ab074ad Linus Torvalds 19 October 2014, 23:25:56 UTC Merge git://git.infradead.org/users/eparis/audit Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static. Really minor stuff" * git://git.infradead.org/users/eparis/audit: (31 commits) audit: rename audit_log_remove_rule to disambiguate for trees audit: cull redundancy in audit_rule_change audit: WARN if audit_rule_change called illegally audit: put rule existence check in canonical order next: openrisc: Fix build audit: get comm using lock to avoid race in string printing audit: remove open_arg() function that is never used audit: correct AUDIT_GET_FEATURE return message type audit: set nlmsg_len for multicast messages. audit: use union for audit_field values since they are mutually exclusive audit: invalid op= values for rules audit: use atomic_t to simplify audit_serial() kernel/audit.c: use ARRAY_SIZE instead of sizeof/sizeof[0] audit: reduce scope of audit_log_fcaps audit: reduce scope of audit_net_id audit: arm64: Remove the audit arch argument to audit_syscall_entry arm64: audit: Add audit hook in syscall_trace_enter/exit() audit: x86: drop arch from __audit_syscall_entry() interface sparc: implement is_32bit_task sparc: properly conditionalize use of TIF_32BIT ... 19 October 2014, 23:25:56 UTC

e265314 David S. Miller 19 October 2014, 03:12:33 UTC sparc64: Do not define thread fpregs save area as zero-length array. This breaks the stack end corruption detection facility. What that facility does it write a magic value to "end_of_stack()" and checking to see if it gets overwritten. "end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is the beginning of the FPU register save area. So once the user uses the FPU, the magic value is overwritten and the debug checks trigger. Fix this by making the size explicit. Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we are limited to 7 levels of FPU state saves. So each FPU register set is 256 bytes, allocate 256 * 7 for the fpregs area.

84bd6d8 David S. Miller 19 October 2014, 03:03:09 UTC sparc64: Fix corrupted thread fault code. Every path that ends up at do_sparc64_fault() must install a valid FAULT_CODE_* bitmask in the per-thread fault code byte. Two paths leading to the label winfix_trampoline (which expects the FAULT_CODE_* mask in register %g4) were not doing so: 1) For pre-hypervisor TLB protection violation traps, if we took the 'winfix_trampoline' path we wouldn't have %g4 initialized with the FAULT_CODE_* value yet. Resulting in using the TLB_TAG_ACCESS register address value instead. 2) In the TSB miss path, when we notice that we are going to use a hugepage mapping, but we haven't allocated the hugepage TSB yet, we still have to take the window fixup case into consideration and in that particular path we leave %g4 not setup properly. Errors on this sort were largely invisible previously, but after commit 4ccb9272892c33ef1c19a783cfa87103b30c2784 ("sparc64: sun4v TLB error power off events") we now have a fault_code mask bit (FAULT_CODE_BAD_RA) that triggers due to this bug. FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS (see #1 above) and thus we get seemingly random bus errors triggered for user processes.

d974baa Andy Lutomirski 08 October 2014, 16:02:13 UTC x86,kvm,vmx: Preserve CR4 across VM entry CR4 isn't constant; at least the TSD and PCE bits can vary. TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks like it's correct. This adds a branch and a read from cr4 to each vm entry. Because it is extremely likely that consecutive entries into the same vcpu will have the same host cr4 value, this fixes up the vmcs instead of restoring cr4 after the fact. A subsequent patch will add a kernel-wide cr4 shadow, reducing the overhead in the common case to just two memory reads and a branch.

This code has been subsequently fixed in commit 11d4616bd07f (futex: revert back to the explicit waiter counting code). Both the original commit and the fix-up rely on get_futex_key_refs() to always imply a barrier. However, for private futexes, none of the cases in the switch statement of get_futex_key_refs() would be hit and the function completes without a memory barrier as required before checking the "waiters" in futex_wake() -> hb_waiters_pending(). The consequence is a race with a thread waiting on a futex on another CPU, allowing the waker thread to read "waiters == 0" while the waiter thread to have read "futex_val == locked" (in kernel). Without this fix, the problem (user space deadlocks) can be seen with Android bionic's mutex implementation on an arm64 multi-cluster system.

Such messages need to be to be delivered to the socket via a separate function, tipc_sk_mcast_rcv().

f47de06 Pravin B Shelar 17 October 2014, 04:55:45 UTC openvswitch: Create right mask with disabled megaflows If megaflows are disabled, the userspace does not send the netlink attribute OVS_FLOW_ATTR_MASK, and the kernel must create an exact match mask. sw_flow_mask_set() sets every bytes (in 'range') of the mask to 0xff, even the bytes that represent padding for struct sw_flow, or the bytes that represent fields that may not be set during ovs_flow_extract(). This is a problem, because when we extract a flow from a packet, we do not memset() anymore the struct sw_flow to 0. This commit gets rid of sw_flow_mask_set() and introduces mask_set_nlattr(), which operates on the netlink attributes rather than on the mask key. Using this approach we are sure that only the bytes that the user provided in the flow are matched. Also, if the parse_flow_mask_nlattrs() for the mask ENCAP attribute fails, we now return with an error. This bug is introduced by commit 0714812134d7dcadeb7ecfbfeb18788aa7e1eaac ("openvswitch: Eliminate memset() from flow_extract").

Switching only one commit root during a transaction is wrong because it leads the fs into an inconsistent state. All commit roots should be switched at once, at transaction commit time, otherwise backref walking can often miss important references that were only accessible through the old commit root. Plus, the root item for the snapshot's root wasn't getting updated and preventing the next transaction commit to do it. This made several users get into random corruption issues after creation of readonly snapshots. A regression test for xfstests will follow soon.

This bug affects live migration. xenkbd_disconnect_backend uses gnttab_end_foreign_access_ref to handle grant table entry which doesn't really free an entry. Thus every time we do xenkbd_resume, grant table entry increses by one. As an grant table entry occupies 8 bytes, an grant table page has at most 512 entries. Every 512 times we do xenkdb_resume, grant table pages increses by one. After around 3500 times of live migration, grant table pages will increase by 7, causing too many pages to populate and hitting max_pages limit when assigning pages.Thus assign_pages will fail, so will live migration.

2baa268 Steve French 27 September 2014, 07:19:01 UTC Remap reserved posix characters by default (part 3/3) This is a bigger patch, but its size is mostly due to a single change for how we check for remapping illegal characters in file names - a lot of repeated, small changes to the way callers request converting file names. The final patch in the series does the following: 1) changes default behavior for cifs to be more intuitive. Currently we do not map by default to seven reserved characters, ie those valid in POSIX but not in NTFS/CIFS/SMB3/Windows, unless a mount option (mapchars) is specified. Change this to by default always map and map using the SFM maping (like the Mac uses) unless the server negotiates the CIFS Unix Extensions (like Samba does when mounting with the cifs protocol) when the remapping of the characters is unnecessary. This should help SMB3 mounts in particular since Samba will likely be able to implement this mapping with its new "vfs_fruit" module as it will be doing for the Mac. 2) if the user specifies the existing "mapchars" mount option then use the "SFU" (Microsoft Services for Unix, SUA) style mapping of the seven characters instead. 3) if the user specifies "nomapposix" then disable SFM/MAC style mapping (so no character remapping would be used unless the user specifies "mapchars" on mount as well, as above). 4) change all the places in the code that check for the superblock flag on the mount which is set by mapchars and passed in on all path based operation and change it to use a small function call instead to set the mapping type properly (and check for the mapping type in the cifs unicode functions) Signed-off-by: Steve French <smfrench@gmail.com> 16 October 2014, 20:20:20 UTC

b693855 Steve French 25 September 2014, 18:20:05 UTC Allow conversion of characters in Mac remap range. Part 1 This allows directory listings to Mac to display filenames correctly which have been created with illegal (to Windows) characters in their filename. It does not allow converting the other direction yet ie opening files with these characters (followon patch). There are seven reserved characters that need to be remapped when mounting to Windows, Mac (or any server without Unix Extensions) which are valid in POSIX but not in the other OS. : \ < > ? * | We used the normal UCS-2 remap range for this in order to convert this to/from UTF8 as did Windows Services for Unix (basically add 0xF000 to any of the 7 reserved characters), at least when the "mapchars" mount option was specified. Mac used a very slightly different "Services for Mac" remap range 0xF021 through 0xF027. The attached patch allows cifs.ko (the kernel client) to read directories on macs containing files with these characters and display their names properly. In theory this even might be useful on mounts to Samba when the vfs_catia or new "vfs_fruit" module is loaded. Currently the 7 reserved characters look very strange in directory listings from cifs.ko to Mac server. This patch allows these file name characters to be read (requires specifying mapchars on mount). Two additional changes are needed: 1) Make it more automatic: a way of detecting enough info so that we know to try to always remap these characters or not. Various have suggested that the SFM approach be made the default when the server does not support POSIX Unix extensions (cifs mounts to Samba for example) so need to make SFM remapping the default unless mapchars (SFU style mapping) specified on mount or no mapping explicitly requested or no mapping needed (cifs mounts to Samba). 2) Adding a patch to map the characters the other direction (ie UTF-8 to UCS-2 on open).

This also helps enable running additional xfstests over SMB3 (since some xfstests directly or indirectly require symlink support).

db8b631 Steve French 22 September 2014, 10:13:55 UTC Allow mknod and mkfifo on SMB2/SMB3 mounts The "sfu" mount option did not work on SMB2/SMB3 mounts. With these changes when the "sfu" mount option is passed in on an smb2/smb2.1/smb3 mount the client can emulate (and recognize) fifo and device (character and device files). In addition the "sfu" mount option should not conflict with "mfsymlinks" (symlink emulation) as we will never create "sfu" style symlinks, but using "sfu" mount option will allow us to recognize existing symlinks, created with Microsoft "Services for Unix" (SFU and SUA). To enable the "sfu" mount option for SMB2/SMB3 the calling syntax of the generic cifs/smb2/smb3 sync_read and sync_write protocol dependent function needed to be changed (we don't have a file struct in all cases), but this actually ended up simplifying the code a little.
