* kexec: fix memory leak in function kimage_normal_allocZhang Yanfei2013-02-271-8/+10
| | | | | | | | | | | | | If kimage_normal_alloc() fails to alloc pages for image->swap_page, it should call kimage_free_page_list() to free allocated pages in image->control_pages list before it frees image.

* kexec: prevent double free on image allocation failureSasha Levin2013-02-271-2/+0
| | | | | | | | | | | | | | | If kimage_normal_alloc() fails to initialize an allocated kimage, it will free the image but would still set 'rimage', as a result kexec_load will try to free it again. This would explode as part of the freeing process is accessing internal members which point to uninitialized memory. Signed-off-by: Sasha Levin <sasha.levin@oracle.com> Cc: "Eric W.

* kexec: export PG_hwpoison flag into vmcoreinfoMitsuhiro Tanino2013-02-271-0/+3
| | | | | | | | | | | | | | | | | | This patch exports a PG_hwpoison into vmcoreinfo when CONFIG_MEMORY_FAILURE is defined. "makedumpfile" needs to read information of memory, such as 'mem_section', 'zone', 'pageflags' from vmcore. We introduce a function into "makedumpfile" to exclude hwpoison page from vmcore dump. In order to introduce this function, PG_hwpoison flag have to export into vmcoreinfo. Signed-off-by: Mitsuhiro Tanino <mitsuhiro.tanino.gm@hitachi.com> Acked-by: "Eric W.

* kexec: add the values related to buddy system for filtering free pages.Atsushi Kumagai2013-02-271-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tAdd adds the values related to buddy system to vmcoreinfo data so that makedumpfile (dump filtering command) can filter out all free pages with the new logic. It's faster than the current logic because it can distinguish free page by analyzing page structure at the same time as filtering for other unnecessary pages (e.g. anonymous page). OTOH, the current logic has to trace free_list to distinguish free pages while analyzing page structure to filter out other unnecessary pages. The new logic uses the fact that buddy page is marked by _mapcount == PAGE_BUDDY_MAPCOUNT_VALUE. But, _mapcount shares its memory with other fields for SLAB/SLUB when PG_slab is set, so we need to check if PG_slab is set or not before looking up _mapcount value. And we can get the order of buddy system from private field. To sum it up, the values below are required for this logic. Required values: - OFFSET(page._mapcount) - OFFSET(page.private) - NUMBER(PG_slab) - NUMBER(PAGE_BUDDY_MAPCOUNT_VALUE) Changelog from v1 to v2: 1. remove SIZE(pageflags) The new logic was changed after I sent v1 patch. Accordingly, SIZE(pageflags) has been unnecessary for makedumpfile. What's makedumpfile: makedumpfile creates a small dumpfile by excluding unnecessary pages for the analysis. To distinguish unnecessary pages, makedumpfile gets the vmcoreinfo data which has the minimum debugging information only for dump filtering.

* signal: allow to send any siginfo to itselfAndrey Vagin2013-02-271-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea is simple. We need to get the siginfo for each signal on checkpointing dump, and then return it back on restore. The first problem is that the kernel doesn't report complete siginfos to userspace. In a signal handler the kernel strips SI_CODE from siginfo. When a siginfo is received from signalfd, it has a different format with fixed sizes of fields. The interface of signalfd was extended. If a signalfd is created with the flag SFD_RAW, it returns siginfo in a raw format. rt_sigqueueinfo looks suitable for restoring signals, but it can't send siginfo with a positive si_code, because these codes are reserved for the kernel. In the real world each person has right to do anything with himself, so I think a process should able to send any siginfo to itself. This patch: The kernel prevents sending of siginfo with positive si_code, because these codes are reserved for kernel. I think we can allow a task to send such a siginfo to itself. This operation should not be dangerous. This functionality is required for restoring signals in checkpoint/restart.

| | | | | | | | | | | | | | | | | | | | | | | | | | | There is no documented methods to mark FAT as dirty. Unofficially MS started to use reserved Byte in boot sector for this purpose, at least since Win 2000. With Win 7 user is warned if fs is dirty and asked to clean it. Different versions of Win, handle it in different ways, but always have same meaning: - Win 2000 and XP, set it on write operations and remove it after operation was finnished - Win 7, set dirty flag on first write and remove it on umount. We will do it as follows: - set dirty flag on mount. If fs was initially dirty, warn user, remember it and do not do any changes to boot sector. - clean it on umount. If fs was initially dirty, leave it dirty. - do not do any thing if fs mounted read-only. - TODO: leave fs dirty if we found some error after mount.

* hfsplus: fix issue with unzeroed unused b-tree nodesVyacheslav Dubeyko2013-02-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fsck_hfs (under MacOS X) complains about unzeroed unused b-tree nodes after deletion of folders' tree under Linux. SYMPTOMS: Running Disk Utiltiy's "Verify Disk" on "test" gives the following: Verifying volume “Test” Checking file systemChecking Journaled HFS Plus volume. Checking extents overflow file. Checking catalog file. Unused node is not erased (node = 3111) Checking multi-linked files. Checking catalog hierarchy. Checking extended attributes file. Checking volume bitmap. Checking volume information. The volume Test was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Click Repair Disk. REPRODUCING PATH: 1. Prepare HFS+ (non-case sensitive) partition (for example, 5GB) under MacOS X. 2. Copy linux kernel source tree (for example, 3.7-rc6 version) on this partition under MacOS X. 3. Then switch to Linux and mount this prepared partition. 4. Execute `sudo rm -r` under prepared directory with linux kernel source tree. 5. Unmount and boot back into OS X. 6. Open up Disk Utility and verify partition. REPRODUCIBILITY: 100% FIX: It is added code of node clearing in hfs_bnode_put() method for the case when node has flag HFS_BNODE_DELETED.

* hfsplus: add osx.* prefix for handling namespace of Mac OS X extended attributesVyacheslav Dubeyko2013-02-271-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hfsplus: reworked support of extended attributes. Current mainline implementation of hfsplus file system driver treats as extended attributes only two fields (fdType and fdCreator) of user_info field in file description record (struct hfsplus_cat_file). It is possible to get or set only these two fields as extended attributes. But HFS+ treats as com.apple.FinderInfo extended attribute an union of user_info and finder_info fields as for file (struct hfsplus_cat_file) as for folder (struct hfsplus_cat_folder). Moreover, current mainline implementation of hfsplus file system driver doesn't support special metadata file - attributes tree. Mac OS X 10.4 and later support extended attributes by making use of the HFS+ filesystem Attributes file B*-tree feature which allows for named forks. Mac OS X supports only inline extended attributes, limiting their size to 3802 bytes. Any regular file may have a list of extended attributes. HFS+ supports an arbitrary number of named forks. Each attribute is denoted by a name and the associated data. The name is a null-terminated Unicode string. It is possible to list, to get, to set, and to remove extended attributes from files or directories. It exists some peculiarity during getting of extended attributes list by means of getfattr utility. The getfattr utility expects prefix "user." before any extended attribute's name. So, it ignores any names that don't contained such prefix. Such behavior of getfattr utility results in unexpected empty output of extended attributes list even in the case when file (or folder) contains extended attributes. It needs to use empty string as regular expression pattern for names matching (getfattr --match=""). For support of extended attributes in HFS+: 1. It was added necessary on-disk layout declarations related to Attributes tree into hfsplus_raw.h file. 2. It was added attributes.c file with implementation of functionality of manipulation by records in Attributes tree. 3. It was reworked hfsplus_listxattr, hfsplus_getxattr, hfsplus_setxattr functions in ioctl.c. Moreover, it was added hfsplus_removexattr method.

Ensure the character right before "tegra" isn't a-z (case-insensitive), to make sure the keyword doesn't match those. The only files that the keyword doesn't match are the NVEC driver.

| | | | | | | | | | | | | | | | | | | | | | | Allow K: entries in MAINTAINERS to match directly against filenames; either those extracted from patch +++ or --- lines, or those specified on the command-line using the -f option. This potentially allows fewer lines in a MAINTAINERS entry, if all the relevant files are scattered throughout the whole kernel tree, yet contain some common keyword. An example would be using an ARM SoC name as the keyword to catch all related drivers. I don't think setting exact_pattern_match_hash would be appropriate here; at least for intended Tegra use case, this feature is to ensure that all Tegra-related driver changes get Cc'd to the Tegra mailing list. Setting exact_pattern_match_hash would prevent git history parsing for e.g. S-o-b tags, which still seems like it would be useful. Hence, this flag isn't set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ocfs2_block_group_alloc_discontig() disables chain relink by setting ac->ac_allow_chain_relink = 0 because it grabs clusters from multiple cluster groups. It doesn't keep the credits for all chain relink,but ocfs2_claim_suballoc_bits overrides this in this call trace: ocfs2_block_group_claim_bits()->ocfs2_claim_clusters()-> __ocfs2_claim_clusters()->ocfs2_claim_suballoc_bits() ocfs2_claim_suballoc_bits set ac->ac_allow_chain_relink = 1; then call ocfs2_search_chain() one time and disable it again, and then we run out of credits. Fix is to allow relink by default and disable it in ocfs2_block_group_alloc_discontig. Without this patch, End-users will run into a crash due to run out of credits, backtrace like this: RIP: 0010:[<ffffffffa0808b14>] [<ffffffffa0808b14>] jbd2_journal_dirty_metadata+0x164/0x170 [jbd2] RSP: 0018:ffff8801b919b5b8 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffff88022139ddc0 RCX: ffff880159f652d0 RDX: ffff880178aa3000 RSI: ffff880159f652d0 RDI: ffff880087f09bf8 RBP: ffff8801b919b5e8 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000001e00 R11: 00000000000150b0 R12: ffff880159f652d0 R13: ffff8801a0cae908 R14: ffff880087f09bf8 R15: ffff88018d177800 FS: 00007fc9b0b6b6e0(0000) GS:ffff88022fd40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 000000000040819c CR3: 0000000184017000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process dd (pid: 9945, threadinfo ffff8801b919a000, task ffff880149a264c0) Call Trace: ocfs2_journal_dirty+0x2f/0x70 [ocfs2] ocfs2_relink_block_group+0x111/0x480 [ocfs2] ocfs2_search_chain+0x455/0x9a0 [ocfs2] ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ef5da59f1260 ("scripts/kernel-doc: handle struct member __aligned") permits "char something [123] __aligned(8);". However, by using \d we constraint ourselves with integers. This is not always the case. In fact, it might be better to do char something[123] __aligned(sizeof(u16)); For example, With wireless_dev defining: u8 address[ETH_ALEN] __aligned(sizeof(u16)); With \d, scripts/kernel-doc erroneously says: Warning(include/net/cfg80211.h:2618): Excess struct/union/enum/typedef member 'address' description in 'wireless_dev' This is because the regex __aligned\s*\(\d+\) fails match at \d as sizeof is used. So replace \d with . to indicate "something" in kernel-doc to ignore __aligned(SOMETHING) in structs. With this change, we can use integers OR sizeof() or macros as we please.

* sysrq: don't depend on weak undefined arrays to have an address that ↵Linus Torvalds2013-02-271-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | compares as NULL When taking an address of an extern array, gcc quite naturally should be able to say "an address of an object can never be NULL" and just optimize away the test entirely. However, the new alternate sysrq reset code (commit 154b7a489a5b: "Input: sysrq - allow specifying alternate reset sequence") did exactly that, and declared platform_sysrq_reset_seq[] as a weak array, and expecting that testing the address of the array would show whether it actually got linked against something or not. And that doesn't work with all gcc versions. Clearly it works with *some* versions of gcc, and maybe it's even supposed to work, but it really is a very fragile concept. So instead of testing the address of the weak variable, just create a weak instance of that array that is empty. If some platform then has a real platform_sysrq_reset_seq[] that overrides our weak one, the linker will switch to that one, and it all works without any run-time conditionals at all.

* mm: do not grow the stack vma just because of an overrun on preceding vmaLinus Torvalds2013-02-271-0/+27
| | | | | | | | | | | | | | | | | | | | The stack vma is designed to grow automatically (marked with VM_GROWSUP or VM_GROWSDOWN depending on architecture) when an access is made beyond the existing boundary. However, particularly if you have not limited your stack at all ("ulimit -s unlimited"), this can cause the stack to grow even if the access was really just one past *another* segment. And that's wrong, especially since we first grow the segment, but then immediately later enforce the stack guard page on the last page of the segment. So _despite_ first growing the stack segment as a result of the access, the kernel will then make the access cause a SIGSEGV anyway! So do the same logic as the guard page check does, and consider an access to within one page of the next segment to be a bad access, rather than growing the stack to abut the next segment.
