2008-07-04pasemi_mac: Access iph->tot_len with correct endiannessRoland Dreier
iph->tot_len is stored in network byte order, so access it using ntohs(). This doesn't have any real world impact on pasemi_mac, since the device only exists as part of a big-endian system-on-chip, but fixing this gets rid of a sparse warning and avoids having a bad example in the tree.

2008-07-04Add missing skb->dev assignment in Frame Relay RX codeKrzysztof Halasa
Commit 4c13eb6657fe9ef7b4dc8f1a405c902e9e5234e0 ([ETH]: Make eth_type_trans set skb->dev like the other *_type_trans) removed skb->dev assignment from hdlc_fr.c:fr_rx(). Unfortunately it was also needed for cases other than eth_type_trans(). Adding it back.

2008-07-03USB: fix interrupt disabling for HCDs with shared interrupt handlersStefan Becker
USB: fix interrupt disabling for HCDs with shared interrupt handlers As has been discussed several times on LKML, IRQF_SHARED | IRQF_DISABLED doesn't work reliably, i.e. a shared interrupt handler CAN'T be certain to be called with interrupts disabled. Most USB HCD handlers use IRQF_DISABLED and therefore havoc can break out if they share their interrupt with a handler that doesn't use it. On my test machine the yenta_socket interrupt handler (no IRQF_DISABLED) was registered before ehci_hcd and one uhci_hcd instance. Therefore all usb_hcd_irq() invocations for ehci_hcd and for one uhci_hcd instance happened with interrupts enabled. That led to random lockups as USB core HCD functions that acquire the same spinlock could be called twice from interrupt handlers. This patch updates usb_hcd_irq() to always disable/restore interrupts. usb_add_hcd() will silently remove any IRQF_DISABLED requested from HCD code.

2008-07-03USB: ohci - record data toggle after unlinkDavid Brownell
This patch fixes a problem with OHCI where canceling bulk or interrupt URBs may lose track of the right data toggle. This seems to be a longstanding bug, possibly dating back to the Linux 2.4 kernel, which stayed hidden because (a) about half the time the data toggle bit was correct; (b) canceling such URBs is unusual; and (c) the few drivers which cancel these URBs either [1] do it only as part of shutting down, or [2] have fault recovery logic, which recovers. For those transfer types, the toggle is normally written back into the ED when each TD is retired. But canceling bypasses the mechanism used to retire TDs ... so on average, half the time the toggle bit will be invalid after cancelation. The fix is simple: the toggle state of any canceled TDs are propagated back to the ED in the finish_unlinks function. (Issue found by leonidv11@gmail.com ...)

2008-07-03USB: ehci - fix timer regressionDavid Brownell
This patch fixes a regression in the EHCI driver's TIMER_IO_WATCHDOG behavior. The patch "USB: EHCI: add separate IAA watchdog timer" changed how that timer is handled, so that short timeouts on the remaining timer (unfortunately, overloaded) would never be used. This takes a more direct approach, reorganizing the code slightly to be explicit about only the I/O watchdog role now being overridable. It also replaces a now-obsolete comment describing older timer behavior.

2008-07-02PCI: acpiphp: cleanup notify handler on all root bridgesAlex Chiang
During the development of the physical PCI slot patch series, Gary Hade kept on reporting strange oopses due to interactions between pci_slot and acpiphp. http://lkml.org/lkml/2007/11/28/319 find_root_bridges() unconditionally installs handle_hotplug_event_bridge() as an ACPI_SYSTEM_NOTIFY handler for all root bridges. However, during module cleanup, remove_bridge() will only remove the notify handler iff the root bridge had a hot-pluggable slot directly underneath. That is: root bridge -> hotplug slot But, if the topology looks like either of the following: root bridge -> non-hotplug slot root bridge -> p2p bridge -> hotplug slot Then we currently do not remove the notify handler from that root bridge. This can cause a kernel oops if we modprobe acpiphp later and it gets loaded somewhere else in memory. If the root bridge then receives a hotplug event, it will then attempt to call a stale, non-existent notify handler and we blow up. Much thanks goes to Gary Hade for his persistent debugging efforts.

2008-07-02PCI: Limit VPD read/write lengths for Broadcom 5706, 5708, 5709 rev.Benjamin Li
For Broadcom 5706, 5708, 5709 rev. A nics, any read beyond the VPD end tag will hang the device. This problem was initially observed when a vpd entry was created in sysfs ('/sys/bus/pci/devices/<id>/vpd'). A read to this sysfs entry will dump 32k of data. Reading a full 32k will cause an access beyond the VPD end tag causing the device to hang. Once the device is hung, the bnx2 driver will not be able to reset the device. We believe that it is legal to read beyond the end tag and therefore the solution is to limit the read/write length. A majority of this patch is from Matthew Wilcox who gave code for reworking the PCI vpd size information. A PCI quirk added for the Broadcom NIC's to limit the read/write's.

2008-07-01I2C: S3C2410: Add MODULE_ALIAS() for s3c2440 device.Ben Dooks
Add a MODULE_ALIAS() statement for the i2c-s3c2410 controller to ensure that it can be autoloaded on the S3C2440 systems that we support. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-07-01I2C: S3C2410: Fixup error codes returned rom a transfer.Ben Dooks
The driver should be returning -ENXIO for transfers that do not pass the initial address byte stage. Note, also small tidyups to the driver comments in the area. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-07-01I2C: S3C2410: Check ACK on byte transmissionBen Dooks
We should check for the reception of an ACK after transmitting each data byte. The address send has been correctly checking this, but the data write byte state should have also been checking for these failures. As part of the same fix, we remove the ACK checking from the receive path where it should not have been checking for an ACK which our hardware was sending.

2008-06-30hostap: fix sparse warningsPavel Roskin
Rewrite AID calculation in handle_pspoll() to avoid truncating bits. Make hostap_80211_header_parse() static, don't export it. Avoid shadowing variables. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-06-30hostap: don't report useless WDS frames by defaultPavel Roskin
DEBUG_EXTRA is reported to the kernel log by default, but DEBUG_EXTRA2 is not. Unrelated WDS frames pollute the log unnecessarily. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
