      "message": "flag parameters: paccept\n\nThis patch is by far the most complex in the series.  It adds a new syscall\npaccept.  This syscall differs from accept in that it adds (at the userlevel)\ntwo additional parameters:\n\n- a signal mask\n- a flags value\n\nThe flags parameter can be used to set flag like SOCK_CLOEXEC.  This is\nimlpemented here as well.  Some people argued that this is a property which\nshould be inherited from the file desriptor for the server but this is against\nPOSIX.  Additionally, we really want the signal mask parameter as well\n(similar to pselect, ppoll, etc).  So an interface change in inevitable.\n\nThe flag value is the same as for socket and socketpair.  I think diverging\nhere will only create confusion.  Similar to the filesystem interfaces where\nthe use of the O_* constants differs, it is acceptable here.\n\nThe signal mask is handled as for pselect etc.  The mask is temporarily\ninstalled for the thread and removed before the call returns.  I modeled the\ncode after pselect.  If there is a problem it\u0027s likely also in pselect.\n\nFor architectures which use socketcall I maintained this interface instead of\nadding a system call.  The symmetry shouldn\u0027t be broken.\n\nThe following test must be adjusted for architectures other than x86 and\nx86-64 and in case the syscall numbers changed.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n#include \u003cerrno.h\u003e\n#include \u003cfcntl.h\u003e\n#include \u003cpthread.h\u003e\n#include \u003csignal.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003cunistd.h\u003e\n#include \u003cnetinet/in.h\u003e\n#include \u003csys/socket.h\u003e\n#include \u003csys/syscall.h\u003e\n\n#ifndef __NR_paccept\n# ifdef __x86_64__\n#  define __NR_paccept 288\n# elif defined __i386__\n#  define SYS_PACCEPT 18\n#  define USE_SOCKETCALL 1\n# else\n#  error \"need __NR_paccept\"\n# endif\n#endif\n\n#ifdef USE_SOCKETCALL\n# define paccept(fd, addr, addrlen, mask, flags) \\\n  ({ long args[6] \u003d { \\\n       (long) fd, (long) addr, (long) addrlen, (long) mask, 8, (long) flags }; \\\n     syscall (__NR_socketcall, SYS_PACCEPT, args); })\n#else\n# define paccept(fd, addr, addrlen, mask, flags) \\\n  syscall (__NR_paccept, fd, addr, addrlen, mask, 8, flags)\n#endif\n\n#define PORT 57392\n\n#define SOCK_CLOEXEC O_CLOEXEC\n\nstatic pthread_barrier_t b;\n\nstatic void *\ntf (void *arg)\n{\n  pthread_barrier_wait (\u0026b);\n  int s \u003d socket (AF_INET, SOCK_STREAM, 0);\n  struct sockaddr_in sin;\n  sin.sin_family \u003d AF_INET;\n  sin.sin_addr.s_addr \u003d htonl (INADDR_LOOPBACK);\n  sin.sin_port \u003d htons (PORT);\n  connect (s, (const struct sockaddr *) \u0026sin, sizeof (sin));\n  close (s);\n\n  pthread_barrier_wait (\u0026b);\n  s \u003d socket (AF_INET, SOCK_STREAM, 0);\n  sin.sin_port \u003d htons (PORT);\n  connect (s, (const struct sockaddr *) \u0026sin, sizeof (sin));\n  close (s);\n  pthread_barrier_wait (\u0026b);\n\n  pthread_barrier_wait (\u0026b);\n  sleep (2);\n  pthread_kill ((pthread_t) arg, SIGUSR1);\n\n  return NULL;\n}\n\nstatic void\nhandler (int s)\n{\n}\n\nint\nmain (void)\n{\n  pthread_barrier_init (\u0026b, NULL, 2);\n\n  struct sockaddr_in sin;\n  pthread_t th;\n  if (pthread_create (\u0026th, NULL, tf, (void *) pthread_self ()) !\u003d 0)\n    {\n      puts (\"pthread_create failed\");\n      return 1;\n    }\n\n  int s \u003d socket (AF_INET, SOCK_STREAM, 0);\n  int reuse \u003d 1;\n  setsockopt (s, SOL_SOCKET, SO_REUSEADDR, \u0026reuse, sizeof (reuse));\n  sin.sin_family \u003d AF_INET;\n  sin.sin_addr.s_addr \u003d htonl (INADDR_LOOPBACK);\n  sin.sin_port \u003d htons (PORT);\n  bind (s, (struct sockaddr *) \u0026sin, sizeof (sin));\n  listen (s, SOMAXCONN);\n\n  pthread_barrier_wait (\u0026b);\n\n  int s2 \u003d paccept (s, NULL, 0, NULL, 0);\n  if (s2 \u003c 0)\n    {\n      puts (\"paccept(0) failed\");\n      return 1;\n    }\n\n  int coe \u003d fcntl (s2, F_GETFD);\n  if (coe \u0026 FD_CLOEXEC)\n    {\n      puts (\"paccept(0) set close-on-exec-flag\");\n      return 1;\n    }\n  close (s2);\n\n  pthread_barrier_wait (\u0026b);\n\n  s2 \u003d paccept (s, NULL, 0, NULL, SOCK_CLOEXEC);\n  if (s2 \u003c 0)\n    {\n      puts (\"paccept(SOCK_CLOEXEC) failed\");\n      return 1;\n    }\n\n  coe \u003d fcntl (s2, F_GETFD);\n  if ((coe \u0026 FD_CLOEXEC) \u003d\u003d 0)\n    {\n      puts (\"paccept(SOCK_CLOEXEC) does not set close-on-exec flag\");\n      return 1;\n    }\n  close (s2);\n\n  pthread_barrier_wait (\u0026b);\n\n  struct sigaction sa;\n  sa.sa_handler \u003d handler;\n  sa.sa_flags \u003d 0;\n  sigemptyset (\u0026sa.sa_mask);\n  sigaction (SIGUSR1, \u0026sa, NULL);\n\n  sigset_t ss;\n  pthread_sigmask (SIG_SETMASK, NULL, \u0026ss);\n  sigaddset (\u0026ss, SIGUSR1);\n  pthread_sigmask (SIG_SETMASK, \u0026ss, NULL);\n\n  sigdelset (\u0026ss, SIGUSR1);\n  alarm (4);\n  pthread_barrier_wait (\u0026b);\n\n  errno \u003d 0 ;\n  s2 \u003d paccept (s, NULL, 0, \u0026ss, 0);\n  if (s2 !\u003d -1 || errno !\u003d EINTR)\n    {\n      puts (\"paccept did not fail with EINTR\");\n      return 1;\n    }\n\n  close (s);\n\n  puts (\"OK\");\n\n  return 0;\n}\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\n[akpm@linux-foundation.org: make it compile]\n[akpm@linux-foundation.org: add sys_ni stub]\nSigned-off-by: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nAcked-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nCc: \"David S.

      "message": "[AF_UNIX]: Datagram getpeersec\n\nThis patch implements an API whereby an application can determine the\nlabel of its peer\u0027s Unix datagram sockets via the auxiliary data mechanism of\nrecvmsg.\n\nPatch purpose:\n\nThis patch enables a security-aware application to retrieve the\nsecurity context of the peer of a Unix datagram socket.  The application\ncan then use this security context to determine the security context for\nprocessing on behalf of the peer who sent the packet.\n\nPatch design and implementation:\n\nThe design and implementation is very similar to the UDP case for INET\nsockets.  Basically we build upon the existing Unix domain socket API for\nretrieving user credentials.  Linux offers the API for obtaining user\ncredentials via ancillary messages (i.e., out of band/control messages\nthat are bundled together with a normal message).  To retrieve the security\ncontext, the application first indicates to the kernel such desire by\nsetting the SO_PASSSEC option via getsockopt.  Then the application\nretrieves the security context using the auxiliary data mechanism.\n\nAn example server application for Unix datagram socket should look like this:\n\ntoggle \u003d 1;\ntoggle_len \u003d sizeof(toggle);\n\nsetsockopt(sockfd, SOL_SOCKET, SO_PASSSEC, \u0026toggle, \u0026toggle_len);\nrecvmsg(sockfd, \u0026msg_hdr, 0);\nif (msg_hdr.msg_controllen \u003e sizeof(struct cmsghdr)) {\n    cmsg_hdr \u003d CMSG_FIRSTHDR(\u0026msg_hdr);\n    if (cmsg_hdr-\u003ecmsg_len \u003c\u003d CMSG_LEN(sizeof(scontext)) \u0026\u0026\n        cmsg_hdr-\u003ecmsg_level \u003d\u003d SOL_SOCKET \u0026\u0026\n        cmsg_hdr-\u003ecmsg_type \u003d\u003d SCM_SECURITY) {\n        memcpy(\u0026scontext, CMSG_DATA(cmsg_hdr), sizeof(scontext));\n    }\n}\n\nsock_setsockopt is enhanced with a new socket option SOCK_PASSSEC to allow\na server socket to receive security context of the peer.\n\nTesting:\n\nWe have tested the patch by setting up Unix datagram client and server\napplications.  We verified that the server can retrieve the security context\nusing the auxiliary data mechanism of recvmsg.\n\nSigned-off-by: Catherine Zhang \u003ccxzhang@watson.ibm.com\u003e\nAcked-by: Acked-by: James Morris \u003cjmorris@namei.org\u003e\nSigned-off-by: David S.
