* [PATCH] x86_64 ia32 vDSO: use VM_ALWAYSDUMPRoland McGrath2007-01-262-49/+7
| | | | | | | | | | | | | | | | | | This patch fixes ia32 core dumps on x86_64 to include just one phdr for the vDSO vma. Currently it writes a confused format with two phdrs for the address, one without contents and one with. This patch removes the special-case core writing macros for the ia32 vDSO. Instead, it uses VM_ALWAYSDUMP in the vma. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO, consistent with fixed native i386 core dumps.

* [PATCH] i386 vDSO: use VM_ALWAYSDUMPRoland McGrath2007-01-264-52/+49
| | | | | | | | | | | | | | | | | | | | | | | This patch fixes core dumps to include the vDSO vma, which is left out now. It removes the special-case core writing macros, which were not doing the right thing for the vDSO vma anyway. Instead, it uses VM_ALWAYSDUMP in the vma; there is no need for the fixmap page to be installed. It handles the CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from get_gate_vma after real vmas in the same way the /proc/PID/maps code does. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO. I made the change to add them in the first place, but in turned out that nothing ever wanted them there since the advent of NT_AUXV. It's cleaner to leave them out, and just let the phdrs inside the vDSO image speak for themselves.

* [PATCH] Fix CONFIG_COMPAT_VDSORoland McGrath2007-01-265-4/+13
| | | | | | | | | | | | | | | | | | | | I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely. But if it's there, it should work properly. Currently it's quite haphazard: both real vma and fixmap are mapped, both are put in the two different AT_* slots, sysenter returns to the vma address rather than the fixmap address, and core dumps yet are another story. This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap area consistently. This makes it actually compatible with what the old vdso implementation did.

| | | | | | | | | | | | | Currently the spi mode can be set to the wrong mode if you are switching from any mode other than mode 0.

* [PATCH] KVM: SVM: Propagate cpu shutdown events to userspaceJoerg Roedel2007-01-262-0/+16
| | | | | | | | | | | | This patch implements forwarding of SHUTDOWN intercepts from the guest on to userspace on AMD SVM. A SHUTDOWN event occurs when the guest produces a triple fault (e.g. on reboot). This also fixes the bug that a guest reboot actually causes a host reboot under some circumstances.

| | | | | | | | | | | | | | | | | | | Check pte permission bits in walk_addr(), instead of scattering the checks all over the code. This has the following benefits: 1. We no longer set the accessed bit for accessed which fail permission checks. 2. Setting the accessed bit is simplified. 3. Under some circumstances, we used to pretend a page fault was fixed when it would actually fail the access checks. This caused an unnecessary vmexit. 4. The error code for guest page faults is now correct. The fix helps netbsd further along booting, and allows kvm to pass the new mmu testsuite.

* Write back inode data pages even when the inode itself is lockedLinus Torvalds2007-01-261-1/+12
| | | | | | | | | | | | | | | | | | In __writeback_single_inode(), when we find a locked inode and we're not doing a data-integrity sync, we used to just skip writing entirely, since we didn't want to wait for the inode to unlock. However, there's really no reason to skip writing the data pages, which are likely to be the the bulk of the dirty state anyway (and the main reason why writeback was started for the non-data-integrity case, of course!)

* Resurrect 'try_to_free_buffers()' VM hackeryLinus Torvalds2007-01-262-8/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not pretty, but it appears that ext3 with data=journal will clean pages without ever actually telling the VM that they are clean. This, in turn, will result in the VM (and balance_dirty_pages() in particular) to never realize that the pages got cleaned, and wait forever for an event that already happened. Technically, this seems to be a problem with ext3 itself, but it used to be hidden by 'try_to_free_buffers()' noticing this situation on its own, and just working around the filesystem problem. This commit re-instates that hack, in order to avoid a regression for the 2.6.20 release. This fixes bugzilla 7844: http://bugzilla.kernel.org/show_bug.cgi?id=7844 Peter Zijlstra points out that we should probably retain the debugging code that this removes from cancel_dirty_page(), and I agree, but for the imminent release we might as well just silence the warning too (since it's not a new bug: anything that triggers that warning has been around forever).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 8e3d8433d8c22ca6c42cba4a67d300c39aae7822 ([NET]: MIPS checksum annotations and cleanups) broke 64-bit MIPS. The problem is the commit replaces some unsigned long with __be32. On 64bit MIPS, a __be32 (i.e. unsigned int) value is represented as a sign-extented 32-bit value in a 64-bit argument register. So the address 192.168.0.1 (0xc0a80001) is passed as 0xffffffffc0a80001 to csum_tcpudp_nofold() but the asm code in the function expects 0x00000000c0a80001, therefore it returns a wrong checksum.

On most architectures it doesn't really matter since we don't have any tables with names that long in the kernel and the structure layout didn't change because of alignment requirements of following members. On CRIS however (and other architectures that don't align data) this changed the structure layout and thus broke compatibility with old iptables binaries. Changing it back will break compatibility with binaries compiled against recent kernels again, but since the breakage has only been there for three releases this seems like the better choice.

The server side sets IPV6_RECVPKTINFO on a listening socket, and the client side just sends a message to the server. Then the kernel panic occurs on the server. (If you need the test program, please let me know. I can provide it.) This problem happens because a skb is forcibly freed in tcp_rcv_state_process(). When a socket in listening state(TCP_LISTEN) receives a syn packet, then tcp_v6_conn_request() will be called from tcp_rcv_state_process(). If the tcp_v6_conn_request() successfully returns, the skb would be discarded by __kfree_skb(). However, in case of a listening socket which was already set IPV6_RECVPKTINFO, an address of the skb will be stored in treq->pktopts and a ref count of the skb will be incremented in tcp_v6_conn_request(). But, even if the skb is still in use, the skb will be freed. Then someone still using the freed skb will cause the kernel panic. I suggest to use kfree_skb() instead of __kfree_skb().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent hashing introduced an off-by-one bug in policy list insertion. Instead of adding after the last entry with a lesser or equal priority, we're adding after the successor of that entry. This patch fixes this and also adds a warning if we detect a duplicate entry in the policy list. This should never happen due to this if clause.
