commit eda3913b upstream. The perf_event_attr struct has two __u32's at the top and they need to be swapped individually. With this change I was able to analyze a perf.data collected in a 32-bit PPC VM on an x86 system. I tested both 32-bit and 64-bit binaries for the Intel analysis side; both read the PPC perf.data file correctly. -v2: - changed the existing perf_event__attr_swap() to swap only elements of perf_event_attr and exported it for use in swapping the attributes in the file header - updated swap_ops used for processing events Signed-off-by:

commit 08a4a43f upstream. Builds for 32-bit perf binaries on a 64-bit host currently fail with this error: [...] bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages: bench/../../../arch/x86/lib/memcpy_64.S:29: Error: bad register name `%rdi' bench/../../../arch/x86/lib/memcpy_64.S:34: Error: invalid instruction suffix for `movs' bench/../../../arch/x86/lib/memcpy_64.S:50: Error: bad register name `%rdi' bench/../../../arch/x86/lib/memcpy_64.S:61: Error: bad register name `%rdi' ... The problem is the detection of the host arch without considering passed in flags. This change fixes 32-bit builds via: make EXTRA_CFLAGS=-m32 and 64-bit builds still reference the memcpy_64.S.

commit fd1b6c4a upstream. SCSI scanning of a channel:id:lun triplet in Linux works as follows (function scsi_scan_target() in drivers/scsi/scsi_scan.c): - If lun == SCAN_WILD_CARD, send a REPORT LUNS command to the target and process the result. - If lun != SCAN_WILD_CARD, send an INQUIRY command to the LUN corresponding to the specified channel:id:lun triplet to verify whether the LUN exists. So a SCSI driver must either take the channel and target id values in account in its quecommand() function or it should declare that it only supports one channel and one target id. Currently the ib_srp driver does neither. As a result scanning the SCSI bus via e.g. rescan-scsi-bus.sh causes many duplicate SCSI devices to be created. For each 0:0:L device, several duplicates are created with the same LUN number and with (C:I) != (0:0). Fix this by declaring that the ib_srp driver only supports one channel and one target id.

commit 93b37905 upstream. Between open(2) of a /dev/fw* and the first FW_CDEV_IOC_GET_INFO ioctl(2) on it, the kernel already queues FW_CDEV_EVENT_BUS_RESET events to be read(2) by the client. The get_info ioctl is practically always issued right away after open, hence this condition only occurs if the client opens during a bus reset, especially during a rapid series of bus resets. The problem with this condition is twofold: - These bus reset events carry the (as yet undocumented) @closure value of 0. But it is not the kernel's place to choose closures; they are privat to the client. E.g., this 0 value forced from the kernel makes it unsafe for clients to dereference it as a pointer to a closure object without NULL pointer check. - It is impossible for clients to determine the relative order of bus reset events from get_info ioctl(2) versus those from read(2), except in one way: By comparison of closure values. Again, such a procedure imposes complexity on clients and reduces freedom in use of the bus reset closure. So, change the ABI to suppress queuing of bus reset events before the first FW_CDEV_IOC_GET_INFO ioctl was issued by the client. Note, this ABI change cannot be version-controlled. The kernel cannot distinguish old from new clients before the first FW_CDEV_IOC_GET_INFO ioctl. We will try to back-merge this change into currently maintained stable/ longterm series, and we only document the new behaviour. The old behavior is now considered a kernel bug, which it basically is. Signed-off-by:

Side note: We return -ENOTTY not only on _IOC_TYPE or _IOC_NR mismatch, but also on _IOC_SIZE mismatch.

commit 67ae7cf1 upstream. Some drivers (ab)use the ethtool_ops::get_regs operation to expose only a hardware revision ID. Commit a77f5db3 ('ethtool: Allocate register dump buffer with vmalloc()') had the side-effect of breaking these, as vmalloc() returns a null pointer for size=0 whereas kmalloc() did not. For backward-compatibility, allow zero-length dumps again. Reported-by:

commit f5bc1e75 upstream. commit fec11dd9 caused a regression when we have already mounted //server/share/a and want to mount //server/share/a/b. The problem is that lookup_one_len calls __lookup_hash with nd pointer as NULL. Then __lookup_hash calls do_revalidate in the case when dentry exists and we end up with NULL pointer deference in cifs_d_revalidate: if (nd->flags & LOOKUP_RCU) return -ECHILD; Fix this by checking nd for NULL.

