15 years ago[PATCH] ocfs2 heartbeat: clean up bio submission code
Philipp Reisner [Thu, 11 Jan 2007 09:58:10 +0000 (10:58 +0100)]
[PATCH] ocfs2 heartbeat: clean up bio submission code

As was already pointed out Mathieu Avila on Thu, 07 Sep 2006 03:15:25 -0700
that OCFS2 is expecting bio_add_page() to add pages to BIOs in an easily
predictable manner.

That is not true, especially for devices with own merge_bvec_fn().

Therefore OCFS2's heartbeat code is very likely to fail on such devices.

Move the bio_put() call into the bio's bi_end_io() function. This makes the
whole idea of trying to predict the behaviour of bio_add_page() unnecessary.
Removed compute_max_sectors() and o2hb_compute_request_limits().

15 years agoocfs2: introduce sc->sc_send_lock to protect outbound outbound messages
Zhen Wei [Wed, 24 Jan 2007 01:19:59 +0000 (17:19 -0800)]
ocfs2: introduce sc->sc_send_lock to protect outbound outbound messages

When there is a lot of multithreaded I/O usage, two threads can collide
while sending out a message to the other nodes. This is due to the lack of
locking between threads while sending out the messages.

When a connected TCP send(), sendto(), or sendmsg() arrives in the Linux
kernel, it eventually comes through tcp_sendmsg(). tcp_sendmsg() protects
itself by acquiring a lock at invocation by calling lock_sock().
tcp_sendmsg() then loops over the buffers in the iovec, allocating
associated sk_buff's and cache pages for use in the actual send. As it does
so, it pushes the data out to tcp for actual transmission. However, if one
of those allocation fails (because a large number of large sends is being
processed, for example), it must wait for memory to become available. It
does so by jumping to wait_for_sndbuf or wait_for_memory, both of which
eventually cause a call to sk_stream_wait_memory(). sk_stream_wait_memory()
contains a code path that calls sk_wait_event(). Finally, sk_wait_event()
contains the call to release_sock().

The following patch adds a lock to the socket container in order to
properly serialize outbound requests.

[PATCH] Keys: Fix key serial number collision handling

Fix the key serial number collision avoidance code in key_alloc_serial().

This didn't use to be so much of a problem as the key serial numbers were
allocated from a simple incremental counter, and it would have to go through
two billion keys before it could possibly encounter a collision.  However, now
that random numbers are used instead, collisions are much more likely.

This is fixed by finding a hole in the rbtree where the next unused serial
number ought to be and using that by going almost back to the top of the
insertion routine and redoing the insertion with the new serial number rather
than trying to be clever and attempting to work out the insertion point
pointer directly.

This fixes kernel BZ #7727.

[MIPS] Alchemy:  Fix PCI-memory access

The problem was introduced in 2.6.18.3 with the casting of some
36bit-defines (PCI memory) in au1000.h to resource_size_t which may be
u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT.

With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed
because the ioremap in arch/mips/au1000/common/pci.c already used the
truncated addresses.
With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan
aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c
fails because the maximum iomem-address is 0xffffffff (32bit) but the
pci-memory-start-address is 0x440000000 (36bit).

To get pci working again, I propose the following patch:

1. remove the resource_size_t-casting from au1000.h again
2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and
necessary here. The 36bit-handling will be done in __fixup_bigphys_addr).

With this patch pci works again like in 2.6.18.2, the gcc-compile warnings
in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

wasn't reported to add_active_regions.  This resulted in free_initmem

CPUs.  If not, it fixes up the interrupt to point somewhere else.
Unfortunately, if an IRQ is unregistered the IRQ descriptor may still

This patch uses snprintf() instead of strcpy() and direct character
pointer manipulation.  It makes the features string building safe and
gets rid of the special case for features output in show_cpuinfo()

Additionally I removed the (int) cast of ARRAY_SIZE, which seems to
serve no purpose.

[IA64] enable singlestep on system call

As is pointed out in
http://www.gelato.org/community/view_linear.php?id=1_1036&from=authors&value=Ian%20Wienand#1_1039,
if single step on break instruction, the break fault has higher
priority than the single-step trap. When the break fault handler
is entered, it advances the IP by 1 instruction so break instruction
single-stepping is skipped, actually it is next instruction which
is single stepped.

This patch modifies this, it adds TIF_SINGLESTEP bit for thread
flags, and generate a fake sigtrap when single stepping break
instruction. Test case in attachment can verify this. Any comments
is welcome.

[IA64] kexec: Move machine_shutdown from machine_kexec.c to process.c

This moves the ia64 implementation of machine_shutdown() from
machine_kexec.c to process.c, which is in keeping with the implelmentation
on other architectures, and seems like a much more appropriate home for it.
