When an hfsplus image gets corrupted it might happen that the catalog namelength field gets b0rked. If we mount such an image the memcpy() in hfsplus_cat_build_key_uni() writes more than the 255 that fit in the name field. Depending on the size of the overwritten data, we either only get memory corruption or also trigger an oops like this: [ 221.628020] BUG: unable to handle kernel paging request at c82b0000 [ 221.629066] IP: [<c022d4b1>] hfsplus_find_cat+0x10d/0x151 [ 221.629066] *pde = 0ea29163 *pte = 082b0160 [ 221.629066] Oops: 0002 [#1] PREEMPT DEBUG_PAGEALLOC [ 221.629066] Modules linked in: [ 221.629066] [ 221.629066] Pid: 4845, comm: mount Not tainted (2.6.27-rc4-00123-gd3ee1b40-dirty #28) [ 221.629066] EIP: 0060:[<c022d4b1>] EFLAGS: 00010206 CPU: 0 [ 221.629066] EIP is at hfsplus_find_cat+0x10d/0x151 [ 221.629066] EAX: 00000029 EBX: 00016210 ECX: 000042c2 EDX: 00000002 [ 221.629066] ESI: c82d70ca EDI: c82b0000 EBP: c82d1bcc ESP: c82d199c [ 221.629066] DS: 007b ES: 007b FS: 0000 GS: 0033 SS: 0068 [ 221.629066] Process mount (pid: 4845, ti=c82d1000 task=c8224060 task.ti=c82d1000) [ 221.629066] Stack: c080b3c4 c82aa8f8 c82d19c2 00016210 c080b3be c82d1bd4 c82aa8f0 00000300 [ 221.629066] 01000000 750008b1 74006e00 74006900 65006c00 c82d6400 c013bd35 c8224060 [ 221.629066] 00000036 00000046 c82d19f0 00000082 c8224548 c8224060 00000036 c0d653cc [ 221.629066] Call Trace: [ 221.629066] [<c013bd35>] ? trace_hardirqs_off+0xb/0xd [ 221.629066] [<c013bca3>] ? trace_hardirqs_off_caller+0x14/0x9b [ 221.629066] [<c013bd35>] ? trace_hardirqs_off+0xb/0xd [ 221.629066] [<c013bca3>] ? trace_hardirqs_off_caller+0x14/0x9b [ 221.629066] [<c013bd35>] ? trace_hardirqs_off+0xb/0xd [ 221.629066] [<c0107aa3>] ? native_sched_clock+0x82/0x96 [ 221.629066] [<c01302d2>] ? __kernel_text_address+0x1b/0x27 [ 221.629066] [<c010487a>] ? dump_trace+0xca/0xd6 [ 221.629066] [<c0109e32>] ? save_stack_address+0x0/0x2c [ 221.629066] [<c0109eaf>] ? save_stack_trace+0x1c/0x3a [ 221.629066] [<c013b571>] ? save_trace+0x37/0x8d [ 221.629066] [<c013b62e>] ? add_lock_to_list+0x67/0x8d [ 221.629066] [<c013ea1c>] ? validate_chain+0x8a4/0x9f4 [ 221.629066] [<c013553d>] ? down+0xc/0x2f [ 221.629066] [<c013f1f6>] ? __lock_acquire+0x68a/0x6e0 [ 221.629066] [<c013bd35>] ? trace_hardirqs_off+0xb/0xd [ 221.629066] [<c013bca3>] ? trace_hardirqs_off_caller+0x14/0x9b [ 221.629066] [<c013bd35>] ? trace_hardirqs_off+0xb/0xd [ 221.629066] [<c0107aa3>] ? native_sched_clock+0x82/0x96 [ 221.629066] [<c013da5d>] ? mark_held_locks+0x43/0x5a [ 221.629066] [<c013dc3a>] ? trace_hardirqs_on+0xb/0xd [ 221.629066] [<c013dbf4>] ? trace_hardirqs_on_caller+0xf4/0x12f [ 221.629066] [<c06abec8>] ? _spin_unlock_irqrestore+0x42/0x58 [ 221.629066] [<c013555c>] ? down+0x2b/0x2f [ 221.629066] [<c022aa68>] ? hfsplus_iget+0xa0/0x154 [ 221.629066] [<c022b0b9>] ? hfsplus_fill_super+0x280/0x447 [ 221.629066] [<c0107aa3>] ? native_sched_clock+0x82/0x96 [ 221.629066] [<c013bca3>] ? trace_hardirqs_off_caller+0x14/0x9b [ 221.629066] [<c013bca3>] ? trace_hardirqs_off_caller+0x14/0x9b [ 221.629066] [<c013f1f6>] ? __lock_acquire+0x68a/0x6e0 [ 221.629066] [<c041c9e4>] ? string+0x2b/0x74 [ 221.629066] [<c041cd16>] ? vsnprintf+0x2e9/0x512 [ 221.629066] [<c010487a>] ? dump_trace+0xca/0xd6 [ 221.629066] [<c0109eaf>] ? save_stack_trace+0x1c/0x3a [ 221.629066] [<c0109eaf>] ? save_stack_trace+0x1c/0x3a [ 221.629066] [<c013b571>] ? save_trace+0x37/0x8d [ 221.629066] [<c013b62e>] ? add_lock_to_list+0x67/0x8d [ 221.629066] [<c013ea1c>] ? validate_chain+0x8a4/0x9f4 [ 221.629066] [<c01354d3>] ? up+0xc/0x2f [ 221.629066] [<c013f1f6>] ? __lock_acquire+0x68a/0x6e0 [ 221.629066] [<c013bd35>] ? trace_hardirqs_off+0xb/0xd [ 221.629066] [<c013bca3>] ? trace_hardirqs_off_caller+0x14/0x9b [ 221.629066] [<c013bd35>] ? trace_hardirqs_off+0xb/0xd [ 221.629066] [<c0107aa3>] ? native_sched_clock+0x82/0x96 [ 221.629066] [<c041cfb7>] ? snprintf+0x1b/0x1d [ 221.629066] [<c01ba466>] ? disk_name+0x25/0x67 [ 221.629066] [<c0183960>] ? get_sb_bdev+0xcd/0x10b [ 221.629066] [<c016ad92>] ? kstrdup+0x2a/0x4c [ 221.629066] [<c022a7b3>] ? hfsplus_get_sb+0x13/0x15 [ 221.629066] [<c022ae39>] ? hfsplus_fill_super+0x0/0x447 [ 221.629066] [<c0183583>] ? vfs_kern_mount+0x3b/0x76 [ 221.629066] [<c0183602>] ? do_kern_mount+0x32/0xba [ 221.629066] [<c01960d4>] ? do_new_mount+0x46/0x74 [ 221.629066] [<c0196277>] ? do_mount+0x175/0x193 [ 221.629066] [<c013dbf4>] ? trace_hardirqs_on_caller+0xf4/0x12f [ 221.629066] [<c01663b2>] ? __get_free_pages+0x1e/0x24 [ 221.629066] [<c06ac07b>] ? lock_kernel+0x19/0x8c [ 221.629066] [<c01962e6>] ? sys_mount+0x51/0x9b [ 221.629066] [<c01962f9>] ? sys_mount+0x64/0x9b [ 221.629066] [<c01038bd>] ? sysenter_do_call+0x12/0x31 [ 221.629066] ======================= [ 221.629066] Code: 89 c2 c1 e2 08 c1 e8 08 09 c2 8b 85 e8 fd ff ff 66 89 50 06 89 c7 53 83 c7 08 56 57 68 c4 b3 80 c0 e8 8c 5c ef ff 89 d9 c1 e9 02 <f3> a5 89 d9 83 e1 03 74 02 f3 a4 83 c3 06 8b 95 e8 fd ff ff 0f [ 221.629066] EIP: [<c022d4b1>] hfsplus_find_cat+0x10d/0x151 SS:ESP 0068:c82d199c [ 221.629066] ---[ end trace e417a1d67f0d0066 ]--- Since hfsplus_cat_build_key_uni() returns void and only has one callsite, the check is performed at the callsite.

