2018-01-05ALSA: aloop: Release cable upon open error pathTakashi Iwai1-13/+25
The aloop runtime object and its assignment in the cable are left even when opening a substream fails. This doesn't mean any memory leak, but it still keeps the invalid pointer that may be referred by the another side of the cable spontaneously, which is a potential Oops cause. Clean up the cable assignment and the empty cable upon the error path properly.

2018-01-05ALSA: pcm: Workaround for weird PulseAudio behavior on rewind errorTakashi Iwai1-2/+7
The commit 9027c4639ef1 ("ALSA: pcm: Call ack() whenever appl_ptr is updated") introduced the possible error code returned from the PCM rewind ioctl. Basically the change was for handling the indirect PCM more correctly, but ironically, it caused rather a side-effect: PulseAudio gets pissed off when receiving an error from rewind, throws everything away and stops processing further, resulting in the silence. It's clearly a failure in the application side, so the best would be to fix that bug in PA. OTOH, PA is mostly the only user of the rewind feature, so it's not good to slap the sole customer. This patch tries to mitigate the situation: instead of returning an error, now the rewind ioctl returns zero when the driver can't rewind. It indicates that no rewind was performed, so the behavior is consistent, at least.

2018-01-05ARM: dts: da850-lcdk: Remove leading 0x and 0s from unit addressMathieu Malaterre1-2/+2
Improve the DTS files by removing all the leading "0x" and zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" and Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C For simplicity, two sed expressions were used to solve each warnings separately.

2018-01-05iwlwifi: pcie: fix DMA memory mapping / unmappingEmmanuel Grumbach3-15/+14
22000 devices (previously referenced as A000) can support short transmit queues. This means that we have less DMA descriptors (TFD) for those shorter queues. Previous devices must still have 256 TFDs for each queue even if those 256 TFDs point to fewer buffers. When I introduced support for the short queues for 22000 I broke older devices by assuming that they can also have less TFDs in their queues. This led to several problems: 1) the payload of the commands weren't unmapped properly which caused the SWIOTLB to complain at some point. 2) the hardware could get confused and we get hardware crashes.

2018-01-05ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7Thomas Petazzoni1-2/+8
MPP7 is currently muxed as "gpio", but this function doesn't exist for MPP7, only "gpo" is available. This causes the following error: kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7 pinctrl core: failed to register map default (6): invalid type given kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22 kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22 kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22 So the pinctrl driver is not probed, all device drivers (including the UART driver) do a -EPROBE_DEFER, and therefore the system doesn't really boot (well, it boots, but with no UART, and no devices that require pin-muxing). Back when the Device Tree file for this board was introduced, the definition was already wrong. The pinctrl driver also always described as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11, a hog pin failing to be muxed was turned from a simple warning to a hard error that caused the entire pinctrl driver probe to bail out. This is probably the result of commit 6118714275f0a ("pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()"). This commit fixes the Device Tree to use the proper "gpo" function for MPP7, which fixes the boot of OpenBlocks A7, which was broken since Linux 4.11.

2018-01-05crypto: algapi - fix NULL dereference in crypto_remove_spawns()Eric Biggers1-0/+12
syzkaller triggered a NULL pointer dereference in crypto_remove_spawns() via a program that repeatedly and concurrently requests AEADs "authenc(cmac(des3_ede-asm),pcbc-aes-aesni)" and hashes "cmac(des3_ede)" through AF_ALG, where the hashes are requested as "untested" (CRYPTO_ALG_TESTED is set in ->salg_mask but clear in ->salg_feat; this causes the template to be instantiated for every request). Although AF_ALG users really shouldn't be able to request an "untested" algorithm, the NULL pointer dereference is actually caused by a longstanding race condition where crypto_remove_spawns() can encounter an instance which has had spawn(s) "grabbed" but hasn't yet been registered, resulting in ->cra_users still being NULL. We probably should properly initialize ->cra_users earlier, but that would require updating many templates individually. For now just fix the bug in a simple way that can easily be backported: make crypto_remove_spawns() treat a NULL ->cra_users list as empty.

2018-01-04kernel/acct.c: fix the acct->needcheck check in check_free_space()Oleg Nesterov1-1/+1
As Tsukada explains, the time_is_before_jiffies(acct->needcheck) check is very wrong, we need time_is_after_jiffies() to make sys_acct() work. Ignoring the overflows, the code should "goto out" if needcheck > jiffies, while currently it checks "needcheck < jiffies" and thus in the likely case check_free_space() does nothing until jiffies overflow. In particular this means that sys_acct() is simply broken, acct_on() sets acct->needcheck = jiffies and expects that check_free_space() should set acct->active = 1 after the free-space check, but this won't happen if jiffies increments in between. This was broken by commit 32dc73086015 ("get rid of timer in kern/acct.c") in 2011, then another (correct) commit 795a2f22a8ea ("acct() should honour the limits from the very beginning") made the problem more visible.

The reason is some efi reserved boot ranges is not reported in E820 ram. In my case it is a bgrt buffer: efi: mem00: [Boot Data |RUN| | | | | | | |WB|WT|WC|UC] range=[0x00000000d2c41000-0x00000000d2c85fff] (0MB) Use "add_efi_memmap" can workaround the problem with another fix: http://lkml.kernel.org/r/[email protected] In zero_resv_unavail it would be better to check pfn_valid first before zero the page struct. This fixes the problem and potential other similar problems. Also as Pavel Tatashin suggested checks pfn_valid at the beginning of the section. The range is backed by real memory.

But some of them need to be reserved, for example the bgrt image address in an acpi table, if the image memory is freed then kexec reboot will fail because kexec inherit same acpi table to initialize the driver.

2018-01-05x86/tlb: Drop the _GPL from the cpu_tlbstate exportThomas Gleixner1-1/+1
The recent changes for PTI touch cpu_tlbstate from various tlb_flush inlines. cpu_tlbstate is exported as GPL symbol, so this causes a regression when building out of tree drivers for certain graphics cards. Aside of that the export was wrong since it was introduced as it should have been EXPORT_PER_CPU_SYMBOL_GPL(). Use the correct PER_CPU export and drop the _GPL to restore the previous state which allows users to utilize the cards they payed for. As always I'm really thrilled to make this kind of change to support the #friends (or however the hot hashtag of today is spelled) from that closet sauce graphics corp.

2018-01-05x86/kaslr: Fix the vaddr_end messThomas Gleixner3-24/+22
vaddr_end for KASLR is only documented in the KASLR code itself and is adjusted depending on config options. So it's not surprising that a change of the memory layout causes KASLR to have the wrong vaddr_end. This can map arbitrary stuff into other areas causing hard to understand problems. Remove the whole ifdef magic and define the start of the cpu_entry_area to be the end of the KASLR vaddr range. Add documentation to that effect.

2018-01-04x86/mm: Set MODULES_END to 0xffffffffff000000Andrey Ryabinin2-5/+2
Since f06bdd4001c2 ("x86/mm: Adapt MODULES_END based on fixmap section size") kasan_mem_to_shadow(MODULES_END) could be not aligned to a page boundary. So passing page unaligned address to kasan_populate_zero_shadow() have two possible effects: 1) It may leave one page hole in supposed to be populated area. After commit 21506525fb8d ("x86/kasan/64: Teach KASAN about the cpu_entry_area") that hole happens to be in the shadow covering fixmap area and leads to crash: BUG: unable to handle kernel paging request at fffffbffffe8ee04 RIP: 0010:check_memory_region+0x5c/0x190 Call Trace: <NMI> memcpy+0x1f/0x50 ghes_copy_tofrom_phys+0xab/0x180 ghes_read_estatus+0xfb/0x280 ghes_notify_nmi+0x2b2/0x410 nmi_handle+0x115/0x2c0 default_do_nmi+0x57/0x110 do_nmi+0xf8/0x150 end_repeat_nmi+0x1a/0x1e Note, the crash likely disappeared after commit 92a0f81d8957, which changed kasan_populate_zero_shadow() call the way it was before commit 21506525fb8d. 2) Attempt to load module near MODULES_END will fail, because __vmalloc_node_range() called from kasan_module_alloc() will hit the WARN_ON(!pte_none(*pte)) in the vmap_pte_range() and bail out with error. To fix this we need to make kasan_mem_to_shadow(MODULES_END) page aligned which means that MODULES_END should be 8*PAGE_SIZE aligned. The whole point of commit f06bdd4001c2 was to move MODULES_END down if NR_CPUS is big, so the cpu_entry_area takes a lot of space. But since 92a0f81d8957 ("x86/cpu_entry_area: Move it out of the fixmap") the cpu_entry_area is no longer in fixmap, so we could just set MODULES_END to a fixed 8*PAGE_SIZE aligned address.

Harden CMD_SUBMIT path to handle malicious input that could trigger large memory allocations. Add checks to validate transfer_buffer_length and number_of_packets to protect against bad input requesting for unbounded memory allocations.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into fixes Pull "Allwinner fixes for 4.15" from Chen-Yu Tsai: First, one fix that adds proper regulator references for the EMAC external PHYs on A64 boards. The EMAC bindings were developed for 4.13, but reverted at the last minute. They were finalized and brought back for 4.15. However in the time between, regulator support for the A64 boards was merged. When EMAC device tree changes were reintroduced, this was not taken into account. Second, a patch that adds OF based modalias uevent for RSB slave devices. This has been missing since the introduction of RSB, and recently with PMIC regulator support introduced for the A64, has been seen affecting distributions, which have the all-important PMIC mfd drivers built as modules, which then don't get loaded. Other minor cleanups include final conversion of raw indices to CCU binding macros for sun[4567]i HDMI, cleanup of dummy regulators on the A64 SOPINE, a SD card detection polarity fix for the Orange Pi Zero Plus2, and adding a missing compatible for the PMIC on the TBS A711 tablet. * tag 'sunxi-fixes-for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: ARM: dts: sun8i: a711: Reinstate the PMIC compatible arm64: dts: orange-pi-zero-plus2: fix sdcard detect arm64: allwinner: a64-sopine: Fix to use dcdc1 regulator instead of vcc3v3 ARM: dts: sunxi: Convert to CCU index macros for HDMI controller sunxi-rsb: Include OF based modalias in device uevent arm64: allwinner: a64: add Ethernet PHY regulator for several boards

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes Pull "Renesas ARM Based SoC Fixes for v4.15" from Simon Horman: Vladimir Zapolskiy says: The present change is a bug fix for AVB link iteratively up/down. Steps to reproduce: - start AVB TX stream (Using aplay via MSE), - disconnect+reconnect the eth cable, - after a reconnection the eth connection goes iteratively up/down without user interaction, - this may heal after some seconds or even stay for minutes. As the documentation specifies, the "renesas,no-ether-link" option should be used when a board does not provide a proper AVB_LINK signal. There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS and ULCB starter kits since the AVB_LINK is correctly handled by HW. Choosing to keep or remove the "renesas,no-ether-link" option will have impact on the code flow in the following ways: - keeping this option enabled may lead to unexpected behavior since the RX & TX are enabled/disabled directly from adjust_link function without any HW interrogation, - removing this option, the RX & TX will only be enabled/disabled after HW interrogation. The HW check is made through the LMON pin in PSR register which specifies AVB_LINK signal value (0 - at low level; 1 - at high level). In conclusion, the change is also a safety improvement because it removes the "renesas,no-ether-link" option leading to a proper way of detecting the link state based on HW interrogation and not on software heuristic. Note that DTS files for V3M Starter Kit, Draak and Eagle boards contain the same property, the files are untouched due to unavailable schematics to verify if the fix applies to these boards as well. * tag 'renesas-fixes-for-v4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/horms/renesas: arm64: dts: renesas: ulcb: Remove renesas, no-ether-link property arm64: dts: renesas: salvator-x: Remove renesas, no-ether-link property
2018-01-04Bluetooth: Prevent stack info leak from the EFS element.Ben Seri1-9/+11
In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs, (void *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes).
