commit 9c2d2056 upstream. When calling vfs_unlink() on the lower dentry, d_delete() turns the dentry into a negative dentry when the d_count is 1. This eventually caused a NULL pointer deref when a read() or write() was done and the negative dentry's d_inode was dereferenced in ecryptfs_read_update_atime() or ecryptfs_getxattr(). Placing mutt's tmpdir in an eCryptfs mount is what initially triggered the oops and I was able to reproduce it with the following sequence: open("/tmp/upper/foo", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW, 0600) = 3 link("/tmp/upper/foo", "/tmp/upper/bar") = 0 unlink("/tmp/upper/foo") = 0 open("/tmp/upper/bar", O_RDWR|O_CREAT|O_NOFOLLOW, 0600) = 4 unlink("/tmp/upper/bar") = 0 write(4, "eCryptfs test\n"..., 14 <unfinished ...> +++ killed by SIGKILL +++ https://bugs.launchpad.net/ecryptfs/+bug/387073Reported-by:

commit 38919598 upstream. When searching through the global authentication tokens for a given key signature, verify that a matching key has not been revoked and has not expired. This allows the `keyctl revoke` command to be properly used on keys in use by eCryptfs. Acked-by:

commit df6ad33b upstream. Returns -ENOTSUPP when attempting to use filename encryption with something other than a password authentication token, such as a private token from openssl. Using filename encryption with a userspace eCryptfs key module is a future goal. Until then, this patch handles the situation a little better than simply using a BUG_ON(). Acked-by:

commit ac22ba23 upstream. If the lower inode is read-only, don't attempt to open the lower file read/write and don't hand off the open request to the privileged eCryptfs kthread for opening it read/write. Instead, only try an unprivileged, read-only open of the file and give up if that fails. This patch fixes an oops when eCryptfs is mounted on top of a read-only mount. Acked-by:

commit b0105eae upstream. Returns an error when an unrecognized cipher code is present in a tag 3 packet or an ecryptfs_crypt_stat cannot be initialized. Also sets an crypt_stat->tfm error pointer to NULL to ensure that it will not be incorrectly freed in ecryptfs_destroy_crypt_stat(). Acked-by:

commit 580be083 upstream. In theory it could happen that on one CPU we initialize a new inode but clearing of I_NEW | I_LOCK gets reordered before some of the initialization. Thus on another CPU we return not fully uptodate inode from iget_locked(). This seems to fix a corruption issue on ext3 mounted over NFS.

commit d08ebedd upstream. Some time ago, I have send a patch to the mmc_spi subsystem changing the error codes. This was after a discussion with Pierre about using EINVAL only for non-recoverable errors. This patch was accepted as http://git.kernel.org/linus/fdd858db7113ca64132de390188d7ca00701013d Unfortunately, several weeks later, I realized that this patch has opened a little can of worms because there are SD cards on the market which a) claim that they support the switch command AND b) refuse to execute this command if operating in SPI mode. So, such a card would get unusuable in an embedded linux system in SPI mode, because the init sequence terminates with an error. This patch adds the missing error codes to the caller of the switch command and restores the old behaviour to fail gracefully if these commands can not execute. Signed-off-by:

commit a9ece53c upstream. Commit b478b782 "kallsyms, tracing: output more proper symbol name" introduces a "bugfix" that introduces a segfault in kallsyms in my configurations. The cause is the introduction of prefix_underscores_count() which attempts to count underscores, even in symbols that do not have them. As a result, it just uselessly runs past the end of the buffer until it crashes: CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 KSYM .tmp_kallsyms1.S /bin/sh: line 1: 16934 Done sh-linux-gnu-nm -n .tmp_vmlinux1 16935 Segmentation fault | scripts/kallsyms > .tmp_kallsyms1.S make: *** [.tmp_kallsyms1.S] Error 139 This simplifies the logic and just does a straightforward count.

commit 2ddce3fd upstream. Attempting to unload a framebuffer module calls unregister_framebuffer() which in turn gets fbcon to release it. If fbcon has no framebuffers linked to a console, it will also unbind itself from the console driver. However, if fbcon never registered itself as a console driver, the unbind will fail causing the framebuffer device entry to persist. In most cases this failure will result in an oops when attempting to access the now non-existent device. This patch ensures that the fbcon unbind request will succeed even if a bind was never done. It tracks if a successful bind ever occurred & will only attempt to unbind if needed. If there never was a bind, it simply returns with no error. Signed-off-by:

commit 6da25bf5 upstream. X40 (firmware 1V) and T41 (firmware 1R) have been confirmed to work well with the new defaults, so we can stop pestering people to confirm that fact.

