      "message": "signal/timer/event: signalfd core\n\nThis patch series implements the new signalfd() system call.\n\nI took part of the original Linus code (and you know how badly it can be\nbroken :), and I added even more breakage ;) Signals are fetched from the same\nsignal queue used by the process, so signalfd will compete with standard\nkernel delivery in dequeue_signal().  If you want to reliably fetch signals on\nthe signalfd file, you need to block them with sigprocmask(SIG_BLOCK).  This\nseems to be working fine on my Dual Opteron machine.  I made a quick test\nprogram for it:\n\nhttp://www.xmailserver.org/signafd-test.c\n\nThe signalfd() system call implements signal delivery into a file descriptor\nreceiver.  The signalfd file descriptor if created with the following API:\n\nint signalfd(int ufd, const sigset_t *mask, size_t masksize);\n\nThe \"ufd\" parameter allows to change an existing signalfd sigmask, w/out going\nto close/create cycle (Linus idea).  Use \"ufd\" \u003d\u003d -1 if you want a brand new\nsignalfd file.\n\nThe \"mask\" allows to specify the signal mask of signals that we are interested\nin.  The \"masksize\" parameter is the size of \"mask\".\n\nThe signalfd fd supports the poll(2) and read(2) system calls.  The poll(2)\nwill return POLLIN when signals are available to be dequeued.  As a direct\nconsequence of supporting the Linux poll subsystem, the signalfd fd can use\nused together with epoll(2) too.\n\nThe read(2) system call will return a \"struct signalfd_siginfo\" structure in\nthe userspace supplied buffer.  The return value is the number of bytes copied\nin the supplied buffer, or -1 in case of error.  The read(2) call can also\nreturn 0, in case the sighand structure to which the signalfd was attached,\nhas been orphaned.  The O_NONBLOCK flag is also supported, and read(2) will\nreturn -EAGAIN in case no signal is available.\n\nIf the size of the buffer passed to read(2) is lower than sizeof(struct\nsignalfd_siginfo), -EINVAL is returned.  A read from the signalfd can also\nreturn -ERESTARTSYS in case a signal hits the process.  The format of the\nstruct signalfd_siginfo is, and the valid fields depends of the (-\u003ecode \u0026\n__SI_MASK) value, in the same way a struct siginfo would:\n\nstruct signalfd_siginfo {\n\t__u32 signo;\t/* si_signo */\n\t__s32 err;\t/* si_errno */\n\t__s32 code;\t/* si_code */\n\t__u32 pid;\t/* si_pid */\n\t__u32 uid;\t/* si_uid */\n\t__s32 fd;\t/* si_fd */\n\t__u32 tid;\t/* si_fd */\n\t__u32 band;\t/* si_band */\n\t__u32 overrun;\t/* si_overrun */\n\t__u32 trapno;\t/* si_trapno */\n\t__s32 status;\t/* si_status */\n\t__s32 svint;\t/* si_int */\n\t__u64 svptr;\t/* si_ptr */\n\t__u64 utime;\t/* si_utime */\n\t__u64 stime;\t/* si_stime */\n\t__u64 addr;\t/* si_addr */\n};\n\n[akpm@linux-foundation.org: fix signalfd_copyinfo() on i386]\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
