* | epoll: introduce resource usage limitsDavide Libenzi2008-12-011-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been thought that the per-user file descriptors limit would also limit the resources that a normal user can request via the epoll interface. Vegard Nossum reported a very simple program (a modified version attached) that can make a normal user to request a pretty large amount of kernel memory, well within the its maximum number of fds. To solve such problem, default limits are now imposed, and /proc based configuration has been introduced. A new directory has been created, named /proc/sys/fs/epoll/ and inside there, there are two configuration points: max_user_instances = Maximum number of devices - per user max_user_watches = Maximum number of "watched" fds - per user The current default for "max_user_watches" limits the memory used by epoll to store "watches", to 1/32 of the amount of the low RAM. As example, a 256MB 32bit machine, will have "max_user_watches" set to roughly 90000. That should be enough to not break existing heavy epoll users. The default value for "max_user_instances" is set to 128, that should be enough too. This also changes the userspace, because a new error code can now come out from EPOLL_CTL_ADD (-ENOSPC). The EMFILE from epoll_create() was already listed, so that should be ok.

Eric Piel has updated it and slimed it up (including the removal of an interface to access to the free-fall feature of the sensor because it is not reliable enough for now). Pavel Machek removed few more features and switched locking from semaphore to mutex. Several people have contributed to the database of the axes.

Move the list of masks to Documentation/acpi/debug.txt (these are copies of the authoritative values in acoutput.h and acpi_drivers.h).

For all the GPEs and Fixed Events, 1. ACPI_EVENT_FLAG_HANDLE is cleared, it's an "invalid" ACPI event. 2. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_DISABLE are set, it's "disabled". 3. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_ENABLE are set, it's "enabled". 4. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set, it's "wake_enabled". Among other things, this prevents incorrect reporting of ACPI events as being "invalid" when it's really just (temporarily) "disabled".
