2005-08-29[NETLINK]: Add properly module refcounting for kernel netlink sockets.Harald Welte
- Remove bogus code for compiling netlink as module - Add module refcounting support for modules implementing a netlink protocol - Add support for autoloading modules that implement a netlink protocol as soon as someone opens a socket for that protocol Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NET]: Remove explicit initializations of skb->input_devDavid S. Miller
Instead, set it in one place, namely the beginning of netif_receive_skb(). Based upon suggestions from Jamal Hadi Salim. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NET]: Kill skb->real_devDavid S. Miller
Bonding just wants the device before the skb_bond() decapsulation occurs, so simply pass that original device into packet_type->func() as an argument. It remains to be seen whether we can use this same exact thing to get rid of skb->input_dev as well. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NET]: Remove HIPPI private from skbuff.hStephen Hemminger
This removes the private element from skbuff, that is only used by HIPPI. Instead it uses skb->cb[] to hold the additional data that is needed in the output path from hard_header to device driver. PS: The only qdisc that might potentially corrupt this cb[] is if netem was used over HIPPI. I will take care of that by fixing netem to use skb->stamp. I don't expect many users of netem over HIPPI Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NET]: Kill skb->listDavid S. Miller
Remove the "list" member of struct sk_buff, as it is entirely redundant. All SKB list removal callers know which list the SKB is on, so storing this in sk_buff does nothing other than taking up some space. Two tricky bits were SCTP, which I took care of, and two ATM drivers which Francois Romieu <romieu@fr.zoreil.com> fixed up. Signed-off-by: David S.

2005-08-27[PATCH] Remove race between con_open and con_closePaul Mackerras
[ 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.

2005-08-27[PATCH] sg.c: fix a memory leak in devices seq_file implementationJan Blunck
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>

2005-08-27[PATCH] Fix 6pack setting of MAC addressRalf Baechle
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.

2005-08-26[PATCH] IB/mthca: Handle context tables smaller than our chunk sizeRoland Dreier
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.

2005-08-26[PATCH] IB: userspace SRQ supportRoland Dreier
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.
