commit 37017ac6 upstream. The Broadcom OSB4 IDE Controller (vendor and device IDs: 1166:0211) does not support 64-KB DMA transfers. Whenever a 64-KB DMA transfer is attempted, the transfer fails and messages similar to the following are written to the console log: [ 2431.851125] sr 0:0:0:0: [sr0] Unhandled sense code [ 2431.851139] sr 0:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 2431.851152] sr 0:0:0:0: [sr0] Sense Key : Hardware Error [current] [ 2431.851166] sr 0:0:0:0: [sr0] Add.

The CSB series appears to support 64-KB DMA transfers, as tests on a machine with an SAI2 motherboard containing a Broadcom CSB5 IDE Controller (vendor and device IDs: 1166:0212) showed no problems with 64-KB DMA transfers. This problem was first discovered when attempting to install openSUSE from a DVD on a machine with an STL2 motherboard. Using the pata_serverworks module, older releases of openSUSE will not install at all due to the timeouts. Releases of openSUSE prior to 11.3 can be installed by disabling the pata_serverworks module using the brokenmodules boot parameter, which causes the serverworks module to be used instead. Recent releases of openSUSE (12.2 and later) include better error recovery and will install, though very slowly. On all openSUSE releases, the problem can be recreated on a machine containing a Broadcom OSB4 IDE Controller by mounting an install DVD and running a command similar to the following: find /mnt -type f -print | xargs cat > /dev/null The patch below corrects the problem. Similar to the other ATA drivers that do not support 64-KB DMA transfers, the patch changes the ata_port_operations qc_prep vector to point to a routine that breaks any 64-KB segment into two 32-KB segments and changes the scsi_host_template sg_tablesize element to reduce by half the number of scatter/gather elements allowed. These two changes affect only the OSB4. Signed-off-by:

commit 2aca5b86 upstream. The flag RPC_CLNT_CREATE_NO_RETRANS_TIMEOUT was intended introduced in order to allow NFSv4 clients to disable resend timeouts. Since those cause the RPC layer to break the connection, they mess up the duplicate reply caches that remain indexed on the port number in NFSv4.. This patch includes the code that was missing in the original to set the appropriate flag in struct rpc_clnt, when the caller of rpc_create() sets RPC_CLNT_CREATE_NO_RETRANS_TIMEOUT.

commit a743419f upstream. When aborting a connection to preserve source ports, don't wake the task in xs_error_report. This allows tasks with RPC_TASK_SOFTCONN to succeed if the connection needs to be re-established since it preserves the task's status instead of setting it to the status of the aborting kernel_connect(). This may also avoid a potential conflict on the socket's lock. Signed-off-by:

commit e300180f upstream. The radeon driver uses placement range restrictions for several reasons, in particular to make sure BOs in VRAM can be accessed by the CPU, e.g. during a page fault. Without this change, TTM could evict other BOs while trying to satisfy the requested placement, even if the evicted BOs were outside of the requested placement range. Doing so didn't free up any space in the requested placement range, so the (potentially high) eviction cost was incurred for no benefit. Nominating for stable because radeon driver changes in 3.17 made this much more noticeable than before. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=84662Signed-off-by:

commit e2cffb5f upstream. On archs with PAGE_SIZE >= 64 KiB the function skcipher_alloc_sgl() fails with -ENOMEM no matter what user space actually requested. This is caused by the fact sock_kmalloc call inside the function tried to allocate more memory than allowed by the default kernel socket buffer size (kernel param net.core.optmem_max). Signed-off-by:

commit b51d3fa3 upstream. The kernel should reserve enough room in the skb so that the DONE message can always be appended. However, in case of e.g. new attribute erronously not being size-accounted for, __nfulnl_send() will still try to put next nlmsg into this full skbuf, causing the skb to be stuck forever and blocking delivery of further messages. Fix issue by releasing skb immediately after nlmsg_put error and WARN() so we can track down the cause of such size mismatch. [ fw@strlen.de: add tailroom/len info to WARN ] Signed-off-by:

commit 9dfa1dfe upstream. We currently neither account for the nlattr size, nor do we consider the size of the trailing NLMSG_DONE when allocating nlmsg skb. This can result in nflog to stop working, as __nfulnl_send() re-tries sending forever if it failed to append NLMSG_DONE (which will never work if buffer is not large enough). Reported-by:

commit 19aeb5a6 upstream. This patch fixes a regression in the patch "GFS2: Remember directory insert point", commit 2b47dad8. The problem had to do with the rename function: The function found space for the new dirent, and remembered that location. But then the old dirent was removed, which often moved the eligible location for the renamed dirent. Putting the new dirent at the saved location caused file system corruption. This patch adds a new "save_loc" variable to struct gfs2_diradd. If 1, the dirent location is saved. If 0, the dirent location is not saved and the buffer_head is released as per previous behavior.

commit 6fbb702e upstream. Linus commit 05c63c2f modified the runtime suspend/resume paths to skip over display-related tasks to avoid locking issues on resume. Unfortunately, this resulted in the display hardware being left in a partially initialised state, preventing subsequent modesets from completing. This commit unifies the (many) suspend/resume paths, bringing back display (and fbcon) handling in the runtime paths. Signed-off-by:

commit 634ffccc upstream. Preparation for some runtime pm fixes. Currently we skip over fbcon suspend/resume in the runtime path, which causes issues on resume if fbcon tries to write to the framebuffer before the BAR subdev has been resumed to restore the BAR1 VM setup. As we might be woken up via a sysfs connector, we are unable to call fb_set_suspend() in the resume path as it could make its way down to a modeset and cause all sorts of locking hilarity. To solve this, we'll just delay the fbcon resume to a workqueue. Signed-off-by:

commit e4a60d13 upstream. There is a race condition when removing glue directory. It can be reproduced in following test: path 1: Add first child device device_add() get_device_parent() /*find parent from glue_dirs.list*/ list_for_each_entry(k, &dev->class->p->glue_dirs.list, entry) if (k->parent == parent_kobj) { kobj = kobject_get(k); break; } .... class_dir_create_and_add() path2: Remove last child device under glue dir device_del() cleanup_device_parent() cleanup_glue_dir() kobject_put(glue_dir); If path2 has been called cleanup_glue_dir(), but not call kobject_put(glue_dir), the glue dir is still in parent's kset list. Meanwhile, path1 find the glue dir from the glue_dirs.list. Path2 may release glue dir before path1 call kobject_get(). So kernel will report the warning and bug_on. This is a "classic" problem we have of a kref in a list that can be found while the last instance could be removed at the same time. This patch reuse gdp_mutex to fix this race condition. The following calltrace is captured in kernel 3.4, but the latest kernel still has this bug. ----------------------------------------------------- <4>[ 3965.441471] WARNING: at ...include/linux/kref.h:41 kobject_get+0x33/0x40() <4>[ 3965.441474] Hardware name: Romley <4>[ 3965.441475] Modules linked in: isd_iop(O) isd_xda(O)... ... <4>[ 3965.441605] Call Trace: <4>[ 3965.441611] [<ffffffff8103717a>] warn_slowpath_common+0x7a/0xb0 <4>[ 3965.441615] [<ffffffff810371c5>] warn_slowpath_null+0x15/0x20 <4>[ 3965.441618] [<ffffffff81215963>] kobject_get+0x33/0x40 <4>[ 3965.441624] [<ffffffff812d1e45>] get_device_parent.isra.11+0x135/0x1f0 <4>[ 3965.441627] [<ffffffff812d22d4>] device_add+0xd4/0x6d0 <4>[ 3965.441631] [<ffffffff812d0dbc>] ? dev_set_name+0x3c/0x40 .... <2>[ 3965.441912] kernel BUG at ..../fs/sysfs/group.c:65! <4>[ 3965.441915] invalid opcode: 0000 [#1] SMP ... <4>[ 3965.686743] [<ffffffff811a677e>] sysfs_create_group+0xe/0x10 <4>[ 3965.686748] [<ffffffff810cfb04>] blk_trace_init_sysfs+0x14/0x20 <4>[ 3965.686753] [<ffffffff811fcabb>] blk_register_queue+0x3b/0x120 <4>[ 3965.686756] [<ffffffff812030bc>] add_disk+0x1cc/0x490 .... ------------------------------------------------------- Signed-off-by:

commit 37b16457 upstream. Kernel oops can cause the tty to be unreleaseable (for example, if n_tty_read() crashes while on the read_wait queue). This will cause tty_release() to endlessly loop without sleeping. Use a killable sleep timeout which grows by 2n+1 jiffies over the interval [0, 120 secs.) and then jumps to forever (but still killable). NB: killable just allows for the task to be rewoken manually, not to be terminated. Signed-off-by:

commit 547039ec upstream. uart_get_baud_rate() will return baud == 0 if the max rate is set to the "magic" 38400 rate and the SPD_* flags are also specified. On the first iteration, if the current baud rate is higher than the max, the baud rate is clamped at the max (which in the degenerate case is 38400). On the second iteration, the now-"magic" 38400 baud rate selects the possibly higher alternate baud rate indicated by the SPD_* flag. Since only two loop iterations are performed, the loop is exited, a kernel WARNING is generated and a baud rate of 0 is returned. Reproducible with: setserial /dev/ttyS0 spd_hi base_baud 38400 Only perform the "magic" 38400 -> SPD_* baud transform on the first loop iteration, which prevents the degenerate case from recognizing the clamped baud rate as the "magic" 38400 value.

This is a regression introduced by the commit eb82a3d8 (phy: omap-usb2: Balance pm_runtime_enable() on probe failure and remove). This because the call to pm_runtime_enable() function is moved after the call to devm_phy_create() function, which has side effect since later in the subsequent calls of devm_phy_create() there is a check with pm_runtime_enabled() to configure few things.
