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.

The new section \".gnu.hash\" replaces\n\".hash\", and allows for more efficient runtime symbol lookups by the\ndynamic linker. The new ld option --hash-style\u003d{sysv|gnu|both} controls\nwhether to produce the old \".hash\", the new \".gnu.hash\", or both. In some\nnew systems such as Fedora Core 6, gcc by default passes --hash-style\u003dgnu\nto the linker, so that a standard invocation of \"gcc -shared\" results in\nproducing a DSO with only \".gnu.hash\". The new \".gnu.hash\" sections need\nto be dealt with the same way as \".hash\" sections in all respects; only the\ndynamic linker cares about their contents. To work with older dynamic\nlinkers (i.e. preexisting releases of glibc), a binary must have the old\n\".hash\" section. The --hash-style\u003dboth option produces binaries that a new\ndynamic linker can use more efficiently, but an old dynamic linker can\nstill handle.\n\nThe new section runs afoul of the custom linker scripts used to build vDSO\nimages for the kernel. On ia64, the failure mode for this is a boot-time\npanic because the vDSO\u0027s PT_IA_64_UNWIND segment winds up ill-formed.\n\nThis patch addresses the problem in two ways.\n\nFirst, it mentions \".gnu.hash\" in all the linker scripts alongside \".hash\".\n This produces correct vDSO images with --hash-style\u003dsysv (or old tools),\nwith --hash-style\u003dgnu, or with --hash-style\u003dboth.\n\nSecond, it passes the --hash-style\u003dsysv option when building the vDSO\nimages, so that \".gnu.hash\" is not actually produced. This is the most\nconservative choice for compatibility with any old userland. There is some\nconcern that some ancient glibc builds (though not any known old production\nsystem) might choke on --hash-style\u003dboth binaries. The optimizations\nprovided by the new style of hash section do not really matter for a DSO\nwith a tiny number of symbols, as the vDSO has. If someone wants to use\n\u003dgnu or \u003dboth for their vDSO builds and worry less about that\ncompatibility, just change the option and the linker script changes will\nmake any choice work fine.\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nCc: Sam Ravnborg \u003csam@ravnborg.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b5032a50aea76b6230db74b1d171a7f56b204bb7", "tree": "6334709a1ce14ca50fd8a90d94dfac97f8d68edb", "parents": [ "6d76fa58b050044994fe25f8753b8023f2b36737" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Fri Jul 14 15:52:23 2006 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Jul 15 14:42:24 2006 -0700" }, "message": "[PATCH] UML - fix utsname build breakage\n\nSome -mm-only material leaked into a patch destined for mainline, and I didn\u0027t\nnotice.\n\nThis was the replacement of system_utsname with utsname() that\u0027s required by\nthe uts namespace patch.
