2014-09-17iscsi-target: Fix memory corruption in iscsit_logout_post_handler_diffcidNicholas Bellinger
This patch fixes a bug in iscsit_logout_post_handler_diffcid() where a pointer used as storage for list_for_each_entry() was incorrectly being used to determine if no matching entry had been found. This patch changes iscsit_logout_post_handler_diffcid() to key off bool conn_found to determine if the function needs to exit early.

2014-09-17Revert "init: make rootdelay=N consistent with rootwait behaviour"Paul Gortmaker
This reverts commit 4dfe694f616e00e6fd83e5bbcd7a3c4d7113493d. In that, we did: Here we move the rootdelay code to be right beside the rootwait code, so that their behaviour is consistent. ...which is fine, but in hindsight, perhaps moving the rootwait to be beside the rootdelay would have been better. We also indicated: It should be noted that in doing so, the actions based on the saved_root_name[0] and initrd_load() were previously put on hold by rootdelay=N and now currently will not be delayed. However, I think consistent behaviour is more important than matching historical behaviour of delaying the above two operations. But Pavel reported an instance where an ARM target with root on MMC was failing to mount root, and Russell diagnosed it to the fact that the call to set ROOT_DEV within the saved_root_name[0] processing block mentioned above was no longer being delayed. Rather than moving both wait clauses to the original position of rootdelay and risking unearthing other possible corner case breakage at this point in time, we simply revert now and we can revisit trying the alternate/earlier location in another development cycle.

2014-09-17MIPS: SmartMIPS: Disable assembler warningsMarkos Chandras
The kernel code overrides the default ISA as passed by the compiler in quite a few places. This has unfortunate side effects when smartmips is enabled leading to hundreds of warnings during build such as: {standard input}: Assembler messages: {standard input}:411: Warning: the `smartmips' extension requires MIPS32 revision 1 or greater {standard input}: Assembler messages: {standard input}:43: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension [...] Until the kernel code is fixed properly (if possible), disable all the assembler warning messages to make the build logs readable again. This has no runtime side effects but it makes it easier to spot more critical warnings and problems during build.

2014-09-16Btrfs: set inode's logged_trans/last_log_commit after ranged fsyncFilipe Manana
When a ranged fsync finishes if there are still extent maps in the modified list, still set the inode's logged_trans and last_log_commit. This is important in case an inode is fsync'ed and unlinked in the same transaction, to ensure its inode ref gets deleted from the log and the respective dentries in its parent are deleted too from the log (if the parent directory was fsync'ed in the same transaction). Instead make btrfs_inode_in_log() return false if the list of modified extent maps isn't empty. This is an incremental on top of the v4 version of the patch: "Btrfs: fix fsync data loss after a ranged fsync" which was added to its v5, but didn't make it on time.

2014-09-16vgaarb: Don't default exclusively to first video device with mem+ioBruno Prémont
Commit 20cde694027e ("x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()") moved boot video device detection from efifb to x86 and ia64 pci/fixup.c. For dual-GPU Apple computers above change represents a regression as code in efifb did forcefully override vga_default_device while the merge did not (vgaarb happens prior to PCI fixup). To improve on initial device selection by vgaarb (it cannot know if PCI device not behind bridges see/decode legacy VGA I/O or not), move the screen_info based check from pci_video_fixup() to vgaarb's init function and use it to refine/override decision taken while adding the individual PCI VGA devices. This way PCI fixup has no reason to adjust vga_default_device anymore but can depend on its value for flagging shadowed VBIOS. This has the nice benefit of removing duplicated code but does introduce a #if defined() block in vgaarb. Not all architectures have screen_info and would cause compile to fail without it.

2014-09-16ARM: 8148/1: flush TLS and thumbee register state during execNathan Lynch
The TPIDRURO and TPIDRURW registers need to be flushed during exec; otherwise TLS information is potentially leaked. TPIDRURO in particular needs careful treatment. Since flush_thread basically needs the same code used to set the TLS in arm_syscall, pull that into a common set_tls helper in tls.h and use it in both places. Similarly, TEEHBR needs to be cleared during exec as well. Clearing its save slot in thread_info isn't right as there is no guarantee that a thread switch will occur before the new program runs. Just setting the register directly is sufficient.

