commit cea27eb2 upstream. The logic for the memory-remove code fails to correctly account the Total High Memory when a memory block which contains High Memory is offlined as shown in the example below. The following patch fixes it.

commit 07f3cb7c upstream. Xhci controllers with hci_version > 0.96 gives spurious success events on short packet completion. During webcam capture the "ERROR Transfer event TRB DMA ptr not part of current TD" was observed. The same application works fine with synopsis controllers hci_version 0.96. The same issue is seen with Intel Pantherpoint xhci controller. So enabling this quirk in xhci_gen_setup if controller verion is greater than 0.96. For xhci-pci move the quirk to much generic place xhci_gen_setup. Note from Sarah: The xHCI 1.0 spec changed how hardware handles short packets. The HW will notify SW of the TRB where the short packet occurred, and it will also give a successful status for the last TRB in a TD (the one with the IOC flag set). On the second successful status, that warning will be triggered in the driver. Software is now supposed to not assume the TD is not completed until it gets that last successful status. That means we have a slight race condition, although it should have little practical impact. This patch papers over that issue. It's on my long-term to-do list to fix this race condition, but it is a much more involved patch that will probably be too big for stable. This patch is needed for stable to avoid serious log spam. This patch should be backported to kernels as old as 3.0, that contain the commit ad808333 "Intel xhci: Ignore spurious successful event." The patch will have to be modified for kernels older than 3.2, since that kernel added the xhci_gen_setup function for xhci platform devices. The correct conflict resolution for kernels older than 3.2 is to set XHCI_SPURIOUS_SUCCESS in xhci_pci_quirks for all xHCI 1.0 hosts. Signed-off-by:

commit 203a8661 upstream. When the host controller fails to respond to an Enable Slot command, and the host fails to respond to the register write to abort the command ring, the xHCI driver will assume the host is dead, and call usb_hc_died(). The USB device's slot_id is still set to zero, and the pointer stored at xhci->devs[0] will always be NULL. The call to xhci_check_args in xhci_free_dev should have caught the NULL virt_dev pointer. However, xhci_free_dev is designed to free the xhci_virt_device structures, even if the host is dead, so that we don't leak kernel memory. xhci_free_dev checks the return value from the generic xhci_check_args function. If the return value is -ENODEV, it carries on trying to free the virtual device. The issue is that xhci_check_args looks at the host controller state before it looks at the xhci_virt_device pointer. It will return -ENIVAL because the host is dead, and xhci_free_dev will ignore the return value, and happily dereference the NULL xhci_virt_device pointer. The fix is to make sure that xhci_check_args checks the xhci_virt_device pointer before it checks the host state. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203453 for further details. This patch doesn't solve the underlying issue, but will ensure we don't see any more NULL pointer dereferences because of the issue. This patch should be backported to kernels as old as 3.1, that contain the commit 7bd89b40 "xhci: Don't submit commands or URBs to halted hosts." Signed-off-by:

commit 0e0ed640 upstream. Module CRCs are implemented as absolute symbols that get resolved by a linker script. We build an intermediate .o that contains an unresolved symbol for each CRC. genksysms parses this .o, calculates the CRCs and writes a linker script that "resolves" the symbols to the calculated CRC. Unfortunately the ppc64 relocatable kernel sees these CRCs as symbols that need relocating and relocates them at boot. Commit d4703aef (module: handle ppc64 relocating kcrctabs when CONFIG_RELOCATABLE=y) added a hook to reverse the bogus relocations. Part of this patch created a symbol at 0x0: # head -2 /proc/kallsyms 0000000000000000 T reloc_start c000000000000000 T .__start This reloc_start symbol is causing lots of confusion to perf. It thinks reloc_start is a massive function that stretches from 0x0 to 0xc000000000000000 and we get various cryptic errors out of perf, including: problem incrementing symbol count, skipping event This patch removes the reloc_start linker script label and instead defines it as PHYSICAL_START. We also need to wrap it with CONFIG_PPC64 because the ppc32 kernel can set a non zero PHYSICAL_START at compile time and we wouldn't want to subtract it from the CRCs in that case. Signed-off-by:

commit 4b18f08b upstream. `do_cmd_ioctl()` is called with the comedi device's mutex locked to process the `COMEDI_CMD` ioctl to set up comedi's asynchronous command handling on a comedi subdevice. `comedi_read()` and `comedi_write()` are the `read` and `write` handlers for the comedi device, but do not lock the mutex (for performance reasons, as some things can hold the mutex for quite a long time). There is a race condition if `comedi_read()` or `comedi_write()` is running at the same time and for the same file object and comedi subdevice as `do_cmd_ioctl()`. `do_cmd_ioctl()` sets the subdevice's `busy` pointer to the file object way before it sets the `SRF_RUNNING` flag in the subdevice's `runflags` member. `comedi_read() and `comedi_write()` check the subdevice's `busy` pointer is pointing to the current file object, then if the `SRF_RUNNING` flag is not set, will call `do_become_nonbusy()` to shut down the asyncronous command. Bad things can happen if the asynchronous command is being shutdown and set up at the same time. To prevent the race, don't set the `busy` pointer until after the `SRF_RUNNING` flag has been set. Also, make sure the mutex is held in `comedi_read()` and `comedi_write()` while calling `do_become_nonbusy()` in order to avoid moving the race condition to a point within that function. Change some error handling `goto cleanup` statements in `do_cmd_ioctl()` to simple `return -ERRFOO` statements as a result of changing when the `busy` pointer is set. Signed-off-by:

commit 69acbaac upstream. Comedi devices can do blocking read() or write() (or poll()) if an asynchronous command has been set up, blocking for data (for read()) or buffer space (for write()). Various events associated with the asynchronous command will wake up the blocked reader or writer (or poller). It is also possible to force the asynchronous command to terminate by issuing a `COMEDI_CANCEL` ioctl. That shuts down the asynchronous command, but does not currently wake up the blocked reader or writer (or poller). If the blocked task could be woken up, it would see that the command is no longer active and return. The caller of the `COMEDI_CANCEL` ioctl could attempt to wake up the blocked task by sending a signal, but that's a nasty workaround. Change `do_cancel_ioctl()` to wake up the wait queue after it returns from `do_cancel()`. `do_cancel()` can propagate an error return value from the low-level comedi driver's cancel routine, but it always shuts the command down regardless, so `do_cancel_ioctl()` can wake up he wait queue regardless of the return value from `do_cancel()`.

commit e4daf1ff upstream. The following call chain: ------------------------------------------------------------ nfs4_get_vfs_file - nfsd_open - dentry_open - do_dentry_open - __get_file_write_access - get_write_access - return atomic_inc_unless_negative(&inode->i_writecount) ? 0 : -ETXTBSY; ------------------------------------------------------------ can result in the following state: ------------------------------------------------------------ struct nfs4_file { ... fi_fds = {0xffff880c1fa65c80, 0xffffffffffffffe6, 0x0}, fi_access = {{ counter = 0x1 }, { counter = 0x0 }}, ... ------------------------------------------------------------ 1) First time around, in nfs4_get_vfs_file() fp->fi_fds[O_WRONLY] is NULL, hence nfsd_open() is called where we get status set to an error and fp->fi_fds[O_WRONLY] to -ETXTBSY. Thus we do not reach nfs4_file_get_access() and fi_access[O_WRONLY] is not incremented. 2) Second time around, in nfs4_get_vfs_file() fp->fi_fds[O_WRONLY] is NOT NULL (-ETXTBSY), so nfsd_open() is NOT called, but nfs4_file_get_access() IS called and fi_access[O_WRONLY] is incremented. Thus we leave a landmine in the form of the nfs4_file data structure in an incorrect state. 3) Eventually, when __nfs4_file_put_access() is called it finds fi_access[O_WRONLY] being non-zero, it decrements it and calls nfs4_file_put_fd() which tries to fput -ETXTBSY. ------------------------------------------------------------ ...

commit 085b513f upstream. sd_prep_fn will allocate a larger CDB for the command via mempool_alloc for devices using DIF type 2 protection. This CDB was being freed in sd_done, which results in a kernel crash if the command is retried due to a UNIT ATTENTION. This change moves the code to free the larger CDB into sd_unprep_fn instead, which is invoked after the request is complete. It is no longer necessary to call scsi_print_command separately for this case as the ->cmnd will no longer be NULL in the normal code path. Also removed conditional test for DIF type 2 when freeing the larger CDB because the protection_type could have been changed via sysfs while the command was executing. Signed-off-by:

commit 96f15f29 upstream. This commit fixes a race condition in the isci driver abort task and SSP device task management path. The race is caused when an I/O termination in the SCU hardware is necessary because of an SSP target timeout condition, and the check of the I/O end state races against the HW-termination-driven end state. The failure of the race meant that no TMF was sent to the device to clean-up the pending I/O. Signed-off-by:

commit cef1d00c upstream. Noticed that my old Radeon 7500 hung after printing drm: GPU not posted. posting now... when it wasn't selected as the primary card the BIOS. Some digging revealed that it was hanging in combios_parse_mmio_table() while parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card, it becomes obvious that there is no ASIC INIT 3 table in the BIOS. The code is just processing random garbage. No surprise it hangs! Why do I say that there is no ASIC INIT 3 table is the BIOS? This table is found through the MISC INFO table. The MISC INFO table can be found at offset 0x5e in the COMBIOS header. But the header is smaller than that. The COMBIOS header starts at offset 0x126. The standard PCI Data Structure (the bit that starts with 'PCIR') lives at offset 0x180. That means that the COMBIOS header can not be larger than 0x5a bytes and therefore cannot contain a MISC INFO table. I looked at a dozen or so BIOS images, some my own, some downloaded from: <http://www.techpowerup.com/vgabios/index.php?manufacturer=ATI&page=1> It is fairly obvious that the size of the COMBIOS header can be found at offset 0x6 of the header. Not sure if it is a 16-bit number or just an 8-bit number, but that doesn't really matter since the tables seems to be always smaller than 256 bytes. So I think combios_get_table_offset() should check if the requested table is present. This can be done by checking the offset against the size of the header. See the diff below. The diff is against the WIP OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this point. But I don't think this bit of the code changed much since then. For what it is worth: Signed-off-by:

commit d29a9f62 upstream. If we stop dropping a root for whatever reason we need to add it back to the dead root list so that we will re-start the dropping next transaction commit. The other case this happens is if we recover a drop because we will add a root without adding it to the fs radix tree, so we can leak it's root and commit root extent buffer, adding this to the dead root list makes this cleanup happen.

commit fec386ac upstream. We aren't setting path->locks[level] when we resume a snapshot deletion which means we won't unlock the buffer when we free the path. This causes deadlocks if we happen to re-allocate the block before we've evicted the extent buffer from cache. Thanks, Reported-by:
