2020-07-22net: atlantic: fix PTP on AQC10XEgor Pomozov
This patch fixes PTP on AQC10X. PTP support on AQC10X requires FW involvement and FW configures the TPS data arb mode itself. So we must make sure driver doesn't touch TPS data arb mode on AQC10x if PTP is enabled. Otherwise, there are no timestamps even though packets are flowing.

2020-07-22sctp: shrink stream outq when fails to do addstream reconfXin Long
When adding a stream with stream reconf, the new stream firstly is in CLOSED state but new out chunks can still be enqueued. Then once gets the confirmation from the peer, the state will change to OPEN. However, if the peer denies, it needs to roll back the stream. But when doing that, it only sets the stream outcnt back, and the chunks already in the new stream don't get purged. It caused these chunks can still be dequeued in sctp_outq_dequeue_data(). As its stream is still in CLOSE, the chunk will be enqueued to the head again by sctp_outq_head_data(). This chunk will never be sent out, and the chunks after it can never be dequeued. The assoc will be 'hung' in a dead loop of sending this chunk. To fix it, this patch is to purge these chunks already in the new stream by calling sctp_stream_shrink_out() when failing to do the addstream reconf.

It's not necessary to go list_for_each for outq->out_chunk_list when new outcnt >= old outcnt, as no chunk with higher sid than new (outcnt - 1) exists in the outqueue.

2020-07-22enetc: Remove the mdio bus on PF probe bailoutClaudiu Manoil
For ENETC ports that register an external MDIO bus, the bus doesn't get removed on the error bailout path of enetc_pf_probe(). This issue became much more visible after recent: commit 07095c025ac2 ("net: enetc: Use DT protocol information to set up the ports") Before this commit, one could make probing fail on the error path only by having register_netdev() fail, which is unlikely. But after this commit, because it moved the enetc_of_phy_get() call up in the probing sequence, now we can trigger an mdiobus_free() bug just by forcing enetc_alloc_msix() to return error, i.e. with the 'pci=nomsi' kernel bootarg (since ENETC relies on MSI support to work), as the calltrace below shows: kernel BUG at /home/eiz/work/enetc/net/drivers/net/phy/mdio_bus.c:648!

H.J. reported that post 5.7 a segfault of a user space task does not longer dump the Code bytes when /proc/sys/debug/exception-trace is enabled. It prints 'Code: Bad RIP value.' instead. This was broken by a recent change which made probe_kernel_read() reject non-kernel addresses. Update show_opcodes() so it retrieves user space opcodes via copy_from_user_nmi().

2020-07-22x86/stacktrace: Fix reliable check for empty user task stacksJosh Poimboeuf
If a user task's stack is empty, or if it only has user regs, ORC reports it as a reliable empty stack. But arch_stack_walk_reliable() incorrectly treats it as unreliable. That happens because the only success path for user tasks is inside the loop, which only iterates on non-empty stacks. Generally, a user task must end in a user regs frame, but an empty stack is an exception to that rule. Thanks to commit 71c95825289f ("x86/unwind/orc: Fix error handling in __unwind_start()"), unwind_start() now sets state->error appropriately. So now for both ORC and FP unwinders, unwind_done() and !unwind_error() always means the end of the stack was successfully reached. So the success path for kthreads is no longer needed -- it can also be used for empty user tasks.

2020-07-22x86/unwind/orc: Fix ORC for newly forked tasksJosh Poimboeuf
The ORC unwinder fails to unwind newly forked tasks which haven't yet run on the CPU. It correctly reads the 'ret_from_fork' instruction pointer from the stack, but it incorrectly interprets that value as a call stack address rather than a "signal" one, so the address gets incorrectly decremented in the call to orc_find(), resulting in bad ORC data. Fix it by forcing 'ret_from_fork' frames to be signal frames.

