* eCryptfs: Allocate a variable number of pages for file headersTyler Hicks2009-03-231-13/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 8faece5f906725c10e7a1f6caf84452abadbdc7b upstream. When allocating the memory used to store the eCryptfs header contents, a single, zeroed page was being allocated with get_zeroed_page(). However, the size of an eCryptfs header is either PAGE_CACHE_SIZE or ECRYPTFS_MINIMUM_HEADER_EXTENT_SIZE (8192), whichever is larger, and is stored in the file's private_data->crypt_stat->num_header_bytes_at_front field. ecryptfs_write_metadata_to_contents() was using num_header_bytes_at_front to decide how many bytes should be written to the lower filesystem for the file header. Unfortunately, at least 8K was being written from the page, despite the chance of the single, zeroed page being smaller than 8K. This resulted in random areas of kernel memory being written between the 0x1000 and 0x1FFF bytes offsets in the eCryptfs file headers if PAGE_SIZE was 4K. This patch allocates a variable number of pages, calculated with num_header_bytes_at_front, and passes the number of allocated pages along to ecryptfs_write_metadata_to_contents(). Thanks to Florian Streibelt for reporting the data leak and working with me to find the problem. 2.6.28 is the only kernel release with this vulnerability.

* menu: fix embedded menu snafuRandy Dunlap2009-03-231-15/+15
| | | | | | | | | | | | | | | | commit b943c460ff8556a193b28e2145b513f8b978e869 upstream. The COMPAT_BRK kconfig symbol does not depend on EMBEDDED, but it is in the midst of the EMBEDDED menu symbols, so it mucks up the EMBEDDED menu. Fix by moving it to just after all of the EMBEDDED menu symbols. Also, ANON_INODES has a similar problem, so move it to just above the EMBEDDED menu items since it is used in the EMBEDDED menu.

* drm/i915: Don't allow objects to get bound while VT switched.Eric Anholt2009-03-231-6/+9
| | | | | | | | | | | | | | | | commit 9bb2d6f94aeb9a185d69aedbd19421b6da4e3309 upstream. This avoids a BUG_ON in the enter_vt path due to objects being in the GTT when we shouldn't have ever let them be (as we're not supposed to touch the device during that time). This was triggered by a change in the 2D driver to use the GTT mapping of objects after pinning them to improve software fallback performance.

* drm/i915: set vblank enabled flag correctly across IRQ install/uninstallJesse Barnes2009-03-231-3/+15
| | | | | | | | | | | | | | | | | | | | | | | commit dc1336ff4fe08ae7cfe8301bfd7f0b2cfd31d20a upstream. In the absence of kernel mode setting, many drivers disable IRQs across VT switch. The core DRM vblank code is missing a check for this case however; even after IRQ disable, the vblank code will still have the vblank_enabled flag set, so unless we track the fact that they're disabled at IRQ uninstall time, when we VT switch back in we won't actually re-enable them, which means any apps waiting on vblank before the switch will hang. This patch does that and also adds a sanity check to the wait condition to look for the irq_enabled flag in general, as well as adding a wakeup to the IRQ uninstall path. Fixes fdo bug #18879 with compiz hangs at VT switch.

* USB: EHCI: Fix isochronous URB leakKarsten Wiese2009-03-231-6/+4
| | | | | | | | | | | | | | | | | | commit 508db8c954d55ed30f870d2c24d741ba6269d13c upstream. ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing isochronous URB's kref.counts incrementing once per usb_submit_urb() call. The culprit is *usb being set to NULL when usb_put_urb() is called after URB is given back. Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb() nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd. Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a stream finishes.

* USB: EHCI: expedite unlinks when the root hub is suspendedAlan Stern2009-03-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | commit 391016f6e2fe3b9979b4c6880a76e5e434d6947c upstream. This patch (as1225) fixes a bug in ehci-hcd. The condition for whether unlinked QHs can become IDLE should not be that the controller is halted, but rather that the controller isn't running. In other words when the root hub is suspended, the hardware doesn't own any QHs. This fixes a problem that can show up during hibernation: If a QH is only partially unlinked when the root hub is frozen, then when the root hub is thawed the QH won't be in the IDLE state. As a result it can't be used properly for new URB submissions.

