* Illumos 5056 - ZFS deadlock on db_mtx and dn_holdsJustin T. Gibbs2015-04-281-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5056 ZFS deadlock on db_mtx and dn_holds Author: Justin Gibbs <[email protected]> Reviewed by: Will Andrews <[email protected]> Reviewed by: Matt Ahrens <[email protected]> Reviewed by: George Wilson <[email protected]> Approved by: Dan McDonald <[email protected]> References: https://www.illumos.org/issues/5056 https://github.com/illumos/illumos-gate/commit/bc9014e Porting Notes: sa_handle_get_from_db(): - the original patch includes an otherwise unmentioned fix for a possible usage of an uninitialised variable dmu_objset_open_impl(): - Under Illumos list_link_init() is the same as filling a list_node_t with NULLs, so they don't notice if they miss doing list_link_init() on a zero'd containing structure (e.g. allocated with kmem_zalloc as here). Under Linux, not so much: an uninitialised list_node_t goes "Boom!" some time later when it's used or destroyed. dmu_objset_evict_dbufs(): - reduce stack usage using kmem_alloc() Ported-by: Chris Dunlop <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]>

| | | | | | | | | | | | | | | | | | This loop in dmu_objset_write_ready(): for (i = 0; i < dnp->dn_nblkptr; i++) bp->blk_fill += dnp->dn_blkptr[i].blk_fill; invokes _undefined behavior_ for the (common) case of dn_nblkptr=3, therefore, the compiler is free to do whatever it wants (such as optimizing it away, or otherwise messing up your expections).

* Support custom build directories and move includesBrian Behlendorf2010-09-081-0/+329
One of the neat tricks an autoconf style project is capable of is allow configurion/building in a directory other than the source directory. The major advantage to this is that you can build the project various different ways while making changes in a single source tree. For example, this project is designed to work on various different Linux distributions each of which work slightly differently. This means that changes need to verified on each of those supported distributions perferably before the change is committed to the public git repo. Using nfs and custom build directories makes this much easier. I now have a single source tree in nfs mounted on several different systems each running a supported distribution. When I make a change to the source base I suspect may break things I can concurrently build from the same source on all the systems each in their own subdirectory. wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz tar -xzf zfs-x.y.z.tar.gz cd zfs-x-y-z ------------------------- run concurrently ---------------------- <ubuntu system> <fedora system> <debian system> <rhel6 system> mkdir ubuntu mkdir fedora mkdir debian mkdir rhel6 cd ubuntu cd fedora cd debian cd rhel6 ../configure ../configure ../configure ../configure make make make make make check make check make check make check This change also moves many of the include headers from individual incude/sys directories under the modules directory in to a single top level include directory. This has the advantage of making the build rules cleaner and logically it makes a bit more sense.
