commit bb2d990b6fefaf99b2832a7a588234e7986ebe15 Author: Greg Kroah-Hartman Date: Tue Nov 27 16:09:42 2018 +0100 Linux 4.9.141 commit c3ec4e5bda441079e8b5b02bd9e5edd544132123 Author: Ilya Dryomov Date: Thu Nov 8 15:55:37 2018 +0100 libceph: fall back to sendmsg for slab pages commit 7e241f647dc7087a0401418a187f3f5b527cc690 upstream. skb_can_coalesce() allows coalescing neighboring slab objects into a single frag: return page == skb_frag_page(frag) && off == frag->page_offset + skb_frag_size(frag); ceph_tcp_sendpage() can be handed slab pages. One example of this is XFS: it passes down sector sized slab objects for its metadata I/O. If the kernel client is co-located on the OSD node, the skb may go through loopback and pop on the receive side with the exact same set of frags. When tcp_recvmsg() attempts to copy out such a frag, hardened usercopy complains because the size exceeds the object's allocated size: usercopy: kernel memory exposure attempt detected from ffff9ba917f20a00 (kmalloc-512) (1024 bytes) Although skb_can_coalesce() could be taught to return false if the resulting frag would cross a slab object boundary, we already have a fallback for non-refcounted pages. Utilize it for slab pages too.

When a UHID_CREATE command is written to the uhid char device, a copy_from_user() is done from a user pointer embedded in the command. When the address limit is KERNEL_DS, e.g. as is the case during sys_sendfile(), this can read from kernel memory. Alternatively, information can be leaked from a setuid binary that is tricked to write to the file descriptor. Therefore, forbid UHID_CREATE in these cases. No other commands in uhid_char_write() are affected by this bug and UHID_CREATE is marked as "obsolete", so apply the restriction to UHID_CREATE only rather than to uhid_char_write() entirely. Thanks to Dmitry Vyukov for adding uhid definitions to syzkaller and to Jann Horn for commit 9da3f2b740544 ("x86/fault: BUG() when uaccess helpers fault on kernel addresses"), allowing this bug to be found.

Many HP AMD based laptops contain an SMB0001 device like this: Device (SMBD) { Name (_HID, "SMB0001") // _HID: Hardware ID Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { IO (Decode16, 0x0B20, // Range Minimum 0x0B20, // Range Maximum 0x20, // Alignment 0x20, // Length ) IRQ (Level, ActiveLow, Shared, ) {7} }) } The legacy style IRQ resource here causes acpi_dev_get_irqresource() to be called with legacy=true and this message to show in dmesg: ACPI: IRQ 7 override to edge, high This causes issues when later on the AMD0030 GPIO device gets enumerated: Device (GPIO) { Name (_HID, "AMDI0030") // _HID: Hardware ID Name (_CID, "AMDI0030") // _CID: Compatible ID Name (_UID, Zero) // _UID: Unique ID Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings { Name (RBUF, ResourceTemplate () { Interrupt (ResourceConsumer, Level, ActiveLow, Shared, ,, ) { 0x00000007, } Memory32Fixed (ReadWrite, 0xFED81500, // Address Base 0x00000400, // Address Length ) }) Return (RBUF) /* \_SB_.GPIO._CRS.RBUF */ } } Now acpi_dev_get_irqresource() gets called with legacy=false, but because of the earlier override of the trigger-type acpi_register_gsi() returns -EBUSY (because we try to register the same interrupt with a different trigger-type) and we end up setting IORESOURCE_DISABLED in the flags. The setting of IORESOURCE_DISABLED causes platform_get_irq() to call acpi_irq_get() which is not implemented on x86 and returns -EINVAL. resulting in the following in dmesg: amd_gpio AMDI0030:00: Failed to get gpio IRQ: -22 amd_gpio: probe of AMDI0030:00 failed with error -22 The SMB0001 is a "virtual" device in the sense that the only way the OS interacts with it is through calling a couple of methods to do SMBus transfers. As such it is weird that it has IO and IRQ resources at all, because the driver for it is not expected to ever access the hardware directly. The Linux driver for the SMB0001 device directly binds to the acpi_device through the acpi_bus, so we do not need to instantiate a platform_device for this ACPI device. This commit adds the SMB0001 HID to the forbidden_id_list, avoiding the instantiating of a platform_device for it. Not instantiating a platform_device means we will no longer call acpi_dev_get_irqresource() for the legacy IRQ resource fixing the probe of the AMDI0030 device failing.

The problem is that if there is an IRQ which triggers immediately, then we need "info->uio_dev" but it's not set yet.

Patch ad608fbcf166 changed how events were subscribed to address an issue elsewhere. As a side effect of that change, the "add" callback was called before the event subscription was added to the list of subscribed events, causing the first event queued by the add callback (and possibly other events arriving soon afterwards) to be lost. Fix this by adding the subscription to the list before calling the "add" callback, and clean up afterwards if that fails.

