2018-09-12s390/qeth: use vzalloc for QUERY OAT bufferWenjia Zhang
qeth_query_oat_command() currently allocates the kernel buffer for the SIOC_QETH_QUERY_OAT ioctl with kzalloc. So on systems with fragmented memory, large allocations may fail (eg. the qethqoat tool by default uses 132KB). Solve this issue by using vzalloc, backing the allocation with non-contiguous memory.

2018-09-12x86/efi: Load fixmap GDT in efi_call_phys_epilog() before setting %cr3Guenter Roeck
Commit eeb89e2bb1ac ("x86/efi: Load fixmap GDT in efi_call_phys_epilog()") moved loading the fixmap in efi_call_phys_epilog() after load_cr3() since it was assumed to be more logical. Turns out this is incorrect: In efi_call_phys_prolog(), the gdt with its physical address is loaded first, and when the %cr3 is reloaded in _epilog from initial_page_table to swapper_pg_dir again the gdt is no longer mapped. This results in a triple fault if an interrupt occurs after load_cr3() and before load_fixmap_gdt(0). Calling load_fixmap_gdt(0) first restores the execution order prior to commit eeb89e2bb1ac and fixes the problem.

2018-09-12tracing/Makefile: Fix handling redefinition of CC_FLAGS_FTRACEPaulo Zanoni
As a Kernel developer, I make heavy use of "make targz-pkg" in order to locally compile and remotely install my development Kernels. The nice feature I rely on is that after a normal "make", "make targz-pkg" only generates the tarball without having to recompile everything. That was true until commit f28bc3c32c05 ("tracing: Handle CC_FLAGS_FTRACE more accurately"). After it, running "make targz-pkg" after "make" will recompile the whole Kernel tree, making my development workflow much slower. The Kernel is choosing to recompile everything because it claims the command line has changed. A diff of the .cmd files show a repeated -mfentry in one of the files. That is because "make targz-pkg" calls "make modules_install" and the environment is already populated with the exported variables, CC_FLAGS_FTRACE being one of them. Then, -mfentry gets duplicated because it is not protected behind an ifndef block, like -pg. To complicate the problem a little bit more, architectures can define their own version CC_FLAGS_FTRACE, so our code not only has to consider recursive Makefiles, but also architecture overrides. So in this patch we move CC_FLAGS_FTRACE up and unconditionally define it to -pg. Then we let the architecture Makefiles possibly override it, and finally append the extra options later. This ensures the variable is always fully redefined at each invocation so recursive Makefiles don't keep appending, and hopefully it maintains the intended behavior on how architectures can override the defaults.. Thanks Steven Rostedt and Vasily Gorbik for the help on this regression.

2018-09-12firmware: Fix security issue with request_firmware_into_buf()Rishabh Bhatnagar
When calling request_firmware_into_buf() with the FW_OPT_NOCACHE flag it is expected that firmware is loaded into buffer from memory. But inside alloc_lookup_fw_priv every new firmware that is loaded is added to the firmware cache (fwc) list head. So if any driver requests a firmware that is already loaded the code iterates over the above mentioned list and it can end up giving a pointer to other device driver's firmware buffer. Also the existing copy may either be modified by drivers, remote processors or even freed. This causes a potential security issue with batched requests when using request_firmware_into_buf. Fix alloc_lookup_fw_priv to not add to the fwc head list if FW_OPT_NOCACHE is set, and also don't do the lookup in the list.

2018-09-12rds: fix two RCU related problemsCong Wang
When a rds sock is bound, it is inserted into the bind_hash_table which is protected by RCU. But when releasing rds sock, after it is removed from this hash table, it is freed immediately without respecting RCU grace period. This could cause some use-after-free as reported by syzbot. Mark the rds sock with SOCK_RCU_FREE before inserting it into the bind_hash_table, so that it would be always freed after a RCU grace period. The other problem is in rds_find_bound(), the rds sock could be freed in between rhashtable_lookup_fast() and rds_sock_addref(), so we need to extend RCU read lock protection in rds_find_bound() to close this race condition.

