17 years agoFix simplex adapters with libata
Petr Vandrovec [Thu, 8 Mar 2007 09:12:12 +0000 (10:12 +0100)]
Fix simplex adapters with libata

Recently I got my hands on nVidia's MCP61 PM-AM board, and
it contains IDE chip configured by BIOS with only primary
channel enabled.  This confuses code which probes for
device DMA capabilities - it gets 0x60 (happy duplex
device) from primary channel BMDMA, but 0xFF (nobody here)
from secondary channel BMDMA.  Due to this code then believes
that chip is simplex.  I do not address this problem in
my patch, as I'm not sure how to handle this.  Probably
ata_pci_init_one should have bitmap of enabled/possible
interfaces instead of their count, but it looks like
quite intrusive change, and maybe we do not care - for device
with only one channel simplex and regular DMA engines are
same.

But making device simplex pointed out that support for
DMA on simplex devices is currently broken - ata_dev_xfermask
tests whether device is simplex and if it is whether DMA
engine was assigned to this port.  If not then it strips
out DMA bits from device.  Problem is that code which assigns
DMA engine to port in ata_set_mode first detect device
mode and assigns DMA engine to channel only if some DMA
capable device was found.

And as xfermask stripped out DMA bits, host->simplex_claimed
is always NULL with current implementation.

By allowing DMA either if simplex_claimed is NULL or if it
points to current port DMA can be finally used - it gets
assigned to first port which contains any DMA capable
device.

[PATCH] x86_64: fix 2.6.18 regression - PTRACE_OLDSETOPTIONS should be accepted

Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c

since it is wise enough to use PTRACE_OLDSETOPTIONS to be binary compatible
with 2.4 host kernels.

Until 2.6.17 (commit f0f2d6536e3515b5b1b7ae97dc8f176860c8c2ce) we had:

       default:
                return sys_ptrace(request, pid, addr, data);

Instead here we have:
        case PTRACE_GET_THREAD_AREA:
case ...:
                return sys_ptrace(request, pid, addr, data);

        default:
                return -EINVAL;

This change was a style change - when a case is added, it must be
explicitly tested this way.  In this case, not enough testing was done.

The security hooks to check permissions to remove an xfrm_policy were
actually done after the policy was removed.  Since the unlinking and
deletion are done in xfrm_policy_by* functions this moves the hooks
inside those 2 functions.  There we have all the information needed to
do the security check and it can be done before the deletion.  Since
auditing requires the result of that security check err has to be passed
back and forth from the xfrm_policy_by* functions.

This patch also fixes a bug where a deletion that failed the security
check could cause improper accounting on the xfrm_policy
(xfrm_get_policy didn't have a put on the exit path for the hold taken
by xfrm_policy_by*)

It also fixes the return code when no policy is found in
xfrm_add_pol_expire.  In old code (at least back in the 2.6.18 days) err
wasn't used before the return when no policy is found and so the
initialization would cause err to be ENOENT.  But since err has since
been used above when we don't get a policy back from the xfrm_policy_by*

17 years ago[DCCP]: Revert patch which disables bidirectional mode
Gerrit Renker [Wed, 7 Mar 2007 20:53:48 +0000 (12:53 -0800)]
[DCCP]: Revert patch which disables bidirectional mode

This reverts an earlier patch which disabled bidirectional mode, meaning that
a listening (passive) socket was not allowed to write to the other (active)
end of the connection.

This mode had been disabled when there were problems with CCID3, but it
imposes a constraint on socket programming and thus hinders deployment.

A change is included to ignore RX feedback received by the TX CCID3 module.

Many thanks to Andre Noll for pointing out this issue.

[GFS2] fix hangup when multiple processes are trying to write to the same file

This fixes a problem I encountered while running bonnie++.  When you have one
thread that opens a file and starts to write to it, and then another thread that
tries to open and write to the same file, the second thread will loop forever
trying to grab the inode lock for that inode.  Basically we come in through
generic_buffered_file_write, which calls gfs2_prepare_write, which then attempts
to grab the glock.  Because we don't own the lock, gfs2_prepare_write gets
GLR_TRYFAILED, which returns AOP_TRUNCATED_PAGE to generic_buffered_file_write.
At this point generic_buffered_file_write loops around again and immediately
retries the prepare_write.  This means that the second process never gets off of
the processor in order to allow the process that holds the lock to finish its
work and let go of the lock.  This patch makes gfs2_glock_nq schedule() if it
gets back a GLR_TRYFAILED, which resolves this problem.
