Caitlin Bestler: recvmmsg now has a struct timespec timeout, that\n  works in the same fashion as the ppoll one.\n\n  If the underlying protocol returns a datagram with MSG_OOB set, this\n  will make recvmmsg return right away with as many datagrams (+ the OOB\n  one) it has received so far.\n\n.

      "message": "reintroduce accept4\n\nIntroduce a new accept4() system call.  The addition of this system call\nmatches analogous changes in 2.6.27 (dup3(), evenfd2(), signalfd4(),\ninotify_init1(), epoll_create1(), pipe2()) which added new system calls\nthat differed from analogous traditional system calls in adding a flags\nargument that can be used to access additional functionality.\n\nThe accept4() system call is exactly the same as accept(), except that\nit adds a flags bit-mask argument.  Two flags are initially implemented.\n(Most of the new system calls in 2.6.27 also had both of these flags.)\n\nSOCK_CLOEXEC causes the close-on-exec (FD_CLOEXEC) flag to be enabled\nfor the new file descriptor returned by accept4().  This is a useful\nsecurity feature to avoid leaking information in a multithreaded\nprogram where one thread is doing an accept() at the same time as\nanother thread is doing a fork() plus exec().  More details here:\nhttp://udrepper.livejournal.com/20407.html \"Secure File Descriptor Handling\",\nUlrich Drepper).\n\nThe other flag is SOCK_NONBLOCK, which causes the O_NONBLOCK flag\nto be enabled on the new open file description created by accept4().\n(This flag is merely a convenience, saving the use of additional calls\nfcntl(F_GETFL) and fcntl (F_SETFL) to achieve the same result.\n\nHere\u0027s a test program.  Works on x86-32.  Should work on x86-64, but\nI (mtk) don\u0027t have a system to hand to test with.\n\nIt tests accept4() with each of the four possible combinations of\nSOCK_CLOEXEC and SOCK_NONBLOCK set/clear in \u0027flags\u0027, and verifies\nthat the appropriate flags are set on the file descriptor/open file\ndescription returned by accept4().\n\nI tested Ulrich\u0027s patch in this thread by applying against 2.6.28-rc2,\nand it passes according to my test program.\n\n/* test_accept4.c\n\n  Copyright (C) 2008, Linux Foundation, written by Michael Kerrisk\n       \u003cmtk.manpages@gmail.com\u003e\n\n  Licensed under the GNU GPLv2 or later.\n*/\n#define _GNU_SOURCE\n#include \u003cunistd.h\u003e\n#include \u003csys/syscall.h\u003e\n#include \u003csys/socket.h\u003e\n#include \u003cnetinet/in.h\u003e\n#include \u003cstdlib.h\u003e\n#include \u003cfcntl.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003cstring.h\u003e\n\n#define PORT_NUM 33333\n\n#define die(msg) do { perror(msg); exit(EXIT_FAILURE); } while (0)\n\n/**********************************************************************/\n\n/* The following is what we need until glibc gets a wrapper for\n  accept4() */\n\n/* Flags for socket(), socketpair(), accept4() */\n#ifndef SOCK_CLOEXEC\n#define SOCK_CLOEXEC    O_CLOEXEC\n#endif\n#ifndef SOCK_NONBLOCK\n#define SOCK_NONBLOCK   O_NONBLOCK\n#endif\n\n#ifdef __x86_64__\n#define SYS_accept4 288\n#elif __i386__\n#define USE_SOCKETCALL 1\n#define SYS_ACCEPT4 18\n#else\n#error \"Sorry -- don\u0027t know the syscall # on this architecture\"\n#endif\n\nstatic int\naccept4(int fd, struct sockaddr *sockaddr, socklen_t *addrlen, int flags)\n{\n   printf(\"Calling accept4(): flags \u003d %x\", flags);\n   if (flags !\u003d 0) {\n       printf(\" (\");\n       if (flags \u0026 SOCK_CLOEXEC)\n           printf(\"SOCK_CLOEXEC\");\n       if ((flags \u0026 SOCK_CLOEXEC) \u0026\u0026 (flags \u0026 SOCK_NONBLOCK))\n           printf(\" \");\n       if (flags \u0026 SOCK_NONBLOCK)\n           printf(\"SOCK_NONBLOCK\");\n       printf(\")\");\n   }\n   printf(\"\\n\");\n\n#if USE_SOCKETCALL\n   long args[6];\n\n   args[0] \u003d fd;\n   args[1] \u003d (long) sockaddr;\n   args[2] \u003d (long) addrlen;\n   args[3] \u003d flags;\n\n   return syscall(SYS_socketcall, SYS_ACCEPT4, args);\n#else\n   return syscall(SYS_accept4, fd, sockaddr, addrlen, flags);\n#endif\n}\n\n/**********************************************************************/\n\nstatic int\ndo_test(int lfd, struct sockaddr_in *conn_addr,\n       int closeonexec_flag, int nonblock_flag)\n{\n   int connfd, acceptfd;\n   int fdf, flf, fdf_pass, flf_pass;\n   struct sockaddr_in claddr;\n   socklen_t addrlen;\n\n   printf(\"\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\\n\");\n\n   connfd \u003d socket(AF_INET, SOCK_STREAM, 0);\n   if (connfd \u003d\u003d -1)\n       die(\"socket\");\n   if (connect(connfd, (struct sockaddr *) conn_addr,\n               sizeof(struct sockaddr_in)) \u003d\u003d -1)\n       die(\"connect\");\n\n   addrlen \u003d sizeof(struct sockaddr_in);\n   acceptfd \u003d accept4(lfd, (struct sockaddr *) \u0026claddr, \u0026addrlen,\n                      closeonexec_flag | nonblock_flag);\n   if (acceptfd \u003d\u003d -1) {\n       perror(\"accept4()\");\n       close(connfd);\n       return 0;\n   }\n\n   fdf \u003d fcntl(acceptfd, F_GETFD);\n   if (fdf \u003d\u003d -1)\n       die(\"fcntl:F_GETFD\");\n   fdf_pass \u003d ((fdf \u0026 FD_CLOEXEC) !\u003d 0) \u003d\u003d\n              ((closeonexec_flag \u0026 SOCK_CLOEXEC) !\u003d 0);\n   printf(\"Close-on-exec flag is %sset (%s); \",\n           (fdf \u0026 FD_CLOEXEC) ?

      "message": "flag parameters: paccept w/out set_restore_sigmask\n\nSome platforms do not have support to restore the signal mask in the\nreturn path from a syscall.  For those platforms syscalls like pselect are\nnot defined at all.  This is, I think, not a good choice for paccept()\nsince paccept() adds more value on top of accept() than just the signal\nmask handling.\n\nTherefore this patch defines a scaled down version of the sys_paccept\nfunction for those platforms.  It returns -EINVAL in case the signal mask\nis non-NULL but behaves the same otherwise.\n\nNote that I explicitly included \u003clinux/thread_info.h\u003e.  I saw that it is\ncurrently included but indirectly two levels down.  There is too much risk\nin relying on this.

      "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.

I have done that more times from 2.6.0\ntime and it gets boring to do same changes again and again.  Linux kernel\ncompiles after changes for i386 and ARM targets.  I have added references to\nsome more files into kernel-api book, I have added some section names as well.\n So please, check that changes do not break something and that categories are\nnot too much skewed.\n\nI have changed kernel-doc to accept \"fastcall\" and \"asmlinkage\" words reserved\nby kernel convention.  Most of the other changes are modifications in the\ncomments to make kernel-doc happy, accept some parameters description and do\nnot bail out on errors.  Changed \u003cpid\u003e to @pid in the description, moved some\n#ifdef before comments to correct function to comments bindings, etc.\n\nYou can see result of the modified documentation build at\n  http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz\n\nSome more sources are ready to be included into kernel-doc generated\ndocumentation.  Sources has been added into kernel-api for now.  Some more\nsection names added and probably some more chaos introduced as result of quick\ncleanup work.\n\nSigned-off-by: Pavel Pisa \u003cpisa@cmp.felk.cvut.cz\u003e\nSigned-off-by: Martin Waitz \u003ctali@admingilde.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
