drivers/ipc: fix potential race in select()

Acquiring the poll state and binding the selector must be done
atomically, so that such state does not change before xnselect_bind()
decides whether the caller should wait.

[Xenomai-git] Philippe Gerum : boilerplate: allow for auto-init of external shared libraries

2016-09-11 Thread git repository hosting

http://git.xenomai.org/?p=xenomai-3.git;a=commit;h=21845c9cc173283840245927031cc7e40da1c429

boilerplate: allow for auto-init of external shared libraries

3rd-party shared libraries for which Xenomai auto-initialization is
required must include a position-independent version of the bootstrap
module.

This means that we need to export a PIC object such libraries can
include, in addition to a non-PIC object to be linked in regular
executables as usual. Such objects are available as
@libdir@/xenomai/bootstrap-pic.o and @libdir@/xenomai/bootstrap.o
respectively.

xeno-config* scripts now accept the --auto-init-solib option to emit
the proper link directives for including the PIC bootstrap module into
shared libraries when --ldflags is given.

[Xenomai-git] Philippe Gerum : drivers/ipc: fix potential race in select()

drivers/ipc: fix potential race in select()

Acquiring the poll state and binding the selector must be done
atomically, so that such state does not change before xnselect_bind()
decides whether the caller should wait.
