      "message": "uml: random driver fixes\n\nThe random driver would essentially hang if the host\u0027s /dev/random returned\n-EAGAIN.  There was a test of need_resched followed by a schedule inside the\nloop, but that didn\u0027t help and it\u0027s the wrong way to work anyway.\n\nThe right way is to ask for an interrupt when there is input available from\nthe host and handle it then rather than polling.\n\nNow, when the host\u0027s /dev/random returns -EAGAIN, the driver asks for a wakeup\nwhen there\u0027s randomness available again and sleeps.  The interrupt routine\njust wakes up whatever processes are sleeping on host_read_wait.\n\nThere is an atomic_t, host_sleep_count, which counts the number of processes\nwaiting for randomness.  When this reaches zero, the interrupt is disabled.\n\nAn added complication is that async I/O notification was only recently added\nto /dev/random (by me), so essentially all hosts will lack it.  So, we use the\nsigio workaround here, which is to have a separate thread poll on the\ndescriptor and send an interrupt when there is input on it.  This mechanism is\nactivated when a process gets -EAGAIN (activating this multiple times is\nharmless, if a bit wasteful) and deactivated by the last process still\nwaiting.\n\nThe module name was changed from \"random\" to \"hw_random\" in order for udev to\nrecognize it.\n\nThe sigio workaround needed some changes.  sigio_broken was added for cases\nwhen we know that async notification doesn\u0027t work.  This is now called from\nmaybe_sigio_broken, which deals with pts devices.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "uml: fix FP register corruption\n\nCommit ee3d9bd4de1ed93d2a7ee41c331ed30a1c7b8acd (\"uml: simplify SIGSEGV\nhandling\"), while greatly simplifying the kernel SIGSEGV handler that\nruns in the process address space, introduced a bug which corrupts FP\nstate in the process.\n\nPreviously, the SIGSEGV handler called the sigreturn system call by hand - it\ncouldn\u0027t return through the restorer provided to it because that could try to\ncall the libc restorer which likely wouldn\u0027t exist in the process address\nspace.  So, it blocked off some signals, including SIGUSR1, on entry to the\nSIGSEGV handler, queued a SIGUSR1 to itself, and invoked sigreturn.  The\nSIGUSR1 was delivered, and was visible to the UML kernel after sigreturn\nfinished.\n\nThe commit eliminated the signal masking and the call to sigreturn.  The\nhandler simply hits itself with a SIGTRAP to let the UML kernel know that it\nis finished.  UML then restores the process registers, which effectively\nlongjmps the process out of the signal handler, skipping sigreturn\u0027s restoring\nof register state and the signal mask.\n\nThe bug is that the host apparently sets used_fp to 0 when it saves the\nprocess FP state in the sigcontext on the process signal stack.  Thus, when\nthe process is longjmped out of the handler, its FP state is corrupt because\nit wasn\u0027t saved on the context switch to the UML kernel.\n\nThis manifested itself as sleep hanging.  For some reason, sleep uses floating\npoint in order to calculate the sleep interval.  When a page fault corrupts\nits FP state, it is faked into essentially sleeping forever.\n\nThis patch saves the FP state before entering the SIGSEGV handler and restores\nit afterwards.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "uml: cover stubs with a VMA\n\nGive the stubs a VMA.  This allows the removal of a truly nasty kludge to make\nsure that mm-\u003enr_ptes was correct in exit_mmap.  The underlying problem was\nalways that the stubs, which have ptes, and thus allocated a page table,\nweren\u0027t covered by a VMA.\n\nThis patch fixes that by using install_special_mapping in arch_dup_mmap and\nactivate_context to create the VMA.  The stubs have to be moved, since\nshift_arg_pages seems to assume that the stack is the only VMA present at that\npoint during exec, and uses vma_adjust to fiddle its VMA.  However, that\nextends the stub VMA by the amount removed from the stack VMA.\n\nTo avoid this problem, the stubs were moved to a different fixed location at\nthe start of the address space.\n\nThe init_stub_pte calls were moved from init_new_context to arch_dup_mmap\nbecause I was occasionally seeing arch_dup_mmap not being called, causing\nexit_mmap to die.  Rather than figure out what was really happening, I decided\nit was cleaner to just move the calls so that there\u0027s no doubt that both the\npte and VMA creation happen, no matter what.  arch_exit_mmap is used to clear\nthe stub ptes at exit time.\n\nThe STUB_* constants in as-layout.h no longer depend on UM_TASK_SIZE, that\nthat definition is removed, along with the comments complaining about gcc.\n\nBecause the stubs are no longer at the top of the address space, some care is\nneeded while flushing TLBs.  update_pte_range checks for addresses in the stub\nrange and skips them.  flush_thread now issues two unmaps, one for the range\nbefore STUB_START and one for the range after STUB_END.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "uml: kill processes instead of panicing kernel\n\nUML was panicing in the case of failures of libc calls which shouldn\u0027t happen.\n This is an overreaction since a failure from libc doesn\u0027t normally mean that\nkernel data structures are in an unknown state.  Instead, the current process\nshould just be killed if there is no way to recover.\n\nThe case that prompted this was a failure of PTRACE_SETREGS restoring the same\nstate that was read by PTRACE_GETREGS.  It appears that when a process tries\nto load a bogus value into a segment register, it segfaults (as expected) and\nthe value is actually loaded and is seen by PTRACE_GETREGS (not expected).\n\nThis case is fixed by forcing a fatal SIGSEGV on the process so that it\nimmediately dies.  fatal_sigsegv was added for this purpose.  It was declared\nas noreturn, so in order to pursuade gcc that it actually does not return, I\nadded a call to os_dump_core (and declared it noreturn) so that I get a core\nfile if somehow the process survives.