When I viewed drivers/video/modedb.c, I noticed a very old typo already contained in 2.6.0. This typo remained unheeded at least 5 years. Clear evidence of its importance. ;) Acked-by:

Use the newly introduced pci_ioremap_bar() function in drivers/video. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks. Signed-off-by:

Provide a static debounce configuration mechanism for twl4030 GPIOs, replacing the previous dynamic one. The single user of that mechanism was for MMC card detect debouncing. Boards can provide a bitmask saying which GPIOs to debounce (30 msec). It's always enabled for pins with the MMC card-detect/VMMCx link active, so most boards won't need to set the debounce mask. This is a net code shrink, including runtime footprint. Signed-off-by:

rtc is clearly does not satisfy IS_ERR at the point where it is tested, so I have changed the test to consider the just initialized rtc->rtc_dev. The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match exists@ expression x, E; identifier fld; position p1,p2; @@ ( x = E; | x = E | x@p1->fld ... when != x = E IS_ERR(x@p2) ... when any ) @other_match exists@ expression match.x, E1, E2; position match.p1,match.p2; @@ x = E1 ... when != x = E2 when != x@p1 x@p2 @ script:python depends on !other_match@ p1 << match.p1; p2 << match.p2; @@ print "* file %s dereference %s test %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by:

With PXA27x and above, a new RTC hardware block was added in addition to the legacy one which is also found on the SA1100 SOC family. This second RTC block is called "wristwatch" and "periodic interrupt" and works independently from the other RTC block. The driver offers provides : - a 1Hz ticking clock - a periodic alarm, in the 1Hz to 1000Hz range - a one shot alarm Signed-off-by:

This patch fixes a bunch of irq checking misuses. Most drivers were getting irq via platform_get_irq(), which returns -ENXIO or r->start. rtc-cmos.c is special. It is using PNP and platform bindings. Hopefully nobody is using PNP IRQ 0 for RTC. So the changes should be safe. rtc-sh.c is using platform_get_irq, but was storing a result into an unsigned type, then was checking for < 0. This is fixed now. Signed-off-by:

- the type assigned at mount when no type is given is changed from 0 to AUTOFS_TYPE_INDIRECT. This was done because 0 and AUTOFS_TYPE_INDIRECT were being treated implicitly as the same type. - previously, an offset mount had it's type set to AUTOFS_TYPE_DIRECT|AUTOFS_TYPE_OFFSET but the mount control re-implementation needs to be able distinguish all three types. So this was changed to make the type setting explicit. - a type AUTOFS_TYPE_ANY was added for use by the re-implementation when checking if a given path is a mountpoint. It's not really a type as we use this to ask if a given path is a mountpoint in the autofs_dev_ioctl_ismountpoint() function. - functions to set and test the autofs mount types have been added to improve readability and make the type usage explicit. - the mount type is used from user space for the mount control re-implementtion so, for consistency, all the definitions have been moved to the user space include file include/linux/auto_fs4.h.

Enable mount-wide filename encryption by providing the Filename Encryption Key (FNEK) signature as a mount option. Note that the ecryptfs-utils userspace package versions 61 or later support this option. When mounting with ecryptfs-utils version 61 or later, the mount helper will detect the availability of the passphrase-based filename encryption in the kernel (via the eCryptfs sysfs handle) and query the user interactively as to whether or not he wants to enable the feature for the mount. If the user enables filename encryption, the mount helper will then prompt for the FNEK signature that the user wishes to use, suggesting by default the signature for the mount passphrase that the user has already entered for encrypting the file contents. When not using the mount helper, the user can specify the signature for the passphrase key with the ecryptfs_fnek_sig= mount option. This key must be available in the user's keyring. The mount helper usually takes care of this step. If, however, the user is not mounting with the mount helper, then he will need to enter the passphrase key into his keyring with some other utility prior to mounting, such as ecryptfs-manager.

Michael Halcrow authored
This patchset implements filename encryption via a passphrase-derived mount-wide Filename Encryption Key (FNEK) specified as a mount parameter. Each encrypted filename has a fixed prefix indicating that eCryptfs should try to decrypt the filename. When eCryptfs encounters this prefix, it decodes the filename into a tag 70 packet and then decrypts the packet contents using the FNEK, setting the filename to the decrypted filename. Both unencrypted and encrypted filenames can reside in the same lower filesystem. Because filename encryption expands the length of the filename during the encoding stage, eCryptfs will not properly handle filenames that are already near the maximum filename length. In the present implementation, eCryptfs must be able to produce a match against the lower encrypted and encoded filename representation when given a plaintext filename. Therefore, two files having the same plaintext name will encrypt and encode into the same lower filename if they are both encrypted using the same FNEK. This can be changed by finding a way to replace the prepended bytes in the blocked-aligned filename with random characters; they are hashes of the FNEK right now, so that it is possible to deterministically map from a plaintext filename to an encrypted and encoded filename in the lower filesystem. An implementation using random characters will have to decode and decrypt every single directory entry in any given directory any time an event occurs wherein the VFS needs to determine whether a particular file exists in the lower directory and the decrypted and decoded filenames have not yet been extracted for that directory. Thanks to Tyler Hicks and David Kleikamp for assistance in the development of this patchset. This patch: A tag 70 packet contains a filename encrypted with a Filename Encryption Key (FNEK). This patch implements functions for writing and parsing tag 70 packets. This patch also adds definitions and extends structures to support filename encryption. Signed-off-by:

Remove called_from argument from kprobes which had been used for preventing self-refering of kernel module. However, since we don't keep module's refcount after registering kprobe any more, there is no reason to check that. This patch also simplifies registering/unregistering functions because we don't need to use __builtin_return_address(0) which was passed to called_from. [ananth@in.ibm.com: build fix] Signed-off-by:

Allows kprobes to probe __exit routine. This adds flags member to struct kprobe. When module is freed(kprobes hooks module_notifier to get this event), kprobes which probe the functions in that module are set to "Gone" flag to the flags member. These "Gone" probes are never be enabled. Users can check the GONE flag through debugfs. This also removes mod_refcounted, because we couldn't free a module if kprobe incremented the refcount of that module.
