3 | * : Tag spl-0.4.9 | |
4 | ||
5 | * : Build system improvements: | |
6 | - Added support for the 'make -s' silent build option. | |
7 | - Allow spl_config.h to be included by dependant packages. | |
8 | ||
9 | * AUTHORS, COPYING, DISCLAIMER, and INSTALL: Updated. | |
10 | ||
11 | * *.c, *.h, *.sh, AUTHORS, COPYING, DISCLAIMER, and INSTALL: | |
12 | Added standard header to source files which includes the copyright, | |
13 | license, and author information. Additionally, updated the listed | |
14 | top level files to the latest versions. | |
15 | ||
16 | * include/sys/processor.h, include/sys/systm.h, include/sys/types.h: | |
17 | Added 3 missing typedefs processorid_t, pc_t, and index_t. | |
18 | ||
19 | * include/sys/console.h: Added support for console_* functions(). | |
20 | ||
21 | * module/spl/spl-time.c: Updated gethrtime() to use the function | |
22 | do_posix_clock_monotonic_gettime() as described in the comment. | |
23 | ||
24 | * module/spl/spl-condvar.c: Added cv_wait_interruptible() function | |
25 | as an extension to the existing condition variable ABI to enable | |
26 | sleeping threads a way to cleanly handle signals in the kernel. | |
27 | ||
28 | * module/spl/spl-debug.c: Dump log from current process as required. | |
29 | ||
30 | * module/spl/spl-taskq.c: Assume TQ_SLEEP in taskq_dispatch() if | |
31 | the caller does not specify, this is the Solaris default. | |
32 | ||
33 | * module/spl/spl-vnode.c: Extend the vn_rdwr() implementation to | |
34 | correctly handle the FAPPEND option. | |
35 | ||
36 | * module/spl/spl-generic.c, module/spl/spl-vnode.c: Update | |
37 | vn_set_pwd() to allow a kernal address as filename. This turns | |
38 | out to be critical because spl_setup()->The vn_set_pwd("/") which | |
39 | is called at module load time was failing with -EFAULT. | |
40 | ||
41 | * include/sys/rwlock.h: Disable rw_tryupgrade() for kernels built | |
42 | without CONFIG_RWSEM_GENERIC_SPINLOCK defined. The existing | |
43 | implementation is not safe in this case and needs to be replaced | |
44 | with a correct native per-arch implementation. | |
45 | ||
46 | * module/spl/spl-kmem.c: Reduce maximum kmem based slab size. | |
47 | Allowing MAX_ORDER-1 sized memory allocations while the system | |
48 | is low on memory has been observed to result in deadlocks. Callers | |
49 | should not be using the slab in this way but we should still handle | |
50 | the case more cleanly. | |

54 | * : Tag spl-0.4.8 | |
55 | ||
56 | * : Build system improvements: | |
57 | - Remove Module.markers and Module.symver{s} in clean target. | |
58 | - Improved kernel source detection when none specified. | |
59 | - Fix RPM definitions for the unknown distro/installation. | |
60 | ||
61 | * config/spl-build.m4: Linux 2.6.32 compat, SPL_AC_5ARGS_PROC_HANDLER | |
62 | macro added to handle updated proc_handler () API. | |
63 | ||
64 | * module/spl/spl-err.c: Fix panic() string, which was being used as a | |
65 | format string, instead of an already-formatted string. | |
66 | ||
67 | * /module/spl/spl-taskq.c: Optimize lowest outstanding taskqid | |
68 | calculation in taskq_lowest_id(). The motivation for this change | |
69 | was that I was observing as much as 10% of the total CPU time go | |
70 | to waiting on the tq->tq_lock when the pending list was long. | |
71 | ||
72 | * module/spl/spl-kmem.c: Strip __GFP_ZERO from kmalloc it is not | |
73 | available for older kernels. | |
74 | ||
75 | * module/spl/spl-proc.c: Add skc_flags and full header to | |
76 | /proc/spl/kmem/slab | |
77 | ||
78 | * module/spl/spl-generic.c: Correctly handle division on 32-bit RHEL5 | |
79 | systems by returning dividend. | |
80 | ||
81 | * include/sys/rwlock.h: When using x86 specific rwsem correctly | |
82 | intepret rwsem->count. Additionally check for changed guard macro | |
83 | in 2.6.28+ for rwsem implementation | |
84 | ||
85 | * module/splat/splat-vnode.c, module/splat/splat-kmem.c, | |
86 | module/splat/splat-taskq.c: Several new tests were added to the | |
87 | test suite and various bug fixes. | |
88 | ||
89 | * include/asm/atomic_compat.h: Atomic64 compatibility for 32-bit | |
90 | systems without kernel support. | |
91 | ||
92 | * .gitignore: Added .gitignore files. | |

96 | * : Tag spl-0.4.7 | |
97 | ||
98 | * config/spl-build.m4: Linux 2.6.31 compat, SPL_AC_2ARGS_SET_FS_PWD | |
99 | macro updated to explicitly include linux/fs_struct.h which was | |
100 | dropped from linux/sched.h. | |
101 | ||
102 | * include/linux/mm_compat.h: Linux 2.6.31 compat, use the macros | |
103 | min_wmark_pages, low_wmark_pages, and high_wmark_pages which were | |
104 | introduced. For older kernels a compability macro is used. | |
105 | ||
106 | * include/sys/kmem.h: Linux 2.6.31 compat, the __GFP_NOFAIL flag | |
107 | should no longer be used and it may disappear from the kernel at any | |
108 | time. To handle this I have simply added *_nofail wrappers in the | |
109 | kmem implementation which perform the retry for non-atomic allocations. | |
110 | ||
111 | * module/spl/spl-kmem.c: Linux 2.6.31 compat, kmem cache alignment | |
112 | fixes and cleanup. Always perform allocations for the kmem cache | |
113 | using __get_free_pages() or __vmalloc() to ensure the returned | |
114 | memory is page aligned. Also introduce helper functions which use | |
115 | P2ROUNDUP_TYPE instead of P2ROUNDUP force all types to be explicit. | |
116 | ||
117 | * include/sys/mutex.h: Add mutex_enter_nested() as wrapper for | |
118 | mutex_lock_nested() to permit integration with the lock checker. | |
119 | ||
120 | * include/sys/mutex.h: Always use the generic mutex_destroy(). | |
121 | ||
122 | * Makefile.am: Ensure *.order and *.markers build products are | |
123 | removed by distclean rule. | |

126 | ||
127 | * : Tag spl-0.4.6 | |
128 | ||
129 | * config/spl-build.m4: Cleanup --enable-debug-* configure options. | |
130 | --enable-debug=<default no> generic debug support. | |
131 | --enable-debug-kmem=<default yes> basic kmem and slab accounting. | |
132 | --enable-debug-kmem-tracking=<default no> detailed kmem tracking. | |
133 | --enable-debug-kstat removed option support always enabled. | |
134 | --enable-debug-callb removed option which never did anything. | |
135 | ||
136 | * module/spl/spl-atomic.c: Reimplemented atomic functions by | |
137 | layering them on top of the Linux atomic functions. This improves | |
138 | performance by removing the need for a global spinlock. | |
139 | ||
140 | * module/spl/spl-debug.c: Rebase cmn_err on vcmn_err. Handle the | |
141 | case where the message contains a leading ! which means only send | |
142 | it to syslog. And suppress warnings for messages which do not end | |
143 | in a '\n'. | |
144 | ||
145 | * module/splat/splat-ctl.c: Update to use kobject_set_name() for | |
146 | increased portability. | |
147 | ||
148 | * module/spl/spl-generic.c: Set cwd to '/' for the task during | |
149 | module load for SPL dependent modules. Under Solaris this is | |
150 | the expected behavior, on a Linux system your cwd remains set | |
151 | to whatever the tasks cwd was when loading a module. | |
152 | ||
153 | * module/spl/spl-mutex.c: Reimplemented mutexs for improved | |
154 | performance and cleaner integration with the Linux kernels built | |
155 | in lock analyzer. As of 2.6.29 based kernels adaptive mutexs | |
156 | are supported, for these newer kernels task_curr() does not need | |
157 | to be exported. Finally, DEBUG_MUTEX support was dropped in | |
158 | favor of more detailed kernel profiling which is now available. | |
159 | ||
160 | * module/spl/spl-rwlock.c: Reimplemented rwlocks for improved | |
161 | performance and cleaner integration with the Linux kernels built | |
162 | in lock analyzer. Additionally, the rwlock regression tests were | |
163 | improved to help validate correctness. | |
164 | ||
165 | * spl-modules.spec.in: Various spec file tweaks for the supported | |
166 | distros: RHEL5, RHEL6, SLES10, SLES11, Chaos4, Fedora 11. | |
167 | ||

