w1: add fast search for single slave bus

2011-12-10T03:19:18+00:00

This enables a much more efficient way of device searching. It uses the
1-wire read-rom operation which allows the direct reading of the slave
address. BUT this works only with exactly one slave on the bus.

w1: have netlink search update kernel list

2011-05-27T00:12:38+00:00

Reorganize so the netlink connector one wire search command will update
the kernel list of detected slave devices.  Otherwise, a newly detected
device is unusable because unless it's in the kernel list of known devices
any commands will result in ENODEV status.

w1: don't allow arbitrary users to remove w1 devices

2010-10-28T01:03:17+00:00

The search/pullup/add/remove device attributes were 0666 which would allow
arbitrary users to affect the 1 wire bus.  Change to 0664 to prevent that.

I found this patch in the Android tree, apparently this has never been
sent upstream so doing it now.

sysfs: add struct file* to bin_attr callbacks

2010-05-21T16:37:31+00:00

This allows bin_attr->read,write,mmap callbacks to check file specific data
(such as inode owner) as part of any privilege validation.
