27cf3a1 Linus Torvalds 22 April 2015, 21:49:23 UTC Merge branch 'upstream' of git://git.infradead.org/users/pcmoore/audit Pull audit fixes from Paul Moore: "Seven audit patches for v4.1, all bug fixes. The largest, and perhaps most significant commit helps resolve some memory pressure issues related to the inode cache and audit, there are also a few small commits which help resolve some timing issues with the audit log queue, and the rest fall into the always popular "code clean-up" category. In general, nothing really substantial, just a nice set of maintenance patches" * 'upstream' of git://git.infradead.org/users/pcmoore/audit: audit: Remove condition which always evaluates to false audit: reduce mmap_sem hold for mm->exe_file audit: consolidate handling of mm->exe_file audit: code clean up audit: don't reset working wait time accidentally with auditd audit: don't lose set wait time on first successful call to audit_log_start() audit: move the tree pruning to a dedicated thread 22 April 2015, 21:49:23 UTC
a62d016 Linus Torvalds 22 April 2015, 19:00:44 UTC Merge tag 'for-linus-20150422' of git://git.infradead.org/linux-mtd Pull MTD updates from Brian Norris: "Common MTD: - Add Kconfig option for keeping both the 'master' and 'partition' MTDs registered as devices. This would really make a better default if we could do it over, as it allows a lot more flexibility in (1) determining the flash topology of the system from user-space and (2) adding temporary partitions at runtime (ioctl(BLKPG)). Unfortunately, this would possibly cause user-space breakage, as it will cause renumbering of the /dev/mtdX devices. We'll see if we can change this in the future, as there have already been a few people looking for this feature, and I know others have just been working around our current limitations instead of fixing them this way. - Along with the previous change, add some additional information to sysfs, so user-space can read the offset of each partition within its master device SPI NOR: - add new device tree compatible binding to represent the mostly-compatible class of SPI NOR flash which can be detected by their extended JEDEC ID bytes, cutting down the duplication of our ID tables - misc. new IDs Various other miscellaneous fixes and changes" * tag 'for-linus-20150422' of git://git.infradead.org/linux-mtd: (53 commits) mtd: spi-nor: Add support for Macronix mx25u6435f serial flash mtd: spi-nor: Add support for Winbond w25q64dw serial flash mtd: spi-nor: add support for the Winbond W25X05 flash mtd: spi-nor: support en25s64 device mtd: m25p80: bind to "nor-jedec" ID, for auto-detection Documentation: devicetree: m25p80: add "nor-jedec" binding mtd: Make MTD tests cancelable mtd: mtd_oobtest: Fix bitflip_limit usage in test case 3 mtd: docg3: remove invalid __exit annotations mtd: fsl_ifc_nand: use msecs_to_jiffies for time conversion mtd: atmel_nand: don't map the ROM table if no pmecc table offset in DT mtd: atmel_nand: add a definition for the oob reserved bytes mtd: part: Remove partition overlap checks mtd: part: Add sysfs variable for offset of partition mtd: part: Create the master device node when partitioned mtd: ts5500_flash: Fix typo in MODULE_DESCRIPTION in ts5500_flash.c mtd: denali: Disable sub-page writes in Denali NAND driver mtd: pxa3xx_nand: cleanup wait_for_completion handling mtd: nand: gpmi: Check for scan_bbt() error mtd: nand: gpmi: fixup return type of wait_for_completion_timeout ... 22 April 2015, 19:00:44 UTC

The first is a bug when ftrace_dump_on_oops is triggered in atomic context and function graph tracer is the tracer that is being reported. The second fix is bad parsing of the trace_events from the kernel command line, where it would ignore specific events if the system name is used with defining the event(it enables all events within the system). The last one is a fix to the TRACE_DEFINE_ENUM(), where a check was missing to see if the ptr was incremented to the end of the string, but the loop increments it again and can miss the nul delimiter to stop processing" * tag 'trace-v4.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix possible out of bounds memory access when parsing enums tracing: Fix incorrect enabling of trace events by boot cmdline tracing: Handle ftrace_dump() atomic context in graph_trace_open() 22 April 2015, 18:27:36 UTC

958a276 Ilya Dryomov 14 April 2015, 13:54:52 UTC crush: straw2 bucket type with an efficient 64-bit crush_ln() This is an improved straw bucket that correctly avoids any data movement between items A and B when neither A nor B's weights are changed. Said differently, if we adjust the weight of item C (including adding it anew or removing it completely), we will only see inputs move to or from C, never between other items in the bucket. Notably, there is not intermediate scaling factor that needs to be calculated. The mapping function is a simple function of the item weights. The below commits were squashed together into this one (mostly to avoid adding and then yanking a ~6000 lines worth of crush_ln_table): - crush: add a straw2 bucket type - crush: add crush_ln to calculate nature log efficently - crush: improve straw2 adjustment slightly - crush: change crush_ln to provide 32 more digits - crush: fix crush_get_bucket_item_weight and bucket destroy for straw2 - crush/mapper: fix divide-by-0 in straw2 (with div64_s64() for draw = ln / w and INT64_MIN -> S64_MIN - need to create a proper compat.h in ceph.git) Reflects ceph.git commits 242293c908e923d474910f2b8203fa3b41eb5a53, 32a1ead92efcd351822d22a5fc37d159c65c1338, 6289912418c4a3597a11778bcf29ed5415117ad9, 35fcb04e2945717cf5cfe150b9fa89cb3d2303a1, 6445d9ee7290938de1e4ee9563912a6ab6d8ee5f, b5921d55d16796e12d66ad2c4add7305f9ce2353.

