Merge tag 'fixes-for-v4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.6-rc5 No more major fixes left. Out of the 6 fixes we have here, 4 are on dwc3. The most important is the memory leak fix in dwc3/debugfs.c. We also have a fix for PHY handling in suspend/resume and a fix for dwc3-omap's error handling. Suspend/resume also had the potential to trigger a NULL pointer dereference on dwc3; that's also fixed now. Our good ol' ffs function gets a use-after-free fix while the generic composite.c layer has a robustness fix by making sure reserved fields of a possible SSP device capability descriptor is cleared to 0.

When doing a make allmodconfig, I hit the following compile error: In file included from builtin-check.c:32:0: elf.h:22:18: fatal error: gelf.h: No such file or directory compilation terminated. ... Digging into it, it appears that the $(shell ..) command in the Makefile does not give the proper result when it fails to find -lelf, and continues to compile objtool. Instead, use the "try-run" makefile macro to perform the test. This gives a proper result for both cases. Signed-off-by:

Allowing userptr bo which are basicly a list of page from some vma (so either anonymous page or file backed page) would lead to serious corruption of kernel structures and counters (because we overwrite the page->mapping field when mapping buffer). This will already block if the buffer was populated before anyone does try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm vm fault handler. So to be safe just add a check to verify_access() callback. Reviewed-by:

With the joys of things running concurrently, there's always a chance that the port we get passed in drm_dp_payload_send_msg() isn't actually valid anymore. Because of this, we need to make sure we validate the reference to the port before we use it otherwise we risk running into various race conditions. For instance, on the Dell MST monitor I have here for testing, hotplugging it enough times causes us to kernel panic: [drm:intel_mst_enable_dp] 1 [drm:drm_dp_update_payload_part2] payload 0 1 [drm:intel_get_hpd_pins] hotplug event received, stat 0x00200000, dig 0x10101011, pins 0x00000020 [drm:intel_hpd_irq_handler] digital hpd port B - short [drm:intel_dp_hpd_pulse] got hpd irq on port B - short [drm:intel_dp_check_mst_status] got esi 00 10 00 [drm:drm_dp_update_payload_part2] payload 1 1 general protection fault: 0000 [#1] SMP … Call Trace: [<ffffffffa012b632>] drm_dp_update_payload_part2+0xc2/0x130 [drm_kms_helper] [<ffffffffa032ef08>] intel_mst_enable_dp+0xf8/0x180 [i915] [<ffffffffa0310dbd>] haswell_crtc_enable+0x3ed/0x8c0 [i915] [<ffffffffa030c84d>] intel_atomic_commit+0x5ad/0x1590 [i915] [<ffffffffa01db877>] ? drm_atomic_set_crtc_for_connector+0x57/0xe0 [drm] [<ffffffffa01dc4e7>] drm_atomic_commit+0x37/0x60 [drm] [<ffffffffa0130a3a>] drm_atomic_helper_set_config+0x7a/0xb0 [drm_kms_helper] [<ffffffffa01cc482>] drm_mode_set_config_internal+0x62/0x100 [drm] [<ffffffffa01d02ad>] drm_mode_setcrtc+0x3cd/0x4e0 [drm] [<ffffffffa01c18e3>] drm_ioctl+0x143/0x510 [drm] [<ffffffffa01cfee0>] ? drm_mode_setplane+0x1b0/0x1b0 [drm] [<ffffffff810f79a7>] ? hrtimer_start_range_ns+0x1b7/0x3a0 [<ffffffff81212962>] do_vfs_ioctl+0x92/0x570 [<ffffffff81590852>] ? __sys_recvmsg+0x42/0x80 [<ffffffff81212eb9>] SyS_ioctl+0x79/0x90 [<ffffffff816b4e32>] entry_SYSCALL_64_fastpath+0x1a/0xa4 RIP [<ffffffffa012b026>] drm_dp_payload_send_msg+0x146/0x1f0 [drm_kms_helper] Which occurs because of the hotplug event shown in the log, which ends up causing DRM's dp helpers to drop the port we're updating the payload on and panic.

With commit 8bc2a407 ("rtc: ds1307: add support for the DT property 'wakeup-source'") we lost the ability for rtc irq functionality for devices that are actually hooked on a real IRQ line and have capability to wakeup as well. This is not an expected behavior. So, instead of just not requesting IRQ, skip the IRQ requirement only if interrupts are not defined for the device.

When using masked actions the ipv6_proto field of an action to set IPv6 fields may be zero rather than the prevailing protocol which will result in skipping checksum recalculation. This patch resolves the problem by relying on the protocol in the flow key rather than that in the set field action. Fixes: 83d2b9ba ("net: openvswitch: Support masked set actions.")

atl2 includes NETIF_F_SG in hw_features even though it has no support for non-linear skbs. This bug was originally harmless since the driver does not claim to implement checksum offload and that used to be a requirement for SG. Now that SG and checksum offload are independent features, if you explicitly enable SG *and* use one of the rare protocols that can use SG without checkusm offload, this potentially leaks sensitive information (before you notice that it just isn't working). Therefore this obscure bug has been designated CVE-2016-2117. Reported-by:

Commit 2a078705 ("irqchip/mips-gic: Use gic_vpes instead of NR_CPUS") & commit 78930f09 ("irqchip/mips-gic: Clear percpu_masks correctly when mapping") both introduce code which accesses gic_vpes entries in the pcpu_masks array. However, this array has length NR_CPUS. If NR_CPUS is less than gic_vpes (ie. the kernel supports use of less CPUs than are present in the system) then we overrun the array, clobber some other data & generally die pretty promptly. Most notably this affects uniprocessor kernels running on any multicore or multithreaded Malta with a GIC (ie. the vast majority of real Malta boards). Fix this by only accessing up to min(gic_vpes, NR_CPUS) entries in the pcpu_masks array, preventing the array overrun.

Or Gerlitz says: ==================== Mellaox 40G driver fixes for 4.6-rc With the fix for ARM bug being under the works, these are few other fixes for mlx4 we have ready to go. Eran addressed the problematic/wrong reporting of dropped packets, Daniel fixed some matters related to PPC EEH's and Jenny's patch makes sure VFs can't change the port's pause settings. ==================== Signed-off-by:

Count SW packet drops per RX ring instead of a global counter. This will allow monitoring the number of rx drops per ring. In addition, SW rx_dropped counter was overwritten by HW rx_dropped counter, sum both of them instead to show the accurate value.

Currently changing global pause settings is done via SET_PORT command with input modifier GENERAL. This command is allowed for each VF since MTU setting is done via the same command. Change the above to the following scheme: before passing the request to the FW, the PF will check whether it was issued by a slave. If yes, don't change global pause and warn, otherwise change to the requested value and store for further reference. Signed-off-by:
