| * xhci: Fix command ring replay after resume.Sarah Sharp2010-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Andiry's xHCI bus suspend patch introduced the possibly of a host controller replaying old commands on the command ring, if the host successfully restores the registers after a resume. After a resume from suspend, the xHCI driver must restore the registers, including the command ring pointer. I had suggested that Andiry set the command ring pointer to the current command ring dequeue pointer, so that the driver wouldn't have to zero the command ring. Unfortunately, setting the command ring pointer to the current dequeue pointer won't work because the register assumes the pointer is 64-byte aligned, and TRBs on the command ring are 16-byte aligned. The lower seven bits will always be masked off, leading to the written pointer being up to 3 TRBs behind the intended pointer. Here's a log excerpt. On init, the xHCI driver places a vendor-specific command on the command ring: [ 215.750958] xhci_hcd 0000:01:00.0: Vendor specific event TRB type = 48 [ 215.750960] xhci_hcd 0000:01:00.0: NEC firmware version 30.25 [ 215.750962] xhci_hcd 0000:01:00.0: Command ring deq = 0x3781e010 (DMA) When we resume, the command ring dequeue pointer to be written should have been 0x3781e010. Instead, it's 0x3781e000: [ 235.557846] xhci_hcd 0000:01:00.0: // Setting command ring address to 0x3781e001 [ 235.557848] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 64'hffffc900100bc038, 64'h3781e001, 4'hf); [ 235.557850] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 32'hffffc900100bc020, 32'h204, 4'hf); [ 235.557866] usb usb9: root hub lost power or was reset (I can't see the results of this bug because the xHCI restore always fails on this box, and the xHCI driver re-allocates everything.) The fix is to zero the command ring and put the software and hardware enqueue and dequeue pointer back to the beginning of the ring. We do this before the system suspends, to be paranoid and prevent the BIOS from starting the host without clearing the command ring pointer, which might cause the host to muck with stale memory. (The pointer isn't required to be in the suspend power well, but it could be.) The command ring pointer is set again after the host resumes.

| * xHCI: fix wMaxPacketSize maskAndiry Xu2010-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB2.0 spec 9.6.6 says: For all endpoints, bit 10..0 specify the maximum packet size(in bytes). So the wMaxPacketSize mask should be 0x7ff rather than 0x3ff. This patch should be queued for the stable tree. The bug in xhci_endpoint_init() was present as far back as 2.6.31, and the bug in xhci_get_max_esit_payload() was present when the function was introduced in 2.6.34.

| * xhci: Remove excessive printks with shared IRQs.Sarah Sharp2010-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the xHCI host controller shares an interrupt line with another device, the xHCI driver needs to check if the interrupt was generated by its hardware. Unfortunately, the user will see a ton of "Spurious interrupt." lines if the other hardware interrupts often. Lawrence found his dmesg output cluttered with this output when the xHCI host shared an interrupt with his i915 hardware. Remove the warning, as sharing an interrupt is a normal thing. This should be applied to the 2.6.36 stable tree. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Reported-by: Lawrence Rust <lvr@softsystem.co.uk> Cc: stable@kernel.org

This removes the BKL from the various open functions that do not need it, or only use it to protect an open count. The zoran driver is nontrivial in this regard, so I introduce a new mutex that locks both the open/release and the ioctl functions. Someone with access to the hardware can probably improve that by using the existing lock in all cases. Finally, all drivers that still use the locked version of the ioctl function now get called under a new mutex instead of the BKL.

The intent is that when the interface comes back up the address will be usable again. However, this doesn't actually work, because the system stops listening on the corresponding solicited-node multicast address, so the address cannot respond to neighbor solicitations and thus receive traffic. Also, the code notifies the rest of the system that the address is being deleted (e.g, RTM_DELADDR), even though it is not. Fix it so that none of this state is updated if the address is being kept on the interface. Tested: Added a statically configured IPv6 address to an interface, started ping, brought link down, brought link up again. When link came up ping kept on going and "ip -6 maddr" showed that the host was still subscribed to there Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S.

Just skip this new code block if sock_owned_by_user() is true and eliminate the now superfluous sock_owned_by_user() code block contained within.

On parsing malformed X.25 facilities, decrementing the remaining length may cause it to underflow. Since the length is an unsigned integer, this will result in the loop continuing until the kernel crashes. This patch adds checks to ensure decrementing the remaining length does not cause it to wrap around. Signed-off-by: Dan Rosenberg <drosenberg@vsecurity.com> Signed-off-by: David S.

However, if vlan offloading is disabled or otherwise not used, the protocol field will be ETH_P_8021Q, not the actual protocol. This will cause the offloading to be not performed correctly, even though the hardware is capable of looking inside vlan tags. Instead, look inside the header if necessary to determine the correct protocol type. To some extent this fixes a regression from 2.6.36 because it was previously not possible to disable vlan offloading and this error case was not exposed.
