------------------------------------------------------------------- Mon Mar 30 11:59:20 CEST 2020 - nstange@suse.de - scripts: enable s390x for SLE15-SP2 - commit 933574a ------------------------------------------------------------------- Wed Mar 25 10:45:50 CET 2020 - nstange@suse.de - scripts: Generate ExclusiveArch in spec file dynamically s390x support is slowly being introduced for newly created master-livepatch based branches. In order to avoid problems with existing branches for e.g. the maintenance team, don't add s390x to the hard-coded list of ExclusiveArchs, but let tar-up.sh enable it dynamically depending on the codestream in question. For now, s390x builds will be enabled on SLE12-SP5, beginning with SLE12-SP5_Update_3 onwards. - commit 27b683d ------------------------------------------------------------------- Mon Dec 2 13:49:24 CET 2019 - mbenes@suse.cz - Revert "shadow variables: allow for dynamic initialization" This reverts commit 843c6fa42429afc1682cdb39119e7a011af2abc9. - commit 23d37c8 ------------------------------------------------------------------- Mon Dec 2 13:40:37 CET 2019 - mbenes@suse.cz - Revert "shadow variables: introduce upstream patch" This reverts commit e899c4fd3fe7602ebd70f578d8475f1049de7c78. - commit c1be24c ------------------------------------------------------------------- Mon Dec 2 13:38:18 CET 2019 - mbenes@suse.cz - Revert "shadow variables: drop EXPORT_SYMBOL()s" This reverts commit ac6cfebd7f831213ebcd4b2690672871572ec49e. - commit 5771a4b ------------------------------------------------------------------- Mon Dec 2 13:38:04 CET 2019 - mbenes@suse.cz - Revert "shadow variables: share shadow data among KGraft modules" This reverts commit 8e1e705d4d56981949f7ae3854d8e1cc2be7f40f. - commit 1c87412 ------------------------------------------------------------------- Mon Dec 2 13:37:30 CET 2019 - mbenes@suse.cz - Revert "shadow variables: add KGR_SHADOW_ID helper" This reverts commit 237c8f3d13c382321d3e65d138d328eae0b82f6c. - commit 41936fd ------------------------------------------------------------------- Sat Sep 7 18:53:16 CEST 2019 - nstange@suse.de - uname_patch: convert to the syscall stub wrapper macros from klp_syscalls.h In order to make the live patch to the newuname() syscall work on kernels >= 4.17 again, convert it to the KLP_SYSCALL_*() wrapper macros provided by klp_syscalls.h. References: bsc#1149841 - commit b5af38e ------------------------------------------------------------------- Sat Sep 7 18:53:15 CEST 2019 - nstange@suse.de - Provide wrapper macros for syscall naming Live patching syscall stubs is a common task, for example any live patch package modifies the newuname syscall. For the actual definitions of the live patched syscall stubs, the __SYSCALL_DEFINEx() name can always be (and often has been) used like e.g. __SYSCALL_DEFINEx(3, _klp_timer_create, const clockid_t, which_clock, struct sigevent __user *, timer_event_spec, timer_t __user *, created_timer_id) { /* New implementation */ } Up to kernel 4.16, this used to define a function named "SyS_klp_timer_create" which could then be used to live patch the "SyS_timer_create". However, beginning with kernel version 4.17, resp. upstream commits - fa697140f9a2 ("syscalls/x86: Use 'struct pt_regs' based syscall calling convention for 64-bit syscalls") - e145242ea0df ("syscalls/core, syscalls/x86: Clean up syscall stub naming convention") - d5a00528b58c ("syscalls/core, syscalls/x86: Rename struct pt_regs-based sys_*() to __x64_sys_*()"), things became more complex: - The naming of the resulting stubs now varies across architecture. - Some architectures (x86_64, s390x) instantiate