12 years ago[PATCH] ext3: wrong error behavior
Vasily Averin [Wed, 27 Sep 2006 08:49:33 +0000]
[PATCH] ext3: wrong error behavior

SWsoft Virtuozzo/OpenVZ Linux kernel team has discovered that ext3 error
behavior was broken in linux kernels since 2.5.x versions by the following
patch:

2002/10/31 02:15:26-05:00 tytso@snap.thunk.org
Default mount options from superblock for ext2/3 filesystems
http://linux.bkbits.net:8080/linux-2.6/gnupatch@3dc0d88eKbV9ivV4ptRNM8fBuA3JBQ

In case ext3 file system is mounted with errors=continue
(EXT3_ERRORS_CONTINUE) errors should be ignored when possible.  However at
present in case of any error kernel aborts journal and remounts filesystem
to read-only.  Such behavior was hit number of times and noted to differ
from that of 2.4.x kernels.

This patch fixes this:
- do nothing in case of EXT3_ERRORS_CONTINUE,
- set EXT3_MOUNT_ABORT and call journal_abort() in all other cases
- panic() should be called after ext3_commit_super() to save
 sb marked as EXT3_ERROR_FS

[PATCH] JBD: 16T fixes

These are a few places I've found in jbd that look like they may not be
16T-safe, or consistent with the use of unsigned longs for block
containers.  Problems here would be somewhat hard to hit, would require
journal blocks past the 8T boundary, which would not be terribly common.
Still, should fix.

(some of these have come from the ext4 work on jbd as well).

I think there's one more possibility that the wrap() function may not be
safe IF your last block in the journal butts right up against the 232 block
boundary, but that seems like a VERY remote possibility, and I'm not
worrying about it at this point.

12 years ago[PATCH] fix ext3 mounts at 16T
Eric Sandeen [Wed, 27 Sep 2006 08:49:29 +0000]
[PATCH] fix ext3 mounts at 16T

I need to do some actual IO testing now, but this gets things mounting for
a 16T ext3 filesystem.  (patched up e2fsprogs is needed too, I'll send that
off the kernel list)

This patch fixes these issues in the kernel:

o sbi->s_groups_count overflows in ext3_fill_super()

sbi->s_groups_count = (le32_to_cpu(es->s_blocks_count) -
       le32_to_cpu(es->s_first_data_block) +
       EXT3_BLOCKS_PER_GROUP(sb) - 1) /
      EXT3_BLOCKS_PER_GROUP(sb);

  at 16T, s_blocks_count is already maxed out; adding
  EXT3_BLOCKS_PER_GROUP(sb) overflows it and groups_count comes out to 0.
  Not really what we want, and causes a failed mount.

  Feel free to check my math (actually, please do!), but changing it this
  way should work & avoid the overflow:

  (A + B - 1)/B changed to: ((A - 1)/B) + 1

o ext3_check_descriptors() overflows range checks

  ext3_check_descriptors() iterates over all block groups making sure
  that various bits are within the right block ranges...  on the last pass
  through, it is checking the error case

   [item] >= block + EXT3_BLOCKS_PER_GROUP(sb)

  where "block" is the first block in the last block group.  The last
  block in this group (and the last one that will fit in 32 bits) is block
  + EXT3_BLOCKS_PER_GROUP(sb)- 1.  block + EXT3_BLOCKS_PER_GROUP(sb) wraps
  back around to 0.

  so, make things clearer with "first_block" and "last_block" where those
  are first and last, inclusive, and use <, > rather than <, >=.

  Finally, the last block group may be smaller than the rest, so account
  for this on the last pass through: last_block = sb->s_blocks_count - 1;

(a similar patch could be done for ext2; does anyone in their right mind
use ext2 at 16T?  I'll send an ext2 patch doing the same thing if that's
warranted)

[MIPS] fstatat syscall names

MIPS is the only port to call its fstatat()-related syscalls
"__NR_fstatat".  Now I can see why that might be seen as every
other port being wrong, but I think for o32, it is at best confusing.
__NR_fstat provides a plain (32-bit) stat while __NR_fstatat provides a
64-bit stat.  Changing the name to __NR_fstatat64 would make things more
explicit, match x86, and make the glibc port slightly easier.