9fbbda5 Bjorn Helgaas 21 April 2015, 19:57:26 UTC ia64/PCI: Treat all host bridge Address Space Descriptors (even consumers) as windows Prior to c770cb4cb505 ("PCI: Mark invalid BARs as unassigned"), if we tried to claim a PCI BAR but could not find an upstream bridge window that matched it, we complained but still allowed the device to be enabled. c770cb4cb505 broke devices that previously worked (mptsas and igb in the case Tony reported, but it could be any devices) because it marks those BARs as IORESOURCE_UNSET, which makes pci_enable_device() complain and return failure: igb 0000:81:00.0: can't enable device: BAR 0 [mem size 0x00020000] not assigned igb: probe of 0000:81:00.0 failed with error -22 The underlying cause is an ACPI Address Space Descriptor for a PCI host bridge window that is marked as "consumer". This is a firmware defect: resources that are produced on the downstream side of a bridge should be marked "producer". But rejecting these BARs that we previously allowed is a functionality regression, and firmware has not used the producer/consumer bit consistently, so we can't rely on it anyway. Stop checking the producer/consumer bit, and assume all bridge Address Space Descriptors are for bridge windows. Note that this change does not affect I/O Port or Fixed Location I/O Port Descriptors, which are commonly used for the [io 0x0cf8-0x0cff] config access range. That range is a "consumer" range and should not be treated as a window.

8f443e2 Linus Torvalds 21 April 2015, 16:17:28 UTC Revert "ocfs2: incorrect check for debugfs returns" This reverts commit e2ac55b6a8e337fac7cc59c6f452caac92ab5ee6. Huang Ying reports that this causes a hang at boot with debugfs disabled. It is true that the debugfs error checks are kind of confusing, and this code certainly merits more cleanup and thinking about it, but there's something wrong with the trivial "check not just for NULL, but for error pointers too" patch. Yes, with debugfs disabled, we will end up setting the o2hb_debug_dir pointer variable to an error pointer (-ENODEV), and then continue as if everything was fine. But since debugfs is disabled, all the _users_ of that pointer end up being compiled away, so even though the pointer can not be dereferenced, that's still fine. So it's confusing and somewhat questionable, but the "more correct" error checks end up causing more trouble than they fix.

In SGMII configurations this leads to error-symbols on the PCS and packet-rejection on the receiver side (e.g. SGMII/1000Base-X connected switch). This only applies to the tse-configuration with MSGDMA. This issue was detected and fixed on a custom board with a direct connection to a Marvell switch in SGMII-PHY-Mode. (incl. custom patches for SGMII-PCS). According to the datasheet if ff_tx_err (avalon-streaming) is set it is forwarded to gm_tx_err.

91f5bd8 David S. Miller 21 April 2015, 01:57:26 UTC Merge branch 'ppp_csum_unset' Tom Herbert says: ==================== net: Fix "hw csum failure" message flood for ppp tunnel This patch set addresses bug "Bug 95171 - "hw csum failure" message flood for ppp tunnel since upgrade to 3.16". The problem is that pppoe is being used over UDP with UDP checksusm enabled. On receive checksum conversion turns checksum-unnecessary in checksum- complete. The PPP receive functions do not properly pull the checksum over its headers, so that when an encapsulated checksums is considered the checksum-complete value is incorrect. This patch adds skb_checksum_complete_unset which can be called in the receive path in lieu of pulling checksum complete in layer. This is useful when the packet is being modified (e.g. decompressed) and the checksum-complete value is no longer relevant. In the ppp_receive_frame we call skb_checksum_complete_unset to toss out checksum-complete. This should eliminate the reported messages. Alternatively, we could add skb_postpull_rcsum and probably special case handling for VJ compression if maintaining the checksum-complete is needed (not clear to me this is worth the effort). I haven't tested this since setting up the failure scenario doesn't seem trivial to configure. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> 21 April 2015, 01:57:26 UTC

Especially tw sockets will lead to panics later-on in the stack. This was observed with TPROXY assigning a tw socket and broken policy routing (misconfigured). As a result frame enters forwarding path instead of input.

f4d03bd Linus Torvalds 20 April 2015, 16:08:49 UTC smp: don't use 16-bit words for atomic accesses Yes, it should work, but it's a bad idea. Not only did ARM64 not have the 16-bit access code (there's a separate patch to add it), it's just not a good atomic type. Some architectures fundamentally don't do atomic accesses in them (alpha), and it's not like it saves any space here anyway because of structure packing issues. We normally should aim for flags to be "unsigned int" or "unsigned long". And if space is at a premium, use a single byte (although that causes problems on alpha again). There might be very special cases where a 16-byte entity is really wanted, but this is not one of them. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 20 April 2015, 16:08:49 UTC
