* usermodehelper: Tidy up waitingJeremy Fitzhardinge2007-07-181-3/+9
| | | | | | | | | | | | | | | | | | | | | | | Rather than using a tri-state integer for the wait flag in call_usermodehelper_exec, define a proper enum, and use that. I've preserved the integer values so that any callers I've missed should still work OK.

* usermodehelper: split setup from executionJeremy Fitzhardinge2007-07-181-3/+41
| | | | | | | | | | | | | | | | | | | | | Rather than having hundreds of variations of call_usermodehelper for various pieces of usermode state which could be set up, split the info allocation and initialization from the actual process execution. This means the general pattern becomes: info = call_usermodehelper_setup(path, argv, envp); /* basic state */ call_usermodehelper_<SET EXTRA STATE>(info, stuff...); /* extra state */ call_usermodehelper_exec(info, wait); /* run process and free info */ This patch introduces wrappers for all the existing calling styles for call_usermodehelper_*, but folds their implementations into one.

* Revert "Driver core: let request_module() send a /sys/modules/kmod/-uevent"Greg Kroah-Hartman2007-02-231-2/+0
| | | | | | | | | | | This reverts commit c353c3fb0700a3c17ea2b0237710a184232ccd7f. It turns out that we end up with a loop trying to load the unix module and calling netfilter to do that. Will redo the patch later to not have this loop. Acked-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: let request_module() send a /sys/modules/kmod/-ueventKay Sievers2007-02-161-0/+2
| | | | | | | | | | | | | | | On recent systems, calls to /sbin/modprobe are handled by udev depending on the kind of device the kernel has discovered. This patch creates an uevent for the kernels internal request_module(), to let udev take control over the request, instead of forking the binary directly by the kernel. The direct execution of /sbin/modprobe can be disabled by setting: /sys/module/kmod/mod_request_helper (/proc/sys/kernel/modprobe) to an empty string, the same way /proc/sys/kernel/hotplug is disabled on an udev system.

* [PATCH] Create call_usermodehelper_pipe()Andi Kleen2006-10-011-0/+4
| | | | | | | | | | | | A new member in the ever growing family of call_usermode* functions is born. The new call_usermodehelper_pipe() function allows to pipe data to the stdin of the called user mode progam and behaves otherwise like the normal call_usermodehelp() (except that it always waits for the child to finish) Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Keys: Pass session keyring to call_usermodehelper()David Howells2005-06-241-1/+12
| | | | | | | | | | | The attached patch makes it possible to pass a session keyring through to the process spawned by call_usermodehelper(). This allows patch 3/3 to pass an authorisation key through to /sbin/request-key, thus permitting better access controls when doing just-in-time key creation.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
