* Add Debian and Slackware style packaging via alienBrian Behlendorf2010-07-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The long term fix for Debian and Slackware style packaging is to add native support for building these packages. Unfortunately, that is a large chunk of work I don't have time for right now. That said it would be nice to have at least basic packages for these distributions. As a quick short/medium term solution I've settled on using alien to convert the RPM packages to DEB or TGZ style packages. The build system has been updated with the following build targets which will first build RPM packages and then convert them as needed to the target package type: make rpm: Create .rpm packages make deb: Create .deb packages make tgz: Create .tgz packages make pkg: Create the right package type for your distribution The solution comes with lot of caveats and your mileage may vary. But basically the big limitations are that the resulting packages: 1) Will not have the correct dependency information. 2) Will not not include the kernel version in the release. 3) Will not handle all differences between distributions. But the resulting packages should be easy to install and remove from your system and take care of running 'depmod -a' and such. As I said at the top this is not the right long term solution. If any of the upstream distribution maintainers want to jump in and help do this right for their distribution I'd love the help.
* Public Release PrepBrian Behlendorf2010-05-171-25/+25
| | | | | | Updated AUTHORS, COPYING, DISCLAIMER, and INSTALL files. Added standardized headers to all source file to clearly indicate the copyright, license, and to give credit where credit is due.
* Add support for 'make -s' silent buildsBrian Behlendorf2010-03-261-0/+1
| | | | | | | The cleanest way to do this is to set AM_LIBTOOLFLAGS = --silent. However, AM_LIBTOOLFLAGS is not honored by automake-1.9.6-2.1 which is what I have been using. To cleanly handle this I am updating to automake-1.11-3 which is why it looks like there is a lot of churn in the Makefiles.
* Allow spl_config.h to be included by dependant packages (updated)Brian Behlendorf2010-03-221-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | We need dependent packages to be able to include spl_config.h to build properly. This was partially solved in commit 0cbaeb1 by using AH_BOTTOM to #undef common #defines (PACKAGE, VERSION, etc) which autoconf always adds and cannot be easily removed. This solution works as long as the spl_config.h is included before your projects config.h. That turns out to be easier said than done. In particular, this is a problem when your package includes its config.h using the -include gcc option which ensures the first thing included is your config.h. To handle all cases cleanly I have removed the AH_BOTTOM hack and replaced it with an AC_CONFIG_HEADERS command. This command runs immediately after spl_config.h is written and with a little awk-foo it strips the offending #defines from the file. This eliminates the problem entirely and makes header safe for inclusion. Also in this change I have removed the few places in the code where spl_config.h is included. It is now added to the gcc compile line to ensure the config results are always available. Finally, I have also disabled the verbose kernel builds. If you want them back you can always build with 'make V=1'. Since things are working now they don't need to be on by default.
* Simplify rpm build rules, added config/rpm.am.Brian Behlendorf2009-07-011-45/+2
| | | | Distro friendly changes such that the kernel modules are packaged seperately.
* Packaging improvements for RHEL and SLES (part 2)Brian Behlendorf2009-06-161-0/+1
| | | | | | | - Allow checking for exported symbols in both Module.symvers and Module.symvers. My stock SLES kernel ships an objects directory with Module.symvers, yet produces a Module.symvers in the local build directory.
* SLES10 Fixes (part 6)Brian Behlendorf2009-05-201-0/+2
| | | | | | | | | - Prior to 2.6.17 there were no *_pgdat helper functions in mm/mmzone.c. Instead for_each_zone() operated directly on pgdat_list which may or may not have been exported depending on how your kernel was compiled. Now new configure checks determine if you have the helpers or not, and if the needed symbols are exported. If they are not exported then they are dynamically aquired at runtime by kallsyms_lookup_name().
* SLES10 Fixes (part 4):Brian Behlendorf2009-05-201-0/+2
| | | | | | | - Configure check for SLES specific API change to vfs_unlink() and vfs_rename() which added a 'struct vfsmount *' argument. This was for something called the linux-security-module, but it appears that it was never adopted upstream.
* SLES10 Fixes (part 3):Brian Behlendorf2009-05-201-0/+1
| | | | | | - Configure check for mutex_lock_nested(). This function was introduced as part of the mutex validator in 2.6.18, but if it's unavailable then it's safe to fallback to a plain mutex_lock().
* SLES10 Fixes (part 2):Brian Behlendorf2009-05-201-0/+2
| | | | | | | | | | | | | | | | - Configure check, the div64_64() function was renamed to div64_u64() as of 2.6.26. - Configure check, the global_page_state() fuction was introduced in 2.6.18 kernels. The earlier 2.6.16 based SLES10 must not try and use it, thankfully get_zone_counts() is still available. - To simplify debugging poison all symbols aquired dynamically using spl_kallsyms_lookup_name() with SYMBOL_POISON. - Add console messages when the user mode helpers fail. - spl_kmem_init_globals() use bit shifts instead of division. - When the monotonic clock is unavailable __gethrtime() must perform the HZ division as an 'unsigned long long' because the SPL only implements __udivdi3(), and not __divdi3() for 'long long' division on 32-bit arches.
* Allow spl_config.h to be included by dependant packagesBrian Behlendorf2009-03-171-0/+1
| | | | | | | | | | | | | | | | We need dependent packages to be able to include spl_config.h so they can leverage the configure checks the SPL has done. This is important because several of the spl headers need the results of these checks to work properly. Unfortunately, the autoheader build product is always private to a particular build and defined certain common things. (PACKAGE, VERSION, etc). This prevents other packages which also use autoheader from being include because the definitions conflict. To avoid this problem the SPL build system leverage AH_BOTTOM to include a spl_unconfig.h at the botton of the autoheader build product. This custom include undefs all known shared symbols to prevent the confict. This does however mean that those definition are also not availble to the SPL package either. The SPL package therefore uses the equivilant SPL_META_* definitions.
* FC10/i686 Compatibility Update (2.6.27.19-170.2.35.fc10.i686)Brian Behlendorf2009-03-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the interests of portability I have added a FC10/i686 box to my list of development platforms. The hope is this will allow me to keep current with upstream kernel API changes, and at the same time ensure I don't accidentally break x86 support. This patch resolves all remaining issues observed under that environment. 1) SPL_AC_ZONE_STAT_ITEM_FIA autoconf check added. As of 2.6.21 the kernel added a clean API for modules to get the global count for free, inactive, and active pages. The SPL attempts to detect if this API is available and directly map spl_global_page_state() to global_page_state(). If the full API is not available then spl_global_page_state() is implemented as a thin layer to get these values via get_zone_counts() if that symbol is available. 2) New kmem:vmem_size regression test added to validate correct vmem_size() functionality. The test case acquires the current global vmem state, allocates from the vmem region, then verifies the allocation is correctly reflected in the vmem_size() stats. 3) Change splat_kmem_cache_thread_test() to always use KMC_KMEM based memory. On x86 systems with limited virtual address space failures resulted due to exhaustig the address space. The tests really need to problem exhausting all memory on the system thus we need to use the physical address space. 4) Change kmem:slab_lock to cap it's memory usage at availrmem instead of using the native linux nr_free_pages(). This provides additional test coverage of the SPL Linux VM integration. 5) Change kmem:slab_overcommit to perform allocation of 256K instead of 1M. On x86 based systems it is not possible to create a kmem backed slab with entires of that size. To compensate for this the number of allocations performed in increased by 4x. 6) Additional autoconf documentation for proposed upstream API changes to make additional symbols available to modules. 7) Console error messages added when spl_kallsyms_lookup_name() fails to locate an expected symbol. This causes the module to fail to load and we need to know exactly which symbol was not available.
* Added SPL_AC_5ARGS_DEVICE_CREATE autoconf configure checkBrian Behlendorf2009-03-131-0/+1
| | | | | | | As of 2.6.27 kernels the device_create() API changed to include a private data argument. This check detects which version of device_create() function the kernel has and properly defines spl_device_create() to use the correct prototype.
* Build system cleanupBrian Behlendorf2009-03-111-3/+1
| | | | | | 1) Undefine non-unique entries in spl_config.h 2) Minor Makefile cleanup 3) Don't use includedir for proper kernel header install
* Build system and packaging (RPM support)Brian Behlendorf2009-03-091-27/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | An update to the build system to properly support all commonly used Makefile targets these include: make all # Build everything make install # Install everything make clean # Clean up build products make distclean # Clean up everything make dist # Create package tarball make srpm # Create package source RPM make rpm # Create package binary RPMs make tags # Create ctags and etags for everything Extra care was taken to ensure that the source RPMs are fully rebuildable against Fedora/RHEL/Chaos kernels. To build binary RPMs from the source RPM for your system simply run: rpmbuild --rebuild spl-x.y.z-1.src.rpm This will produce two binary RPMs with correct 'requires' dependencies for your kernel. One will contain all spl modules and support utilities, the other is a devel package for compiling additional kernel modules which are dependant on the spl. spl-x.y.z-1_<kernel version>.x86_64.rpm spl-devel-x.y.2-1_<kernel version>.x86_64.rpm
* Linux VM Integration CleanupBrian Behlendorf2009-03-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove all instances of functions being reimplemented in the SPL. When the prototypes are available in the linux headers but the function address itself is not exported use kallsyms_lookup_name() to find the address. The function name itself can them become a define which calls a function pointer. This is preferable to reimplementing the function in the SPL because it ensures we get the correct version of the function for the running kernel. This is actually pretty safe because the prototype is defined in the headers so we know we are calling the function properly. This patch also includes a rhel5 kernel patch we exports the needed symbols so we don't need to use kallsyms_lookup_name(). There are autoconf checks to detect if the symbol is exported and if so to use it directly. We should add patches for stock upstream kernels as needed if for no other reason than so we can easily track which additional symbols we needed exported. Those patches can also be used by anyone willing to rebuild their kernel, but this should not be a requirement. The rhel5 version of the export-symbols patch has been applied to the chaos kernel. Additional fixes: 1) Implement vmem_size() function using get_vmalloc_info() 2) SPL_CHECK_SYMBOL_EXPORT macro updated to use $LINUX_OBJ instead of $LINUX because Module.symvers is a build product. When $LINUX_OBJ != $LINUX we will not properly detect exported symbols. 3) SPL_LINUX_COMPILE_IFELSE macro updated to add include2 and $LINUX/include search paths to allow proper compilation when the kernel target build directory is not the source directory.

