commit 8d48562a2729742f767b0fdd994d6b2a56a49c63 upstream.
The recent change to get_phb_number() causes a DEBUG_ATOMIC_SLEEP
warning on some systems:

This is because pcibios_alloc_controller() holds hose_spinlock but
of_alias_get_id() takes of_mutex which can sleep.
The hose_spinlock protects the phb_bitmap, and also the hose_list, but
it doesn't need to be held while get_phb_number() calls the OF routines,
because those are only looking up information in the device tree.
So fix it by having get_phb_number() take the hose_spinlock itself, only
where required, and then dropping the lock before returning.
pcibios_alloc_controller() then needs to take the lock again before the
list_add() but that's safe, the order of the list is not important.

commit 976bf59c69cd2e2c17f0ab20a14c0e700cba0f15 upstream.
This uses a pseudo-linearization scheme with a 64k global buffer,
but BIG TCP arrival means IPv6 TCP stack can generate skbs
that exceed this size.
In practice, IRC commands are not expected to exceed 512 bytes, plus
this is interactive protocol, so we should not see large packets
in practice.
Given most IRC connections nowadays use TLS so this helper could also be
removed in the near future.

This uses a pseudo-linearization scheme with a 64k global buffer,
but BIG TCP arrival means IPv6 TCP stack can generate skbs
that exceed this size.
Use skb_linearize. It should be possible to rewrite this to properly
deal with segmented skbs (i.e., only do small chunk-wise accesses),
but this is going to be a lot more intrusive than this because every
helper function needs to get the sk_buff instead of a pointer to a raw
data buffer.
In practice, provided we're really looking at FTP control channel packets,
there should never be a case where we deal with huge packets.

With BIG TCP, packets generated by tcp stack may exceed 64kb.
Cap datalen at 64kb. The internal message format uses 16bit fields,
so no embedded message can exceed 64k size.
Multiple h323 messages in a single superpacket may now result
in a message to get treated as incomplete/truncated, but thats
better than scribbling past h323_buffer.
Another alternative suitable for net tree would be a switch to
skb_linearize().

commit 0b2f3212b551a87fe936701fa0813032861a3308 upstream.
To avoid allocation of the conntrack extension area when possible,
the default behaviour was changed to only allocate the event extension
if a userspace program is subscribed to a notification group.
Problem is that while 'conntrack -E' does enable the event allocation
behind the scenes, 'conntrack -E expect' does not: no expectation events
are delivered unless user sets
"net.netfilter.nf_conntrack_events" back to 1 (always on).
Fix the autodetection to also consider EXP type group.
We need to track the 6 event groups (3+3, new/update/destroy for events and
for expectations each) independently, else we'd disable events again
if an expectation group becomes empty while there is still an active
event group.

commit d6d142cb7f79bec6051c5ecf744b7a5309c5a0ee upstream.
The iSER Initiator uses two types of receive buffers:
- one big login buffer posted by iser_post_recvl();
- several small message buffers posted by iser_post_recvm().
The login buffer is used at the login phase and full feature phase in
the discovery session. It may take a few requests and responses to
complete the login phase. The message buffers are only used in the
normal operational session at the full feature phase.
After the commit referred in the fixes line, the login operation fails
if the authentication is enabled. That happens because the Initiator
posts a small receive buffer after the first response from Target. So,
the next send operation fails because Target's second response does not
fit into the small receive buffer.
This commit adds additional checks to prevent posting small receive
buffers until the full feature phase.

commit 754590651ccbbcc74a7c20907be4bb15d642bde3 upstream.
When DPCM tries to add valid BE connections at dpcm_add_paths(), it
doesn't check whether the picked BE actually supports for the given
stream direction. Due to that, when an asymmetric BE stream is
present, it picks up wrongly and this may result in a NULL dereference
at a later point where the code assumes the existence of a
corresponding BE substream.
This patch adds the check for the presence of the substream for the
target BE for avoiding the problem above.
Note that we have already some fix for non-existing BE substream at
commit 6246f283d5e0 ("ASoC: dpcm: skip missing substream while
applying symmetry"). But the code path we've hit recently is rather
happening before the previous fix. So this patch tries to fix at
picking up a BE instead of parsing BE lists.

commit 419831617ed349992c84344dbd9e627f9e68f842 upstream.
iavf_alloc_asq_bufs/iavf_alloc_arq_bufs allocates with dma_alloc_coherent
memory for VF mailbox.
Free DMA regions for both ASQ and ARQ in case error happens during
configuration of ASQ/ARQ registers.
Without this change it is possible to see when unloading interface:

commit fd0c153daad135d0ec1a53c5dbe6936a724d6ae1 upstream.
If we use the ancient SysV syscall ABI, we'd better have tell the
kernel how to claim that a negative return value is a success.
Use ->orig_r2 for that - it's inaccessible via ptrace, so it's
a fair game for changes and it's normally[*] non-negative on return
from syscall. Set to -1; syscall is not going to be restart-worthy
by definition, so we won't interfere with that use either.
[*] the only exception is rt_sigreturn(), where we skip the entire
messing with r1/r2 anyway.

512 in r2 and 1 in r1.

In this case a bounce buffer is returned by i2c_get_dma_safe_msg_buf(),
and it has to synced back to the message after the transfer is done.
Add missing assignment of dma buffer in geni_i2c_gpi().
Set xferred in i2c_put_dma_safe_msg_buf() to true in case of no error to
ensure the sync-back of this dma buffer to the message.
