commit ebabcf17 upstream. GCC7 is a bit too eager to generate suboptimal __multi3 calls (128bit multiply with 128bit result) for MIPS64r6 builds, even in code which doesn't explicitly use 128bit types, such as the following: unsigned long func(unsigned long a, unsigned long b) { return a > (~0UL) / b; } Which GCC rearanges to: return (unsigned __int128)a * (unsigned __int128)b > 0xffffffffffffffff; Therefore implement __multi3, but only for MIPS64r6 with GCC7 as under normal circumstances we wouldn't expect any calls to __multi3 to be generated from kernel code.

[ Upstream commit c76f97c9 ] Some sockopt handling functions were calculating the length of the buffer to be written to userspace and then calculating it again when actually writing the buffer, which could lead to some write not using an up-to-date length. This patch updates such places to just make use of the len variable. Also, replace some sizeof(type) to sizeof(var). Signed-off-by:

[ Upstream commit cf2acf66 ] When cleaning up after a partially successful gntdev_mmap(), unmap the successfully mapped grant pages otherwise Xen will kill the domain if in debug mode (Attempt to implicitly unmap a granted PTE) or Linux will kill the process and emit "BUG: Bad page map in process" if Xen is in release mode. This is only needed when use_ptemod is true because gntdev_put_map() will unmap grant pages itself when use_ptemod is false. Signed-off-by:

[ Upstream commit 78f30004 ] In bnxt_vf_ndo_prep (which is called by bnxt_get_vf_config ndo), there is a check for "Invalid VF id". Currently, the check is done against max_vfs. However, the user doesn't always create max_vfs. So, the check should be against the created number of VFs. The number of bnxt_vf_info structures that are allocated in bnxt_alloc_vf_resources routine is the "number of requested VFs". So, if an "invalid VF id" falls between the requested number of VFs and the max_vfs, the driver will be dereferencing an invalid pointer. Fixes: c0c050c5 ("bnxt_en: New Broadcom ethernet driver.")

In ipoib_start_xmit, both gets NULL when calling ipoib_neigh_get. Two calls to neigh_add_path are made. One thread takes the spin-lock and calls ipoib_neigh_alloc which creates the neigh structure, then (after the __path_find) the neigh is added to the path's neigh link list. When the second thread enters the critical section it also calls ipoib_neigh_alloc but in this case it gets the already allocated ipoib_neigh structure, which is already linked to the path's neigh link list and adds it again to the list. Which beside of triggering the list, it creates a loop in the linked list. This loop leads to endless loop inside path_rec_completion. Solution: Check list_empty(&neigh->list) before adding to the list.

[ Upstream commit 5a371cf8 ] ibmr.device is being set only after ib_alloc_mr() is successfully complete. Therefore, in case imlx4_mr_enable() returns with error, the error flow unwinder calls to mlx4_free_priv_pages(), which uses ibmr.device. Such usage causes to NULL dereference oops and to fix it, the IB device should be set in the mr struct earlier stage (e.g. prior to calling mlx4_free_priv_pages()).

[ Upstream commit 8a9bd4f8 ] We store per path and per device configuration data to identify the path or device correctly. The per path configuration data might get mixed up if the original request gets into error recovery and is started with a random path mask. This would lead to a wrong identification of a path in case of a CUIR event for example. Fix by copying the path mask from the original request to the error recovery request in case it is a path verification request. Signed-off-by:

[ Upstream commit f7084059 ] While in recovery process of PCI error (called EEH on PowerPC arch), another PCI transaction could be corrupted causing a situation of nested PCI errors. Also, this scenario could be reproduced with error injection mechanisms (for debug purposes). We observe that in case of nested PCI errors, bnx2x might attempt to initialize its shmem and cause a kernel crash due to bad addresses read from MCP. Multiple different stack traces were observed depending on the point the second PCI error happens. This patch avoids the crashes by: * failing PCI recovery in case of nested errors (since multiple PCI errors in a row are not expected to lead to a functional adapter anyway), and by, * preventing access to adapter FW when MCP is failed (we mark it as failed when shmem cannot get initialized properly).

[ Upstream commit bbc25bee ] Current MIPS64r6 toolchains aren't able to generate efficient DMULU/DMUHU based code for the C implementation of umul_ppmm(), which performs an unsigned 64 x 64 bit multiply and returns the upper and lower 64-bit halves of the 128-bit result. Instead it widens the 64-bit inputs to 128-bits and emits a __multi3 intrinsic call to perform a 128 x 128 multiply. This is both inefficient, and it results in a link error since we don't include __multi3 in MIPS linux. For example commit 90a53e44 ("cfg80211: implement regdb signature checking") merged in v4.15-rc1 recently broke the 64r6_defconfig and 64r6el_defconfig builds by indirectly selecting MPILIB. The same build errors can be reproduced on older kernels by enabling e.g. CRYPTO_RSA: lib/mpi/generic_mpih-mul1.o: In function `mpihelp_mul_1': lib/mpi/generic_mpih-mul1.c:50: undefined reference to `__multi3' lib/mpi/generic_mpih-mul2.o: In function `mpihelp_addmul_1': lib/mpi/generic_mpih-mul2.c:49: undefined reference to `__multi3' lib/mpi/generic_mpih-mul3.o: In function `mpihelp_submul_1': lib/mpi/generic_mpih-mul3.c:49: undefined reference to `__multi3' lib/mpi/mpih-div.o In function `mpihelp_divrem': lib/mpi/mpih-div.c:205: undefined reference to `__multi3' lib/mpi/mpih-div.c:142: undefined reference to `__multi3' Therefore add an efficient MIPS64r6 implementation of umul_ppmm() using inline assembly and the DMULU/DMUHU instructions, to prevent __multi3 calls being emitted.

