commit 1200a82a upstream. On ISOC endpoints the last trb_pool entry used as a LINK TRB is not getting zeroed out correctly due to memset being called incorrectly and in the wrong place. If pool allocated from DMA was not zero-initialized to begin with this will result in the size and ctrl values being random garbage. Call memset correctly after assignment of the trb_link pointer.

commit a0855054 upstream. When mac80211 wants to ensure that a frame is sent, it calls the flush() callback. Until now, iwldvm implemented this by waiting that all the frames are sent (ACKed or timeout). In case of weak signal, this can take a significant amount of time, delaying the next connection (in case of roaming). Many users have reported that the flush would take too long leading to the following error messages to be printed: iwlwifi 0000:03:00.0: fail to flush all tx fifo queues Q 2 iwlwifi 0000:03:00.0: Current SW read_ptr 161 write_ptr 201 iwl data: 00000000: 00 00 00 00 00 00 00 00 fe ff 01 00 00 00 00 00 [snip] iwlwifi 0000:03:00.0: FH TRBs(0) = 0x00000000 [snip] iwlwifi 0000:03:00.0: Q 0 is active and mapped to fifo 3 ra_tid 0x0000 [9,9] [snip] Instead of waiting for these packets, simply drop them. This significantly improves the responsiveness of the network. Note that all the queues are flushed, but the VO one. This is not typically used by the applications and it likely contains management frames that are useful for connection or roaming. This bug is tracked here: https://bugzilla.kernel.org/show_bug.cgi?id=56581 But it is duplicated in distributions' trackers.

commit 9180ac50 upstream. The LTR is the handshake between the device and the root complex about the latency allowed when the bus exits power save. This configuration was missing and this led to high latency in the link power up. The end user could experience high latency in the network because of this. Signed-off-by:

commit 51904b08 upstream. Unknown operation numbers are caught in nfsd4_decode_compound() which sets op->opnum to OP_ILLEGAL and op->status to nfserr_op_illegal. The error causes the main loop in nfsd4_proc_compound() to skip most processing. But nfsd4_proc_compound also peeks ahead at the next operation in one case and doesn't take similar precautions there.

commit a3058a5d upstream. During FunctionFS bind, ffs_data_get() function was called twice (in functionfs_bind() and in ffs_do_functionfs_bind()), while on unbind ffs_data_put() was called once (in functionfs_unbind() function). In result refcount never reached value 0, and ffs memory resources has been never released. Since ffs_data_get() call in ffs_do_functionfs_bind() is redundant and not neccessary, we remove it to have equal number of gets ans puts, and free allocated memory after refcount reach 0.

commit b01ff5cb upstream. This reverts commit 02dae36a. That commit is bogus in two ways: 1) There's no way dwc3-omap's ->suspend() can cause any effect on xhci's ->suspend(). Linux device driver model guarantees that a parent's ->suspend() will only be called after all children are suspended. dwc3-omap is the parent of the parent of xhci. 2) When implementing Deep Sleep states where context is lost, USBOTGSS_IRQ0 register, well, looses context so we _must_ rewrite it otherwise core IRQs will never be reenabled and USB will appear to be dead.

commit d2e6d62c upstream. commit c58d80f5 ("usb: musb: Ensure that cppi41 timer gets armed on premature DMA TX irq") fixed hrtimer scheduling bug. There is one left which does not trigger that often. The following scenario is still possible: lock(&x->lock); hrtimer_start(&x->t); unlock(&x->lock); expires: t->function(); lock(&x->lock); lock(&x->lock); if (!hrtimer_queued(&x->t)) hrtimer_start(&x->t); unlock(&x->lock); if (!list_empty(x->early_tx_list)) ret = HRTIMER_RESTART; -> hrtimer_forward_now(...) } else ret = HRTIMER_NORESTART; unlock(&x->lock); and the timer callback returns HRTIMER_RESTART for an armed timer. This is wrong and we run into the BUG_ON() in __run_hrtimer(). This can happens on SMP or PREEMPT-RT. The patch fixes the problem by only starting the timer if the timer is not yet queued.

commit b47dcbdc upstream. If the TSC is unusable or disabled, then this patch fixes: - Confusion while trying to clear old APIC interrupts. - Division by zero and incorrect programming of the TSC deadline timer. This fixes boot if the CPU has a TSC deadline timer but a missing or broken TSC. The failure to boot can be observed with qemu using -cpu qemu64,-tsc,+tsc-deadline This also happens to me in nested KVM for unknown reasons. With this patch, I can boot cleanly (although without a TSC). Signed-off-by:

commit a5b7616c upstream. m25p80's device ID table is now spi_nor_ids, defined in spi-nor. The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80. Fixes: 03e296f6 ("mtd: m25p80: use the SPI nor framework") Signed-off-by:

commit 6cab7a37 upstream. `do_cmd_ioctl()`, the handler for the `COMEDI_CMD` ioctl can incorrectly call the Comedi subdevice's `do_cmd()` handler with a NULL channel list pointer. This is a regression as the `do_cmd()` handler has never been expected to deal with that, leading to a kernel OOPS when it tries to dereference it. A NULL channel list pointer is allowed for the `COMEDI_CMDTEST` ioctl, handled by `do_cmdtest_ioctl()` and the subdevice's `do_cmdtest()` handler, but not for the `COMEDI_CMD` ioctl and its handlers. Both `do_cmd_ioctl()` and `do_cmdtest_ioctl()` call `__comedi_get_user_chanlist()` to copy the channel list from user memory into dynamically allocated kernel memory and check it for consistency. That function currently returns 0 if the `user_chanlist` parameter (pointing to the channel list in user memory) is NULL. That's fine for `do_cmdtest_ioctl()`, but `do_cmd_ioctl()` incorrectly assumes the kernel copy of the channel list has been set-up correctly. Fix it by not allowing the `user_chanlist` parameter to be NULL in `__comedi_get_user_chanlist()`, and only calling it from `do_cmdtest_ioctl()` if the parameter is non-NULL. Thanks to Bernd Porr for reporting the bug via an initial patch sent privately. Fixes: c6cd0eef ("staging: comedi: comedi_fops: introduce __comedi_get_user_chanlist()") Reported-by:

commit c7abf25a upstream. It affects non-(V)HT rates and can lead to selecting an rts_cts rate that is not a basic rate or way superior to the reference rate (ATM rates[0] used for the 1st attempt of the protected frame data). E.g, assuming drivers register growing (bitrate) sorted tables of ieee80211_rate-s, having : - rates[0].idx == d'2 and basic_rates == b'10100 will select rts_cts idx b'10011 & ~d'(BIT(2)-1), i.e. 1, likewise - rates[0].idx == d'2 and basic_rates == b'10001 will select rts_cts idx b'10000 The first is not a basic rate and the second is > rates[0]. Also, wrt severity of the addressed misbehavior, ATM we only have one rts_cts_rate_idx rather than one per rate table entry, so this idx might still point to bitrates > rates[1..MAX_RATES].
