I got a strange error on ARM to fail on processing FINISHED_ROUND record. It turned out that it was failing in symbol__alloc_hist() because the symbol size is too big. When a sample is captured on a specific BPF program, it failed. I've added a debug code and found the end address of the symbol is from the next module which is placed far way. ffff800008795778-ffff80000879d6d8: bpf_prog_1bac53b8aac4bc58_netcg_sock [bpf] ffff80000879d6d8-ffff80000ad656b4: bpf_prog_76867454b5944e15_netcg_getsockopt [bpf] ffff80000ad656b4-ffffd69b7af74048: bpf_prog_1d50286d2eb1be85_hn_egress [bpf] <---------- here ffffd69b7af74048-ffffd69b7af74048: $x.5 [sha3_generic] ffffd69b7af74048-ffffd69b7af740b8: crypto_sha3_init [sha3_generic] ffffd69b7af740b8-ffffd69b7af741e0: crypto_sha3_update [sha3_generic] The logic in symbols__fixup_end() just uses curr->start to update the prev->end. But in this case, it won't work as it's too different. I think ARM has a different kernel memory layout for modules and BPF than on x86. Actually there's a logic to handle kernel and module boundary. Let's do the same for symbols between different modules.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