168 | 2009-08-04 Brian Behlendorf <behlendorf1@llnl.gov> |
169 | ||
170 | * : Tag spl-0.4.5 | |
171 | ||
172 | * FC11 and SLES11 support: This includes all compatibility changes | |
173 | to support 2.6.29 based kernels and the required build system | |
174 | improvements. | |
175 | * module/spl/spl-module.c: Register a basic compat ioctl handler | |
176 | for 32-bit user vs 64-bit kernel compatibility. This is the default | |
177 | build environment for all 64-bit SLES systems. | |
178 | * config/spl-build.m4: Check arch/default path when detecting kernel | |
179 | objects under SLES. We still preferentially use arch/arch if | |
180 | available but if that fails it is acceptable to use default. | |
181 | * module/spl/spl-vnode.: Use HAVE_PATH_IN_NAMEIDATA compat macros | |
182 | for maximum kernel compatibility. | |
183 | * config/spl-build.m4: Remove LINUXINCLUDE from autoconf wrapper. | |
184 | This breaks the 2.6.28+ kernels build system, all kernel build systems | |
185 | at least post 2.6.16 will set this properly so we should not. | |
186 | * include/sys/vmsystm.h, module/spl/spl-kmem.c: Perferentially use the | |
187 | global_page_state() API when your kernel supports the required enums. | |
188 | * include/sys/debug.h: Add ASSERTV macro to simplify removing | |
189 | variables (the V in ASSERTV) which are only used in ASSERT(). | |
190 | * include/sys/debug.h: Disable stack overflow checking by default | |
191 | when build with --enable-debug, modern kernels now provide this. | |
192 | * patches/fc11-spl-export-symbols.patch: Recommended missing symbols | |
193 | patch for FC11. This is not required for correct functionality but | |
194 | it is recommended for individuals who are already patching the kernel. | |
195 | ||
196 | * Additional Solaris API emulation: | |
197 | * include/sys/taskq.h: Add basic taskq support for the flag | |
198 | TASKQ_THREADS_CPU_PCT which is used to scale the number of threads | |
199 | based on the number of online CPUs. | |
200 | * include/sys/file.hi, module/spl/spl-generic.c: Add support for | |
201 | fake ioctls which originate from the kernel instead of user space. | |
202 | * include/sys/acl.h: Add ACE_ALL_PERMS ACL definition. | |
203 | * include/sys/cred.h, module/splat/splat-cred.c: Add basic credential | |
204 | support and splat regression tests. | |
205 | ||
206 | * Bug fixes: | |
207 | * include/sys/isa_defs.h: Add more endianess paranoia. | |
208 | * module/spl/spl-time.c: Integer overflow after ~164 days. | |
209 | * include/sys/debug.h: NULL dereference by tcd_for_each(). | |
210 | * module/splat/splat-kmem.c: Allow kmem or vmem based slabs for | |
211 | slab_lock and slab_overcommit tests. This may still be an issue on | |
212 | 32-bit systems due to the small virtual address space. | |
213 | * module/spl/spl-module.c: Positive Solaris ioctl return codes are | |
214 | need to be negated for use by libc to ensure errno is set correctly. | |

218 | * : Tag spl-0.4.4 | |
219 | ||
aaad2f72 | 220 | * : Generic distro friendly build system / packaging improvements |
68ada11e | 221 | for rpm based distros including CHAOS, RHEL, Fedora, and SLES. |
aaad2f72 BB |
222 | |
223 | spl-<version>.src.rpm | |
224 | - Fully rebuildable source rpm for utils. | |
225 | spl-modules-<version>.src.rpm | |
226 | - Fully rebuildable source rpm for kernel modules. | |
227 | ||
228 | spl-<version>.<arch>.rpm | |
229 | - Binary rpm for utils. The utils in this package are compatible | |
230 | with all spl-module rpms of the same version. | |
231 | ||
232 | spl-modules-<verion>-<kernel>.arch.rpm | |
233 | - Binary rpm containing the kernel modules for a specific kernel build. | |
234 | The package name contains the kernel version and you should have one | |
235 | of these packages installed to match every kernel on your system. | |
236 | spl-modules-devel-<verion>-<kernel>.arch.rpm | |
237 | - Binary rpm containing development header and module symbols needed | |
238 | for building additional kernel modules which are dependent on the | |
239 | spl module. | |
240 | ||
762b96f6 BB |
241 | * : Added SLES10 support. This includes all compatibility |
242 | changes to support 2.6.16 based kernels and the required | |
243 | build system improvements. | |
244 | ||
245 | * : Build System changes for SLES10: | |
246 | - Exclude -obj when detecting installed kernel source. | |
247 | - Detect -obj directory for out of tree kernel builds. | |
248 | - Allow kernel build system to set CC to ensure -m64 is set properly. | |
249 | This is an issue on 64-bit SLES systems which by default always | |
250 | build 32-bit binaries (unlike RHEL/Fedora which default to 64-bit) | |
251 | ||
252 | * : Configure Checks added for SLES10: | |
253 | - div64_64() renamed to div64_u64() as of 2.6.26. | |
254 | - global_page_state() fuction was introduced in 2.6.18 kernels. | |
255 | The earlier 2.6.16 based SLES10 must not try and use it, | |
256 | thankfully get_zone_counts() is still available. | |
257 | - monotonic_clock() is unavailable __gethrtime() must perform the | |
258 | HZ division as an 'unsigned long long' because the SPL only | |
259 | implements __udivdi3(), and not __divdi3() for 'long long' | |
260 | division on 32-bit arches. | |
261 | - mutex_lock_nested() was introduced as part of the mutex | |
262 | validator in 2.6.18, when it is unavailable it is safe to | |
263 | fallback to using a plain mutex_lock(). | |
264 | - SLES specific API change to vfs_unlink() and vfs_rename() which | |
265 | added a 'struct vfsmount *' argument. This was for something | |
266 | called the linux-security-module, but it appears that it was | |
267 | never adopted upstream. | |
268 | - spl_device_create() correctly mapped to class_device_create() | |
269 | for 2.6.13 to 2.6.17 based kernels, this is the preferred API. | |
270 | - Prior to 2.6.17 there were no *_pgdat helper functions in | |
271 | mm/mmzone.c. Instead for_each_zone() operated directly on | |
272 | pgdat_list which may or may not have been exported depending on | |
273 | how your kernel was compiled. A configure check was added to | |
274 | determine if you have the helpers or not, and if the needed | |
275 | symbols are exported. If they are not exported then they are | |
276 | dynamically aquired at runtime by kallsyms_lookup_name(). | |
277 | ||
278 | * : Packaging changes for SLES10 | |
279 | - Properly honor --prefix in build system and rpm spec file. | |
280 | - Add '--define require_kdir' to spec file to support building | |
281 | rpms against kernel sources installed in non-default locations. | |
282 | - Add '--define require_kobj' to spec file to support building | |
283 | rpms against kernel object installed in non-default locations. | |
284 | - Stop suppressing errors in autogen.sh script. | |
285 | - Improved logic to detect missing kernel objects when they are | |
286 | not located with the source. This is the common case for SLES | |
287 | as well as in-tree chaos kernel builds and is done to simply | |
288 | support for multiple arches. | |
289 | - Moved spl-devel build products to /usr/src/spl-<version>, a | |
290 | spl symlink is created to reference the last installed version. | |
291 | - Allow checking for exported symbols in both Module.symvers | |
292 | and Module.symvers. My stock SLES kernel ships an objects | |
293 | directory with Module.symvers, yet produces a Module.symvers | |
294 | in the local build directory. | |
295 | ||
296 | * : Added powerpc64 support. | |
297 | - Enable builds for powerpc64 ISA type. | |
298 | - Add DIV_ROUND_UP and roundup macros if unavailable. | |
299 | - Cast 64-bit values for %lld format string to (long long) to | |
300 | quiet compile warning. | |
301 | ||
302 | * module/splat/splat-ctl.c: Proper ioctl() 32/64-bit binary | |
303 | compatibility. We need to ensure the ioctl data itself is always | |
304 | packed the same for 32/64-bit binaries. Additionally, the correct | |
305 | thing to do is encode this size in bytes as part of the command | |
306 | using _IOC_SIZE(). | |
307 | ||
308 | * modules/spl/spl-kmem.c: Fixed a long standing bug in the debug | |
309 | tracing. The tcd_for_each() macro expected a NULL to terminate | |
310 | the trace_data[i] array but this was only ever true due to luck. | |
311 | All trace_data[] iterators are now properly capped by TCD_TYPE_MAX. | |
312 | ||
313 | * modules/spl/spl-kmem.c: To simplify debugging all symbols aquired | |
314 | dynamically using spl_kallsyms_lookup_name() are initially poisoned | |
315 | with SYMBOL_POISON. | |
316 | ||