[ Upstream commit 588753f1 ] One example of when an ICMPv6 packet is required to be looped back is when a host acts as both a Multicast Listener and a Multicast Router. A Multicast Router will listen on address ff02::16 for MLDv2 messages. Currently, MLDv2 messages originating from a Multicast Listener running on the same host as the Multicast Router are not being delivered to the Multicast Router. This is due to dst.input being assigned the default value of dst_discard. This results in the packet being looped back but discarded before being delivered to the Multicast Router. This patch sets dst.input to ip6_input to ensure a looped back packet is delivered to the Multicast Router. Signed-off-by:

[ Upstream commit fdf2e821 ] When erased subpages are read then the BCH decoder returns STATUS_ERASED if they are all empty, or STATUS_UNCORRECTABLE if there are bitflips. When there are bitflips, we have to set these bits again to show the upper layers a completely erased page. When a bitflip happens in the exact byte where the bad block marker is, then this byte is swapped with another byte in block_mark_swapping(). The correction code then detects a bitflip in another subpage and no longer corrects the bitflip where it really happens. Correct this behaviour by calling block_mark_swapping() after the bitflips have been corrected. In our case UBIFS failed with this bug because it expects erased pages to be really empty: UBIFS error (pid 187): ubifs_scan: corrupt empty space at LEB 36:118735 UBIFS error (pid 187): ubifs_scanned_corruption: corruption at LEB 36:118735 UBIFS error (pid 187): ubifs_scanned_corruption: first 8192 bytes from LEB 36:118735 UBIFS error (pid 187): ubifs_scan: LEB 36 scanning failed UBIFS error (pid 187): do_commit: commit failed, error -117 Signed-off-by:

commit 48d0c9be upstream. The POSIX specification defines that relative CLOCK_REALTIME timers are not affected by clock modifications. Those timers have to use CLOCK_MONOTONIC to ensure POSIX compliance. The introduction of the additional HRTIMER_MODE_PINNED mode broke this requirement for pinned timers. There is no user space visible impact because user space timers are not using pinned mode, but for consistency reasons this needs to be fixed. Check whether the mode has the HRTIMER_MODE_REL bit set instead of comparing with HRTIMER_MODE_ABS. Signed-off-by:

When commit 4be5a281 ("binder: check for binder_thread allocation failure in binder_poll()") was applied to 4.4-stable and 4.9-stable it was forgotten to release the global binder lock in the new error path. The global binder lock wasn't removed until v4.14, by commit a60b890f ("binder: remove global binder lock"). Fix the new error path to release the lock. Reported-by:

commit 458d876e upstream. We only support vga_switcheroo and runtime pm on PX/HG systems so forcing runpm to 1 doesn't do anything useful anyway. Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so that the cleanup path is correct as well. This mirrors what radeon does as well. v2: rework the patch originally sent by Lukas (Alex) Acked-by:

commit 17aa31f1 upstream. This fixes an issue that a gadget driver (usb_f_fs) is possible to stop rx transactions after the usb-dmac is used because the following functions missed to set/check the "running" flag. - usbhsf_dma_prepare_pop_with_usb_dmac() - usbhsf_dma_pop_done_with_usb_dmac() So, if next transaction uses pio, the usbhsf_prepare_pop() can not start the transaction because the "running" flag is 0.

commit 6cf439e0 upstream. During _ffs_func_bind(), the received descriptors are evaluated to prepare for binding with the gadget in order to allocate endpoints and optionally set up OS descriptors. However, the high- and super-speed descriptors are only parsed based on whether the gadget_is_dualspeed() and gadget_is_superspeed() calls are true, respectively. This is a problem in case a userspace program always provides all of the {full,high,super,OS} descriptors when configuring a function. Then, for example if a gadget device is not capable of SuperSpeed, the call to ffs_do_descs() for the SS descriptors is skipped, resulting in an incorrect offset calculation for the vla_ptr when moving on to the OS descriptors that follow. This causes ffs_do_os_descs() to fail as it is now looking at the SS descriptors' offset within the raw_descs buffer instead. _ffs_func_bind() should evaluate the descriptors unconditionally, so remove the checks for gadget speed.
