2006-06-20[PATCH] audit: path-based rulesAmy Griffis1-1/+2
In this implementation, audit registers inotify watches on the parent directories of paths specified in audit rules. When audit's inotify event handler is called, it updates any affected rules based on the filesystem event. If the parent directory is renamed, removed, or its filesystem is unmounted, audit removes all rules referencing that inotify watch. To keep things simple, this implementation limits location-based auditing to the directory entries in an existing directory. Given a path-based rule for /foo/bar/passwd, the following table applies: passwd modified -- audit event logged passwd replaced -- audit event logged, rules list updated bar renamed -- rule removed foo renamed -- untracked, meaning that the rule now applies to the new location Audit users typically want to have many rules referencing filesystem objects, which can significantly impact filtering performance. This patch also adds an inode-number-based rule hash to mitigate this situation. The patch is relative to the audit git tree: http://kernel.org/git/?p=linux/kernel/git/viro/audit-current.git;a=summary and uses the inotify kernel API: http://lkml.org/lkml/2006/6/1/145 Signed-off-by: Amy Griffis <amy.griffis@hp.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2006-05-15[PATCH] root mount failure: emit filesystems attemptedAndy Whitcroft1-0/+5
When we fail to mount from a valid root device list out the filesystems we have tried to mount it with. This gives the user vital diagnostics as to what is missing from their kernel. For example in the fragment below the kernel does not have CRAMFS compiled into the kernel and yet appears to recognise it at the RAMDISK detect stage. Later the mount fails as we don't have the filesystem. RAMDISK: cramfs filesystem found at block 0 RAMDISK: Loading 1604KiB [1 disk] into ram disk... done. XFS: bad magic number XFS: SB validate failed No filesystem could mount root, tried: reiserfs ext3 ext2 msdos vfat iso9660 jfs xfs Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1) Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Copy the filenames of hardlinks when inserting them into the hash, since the "name" pointer may point to scratch space (name_buf). Not doing so results in corruption if the scratch space is later overwritten: the wrong file may be hardlinked, or, if the scratch space contains garbage, the link will fail and a 0-byte file will be created instead.

2006-03-26[PATCH] remove fixup_cpu_present_map()Andrew Morton1-19/+0
Since the addition of boot_cpu_init(), fixup_cpu_present_map() has been a no-op. That's because fixup_cpu_present_map() won't touch cpu_present_map if it has any bits set, and boot_cpu_init() sets a bit. So remove fixup_cpu_present_map(). A consequence of this (actually of the boot_cpu_init() change) is that the architecture _must_ populate cpu_present_map itself (probably in smp_prepare_cpus()). fixup_cpu_present_map() won't do it any more. If the architecture doesn't do this, it'll only bring up a single CPU. The other side effect (though less serious) is that smp_prepare_boot_cpu() no longer needs to mark the boot cpu in the online and present maps - boot_cpu_init() does that for everyone (to make early printks work).

2006-03-25[PATCH] BLK_DEV_INITRD: do not require BLK_DEV_RAM=yZdenek Pavlas1-0/+10
Initramfs initrd images do not need a ramdisk device, so remove this restriction in Kconfig. BLK_DEV_RAM=n saves about 13k on i386. Also without ramdisk device there's no need for "dry run", so initramfs unpacks much faster. People using cramfs, squashfs, or gzipped ext2/minix initrd images are probably smart enough not to turn off ramdisk support by accident.

2006-03-25[PATCH] initcall failure reportingAndrew Morton1-7/+15
We presently ignore the return values from initcalls. But that can carry useful debugging information. So print it out if it's non-zero. It turns out the -ENODEV happens quite a lot, due to built-in drivers which have no hardware to drive. So suppress that unless initcall_debug was specified. Also make the warning message more friendly by printing the name of the initcall function. Also drop the KERN_DEBUG from the initcall_debug message. If we specified inticall_debug then we obviously want to see the messages.

2006-03-24[PATCH] vfs: MS_VERBOSE should be MS_SILENTTheodore Ts'o1-1/+1
The meaning of MS_VERBOSE is backwards; if the bit is set, it really means, "don't be verbose". This is confusing and counter-intuitive. In addition, there is also no way to set the MS_VERBOSE flag in the mount(8) program in util-linux, but interesting, it does define options which would do the right thing if MS_SILENT were defined, which unfortunately we do not: #ifdef MS_SILENT { "quiet", 0, 0, MS_SILENT }, /* be quiet */ { "loud", 0, 1, MS_SILENT }, /* print out messages. */ #endif So the obvious fix is to deprecate the use of MS_VERBOSE and replace it with MS_SILENT.

2006-03-23[PATCH] __GENERIC_PER_CPU changesEric Dumazet1-6/+2
Now CONFIG_DEBUG_INITDATA is in, initial percpu data [__per_cpu_start,__per_cpu_end] can be declared as a redzone, and invalid accesses after boot can be detected, at least for i386. We can let non possible cpus percpu data point to this 'redzone' instead of NULL . NULL was not a good choice because part of [0..32768] memory may be readable and invalid accesses may happen unnoticed. If CONFIG_DEBUG_INITDATA is not defined, each non possible cpu points to the initial percpu data (__per_cpu_offset[cpu] == 0), thus invalid accesses wont be detected/crash. This patch also moves __per_cpu_offset[] to read_mostly area to avoid false sharing.

2006-03-23[PATCH] swsusp: userland interfaceRafael J. Wysocki1-0/+1
This patch introduces a user space interface for swsusp. The interface is based on a special character device, called the snapshot device, that allows user space processes to perform suspend and resume-related operations with the help of some ioctls and the read()/write() functions.  Additionally it allows these processes to allocate free swap pages from a selected swap partition, called the resume partition, so that they know which sectors of the resume partition are available to them. The interface uses the same low-level system memory snapshot-handling functions that are used by the built-it swap-writing/reading code of swsusp. The interface documentation is included in the patch. The patch assumes that the major and minor numbers of the snapshot device will be 10 (ie. misc device) and 231, the registration of which has already been requested. Signed-off-by: Rafael J.

2006-02-10[PATCH] kexec: fix in free initrd when overlapped with crashkernel regionHaren Myneni1-1/+23
It is possible that the reserved crashkernel region can be overlapped with initrd since the bootloader sets the initrd location. When the initrd region is freed, the second kernel memory will not be contiguous. The Kexec_load can cause an oops since there is no contiguous memory to write the second kernel or this memory could be used in the first kernel itself and may not be part of the dump. For example, on powerpc, the initrd is located at 36MB and the crashkernel starts at 32MB. The kexec_load caused panic since writing into non-allocated memory (after 36MB). We could see the similar issue even on other archs. One possibility is to move the initrd outside of crashkernel region. But, the initrd region will be freed anyway before the system is up. This patch fixes this issue and frees only regions that are not part of crashkernel memory in case overlaps. Signed-off-by: Haren Myneni <haren@us.ibm.com> Acked-by: "Eric W.

There was a check for a NULL cpuset pointer in the routine cpuset_update_task_memory_state() that was only needed during system boot, after the memory subsystem was initialized, before the cpuset subsystem was initialized, to catch a NULL task->cpuset pointer. Add a cpuset_init_early() routine, just before the mem_init() call in init/main.c, that sets up just enough of the init tasks cpuset structure to render cpuset_update_task_memory_state() calls harmless.

2006-01-09[PATCH] slob: introduce the SLOB allocatorMatt Mackall1-0/+13
configurable replacement for slab allocator This adds a CONFIG_SLAB option under CONFIG_EMBEDDED. When CONFIG_SLAB is disabled, the kernel falls back to using the 'SLOB' allocator. SLOB is a traditional K&R/UNIX allocator with a SLAB emulation layer, similar to the original Linux kmalloc allocator that SLAB replaced. It's signicantly smaller code and is more memory efficient. But like all similar allocators, it scales poorly and suffers from fragmentation more than SLAB, so it's only appropriate for small systems. It's been tested extensively in the Linux-tiny tree. I've also stress-tested it with make -j 8 compiles on a 3G SMP+PREEMPT box (not recommended). Here's a comparison for otherwise identical builds, showing SLOB saving nearly half a megabyte of RAM: $ size vmlinux* text data bss dec hex filename 3336372 529360 190812 4056544 3de5e0 vmlinux-slab 3323208 527948 190684 4041840 3dac70 vmlinux-slob $ size mm/{slab,slob}.o text data bss dec hex filename 13221 752 48 14021 36c5 mm/slab.o 1896 52 8 1956 7a4 mm/slob.o /proc/meminfo: SLAB SLOB delta MemTotal: 27964 kB 27980 kB +16 kB MemFree: 24596 kB 25092 kB +496 kB Buffers: 36 kB 36 kB 0 kB Cached: 1188 kB 1188 kB 0 kB SwapCached: 0 kB 0 kB 0 kB Active: 608 kB 600 kB -8 kB Inactive: 808 kB 812 kB +4 kB HighTotal: 0 kB 0 kB 0 kB HighFree: 0 kB 0 kB 0 kB LowTotal: 27964 kB 27980 kB +16 kB LowFree: 24596 kB 25092 kB +496 kB SwapTotal: 0 kB 0 kB 0 kB SwapFree: 0 kB 0 kB 0 kB Dirty: 4 kB 12 kB +8 kB Writeback: 0 kB 0 kB 0 kB Mapped: 560 kB 556 kB -4 kB Slab: 1756 kB 0 kB -1756 kB CommitLimit: 13980 kB 13988 kB +8 kB Committed_AS: 4208 kB 4208 kB 0 kB PageTables: 28 kB 28 kB 0 kB VmallocTotal: 1007312 kB 1007312 kB 0 kB VmallocUsed: 48 kB 48 kB 0 kB VmallocChunk: 1007264 kB 1007264 kB 0 kB (this work has been sponsored in part by CELF) From: Ingo Molnar <mingo@elte.hu> Fix 32-bitness bugs in mm/slob.c.

2006-01-06[PATCH] md: remove personality numbering from mdNeilBrown1-13/+9
md supports multiple different RAID level, each being implemented by a 'personality' (which is often in a separate module). These personalities have fairly artificial 'numbers'. The numbers are use to: 1- provide an index into an array where the various personalities are recorded 2- identify the module (via an alias) which implements are particular personality. Neither of these uses really justify the existence of personality numbers. The array can be replaced by a linked list which is searched (array lookup only happens very rarely). Module identification can be done using an alias based on level rather than 'personality' number. The current 'raid5' modules support two level (4 and 5) but only one personality. This slight awkwardness (which was handled in the mapping from level to personality) can be better handled by allowing raid5 to register 2 personalities. With this change in place, the core md module does not need to have an exhaustive list of all possible personalities, so other personalities can be added independently. This patch also moves the check for chunksize being non-zero into the ->run routines for the personalities that need it, rather than having it in core-md. This has a side effect of allowing 'faulty' and 'linear' not to have a chunk-size set.

2006-01-06[PATCH] NOMMU: Make SYSV IPC SHM use ramfs facilities on NOMMUDavid Howells1-1/+0
The attached patch makes the SYSV IPC shared memory facilities use the new ramfs facilities on a no-MMU kernel. The following changes are made: (1) There are now shmem_mmap() and shmem_get_unmapped_area() functions to allow the IPC SHM facilities to commune with the tiny-shmem and shmem code. (2) ramfs files now need resizing using do_truncate() rather than by modifying the inode size directly (see shmem_file_setup()). This causes ramfs to attempt to bind a block of pages of sufficient size to the inode. (3) CONFIG_SYSVIPC is no longer contingent on CONFIG_MMU.