After system suspend, sometimes the r8169 doesn't work when ethernet cable gets pluggued. This issue happens because rtl_reset_work() doesn't get called from rtl8169_runtime_resume(), after system suspend. In rtl_task(), RTL_FLAG_TASK_* only gets cleared if this condition is met: if (!netif_running(dev) || !test_bit(RTL_FLAG_TASK_ENABLED, tp->wk.flags)) ... If RTL_FLAG_TASK_ENABLED was cleared during system suspend while RTL_FLAG_TASK_RESET_PENDING was set, the next rtl_schedule_task() won't schedule task as the flag is still there.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for you net tree: 1) Remove duplicated include at the end of UDP conntrack, from Yue Haibing. 2) Restore conntrack dependency on xt_cluster, from Martin Willi. 3) Fix splat with GSO skbs from the checksum target, from Florian Westphal. 4) Rework ct timeout support, the template strategy to attach custom timeouts is not correct since it will not work in conjunction with conntrack zones and we have a possible free after use when removing the rule due to missing refcounting. To fix these problems, do not use conntrack template at all and set custom timeout on the already valid conntrack object. This fix comes with a preparation patch to simplify timeout adjustment by initializating the first position of the timeout array for all of the existing trackers. Patchset from Florian Westphal. 5) Fix missing dependency on from IPv4 chain NAT type, from Florian. 6) Release chain reference counter from the flush path, from Taehee Yoo. 7) After flushing an iptables ruleset, conntrack hooks are unregistered and entries are left stale to be cleaned up by the timeout garbage collector. No TCP tracking is done on established flows by this time. If ruleset is reloaded, then hooks are registered again and TCP tracking is restored, which considers packets to be invalid. Clear window tracking to exercise TCP flow pickup from the middle given that history is lost for us. Again from Florian. 8) Fix crash from netlink interface with CONFIG_NF_CONNTRACK_TIMEOUT=y and CONFIG_NF_CT_NETLINK_TIMEOUT=n. 9) Broken CT target due to returning incorrect type from ctnl_timeout_find_get(). 10) Solve conntrack clash on NF_REPEAT verdicts too, from Michal Vaner. 11) Missing conversion of hashlimit sysctl interface to new API, from Cong Wang. ==================== Signed-off-by: David S.

2018-09-11perf tools: Fix maps__find_symbol_by_name()Adrian Hunter
Commit 1c5aae7710bb ("perf machine: Create maps for x86 PTI entry trampolines") revealed a problem with maps__find_symbol_by_name() that resulted in probes not being found e.g. $ sudo perf probe xsk_mmap xsk_mmap is out of .text, skip it. Probe point 'xsk_mmap' not found. Error: Failed to add events. maps__find_symbol_by_name() can optionally return the map of the found symbol. It can get the map wrong because, in fact, the symbol is found on the map's dso, not allowing for the possibility that the dso has more than one map. Fix by always checking the map contains the symbol.

2018-09-11staging: vboxvideo: Change address of scanout buffer on page-flipHans de Goede
Commit 2408898e3b6c ("staging: vboxvideo: Add page-flip support") only calls vbox_crtc_do_set_base() on page-flips, but despite that function's name it only pins the new fb, unpins the old fb and sets vbox_crtc->fb_offset. It does not program the hardware to scan out at the new vbox_crtc->fb_offset value. This was causing only every other frame (assuming page-flipping between 2 buffers) to be shown since we kept scanning out of the old (now unpinned!) buffer. This commit fixes this by adding code to vbox_crtc_page_flip() to tell the hardware to scanout from the new fb_offset.

The root cause is the DT for this system has no phandle properties when booted with BootX. of_populate_phandle_cache() does not handle the case of no phandles correctly. The problem is roundup_pow_of_two() for 0 is undefined. The implementation subtracts 1 underflowing and then things are in the weeds.

2018-09-11drm/i915/overlay: Allocate physical registers from stolenChris Wilson
Given that we are now reasonably confident in our ability to detect and reserve the stolen memory (physical memory reserved for graphics by the BIOS) for ourselves on most machines, we can put it to use. In this case, we need a page to hold the overlay registers. On an i915g running MythTv, H Buus noticed that commit 6a2c4232ece145d8b5a8f95f767bd6d0d2d2f2bb Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Nov 4 04:51:40 2014 -0800 drm/i915: Make the physical object coherent with GTT introduced stuttering into his video playback. After discarding the likely suspect of it being the physical cursor updates, we were left with the use of the phys object for the overlay. And lo, if we completely avoid using the phys object (allocated just once on module load!) by switching to stolen memory, the stuttering goes away. For lack of a better explanation, claim victory and kill two birds with one stone.