318 | ||
319 | * : Tag spl-0.4.3 | |
320 | ||
321 | * configure.ac, *Makefile.am: Build system update. This includes | |
322 | resolving various build issues and adding support for the remaining | |
323 | common build targets. Available targets now include: | |
324 | ||
325 | - make all # Build everything | |
326 | - make install # Install everything | |
327 | - make clean # Clean up build products | |
328 | - make distclean # Clean up everything | |
329 | - make dist # Create package tarball | |
330 | - make srpm # Create package source RPM | |
331 | - make rpm # Create package binary RPMs | |
332 | - make tags # Create ctags and etags for everything | |
333 | ||
334 | Extra care was taken to ensure that the source RPMs are fully | |
335 | rebuildable against Fedora/RHEL/Chaos kernels. To build binary | |
336 | RPMs from the source RPM for your system simply run: | |
337 | ||
338 | rpmbuild --rebuild spl-x.y.z-1.src.rpm | |
339 | ||
340 | This will produce two binary RPMs with correct 'requires' | |
341 | dependencies for your kernel. One will contain all zpl modules | |
342 | and support utilities, the other is a devel package for compiling | |
343 | additional kernel modules which are dependent on the spl. | |
344 | ||
345 | spl-x.y.z-1_<kernel version>.x86_64.rpm | |
346 | spl-devel-x.y.2-1_<kernel version>.x86_64.rpm | |
347 | ||
348 | * : FC10 (linux-2.6.27.19) and i686 compatibility update. The | |
349 | list of support platforms has been extended to include FC10 | |
350 | systems and x86 architectures. It should be noted that kernels | |
351 | older the 2.6.27.19 should work but have not have not been tested. | |
352 | ||
353 | * configure.ac: Fix build issue preventing spl_config.h from being | |
354 | cleanly included by dependent packages. | |
355 | ||
356 | * module/spl/spl-taskq.c: Fix taskq_wait() not waiting bug. | |
357 | ||
358 | * module/spl/spl-xdr.c: Add XDR implementation provided by Ricardo | |
359 | Correia from Sun. | |
360 | ||
361 | * module/spl/spl-kmem.c: Linux VM integration cleanup. | |
362 | ||
363 | * module/spl/spl-kmem.c: Slab cache improvements and fixes. | |
364 | ||
365 | * modules/splat/*: Include additional SPLAT regression tests. | |
366 | ||
367 | * : Various bug fixes are more clearly detailed in the git | |
368 | commit logs. For a detailed summary of changes post version | |

