| * atomic: implement atomic operations based on gcc's __sync extensionLennart Poettering2009-05-201-24/+5
| | | | | | | | | | | | | | | | | | | | | | Newer gccs and intel ccs support a __sync extension for making use of atomic operations. This patch replaces the handcrafted x86 atomic operation support with usage of __sync. __sync is supported by more processors and by more compilers than the old assembler code. Also, this extension has been available on gcc for quite a while now for x86, so replacing the old assembler code should only be a loss when very old compiilers are used.
| * memset: replace memset() by _DBUS_ZERO where applicableLennart Poettering2009-05-201-4/+4
| |
| * cloexec: set all sockets that are created with SOCK_CLOEXECLennart Poettering2009-05-201-5/+57
| | | | | | | | | | | | Since all socket users enable FD_CLOEXEC anyway we can just do that in _dbus_open_socket() and be done with it for all cases. By side effect this allows us to use SOCK_CLOEXEC and hence close the CLOEXEC race.
| * build-system: define _GNU_SOURCE centrallyLennart Poettering2009-05-201-1/+1
| | | | | | | | | | Instead of having everyone define _GNU_SOURCE and similar macros seperately, simply do so centrally by using AC_USE_SYSTEM_EXTENSIONS
| * cloexec: set FD_CLOEXEC for all full duplex pipesLennart Poettering2009-05-201-3/+26
| | | | | | | | | | | | | | All users of full duplex pipes enable FD_CLOEXEC later anyway so let's just do it as part of _dbus_full_duplex_pipe. By side effect this allows to make use of SOCK_CLOEXEC which fixes a race when forking/execing from a different thread at the same time as we ar in this function.
| * sysdeps-unix: add basic IO primitives for unix fd passingLennart Poettering2009-05-201-1/+236
| | | | | | | | | | | | | | | | | | | | | | | | This introduces three new functions: _dbus_read_socket_with_unix_fds _dbus_write_socket_with_unix_fds _dbus_read_socket_with_unix_fds_two These work exactly like their counterpart sans 'with_unix_fds' except that they also send/recieve file descriptors along with the actual payload data.
| * sysdeps-unix: introduce _dbus_socket_can_pass_unix_fd()Lennart Poettering2009-05-201-0/+32
| | | | | | | | | | | | This function can be used to check if a socket can be used to pass file descriptors. On platforms that don't support this at all this is hardcoded to return FALSE.
| * sysdeps-unix: introduce _dbus_dup()Lennart Poettering2009-05-201-0/+42
| | | | | | | | | | | | | | This is a simple wrapper around dup()-like functionality. Also handles CLOEXEC and makes sure we don't interfere with the standard I/O file descriptors 0, 1 and 2.
| * sysdeps-unix: Use MSG_NOSIGNAL when availableLennart Poettering2009-05-151-0/+61
| | | | | | | | | | | | | | | | | | On Linux send()/sendmsg() know the special flag MSG_NOSIGNAL which if set makes sure that no SIGPIPE signal is raised when we write to a socket that has been disconnected. By using this flag we don't have to play games with SIGPIPE which is pretty ugly stuff since it touches the global process context.
* | Cope with dbus-launch not being in DBUS_BINDIRColin Walters2009-07-141-11/+19
| | | | | | | | | | | | | | | | | | This is a temporary hack for systems which use DBUS_BINDIR=/bin, but then move dbus-launch back into /usr/bin. Longer term, we should explicitly support this in upstream code, or even better figure out how to move dbus-launch into /bin (e.g. dynamically load libX11 if available), or have a --with-x11-tools configure option.
* | Bug 19432 - Fix handling of HAVE_CMSGCRED case (FreeBSD)Hasso Tepper2009-07-131-15/+19
| | | | | | | | | | | | | | | | Fixes dbus on FreeBSD and DragonFly systems. The patch is obtained from FreeBSD ports tree. Signed-off-by: Colin Walters <walters@verbum.org>
* | Bug 14259 - Refactor _dbus_get_autolaunch_addressColin Walters2009-07-131-70/+114
| | | | | | | | | | | | Split out the process-launching code, which can be reused for other applications; in particular, a forthcoming patch to parse output from launchd for MacOS X.
* | Bug 14259 - Make session address lookup system-dependentColin Walters2009-07-131-0/+31
| | | | | | | | | | | | | | On some platforms such as MacOS X and Windows, we can't depend on an environment variable to determine the address of the session bus. Create a sysdep function dbus_lookup_session_address which can be filled in with platform-specific code.
* | Bug 14259 - Work around broken getgrouplist on MacOS XBenjamin Reed2009-07-131-11/+39
| | | | | | | | | | | | | | We don't get the number of groups, so allocate an arbitrary larger array. Signed-off-by: Colin Walters <walters@space-ghost.verbum.org>

* | Bug 21347 - Don't fail autolaunching if process has SIGCHLD handlerKurt Miller2009-07-101-0/+13
|/ | | | | | | | | If other code in the process set a global SIGCHLD handler, it will make autolaunching fail spuriously due to waitpid() failing. This fix will temporarily block SIGCHLD delivery. Signed-off-by: Colin Walters <walters@verbum.org>

* Bug 16755: Ensure we use the correct errnoTor Lillqvist2008-09-181-11/+17
| | | | | | | | * dbus/dbus-sysdeps-unix.c: Save errno across cleanup and use it for errors to ensure we display the right error message. Signed-off-by: Colin Walters <walters@verbum.org>

| | | | | | | | | * dbus/dbus-sysdeps-unix.c: * dbus/dbus-sysdeps-util-unix.c: Cast return from sysconf temporarily so we actually see -1. Signed-off-by: Colin Walters <walters@verbum.org>
* Bug 17352: synchronize the file before renamingArtem Bityutskiy2008-09-041-0/+9
| | | | | | | | | | | | | | Dbus is doing atomic file updates by copying them, changing the copy, and re-naming them. However, it does not synchronize the file before re-naming, which results in corruption in case of unclean reboots. The reason for this is that file-systems have write-back cache and they postpone writing data to the media. This patch adds the missed fsync() for the Unix part. I do not have windows so cannot provide a windows port fix. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: Colin Walters <walters@verbum.org>

* Bug 16727: Handle ERANGE for getgr; fixes user in many groupsMarc Brockschmidt2008-07-281-15/+50
| | | | | | | | | | Patch originally from Noèl Köthe. Modified by Colin Walters <walters@verbum.org> * dbus/dbus-sysdeps-unix.c, dbus/dbus-sysdeps-unix-utils.c: Use a while() loop to reallocate buffer if we get ERANGE return. This fixes the case where a user is in a large number of groups.

* Fix detection of i486 atomic ops.Simon McVittie2007-10-111-3/+3
| | | | | | Previously, the attempts to determine support at compile-time on Darwin were causing the i486 atomic ops to be used on *all* i386 or x86-64 GCC builds (AH_VERBATIM can't be conditionalized like we were trying to).

These should be seporate, as there may be a security issue starting up some session stuff as root. The use-case for the same binary starting up per-system _and_ per-session is also not valid.
