* mdmon: satisfy glibc tls abi requirements with pthreadsDan Williams2010-07-061-3/+11
| | | | | | | | | | | | | Setting up a proper tls descriptor is required to conform to the abi [1]. Until it can be implemented in mdmon use pthreads instead of clone(2) to let glibc handle the details. The old behaviour can be had by un-defining USE_PTHREADS. Note, the "O2" builds need LDFLAGS now to pick up the '-pthread' option. [1]: http://people.redhat.com/drepper/tls.pdf Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* mdmon: prevent allocations due to late bindingDan Williams2010-07-011-1/+2
| | | | | | | | | | | | | | | | Current versions of glibc do not provide a useable interface to clone(2) as it inflicts hidden dependencies on setting up a glibc specific tls descriptor. The dynamic linker trips this dependency and causes mdmon to intermittently fail to load. Resolving all dynamic linking prior to starting the monitor thread appears to mitigate the issue but there is no guarantee that another tls dependency will bite us later. However, while the debate continues with the glibc maintainers it seems prudent to keep this change. It ensures that we do not get into a situation where the monitor thread needs to make a late allocation to resolve a symbol. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* Compile-time switch to enable 0.9 metadata as defaultmartin f. krafft2010-05-311-2/+11
| | | | | | | | | | | | | | | | | | | | | | This commit introduces DEFAULT_OLD_METADATA as a preprocessor definition. If defined, it causes mdadm to assume metadata version 0.9 as default. If not defined, version 1.x (currently 1.2) is used as default. The man page mdadm.8 is also modified to reflect the chosen default. The selftests will not work if the old default is chosen. This patch was requested by Debian so they could distribute a current mdadm together with boot loaders that only understand 0.90 metadata for md-raid. Preferred usage is simply make DEFAULT_OLD_METADATA=yes Signed-off-by: martin f. krafft <madduck@debian.org> Signed-off-by: NeilBrown <neilb@suse.de>