377 | * module/spl/spl-kmem.c include/sys/kmem.h: Slab cache improvements: | |
378 | - Implement kmem cache alignment. | |
379 | - Implement slab ageing. | |
380 | - Optimized slab packing algorithm. | |
381 | - Fixed deadlock due to calling call kv_free() under the skc_lock. | |
382 | - Added additional SPLAT test cases | |
383 | - Performance optimizations | |
384 | ||
385 | * module/spl/spl-kmem.c include/sys/kmem.h: Linux VM integration. | |
386 | The Solaris global VM symbols minfree, desfree, lotsfree, needfree, | |
387 | swapfs_minfree, swapfs_reserve, availrmem, freemem, and physmem are | |
388 | now available and loosely integrating with the Linux VM. Some | |
389 | tuning will undoubtably be needed and these tunables are available | |
390 | in /proc/sys/kernel/spl/vm/* for this very reason. | |
391 | ||
392 | * config/spl-build.m4: New configure checks needed when building | |
393 | against 2.6.27+ kernels. More work is needed here. | |

419 | * : Add autogen.sh products. | |
420 | ||
f8b2932a | 421 | * configure.ac : Use AC_CONFIG_AUX_DIR to put autograph products |
bf9f3bac | 422 | in ./auotconf. |
423 | ||
424 | * autogen.sh : Use --copy to avoid symlinks, remove error | |
425 | redirection, run aclocal before libtoolize. | |

428 | ||
429 | * include/sys/sunddi.h, modules/spl/spl-module.c : Removed default | |
430 | udev support from sunddi implementation because it uses GPL-only | |
431 | symbols. This support is optionally available for SPL consumers | |
432 | if they define HAVE_GPL_ONLY_SYMBOLS and license their module as | |
433 | GPL using the MODULE_LICENSE("GPL") macro. | |

458 | * : Tag spl-0.3.3 | |
459 | ||
460 | * : modules/sys/kmem-slab.c : Refined SPL slab to include | |
461 | per-cpu caches, removed internal hash, other general | |
462 | performance improvements. Much work remain but it's pretty | |
463 | good for an initial implementation. | |
464 | ||

466 | ||
467 | * : modules/sys/kmem-slab.c : Re-implemented the slab to no | |
468 | longer be based on the linux slab but to be it's own complete | |
469 | implementation. The new slab behaves much more like the | |
470 | Solaris slab than the Linux slab. | |

474 | * : Tag spl-0.3.2 | |
475 | ||
476 | * : Extensive improvements to the build system to detect kernel | |
477 | API changes so we can flexibly build with a wider range of kernel | |
478 | versions. The code has now been testing with the 2.6.18-32chaos | |
479 | and 2.6.25.3-18.fc9 kernels, however we should also be compatible | |
480 | with other kernels in the range of 2.6.18-2.6.25. | |

484 | * configure.ac, autoconf/* : Initial pass at resolving | |
485 | API changes introduced by kernels newer than 2.6.18. | |

500 | ||
501 | * include/sys/mutex.h : Implemented a close approximation | |
502 | of adaptive mutexes. These changes however required me to | |
503 | export a new symbol from the kernel proper 'task_curr()' | |
504 | which means we are now dependant on a patched kernel. | |

509 | ||
510 | * modules/spl/spl-proc.c : Add /proc/sys/spl/version. | |

513 | ||
514 | * include/sys/kmem.h : Make sure that when calling __vmem_alloc | |
515 | that we do not have __GFP_ZERO set. Once the memory is allocated | |
516 | then zero out the memory if __GFP_ZERO is passed to | |
517 | __vmem_alloc. | |
518 | ||

520 | ||
521 | * modules/spl/spl-kmem.c : Make sure to disable interrupts | |
522 | when necessary to avoid deadlocks. We were seeing the deadlock | |
523 | when calling kmem_cache_generic_constructor() and then an interrupt | |
524 | forced us to end up calling kmem_cache_generic_destructor() | |
525 | which caused our deadlock. | |

529 | : Initial commit of the solaris porting layer (spl). Included | |
530 | in addition to the source is an initial autoconf / configure | |
531 | style build system. |
