2006-02-14[PATCH] tty reference count fixPaul Fulghum
Fix hole where tty structure can be released when reference count is non zero. Existing code can sleep without tty_sem protection between deciding to release the tty structure (setting local variables tty_closing and otty_closing) and setting TTY_CLOSING to prevent further opens. An open can occur during this interval causing release_dev() to free the tty structure while it is still referenced. This should fix bugzilla.kernel.org [Bug 6041] New: Unable to handle kernel paging request In Bug 6041, tty_open() oopes on accessing the tty structure it has successfully claimed. Bug was on SMP machine with the same tty being opened and closed by multiple processes, and DEBUG_PAGEALLOC enabled.

2006-02-11[PATCH] tipar fixesAndrew Morton
- tipar_open(): fix unsigned comparison - tipar_open(): don't permit NULL pardevice (probably unneeded given the above fix). - tipar_init_module(): handle the situation where parport_register_driver() failed to register any devices (parport_register_driver() drops the ->attach return value on the floor). This probably makes fixes #1 and #2 unneeded. - tipar_init_module(): fix various error-path resource leaks.

2006-02-03[PATCH] IPMI: fix issues reported by Coverity in ipmi_msghandler.cJayachandran C
While looking to the report by Coverity in ipmi, I came across the following issue: The IPMI message handler relies on two defines which are the same -one in include/linux/ipmi.h #define IPMI_NUM_CHANNELS 0x10 and one in drivers/char/ipmi/ipmi_msghandler. #define IPMI_MAX_CHANNELS 16 These are used interchangeably in ipmi_msghandler.c, but since the array addr->channels[] is of size IPMI_MAX_CHANNELS, I have made a patch that uses IPMI_MAX_CHANNELS for all the checks for the array index. NOTE: You could probably remove the line that defines IPMI_NUM_CHANNELS from ipmi.h, or move IPMI_MAX_CHANNELS to ipmi.h Signed-off-by: Jayachandran C. <c.jayachandran@gmail.com> Cc: Corey Minyard <minyard@acm.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-02-03[PATCH] new tty buffering locking fixPaul Fulghum
Change locking in the new tty buffering facility from using tty->read_lock, which is currently ignored by drivers and thus ineffective. New locking uses a new tty buffering specific lock enforced centrally in the tty buffering code. Two drivers (esp and cyclades) are updated to use the tty buffering functions instead of accessing tty buffering internals directly. This is required for the new locking to work.

At the 2.6.12 timeframe ipmi_si_intf.c was patched to provide default register spacings in try_init_acpi() if the register spacing was set to zero, similar to code in other routines. Unfortunately, another patch was simultaneously added that exits early from try_init_acpi() if the register spacings are set to zero, circumventing the new defaults. This patch removes the early exit code and some incorrect comments that aren't present in other common code snippets.