\n\nAll other calls in arch/um/os-Linux/skas/process.c got the same treatment,\nwith failures causing the process to die instead of a kernel panic, with some\nexceptions.\n\nuserspace_tramp exits with status 1 if anything goes wrong there.  That will\ncause start_userspace to return an error.  copy_context_skas0 and\nmap_stub_pages also now return errors instead of panicing.  Callers of thes\nfunctions were changed to check for errors and do something appropriate.\nUsually that\u0027s to return an error to their callers.\ncheck_skas3_ptrace_faultinfo just exits since that\u0027s too early to do anything\nelse.\n\nsave_registers, restore_registers, and init_registers now return status\ninstead of panicing on failure, with their callers doing something\nappropriate.\n\nThere were also duplicate declarations of save_registers and restore_registers\nin os.h - these are gone.\n\nI noticed and fixed up some whitespace damage.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The declarations in it are variables which either don\u0027t\nexist or which don\u0027t have global scope.  The one exception is\nkill_off_processes_skas.  If that\u0027s removed, this header can be deleted.\n\nThis uncovered a bug in user.h, which wasn\u0027t correctly making sure that a\nsize_t definition was available to both userspace and kernelspace files.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "uml: iRQ stacks\n\nAdd a separate IRQ stack.  This differs from i386 in having the entire\ninterrupt run on a separate stack rather than starting on the normal kernel\nstack and switching over once some preparation has been done.  The underlying\nmechanism, is of course, sigaltstack.\n\nAnother difference is that interrupts that happen in userspace are handled on\nthe normal kernel stack.  These cause a wait wakeup instead of a signal\ndelivery so there is no point in trying to switch stacks for these.  There\u0027s\nno other stuff on the stack, so there is no extra stack consumption.\n\nThis quirk makes it possible to have the entire interrupt run on a separate\nstack - process preemption (and calls to schedule()) happens on a normal\nkernel stack.  If we enable CONFIG_PREEMPT, this will need to be rethought.\n\nThe IRQ stack for CPU 0 is declared in the same way as the initial kernel\nstack.  IRQ stacks for other CPUs will be allocated dynamically.\n\nAn extra field was added to the thread_info structure.  When the active\nthread_info is copied to the IRQ stack, the real_thread field points back to\nthe original stack.  This makes it easy to tell where to copy the thread_info\nstruct back to when the interrupt is finished.  It also serves as a marker of\na nested interrupt.  It is NULL for the first interrupt on the stack, and\nnon-NULL for any nested interrupts.\n\nCare is taken to behave correctly if a second interrupt comes in when the\nthread_info structure is being set up or taken down.  I could just disable\ninterrupts here, but I don\u0027t feel like giving up any of the performance gained\nby not flipping signals on and off.\n\nIf an interrupt comes in during these critical periods, the handler can\u0027t run\nbecause it has no idea what shape the stack is in.  So, it sets a bit for its\nsignal in a global mask and returns.  The outer handler will deal with this\nsignal itself.\n\nAtomicity is had with xchg.  A nested interrupt that needs to bail out will\nxchg its signal mask into pending_mask and repeat in case yet another\ninterrupt hit at the same time, until the mask stabilizes.\n\nThe outermost interrupt will set up the thread_info and xchg a zero into\npending_mask when it is done.  At this point, nested interrupts will look at\n-\u003ereal_thread and see that no setup needs to be done.  They can just continue\nnormally.\n\nSimilar care needs to be taken when exiting the outer handler.  If another\ninterrupt comes in while it is copying the thread_info, it will drop a bit\ninto pending_mask.  The outer handler will check this and if it is non-zero,\nwill loop, set up the stack again, and handle the interrupt.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "uml: start fixing os_read_file and os_write_file\n\nThis patch starts the removal of a very old, very broken piece of code.  This\nstems from the problem of passing a userspace buffer into read() or write() on\nthe host.  If that buffer had not yet been faulted in, read and write will\nreturn -EFAULT.\n\nTo avoid this problem, the solution was to fault the buffer in before the\nsystem call by touching the pages that hold the buffer by doing a copy-user of\na byte to each page.  This is obviously bogus, but it does usually work, in tt\nmode, since the kernel and process are in the same address space and userspace\naddresses can be accessed directly in the kernel.\n\nIn skas mode, where the kernel and process are in separate address spaces, it\nis completely bogus because the userspace address, which is invalid in the\nkernel, is passed into the system call instead of the corresponding physical\naddress, which would be valid.  Here, it appears that this code, on every host\nread() or write(), tries to fault in a random process page.  This doesn\u0027t seem\nto cause any correctness problems, but there is a performance impact.  This\npatch, and the ones following, result in a 10-15% performance gain on a kernel\nbuild.\n\nThis code can\u0027t be immediately tossed out because when it is, you can\u0027t log\nin.  Apparently, there is some code in the console driver which depends on\nthis somehow.\n\nHowever, we can start removing it by switching the code which does I/O using\nkernel addresses to using plain read() and write().  This patch introduces\nos_read_file_k and os_write_file_k for use with kernel buffers and converts\nall call locations which use obvious kernel buffers to use them.  These\ninclude I/O using buffers which are local variables which are on the stack or\nkmalloc-ed.  Later patches will handle the less obvious cases, followed by a\nmass conversion back to the original interface.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
