2017-08-24Input: ALPS - fix two-finger scroll breakage in right side on ALPS touchpadMasaki Ota
Fixed the issue that two finger scroll does not work correctly on V8 protocol. The cause is that V8 protocol X-coordinate decode is wrong at SS4 PLUS device. I added SS4 PLUS X decode definition. Mote notes: the problem manifests itself by the commit e7348396c6d5 ("Input: ALPS - fix V8+ protocol handling (73 03 28)"), where a fix for the V8+ protocol was applied. Although the culprit must have been present beforehand, the two-finger scroll worked casually even with the wrongly reported values by some reason. It got broken by the commit above just because it changed x_max value, and this made libinput correctly figuring the MT events. Since the X coord is reported as falsely doubled, the events on the right-half side go outside the boundary, thus they are no longer handled. This resulted as a broken two-finger scroll. One finger event is decoded differently, and it didn't suffer from this problem. The problem was only about MT events. --tiwai Fixes: e7348396c6d5 ("Input: ALPS - fix V8+ protocol handling (73 03 28)") Signed-off-by: Masaki Ota <masaki.ota@jp.alps.com> Tested-by: Takashi Iwai <tiwai@suse.de> Tested-by: Paul Donohue <linux-kernel@PaulSD.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2017-08-24qlge: avoid memcpy buffer overflowArnd Bergmann
gcc-8.0.0 (snapshot) points out that we copy a variable-length string into a fixed length field using memcpy() with the destination length, and that ends up copying whatever follows the string: inlined from 'ql_core_dump' at drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:1106:2: drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:708:2: error: 'memcpy' reading 15 bytes from a region of size 14 [-Werror=stringop-overflow=] memcpy(seg_hdr->description, desc, (sizeof(seg_hdr->description)) - 1); Changing it to use strncpy() will instead zero-pad the destination, which seems to be the right thing to do here. The bug is probably harmless, but it seems like a good idea to address it in stable kernels as well, if only for the purpose of building with gcc-8 without warnings.

2017-08-24pty: Repair TIOCGPTPEEREric W. Biederman
The implementation of TIOCGPTPEER has two issues. When /dev/ptmx (as opposed to /dev/pts/ptmx) is opened the wrong vfsmount is passed to dentry_open. Which results in the kernel displaying the wrong pathname for the peer. The second is simply by caching the vfsmount and dentry of the peer it leaves them open, in a way they were not previously Which because of the inreased reference counts can cause unnecessary behaviour differences resulting in regressions. To fix these move the ioctl into tty_io.c at a generic level allowing the ioctl to have access to the struct file on which the ioctl is being called. This allows the path of the slave to be derived when opening the slave through TIOCGPTPEER instead of requiring the path to the slave be cached. Thus removing the need for caching the path. A new function devpts_ptmx_path is factored out of devpts_acquire and used to implement a function devpts_mntget. The new function devpts_mntget takes a filp to perform the lookup on and fsi so that it can confirm that the superblock that is found by devpts_ptmx_path is the proper superblock. v2: Lots of fixes to make the code actually work v3: Suggestions by Linus - Removed the unnecessary initialization of filp in ptm_open_peer - Simplified devpts_ptmx_path as gotos are no longer required [ This is the fix for the issue that was reverted in commit 143c97cc6529, but this time without breaking 'pbuilder' due to increased reference counts - Linus ] Fixes: 54ebbfb16034 ("tty: add TIOCGPTPEER ioctl") Reported-by: Christian Brauner <christian.brauner@canonical.com> Reported-and-tested-by: Stefan Lippers-Hollmann <s.l-h@gmx.de> Signed-off-by: "Eric W.

2017-08-24IB/core: Avoid accessing non-allocated memory when inferring port typeNoa Osherovich
Commit 44c58487d51a ("IB/core: Define 'ib' and 'roce' rdma_ah_attr types") introduced the concept of type in ah_attr: * During ib_register_device, each port is checked for its type which is stored in ib_device's port_immutable array. * During uverbs' modify_qp, the type is inferred using the port number in ib_uverbs_qp_dest struct (address vector) by accessing the relevant port_immutable array and the type is passed on to providers. IB spec (version 1.3) enforces a valid port value only in Reset to Init. During Init to RTR, the address vector must be valid but port number is not mentioned as a field in the address vector, so its value is not validated, which leads to accesses to a non-allocated memory when inferring the port type. Save the real port number in ib_qp during modify to Init (when the comp_mask indicates that the port number is valid) and use this value to infer the port type. Avoid copying the address vector fields if the matching bit is not set in the attr_mask. Address vector can't be modified before the port, so no valid flow is affected.

2017-08-23Revert "pty: fix the cached path of the pty slave file descriptor in the master"Linus Torvalds
This reverts commit c8c03f1858331e85d397bacccd34ef409aae993c. It turns out that while fixing the ptmx file descriptor to have the correct 'struct path' to the associated slave pty is a really good thing, it breaks some user space tools for a very annoying reason. The problem is that /dev/ptmx and its associated slave pty (/dev/pts/X) are on different mounts. That was what caused us to have the wrong path in the first place (we would mix up the vfsmount of the 'ptmx' node, with the dentry of the pty slave node), but it also means that now while we use the right vfsmount, having the pty master open also keeps the pts mount busy. And it turn sout that that makes 'pbuilder' very unhappy, as noted by Stefan Lippers-Hollmann: "This patch introduces a regression for me when using pbuilder 0.228.7[2] (a helper to build Debian packages in a chroot and to create and update its chroots) when trying to umount /dev/ptmx (inside the chroot) on Debian/ unstable (full log and pbuilder configuration file[3] attached). [...] Setting up build-essential (12.3) ... Processing triggers for libc-bin (2.24-15) ... I: unmounting dev/ptmx filesystem W: Could not unmount dev/ptmx: umount: /var/cache/pbuilder/build/1340/dev/ptmx: target is busy (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1).)" apparently pbuilder tries to unmount the /dev/pts filesystem while still holding at least one master node open, which is arguably not very nice, but we don't break user space even when fixing other bugs. So this commit has to be reverted. I'll try to figure out a way to avoid caching the path to the slave pty in the master pty. The only thing that actually wants that slave pty path is the "TIOCGPTPEER" ioctl, and I think we could just recreate the path at that time.

2017-08-23drm/i915/gvt: Fix the kernel null pointer errorfred gao
once error happens in shadow_indirect_ctx function, the variable wa_ctx->indirect_ctx.obj is not initialized but accessed, so the kernel null point panic occurs.

2017-08-22fsl/man: Inherit parent device and of_nodeFlorian Fainelli
Junote Cai reported that he was not able to get a DSA setup involving the Freescale DPAA/FMAN driver to work and narrowed it down to of_find_net_device_by_node(). This function requires the network device's device reference to be correctly set which is the case here, though we have lost any device_node association there. The problem is that dpaa_eth_add_device() allocates a "dpaa-ethernet" platform device, and later on dpaa_eth_probe() is called but SET_NETDEV_DEV() won't be propagating &pdev->dev.of_node properly. Fix this by inherenting both the parent device and the of_node when dpaa_eth_add_device() creates the platform device.

2017-08-22net: phy: Deal with unbound PHY driver in phy_attached_print()Florian Fainelli
Priit reported that stmmac was crashing with the trace below. This is because phy_attached_print() is called too early right after the PHY device has been found, but before it has a driver attached, since that is only done in phy_probe() which occurs later. Fix this by dealing with a possibly NULL phydev->drv point since that can happen here, but could also happen if we voluntarily did an unbind of the PHY device with the PHY driver. sun7i-dwmac 1c50000.ethernet: PTP uses main clock sun7i-dwmac 1c50000.ethernet: no reset control found sun7i-dwmac 1c50000.ethernet: no regulator found sun7i-dwmac 1c50000.ethernet: Ring mode enabled sun7i-dwmac 1c50000.ethernet: DMA HW capability register supported sun7i-dwmac 1c50000.ethernet: Normal descriptors libphy: stmmac: probed Unable to handle kernel NULL pointer dereference at virtual address 00000048 pgd = c0004000 [00000048] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.13.0-rc6-00318-g0065bd7fa384 #1 Hardware name: Allwinner sun7i (A20) Family task: ee868000 task.stack: ee85c000 PC is at phy_attached_print+0x1c/0x8c LR is at stmmac_mdio_register+0x12c/0x200 pc : [<c04510ac>] lr : [<c045e6b4>] psr: 60000013 sp : ee85ddc8 ip : 00000000 fp : c07dfb5c r10: ee981210 r9 : 00000001 r8 : eea73000 r7 : eeaa6dd0 r6 : eeb49800 r5 : 00000000 r4 : 00000000 r3 : 00000000 r2 : 00000000 r1 : 00000000 r0 : eeb49800 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 4000406a DAC: 00000051 Process swapper/0 (pid: 1, stack limit = 0xee85c210) Stack: (0xee85ddc8 to 0xee85e000) ddc0: 00000000 00000002 eeb49400 eea72000 00000000 eeb49400 dde0: c045e6b4 00000000 ffffffff eeab0810 00000000 c08051f8 ee9292c0 c016d480 de00: eea725c0 eea73000 eea72000 00000001 eea726c0 c0457d0c 00000040 00000020 de20: 00000000 c045b850 00000001 00000000 ee981200 eeab0810 eeaa6ed0 ee981210 de40: 00000000 c094a4a0 00000000 c0465180 eeaa7550 f08d0000 c9ffb90c 00000032 de60: fffffffa 00000032 ee981210 ffffffed c0a46620 fffffdfb c0a46620 c03f7be8 de80: ee981210 c0a9a388 00000000 00000000 c0a46620 c03f63e0 ee981210 c0a46620 dea0: ee981244 00000000 00000007 000000c6 c094a4a0 c03f6534 00000000 c0a46620 dec0: c03f6490 c03f49ec ee828a58 ee9217b4 c0a46620 eeaa4b00 c0a43230 c03f59fc dee0: c08051f8 c094a49c c0a46620 c0a46620 00000000 c091c668 c093783c c03f6dfc df00: ffffe000 00000000 c091c668 c010177c eefe0938 eefe0935 c085e200 000000c6 df20: 00000005 c0136bc8 60000013 c080b3a4 00000006 00000006 c07ce7b4 00000000 df40: c07d7ddc c07cef28 eefe0938 eefe093e c0a0b2f0 c0a641c0 c0a641c0 c0a641c0 df60: c0937834 00000007 000000c6 c094a4a0 00000000 c0900d88 00000006 00000006 df80: 00000000 c09005a8 00000000 c060ecf4 00000000 00000000 00000000 00000000 dfa0: 00000000 c060ecfc 00000000 c0107738 00000000 00000000 00000000 00000000 dfc0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 dfe0: 00000000 00000000 00000000 00000000 00000013 00000000 ffdeffff ffffffff [<c04510ac>] (phy_attached_print) from [<c045e6b4>] (stmmac_mdio_register+0x12c/0x200) [<c045e6b4>] (stmmac_mdio_register) from [<c045b850>] (stmmac_dvr_probe+0x850/0x96c) [<c045b850>] (stmmac_dvr_probe) from [<c0465180>] (sun7i_gmac_probe+0x120/0x180) [<c0465180>] (sun7i_gmac_probe) from [<c03f7be8>] (platform_drv_probe+0x50/0xac) [<c03f7be8>] (platform_drv_probe) from [<c03f63e0>] (driver_probe_device+0x234/0x2e4) [<c03f63e0>] (driver_probe_device) from [<c03f6534>] (__driver_attach+0xa4/0xa8) [<c03f6534>] (__driver_attach) from [<c03f49ec>] (bus_for_each_dev+0x4c/0x9c) [<c03f49ec>] (bus_for_each_dev) from [<c03f59fc>] (bus_add_driver+0x190/0x214) [<c03f59fc>] (bus_add_driver) from [<c03f6dfc>] (driver_register+0x78/0xf4) [<c03f6dfc>] (driver_register) from [<c010177c>] (do_one_initcall+0x44/0x168) [<c010177c>] (do_one_initcall) from [<c0900d88>] (kernel_init_freeable+0x144/0x1d0) [<c0900d88>] (kernel_init_freeable) from [<c060ecfc>] (kernel_init+0x8/0x110) [<c060ecfc>] (kernel_init) from [<c0107738>] (ret_from_fork+0x14/0x3c) Code: e59021c8 e59d401c e590302c e3540000 (e5922048) ---[ end trace 39ae87c7923562d0 ]--- Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b Tested-By: Priit Laes <plaes@plaes.org> Fixes: fbca164776e4 ("net: stmmac: Use the right logging function in stmmac_mdio_register") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2017-08-22ACPI: device property: Fix node lookup in acpi_graph_get_child_prop_value()Sakari Ailus
acpi_graph_get_child_prop_value() is intended to find a child node with a certain property value pair. The check if (!fwnode_property_read_u32(fwnode, prop_name, &nr)) continue; is faulty: fwnode_property_read_u32() returns zero on success, not on failure, leading to comparing values only if the searched property was not found. Moreover, the check is made against the parent device node instead of the child one as it should be.

2017-08-22ACPICA: Fix acpi_evaluate_object_typed()Rafael J. Wysocki
Commit 2d2a954375a0 (ACPICA: Update two error messages to emit control method name) causes acpi_evaluate_object_typed() to fail if its pathname argument is NULL, but some callers of that function in the kernel, particularly acpi_nondev_subnode_data_ok(), pass NULL as pathname to it and expect it to work. For this reason, make acpi_evaluate_object_typed() check if its pathname argument is NULL and fall back to using the pathname of its handle argument if that is the case.

2017-08-22RDMA/uverbs: Initialize cq_context appropriatelyBharat Potnuri
Initializing cq_context with ev_queue in create_cq(), leads to NULL pointer dereference in ib_uverbs_comp_handler(), if application doesnot use completion channel. This patch fixes the cq_context initialization.

2017-08-22drm: Release driver tracking before making the object available againChris Wilson
This is the same bug as we fixed in commit f6cd7daecff5 ("drm: Release driver references to handle before making it available again"), but now the exposure is via the PRIME lookup tables. If we remove the object/handle from the PRIME lut, then a new request for the same object/fd will generate a new handle, thus for a short window that object is known to userspace by two different handles. Fix this by releasing the driver tracking before PRIME.
