net: usb: rtl8150: set random MAC address when set_ethernet_addr() fails

2020-10-14T07:51:14Z

commit f45a4248ea4cc13ed50618ff066849f9587226b2 upstream. When get_registers() fails in set_ethernet_addr(),the uninitialized value of node_id gets copied over as the address. So, check the return value of get_registers(). If get_registers() executed successfully (i.e., it returns sizeof(node_id)), copy over the MAC address using ether_addr_copy() (instead of using memcpy()). Else, if get_registers() failed instead, a randomly generated MAC address is set as the MAC address instead.

mm: khugepaged: recalculate min_free_kbytes after memory hotplug as expected by khugepaged

2020-10-14T07:51:14Z

commit 4aab2be0983031a05cb4a19696c9da5749523426 upstream. When memory is hotplug added or removed the min_free_kbytes should be recalculated based on what is expected by khugepaged. Currently after hotplug, min_free_kbytes will be set to a lower default and higher default set when THP enabled is lost. This change restores min_free_kbytes as expected for THP consumers.

mmc: core: don't set limits.discard_granularity as 0

2020-10-14T07:51:14Z

[ Upstream commit 4243219141b67d7c2fdb2d8073c17c539b9263eb ] In mmc_queue_setup_discard() the mmc driver queue's discard_granularity might be set as 0 (when card->pref_erase > max_discard) while the mmc device still declares to support discard operation. This is buggy and triggered the following kernel warning message, WARNING: CPU: 0 PID: 135 at __blkdev_issue_discard+0x200/0x294 CPU: 0 PID: 135 Comm: f2fs_discard-17 Not tainted 5.9.0-rc6 #1 Hardware name: Google Kevin (DT) pstate: 00000005 (nzcv daif -PAN -UAO BTYPE=--) pc : __blkdev_issue_discard+0x200/0x294 lr : __blkdev_issue_discard+0x54/0x294 sp : ffff800011dd3b10 x29: ffff800011dd3b10 x28: 0000000000000000 x27: ffff800011dd3cc4 x26: ffff800011dd3e18 x25: 000000000004e69b x24: 0000000000000c40 x23: ffff0000f1deaaf0 x22: ffff0000f2849200 x21: 00000000002734d8 x20: 0000000000000008 x19: 0000000000000000 x18: 0000000000000000 x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 x14: 0000000000000394 x13: 0000000000000000 x12: 0000000000000000 x11: 0000000000000000 x10: 00000000000008b0 x9 : ffff800011dd3cb0 x8 : 000000000004e69b x7 : 0000000000000000 x6 : ffff0000f1926400 x5 : ffff0000f1940800 x4 : 0000000000000000 x3 : 0000000000000c40 x2 : 0000000000000008 x1 : 00000000002734d8 x0 : 0000000000000000 Call trace: __blkdev_issue_discard+0x200/0x294 __submit_discard_cmd+0x128/0x374 __issue_discard_cmd_orderly+0x188/0x244 __issue_discard_cmd+0x2e8/0x33c issue_discard_thread+0xe8/0x2f0 kthread+0x11c/0x120 ret_from_fork+0x10/0x1c ---[ end trace e4c8023d33dfe77a ]--- This patch fixes the issue by setting discard_granularity as SECTOR_SIZE instead of 0 when (card->pref_erase > max_discard) is true. Now no more complain from __blkdev_issue_discard() for the improper value of discard granularity. This issue is exposed after commit b35fd7422c2f ("block: check queue's limits.discard_granularity in __blkdev_issue_discard()"), a "Fixes:" tag is also added for the commit to make sure people won't miss this patch after applying the change of __blkdev_issue_discard().

perf: Fix task_function_call() error handling

2020-10-14T07:51:14Z

[ Upstream commit 6d6b8b9f4fceab7266ca03d194f60ec72bd4b654 ] The error handling introduced by commit: 2ed6edd33a21 ("perf: Add cond_resched() to task_function_call()") looses any return value from smp_call_function_single() that is not {0, -EINVAL}. This is a problem because it will return -EXNIO when the target CPU is offline. Worse, in that case it'll turn into an infinite loop.

rxrpc: Fix server keyring leak

rxrpc: Fix some missing _bh annotations on locking conn->state_lock

[ Upstream commit fa1d113a0f96f9ab7e4fe4f8825753ba1e34a9d3 ] conn->state_lock may be taken in softirq mode, but a previous patch replaced an outer lock in the response-packet event handling code, and lost the _bh from that when doing so.

rxrpc: Fix rxkad token xdr encoding

2020-10-14T07:51:13Z

[ Upstream commit 56305118e05b2db8d0395bba640ac9a3aee92624 ] The session key should be encoded with just the 8 data bytes and no length; ENCODE_DATA precedes it with a 4 byte length, which confuses some existing tools that try to parse this format. Add an ENCODE_BYTES macro that does not include a length, and use it for the key. Also adjust the expected length. Note that commit 774521f353e1d ("rxrpc: Fix an assertion in rxrpc_read()") had fixed a BUG by changing the length rather than fixing the encoding. The original length was correct.
