2022-09-26Remove the slirp submodule (i.e. compile only with an external libslirp)Thomas Huth1-0/+0
Since QEMU 7.1 we don't support Ubuntu 18.04 anymore, so the last big important Linux distro that did not have a pre-packaged libslirp has been dismissed. All other major distros seem to have a libslirp package in their distribution already - according to repology.org: Fedora 35: 4.6.1 CentOS 8 (RHEL-8): 4.4.0 Debian 11: 4.4.0 OpenSUSE Leap 15.3: 4.3.1 Ubuntu LTS 20.04: 4.1.0 FreeBSD Ports: 4.7.0 NetBSD pkgsrc: 4.7.0 Homebrew: 4.7.0 MSYS2 mingw: 4.7.0 The only one that was still missing a libslirp package is OpenBSD - but the next version (OpenBSD 7.2 which will be shipped in October) is going to include a libslirp package. Since QEMU 7.2 will be published after OpenBSD 7.2, we should be fine there, too. So there is no real urgent need for keeping the slirp submodule in the QEMU tree anymore. Thus let's drop the slirp submodule now and rely on the libslirp packages from the distributions instead.

2019-02-12slirp: remove slirp_ prefix for socket wrappersMarc-André Lureau1-7/+7
QEMU wraps the socket functions in os-win32.h, but in commit a9d8b3ec4385793815d71217857304, the header inclusion was dropped, breaking libslirp on Windows. There are already a few socket functions that are wrapped in libslirp, with "slirp_" prefix, but many of them are missing, and we are going to wrap the missing functions in a second patch. Using "slirp_" prefix avoids the conflict with socket function #define wrappers in QEMU os-win32.h, but they are quite intrusive. In the end, the functions should behave the same as original one, but with errno being set. To avoid the churn, and potential confusion, remove the "slirp_" prefix. A series of #undef is necessary until libslirp is made standalone to prevent the #define conflict with QEMU.

Factor out socket pair creation, to simplify the fork_exec() code.

2018-11-10slirp: fork_exec(): create and connect child socket before fork()Peter Maydell1-21/+34
Currently fork_exec() fork()s, and then creates and connects the child socket which it uses for communication with the parent in the child process. This is awkward because the child has no mechanism to report failure back to the parent, which might end up blocked forever in accept(). The child code also has an issue pointed out by Coverity (CID 1005727), where if the qemu_socket() call fails it will pass -1 as a file descriptor to connect(). Fix these issues by moving the creation of the child's end of the socket to before the fork(), where we are in a position to handle a possible failure.

2014-04-25slirp: Remove default_mon usageCole Robinson1-11/+2
These errors don't seem user initiated, so forcibly printing to the monitor doesn't seem right. Just use error_report. Drop lprint since it's now unused.

2013-10-02slirp: call socket_set_fast_reuse instead of setting SO_REUSEADDRSebastian Ottlik1-2/+1
SO_REUSEADDR should be avoided on Windows but is desired on other operating systems. So instead of setting it we call socket_set_fast_reuse that will result in the appropriate behaviour on all operating systems.

2013-08-22aio / timers: Untangle include filesAlex Bligh1-0/+1
include/qemu/timer.h has no need to include main-loop.h and doing so causes an issue for the next patch. Unfortunately various files assume including timers.h will pull in main-loop.h. Untangle this mess. Signed-off-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

The fcntl(fd, F_SETFL, O_NONBLOCK) flag is not specific to sockets. Rename to qemu_set_nonblock() just like qemu_set_cloexec(). Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

Instead of adding missing type casts which are needed by MinGW for the 4th argument, the patch uses qemu_setsockopt which was invented for this purpose. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
