2012-11-23mtip32xx: fix potential crash on SEC_ERASE_UNITSelvan Mani
The mtip driver lifted this code from elsewhere and then added a special handling check for SEC_ERASE_UNIT. If the caller tries to do a security erase but passes no output data for the command then outbuf is not allocated and the driver duly explodes.

2012-11-23dm: fix deadlock with request based dm and queue request_fn recursionJens Axboe
Request based dm attempts to re-run the request queue off the request completion path. If used with a driver that potentially does end_io from its request_fn, we could deadlock trying to recurse back into request dispatch. Fix this by punting the request queue run to kblockd. Tested to fix a quickly reproducible deadlock in such a scenario. Cc: stable@kernel.org Acked-by: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2012-11-23floppy: destroy floppy workqueue before cleaning up the queueJiri Kosina
We need to first destroy the floppy_wq workqueue before cleaning up the queue. Otherwise we might race with still pending work with the workqueue, but all the block queue already gone.

When sending data into a tcp socket in repair state we should check for the amount of data being 0 explicitly.

2012-11-02l2tp: fix oops in l2tp_eth_create() error pathTom Parkin
When creating an L2TPv3 Ethernet session, if register_netdev() should fail for any reason (for example, automatic naming for "l2tpeth%d" interfaces hits the 32k-interface limit), the netdev is freed in the error path. However, the l2tp_eth_sess structure's dev pointer is left uncleared, and this results in l2tp_eth_delete() then attempting to unregister the same netdev later in the session teardown. This results in an oops. To avoid this, clear the session dev pointer in the error path. Signed-off-by: Tom Parkin <tparkin@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The kernel_thread() changes for FRV don't work, and FRV fails to boot, starting with: commit 02ce496f152df87be081a64796498942c433a2fd Author: Al Viro <viro@zeniv.linux.org.uk> Date: Tue Sep 18 22:18:51 2012 -0400 Subject: frv: split ret_from_fork, simplify kernel_thread() a lot The problem is that the userspace registers are completely cleared when a kernel thread is created and all subsequent user threads are then copied from that. Unfortunately, however, the TBR and PSR registers are restored from the pt_regs and the values they should be set to are clobbered by the memset. Instead, copy across the old user registers as normal, and then merely alter GR8 and GR9 in it if we're going to execute a kernel thread. Signed-off-by: David Howells <dhowells@redhat.com>
2012-11-02FRV: Fix the preemption handlingDavid Howells
Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is incorrectly loaded into the threadinfo flags rather than the threadinfo preemption count. Unfortunately, the code cannot be simply converted to use preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to cut down on the cost of actually disabling interrupts and thus local_irq_enable() doesn't actually enable interrupts.

2012-11-02i2c: mxs: remove broken PIOQUEUE supportWolfram Sang
This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally, only PIOQUEUE was supported and it had issues, then DMA support was added this cycle. The original intention was to keep PIOQUEUE since it has less overhead what is nice for small transfers. However, runtime switching between PIOQEUE and DMA depending on the transfer size never worked despite a lot of trying. Since PIOQUEUE mode itself was flaky (polling at places where interrupts failed to work) and the implementation also imposed a size limit for transfers, it is best to remove the support, so users don't fall over its limitations. It also makes the driver a lot cleaner and more robust. If somebody really wants less overhead, plain PIO mode could still be implemented with the addidtional advantage that this mode is also available on MX23, too.

2012-11-02drm/udl: fix stride issues scanning out stride != width*bppDave Airlie
When buffer sharing with the i915 and using a 1680x1050 monitor, the i915 gives is a 6912 buffer for the 6720 width, the code doesn't render this properly as it uses one value to set the base address for reading from the vmap and for where to start on the device. This fixes it by calculating the values correctly for the device and for the pixmap. No idea how I haven't seen this before now.

The following fixes build errors on sparc. Without any DT support, of_match_ptr is NULL and the below is a no-op. However, if just CONFIG_OF is defined then so is of_match_ptr. All useful parts of the gpio-fan DT support rely on CONFIG_OF_GPIO anyway, so of_match_table should too.

2012-11-01net: fix divide by zero in tcp algorithm illinoisJesper Dangaard Brouer
Reading TCP stats when using TCP Illinois congestion control algorithm can cause a divide by zero kernel oops. The division by zero occur in tcp_illinois_info() at: do_div(t, ca->cnt_rtt); where ca->cnt_rtt can become zero (when rtt_reset is called) Steps to Reproduce: 1. Register tcp_illinois: # sysctl -w net.ipv4.tcp_congestion_control=illinois 2. Monitor internal TCP information via command "ss -i" # watch -d ss -i 3. Establish new TCP conn to machine Either it fails at the initial conn, or else it needs to wait for a loss or a reset. This is only related to reading stats. The function avg_delay() also performs the same divide, but is guarded with a (ca->cnt_rtt > 0) at its calling point in update_params(). Thus, simply fix tcp_illinois_info(). Function tcp_illinois_info() / get_info() is called without socket lock. Thus, eliminate any race condition on ca->cnt_rtt by using a local stack variable. Simply reuse info.tcpv_rttcnt, as its already set to ca->cnt_rtt. Function avg_delay() is not affected by this race condition, as its called with the socket lock.
