3 | * : Tag spl-0.4.5 | |
4 | ||
5 | * FC11 and SLES11 support: This includes all compatibility changes | |
6 | to support 2.6.29 based kernels and the required build system | |
7 | improvements. | |
8 | * module/spl/spl-module.c: Register a basic compat ioctl handler | |
9 | for 32-bit user vs 64-bit kernel compatibility. This is the default | |
10 | build environment for all 64-bit SLES systems. | |
11 | * config/spl-build.m4: Check arch/default path when detecting kernel | |
12 | objects under SLES. We still preferentially use arch/arch if | |
13 | available but if that fails it is acceptable to use default. | |
14 | * module/spl/spl-vnode.: Use HAVE_PATH_IN_NAMEIDATA compat macros | |
15 | for maximum kernel compatibility. | |
16 | * config/spl-build.m4: Remove LINUXINCLUDE from autoconf wrapper. | |
17 | This breaks the 2.6.28+ kernels build system, all kernel build systems | |
18 | at least post 2.6.16 will set this properly so we should not. | |
19 | * include/sys/vmsystm.h, module/spl/spl-kmem.c: Perferentially use the | |
20 | global_page_state() API when your kernel supports the required enums. | |
21 | * include/sys/debug.h: Add ASSERTV macro to simplify removing | |
22 | variables (the V in ASSERTV) which are only used in ASSERT(). | |
23 | * include/sys/debug.h: Disable stack overflow checking by default | |
24 | when build with --enable-debug, modern kernels now provide this. | |
25 | * patches/fc11-spl-export-symbols.patch: Recommended missing symbols | |
26 | patch for FC11. This is not required for correct functionality but | |
27 | it is recommended for individuals who are already patching the kernel. | |
28 | ||
29 | * Additional Solaris API emulation: | |
30 | * include/sys/taskq.h: Add basic taskq support for the flag | |
31 | TASKQ_THREADS_CPU_PCT which is used to scale the number of threads | |
32 | based on the number of online CPUs. | |
33 | * include/sys/file.hi, module/spl/spl-generic.c: Add support for | |
34 | fake ioctls which originate from the kernel instead of user space. | |
35 | * include/sys/acl.h: Add ACE_ALL_PERMS ACL definition. | |
36 | * include/sys/cred.h, module/splat/splat-cred.c: Add basic credential | |
37 | support and splat regression tests. | |
38 | ||
39 | * Bug fixes: | |
40 | * include/sys/isa_defs.h: Add more endianess paranoia. | |
41 | * module/spl/spl-time.c: Integer overflow after ~164 days. | |
42 | * include/sys/debug.h: NULL dereference by tcd_for_each(). | |
43 | * module/splat/splat-kmem.c: Allow kmem or vmem based slabs for | |
44 | slab_lock and slab_overcommit tests. This may still be an issue on | |
45 | 32-bit systems due to the small virtual address space. | |
46 | * module/spl/spl-module.c: Positive Solaris ioctl return codes are | |
47 | need to be negated for use by libc to ensure errno is set correctly. | |

51 | * : Tag spl-0.4.4 | |
52 | ||
aaad2f72 | 53 | * : Generic distro friendly build system / packaging improvements |
68ada11e | 54 | for rpm based distros including CHAOS, RHEL, Fedora, and SLES. |
aaad2f72 BB |
55 | |
56 | spl-<version>.src.rpm | |
57 | - Fully rebuildable source rpm for utils. | |
58 | spl-modules-<version>.src.rpm | |
59 | - Fully rebuildable source rpm for kernel modules. | |
60 | ||
61 | spl-<version>.<arch>.rpm | |
62 | - Binary rpm for utils. The utils in this package are compatible | |
63 | with all spl-module rpms of the same version. | |
64 | ||
65 | spl-modules-<verion>-<kernel>.arch.rpm | |
66 | - Binary rpm containing the kernel modules for a specific kernel build. | |
67 | The package name contains the kernel version and you should have one | |
68 | of these packages installed to match every kernel on your system. | |
69 | spl-modules-devel-<verion>-<kernel>.arch.rpm | |
70 | - Binary rpm containing development header and module symbols needed | |
71 | for building additional kernel modules which are dependent on the | |
72 | spl module. | |
73 | ||
762b96f6 BB |
74 | * : Added SLES10 support. This includes all compatibility |
75 | changes to support 2.6.16 based kernels and the required | |
76 | build system improvements. | |
77 | ||
78 | * : Build System changes for SLES10: | |
79 | - Exclude -obj when detecting installed kernel source. | |
80 | - Detect -obj directory for out of tree kernel builds. | |
81 | - Allow kernel build system to set CC to ensure -m64 is set properly. | |
82 | This is an issue on 64-bit SLES systems which by default always | |
83 | build 32-bit binaries (unlike RHEL/Fedora which default to 64-bit) | |
84 | ||
85 | * : Configure Checks added for SLES10: | |
86 | - div64_64() renamed to div64_u64() as of 2.6.26. | |
87 | - global_page_state() fuction was introduced in 2.6.18 kernels. | |
88 | The earlier 2.6.16 based SLES10 must not try and use it, | |
89 | thankfully get_zone_counts() is still available. | |
90 | - monotonic_clock() is unavailable __gethrtime() must perform the | |
91 | HZ division as an 'unsigned long long' because the SPL only | |
92 | implements __udivdi3(), and not __divdi3() for 'long long' | |
93 | division on 32-bit arches. | |
94 | - mutex_lock_nested() was introduced as part of the mutex | |
95 | validator in 2.6.18, when it is unavailable it is safe to | |
96 | fallback to using a plain mutex_lock(). | |
97 | - SLES specific API change to vfs_unlink() and vfs_rename() which | |
98 | added a 'struct vfsmount *' argument. This was for something | |
99 | called the linux-security-module, but it appears that it was | |
100 | never adopted upstream. | |
101 | - spl_device_create() correctly mapped to class_device_create() | |
102 | for 2.6.13 to 2.6.17 based kernels, this is the preferred API. | |
103 | - Prior to 2.6.17 there were no *_pgdat helper functions in | |
104 | mm/mmzone.c. Instead for_each_zone() operated directly on | |
105 | pgdat_list which may or may not have been exported depending on | |
106 | how your kernel was compiled. A configure check was added to | |
107 | determine if you have the helpers or not, and if the needed | |
108 | symbols are exported. If they are not exported then they are | |
109 | dynamically aquired at runtime by kallsyms_lookup_name(). | |
110 | ||
111 | * : Packaging changes for SLES10 | |
112 | - Properly honor --prefix in build system and rpm spec file. | |
113 | - Add '--define require_kdir' to spec file to support building | |
114 | rpms against kernel sources installed in non-default locations. | |
115 | - Add '--define require_kobj' to spec file to support building | |
116 | rpms against kernel object installed in non-default locations. | |
117 | - Stop suppressing errors in autogen.sh script. | |
118 | - Improved logic to detect missing kernel objects when they are | |
119 | not located with the source. This is the common case for SLES | |
120 | as well as in-tree chaos kernel builds and is done to simply | |
121 | support for multiple arches. | |
122 | - Moved spl-devel build products to /usr/src/spl-<version>, a | |
123 | spl symlink is created to reference the last installed version. | |
124 | - Allow checking for exported symbols in both Module.symvers | |
125 | and Module.symvers. My stock SLES kernel ships an objects | |
126 | directory with Module.symvers, yet produces a Module.symvers | |
127 | in the local build directory. | |
128 | ||
129 | * : Added powerpc64 support. | |
130 | - Enable builds for powerpc64 ISA type. | |
131 | - Add DIV_ROUND_UP and roundup macros if unavailable. | |
132 | - Cast 64-bit values for %lld format string to (long long) to | |
133 | quiet compile warning. | |
134 | ||
135 | * module/splat/splat-ctl.c: Proper ioctl() 32/64-bit binary | |
136 | compatibility. We need to ensure the ioctl data itself is always | |
137 | packed the same for 32/64-bit binaries. Additionally, the correct | |
138 | thing to do is encode this size in bytes as part of the command | |
139 | using _IOC_SIZE(). | |
140 | ||
141 | * modules/spl/spl-kmem.c: Fixed a long standing bug in the debug | |
142 | tracing. The tcd_for_each() macro expected a NULL to terminate | |
143 | the trace_data[i] array but this was only ever true due to luck. | |
144 | All trace_data[] iterators are now properly capped by TCD_TYPE_MAX. | |
145 | ||
146 | * modules/spl/spl-kmem.c: To simplify debugging all symbols aquired | |
147 | dynamically using spl_kallsyms_lookup_name() are initially poisoned | |
148 | with SYMBOL_POISON. | |

