Similarly to other recently fixed drivers make sure we don't try to access XDP or page pool APIs when NAPI budget is 0. NAPI budget of 0 may mean that we are in netpoll. This may result in running software IRQs in hard IRQ context, leading to deadlocks or crashes. To make sure bnapi->tx_pkts don't get wiped without handling the events, move clearing the field into the handler itself. Remember to clear tx_pkts after reset (bnxt_enable_napi()) as it's technically possible that netpoll will accumulate some tx_pkts and then a reset will happen, leaving tx_pkts out of sync with reality.

2023-07-31scsi: core: Fix legacy /proc parsing buffer overflowTony Battersby
(lightly modified commit message mostly by Linus Torvalds) The parsing code for /proc/scsi/scsi is disgusting and broken. We should have just used 'sscanf()' or something simple like that, but the logic may actually predate our kernel sscanf library routine for all I know. It certainly predates both git and BK histories. And we can't change it to be something sane like that now, because the string matching at the start is done case-insensitively, and the separator parsing between numbers isn't done at all, so *any* separator will work, including a possible terminating NUL character. This interface is root-only, and entirely for legacy use, so there is absolutely no point in trying to tighten up the parsing. Because any separator has traditionally worked, it's entirely possible that people have used random characters rather than the suggested space. So don't bother to try to pretty it up, and let's just make a minimal patch that can be back-ported and we can forget about this whole sorry thing for another two decades. Just make it at least not read past the end of the supplied data.

2023-07-31scsi: storvsc: Fix handling of virtual Fibre Channel timeoutsMichael Kelley
Hyper-V provides the ability to connect Fibre Channel LUNs to the host system and present them in a guest VM as a SCSI device. I/O to the vFC device is handled by the storvsc driver. The storvsc driver includes a partial integration with the FC transport implemented in the generic portion of the Linux SCSI subsystem so that FC attributes can be displayed in /sys. However, the partial integration means that some aspects of vFC don't work properly. Unfortunately, a full and correct integration isn't practical because of limitations in what Hyper-V provides to the guest. In particular, in the context of Hyper-V storvsc, the FC transport timeout function fc_eh_timed_out() causes a kernel panic because it can't find the rport and dereferences a NULL pointer. The original patch that added the call from storvsc_eh_timed_out() to fc_eh_timed_out() is faulty in this regard. In many cases a timeout is due to a transient condition, so the situation can be improved by just continuing to wait like with other I/O requests issued by storvsc, and avoiding the guaranteed panic. For a permanent failure, continuing to wait may result in a hung thread instead of a panic, which again may be better. So fix the panic by removing the storvsc call to fc_eh_timed_out(). This allows storvsc to keep waiting for a response. The change has been tested by users who experienced a panic in fc_eh_timed_out() due to transient timeouts, and it solves their problem. In the future we may want to deprecate the vFC functionality in storvsc since it can't be fully fixed. But it has current users for whom it is working well enough, so it should probably stay for a while longer.

He also mentioned that "ports" and "port", but added new "ports" needs special handling. Using "ports" vs "port" are different, not compatible on this driver. This means we need both on Doc. Thus, there is no update for these.
2023-07-31ASoC: wm8960: Make automatic the default clocking modeMark Brown
The wm8960 driver supports an automatic clocking mode which will use the MCLK directly where possible and fall back to the PLL if there is no suitable configuration directly using the MCLK. Clock 0 will be used by the generic cards when configuring things, currently this is a MCLK only mode but using AUTO mode would be more functional. Since the driver still prefers to use MCLK directly where possible there should be no negative impact on systems which are able to use MCLK directly. As far as I can see nothing is using the system clock as part of the ABI, the only reference I can see to a mode in a machine driver is the Freescale i.MX card which uses the automatic mode with an explicit in kernel call using the constant so will be unaffected.

2023-07-31net: usb: lan78xx: reorder cleanup operations to avoid UAF bugsDuoming Zhou
The timer dev->stat_monitor can schedule the delayed work dev->wq and the delayed work dev->wq can also arm the dev->stat_monitor timer. When the device is detaching, the net_device will be deallocated. but the net_device private data could still be dereferenced in delayed work or timer handler. As a result, the UAF bugs will happen. One racy situation is shown below: (Thread 1) | (Thread 2) lan78xx_stat_monitor() | ... | lan78xx_disconnect() lan78xx_defer_kevent() | ... ... | cancel_delayed_work_sync(&dev->wq); schedule_delayed_work() | ... (wait some time) | free_netdev(net); //free net_device lan78xx_delayedwork() | //use net_device private data | dev-> //use | Although we use cancel_delayed_work_sync() to cancel the delayed work in lan78xx_disconnect(), it could still be scheduled in timer handler lan78xx_stat_monitor(). Another racy situation is shown below: (Thread 1) | (Thread 2) lan78xx_delayedwork | mod_timer() | lan78xx_disconnect() | cancel_delayed_work_sync() (wait some time) | if (timer_pending(&dev->stat_monitor)) | del_timer_sync(&dev->stat_monitor); lan78xx_stat_monitor() | ... lan78xx_defer_kevent() | free_netdev(net); //free //use net_device private data| dev-> //use | Although we use del_timer_sync() to delete the timer, the function timer_pending() returns 0 when the timer is activated. As a result, the del_timer_sync() will not be executed and the timer could be re-armed. In order to mitigate this bug, We use timer_shutdown_sync() to shutdown the timer and then use cancel_delayed_work_sync() to cancel the delayed work. As a result, the net_device could be deallocated safely. What's more, the dev->flags is set to EVENT_DEV_DISCONNECT in lan78xx_disconnect(). But it could still be set to EVENT_STAT_UPDATE in lan78xx_stat_monitor(). So this patch put the set_bit() behind timer_shutdown_sync().

2023-07-31RDMA/umem: Set iova in ODP flowMichael Guralnik
Fixing the ODP registration flow to set the iova correctly. The calculation in ib_umem_num_dma_blocks() function assumes the iova of the umem is set correctly. When iova is not set, the calculation in ib_umem_num_dma_blocks() is equivalent to length/page_size, which is true only when memory is aligned. For unaligned memory, iova must be set for the ALIGN() in the ib_umem_num_dma_blocks() to take effect and return a correct value. mlx5_ib uses ib_umem_num_dma_blocks() to decide the mkey size to use for the MR. Without this fix, when registering unaligned ODP MR, a wrong size mkey might be chosen and this might cause the UMR to fail. UMR would fail over insufficient size to update the mkey translation: infiniband mlx5_0: dump_cqe:273:(pid 0): dump error cqe 00000000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00000020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00000030: 00 00 00 00 0f 00 78 06 25 00 00 58 00 da ac d2 infiniband mlx5_0: mlx5_ib_post_send_wait:806:(pid 20311): reg umr failed (6) infiniband mlx5_0: pagefault_real_mr:661:(pid 20311): Failed to update mkey page tables Fixes: f0093fb1a7cb ("RDMA/mlx5: Move mlx5_ib_cont_pages() to the creation of the mlx5_ib_mr") Fixes: a665aca89a41 ("RDMA/umem: Split ib_umem_num_pages() into ib_umem_num_dma_blocks()") Signed-off-by: Artemy Kovalyov <artemyko@nvidia.com> Signed-off-by: Michael Guralnik <michaelgur@nvidia.com> Link: https://lore.kernel.org/r/3d4be7ca2155bf239dd8c00a2d25974a92c26ab8.1689757344.git.leon@kernel.org Signed-off-by: Leon Romanovsky <leon@kernel.org>

2023-07-31net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX.Kuniyuki Iwashima
syzkaller found zero division error [0] in div_s64_rem() called from get_cycle_time_elapsed(), where sched->cycle_time is the divisor. We have tests in parse_taprio_schedule() so that cycle_time will never be 0, and actually cycle_time is not 0 in get_cycle_time_elapsed(). The problem is that the types of divisor are different; cycle_time is s64, but the argument of div_s64_rem() is s32. syzkaller fed this input and 0x100000000 is cast to s32 to be 0. @TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000} We use s64 for cycle_time to cast it to ktime_t, so let's keep it and set max for cycle_time. While at it, we prevent overflow in setup_txtime() and add another test in parse_taprio_schedule() to check if cycle_time overflows. Also, we add a new tdc test case for this issue.

2023-07-30nfsd: Fix reading via spliceDavid Howells
nfsd_splice_actor() has a clause in its loop that chops up a compound page into individual pages such that if the same page is seen twice in a row, it is discarded the second time. This is a problem with the advent of shmem_splice_read() as that inserts zero_pages into the pipe in lieu of pages that aren't present in the pagecache. Fix this by assuming that the last page is being extended only if the currently stored length + starting offset is not currently on a page boundary. This can be tested by NFS-exporting a tmpfs filesystem on the test machine and truncating it to more than a page in size (eg. truncate -s 8192) and then reading it by NFS. The first page will be all zeros, but thereafter garbage will be read. Note: I wonder if we can ever get a situation now where we get a splice that gives us contiguous parts of a page in separate actor calls. As NFSD can only be splicing from a file (I think), there are only three sources of the page: copy_splice_read(), shmem_splice_read() and file_splice_read(). The first allocates pages for the data it reads, so the problem cannot occur; the second should never see a partial page; and the third waits for each page to become available before we're allowed to read from it.
