I was looking at how TOTAL_CAM_ENTRY is used and I saw this code. We print an error but continue writing "EntryNo" to a register as if it were valid. "EntryNo" is controlled by the user in rtl8192_ioctl() so it definitely can be invalid. I'm not positive what happens with the invalid data but it can't be good. Signed-off-by:

"EntryNo" is comes from the user in the ioctl and it's a number between 0-255. The ieee->swcamtable[] array only has 32 elements so it can result in memory corruption. Signed-off-by:

Previously we simplified the serverdown function to basically turn it into a dev_close(), but missed the analogous logic in visornic_resume() (which is essentially the "book-end" of visornic_serverdown_complete()). As a result, during IO partition recovery, the nic would go closed when the IO partition went away, but would never be opened again when the IO partition came back. This patch changes visornic_resume() to use dev_open(), so that it once again plays nicely with visornic_serverdown_complete(). Because dev_open() forces us into the visornic_open() path, other logic in visornic_resume() was no longer necessary, and lended to simplifying visornic_resume() even more. Fixes: 36645d72a377 ("staging: unisys: simplify visornic_serverdown_complete") Signed-off-by: -
Tim Sell authored
Because devdata->enab_dis_acked is the flag used to determine whether an enable/disable operation to the IO partition has completed, it should always be cleared prior to initiating the operation. The call added to visornic_enable_with_timeout() added in this patch makes the usage there consistent with visornic_disable_with_timeout(). Signed-off-by:

Tim Sell authored
In the patch which changed the serverdown logic to by synchronous, we were mistakenly holding on to devdata->priv_lock in the call to visornic_serverdown_complete(), which ultimately ended up recursively attempting to grab the same lock via the path: --> dev_close --> visornic_close() --> visornic_disable_with_timeout() Evidence: BUG: spinlock recursion on CPU#0, kworker/u2:0/1567 lock: 0xffff88002d7e4c90, .magic: dead4ead, .owner: kworker/ .owner_cpu: 0 CPU: 0 PID: 1567 Comm: kworker/u2:0 Tainted: G WC 4.2.0-rc3-ARCH+ #60 Hardware name: Dell Inc.

New writeback changes in 4.2-RC1 have exposed that we incorrectly set page_writeback on a page that is being written synchronously, which aside from this new crash (dereference of NULL inode->i_wb from set_page_writeback) likely threw off some related page statistics in the past.