A very large directory with many read failures (either due to storage problems, or due to invalid size & blocks from corruption) will generate a printk storm as the filesystem continues to try to read all the blocks. This flood of messages can tie up the box until it is complete - which may be a very long time, especially for very large corrupted values. This is fixed by only reporting the corruption once each time we try to read the directory. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

We could run into ENOSPC error on ext2, even when there is free blocks on the filesystem. The problem is triggered in the case the goal block group has 0 free blocks , and the rest block groups are skipped due to the check of "free_blocks < windowsz/2". Current code could fall back to non reservation allocation to prevent early ENOSPC after examing all the block groups with reservation on , but this code was bypassed if the reservation window is turned off already, which is true in this case. This patch fixed two issues: 1) We don't need to turn off block reservation if the goal block group has 0 free blocks left and continue search for the rest of block groups. Current code the intention is to turn off the block reservation if the goal allocation group has a few (some) free blocks left (not enough for make the desired reservation window),to try to allocation in the goal block group, to get better locality. But if the goal blocks have 0 free blocks, it should leave the block reservation on, and continues search for the next block groups,rather than turn off block reservation completely. 2) we don't need to check the window size if the block reservation is off. The problem was originally found and fixed in ext4. Signed-off-by:

Currently, it is possible to set a graphics VESA mode at boot time via the vga= parameter even when no framebuffer driver supporting this is configured. This could lead to the system booting with a black screen, without a usable console. Fix this problem by only allowing to set graphics modes at boot time if a supporting framebuffer driver is configured. Signed-off-by:

Some BIOSes return error codes when queried for information about modes from their own modelist. uvesafb treats this as an error case and bails out. Change this behavior so that broken modes do not prevent the driver from working. Only the failure to retrieve information about any usable video mode is considered to be an error case.

The offset fixup code is now unnecessary as the fbcon core will call our set_par upon switch back from KD_GRAPHICS before anything else happens. I removed it as it would slow down accel operations. The fifo wait has been improved to avoid hitting the HW register as often, and the various accel ops are now performing better caching of register values. Overall, this improve accel performances. The imageblit acceleration does result in a small overall regression in performances on some machines (on the order of 5% on some x86), probably becaus the SW path provides a better bus utilisation, but I decided to ingnore that as the performances is still very good, and on the other hand, some machines such as some sparc64 get a 3 fold performance improvement.

Fix a couple of incomplete tests of the chip families in the engine init/reset code and proper initialization of the destination cache mode. The result should better match what the latest X radeon driver does. Signed-off-by:

Remove imacfb entirely, merging its DMI table into the (otherwise very similar) efifb driver. This also adds hardware support for many of the newer Intel Apple hardware. This has been fairly well tested; we've been shipping it in Fedora for some time. Signed-off-by:

A memory clock value (MCLK) is changed to a minimum required by a current mode bandwidth. This usually lowers the MCLK to its minimum (50 MHz) thus decreasing the card performance. Just leave the MCLK value set by card BIOS. The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a jitter on the screen. A countermeasure is to use the MCLK as pixclock source instead of a VCLK. The patch implements this as well. Signed-off-by:

The 16bpp mode did not work on the Cirrus cards as the visual type was set to DIRECTCOLOR instead of TRUECOLOR. The Alpine family used one incorrect register setting so this 16bpp modes generated wrong horizontal frequency. Signed-off-by:

Add support for Intel's 945GME graphics chip to the intelfb driver. I have assumed that the 945GME is identical to the already-supported 945GM apart from its PCI IDs; this is based on a quick look at the X driver for these chips which seems to treat them identically. The 945GME is used in the ASUS Eee 901, and I coded this in the hope that I'd be able to use it to get a console at the native 1024x600 resolution which is not known to the BIOS. I realised too late that the intelfb driver does not support mode changing on laptops, so it won't be any use for me. Signed-off-by:
