commit e538409257d0217a9bc715686100a5328db75a15 upstream.
Commit 65c79230576 tried to clear the custom firmware path on exit by
writing a single space to the firmware_class.path parameter. This
doesn't work because nothing strips this space from the value stored
and fw_get_filesystem_firmware() only ignores zero-length paths.
Instead, write a null byte.

Before the change, if the user passed a static rate value different
than zero and the FW doesn't support static rate,
it would end up configuring rate of 2.5 GBps.
Fix this by using rate 0; unlimited, in cases where FW
doesn't support static rate configuration.

The RDMA CM will select a source device and address by consulting
the routing table if no source address is passed into
rdma_resolve_address(). Userspace will ask for this by passing an
all-zero source address in the RESOLVE_IP command. Unfortunately
the new check for non-zero address size rejects this with EINVAL,
which breaks valid userspace applications.
Fix this by explicitly allowing a zero address family for the source.

commit 7d83fb14258b9961920cd86f0b921caaeb3ebe85 upstream.
During the "insert range" fallocate operation, i_size grows by the
specified 'len' bytes. XFS verifies that i_size + len < s_maxbytes, as
it should. But this comparison is done using the signed 'loff_t', and
'i_size + len' can wrap around to a negative value, causing the check to
incorrectly pass, resulting in an inode with "negative" i_size. This is
possible on 64-bit platforms, where XFS sets s_maxbytes = LLONG_MAX.
ext4 and f2fs don't run into this because they set a smaller s_maxbytes.
Fix it by using subtraction instead.
Reproducer:
xfs_io -f file -c "truncate $(((1<<63)-1))" -c "finsert 0 4096"

commit 8f22e52528cc372b218b5f100457469615c733ce upstream.
The sequencer virmidi code has an open race at its output trigger
callback: namely, virmidi keeps only one event packet for processing
while it doesn't protect for concurrent output trigger calls.
snd_virmidi_output_trigger() tries to process the previously
unfinished event before starting encoding the given MIDI stream, but
this is done without any lock. Meanwhile, if another rawmidi stream
starts the output trigger, this proceeds further, and overwrites the
event package that is being processed in another thread. This
eventually corrupts and may lead to the invalid memory access if the
event type is like SYSEX.
The fix is just to move the spinlock to cover both the pending event
and the new stream.
The bug was spotted by a new fuzzer, RaceFuzzer.

Since snd_pcm_ioctl_xfern_compat() has no PCM state check, it may go
further and hit the sanity check pcm_sanity_check() when the ioctl is

triggered by syzbot, depending on kconfig.
The lack of PCM state check there was just an oversight. Although
it's no real crash, the spurious kernel warning is annoying, so let's
add the proper check.

commit bd2e778c9ee361c23ccb2b10591712e129d97893 upstream.
ECC is only calculated for written pages. As erased pages are not
actively written the ECC is always invalid. For this purpose the
Hardware BCH unit is able to check for erased pages and does not raise
an ECC error in this case. This behaviour can be influenced using the
BCH_MODE register which sets the number of allowed bitflips in an erased
page. Unfortunately the unit is not capable of fixing the bitflips in
memory.
To avoid complete software checks for erased pages, we can simply check
buffers with uncorrectable ECC errors because we know that any erased
page with errors is uncorrectable by the BCH unit.
This patch adds the generic nand_check_erased_ecc_chunk() to gpmi-nand
to correct erased pages. To have the valid data in the buffer before
using them, this patch moves the read_page_swap_end() call before the
ECC status checking for-loop.

commit 7eccb738fce57cbe53ed903ccf43f9ab257b15b3 upstream.
Rx data frames notified through HTT_T2H_MSG_TYPE_RX_IND and
HTT_T2H_MSG_TYPE_RX_FRAG_IND expect PN/TSC check to be done
on host (mac80211) rather than firmware. Rebuild cipher header
in every received data frames (that are notified through those
HTT interfaces) from the rx_hdr_status tlv available in the
rx descriptor of the first msdu. Skip setting RX_FLAG_IV_STRIPPED
flag for the packets which requires mac80211 PN/TSC check support
and set appropriate RX_FLAG for stripped crypto tail. Hw QCA988X,
QCA9887, QCA99X0, QCA9984, QCA9888 and QCA4019 currently need the
rebuilding of cipher header to perform PN/TSC check for replay
attack.
Please note that removing crypto tail for CCMP-256, GCMP and GCMP-256 ciphers
in raw mode needs to be fixed. Since Rx with these ciphers in raw
mode does not work in the current form even without this patch and
removing crypto tail for these chipers needs clean up, raw mode related
issues in CCMP-256, GCMP and GCMP-256 can be addressed in follow up
patches.
