2022-03-22Revert "random: block in /dev/urandom"Linus Torvalds
This reverts commit 6f98a4bfee72c22f50aedb39fb761567969865fe. It turns out we still can't do this. Way too many platforms that don't have any real source of randomness at boot and no jitter entropy because they don't even have a cycle counter. As reported by Guenter Roeck: "This causes a large number of qemu boot test failures for various architectures (arm, m68k, microblaze, sparc32, xtensa are the ones I observed). Common denominator is that boot hangs at 'Saving random seed:'" This isn't hugely unexpected - we tried it, it failed, so now we'll revert it.

2022-03-22jfs: prevent NULL deref in diFreeHaimin Zhang
Add validation check for JFS_IP(ipimap)->i_imap to prevent a NULL deref in diFree since diFree uses it without do any validations. When function jfs_mount calls diMount to initialize fileset inode allocation map, it can fail and JFS_IP(ipimap)->i_imap won't be initialized. Then it calls diFreeSpecial to close fileset inode allocation map inode and it will flow into jfs_evict_inode. Function jfs_evict_inode just validates JFS_SBI(inode->i_sb)->ipimap, then calls diFree. diFree use JFS_IP(ipimap)->i_imap directly, then it will cause a NULL deref.

In the timer callback function tipc_sk_timeout(), we're trying to reschedule another timeout to retransmit a setup request if destination link is congested. But we use the incorrect timeout value (msecs_to_jiffies(100)) instead of (jiffies + msecs_to_jiffies(100)), so that the timer expires immediately, it's irrelevant for original description.

Qian Cai reported a boot crash on arm64 systems, caused by: 0fb3978b0aac ("sched/numa: Fix NUMA topology for systems with CPU-less nodes") The bug is that node_state() must be supplied a valid node_states[] array index, but in task_numa_placement() the max_nid search can fail with NUMA_NO_NODE, which is not a valid index. Fix it by checking that max_nid is a valid index.

The LAN966x has two internal PHYs which are in reset by default. The driver already supported the internal PHYs of the SparX-5. Now add support for the LAN966x, too. Add a new compatible to distinguish them. The LAN966x has additional control bits in this register, thus convert the regmap_write() to regmap_update_bits() to leave the remaining bits untouched. This doesn't change anything for the SparX-5 SoC, because there, the register consists only of reset bits.

2022-03-21net: dsa: fix panic on shutdown if multi-chip tree failed to probeVladimir Oltean
DSA probing is atypical because a tree of devices must probe all at once, so out of N switches which call dsa_tree_setup_routing_table() during probe, for (N - 1) of them, "complete" will return false and they will exit probing early. The Nth switch will set up the whole tree on their behalf. The implication is that for (N - 1) switches, the driver binds to the device successfully, without doing anything. When the driver is bound, the ->shutdown() method may run. But if the Nth switch has failed to initialize the tree, there is nothing to do for the (N - 1) driver instances, since the slave devices have not been created, etc. Moreover, dsa_switch_shutdown() expects that the calling @ds has been in fact initialized, so it jumps at dereferencing the various data structures, which is incorrect. Avoid the ensuing NULL pointer dereferences by simply checking whether the Nth switch has previously set "ds->setup = true" for the switch which is currently shutting down. The entire setup is serialized under dsa2_mutex which we already hold.

2022-03-21openvswitch: always update flow key after natAaron Conole
During NAT, a tuple collision may occur. When this happens, openvswitch will make a second pass through NAT which will perform additional packet modification. This will update the skb data, but not the flow key that OVS uses. This means that future flow lookups, and packet matches will have incorrect data. This has been supported since 5d50aa83e2c8 ("openvswitch: support asymmetric conntrack"). That commit failed to properly update the sw_flow_key attributes, since it only called the ovs_ct_nat_update_key once, rather than each time ovs_ct_nat_execute was called. As these two operations are linked, the ovs_ct_nat_execute() function should always make sure that the sw_flow_key is updated after a successful call through NAT infrastructure.

2022-03-21lib/sbitmap: allocate sb->map via kvzalloc_nodeMing Lei
sbitmap has been used in scsi for replacing atomic operations on sdev->device_busy, so IOPS on some fast scsi storage can be improved. However, sdev->device_busy can be changed in fast path, so we have to allocate the sb->map statically. sdev->device_busy has been capped to 1024, but some drivers may configure the default depth as < 8, then cause each sbitmap word to hold only one bit. Finally 1024 * 128( sizeof(sbitmap_word)) bytes is needed for sb->map, given it is order 5 allocation, sometimes it may fail. Avoid the issue by using kvzalloc_node() for allocating sb->map.

2022-03-21io_uring: remove poll entry from list when canceling allJens Axboe
When the ring is exiting, as part of the shutdown, poll requests are removed. But io_poll_remove_all() does not remove entries when finding them, and since completions are done out-of-band, we can find and remove the same entry multiple times. We do guard the poll execution by poll ownership, but that does not exclude us from reissuing a new one once the previous removal ownership goes away. This can race with poll execution as well, where we then end up seeing req->apoll be NULL because a previous task_work requeue finished the request. Remove the poll entry when we find it and get ownership of it. This prevents multiple invocations from finding it.
