This reverts commit d52df4a35af569071fda3f4eb08e47cc7023f094.

This patch attempted to fix e100 for non-cache coherent memory
architectures by using the cb style code that eepro100 had and using
the EL and s bits from the RFD list. Unfortunately the hardware
doesn't work exactly like this and therefore this patch actually
breaks e100. Reverting the change brings it back to the previously
known good state for 2.6.22. The pending rewrite in progress to this
code can then be safely merged later.

hexdump: more output formatting

Add a prefix string parameter.  Callers are responsible for any string
length/alignment that they want to see in the output.  I.e., callers should
pad strings to achieve alignment if they want that.

Add rowsize parameter.  This is the number of raw data bytes to be printed
per line.  Must be 16 or 32.

Add a groupsize parameter.  This allows callers to dump values as 1-byte,
2-byte, 4-byte, or 8-byte numbers.  Default is 1-byte numbers.  If the
total length is not an even multiple of groupsize, 1-byte numbers are
printed.

Add an "ascii" output parameter.  This causes ASCII data output following
the hex data output.

Clean up some doc examples.

Align the ASCII output on all lines that are produced by one call.

Add a new interface, print_hex_dump_bytes(), that is a shortcut to
print_hex_dump(), using default parameter values to print 16 bytes in
byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.

fix sysrq-m oops

We aren't sampling for holes in memory.  Thus we encounter a section hole
with empty section map pointer for SPARSEMEM and OOPs for show_mem.  This
issue has been seen in 2.6.21, current git and current mm.  The patch below
is for mainline and mm.  It was boot tested for SPARSEMEM, current VMEMMAP
of Andy's in mm ml and DISCONTIGMEM.  A slightly different patch will be
posted to stable for 2.6.21.

Previous to commit f0a5a58aa812b31fd9f197c4ba48245942364eae memory_present
was called for node_start_pfn to node_end_pfn.  This would cover the
hole(s) with reserved pages and valid sections.  Most SPARSEMEM supported
arches do a pfn_valid check in show_mem before computing the page structure
address.

This issue was brought to my attention on IRC by Arnaldo Carvalho de Melo.

17 years agopi-futex: fix exit races and locking problems
Alexey Kuznetsov [Fri, 8 Jun 2007 20:47:00 +0000 (13:47 -0700)]
pi-futex: fix exit races and locking problems

1. New entries can be added to tsk->pi_state_list after task completed
   exit_pi_state_list(). The result is memory leakage and deadlocks.

2. handle_mm_fault() is called under spinlock. The result is obvious.

3. results in self-inflicted deadlock inside glibc.
   Sometimes futex_lock_pi returns -ESRCH, when it is not expected
   and glibc enters to for(;;) sleep() to simulate deadlock. This problem
   is quite obvious and I think the patch is right. Though it looks like
   each "if" in futex_lock_pi() got some stupid special case "else if". :-)

4. sometimes futex_lock_pi() returns -EDEADLK,
   when nobody has the lock. The reason is also obvious (see comment
   in the patch), but correct fix is far beyond my comprehension.
   I guess someone already saw this, the chunk:

                        if (rt_mutex_trylock(&q.pi_state->pi_mutex))
                                ret = 0;

   is obviously from the same opera. But it does not work, because the
   rtmutex is really taken at this point: wake_futex_pi() of previous
   owner reassigned it to us. My fix works. But it looks very stupid.
   I would think about removal of shift of ownership in wake_futex_pi()
   and making all the work in context of process taking lock.

From: Thomas Gleixner <tglx@linutronix.de>

Fix 1) Avoid the tasklist lock variant of the exit race fix by adding
    an additional state transition to the exit code.

    This fixes also the issue, when a task with recursive segfaults
    is not able to release the futexes.

Fix 2) Cleanup the lookup_pi_state() failure path and solve the -ESRCH
    problem finally.

Fix 3) Solve the fixup_pi_state_owner() problem which needs to do the fixup
    in the lock protected section by using the in_atomic userspace access
    functions.

    This removes also the ugly lock drop / unqueue inside of fixup_pi_state()

Fix 4) Fix a stale lock in the error path of futex_wake_pi()

Added some error checks for verification.

The -EDEADLK problem is solved by the rtmutex fixups.

17 years agosata_promise: use TF interface for polling NODATA commands

sata_promise: use TF interface for polling NODATA commands

sata_promise uses two different command modes - packet and TF.  Packet mode
is intelligent low-overhead mode while TF is the same old taskfile
interface.  As with other advanced interface (ahci/sil24),
ATA_TFLAG_POLLING has no effect in packet mode.  However, PIO commands are
issued using TF interface in polling mode, so pdc_interrupt() considers
interrupts spurious if ATA_TFLAG_POLLING is set.

This is broken for polling NODATA commands because command is issued using
packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING.
Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued
using TF interface if ATA_TFLAG_POLLING is set.

This patch fixes detection failure introduced by polling SETXFERMODE.

USB: cxacru: ignore error trying to start ADSL in atm_start

user) any error sending a START/STOP command to the device and there is at
least one firmware which never sends a response but appears to work
regardless.  Therefore atm_start should also continue if an error is received
so that such firmware is usable.

The official Conexant driver doesn't expect a reply either but this is for
another device (E2 router) and a commonly used firmware does respond.

Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing
ever checks for either of these values.

Reading the MAC address from atm_dev before atm_dev exists would have been

For completeness I've moved remove_device_file to atm_stop so it's not

xfrm: Add security check before flushing SAD/SPD

Currently we check for permission before deleting entries from SAD and
SPD, (see security_xfrm_policy_delete() security_xfrm_state_delete())
However we are not checking for authorization when flushing the SPD and
the SAD completely. It was perhaps missed in the original security hooks
patch.

This patch adds a security check when flushing entries from the SAD and
SPD.  It runs the entire database and checks each entry for a denial.
If the process attempting the flush is unable to remove all of the
entries a denial is logged the the flush function returns an error
without removing anything.

This is particularly useful when a process may need to create or delete
its own xfrm entries used for things like labeled networking but that
same process should not be able to delete other entries or flush the
entire database.

[AF_UNIX]: Fix stream recvmsg() race.

send()+close() on the peer, causing recv() to return zero, even though
the sent data should be received.

This happens if the send() and the close() is performed between
skb_dequeue() and checking sk->sk_shutdown in unix_stream_recvmsg():

process A  skb_dequeue() returns NULL, there's no data in the socket queue
process B  new data is inserted onto the queue by unix_stream_sendmsg()
process B  sk->sk_shutdown is set to SHUTDOWN_MASK by unix_release_sock()
process A  sk->sk_shutdown is checked, unix_release_sock() returns zero

I'm surprised nobody noticed this, it's not hard to trigger.  Maybe
it's just (un)luck with the timing.

It's possible to work around this bug in userspace, by retrying the
