2010-04-20KVM: VMX: Save/restore rflags.vm correctly in real modeAvi Kivity
Currently we set eflags.vm unconditionally when entering real mode emulation through virtual-8086 mode, and clear it unconditionally when we enter protected mode. The means that the following sequence KVM_SET_REGS (rflags.vm=1) KVM_SET_SREGS (cr0.pe=1) Ends up with rflags.vm clear due to KVM_SET_SREGS triggering enter_pmode(). Fix by shadowing rflags.vm (and rflags.iopl) correctly while in real mode: reads and writes to those bits access a shadow register instead of the actual register.

2010-04-20KVM: allow bit 10 to be cleared in MSR_IA32_MC4_CTLAndre Przywara
There is a quirk for AMD K8 CPUs in many Linux kernels (see arch/x86/kernel/cpu/mcheck/mce.c:__mcheck_cpu_apply_quirks()) that clears bit 10 in that MCE related MSR. KVM can only cope with all zeros or all ones, so it will inject a #GP into the guest, which will let it panic. So lets add a quirk to the quirk and ignore this single cleared bit. This fixes -cpu kvm64 on all machines and -cpu host on K8 machines with some guest Linux kernels. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2010-04-19rmap: add exclusively owned pages to the newest anon_vmaRik van Riel
The recent anon_vma fixes cause many anonymous pages to end up in the parent process anon_vma, even when the page is exclusively owned by the current process. Adding exclusively owned anonymous pages to the top anon_vma reduces rmap scanning overhead, especially in workloads with forking servers. This patch adds a parameter to __page_set_anon_rmap that can be used to indicate whether or not the added page is exclusively owned by the current process. Pages added through page_add_new_anon_rmap are exclusively owned by the current process, and can be added to the top anon_vma. Pages added through page_add_anon_rmap can be either shared or exclusively owned, so we do the conservative thing and add it to the oldest anon_vma. A next step would be to add the exclusive parameter to page_add_anon_rmap, to be used from functions where we do know for sure whether a page is exclusively owned.

2010-04-19ecryptfs: fix use with tmpfs by removing d_drop from ecryptfs_destroy_inodeJeff Mahoney
Since tmpfs has no persistent storage, it pins all its dentries in memory so they have d_count=1 when other file systems would have d_count=0. ->lookup is only used to create new dentries. If the caller doesn't instantiate it, it's freed immediately at dput(). ->readdir reads directly from the dcache and depends on the dentries being hashed. When an ecryptfs mount is mounted, it associates the lower file and dentry with the ecryptfs files as they're accessed. When it's umounted and destroys all the in-memory ecryptfs inodes, it fput's the lower_files and d_drop's the lower_dentries. Commit 4981e081 added this and a d_delete in 2008 and several months later commit caeeeecf removed the d_delete. I believe the d_drop() needs to be removed as well. The d_drop effectively hides any file that has been accessed via ecryptfs from the underlying tmpfs since it depends on it being hashed for it to be accessible. I've removed the d_drop on my development node and see no ill effects with basic testing on both tmpfs and persistent storage. As a side effect, after ecryptfs d_drops the dentries on tmpfs, tmpfs BUGs on umount. This is due to the dentries being unhashed. tmpfs->kill_sb is kill_litter_super which calls d_genocide to drop the reference pinning the dentry. It skips unhashed and negative dentries, but shrink_dcache_for_umount_subtree doesn't. Since those dentries still have an elevated d_count, we get a BUG(). This patch removes the d_drop call and fixes both issues.

2010-04-19ecryptfs: fix error code for missing xattrs in lower fsChristian Pulvermacher
If the lower file system driver has extended attributes disabled, ecryptfs' own access functions return -ENOSYS instead of -EOPNOTSUPP. This breaks execution of programs in the ecryptfs mount, since the kernel expects the latter error when checking for security capabilities in xattrs.

2010-04-19eCryptfs: Decrypt symlink target for stat sizeTyler Hicks
Create a getattr handler for eCryptfs symlinks that is capable of reading the lower target and decrypting its path. Prior to this patch, a stat's st_size field would represent the strlen of the encrypted path, while readlink() would return the strlen of the decrypted path. This could lead to confusion in some userspace applications, since the two values should be equal. https://bugs.launchpad.net/bugs/524919 Reported-by: Loïc Minier <loic.minier@canonical.com> Cc: stable@kernel.org Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>

2010-04-17[LogFS] Set s_bdiJoern Engel
Since 32a88aa1 sync() was turned into a NOP for logfs. Worse, sync() would not return an error, giving the illusion that writeout had actually happened. Afaics jffs2 was broken as well. Signed-off-by: Joern Engel <joern@logfs.org>
2010-04-17drivers/pcmcia: Add missing local_irq_restoreJulia Lawall
Use local_irq_restore in this error-handling case just like in the one just below. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression E1; identifier f; @@ f (...) { <+... * local_irq_save (E1,...); ... when != E1 * return ...; ...+> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2010-04-17serial_cs: MD55x support (PCMCIA GPRS/EDGE modem) (kernel 2.6.33)Timur Maximov
Many PCMCIA GPRS modems like: Onda Edge N100E, Novaway PC98 (OEM SPC98Z), Rovermate Edgus Adaptmate-039 and others have same construction and identification: lspcmcia -vvv Product Name: Generic Modem: MD55x 1.00 Serial number: xxxxx-xxx Identification: manf_id: 0x015d card_id: 0x4c45 function: 2 (serial) prod_id(1): "Generic" (0xc49e4731) prod_id(2): "Modem: MD55x" (0x8913b110) prod_id(3): "1.00" (0x83dbf271) prod_id(4): "Serial number: xxxxx-xxx" (0x73ee9514) Serial connection to GSM module based on Elan VPU16551 PCMCIA UART with datasheet recommeded 14.7456MHz crystal oscillator. By default serial_cs set UART clock == 1843200 Hz For correct work need set clock 14745600 Hz. This quirk already present in driver, only need add device in quirk list.
