TEXTSEARCH: Do not allow zero length patterns in the textsearch infrastructure

2007-12-14T18:31:59Z

[TEXTSEARCH]: Do not allow zero length patterns in the textsearch infrastructure [ Upstream commit: e03ba84adb62fbc6049325a5bc00ef6932fa5e39 ] If a zero length pattern is passed then return EINVAL. Avoids infinite loops (bm) or invalid memory accesses (kmp). Signed-off-by: Pablo Neira Ayuso Signed-off-by: Patrick McHardy Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

libcrc32c: keep intermediate crc state in cpu order

2007-12-14T18:31:56Z

It's upstream changeset ef19454bd437b2ba14c9cda1de85debd9f383484. [LIB] crc32c: Keep intermediate crc state in cpu order crypto/crc32.c:chksum_final() is computing the digest as *(__le32 *)out = ~cpu_to_le32(mctx->crc); so the low-level crc32c_le routines should just keep the crc in cpu order, otherwise it is getting swabbed one too many times on big-endian machines.

hexdump: more output formatting

2007-06-09T00:23:34Z

Add a prefix string parameter. Callers are responsible for any string length/alignment that they want to see in the output. I.e., callers should pad strings to achieve alignment if they want that. Add rowsize parameter. This is the number of raw data bytes to be printed per line. Must be 16 or 32. Add a groupsize parameter. This allows callers to dump values as 1-byte, 2-byte, 4-byte, or 8-byte numbers. Default is 1-byte numbers. If the total length is not an even multiple of groupsize, 1-byte numbers are printed. Add an "ascii" output parameter. This causes ASCII data output following the hex data output. Clean up some doc examples. Align the ASCII output on all lines that are produced by one call. Add a new interface, print_hex_dump_bytes(), that is a shortcut to print_hex_dump(), using default parameter values to print 16 bytes in byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.

timer stats: speedups

2007-06-01T15:18:30Z

Make timer-stats have almost zero overhead when enabled in the config but not used. (this way distros can enable it more easily) Also update the documentation about overhead of timer_stats - it was written for the first version which had a global lock and a linear list walk based lookup ;-) Signed-off-by: Ingo Molnar Cc: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

prohibit rcutorture from being compiled into the kernel

2007-05-24T03:14:12Z

There have been a number of instances where people have accidentally compiled rcutorture into the kernel (CONFIG_RCU_TORTURE_TEST=y), which has never been useful, and has often resulted in great frustration. The attached patch prohibits rcutorture from being compiled into the kernel. It may be excluded altogether or compiled as a module. People wishing to have rcutorture hammer their machine immediately upon boot are free to hand-edit lib/Kconfig.debug to remove the "depends on m" line. Thanks to Randy Dunlap for the trick that makes this work. Signed-off-by: Paul E. McKenney Acked-by: Josh Triplett Cc: "Randy.Dunlap" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Detach sched.h from mm.h

2007-05-21T16:18:19Z

First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.
