[PATCH] x86_64: GART DMA merging fix

2006-02-13T00:10:47+00:00

Don't touch the non DMA members in the sg list in dma_map_sg in the IOMMU Some drivers (in particular ST) ran into problems because they reused the sg lists after passing them to pci_map_sg(). The merging procedure in the K8 GART IOMMU corrupted the state. This patch changes it to only touch the dma* entries during merging, but not the other fields. Approach suggested by Dave Miller.

[PATCH] arch/x86_64/kernel/traps.c PTRACE_SINGLESTEP oops

2006-02-13T00:10:47+00:00

We found a problem with x86_64 kernels with preemption enabled, where having multiple tasks doing ptrace singlesteps around the same time will cause the system to 'oops'. The problem seems that a task can get preempted out of the do_debug() processing while it is running on the DEBUG_STACK stack. If another task on that same cpu then enters do_debug() and uses the same per-cpu DEBUG_STACK stack, the previous preempted tasks's stack contents can be corrupted, and the system will oops when the preempted task is context switched back in again. The typical oops looks like the following: Unable to handle kernel paging request at ffffffffffffffae RIP: {thread_return+34} PGD 103027 PUD 102429067 PMD 0 Oops: 0002 [1] PREEMPT SMP CPU 0 Modules linked in: Pid: 3786, comm: ssdd Not tainted 2.6.15.2 #1 RIP: 0010:[] {thread_return+34} RSP: 0018:ffffffff80824058 EFLAGS: 000136c2 RAX: ffff81017e12cea0 RBX: 0000000000000000 RCX: 00000000c0000100 RDX: 0000000000000000 RSI: ffff8100f7856e20 RDI: ffff81017e12cea0 RBP: 0000000000000046 R08: ffff8100f68a6000 R09: 0000000000000000 R10: 0000000000000000 R11: ffff81017e12cea0 R12: ffff81000c2d53e8 R13: ffff81017f5b3be8 R14: ffff81000c0036e0 R15: 000001056cbfc899 FS: 00002aaaaaad9b00(0000) GS:ffffffff80883800(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffffffffffffffae CR3: 00000000f6fcf000 CR4: 00000000000006e0 Process ssdd (pid: 3786, threadinfo ffff8100f68a6000, task ffff8100f7856e20) Stack: ffffffff808240d8 ffffffff8012a84a ffff8100055f6c00 0000000000000020 0000000000000001 ffff81000c0036e0 ffffffff808240b8 0000000000000000 0000000000000000 0000000000000000 Call Trace: <#DB> {try_to_wake_up+985} {kick_process+87} {signal_wake_up+48} {specific_send_sig_info+179} {_spin_unlock_irqrestore+27} {force_sig_info+159} {do_debug+289} {sync_regs+103} {paranoid_userspace+35} Unable to handle kernel paging request at 00007fffffb7d000 RIP: {show_trace+465} PGD f6f25067 PUD f6fcc067 PMD f6957067 PTE 0 Oops: 0000 [2] PREEMPT SMP This patch disables preemptions for the task upon entry to do_debug(), before interrupts are reenabled, and then disables preemption before exiting do_debug(), after disabling interrupts. I've noticed that the task can be preempted either at the end of an interrupt, or on the call to force_sig_info() on the spin_unlock_irqrestore() processing. It might be better to attempt to code a fix in entry.S around the code that calls do_debug(). Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] reiserfs: disable automatic enabling of reiserfs inode attributes

2006-02-13T00:10:47+00:00

Unfortunately, the reiserfs_attrs_cleared bit in the superblock flag can lie. File systems have been observed with the bit set, yet still contain garbage in the stat data field, causing unpredictable results. This patch backs out the enable-by-default behavior. It eliminates the changes from: d50a5cd860ce721dbeac6a4f3c6e42abcde68cd8, and ef5e5414e7a83eb9b4295bbaba5464410b11e030.
