This allows a hyphenated range of positive numbers in the string passed to command line helper function, get_options. Currently the command line option "isolcpus=" takes as its argument a list of cpus. Format: <cpu number>,...,<cpu number> Valid values of <cpu_number> include all cpus, 0 to "number of CPUs in system - 1". This can get extremely long when isolating the majority of cpus on a large system. The kernel isolcpus code would not need any changing to use this feature. To use it, the change would be in the command line format for 'isolcpus=' Format: <cpu number>,...,<cpu number> or <cpu number>-<cpu number> (must be a positive range in ascending order.) or a mixture <cpu number>,...,<cpu number>-<cpu number> Signed-off-by: NDerek Fults <dfults@sgi.com> Cc: "Randy.Dunlap" <rdunlap@xenotime.net> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Clean up several code points in which the return code from misc_register is not handled properly. Several modules failed to deregister various hooks when misc_register fails, and this patch cleans them up. Also there are a few modules that legitimately don't care about the failure status of misc register. These drivers however unilaterally call misc_deregister on module unload. Since misc_register doesn't initialize the list_head in the init_routine if it fails, the deregister operation is at risk for oopsing when list_del is called. The initial solution was to manually init the list in the miscdev structure in each of those modules, but the consensus in this thread was to consolodate and do that universally inside misc_register.

This is on our "Envoy" boxes which we have, according to the documentation, an "Exar ST16C554/554D Quad UART with 16-byte Fifo's". The box also has two other "on-board" serial ports and a modem chip. The two on-board serial UARTs were being detected along with the first two Exar UARTs. The last two Exar UARTs were not showing up and neither was the modem. This patch was the only way I could the kernel to see beyond the standard four serial ports and get all four of the Exar UARTs to show up.

One of the mistakes a module_param() user can make is to supply default value of module parameter as the last argument. module_param() accepts permissions instead. If default value is, say, 3 (-------wx), parameter becomes world-writeable. So far, the only remedy was to apply grep(1) and read drivers submitted to -mm. BTDT. With this patch applied, compiler will finally do some job. *) bounds checking on permissions *) world-writeable bit checking on permissions *) compile breakage if checks trigger First version of this check (only "& 2" part) directly caught 4 out of 7 places during my last grep.

Currently taskstats_user_cmd()/taskstats_exit() do: 1) allocate stats 2) fill stats 3) make a temporary copy on stack (236 bytes) 4) copy that copy to skb 5) free stats With the help of nla_reserve() we can operate on skb->data directly, thus avoiding all these steps except 2). So, before this patch: // copy *stats to skb->data int mk_reply(skb, ..., struct taskstats *stats); fill_pid(stats); mk_reply(skb, ..., stats); After: // return a pointer to skb->data struct taskstats *mk_reply(skb, ...); stat = mk_reply(skb, ...); fill_pid(stats); Shrinks taskatsks.o by 162 bytes. A stupid benchmark (send one million TASKSTATS_CMD_ATTR_PID) shows the real user sys before: 4.02 0.06 3.96 4.02 0.04 3.98 4.02 0.04 3.97 after: 3.86 0.08 3.78 3.88 0.10 3.77 3.89 0.09 3.80 but this looks suspiciously good.

If there are no listeners, every task does unneeded kmem_cache alloc/free on exit. We don't need listeners->sem for 'if (!list_empty())' check.

由 Roland McGrath 提交于
The CLONE_CHILD_CLEARTID flag is used by NPTL to have its threads communicate via memory/futex when they exit, so pthread_join can synchronize using a simple futex wait. The word of user memory where NPTL stores a thread's own TID is what it passes; this gets reset to zero at thread exit. It is not desireable to touch this user memory when threads are dying due to a fatal signal. A core dump is more usefully representative of the dying program state if the threads live at the time of the crash have their NPTL data structures unperturbed. The userland expectation of CLONE_CHILD_CLEARTID has only ever been that it works for a thread making an _exit system call. This problem was identified by Ernie Petrides <petrides@redhat.com>.

I've been using Steve Grubb's purely evil "fsfuzzer" tool, at http://people.redhat.com/sgrubb/files/fsfuzzer-0.4.tar.gz Basically it makes a filesystem, splats some random bits over it, then tries to mount it and do some simple filesystem actions. At best, the filesystem catches the corruption gracefully. At worst, things spin out of control. As you might guess, we found a couple places in ext4 where things spin out of control :) First, we had a corrupted directory that was never checked for consistency... it was corrupt, and pointed to another bad "entry" of length 0. The for() loop looped forever, since the length of ext4_next_entry(de) was 0, and we kept looking at the same pointer over and over and over and over... I modeled this check and subsequent action on what is done for other directory types in ext4_readdir... (adding this check adds some computational expense; I am testing a followup patch to reduce the number of times we check and re-check these directory entries, in all cases. Thanks for the idea, Andreas). Next we had a root directory inode which had a corrupted size, claimed to be > 200M on a 4M filesystem. There was only really 1 block in the directory, but because the size was so large, readdir kept coming back for more, spewing thousands of printk's along the way. Per Andreas' suggestion, if we're in this read error condition and we're trying to read an offset which is greater than i_blocks worth of bytes, stop trying, and break out of the loop. With these two changes fsfuzz test survives quite well on ext4.