an additional compat stub for syscalls sharing a common implementation between 32 and 64 bits. (The 32 bit entry code used to convert from the 32 bit ABI to 64 bit and simply call the 64 bit syscall stub afterwards. That's handled by the new 32 bit stubs now.) - The stubs' signatures have changed: each argument used to get mapped to either long or long long, but on x86_64, the stubs are now receiving a single struct pt_regs only -- it's their responsibility to extract the arguments as appropriate. In order to not require each and every live patch touching syscalls to include an insane amount of ifdeffery, provide a set of #defines hiding it: 1.) KLP_SYSCALL_SYM(name) expands to the syscall stub name for 64 bits as defined by _SYSCALL_DEFINEx(x, _name, ...). 2.) If the architeture requires 32bit specific stubs for syscalls sharing a common implementation between 32 and 64bits, the KLP_ARCH_HAS_SYSCALL_COMPAT_STUBS macro is defined. 3.) If KLP_ARCH_HAS_SYSCALL_COMPAT_STUBS is defined, then KLP_SYSCALL_COMPAT_STUB_SYM(name) expands to the syscall stub name for 32 bits as defined by _SYSCALL_DEFINEx(x, _name, ...). 4.) For syscalls not sharing a common implementation between 32 and 64 bits, i.e. those defined by COMPAT_SYSCALL_DEFINEx(), the macro KLP_COMPAT_SYSCALL_SYM(name) expands to the stub name defined as defined by COMPAT_SYSCALL_DEFINEx(x, _name, ...). 5.) Finally, for hiding differences between the signatures, provide the macro KLP_SYSCALL_DECLx(x, sym, ...) which expands to a declaration of sym, with the x arguments either mapped to long resp. long long each, or collapsed to a single struct pt_regs argument as appropriate for the architecture. Note that these macros are defined as appropriate on kernels before and after 4.17, so that live patch code can be shared.

This results in compilation errors like the following: uname_patch/livepatch_uname.c:36:10: fatal error: klp_convert.h: No such file or directory #include "klp_convert.h" ^~~~~~~~~~~~~~~ Fix this by appending '-I$(obj)' to ccflags-y within the Makefile created by scripts/create-makefile.sh. Note that "$(obj)" is set to the current source directory before the Makefile is sourced by Kbuild. - commit b30a48e ------------------------------------------------------------------- Fri Aug 23 13:18:43 CEST 2019 - nstange@suse.de - New branch for SLE15-SP2_Update_0 - commit ae6163f ------------------------------------------------------------------- Thu Mar 7 15:23:42 CET 2019 - mbenes@suse.cz - livepatch_main.c: Adaptation to a new livepatch API The atomic replace patch set among others removed the two-stage API. There is no (un)registration step needed now. SLES backport defines KLP_NOREG_API macro to easily distinguish whether the kernel provides the old or the new API. Use it and change the module init and exit functions accordingly. - commit 060163b ------------------------------------------------------------------- Thu Feb 7 14:13:00 CET 2019 - mbenes@suse.cz - uname_patch: Use klp-convert macros and rely on klp-convert where possible - commit 4c9eb70 ------------------------------------------------------------------- Wed Feb 6 14:12:44 CET 2019 - mbenes@suse.cz - Define macros to switch easily between klp-convert and kallsyms Kallsyms trick does not have to be used for resolving undefined symbols when klp-convert is available. It would be great though to share live patches sources between both modes of operation. Define macros to help with the task. Their definitions depend on whether USE_KLP_CONVERT macro is defined. tar-up.sh script is responsible to decide. - commit e3a42b7 ------------------------------------------------------------------- Wed Feb 6 10:53:44 CET 2019 - mbenes@suse.cz - Use klp-convert where provided klp-convert tool converts undefined symbols in a live patch kernel module to special relocation records which are resolved by the kernel. It allows to omit kallsyms tricks. Wire it to the spec file and let tar-up.sh script decide if it is to be used depending on a codestream. SLE15-SP1 is supported currently. - commit 3efd330 ------------------------------------------------------------------- Tue Dec 11 11:27:23 CET 2018 - mbenes@suse.cz - uname_patch: don't hold uts_sem while accessing userspace memory Backport upstream patch 42a0cc347858 ("sys: don't hold uts_sem while accessing userspace memory"). - commit d4e00de ------------------------------------------------------------------- Tue Oct 2 16:38:19 CEST 2018 - mbenes@suse.cz - scripts/tar-up.sh: Add ppc64le to ExclusiveArch even for SLE12-SP2 - commit 77a8a8b ------------------------------------------------------------------- Wed Aug 8 15:08:00 CEST 2018 - nstange@suse.de - Provide common kallsyms wrapper API With bsc#1103203, the need for disambiguating between a multiply defined symbol arose. This is something the kallsyms_lookup_name() based code snippet we used to copy&paste to every individual CVE fix can't handle. Implement a proper wrapper API for doing the kallsyms lookups. - commit bd113d8 ------------------------------------------------------------------- Wed Aug 8 15:07:59 CEST 2018 - nstange@suse.de - Provide common kallsyms wrapper API With bsc#1103203, the need for disambiguating between a multiply defined symbol arose. This is something the kallsyms_lookup_name() based code snippet we used to copy&paste to every individual CVE fix can't handle. Implement a proper wrapper API for doing the kallsyms lookups. - commit 4aed7d2 ------------------------------------------------------------------- Wed Jul 11 13:55:14 CEST 2018 - nstange@suse.de - provide KGR_SHADOW_ID() helper macro - provide KLP_SHADOW_ID() helper macro In analogy to the KGR_SHADOW_ID() macro, introduce KLP_SHADOW_ID() for the construction of unique shadow variable id's. - commit 7325c49 ------------------------------------------------------------------- Sun Jul 8 13:02:18 CEST 2018 - nstange@suse.de - scripts/register-patches.sh: implement conditional inclusion Currently, subpatches provide a patched_funcs.csv file describing what needs to be patched. register-patches.sh inspects those to assemble one global klp_patch structure. The current format for these patched_funcs.csv's is obj old_func(,sympos) newfun However, sometimes subpatches depend on some kernel configuration values like CONFIG_X86_64 and functions shall get patched only if the target kernel configuration matches. Extends the patched_funcs.csv format to obj old_func(,sympos) newfun (cpp condition) where everything coming after 'newfun' is taken to be a CPP condition to be used for conditional inclusion. In case there's no condition specified, assign that entry the same semantics as if a '1' had been given. Make register-patches.sh guard the corresponding klp_func entries with #if pragmas. Furthermore, let it guard the enclosing klp_object instances by or'ing together all its klp_funcs' conditions. For the sake of better readability, omit redundant #if pragmas as well as condition clauses. In particular, - if a function entry hasn't got any condition explicitly specified, there won't be any #if pragma, neither at the klp_func nor at the klp_object level, - if multiple function entries for an object are protected by the same condition, it'll be or'ed in at the klp_object level only once, - if all of an object's functions share the same condition, no #if pragmas will be emitted at the klp_func level because they would only duplicate what's already there for the enclosing object and - multiple subsequent function entries sharing the same condition get collated. - commit 56f0729 ------------------------------------------------------------------- Sun Jul 8 13:02:17 CEST 2018 - nstange@suse.de - scripts/register-patches.sh: allow spaces as patched_funcs.csv separators Currently there's one single cut(1) usage which requires that (single) tabs are used as field separators for the patched_funcs.csv. As the rest of the code can deal with sequences of any whitespace already, this imposes an unnecessary restriction on the format. Substitute that cut(1) usage by a sed(1) invocation as appropriate. - commit 9852661 ------------------------------------------------------------------- Mon Jun 4 15:20:08 CEST 2018 - mbenes@suse.cz - livepatch_main.c: Set .replace to true - commit 643f04c ------------------------------------------------------------------- Mon May 14 08:30:00 CEST 2018 - nstange@suse.de - scrips/create-makefile.sh: add support for assembly files - commit cf2464a ------------------------------------------------------------------- Mon Mar 5 15:44:31 CET 2018 - nstange@suse.de - shadow variables: allow for dynamic initialization Currently, the only shadow variable initialization scheme exposed by the allocation API is to let klp_shadow_alloc() resp. klp_shadow_get_or_alloc() memcpy some user provided buffer to the freshly allocated shadow variable. This is too limited for shadow structures containing pointers into themselves like list_heads or mutexes. Change the internal __klp_shadow_get_or_alloc() to take a pointer to an initializer functions and call that in place of the memcpy() operation. In order to retain former functionality of klp_shadow_alloc() and klp_shadow_get_or_alloc(), make them pass the new __klp_shadow_memcpy_init() wrapper to __klp_shadow_get_or_alloc(). Finally, introduce the new klp_shadow_alloc_with_init() and klp_shadow_get_or_alloc_with_init() which pass a user provided initializer function pointer onwards to __klp_shadow_get_or_alloc(). - commit 843c6fa ------------------------------------------------------------------- Wed Dec 6 14:40:14 CET 2017 - mbenes@suse.cz - Revert "shadow variables: introduce upstream patch" This reverts commit e899c4fd3fe7602ebd70f578d8475f1049de7c78. - commit a27c66a ------------------------------------------------------------------- Wed Dec 6 14:37:09 CET 2017 - mbenes@suse.cz - Revert "shadow variables: drop EXPORT_SYMBOL()s" This reverts commit ac6cfebd7f831213ebcd4b2690672871572ec49e. - commit 40d0ba6 ------------------------------------------------------------------- Wed Dec 6 14:37:06 CET 2017 - mbenes@suse.cz - Revert "shadow variables: share shadow data among KGraft modules" This reverts commit 8e1e705d4d56981949f7ae3854d8e1cc2be7f40f. - commit d184b38 ------------------------------------------------------------------- Wed Dec 6 14:36:56 CET 2017 - mbenes@suse.cz - Revert "shadow variables: add KGR_SHADOW_ID helper" This reverts commit 237c8f3d13c382321d3e65d138d328eae0b82f6c. - commit 22d6153 ------------------------------------------------------------------- Wed Dec 6 12:18:06 CET 2017 - mbenes@suse.cz - rpm/config.sh: Use SUSE:SLE-15:GA project - commit ff32fc9 ------------------------------------------------------------------- Wed Dec 6 12:14:17 CET 2017 - mbenes@suse.cz - Revert "scripts: Generate ExclusiveArch in spec file dynamically" This reverts commit 95ed856ea8f99b4e48d7d324278b3628d2ac2fa2.

