2006-07-12[PATCH] USB serial ftdi_sio: Prevent userspace DoSIan Abbott
This patch limits the amount of outstanding 'write' data that can be queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents) that use up all the system memory by writing lots of data to the serial port. The original patch was by Guillaume Autran, who in turn based it on the same mechanism implemented in the 'visor' driver. I (Ian Abbott) re-targeted the patch to the latest sources, fixed a couple of errors, renamed his new structure members, and updated the implementations of the 'write_room' and 'chars_in_buffer' methods to take account of the number of outstanding 'write' bytes. It seems to work fine, though at low baud rates it is still possible to queue up an amount of data that takes an age to shift (a job for another day!).

2006-07-12[PATCH] USB serial visor: fix race in open/closeIan Abbott
The anti user-DoS mechanism in the USB serial 'visor' driver can fail in the following way: visor_open: priv->outstanding_urbs = 0 visor_write: ++priv->outstanding_urbs visor_close: visor_open: priv->outstanding_urbs = 0 visor_write_bulk_callback: --priv->outstanding_urbs So priv->outstanding_urbs ends up as (unsigned long)(-1). Not good! I haven't seen this happen with the visor driver as I don't have the hardware, but I have seen it while testing a patch to implement the same functionality in the ftdi_sio driver (patch not yet submitted). The fix is pretty simple: don't reinitialize outstanding_urbs in visor_open. (Again, I haven't tested the fix in visor, but I have tested it in ftdi_sio.)

2006-07-12[PATCH] USB: au1200: EHCI and OHCI fixesDaniel Mack
I received an DBAU1200 eval kit from AMD a few days ago and tried to enable the USB2 port, but the current linux-2.6 GIT did not even compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and CONFIG_USB_OHCI set. Furthermore, in ehci-hcd.c, platform_driver_register() was called with an improper argument of type 'struct device_driver *' which of course ended up in a kernel oops. How could that ever have worked on your machines? Anyway, here's a trivial patch that makes the USB subsystem working on my board for both OHCI and EHCI.

2006-07-12[PATCH] ide: fix Jmicron supportAlan Cox
Prior to 2.6.18rc1 you could install with devices on a JMicron chipset using the "all-generic-ide" option. As of this kernel the AHCI driver grabs the controller and rams it into AHCI mode losing the PATA ports and making CD drives and the like vanish. The all-generic-ide option fails because the AHCI driver grabbed the PCI device and reconfigured it. To fix this three things are needed. #1 We must put the chip into dual function mode #2 The AHCI driver must grab only function 0 (already in your rc1 tree) #3 Something must grab the PATA ports The attached patch is the minimal risk edition of this. It puts the chip into dual function mode so that AHCI will grab the SATA ports without losing the PATA ports. To keep the risk as low as possible the third patch adds the PCI identifiers for the PATA port and the FN check to the ide-generic driver. There is a more featured jmicron driver on its way but that adds risk and the ide-generic support is sufficient to install and run a system. The actual chip setup done by the quirk is the precise setup recommended by the vendor. (The JMB368 appears only in the ide-generic entry as it has no AHCI so does not need the quirk) Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-12Add PIIX4 APCI quirk for the 440MX chipset tooLinus Torvalds
This is confirmed to fix a hang due to PCI resource conflicts with setting up the Cardbus bridge on old laptops with the 440MX chipsets. Original report by Alessio Sangalli, lspci debugging help by Pekka Enberg, and trial patch suggested by Daniel Ritz: "From the docs available i would _guess_ this thing is really similar to the 82443BX/82371AB combination. at least the SMBus base address register is hidden at the very same place (32bit at 0x90 in function 3 of the "south" brigde)" The dang thing is largely undocumented, but the patch was corroborated by Asit Mallick: "I am trying to find the register information. 440MX is an integration of 440BX north-bridge without AGP and PIIX4E (82371EB). PIIX4 quirk should cover the ACPI and SMBus related I/O registers." and verified to fix the problem by Alessio.

2006-07-12[S390] path grouping and path verifications fixes.Cornelia Huck
1. Multipath devices for which SetPGID is not supported are not handled well. Use NOP ccws for path verification (sans path grouping) when SetPGID is not supported. 2. Check for PGIDs already set with SensePGID on _all_ paths (not just the first one) and try to find a common one. Moan if no common PGID can be found (and use NOP verification). If no PGIDs have been set, use the css global PGID (as before). (Rationale: SetPGID will get a command reject if the PGID it tries to set does not match the already set PGID.) 3. Immediately before reboot, issue RESET CHANNEL PATH (rcp) on all chpids. This will remove the old PGIDs. rcp will generate solicited CRWs which can be savely ignored by the machine check handler (all other actions create unsolicited CRWs).

2006-07-10[PATCH] snsc: switch from force_sig to kill_procChristoph Hellwig
Currently the snsc driver uses force_sig to send init a SIGPWR when the system overheats. This patch switches it to kill_proc instead which has the following advantages: (1) gets rid of one of the last remaining tasklist_lock users in modular code (2) simplifies the snsc code significantly The downside is that an init implementation could in theory block SIGPWR and it would not get delivered. The sysvinit code used by all major distributions doesn't do this and blocking this signal in init would be a rather stupid thing to do.

2006-07-10[PATCH] make valid_mmap_phys_addr_range() take a pfnLennert Buytenhek
Newer ARMs have a 40 bit physical address space, but mapping physical memory above 4G needs a special page table format which we (currently?) do not use for userspace mappings, so what happens instead is that mapping an address >= 4G will happily discard the upper bits and wrap. There is a valid_mmap_phys_addr_range() arch hook where we could check for >= 4G addresses and deny the mapping, but this hook takes an unsigned long address: static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size); And drivers/char/mem.c:mmap_mem() calls it like this: static int mmap_mem(struct file * file, struct vm_area_struct * vma) { size_t size = vma->vm_end - vma->vm_start; if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size)) So that's not much help either.

2006-07-10[PATCH] Fix and enable EDAC sysfs operationDoug Thompson
When EDAC was first introduced into the kernel it had a sysfs interface, but due to some problems it was disabled in 2.6.16 and remained disabled in 2.6.17. With feedback, several of the control and attribute files of that interface had some good constructive feedback. PCI Blacklist/Whitelist was a major set which has design issues and it has been removed in this patch. Instead of storing PCI broken parity status in EDAC, it has been moved to the pci_dev structure itself by a previous PCI patch. A future patch will enable that feature in EDAC by utilizing the pci_dev info. The sysfs is now enabled in this patch, with a minimal set of control and attribute files for examining EDAC state and for enabling/disabling the memory and PCI operations. The Documentation for EDAC has also been updated to reflect the new state of EDAC operation.

2006-07-10[PATCH] s390: move var declarations behind ifdefSerge E. Hallyn
Two variables in drivers/s390/net/qeth_main.c:qeth_send_packet() are only used if CONFIG_QETH_PERF_STATS. Move their definition under the same ifdef to remove compiler warning.
