* ide: HPA detect from resumeLee Trager2007-06-08
| | | | | | | | | | | | | | | | | | | Currently when system which have HPA require HPA to be detected and disabled upon resume from RAM or disk. The current IDE drivers do not do this nor does libata (obviously it since it doesn't support HPA yet). I have implemented this into the current IDE drivers and it has been tested by many others since 7/15/2006 in bug number 6840: http://bugzilla.kernel.org/show_bug.cgi?id=6840 and it has been confirmed to work fine with no problems. bart: added drv != NULL check to generic_ide_suspend() From: Lee Trager <lt73@cs.drexel.edu> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* it821x: RAID mode fixesBartlomiej Zolnierkiewicz2007-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DMA support for RAID mode broke after: commit 71ef51cc1756d1c56b57c70e7cc27a3559c81ee6 Author: Jens Axboe <axboe@suse.de> Date:   Fri Jul 28 09:02:17 2006 +0200     [PATCH] it821x: fix ide dma setup bug     Only enable dma for a valid speed setting.     Signed-off-by: Jens Axboe <axboe@suse.de> commit 0a8348d08677ad77ee353f96eb8745c693a05a13 Author: Jens Axboe <axboe@suse.de> Date:   Fri Jul 28 08:58:26 2006 +0200     [PATCH] ide: if the id fields looks screwy, disable DMA     It's the safer choice. Originally due to a bug in itx821x, but a     generally sound thing to do.     Signed-off-by: Jens Axboe <axboe@suse.de> However it worked by pure luck before Jens' fixes: bogus ide_dma_enable() usage in it821x driver combined with loosy check in ide_dma_verbose() allowed the hardware to operate in DMA mode. When these problems were fixed the DMA support broke... The source root for the regression turned out to be that the it821x.c code was clearing too much of id->field_valid. The IDE core code was using the original value of id->field_valid to do the tuning but later DMA got disabled in ide_dma_verbose() because of the incorrect id->field_valid fixup. Fix it. While at it: * Do fixup() after probing the drives but before tuning them (which is also OK w.r.t. ide_undecoded_slave() fixup). This change fixes device IDENTIFY data to be consistent before/after the tuning and allows us to remove extra re-tuning of drives from it821x_fixups(). * Fake MWDMA0 enabled/supported bits in IDENTIFY data if the device has DMA capable bit set (this is just to tell the IDE core that DMA is supported since it821x firmware takes care of DMA mode programming). * Don't touch timing registers and don't program transfer modes on devices et all when in RAID mode - depend solely on firmware to do the tuning (as suggested by Alan Cox and done in libata pata_it821x driver). Thanks for testing the patch goes out to Thomas Kuther.

* serverworks: fix CSB6 tuning logicBartlomiej Zolnierkiewicz2007-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | Problem noticed by Joe Zbiciak, see http://kerneltrap.org/node/8252 for details. On CSB6 the driver is using BIOS settings and not programming DMA/PIO timings itself. However the logic was completely broken and resulted in wrong timings being silently allowed (instead of being corrected by the driver). This bug would explain some data corruption/timeout issues with Serverworks MegaIDE in RAID mode that Alan Cox has fixed recently with: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2074a106f52b6371885afbd714e929d60d0e3f64 For 2.6.23 we may be better off with completely switching the driver to always programming timings (libata pata_serverworks.c driver is doing things this way and there were no problems reported so far) but for 2.6.22 lets fix the bug in the simplest and the least intrusive way.

| | | | | | | | | | | | | | | | | | | | | | The non-rt signal handling was never really used, so we don't break anything. This patch also cleans up the signal stack-frame to make it independent from the processor configuration. It also improves the method used for controlling single-stepping.

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.

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 recv() once in case of a zero return value.

Add a compat_release_match function that only drops the module reference on error and rename compat_check_calc_match to compat_find_calc_match to reflect the fact that it doesn't call the checkentry function.

Therefore the default config values they get are the ones at the time of these operations. Now that we're creating inet devices earlier, this changes the behaviour of default config values in an incompatible way (see bug #8519). This patch creates a compromise by setting the default values at the same point as before but only for those that have not been explicitly set by the user since the inet device's creation.

This creates a problem since we have moved the point where inetdev_init is called from when an address is added to where the device is registered. This patch is the first half of a set that tries to mimic the old behaviour while still calling inetdev_init. It propagates any changes to ipv4_devconf_dflt to those devices that have not had the corresponding attribute set. The next patch will forcibly set all values at the point where inetdev_init was previously called. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A time_wait socket inherits sk_bound_dev_if from the original socket, but it is not used when sending ACK packets using ip_send_reply. Fix by passing the oif to ip_send_reply in struct ip_reply_arg and use it for output routing. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

| * | | [BNX2]: Fix occasional counter corruption on 5708.Michael Chan2007-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The statistics block DMA on 5708 can be messed up occasionally on the average of about once per hour. If the user is reading the counters within one second after the corruption, the counters will be all messed up. One second later, the counters will be ok again until the next corruption occurs. The workaround is to disable the periodic statistics DMA. Instead, we manually trigger the DMA once a second in bnx2_timer(). This manual trigger of the DMA avoids the problem. As a consequence, we can only allow 0 or 1 second settings for ethtool -C statistics block. Thanks to Jean-Daniel Pauget <jd@disjunkt.com> and CaT <cat@zip.com.au> for reporting this rare problem.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug in the driver that only initializes half of the context memory on the 5708. Surprisingly, this works most of the time except for some occasional netdev watchdogs when sending a lot of 64-byte packets. The fix is to add the missing code to initialize the 2nd halves of all context memory. Signed-off-by: Michael Chan <mchan@broadcom.com> Acked-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.

* | | enable interrupts in user path of page fault.Steven Rostedt2007-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a minor fix, but what is currently there is essentially wrong. In do_page_fault, if the faulting address from user code happens to be in kernel address space (int *p = (int*)-1; p = 0xbed;) then the do_page_fault handler will jump over the local_irq_enable with the goto bad_area_nosemaphore; But the first line there sees this is user code and goes through the process of sending a signal to send SIGSEGV to the user task. This whole time interrupts are disabled and the task can not be preempted by a higher priority task. This patch always enables interrupts in the user path of the bad_area_nosemaphore.