2020-07-22ASoC: hdac_hda: fix deadlock after PCM open errorKai Vehmanen
Commit 5bd70440cb0a ("ASoC: soc-dai: revert all changes to DAI startup/shutdown sequence"), introduced a slight change of semantics to DAI startup/shutdown. If startup() returns an error, shutdown() is now called for the DAI. This causes a deadlock in hdac_hda which issues a call to snd_hda_codec_pcm_put() in case open fails. Upon error, soc_pcm_open() will call shutdown(), and pcm_put() ends up getting called twice. Result is a deadlock on pcm->open_mutex, as snd_device_free() gets called from within snd_pcm_open(). Typical task backtrace looks like this: [ 334.244627] snd_pcm_dev_disconnect+0x49/0x340 [snd_pcm] [ 334.244634] __snd_device_disconnect.part.0+0x2c/0x50 [snd] [ 334.244640] __snd_device_free+0x7f/0xc0 [snd] [ 334.244650] snd_hda_codec_pcm_put+0x87/0x120 [snd_hda_codec] [ 334.244660] soc_pcm_open+0x6a0/0xbe0 [snd_soc_core] [ 334.244676] ? dpcm_add_paths.isra.0+0x491/0x590 [snd_soc_core] [ 334.244679] ? kfree+0x9a/0x230 [ 334.244686] dpcm_be_dai_startup+0x255/0x300 [snd_soc_core] [ 334.244695] dpcm_fe_dai_open+0x20e/0xf30 [snd_soc_core] [ 334.244701] ? snd_pcm_hw_rule_muldivk+0x110/0x110 [snd_pcm] [ 334.244709] ? dpcm_be_dai_startup+0x300/0x300 [snd_soc_core] [ 334.244714] ? snd_pcm_attach_substream+0x3c4/0x540 [snd_pcm] [ 334.244719] snd_pcm_open_substream+0x69a/0xb60 [snd_pcm] [ 334.244729] ? snd_pcm_release_substream+0x30/0x30 [snd_pcm] [ 334.244732] ? __mutex_lock_slowpath+0x10/0x10 [ 334.244736] snd_pcm_open+0x1b3/0x3c0 [snd_pcm] Fixes: 5bd70440cb0a ("ASoC: soc-dai: revert all changes to DAI startup/shutdown sequence") Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Rander Wang <rander.wang@linux.intel.com> BugLink: https://github.com/thesofproject/linux/issues/2159 Link: https://lore.kernel.org/r/20200717101950.3885187-3-kai.vehmanen@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
2020-07-22ASoC: hdac_hda: fix memleak on module unloadKai Vehmanen
The hdac_hda remove implementation fails to free the hda codec resources, leading to memleaks at module unload. This gap has been there from the start, commit 6bae5ea94989 ("ASoC: hdac_hda: add asoc extension for legacy HDA codec drivers"). Instead of duplicating the cleanup logic, use the common snd_hda_codec_cleanup_for_unbind() to free the resources. Remove existing code in hdac_hda to cleanup "codec.jackpoll_work" and call to snd_hdac_regmap_exit(), as these are already done in snd_hda_codec_cleanup_for_unbind(). The cleanup is done in ASoC component remove() callback and not in the HDAC bus hdev_detach(). This is done to ensure the codec specific cleanup routines are run before the parent card is freed.

2020-07-22ASoC: intel/skl/hda - fix probe regression on systems without i915Kai Vehmanen
Starting in commit cbc7a6b5a87a ("ASoC: soc-card: add snd_soc_card_add_dai_link()"), error value from ASoc add_dai_link() is no longer ignored. The generic HDA machine driver relied on the old semantics to disable i915 HDMI/DP audio codec at runtime. If no display codec was present, add_dai_link() returned an error, but this was ignored and rest of the card was successfully probed. Fix the problem by changing the machine driver add_dai_link() to not return an error in this case.

2020-07-22i2c: cadence: Clear HOLD bit at correct time in Rx pathRaviteja Narayanam
There are few issues on Zynq SOC observed in the stress tests causing timeout errors. Even though all the data is received, timeout error is thrown. This is due to an IP bug in which the COMP bit in ISR is not set at end of transfer and completion interrupt is not generated. This bug is seen on Zynq platforms when the following condition occurs: Master read & HOLD bit set & Transfer size register reaches '0'. One workaround is to clear the HOLD bit before the transfer size register reaches '0'. The current implementation checks for this at the start of the loop and also only for less than FIFO DEPTH case (ignoring the equal to case). So clear the HOLD bit when the data yet to receive is less than or equal to the FIFO DEPTH. This avoids the IP bug condition.

