Patch Name: PHKL_37753
Patch Description: s700_800 11.11 SPP fragmentation;AIO;EVP;ufalloc;dup2 race
Creation Date: 08/03/07
Post Date: 08/03/19
Warning: 08/10/16 - This Critical Warning has been issued by HP.
- PHKL_32457 introduces a rare condition that can result in a
hang in the dup2(2) system call. The hang can occur when one
thread of a multi-threaded process is calling dup2(2) while
one or more other threads in the same process is calling
open(2) or close(2) at the same time. When the behavior
occurs, a system may loop in the kernel code with a stack
trace similar to the following:
1) bbds_alloc_first_empty_index+0xd0
2) ufalloc+0x84
3) dup2+0xcc
4) syscall+0x204
5) syscallinit+0x55c
- On a uniprocessor system, this behavior may result in a
system hang. On a multiprocessor system, this may result in
the monopolization of one or more CPUs by looping threads and
could eventually lead to a system hang.
- Additional information on this behavior may be found in
Change Request QXCR1000853594.
- The same behavior is exhibited with superseding patches
PHKL_34024, PHKL_35091 and PHKL_37753.
- To avoid this behavior, HP recommends removing these patches
from systems running multi-threaded applications that utilize
dup2(2) heavily, such as Java applications. Since the
behavior was introduced in 2005, if the patches have been
installed and multi-threaded applications have not exhibited
the hang the patches may not need to be removed.
- The superseded patch, PHKL_32374, does not exhibit this same
behavior. If you choose to remove these patches, HP
recommends that PHKL_32374 be installed after they are
removed to ensure as many known issues a possible are
addressed. If PHKL_32374 was installed prior to these
patches, it will automatically be restored when the patches
are removed and will not need to be re-installed.

Processes get deactivated due to memory pressure.
The processes don't get reactivated even when free
memory is increased. The memory pressure is undue as
there are free memory pages on the superpage pool.
Reports generated using kmeminfo tool show a lot of
memory on the superpage free pool.

When applications that use chroot() system call are
operated on a directory with the following properties
1. When accessed, autoFS will mount a filesystem
on this directory using direct map.
2. The mount operation has not taken place on this
directory when chroot() is called on it.
many unusual failures are encountered. One such application
is ftp where operations like put, mput, etc., will fail
with an error message when performed on a directory with
the above mentioned properties. An example of such error
message is shown below.

Defect Description:
PHKL_37753:
( QX:QXCR1000594064 SR:8606501605 CR:JAGag50353 )
A blocking file lock request can be canceled by sending a
SIGINT(CTRL-C) to the server. This is not handled properly
by the client, which may result in the client acquiring the
file lock instead of canceling it. The lock is improperly
obtained by the client and is not properly unlocked while
closing the file.
Resolution:
A kernel parameter called "nfs_voncelocked" has been
introduced by setting a flag in the vnode to determine
whether or not to issue an unlock request while closing
NFS files. The default value of 0 indicates that an unlock
request will not be issued. A value of 1 indicates that
an unlock request will be issued.
PHKL_35091:
( QX:QXCR1000559133 SR:8606431099 CR:JAGaf90541 )
Vnode meta data is cached on NFS clients. This data does
not always get synchronized as soon as changes are made
to the actual data on the NFS server. This is because NFS
client attribute cache time is not expired. If the file
is removed from the server, lookup operations on the NFS
client may provide stale vnodes causing further NFS
remote procedure calls to fail with the error message
"Stale NFS File Handle".
Resolution:
If an ESTALE error is returned, purge the file handle so
that the cached data does not remain stale and retry
access to the file.

PHKL_32457:
( QX:QXCR1000525994 SR:8606319312 CR:JAGae81802 )
During the dup2(2) processing, the destination fd must be
closed if already opened, and then reallocated in order to
duplicate the source fd. If an open(2) call from another
thread occurs between the close of the fd and the
reallocation of the fd, the destination fd may incorrectly
be used by both the open(2) and the dup2(2) call.
In the case when destination fd is not a valid fd if an
open call from another thread occurs before the fd is
allocated, the destination fd may again be incorrectly
used by both open(2) and the dup2(2) call.
Both the above cases can result in data loss or file
corruption.
Resolution:
The dup2() routine was changed to free and allocate the
file descriptor atomically.
Some user level synchronization is also required to
prevent this race completely. This is now documented
in the dup2(2) man page.
PHKL_32374:
( QX:QXCR1000535964 SR:8606363025 CR:JAGaf23688 )
The problem happens due to improper initialization of a
variable. Due to this, open(2) assumes that a set of file
descriptors are not available when they are. This leads
to an allocation of a file descriptor which is not the
lowest numbered one available for the process.
Resolution:
The variable is initialized properly.

This product update contains minor enhancements required to
enable the HP-UX VFS-AdvSysCall and HP-UX FUSER-Enh.
Resolution:

( QX:QXCR1000530403 SR:8606342243 CR:JAGaf03150 )
1) A flag in the file descriptor was used to indicate if the
file descriptor is registered with an event port. This
implementation cannot fully support registering a file
descriptor with multiple event ports.
2) A race condition exists between registration and
deregistration of a file descriptor with the same event
port. This can result in the file descriptor not properly
flagged to indicate its registration with the event port.
Resolution:
1) The flag in the file descriptor structure is replaced by
a counter to keep track of how many event ports the file
descriptor is registered.
2) The new counter is always incremented (decremented)
accordingly upon successful registration (deregistration).
PHKL_30317:
( SR:8606156998 CR:JAGad26332 )
The exiting thread was waiting for the thread looping inside
the AIO code to finish. The thread inside the AIO code will
call sleep to let the AIO operation finish. As the process
is exiting the sleep will immediately be interrupted and the
thread loops continuously calling sleep and being
interrupted.
Resolution:
The thread which was looping inside the AIO code sets the
EINTR after it is interrupted from its sleep and returns.
PHKL_29826:
( QX:QXCR1000527369 SR:8606326634 CR:JAGae88911 )
When maxfiles tunable is set to 60000, approximately 15
pages are required for a table of pointers on 64 bit kernel.
These 15 pages are carved from the superpage pool from
a 16 page area, the remaining 1 page gets used by normal
arena allocations. When the 15 pages are freed it cannot
coalesce thus adding an entry on the 8 page free list,
the 4 page free list, the 2 page freelist, and the 1 page
free list. The next time we need 15 pages we must carve up
a new 16 page and the process repeats. Thus leading to
superpage pool fragmentation.
Resolution:
A request for anything between 14 and 16 pages is rounded
up to 16 pages. This will lead to an extra allocation of
maximum 2 pages, but fragmentation of superpage pool will
not happen in case when maxfiles is set to 60000.
( QX:QXCR1000523049 SR:8606306720 CR:JAGae69754 )
When a process has ~60000 open file descriptors and
it does a close on any of the file descriptors, it
walks each file descriptor to check for a flag.
This is done while holding a spinlock. Since the
spinlock is held for a long time, it leads to a
panic on a debug kernel and performance loss on a
perf kernel.
Resolution:
When a lock is acquired on a file, a flag is set.
On first close of the file if the flag is set, the lock
is released for the whole file.

As a user program opens a large number of file descriptors,
more time is spent in the file allocation routines because
of the current linear algorithm which results in a
performance decrease.
Resolution:
The solution to this problem is to implement a more
efficient algorithm for managing file descriptors.

In a mutlithreaded situtation, socket close(2) can cause a
program to hang as a result of a race condition between the
close(2) and the creat(2) of the socket.
Resolution:
Resolution involved several kernel related subsystems. We
now check to see if a thread in waiting in a state that
could cause a process to block and we abort the call to the
routine that would cause a hang. The patches listed in
other dependencies are necessary to allow and detect an
error code that is necessary for detection of the waiting
thread.

When the system call chroot() is exercised on a directory
with the following properties
1. When accessed, autoFS will mount a filesystem on this
directory using direct map.
2. The mount operation has not taken place on this
directory when chroot() is called on it.
the effective root directory is not assigned with respect
to the automounted filesystem. This results in many
applications (that use chroot()) failing with different
error messages.
Resolution:
Modified chroot() routine in such a way that the effective
root directory is assigned with respect to the automounted
NFS filesystem.

A flag is incorrectly checked when adding a VFS structure
outside of the normal mount code path. The flag is
properly checked in the normal mount code path, so the

This product update contains minor changes necessary to
improve the performance of mount(2) and umount(2) for all
file systems. We incorrectly held a lock to serialize all
access to all file systems for mount/umount service calls.
These file systems specific operations are already
serialized where necessary, and the additional higher
level serialization results in unnecessary performance
degradation.
Resolution:
Removed the unnecessary use of a file system lock that used
to unconditionally serialize all access to all file systems
for mount/umount service calls.

Device major numbers are currently assigned the value 0xff.
This value can not be used in /etc/mnttab, which needs a
value between 0x0 and 0x7f.

range.

opendir(3C) uses open(2) and stat(2) calls, each with path
name parameters. With large numbers of directories, there
are multiple calls to open(2) and stat(2).
Resolution:
open(2) already has access to the information provided by
stat(2) to opendir(3C). opendir(3C) uses open(2) with a new
parameter to gain access to this additional information,
thus avoiding the additional call to stat(2).
( QX:QXCR1000506726 SR:8606178913 CR:JAGad48138 )
The mechanism for retrieving information about mounted
file systems from the kernel is extremely inefficient.
Its cost is essentially a quadratic function
of the number of mounted file systems.
Resolution:
Added a new system call to retrieve information for all
currently mounted file systems, which makes the performance
linear with the number of mounted file systems.

( SR:8606175337 CR:JAGad44579 )
It is not efficient to use the alpha semaphore to serialize

( QX:QXCR1000512778 SR:8606248238 CR:JAGae14638 )
creat(2) races with unlink(2) allowing a ENOENT failure.
Resolution:
The function that creates a file, vn_create(), was
modified to return a referenced vnode to the open
function, vn_open(), thereby eliminating the original
race with unlink(2).
PHKL_26099:
( SR:8606233922 CR:JAGae03145 )
rename(2) always gets the file system semaphore,
even though it is not needed for mp safe file systems,
which include HFS and JFS.
Resolution:
rename(2) will only get the file system semaphore
for file systems that are not mp safe.
Enhancement:
No (superseded patches contained enhancements)
PHKL_30557:
Support added for VFS-AdvSysCall and FUSER-Enh.
PHKL_29759:
This patch enables new functions that will be
called by the HP-UX VFS-Enh.
PHKL_27800:
Enhancements added to disallow mounting another
file system within a VxFS 3.5 Cluster mount and to
remove VxFS 3.5 entries from VFS switch table, when
this product is configured.
Additional enhancements were delivered in a patch
this one has superseded. Please review the Defect
Description text for more information.
