* [PATCH] move ->eh_strategy_handler to the transport classChristoph Hellwig2006-04-10
| | | | | | | | | | | | | Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.

* [PATCH] Fix buddy list race that could lead to page lru list corruptionsNick Piggin2006-04-10
| | | | | | | | | | | | | | | | | | | Rohit found an obscure bug causing buddy list corruption. page_is_buddy is using a non-atomic test (PagePrivate && page_count == 0) to determine whether or not a free page's buddy is itself free and in the buddy lists. Each of the conjuncts may be true at different times due to unrelated conditions, so the non-atomic page_is_buddy test may find each conjunct to be true even if they were not both true at the same time (ie. the page was not on the buddy lists).

* [Security] Keys: Fix oops when adding key to non-keyringDavid Howells2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | This fixes the problem of an oops occuring when a user attempts to add a key to a non-keyring key [CVE-2006-1522]. The problem is that __keyring_search_one() doesn't check that the keyring it's been given is actually a keyring. I've fixed this problem by: (1) declaring that caller of __keyring_search_one() must guarantee that the keyring is a keyring; and (2) making key_create_or_update() check that the keyring is a keyring, and return -ENOTDIR if it isn't. This can be tested by: keyctl add user b b `keyctl add user a a @s` Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [TG3]: Speed up SRAM access (2nd version)Michael Chan2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. David Miller informed me that an earlier version of the patch caused problems on sparc64 systems with built-in tg3 chips. This version fixes the problem by excluding all SUN built-in tg3 chips from doing MMIO SRAM access. TG3_FLAG_EEPROM_WRITE_PROT is also set unconditionally when TG3_FLG2_SUN_570X is set. This should be sane as all SUN chips are built-in and do not require Vaux switching. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Currently, this can be done from userspace with smcinit, a utility that comes with the irda-utils package. It messes with ioports and PCI settings, from userspace. Now with this patch, if we happen to be on one of the known to be faulty laptops, we preconfigure the chip from the driver.

| * [INET]: Move no-tunnel ICMP error to tunnel4/tunnel6Herbert Xu2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the sending of ICMP messages when there are no IPv4/IPv6 tunnels present to tunnel4/tunnel6 respectively. Please note that for now if xfrm4_tunnel/xfrm6_tunnel is loaded then no ICMP messages will ever be sent. This is similar to how we handle AH/ESP/IPCOMP. This move fixes the bug where we always send an ICMP message when there is no ip6_tunnel device present for a given packet even if it is later handled by IPsec. It also causes ICMP messages to be sent when no IPIP tunnel is present. I've decided to use the "port unreachable" ICMP message over the current value of "address unreachable" (and "protocol unreachable" by GRE) because it is not ambiguous unlike the other ones which can be triggered by other conditions. There seems to be no standard specifying what value must be used so this change should be OK. In fact we should change GRE to use this value as well. Incidentally, this patch also fixes a fairly serious bug in xfrm6_tunnel where we don't check whether the embedded IPv6 header is present before dereferencing it for the inside source address. This patch is inspired by a previous patch by Hugo Santos <hsantos@av.it.pt>. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

* Move request_standard_resources() back to before PCI probingLinus Torvalds2006-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This effectively undoes the PCI resource allocation changes done in commit b408cbc704352eccee301e1103b23203ba1c3a0e, but leaves the cleanups of that commit in place. We're going back to marking the resources reported by e820 busy _before_ doing PCI probing, so that any PCI resource that clashes with the BIOS- reported memory map will be reloacted to a non-clashing area. The reason? Larry Finger reports that his laptop has the cardbus controller set up by the BIOS so that it conflicts with the e820 memory map, and needs to be relocated. See http://bugzilla.kernel.org/show_bug.cgi?id=6337 for more details. We'll have to work out how to handle the fbcon problem that caused that commit in the first place in some other way.
