If the bond is enslaving a device with different type it will be setup
by it, but if after being setup the enslave fails the bond doesn't
switch back its type and also keeps pointers to foreign structures that can
be long gone. Thus revert back any type changes if the enslave failed and
the bond had to change its type.
Example:
 Before patch:
$ echo lo > bond0/bonding/slaves
-bash: echo: write error: Cannot assign requested address
$ ip l sh bond0
20: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN
mode DEFAULT group default
    link/loopback 16:54:78:34:bd:41 brd 00:00:00:00:00:00
$ echo +eth1 > bond0/bonding/slaves
$ ip l sh bond0
20: bond0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
    link/ether 52:54:00:3f:47:69 brd ff:ff:ff:ff:ff:ff
(notice the MASTER flag is gone)

 After patch:
$ echo lo > bond0/bonding/slaves
-bash: echo: write error: Cannot assign requested address
$ ip l sh bond0
21: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN

When the bonding is being unloaded and the netdevice notifier is
unregistered it executes NETDEV_UNREGISTER for each device which should
remove the bond's proc entry but if the device enslaved is not of
ARPHRD_ETHER type and is in front of the bonding, it may execute
bond_release_and_destroy() first which would release the last slave and
destroy the bond device leaving the proc entry and thus we will get the

Thus remove the proc entry manually if bond_release_and_destroy() is
used. Because of the checks in bond_remove_proc_entry() it's not a
problem for a bond device to change namespaces (the bug fixed by the

f9399814 ("bonding: Don't allow bond devices to change network

The mv88e6xxx_priv_state structure contains an fid_mask, where 1 means
the FID is free to use, 0 means the FID is in use.

This patch fixes the bit clear in mv88e6xxx_leave_bridge() when
assigning a new FID to a port.

Example scenario: I have 7 ports, port 5 is CPU, port 6 is unused (no
PHY). After setting the ports 0, 1 and 2 in bridge br0, and ports 3 and
4 in bridge br1, I have the following fid_mask: 0b111110010110 (0xf96).

Indeed, br0 uses FID 0, and br1 uses FID 3.

After setting nomaster for port 0, I get the wrong fid_mask: 0b10 (0x2).

With this patch we correctly get 0b111110010100 (0xf94), meaning port 0
uses FID 1, br0 uses FID 0, and br1 uses FID 3.

Commit 79901317 ("n_tty: Don't flush buffer when closing ldisc"),
first merged in kernel release 3.10, caused the following regression
in the Gigaset M101 driver:

Before that commit, when closing the N_TTY line discipline in
preparation to switching to N_GIGASET_M101, receive_room would be
reset to a non-zero value by the call to n_tty_flush_buffer() in
n_tty's close method. With the removal of that call, receive_room
might be left at zero, blocking data reception on the serial line.

The present patch fixes that regression by setting receive_room
to an appropriate value in the ldisc open method.

Currently F-RTO may repeatedly send new data packets on non-recurring
timeouts in CA_Loss mode. This is a bug because F-RTO (RFC5682)
should only be used on either new recovery or recurring timeouts.

This exacerbates the recovery progress during frequent timeout &
repair, because we prioritize sending new data packets instead of
repairing the holes when the bandwidth is already scarce.

When we calculate the checksum on the recv path, we store the
result in the skb as an optimisation in case we need the checksum
again down the line.

This is in fact bogus for the MSG_PEEK case as this is done without
any locking.  So multiple threads can peek and then store the result
to the same skb, potentially resulting in bogus skb states.

This patch fixes this by only storing the result if the skb is not
shared.  This preserves the optimisations for the few cases where
it can be done safely due to locking or other reasons, e.g., SIOCINQ.

Shared skbs must not be modified and this is crucial for broadcast
and/or multicast paths where we use it as an optimisation to avoid
unnecessary cloning.

The function skb_recv_datagram breaks this rule by setting peeked
without cloning the skb first.  This causes funky races which leads
to double-free.

This patch fixes this by cloning the skb and replacing the skb
in the list when setting skb->peeked.

Similarly as in commit 4f7d2cdf ("rtnetlink: verify IFLA_VF_INFO
attributes before passing them to driver"), we have a double nesting
of netlink attributes, i.e. IFLA_VF_PORTS only contains IFLA_VF_PORT
that is nested itself. While IFLA_VF_PORTS is a verified attribute
from ifla_policy[], we only check if the IFLA_VF_PORTS container has
IFLA_VF_PORT attributes and then pass the attribute's content itself
via nla_parse_nested(). It would be more correct to reject inner types
other than IFLA_VF_PORT instead of continuing parsing and also similarly
as in commit 4f7d2cdf, to check for a minimum of NLA_HDRLEN.
