Hi,
I am measuring the time cost of parallel creation and destruction of
net namespaces.
As cleanup_net() is invoked from workqueue, the exit of a net
namespace does not mean the cleanup is completed. Therefore I use
ftrace to count the number of net_drop_ns() are called. But I found
that the num

Add a small skb_mac_header_len() helper similarly as the
skb_network_header_len() we have and replace open coded
places in BPF's bpf_skb_change_proto() helper. Will also
be used in upcoming work.

This work tries to make the semantics and code around the
narrower ctx access a bit easier to follow. Right now
everything is done inside the .is_valid_access(). Offset
matching is done differently for read/write types, meaning
writes don't support narrower access and thus matching only
on offsetof

Currently, bpf_trace_printk does not support common formatting
symbol '%i' however vsprintf does and is what eventually gets
called by bpf helper. If users are used to '%i' and currently
make use of it, then bpf_trace_printk will just return with
error without dumping anythin
We do export through fdinfo already whether a prog is JITed or not,
given a program load can fail in case of either prog or tail call map

This work adds a helper that can be used to adjust net room of an
skb. The helper is generic and can be further extended in future.
Main use case is for having a programmatic way to add/remove room to
v4/v6 header options along with cls_bpf on egress and ingress hook
of the data path. It reuses mos

Currently the verifier does not track imm across alu operations when
the source register is of unknown type. This adds additional pattern
matching to catch this and track imm. We've seen LLVM generating this
pattern while working on cilium.

Miscellanous improvements I still had in my queue, it adds a new
bpf_skb_adjust_room() helper for cls_bpf, exports to fdinfo whether
tail call array owner is JITed, so iproute2 error reporting can be
improved on that regard, a small cleanup and extension to trace

Hi Dave,
Here are some more Bluetooth patches for the 4.13 kernel:

- Added sockaddr length checks before accessing sa_family
- Fixed possible "might sleep" errors in bnep, cmtp and hidp modules
- A few other minor fixes
