On those platforms,\nforce_successful_syscall_return() provides a way to indicate that the\nsystem call return value should not be treated as an error even if it is\nin the range which would normally be taken as a negative error number.\n\nThis adds a force_successful_syscall_return() call to the time() and\ntimes() system calls plus their 32-bit compat versions, so that they don\u0027t\nerroneously indicate an error on those platforms whose system call ABI has\na separate error indication. This will not affect anything on other\nplatforms.\n\nJoakim Tjernlund added the fix for time() and the compat versions of\ntime() and times(), after I did the fix for times().\n\nSigned-off-by: Joakim Tjernlund \u003cJoakim.Tjernlund@transmode.se\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: David S.

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.

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 splits capable() from has_capability() down into the commoncap and\nSELinux code. The capable() security op now only deals with the current\nprocess, and uses the current process\u0027s subjective creds. A new security op -\ntask_capable() - is introduced that can check any task\u0027s objective creds.\n\nstrictly the capable() security op is superfluous with the presence of the\ntask_capable() op, however it should be faster to call the capable() op since\ntwo fewer arguments need be passed down through the various layers.\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.
