4Subject: [PATCH] Replace kprobe function "blk_account_io_completion" to
5 "blk_account_io_done" for kernel version >= 5.8.0
6
7The kernel function "blk_account_io_completion" is not available anymore as attach point of Kprobe as of kernel version 5.8.0. Therefore, after discussions, we decided to use function "blk_account_io_done" instead in every kprobe attachment to "blk_account_io_completion".

4Subject: [PATCH 1/3] cmake: link dynamically to libclang-cpp if found and
5 ENABLE_LLVM_SHARED is set
6
7ENABLE_LLVM_SHARED allows to dynamically link against libLLVM, but
8libclang is still unconditionally linked statically.
9Search for libclang-cpp.so, and if it is found and ENABLE_LLVM_SHARED
10is set dynamically link against it.
11Also expand the libstdc++ static linking check to include this new
12condition.

4Subject: [PATCH 1/2] fix compilation issues with latest llvm12 trunk
5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
9With latest llvm12 trunk, we got two compilation bugs.
10
11Bug #1:
12 /home/yhs/work/bcc/src/cc/frontends/clang/b_frontend_action.cc:
13 In member function ‘void ebpf::BFrontendAction::DoMiscWorkAround()’:
14 /home/yhs/work/bcc/src/cc/frontends/clang/b_frontend_action.cc:1706:31:
15 error: ‘class clang::SourceManage’ has no member named ‘getBuffer’; did you mean ‘getBufferData’?
16 rewriter_->getSourceMgr().getBuffer(rewriter_->getSourceMgr().getMainFileID())->getBufferSize(),
17 ^~~~~~~~~
18 getBufferData
19
20 This is due to upstream change https://reviews.llvm.org/D89394.
21 To fix, follow upstream examples in https://reviews.llvm.org/D89394.
22
23Bug #2:
24 /home/yhs/work/bcc/src/cc/bpf_module.cc: In member function ‘int ebpf::BPFModule::finalize()’:
25 /home/yhs/work/bcc/src/cc/bpf_module.cc:470:11:
26 error: ‘class llvm::EngineBuilder’ has no member named ‘setUseOrcMCJITReplacement’
27 builder.setUseOrcMCJITReplacement(false);
28 ^~~~~~~~~~~~~~~~~~~~~~~~~
29
30 This is due to upstream
31 https://github.com/llvm/llvm-project/commit/6154c4115cd4b78d0171892aac21e340e72e32bd
32
33 It seems builder.setUseOrcMCJITReplacement() is not needed any more. So just remove it
34 from bcc.

4Subject: [PATCH 2/3] cmake: always link to packaged libbpf if
5 CMAKE_USE_LIBBPF_PACKAGE is set (#3210)
6
7Some of the executables still link to the local static versions
8even if the user requested CMAKE_USE_LIBBPF_PACKAGE. Fix this by
9using bcc-shared-no-libbpf more widely if the variable is set.
10
11Skip the git submodule and the extraction commands if the user
12set CMAKE_USE_LIBBPF_PACKAGE

21This is due to llvm patch https://reviews.llvm.org/D78793 which
22changed how to use getTypeByName(). This patch adjusted the usage
23in bcc based on this patch.

4Subject: [PATCH 3/3] Remove libbcc-no-libbpf shared library, change libbcc
5 linkage instead
6
7The current upstream split does not work very well, as the SONAME is mangled so
8nothing recognises it. Applications link against libbcc, not libbcc_no_bpf.
9Remove it entirely, and switch the libbcc.so to dynamically
10link with libbpf if CMAKE_USE_LIBBPF_PACKAGE is set.