It is best to have at least one more firmware type confirmed for Radeon 9xxx and Intel GMA-2 ThinkPads before removing the confirmation requests entirely. Reported-by:

commit 80938332 upstream. Currently we are not including randomized stack size when calculating mmap_base address in arch_pick_mmap_layout for topdown case. This might cause that mmap_base starts in the stack reserved area because stack is randomized by 1GB for 64b (8MB for 32b) and the minimum gap is 128MB. If the stack really grows down to mmap_base then we can get silent mmap region overwrite by the stack values. Let's include maximum stack randomization size into MIN_GAP which is used as the low bound for the gap in mmap. Signed-off-by:

commit 90950a25 upstream. On a Compaq Presario V3000 laptop (NVIDIA MCP51 chipset), pata_amd selects PIO0 mode for the PATA DVD-RAM drive instead of MWDMA2 which it supports: ata4.00: ATAPI: HL-DT-ST DVDRAM GSA-4084N, KQ09, max MWDMA2 ata4: nv_mode_filter: 0x39f&0x7001->0x1, BIOS=0x0 (0x0) ACPI=0x7001 (60:600:0x11) ata4.00: configured for PIO0 For some reason, the BIOS-set UDMA configuration returns 0 and the ACPI _GTM reports that UDMA2 and PIO0 are enabled. This causes nv_mode_filter to end up allowing only PIO0 and UDMA0-2. Since the drive doesn't support UDMA we end up using PIO0. Since the controllers should always support PIO4, MWDMA2 and UDMA2 regardless of what cable type is used, let's make sure we don't filter out these modes regardless of what wacky settings the BIOS is using.

commit 46db2f86 upstream. The SLB can change sizes across a live migration, which was not being handled, resulting in possible machine crashes during migration if migrating to a machine which has a smaller max SLB size than the source machine. Fix this by first reducing the SLB size to the minimum possible value, which is 32, prior to migration. Then during the device tree update which occurs after migration, we make the call to ensure the SLB gets updated. Also add the slb_size to the lparcfg output so that the migration tools can check to make sure the kernel has this capability before allowing migration in scenarios where the SLB size will change.

commit 07708c4a upstream. So far unprivileged guest callers running in ring 3 can issue, e.g., MMU hypercalls. Normally, such callers cannot provide any hand-crafted MMU command structure as it has to be passed by its physical address, but they can still crash the guest kernel by passing random addresses. To close the hole, this patch considers hypercalls valid only if issued from guest ring 0. This may still be relaxed on a per-hypercall base in the future once required. Signed-off-by:

commit a20316d2 upstream. The use of __pa() to calculate the address of a C-visible symbol is wrong, and can lead to unpredictable results. See arch/x86/include/asm/page.h for details. It should be replaced with __pa_symbol(), that does the correct math here, by taking relocations into account. This ensures the correct wallclock data structure physical address is passed to the hypervisor. Signed-off-by:

commit 0a79b009 upstream. Debug registers may only be accessed from cpl 0. Unfortunately, vmx will code to emulate the instruction even though it was issued from guest userspace, possibly leading to an unexpected trap later. Signed-off-by:

commit 6ba66178 upstream. Commit b8bcfe99 made paravirt pte updates synchronous in interrupt context. Unfortunately the KVM pv mmu code caches the lazy/nonlazy mode internally, so a pte update from interrupt context during a lazy mmu operation can be batched while it should be performed synchronously. https://bugzilla.redhat.com/show_bug.cgi?id=518022 Drop the internal mode variable and use paravirt_get_lazy_mode(), which returns the correct state.

commit 7929eb9c upstream. Let's suppose a highmem page is kmap'd with kmap(). A pkmap entry is used, the page mapped to it, and the virtual cache is dirtied. Then kunmap() is used which does virtually nothing except for decrementing a usage count. Then, let's suppose the _same_ page gets mapped using kmap_atomic(). It is therefore mapped onto a fixmap entry instead, which has a different virtual address unaware of the dirty cache data for that page sitting in the pkmap mapping. Fortunately it is easy to know if a pkmap mapping still exists for that page and use it directly with kmap_atomic(), thanks to kmap_high_get(). And actual testing with a printk in the added code path shows that this condition is actually met *extremely* frequently. Seems that we've been quite lucky that things have worked so well with highmem so far. Signed-off-by:

commit fa526d0d upstream. Fix address passed to cpa_flush_range() when changing page attributes from WB to UC. The address (*addr) is modified by __change_page_attr_set_clr(). The result is that the pages being flushed start at the _end_ of the changed range instead of the beginning. This should be considered for 2.6.30-stable and 2.6.31-stable. Signed-off-by:
