So this makes\u000ausing C++ APIs for cgroup based networking applications\u000aeasier to integrate with bpf programs.\u000a\u000aThe unit testing is rough as it needs some work to set up\u000acgroups and establish TCP connections to really test the\u000aresult of map operations.

"comment" : "tools/stackcount: Fix address resolution for user-space stack\u000a\u000aThis patch fixes issue #2748. The bug was that address-to-symbol resolution\u000adidn't work for user-space stacks without the `-P` (per-pid) flag when tracing\u000asingle, isolated processes. The current documentation of the `-P` option\u000aindicates that it's used to \"display stacks separately for each process\",\u000aand this doesn't match with the intended usage.\u000a\u000aThis patch has two parts:\u000a\u000a - Fix `tools/stackcount.py` to explicitly set perpid to True if `-p `\u000a is used\u000a - Remove the `-P` option from the example of tracing single, isolated process\u000a in `tools/stackcount_example.txt`, since the usage of the option can\u000a be confusing (and unnecessary after the current change)\u000a",

"comment" : "usdt: fix parsing sp register in arguments on AArch64\u000a\u000aOne of the USDT probes for OpenJDK on AArch64 has an argument as an\u000aoffset from the stack pointer register like \"8@[sp, 112]\". This causes\u000athe argument parser to fail:\u000a\u000a Parse error:\u000a 8@x22 8@x20 8@x23 8@x0 8@x26 8@x27 8@[sp, 112] 8@[sp, 120]\u000a ------------------------------------------^\u000a\u000aThe error message then repeats forever.\u000a\u000aChanged ArgumentParser_aarch64::parse_register so it accepts either\u000a\"xNN\" or \"sp\" and outputs the register name rather than the register\u000anumber. The stack pointer is in a separate field `sp` in `struct\u000apt_regs` rather than in the `regs[]` array [1].\u000a\u000aNote that the parser currently accepts \"x31\" and converts that into a\u000areference to `regs[31]' but that array only has 31 elements. Made x31 an\u000aalias for `sp` to avoid undefined behaviour from reading past the end of\u000athe array.\u000a\u000a[1]: https://elixir.bootlin.com/linux/latest/source/arch/arm64/include/asm/ptrace.h#L160\u000a\u000aChange-Id: I88b6ff741914b5d06ad5798a55bd21ea03f69825\u000aSigned-off-by: Nick Gasson \u000a",

"comment" : "Translate virtual addresses to binary addresses for shared libs as well.\u000a\u000aQuoting https://refspecs.linuxbase.org/elf/elf.pdf:\u000a```\u000aSymbol table entries for different object file types have slightly different\u000ainterpretations for the st_value member.\u000a- In relocatable files, st_value holds alignment constraints for a symbol\u000awhose section index is SHN_COMMON.\u000a- In relocatable files, st_value holds a section offset for a defined symbol.\u000aThat is, st_value is an offset from the beginning of the section that st_shndx\u000aidentifies.\u000a- In executable and shared object files, st_value holds a virtual address. To\u000amake these files' symbols more useful for the dynamic linker, the section offset\u000a(file interpretation) gives way to a virtual address (memory interpretation) for\u000awhich the section number is irrelevant.\u000a```\u000a\u000aThis is a problem in practice as well. I run into this while tracing shared\u000alibraries on Android with bpftrace. Some of them have text sections mmapped\u000aat different offset than file offset which results in probes being placed\u000aat wrong offsets.\u000a",
