* video/sis/: fix negative array indexAdrian Bunk2007-11-151-1/+2
| | | | | | | | | | | | | | This patch fixes the possible usage of a negative value as an array index spotted by the Coverity checker. sisfb_validate_mode() could return a negative error code and we must check for that prior to using its return value as an array index.

* Forbid user to change file flags on quota filesJan Kara2007-11-155-0/+21
| | | | | | | | | | | | | | | | Forbid user from changing file flags on quota files. User has no bussiness in playing with these flags when quota is on. Furthermore there is a remote possibility of deadlock due to a lock inversion between quota file's i_mutex and transaction's start (i_mutex for quota file is locked only when trasaction is started in quota operations) in ext3 and ext4.

* uml: update address space affected by pud_clearJeff Dike2007-11-151-1/+1
| | | | | | | | | | | | | | | | | | | pud_clear wasn't setting the _PAGE_NEWPAGE bit, fooling tlb_flush into thinking that this area of the address space was up-to-date and not unmapping whatever was covered by the pud. This manifested itself as ldconfig on x86_64 complaining about the first library it looked at not being a valid ELF file. A config file is mapped at 0x4000000, as the only thing mapped under its pud, and unmapped. The unmapping caused a pud_clear, which, due to this bug, didn't actually unmap the config file data on the host. The first library is then mapped at the same location, but is not actually mapped on the host because accesses to it cause no page faults. As a result, ldconfig sees the old config file data.

| | | | | | | | | | Stupid bug - we need to compare the return value of recvmsg to the value of iov_len, not its size.

* oProfile: oops when profile_pc() returns ~0LUPhilippe Elie2007-11-153-0/+12
| | | | | | | | | | | | | | | | | Instruction pointer returned by profile_pc() can be a random value. This break the assumption than we can safely set struct op_sample.eip field to a magic value to signal to the per-cpu buffer reader side special event like task switch ending up in a segfault in get_task_mm() when profile_pc() return ~0UL. Fixed by sanitizing the sampled eip and reject/log invalid eip. Problem reported by Sami Farin, patch tested by him.

* RTCs: handle NVRAM betterDavid Brownell2007-11-154-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several of the RTC drivers are exporting binary "nvram" files in sysfs. Such NVRAM (or on many systems, EEPROM) data is often initialized during system manufacture to hold data about identity (serial numbers, Ethernet addresses, etc), configuration, calibration, and so forth. This patch improves integrity and security of those files: - Correctly initializes the size in one of the two cases where that was not yet being done. - Improves system security/integrity by making this state not be world-writable by default. Letting arbitrary userspace code mangle such state by default is at least Not A Good Thing; and it could sometimes be worse, depending on the particular data that might be corrupted. (I disregard the paranoiac "don't let anyone read it either" approach. Anyone storing passwords in such memory doesn't really care about security.)

* rtc_hctosys expects RTCs in UTC (doc)David Brownell2007-11-152-3/+5
| | | | | | | | | | | | | | The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local time (e.g. PST). Say so in Kconfig and in the kernel message. (Strictly speaking, the RTC clock should be tracking the POSIX epoch. That's not worth going into here. Goofing timezones means clocks are wrong by many hours; the POSIX-v-UTC differences just cost seconds.)

| * hwmon: (f75375s) Allow setting up fans with platform_dataRiku Voipio2007-11-082-7/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | Allow initializing fans on systems where BIOS does not do that by default. - define f75375s_platform_data in new file f75375s.h - if platform_data was provided, set fans accordingly in f75375_init() - split set_pwm_enable() to a sysfs callback and directly usable set_pwm_enable_direct() Signed-off-by: Riku Voipio <riku.voipio@movial.fi> Signed-off-by: Mark M.

| | | | | | | | | | | | | | | | | | | | | | | | | | Following the example of David Brownell's work on lm75: - Create a second driver struct, using new-style driver binding methods. - Rename the old driver struct as f75375_legacy_driver. - Make the legacy bind/unbind logic delegate all its work.

| * hwmon: (applesmc) Add support for Mac Pro 2 x Quad-CoreRené Rebe2007-11-081-6/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least the 2x Quad-Core Apple Mac Pro appears to have some over-heat protection which suddenly powers off the whole box under load. This adds support for the fans and temerature sensors in the Mac Pro - later some "windwarm" a-like code should probably monitor the values. For now manually tweaking the fans prevents the sudden shutdown for me. cd /sys/devices/platform/applesmc.768 for x in fan{1,2,3,4}; do echo 1 > ${x}_manual echo 1285 > ${x}_output done Two sensors are 0, while four are 129 °C, those might be removed again, later.
