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 ------------------------------------------------------------------- Tue Dec 5 16:42:04 CET 2017 - mbenes@suse.cz - uname_patch: fix UNAME26 for 4.0 Backport upstream commit 39afb5ee4640 ("kernel/sys.c: fix UNAME26 for 4.0"). - commit 5988feb ------------------------------------------------------------------- Mon Dec 4 15:25:24 CET 2017 - mbenes@suse.cz - Revert "Add compat.h to deal with changes of KGR_PATCH macro" This reverts commit 4186bef35862029a2fd36ba4a73d5fa538992709.

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__FUNCS together, separating them by commas. The KGR_PATCH__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__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.

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.
