2022-03-18media: platform: Kconfig: place platform drivers on a submenuMauro Carvalho Chehab2-3/+15
Just like media bus drivers, place platform drivers on a submenu, in order to better organize user-selection: Media drivers ---> *** media drivers *** [*] Media USB Adapters ---> [*] Media PCI Adapters ---> -*- Radio Adapters ---> [*] Media platform devices ---> *** MMC/SDIO DVB adapters *** < > Siano SMS1xxx based MDTV via SDIO interface [*] V4L test drivers ---> [*] DVB test drivers ---> *** FireWire (IEEE 1394) Adapters *** <*> FireDTV and FloppyDTV *** common driver options *** [ ] Enable Remote Controller support for Siano devices [ ] Enable debugfs for smsdvb As this submenu depends on MEDIA_PLATFORM_DRIVERS and defaults to "y", there's no need to change already-existing .config entries, nor touch the several make *_defconfig.

2022-03-18block: limit request dispatch loop durationShin'ichiro Kawasaki1-1/+8
When IO requests are made continuously and the target block device handles requests faster than request arrival, the request dispatch loop keeps on repeating to dispatch the arriving requests very long time, more than a minute. Since the loop runs as a workqueue worker task, the very long loop duration triggers workqueue watchdog timeout and BUG [1]. To avoid the very long loop duration, break the loop periodically. When opportunity to dispatch requests still exists, check need_resched(). If need_resched() returns true, the dispatch loop already consumed its time slice, then reschedule the dispatch work and break the loop. With heavy IO load, need_resched() does not return true for 20~30 seconds. To cover such case, check time spent in the dispatch loop with jiffies. If more than 1 second is spent, reschedule the dispatch work and break the loop. [1] [ 609.691437] BUG: workqueue lockup - pool cpus=10 node=1 flags=0x0 nice=-20 stuck for 35s!

2022-03-18io_uring: manage provided buffers strictly orderedJens Axboe1-62/+92
Workloads using provided buffers benefit from using and returning buffers in the right order, and so does TLBs for that matter. Manage the internal buffer list in a straight list, rather than use the head buffer as the insertion node. Use a hashed list for the buffer group IDs instead of xarray, the overhead is much lower this way. xarray provides internal locking and other trickery that is handy for some uses cases, but io_uring already locks internally for the buffer manipulation and needs none of that. This is good for about a 2% reduction in overhead, combination of the improved management and the fact that the workload has an easier time bundling back provided buffers.

2022-03-17mm: swap: get rid of livelock in swapin readaheadGuo Ziliang1-1/+1
In our testing, a livelock task was found. Through sysrq printing, same stack was found every time, as follows: __swap_duplicate+0x58/0x1a0 swapcache_prepare+0x24/0x30 __read_swap_cache_async+0xac/0x220 read_swap_cache_async+0x58/0xa0 swapin_readahead+0x24c/0x628 do_swap_page+0x374/0x8a0 __handle_mm_fault+0x598/0xd60 handle_mm_fault+0x114/0x200 do_page_fault+0x148/0x4d0 do_translation_fault+0xb0/0xd4 do_mem_abort+0x50/0xb0 The reason for the livelock is that swapcache_prepare() always returns EEXIST, indicating that SWAP_HAS_CACHE has not been cleared, so that it cannot jump out of the loop. We suspect that the task that clears the SWAP_HAS_CACHE flag never gets a chance to run. We try to lower the priority of the task stuck in a livelock so that the task that clears the SWAP_HAS_CACHE flag will run. The results show that the system returns to normal after the priority is lowered. In our testing, multiple real-time tasks are bound to the same core, and the task in the livelock is the highest priority task of the core, so the livelocked task cannot be preempted. Although cond_resched() is used by __read_swap_cache_async, it is an empty function in the preemptive system and cannot achieve the purpose of releasing the CPU. A high-priority task cannot release the CPU unless preempted by a higher-priority task. But when this task is already the highest priority task on this core, other tasks will not be able to be scheduled. So we think we should replace cond_resched() with schedule_timeout_uninterruptible(1), schedule_timeout_interruptible will call set_current_state first to set the task state, so the task will be removed from the running queue, so as to achieve the purpose of giving up the CPU and prevent it from running in kernel mode for too long. (akpm: ugly hack becomes uglier. But it fixes the issue in a backportable-to-stable fashion while we hopefully work on something better) Link: https://lkml.kernel.org/r/20220221111749.1928222-1-cgel.zte@gmail.com Signed-off-by: Guo Ziliang <guo.ziliang@zte.com.cn> Reported-by: Zeal Robot <zealci@zte.com.cn> Reviewed-by: Ran Xiaokai <ran.xiaokai@zte.com.cn> Reviewed-by: Jiang Xuexin <jiang.xuexin@zte.com.cn> Reviewed-by: Yang Yang <yang.yang29@zte.com.cn> Acked-by: Hugh Dickins <hughd@google.com> Cc: Naoya Horiguchi <naoya.horiguchi@nec.com> Cc: Michal Hocko <mhocko@kernel.org> Cc: Minchan Kim <minchan@kernel.org> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Roger Quadros <rogerq@kernel.org> Cc: Ziliang Guo <guo.ziliang@zte.com.cn> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2022-03-17spi: Fix erroneous sgs value with min_t()Biju Das1-2/+2
While computing sgs in spi_map_buf(), the data type used in min_t() for max_seg_size is 'unsigned int' where as that of ctlr->max_dma_len is 'size_t'. min_t(unsigned int,x,y) gives wrong results if one of x/y is 'size_t' Consider the below examples on a 64-bit machine (ie size_t is 64-bits, and unsigned int is 32-bit). case 1) min_t(unsigned int, 5, 0x100000001); case 2) min_t(size_t, 5, 0x100000001); Case 1 returns '1', where as case 2 returns '5'. As you can see the result from case 1 is wrong. This patch fixes the above issue by using the data type of the parameters that are used in min_t with maximum data length.

2022-03-17iavf: Fix hang during reboot/shutdownIvan Vecera1-0/+7
Recent commit 974578017fc1 ("iavf: Add waiting so the port is initialized in remove") adds a wait-loop at the beginning of iavf_remove() to ensure that port initialization is finished prior unregistering net device. This causes a regression in reboot/shutdown scenario because in this case callback iavf_shutdown() is called and this callback detaches the device, makes it down if it is running and sets its state to __IAVF_REMOVE. Later shutdown callback of associated PF driver (e.g. ice_shutdown) is called. That callback calls among other things sriov_disable() that calls indirectly iavf_remove() (see stack trace below). As the adapter state is already __IAVF_REMOVE then the mentioned loop is end-less and shutdown process hangs. The patch fixes this by checking adapter's state at the beginning of iavf_remove() and skips the rest of the function if the adapter is already in remove state (shutdown is in progress). Reproducer: 1. Create VF on PF driven by ice or i40e driver 2. Ensure that the VF is bound to iavf driver 3.

2022-03-17net: mscc: ocelot: fix backwards compatibility with single-chain tc-flower ↵Vladimir Oltean1-1/+15
offload ACL rules can be offloaded to VCAP IS2 either through chain 0, or, since the blamed commit, through a chain index whose number encodes a specific PAG (Policy Action Group) and lookup number. The chain number is translated through ocelot_chain_to_pag() into a PAG, and through ocelot_chain_to_lookup() into a lookup number. The problem with the blamed commit is that the above 2 functions don't have special treatment for chain 0. So ocelot_chain_to_pag(0) returns filter->pag = 224, which is in fact -32, but the "pag" field is an u8. So we end up programming the hardware with VCAP IS2 entries having a PAG of 224. But the way in which the PAG works is that it defines a subset of VCAP IS2 filters which should match on a packet. The default PAG is 0, and previous VCAP IS1 rules (which we offload using 'goto') can modify it. So basically, we are installing filters with a PAG on which no packet will ever match. This is the hardware equivalent of adding filters to a chain which has no 'goto' to it. Restore the previous functionality by making ACL filters offloaded to chain 0 go to PAG 0 and lookup number 0. The choice of PAG is clearly correct, but the choice of lookup number isn't "as before" (which was to leave the lookup a "don't care"). However, lookup 0 should be fine, since even though there are ACL actions (policers) which have a requirement to be used in a specific lookup, that lookup is 0.

Since a 1's complement sum can only produce this result if no bits are set in the received data stream it is fair to treat it as an invalid partial checksum and not pass it up the stack.

Commit b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") added request_firmware() logic in probe() which caused load failure when firmware file is not present in initrd (below), as access to firmware file is not feasible during probe. Direct firmware load for bnx2x/bnx2x-e2-7.13.15.0.fw failed with error -2 Direct firmware load for bnx2x/bnx2x-e2-7.13.21.0.fw failed with error -2 This patch fixes this issue by - 1. Removing request_firmware() logic from the probe() such that .ndo_open() handle it as it used to handle it earlier 2. Given request_firmware() is removed from probe(), so driver has to relax FW version comparisons a bit against the already loaded FW version (by some other PFs of same adapter) to allow different compatible/close enough FWs with which multiple PFs may run with (in different environments), as the given PF who is in probe flow has no idea now with which firmware file version it is going to initialize the device in ndo_open() Link: https://lore.kernel.org/all/46f2d9d9-ae7f-b332-ddeb-b59802be2bab@molgen.mpg.de/ Reported-by: Paul Menzel <pmenzel@molgen.mpg.de> Tested-by: Paul Menzel <pmenzel@molgen.mpg.de> Fixes: b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") Signed-off-by: Manish Chopra <manishc@marvell.com> Signed-off-by: Ariel Elior <aelior@marvell.com> Link: https://lore.kernel.org/r/20220316214613.6884-1-manishc@marvell.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
