[ Upstream commit b0350d51 ] gre_parse_header stops parsing when csum_err is encountered, which means tpi->key is undefined and ip_tunnel_lookup will return NULL improperly. This patch introduce a NULL pointer as csum_err parameter. Even when csum_err is encountered, it won't return error and continue parsing gre header as expected. Fixes: 9f57c67c ("gre: Remove support for sharing GRE protocol hook.") Reported-by:

[ Upstream commit a75e78f2 ] The terminating NUL byte is only there because the buffer is allocated with kzalloc(PAGE_SIZE, GFP_KERNEL), but since the range-check is off-by-one, and PAGE_SIZE==PATH_MAX, the returned string may not be zero-terminated if it is exactly PATH_MAX characters long. Furthermore also the initial loop may theoretically exceed PATH_MAX and cause a fault. Signed-off-by:

[ Upstream commit bdae566d ] During component_bind_all(), if bind() fails for any particular component associated with a master, unbind() should be called for all previous components in that master's match array, whose bind() might have completed successfully. As per the current logic, if bind() fails for the component at position 'n' in the master's match array, it would start calling unbind() from component in 'n'th position itself and work backwards, and will always skip calling unbind() for component in 0th position in the master's match array. Fix this by updating the loop condition, and the logic to refer to the components in master's match array, so that unbind() is called for all components starting from 'n-1'st position in the array, until (and including) component in 0th position.

[ Upstream commit c8765de0 ] To reduce latency for interactive and soft real-time applications, bfq privileges the bfq_queues containing the I/O of these applications. These privileged queues, referred-to as weight-raised queues, get a much higher share of the device throughput w.r.t. non-privileged queues. To preserve this higher share, the I/O of any non-weight-raised queue must be plugged whenever a sync weight-raised queue, while being served, remains temporarily empty. To attain this goal, bfq simply plugs any I/O (from any queue), if a sync weight-raised queue remains empty while in service. Unfortunately, this plugging typically lowers throughput with random I/O, on devices with internal queueing (because it reduces the filling level of the internal queues of the device). This commit addresses this issue by restricting the cases where plugging is performed: if a sync weight-raised queue remains empty while in service, then I/O plugging is performed only if some of the active bfq_queues are *not* weight-raised (which is actually the only circumstance where plugging is needed to preserve the higher share of the throughput of weight-raised queues). This restriction proved able to boost throughput in really many use cases needing only maximum throughput. Signed-off-by:

[ Upstream commit d0edc247 ] The Achilles' heel of BFQ is its failing to reach a high throughput with sync random I/O on flash storage with internal queueing, in case the processes doing I/O have differentiated weights. The cause of this failure is as follows. If at least two processes do sync I/O, and have a different weight from each other, then BFQ plugs I/O dispatching every time one of these processes, while it is being served, remains temporarily without pending I/O requests. This plugging is necessary to guarantee that every process enjoys a bandwidth proportional to its weight; but it empties the internal queue(s) of the drive. And this kills throughput with random I/O. So, if some processes have differentiated weights and do both sync and random I/O, the end result is a throughput collapse. This commit tries to counter this problem by injecting the service of other processes, in a controlled way, while the process in service happens to have no I/O. This injection is performed only if the medium is non rotational and performs internal queueing, and the process in service does random I/O (service injection might be beneficial for sequential I/O too, we'll work on that). As an example of the benefits of this commit, on a PLEXTOR PX-256M5S SSD, and with five processes having differentiated weights and doing sync random 4KB I/O, this commit makes the throughput with bfq grow by 400%, from 25 to 100MB/s. This higher throughput is 10MB/s lower than that reached with none. As some less random I/O is added to the mix, the throughput becomes equal to or higher than that with none. This commit is a very first attempt to recover throughput without losing control, and certainly has many limitations. One is, e.g., that the processes whose service is injected are not chosen so as to distribute the extra bandwidth they receive in accordance to their weights. Thus there might be loss of weighted fairness in some cases. Anyway, this loss concerns extra service, which would not have been received at all without this commit. Other limitations and issues will probably show up with usage. Signed-off-by:

[ Upstream commit e4ba15de ] The bad_mode() handler is called if we encounter an uunknown exception, with the expectation that the subsequent call to panic() will halt the system. Unfortunately, if the exception calling bad_mode() is taken from EL0, then the call to die() can end up killing the current user task and calling schedule() instead of falling through to panic(). Remove the die() call altogether, since we really want to bring down the machine in this "impossible" case. Signed-off-by:

[ Upstream commit 44b73962 ] When a process dies, failed reply is sent to the sender of any transaction queued on a dead thread's todo list. The sender asserts that the received failed reply corresponds to the head of the transaction stack. This assert can fail if the dead thread is allowed to send outgoing transactions when there is already a transaction on its todo list, because this new transaction can end up on the transaction stack of the original sender. The following steps illustrate how this assertion can fail. 1. Thread1 sends txn19 to Thread2 (T1->transaction_stack=txn19, T2->todo+=txn19) 2. Without processing todo list, Thread2 sends txn20 to Thread1 (T1->todo+=txn20, T2->transaction_stack=txn20) 3. T1 processes txn20 on its todo list (T1->transaction_stack=txn20->txn19, T1->todo=<empty>) 4. T2 dies, T2->todo cleanup attempts to send failed reply for txn19, but T1->transaction_stack points to txn20 -- assertion failes Step 2. is the incorrect behavior. When there is a transaction on a thread's todo list, this thread should not be able to send any outgoing synchronous transactions. Only the head of the todo list needs to be checked because only threads that are waiting for proc work can directly receive work from another thread, and no work is allowed to be queued on such a thread without waking up the thread. This patch also enforces that a thread is not waiting for proc work when a work is directly enqueued to its todo list. Acked-by:

[ Upstream commit 56d20861 ] Call Frame Information is used by gdb for back-traces and inserting breakpoints on function return for the "finish" command. This failed when inside __kernel_clock_gettime. More concerning than difficulty debugging is that CFI is also used by stack frame unwinding code to implement exceptions. If you have an app that needs to handle asynchronous exceptions for some reason, and you are unlucky enough to get one inside the VDSO time functions, your app will crash. What's wrong: There is control flow in __kernel_clock_gettime that reaches label 99 without saving lr in r12. CFI info however is interpreted by the unwinder without reference to control flow: It's a simple matter of "Execute all the CFI opcodes up to the current address". That means the unwinder thinks r12 contains the return address at label 99. Disabuse it of that notion by resetting CFI for the return address at label 99. Note that the ".cfi_restore lr" could have gone anywhere from the "mtlr r12" a few instructions earlier to the instruction at label 99. I put the CFI as late as possible, because in general that's best practice (and if possible grouped with other CFI in order to reduce the number of CFI opcodes executed when unwinding). Using r12 as the return address is perfectly fine after the "mtlr r12" since r12 on that code path still contains the return address. __get_datapage also has a CFI error. That function temporarily saves lr in r0, and reflects that fact with ".cfi_register lr,r0". A later use of r0 means the CFI at that point isn't correct, as r0 no longer contains the return address. Fix that too. Signed-off-by:

[ Upstream commit 867d4aa7 ] The geni_se_clk_freq_match() has some strange semantics. Specifically it is defined with two modes: 1. It can find a clock that's an exact multiple of the requested rate 2. It can find a non-exact match but it can't handle multiples then ...but callers should always be able to handle a clock that is a multiple of the requested clock so mode #2 doesn't really make sense. Let's change the semantics so that the non-exact match can also accept multiples and then change the code to handle that. The only caller of this code is the unlanded SPI driver [1] which currently passes "exact = True", thus it should be safe to change the semantics in this way. ...and, in fact, the SPI driver should likely be modified to pass "exact = False" (with the new semantics) since that will allow it to work with SPI devices that request a clock rate that doesn't exactly match a rate we can make.

Change the call in geni_se_clk_tbl_get() to check for errors. While we're at it, get rid of a useless init of "freq". NOTE: overall the idea that we should iterate over clk_round_rate() to try to reconstruct a table already present in the clock driver is questionable. Specifically: - This method relies on "clk_round_rate()" rounding up. - This method only works if the table is sorted and has no duplicates. ...this patch doesn't try to fix those problems, it just makes the error handling more correct.

Really, we could just check "num_configs" directly and remove the "has_config" variable. Fixes: 77618084 ("pinctrl: introduce driver for Atmel PIO4 controller") Signed-off-by:

[ Upstream commit 1ccbeeb8 ] The VIDEO_GET_EVENT and VIDEO_STILLPICTURE was added back in 2005 but it never worked because the command number is wrong. Using the right command number means we have a better chance of them actually doing the right thing, though clearly nobody has ever tried it successfully. I noticed these while auditing the remaining users of compat_time_t for y2038 bugs. This one is fine in that regard, it just never did anything. Fixes: 6e87abd0 ("[DVB]: Add compat ioctl handling.")
