2010-03-15i4l: silence compiler warnings for array access in Eicon DIVA ISDN driverIan Munsie
When compiling this driver, the compiler throws the following warnings: drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds This arises from the particular semantics the driver is using to write to the nlc array (static byte[256]). The array has a length in byte 0 followed by a T30_INFO struct starting at byte 1. The T30_INFO struct has a number of variable length strings after the station_id entry, which cannot be explicitly defined in the struct and the driver accesses them with an array index to station_id beyond the length of station_id. This patch merely changes the semantics that the driver uses to access the entries after the station_id entry to use the original 256 byte nlc array taking the offset and length of the station_id entry to calculate where to write in the array, thereby silencing the warning.

2009-11-28pcmcia: rework the irq_req_t typedefDominik Brodowski
Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

2009-03-30proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