2020-07-22Revert "i2c: cadence: Fix the hold bit setting"Raviteja Narayanam
This reverts commit d358def706880defa4c9e87381c5bf086a97d5f9. There are two issues with "i2c: cadence: Fix the hold bit setting" commit. 1. In case of combined message request from user space, when the HOLD bit is cleared in cdns_i2c_mrecv function, a STOP condition is sent on the bus even before the last message is started. This is because when the HOLD bit is cleared, the FIFOS are empty and there is no pending transfer. The STOP condition should occur only after the last message is completed. 2. The code added by the commit is redundant. Driver is handling the setting/clearing of HOLD bit in right way before the commit. The setting of HOLD bit based on 'bus_hold_flag' is taken care in cdns_i2c_master_xfer function even before cdns_i2c_msend/cdns_i2c_recv functions. The clearing of HOLD bit is taken care at the end of cdns_i2c_msend and cdns_i2c_recv functions based on bus_hold_flag and byte count. Since clearing of HOLD bit is done after the slave address is written to the register (writing to address register triggers the message transfer), it is ensured that STOP condition occurs at the right time after completion of the pending transfer (last message).

2020-07-22sched: Fix race against ptrace_freeze_trace()Peter Zijlstra
There is apparently one site that violates the rule that only current and ttwu() will modify task->state, namely ptrace_{,un}freeze_traced() will change task->state for a remote task. Oleg explains: "TASK_TRACED/TASK_STOPPED was always protected by siglock. In particular, ttwu(__TASK_TRACED) must be always called with siglock held. That is why ptrace_freeze_traced() assumes it can safely do s/TASK_TRACED/__TASK_TRACED/ under spin_lock(siglock)." This breaks the ordering scheme introduced by commit: dbfb089d360b ("sched: Fix loadavg accounting race") Specifically, the reload not matching no longer implies we don't have to block. Simply things by noting that what we need is a LOAD->STORE ordering and this can be provided by a control dependency. So replace: prev_state = prev->state; raw_spin_lock(&rq->lock); smp_mb__after_spinlock(); /* SMP-MB */ if (... && prev_state && prev_state == prev->state) deactivate_task(); with: prev_state = prev->state; if (... && prev_state) /* CTRL-DEP */ deactivate_task(); Since that already implies the 'prev->state' load must be complete before allowing the 'prev->on_rq = 0' store to become visible.

2020-07-22x86, vmlinux.lds: Page-align end of ..page_aligned sectionsJoerg Roedel
On x86-32 the idt_table with 256 entries needs only 2048 bytes. It is page-aligned, but the end of the .bss..page_aligned section is not guaranteed to be page-aligned. As a result, objects from other .bss sections may end up on the same 4k page as the idt_table, and will accidentially get mapped read-only during boot, causing unexpected page-faults when the kernel writes to them. This could be worked around by making the objects in the page aligned sections page sized, but that's wrong. Explicit sections which store only page aligned objects have an implicit guarantee that the object is alone in the page in which it is placed. That works for all objects except the last one. That's inconsistent. Enforcing page sized objects for these sections would wreckage memory sanitizers, because the object becomes artificially larger than it should be and out of bound access becomes legit. Align the end of the .bss..page_aligned and .data..page_aligned section on page-size so all objects places in these sections are guaranteed to have their own page.

2020-07-21drivers/net/wan/x25_asy: Fix to make it workXie He
This driver is not working because of problems of its receiving code. This patch fixes it to make it work. When the driver receives an LAPB frame, it should first pass the frame to the LAPB module to process. After processing, the LAPB module passes the data (the packet) back to the driver, the driver should then add a one-byte pseudo header and pass the data to upper layers. The changes to the "x25_asy_bump" function and the "x25_asy_data_indication" function are to correctly implement this procedure. Also, the "x25_asy_unesc" function ignores any frame that is shorter than 3 bytes. However the shortest frames are 2-byte long. So we need to change it to allow 2-byte frames to pass.
