* ieee1394_device_id has kernel_ulong_t field after an odd number of __u32 ones. Since mod_devicetable.h is included both from kernel and from host build helper, we may be in trouble if we are building on 32bit host for 64bit target - userland sees unsigned long long, kernel sees unsigned long and while their sizes match, alignments might not. Fixed by forcing alignment. Fortunately, almost nobody else needs that - the rest of such fields is naturally aligned as it is. * of_device_id has void * in it. Host userland helpers need kernel_ulong_t instead, since their void * might have nothing to do with the kernel one. Fixed in the same way it's done for similar problems in pcmcia_device_id (ifdef __KERNEL__). * pcmcia_device_id has the same problem as ieee1394_device_id. Fixed the same way.

It has been reported that the way Linux handles NODEFER for signals is not consistent with the way other Unix boxes handle it. I've written a program to test the behavior of how this flag affects signals and had several reports from people who ran this on various Unix boxes, confirming that Linux seems to be unique on the way this is handled. The way NODEFER affects signals on other Unix boxes is as follows: 1) If NODEFER is set, other signals in sa_mask are still blocked. 2) If NODEFER is set and the signal is in sa_mask, then the signal is still blocked. (Note: this is the behavior of all tested but Linux _and_ NetBSD 2.0 *). The way NODEFER affects signals on Linux: 1) If NODEFER is set, other signals are _not_ blocked regardless of sa_mask (Even NetBSD doesn't do this). 2) If NODEFER is set and the signal is in sa_mask, then the signal being handled is not blocked. The patch converts signal handling in all current Linux architectures to the way most Unix boxes work. Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU 3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX. * NetBSD was the only other Unix to behave like Linux on point #2. The main concern was brought up by point #1 which even NetBSD isn't like Linux. So with this patch, we leave NetBSD as the lonely one that behaves differently here with #2.

[ Same race and same patch also by Steven Rostedt <rostedt@goodmis.org> ] I have a laptop (G3 powerbook) which will pretty reliably hit a race between con_open and con_close late in the boot process and oops in vt_ioctl due to tty->driver_data being NULL. What happens is this: process A opens /dev/tty6; it comes into con_open() (drivers/char/vt.c) and assign a non-NULL value to tty->driver_data. Then process A closes that and concurrently process B opens /dev/tty6. Process A gets through con_close() and clears tty->driver_data, since tty->count == 1. However, before process A can decrement tty->count, we switch to process B (e.g. at the down(&tty_sem) call at drivers/char/tty_io.c line 1626). So process B gets to run and comes into con_open with tty->count == 2, as tty->count is incremented (in init_dev) before con_open is called. Because tty->count != 1, we don't set tty->driver_data. Then when the process tries to do anything with that fd, it oopses. The simple and effective fix for this is to test tty->driver_data rather than tty->count in con_open. The testing and setting of tty->driver_data is serialized with respect to the clearing of tty->driver_data in con_close by the console_sem. We can't get a situation where con_open sees tty->driver_data != NULL and then con_close on a different fd clears tty->driver_data, because tty->count is incremented before con_open is called. Thus this patch eliminates the race, and in fact with this patch my laptop doesn't oops.

I know that scsi procfs is legacy code but this is a fix for a memory leak. While reading through sg.c I realized that the implementation of /proc/scsi/sg/devices with seq_file is leaking memory due to freeing the pointer returned by the next() iterator method. Since next() might return NULL or an error this is wrong. This patch fixes it through using the seq_files private field for holding the reference to the iterator object. Here is a small bash script to trigger the leak. Use slabtop to watch the size-32 usage grow and grow. #!/bin/sh while true; do cat /proc/scsi/sg/devices > /dev/null done Signed-off-by: NJan Blunck <j.blunck@tu-harburg.de> Acked-by: NJames Bottomley <James.Bottomley@steeleye.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

- copy_from_user() can fail; ->write() must check its return value. - severe buffer overruns both in ->read() and ->write() - lseek to the end (i.e. to mmapper_size) and if (count + *ppos > mmapper_size) count = count + *ppos - mmapper_size; will do absolutely nothing. Then it will call copy_to_user(buf,&v_buf[*ppos],count); with obvious results (similar for ->write()). Fixed by turning read to simple_read_from_buffer() and by doing normal limiting of count in ->write(). - gratitious lock_kernel() in ->mmap() - it's useless there. - lots of gratuitous includes.

Don't check type of sax25_family; dev_set_mac_address has already done that before and anyway, the type to check against would have been ARPHRD_AX25. We only got away because AF_AX25 and ARPHRD_AX25 both happen to be defined to the same value. Don't check sax25_ndigis either; it's value is insignificant for the purpose of setting the MAC address and the check has shown to break some application software for no good reason.

When creating a table in context memory where the table is smaller than our chunk size, we don't want to allocate and map a full chunk. Instead, allocate just enough memory to cover the table. This can be pretty simple because all tables are a power-of-2 size, so either the table is a multiple of the chunk size, or it's smaller than one chunk.

Add SRQ support to userspace verbs module. This adds several commands and associated structures, but it's OK to do this without bumping the ABI version because the commands are added at the end of the list so they don't change the existing numbering. There are two cases to worry about: 1. New kernel, old userspace. This is OK because old userspace simply won't try to use the new SRQ commands. None of the old commands are changed. 2. Old kernel, new userspace. This works perfectly as long as userspace doesn't try to use SRQ commands. If userspace tries to use SRQ commands, it will get EINVAL, which is perfectly reasonable: the kernel doesn't support SRQs, so we couldn't do any better.
