2011-04-04[S390] cio: prevent purging of CCW devices in the online statePeter Oberparleiter1-6/+18
The cio_ignore purge function is intended to only remove CCW devices which are in the offline state. There is a time frame after the purge function finished where a CCW device is scheduled for removal but still accessible. When the device is set online during this time frame, it may first appear online before it is then removed. Fix this by preventing that CCW devices can be set online while there is work (such as removal triggered by the purge function) for it pending. Also ensure that the purge function does not schedule devices for removal which are in the process of being set online.

2011-04-01usbnet: use eth%d name for known ethernet devicesArnd Bergmann10-12/+21
The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.

On a "really fragile" laptop I noticed a single i8042.c: i8042 controller selftest failed. (0x1 != 0x55) error in the log. But there's no reason to print this message at KERN_ERR level each time that loop fails, especially since the message telling about the overall selftest failure is printed at KERN_INFO level (on X86).

Without this parameter, sci_console_init is called during early console setup without any port being initialized, and the kernel crashes a little bit later when uart_set_options attemps to invoke set_termios on a port with an ops member equal to NULL. This patch just checks in sci_console_init that the port is properly initialized, and aborts the early console setup if it is not.

2011-03-30gpio/pca953x: fix error handling path in probe() callBen Dooks1-2/+3
If the device fails to respond, then the error path tries to remove an interrupt that never got registered, which causes an backtrace from the interrupt handling code. Fix this by ensuring that the cleanup path has two labels and use the correct path as needed. fixes the following error: WARNING: at kernel/irq/manage.c:908 __free_irq+0x80/0x160() Trying to free already-free IRQ 0 Signed-off-by: Ben Dooks <[email protected]> Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Grant Likely <[email protected]>
2011-03-30connector: convert to synchronous netlink message processingPatrick McHardy2-76/+29
Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms) and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct netlink_skb_parms) removed some members from struct netlink_skb_parms that depend on the current context, all netlink users are now required to do synchronous message processing. connector however queues received messages and processes them in a work queue, which is not valid anymore. This patch converts connector to do synchronous message processing by invoking the registered callback handler directly from the netlink receive function. In order to avoid invoking the callback with connector locks held, a reference count is added to struct cn_callback_entry, the reference is taken when finding a matching callback entry on the device's queue_list and released after the callback handler has been invoked.

2011-03-30atm/solos-pci: Don't flap VCs when carrier state changesPhilip A. Prindeville1-25/+1
Don't flap VCs when carrier state changes; higher-level protocols can detect loss of connectivity and act accordingly. This is more consistent with how other network interfaces work. We no longer use release_vccs() so we can delete it. release_vccs() was duplicated from net/atm/common.c; make the corresponding function exported, since other code duplicates it and could leverage it if it were public.
