2010-12-15install_special_mapping skips security_file_mmap check.Tavis Ormandy2-4/+17
The install_special_mapping routine (used, for example, to setup the vdso) skips the security check before insert_vm_struct, allowing a local attacker to bypass the mmap_min_addr security restriction by limiting the available pages for special mappings. bprm_mm_init() also skips the check, and although I don't think this can be used to bypass any restrictions, I don't see any reason not to have the security check. $ uname -m x86_64 $ cat /proc/sys/vm/mmap_min_addr 65536 $ cat install_special_mapping.s section .bss resb BSS_SIZE section .text global _start _start: mov eax, __NR_pause int 0x80 $ nasm -D__NR_pause=29 -DBSS_SIZE=0xfffed000 -f elf -o install_special_mapping.o install_special_mapping.s $ ld -m elf_i386 -Ttext=0x10000 -Tbss=0x11000 -o install_special_mapping install_special_mapping.o $ ./install_special_mapping & [1] 14303 $ cat /proc/14303/maps 0000f000-00010000 r-xp 00000000 00:00 0 [vdso] 00010000-00011000 r-xp 00001000 00:19 2453665 /home/taviso/install_special_mapping 00011000-ffffe000 rwxp 00000000 00:00 0 [stack] It's worth noting that Red Hat are shipping with mmap_min_addr set to 4096.

2010-12-14ARM: 6535/1: V6 MPCore v6_dma_inv_range and v6_dma_flush_range RWFO fixValentine Barshak1-8/+20
Cache ownership must be acquired by reading/writing data from the cache line to make cache operation have the desired effect on the SMP MPCore CPU. However, the ownership is never acquired in the v6_dma_inv_range function when cleaning the first line and flushing the last one, in case the address is not aligned to D_CACHE_LINE_SIZE boundary. Fix this by reading/writing data if needed, before performing cache operations. While at it, fix v6_dma_flush_range to prevent RWFO outside the buffer.

2010-12-14ARM: 6534/1: Make CONFIG_FPE_NWFPE depend on !CONFIG_THUMB2_KERNELDave Martin1-1/+1
Because the nwfpe support is unlikely to be used on new platforms and requires CONFIG_OABI_COMPAT, which is not generally used with ARMv7+, we shouldn't expect to build nwfpe support into a Thumb-2 kernel. At present, nwfpe contains assembly code which isn't Thumb-2 compatible, and for now it doesn't appear useful to port this code. All ARMv7-A/R platforms necessarily have VFPv3 hardware floating- point natively, making emulation unnecessary.

2010-12-14ARM: 6533/1: Thumb-2: Make CONFIG_THUMB2_KERNEL depend on !CPU_V6Dave Martin1-1/+1
This makes sense, because Thumb-2 code can't execute on plain ARMv6 processors. This will avoid accidentally configuring a broken kernel where the config otherwise would allow multiple architecture versions to coexist in the same kernel. Not adding !CPU_V5 etc., because the chance of anyone trying to put v5 and v7 in the same kernel is low, and I'm not aware of any mach which can do this. These could be added later if it matters. Note that the rules may need to be refined if support for the ARM1156J(F)-S processor is later added to the kernel, since this processor supports the rare ARMv6T2 extensions, which add support for Thumb-2 and a few other ARMv7 features.

2010-12-14ext4: Turn off multiple page-io submission by defaultTheodore Ts'o3-3/+17
Jon Nelson has found a test case which causes postgresql to fail with the error: psql:t.sql:4: ERROR: invalid page header in block 38269 of relation base/16384/16581 Under memory pressure, it looks like part of a file can end up getting replaced by zero's. Until we can figure out the cause, we'll roll back the change and use block_write_full_page() instead of ext4_bio_write_page(). The new, more efficient writing function can be used via the mount option mblk_io_submit, so we can test and fix the new page I/O code. To reproduce the problem, install postgres 8.4 or 9.0, and pin enough memory such that the system just at the end of triggering writeback before running the following sql script: begin; create temporary table foo as select x as a, ARRAY[x] as b FROM generate_series(1, 10000000 ) AS x; create index foo_a_idx on foo (a); create index foo_b_idx on foo USING GIN (b); rollback; If the temporary table is created on a hard drive partition which is encrypted using dm_crypt, then under memory pressure, approximately 30-40% of the time, pgsql will issue the above failure. This patch should fix this problem, and the problem will come back if the file system is mounted with the mblk_io_submit mount option.

2010-12-14workqueue: It is likely that WORKER_NOT_RUNNING is trueSteven Rostedt1-2/+2
Running the annotate branch profiler on three boxes, including my main box that runs firefox, evolution, xchat, and is part of the distcc farm, showed this with the likelys in the workqueue code: correct incorrect % Function File Line ------- --------- - -------- ---- ---- 96 996253 99 wq_worker_sleeping workqueue.c 703 96 996247 99 wq_worker_waking_up workqueue.c 677 The likely()s in this case were assuming that WORKER_NOT_RUNNING will most likely be false. But this is not the case. The reason is (and shown by adding trace_printks and testing it) that most of the time WORKER_PREP is set. In worker_thread() we have: worker_clr_flags(worker, WORKER_PREP); [ do work stuff ] worker_set_flags(worker, WORKER_PREP, false); (that 'false' means not to wake up an idle worker) The wq_worker_sleeping() is called from schedule when a worker thread is putting itself to sleep. Which happens most of the time outside of that [ do work stuff ]. The wq_worker_waking_up is called by the wakeup worker code, which is also callod outside that [ do work stuff ]. Thus, the likely and unlikely used by those two functions are actually backwards. Remove the annotation and let gcc figure it out.

The commit 111c182340cd22e238ab1cc6564df336c6ebd7cb (kgdboc: reset input devices (keyboards) when exiting debugger) introduced a regression in early debugging such that you get a kernel oops on continue (with the go command) if you boot a kernel with: earlyprintk=vga ekgdboc=kbd kgdbwait The restore kgdboc_restore_input() routine schedules work for the purpose of sending key release events for any keys that were in the depressed state prior to entering the kernel debugger.

2010-12-14Btrfs: prevent RAID level downgrades when space is lowChris Mason1-1/+19
The extent allocator has code that allows us to fill allocations from any available block group, even if it doesn't match the raid level we've requested. This was put in because adding a new drive to a filesystem made with the default mkfs options actually upgrades the metadata from single spindle dup to full RAID1. But, the code also allows us to allocate from a raid0 chunk when we really want a raid1 or raid10 chunk. This can cause big trouble because mkfs creates a small (4MB) raid0 chunk for data and metadata which then goes unused for raid1/raid10 installs. The allocator will happily wander in and allocate from that chunk when things get tight, which is not correct. The fix here is to make sure that we provide duplication when the caller has asked for it. It does all the dups to be any raid level, which preserves the dup->raid1 upgrade abilities.

2010-12-14Btrfs: account for missing devices in RAID allocation profilesChris Mason3-3/+36
When we mount in RAID degraded mode without adding a new device to replace the failed one, we can end up using the wrong RAID flags for allocations. This results in strange combinations of block groups (raid1 in a raid10 filesystem) and corruptions when we try to allocate blocks from single spindle chunks on drives that are actually missing. The first device has two small 4MB chunks in it that mkfs creates and these are usually unused in a raid1 or raid10 setup. But, in -o degraded, the allocator will fall back to these because the mask of desired raid groups isn't correct. The fix here is to count the missing devices as we build up the list of devices in the system. This count is used when picking the raid level to make sure we continue using the same levels that were in place before we lost a drive. Signed-off-by: Chris Mason <chris.mason@oracle.com>

The current implementation of the v7_coherent_*_range function assumes that the D and I cache lines have the same size, which is incorrect architecturally. This patch adds the icache_line_size macro which reads the CTR register. The main loop in v7_coherent_*_range is split in two independent loops or the D and I caches.

2010-12-11acpi: fix _OSI string setup regressionLin Ming2-27/+34
commit b0ed7a91(ACPICA/ACPI: Add new host interfaces for _OSI suppor) introduced a regression that _OSI string setup fails. There are 2 paths to setup _OSI string. DMI: acpi_dmi_osi_linux -> set_osi_linux -> acpi_osi_setup -> copy _OSI string to osi_setup_string Boot command line: acpi_osi_setup -> copy _OSI string to osi_setup_string Later, acpi_osi_setup_late will be called to handle osi_setup_string. If _OSI string is "Linux" or "!Linux", then the call path is, acpi_osi_setup_late -> acpi_cmdline_osi_linux -> set_osi_linux -> acpi_osi_setup -> copy _OSI string to osi_setup_string This actually never installs _OSI string(acpi_install_interface not called), but just copy the _OSI string to osi_setup_string. This patch fixes the regression. Reported-and-tested-by: Lukas Hejtmanek <xhejtman@ics.muni.cz> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-12-11OMAP2: PRCM: fix some SHIFT macros that were actually bitmasksPaul Walmsley1-5/+6
After Charu's GPIO hwmod patches, GPIO initialization on N800 emits the following messages for all GPIO banks: omap_hwmod: gpio1: cannot be enabled (3) This is due to OMAP24XX_ST_GPIOS_SHIFT being defined as a bitmask. Fix this and also fix two other macros that had the same problem. Thanks to Tony Lindgren <tony@atomide.com> for originally reporting this bug.

Was using L1_CACHE_BYTES for the Ingress Queue Entry Size but it really needs to be 64 bytes in order to support the largest message sizes. Signed-off-by: Casey Leedom <leedom@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-12-11phy: add the IC+ IP1001 driverGiuseppe CAVALLARO2-6/+55
This patch adds the IC+ IP1001 (Gigabit Ethernet Transceiver) driver. I've had to add an additional delay (2ns) to adjust RX clock phase at GMII/ RGMII interface (according to the PHY data-sheet). This helps to have the RGMII working on some ST platforms. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S. Miller <davem@davemloft.net>
