commit 16b036af upstream. If the image size would ever read as 0, pci_get_rom_size() could keep processing the same image over and over again. Exit the loop if we ever read a length of zero. This fixes a soft lockup on boot when the radeon driver calls pci_get_rom_size() on an AMD Radeon R7 250X PCIe discrete graphics card.

commit 6d1cff2a upstream. We hit use after free on dereferncing pointer to task_smack struct in smk_of_task() called from smack_task_to_inode(). task_security() macro uses task_cred_xxx() to get pointer to the task_smack. task_cred_xxx() could be used only for non-pointer members of task's credentials. It cannot be used for pointer members since what they point to may disapper after dropping RCU read lock. Mainly task_security() used this way: smk_of_task(task_security(p)) Intead of this introduce function smk_of_task_struct() which takes task_struct as argument and returns pointer to smk_known struct and do this under RCU read lock. Bogus task_security() macro is not used anymore, so remove it.

commit 5efd2ea8 upstream. the following error pops up during "testusb -a -t 10" | musb-hdrc musb-hdrc.1.auto: dma_pool_free buffer-128, f134e000/be842000 (bad dma) hcd_buffer_create() creates a few buffers, the smallest has 32 bytes of size. ARCH_KMALLOC_MINALIGN is set to 64 bytes. This combo results in hcd_buffer_alloc() returning memory which is 32 bytes aligned and it might by identified by buffer_offset() as another buffer. This means the buffer which is on a 32 byte boundary will not get freed, instead it tries to free another buffer with the error message. This patch fixes the issue by creating the smallest DMA buffer with the size of ARCH_KMALLOC_MINALIGN (or 32 in case ARCH_KMALLOC_MINALIGN is smaller). This might be 32, 64 or even 128 bytes. The next three pools will have the size 128, 512 and 2048. In case the smallest pool is 128 bytes then we have only three pools instead of four (and zero the first entry in the array). The last pool size is always 2048 bytes which is the assumed PAGE_SIZE / 2 of 4096. I doubt it makes sense to continue using PAGE_SIZE / 2 where we would end up with 8KiB buffer in case we have 16KiB pages. Instead I think it makes sense to have a common size(s) and extend them if there is need to. There is a BUILD_BUG_ON() now in case someone has a minalign of more than 128 bytes. Signed-off-by:

commit 145b3fe5 upstream. Some implementations of modprobe fail to load the driver for a PCI device automatically because the "interface" part of the modalias from the kernel is lowercase, and the modalias from file2alias is uppercase. The "interface" is the low-order byte of the Class Code, defined in PCI r3.0, Appendix D. Most interface types defined in the spec do not use alpha characters, so they won't be affected. For example, 00h, 01h, 10h, 20h, etc. are unaffected. Print the "interface" byte of the Class Code in uppercase hex, as we already do for the Vendor ID, Device ID, Class, etc. Commit 89ec3dcf ("PCI: Generate uppercase hex for modalias interface class") fixed only half of the problem. Some udev implementations rely on the uevent file and not the modalias file.

commit 06cf35f9 upstream. Some AMD CS553x devices have read-only BARs because of a firmware or hardware defect. There's a workaround in quirk_cs5536_vsa(), but it no longer works after 36e81648 ("PCI: Restore detection of read-only BARs"). Prior to 36e81648, we filled in res->start; afterwards we leave it zeroed out. The quirk only updated the size, so the driver tried to use a region starting at zero, which didn't work. Expand quirk_cs5536_vsa() to read the base addresses from the BARs and hard-code the sizes. On Nix's system BAR 2's read-only value is 0x6200. Prior to 36e81648, we interpret that as a 512-byte BAR based on the lowest-order bit set. Per datasheet sec 5.6.1, that BAR (MFGPT) requires only 64 bytes; use that to avoid clearing any address bits if a platform uses only 64-byte alignment. [bhelgaas: changelog, reduce BAR 2 size to 64] Fixes: 36e81648 ("PCI: Restore detection of read-only BARs") Link: https://bugzilla.kernel.org/show_bug.cgi?id=85991#c4 Link: http://support.amd.com/TechDocs/31506_cs5535_databook.pdf Link: http://support.amd.com/TechDocs/33238G_cs5536_db.pdfReported-and-tested-by:

commit 3fe89b3e upstream. I have constantly stumbled upon "kernel BUG at mm/rmap.c:399!" after upgrading to 3.19 and had no luck with 4.0-rc1 neither. So, after looking into new logic introduced by commit 7a3ef208 ("mm: prevent endless growth of anon_vma hierarchy"), I found chances are that unlink_anon_vmas() is called without incrementing dst->anon_vma->degree in anon_vma_clone() due to allocation failure. If dst->anon_vma is not NULL in error path, its degree will be incorrectly decremented in unlink_anon_vmas() and eventually underflow when exiting as a result of another call to unlink_anon_vmas(). That's how "kernel BUG at mm/rmap.c:399!" is triggered for me. This patch fixes the underflow by dropping dst->anon_vma when allocation fails. It's safe to do so regardless of original value of dst->anon_vma because dst->anon_vma doesn't have valid meaning if anon_vma_clone() fails. Besides, callers don't care dst->anon_vma in such case neither. Also suggested by Michal Hocko, we can clean up vma_adjust() a bit as anon_vma_clone() now does the work.

commit 91edd096 upstream. Commit db31c55a (net: clamp ->msg_namelen instead of returning an error) introduced the clamping of msg_namelen when the unsigned value was larger than sizeof(struct sockaddr_storage). This caused a msg_namelen of -1 to be valid. The native code was subsequently fixed by commit dbb490b9 (net: socket: error on a negative msg_namelen). In addition, the native code sets msg_namelen to 0 when msg_name is NULL. This was done in commit (6a2a2b3a net:socket: set msg_namelen to 0 if msg_name is passed as NULL in msghdr struct from userland) and subsequently updated by 08adb7da (fold verify_iovec() into copy_msghdr_from_user()).

commit 283ee148 upstream. According to a report from Yuxuan Shui, nilfs2 in kernel 3.19 got stuck during recovery at mount time. The code path that caused the deadlock was as follows: nilfs_fill_super() load_nilfs() nilfs_salvage_orphan_logs() * Do roll-forwarding, attach segment constructor for recovery, and kick it. nilfs_segctor_thread() nilfs_segctor_thread_construct() * A lock is held with nilfs_transaction_lock() nilfs_segctor_do_construct() nilfs_segctor_drop_written_files() iput() iput_final() write_inode_now() writeback_single_inode() __writeback_single_inode() do_writepages() nilfs_writepage() nilfs_construct_dsync_segment() nilfs_transaction_lock() --> deadlock This can happen if commit 7ef3ff2f ("nilfs2: fix deadlock of segment constructor over I_SYNC flag") is applied and roll-forward recovery was performed at mount time. The roll-forward recovery can happen if datasync write is done and the file system crashes immediately after that. For instance, we can reproduce the issue with the following steps: < nilfs2 is mounted on /nilfs (device: /dev/sdb1) > # dd if=/dev/zero of=/nilfs/test bs=4k count=1 && sync # dd if=/dev/zero of=/nilfs/test conv=notrunc oflag=dsync bs=4k count=1 && reboot -nfh < the system will immediately reboot > # mount -t nilfs2 /dev/sdb1 /nilfs The deadlock occurs because iput() can run segment constructor through writeback_single_inode() if MS_ACTIVE flag is not set on sb->s_flags. The above commit changed segment constructor so that it calls iput() asynchronously for inodes with i_nlink == 0, but that change was imperfect. This fixes the another deadlock by deferring iput() in segment constructor even for the case that mount is not finished, that is, for the case that MS_ACTIVE flag is not set. Signed-off-by:

However, there is a slight difference between numbers in TX Level and TX FIFO size. So, by specification the FIFO size would be in a range 2-256 bytes. From TX Level prospective it means we can set threshold in the range 0-(FIFO size - 1) bytes. Hence there are currently two issues: a) FIFO size 2 bytes is actually skipped since TX Level is 1 bit and could be either 0 or 1 byte; b) FIFO size is incorrectly decreased by 1 which already done by meaning of TX Level register. This patch fixes it eventually right. Fixes: d297933c (spi: dw: Fix detecting FIFO depth) Reviewed-by:

commit 29183a70 upstream. Additional validation of adjtimex freq values to avoid potential multiplication overflows were added in commit 5e5aeb43 (time: adjtimex: Validate the ADJ_FREQUENCY values) Unfortunately the patch used LONG_MAX/MIN instead of LLONG_MAX/MIN, which was fine on 64-bit systems, but being much smaller on 32-bit systems caused false positives resulting in most direct frequency adjustments to fail w/ EINVAL. ntpd only does direct frequency adjustments at startup, so the issue was not as easily observed there, but other time sync applications like ptpd and chrony were more effected by the bug. See bugs: https://bugzilla.kernel.org/show_bug.cgi?id=92481 https://bugzilla.redhat.com/show_bug.cgi?id=1188074 This patch changes the checks to use LLONG_MAX for clarity, and additionally the checks are disabled on 32-bit systems since LLONG_MAX/PPM_SCALE is always larger then the 32-bit long freq value, so multiplication overflows aren't possible there.

commit e512d56c upstream. git commit 37f81fa1 "n_tty: do O_ONLCR translation as a single write" surfaced a bug in the 3215 device driver. In combination this broke tab expansion for tty ouput. The cause is an asymmetry in the behaviour of tty3215_ops->write vs tty3215_ops->put_char. The put_char function scans for '\t' but the write function does not. As the driver has logic for the '\t' expansion remove XTABS from c_oflag of the initial termios as well. Reported-by:

commit 6424babf upstream. During file system stress testing on 3.10 and 3.12 based kernels, the umount command occasionally hung in fsnotify_unmount_inodes in the section of code: spin_lock(&inode->i_lock); if (inode->i_state & (I_FREEING|I_WILL_FREE|I_NEW)) { spin_unlock(&inode->i_lock); continue; } As this section of code holds the global inode_sb_list_lock, eventually the system hangs trying to acquire the lock. Multiple crash dumps showed: The inode->i_state == 0x60 and i_count == 0 and i_sb_list would point back at itself. As this is not the value of list upon entry to the function, the kernel never exits the loop. To help narrow down problem, the call to list_del_init in inode_sb_list_del was changed to list_del. This poisons the pointers in the i_sb_list and causes a kernel to panic if it transverse a freed inode. Subsequent stress testing paniced in fsnotify_unmount_inodes at the bottom of the list_for_each_entry_safe loop showing next_i had become free. We believe the root cause of the problem is that next_i is being freed during the window of time that the list_for_each_entry_safe loop temporarily releases inode_sb_list_lock to call fsnotify and fsnotify_inode_delete. The code in fsnotify_unmount_inodes attempts to prevent the freeing of inode and next_i by calling __iget. However, the code doesn't do the __iget call on next_i if i_count == 0 or if i_state & (I_FREEING | I_WILL_FREE) The patch addresses this issue by advancing next_i in the above two cases until we either find a next_i which we can __iget or we reach the end of the list. This makes the handling of next_i more closely match the handling of the variable "inode." The time to reproduce the hang is highly variable (from hours to days.) We ran the stress test on a 3.10 kernel with the proposed patch for a week without failure. During list_for_each_entry_safe, next_i is becoming free causing the loop to never terminate. Advance next_i in those cases where __iget is not done. Signed-off-by:

commit 6a2a2b3a upstream. Linux manpage for recvmsg and sendmsg calls does not explicitly mention setting msg_namelen to 0 when msg_name passed set as NULL. When developers don't set msg_namelen member in msghdr, it might contain garbage value which will fail the validation check and sendmsg and recvmsg calls from kernel will return EINVAL. This will break old binaries and any code for which there is no access to source code. To fix this, we set msg_namelen to 0 when msg_name is passed as NULL from userland. Signed-off-by:

commit be8e8908 upstream. The hardware range code values and list of valid ranges for the AI subdevice is incorrect for several supported boards. The hardware range code values for all boards except PCI-DAS4020/12 is determined by calling `ai_range_bits_6xxx()` based on the maximum voltage of the range and whether it is bipolar or unipolar, however it only returns the correct hardware range code for the PCI-DAS60xx boards. For PCI-DAS6402/16 (and /12) it returns the wrong code for the unipolar ranges. For PCI-DAS64/Mx/16 it returns the wrong code for all the ranges and the comedi range table is incorrect. Change `ai_range_bits_6xxx()` to use a look-up table pointed to by new member `ai_range_codes` of `struct pcidas64_board` to map the comedi range table indices to the hardware range codes. Use a new comedi range table for the PCI-DAS64/Mx/16 boards (and the commented out variants). Signed-off-by:
