commit 956421fb upstream. 'ret_from_fork' checks TIF_IA32 to determine whether 'pt_regs' and the related state make sense for 'ret_from_sys_call'. This is entirely the wrong check. TS_COMPAT would make a little more sense, but there's really no point in keeping this optimization at all. This fixes a return to the wrong user CS if we came from int 0x80 in a 64-bit task.

commit 6d65261a upstream. eCryptfs can't be aware of what to expect when after passing an arbitrary ioctl command through to the lower filesystem. The ioctl command may trigger an action in the lower filesystem that is incompatible with eCryptfs. One specific example is when one attempts to use the Btrfs clone ioctl command when the source file is in the Btrfs filesystem that eCryptfs is mounted on top of and the destination fd is from a new file created in the eCryptfs mount. The ioctl syscall incorrectly returns success because the command is passed down to Btrfs which thinks that it was able to do the clone operation. However, the result is an empty eCryptfs file. This patch allows the trim, {g,s}etflags, and {g,s}etversion ioctl commands through and then copies up the inode metadata from the lower inode to the eCryptfs inode to catch any changes made to the lower inode's metadata. Those five ioctl commands are mostly common across all filesystems but the whitelist may need to be further pruned in the future. https://bugzilla.kernel.org/show_bug.cgi?id=93691 https://launchpad.net/bugs/1305335Signed-off-by:

commit b3cffac0 upstream. Currently the guest exit trace event saves the VCPU pointer to the structure, and the guest PC is retrieved by dereferencing it when the event is printed rather than directly from the trace record. This isn't safe as the printing may occur long afterwards, after the PC has changed and potentially after the VCPU has been freed. Usually this results in the same (wrong) PC being printed for multiple trace events. It also isn't portable as userland has no way to access the VCPU data structure when interpreting the trace record itself. Lets save the actual PC in the structure so that the correct value is accessible later. Fixes: 669e846e ("KVM/MIPS32: MIPS arch specific APIs for KVM") Signed-off-by:

commit abe46b89 upstream. Reading of analog input channels by the `INSN_READ` comedi instruction is broken for all except channel 0. `pci171x_ai_insn_read()` calls `pci171x_ai_read_sample()` with the wrong value for the third parameter. It is supposed to be the current index in a channel list (which is always of length 1 in this case, so the index should be 0), but instead it is passing the actual channel number. `pci171x_ai_read_sample()` checks the channel number encoded in the raw sample value read from the hardware matches the channel number stored in the specified index of the previously set up channel list and returns `-ENODATA` if it doesn't match. Since the index should always be 0 in this case, the match will fail unless the channel number is also 0. Fix it by passing 0 as the channel index. Note that when the bug first appeared, it was `pci171x_ai_dropout()` that was called with the wrong parameter value. `pci171x_ai_dropout()` got replaced with `pci171x_ai_read_sample()` in commit 7fd2dae2 ("staging: comedi: adv_pci1710: introduce pci171x_ai_read_sample()").

commit 9c1c98a3 upstream. The current minstrel_ht rate control behavior is somewhat optimistic in trying to find optimum TX rate. While this is usually fine for normal Data frames, there are cases where a more conservative set of retry parameters would be beneficial to make the connection more robust. EAPOL frames are critical to the authentication and especially the EAPOL-Key message 4/4 (the last message in the 4-way handshake) is important to get through to the AP. If that message is lost, the only recovery mechanism in many cases is to reassociate with the AP and start from scratch. This can often be avoided by trying to send the frame with more conservative rate and/or with more link layer retries. In most cases, minstrel_ht is currently using the initial EAPOL-Key frames for probing higher rates and this results in only five link layer transmission attempts (one at high(ish) MCS and four at MCS0). While this works with most APs, it looks like there are some deployed APs that may have issues with the EAPOL frames using HT MCS immediately after association. Similarly, there may be issues in cases where the signal strength or radio environment is not good enough to be able to get frames through even at couple of MCS 0 tries. The best approach for this would likely to be to reduce the TX rate for the last rate (3rd rate parameter in the set) to a low basic rate (say, 6 Mbps on 5 GHz and 2 or 5.5 Mbps on 2.4 GHz), but doing that cleanly requires some more effort. For now, we can start with a simple one-liner that forces the minimum rate to be used for EAPOL frames similarly how the TX rate is selected for the IEEE 802.11 Management frames. This does result in a small extra latency added to the cases where the AP would be able to receive the higher rate, but taken into account how small number of EAPOL frames are used, this is likely to be insignificant. A future optimization in the minstrel_ht design can also allow this patch to be reverted to get back to the more optimized initial TX rate. It should also be noted that many drivers that do not use minstrel as the rate control algorithm are already doing similar workarounds by forcing the lowest TX rate to be used for EAPOL frames.

commit 7ed620bb upstream. While adding support loading kernel and initrd above 4G to grub2 in legacy mode, I was referring to efi_high_alloc(). That will allocate buffer for kernel and then initrd, and initrd will use kernel buffer start as limit. During testing found two buffers will be overlapped when initrd size is very big like 400M. It turns out efi_high_alloc() boundary checking is not right. end - size will be the new start, and should not compare new start with max, we need to make sure end is smaller than max. [ Basically, with the current efi_high_alloc() code it's possible to allocate memory above 'max', because efi_high_alloc() doesn't check that the tail of the allocation is below 'max'. If you have an EFI memory map with a single entry that looks like so, [0xc0000000-0xc0004000] And want to allocate 0x3000 bytes below 0xc0003000 the current code will allocate [0xc0001000-0xc0004000], not [0xc0000000-0xc0003000] like you would expect. - Matt ] Signed-off-by:

commit 1e7e4fb6 upstream. The commit 97374792 ("usb: host: xhci-plat: add support for the Armada 375/38x XHCI controllers") extended the xhci-plat driver to support the Armada 375/38x SoCs, mostly by adding a quirk configuring the MBUS window. However, that quirk was run before the clock the controllers needs has been enabled. This usually worked because the clock was first enabled by the bootloader, and left as such until the driver is probe, where it tries to access the MBUS configuration registers before enabling the clock. Things get messy when EPROBE_DEFER is involved during the probe, since as part of its error path, the driver will rightfully disable the clock. When the driver will be reprobed, it will retry to access the MBUS registers, but this time with the clock disabled, which hangs forever. Fix this by running the quirks after the clock has been enabled by the driver. Signed-off-by:

commit 4ff6f8e6 upstream. This has been broken for a long time: it broke first in 2.6.35, then was almost fixed in 2.6.36 but this one-liner slipped through the cracks. The bug shows up as an infinite loop in Windows 7 (and newer) boot on 32-bit hosts without EPT. Windows uses CMPXCHG8B to write to page tables, which causes a page fault if running without EPT; the emulator is then called from kvm_mmu_page_fault. The loop then happens if the higher 4 bytes are not 0; the common case for this is that the NX bit (bit 63) is 1. Fixes: 6550e1f1 Fixes: 16518d5aReported-by:

commit a0456399 upstream. The "Extended Compat ID OS Feature Descriptor Specification" does not require the (sub)compatible ids to be NUL-terminated, because they are placed in a fixed-size buffer and only unused parts of it should contain NULs. If the buffer is fully utilized, there is no place for NULs. Consequently, the code which uses desc->ext_compat_id never expects the data contained to be NUL terminated. If the compatible id is stored after sub-compatible id, and the compatible id is full length (8 bytes), the (useless) NUL terminator overwrites the first byte of the sub-compatible id. If the sub-compatible id is full length (8 bytes), the (useless) NUL terminator ends up out of the buffer. The situation can happen in the RNDIS function, where the buffer is a part of struct f_rndis_opts. The next member of struct f_rndis_opts is a mutex, so its first byte gets overwritten. The said byte is a part of a mutex'es member which contains the information on whether the muext is locked or not. This can lead to a deadlock, because, in a configfs-composed gadget when a function is linked into a configuration with config_usb_cfg_link(), usb_get_function() is called, which then calls rndis_alloc(), which tries locking the same mutex and (wrongly) finds it already locked. This patch eliminates NUL terminating of the (sub)compatible id. Fixes: da424314: "usb: gadget: configfs: OS Extended Compatibility descriptors support" Reported-by:

commit 96e5d312 upstream. In the wrapper the IRQ disable should be done by writing 1's to the IRQ*_CLR register. Existing code is broken because it instead writes zeros to IRQ*_SET register. Fix this by adding functions dwc3_omap_write_irqmisc_clr() and dwc3_omap_write_irq0_clr() which do the right thing. Fixes: 72246da4 ("usb: Introduce DesignWare USB3 DRD Driver") Signed-off-by:

commit 03305e53 upstream. Since commit c8231a9a ("iio: mxs-lradc: compute temperature from channel 8 and 9") with the removal of adc channel 9 there is no 1-1 mapping in the channel spec. All hwmon channel values above 9 are accessible via there index minus one. So add a hidden iio channel 9 to fix this issue. Signed-off-by:

commit 19e353f2 upstream. The intention is obviously to sign-extend a 12 bit quantity. But because of C's promotion rules, the assignment is equivalent to "val16 &= 0xfff;". Use the proper API for this. Signed-off-by:

commit 89bb35e2 upstream. Using the touchscreen while running buffered capture results in the buffer reporting lots of wrong values, often just zeros. This is because we push readings to the buffer every time a touchscreen interrupt arrives, including when the buffer's own conversions have not yet finished. So let's only push to the buffer when its conversions are ready. Signed-off-by:
