[PATCH 1/2] of/fdt: Allow architectures to override CONFIG_CMDLINE logic

by Paul Burton

The CONFIG_CMDLINE-related logic in early_init_dt_scan_chosen() falls back to copying CONFIG_CMDLINE into boot_command_line/data if the DT has a /chosen node but that node has no bootargs property or a bootargs property of length zero. This is problematic for the MIPS architecture because we support concatenating arguments from either the DT or the bootloader with those from CONFIG_CMDLINE, but the behaviour of early_init_dt_scan_chosen() gives us no way of knowing whether boot_command_line contains arguments from DT or already contains CONFIG_CMDLINE. This can lead to us concatenating CONFIG_CMDLINE with itself, duplicating command line arguments which can be problematic (eg. for earlycon which will attempt to register the same console twice & warn about it). Move the CONFIG_CMDLINE-related logic to a weak function that architectures can provide their own version of, such that we continue to use the existing logic for architectures where it's suitable but also allow MIPS to override this behaviour such that the architecture code knows when CONFIG_CMDLINE is used.

ovl: hash non-dir by lower inode for fsnotify

by Mark Salyzyn

(cherry pick from commit 764baba80168ad3adafb521d2ab483ccbc49e344) Commit 31747eda41ef ("ovl: hash directory inodes for fsnotify") fixed an issue of inotify watch on directory that stops getting events after dropping dentry caches. A similar issue exists for non-dir non-upper files, for example: $ mkdir -p lower upper work merged $ touch lower/foo $ mount -t overlay -o lowerdir=lower,workdir=work,upperdir=upper none merged $ inotifywait merged/foo & $ echo 2 > /proc/sys/vm/drop_caches $ cat merged/foo inotifywait doesn't get the OPEN event, because ovl_lookup() called from 'cat' allocates a new overlay inode and does not reuse the watched inode. Fix this by hashing non-dir overlay inodes by lower real inode in the following cases that were not hashed before this change: - A non-upper overlay mount - A lower non-hardlink when index=off A helper ovl_hash_bylower() was added to put all the logic and documentation about which real inode an overlay inode is hashed by into one place. The issue dates back to initial version of overlayfs, but this patch depends on ovl_inode code that was introduced in kernel v4.13.

[PATCH] keys: Fix the use of the C++ keyword "private" in uapi/linux/keyctl.h

by David Howells

The keyctl_dh_params struct in uapi/linux/keyctl.h contains the symbol "private" which means that the header file will cause compilation failure if #included in to a C++ program. Further, the patch that added the same struct to the keyutils package named the symbol "priv", not "private". The previous attempt to fix this (commit 8a2336e549d3) did so by simply renaming the kernel's copy of the field to dh_private, but this then breaks existing userspace and as such has been reverted (commit 8c0f9f5b309d). [And note, to those who think that wrapping the struct in extern "C" {} will work: it won't; that only changes how symbol names are presented to the assembler and linker.]. Instead, insert an anonymous union around the "private" member and add a second member in there with the name "priv" to match the one in the keyutils package. The "private" member is then wrapped in !__cplusplus cpp-conditionals to hide it from C++.

[PATCH] platform-msi: Free descriptors in platform_msi_domain_free()

by Miquel Raynal

Since the addition of platform MSI support, there were two helpers supposed to allocate/free IRQs for a device: platform_msi_domain_alloc_irqs() platform_msi_domain_free_irqs() In these helpers, IRQ descriptors are allocated in the "alloc" routine while they are freed in the "free" one. Later, two other helpers have been added to handle IRQ domains on top of MSI domains: platform_msi_domain_alloc() platform_msi_domain_free() Seen from the outside, the logic is pretty close with the former helpers and people used it with the same logic as before: a platform_msi_domain_alloc() call should be balanced with a platform_msi_domain_free() call. While this is probably what was intended to do, the platform_msi_domain_free() does not remove/free the IRQ descriptor(s) created/inserted in platform_msi_domain_alloc(). One effect of such situation is that removing a module that requested an IRQ will let one orphaned IRQ descriptor (with an allocated MSI entry) in the device descriptors list. Next time the module will be inserted back, one will observe that the allocation will happen twice in the MSI domain, one time for the remaining descriptor, one time for the new one. It also has the side effect to quickly overshoot the maximum number of allocated MSI and then prevent any module requesting an interrupt in the same domain to be inserted anymore. This situation has been met with loops of insertion/removal of the mvpp2.ko module (requesting 15 MSIs each time).

Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place. The Clear Linux container is building with NO_CLANG=1, the problem preventing its use when building for python3 has been identified and the next builds will build in ClearLinux with both gcc and clang.

[STABLE PATCH] slub: make ->cpu_partial unsigned int

by zhong jiang

From: Alexey Dobriyan <adobriyan(a)gmail.com> /* * cpu_partial determined the maximum number of objects * kept in the per cpu partial lists of a processor. */ Can't be negative. I hit a real issue that it will result in a large number of memory leak. Because Freeing slabs are in interrupt context. So it can trigger this issue. put_cpu_partial can be interrupted more than once. due to a union struct of lru and pobjects in struct page, when other core handles page->lru list, for eaxmple, remove_partial in freeing slab code flow, It will result in pobjects being a negative value(0xdead0000). Therefore, a large number of slabs will be added to per_cpu partial list. I had posted the issue to community before. The detailed issue description is as follows. Link: https://www.spinics.net/lists/kernel/msg2870979.html After applying the patch, The issue is fixed. So the patch is a effective bugfix. It should go into stable.

[PATCH] mtd: rawnand: marvell: check for RDY bits after enabling the IRQ

by Daniel Mack

At least on PXA3xx platforms, enabling RDY interrupts in the NDCR register will only cause the IRQ to latch when the RDY lanes are changing, and not in case they are already asserted. This means that if the controller finished the command in flight before marvell_nfc_wait_op() is called, that function will wait for a change in the bit that can't ever happen as it is already set. To mitigate this race, check for the RDY bits after the IRQ was enabled, and only sleep on the condition if the controller isn't ready yet. This fixes a bug that was observed with a NAND chip that holds a UBIFS parition on which file system stress tests were executed. When marvell_nfc_wait_op() reports an error, UBI/UBIFS will eventually mount the filesystem read-only, reporting lots of warnings along the way.

[PATCH AUTOSEL 4.9 01/57] crypto: skcipher - Fix -Wstringop-truncation warnings

by Sasha Levin

[PATCH v2] rseq/selftests: fix parametrized test with -fpie

by Mathieu Desnoyers

On x86-64, the parametrized selftest code for rseq crashes with a segmentation fault when compiled with -fpie. This happens when the param_test binary is loaded at an address beyond 32-bit on x86-64. The issue is caused by use of a 32-bit register to hold the address of the loop counter variable. Fix this by using a 64-bit register to calculate the address of the loop counter variables as an offset from rip.

[PATCH] MIPS: VDSO: Always map near top of user memory

by Paul Burton

When using the legacy mmap layout, for example triggered using ulimit -s unlimited, get_unmapped_area() fills memory from bottom to top starting from a fairly low address near TASK_UNMAPPED_BASE. This placement is suboptimal if the user application wishes to allocate large amounts of heap memory using the brk syscall. With the VDSO being located low in the user's virtual address space, the amount of space available for access using brk is limited much more than it was prior to the introduction of the VDSO. For example: # ulimit -s unlimited; cat /proc/self/maps 00400000-004ec000 r-xp 00000000 08:00 71436 /usr/bin/coreutils 004fc000-004fd000 rwxp 000ec000 08:00 71436 /usr/bin/coreutils 004fd000-0050f000 rwxp 00000000 00:00 0 00cc3000-00ce4000 rwxp 00000000 00:00 0 [heap] 2ab96000-2ab98000 r--p 00000000 00:00 0 [vvar] 2ab98000-2ab99000 r-xp 00000000 00:00 0 [vdso] 2ab99000-2ab9d000 rwxp 00000000 00:00 0 ... Resolve this by adjusting STACK_TOP to reserve space for the VDSO & providing an address hint to get_unmapped_area() causing it to use this space even when using the legacy mmap layout. We reserve enough space for the VDSO, plus 1MB or 8MB for 32 bit & 64 bit systems respectively within which we randomize the VDSO base address. Previously this randomization was taken care of by the mmap base address randomization performed by arch_mmap_rnd(). The 1MB & 8MB sizes are somewhat arbitrary but chosen such that we have some randomization without taking up too much of the user's virtual address space, which is often in short supply for 32 bit systems. With this the VDSO is always mapped at a high address, leaving lots of space for statically linked programs to make use of brk: # ulimit -s unlimited; cat /proc/self/maps 00400000-004ec000 r-xp 00000000 08:00 71436 /usr/bin/coreutils 004fc000-004fd000 rwxp 000ec000 08:00 71436 /usr/bin/coreutils 004fd000-0050f000 rwxp 00000000 00:00 0 00c28000-00c49000 rwxp 00000000 00:00 0 [heap] ... 7f67c000-7f69d000 rwxp 00000000 00:00 0 [stack] 7f7fc000-7f7fd000 rwxp 00000000 00:00 0 7fcf1000-7fcf3000 r--p 00000000 00:00 0 [vvar] 7fcf3000-7fcf4000 r-xp 00000000 00:00 0 [vdso] Signed-off-by: Paul Burton <paul.burton(a)mips.com> Reported-by: Huacai Chen <chenhc(a)lemote.com> Fixes: ebb5e78cc634 ("MIPS: Initial implementation of a VDSO") Cc: Huacai Chen <chenhc(a)lemote.com> Cc: linux-mips(a)linux-mips.org Cc: stable(a)vger.kernel.org # v4.4+ --- Huacai, could you test if this fixes your problem?

On a powerpc 8xx, 'btc' fails as follows: Entering kdb (current=0x(ptrval), pid 282) due to Keyboard Entry kdb> btc btc: cpu status: Currently on cpu 0 Available cpus: 0 kdb_getarea: Bad address 0x0 when booting the kernel with 'debug_boot_weak_hash', it fails as well Entering kdb (current=0xba99ad80, pid 284) due to Keyboard Entry kdb> btc btc: cpu status: Currently on cpu 0 Available cpus: 0 kdb_getarea: Bad address 0xba99ad80 On other platforms, Oopses have been observed too, see https://github.com/linuxppc/linux/issues/139 This is due to btc calling 'btt' with %p pointer as an argument. This patch replaces %p by %px to get the real pointer value as expected by 'btt' Fixes: ad67b74d2469 ("printk: hash addresses printed with %p") Cc: <stable(a)vger.kernel.org> Reviewed-by: Daniel Thompson <daniel.thompson(a)linaro.org> Signed-off-by: Christophe Leroy <christophe.leroy(a)c-s.fr> --- v2: Added fixes: and Daniel's reviewed-by: in commit's log.

[PATCH 3.18.y 0/2] HID: sony: backport DualShock 4 device ids

by Roderick Colenbrander

Hi, We would like to request inclusion of updated DualShock 4 device ids for hid-sony in Linux 3.18. Existing devices on older kernels already support the original DualShock 4, but not recent hardware revisions. A similar backport was submitted for 4.4/4.9. Kernels newer than 4.12 already include these patches. The patches were cherry-picked from upstream and modified to apply cleanly and compile.

[PATCH 1/1] bcache: add separate workqueue for journal_write to avoid deadlock

by Coly Li

From: guoju <fangguoju(a)gmail.com> After write SSD completed, bcache schedules journal_write work to system_wq, which is a public workqueue in system, without WQ_MEM_RECLAIM flag. system_wq is also a bound wq, and there may be no idle kworker on current processor. Creating a new kworker may unfortunately need to reclaim memory first, by shrinking cache and slab used by vfs, which depends on bcache device. That's a deadlock. This patch create a new workqueue for journal_write with WQ_MEM_RECLAIM flag. It's rescuer thread will work to avoid the deadlock.

[PATCH 2/3] pinctrl: mcp23s08: fix irq and irqchip setup order

by Marco Felsch

Since 'commit 02e389e63e35 ("pinctrl: mcp23s08: fix irq setup order")' the irq request isn't the last devm_* allocation. Without a deeper look at the irq and testing this isn't a good solution. Since this driver relies on the devm mechanism, requesting a interrupt should be the last thing to avoid memory corruptions during unbinding. 'Commit 02e389e63e35 ("pinctrl: mcp23s08: fix irq setup order")' fixed the order for the interrupt-controller use case only. The mcp23s08_irq_setup() must be split into two to fix it for the interrupt-controller use case and to register the irq at last. So the irq will be freed first during unbind.

[PATCH stable] tick/nohz: Prevent bogus softirq pending warning

by Thomas Gleixner

Commit 0a0e0829f990 ("nohz: Fix missing tick reprogram when interrupting an inline softirq") got backported to stable trees and now causes the NOHZ softirq pending warning to trigger. It's not an upstream issue as the NOHZ update logic has been changed there. The problem is when a softirq disabled section gets interrupted and on return from interrupt the tick/nohz state is evaluated, which then can observe pending soft interrupts. These soft interrupts are legitimately pending because they cannot be processed as long as soft interrupts are disabled and the interrupted code will correctly process them when soft interrupts are reenabled. Add a check for softirqs disabled to the pending check to prevent the warning.

[PATCH 02/10] MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3

by Huacai Chen

For multi-node Loongson-3 (NUMA configuration), r4k_blast_scache() can only flush Node-0's scache. So we add r4k_blast_scache_node() by using (CAC_BASE | (node_id << NODE_ADDRSPACE_SHIFT)) instead of CKSEG0 as the start address.

[PATCH v3] block: fix deadline elevator drain for zoned block devices

by Damien Le Moal

When the deadline scheduler is used with a zoned block device, writes to a zone will be dispatched one at a time. This causes the warning message: deadline: forced dispatching is broken (nr_sorted=X), please report this to be displayed when switching to another elevator with the legacy I/O path while write requests to a zone are being retained in the scheduler queue. Prevent this message from being displayed when executing elv_drain_elevator() for a zoned block device. __blk_drain_queue() will loop until all writes are dispatched and completed, resulting in the desired elevator queue drain without extensive modifications to the deadline code itself to handle forced-dispatch calls.

Backport request HID: sony: update DualShock 4 device ids

by Roderick.Colenbrander＠sony.com

Hi, We would like to request inclusion of 2 patches adding new DualShock 4 device ids to hid-sony. Existing devices on older kernels already support the original DualShock 4, but not recent new revisions. We would like to get these patches included into linux-stable 3.18, 4.4 and 4.9. Kernels newer than 4.12 already include these patches. HID: sony: Support DS4 dongle commit de66a1a04c25f2560a8dca7a95e2a150b0d5e17e upstream HID: sony: Update device ids commit cf1015d65d7c8a5504a4c03afb60fb86bff0f032 upstream Thanks, Roderick Colenbrander Signed-off-by: Roderick Colenbrander <roderick.colenbrander(a)sony.com>

[iw_cxgb4 linux-4.14.y] iw_cxgb4: only allow 1 flush on user qps

[PULL 2/2] virtio/s390: fix race in ccw_io_helper()

by Cornelia Huck

From: Halil Pasic <pasic(a)linux.ibm.com> While ccw_io_helper() seems like intended to be exclusive in a sense that it is supposed to facilitate I/O for at most one thread at any given time, there is actually nothing ensuring that threads won't pile up at vcdev->wait_q. If they do, all threads get woken up and see the status that belongs to some other request than their own. This can lead to bugs. For an example see: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1788432 This race normally does not cause any problems. The operations provided by struct virtio_config_ops are usually invoked in a well defined sequence, normally don't fail, and are normally used quite infrequent too. Yet, if some of the these operations are directly triggered via sysfs attributes, like in the case described by the referenced bug, userspace is given an opportunity to force races by increasing the frequency of the given operations. Let us fix the problem by ensuring, that for each device, we finish processing the previous request before starting with a new one.

[PATCH] fbdev/omapfb: fix omapfb_memory_read infoleak

by Tomi Valkeinen

OMAPFB_MEMORY_READ ioctl reads pixels from the LCD's memory and copies them to a userspace buffer. The code has two issues: - The user provided width and height could be large enough to overflow the calculations - The copy_to_user() can copy uninitialized memory to the userspace, which might contain sensitive kernel information. Fix these by limiting the width & height parameters, and only copying the amount of data that we actually received from the LCD.
