2009-06-06ext3/4 with synchronous writes gets wedged by PostfixAl Viro
OK, that's probably the easiest way to do that, as much as I don't like it... Since iget() et.al. will not accept I_FREEING (will wait to go away and restart), and since we'd better have serialization between new/free on fs data structures anyway, we can afford simply skipping I_FREEING et.al. in insert_inode_locked(). We do that from new_inode, so it won't race with free_inode in any interesting ways and it won't race with iget (of any origin; nfsd or in case of fs corruption a lookup) since both still will wait for I_LOCK.

2009-06-06Fix nobh_truncate_page() to not pass stack garbage to get_block()Theodore Ts'o
The nobh_truncate_page() function is used by ext2, exofs, and jfs. Of these three, only ext2 and jfs's get_block() function pays attention to bh->b_size --- which is normally always the filesystem blocksize except when the get_block() function is called by either mpage_readpage(), mpage_readpages(), or the direct I/O routines in fs/direct_io.c. Unfortunately, nobh_truncate_page() does not initialize map_bh before calling the filesystem-supplied get_block() function. So ext2 and jfs will try to calculate the number of blocks to map by taking stack garbage and shifting it left by inode->i_blkbits. This should be *mostly* harmless (except the filesystem will do some unnneeded work) unless the stack garbage is less than filesystem's blocksize, in which case maxblocks will be zero, and the attempt to find out whether or not the filesystem has a hole at a given logical block will fail, and the page cache entry might not get zero'ed out. Also if the stack garbage in in map_bh->state happens to have the BH_Mapped bit set, there could be an attempt to call readpage() on a non-existent page, which could cause nobh_truncate_page() to return an error when it should not. Fix this by initializing map_bh->state and map_bh->size. Fortunately, it's probably fairly unlikely that ext2 and jfs users mount with nobh these days.

2009-06-05pata_legacy: wait for async probingJames Bottomley
The basic problem here that pata_legacy attaches the host, sees if it found any devices and detaches it if none were found. With async probing, it's not waiting until discovery is finished before deciding it has no devices and trying the detach leading to this warning: ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14 ------------[ cut here ]------------ WARNING: at drivers/ata/libata-core.c:6222 ata_host_detach+0x75/0x90() Modules linked in: Pid: 1, comm: swapper Not tainted 2.6.30-rc7 #1 Call Trace: [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c01139b5>] ? warn_slowpath_common+0x45/0x80 [<c01139fa>] ? warn_slowpath_null+0xa/0x10 [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c02f40e0>] ? legacy_init+0x44e/0x87f [<c02f3c92>] ? legacy_init+0x0/0x87f [<c0101021>] ? _stext+0x21/0x140 [<c01890ff>] ? proc_register+0x2f/0x190 [<c018938c>] ? create_proc_entry+0x5c/0xc0 [<c0135ebe>] ? register_irq_proc+0x6e/0x90 [<c02e6484>] ? kernel_init+0x6e/0xbf [<c02e6416>] ? kernel_init+0x0/0xbf [<c01031d7>] ? kernel_thread_helper+0x7/0x10 ---[ end trace ef1ee36e873ae3a0 ]--- Because it detaches before the probe is complete.

2009-06-04ptrace: revert "ptrace_detach: the wrong wakeup breaks the ERESTARTxxx logic"Oleg Nesterov
Commit 95a3540da9c81a5987be810e1d9a83640a366bd5 ("ptrace_detach: the wrong wakeup breaks the ERESTARTxxx logic") removed the "extra" wake_up_process() from ptrace_detach(), but as Jan pointed out this breaks the compatibility. I believe the changelog is right and this wake_up() is wrong in many ways, but GDB assumes that ptrace(PTRACE_DETACH, child, 0, 0) always wakes up the tracee. Despite the fact this breaks SIGNAL_STOP_STOPPED/group_stop_count logic, and despite the fact this wake_up_process() can break another assumption: PTRACE_DETACH with SIGSTOP should leave the tracee in TASK_STOPPED case. Because the untraced child can dequeue SIGSTOP and call do_signal_stop() before ptrace_detach() calls wake_up_process(). Revert this change for now. We need some fixes even if we we want to keep the current behaviour, but these fixes are not for 2.6.30.

2009-06-04ptrace: tracehook_report_clone: fix false positivesOleg Nesterov
The "trace || CLONE_PTRACE" check in tracehook_report_clone() is not right, - If the untraced task does clone(CLONE_PTRACE) the new child is not traced, we must not queue SIGSTOP. - If we forked the traced task, but the tracer exits and untraces both the forking task and the new child (after copy_process() drops tasklist_lock), we should not queue SIGSTOP too. Change the code to check task_ptrace() != 0 instead. This is still racy, but the race is harmless. We can race with another tracer attaching to this child, or the tracer can exit and detach in parallel. But giwen that we didn't do wake_up_new_task() yet, the child must have the pending SIGSTOP anyway.

2009-06-04drivers/char/mem.c: avoid OOM lockup during large reads from /dev/zeroSalman Qazi
While running 20 parallel instances of dd as follows: #!/bin/bash for i in `seq 1 20`; do dd if=/dev/zero of=/export/hda3/dd_$i bs=1073741824 count=1 & done wait on a 16G machine, we noticed that rather than just killing the processes, the entire kernel went down. Stracing dd reveals that it first does an mmap2, which makes 1GB worth of zero page mappings. Then it performs a read on those pages from /dev/zero, and finally it performs a write. The machine died during the reads. Looking at the code, it was noticed that /dev/zero's read operation had been changed by 557ed1fa2620dc119adb86b34c614e152a629a80 ("remove ZERO_PAGE") from giving zero page mappings to actually zeroing the page. The zeroing of the pages causes physical pages to be allocated to the process. But, when the process exhausts all the memory that it can, the kernel cannot kill it, as it is still in the kernel mode allocating more memory. Consequently, the kernel eventually crashes. To fix this, I propose that when a fatal signal is pending during /dev/zero read operation, we simply return and let the user process die.

2009-06-04Btrfs: Fix oops and use after free during space balancingChris Mason
The btrfs allocator uses list_for_each to walk the available block groups when searching for free blocks. It starts off with a hint to help find the best block group for a given allocation. The hint is resolved into a block group, but we don't properly check to make sure the block group we find isn't in the middle of being freed due to filesystem shrinking or balancing. If it is being freed, the list pointers in it are bogus and can't be trusted. But, the code happily goes along and uses them in the list_for_each loop, leading to all kinds of fun. The fix used here is to check to make sure the block group we find really is on the list before we use it. list_del_init is used when removing it from the list, so we can do a proper check. The allocation clustering code has a similar bug where it will trust the block group in the current free space cluster. If our allocation flags have changed (going from single spindle dup to raid1 for example) because the drives in the FS have changed, we're not allowed to use the old block group any more. The fix used here is to check the current cluster against the current allocation flags. Signed-off-by: Chris Mason <chris.mason@oracle.com>

drm_helper_connector_dpms. Making the drm_crtc.c code recognize the DPMS property and invoke the connector->dpms function doesn't remove any capability from the driver while reducing code duplication. That just highlighted the problem with the existing DPMS functions which could turn off the connector, but failed to turn off any relevant crtcs. The new drm_helper_connector_dpms function manages all of that, using the drm_helper-specific crtc and encoder dpms functions, automatically computing the appropriate DPMS level for each object in the system. This fixes the current troubles in the i915 driver which left PLLs, pipes and planes running while in DPMS_OFF mode or even while they were unused.

2009-06-03mvsdio: fix config failure with some high speed SDHC cardsNicolas Pitre
Especially with Sandisk SDHC cards, the second SWITCH command was failing with a timeout and the card was not recognized at all. However if the system was busy, or debugging was enabled, or a udelay(100) was inserted before the second SWITCH command in the core code, then the timing was so that the card started to work. With some unusual block sizes, the data FIFO status doesn't indicate a "empty" state right away when the data transfer is done. Queuing another data transfer in that condition results in a transfer timeout. The empty FIFO bit eventually get set by itself in less than 50 usecs when it is not set right away.

This replaces the dangerous instances with the _nosync() variant which doesn't have this problem.
