commit 9b88f9fb0d2fc8f7e71e75a42c5a064bc6cfffd2
category: bugfix
bugzilla: 25031
CVE: NA
---------------------------

When ext4_mkdir(), ext4_symlink(), ext4_create(), or ext4_mknod() fail
to add entry into directory, it ends up dropping freshly created inode
under the running transaction and thus inode truncation happens under
that transaction. That breaks assumptions that evict() does not get
called from a transaction context and at least in ext4_symlink() case it
can result in inode eviction deadlocking in inode_wait_for_writeback()
when flush worker finds symlink inode, starts to write it back and
blocks on starting a transaction. So change the code in ext4_mkdir() and
ext4_add_nondir() to drop inode reference only after the transaction is
stopped. We also have to add inode to the orphan list in that case as
otherwise the inode would get leaked in case we crash before inode
deletion is committed.

Use sgl API to get sgl dma addr and len, this will help to avoid compile

can only be selected by arch code.
2. Fix issue with wrong number of sg elements after dma map
We fill the hardware scatter gather list assuming it will need the same
number of elements at the original scatterlist. If an IOMMU is involved,
then it may well need fewer. The return value of dma_map_sg tells us how
many.
Probably never caused visible problems as the hardware won't get to
the elements that are incorrect before it finds enough space.

Currently, Port base vlan is initiated by PF and configured to its VFs,
by using command "ip link set <pf name> vf <vf id> vlan <vlan id>".
When a global reset was triggered, the hardware vlan table and the soft
recorded vlan information will be cleared by PF, and restored them until
VFs were ready. There is a short time window between the table had been
cleared and before table restored. If configured a new port base vlan tag
at this moment, driver will check the soft recorded vlan information,
and find there hasn't the old tag in it, which causing a warning print.

Due to the port base vlan is managed by PF, so the VFs's port base vlan
restoring should be handled by PF when PF was ready.

For some boards the fibre port supports autoneg, and the firmware
handles the autoneg speed and user speed separately.

step 1: user disables autoneg, and set the mac speed A, the driver
will update the mac speed to A.
step 2: user enables autoneg, and the negotiated speed is B, the
driver will update the mac speed to B.
step 3: user disable the autoneg, and set the mac speed B, the
driver will discard the set mac speed B command, because the speed
is not changed by step 2. But for firmware, it will change the mac
speed to A by step 1 when received disable autoneg command.
In this case, the port can't link up.

This patch fixes it by skip mac speed and duplex modification
checking for fibre port support autoneg.
