2010-12-16MIPS: Separate two consecutive loads in memset.STony Wu1-2/+2
partial_fixup is used in noreorder block. Separating two consecutive loads can save one cycle on processors with GPR intrelock and can fix load-use on processors that need a load delay slot. Also do so for fwd_fixup. [Ralf: Only R2000/R3000 class processors are lacking the the load-user interlock and even some of those got it retrofitted. With R2000/R3000 being fairly uncommon these days the impact of this bug should be minor.] Signed-off-by: Tony Wu <[email protected]> To: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/1768/ Signed-off-by: Ralf Baechle <[email protected]>
2010-12-16MIPS: Send proper signal and siginfo on FP emulator faults.David Daney2-30/+130
We were unconditionally sending SIGBUS with an empty siginfo on FP emulator faults. This differs from what happens when real floating point hardware would get a fault. For most faults we need to send SIGSEGV with the faulting address filled in in the struct siginfo.

2010-12-16PM / Runtime: Fix pm_runtime_suspended()Rafael J. Wysocki2-3/+4
There are some situations (e.g. in __pm_generic_call()), where pm_runtime_suspended() is used to decide whether or not to execute a device's (system) ->suspend() callback. The callback is not executed if pm_runtime_suspended() returns true, but it does so for devices that don't even support runtime PM, because the power.disable_depth device field is ignored by it. This leads to problems (i.e. devices are not suspened when they should), so rework pm_runtime_suspended() so that it returns false if the device's power.disable_depth field is different from zero.

2010-12-16PM / Hibernate: Restore old swap signature to avoid user space breakageRafael J. Wysocki1-1/+1
Commit 3624eb0 (PM / Hibernate: Modify signature used to mark swap) attempted to modify hibernate signature used to mark swap partitions containing hibernation images, so that old kernels don't try to handle compressed images. However, this change broke resume from hibernation on Fedora 14 that apparently doesn't pass the resume= argument to the kernel and tries to trigger resume from early user space. This doesn't work, because the signature is now different, so the old signature has to be restored to avoid the problem. Addresses https://bugzilla.kernel.org/show_bug.cgi?id=22732 .

2010-12-16sched: Fix the irqtime code for 32bitPeter Zijlstra1-6/+45
Since the irqtime accounting is using non-atomic u64 and can be read from remote cpus (writes are strictly cpu local, reads are not) we have to deal with observing partial updates. When we do observe partial updates the clock movement (in particular, ->clock_task movement) will go funny (in either direction), a subsequent clock update (observing the full update) will make it go funny in the oposite direction. Since we rely on these clocks to be strictly monotonic we cannot suffer backwards motion. One possible solution would be to simply ignore all backwards deltas, but that will lead to accounting artefacts, most notable: clock_task + irq_time != clock, this inaccuracy would end up in user visible stats. Therefore serialize the reads using a seqcount.

Some ARM systems have a short sched_clock() [ which needs to be fixed too ], but this exposed a bug in the irq_time code as well, it doesn't deal with wraps at all.

2010-12-16lguest: populate initial_page_tableRusty Russell3-5/+107
Two x86 patches broke lguest: 1) v2.6.35-492-g72d7c3b, which changed x86 to use the memblock allocator. In lguest, the host places linear page tables at the top of mem, which used to be enough to get us up to the swapper_pg_dir page tables. With the first patch, the direct mapping tables used that memory: Before: kernel direct mapping tables up to 4000000 @ 7000-1a000 After: kernel direct mapping tables up to 4000000 @ 3fed000-4000000 I initially fixed this by lying about the amount of memory we had, so the kernel wouldn't blatt the lguest boot pagetables (yuk!), but then... 2) v2.6.36-rc8-54-gb40827f, which made x86 boot use initial_page_table. This was initialized in a part of head_32.S which isn't executed by lguest; it is then copied into swapper_pg_dir. So we have to initialize it; and anyway we switch to it before we blatt the old tables, so that fixes the previous damage as well. For the moment, I cut & pasted the code into lguest's boot code, but next merge window I will merge them.

2010-12-16lguest: restore boot speedRusty Russell1-4/+7
lguest is dumb and drops *all* the pagetables for set_pte (which is only used for kernel mapping manipulation, so it's OK without highmem). But it's used a lot in boot, too. As a guest optimization, we suppressed this flushing until the first page switch. Now we have initial_page_table, that happens much earlier, so extend the heuristic to wait until we switch to something other than the swapper_pg_dir or initial_page_table. As measured on my laptop under kvm, this dropped the time-to-mount-root from 48 seconds to 4.3 seconds. Signed-off-by: Rusty Russell <[email protected]>

2010-12-16nilfs2: fix regression of garbage collection ioctlRyusuke Konishi2-9/+12
On 2.6.37-rc1, garbage collection ioctl of nilfs was broken due to the commit 263d90cefc7d82a0 ("nilfs2: remove own inode hash used for GC"), and leading to filesystem corruption. The patch doesn't queue gc-inodes for log writer if they are reused through the vfs inode cache. Here, gc-inode is the inode which buffers blocks to be relocated on GC. That patch queues gc-inodes in nilfs_init_gcinode() function, but this function is not called when they don't have I_NEW flag. Thus, some of live blocks are wrongly overrode without being moved to new logs. This resolves the problem by moving the gc-inode queueing to an outer function to ensure it's done right.

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.