commit 0472ade0 upstream. Decryping frames on key_miss handling shouldn't be done for Michael MIC failed frames as h/w would have already decrypted such frames successfully anyway. Also leaving CRC and PHY error(where the frame is going to be dropped anyway), we are left to prcoess Decrypt error for which s/w decrypt is selected anway and so having key_miss as a separate check doesn't serve anything. So making key_miss handling mutually exlusive with other RX status handling makes much more sense. This patch addresses an issue with STA not reporting MIC failure events resulting in STA being disconnected immediately. Signed-off-by:

commit 7be4ba24 upstream. Since quite a few drivers are not managing to flag the cache as needing to be resynced after suspend and it's a reasonable thing to do flag the cache as needing sync automatically when suspending. The expectation is that systems will mainly only keep the CODEC powered when doing audio through the CODEC so we won't actually suspend the device anyway; drivers which want to can override this behaviour when they resume.

commit 004c1968 upstream. This patch (as1477) fixes a problem affecting a few types of EHCI controller. Contrary to what one might expect, these controllers automatically stop their internal frame counter when no ports are enabled. Since ehci-hcd currently relies on the frame counter for determining when it should unlink QHs from the async schedule, those controllers run into trouble: The frame counter stops and the QHs never get unlinked. Some systems have also experienced other problems traced back to commit b9638011 (USB: ehci-hcd unlink speedups), which made the original switch from using the system clock to using the frame counter. It never became clear what the reason was for these problems, but evidently it is related to use of the frame counter. To fix all these problems, this patch more or less reverts that commit and goes back to using the system clock. But this can't be done cleanly because other changes have since been made to the scan_async() subroutine. One of these changes involved the tricky logic that tries to avoid rescanning QHs that have already been seen when the scanning loop is restarted, which happens whenever an URB is given back. Switching back to clock-based unlinks would make this logic even more complicated. Therefore the new code doesn't rescan the entire async list whenever a giveback occurs. Instead it rescans only the current QH and continues on from there. This requires the use of a separate pointer to keep track of the next QH to scan, since the current QH may be unlinked while the scanning is in progress. That new pointer must be global, so that it can be adjusted forward whenever the _next_ QH gets unlinked. (uhci-hcd uses this same trick.) Simplification of the scanning loop removes a level of indentation, which accounts for the size of the patch. The amount of code changed is relatively small, and it isn't exactly a reversion of the b9638011 commit. This fixes Bugzilla #32432. Signed-off-by:

commit 6ea12a04 upstream. The NVIDIA series of OHCI controllers continues to be troublesome. A few people using the MCP67 chipset have reported that even with the most recent kernels, the OHCI controller fails to handle new connections and spams the system log with "unable to enumerate USB port" messages. This is different from the other problems previously reported for NVIDIA OHCI controllers, although it is probably related. It turns out that the MCP67 controller does not like to be kept in the RESET state very long. After only a few seconds, it decides not to work any more. This patch (as1479) changes the PCI initialization quirk code so that NVIDIA controllers are switched into the SUSPEND state after 50 ms of RESET. With no interrupts enabled and all the downstream devices reset, and thus unable to send wakeup requests, this should be perfectly safe (even for non-NVIDIA hardware). The removal code in ohci-hcd hasn't been changed; it will still leave the controller in the RESET state. As a result, if someone unloads ohci-hcd and then reloads it, the controller won't work again until the system is rebooted. If anybody complains about this, the removal code can be updated similarly. This fixes Bugzilla #22052. Tested-by:

commit 0c03150e upstream. A bridge topology with three systems: +------+ +------+ | A(2) |--| B(1) | +------+ +------+ \ / +------+ | C(3) | +------+ What is supposed to happen: * bridge with the lowest ID is elected root (for example: B) * C detects that A->C is higher cost path and puts in blocking state What happens. Bridge with lowest id (B) is elected correctly as root and things start out fine initially. But then config BPDU doesn't get transmitted from A -> C. Because of that the link from A-C is transistioned to the forwarding state. The root cause of this is that the configuration messages is generated with bogus message age, and dropped before sending. In the standardmessage_age is supposed to be: the time since the generation of the Configuration BPDU by the Root that instigated the generation of this Configuration BPDU. Reimplement this by recording the timestamp (age + jiffies) when recording config information. The old code incorrectly used the time elapsed on the ageing timer which was incorrect.
