[PATCH v3] ksefltests: pidfd: Fix wait_states: Test terminated by timeout

by Li Zhijian

0Day/LKP observed that the kselftest blocks forever since one of the pidfd_wait doesn't terminate in 1 of 30 runs. After digging into the source, we found that it blocks at: ASSERT_EQ(sys_waitid(P_PIDFD, pidfd, &info, WCONTINUED, NULL), 0); wait_states has below testing flow: CHILD PARENT ---------------+-------------- 1 STOP itself 2 WAIT for CHILD STOPPED 3 SIGNAL CHILD to CONT 4 CONT 5 STOP itself 5' WAIT for CHILD CONT 6 WAIT for CHILD STOPPED The problem is that the kernel cannot ensure the order of 5 and 5', once 5 goes first, the test will fail. we can reproduce it by: $ while true; do make run_tests -C pidfd; done Introduce a blocking read in child process to make sure the parent can check its WCONTINUED.

[PATCH RESEND v4 00/23] SMM emulation and interrupt shadow fixes

by Maxim Levitsky

This patch series is a result of long debug work to find out why sometimes guests with win11 secure boot were failing during boot. During writing a unit test I found another bug, turns out that on rsm emulation, if the rsm instruction was done in real or 32 bit mode, KVM would truncate the restored RIP to 32 bit. I also refactored the way we write SMRAM so it is easier now to understand what is going on. The main bug in this series which I fixed is that we allowed #SMI to happen during the STI interrupt shadow, and we did nothing to both reset it on #SMI handler entry and restore it on RSM. V4: - rebased on top of patch series from Paolo which allows smm support to be disabled by Kconfig option. - addressed review feedback. I included these patches in the series for reference. Best regards, Maxim Levitsky Maxim Levitsky (15): bug: introduce ASSERT_STRUCT_OFFSET KVM: x86: emulator: em_sysexit should update ctxt->mode KVM: x86: emulator: introduce emulator_recalc_and_set_mode KVM: x86: emulator: update the emulation mode after rsm KVM: x86: emulator: update the emulation mode after CR0 write KVM: x86: smm: number of GPRs in the SMRAM image depends on the image format KVM: x86: smm: check for failures on smm entry KVM: x86: smm: add structs for KVM's smram layout KVM: x86: smm: use smram structs in the common code KVM: x86: smm: use smram struct for 32 bit smram load/restore KVM: x86: smm: use smram struct for 64 bit smram load/restore KVM: svm: drop explicit return value of kvm_vcpu_map KVM: x86: SVM: use smram structs KVM: x86: SVM: don't save SVM state to SMRAM when VM is not long mode capable KVM: x86: smm: preserve interrupt shadow in SMRAM Paolo Bonzini (8): KVM: x86: start moving SMM-related functions to new files KVM: x86: move SMM entry to a new file KVM: x86: move SMM exit to a new file KVM: x86: do not go through ctxt->ops when emulating rsm KVM: allow compiling out SMM support KVM: x86: compile out vendor-specific code if SMM is disabled KVM: x86: remove SMRAM address space if SMM is not supported KVM: x86: do not define KVM_REQ_SMI if SMM disabled arch/x86/include/asm/kvm-x86-ops.h | 2 + arch/x86/include/asm/kvm_host.h | 29 +- arch/x86/kvm/Kconfig | 11 + arch/x86/kvm/Makefile | 1 + arch/x86/kvm/emulate.c | 458 +++---------- arch/x86/kvm/kvm_cache_regs.h | 5 - arch/x86/kvm/kvm_emulate.h | 47 +- arch/x86/kvm/lapic.c | 14 +- arch/x86/kvm/lapic.h | 7 +- arch/x86/kvm/mmu/mmu.c | 1 + arch/x86/kvm/smm.c | 637 ++++++++++++++++++ arch/x86/kvm/smm.h | 160 +++++ arch/x86/kvm/svm/nested.c | 3 + arch/x86/kvm/svm/svm.c | 43 +- arch/x86/kvm/vmx/nested.c | 1 + arch/x86/kvm/vmx/vmcs12.h | 5 +- arch/x86/kvm/vmx/vmx.c | 11 +- arch/x86/kvm/x86.c | 353 +--------- include/linux/build_bug.h | 9 + tools/testing/selftests/kvm/x86_64/smm_test.c | 2 + 20 files changed, 1031 insertions(+), 768 deletions(-) create mode 100644 arch/x86/kvm/smm.c create mode 100644 arch/x86/kvm/smm.h -- 2.34.3

[PATCH v13 0/2] Introduce XSAVE feature self-test

by Pengfei Xu

The XSAVE feature set supports the saving and restoring of xstate components. XSAVE feature has been used for process context switching. XSAVE components include x87 state for FP execution environment, SSE state, AVX state and so on. In order to ensure that XSAVE works correctly, add XSAVE most basic test for XSAVE architecture functionality. This patch tests "FP, SSE(XMM), AVX2(YMM), AVX512_OPMASK/AVX512_ZMM_Hi256/ AVX512_Hi16_ZMM and PKRU parts" xstates with following cases: 1. The contents of these xstates in the process should not change after the signal handling. 2. The contents of these xstates in the child process should be the same as the contents of the xstate in the parent process after the fork syscall. 3. The contents of xstates in the parent process should not change after the context switch. As stated in the ABI(Application Binary Interface) specification: https://refspecs.linuxbase.org/elf/x86_64-abi-0.99.pdf Xstate like XMM is not preserved across function calls, so fork() function which provided from libc could not be used in the xsave test, and the libc function is replaced with an inline function of the assembly code only. To prevent GCC from generating any FP/SSE(XMM)/AVX/PKRU code by mistake, add "-mno-sse -mno-mmx -mno-sse2 -mno-avx -mno-pku" compiler arguments. stdlib.h can not be used because of the "-mno-sse" option. Thanks Dave, Hansen for the above suggestion! Thanks Chen Yu; Shuah Khan; Chatre Reinette and Tony Luck's comments! Thanks to Bae, Chang Seok for a bunch of comments! ======== - Change from v12 to v13 - Improve the comments of CPUID.(EAX=0DH, ECX=0H):EBX. - Change from v11 to v12 - Remove useless rbx register stuffing in assembly syscall functions. (Zhang, Li) - Change from v10 to v11 - Remove the small function like cpu_has_pkru(), get_xstate_size() and so on. (Shuah Khan) - Unify xfeature_num type to uint32_t. - Change from v9 to v10 - Remove the small function if the function will be called once and there is no good reason. (Shuah Khan) - Change from v8 to v9 - Use function pointers to make it more structured. (Hansen, Dave) - Improve the function name: xstate_tested -> xstate_in_test. (Chang S. Bae) - Break this test up into two pieces: keep the xstate key test steps with "-mno-sse" and no stdlib.h, keep others in xstate.c file. (Hansen, Dave) - Use kselftest infrastructure for xstate.c file. (Hansen, Dave) - Use instruction back to populate fp xstate buffer. (Hansen, Dave) - Will skip the test if cpu could not support xsave. (Chang S. Bae) - Use __cpuid_count() helper in kselftest.h. (Reinette, Chatre) - Change from v7 to v8 Many thanks to Bae, Chang Seok for a bunch of comments as follow: - Use the filling buffer way to prepare the xstate buffer, and use xrstor instruction way to load the tested xstates. - Remove useless dump_buffer, compare_buffer functions. - Improve the struct of xstate_info. - Added AVX512_ZMM_Hi256 and AVX512_Hi16_ZMM components in xstate test. - Remove redundant xstate_info.xstate_mask, xstate_flag[], and xfeature_test_mask, use xstate_info.mask instead. - Check if xfeature is supported outside of fill_xstate_buf() , this change is easier to read and understand. - Remove useless wrpkru, only use filling all tested xstate buffer in fill_xstates_buf(). - Improve a bunch of function names and variable names. - Improve test steps flow for readability. - Change from v6 to v7: - Added the error number and error description of the reason for the failure, thanks Shuah Khan's suggestion. - Added a description of what these tests are doing in the head comments. - Added changes update in the head comments. - Added description of the purpose of the function. thanks Shuah Khan. - Change from v5 to v6: - In order to prevent GCC from generating any FP code by mistake, "-mno-sse -mno-mmx -mno-sse2 -mno-avx -mno-pku" compiler parameter was added, it's referred to the parameters for compiling the x86 kernel. Thanks Dave Hansen's suggestion. - Removed the use of "kselftest.h", because kselftest.h included <stdlib.h>, and "stdlib.h" would use sse instructions in it's libc, and this *XSAVE* test needed to be compiled without libc sse instructions(-mno-sse). - Improved the description in commit header, thanks Chen Yu's suggestion. - Becasue test code could not use buildin xsave64 in libc without sse, added xsave function by instruction way. - Every key test action would not use libc(like printf) except syscall until it's failed or done. If it's failed, then it would print the failed reason. - Used __cpuid_count() instead of native_cpuid(), becasue __cpuid_count() was a macro definition function with one instruction in libc and did not change xstate. Thanks Chatre Reinette, Shuah Khan. https://lore.kernel.org/linux-sgx/8b7c98f4-f050-bc1c-5699-fa598ecc66a2@linu… - Change from v4 to v5: - Moved code files into tools/testing/selftests/x86. - Delete xsave instruction test, becaue it's not related to kernel. - Improved case description. - Added AVX512 opmask change and related XSAVE content verification. - Added PKRU part xstate test into instruction and signal handling test. - Added XSAVE process swich test for FPU, AVX2, AVX512 opmask and PKRU part. - Change from v3 to v4: - Improve the comment in patch 1. - Change from v2 to v3: - Improve the description of patch 2 git log. - Change from v1 to v2: - Improve the cover-letter.

[PATCH] selftests/nolibc: always rebuild the sysroot when running a test

by Willy Tarreau

Paul and myself got trapped a few times by not seeing the effects of applying a patch to the nolibc source code until a "make clean" was issued in the nolibc directory. It's particularly annoying when trying to confirm that a proposed patch really solves a problem (or that reverting it reintroduces the problem). The reason for the sysroot not being rebuilt was that it can be quite slow. But in fact it's only slow after a "make clean" issued at the kernel's topdir, because it's the main "make headers" that can take a tens of seconds; as long as "usr/include" still contains headers, the "headers_install" phase is only a quick "rsync", and rebuilding the whole nolibc sysroot takes a bit less than one second, which is perfectly acceptable for a test, even more once the time lost caused by misleading results if factored in. This patch marks the sysroot target as phony and starts by clearing the previous sysroot for the current architecture before reinstalling it. Thanks to this, applying a patch to nolibc makes the effect immediately visible to "make nolibc-test": $ time make -j -C tools/testing/selftests/nolibc nolibc-test make: Entering directory '/k/tools/testing/selftests/nolibc' MKDIR sysroot/x86/include make[1]: Entering directory '/k/tools/include/nolibc' make[2]: Entering directory '/k' make[2]: Leaving directory '/k' make[2]: Entering directory '/k' INSTALL /k/tools/testing/selftests/nolibc/sysroot/sysroot/include make[2]: Leaving directory '/k' make[1]: Leaving directory '/k/tools/include/nolibc' CC nolibc-test make: Leaving directory '/k/tools/testing/selftests/nolibc' real 0m0.869s user 0m0.716s sys 0m0.149s Cc: "Paul E.

[PATCH] selftests/nolibc: add 7 tests for memcmp()

by Willy Tarreau

This adds 7 combinations of input values for memcmp() using signed and unsigned bytes, which will trigger on the original code before Rasmus' fix. This is mostly aimed at helping backporters verify their work, and showing how tests for corner cases can be added to the selftests suite. Before the fix it reports: 12 memcmp_20_20 = 0 [OK] 13 memcmp_20_60 = -64 [OK] 14 memcmp_60_20 = 64 [OK] 15 memcmp_20_e0 = 64 [FAIL] 16 memcmp_e0_20 = -64 [FAIL] 17 memcmp_80_e0 = -96 [OK] 18 memcmp_e0_80 = 96 [OK] And after: 12 memcmp_20_20 = 0 [OK] 13 memcmp_20_60 = -64 [OK] 14 memcmp_60_20 = 64 [OK] 15 memcmp_20_e0 = -192 [OK] 16 memcmp_e0_20 = 192 [OK] 17 memcmp_80_e0 = -96 [OK] 18 memcmp_e0_80 = 96 [OK] Cc: Rasmus Villemoes <linux(a)rasmusvillemoes.dk> Signed-off-by: Willy Tarreau <w(a)1wt.eu> --- tools/testing/selftests/nolibc/nolibc-test.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/tools/testing/selftests/nolibc/nolibc-test.c b/tools/testing/selftests/nolibc/nolibc-test.c index 78bced95ac63..f14f5076fb6d 100644 --- a/tools/testing/selftests/nolibc/nolibc-test.c +++ b/tools/testing/selftests/nolibc/nolibc-test.c @@ -565,6 +565,13 @@ int run_stdlib(int min, int max) CASE_TEST(strchr_foobar_z); EXPECT_STRZR(1, strchr("foobar", 'z')); break; CASE_TEST(strrchr_foobar_o); EXPECT_STREQ(1, strrchr("foobar", 'o'), "obar"); break; CASE_TEST(strrchr_foobar_z); EXPECT_STRZR(1, strrchr("foobar", 'z')); break; + CASE_TEST(memcmp_20_20); EXPECT_EQ(1, memcmp("aaa\x20", "aaa\x20", 4), 0); break; + CASE_TEST(memcmp_20_60); EXPECT_LT(1, memcmp("aaa\x20", "aaa\x60", 4), 0); break; + CASE_TEST(memcmp_60_20); EXPECT_GT(1, memcmp("aaa\x60", "aaa\x20", 4), 0); break; + CASE_TEST(memcmp_20_e0); EXPECT_LT(1, memcmp("aaa\x20", "aaa\xe0", 4), 0); break; + CASE_TEST(memcmp_e0_20); EXPECT_GT(1, memcmp("aaa\xe0", "aaa\x20", 4), 0); break; + CASE_TEST(memcmp_80_e0); EXPECT_LT(1, memcmp("aaa\x80", "aaa\xe0", 4), 0); break; + CASE_TEST(memcmp_e0_80); EXPECT_GT(1, memcmp("aaa\xe0", "aaa\x80", 4), 0); break; case __LINE__: return ret; /* must be last */ /* note: do not set any defaults so as to permit holes above */ -- 2.17.5

[PATCH v9 0/9] x86: Show in sysfs if a memory node is able to do encryption

by Martin Fernandez

Show for each node if every memory descriptor in that node has the EFI_MEMORY_CPU_CRYPTO attribute. fwupd project plans to use it as part of a check to see if the users have properly configured memory hardware encryption capabilities. fwupd's people have seen cases where it seems like there is memory encryption because all the hardware is capable of doing it, but on a closer look there is not, either because of system firmware or because some component requires updating to enable the feature. The MKTME/TME spec says that it will only encrypt those memory regions which are flagged with the EFI_MEMORY_CPU_CRYPTO attribute. If all nodes are capable of encryption and if the system have tme/sme on we can pretty confidently say that the device is actively encrypting all its memory. It's planned to make this check part of an specification that can be passed to people purchasing hardware These checks will run at every boot. The specification is called Host Security ID: https://fwupd.github.io/libfwupdplugin/hsi.html. We choosed to do it a per-node basis because although an ABI that shows that the whole system memory is capable of encryption would be useful for the fwupd use case, doing it in a per-node basis would make the path easier to give the capability to the user to target allocations from applications to NUMA nodes which have encryption capabilities in the future. Changes since v8: Add unit tests to e820_range_* functions Changes since v7: Less kerneldocs Less verbosity in the e820 code Changes since v6: Fixes in __e820__handle_range_update Const correctness in e820.c Correct alignment in memblock.h Rework memblock_overlaps_region Changes since v5: Refactor e820__range_{update, remove, set_crypto_capable} in order to avoid code duplication. Warn the user when a node has both encryptable and non-encryptable regions. Check that e820_table has enough size to store both current e820_table and EFI memmap. Changes since v4: Add enum to represent the cryptographic capabilities in e820: e820_crypto_capabilities. Revert __e820__range_update, only adding the new argument for __e820__range_add about crypto capabilities. Add a function __e820__range_update_crypto similar to __e820__range_update but to only update this new field. Changes since v3: Update date in Doc/ABI file. More information about the fwupd usecase and the rationale behind doing it in a per-NUMA-node. Changes since v2: e820__range_mark_crypto -> e820__range_mark_crypto_capable. In e820__range_remove: Create a region with crypto capabilities instead of creating one without it and then mark it. Changes since v1: Modify __e820__range_update to update the crypto capabilities of a range; now this function will change the crypto capability of a range if it's called with the same old_type and new_type. Rework efi_mark_e820_regions_as_crypto_capable based on this. Update do_add_efi_memmap to mark the regions as it creates them. Change the type of crypto_capable in e820_entry from bool to u8. Fix e820__update_table changes. Remove memblock_add_crypto_capable. Now you have to add the region and mark it then. Better place for crypto_capable in pglist_data.

[PATCH v2 net 0/2] openvswitch: syzbot splat fix and introduce selftest

by Aaron Conole

Syzbot recently caught a splat when dropping features from openvswitch datapaths that are in-use. The WARN() call is definitely too large a hammer for the situation, so change to pr_warn. Second patch in the series introduces a new selftest suite which can help show that an issue is fixed. This change might be more suited to net-next tree, so it has been separated out as an additional patch and can be either applied to either tree based on preference.

[PATCH v7 0/3] Introduce KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ macros

by Maíra Canal

Currently, in order to compare memory blocks in KUnit, the KUNIT_EXPECT_EQ or KUNIT_EXPECT_FALSE macros are used in conjunction with the memcmp function, such as: KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0); Although this usage produces correct results for the test cases, if the expectation fails the error message is not very helpful, indicating only the return of the memcmp function. Therefore, create a new set of macros KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ that compare memory blocks until a determined size. In case of expectation failure, those macros print the hex dump of the memory blocks, making it easier to debug test failures for memory blocks. The v7 has some formatting changes on the first patch and it was rebased on top of the mainline (due to 7089003304c6). The first patch of the series introduces the KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ. The second patch adds an example of memory block expectations on the kunit-example-test.c. And the last patch replaces the KUNIT_EXPECT_EQ for KUNIT_EXPECT_MEMEQ on the existing occurrences.

[PATCH] selftests: vm: use 1 MB hugepage size for s390

by Gerald Schaefer

hugepage-vmemmap test fails for s390 because it assumes a hugepagesize of 2 MB, while we have 1 MB on s390. This results in iterating over two hugepages. If they are consecutive in memory, check_page_flags() will stumble over the additional head page. Otherwise, it will stumble over non-huge pageflags, after crossing the first 1 MB hugepage. Fix this by using 1 MB MAP_LENGTH for s390.

[PATCH v2 1/3] kunit: Provide a static key to check if KUnit is actively running tests

by David Gow

KUnit does a few expensive things when enabled. This hasn't been a problem because KUnit was only enabled on test kernels, but with a few people enabling (but not _using_) KUnit on production systems, we need a runtime way of handling this. Provide a 'kunit_running' static key (defaulting to false), which allows us to hide any KUnit code behind a static branch. This should reduce the performance impact (on other code) of having KUnit enabled to a single NOP when no tests are running. Note that, while it looks unintuitive, tests always run entirely within __kunit_test_suites_init(), so it's safe to decrement the static key at the end of this function, rather than in __kunit_test_suites_exit(), which is only there to clean up results in debugfs. Signed-off-by: David Gow <davidgow(a)google.com> --- This should be a no-op (other than a possible performance improvement) functionality-wise, and lays the groundwork for a more optimised static stub implementation. The remaining patches in the series add a kunit_get_current_test() function which is a more friendly and performant wrapper around current->kunit_test, and use this in the slub test. They also improve the documentation a bit. If there are no objections, we'll take the whole series via the KUnit tree.

[PATCH] Documentation: kunit: Remove redundant 'tips.rst' page

by David Gow

The contents of 'tips.rst' was included in 'usage.rst' way back in commit 953574390634 ("Documentation: KUnit: Rework writing page to focus on writing tests"), but the tips page remained behind as well. Therefore, delete 'tips.rst' While I regret breaking any links to 'tips' which might exist externally, it's confusing to have two subtly different versions of the same content around.

[PATCH 0/4] mm/damon/reclaim,lru_sort: enable/disable synchronously

by SeongJae Park

Writing a value to DAMON_RECLAIM and DAMON_LRU_SORT's 'enabled' parameters turns on or off DAMON in an ansychronous way. This means the parameter cannot be used to read the current status of them. 'kdamond_pid' parameter should be used instead for the purpose. The documentation is easy to be read as it works in a synchronous way, so it is a little bit confusing. It also makes the user space tooling dirty. There's no real reason to have the asynchronous behavior, though. Simply make the parameter works synchronously, rather than updating the document. The first and second patches changes the behavior of the 'enabled' parameter for DAMON_RECLAIM and adds a selftest for the changed behavior, respectively. Following two patches make the same changes for DAMON_LRU_SORT. SeongJae Park (4): mm/damon/reclaim: enable and disable synchronously selftests/damon: add tests for DAMON_RECLAIM's enabled parameter mm/damon/lru_sort: enable and disable synchronously selftests/damon: add tests for DAMON_LRU_SORT's enabled parameter mm/damon/lru_sort.c | 51 ++++++++++------------ mm/damon/reclaim.c | 53 ++++++++++------------- tools/testing/selftests/damon/Makefile | 1 + tools/testing/selftests/damon/lru_sort.sh | 41 ++++++++++++++++++ tools/testing/selftests/damon/reclaim.sh | 42 ++++++++++++++++++ 5 files changed, 129 insertions(+), 59 deletions(-) create mode 100755 tools/testing/selftests/damon/lru_sort.sh create mode 100755 tools/testing/selftests/damon/reclaim.sh -- 2.25.1

[PATCH v4 00/23] SMM emulation and interrupt shadow fixes

by Maxim Levitsky

This patch series is a result of long debug work to find out why sometimes guests with win11 secure boot were failing during boot. During writing a unit test I found another bug, turns out that on rsm emulation, if the rsm instruction was done in real or 32 bit mode, KVM would truncate the restored RIP to 32 bit. I also refactored the way we write SMRAM so it is easier now to understand what is going on. The main bug in this series which I fixed is that we allowed #SMI to happen during the STI interrupt shadow, and we did nothing to both reset it on #SMI handler entry and restore it on RSM. V4: - rebased on top of patch series from Paolo which allows smm support to be disabled by Kconfig option. - addressed review feedback. I included these patches in the series for reference.

[PATCH net 0/2] openvswitch: syzbot splat fix and introduce selftest

by Aaron Conole

Syzbot recently caught a splat when dropping features from openvswitch datapaths that are in-use. The WARN() call is definitely too large a hammer for the situation, so change to pr_warn. Second patch in the series introduces a new selftest suite which can help show that an issue is fixed. This change might be more suited to net-next tree, so it has been separated out as an additional patch and can be either applied to either tree based on preference.

[PATCH v1 0/7] selftests/vm: test COW handling of anonymous memory

by David Hildenbrand

On top of mm-stable. This is my current set of tests for testing COW handling of anonymous memory, especially when interacting with GUP. I developed these tests while working on PageAnonExclusive and managed to clean them up just now. On current upstream Linux, all tests pass except the hugetlb tests that rely on vmsplice -- these tests should pass as soon as vmsplice properly uses FOLL_PIN instead of FOLL_GET. I'm working on additional tests for COW handling in private mappings, focusing on long-term R/O pinning e.g., of the shared zeropage, pagecache pages and KSM pages. These tests, however, will go into a different file. So this is everything I have regarding tests for anonymous memory.

[PATCH v15 0/3]] Add TDX Guest Attestation support

by Kuppuswamy Sathyanarayanan

Hi All, Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. VM guest with TDX support is called as a TDX Guest. In TDX guest, attestation process is used to verify the TDX guest trustworthiness to other entities before provisioning secrets to the guest. For example, a key server may request for attestation before releasing the encryption keys to mount the encrypted rootfs or secondary drive. This patch set adds attestation support for the TDX guest. Details about the TDX attestation process and the steps involved are explained in Documentation/x86/tdx.rst (added by patch 2/3). Following are the details of the patch set: Patch 1/3 -> Preparatory patch for adding attestation support. Patch 2/3 -> Adds user interface driver to support attestation. Patch 3/3 -> Adds selftest support for TDREPORT feature. Commit log history is maintained in the individual patches.
