11 years agox86: Fix 32-bit MSI-X allocation leakage
PJ Waskiewicz [Sat, 26 Apr 2008 00:58:52 +0000]
x86: Fix 32-bit MSI-X allocation leakage

This bug was introduced in the 2.6.24 i386/x86_64 tree merge, where
MSI-X vector allocation will eventually fail.  The cause is the new
bit array tracking used vectors is not getting cleared properly on
IRQ destruction on the 32-bit APIC code.

This can be seen easily using the ixgbe 10 GbE driver on multi-core
systems by simply loading and unloading the driver a few times.
Depending on the number of available vectors on the host system, the
MSI-X allocation will eventually fail, and the driver will only be
able to use legacy interrupts.

I am generating the same patch for both stable trees for 2.6.24 and
2.6.25.

[MIPS] Pb1200/DBAu1200: move platform code to its proper place

Since both the IDE interface and SMC 91C111 Ethernet chip are on-board
devices, not SOC devices, move the platform device registration form the
common to the board specific code.

While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:

- change 'au1200_ide0_' variable name prefix to the mere 'ide_';

- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
  name of the chip used on the boards;

- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
  on-board devices;

- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
  the macros describing the Ethernet chip for consistency with the IDE
  macros;

- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is
  indeed a shift count) in the names of the macros describing the IDE
  interface.

Fold the SB-1 specific implementation of clear_page/copy_page in the

  - It allows adjustment of loop unfolling, which helps to reduce the

    will overflow the addiu immediate).

I saw this problem recently.  With this kernel-doc:

 * Note: some important info
 *
 * Note: other important info

kernel-doc uses the "section name" (preceding the ':', like "Note") as a hash
key for storing the descriptive text ("blah important info").  It is (was)
possible to have duplicate (colliding) section names, without any kind of
warning or error.

kernel-doc happily used the latter descriptive text for all instances of
printing the <section-name> descriptive text and the former important info
was lost.

One way to "fix" this is to modify the kernel-doc comments, e.g.:

 * Note1: foo bar
 *
 * Note.2: blah zay

For now, kernel-doc will signal an error when it sees colliding section names
like this.

11 years agofat: detect media without partition table correctly
Frank Seidel [Mon, 28 Apr 2008 09:16:31 +0000]
fat: detect media without partition table correctly

I received a complaint that some FAT formated medias (e.g.  sd memory cards)
trigger a "unknown partition table" message even though there is no partition
table and they work correctly, while in general (when e.g.  formated with
mkdosfs or even Windows Vista) this message is not shown.

Currently this seems only to happen when the medias get formatted with Windows
XP (and possibly Win 2000).  Then the boot indicator byte contains garbage
(part of text message) and so do the other parts checked by msdos_paritition
which then later triggers this message.

References: novell bug #364365

Most fat formatted media without partition table contains zeros in the boot
indication and the other tested bytes and so falls through the checks in
msdos_partition, leading it to return with 1 (all is fine).

But some (e.g.  WinXP formatted) fat fomated medias don't use boot_ind and so
the check fails and causes a "unkown partition table" warning eventhough there
is none and everything would be fine.

This additional check directly verifies if there is a fat formatted medium
without a partition table.

fat: Add allow_utime option

Normally utime(2) checks current process is owner of the file, or it
has CAP_FOWNER capability.  But FAT filesystem doesn't have uid/gid as
on disk info, so normal check is too unflexible.

With this option you can relax it.

11 years agoreiserfs: unpack tails on quota files
Jan Kara [Mon, 28 Apr 2008 09:16:23 +0000]
reiserfs: unpack tails on quota files

Quota files cannot have tails because quota_write and quota_read functions do
not support them.  So far when quota files did have tail, we just refused to
turn quotas on it.  Sadly this check has been wrong and so there are now
plenty installations where quota files don't have NOTAIL flag set and so now
after fixing the check, they suddently fail to turn quotas on.  Since it's
easy to unpack the tail from kernel, do this from reiserfs_quota_on() which
solves the problem and is generally nicer to users anyway.

11 years agojbd: fix possible journal overflow issues
Josef Bacik [Mon, 28 Apr 2008 09:16:12 +0000]
jbd: fix possible journal overflow issues

There are several cases where the running transaction can get buffers added to
its BJ_Metadata list which it never dirtied, which makes its t_nr_buffers
counter end up larger than its t_outstanding_credits counter.

This will cause issues when starting new transactions as while we are logging
buffers we decrement t_outstanding_buffers, so when t_outstanding_buffers goes
negative, we will report that we need less space in the journal than we
actually need, so transactions will be started even though there may not be
enough room for them.  In the worst case scenario (which admittedly is almost
impossible to reproduce) this will result in the journal running out of space.

The fix is to only
refile buffers from the committing transaction to the running transactions
BJ_Modified list when b_modified is set on that journal, which is the only way
to be sure if the running transaction has modified that buffer.

This patch also fixes an accounting error in journal_forget, it is possible
that we can call journal_forget on a buffer without having modified it, only
gotten write access to it, so instead of freeing a credit, we only do so if
the buffer was modified.  The assert will help catch if this problem occurs.
Without these two patches I could hit this assert within minutes of running
postmark, with them this issue no longer arises.  Thank you,

Josef Bacik [Mon, 28 Apr 2008 09:16:10 +0000]
jbd: fix the way the b_modified flag is cleared

Currently at the start of a journal commit we loop through all of the buffers
on the committing transaction and clear the b_modified flag (the flag that is
set when a transaction modifies the buffer) under the j_list_lock.

The problem is that everywhere else this flag is modified only under the jbd
lock buffer flag, so it will race with a running transaction who could
potentially set it, and have it unset by the committing transaction.

This is also a big waste, you can have several thousands of buffers that you
are clearing the modified flag on when you may not need to.  This patch
removes this code and instead clears the b_modified flag upon entering
do_get_write_access/journal_get_create_access, so if that transaction does
indeed use the buffer then it will be accounted for properly, and if it does
not then we know we didn't use it.

That will be important for the next patch in this series.  Tested thoroughly
by myself using postmark/iozone/bonnie++.
