2018-12-16net: hns: All ports can not work when insmod hns ko after rmmod.Yonglong Liu2-0/+18
There are two test cases: 1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio, and install them again, must use "ifconfig down/ifconfig up" command pair to bring port to work. This patch calls phy_stop function when init phy to fix this bug. 2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again, all ports can not use anymore, because of the phy devices register failed(phy devices already exists). Phy devices are registered when hns_dsaf installed, this patch removes them when hns_dsaf removed. The two cases are sometimes related, fixing the second case also requires fixing the first case, so fix them together.

2018-12-15net: clear skb->tstamp in forwarding pathsEric Dumazet2-0/+2
Sergey reported that forwarding was no longer working if fq packet scheduler was used. This is caused by the recent switch to EDT model, since incoming packets might have been timestamped by __net_timestamp() __net_timestamp() uses ktime_get_real(), while fq expects packets using CLOCK_MONOTONIC base. The fix is to clear skb->tstamp in forwarding paths. Fixes: 80b14dee2bea ("net: Add a new socket option for a future transmit time.")

2018-12-15net: ipv4: do not handle duplicate fragments as overlappingMichal Kubecek1-6/+12
Since commit 7969e5c40dfd ("ip: discard IPv4 datagrams with overlapping segments.") IPv4 reassembly code drops the whole queue whenever an overlapping fragment is received. However, the test is written in a way which detects duplicate fragments as overlapping so that in environments with many duplicate packets, fragmented packets may be undeliverable. Add an extra test and for (potentially) duplicate fragment, only drop the new fragment rather than the whole queue. Only starting offset and length are checked, not the contents of the fragments as that would be too expensive. For similar reason, linear list ("run") of a rbtree node is not iterated, we only check if the new fragment is a subset of the interval covered by existing consecutive fragments. v2: instead of an exact check iterating through linear list of an rbtree node, only check if the new fragment is subset of the "run" (suggested by Eric Dumazet) Fixes: 7969e5c40dfd ("ip: discard IPv4 datagrams with overlapping segments.")

2018-12-15x86/vdso: Pass --eh-frame-hdr to the linkerAlistair Strachan1-1/+2
Commit 379d98ddf413 ("x86: vdso: Use $LD instead of $CC to link") accidentally broke unwinding from userspace, because ld would strip the .eh_frame sections when linking. Originally, the compiler would implicitly add --eh-frame-hdr when invoking the linker, but when this Makefile was converted from invoking ld via the compiler, to invoking it directly (like vmlinux does), the flag was missed. (The EH_FRAME section is important for the VDSO shared libraries, but not for vmlinux.) Fix the problem by explicitly specifying --eh-frame-hdr, which restores parity with the old method.

tipc_wait_for_cond() drops socket lock before going to sleep, but tsk->group could be freed right after that release_sock(). So we have to re-check and reload tsk->group after it wakes up. After this patch, tipc_wait_for_cond() returns -ERESTARTSYS when tsk->group is NULL, instead of continuing with the assumption of a non-NULL tsk->group.

2018-12-14net: Allow class-e address assignment via ifconfig ioctlDave Taht3-5/+12
While most distributions long ago switched to the iproute2 suite of utilities, which allow class-e (240.0.0.0/4) address assignment, distributions relying on busybox, toybox and other forms of ifconfig cannot assign class-e addresses without this kernel patch. While CIDR has been obsolete for 2 decades, and a survey of all the open source code in the world shows the IN_whatever macros are also obsolete... rather than obsolete CIDR from this ioctl entirely, this patch merely enables class-e assignment, sanely.

2018-12-14scripts/spdxcheck.py: always open files in binary modeThierry Reding1-2/+4
The spdxcheck script currently falls over when confronted with a binary file (such as Documentation/logo.gif). To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).

2018-12-14fs/iomap.c: get/put the page in iomap_page_create/release()Piotr Jaroszynski1-0/+7
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 (https://lkml.kernel.org/r/[email protected]). I only hit this in tests that verify that move_pages() actually moved the pages. The test also got confused by the positive return from move_pages() (it got treated as a success as positive numbers were not expected and not handled) making it a bit harder to track down what's going on.

2018-12-14alpha: fix hang caused by the bootmem removalMike Rapoport2-3/+4
The conversion of alpha to memblock as the early memory manager caused boot to hang as described at [1]. The issue is caused because for CONFIG_DISCTONTIGMEM=y case, memblock_add() is called using memory start PFN that had been rounded down to the nearest 8Mb and it caused memblock to see more memory that is actually present in the system. Besides, memblock allocates memory from high addresses while bootmem was using low memory, which broke the assumption that early allocations are always accessible by the hardware. This patch ensures that memblock_add() is using the correct PFN for the memory start and forces memblock to use bottom-up allocations.

2018-12-14tipc: use lock_sock() in tipc_sk_reinit()Cong Wang1-2/+6
lock_sock() must be used in process context to be race-free with other lock_sock() callers, for example, tipc_release(). Otherwise using the spinlock directly can't serialize a parallel tipc_release(). As it is blocking, we have to hold the sock refcnt before rhashtable_walk_stop() and release it after rhashtable_walk_start().

2018-12-14include/linux/compiler_types.h: don't pollute userspace with macro definitionsXiaozhou Liu1-54/+54
Macros 'inline' and '__gnu_inline' used to be defined in compiler-gcc.h, which was (and is) included entirely in (__KERNEL__ && !__ASSEMBLY__). Commit 815f0ddb346c ("include/linux/compiler*.h: make compiler-*.h mutually exclusive") had those macros exposed to userspace, unintentionally. Then commit a3f8a30f3f00 ("Compiler Attributes: use feature checks instead of version checks") moved '__gnu_inline' back into (__KERNEL__ && !__ASSEMBLY__) and 'inline' was left behind. Since 'inline' depends on '__gnu_inline', compiling error showing "unknown type name ‘__gnu_inline’" will pop up, if userspace somehow includes <linux/compiler.h>. Other macros like __must_check, notrace, etc. are in a similar situation. So just move all these macros back into (__KERNEL__ && !__ASSEMBLY__). Note: 1. This patch only affects what userspace sees. 2. __must_check (when !CONFIG_ENABLE_MUST_CHECK) and noinline_for_stack were once defined in __KERNEL__ only, but we believe that they can be put into !__ASSEMBLY__ too.

2018-12-14xhci: Don't prevent USB2 bus suspend in state check intended for USB3 onlyMathias Nyman1-1/+2
The code to prevent a bus suspend if a USB3 port was still in link training also reacted to USB2 port polling state. This caused bus suspend to busyloop in some cases. USB2 polling state is different from USB3, and should not prevent bus suspend. Limit the USB3 link training state check to USB3 root hub ports only. The origial commit went to stable so this need to be applied there as well Fixes: 2f31a67f01a8 ("usb: xhci: Prevent bus suspend if a port connect change or polling state is detected") Cc: [email protected] Signed-off-by: Mathias Nyman <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
