Since moving the interface combination checks to mac80211, it's
broken because it now only considers interfaces with an assigned
channel context, so for example any interface that isn't active
can still be up, which is clearly an issue; also, in particular
P2P-Device wdevs are an issue since they never have a chanctx.
Fix this by counting running interfaces instead the ones with a
channel context assigned.

The HCI_CONN_REMOTE_OOB connection flag is used to indicate if the

When only the pairing initiator is providing out-of-band data, then
the receiver side was ignoring the data. For some reason the code was
checking if the initiator has received out-of-band data and only then
also provide the required inidication that the acceptor actually has
the needed data available.
For BR/EDR out-of-band pairing it is enough if one side has received
out-of-band data. There are no extra checks needed here to make this
work smoothly. The only thing that is needed is to tell the controller
if data is present (and if it is P-192 or P-256 or both) and then let
the controller actually figure out the rest.
This means the check for outgoing connection or if the initiator has
indicated data are completely pointless and are in fact actually
causing harm. The check in question is this one:
if (conn->out || test_bit(HCI_CONN_REMOTE_OOB, &conn->flags)) {
After just taking the conditional check out and always executing the
code for determining the type of out-of-band data, the pairing works
flawlessly and prodcudes authenticated link keys.
The patch itself looks more complicated due to the reformatting of the
indentation, but it essentially just a two-line change.

rhashtable: Fix two bugs caused by multiple rehash preparation
While testing some new patches over the weekend I discovered a
couple of bugs in the series that had just been merged. These
two patches fix them:
1) A use-after-free in the walker that can cause crashes when
walking during a rehash.
2) When a second rehash starts during a single rhashtable_remove
call the remove may fail when it shouldn't.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The commit 9d901bc051 ("rhashtable:
Free bucket tables asynchronously after rehash") causes gratuitous
failures in rhashtable_remove.
The reason is that it inadvertently introduced multiple rehashing
from the perspective of readers. IOW it is now possible to see
more than two tables during a single RCU critical section.
Fortunately the other reader rhashtable_lookup already deals with
this correctly thanks to c4db8848af
("rhashtable: rhashtable: Move future_tbl into struct bucket_table")
so only rhashtable_remove is broken by this change.
This patch fixes this by looping over every table from the first
one to the last or until we find the element that we were trying
to delete.
Incidentally the simple test for detecting rehashing to prevent
starting another shrinking no longer works. Since it isn't needed
anyway (the work queue and the mutex serves as a natural barrier
to unnecessary rehashes) I've simply killed the test.

This patch fixes it by moving the RCU read unlock down to the bottom

but it got dropped while rearranging patches because this one
depended on the async freeing of bucket_table.

====================
bpf: allow eBPF access skb fields
V1->V2:
- refactored field access converter into common helper convert_skb_access()
used in both classic and extended BPF
- added missing build_bug_on for field 'len'
- added comment to uapi/linux/bpf.h as suggested by Daniel
- dropped exposing 'ifindex' field for now
classic BPF has a way to access skb fields, whereas extended BPF didn't.
This patch introduces this ability.
Classic BPF can access fields via negative SKF_AD_OFF offset.
Positive bpf_ld_abs N is treated as load from packet, whereas
bpf_ld_abs -0x1000 + N is treated as skb fields access.
Many offsets were hard coded over years: SKF_AD_PROTOCOL, SKF_AD_PKTTYPE, etc.
The problem with this approach was that for every new field classic bpf
assembler had to be tweaked.
I've considered doing the same for extended, but for every new field LLVM
compiler would have to be modifed. Since it would need to add a new intrinsic.
It could be done with single intrinsic and magic offset or use of inline
assembler, but neither are clean from compiler backend point of view, since
they look like calls but shouldn't scratch caller-saved registers.
Another approach was to introduce a new helper functions like bpf_get_pkt_type()
for every field that we want to access, but that is equally ugly for kernel
and slow, since helpers are calls and they are slower then just loads.
In theory helper calls can be 'inlined' inside kernel into direct loads, but
since they were calls for user space, compiler would have to spill registers
around such calls anyway. Teaching compiler to treat such helpers differently
is even uglier.
They were few other ideas considered. At the end the best seems to be to
introduce a user accessible mirror of in-kernel sk_buff structure:
struct __sk_buff {
__u32 len;
__u32 pkt_type;
__u32 mark;
__u32 queue_mapping;
};
bpf programs will do:
int bpf_prog1(struct __sk_buff *skb)
{
__u32 var = skb->pkt_type;
which will be compiled to bpf assembler as:
dst_reg = *(u32 *)(src_reg + 4) // 4 == offsetof(struct __sk_buff, pkt_type)
bpf verifier will check validity of access and will convert it to:
dst_reg = *(u8 *)(src_reg + offsetof(struct sk_buff, __pkt_type_offset))
dst_reg &= 7
since 'pkt_type' is a bitfield.
No new instructions added. LLVM doesn't need to be modified.
JITs don't change and verifier already knows when it accesses 'ctx' pointer.
The only thing needed was to convert user visible offset within __sk_buff
to kernel internal offset within sk_buff.
For 'len' and other fields conversion is trivial.
Converting 'pkt_type' takes 2 or 3 instructions depending on endianness.
More fields can be exposed by adding to the end of the 'struct __sk_buff'.
Like vlan_tci and others can be added later.
When pkt_type field is moved around, goes into different structure, removed or
its size changes, the function convert_skb_access() would need to updated and
it will cover both classic and extended.
Patch 2 updates examples to demonstrates how fields are accessed and
adds new tests for verifier, since it needs to detect a corner case when
attacker is using single bpf instruction in two branches with different
register types.
The 4 fields of __sk_buff are already exposed to user space via classic bpf and
I believe they're useful in extended as well.

The linux kernel has supported the TiVo Slide remote control for some time, but
does not recognize the USB ID of the newer Slide Pro. This patch adds the
missing data structures so the newer remote will be recognized by the driver,
thereby allowing the TiVo, LiveTV, and Thumbs Up/Down buttons to be
mapped with a hwdb file.

The OOB data requires to include LE Bluetooth Device Address and LE Role

The eir_append_data helper function is needed for generating the

The flags for the management command table used manual encoding of
bits in the form of (1 << n). It is however preferred to use BIT(n)
macro instead.

Changes to the global configuration updates like settings, class of
device, name etc. can be received by every user. They are allowed to
read them in the first place so provide the updates via events as
well. Otherwise untrusted users start polling for updates and that
is not a desired behavior.

Until now the management interface was restricted to CAP_NET_ADMIN. With
this change every user can open the management socket. However the list
of commands is heavily restricted to getting basic information about the
attached controllers. No access for configuration or other operation is
provided. The events are also limited. This is done so that no keys can
leak or untrusted users can mess with the Bluetooth configuration.

Check the required trust level of each management command with the trust
level of the management socket. If it does not match up, then return the
newly introduced permission denied error.

The flags field for the management command table will be always
initialized to zero and thus no need to do that manually.
