Now it also captures gnutls_record_send and gnutls_record_recv calls. Added options to filter by pid or command name, or just one lib.

Based on the bug report in https://bugs.gentoo.org/show_bug.cgi?id=582770, mixing static+non-static libstdc++ can lead to crashes. Disable such combinations. Choosing to leave out the llvm check, since in practice clang is less likely to be provided statically, so the check should cover both cases.

Update readme with dns name and https for repo server

We enabled dns for the repo and builtbot, and then turned on letsencrypt for those as well. Yay, now we look slightly more official. Signed-off-by: Brenden Blanco <bblanco@plumgrid.com>

* add open_perf_event api for reading perf counters Though the rewriter table method existed, we were not yet opening up the perf counter in the proper way for it to be read. Introduce a c function to enable attaching perf counters to cpu-indexed table slots. The python side opens, assigns, then immediately closes the fd. Only the kernel keeps a reference, so closing the table or deleting the entry will be sufficient to free up the fd when finished. Signed-off-by: Brenden Blanco <bblanco@plumgrid.com> * Skip perf array hw counter test if unsupported Hardware counters are not available in all places (some VM environments), so gracefully skip on the particular error condition.

Recent USDT change removed `procstat.py`, which the `argdist` and `trace` tools are still referencing. This diff moves the only method (`which`) they are using into the `BPF` class. Also, make `BPF.find_library` not to call `decode()` on `None`.

Added a field `demangle_name` in the `bcc_symbol` struct. Calculate its value whenever possible. For C++ programs, this would make outputted stack traces look nicer. Example: http://pastebin.com/LqT0nP67

The current logic was only initializing page accesses, mark dirty.. at the beginning of the method, preventing counters to be ever reset for each PIDs. Piggyback https://github.com/iovisor/bcc/pull/615#discussion_r71056842 Tested by running both tools manually.

Added XDP support to BCC
-
Jan Rüth authored
Concretely, it adds two functions to bcc, namely: `attach_xdp` and `remove_xdp` which allows to attach an XDP program to a device (given via its name, e.g., en0) (in the future this might change to a specific queue on a device once the kernel offers this interface) and `remove_xdp` removes a XDP program from a device. Please note that there can currently be only one program attached to the device and attaching another program replaces the previous. One example is available to test XDP, in networking/xdp which drops all packets an counts for which protocol a packet was dropped (this is taken from the kernel xdp1 example). Please note that you cannot use the network headers defined in <bcc/proto.h> as they cause llvm/clang to generate instructions not available on XDP layer. On XDP layer you do not have an skb yet, so you are operating on the bare packet data. XDP support is currently limited to only some network adapters, there is the `mlx4` and there is also a patch available for the `e1000` driver.