* Additional Linux VM integrationBrian Behlendorf2009-02-051-0/+1
| | | | | | | | | | | | | Added support for Solaris swapfs_minfree, and swapfs_reserve tunables. In additional availrmem is now available and return a reasonable value which is reasonably analogous to the Solaris meaning. On linux we return the sun of free and inactive pages since these are all easily reclaimable. All tunables are available in /proc/sys/kernel/spl/vm/* and they may need a little adjusting once we observe the real behavior. Some of the defaults are mapped to similar linux counterparts, others are straight from the OpenSolaris defaults.
* Linux VM integration / device special filesBrian Behlendorf2009-02-041-0/+3
| | | | | | | | | | | | | | Support added to provide reasonable values for the global Solaris VM variables: minfree, desfree, lotsfree, needfree. These values are set to the sum of their per-zone linux counterparts which should be close enough for Solaris consumers. When a non-GPL app links against the SPL we cannot use the udev interfaces, which means non of the device special files are created. Because of this I had added a poor mans udev which cause the SPL to invoke an upcall and create the basic devices when a minor is registered. When a minor is unregistered we use the vnode interface to unlink the special file.
* 2.6.27+ portability changesBrian Behlendorf2009-02-021-0/+1
| | | | | | | | | | | | | | - Added SPL_AC_3ARGS_ON_EACH_CPU configure check to determine if the older 4 argument version of on_each_cpu() should be used or the new 3 argument version. The retry argument was dropped in the new API which was never used anyway. - Updated work queue compatibility wrappers. The old way this worked was to pass a data point when initialized the workqueue. The new API assumed the work item is embedding in a structure and we us container_of() to find that data pointer. - Updated skc->skc_flags to be an unsigned long which is now type checked in the bit operations. This silences the warnings. - Updated autogen products and splat tests accordingly

| | | | | | | | | | | | | | | | | | | at a time as I audit it. This chunk finishes moving the SPL entirely off the linux slab on to the SPL implementation. It differs slightly from the proposed version in that the spl continues to export to all the Solaris types and functions. These do conflict with the Linux slab so a module usings these interfaces must not include the SPL slab if they also intend to use the linux slab. Or they must explcitly #undef the macros which remap the functioin to their spl_* equivilants. A nice side of effect of dropping the entire linux slab is we don't need to autoconf checks anymore. They kept messing with the slab API endlessly! git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@148 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Ensure mutex_init() never fails in the case of ENOMEM by retrying forever. I don't think I've ever seen this happen but it was clear after code inspection that if it did we would immediately crash. 2) Enable full debugging in check.sh for sanity tests. Might as well get as much debug as we can in the case of a failure. 3) Reworked list of kmem caches tracked by SPL in to a hash with the key based on the address of the kmem_cache_t. This should speed up the constructor/destructor/shrinker lookup needed now for newer kernel which removed the destructor support. 4) Updated kmem_cache_create to handle the case where CONFIG_SLUB is defined. The slub would occasionally merge slab caches which resulted in non-unique keys for our hash lookup in 3). To fix this we detect if the slub is enabled and then set the needed flag to prevent this merging from ever occuring. 5) New kernels removed the proc_dir_entry pointer from items registered by sysctl. This means we can no long be sneaky and manually insert things in to the sysctl tree simply by walking the proc tree. So I'm forced to create a seperate tree for all the things I can't easily support via sysctl interface. I don't like it but it will do for now. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@124 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c
