      perf tools: Fix error handling of unknown events · 777d1d71
      由 Stephane Eranian 提交于 
      There was a problem with the parse_events() code not printing the
correct event name when an event was unknown and starting with an 'r'.
The source of the problem was the way raw notation was parsed.

Without the patch:
	$ perf stat -e retired_foo
	invalid event modifier: 'tired_foo'

With the patch:
	$ perf stat -e retired_foo
	invalid or unsupported event: 'retired_foo'

This also covers the case where the name of the event was not printed at
all when perf was linked with libpfm4.

      perf evlist: Fix missing event name init for default event · cc2d86b0
      由 Stephane Eranian 提交于 
      When no event is given to perf record, perf top, a default event is
initialized (cycles). However, perf_evlist__add_default() was not
setting the symbolic name for the event. Perf top worked simply because
it was reconstructing the name from the event code. But it should not
have to do this. This patch initializes the evsel->name field properly.

This second version improves the code flow on the non error path.

      perf list: Fix exit value · 77e57297
      由 Stephane Eranian 提交于 
      This patch fixes an issue with the exit value of perf list:

$ perf list; echo $?
129

perf list returns an error exit code even though there is no error.

There was a stray exit(129) in print_events(). This patch removes this
exit().

$ perf list; echo $?

      perf probe: Filter out redundant inline-instances · 3f4460a2
      由 Masami Hiramatsu 提交于 
      With gcc4.6, some instances of concrete inlined function looks redundant
and broken, because it appears inside of a concrete instance and its
call_file and call_line are same as the original abstruct's decl_file
and decl_line respectively.

e.g.
 [  d1aa]    subprogram
             external             (flag) Yes
             name                 (strp) "add_timer"
             decl_file            (data1) 2		;here is original
             decl_line            (data2) 847		;line and file
             prototyped           (flag) Yes
             inline               (data1) inlined (1)
             sibling              (ref4) [  d1c6]
...
 [ 11d84]    subprogram
             abstract_origin      (ref4) [  d1aa]	; concrete instance
             low_pc               (addr) .text+0x000000000000246f <add_timer>
             high_pc              (addr) .text+0x000000000000248b <mod_timer_pending>
             frame_base           (block1)               [   0] call_frame_cfa
             sibling              (ref4) [ 11dd9]
 [ 11d9f]      formal_parameter
               abstract_origin      (ref4) [  d1b9]
               location             (data4) location list [  701b]
 [ 11da8]      inlined_subroutine
               abstract_origin      (ref4) [  d1aa]	; redundant instance
               low_pc               (addr) .text+0x000000000000247e <add_timer+0xf>
               high_pc              (addr) .text+0x0000000000002480 <add_timer+0x11>
               call_file            (data1) 2		; call line and file
               call_line            (data2) 847		; are same as above

Those redundant instances leads unwilling results;

e.g. find probe points inside of functions even if we specify
a function entry as below;

$ perf probe -V add_timer
Available variables at add_timer
        @<add_timer+0>
                struct timer_list*      timer
        @<add_timer+15>
                (No matched variables)

So, this filters out those redundant instances based on call-site and
decl-site information.

      perf probe: Search concrete out-of-line instances · db0d2c64
      由 Masami Hiramatsu 提交于 
      gcc 4.6 generates a concrete out-of-line instance when there is a
function which is implicitly inlined somewhere but also has its own
instance. The concrete out-of-line instance means that it has an
abstract origin of the function which is referred by not only
inlined-subroutines but also a concrete subprogram.

Since current dwarf_func_inline_instances() can find only instances of
inlined-subroutines, this introduces new die_walk_instances() to find
both of subprogram and inlined-subroutines.

e.g. without this,
Available variables at sched_group_rt_period
        @<cpu_rt_period_read_uint+9>
                struct task_group*      tg

perf probe failed to find actual subprogram instance of
sched_group_rt_period().

With this,

Available variables at sched_group_rt_period
        @<cpu_rt_period_read_uint+9>
                struct task_group*      tg
        @<sched_group_rt_period+0>
                struct task_group*      tg

Now it found the sched_group_rt_period() itself.

      perf probe: Avoid searching variables in intermediate scopes · f182e3e1
      由 Masami Hiramatsu 提交于 
      Fix variable searching logic to search one in inner than local scope or
global(CU) scope. In the other words, skip searching in intermediate
scopes.

e.g., in the following code,

int var1;

void inline infunc(int i)
{
    i++;   <--- [A]
}

void func(void)
{
   int var1, var2;
   infunc(var2);
}

At [A], "var1" should point the global variable "var1", however, if user
mis-typed as "var2", variable search should be failed. However, current
logic searches variable infunc() scope, global scope, and then func()
scope. Thus, it can find "var2" variable in func() scope. This may not
be what user expects.

So, it would better not search outer scopes except outermost (compile
unit) scope which contains only global variables, when it failed to find
given variable in local scope.

E.g.