All currently supported kernels (that is, everything since SLE12_Update_14 and SLE12-SP1_Update_5) have sympos support. We can drop compat, because we don't need it anymore. - commit 11e3220 ------------------------------------------------------------------- Thu Nov 30 15:15:20 CET 2017 - mbenes@suse.cz - scripts: Generate ExclusiveArch in spec file dynamically ppc64le architecture kernel support is not present in all currently supported branches. It may cause problem for the maintenance team. Generate ExclusiveArch dynamically. It should be 'ppc64le x86_64' for SLE12-SP3 and 'x86_64' for the rest. - commit 95ed856 ------------------------------------------------------------------- Thu Nov 16 14:27:46 CET 2017 - mbenes@suse.cz - rpm/kgraft-patch.spec: Add ppc64le as a supported arch ppc64le is about to be supported in Live Patching product. Add it to ExclusiveArch tag. - commit 8437c94 ------------------------------------------------------------------- Thu Nov 16 14:26:35 CET 2017 - mbenes@suse.cz - rpm/kgraft-patch.spec: Remove s390x from supported archs s390x is not supported in Live Patching product. Remove it from ExclusiveArch. - commit f9614f2 ------------------------------------------------------------------- Tue Oct 31 10:34:53 CET 2017 - nstange@suse.de - livepatch_main.c: klp_patch_init(): fix error handling In case either of the invocations of klp_register_patch() or klp_enable_patch() fails, anything which has been setup by the prior per-(sub-)patch initialiation code, i.e. the expansion of @@KLP_PATCHES_INIT_CALLS@@, won't get undone. Fix this. Also make klp_patch_init() look more like the common 'goto err' idiom and adjust scripts/register_patches.sh accordingly. Fix for commit 7e20201cdcb8 ("kGraft to livepatch migration. API change."). - commit 6552b44 ------------------------------------------------------------------- Tue Oct 31 10:34:52 CET 2017 - nstange@suse.de - scripts/register_patches.sh: generate klp_object array The KLP API doesn't take a flat list of to be patched functions like KGraft did, but introduces an intermediate layer: struct klp_object. Each klp_patch instance is supposed to reference an array of klp_object's which in turn provide an array of klp_func's each. To facilitate merging, we want to generate this list of klp_object's automatically, exactly like we did for the flat function list with KGraft. For each klp_patch instance, there must be at most one klp_object entry referring to the same object. Hence care must be taken not to add an entry for the same object twice in case two different (sub-)patches both patch some functions therein. Require from each (sub-)patch to provide the list of to be patched symbols in a file named SUBPATCH/patched_funcs.csv with each line conforming to the obj old_func(,sympos) new_func pattern. Make scripts/register.sh generate an klp_object array initializer based on this and let it expand the @@KLP_PATCHES_OBJS@@ tag within livepatch_main.c accordingly. Do not replace the now obsolete @@KLP_PATCHES_FUNCS@@ anymore. Add and remove the @@KLP_PATCHES_OBJS@@ and @@KLP_PATCHES_FUNCS@@ markers to and from livepatch_main.c respectively.

External rename. External rename and thus final step of kGraft -> upstream livepatch migration. kgraft-patch* modules are now livepatch* and live in /lib/modules/$(uname -r)/livepatch. References: fate#323682 [ mb: changelog ] - commit f842fd5 ------------------------------------------------------------------- Thu Oct 5 12:12:29 CEST 2017 - nstange@suse.de - shadow variables: add KGR_SHADOW_ID helper As shadow variables are supposed to be shared among different KGraft modules their id's must be compile time constants. Introduce the KGR_SHADOW_ID helper macro for generating them in a uniform manner based on the bsc# number and a local id. - commit 237c8f3 ------------------------------------------------------------------- Thu Oct 5 12:12:28 CEST 2017 - nstange@suse.de - shadow variables: share shadow data among KGraft modules As it stands, each KGraft module maintains its own set of shadow variable management structures and thus, shadow variables are not sharable between livepatch modules. This behaviour is different from the upstream implementation and, as pointed out by Miroslav Benes, it also opens up an opportunity for a small window where the system might become vulnerable again during transition as we stack new livepatches on top. Let all KGraft patches share the shadow data. Sharing is implemented by moving the management structures from a KGraft module's .data to dynamically allocated memory. Each KGraft module will have specifically named pointers, 'kgr_shadow_hash12' and 'kgr_shadow_lock12', referencing them. Upon initialization, a KGraft module will discover already existing such shadow data by kallsyms-searching all loaded modules for these pointer symbols. If none is found, a new instance is