2013-11-13backlight: lp855x_bl: support new LP8555 deviceMilo Kim5-7/+67
LP8555 is one of the LP855x family devices. This device needs pre_init_device() and post_init_device() driver structure. It's same as LP8557, so the device configuration code is shared with LP8557. Backlight outputs are generated from dual DC-DC boost converters. It's configurable EPROM settings which are defined in the platform data. Driver documentation and device tree bindings are updated.

2013-11-13kernel/printk/printk.c: enable boot delay for earlyprintkDave Young1-2/+2

2013-11-13vsprintf: check real user/group id for %pKRyan Mallon2-10/+48
Some setuid binaries will allow reading of files which have read permission by the real user id. This is problematic with files which use %pK because the file access permission is checked at open() time, but the kptr_restrict setting is checked at read() time. If a setuid binary opens a %pK file as an unprivileged user, and then elevates permissions before reading the file, then kernel pointer values may be leaked. This happens for example with the setuid pppd application on Ubuntu 12.04: $ head -1 /proc/kallsyms 00000000 T startup_32 $ pppd file /proc/kallsyms pppd: In file /proc/kallsyms: unrecognized option 'c1000000' This will only leak the pointer value from the first line, but other setuid binaries may leak more information. Fix this by adding a check that in addition to the current process having CAP_SYSLOG, that effective user and group ids are equal to the real ids. If a setuid binary reads the contents of a file which uses %pK then the pointer values will be printed as NULL if the real user is unprivileged. Update the sysctl documentation to reflect the changes, and also correct the documentation to state the kptr_restrict=0 is the default. This is a only temporary solution to the issue. The correct solution is to do the permission check at open() time on files, and to replace %pK with a function which checks the open() time permission. %pK uses in printk should be removed since no sane permission check can be done, and instead protected by using dmesg_restrict.
