2006-07-12[PATCH] USB: Add one VID/PID to ftdi_sioColin Leroy
This patch adds the Testo USB interface to the list of devices recognized by the ftdi_sio module. This device is based on a FT232BL chip, and is used as an interface to get data from digital sensors (thermometer, etc).

I just got a "ZyXEL Prestige USB Adapter" that is actually RTL8150 adapter. Here is the relevant /proc/bus/usb/devices output (after adding the vendor/product IDs to the driver): T: Bus=01 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#=119 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0586 ProdID=401a Rev= 1.00 S: Manufacturer=ZyXEL S: Product=Prestige USB Adapter S: SerialNumber=1027 C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=120mA I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.)

The device has absolutely no identifying marks on the outside for model type, just a serial number, and I can't find anything on ZyXEL's website, so I called the product ID PRODUCT_ID_PRESTIGE to match the product string.

2006-07-12[PATCH] USB: ipw.c driver fixBart Oldeman
The below patch fixes the ipw module in kernel 2.6.17 for me; without this change it simply does not work at all (all but the first writes are refused because write_urb_busy is always 1). This problem was there in 2.6.15 as well, but at that point I used the (updated) ipw.c, version 0.4, from http://www.neology.co.za/products/opensource/ipwireless/ which no longer compiles with 2.6.17. It can be made to after a few changes but obviously it's easier if the built-in ipw driver works instead of having to download one from the neology site.

2006-07-12[PATCH] USB: ipaq.c timing parametersFrank Gevaerts
Adds configurable waiting periods to the ipaq connection code. These are not needed when the pocketpc device is running normally when plugged in, but they need extra delays if they are physically connected while rebooting. There are two parameters : * initial_wait : this is the delay before the driver attemts to start the connection. This is needed because the pocktpc device takes much longer to boot if the driver starts sending control packets too soon. * connect_retries : this is the number of times the control urb is retried before finally giving up. The patch also adds a 1 second delay between retries. I'm not sure if the cases where this patch is useful are general enough to include this in the kernel.

2006-07-12[PATCH] USB: ehci: fix bogus alteration of a local variableDavid Brownell
In a rare and all-but-unused path, the EHCI driver could reuse a variable in a way that'd make trouble. Specifically, if the first root hub port gets an overcurrent event (rare) during a remote wakeup scenario (all but unused in today's Linux, except for folk working with suspend-to-RAM and similar sleep states), that would look like a fatal error which would shut down the controller. Fix by not reusing that variable.

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.)

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.

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>

When found, it is obvious. nfds calculated when allocating fdsets is rewritten by calculation of size of fdtable, and when we are unlucky, we try to free fdsets of wrong size. Found due to OpenVZ resource management (User Beancounters).

2006-07-12[PATCH] Fix prctl privilege escalation and suid_dumpable (CVE-2006-2451)Marcel Holtmann
Based on a patch from Ernie Petrides During security research, Red Hat discovered a behavioral flaw in core dump handling. A local user could create a program that would cause a core file to be dumped into a directory they would not normally have permissions to write to. This could lead to a denial of service (disk consumption), or allow the local user to gain root privileges. The prctl() system call should never allow to set "dumpable" to the value 2. Especially not for non-privileged users. This can be split into three cases: 1) running as root -- then core dumps will already be done as root, and so prctl(PR_SET_DUMPABLE, 2) is not useful 2) running as non-root w/setuid-to-root -- this is the debatable case 3) running as non-root w/setuid-to-non-root -- then you definitely do NOT want "dumpable" to get set to 2 because you have the privilege escalation vulnerability With case #2, the only potential usefulness is for a program that has designed to run with higher privilege (than the user invoking it) that wants to be able to create root-owned root-validated core dumps. This might be useful as a debugging aid, but would only be safe if the program had done a chdir() to a safe directory. There is no benefit to a production setuid-to-root utility, because it shouldn't be dumping core in the first place. If this is true, then the same debugging aid could also be accomplished with the "suid_dumpable" sysctl.
