commit d045c77c upstream. On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y, currently parisc and metag only) stack randomization sometimes leads to crashes when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB by default if not defined in arch-specific headers). The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the additional space needed for the stack randomization (as defined by the value of STACK_RND_MASK) was not taken into account yet and as such, when the stack randomization code added a random offset to the stack start, the stack effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK) which then sometimes leads to out-of-stack situations and crashes. This patch fixes it by adding the maximum possible amount of memory (based on STACK_RND_MASK) which theoretically could be added by the stack randomization code to the initial stack size. That way, the user-defined stack size is always guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK). This bug is currently not visible on the metag architecture, because on metag STACK_RND_MASK is defined to 0 which effectively disables stack randomization. The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP" section, so it does not affect other platformws beside those where the stack grows upwards (parisc and metag). Signed-off-by:

commit ec04847c upstream. The string iwpm_ulib_name is recorded in a nlmsg as a netlink attribute. Without this fix parsing of the nlmsg by the userspace port mapper service fails because of unknown attribute length, causing the port mapper service not to register the client, which has sent the nlmsg.

commit 8f9cfeed upstream. when gsmtty_remove put dlci, it will cause memory leak if dlci->port's refcount is zero. So we do the cleanup work in .cleanup callback instead. dlci will be last put in two call chains. 1) gsmld_close -> gsm_cleanup_mux -> gsm_dlci_release -> dlci_put 2) gsmld_remove -> dlci_put so there is a race. the memory leak depends on the race. In call chain 2. we hit the memory leak. below comment tells. release_tty -> tty_driver_remove_tty -> gsmtty_remove -> dlci_put -> tty_port_destructor (WARN_ON(port->itty) and return directly) | tty->port->itty = NULL; | tty_kref_put ---> release_one_tty -> gsmtty_cleanup (added by our patch) So our patch fix the memory leak by doing the cleanup work after tty core did.

commit 18cc2f4c upstream. Our event ring consists of only one segment, and we risk filling the event ring in case we get isoc transfers with short intervals such as webcams that fill a TD every microframe (125us) With 64 TRB segment size one usb camera could fill the event ring in 8ms. A setup with several cameras and other devices can fill up the event ring as it is shared between all devices. This has occurred when uvcvideo queues 5 * 32TD URBs which then get cancelled when the video mode changes. The cancelled URBs are returned in the xhci interrupt context and blocks the interrupt handler from handling the new events. A full event ring will block xhci from scheduling traffic and affect all devices conneted to the xhci, will see errors such as Missed Service Intervals for isoc devices, and and Split transaction errors for LS/FS interrupt devices. Increasing the TRB_PER_SEGMENT will also increase the default endpoint ring size, which is welcome as for most isoc transfer we had to dynamically expand the endpoint ring anyway to be able to queue the 5 * 32TDs uvcvideo queues. The default size used to be 64 TRBs per segment Signed-off-by:

commit d104d015 upstream. Isoc TDs usually consist of one TRB, sometimes two. When all goes well we receive only one success event for a TD, and move the dequeue pointer to the next TD. This fails if the TD consists of two TRBs and we get a transfer error on the first TRB, we will then see two events for that TD. Fix this by making sure the event we get is for the last TRB in that TD before moving the dequeue pointer to the next TD. This will resolve some of the uvc and dvb issues with the "ERROR Transfer event TRB DMA ptr not part of current TD" error message Signed-off-by:

commit 0782e63b upstream. Ronny reported that the following scenario is not handled correctly: T1 (prio = 10) lock(rtmutex); T2 (prio = 20) lock(rtmutex) boost T1 T1 (prio = 20) sys_set_scheduler(prio = 30) T1 prio = 30 .... sys_set_scheduler(prio = 10) T1 prio = 30 The last step is wrong as T1 should now be back at prio 20. Commit c365c292 ("sched: Consider pi boosting in setscheduler()") only handles the case where a boosted tasks tries to lower its priority. Fix it by taking the new effective priority into account for the decision whether a change of the priority is required. Reported-by:

commit 6e9eac2d upstream. If any memory allocation in resize_stripes fails we will return -ENOMEM, but in some cases we update conf->pool_size anyway. This means that if we try again, the allocations will be assumed to be larger than they are, and badness results. So only update pool_size if there is no error. This bug was introduced in 2.6.17 and the patch is suitable for -stable. Fixes: ad01c9e3 ("[PATCH] md: Allow stripes to be expanded in preparation for expanding an array") Signed-off-by:

commit b9a5e5e1 upstream. Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence. Reported-and-tested-by:

commit 9507271d upstream. In an environment where the KDC is running Active Directory, the exported composite name field returned in the context could be large enough to span a page boundary. Attaching a scratch buffer to the decoding xdr_stream helps deal with those cases. The case where we saw this was actually due to behavior that's been fixed in newer gss-proxy versions, but we're fixing it here too. Signed-off-by:

commit 5793affe upstream. Using IDR_SRR in RXFIFO_ID to test for the presence of data is only valid for standard frames. For extended frames the bit is always 1 and IDR_RTR should be used instead. This patch switches the check to use CAN_RTR_FLAG which is correctly set when reading the ID. The patch also changes the DW1/DW2 to be read unconditionally, since this is necessary to remove the frame from the RXFIFO. Signed-off-by:

commit 82ee3aeb upstream. Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.

When gadget is composed with configfs configuration structure may be reused for different functions set. This bug happens because purge_configs_funcs() sets only next_interface_id to 0. Interface array still contains pointers to already freed interfaces. If in second try we add less interfaces than earlier we may access unallocated memory when trying to get interface descriptors.

commit 8e71c04f upstream. In SPI mode the transfer buffer is locked with a mutex. However this mutex is only initilized after the probe, but some transfer needs to be done in the probe. To fix this bug we move the mutex initialization at the beginning of the device probe. Signed-off-by:

commit 09c5b480 upstream. When the LPM policy is set to ATA_LPM_MAX_POWER, the device might generate a spurious PHY event that cuases errors on the link. Ignore this event if it occured within 10s after the policy change. The timeout was chosen observing that on a Dell XPS13 9333 these spurious events can occur up to roughly 6s after the policy change.

commit 97ffae1d upstream. The VREFN channel is bipolar, not unipolar. Small negative values do occur (e.g., -1mV), and unsigned conversion maps them incorrectly to large positive values (about +1V), so fix this. Signed-off-by:

commit c80e5c0c upstream. On x86-64, __copy_instruction() always returns 0 (error) if the instruction uses %rip-relative addressing. This is because kernel_insn_init() is called the second time for 'insn' instance in such cases and sets all its fields to 0. Because of this, trying to place a kprobe on such instruction will fail, register_kprobe() will return -EINVAL. This patch fixes the problem. Signed-off-by:
