2007-11-29[SUNGEM]: Fix NAPI regression with reset workJohannes Berg
sungem's gem_reset_task() will unconditionally try to disable NAPI even when it's called while the interface is not operating and hence the NAPI struct isn't enabled. Make napi_disable() depend on gp->running. Also removes a superfluous test of gp->running in the same function.

2007-11-27[XFRM]: Fix leak of expired xfrm_statesPatrick McHardy
The xfrm_timer calls __xfrm_state_delete, which drops the final reference manually without triggering destruction of the state. Change it to use xfrm_state_put to add the state to the gc list when we're dropping the last reference. The timer function may still continue to use the state safely since the final destruction does a del_timer_sync().

2007-11-26[SKBUFF]: Free old skb properly in skb_morphHerbert Xu
The skb_morph function only freed the data part of the dst skb, but leaked the auxiliary data such as the netfilter fields. This patch fixes this by moving the relevant parts from __kfree_skb to skb_release_all and calling it in skb_morph. It also makes kfree_skbmem static since it's no longer called anywhere else and it now no longer does skb_release_data. Thanks to Yasuyuki KOZAKAI for finding this problem and posting a patch for it.

2007-11-26[IPV4]: Fix memory leak in inet_hashtables.h when NUMA is onPavel Emelyanov
The inet_ehash_locks_alloc() looks like this: #ifdef CONFIG_NUMA if (size > PAGE_SIZE) x = vmalloc(...); else #endif x = kmalloc(...); Unlike it, the inet_ehash_locks_alloc() looks like this: #ifdef CONFIG_NUMA if (size > PAGE_SIZE) vfree(x); else #else kfree(x); #endif The error is obvious - if the NUMA is on and the size is less than the PAGE_SIZE we leak the pointer (kfree is inside the #else branch). Compiler doesn't warn us because after the kfree(x) there's a "x = NULL" assignment, so here's another (minor?) bug: we don't set x to NULL under certain circumstances. Boring explanation, I know...

2007-11-26[IPSEC]: Temporarily remove locks around copying of non-atomic fieldsHerbert Xu
The change 050f009e16f908932070313c1745d09dc69fd62b [IPSEC]: Lock state when copying non-atomic fields to user-space caused a regression. Ingo Molnar reports that it causes a potential dead-lock found by the lock validator as it tries to take x->lock within xfrm_state_lock while numerous other sites take the locks in opposite order. For 2.6.24, the best fix is to simply remove the added locks as that puts us back in the same state as we've been in for years. For later kernels a proper fix would be to reverse the locking order for every xfrm state user such that if x->lock is taken together with xfrm_state_lock then it is to be taken within it.

2007-11-23[TCP] MTUprobe: Cleanup send queue check (no need to loop)Ilpo Järvinen
The original code has striking complexity to perform a query which can be reduced to a very simple compare. FIN seqno may be included to write_seq but it should not make any significant difference here compared to skb->len which was used previously. One won't end up there with SYN still queued. Use of write_seq check guarantees that there's a valid skb in send_head so I removed the extra check.

2007-11-23[TCP]: MTUprobe: receiver window & data available checks fixedIlpo Järvinen
It seems that the checked range for receiver window check should begin from the first rather than from the last skb that is going to be included to the probe. And that can be achieved without reference to skbs at all, snd_nxt and write_seq provides the correct seqno already. Plus, it SHOULD account packets that are necessary to trigger fast retransmit [RFC4821]. Location of snd_wnd < probe_size/size_needed check is bogus because it will cause the other if() match as well (due to snd_nxt >= snd_una invariant). Removed dead obvious comment.

This is silly, but I have turned the CONFIG_IP_VS to m, to check the compilation of one (recently sent) fix and set all the CONFIG_IP_VS_PROTO_XXX options to n to speed up the compilation. In this configuration the compiler warns me about CC [M] net/ipv4/ipvs/ip_vs_proto.o net/ipv4/ipvs/ip_vs_proto.c:49: warning: 'register_ip_vs_protocol' defined but not used Indeed. With no protocols selected there are no calls to this function - all are compiled out with ifdefs. Maybe the best fix would be to surround this call with ifdef-s or tune the Kconfig dependences, but I think that marking this register function as __used is enough. No?