* USB: usbfs: keep async URBs until the device file is closedAlan Stern2009-03-231-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | commit 6ff10464096540e14d7575a72c50d0316d003714 upstream. The usbfs driver manages a list of completed asynchronous URBs. But it is too eager to free the entries on this list: destroy_async() gets called whenever an interface is unbound or a device is removed, and it deallocates the outstanding struct async entries for all URBs on that interface or device. This is wrong; the user program should be able to reap an URB any time after it has completed, regardless of whether or not the interface is still bound or the device is still present. This patch (as1222) moves the code for deallocating the completed list entries from destroy_async() to usbdev_release(). The outstanding entries won't be freed until the user program has closed the device file, thereby eliminating any possibility that the remaining URBs might still be reaped. This fixes a bug in which a program can hang in the USBDEVFS_REAPURB ioctl when the device is unplugged.

Analog support for HVR-1250 has not been completed, but does exist for the HVR-1800. Since both cards use the same driver, it tries to create the analog dev for both devices, which is not possible. This causes a NULL error to show up in video_open and mpeg_open. -Mark Iterations through the cx23885_devlist must check for NULL pointers as some supported devices only have DVB support at the moment.

* ata_piix: add workaround for Samsung DB-P70Tejun Heo2009-03-231-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | commit e9c1670c2a14ef9cc20d86b24b829f3947aad34e upstream. Samsung DB-P70 somehow botched the first ICH9 SATA port. The board doesn't expose the first port but somehow SStatus reports link online while failing SRST protocol leading to repeated probe failures and thus long boot delay. Because the BIOS doesn't carry any identifying DMI information, the port can't be blacklisted safely. Fortunately, the controller does have subsystem vendor and ID set. It's unclear whether the subsystem IDs are used only for the board but it can be safely worked around by disabling SIDPR access and just using SRST works around the problem. Even when the workaround is triggered on an unaffected board the only side effect will be missing SCR access.

* dm crypt: fix kcryptd_async_done parameterHuang Ying2009-03-231-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | commit b2174eebd1fadb76454dad09a1dacbc17081e6b0 upstream. In the async encryption-complete function (kcryptd_async_done), the crypto_async_request passed in may be different from the one passed to crypto_ablkcipher_encrypt/decrypt. Only crypto_async_request->data is guaranteed to be same as the one passed in. The current kcryptd_async_done uses the passed-in crypto_async_request directly which may cause the AES-NI-based AES algorithm implementation to panic. This patch fixes this bug by only using crypto_async_request->data, which points to dm_crypt_request, the crypto_async_request passed in. The original data (convert_context) is gotten from dm_crypt_request.

| | | | | | | | | | | | | | | | | | | | | commit bc0fd67feba2e0770aad85393500ba77c6489f1c upstream. When renaming a mapped device validate the length of the new name. The rename ioctl accepted any correctly-terminated string enclosed within the data passed from userspace. The other ioctls enforce a size limit of DM_NAME_LEN. If the name is changed and becomes longer than that, the device can no longer be addressed by name. Fix it by properly checking for device name length (including terminating zero).

* eventfd: remove fput() call from possible IRQ contextDavide Libenzi2009-03-231-10/+27

Myself, like Eric, wasn't able to reproduce an fput() call from IRQ context, but Jeff said he was able to, with the attached test program. Independently from this, the bug is conceptually there, so we might be better off fixing it. This patch adds an optimization similar to the one we already do on ->ki_filp, on ->ki_eventfd. Playing with ->f_count directly is not pretty in general, but the alternative here would be to add a brand new delayed fput() infrastructure, that I'm not sure is worth it.
