When cls_bpf offload was added it seemed like a good idea to
call cls_bpf_delete_prog() instead of extending the error
handling path, since the software state is fully initialized
at that point. This handling of errors without jumping to
the end of the function is error prone, as proven by later
commit missing that extra call to __cls_bpf_delete_prog().
__cls_bpf_delete_prog() is now expected to be invoked with
a reference on exts->net or the field zeroed out. The call
on the offload's error patch does not fullfil this requirement,
leading to each error stealing a reference on net namespace.
Create a function undoing what cls_bpf_set_parms() did and
use it from __cls_bpf_delete_prog() and the error path.

block_offset * qi_dqperchunk == first id in that chunk,

Under some circumstances, an incremental send operation can issue wrong
paths for unlink commands related to files that have multiple hard links
and some (or all) of those links were renamed between the parent and send
snapshots. Consider the following example:
Parent snapshot
. (ino 256)
|---- a/ (ino 257)
| |---- b/ (ino 259)
| | |---- c/ (ino 260)
| | |---- f2 (ino 261)
| |
| |---- f2l1 (ino 261)
|
|---- d/ (ino 262)
|---- f1l1_2 (ino 258)
|---- f2l2 (ino 261)
|---- f1_2 (ino 258)
Send snapshot
. (ino 256)
|---- a/ (ino 257)
| |---- f2l1/ (ino 263)
| |---- b2/ (ino 259)
| |---- c/ (ino 260)
| | |---- d3 (ino 262)
| | |---- f1l1_2 (ino 258)
| | |---- f2l2_2 (ino 261)
| | |---- f1_2 (ino 258)
| |
| |---- f2 (ino 261)
| |---- f1l2 (ino 258)
|
|---- d (ino 261)
When computing the incremental send stream the following steps happen:
1) When processing inode 261, a rename operation is issued that renames
inode 262, which currently as a path of "d", to an orphan name of
"o262-7-0". This is done because in the send snapshot, inode 261 has
of its hard links with a path of "d" as well.
2) Two link operations are issued that create the new hard links for
inode 261, whose names are "d" and "f2l2_2", at paths "/" and
"o262-7-0/" respectively.
3) Still while processing inode 261, unlink operations are issued to
remove the old hard links of inode 261, with names "f2l1" and "f2l2",
at paths "a/" and "d/". However path "d/" does not correspond anymore
to the directory inode 262 but corresponds instead to a hard link of
inode 261 (link command issued in the previous step). This makes the
receiver fail with a ENOTDIR error when attempting the unlink
operation.
The problem happens because before sending the unlink operation, we failed
to detect that inode 262 was one of ancestors for inode 261 in the parent
snapshot, and therefore we didn't recompute the path for inode 262 before
issuing the unlink operation for the link named "f2l2" of inode 262. The
detection failed because the function "is_ancestor()" only follows the
first hard link it finds for an inode instead of all of its hard links
(as it was originally created for being used with directories only, for
which only one hard link exists). So fix this by making "is_ancestor()"
follow all hard links of the input inode.
A test case for fstests follows soon.

syzkaller found a race condition fanout_demux_rollover() while removing
a packet socket from a fanout group.
po->rollover is read and operated on during packet_rcv_fanout(), via
fanout_demux_rollover(), but the pointer is currently cleared before the
synchronization in packet_release(). It is safer to delay the cleanup
until after synchronize_net() has been called, ensuring all calls to
packet_rcv_fanout() for this socket have finished.
To further simplify synchronization around the rollover structure, set
po->rollover in fanout_add() only if there are no errors. This removes
the need for rcu in the struct and in the call to
packet_getsockopt(..., PACKET_ROLLOVER_STATS, ...).

Error code returned by 'bnxt_read_sfp_module_eeprom_info()' is handled a
few lines above when reading the A0 portion of the EEPROM.
The same should be done when reading the A2 portion of the EEPROM.
In order to correctly propagate an error, update 'rc' in this 2nd call as
well, otherwise 0 (success) is returned.

The Marvell 10G PHY driver supports different hardware revisions, which
have their bits 3..0 differing. To get the correct revision number these
bits should be ignored. This patch fixes this by using the already
defined MARVELL_PHY_ID_MASK (0xfffffff0) instead of the custom
0xffffffff mask.
Fixes: 20b2af32ff ("net: phy: add Marvell Alaska X 88X3310 10Gigabit PHY support")

This patch fixes the Tx ring size checks when using ethtool, by adding
an extra check in the PPv2 check_ringparam_valid helper. The Tx ring
size cannot be set to a value smaller than the minimum number of
descriptors needed for TSO.
Fixes: 1d17db08c0 ("net: mvpp2: limit TSO segments and use stop/wake thresholds")

Short fragmented packets may never be sent by the hardware when padding
is disabled. This patch stop modifying the GMAC padding bits, to leave
them to their reset value (disabled).
Fixes: 3919357fb0 ("net: mvpp2: initialize the GMAC when using a port")
