From c17a12ac030c5d9c812e611f8132570af0e795af Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] Fix bpf_pseudo_fd() type conversion error
With llvm15 and llvm16, the following command line
sudo ./trace.py 'smp_call_function_single "%K", arg1'
will cause error:
/virtual/main.c:60:36: error: incompatible integer to pointer conversion passing 'u64'
(aka 'unsigned long long') to parameter of type 'void *' [-Wint-conversion]
bpf_perf_event_output(ctx, bpf_pseudo_fd(1, -1), CUR_CPU_IDENTIFIER, &__data, sizeof(__data));
^~~~~~~~~~~~~~~~~~~~
1 error generated.
Failed to compile BPF module <text>
In helpers.h, we have
u64 bpf_pseudo_fd(u64, u64) asm("llvm.bpf.pseudo");
Apparently, <= llvm14 can tolerate u64 -> 'void *' conversion, but
llvm15 by default will cause an error.
Let us explicitly convert bpf_pseudo_fd to 'void *' to avoid
such errors.

Subject: [PATCH 2/2] Fix clang 15 int to pointer conversion errors
Since version 15, clang issues error for implicit conversion of
integer to pointer. Several tools are broken. This patch add explicit
pointer cast where needed.
Fixes the following errors:

Subject: [PATCH] Fix some documentation issues (#4197)
* compactsnoop-manpage: fix the name of the tool in the NAME section
In its manpage, compactsnoop tools is called compacstall in the NAME
section. I don't know where that name comes from, but it should be
compactsnoop.
* dirtop-manpage: use '-d' option in the EXAMPLES section
The mandatory '-d' option of dirtop is missing in the EXAMPLES
section. Copy it from the usage message. Also remove '.py' suffixes.
* funclatency-manpage: fix typo in one of the examples
There is a spurious colon in one of the manpage examples. Remove it.
* tools/killsnoop: add '-s' option in the synopsis of the example file
Commit 33c8b1ac ("Update man page and example file") added '-s' option
to the manpage and an example in the example file, but missed the
sysnopsis in that later case.
* trace-manpage: add missing options (-c,-n,-f and -B) to the synopsis
Copy the full sysopsis from the usage message.
* tcptracer-manpage: add missing '-t' option in the manpage
Add '-t' option to the synopsis and description.
* tcpsubnet-manpage: remove '--ebpf' option from the manpage
This option is explicitly suppressed in argparse and no manpage of
other tools mentions it.
* manpages: remove '.py' suffix from the synopsis of some *snoop tools
Other manpages don't show the suffix, nor do the usage messages.

Subject: [PATCH] bcc: support building with external libbpf package and older
uapi linux/bpf.h
When building bcc with a relatively new packaged libbpf (0.8.1)
and -DCMAKE_USE_LIBBPF_PACKAGE:BOOL=TRUE, multiple compilation
failures are encountered due the fact the system uapi header
in /usr/include/linux/bpf.h is not very recent (this is often
the case for distros, which sync it via a kernel headers
package quite conservatively due to use by glibc).
With libbpf built via git submodule, the uapi header included in
the libbpf package is used, so here a similar approach is proposed
for the external package build. Instead of having to sync
another file the already present compat/linux/virtual_bpf.h
is used; we copy it to compat/linux/bpf.h (eliminating the
string prefix/suffix on first/last lines).
From there, we ensure that places that assume the presence of
the libbpf git submodule point at compat/ as a location to
find the uapi header.

%description
BCC is a toolkit for creating efficient kernel tracing and manipulation
programs, and includes several useful tools and examples. It makes use of
extended BPF (Berkeley Packet Filters), formally known as eBPF, a new feature
that was first added to Linux 3.15. BCC makes BPF programs easier to write,
with kernel instrumentation in C (and includes a C wrapper around LLVM), and
front-ends in Python and lua. It is suited for many tasks, including
performance analysis and network traffic control.
