As observed and suggested by Tushar Gosavi... --------- readdir calls these function to send TRANS2_FIND_FIRST and TRANS2_FIND_NEXT command to the server. The current cifs module is not specifying CIFS_SEARCH_BACKUP_SEARCH flag while sending these command when backupuid/backupgid is specified. This can be resolved by specifying CIFS_SEARCH_BACKUP_SEARCH flag. --------- Cc: <stable@kernel.org> Reported-and-Tested-by:

to handle SMB2 lock type field further. Acked-by:

Pavel Shilovsky authored
CIFS brlock cache can be used by several file handles if we have a write-caching lease on the file that is supported by SMB2 protocol. Prepate the code to handle this situation correctly by sorting brlocks by a fid to easily push them in portions when lease break comes. Signed-off-by: -

For SMB2, this should be a no-op. Obviously if we wanted to do something for the SMB2 case, we could also define an operation here for it. Signed-off-by:

We need a way to dispatch different operations for different versions. Behold the smb_version_operations/values structures. For now, those structures just hold the version enum value and nothing uses them. Eventually, we'll expand them to cover other operations/values as we change the callers to dispatch from here.

Jeff Layton authored
Currently, we have several mount options that control cifs' cache behavior, but those options aren't considered to be mutually exclusive. The result is poorly-defined when someone specifies more than one of these options at mount time. Fix this by adding a new cache= mount option that will supercede "strictcache", and "forcedirectio". That will help make it clear that these options are mutually exclusive. Also, change the legacy options to be mutually exclusive too, to ensure that users don't get surprises. Reviewed-by:

Convert cifs_iovec_read to use async I/O. This also raises the limit on the rsize for uncached reads. We first allocate a set of pages to hold the replies, then issue the reads in parallel and then collect the replies and copy the results into the iovec. A possible future optimization would be to kmap and inline the iovec buffers and read the data directly from the socket into that. That would require some rather complex conversion of the iovec into a kvec however. Signed-off-by: -

We'll need this same bit of code for the uncached case. Signed-off-by: -
Jeff Layton authored
This isn't strictly necessary for the async readpages code, but the uncached version will need to be able to collect the replies after issuing the calls. Add a kref to cifs_readdata and use change the code to take and put references appropriately. Signed-off-by: -
Jeff Layton authored
Cached and uncached reads will need to do different things here to handle the difference when the pages are in pagecache and not. Abstract out the function that marshals the page list into a kvec array. Signed-off-by: -
Jeff Layton authored
We'll need different completion routines for an uncached read. Allow the caller to set the one he needs at allocation time. Also, move most of these functions to file.c so we can make more of them static. Signed-off-by:

Pull networking tree from David Miller: 1) ptp_pch driver build broke during this merge window due to missing slab.h header, fix from Geery Uytterhoeven. 2) If ipset passes in a bogus hash table size we crash because the size is not validated properly. Compounding this, gcc-4.7 can miscompile ipset such that even when the user specifies legitimate parameters the tool passes in an out-of-range size to the kernel. Fix from Jozsef Kadlecsik. 3) Users have reported that the netdev watchdog can trigger with pch_gbe devices, and it turns out this is happening because of races in the TX path of the driver leading to the transmitter hanging. Fix from Eric Dumazet, reported and tested by Andy Cress. 4) Novatel USB551L devices match the generic class entries for the cdc ethernet USB driver, but they don't work because they have generic descriptors and thus need FLAG_WWAN to function properly. Add the necessary ID table entry to fix this, from Dan Williams. 5) A recursive locking fix in the USBNET driver added a new problem, in that packet list traversal is now racy and we can thus access unlinked SKBs and crash. Avoid this situation by adding some extra state tracking, from Ming Lei. 6) The rtlwifi conversion to asynchronous firmware loading is racy, fix by reordering the probe procedure. From Larry Finger. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187 7) Fix regressions with bluetooth keyboards by notifying userland properly when the security level changes, from Gustavo Padovan. 8) Bluetooth needs to make sure device connected events are emitted before other kinds of events, otherwise userspace will think there is no baseband link yet and therefore abort the sockets associated with that connection. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netfilter: ipset: fix hash size checking in kernel ptp_pch: Add missing #include <linux/slab.h> pch_gbe: fix transmit races cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN usbnet: fix skb traversing races during unlink(v2) Bluetooth: mgmt: Fix device_connected sending order Bluetooth: notify userspace of security level change rtlwifi: fix for race condition when firmware is cached

First, we were at risk of handling thread-info flags, in particular do_signal(), when returning from kernel space. This could happen after a failed kernel_execve(), or when forking a kernel thread. The fix is to test in do_work_pending() for user_mode() and return immediately if so; we already had this test for one of the flags, so I just hoisted it to the top of the function. Second, if a ptraced process updated the callee-saved registers in the ptregs struct and then processed another thread-info flag, we would overwrite the modifications with the original callee-saved registers. To fix this, we add a register to note if we've already saved the registers once, and skip doing it on additional passes through the loop. To avoid a performance hit from the couple of extra instructions involved, I modified the GET_THREAD_INFO() macro to be guaranteed to be one instruction, then bundled it with adjacent instructions, yielding an overall net savings.

When handling the H_BULK_REMOVE hypercall, we were forgetting to invalidate and unlock the hashed page table entry (HPTE) in the case where the page had been paged out. This fixes it by clearing the first doubleword of the HPTE in that case. This fixes a regression introduced in commit a92bce95 ("KVM: PPC: Book3S HV: Keep HPTE locked when invalidating"). The effect of the regression is that the host kernel will sometimes hang when under memory pressure. Signed-off-by:

The code forgot to scramble the VSIDs the way we normally do and was basically using the "proto VSID" directly with the MMU. This means that in practice, KVM used random VSIDs that could collide with segments used by other user space programs. Signed-off-by:

When jumping back into the kernel to code that knows that it would be using HSRR registers instead of SRR registers, we need to make sure we pass it all information on where to jump to in HSRR registers. Unfortunately, we used r10 to store the information to distinguish between the HSRR and SRR case. That register got clobbered in between though, rendering the later comparison invalid. Instead, let's use cr1 to store this information. That way we don't need yet another register and everyone's happy. This fixes PR KVM on POWER7 bare metal for me. Signed-off-by: -

When running on a system that is HV capable, some interrupts use HSRR SPRs instead of the normal SRR SPRs. These are also used in the Linux handlers to jump back to code after an interrupt got processed. Unfortunately, in our "jump back to the real host handler after we've done the context switch" code, we were only setting the SRR SPRs, rendering Linux to jump back to some invalid IP after it's processed the interrupt. This fixes random crashes on p7 opal mode with PR KVM for me. Signed-off-by:
