* [PATCH] autofs4: fix race in unhashed dentry codeJeff Mahoney2007-04-12
| | | | | | | | | | | | | | | | | | | | Commit f50b6f8691cae2e0064c499dd3ef3f31142987f0 introduced a race in autofs4 between autofs_lookup_unhashed() and autofs_dentry_release(). autofs_dentry_release() ends up clearing the ->dentry and ->inode members of autofs_info before removing it from the rehash list. The list is protected by the rehash lock in both functions, but since autofs_dentry_release() starts tearing the autofs_info struct down before removing it from the list, autofs_lookup_unhashed() can get a autofs_info with a NULL dentry. This patch moves the clearing of ->dentry and ->inode after the removal from the rehash list.

* [PATCH] reiserfs: fix key decrementingVladimir Saveliev2007-04-12
| | | | | | | | | | | | | | | | This patch fixes a bug in function decrementing a key of stat data item. Offset of reiserfs keys are compared as signed values. To set key offset to maximal possible value maximal signed value has to be used. This bug is responsible for severe reiserfs filesystem corruption which shows itself as warning vs-13060. reiserfsck fixes this corruption by filesystem tree rebuilding.

| | | | | | | | | | | If 'num_pages' were ever 1 more than a multiple of 8 (32bit platforms) or of 16 (64 bit platforms). filemap_attr would be allocated one 'unsigned long' shorter than required.

* [PATCH] cciss: unregister from SCSI before tearing down device resourcesBjorn Helgaas2007-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We must unregister from SCSI before we unmap device resources and unhook the IRQ handler.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is one significant difference between the behavior of root hubs (as embodied in host controller hardware) and external hubs: When a remote-wakeup signal is received, an external hub sends an interrupt message at the _end_ of the resume sequence but a root hub generates and interrupt at the _beginning_ of the resume sequence. The host system must poll for the end of the sequence. When ehci-hcd was converted to interrupt-driven operation instead of using polling, the remaining need for this particular poll was overlooked.

This is done using a workqueue (switched to from the iSER tasklet context). Meanwhile, the connection object (that holds the work struct) is released. If the workqueue function wasn't called yet, it will be called later with a NULL pointer, which will crash the kernel. The context switch (tasklet to workqueue) is not required, and everything can be done from the iSER tasklet. This eliminates the NULL work struct bug (and simplifies the code).

This is exactly how SFF8090i says it should respond. But ide-cd.c (in cdrom_decode_status() ) just sees sense key 5 and spews out an error. It then goes on to request sense data, and cdrom_log_sense() understands this error and doesn't log it. The patch, for kernel 2.6.20.4, suppresses this error message.

A simple way to exhibit this is to set the DMA timeout to 1 jiffy and run dd: The kernel will panic after a few minutes because ide_timer_expiry() tries to add a timer when it's already active. To fix this, we simply add a request generation count that gets incremented at every interrupt, and check in ide_timer_expiry() that we have not already handled a new interrupt before running the expiry function.

This causes the config to be freed before it is removed from the list, resulting in a crash when adding the next rule.

This defeats the whole point of setting slow_start_after_idle to zero. So test it there too. We do not cancel out the entire tcp_cwnd_validate() function so that if the sysctl is changed we still have the validation state maintained. Signed-off-by: David S. Miller <davem@davemloft.net>