Without this:
$ perf probe -V pre_schedule --externs > without.vars

With this:
$ perf probe -V pre_schedule --externs > with.vars

Check the diff:
$ diff without.vars with.vars
88d87
<               int     cpu
133d131
<               long unsigned int*      switch_count

These vars are actually in the scope of schedule(), the caller of
pre_schedule().

      perf probe: Fix to search local variables in appropriate scope · 221d0611
      由 Masami Hiramatsu 提交于 
      Fix perf probe to search local variables in appropriate local inlined
function scope. For example, pre_schedule() has only 2 local variables,
as below;

$ perf probe -L pre_schedule
<pre_schedule@/home/mhiramat/ksrc/linux-2.6/kernel/sched.c:0>
      0  static inline void pre_schedule(struct rq *rq, struct task_struct *prev)
         {
      2         if (prev->sched_class->pre_schedule)
      3                 prev->sched_class->pre_schedule(rq, prev);
         }

However, current perf probe shows 4 local variables on pre_schedule(),
because it searches variables in the caller(schedule()) scope.

$ perf probe -V pre_schedule
Available variables at pre_schedule
        @<schedule+445>
                int     cpu
                long unsigned int*      switch_count
                struct rq*      rq
                struct task_struct*     prev

This patch fixes this issue by searching variables in the local scope of
the instance of inlined function. Here is the result.

$ perf probe -V pre_schedule
Available variables at pre_schedule
        @<schedule+445>
                struct rq*      rq
                struct task_struct*     prev

      perf probe: Fix to search nested inlined functions in CU · b0e9cb28
      由 Masami Hiramatsu 提交于 
      Fix perf probe to walk through the lines of all nested inlined function
call sites and declared lines when a whole CU is passed to the line
walker.

The die_walk_lines() can have two different type of DIEs, subprogram (or
inlined-subroutine) DIE and CU DIE.

If a caller passes a subprogram DIE, this means that the walker walk on
lines of given subprogram. In this case, it just needs to search on
direct children of DIE tree for finding call-site information of inlined
function which directly called from given subprogram.

On the other hand, if a caller passes a CU DIE to the walker, this means
that the walker have to walk on all lines in the source files included
in given CU DIE. In this case, it has to search whole DIE trees of all
subprograms to find the call-site information of all nested inlined
functions.

Without this patch:

$ perf probe --line kernel/cpu.c:151-157
</home/mhiramat/ksrc/linux-2.6/kernel/cpu.c:151>

         static int cpu_notify(unsigned long val, void *v)
         {
    154         return __cpu_notify(val, v, -1, NULL);
         }

With this:
$ perf probe --line kernel/cpu.c:151-157
</home/mhiramat/ksrc/linux-2.6/kernel/cpu.c:151>

    152  static int cpu_notify(unsigned long val, void *v)
         {
    154         return __cpu_notify(val, v, -1, NULL);
         }

As you can see, --line option with source line range shows the declared
lines as probe-able.

      pnfs: Automatically select blocks & objects layouts · 8cf1fb21
      由 Boaz Harrosh 提交于 
      Just like files-layout, blocks & objects layouts are part of the
NFS 4.1 protocol and should be automatically selected if NFS_4_1
is selected. The small problem is that these depend on other
Kernel support being present, while files only depends on NFS
itself.

This patch removes from the user choice the presence of objects
and blocks layout. But makes sure these are selected only if
the depended subsystems are present in the Kernel.

      ext4: Properly count journal credits for long symlinks · 8c208719
      由 Eric Sandeen 提交于 
      Commit df5e6223 ("ext4: fix deadlock in ext4_symlink() in ENOSPC
conditions") recalculated the number of credits needed for a long
symlink, in the process of splitting it into two transactions.  However,
the first credit calculation under-counted because if selinux is
enabled, credits are needed to create the selinux xattr as well.

Overrunning the reservation will result in an OOPS in
jbd2_journal_dirty_metadata() due to this assert:

  J_ASSERT_JH(jh, handle->h_buffer_credits > 0);

Fix this by increasing the reservation size.

      move RLIMIT_NPROC check from set_user() to do_execve_common() · 72fa5997
      由 Vasiliy Kulikov 提交于 
      The patch http://lkml.org/lkml/2003/7/13/226 introduced an RLIMIT_NPROC
check in set_user() to check for NPROC exceeding via setuid() and
similar functions.

Before the check there was a possibility to greatly exceed the allowed
number of processes by an unprivileged user if the program relied on
rlimit only.  But the check created new security threat: many poorly
written programs simply don't check setuid() return code and believe it
cannot fail if executed with root privileges.  So, the check is removed
in this patch because of too often privilege escalations related to
buggy programs.

The NPROC can still be enforced in the common code flow of daemons
spawning user processes.  Most of daemons do fork()+setuid()+execve().
The check introduced in execve() (1) enforces the same limit as in
setuid() and (2) doesn't create similar security issues.

Neil Brown suggested to track what specific process has exceeded the
limit by setting PF_NPROC_EXCEEDED process flag.  With the change only
this process would fail on execve(), and other processes' execve()
behaviour is not changed.

Solar Designer suggested to re-check whether NPROC limit is still
exceeded at the moment of execve().  If the process was sleeping for
days between set*uid() and execve(), and the NPROC counter step down
under the limit, the defered execve() failure because NPROC limit was
exceeded days ago would be unexpected.  If the limit is not exceeded
anymore, we clear the flag on successful calls to execve() and fork().

The flag is also cleared on successful calls to set_user() as the limit
was exceeded for the previous user, not the current one.

Similar check was introduced in -ow patches (without the process flag).

v3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().