2014-09-16usb: gadget: f_fs: virtual endpoint address mappingRobert Baldyga
This patch introduces virtual endpoint address mapping. It separates function logic form physical endpoint addresses making it more hardware independent. Following modifications changes user space API, so to enable them user have to switch on the FUNCTIONFS_VIRTUAL_ADDR flag in descriptors. Endpoints are now refered using virtual endpoint addresses chosen by user in endpoint descpriptors. This applies to each context when endpoint address can be used: - when accessing endpoint files in FunctionFS filesystemi (in file name), - in setup requests directed to specific endpoint (in wIndex field), - in descriptors returned by FUNCTIONFS_ENDPOINT_DESC ioctl. In endpoint file names the endpoint address number is formatted as double-digit hexadecimal value ("ep%02x") which has few advantages - it is easy to parse, allows to easly recognize endpoint direction basing on its name (IN endpoint number starts with digit 8, and OUT with 0) which can be useful for debugging purpose, and it makes easier to introduce further features allowing to use each endpoint number in both directions to have more endpoints available for function if hardware supports this (for example we could have ep01 which is endpoint 1 with OUT direction, and ep81 which is endpoint 1 with IN direction). Physical endpoint address can be still obtained using ioctl named FUNCTIONFS_ENDPOINT_REVMAP, but now it's not neccesary to handle USB transactions properly.

2014-09-15iscsi-target: Ignore ICF_GOT_LAST_DATAOUT during Data-Out ITT lookupNicholas Bellinger
This patch adds a explicit check in iscsit_find_cmd_from_itt_or_dump() to ignore commands with ICF_GOT_LAST_DATAOUT set. This is done to address the case where an ITT is being reused for DataOUT, but the previous command with the same ITT has not yet been acknowledged by ExpStatSN and removed from the per connection command list. This issue was originally manifesting itself by referencing the previous command during ITT lookup, and subsequently hitting the check in iscsit_check_dataout_hdr() for ICF_GOT_LAST_DATAOUT, that resulted in the DataOUT PDU + associated payload being silently dumped.

2014-09-15vfs: simplify and shrink stack frame of link_path_walk()Linus Torvalds
Commit 9226b5b440f2 ("vfs: avoid non-forwarding large load after small store in path lookup") made link_path_walk() always access the "hash_len" field as a single 64-bit entity, in order to avoid mixed size accesses to the members. However, what I didn't notice was that that effectively means that the whole "struct qstr this" is now basically redundant. We already explicitly track the "const char *name", and if we just use "u64 hash_len" instead of "long len", there is nothing else left of the "struct qstr". We do end up wanting the "struct qstr" if we have a filesystem with a "d_hash()" function, but that's a rare case, and we might as well then just squirrell away the name and hash_len at that point. End result: fewer live variables in the loop, a smaller stack frame, and better code generation. And we don't need to pass in pointers variables to helper functions any more, because the return value contains all the relevant information. So this removes more lines than it adds, and the source code is clearer too. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-09-15USB: serial: remove zte_ev driverJohan Hovold
The zte_ev driver is based on code (once) distributed by ZTE that still appears to originally have been reverse-engineered and bolted onto the generic driver. A closer analysis of the zte_ev setup code reveals that it consists of standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE) but unfortunately fails to get some of those right. In particular, as reported by Lei Liu, it fails to lower DTR/RTS on close. It also appears that the control requests lack the interface argument. Since line control is already handled properly by the option driver, and the SET/GET_LINE_CODING requests appears to be redundant (amounts to a SET 9600 8N1) let's remove the redundant zte_ev driver. Also move the remaining ZTE PIDs to the generic option modem driver. Reported-by: Lei Liu <liu.lei78@zte.com.cn> Signed-off-by: Johan Hovold <johan@kernel.org>
