2019-01-27net/rose: fix NULL ax25_cb kernel panicBernard Pidoux1-0/+5
When an internally generated frame is handled by rose_xmit(), rose_route_frame() is called: if (!rose_route_frame(skb, NULL)) { dev_kfree_skb(skb); stats->tx_errors++; return NETDEV_TX_OK; } We have the same code sequence in Net/Rom where an internally generated frame is handled by nr_xmit() calling nr_route_frame(skb, NULL). However, in this function NULL argument is tested while it is not in rose_route_frame(). Then kernel panic occurs later on when calling ax25cmp() with a NULL ax25_cb argument as reported many times and recently with syzbot. We need to test if ax25 is NULL before using it.

2019-01-27iomap: get/put the page in iomap_page_create/release()Piotr Jaroszynski1-0/+9
migrate_page_move_mapping() expects pages with private data set to have a page_count elevated by 1. This is what used to happen for xfs through the buffer_heads code before the switch to iomap in commit 82cb14175e7d ("xfs: add support for sub-pagesize writeback without buffer_heads"). Not having the count elevated causes move_pages() to fail on memory mapped files coming from xfs. Make iomap compatible with the migrate_page_move_mapping() assumption by elevating the page count as part of iomap_page_create() and lowering it in iomap_page_release(). It causes the move_pages() syscall to misbehave on memory mapped files from xfs. It does not not move any pages, which I suppose is "just" a perf issue, but it also ends up returning a positive number which is out of spec for the syscall. Talking to Michal Hocko, it sounds like returning positive numbers might be a necessary update to move_pages() anyway though.

Secondary CPU reset vector overlaps part of the double exception handler code, resulting in weird crashes and hangups when running user code. Move exception vectors one page up so that they don't clash with the secondary CPU reset vector. Signed-off-by: Max Filippov <[email protected]>
2019-01-26xtensa: SMP: fix secondary CPU initializationMax Filippov2-14/+25
- add missing memory barriers to the secondary CPU synchronization spin loops; add comment to the matching memory barrier in the boot_secondary and __cpu_die functions; - use READ_ONCE/WRITE_ONCE to access cpu_start_id/cpu_start_ccount instead of reading/writing them directly; - re-initialize cpu_running every time before starting secondary CPU to flush possible previous CPU startup results.

2019-01-25selftests/seccomp: Enhance per-arch ptrace syscall skip testsKees Cook1-15/+57
Passing EPERM during syscall skipping was confusing since the test wasn't actually exercising the errno evaluation -- it was just passing a literal "1" (EPERM). Instead, expand the tests to check both direct value returns (positive, 45000 in this case), and errno values (negative, -ESRCH in this case) to check both fake success and fake failure during syscall skipping.

2019-01-25selftests: cpu-hotplug: fix case where CPUs offline > CPUs presentColin Ian King1-3/+10
The cpu-hotplug test assumes that we can offline the maximum CPU as described by /sys/devices/system/cpu/offline. However, in the case where the number of CPUs exceeds like kernel configuration then the offline count can be greater than the present count and we end up trying to test the offlining of a CPU that is not available to offline. Fix this by testing the maximum present CPU instead. Also, the test currently offlines the CPU and does not online it, so fix this by onlining the CPU after the test.

2019-01-25net/mlx5e: Move to use common phys port names for vport representorsOr Gerlitz3-2/+33
With VF LAG commit 491c37e49b48 "net/mlx5e: In case of LAG, one switch parent id is used for all representors", both uplinks and all the VFs (on both of them) get the same switchdev id. This cause the provisioning system method to identify the rep of a given VF from the parent PF PCI device using switchev id and physical port name to break, since VFm of PF0 will have the (id, name) as VFm of PF1. To fix that, we align to use the framework agreed upstream and set by nfp commit 168c478e107e "nfp: wire get_phys_port_name on representors": $ cat /sys/class/net/eth4_*/phys_port_name p0 pf0vf0 pf0vf1 Now, the names will be different, e.g. pf0vf0 vs. pf1vf0.
