commit 4f32ac2e upstream. 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.

commit 09abfe7b upstream. 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 7d83fb14 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" Fixes: a904b1ca ("xfs: Add support FALLOC_FL_INSERT_RANGE for fallocate") Cc: <stable@vger.kernel.org> # v4.1+ Originally-From: Eric Biggers <ebiggers@google.com> Signed-off-by:

commit d66a270b upstream. Tracepoint should only warn when a kernel API user does not respect the required preconditions (e.g. same tracepoint enabled twice, or called to remove a tracepoint that does not exist). Silence warning in out-of-memory conditions, given that the error is returned to the caller. This ensures that out-of-memory error-injection testing does not trigger warnings in tracepoint.c, which were seen by syzbot.

commit 8f22e525 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. BugLink: http://lkml.kernel.org/r/20180426045223.GA15307@dragonet.kaist.ac.krReported-by:

commit f13876e2 upstream. 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 called right after open. It may eventually spew a kernel warning, as 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 bd2e778c 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. Signed-off-by:

commit 7eccb738 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.

commit f980ebc0 upstream. When HW crypto is used, there's no need for the CCMP/GCMP MIC to be available to mac80211, and the hardware might have removed it already after checking. The MIC is also useless to have when the frame is already decrypted, so allow indicating that it's not present. Since we are running out of bits in mac80211_rx_flags, make the flags field a u64.

commit da6fa7ef upstream. Recent AMD systems support using MWAIT for C1 state. However, MWAIT will not allow deeper cstates than C1 on current systems. play_dead() expects to use the deepest state available. The deepest state available on AMD systems is reached through SystemIO or HALT. If MWAIT is available, it is preferred over the other methods, so the CPU never reaches the deepest possible state. Don't try to use MWAIT to play_dead() on AMD systems. Instead, use CPUIDLE to enter the deepest state advertised by firmware. If CPUIDLE is not available then fallback to HALT. Signed-off-by:

commit 1a512c08 upstream. A bugfix broke the x32 shmid64_ds and msqid64_ds data structure layout (as seen from user space) a few years ago: Originally, __BITS_PER_LONG was defined as 64 on x32, so we did not have padding after the 64-bit __kernel_time_t fields, After __BITS_PER_LONG got changed to 32, applications would observe extra padding. In other parts of the uapi headers we seem to have a mix of those expecting either 32 or 64 on x32 applications, so we can't easily revert the path that broke these two structures. Instead, this patch decouples x32 from the other architectures and moves it back into arch specific headers, partially reverting the even older commit 73a2d096 ("x86: remove all now-duplicate header files"). It's not clear whether this ever made any difference, since at least glibc carries its own (correct) copy of both of these header files, so possibly no application has ever observed the definitions here. Based on a suggestion from H.J. Lu, I tried out the tool from https://github.com/hjl-tools/linux-header to find other such bugs, which pointed out the same bug in statfs(), which also has a separate (correct) copy in glibc.

commit 9c55ad1c upstream. ceph_con_workfn() validates con->state before calling try_read() and then try_write(). However, try_read() temporarily releases con->mutex, notably in process_message() and ceph_con_in_msg_alloc(), opening the window for ceph_con_close() to sneak in, close the connection and release con->sock. When try_write() is called on the assumption that con->state is still valid (i.e. not STANDBY or CLOSED), a NULL sock gets passed to the networking stack: BUG: unable to handle kernel NULL pointer dereference at 0000000000000020 IP: selinux_socket_sendmsg+0x5/0x20 Make sure con->state is valid at the top of try_write() and add an explicit BUG_ON for this, similar to try_read().

commit c656941d upstream. When the desired ratio is less than 256, the savesub (tolerance) in the calculation would become 0. This will then fail the loop- search immediately without reporting any errors. But if the ratio is smaller enough, there is no need to calculate the tolerance because PM divisor alone is enough to get the ratio. So a simple fix could be just to set PM directly instead of going into the loop-search. Reported-by:

commit 46a16a22 upstream. Some Micron chips does not work well wrt Erase suspend for boot blocks. This avoids the issue by not allowing Erase suspend for the boot blocks for the 28F00AP30(1GBit) chip. Signed-off-by:

commit ea04a1db upstream. Fill COEF to change EAPD to verb control. Assigned codec type. This is an additional fix over 92f974df ("ALSA: hda/realtek - New vendor ID for ALC233"). [ More notes: according to Kailang, the chip is 10ec:0235 bonding for ALC233b, which is equivalent with ALC255. It's only used for Lenovo. The chip needs no alc_process_coef_fw() for headset unlike ALC255. ] Signed-off-by:

commit 69fa6f19 upstream. As recently Smatch suggested, one place in HD-audio hwdep ioctl codes may expand the array directly from the user-space value with speculation: sound/pci/hda/hda_local.h:467 get_wcaps() warn: potential spectre issue 'codec->wcaps' As get_wcaps() itself is a fairly frequently called inline function, and there is only one single call with a user-space value, we replace only the latter one to open-code locally with array_index_nospec() hardening in this patch.
