The uevent consists of additional environment data containing the message prefix ("APP"), message sender, and message content. udev rules can be used to trigger application specific actions through matching the content or sender of the special message.

f8d4f61 | Eric W. Biederman | 13 February 2010, 03:22:23 UTC | sysfs: Serialize updates to the vfs inode The vfs depends upon filesystem methods to update the vfs inode. Sysfs adds to the normal number of places where the vfs inode is updated by also updatng the vfs inode in sysfs_refresh_inode. Typically the inode mutex is used to serialize updates to the vfs inode, but grabbing the inode mutex in sysfs_permission and sysfs_getattr causes deadlocks, because sometimes the vfs calls those operations with the inode mutex held. Therefore sysfs can not use the inode mutex to serial updates to the vfs inode. The sysfs_mutex is acquired in all of the routines where sysfs updates the vfs inode, and with a small change we can consistently protext sysfs vfs inode updates with the sysfs_mutex. To protect the sysfs vfs inode updates with the sysfs_mutex simply requires extending the scope of sysfs_mutex in sysfs_setattr over inode_setattr, and over inode_change_ok (so we have an unchanging inode when we perform the check).

Biederman | 12 February 2010, 12:35:32 UTC | sysfs: Document sysfs_attr_init and sysfs_bin_attr_init I have added a new requirement to the external sysfs interface that dynamically allocated sysfs attributes must call sysfs_attr_init if lockdep is enabled. For the time being callying sysfs_attr_init is only mandatory if lockdep is enabled, so we can live with a few unconverted instances until we find them all.

Acknowledge that the logical sysfs rwsem has one instance per sysfs attribute with different locking depencencies for different attributes. There is a sysfs idiom where writing to one sysfs file causes the addition or removal of other sysfs files. Lumping all of the sysfs attributes together in one lock class causes lockdep to generate lots of false positives. This introduces the requirement that non-static sysfs attributes need to be initialized with sysfs_attr_init or sysfs_bin_attr_init. Strictly speaking this requirement only exists when lockdep is enabled, and when lockdep is enabled we get a bit fat warning if this requirement is not met. Signed-off-by: Eric W.

The purpose of the active references are to allows us to block when removing sysfs entries that have custom methods so we don't remove modules while running modular code and to keep those custom methods from accessing data structures after the files have been removed.

This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> | 08 March 2010, 01:04:49 UTC |

Biederman | 01 January 2010, 22:43:53 UTC | sysfs: Cache the last sysfs_dirent to improve readdir scalability v2 When sysfs_readdir stops short we now cache the next sysfs_dirent to return to user space in filp->private_data. There is no impact on the rest of sysfs by doing this and in the common case it allows us to pick up exactly where we left off with no seeking. Additionally I drop and regrab the sysfs_mutex around filldir to avoid a page fault abritrarily increasing the hold time on the sysfs_mutex. v2: Returned to using INT_MAX as the EOF condition. seekdir is ambiguous unless all directory entries have a unique f_pos value.

The problem is that kobject_add_internal() first adds a kobject to the kset and then try to create sysfs directory for it. If the creation fails, it remove the kobject from the kset. get_device_parent() accesses class_dirs kset while only holding class_dirs.list_lock to see whether the cuse class dir exists. But when it exists, it may not have finished initialization yet or may fail and get removed soon. In the above case, the former happened so the second one ends up trying to create subdirectory under NULL sysfs_dirent. Fix it by grabbing a mutex in get_device_parent().

e1d5b65 | Richard Röjfors | 11 February 2010, 09:42:00 UTC | i2c: Add support for Xilinx XPS IIC Bus Interface This patch adds support for the Xilinx XPS IIC Bus Interface. The driver uses the dynamic mode, supporting to put several I2C messages in the FIFO to reduce the number of interrupts. It has the same feature as ocores, it can be passed a list of devices that will be added when the bus is probed.

d84d3ea | Cory Maccarrone | 13 December 2009, 01:54:02 UTC | i2c: omap: Add support for 16-bit registers The current i2c-omap driver is set up for 32-bit registers, which corresponds to most OMAP devices. However, OMAP730/850 based devices use a 16-bit register size. This change modifies the driver to perform a runtime CPU type check to determine the register sizes, and uses a bit shift of either 1 or 2 bits to compute the proper register sizes for all registers.
