This patch creates an entry called\nKernelPageSize in /proc/pid/smaps that is the size of page used by the\nkernel to back a VMA. The entry is not called PageSize as it is possible\nthe MMU uses a different size. This extension should not break any sensible\nparser that skips lines containing unrecognised information.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: \"KOSAKI Motohiro\" \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Alexey Dobriyan \u003cadobriyan@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": "ac8cc0fa5395fe2278e305a4cbed48e90d88d878", "tree": "515f577bfddd054ee4373228be7c974dfb8133af", "parents": [ "238c6d54830c624f34ac9cf123ac04aebfca5013", "3699c53c485bf0168e6500d0ed18bf931584dd7c" ], "author": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Wed Jan 07 09:58:22 2009 +1100" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Wed Jan 07 09:58:22 2009 +1100" }, "message": "Merge branch \u0027next\u0027 into for-linus\n" }, { "commit": "3699c53c485bf0168e6500d0ed18bf931584dd7c", "tree": "eee63a8ddbdb0665bc6a4a053a2405ca7a5b867f", "parents": [ "29881c4502ba05f46bc12ae8053d4e08d7e2615c" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Jan 06 22:27:01 2009 +0000" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Wed Jan 07 09:38:48 2009 +1100" }, "message": "CRED: Fix regression in cap_capable() as shown up by sys_faccessat() [ver #3]\n\nFix a regression in cap_capable() due to:\n\n\tcommit 3b11a1decef07c19443d24ae926982bc8ec9f4c0\n\tAuthor: David Howells \u003cdhowells@redhat.com\u003e\n\tDate: Fri Nov 14 10:39:26 2008 +1100\n\n\t CRED: Differentiate objective and effective subjective credentials on a task\n\nThe problem is that the above patch allows a process to have two sets of\ncredentials, and for the most part uses the subjective credentials when\naccessing current\u0027s creds.\n\nThere is, however, one exception: cap_capable(), and thus capable(), uses the\nreal/objective credentials of the target task, whether or not it is the current\ntask.\n\nOrdinarily this doesn\u0027t matter, since usually the two cred pointers in current\npoint to the same set of creds. However, sys_faccessat() makes use of this\nfacility to override the credentials of the calling process to make its test,\nwithout affecting the creds as seen from other processes.\n\nOne of the things sys_faccessat() does is to make an adjustment to the\neffective capabilities mask, which cap_capable(), as it stands, then ignores.\n\nThe affected capability check is in generic_permission():\n\n\tif (!(mask \u0026 MAY_EXEC) || execute_ok(inode))\n\t\tif (capable(CAP_DAC_OVERRIDE))\n\t\t\treturn 0;\n\nThis change passes the set of credentials to be tested down into the commoncap\nand SELinux code. The security functions called by capable() and\nhas_capability() select the appropriate set of credentials from the process\nbeing checked.\n\nThis can be tested by compiling the following program from the XFS testsuite:\n\n/*\n * t_access_root.c - trivial test program to show permission bug.\n *\n * Written by Michael Kerrisk - copyright ownership not pursued.\n * Sourced from: http://linux.derkeiler.com/Mailing-Lists/Kernel/2003-10/6030.html\n */\n#include \u003climits.h\u003e\n#include \u003cunistd.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003cstdlib.h\u003e\n#include \u003cfcntl.h\u003e\n#include \u003csys/stat.h\u003e\n\n#define UID 500\n#define GID 100\n#define PERM 0\n#define TESTPATH \"/tmp/t_access\"\n\nstatic void\nerrExit(char *msg)\n{\n perror(msg);\n exit(EXIT_FAILURE);\n} /* errExit */\n\nstatic void\naccessTest(char *file, int mask, char *mstr)\n{\n printf(\"access(%s, %s) returns %d\\n\", file, mstr, access(file, mask));\n} /* accessTest */\n\nint\nmain(int argc, char *argv[])\n{\n int fd, perm, uid, gid;\n char *testpath;\n char cmd[PATH_MAX + 20];\n\n testpath \u003d (argc \u003e 1) ? argv[1] : TESTPATH;\n perm \u003d (argc \u003e 2) ? strtoul(argv[2], NULL, 8) : PERM;\n uid \u003d (argc \u003e 3) ? atoi(argv[3]) : UID;\n gid \u003d (argc \u003e 4) ? atoi(argv[4]) : GID;\n\n unlink(testpath);\n\n fd \u003d open(testpath, O_RDWR | O_CREAT, 0);\n if (fd \u003d\u003d -1) errExit(\"open\");\n\n if (fchown(fd, uid, gid) \u003d\u003d -1) errExit(\"fchown\");\n if (fchmod(fd, perm) \u003d\u003d -1) errExit(\"fchmod\");\n close(fd);\n\n snprintf(cmd, sizeof(cmd), \"ls -l %s\", testpath);\n system(cmd);\n\n if (seteuid(uid) \u003d\u003d -1) errExit(\"seteuid\");\n\n accessTest(testpath, 0, \"0\");\n accessTest(testpath, R_OK, \"R_OK\");\n accessTest(testpath, W_OK, \"W_OK\");\n accessTest(testpath, X_OK, \"X_OK\");\n accessTest(testpath, R_OK | W_OK, \"R_OK | W_OK\");\n accessTest(testpath, R_OK | X_OK, \"R_OK | X_OK\");\n accessTest(testpath, W_OK | X_OK, \"W_OK | X_OK\");\n accessTest(testpath, R_OK | W_OK | X_OK, \"R_OK | W_OK | X_OK\");\n\n exit(EXIT_SUCCESS);\n} /* main */\n\nThis can be run against an Ext3 filesystem as well as against an XFS\nfilesystem.

But it might still be possible to access this memory from\nuserspace by other means. An example are PCI cards that advertise not only\nmappable memory but also ioport ranges. On x86 architectures, these can be\naccessed with ioperm, iopl, inb, outb, and friends. Mike Frysinger (CCed)\nreported a similar problem on Blackfin arch where it doesn\u0027t seem to be easy\nto mmap non-cached memory but it can still be accessed from userspace.\n\nThis patch allows kernel drivers to pass information about such ports to\nuserspace. Similar to the existing mem[] array, it adds a port[] array to\nstruct uio_info. Each port range is described by start, size, and porttype.\n\nIf a driver fills in at least one such port range, the UIO core will simply\npass this information to userspace by creating a new directory \"portio\"\nunderneath /sys/class/uio/uioN/. Similar to the \"mem\" directory, it will\ncontain a subdirectory (portX) for each port range given.\n\nNote that UIO simply passes this information to userspace, it performs no\naction whatsoever with this data. It\u0027s userspace\u0027s responsibility to obtain\naccess to these ports and to solve arch dependent issues. The \"porttype\"\nattribute tells userspace what kind of port it is dealing with.\n\nThis mechanism could also be used to give userspace information about GPIOs\nrelated to a device. You frequently find such hardware in embedded devices,\nso I added a UIO_PORT_GPIO definition. I\u0027m not really sure if this is a good\nidea since there are other solutions to this problem, but it won\u0027t hurt much\nanyway.\n\nSigned-off-by: Hans J.
