl80211 command is available for unprivileged users, too, so this can potentially allow normal users to kill networking (or worse..) if mac80211 is built without CONFIG_MAC80211_MESH=y.

| * smsc911x: reset last known duplex and carrier on openSteve Glendinning2009-03-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.
