When this happens, handle_signal will loop, setting up\nthe IRQ stack again because the tearing down had finished, and handling\nwhatever signals had come in.\n\nHowever, to_irq_stack returns a mask of pending signals to be handled, plus\nbit zero is set if the IRQ stack was already active, and thus shouldn\u0027t be\ntorn down. This causes a problem because when handle_signal goes around\nthe loop, sig will be zero, and to_irq_stack will duly set bit zero in the\nreturned mask, faking handle_signal into believing that it shouldn\u0027t tear\ndown the IRQ stack and return thread_info pointers back to their original\nvalues.\n\nThis will eventually cause a crash, as the IRQ stack thread_info will\ncontinue pointing to the original task_struct and an interrupt will look\ninto it after it has been freed.\n\nThe fix is to stop passing a signal number into to_irq_stack. Rather, the\npending signals mask is initialized beforehand with the bit for sig already\nset. References to sig in to_irq_stack can be replaced with references to\nthe mask.\n\n[akpm@linux-foundation.org: use UL]\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" }, { "commit": "c7ec16da5adc1c1b341b2a83bde7add17dcf811a", "tree": "4e11748671da5c83c894f1fe96ce999f33b52e7d", "parents": [ "641916881322a2dee5b120d509a3bdd05a502510" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Thu Aug 30 23:56:17 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Aug 31 01:42:22 2007 -0700" }, "message": "uml: fix linker script alignment bugs\n\nFix a class of bugs in the UML linker scripts which caused section boundary\nvariables to sometimes not line up with their sections.\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" }, { "commit": "4e950f6f0189f65f8bf069cf2272649ef418f5e4", "tree": "95710bedf2a5aa3b61002f3399e0950192fdd504", "parents": [ "673d5b43daa00b42759cecc6b0760b8bf6be80d2" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Jul 30 02:36:13 2007 +0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Sun Jul 29 17:09:29 2007 -0700" }, "message": "Remove fs.h from mm.h\n\nRemove fs.h from mm.h.

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.

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" }, { "commit": "7f0536f80cfbefd753eb123ed20940978f223900", "tree": "98d38ab533082d8145b932bb0e6c4ab86191186a", "parents": [ "f30c2c983e09470446ee00472f9d4a927fe2e9cb" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Sun May 06 14:51:30 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 07 12:13:03 2007 -0700" }, "message": "uml: speed up page table walking\n\nThe previous page table walking code was horribly inefficient.

The underlying cause has been the\nneed to initialize a stack for the new process. The only portable way to\ninitialize a new stack is to set it as the alternate signal stack and take a\nsignal. The signal handler does whatever initialization is needed and jumps\nback to the original stack, where the fork processing is finished. The basic\ncontext switching mechanism is a jmp_buf for each process. You switch to a\nnew process by longjmping to its jmp_buf.\n\nNow that UML has its own implementation of setjmp and longjmp, and I can poke\naround inside a jmp_buf without fear that libc will change the structure, a\nmuch simpler mechanism is possible. The jmpbuf can simply be initialized by\nhand.\n\nThis eliminates -\n\tthe need to set up and remove the alternate signal stack\n\tsending and handling a signal\n\tthe signal blocking needed around the stack switching, since\nthere is no stack switching\n\tsetting up the jmp_buf needed to jump back to the original\nstack after the new one is set up\n\nIn addition, since jmp_buf is now defined by UML, and not by libc, it can be\nembedded in the thread struct. This makes it unnecessary to have it exist on\nthe stack, where it used to be. It also simplifies interfaces, since the\nswitch jmp_buf used to be a void * inside the thread struct, and functions\nwhich took it as an argument needed to define a jmp_buf variable and assign it\nfrom the void *.\n\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": "0915ee38c7db57ff41a7a68bcc02d0dd3b7b849b", "tree": "63b608e830c06fa9eeb102e5fd71d0feb84c4d50", "parents": [ "e3ccf6e3699c879973b616fe681ecaa363457d41" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Wed Sep 27 01:50:38 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 27 08:26:16 2006 -0700" }, "message": "[PATCH] uml: mark some tt-mode code\n\nMark a symbol and file as being tt-mode only.

Some of\nits callers now check the return.\n\nenable_timer is largely tt-mode-specific, so it is marked as such, and the\nonly skas-mode caller is made to call set-interval instead.\n\nuser_time_init was a no-value-added wrapper around set_interval, so it is\ngone.\n\nSince set_interval is now called from kernel code, callers no longer pass\nITIMER_* to it. Instead, they pass a flag which is converted into ITIMER_REAL\nor ITIMER_VIRTUAL.\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" } ], "next": "19bdf0409f25a85a45874a5a8da6f3e4edcf4a49" }
