check for minimal type compatibility\n\nNow that we\u0027ve renamed probe_kernel_address() to get_kernel_nofault()\nand made it look and behave more in line with get_user(), some of the\nsubtle type behavior differences end up being more obvious and possibly\ndangerous.\n\nWhen you do\n\n get_user(val, user_ptr);\n\nthe type of the access comes from the \"user_ptr\" part, and the above\nbasically acts as\n\n val \u003d *user_ptr;\n\nby design (except, of course, for the fact that the actual dereference\nis done with a user access).\n\nNote how in the above case, the type of the end result comes from the\npointer argument, and then the value is cast to the type of \u0027val\u0027 as\npart of the assignment.\n\nSo the type of the pointer is ultimately the more important type both\nfor the access itself.\n\nBut \u0027get_kernel_nofault()\u0027 may now _look_ similar, but it behaves very\ndifferently. When you do\n\n get_kernel_nofault(val, kernel_ptr);\n\nit behaves like\n\n val \u003d *(typeof(val) *)kernel_ptr;\n\nexcept, of course, for the fact that the actual dereference is done with\nexception handling so that a faulting access is suppressed and returned\nas the error code.\n\nBut note how different the casting behavior of the two superficially\nsimilar accesses are: one does the actual access in the size of the type\nthe pointer points to, while the other does the access in the size of\nthe target, and ignores the pointer type entirely.\n\nActually changing get_kernel_nofault() to act like get_user() is almost\ncertainly the right thing to do eventually, but in the meantime this\npatch adds logit to at least verify that the pointer type is compatible\nwith the type of the result.\n\nIn many cases, this involves just casting the pointer to \u0027void *\u0027 to\nmake it obvious that the type of the pointer is not the important part.\nIt\u0027s not how \u0027get_user()\u0027 acts, but at least the behavioral difference\nis now obvious and explicit.\n\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "25f12ae45fc1931a1dce3cc59f9989a9d87834b0", "tree": "c89ffb14ca4cbe9afbf312be9e983377c6de5f35", "parents": [ "c0ee37e85e0e47402b8bbe35b6cec8e06937ca58" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed Jun 17 09:37:55 2020 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jun 18 11:14:40 2020 -0700" }, "message": "maccess: rename probe_kernel_address to get_kernel_nofault\n\nBetter describe what this helper does, and match the naming of\ncopy_from_kernel_nofault.\n\nAlso switch the argument order around, so that it acts and looks\nlike get_user().\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "670d0a4b10704667765f7d18f7592993d02783aa", "tree": "3ec6a6eb53fde1e6f25fb0c2e85470b54e5615be", "parents": [ "1b5044021070efa3259f3e9548dc35d1eb6aa844" ], "author": { "name": "Luc Van Oostenryck", "email": "luc.vanoostenryck@gmail.com", "time": "Thu Jun 18 00:02:26 2020 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jun 18 10:05:23 2020 -0700" }, "message": "sparse: use identifiers to define address spaces\n\nCurrently, address spaces in warnings are displayed as \u0027\u003casn:X\u003e\u0027 with\n\u0027X\u0027 being the address space\u0027s arbitrary number.\n\nBut since sparse v0.6.0-rc1 (late December 2018), sparse allows you to\ndefine the address spaces using an identifier instead of a number.
