| * [PATCH] Fix 6pack setting of MAC addressRalf Baechle2005-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | [PATCH] Remove race between con_open and con_closePaul Mackerras2005-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ 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.

| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a severe problem with 2.6.13-rc7. Due to recent SCSI changes it is not possible to add any LUNs to the zfcp device driver anymore.

* | [PATCH] sg.c: fix a memory leak in devices seq_file implementationJan Blunck2005-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Jan Blunck <j.blunck@tu-harburg.de> Acked-by: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * | [TG3]: Fix ethtool loopback test lockupMichael Chan2005-08-25
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | The tg3_abort_hw() call in tg3_test_loopback() is causing lockups on some devices. tg3_abort_hw() disables the memory arbiter, causing tg3_reset_hw() to hang when it tries to write the pre-reset signature. tg3_abort_hw() should only be called after the pre-reset signature has been written. This is all done in tg3_reset_hw() so the tg3_abort_hw() call is unnecessary and can be removed.

Additionally, writing to temp1_reset and temp2_reset will not work as expected. The fix is straightforward.

* | Ignore disabled ROM resources at setupLinus Torvalds2005-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Writing even a disabled value seems to mess up some matrox graphics cards. It may be a card-related issue, but we may also be writing reserved low bits in the result. This was a fall-out of switching x86 over to the generic PCI resource allocation code, and needs more debugging. In particular, the old x86 code defaulted to not doing any resource allocations at all for ROM resources.