The current name is more appropriate for n32 and n64, but it would be
appropriate for other 64-bit targets too, and those targets have chosen
to call it __NR_newfstatat instead.  Using the same name for MIPS would
again be more consistent and make the glibc port slightly easier.

I'm not wedded to this idea if the current names are preferred,
but FWIW...

[MIPS] The o32 fstatat syscall behaves differently on 32 and 64 bit kernels

While working on a glibc patch to support the fstatat() functions[1],
I noticed that the o32 implementation behaves differently on 32-bit and
64-bit kernels; the former provides a stat64 while the latter provides
a plain (o32) stat.  I think the former is what's intended, as there is
no separate fstatat64.  It's also what x86 does.

I think this is just a case of a compat too far.

[1] I've seen Khem's patch, but I don't think it's right.

Kevin D. Kissell [Tue, 12 Sep 2006 10:08:08 +0000]
[MIPS] Patch to arch/mips/mips-boards/generic/time.c

In hooking up the perf counter overflow interrupt to the experimental
deprecated-real-soon-now /proc/perf interface last night, I had to
revisit arch/mips/mips-boards/generic/time.c, and discovered that
when the 2.6.9-based SMTC prototype was merged with the more
recent tree, it was missed that arch/mips/kernel/time.c had changed
so that even in SMP kernels, timer_interrupt() calls
local_timer_interrupt(), so there is no longer a need to invoke it
directly from mips_timer_interrupt() in those cases where
timer_interrupt() has been called.  So I got rid of that, and added the
invocation of perf_irq() if Cause.PCI is set, more-or-less following the
same logic as in the non-SMTC case, with the modifications that (a) a
runtime check for Release 2 isn't done, because it's redundant in SMTC),
and (b) we check for a clock interrupt regardless of the value returned
by the perf counter service - I don't understand why we'd want to control
that with perf_irq(), but maybe one of you knows the story.  I also got
rid of the stupid warning about the unused variable when compiled for
SMTC (another artifact of the merge). The result hasn't been beaten to
death, but boots, seems stable, and supports extended precision event
counting.

Alexander Bigga [Tue, 29 Aug 2006 14:48:34 +0000]
[MIPS] Fix for pci config_access on alchemy au1x000

I've encountered a serious problem with PCI config space access on Au1x000
platforms with recent 2.6.x-kernel. With 2.4.31 the same hardware works fine.
So I was looking for the differences:

Symptoms:
- no PCI-device is seen on bootup though two or three cards are present
- lspci output is empty
- OR: lspci shows 20 times the same device
(- OR: in some slot-configurations it worked anyhow)

System(s):
1. platform with Au1500 and three PCI-devices (actually a mycable XXS1500
    with backplane for three PCI-devices)
2. platform with Au1550 and two PCI-devices (custom board)

Debugging:
I digged down to the config_access() of the au1xxx-processors in
arch/mips/pci/ops-au1000.c and switched on DEBUG.

The code of config_access() seems to be almost the same as of the
2.4.x-kernel. But the "pci_cfg_vm->addr" returned by get_vm_area(0x2000, 0)
once on booting is different. That's of course not forbidden. But the
alignment seems to be wrong. In my case, I received:

2.4.31: pci_cfg_vm->addr = c0000000
2.6.18-rc5: pci_cfg_vm->addr = c0101000

To make it short: With 2.6.x it fails on the first config-access with:
"PCI ERR detected: status 83a00356".

Fixup:
My fix is now, to use the VM_IOREMAP-flag in the get_vm_area call. This flag
seems to be introduced in mm/vmalloc.c a long time ago (in 2.6.7-bk13, I
found in gitweb).
Now, the returned address is pci_cfg_vm->addr = c0104000 and everything works
fine.
