Recently salvaged this 'BCM43142A0' WiFi/Bluetooth module from a Lenovo laptop
and noticed it doesn't work automatically, because the USB IDs are missing
from btusb.c.
Plugging in the adapter on Linux 4.1 (dmesg):

Support for the chipset was added in commit 88f9b65 and a similar BCM43142
based device was added in commit 8f0c304.
To work around the issue, I got the firmware
(BCM43142A0_001.001.011.0122.0153) off a Windows installation of Broadcom
bluetooth driver and converted it to a .hcd -file via. hex2hcd and placed it
in /lib/firmware/brcm/BCM.hcd. After that:
$ echo "105b e065 0 19ff 0239" > /sys/bus/usb/drivers/btusb/new_id

The HIDP specs define an idle-timeout which automatically disconnects a
device. This has always been implemented in the HIDP layer and forced a
synchronous shutdown of the hidp-scheduler. This works just fine, but
lacks a forced disconnect on the underlying l2cap channels. This has been
broken since:
commit 5205185d461d5902325e457ca80bd421127b7308
Author: David Herrmann <dh.herrmann@gmail.com>
Date: Sat Apr 6 20:28:47 2013 +0200
Bluetooth: hidp: remove old session-management
The old session-management always forced an l2cap error on the ctrl/intr
channels when shutting down. The new session-management skips this, as we
don't want to enforce channel policy on the caller. In other words, if
user-space removes an HIDP device, the underlying channels (which are
*owned* and *referenced* by user-space) are still left active. User-space
needs to call shutdown(2) or close(2) to release them.
Unfortunately, this does not work with idle-timeouts. There is no way to
signal user-space that the HIDP layer has been stopped. The API simply
does not support any event-passing except for poll(2). Hence, we restore
old behavior and force EUNATCH on the sockets if the HIDP layer is
disconnected due to idle-timeouts (behavior of explicit disconnects
remains unmodified). User-space can still call
getsockopt(..., SO_ERROR, ...)
..to retrieve the EUNATCH error and clear sk_err. Hence, the channels can
still be re-used (which nobody does so far, though). Therefore, the API
still supports the new behavior, but with this patch it's also compatible
to the old implicit channel shutdown.

The change to bpa10x to use the h4_recv_buf helper added a dependency
on BT_HCIUART. This was incorrectly added to Kconfig by adding a
'select' statement, which now in turn causes build failures
when CONFIG_TTY is not set:
warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct dependencies (NET && BT && TTY)
vers/built-in.o: In function `hci_uart_tty_receive':
fpga-mgr.c:(.text+0x282824): undefined reference to `tty_unthrottle'
drivers/built-in.o: In function `hci_uart_tty_ioctl':
fpga-mgr.c:(.text+0x282aa0): undefined reference to `n_tty_ioctl_helper'
drivers/built-in.o: In function `hci_uart_flush':
This replaces the 'select BT_HCIUART' dependency with 'depends on', which
does not have this kind of problem. Alternatively, one could add 'depends
on TTY', but avoiding 'select' on user-visible options is generally the
preferred choice as that does not introduce the potential for dependency
loops or incomplete dependency chains.

There are LE devices on the market that start off by announcing their
public address and then once paired switch to using private address.
To be interoperable with such devices we should simply trust the fact
that we're receiving an IRK from them to indicate that they may use
private addresses in the future. Instead, simply tie the persistency
to the bonding/no-bonding information the same way as for LTKs and
CSRKs.

Link interrupts are enabled in init_umac(), which is too early for us to
process them since we do not yet have a valid PHY device pointer. On
BCM7425 chips for instance, we will crash calling phy_mac_interrupt()
because phydev is NULL.
Fix this by moving the link interrupts enabling in
bcmgenet_netif_start(), under a specific function:
bcmgenet_link_intr_enable() and while at it, update the comments
surrounding the code.

Sowmini found hang with rds-ping while testing RDS over TCP. Its

This happens because rds_send_xmit() chain wants to take
sock_lock which is already taken by tcp_v4_rcv() on its
way to rds_tcp_data_ready(). Commit db6526dcb51b ("RDS: use
rds_send_xmit() state instead of RDS_LL_SEND_FULL") which
was trying to opportunistically finish the send request
in same thread context.
But because of above recursive lock hang with RDS TCP,
the send work from rds_send_pong() needs to deferred to
worker to avoid lock up. Given RDS ping is more of connectivity
test than performance critical path, its should be ok even
for transport like IB.

Before lightweight tunnels existed, it really didn't make sense to
create a tunnel that was not fully specified, such as without a
destination IP address - the resulting packets would go nowhere.
However, with lightweight tunnels, the opposite is true - it doesn't
make sense to require this information when it will be provided later
on by the route. This loosens the requirements for this information.
An alternative would be to allow the relaxed version only when
COLLECT_METADATA is enabled. However, since there are several
variations on this theme (such as NBMA tunnels in GRE), just dropping
the restrictions seems the most consistent across tunnels and with
the existing configuration.

At the time of commit fff326990789 ("tcp: reflect SYN queue_mapping into
SYNACK packets") we had little ways to cope with SYN floods.
We no longer need to reflect incoming skb queue mappings, and instead
can pick a TX queue based on cpu cooking the SYNACK, with normal XPS
affinities.
Note that all SYNACK retransmits were picking TX queue 0, this no longer
is a win given that SYNACK rtx are now distributed on all cpus.

If OVS receives a packet from another namespace, then the packet should
be scrubbed. However, people have already begun to rely on the behaviour
that skb->mark is preserved across namespaces, so retain this one field.
This is mainly to address information leakage between namespaces when
using OVS internal ports, but by placing it in ovs_vport_receive() it is
more generally applicable, meaning it should not be overlooked if other
port types are allowed to be moved into namespaces in future.

BITS_RX_EN is an 'unsigned long' constant, so the ones complement of that
has bits set that do not fit into a 32-bit variable on 64-bit architectures,

this patch fixes the bug triggered timeout sequence. when the connective

pause frame to the Soc's mac. At that time, the driver resets the relevant

netlink_dump() allocates skb based on the calculated min_dump_alloc or
a per socket max_recvmsg_len.
min_alloc_size is maximum space required for any single netdev
attributes as calculated by rtnl_calcit().
max_recvmsg_len tracks the user provided buffer to netlink_recvmsg.
It is capped at 16KiB.
The intention is to avoid small allocations and to minimize the number
of calls required to obtain dump information for all net devices.
netlink_dump packs as many small messages as could fit within an skb
that was sized for the largest single netdev information. The actual
space available within an skb is larger than what is requested. It could
be much larger and up to near 2x with align to next power of 2 approach.
Allowing netlink_dump to use all the space available within the
allocated skb increases the buffer size a user has to provide to avoid
truncaion (i.e. MSG_TRUNG flag set).
It was observed that with many VLANs configured on at least one netdev,
a larger buffer of near 64KiB was necessary to avoid "Message truncated"
error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when
min_alloc_size was only little over 32KiB.
This patch trims skb to allocated size in order to allow the user to
avoid truncation with more reasonable buffer size.

A dhcp server may provide parameters to a client from a pool of IP
addresses and using a shared rootfs, or provide a specific set of
parameters for a specific client, usually using the MAC address to
identify each client individually. The dhcp protocol also specifies
a client-id field which can be used to determine the correct
parameters to supply when no MAC address is available. There is
currently no way to tell the kernel to supply a specific client-id,
only the userspace dhcp clients support this feature, but this can
not be used when the network is needed before userspace is available
such as when the root filesystem is on NFS.
This patch is to be able to do something like "ip=dhcp,client_id_type,
client_id_value", as a kernel parameter to enable the kernel to
identify itself to the server.

ACPI SSCN/FMCN methods were originally added because then the platform can
provide the most accurate HCNT/LCNT values to the driver. However, this
seems not to be true for Dell Inspiron 7348 where using these causes the
touchpad to fail in boot:
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: controller timed out
The values received from ACPI are (in fast mode):
HCNT: 72
LCNT: 160
this translates to following timings (input clock is 100MHz on Broadwell):
tHIGH: 720 ns (spec min 600 ns)
tLOW: 1600 ns (spec min 1300 ns)
Bus period: 2920 ns (assuming 300 ns tf and tr)
Bus speed: 342.5 kHz
Both tHIGH and tLOW are within the I2C specification.
The calculated values when ACPI parameters are not used are (in fast mode):
HCNT: 87
LCNT: 159
which translates to:
tHIGH: 870 ns (spec min 600 ns)
tLOW: 1590 ns (spec min 1300 ns)
Bus period 3060 ns (assuming 300 ns tf and tr)
Bus speed 326.8 kHz
These values are also within the I2C specification.
Since both ACPI and calculated values meet the I2C specification timing
requirements it is hard to say why the touchpad does not function properly
with the ACPI values except that the bus speed is higher in this case (but
still well below the max 400kHz).
Solve this by adding DMI quirk to the driver that disables using ACPI
parameters on this particulare machine.

Greg reported crashes hitting the following check in __sk_backlog_rcv()
BUG_ON(!sock_flag(sk, SOCK_MEMALLOC));
The pfmemalloc bit is currently checked in sk_filter().
This works correctly for TCP, because sk_filter() is ran in
tcp_v[46]_rcv() before hitting the prequeue or backlog checks.
For UDP or other protocols, this does not work, because the sk_filter()
is ran from sock_queue_rcv_skb(), which might be called _after_ backlog
queuing if socket is owned by user by the time packet is processed by
softirq handler.

here:
https://lkml.org/lkml/2015/9/25/602 (Subject: "Re: [PATCH] dax: fix deadlock in __dax_fault").

builddeb script hasn't cleared debian/files between builds.
As debian/files keeps accumulating entries, the changes file will end up
growing indefinelty. With outdated entries in debian/files, builddeb
script will exit with failure. This regression impacts those who use
"make deb-pkg" target to build kernel into a .deb package and never use
"make mrproper" or other means to clean kernel tree from generated
directories.
To fix the regression, remove debian/files before starting build and in

Commit 6afdb859b710 ("mm: do not ignore mapping_gfp_mask in page cache
allocation paths") has caught some users of hardcoded GFP_KERNEL used in
the page cache allocation paths. This, however, wasn't complete and
there were others which went unnoticed.
Dave Chinner has reported the following deadlock for xfs on loop device:
: With the recent merge of the loop device changes, I'm now seeing
: XFS deadlock on my single CPU, 1GB RAM VM running xfs/073.
:
: The deadlocked is as follows:
:
: kloopd1: loop_queue_read_work
: xfs_file_iter_read
: lock XFS inode XFS_IOLOCK_SHARED (on image file)
: page cache read (GFP_KERNEL)
: radix tree alloc
: memory reclaim
: reclaim XFS inodes
: log force to unpin inodes
: <wait for log IO completion>
:
: xfs-cil/loop1: <does log force IO work>
: xlog_cil_push
: xlog_write
: <loop issuing log writes>
: xlog_state_get_iclog_space()
: <blocks due to all log buffers under write io>
: <waits for IO completion>
:
: kloopd1: loop_queue_write_work
: xfs_file_write_iter
: lock XFS inode XFS_IOLOCK_EXCL (on image file)
: <wait for inode to be unlocked>
:
: i.e. the kloopd, with it's split read and write work queues, has
: introduced a dependency through memory reclaim. i.e. that writes
: need to be able to progress for reads make progress.
:
: The problem, fundamentally, is that mpage_readpages() does a
: GFP_KERNEL allocation, rather than paying attention to the inode's
: mapping gfp mask, which is set to GFP_NOFS.
:
: The didn't used to happen, because the loop device used to issue
: reads through the splice path and that does:
:
: error = add_to_page_cache_lru(page, mapping, index,
: GFP_KERNEL & mapping_gfp_mask(mapping));
This has changed by commit aa4d86163e4 ("block: loop: switch to VFS
ITER_BVEC").
This patch changes mpage_readpage{s} to follow gfp mask set for the
mapping. There are, however, other places which are doing basically the
same.
lustre:ll_dir_filler is doing GFP_KERNEL from the function which
apparently uses GFP_NOFS for other allocations so let's make this
consistent.
cifs:readpages_get_pages is called from cifs_readpages and
__cifs_readpages_from_fscache called from the same path obeys mapping
gfp.
ramfs_nommu_expand_for_mapping is hardcoding GFP_KERNEL as well
regardless it uses mapping_gfp_mask for the page allocation.
ext4_mpage_readpages is the called from the page cache allocation path
same as read_pages and read_cache_pages
As I've noticed in my previous post I cannot say I would be happy about
sprinkling mapping_gfp_mask all over the place and it sounds like we
should drop gfp_mask argument altogether and use it internally in
__add_to_page_cache_locked that would require all the filesystems to use
mapping gfp consistently which I am not sure is the case here. From a
quick glance it seems that some file system use it all the time while
others are selective.
