[PATCH] tools/liblockdep: Fix linker error in case of cross compile.

[Eunbong Song]

If we try to cross compile liblockdep, even if we set the CROSS_COMPILE variable
the linker error can occur because LD is not set with CROSS_COMPILE.
This patch adds "LD" can be set automatically with CROSS_COMPILE variable so
fixes linker error problem.

[PATCH] tools/liblockdep: change current_obj from thread-local storage to non thread-local storage

[Eunbong Song]

current_obj is declared as a thread-local storage.
This prevent to detect locking  problem between multiple threads because
each thread has it's own current_obj. liblockdep can only detect locking 
problem in a single
thread. However, pthread_mutex_xxx, pthread_rwlock_xxx functions are mainly 
used for synchro
nization of data between multiple threads.
This patch changes current_obj to non thread-local storage. and current_obj.pid 
is getting
from getpid system call.

[PATCH] staging: octeon-ethernet: disable load balance for receiving packet when CONFIG_RPS is enabled.

[Eunbong Song]

It's better disable load balance for receiving packet when CONFIG_RPS is 
enabled.
If not, octeon-ethernet driver select CPU and then the rps select again CPU.
It can be ipi interrupts overhead and packet reordering could be possible.

[PATCH resend] mips: add arch_trigger_all_cpu_backtrace() function

[Eunbong Song]

Currently, arch_trigger_all_cpu_backtrace() is defined in only x86 and sparc 
which has nmi interrupt.
But in case of softlockup not a hadrlockup, it could be possible to dump 
backtrace of all cpus.
And this could be helpful for debugging.

for example, if system has 2 cpus.

CPU 0   CPU 1
 acquire read_lock()

try to do write_lock()

 ,,,
 missing read_unlock()

In this case, dump_stack() print only backtrace for "CPU 0".
If CPU1's calltrace is printed it's very helpful.

This patch adds arch_trigger_all_cpu_backtrace() for mips architecture.
And this enables when softlockup_all_cpu_backtrace is equalt to 1 and
softlock is occurred to dump all cpu's backtrace.

Currently, in case of mips there is no case include_self is true, so this is 
not a problem. 
arch_trigger_all_cpu_backtrace can only be called from 
trigger_allbutself_cpu_backtrace() in kernel/watchdog.c.
But as you said, if the case will be added, we should consider that.

Thanks.

Hi John.
Actually, I just follow the same function of sparc architecture.
You can find this in arch/sparc/include/asm/irq_64.h as below

void arch_trigger_all_cpu_backtrace(bool);
#define arch_trigger_all_cpu_backtrace arch_trigger_all_cpu_backtrace

I guess this is used for conditional compile. 
See below.
include/linux/nmi.h
#ifdef arch_trigger_all_cpu_backtrace
static inline bool trigger_all_cpu_backtrace(void)
{
arch_trigger_all_cpu_backtrace(true);

return true;
}
static inline bool trigger_allbutself_cpu_backtrace(void)
{
arch_trigger_all_cpu_backtrace(false);
return true;
}
#else
static inline bool trigger_all_cpu_backtrace(void)
{
return false;
}
static inline bool trigger_allbutself_cpu_backtrace(void)
{
return false;
}
#endif

Thanks.

I can't understand this. Please, could you explain this more ?
My patch just replaces put_unaligned with put_unaligned_le16. and this just 
write compression data
in little endian byte-order  regardless of machine byte-order, like ext file 
system. 
So, i guess there is no  problem what you pointed

Re: RE: [PATCH] lib : lz4 using put_unaligned_le16 instead of put_unaligned

[Eunbong Song]

  If your patch is applied, the data which is compressed
 by your big-endian system won't be decompressed in other little-endian system.

I can't understand this. Please, could you explain this more ?
My patch just replaces put_unaligned with put_unaligned_le16. and this just 
write compression data
in little endian byte-order  regardless of machine byte-order, like ext file 
system. 
So, i guess there is no  problem what you pointed 

Thanks.

> So it's never worked?
Yes, it's always failed to mount. 
> Did you test on a little endian machine after making this change?
Unfortunately, i don't have little endian machine. So i couldn't test that.

Additionaly, when lz4 compress calls lz4_compressctx() function and uses 
LZ4_WRITE_LITTLEENDIAN_16() macro.
And When lz4 decompress  calls lz4_uncompress_unknownoutputsize function and 
uses LZ4_READ_LITTLEENDIAN_16 macro.
There is endian mismatch in big endian machine as i metioned before. when 
compress lz4 write big endian bytes order
and when decompress lz4 reads little endian bytes order. 
So i means we should make there is no endian mismatch between compress and 
decompress operation.

Thanks.

Actually, i have tested zram with lz4 functions in my board(mips64 big endian). 
Everytime  i try to mount my ext4 zram image i have failed. 
After applying this patch, that problem was disappeared.

Thanks. 

[PATCH] lib : lz4 using put_unaligned_le16 instead of put_unaligned

[Eunbong Song]

In case of mips bigendian machine, put_unaligned writes bigendian bytes order. 
This is defined in arch/mips/include/asm/unaligned.h. So it's right use 
put_unaligned_le16 function instead of put_unaligned.
This patch also fixes problem fail to mount zram ext4 partition with "zram: 
Decompression failed! err=-1, page=0" in mips bigendian machine.

[PATCH] mtd: fsl_ifc_nand: Recover corrupted empty page for preventing read-only mount in UBIFS

[Eunbong Song]

Even if the meaning of EUCLEAN was changed by commit edbc4540.
There is still possibility of read-only mount in UBIFS with ubifs_scan() 
"corrupt empty space at LEB".
So i made this patch for fix that problem.
This patch do as follow.
 - If there are ecc errors which is equal to or less than chip->ecc.strength in 
page.
 - Check that page has how many zero bits, and if zero bits are equal to or 
less than
   chip->ecc.strength then overwrite 1 to zero bits in buf.

ubifs_scan() cannot detect corrupted empty space because buf is recovered by 
this patch.
And this is safe because ecc controller can correct up to chip->ecc.strength 
bits.

[PATCH] mtd: fsl_ifc_nand: Recover corrupted empty page for preventing read-only mount in UBIFS

[Eunbong Song]

Even if the meaning of EUCLEAN was changed by commit edbc4540.
There is still possibility of read-only mount in UBIFS with ubifs_scan() 
corrupt empty space at LEB.
So i made this patch for fix that problem.
This patch do as follow.
 - If there are ecc errors which is equal to or less than chip-ecc.strength in 
page.
 - Check that page has how many zero bits, and if zero bits are equal to or 
less than
   chip-ecc.strength then overwrite 1 to zero bits in buf.

ubifs_scan() cannot detect corrupted empty space because buf is recovered by 
this patch.
And this is safe because ecc controller can correct up to chip-ecc.strength 
bits.

[PATCH] mtd: nand: make more readable panic_nand_wait_ready() and nand_wait_ready()

[Eunbong Song]

panic_nand_wait_ready() and nand_wait_ready() calls dev_ready() without 
checking if it exists.
This patch add check routine dev_ready() before run dev_ready()
and this makes the code more readable

kbuild: warning with cavium_octeon_defconfig

[EUNBONG SONG]

Hello. 
Every time i config with arch/mips/configs/cavium_octeon_defconfig, the 
following warning messages are showed.
warning: (MIPS_SEAD3 && PMC_MSP && CPU_CAVIUM_OCTEON) selects 
USB_EHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && 
USB && USB_EHCI_HCD)
warning: (MIPS_SEAD3 && PMC_MSP && CPU_CAVIUM_OCTEON) selects

I guess it caused by commit id: 9296d94d83649e1c2f25c87dc4ead9c2ab073305 

Thanks.

Hi, Ted.
I appreciate for your fantastic explanation. It's really great and very helpful 
for me.
Now i can understand about this issue thanks to you.

Thanks!

Question about ext4 excessive stall time

[EUNBONG SONG]

Hello. 
I saw some commit messages about excessive stall times in ext4. 
The same problem was reproduced in my board. Actually, i'm not sure that is the 
same problem.
But the calltrace message is very similar with commit id: f783f091. 

My board configuration as follow.
Linux: 2.6.32.60
CPU: 8CPU
Disk: SSD
File system: ext4

I know my kernel version is so old. I just want to know why this problem is 
happened.
Because of my kernel version is old? or Because of disk ?,,
If anyone knows about this problem, Could you help me?

As i said,  the calltrace message is very similar with commit id: f783f091 as 
below.
Because i enabled hungtask detection and set the hungtask timeout to 120 
seconds. 
the calltrace messages were printed by this.

Question about ext4 excessive stall time

[EUNBONG SONG]

Hello. 
I saw some commit messages about excessive stall times in ext4. 
The same problem was reproduced in my board. Actually, i'm not sure that is the 
same problem.
But the calltrace message is very similar with commit id: f783f091. 

My board configuration as follow.
Linux: 2.6.32.60
CPU: 8CPU
Disk: SSD
File system: ext4

I know my kernel version is so old. I just want to know why this problem is 
happened.
Because of my kernel version is old? or Because of disk ?,,
If anyone knows about this problem, Could you help me?

As i said,  the calltrace message is very similar with commit id: f783f091 as 
below.
Because i enabled hungtask detection and set the hungtask timeout to 120 
seconds. 
the calltrace messages were printed by this.

 So what's happening is this.  The CFQ I/O scheduler prioritizes reads
 over writes, since most reads are synchronous (for example, if the
 compiler is waiting for the data block from include/unistd.h, it cant
 make forward progress until it receives the data blocks; there is an
 exception for readahead blocks, but those are dealt with at a low
 priority), and most writes are synchronous (since they are issued by
 the writeback daemons, and unless we are doing an fsync, no one is
 waiting for them).

 The problem comes when a metadata block, usually one which is shared
 across multiple files is undergoing writeback, such as an inode table
 block or a allocation bitmap block.  The write gets issued as a low
 priority I/O operation.  Then during the the next jbd2 transaction,
 some userspace operation needs to modify that metadata block, and in
 order to do that, it has to call jbd2_journal_get_write_access().  But
 if there is heavy read traffic going on, due to some other process
 using the disk a lot, the writeback operation may end up getting
 starved, and doesn't get acted on for a very long time.

 But the moment a process called jbd2_journal_get_write_access(), the
 write has effectively become one which is synchronous, in that forward
 progress of at least one process is now getting blocked waiting for
 this I/O to complete, since the buffer_head is locked for writeback,
 possibly for hundreds or thousands of milliseconds, and
 jbd2_journal_get_write_access() can not proceed until it can get the
 buffer_head lock.

 This was discussed at least month's Linux Storage, File System, and MM
 worksthop.  The right solution is to for lock_buffer() to notice if
 the buffer head has been locked for writeback, and if so, to bump the
 write request to the head of the elevator.  Jeff Moyer is looking at
 this.

 The partial workaround which will be in 3.10 is that we're marking all
 metadata writes with REQ_META and REQ_PRIO.  This will cause metadata
 writebacks to be prioritized at the same priority level as synchrnous
 reads.  If there is heavy read traffic, the metadata writebacks will
 still be in competition with the reads, but at least they will
 complete.

 Once we get priority escalation (or priority inheritance, because what
 we're seeing here is really a classic priority inversion problem),
 then it would make sense for us to no longer set REQ_PRIO for metadata
 writebacks, so the metadata writebacks only get prioritized when they
 are blocking some process from making forward progress.  (Doing this
 will probably result in a slight performance degradation on some
 workloads, but it will improve others with a heavy read traffic and
 minimal writeback interference.  We'll want to benchmark what
 percentage of metadata writebacks require getting bumped to the head
 of the line, but I suspect it will be the right choice.)

 If you want to try to backport this workaround to your older kernel,
 please see commit 9f203507ed277.


Hi, Ted.
I appreciate for your fantastic explanation. It's really great and very helpful 
for me.
Now i can understand about this issue thanks to you.

Thanks!

Hi, I just wonder. Is there no problem with endianess.
I mean usually bit field is defined with __BIG_ENDIAN_BITFIELD or
__LITTLE_ENDIAN_BITFIELD. But b_jlist and b_modfied is defined with no
pad.
It seems to be good but i just want to make sure.


Thanks.

Re: Re: Re: EXT4 panic at jbd2_journal_put_journal_head() in 3.9+

[EUNBONG SONG]

 Hi all,

 First of all I couldn't reproduce this regression in my sand box.  So
 the following speculation is only my guess.  I suspect that the commit
 (ae4647fb) isn't root cause.  It just uncover a potential bug that has
 been there for a long time.  I look at the code, and found two
 suspicious stuff in jbd2.  The first one is in do_get_write_access().
 In this function we forgot to lock bh state when we check b_jlist ==
 BJ_Shadow.  I generate a patch to fix it, and I really think it is the
 root cause.  Further, in __journal_remove_journal_head() we check
 b_jlist == BJ_None.  But, when this function is called, bh state won't
 be locked sometimes.  So I suspect this is why we hit a BUG in
 jbd2_journal_put_journal_head().  But I don't have a good solution to
 fix this until now because I don't know whether we need to lock bh state
 here, or maybe we should remove this assertation.

 So, generally, Tony, Eunbong, could you please try the following patch?

 Thanks in advance,
 - Zheng


Hi, I tested your patch. Unfortunately, the same problem was reproduced.
Thanks.

Hi, I just wonder. Is there no problem with endianess.
I mean usually bit field is defined with __BIG_ENDIAN_BITFIELD or
__LITTLE_ENDIAN_BITFIELD. But b_jlist and b_modfied is defined with no
pad.
It seems to be good but i just want to make sure.


Thanks.

 Thanks for trying this patch.  Could you please repost the dmesg log for
 me?  I want to make sure whether the second suspicious stuff causes this
 regression or not.  Further, that would be great if you could try to
 comment this line as the following?

Hi, I agree with you.  b_jlist and b_jmodified share the same unit.
I think they are separated.

Hi, I've done git bisect. and panic at jbd2_journal_put_journal_head() is 
caused by

 Hi,

 Bitfields are likely to be implemented using read-modify-write semantics.
 Modifications of either b_jlist or b_jmodified must be done under lock
 since they share same uint. I guess this lock is missing somewhere.
