OpenWrt Support - Githubissues

PolynomialDivision commented 4 years ago

I try to cross-compile your tool for OpenWrt. Since u use reallocarray and similar functions you enable #define _GNU_SOURCE. I would assume that everyhing is correct, but it still fails to compile.

params.c: In function 'handle_multistring':
params.c:58:8: error: implicit declaration of function 'reallocarray'; did you mean 'realloc'? [-Werror=implicit-function-declaration]
  ptr = reallocarray(opt_set->strings, sizeof(*opt_set->strings),
        ^~~~~~~~~~~~
        realloc
params.c:58:6: error: assignment to 'void *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
  ptr = reallocarray(opt_set->strings, sizeof(*opt_set->strings),

PolynomialDivision commented 4 years ago

Maybe I know why this happens, OpenWrt uses another stripped libc.

tohojo commented 4 years ago

Hmm, openwrt uses musl by default, so presumably that's why? No great objection to replacing reallocarray with something else, so feel free to fix that and open a PR :)

PolynomialDivision commented 4 years ago

I first try to compile it with glibc. ;)

Now I have the same issues in libbpf... ^^

Well you could create a separate package for libbpf and add a patch there? We probably want to package libbpf separately for openwrt anyway so we can use it for, say, iproute2, so this could be a start for that?

PolynomialDivision commented 4 years ago

There is already a libbpf package.

libbpf support: system v0.0.9

But if I want to use it, I get the following error. :/

tohojo commented 4 years ago

Hmm, maybe something is wrong with that package? Does the libbpf package install bpf_helpers.h ?

tohojo commented 4 years ago

Ah, wait, or maybe you just need to set BPF_CFLAGS properly for cross-compilation?

PolynomialDivision commented 4 years ago

Yes it installs it under: /home/nick/openwrt/staging_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/usr/include/bpf

PolynomialDivision commented 4 years ago

Just adding echo "CFLAGS += -I/home/nick/openwrt/staging_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/usr/include" >$CONFIG is fixing for now... But now I have other issues.

PolynomialDivision commented 4 years ago

Now I'm stucked with a linker issues:

PolynomialDivision commented 4 years ago

The lib contains the needed symbols.

Have a look at how we set all the variables (before configure) in the RPM .spec file:

https://github.com/xdp-project/xdp-tools/blob/master/packaging/rpm/xdp-tools.spec

Make sure you do all of that; does OpenWrt have LLVM as part of the environment?

PolynomialDivision commented 4 years ago

Make sure you do all of that;

Okay, I will try.

OpenWrt have LLVM as part of the environment?

I don't think so. I aways cross-compiled bpf things with clang.

Thanks again for all your help! :)

PolynomialDivision commented 4 years ago

Just for clarification. Actually, I think I only the the xdp-loader to work. I already cross-compiled the tutorial xdp-loader somehow but using it resulted in failures. Then I can go for the other bpf-stuff. ;)

Sure, but you still need a working libbpf for that...

This sounds like libbpf is having trouble parsing netlink messages. Endianness issue perhaps?

PolynomialDivision commented 3 years ago

Endianness issue perhaps?

Hmmmm. I will have a look. But the libbpf library is not compiled from me, or? It is installed from the package sources of the opkg repro. So why should the endianess be a problem?

Any idea why I can not use the loader? Why I always get the helptext?

PolynomialDivision commented 3 years ago

This sounds like libbpf is having trouble parsing netlink messages.

Maybe it is build against the wrong libbpf version, since you checkout an own libbpf version in your makefiles?

I will have a look.

That should be obvious in the configure output (libbpf: system vs libbpf: submodule). It should work fine with the system (shipped) libbpf version, which it kinda does, except that libbpf itself is outputting those error messages...

It does seem a bit odd. From the man page:

ERRORS calloc(), malloc(), realloc(), and reallocarray() can fail with the following error:

   ENOMEM Out of memory.  Possibly, the application hit the RLIMIT_AS or RLIMIT_DATA limit described in getrlimit(2).

Do you have a really small limit set? Try 'ulimit -a' and see if anything looks odd...

Another possibility is that realloc() is broken in musl or something...

Maybe I did something wrong, but the opt_set->num_strings +1 has abitary huge values that are random, e.g. 2010776721 with a constant value of SIZE_MAX / sizeof(*opt_set->strings) 1073741823. At my local pc the num_strings + 1 is always 1, like I would expect.

Maybe I did something wrong, but the opt_set->num_strings +1 has abitary huge values that are random, e.g. 2010776721 with a constant value of SIZE_MAX / sizeof(*opt_set->strings) 1073741823. At my local pc the num_strings + 1 is always 1, like I would expect.

Hmm, I guess the struct initialisation is not properly zeroing the nested struct. Which version of GCC is your build system using?

If I I init it with opt_set->num_strings with 0, I get to the following point

Could you try running with -vv and see if you get some more error output? I fear we may be in 'kernel too old' territory here, though; what kernel version are you running?

In any case it shouldn't segfault... If you can get a backtrace from gdb that would be awesome, otherwise I can try digging from the debug output...

. Which version of GCC is your build system using?

gcc 8.4.0

I can try a newer version. ;)

I will try to compile with gcc 10. But this always takes some time. ;)

Well, we need to fix this for old GCC anyway, I'll try to reproduce...

Did not change anything (so tried with gcc 10 now).

PolynomialDivision commented 3 years ago

I hope the 5.10 kernel will be soon available for OpenWrt. ;)

I will try compiling for x86 architecture OpenWrt. Let's see if this will help.

On x86_64 it looks much better. ;) But somehow it uses my host libs. I have to check that again. ^^

I'm now maintaining here a package feed: https://github.com/PolynomialDivision/openwrt-xdp-tools Interesting is that

libbpf: Error in bpf_object__probe_loading():Operation not permitted(1). Couldn't load trivial BPF program. Make sure your kernel supports BPF (CONFIG_BPF_SYSCALL=y) and/or that RLIMIT_MEMLOCK is set to big enough value.

I will have a look again at my BPF kernel config...
