Interrupt enabling and disabling no\nlonger map to sigprocmask. Rather, a flag is set indicating whether\ninterrupts may be handled. If a signal comes in and interrupts are marked as\nOK, then it is handled normally. If interrupts are marked as off, then the\nsignal handler simply returns after noting that a signal needs handling. When\ninterrupts are enabled later on, this pending signals flag is checked, and the\nIRQ handlers are called at that point.\n\nThe point of this is to reduce the cost of local_irq_save et al, since they\nare very much more common than the signals that they are enabling and\ndisabling. Soft interrupts produce a speed-up of ~25% on a kernel build.\n\nSubtleties -\n\n UML uses sigsetjmp/siglongjmp to switch contexts. sigsetjmp has been\n wrapped in a save_flags-like macro which remembers the interrupt state at\n setjmp time, and restores it when it is longjmp-ed back to.\n\n The enable_signals function has to loop because the IRQ handler\n disables interrupts before returning. enable_signals has to return with\n signals enabled, and signals may come in between the disabling and the\n return to enable_signals. So, it loops for as long as there are pending\n signals, ensuring that signals are enabled when it finally returns, and\n that there are no pending signals that need to be dealt with.\n\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton

With -mm1, the expansion is now a quote-delimited\nstring, so there needs to be a definition of it.\n\nSince kernel-offsets.c is basically the same as other arches\u0027 asm-offsets.c,\nand those seem to build OK, this patch turns kernel-offsets.c into\nasm-offsets.c. kernel-offsets.c is in arch/um/sys-$(SUBARCH), i.e. sys-i386\nand sys-x86_64, while kbuild expects it to be in arch/um/kernel.\nkernel-offsets.c is moved to\narch/um/include/sysdep-$(SUBARCH)/kernel-offsets.h, which is included by\narch/um/kernel/asm-offsets.c. With that, include/asm-um/asm-offsets.h is\ngenerated automatically. kernel-offsets.h continues to exist because it needs\nto be accessible to userspace UML code, and include/asm-um isn\u0027t. So, a\nsymlink is made from arch/um/include/kernel-offsets.h to\ninclude/asm-um/asm-offsets.h.\n\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ea2ba7dc3dd3f85034e6da6abacc813d723a2ad5", "tree": "56f3d2a22d3ba3d91042d9a536b659b9c967dc03", "parents": [ "0805d89c151b4800eade4c2f50d39c5253d7d054" ], "author": { "name": "Gennady Sharapov", "email": "Gennady.V.Sharapov@intel.com", "time": "Sun Jan 08 01:01:31 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:39 2006 -0800" }, "message": "[PATCH] uml: move libc-dependent code from trap_user.c\n\nThe serial UML OS-abstraction layer patch (um/kernel dir).\n\nThis moves all systemcalls from trap_user.c file under os-Linux dir\n\nSigned-off-by: Gennady Sharapov \u003cGennady.V.Sharapov@intel.com\u003e\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0805d89c151b4800eade4c2f50d39c5253d7d054", "tree": "3ff8a48973e266f5e9eccf6aa38c80282aef12ca", "parents": [ "b2de464f7f0006bec162559a8db161869d32ee93" ], "author": { "name": "Gennady Sharapov", "email": "Gennady.V.Sharapov@intel.com", "time": "Sun Jan 08 01:01:29 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:39 2006 -0800" }, "message": "[PATCH] uml: move libc-dependent code from signal_user.c\n\nThe serial UML OS-abstraction layer patch (um/kernel dir).\n\nThis moves all systemcalls from signal_user.c file under os-Linux dir\n\nSigned-off-by: Gennady Sharapov \u003cGennady.V.Sharapov@intel.com\u003e\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "7b033e1fdeef3d8bacac3cd5cfa53c9d670d1f3d", "tree": "632948968ea0d61bc323f419866d3d037a99f0a5", "parents": [ "44700a4469b6bb89e6f1edd32b8a4a915dd967c6" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Fri Jan 06 00:19:03 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:47 2006 -0800" }, "message": "[PATCH] uml: add mconsole_reply variant with length param\n\nThis is needed for the console output patch, since we have a possibly\nnon-NULL-terminated string there.

This caused equivalent changes in the arguments to line_timer_cb.\nline_disable is gone since it is not used any more.\n\nThe count field in the line structure is gone. tty-\u003ecount is used instead.\n\nThe complicated logic in sigio_handler with freeing IRQs when necessary and\nmaking sure its idea of the next irq is correct is now much simpler.

While sysrq-t\ndoes the same thing, sysrq-t shows *all* threads stacks. It also doesn\u0027t work\nright now. In the future, I thought it might be acceptable to make this show\nall pids stacks, but perhaps leaving well enough alone and just using sysrq-t\nwould be okay. For now, upon receiving the stack command, UML switches\ncontext to that thread, dumps its registers, and then switches context back to\nthe original thread. Since UML compacts all threads into one of 4 host\nthreads, this sort of mechanism could be expanded in the future to include\nother debugging helpers that sysrq does not cover.\n\nNote by jdike - The main benefit to this is that it brings an arbitrary thread\nback into context, where it can be examined by gdb.

It provides the security of\nthe skas host patch, and some of the performance gains.\n\nThe two main things that are provided by the skas patch, /proc/mm and\nPTRACE_FAULTINFO, are implemented in a way that require no host patch.\n\nFor the remote address space changing stuff (mmap, munmap, and mprotect),\nwe set aside two pages in the process above its stack, one of which\ncontains a little bit of code which can call mmap et al.\n\nTo update the address space, the system call information (system call\nnumber and arguments) are written to the stub page above the code. The\n%esp is set to the beginning of the data, the %eip is set the the start of\nthe stub, and it repeatedly pops the information into its registers and\nmakes the system call until it sees a system call number of zero. This is\nto amortize the cost of the context switch across multiple address space\nupdates.\n\nWhen the updates are done, it SIGSTOPs itself, and the kernel process\ncontinues what it was doing.\n\nFor a PTRACE_FAULTINFO replacement, we set up a SIGSEGV handler in the\nchild, and let it handle segfaults rather than nullifying them. The\nhandler is in the same page as the mmap stub. The second page is used as\nthe stack. The handler reads cr2 and err from the sigcontext, sticks them\nat the base of the stack in a faultinfo struct, and SIGSTOPs itself. The\nkernel then reads the faultinfo and handles the fault.\n\nA complication on x86_64 is that this involves resetting the registers to\nthe segfault values when the process is inside the kill system call. This\nbreaks on x86_64 because %rcx will contain %rip because you tell SYSRET\nwhere to return to by putting the value in %rcx. So, this corrupts $rcx on\nreturn from the segfault. To work around this, I added an\narch_finish_segv, which on x86 does nothing, but which on x86_64 ptraces\nthe child back through the sigreturn. This causes %rcx to be restored by\nsigreturn and avoids the corruption. Ultimately, I think I will replace\nthis with the trick of having it send itself a blocked signal which will be\nunblocked by the sigreturn. This will allow it to be stopped just after\nthe sigreturn, and PTRACE_SYSCALLed without all the back-and-forth of\nPTRACE_SYSCALLing it through sigreturn.\n\nThis runs on a stock host, so theoretically (and hopefully), tt mode isn\u0027t\nneeded any more. We need to make sure that this is better in every way\nthan tt mode, though. I\u0027m concerned about the speed of address space\nupdates and page fault handling, since they involve extra round-trips to\nthe child. We can amortize the round-trip cost for large address space\nupdates by writing all of the operations to the data page and having the\nchild execute them all at the same time. This will help fork and exec, but\nnot page faults, since they involve only one page.\n\nI can\u0027t think of any way to help page faults, except to add something like\nPTRACE_FAULTINFO to the host. There is PTRACE_SIGINFO, but UML doesn\u0027t use\nsiginfo for SIGSEGV (or anything else) because there isn\u0027t enough\ninformation in the siginfo struct to handle page faults (the faulting\noperation type is missing). Adding that would make PTRACE_SIGINFO a usable\nequivalent to PTRACE_FAULTINFO.\n\nAs for the code itself:\n\n- The system call stub is in arch/um/kernel/sys-$(SUBARCH)/stub.S. It is\n put in its own section of the binary along with stub_segv_handler in\n arch/um/kernel/skas/process.c. This is manipulated with run_syscall_stub\n in arch/um/kernel/skas/mem_user.c. syscall_stub will execute any system\n call at all, but it\u0027s only used for mmap, munmap, and mprotect.\n\n- The x86_64 stub calls sigreturn by hand rather than allowing the normal\n sigreturn to happen, because the normal sigreturn is a SA_RESTORER in\n UML\u0027s address space provided by libc. Needless to say, this is not\n available in the child\u0027s address space. Also, it does a couple of odd\n pops before that which restore the stack to the state it was in at the\n time the signal handler was called.\n\n- There is a new field in the arch mmu_context, which is now a union.\n This is the pid to be manipulated rather than the /proc/mm file\n descriptor. Code which deals with this now checks proc_mm to see whether\n it should use the usual skas code or the new code.\n\n- userspace_tramp is now used to create a new host process for every UML\n process, rather than one per UML processor. It checks proc_mm and\n ptrace_faultinfo to decide whether to map in the pages above its stack.\n\n- start_userspace now makes CLONE_VM conditional on proc_mm since we need\n separate address spaces now.\n\n- switch_mm_skas now just sets userspace_pid[0] to the new pid rather\n than PTRACE_SWITCH_MM. There is an addition to userspace which updates\n its idea of the pid being manipulated each time around the loop. This is\n important on exec, when the pid will change underneath userspace().\n\n- The stub page has a pte, but it can\u0027t be mapped in using tlb_flush\n because it is part of tlb_flush. This is why it\u0027s required for it to be\n mapped in by userspace_tramp.\n\nOther random things:\n\n- The stub section in uml.lds.S is page aligned. This page is written\n out to the backing vm file in setup_physmem because it is mapped from\n there into user processes.\n\n- There\u0027s some confusion with TASK_SIZE now that there are a couple of\n extra pages that the process can\u0027t use. TASK_SIZE is considered by the\n elf code to be the usable process memory, which is reasonable, so it is\n decreased by two pages. This confuses the definition of\n USER_PGDS_IN_LAST_PML4, making it too small because of the rounding down\n of the uneven division. So we round it to the nearest PGDIR_SIZE rather\n than the lower one.\n\n- I added a missing PT_SYSCALL_ARG6_OFFSET macro.\n\n- um_mmu.h was made into a userspace-usable file.\n\n- proc_mm and ptrace_faultinfo are globals which say whether the host\n supports these features.\n\n- There is a bad interaction between the mm.nr_ptes check at the end of\n exit_mmap, stack randomization, and skas0. exit_mmap will stop freeing\n pages at the PGDIR_SIZE boundary after the last vma. If the stack isn\u0027t\n on the last page table page, the last pte page won\u0027t be freed, as it\n should be since the stub ptes are there, and exit_mmap will BUG because\n there is an unfreed page. To get around this, TASK_SIZE is set to the\n next lowest PGDIR_SIZE boundary and mm-\u003enr_ptes is decremented after the\n calls to init_stub_pte.
