2011-02-17USB: Reset USB 3.0 devices on (re)discoveryLuben Tuikov1-11/+7
If the device isn't reset, the XHCI HCD sends SET ADDRESS to address 0 while the device is already in Addressed state, and the request is dropped on the floor as it is addressed to the default address. This sequence of events, which this patch fixes looks like this: usb_reset_and_verify_device() hub_port_init() hub_set_address() SET_ADDRESS to 0 with 1 usb_get_device_descriptor(udev, 8) usb_get_device_descriptor(udev, 18) descriptors_changed() --> goto re_enumerate: hub_port_logical_disconnect() kick_khubd() And then: hub_events() hub_port_connect_change() usb_disconnect() usb_disable_device() new device struct sets device state to Powered choose_address() hub_port_init() <-- no reset, but SET ADDRESS to 0 with 1, timeout! The solution is to always reset the device in hub_port_init() to put it in a known state.

2011-02-17USB: Add quirk for Samsung Android phone modemMaciej Szmigiero1-0/+4
My Galaxy Spica needs this quirk when in modem mode, otherwise it causes endless USB bus resets and is unusable in this mode. Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500 for the modem part. That's why in addition to this patch the visor driver must be prevented from binding to SPH-I500 ID, so ACM driver can do that.

2011-02-17USB: Add Samsung SGH-I500/Android modem ID switch to visor driverMaciej Szmigiero1-0/+12
[USB]Add Samsung SGH-I500/Android modem ID switch to visor driver Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the modem part of some of their Android phones. At least Galaxy Spica is affected. This modem needs ACM driver and does not work with visor driver which binds the conflicting ID for SGH-I500. Because SGH-I500 is pretty an old hardware its best to add switch to visor driver in cause somebody still wants to use that phone with Linux. Note that this is needed only when using the Android phone as modem, not in USB storage or ADB mode.

2011-02-17usb: musb: omap2430: fix kernel panic on rebootJohan Hovold1-0/+1
Cancel idle timer in musb_platform_exit. The idle timer could trigger after clock had been disabled leading to kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37. The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled later, and only if compiled as a module, and the offending memory access has moved) but the timer should be cancelled nonetheless.

2011-02-17netfilter: tproxy: do not assign timewait sockets to skb->skFlorian Westphal4-30/+44
Assigning a socket in timewait state to skb->sk can trigger kernel oops, e.g. in nfnetlink_log, which does: if (skb->sk) { read_lock_bh(&skb->sk->sk_callback_lock); if (skb->sk->sk_socket && skb->sk->sk_socket->file) ... in the timewait case, accessing sk->sk_callback_lock and sk->sk_socket is invalid. Either all of these spots will need to add a test for sk->sk_state != TCP_TIME_WAIT, or xt_TPROXY must not assign a timewait socket to skb->sk. This does the latter. If a TW socket is found, assign the tproxy nfmark, but skip the skb->sk assignment, thus mimicking behaviour of a '-m socket .. -j MARK/ACCEPT' re-routing rule. The 'SYN to TW socket' case is left unchanged -- we try to redirect to the listener socket.

The code finds, the '%' sign in an ipv6 address and copies that to a buffer allocated on the stack. It then ignores that buffer, and passes 'pct' to simple_strtoul(), which doesn't work right because we're comparing 'endp' against a completely different string. Fix it by passing the correct pointer. While we're at it, this is a good candidate for conversion to strict_strtoul as well.

This reverts commit 75f1dc0d076d ("block: check bdev_read_only() from blkdev_get()"). That commit added stricter checking to make sure devices that were being used read-only were actually opened in that mode. It turns out that the change breaks a bunch of kernel code that opens block devices. Affected systems include dm, md, and the loop device. Because strict checking for read-only opens of block devices was not done before this, the code that opens the devices was opening them read-write even if they were being used read-only. Auditing all that code will take time, and new userspace packages for dm, mdadm, etc. will also be required.

2011-02-16Btrfs: allow balance to explicitly allocate chunks as it relocatesChris Mason3-1/+21
Btrfs device shrinking and balancing ends up reallocating all the blocks in order to allow COW to move them to new destinations. It is somewhat awkward in terms of ENOSPC because most of the enospc code is built around the idea that some operation on a reference counted tree triggers allocations in the non-reference counted trees. This commit changes the balancing code to deal with enospc by trying to allocate a new chunk. If that allocation succeeds, we go ahead and retry whatever failed due to enospc.

2011-02-16workqueue: make sure MAYDAY_INITIAL_TIMEOUT is at least 2 jiffies longTejun Heo1-1/+3
MAYDAY_INITIAL_TIMEOUT is defined as HZ / 100 and depending on configuration may end up 0 or 1. Even when it's 1, depending on when the mayday timer is added in the current jiffy interval, it may expire way before a jiffy has passed. Make sure MAYDAY_INITIAL_TIMEOUT is at least two to guarantee that at least a full jiffy has passed before calling rescuers.