allocated. The newly introduced kgr_shadow_init() implementing this is idempotent and can thus be called from the bsc# subpatches' initializers if needed. Upon KGraft module removal, the new kgr_shadow_cleanup() will conduct another kallsyms search and deallocate the shadow data in case there are no more users. kgr_shadow_cleanup() is also idempotent. Initialization and teardown of the common shadow data is serialized with the module_mutex which has to be taken for the kallsyms search anyway. - commit 8e1e705 ------------------------------------------------------------------- Thu Oct 5 12:12:27 CEST 2017 - nstange@suse.de - shadow variables: drop EXPORT_SYMBOL()s The shadow variable API will only ever get used by the KGraft module itself and thus, there's no need for exporting it. Drop all EXPORT_SYMBOL annotations. - commit ac6cfeb ------------------------------------------------------------------- Thu Oct 5 12:12:26 CEST 2017 - nstange@suse.de - shadow variables: introduce upstream patch Joe Lawrence posted the sixth version of his shadow variable patch [1] implementing the association of additional out-of-band data members to existing structure instances from livepatches. Jiri Kosina has applied this to his git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching.git for-4.15/shadow-variables tree and thus, it's queued up and close to getting merged. The plan is to eventually backport this shadow variable support to SLE kernels, but we also want to have it usable from KGraft modules by now. Port the implementation to the kraft-patches module. Namely, - dump shadow.c in it's current upstream state as it is after commits 439e7271dc2b ("livepatch: introduce shadow variable API") 5d9da759f758 ("livepatch: __klp_shadow_get_or_alloc() is local to shadow.c") 19205da6a0da ("livepatch: Small shadow variable documentation fixes") - add a shadow.h header and declare the newly introduced functions there - and incorporate the new files into the KGraft module's build system.

It discovers those and tweaks the main entry point, kgr_patch_main.c, as needed. However, a remaining manual merging task is to list a (sub)patch's source archive in rpm/kgraft-patch.spec and to %setup it. Make scripts/register-patches.sh do this. Namely, - introduce the @@KGR_PATCHES_SOURCES@@ and @@KGR_PATCHES_SETUP_SOURCES@@ placeholders in rpm/kgraft-patch.spec - and make scripts/register-patches.sh expand those within a spec file to be given as an additional command line argument. Finally, adjust scripts/tar-up.sh accordingly. - commit 9eafc8a ------------------------------------------------------------------- Tue Jun 13 15:51:42 CEST 2017 - nstange@suse.de - scripts/register-patches.sh: don't add ','s to @@KGR_PATCHES_FUNCS@@ register-patches.sh expands kgr_patch_main.c's @@KGR_PATCHES_FUNCS@@ placeholder by concatenating all available patches' KGR_PATCH_<XY>_FUNCS together, separating them by commas. The KGR_PATCH_<XY>_FUNCS are CPP macros supposed to be provided by each patch. If one of these happens to be empty, the preprocessed expansion will contain two consecutive commas which gcc doesn't like in array initializers. Do not add any commas to the @@KGR_PATCHES_FUNCS@@ expansion but require the individual KGR_PATCH_<XY>_FUNCS macros to already contain trailing ones as needed. Fixes: 4e8dc885be22 ("scripts: create kgr_patch_main.c dynamically") - commit ba41416 ------------------------------------------------------------------- Wed Jun 7 12:05:41 CEST 2017 - nstange@suse.de - scripts: create kgr_patch_main.c dynamically The kgraft-patches repository has got many branches, each corresponding to a supported codestream. Each of those carries a potentially different set of live (sub)patches which are controlled through the entry points in kgr_patch_main.c. According to Miroslav, merging of a new (sub)patch based on the pristine master is a pita due to conflicts. Since all (sub)patches stick to certain conventions already, the required modifications of the merging-hotspot kgr_patch_main.c are quite mechanic. Let a script do the work. Namely, - insert some special @@-embraced placeholders at the few places depending on the actual set of (sub)patches, - let register-patches.sh discover the available (sub)patches by searching for directories - and let register-patches.sh replace those placeholders in kgr_patch_main.c Finally, add a register-patches.sh invocation to tar-up.sh. This procedure requires that a SUBPATCH located in directory SUBPATCH/ adheres to the following conventions: - It must provide a provide a SUBPATCH/kgr_patch_SUBPATCH.h header. - This header must provide declarations for kgr_patch_SUBPATCH_init() and kgr_patch_SUBPATCH_cleanup(). - This header must also #define a KGR_PATCH_SUBPATCH_FUNCS macro. It should expand to a comma separated list of KGR_PATCH*() entries, each corresponding to a function the subpatch wants to replace.

The scripts is called from tar-up.sh or could be called manually. - commit 1af6c29 ------------------------------------------------------------------- Mon Oct 24 13:26:09 CEST 2016 - mbenes@suse.cz - Better to use SUSE:SLE-12:Update than Devel:kGraft:SLE12 project - commit bdc7598 ------------------------------------------------------------------- Tue May 10 15:43:59 CEST 2016 - mbenes@suse.cz - Add compat.h to deal with changes of KGR_PATCH macro Sympos patch set for kGraft redefined KGR_PATCH macro and added two new ones. Add new compat.h which contains macro magic so that all kGraft patches would work on both old and new kernels with the patch set merged. - commit 4186bef ------------------------------------------------------------------- Fri May 6 17:01:17 CEST 2016 - mbenes@suse.cz - Fix the number of parameters of KGR_PATCH macro New kernels contain kGraft's sympos patch set which changed number of paramaters of KGR_PATCH macro and introduced new macros. Fix it in master so it will be ok for new branches. - commit 78cf676 ------------------------------------------------------------------- Tue Sep 1 13:00:23 CEST 2015 - mmarek@suse.com - Include the RPM version number in the module name - commit 8fa02c6 ------------------------------------------------------------------- Wed Aug 26 11:29:44 CEST 2015 - mbenes@suse.cz - Remove forgotten debug option in the Makefile - commit 9c24ab8 ------------------------------------------------------------------- Mon Aug 17 13:42:04 CEST 2015 - mbenes@suse.cz - Add license and copyright notices - commit d42d3aa ------------------------------------------------------------------- Wed Jul 15 15:58:35 CEST 2015 - mbenes@suse.cz - Remove immediate flag Fake signal was merged to kGraft and immediate feature removed. Remove it in kGraft patches from now on too. - commit c767ad2 ------------------------------------------------------------------- Wed May 20 16:32:17 CEST 2015 - mbenes@suse.cz - Set immediate flag to false Using immediate set to true can lead to BUGs and oopses when downgrading, reverting or applying replace_all patches. There is no way how to find out if there is a process in the old code which is being removed. The module would be put, removed and the process will crash. The consistency model guarantees that there is no one in the old code when the finalization ends. Thus use it for all case to be safe. - commit 830e1a3 ------------------------------------------------------------------- Tue May 12 15:48:07 CEST 2015 - mbenes@suse.cz - Fix description in rpm spec file Spec file description mentions initial kGraft patch which is only true for real initial patch. Make it more neutral.

Also .immediate is there as a comment. - commit 933e15e ------------------------------------------------------------------- Mon Nov 24 15:02:33 CET 2014 - mmarek@suse.cz - Drop the hardcoded kernel release string The updated kgraft-devel macros set this during build time, so we do not need to know the kernel release string beforehand. As a name suffix for the source packages, let's use SLE12_Test in the master branch and SLE12_Update_<n> in the update branches. - commit 65f7a25 ------------------------------------------------------------------- Fri Nov 21 15:48:48 CET 2014 - mmarek@suse.cz - Check that we are building against the set kernel version - commit 689e44a ------------------------------------------------------------------- Wed Nov 12 04:11:14 CET 2014 - mmarek@suse.cz - Mark the module as supported References: bnc#904970 - commit 6249314 ------------------------------------------------------------------- Tue Nov 11 17:11:28 CET 2014 - mmarek@suse.cz - Build the test packages against Devel:kGraft:SLE12 - commit c952fbb ------------------------------------------------------------------- Thu Nov 6 13:55:43 CET 2014 - mbenes@suse.cz - Add top git commit hash to uname -v Add top git commit hash to version part of uname.
