BPF Compiler Collection (BCC)
|
||||
|
||||
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. Much of
|
||||
what BCC uses requires Linux 4.1 and above.
|
||||
|
||||
eBPF was described by Ingo Molnár as:
|
||||
|
||||
One of the more interesting features in this cycle is the ability to
|
||||
attach eBPF programs (user-defined, sandboxed bytecode executed by the
|
||||
kernel) to kprobes. This allows user-defined instrumentation on a live
|
||||
kernel image that can never crash, hang or interfere with the kernel
|
||||
negatively.
|
||||
|
||||
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.

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
