* [SPARC64]: Partially revert "Constify function pointer tables."David S. Miller2008-01-231-1/+1
| | | | | | | | | | | | | This partially reverts 872e2be7c4056496c2871bd9b0f2fae6c374fe47 (Constify function pointer tables.)

* [SPARC64]: Fix two kernel linear mapping setup bugs.David S. Miller2007-12-132-9/+32
| | | | | | | | | | | | | | | | This was caught and identified by Greg Onufer. Since we setup the 256M/4M bitmap table after taking over the trap table, it's possible for some 4M mapping to get loaded in the TLB beforhand which later will be 256M mappings. This can cause illegal TLB multiple-match conditions. Fix this by setting up the bitmap before we take over the trap table. Next, __flush_tlb_all() was not doing anything on hypervisor platforms. Fix by adding sun4v_mmu_demap_all() and calling it. Signed-off-by: David S. Miller <davem@davemloft.net>

* | pid namespaces: changes to show virtual ids to userPavel Emelyanov2007-10-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the largest patch in the set. Make all (I hope) the places where the pid is shown to or get from user operate on the virtual pids. The idea is: - all in-kernel data structures must store either struct pid itself or the pid's global nr, obtained with pid_nr() call; - when seeking the task from kernel code with the stored id one should use find_task_by_pid() call that works with global pids; - when showing pid's numerical value to the user the virtual one should be used, but however when one shows task's pid outside this task's namespace the global one is to be used; - when getting the pid from userspace one need to consider this as the virtual one and use appropriate task/pid-searching functions.

The proposals are to * equip the functions that return the integer with _nr suffix to represent that fact, * and to make all functions work with task (not process) by making the common prefix of the same name. For monotony the routines signal_session() and set_signal_session() are replaced with task_session_nr() and set_task_session(), especially since they are only used with the explicit task->signal dereference.

* | core_pattern: ignore RLIMIT_CORE if core_pattern is a pipeNeil Horman2007-10-171-6/+4

This infrastructure however has some shortcommings which can be enhanced. Specifically: 1) The coredump code in the kernel should ignore RLIMIT_CORE limitation when core_pattern is a pipe, since file system resources are not being consumed in this case, unless the user application wishes to save the core, at which point the app is restricted by usual file system limits and restrictions. 2) The core_pattern code should be able to parse and pass options to the user space helper as an argv array. The real core limit of the uid of the crashing proces should also be passable to the user space helper (since it is overridden to zero when called). 3) Some miscellaneous bugs need to be cleaned up (specifically the recognition of a recursive core dump, should the user mode helper itself crash. Also, the core dump code in the kernel should not wait for the user mode helper to exit, since the same context is responsible for writing to the pipe, and a read of the pipe by the user mode helper will result in a deadlock. This patch: Remove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that core_pattern is a pipe, the entire core will be fed to the user mode helper.