151 | ||
152 | * : Tag spl-0.4.3 | |
153 | ||
154 | * configure.ac, *Makefile.am: Build system update. This includes | |
155 | resolving various build issues and adding support for the remaining | |
156 | common build targets. Available targets now include: | |
157 | ||
158 | - make all # Build everything | |
159 | - make install # Install everything | |
160 | - make clean # Clean up build products | |
161 | - make distclean # Clean up everything | |
162 | - make dist # Create package tarball | |
163 | - make srpm # Create package source RPM | |
164 | - make rpm # Create package binary RPMs | |
165 | - make tags # Create ctags and etags for everything | |
166 | ||
167 | Extra care was taken to ensure that the source RPMs are fully | |
168 | rebuildable against Fedora/RHEL/Chaos kernels. To build binary | |
169 | RPMs from the source RPM for your system simply run: | |
170 | ||
171 | rpmbuild --rebuild spl-x.y.z-1.src.rpm | |
172 | ||
173 | This will produce two binary RPMs with correct 'requires' | |
174 | dependencies for your kernel. One will contain all zpl modules | |
175 | and support utilities, the other is a devel package for compiling | |
176 | additional kernel modules which are dependent on the spl. | |
177 | ||
178 | spl-x.y.z-1_<kernel version>.x86_64.rpm | |
179 | spl-devel-x.y.2-1_<kernel version>.x86_64.rpm | |
180 | ||
181 | * : FC10 (linux-2.6.27.19) and i686 compatibility update. The | |
182 | list of support platforms has been extended to include FC10 | |
183 | systems and x86 architectures. It should be noted that kernels | |
184 | older the 2.6.27.19 should work but have not have not been tested. | |
185 | ||
186 | * configure.ac: Fix build issue preventing spl_config.h from being | |
187 | cleanly included by dependent packages. | |
188 | ||
189 | * module/spl/spl-taskq.c: Fix taskq_wait() not waiting bug. | |
190 | ||
191 | * module/spl/spl-xdr.c: Add XDR implementation provided by Ricardo | |
192 | Correia from Sun. | |
193 | ||
194 | * module/spl/spl-kmem.c: Linux VM integration cleanup. | |
195 | ||
196 | * module/spl/spl-kmem.c: Slab cache improvements and fixes. | |
197 | ||
198 | * modules/splat/*: Include additional SPLAT regression tests. | |
199 | ||
200 | * : Various bug fixes are more clearly detailed in the git | |
201 | commit logs. For a detailed summary of changes post version | |
202 | 0.4.2 check the git commit logs. | |

208 | * : Tag spl-0.4.2 | |
209 | ||
210 | * module/spl/spl-kmem.c include/sys/kmem.h: Slab cache improvements: | |
211 | - Implement kmem cache alignment. | |
212 | - Implement slab ageing. | |
213 | - Optimized slab packing algorithm. | |
214 | - Fixed deadlock due to calling call kv_free() under the skc_lock. | |
215 | - Added additional SPLAT test cases | |
216 | - Performance optimizations | |
217 | ||
218 | * module/spl/spl-kmem.c include/sys/kmem.h: Linux VM integration. | |
219 | The Solaris global VM symbols minfree, desfree, lotsfree, needfree, | |
220 | swapfs_minfree, swapfs_reserve, availrmem, freemem, and physmem are | |
221 | now available and loosely integrating with the Linux VM. Some | |
222 | tuning will undoubtably be needed and these tunables are available | |
223 | in /proc/sys/kernel/spl/vm/* for this very reason. | |
224 | ||
225 | * config/spl-build.m4: New configure checks needed when building | |
226 | against 2.6.27+ kernels. More work is needed here. | |
227 | ||
228 | * : Minor cleanup see the 'git log' for full details. | |

251 | ||
252 | * : Add autogen.sh products. | |
253 | ||
f8b2932a | 254 | * configure.ac : Use AC_CONFIG_AUX_DIR to put autograph products |
bf9f3bac | 255 | in ./auotconf. |

261 | ||
262 | * include/sys/sunddi.h, modules/spl/spl-module.c : Removed default | |
263 | udev support from sunddi implementation because it uses GPL-only | |
264 | symbols. This support is optionally available for SPL consumers | |
265 | if they define HAVE_GPL_ONLY_SYMBOLS and license their module as | |
266 | GPL using the MODULE_LICENSE("GPL") macro. | |

291 | * : Tag spl-0.3.3 | |
292 | ||
293 | * : modules/sys/kmem-slab.c : Refined SPL slab to include | |
294 | per-cpu caches, removed internal hash, other general | |
295 | performance improvements. Much work remain but it's pretty | |
296 | good for an initial implementation. | |

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

309 | * : Extensive improvements to the build system to detect kernel | |
310 | API changes so we can flexibly build with a wider range of kernel | |
311 | versions. The code has now been testing with the 2.6.18-32chaos | |
312 | and 2.6.25.3-18.fc9 kernels, however we should also be compatible | |
313 | with other kernels in the range of 2.6.18-2.6.25. | |

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

355 | when necessary to avoid deadlocks. We were seeing the deadlock | |
356 | when calling kmem_cache_generic_constructor() and then an interrupt | |
357 | forced us to end up calling kmem_cache_generic_destructor() | |
358 | which caused our deadlock. | |
