You wouldn't think that doing an ALIGN() macro that aligns something up to a power-of-two boundary would be likely to have bugs, would you? But hey, in the wonderful world of mixing integer types, you have to be careful. This just makes sure that the alignment is interpreted in the same type as the thing to be aligned. Thanks to Roland Dreier, who noticed that the amso1100 driver got broken by the previous fix (that just extended the mask to "unsigned long", but was still broken in "unsigned long long" - it just happened to be the same on 64-bit architectures). See commit 4c8bd7ee for the history of bugs here... Acked-by:

When application uses XFRM_MSG_GETSA to get state entry through netlink socket and kernel has no matching one, the application expects reply message with error status by kernel. Kernel doesn't send the message back in the case of Mobile IPv6 route optimization protocols (i.e. routing header or destination options header). This is caused by incorrect return code "0" from net/xfrm/xfrm_user.c(xfrm_user_state_lookup) and it makes kernel skip to acknowledge at net/netlink/af_netlink.c(netlink_rcv_skb). This patch fix to reply ESRCH to application. Signed-off-by:

Make udp_encap_rcv use pskb_may_pull IPsec with NAT-T breaks on some notebooks using the latest e1000 chipset, when header split is enabled. When receiving sufficiently large packets, the driver puts everything up to and including the UDP header into the header portion of the skb, and the rest goes into the paged part. udp_encap_rcv forgets to use pskb_may_pull, and fails to decapsulate it. Instead, it passes it up it to the IKE daemon. Signed-off-by:

H.323 connection tracking code calls ip_ct_refresh_acct() when processing RCFs and URQs but passes NULL as the skb. When CONFIG_IP_NF_CT_ACCT is enabled, the connection tracking core tries to derefence the skb, which results in an obvious panic. A similar fix was applied on the SIP connection tracking code some time ago. Signed-off-by:

Paolo 'Blaisorblade' Giarrusso authored
Reimplement execvp for our purposes - after we call fork() it is fundamentally unsafe to use the kernel allocator - current is not valid there. So we simply pass to our modified execvp() a preallocated buffer. This fixes a real bug and works very well in testing (I've seen indirectly warning messages from the forked thread - they went on the pipe connected to its stdout and where read as a number by UML, when calling read_output(). I verified the obtained number corresponded to "BUG:"). The added use of __cant_sleep() is not a new bug since __cant_sleep() is already used in the same function - passing an atomicity parameter would be better but it would require huge change, stating that this function must not be called in atomic context and can sleep is a better idea (will make sure of this gradually).

This is a bug. When checking for ati_remote->outbuf we free freeing ati_remote->inbuf so we end up freeing ati_remote->inbuf twice. Also the checks for 'ati_remote->inbuf != NULL' and 'ati_remote->outbuf != NULL' are redundant as usb_buffer_free() does this. Signed-off-by:

Make it break or warn if you pass to spin_lock_irqsave() and friends something different from "unsigned long flags;". Suprisingly large amount of these was caught by recent commit c53421b1 and others. Idea is largely from FRV typechecking. Suggestions from Andrew Morton. All stupid typos in first version fixed. Passes allmodconfig on i386, x86_64, alpha, arm as well as my usual config. Note #1: checking with sparse is still needed, because a driver can save and pass around flags or something. So far patch is very intrusive. Note #2: techically, we should break only if sizeof(flags) < sizeof(unsigned long), however, the more pain for getting suspicious code into kernel, the better.

This patch removes a module_exit function that sgiioc4 should not have had. It seems that the IDE layer doesn't support submodule unloading. sgiioc4 was the only driver in drivers/ide/pci that had an exit function. After an unload, the devices would stay around and the next attempt to reference would crash... Signed-off-by:

I got a lockdep warning when running "rtctest" so I though it'd be good to see what was up. - The warning was for rtc->irq_task_lock, gotten from rtc_update_irq() by irq handlerss ... but in a handful of other cases, grabbed without blocking IRQs. - Some callers to rtc_update_irq() were not ensuring IRQs were blocked, yet the routine expects that; make sure all callers block IRQs. It would appear that RTC API tests haven't been part of anyone's kernel regression test suite recently, at least not with lockdep running. Signed-off-by:

The RTC framework has an irq_set_freq() method that should be used to manage the periodic IRQ frequency, but the current ioctl logic doesn't know how to do that. This patch teaches it how. This means that drivers implementing irq_set_freq() will automatically support RTC_IRQP_{READ,SET} ioctls; that logic doesn't need duplication within the driver.

Fix bug in certain error paths of lookup routines. The request object was reused for sending FORGET, which is illegal. This bug could cause an Oops in 2.6.18. In earlier versions it might silently corrupt memory, but this is very unlikely. These error paths are never triggered by libfuse, so this wasn't noticed even with the 2.6.18 kernel, only with a filesystem using the raw kernel interface.

Fix bug 7401. Handle more than one source dir or file list to the initramfs gen scripts. The Kconfig help for INITRAMFS_SOURCE claims that you can specify multiple space-separated sources in order to allow unprivileged users to build an image. There are two bugs in the current implementation that prevent this from working. First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it obviously can't open. Second, gen_initramfs_list.sh -l outputs multiple definitions for deps_initramfs -- one for each argument. Signed-off-by:
