Soong doesn't have propagation for static library dependencies. Add "elfutils_transitive_defaults" to have "static_libs" that are applied to all static libraries that use elfutils. This have to be included explicitly by all elfutils users. Bug: 169779783 Bug: 309972007 Change-Id: I635b0f1eeee574fa27b44fe99a73439ec62c0066 Signed-off-by: Aleksei Vetrov <vvvvvv@google.com>

2023-10-05ksnoop: use bpf_get_func_ip() where helper is availableAlan Maguire
bpf_get_func_ip(ctx) will get the function address; use it where available using the BPF core enum value check for the function. This avoids needing to get the caller IP via KSNOOP_IP_FIX() for more up-to-date kernels. This fixes issue #4746 for kernels newer than 5.13; an additional followup will be needed to address this for older kernels. Kindly tested by https://github.com/matthew-olson-intel on a recent kernel. Reported-by: dubeyabhishek (https://github.com/dubeyabhishek) Signed-off-by: Alan Maguire <alan.maguire@oracle.com>

2023-08-31cc: remove a spurious check for UID 0Luca BRUNO
This drops an hardcoded check for the root user-ID before accessing `/proc/kallsyms`, in order to fix a bug which is preventing proper kernel symbols resolution by non-root users. The `/proc/kallsyms` file is generally available to non-privileged users: ``` > runuser -u nobody -- wc -l /proc/kallsyms 217514 /proc/kallsyms ``` Its content is further controlled by the `CAP_SYSLOG` capability through `/proc/sys/kernel/kptr_restrict`: https://man7.org/linux/man-pages/man7/capabilities.7.html As such, it is better to directly open it and rely on `fopen()` for privileges checking.
2023-08-31Allow for installing python as a non-system packageLee Avital
Debian's python, unlike stock python, expects system packages to be installed in `/usr/local/lib/python3.X/dist-packages/` and not `/usr/local/lib/python3.X/site-packages/`. As such debian's python setuptools has a flag `--install-layout deb` which places library files in the correct place. `src/python/CMakeLists.txt` checks if the system is debian and adds this flag. However, if you're trying to use BCC with a non-system version of python (for example miniconda) the different package layout (and setuptools flag) aren't there. Also, libraries aren't expected to be placed in /usr, but whatever prefix the alternative python install is using. This PR adds two flags to the CMAke build: * PY_SKIP_DEB_LAYOUT - which skips adding the `--install-layout deb` flag to the python install command * PYTHON_PREFIX which (if set) takes the place of CMAKE_INSTALL_PREFIX as a target for installing python packages Both are needed to allow installing python bindings into python installs that aren't the system install on debian hosts. For example, for a miniconda install on ubuntu: With this PR, I can get a working install with miniconda on ubuntu 22 using: ``` cmake .. -DPY_SKIP_DEB_LAYOUT=true -DPYTHON_PREFIX=/home/vagrant/miniconda3/envs/ddpy3/ ```
