* [AX25] ax25_timer: use mod_timer instead of add_timerJarek Poplawski2008-02-133-44/+23Star
| | | | | | | | | | | | | According to one of Jann's OOPS reports it looks like BUG_ON(timer_pending(timer)) triggers during add_timer() in ax25_start_t1timer(). This patch changes current use of: init_timer(), add_timer() and del_timer() to setup_timer() with mod_timer(), which should be safer anyway.

This lockdep report shows that ax25_route_lock is taken for reading in softirq context, and for writing in process context with BHs enabled.

* [AX25] af_ax25: remove sock lock in ax25_info_show()Jarek Poplawski2008-02-131-4/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This lockdep warning: > ======================================================= > [ INFO: possible circular locking dependency detected ] > 2.6.24 #3 > ------------------------------------------------------- > swapper/0 is trying to acquire lock: > (ax25_list_lock){-+..}, at: [<f91dd3b1>] ax25_destroy_socket+0x171/0x1f0 [ax25] > > but task is already holding lock: > (slock-AF_AX25){-+..}, at: [<f91dbabc>] ax25_std_heartbeat_expiry+0x1c/0xe0 [ax25] > > which lock already depends on the new lock. ... shows that ax25_list_lock and slock-AF_AX25 are taken in different order: ax25_info_show() takes slock (bh_lock_sock(ax25->sk)) while ax25_list_lock is held, so reversely to other functions. To fix this the sock lock should be moved to ax25_info_start(), and there would be still problem with breaking ax25_list_lock (it seems this "proper" order isn't optimal yet). But, since it's only for reading proc info it seems this is not necessary (e.g. ax25_send_to_raw() does similar reading without this lock too). So, this patch removes sock lock to avoid deadlock possibility; there is also used sock_i_ino() function, which reads sk_socket under proper read lock. Additionally printf format of this i_ino is changed to %lu. Reported-by: Bernard Pidoux F6BVP <f6bvp@free.fr> Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S.

* [IPV4]: Remove IP_TOS setting privilege checks.David S. Miller2008-02-131-5/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various RFCs have all sorts of things to say about the CS field of the DSCP value. In particular they try to make the distinction between values that should be used by "user applications" and things like routing daemons. This seems to have influenced the CAP_NET_ADMIN check which exists for IP_TOS socket option settings, but in fact it has an off-by-one error so it wasn't allowing CS5 which is meant for "user applications" as well. Further adding to the inconsistency and brokenness here, IPV6 does not validate the DSCP values specified for the IPV6_TCLASS socket option. The real actual uses of these TOS values are system specific in the final analysis, and these RFC recommendations are just that, "a recommendation". In fact the standards very purposefully use "SHOULD" and "SHOULD NOT" when describing how these values can be used. In the final analysis the only clean way to provide consistency here is to remove the CAP_NET_ADMIN check. The alternatives just don't work out: 1) If we add the CAP_NET_ADMIN check to ipv6, this can break existing setups. 2) If we just fix the off-by-one error in the class comparison in IPV4, certain DSCP values can be used in IPV6 but not IPV4 by default. So people will just ask for a sysctl asking to override that. I checked several other freely available kernel trees and they do not make any privilege checks in this area like we do. For the BSD stacks, this goes back all the way to Stevens Volume 2 and beyond. Signed-off-by: David S. Miller <davem@davemloft.net>

This breaks on 32 bits platforms that support 64 bits MMIO resources such as ppc 44x. This fixes it by removing those temporary variables and passing directly the result of pci_resource_start/len to ioremap. The side effect is that I removed the assignments to the netdev fields mem_start, mem_end and base_addr, which are totally useless for PCI devices.

V2 - Fix the bug that bringing down and up the interface keeps rx disabled. - Make 'gelic_net_poll_controller()' extern , as David Woodhouse pointed out at the previous submission. - Fix weird usage of member names for the rx descriptor chain V1 - Export functions which are convenient for both interfaces - Move irq allocation/release code to driver probe/remove handlers because interfaces share interrupts. - Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb() as the interfaces share the hardware rx queue. - Add gelic_port struct in order to abstract dual interface handling - Change handlers for hardware queues so that they can handle dual {source,destination} interfaces. - Use new NAPI functions This is a prerequisite for the new PS3 wireless support.
