2024-07-30Soong: BPF: Cflag and btf defaults Neill Kapron
Currently, all bpf programs require a cflags field which defines -Wall and -Werror. This change enables this by default, and also enables -Wextra. This removes boilerplate required for every bpf program, and improves code quality. Additionally, this change enables the default of 'btf: true' further reducing the boilerplate required for most bpf programs in their Android.bp file. BTF should be enabled by default, with only limited mainlined bpf programs requiring BTF being disabled for compatibility with older bpfloader releases.

2024-06-21Move vendor and product variant generation logic from cc package to android ↵ Jihoon Kang
package Although image variation generation logic has moved out of cc package to the android package, the vendor and product partition variants generation logic is still specific to cc package. Therefore, in order to create a product or vendor variant, they have to specified in `ExtraImageVariants`. In order to avoid such confusing behaviors and enforce modules to specify product and vendor installation rules, this change moves the vendor and product variant generation logic to android.ImageInterface.

2022-07-07Disallow '_' in bpf source name Ken Chen
Current design: 1. The bpf compiled object name is derived from the source name (e.g. foo.c -> foo.o). 2. Full bpf program/map name are concatenated by object name + '_' + program/map name in run-time. (e.g. obj name: x.o; program name: y_z; full bpf program name will be x_y_z) Issue: x.o with map y_z and x_y.o with map z can cause naming collision in run-time, since both result in x_y_z. This commit prevents it from happening with a build-time check. Bug: 236706995 Test: m Change-Id: Ic03bfcf07a5748ed63246b71d5ae8de0405e658a

2022-01-27Add option to generate BTF debug info for bpf programs Connor O'Brien
Add "btf" option that generates BTF debug info to support easier map inspection. This is accomplished by passing the "-g" flag to clang when compiling the BPF program. The "-g" option also generates a number of DWARF debug sections which are not necessary for loading BTF information, so strip these to avoid increasing file size unnecessarily. bpfloader currently only supports BTF info for maps, not programs, so we also strip the .BTF.ext section containing program BTF info.

2022-01-19Merge "[NETD-BPF#34] Add a tag for bpf to specify the install folder" Treehugger Robot
2022-01-19[NETD-BPF#34] Add a tag for bpf to specify the install folder Ken Chen
Currently, the bpf module netd.o (source system/netd/bpf_progs/netd.c) will be built to /system/etc/bpf/netd.o. In Android T, it will be moved to mainline module com.android.tethering. The expected behavior is: - In T device, it uses the netd.o in mainline module. - In pre-T devices, it uses the original netd, built from platform. However, netd.o will be double loaded if the tethering module is installed in Pre-T devices. Because: 1. bpf in apex is packed into /apex/MAINLINE_MODULE/etc/bpf/ 2. bpf in platform is packed into /system/etc/bpf/ 3. bpfloader in pre-T loads ANY bpf modules under /apex/com.android.tethering/etc/bpf/ and /system/etc/bpf/. We can't change the behavior of bpfloader in pre-T devices. We can't delete the /system/etc/bpf/netd.o from pre-T devices. Both of them are not mainline modules. So the mainlined netd.o needs to be packed into a folder other than /apex/com.android.tethering/etc/bpf/ or /system/etc/bpf/. This commit adds a tag 'sub_dir' for bpf module. The installation path of bpf modules will be: - /system/etc/bpf/SUB_DIR/ (for platform code) - /apex/MAINLINE_MODULE/etc/bpf/SUB_DIR/ (for mainline module) Bug: 202086915 Test: add test in apex_test.go and build Change-Id: Icc6619768ab006de9f86620a7df1bb2853eaba13
