* fuse: pass open flags to read and writeMiklos Szeredi2007-11-29
| | | | | | | | | | | | Some open flags (O_APPEND, O_DIRECT) can be changed with fcntl(F_SETFL, ...) after open, but fuse currently only sends the flags to userspace in open. To make it possible to correcly handle changing flags, send the current value to userspace in each read and write.

* x86_64 EFI boot support: EFI frame buffer driverHuang, Ying2007-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds Graphics Output Protocol support to the kernel. UEFI2.0 spec deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output Protocol (GOP) is produced. Therefore, the boot loader needs to query the UEFI firmware with appropriate Output Protocol and pass the video information to the kernel. As a result of GOP protocol, an EFI framebuffer driver is needed for displaying console messages. The patch adds a EFI framebuffer driver. The EFI frame buffer driver in this patch is based on the Intel Mac framebuffer driver. The ELILO bootloader takes care of passing the video information as appropriate for EFI firmware. The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI platform.

* fix up ext2_fs.h for userspace after reservations backportTobias Poschwatta2007-11-29
| | | | | | | | | | | | | | In commit a686cd898bd999fd026a51e90fb0a3410d258ddb: "Val's cross-port of the ext3 reservations code into ext2." include/linux/ext2_fs.h got a new function whose return value is only defined if __KERNEL__ is defined.

* Fix <linux/kd.h> usage in userspaceDavid Woodhouse2007-11-29
| | | | | | | | | | | | | | | | For reasons unclear to me, glibc's <sys/kd.h> deliberately defeats the attempt we make in <linux/kd.h> to include <linux/types.h> For now, change the one instance of __u32 to 'unsigned int' instead because it's breaking userspace. We should probably also remove our inclusion of <linux/types.h>, since we don't use it -- but that's not a change to make in -rc.

* PNP: increase the maximum number of resourcesZhao Yakui2007-11-29
| | | | | | | | | | | | | | | | | | On some systems the number of resources(IO,MEM) returnedy by PNP device is greater than the PNP constant, for example motherboard devices. It brings that some resources can't be reserved and resource confilicts. This will cause PCI resources are assigned wrongly in some systems, and cause hang. This is a regression since we deleted ACPI motherboard driver and use PNP system driver.

| * | [SKBUFF]: Free old skb properly in skb_morphHerbert Xu2007-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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...

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.

Also see: http://bugzilla.kernel.org/show_bug.cgi?id=6761 [ mingo@elte.hu: added patch description and made it backwards compatible ] NOTE: the new flag is defined 0xa001 so that it returns -EINVAL on older kernels - this way glibc can use it safely.

CSYNC • SSYNC • LCx = • LTx = (only when LCx is non-zero) • LBx = (only when LCx is non-zero) When this problem occurs, a variety of incorrect things could happen, including an illegal instruction exception. Additional errors could show up as an exception, a hardware error, or an instruction that is valid but different than the one that was expected. WORKAROUND: Place a cli before all SSYNC, CSYNC, "LCx =", "LTx =", and "LBx =" instructions to disable interrupts, and place an sti after each of these instructions to re-enable interrupts. When these instructions are executed in code that is already non-interruptible, the problem will not occur.
