2016-01-08linux-user: SOCK_PACKET uses network endian to encode protocol in socket()Laurent Vivier1-0/+6
in PACKET(7) : packet_socket = socket(AF_PACKET, int socket_type, int protocol); [...] protocol is the IEEE 802.3 protocol number in network order. See the <linux/if_ether.h> include file for a list of allowed protocols. When protocol is set to htons(ETH_P_ALL) then all protocols are received. All incoming packets of that protocol type will be passed to the packet socket before they are passed to the protocols implemented in the kernel. [...] Compatibility In Linux 2.0, the only way to get a packet socket was by calling socket(AF_INET, SOCK_PACKET, protocol). We need to tswap16() the protocol because on big-endian, the ABI is waiting for, for instance for ETH_P_ALL, 0x0003 (big endian == network order), whereas on little-endian it is waiting for 0x0300.

2016-01-08linux-user: correctly align target_epoll_eventLaurent Vivier1-8/+11
According to comments in /usr/include/linux/eventpoll.h, poll_event is packed only on x86_64. And to be sure fields are correctly aligned in epoll_data, use abi_XXX types for all of them. Moreover, fd type is wrong: fd is int, not ulong. This has been tested with a ppc guest on an x86_64 host: without this patch, systemd crashes (core).

2016-01-08linux-user: add signalfd/signalfd4 syscallsLaurent Vivier1-0/+167
This patch introduces a system very similar to the one used in the kernel to attach specific functions to a given file descriptor. In this case, we attach a specific "host_to_target()" translator to the fd returned by signalfd() to be able to byte-swap the signalfd_siginfo structure provided by read(). This patch allows to execute the example program given by man signalfd(2): #include <sys/signalfd.h> #include <signal.h> #include <unistd.h> #include <stdlib.h> #include <stdio.h> #define handle_error(msg) \ do { perror(msg); exit(EXIT_FAILURE); } while (0) int main(int argc, char *argv[]) { sigset_t mask; int sfd; struct signalfd_siginfo fdsi; ssize_t s; sigemptyset(&mask); sigaddset(&mask, SIGINT); sigaddset(&mask, SIGQUIT); /* Block signals so that they aren't handled according to their default dispositions */ if (sigprocmask(SIG_BLOCK, &mask, NULL) == -1) handle_error("sigprocmask"); sfd = signalfd(-1, &mask, 0); if (sfd == -1) handle_error("signalfd"); for (;;) { s = read(sfd, &fdsi, sizeof(struct signalfd_siginfo)); if (s != sizeof(struct signalfd_siginfo)) handle_error("read"); if (fdsi.ssi_signo == SIGINT) { printf("Got SIGINT\n"); } else if (fdsi.ssi_signo == SIGQUIT) { printf("Got SIGQUIT\n"); exit(EXIT_SUCCESS); } else { printf("Read unexpected signal\n"); } } } $ ./signalfd_demo ^CGot SIGINT ^CGot SIGINT ^\Got SIGQUIT Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2015-12-23io: fix stack allocation when sending of file descriptorsDaniel P. Berrange2-4/+99
When sending file descriptors over a socket, we have to allocate a data buffer to hold the FDs in the scmsghdr. Unfortunately we allocated the buffer on the stack inside an if () {} block, but called sendmsg() outside the block. So the stack bytes holding the FDs were liable to be overwritten with other data. By luck this was not a problem when sending 1 FD, but if sending 2 or more then it would fail. The fix is to simply move the variables outside the nested 'if' block. To keep valgrind quiet we also zero-initialize the 'control' buffer. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2015-12-23virtio-9p: use accessor to get thread_poolGreg Kurz1-1/+1

It is hence forbidden to access the thread_pool field directly, as it may be NULL. The accessor *must* be used always.
