Now in 2011 the problem was reported by Gunnar.]\n\nSigned-off-by: Ingo van Lil \u003cinguin@gmx.de\u003e\nSigned-off-by: Richard Weinberger \u003crichard@nod.at\u003e\nReported-by: \u003cgunnarlindroth@hotmail.com\u003e\nTested-by: \u003cgunnarlindroth@hotmail.com\u003e\nCc: Stanislav Meduna \u003cstano@meduna.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b743ac54e54ca18fb7164a97cc77cf1ccee0b0f7", "tree": "a9dced710d289d1594ec2a27ca2a88cef5186ac1", "parents": [ "2a6d0ac182688d4d23357ece744978706c044aad" ], "author": { "name": "Richard Weinberger", "email": "richard@nod.at", "time": "Mon Jul 25 17:12:52 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:13 2011 -0700" }, "message": "um: disable scan_elf_aux() on x86_64\n\nReusing the host\u0027s vDSO makes only sense on x86_32.\n\nSigned-off-by: Richard Weinberger \u003crichard@nod.at\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2a6d0ac182688d4d23357ece744978706c044aad", "tree": "6a8daa134fe8af112b0d234b4ca417a16e59d5e5", "parents": [ "9a8beb93067764344523386e0e5388d3fd78add7" ], "author": { "name": "Davidlohr Bueso", "email": "dave@gnu.org", "time": "Mon Jul 25 17:12:52 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:13 2011 -0700" }, "message": "uml: free resources\n\nWhen creating the temp file there\u0027s a memory and file descriptor leak upon\nerror.\n\nSigned-off-by: Davidlohr Bueso \u003cdave@gnu.org\u003e\nSigned-off-by: Richard Weinberger \u003crichard@nod.at\u003e\nReviewed-by: Vitaliy Ivanov \u003cvitalivanov@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2fdf2130926f07881c75e3905ece472c37d7703f", "tree": "3e9e9c3334f7277aa116800efe6719713e23fdc5", "parents": [ "7a99ae7c57d2de5cad9562bed32addf064521116" ], "author": { "name": "Vitaliy Ivanov", "email": "vitalivanov@gmail.com", "time": "Mon Jul 25 17:12:50 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:13 2011 -0700" }, "message": "uml: helper.c warning corrections\n\nFix this warning:\n\n arch/um/os-Linux/helper.c: In function `helper_child\u0027:\n arch/um/os-Linux/helper.c:38:7: warning: ignoring return value of `write\u0027, declared with attribute warn_unused_result\n\n[richard@nod.at: happens only with -D_FORTIFY_SOURCE\u003d2]\nSigned-off-by: Vitaliy Ivanov \u003cvitalivanov@gmail.com\u003e\nSigned-off-by: Richard Weinberger \u003crichard@nod.at\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f956b3e40ad7b9f7c0d33b80fe78f57fedb74f49", "tree": "44e5b311271d6da81df967de711a78e042d16af9", "parents": [ "22e9b917ab7ccd98046ad9428fb28967f0744605" ], "author": { "name": "Richard Weinberger", "email": "richard@nod.at", "time": "Mon Jul 25 17:12:47 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:12 2011 -0700" }, "message": "um: fix _FORTIFY_SOURCE\u003d2 support for kernel modules\n\nWhen UML is compiled with _FORTIFY_SOURCE we have to export all _chk()\nfunctions which are used in modules.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros.

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.

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" }, { "commit": "11a7ac23a2d7464a74ceb7b97dbae4d5a0208576", "tree": "9b4f26d1675ef802b82b01a8780a58d21c17bd2a", "parents": [ "5134d8fea06ab51459fd095d091d1e6f73a44553" ], "author": { "name": "Jim Meyering", "email": "meyering@redhat.com", "time": "Fri Feb 08 04:22:09 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:43 2008 -0800" }, "message": "uml: improved error handling while locating temp dir\n\n* arch/um/os-Linux/mem.c (make_tempfile): Don\u0027t deref NULL upon failed malloc.\n\n* arch/um/os-Linux/mem.c (make_tempfile): Handle NULL tempdir.\nDon\u0027t let a long tempdir (e.g., via TMPDIR) provoke heap corruption.\n\n[ jdike - formatting cleanups, deleted obsolete comment ]\n\nSigned-off-by: Jim Meyering \u003cmeyering@redhat.com\u003e\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": "5134d8fea06ab51459fd095d091d1e6f73a44553", "tree": "504a84a9290a40f0c98b7c5731b7df82cb357ebe", "parents": [ "536788fe2d28e11db6aeda74207d95d750fb761f" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Fri Feb 08 04:22:08 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:42 2008 -0800" }, "message": "uml: style fixes in arch/um/os-Linux\n\nStyle changes under arch/um/os-Linux:\n\tinclude trimming\n\tCodingStyle fixes\n\tsome printks needed severity indicators\n\nmake_tempfile turns out not to be used outside of mem.c, so it is now static.\nIts declaration in tempfile.h is no longer needed, and tempfile.h itself is no\nlonger needed.\n\ncreate_tmp_file was also made static.\n\ncheckpatch moans about an EXPORT_SYMBOL in user_syms.c which is part of a\nmacro definition - this is copying a bit of kernel infrastructure into the\nlibc side of UML because the kernel headers can\u0027t be included there.\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": "536788fe2d28e11db6aeda74207d95d750fb761f", "tree": "73df2d3a46c542c71d3a84c20c8fd1ce617386a3", "parents": [ "2f569afd9ced9ebec9a6eb3dbf6f83429be0a7b4" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Fri Feb 08 04:22:07 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:42 2008 -0800" }, "message": "uml: runtime host VMSPLIT detection\n\nCalculate TASK_SIZE at run-time by figuring out the host\u0027s VMSPLIT - this is\nneeded on i386 if UML is to run on hosts with varying VMSPLITs without\nrecompilation.\n\nTASK_SIZE is now defined in terms of a variable, task_size.