[BUG] fstrim on some btrfs only trims the unallocated space, not trimming any space in existing block groups. [CAUSE] Before fstrim_range passed to btrfs_trim_fs(), it gets truncated to range [0, super->total_bytes). So later btrfs_trim_fs() will only be able to trim block groups in range [0, super->total_bytes). While for btrfs, any bytenr aligned to sectorsize is valid, since btrfs uses its logical address space, there is nothing limiting the location where we put block groups. For filesystem with frequent balance, it's quite easy to relocate all block groups and bytenr of block groups will start beyond super->total_bytes. In that case, btrfs will not trim existing block groups.

Function btrfs_trim_fs() doesn't handle errors in a consistent way. If error happens when trimming existing block groups, it will skip the remaining blocks and continue to trim unallocated space for each device. The return value will only reflect the final error from device trimming. This patch will fix such behavior by: 1) Recording the last error from block group or device trimming The return value will also reflect the last error during trimming. Make developer more aware of the problem. 2) Continuing trimming if possible If we failed to trim one block group or device, we could still try the next block group or device. 3) Report number of failures during block group and device trimming It would be less noisy, but still gives user a brief summary of what's going wrong. Such behavior can avoid confusion for cases like failure to trim the first block group and then only unallocated space is trimmed.

This conflicts with Linux RTC driver (rtc-cmos.c) who fails to reserve those ports for itself preventing RTC from functioning. In addition the WDAT table seems not to be fully functional because it does not reset the system when the watchdog times out. On this system iTCO_wdt works just fine so we simply prefer to use it instead of WDAT. This makes RTC working again and also results working watchdog via iTCO_wdt.

That function should release the buffers attached to the gfs2_bitmap objects (bi_bh), but the call to gfs2_rgrp_brelse for doing that is missing. When gfs2_releasepage later runs across these buffers which are still referenced, it refuses to free them. This causes the pages the buffers are attached to to remain referenced as well. With enough mount/unmount cycles, the system will eventually run out of memory. Fix this by adding the missing call to gfs2_rgrp_brelse in gfs2_clear_rgrpd. (Also fix a gfs2_rgrp_relse -> gfs2_rgrp_brelse typo in a comment.)

The preferred way to achieve this is for userspace to delete all the IPs on the interface. But qeth is expected to also tolerate a configuration where that is not the case, by skipping the IP registration when in sniffer mode. Since commit 5f78e29ceebf ("qeth: optimize IP handling in rx_mode callback") reworked the IP registration logic in the L3 subdriver, this no longer works. When the qeth device is set online, qeth_l3_recover_ip() now unconditionally registers all unicast addresses from our internal IP table. While we could fix this particular problem by skipping qeth_l3_recover_ip() on a sniffer device, the more future-proof change is to skip the IP address registration at the lowest level. This way we a) catch any future code path that attempts to register an IP address without considering the sniffer scenario, and b) continue to build up our internal IP table, so that if sniffer mode is switched off later we can operate just like normal.

This bug is randomly triggered by xfstests generic/027, but here is a faster reproducer: truncate -s 50M fs.iso mkfs.hfsplus fs.iso mount fs.iso /mnt i=100 while [ $i -le 150 ]; do touch /mnt/$i &>/dev/null ((++i)) done i=100 while [ $i -le 150 ]; do mv /mnt/$i /mnt/$(perl -e "print $i x82") &>/dev/null ((++i)) done umount /mnt fsck.hfsplus -n fs.iso The bug is triggered whenever hfs_brec_update_parent() needs to split the root node. The height of the btree is not increased, which leaves the new node orphaned and its records lost.

Fernández Date: Tue Oct 30 15:06:07 2018 -0700 hfs: prevent btree data loss on root split [ Upstream commit d057c036672f33d43a5f7344acbb08cf3a8a0c09 ] This bug is triggered whenever hfs_brec_update_parent() needs to split the root node. The height of the btree is not increased, which leaves the new node orphaned and its records lost. It is not possible for this to happen on a valid hfs filesystem because the index nodes have fixed length keys. For reasons I ignore, the hfs module does have support for a number of hfsplus features. A corrupt btree header may report variable length keys and trigger this bug, so it's better to fix it.

Plumb them through. Note that reiserfs_for_each_xattr() is only used by reiserfs_delete_xattrs() and reiserfs_chown_xattrs(). The result of reiserfs_delete_xattrs() is discarded anyway, the only difference there is whether a warning is printed to dmesg. The result of reiserfs_chown_xattrs() does matter because it can block chowning of the file to which the xattrs belong; but either way, the resulting state can have misaligned ownership, so my patch doesn't improve things greatly. Credit for making me look at this code goes to Al Viro, who pointed out that the ->actor calling convention is suboptimal and should be changed.

However, before this check, pointer smb_file_target is derived from dst_file->private and dereferenced in the call to tlink_tcon, hence there is a potential null pointer deference. Fix this by assigning smb_file_target and target_tcon after the null pointer sanity checks.