2007-11-20[NETFILTER]: Fix kernel panic with REDIRECT target.Evgeniy Polyakov
When connection tracking entry (nf_conn) is about to copy itself it can have some of its extension users (like nat) as being already freed and thus not required to be copied. Actually looking at this function I suspect it was copied from nf_nat_setup_info() and thus bug was introduced. Report and testing from David <david@unsolicited.net>. [ Patrick McHardy states: I now understand whats happening: - new connection is allocated without helper - connection is REDIRECTed to localhost - nf_nat_setup_info adds NAT extension, but doesn't initialize it yet - nf_conntrack_alter_reply performs a helper lookup based on the new tuple, finds the SIP helper and allocates a helper extension, causing reallocation because of too little space - nf_nat_move_storage is called with the uninitialized nat extension So your fix is entirely correct, thanks a lot :) ] Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2007-11-20[WIRELESS] WEXT: Fix userspace corruption on 64-bit.David S. Miller
On 64-bit systems sizeof(struct ifreq) is 8 bytes larger than sizeof(struct iwreq). For GET calls, the wireless extension code copies back into userspace using sizeof(struct ifreq) but userspace and elsewhere only allocates a "struct iwreq". Thus, this copy writes past the end of the iwreq object and corrupts whatever sits after it in memory. Fix the copy_to_user() length. This particularly hurts the compat case because the wireless compat code uses compat_alloc_userspace() and right after this allocated buffer is the current bottom of the user stack, and that's what gets overwritten by the copy_to_user() call.

2007-11-19[TCP]: Problem bug with sysctl_tcp_congestion_control functionSam Jansen
From: "Sam Jansen" <sjansen@google.com> sysctl_tcp_congestion_control seems to have a bug that prevents it from actually calling the tcp_set_default_congestion_control function. This is not so apparent because it does not return an error and generally the /proc interface is used to configure the default TCP congestion control algorithm. This is present in 2.6.18 onwards and probably earlier, though I have not inspected 2.6.15--2.6.17. sysctl_tcp_congestion_control calls sysctl_string and expects a successful return code of 0. In such a case it actually sets the congestion control algorithm with tcp_set_default_congestion_control. Otherwise, it returns the value returned by sysctl_string. This was correct in 2.6.14, as sysctl_string returned 0 on success. However, sysctl_string was updated to return 1 on success around about 2.6.15 and sysctl_tcp_congestion_control was not updated. Even though sysctl_tcp_congestion_control returns 1, do_sysctl_strategy converts this return code to '0', so the caller never notices the error. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-11-18[TCP]: Fix TCP header misalignmentHerbert Xu
Indeed my previous change to alloc_pskb has made it possible for the TCP header to be misaligned iff the MTU is not a multiple of 4 (and less than a page). So I suspect the optimised IPsec MTU calculation is giving you just such an MTU :) This patch fixes it by changing alloc_pskb to make sure that the size is at least 32-bit aligned. This does not cause the problem fixed by the previous patch because max_header is always 32-bit aligned which means that in the SG/NOTSO case this will be a no-op. I thought about putting this in the callers but all the current callers are from TCP. If and when we get a non-TCP caller we can always create a TCP wrapper for this function and move the alignment over there.

2007-11-17x86: fix reboot with no keyboard attachedTruxton Fulton
Attempt to fix http://bugzilla.kernel.org/show_bug.cgi?id=8378 Hiroto Shibuya wrote to tell me that he has a VIA EPIA-EK10000 which suffers from the reboot problem when no keyboard is attached. My first patch works for him: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538 But the latest patch does not work for him : http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51 We found that it was necessary to also set the "disable keyboard" flag in the command byte, as the first patch was doing. The second patch tries to minimally modify the command byte, but it is not enough. Please consider this simple one-line patch to help people with low end VIA motherboards reboot when no keyboard is attached. Hiroto Shibuya has verified that this works for him (as I no longer have an afflicted machine). Additional discussion: Note that original patch from Truxton DOES disable keyboard and this has been in main tree since 2.6.14, thus it must have quite a bit of air time already. http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.14.y.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538 Note that he only mention "System flag" in the description and comment, but in the code, "disable keyboard" flag is set. outb(0x14, 0x60); /* set "System flag" */ In 2.6.23, he made a change to read the current byte and then mask the flags, but along this change, he only set the "System flag" and dropped the setting of "disable keyboard" flag. http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51 outb(cmd | 0x04, 0x60); /* set "System flag" */ So my request is to restore the setting of disable keyboard flag which has been there since 2.6.14 but disappeared in 2.6.23.
